Description

{System for Removing Malodor using Microplasma Air Ozone}

The present invention relates to a malodor decomposition system, and more particularly, it relates to a malodor decomposition system, and more particularly, it relates to a malodor decomposition system for generating various kinds of odor generating substances generated in a livestock breeding field sequentially by applying a high oxidation technique so as to generate ozone by micro- Which can be removed or decomposed.

Air pollution control that can maintain clean air quality by treating dust, sulfur compound, nitrogen oxides, odor, etc. generated from industrial activities is becoming important, and electric dust collection, desulfurization facilities, And so on.

Especially, since the consumption of meat is increasing due to the improvement of the economic living environment, it is necessary to control the odor generated by various substances in the situation that the shape of the livestock is changed into mass rearing and high density rearing. The domestic swine industry has grown from a large portion of production to sales of 4.7 trillion won in 2009. The number of breeding horses is increasing and the number of households is decreasing, so the number of breeding horses per farm is increasing. Thus, problems related to odor caused by mass rearing are likely to increase.

Odors are defined as the smells of hydrogen sulfide, mercaptans, amines, and other irritating gaseous substances that stimulate the smell of humans to give offensive and repulsive effects. Representative materials include organic acids, alcohols, amines, aromatic compounds, aldehydes, esters, and sulfur compounds. Among them, ammonia, methyl mercaptan, hydrogen sulfide, dimethyl sulfide, methyldisulfide, trimethylamine, n-butyric acid, n-valeric acid, I-valeric acid and the like . However, most of the livestock facility sites that cause serious bad odors are outside the bad odor management area, making it difficult to regulate. Among the odor-emitting industries located outside the odor management area, the livestock facilities, sewage, wastewater, and livestock manure treatment facilities accounted for 82.4% of the total odor emission facilities located outside the odor management area.

In order to reduce the odor generated in livestock facilities, etc., we have strengthened enforcement standards for odor prevention since 2005, and since 2010 we have designated and managed designated hazardous substances for 22 substances. In spite of these efforts, the stench that occurs in various livestock farmers across the country is becoming a social problem that causes inconvenience and disgust to the residents of the area as well as to the passengers passing by. Especially in areas with many tourist attractions, the image of the farmers is badly damaged due to the smell of the farmers, and the local economy is hurting the local economy.

Therefore, in rural areas where coexistence of tourism industry and livestock industry is required, development of odor removal technology is urgently needed. In particular, in the case of livestock facilities where serious odors such as pig farms or poultry farms are continuously generated, it is required to develop a new system that can effectively remove odors without adversely affecting the livestock breeding environment of the livestock.

Ammonia, sulfur compounds and lower fatty acids, which are major odor substances generated in livestock breeding areas such as pig farms, are generally excellent in deodorization by the cleaning method, ozone oxidation method, adsorption method, combustion method, biological deodorization method and deodorant spraying method. However, the combustion method is large, the fuel cost is high, and the harmful components should be considered. In addition, the adsorption method is expensive to replace the adsorbent and is suitable for low concentration. The biological deodorization method requires a large installation area and measures against the temperature are required. And it is difficult to handle alone.

On the other hand, the use of the ozone generator has a risk of inducing respiratory disorder in the livestock being raised, frequent malfunction of the device, and low efficiency of the odor reduction. For example, according to the prior art (Application No. 10-2007-0072805), there has been proposed a technique for removing odors by including an ozone generator that generates ozone by discharging oxygen or air, The ozone is generated by the corona discharge. In a farm environment such as a pig farm, the nitrogen compound reduces the performance of the ozone generator or is adsorbed by the oxygen generator, causing failure. There is a problem that it is difficult to use it as a malodor reduction device.

Therefore, it is necessary to improve the ozone generating apparatus capable of solving the limit of performance deterioration due to the nitrogen compound of the existing ozone generating apparatus, and it is possible to easily decompose odorous substances by appropriately changing the ozone concentration, New practical techniques are required. In particular, it is necessary to develop a malodor reduction system that can effectively remove or decompose various odor generating substances without directly damaging the livestock in a livestock breeding environment.

