Description

[0001] The present invention relates to a domestic fog filter system for removing fine dust,

The present invention relates to a domestic fog filter system for removing fine dust, and in particular, to provide a domestic fog filter system for removing fine dust, which is improved in structure to solve a sterilization problem of a humidifier and a virus propagation problem of a filter.

The development of industry and the progress of urbanization, especially the influence of yellow dust generated in China, are increasing the incidence and frequency of fine dust. As the concentration of fine dust in the atmosphere increases, the incidence of disease increases and industrial damage also occurs. According to the data of Korea Environmental Policy Evaluation Institute, it is estimated that up to 5 trillion won Or more.

The dust particles generated from power generation facilities, automobiles, and industries are seriously affecting the health of the people directly. Therefore, there is a policy to reduce the generation of fine dusts both domestically and externally. It is also important to reduce the generation of fine dust, and it is also important to remove the generated fine dust so as not to affect people's health. In particular, fine dust such as sand dust is not reduced by abatement policy and technology alone. Therefore, it is very important to develop the technology for removing the generated fine dust.

It is very important to develop fine dust removal technology that adversely affects not only industry but also general life. Currently, various filters (Bag Filter, Electrostatic Precipitator, HEPA Filter, etc.) are applied. However, There is a limit to removal.

In particular, ultrafine particles having a size of 0.1 μm or less, 0.1 to 1.0 μm particles, and 1 to 10 μm particles are distributed in the atmosphere. Depending on the distribution of each particle, the filter method is different and ultrafine particles are very difficult to remove. Particles smaller than 10 μm can be removed by a high performance filter such as a HEPA filter, but can be removed by a high performance filter such as a HEPA filter. However, these HEPA filters are used to remove particles in a clean space such as a clean room, and expensive operation of these filters is required.

On the other hand, a humidifier is being used to remove fine dust from the home or from the home and provide adequate humidity. In such a humidifier, water droplets are made up from the water in the water tank by the ultrasonic wave generated from the ultrasonic generator, and the principle is used. In this case, there is a problem that the microorganism virus is proliferated due to the suspended matter contained in the water because the water is stagnant in the water reservoir. In order to remove such microorganism virus, disinfecting with a disinfectant or putting a disinfectant in water, however, the disinfectant contained in the water is contained in the water droplets, causing a social problem such as a human being sucking the disinfectant component scattered and scattered in the air, There is a concern.

On the other hand, in the case of removing fine dust with a filter containing a fiber component or the like, there is a possibility that the collected fine dust stagnates on the filter and becomes a factor of virus propagation. These viruses are likely to produce bad odors or harmful gases, which may adversely affect the user's respiratory system.

A home fog filter system 100 (hereinafter, referred to as a "fog filter system") for removing fine dust according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4B.

FIG. 1 is a schematic flow chart for explaining a fog filter system according to an embodiment of the present invention, FIG. 2 is a schematic flow chart for explaining a fog filter system according to another embodiment of the present invention, and FIG. FIGS. 4A and 4B are conceptual diagrams for explaining the process of collecting fine dust by the droplet of the present invention. FIG.

1 and 3, the fog filter system 100 according to the present invention includes a main body 170; A high pressure generating unit 110 for supplying water supplied from the main body 170 at a high pressure; A nozzle unit 130 including a fog nozzle 135 for spraying high-pressure water generated by the high-pressure generating unit 110 into fine droplets; A chamber 140 provided in the main body 170 so that the droplet sprayed from the fog nozzle 135 can collide with fine dust contained in the air flowing in and flowing through the air flow unit 120; And a piping unit 150 for supplying water to the high-pressure generating unit 110 and discharging fine dust and water collected under the chamber 140.

The main body 170 preferably includes a material such as plastic that can maintain its beauty because it forms an outer appearance. The main body 170 is provided with an inlet for supplying water including water not shown and a mixture of droplets mixed with the fine dust And an air inlet and an air outlet through which the air is introduced and discharged. Further, it is preferable to provide a passage through which an electric wire capable of supplying external power can be inserted and removed.

The high-pressure generating unit 110 includes a motor (not shown) (for example, a DC motor or the like) that rotates by a power source applied to a portion where the inflow water is pressurized and a plunger type that generates high- Pressure pump.

The air flow unit 120 includes, for example, a fan that sucks the air introduced into the home into the chamber 140 and discharges the air. The air flow unit 120 may be provided on a suction side where air is introduced or a discharge side where air is discharged, or may be provided on both the suction side and the discharge side, if necessary. However, since the discharge side contains more moisture than the inflow side, consideration should be given to selecting the material.

The nozzle unit 130 is a region for changing the high-pressure water generated in the high-pressure generating unit 110 into a fine liquid droplet. The nozzle unit 130 includes a nozzle header 133 including a pipe for maintaining high-pressure water, It is preferable that the fog nozzle 135 is provided in the amount required to be set and set in the fog nozzle 133. By this structure, high-pressure water is sprayed into the chamber 140 and becomes fine droplets.