Disclosure of Invention Technical Problem [8] The present invention has been made in view of the above technical background, and an object of the present invention is to provide an odor decomposition system capable of improving odor treatment efficiency at low cost.

In addition, the present invention provides an integrated processing system in which various odor reduction processes such as dry and wet processes for various odor generating substances utilizing ozone are optimally performed through a single system.

It is an object of the present invention to provide a method and system for treating malodorous substances, which are specialized not only in various wastewater treatment plants where odors are generated but also in animal husbandry facilities where mass rearing is always performed.

Other objects and technical features of the present invention will be more specifically described in the following detailed description.

In order to accomplish the above object, the present invention provides a method of controlling a concentration of ozone in a plurality of chambers, comprising: introducing a gas for removing a malodorous object containing air in a livestock breeding cage into a plurality of chambers successively arranged and connected by mutual flow paths, A system for decomposing various odor generating substances contained in a gas to be deodorized, comprising: an inlet chamber including a blower and an ozone generator for generating microplasma air ozone; and an ozone generator connected to the inlet chamber, A wet chamber for spraying a water or a chemical liquid to clean dust and decompose ammonia, amines and hydrogen sulfide, comprising: a first spray chamber having a relatively large spray droplet size and a second spray chamber having a relatively small size of the spray droplet, A spray chamber connected to the wet chamber, A first dry chamber having a UV lamp and a second dry chamber containing a catalyst filter, the dry chamber being provided with ozone generated in the inlet chamber and decomposing volatile organic substances and volatile fatty acids, Wherein a plurality of microchannels are formed in an insulative support and electrodes are disposed in the insulator support around the microchannels so that the air supplied to the microchannels passes through the microchannels to generate ozone The present invention provides a system for decomposing odorous substances using micro-plasma air ozone.

In the present invention, the first dry chamber may include a first UV chamber and a second UV chamber having different UV wavelengths, and ozone is generated through the first UV chamber to increase the ozone concentration and ozone decomposes through the second UV chamber Thereby reducing the ozone concentration.

Also, in the present invention, the second dry chamber may include a first catalyst chamber including activated carbon and performing physical filtering on the malodor generating material, and a catalyst filter including manganese dioxide and copper oxide to decompose ozone, And a second catalyst chamber for chemically decomposing the odor generating substance using the oxygen active species.

Further, the present invention may further include a demister chamber inserted between the wet chamber and the dry chamber.

According to the present invention, it is possible to effectively decompose and remove nitrogen compounds such as ammonia, volatile fatty acids, and dust, which are major odor substances generated in livestock breeding areas such as swine facilities.

The malodor decomposition system of the present invention can stably deodorize various odor materials generated in livestock facilities by odorous substances through the process of appropriately changing the ozone concentration by combining AOP and scrubber technology and introduces a tunnel type chamber structure In deodorization reaction, sufficient contact time is maintained and deodorization efficiency is increased. These systems are expected to solve the odor problem of livestock facilities facing the livestock industry.

In addition, the system of the present invention can be manufactured in a system of a suitable size according to the scale of a pig farm or a poultry farm, and a module in which decomposition processes of odor generating components such as dust, nitrogen, organic compounds, . Therefore, it is possible to make customized production in accordance with the breeding ground environment, and it can be used as a facility for reducing odors in farms and wastewater treatment plants as well as farms such as pig farms and poultry farms.

Especially, it is possible to secure a good odor reduction performance compared to the equipment production cost, and it can contribute to the environmentally friendly breeding of domestic livestock farmers as well as contributing to the promotion of overseas expansion of the environmental industry. It is expected to be able to do.

The present invention relates to a process for introducing a malodor removing gas containing air in an animal husbandry cage into an inlet of a plurality of chambers arranged in a row and removing various odor generating substances contained in a target gas in a plurality of chambers step by step It suggests a system to remove stench from the pig farm.

In order to increase the efficiency of the malodor treatment, the ozone generated by using air is basically used. In order to prevent damage to the livestock and the failure of the ozone generator in the livestock breeding ground such as the pig farm or poultry farm, Apply ozone generation technology. In order to efficiently produce OH radicals for increasing deodorization efficiency, The generation and decomposition of ozone is appropriately controlled by using the advanced oxidation treatment method (AOP), while the continuous chamber system of the tunnel type scrubber system is applied to maintain sufficient contact time of the deodorization reaction, thereby doubling the deodorization efficiency, Thereby minimizing the emission of ozone.

Ozone can be easily obtained in the field with only air or oxygen and power. Since the required ozone amount can be obtained by changing the applied voltage and frequency of the ozone generator, the injection amount control and automation are easy. Since the oxidation-reduction potential of ozone is higher than that of fluorine, the time for sterilizing and decomposing the object to be treated in water is relatively short. Ozone oxidation is widely used in sanitary and wastewater treatment fields by disinfection, iron and manganese treatment, cyanogen removal, taste, odor treatment, coagulation assistant effect, organic biodegradation promotion, and refractory organic matter treatment. Ozone is decomposed by hydroxyl groups and generates OH radicals through intermediates of hydroperoxy radicals (HO ₂ ^- ), superoxide radicals (O ₂ ^- ), and ozonide radicals (O ₃ ^- ). This OH radical has a higher potential difference than ozone itself (O ₃ : 2.07V, OH radical: 3.08V) and reacts with almost all organic matter at a very high rate. However, it is common that ozone reacts with the majority of foul-smelling odor-causing organic matter in the majority, or the reaction is very low.

In order to compensate for the disadvantages of ozone, the system of the present invention combines AOP technology to accelerate the generation of OH radicals to treat organic materials. The AOP oxidation method is a technique for producing an OH radical as an intermediate product. The pH is adjusted to ozone, or hydrogen peroxide, ultraviolet light or the like is added to increase the oxidizing power.

On the other hand, if ozone is directly supplied to a livestock breeding farm such as a pig farm, a poultry farm, or a livestock farm, the ozone reaction is not effective and the odor reduction efficiency is inferior. Conventional ozone generators use corona discharge (voltage of 5,000 to 10,000 volts). Under these conditions, ammonia in the odor substances is converted into nitrous acid to reduce ozone, thereby reducing the odor reduction efficiency. There is a problem that PSA (Pressure Swing Adsorption) device is broken due to adsorption to the zeolite of the oxygen generator. In addition, since ozone generated by the corona discharge is a poisonous substance having a stimulant odor and has a very strong oxidizing power (oxidation power), there is a risk of causing deterioration of insulation in the long term and causing a flashover (spark discharge). In addition, it affects the breathing of livestock in breeding.

As described above, it is difficult to use an ozone generating device by an oxygen generator and a corona discharge in an animal husbandry environment. On the other hand, in the system of the present invention, the ozone generator generates ozone by using air without an oxygen generator through microplasma, so that it can be effectively used in an animal husbandry hatchery such as a pig farm. This ozone generator inserts electrodes into the microchannel-formed insulator, and air passes through the microchannel of dielectric material to generate plasma at low voltage due to glow discharge instead of corona discharge. Therefore, unlike existing ozone generator, It is possible to generate ozone, and ozone is generated and exhausted in a continuous chamber system, thereby reducing the concentration of ozone and minimizing the impact on the livestock. The detailed structure and operation of the ozone generator of the present invention will be described later.

The system of the present invention using micro-plasma air ozone is advantageous in that the existing ozone generator does not use the oxygen generator when compared with the case where the efficiency of the odor reduction is poor or the oxygen generator is easily broken in the pig farm environment, And safety of livestock in breeding are excellent, economical and commercial value are very high.

The malodor component control technology of the malodor decomposition system according to the present invention basically decomposes the malodorous substance in an environment of livestock breeding environment containing a large quantity of nitrogen due to the effective generation of ozone by air using micro plasma by using micro plasma, (Ozone), hydrogen peroxide, Vacuum UV, UV, photocatalyst, catalytic filter (including thermal catalyst) are combined with ozone to perform stepwise decomposition of odor causing substances such as pig farm. Particularly, while the wet process and the dry process are performed step by step, it is possible to induce generation of a droplet of a proper size per process through a spray system in a wet process, while at the same time improving the physical properties such as ammonia, amines, hydrogen sulfide, volatile fatty acids and volatile organic compounds , A continuous chamber system of a tunnel reaction scrubber structure which effectively controls decomposition by reaction with ozone or OH radical is applied.