The chamber 140 is provided in various forms, and the fine droplets to be sprayed are mixed with the air that is introduced into the inside of the chamber 140. The dust and the droplets of the fine particles are combined with each other to trap the fine particles, Falls down to the chamber 140 and is discharged from the chamber 140 in the form of a mixture of water and fine dust particles.

A process in which the droplets and the fine dust particles are coupled to each other in the downward direction in the chamber 140 will be described with reference to FIGS. 4A and 4B.

That is, when a fine droplet is injected from the fog nozzle 135, a fine droplet is sedimented by adhison with fine dust particles suspended in the introduced air to form a fine dust particle Can be removed.

The smaller the size of dust particles or droplet (droplet) particles, the longer the suspension time in the air becomes. The longer the particles are suspended in the air, the higher the collision probability between particles. When the particle size is small, it floats by Brownian motion and does not settle. If the size of the fine particles is 1 to 10 탆, they float in the air without sedimentation due to their own weight. In this process, when the droplet particles approach and adhere to the dust particles, the weight becomes heavy and sedimentation occurs due to their own weight.

When floating in the air, fine particles of water are formed on the surface of the water particles (energy layer), fine dust particles are bonded to the energy layer of the water droplet particles, and the self weight is increased by the bonding, The mixture in which particles and water droplets are combined becomes precipitated.

The efficiency with which fine dust particles are removed (optionally filtered) in the fog filter system 100 during the testing of the present invention is determined by the fluid velocity (or particle velocity), the high pressure The size of the droplets, the size of the fine dust particles, and the like. In addition, as the size of the droplet is smaller, the energy layer due to ions on the surface of the droplet is increased, so that the adhesion efficiency between the particles is improved first.

If the diameter of the fog nozzle 135 is too small, the droplet is too fine to be evaporated so that the dust particles can not be collected. If the diameter of the fog nozzle 135 is too large, The surface area of the entire droplets with respect to the flow rate is reduced, and the dust particle removal efficiency is very low. From the various experimental results, it is preferable that the size of the droplet generated in the fog nozzle 135 is 50 μm or less. Here, the size of the droplet is more preferably in the range of 15 to 30 mu m.

The shape of the chamber 140 is a vertical shape in which air is introduced into the lower side of FIG. 1 and air is discharged upward, and a cyclone shape as shown in FIGS. 2 and 3, And a horizontal type that flows. In addition, although not shown, the chamber 140 may also be provided in a zigzag shape in which the flow direction is changed according to need, so that the time required for the air to stay in the chamber 140 may be prolonged.

The piping unit 150 includes a cushion tank (not shown) in which water is supplied to the high pressure generating unit 110 and temporarily stores water supplied to the high pressure generating unit 110, A check valve, an on-off valve, and a solenoid valve as required.

The control unit 160 controls the various electromagnetic parts constituting the present invention to perform automatic and manual operation, etc., and also has a setting button (not shown) for setting necessary on-off switches (not shown), various numerical values, And a display member (not shown) for displaying the status.

FIG. 3 is an illustration showing an example in which the fog filter system 100 according to the present invention is packaged for home use. Here, the length (see L in FIG. 3) and the length (see W in FIG. 3) are 400 to 500 mm and the height (see H in FIG. 3) is about 700 to 800 mm.

The operation of the fog filter system 100 according to the present invention will now be described.

First, when the power is applied from the controller 160, the motor and the pump operate to transfer high-pressure water from the high-pressure generating unit 110 to the nozzle unit 130, so that fine droplet particles are sprayed into the space in the chamber 140. At the same time, when air is introduced into the chamber 140 through the air flow unit 120 including the fan, fine dust particles and water droplets in the air float, and they are coupled to each other and move downward due to their own weight. The precipitated mixture is discharged to the outside through the lower side of the chamber 140.

In this one operation example, when the pressure of the high pressure generating part 110 is 70 kg / cm 2 (error range: ± 5%) and the diameter of the fog nozzle 135 is in the range of 0.15 to 0.2 mm, The flow velocity of the air is preferably in the range of 1 to 0.2 m / sec or less.

In this process, a small amount of moisture in the chamber 140 is circulated through the control unit 160 without supplying water to the nozzle unit 130, and the process of drying the chamber 140 is performed for a few minutes The moisture in the circulating air passage can be removed or dried in the chamber 140. [

Thus, according to the present invention, since the water is not stagnated, it is not necessary to use the sterilizing agent, and the problem caused by the sterilizing agent of the conventional humidifier can be prevented. In addition, water supplied including tap water is supplied to the nozzle unit 130 by operating a small high-pressure pump by the rotational force of the DC motor to generate fine droplets in the fog nozzle 135, Uncoordinated water droplets can be released into the atmosphere to control humidity. On the other hand, since the water droplets combined with the fine particles fall down to the lower part of the chamber 140 and are discharged to the outside together with water for a few minutes, there is no need to use a disinfectant because water is not accumulated in the chamber 140.

In addition, since the filter including the bending filter and the Mambrain filter is not used in the air passage, it is possible to prevent the problems such as odor and virus generated due to the fine dust collected in the filter, and the pollution of the circulated air can be solved .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the invention. will be. The scope of the invention will be determined by the appended claims and their equivalents.