For example, dust, ammonia, amines, and hydrogen sulfide are decomposed and removed in the wet cleaning chamber area, such as spray droplets and ozone water, and volatile Organic materials, volatile fatty acids and the like are then decomposed and removed in the dry-promoted oxidation process zone.

In order to perform such a stepwise odor elimination process, the present invention introduces a continuous chamber system, and the structure and characteristics of the system will be described in more detail with reference to the drawings.

1A is a perspective view of a malodor decomposition system 100 of the present invention. The system includes a plurality of chambers arranged in series and connected by mutual flow paths and includes an inlet chamber 130a and a discharge chamber 130b including a blower at an inlet end and an outlet end, And includes a plurality of wet process chambers 110 and a plurality of dry process chambers 120 that are sequentially arranged in a state in which a chamber including a blower is disposed at either the inlet end or the outlet end.

The odor-removing substances contained in the gas to be removed are gradually decomposed while varying the concentration of ozone in the plurality of chambers in a state where the gas for removing odor including air in the livestock cage is introduced into the chamber, The air discharged from the system not only reduces odor substances but also releases the ozone concentration generated in the system, minimizing damage to livestock in livestock breeding grounds.

The system of the present invention may be placed inside a livestock farm, such as a pig farm, The inflow portion of the inflow chamber may be formed in the vicinity of the outside of the breeding ground so as to allow the air inside the breeding ground to flow.

In the present system, the inlet chamber (130 in FIG. 1B, 130a in FIG. 1A) includes a blower 131 and a system control section 132, and an ozone generator described later is built in this control section. The ozone generator generates ozone from the air in the livestock breeding ground supplied to the inflow chamber to supply ozone to each chamber in the system. The inlet chamber is provided with an inlet port 130a and an outlet port 130b on both sides and a front opening 130c on the front side and a front cover (not shown) is mounted there. The outlet of the inlet chamber is connected to the inlet of another adjacent unit chamber by means of a connection tube or the like so that the ozone and the air (including the odor generating substance) in the livestock breeding place are transferred to the adjacent chambers through the inlet chamber.

FIG. 1C shows the structure of the unit chamber 102 in which the process of the present invention is performed. In FIG. 1C, the inlet 102a and the outlet 102b are provided on both sides, and the front cover 102c is mounted on the front And a separation membrane 102d is formed therein as shown in FIG. 2A, so that ozone and air passing through the inlet port flow downward and upward in the chamber. This flow extends the reaction time of the odor generating substance and ozone in each chamber and makes the decomposition action more actively according to the characteristics of the odor generating substance. Each unit chamber is equipped with a supply pipe (or discharge pipe) 102e connected to the inside of the chamber below. The supply pipe serves as a supply passage for water or a chemical liquid in, for example, a wet chamber, and can function as a discharge passage for decomposing odor generating substances in the chamber in other chambers.

In the system of the present invention, the wet chamber 110 may be composed of several spray chambers 111, 112, 113a, and 113b having different sizes of droplets. The wet chamber is connected to the inlet chamber to supply ozone generated in the inlet chamber. As shown in FIG. 2B, water or a chemical liquid is supplied in the form of droplets through the spray 210 to clean dust, while ammonia, , Hydrogen sulfide, and the like. In this process, the concentration of ozone generated in the inlet chamber is continuously decreased. The wet chamber may include a first spray chamber having a relatively large spray droplet size and a second spray chamber having a relatively small size of the spray droplet. For example, the droplet size of the first spray chamber 111 may be at least 1 mm So that the second spray chamber can have a liquid droplet size of less than 1 mm to decompose the water-soluble odor generating substance. The second spray chamber may be divided into a chamber 112 having a droplet size of 100 to 1000 μm and a chamber 113a and 113b having a droplet size of 10 to 100 μm, Depending on the size and the number of livestock being kept, the number and size of the wet chamber can be varied.

The amount of ozone supplied to each chamber varies depending on the amount of air to be removed from the odor. The ozone generator is driven in the inlet chamber so that the concentration of 1 to 20 ppm is supplied considering the size of the livestock breeding ground and the number of livestock. The size of the spray droplet in the wet chamber is related to the dissolution of the dust or ozone to be cleaned. As the droplet size becomes smaller, the surface area becomes larger and the dissolution rate of ozone becomes higher. Therefore, feed dust, dust, It is preferable to adjust the size of droplets in each unit chamber of the wet chamber so that a droplet of 1 mm or less is generated in order to improve the removal efficiency of odor-causing substances such as ammonia and amine nitrogen and hydrogen sulfide.

After the wet chamber, a dry chamber 120 is connected. In the dry chamber, ozone generated in the inlet chamber and supplied through the wet chambers is decomposed into volatile organic substances and volatile fatty acids by the highly oxidizing method. These dry chambers may include first dry chambers 121a and 121b with built-in UV lamps and second dry chambers 122 and 123 with built-in catalyst filters. 2C, the UV lamp 220 may be disposed along the flow path inside the chamber, and the second dry chamber may include various catalytic materials such as activated carbon or manganese dioxide, .

The first dry chamber may include a first UV chamber 121a and a second UV chamber 121b having different UV wavelengths. A UV lamp having a wavelength of 185 nm or 172 nm may be disposed in the first UV chamber, And a UV lamp having a wavelength of 254 nm or 222 nm is disposed in the second UV chamber to remove odorous substances through decomposition of ozone. The second dry chamber includes a first catalyst chamber 122 containing activated carbon to perform physical filtering on the malodor generating material, a second catalyst chamber 122 containing manganese dioxide and copper oxide to decompose ozone to chemically decompose the odor generating material, And may include a catalyst chamber 123. In a dry chamber containing activated carbon, odor substances are removed through physical filtering, and the moisture contained in the air flowing into the chamber is partially removed.

Each of the chambers constituting the dry chamber can have a different number and size depending on the size and the size of the livestock breeding place and the number of livestock being raised. In addition, a demister chamber (not shown) may be inserted between the wet chamber and the dry chamber to enable humidity control in the system and allow the odor decomposition process in the dry chamber to proceed more smoothly.

The malodor decomposition system of the present invention is characterized in that micro-plasma is used in the production of ozone. The ozone generator used in the present invention has a plurality of microchannels formed in an insulative support, electrodes disposed around the microchannels inside the insulator support, air supplied to the microchannels passes through the microchannels, Lt; / RTI >

Generally, a plasma is generated by injecting a gas between two electrodes and applying a high voltage to the electrode to change the gas into a plasma state. The conventional plasma generating apparatus has a large size of the plasma generating apparatus and an excessive manufacturing cost of the plasma generating apparatus because the electrode size or the path through which the gas is injected is large and the high voltage is required. Therefore, the plasma generating apparatus is limited in application to the purifying system using ozone water. For example, in the case of a corona discharge, a high voltage of 7000 to 10000V is required, and a high temperature is accompanied by generation of a plasma, so that a cooling device such as a cooling water or a heat sink is essentially required for raising ozone production efficiency or for safety of the apparatus. In addition, if the pressurized dissolution method is adopted to generate ozone water more efficiently by dissolving the generated ozone quickly in water, a pressurizing means is added so that the whole apparatus becomes more complicated, and there is a disadvantage that the manufacturing cost is increased and the apparatus size is increased .

On the other hand, in the present invention, an ozone generator using a micro plasma, which is a low-pressure plasma at atmospheric pressure, is used. A micro plasma is a plasma having a diameter of several tens to several thousands of micrometers, It is possible to generate an excellent cold plasma plasma even at a level below 2000V, so that a cooling device or a heat sink for heat dissipation is not necessary and a simple air cooling type cooling is possible.

Such a micro-plasma apparatus is significantly smaller in size than other plasma apparatuses and includes an insulator support 300 having a plurality of micro-channels 310 formed therein as shown in FIG. 3A for generating micro- do. The insulating support may be formed of, for example, an oxide material. The microchannel may be formed in the shape of a cylinder or a pipe in the inside of the insulator support and is formed to pass through the other side of the insulator support as shown in Fig. 3B, which is a sectional view taken along the line A-A in Fig. The diameter of the microchannel can be several micrometers to several hundred micrometers in size. Air in the livestock breeding ground enters the micro-channel inlet of the insulator support of the ozonizer disposed in the control unit of the above-mentioned inflow chamber and is converted into ozone by applying high voltage through the electrode disposed on the insulator support, Gas outlet. The micro plasma apparatus includes a power supply unit (not shown) for applying a voltage to form a discharge and a control unit (not shown). The micro plasma apparatus includes a plurality of unit devices shown in FIG. May be used.

The arrangement of the electrodes is also important for generating micro plasma to change oxygen to ozone. In the malodor decomposition system of the present invention, the microplasma ozone generator can be disposed around the microchannel by inserting an electrode in an insulator support to effectively generate ozone while reducing the size. For example, as shown in FIG. 4A, two opposed electrodes 320 can be arranged in the direction of each microchannel. In addition, as shown in FIG. 4B, a plate-shaped electrode 320 may be disposed above and below the microchannel so that a common voltage may be applied to a plurality of microchannels. Depending on the length, diameter, and cross-sectional structure of the microchannel, the shape of the electrode embedded in the insulating support can be changed not only into a plate-like structure but also into a sharp tip or wire. An electrode is embedded in the insulative support and the surface of the microchannel is protected by an insulating layer, so that the electrode can be protected from etching or sputtering caused by the plasma.

Ozone production has been mainly driven by the use of corona discharge or UV. Macroscale plasma has been widely used in livestock hatcheries due to limitations in utilization, problems with initial investment and maintenance costs, and cattle damage caused by ozone generated. . On the other hand, the present invention utilizes micro-plasma, which is one type of atmospheric low-temperature plasma, as a small and light, high-efficiency mobile plasma and ozone supply device, thereby ensuring high efficiency plasma generation and durability and ensuring stable ozone supply. Therefore, it is possible to provide the process innovation of productivity improvement and cost reduction by reducing the initial investment cost and maintenance cost for reducing the odor in the livestock hatchery, and by appropriately changing the concentration of ozone in the chamber system, , While minimizing the amount of ozone in the odor-reducing air discharged from the system, thereby preventing damage to the environment surrounding the breeding habitat and the environment of the breeding habitat.

Figure 5 shows the change in ozone concentration caused by ozone generation and decomposition in each chamber in the system of the present invention. After the ozone is generated, the ozone concentration is continuously reduced by dissolving ozone in the water or chemical solution spray in the wet chamber, and then ozone is generated through the first UV chamber of the first dry chamber, for example, the UV wavelength of 185 nm or 172 nm The ozone concentration is increased and the ozone is decomposed through the second UV chamber having the UV wavelength of 254 nm or 222 nm, so that the increase of the ozone concentration is slowed down. In the second dry chamber, where there is a catalytic filter containing manganese dioxide and copper oxide, the ozone is decomposed and the concentration is continuously decreased to decompose the odor generating substance chemically.

After the ozone is initially generated, the concentration of the ozone is changed several times by each specialized process for increasing the reactivity between the odor generating substance and the OH radical in the chamber system. Finally, the ozone concentration passes through the second catalyst chamber, And the final ozone concentration from the whole system is reduced to the level of 0.05 to 0.1 ppm.

With the change in ozone concentration, various odor reducing substances contained in the air of the livestock breeding place are stepwise removed or decomposed by a specialized process performed in each chamber. Referring to FIG. 6, The degree of decomposition can be schematically confirmed. For example, in the process of supplying a spray of the first large droplet in a wet process, foreign substances such as dust are removed (a), and in a subsequent wet process in which a small droplet is supplied by spraying, ammonia, It is decomposed by ozone (b). Then, volatile fatty acids and volatile organic substances are decomposed stepwise according to their characteristics, through a high-level oxidation process by UV and a physical and chemical decomposition process by a catalytic filter (c, d).

The malodor decomposition system of the present invention controls the decomposition process by using the properties of various odor materials, and in particular, it produces air ozone through microplasma, It is possible to effectively decompose odorous substances and to minimize the amount of ozone discharged to the outside of the system by changing the concentration of ozone in each chamber and process, thereby eliminating the odor in an environmentally friendly manner in a large-scale breeding site such as a pig farm or a poultry farm, Can be greatly contributed to improvement.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modified, modified, or improved.
