Description

Green energy power generation device and method thereof

The present invention relates to a green energy power generation device and method that is environmentally friendly and improves power generation efficiency.

According to the so-called "sustainable development", it is a process of economic growth while taking into account environmental sustainability. At present, the world continues to advocate energy conservation and carbon reduction. In addition, the so-called green energy is also called clean energy or renewable energy. Its advantages are that it is relatively friendly to the environment and has low greenhouse gas emissions. It can generate an endless supply of energy through the cycle of nature.

In addition, for power generation, power plants that usually use biogas for power generation mainly use food waste or pig manure, which results in an increasing amount of biogas residue, of which the food waste biogas residue rate is about 30% and the pig manure biogas residue rate is about 60%, which all require additional treatment.

As for the production of alcohol, the raw materials of alcohol are usually extracted from plants. Most of them use starch (corn, cassava, sweet potato, barley, wheat, oats, rice, etc.) and sugar (sugar cane, beet) as raw materials for refining alcohol. However, the biggest problem encountered by general alcohol plants is that the generated sludge cannot be processed. The sugar liquid left after refining the alcohol is all waste. In the early days, anaerobic treatment such as sedimentation tanks was used. However, if the output is too large, the scope of the sedimentation tank must be expanded to enable it to discharge wastewater, otherwise the sludge will increase.

Therefore, for the production of alcohol, some manufacturers use sweet sorghum to produce ethanol. Usually, the sweet sorghum stems are first cleaned mechanically and then pressed to obtain sugar liquid, and then the sugar liquid is concentrated to obtain sugar juice. The concentration of the sugar juice is then adjusted to obtain dilute sugar juice, the pH value is adjusted and penicillin is added, and then the sugar juice is added for fermentation. Finally, it is refined to obtain ethanol, and then dehydrated to obtain undenatured ethanol.

However, the above alcohol production process does have the following problems and deficiencies when used and needs to be improved:

Although sweet sorghum is used, the processing process is cumbersome and complicated. If the sweet sorghum is harvested in excess, the storage capacity cannot be increased. Therefore, the sugar solution must be concentrated and penicillin must be added as a preservative to prevent it from becoming rancid. In addition, after concentration, it must be reduced back to sugar solution and then turned into sugar juice, with the sugar concentration of the sugar juice being 13 degrees or 16 degrees. This is a waste of resources. Many processes will waste costs, and the use of preservatives will produce toxins, which will inhibit the bacteria and reduce the fermentation effect. As for the power plant, although the power plant can generate electricity from biogas produced by kitchen waste and pig manure, as mentioned above, the biogas residue rate of kitchen waste is about 30%, and the biogas residue rate of pig manure is about 60%, which makes it impossible to improve the power generation efficiency.

Therefore, how to solve the above-mentioned problems and deficiencies in usage is the direction that the applicant of this invention and related manufacturers engaged in this industry are eager to study and improve.

The main purpose of the subject of this invention is to provide a method that can obtain a total sugar concentration of 16 to 20 degrees by obtaining crop raw materials and pressing them, and then produce high-concentration ethanol with a volume ratio of 97.3% to 97.9% after fermentation, preheating, condensation treatment, distillation tower, methanol tower, etc., and the waste sweet wine mash can be anaerobic fermented, and the biogas produced thereafter can be used to generate electricity, so that the volume ratio of the secondary sludge does not exceed 6%, and the power generation efficiency can reach more than 90%.

The main structure of the present invention that can achieve the above main purpose includes a pressing device for receiving a crop material and pressing it, a fermentation device for producing a mature fermented mash is arranged on one side of the pressing device, a distillation system connected thereto is arranged on the side of the fermentation device away from the pressing device, the distillation system includes a first mash preheater, a recovery tower connected thereto is arranged on one side of the first mash preheater, and a second mash is arranged in the recovery tower. A mash preheater is provided, and a crude wine tower connected to the recovery tower is provided on one side, a first condenser connected to the crude wine tower is provided on one side, a crude wine pump connected to the first mash preheater is provided on one side, a crude wine preheater connected to the crude wine pump is provided on one side, a water washing tower connected to the crude wine preheater is provided on one side, a light wine preheater connected to the light wine preheater is provided on one side, and a water washing tower connected to the light wine preheater is provided on one side. A first condenser is connected to the first mash preheater, a crude wine pump is connected to the crude distillation tower, and the reflux tank is connected to the distillation tower; a second condenser is connected to the second condenser, a reflux tank is connected to the second condenser, a processor is connected to the reflux tank, and a methanol tower is connected to the processor; the first condenser is connected to the first mash preheater, the crude wine pump is connected to the crude distillation tower, and the reflux tank is connected to the distillation tower; furthermore, the distillation system is separated from the fermentation device A solid-liquid separation device is provided on one side for separating the solid and liquid of the waste sweet wine mash to produce a wet solid residue and a dilute wine mash. An anaerobic fermentation treatment system connected to the solid-liquid separation device is provided on one side of the solid-liquid separation device. A biogas power generation device is provided on the side of the anaerobic fermentation treatment system away from the solid-liquid separation device. In addition, the anaerobic fermentation treatment system is connected to the fermentation device, and the biogas power generation device is connected to the anaerobic fermentation treatment system. The above structure can be used in accordance with the following steps. First, a pre-treatment step is performed. A crop material is first taken and pressed by a pressing device to obtain a sugar solution. According to the amount taken, molasses in an appropriate proportion is added to adjust the total sugar sag of the sugar solution to 16 to 20 degrees, thereby completing the pre-treatment step. Thereafter, the adjusted sugar solution is added to yeast in a fermentation device for fermentation to produce a mature fermentation mash, and the mature fermentation mash is further fermented. After preheating, the wine enters the recovery tower and is preheated twice in the first mash preheater and the second mash preheater in sequence. After preheating, the wine enters the crude distillation tower, and the wine vapor is condensed by the first condenser to form crude wine. The crude wine can be sent to the crude distillation tower and a crude wine preheater by a crude wine pump. The preheated crude wine will enter a water washing tower for negative pressure extraction to form light wine. The light wine is preheated and then sent to a refining tower. The refining tower processes the preheated wine. The alcohol vapor produced by the heated light wine is used to obtain a liquid material through a second condenser, and the liquid material enters a reflux storage tank, and a part of the liquid material is refluxed to the distillation tower, while the other part of the liquid material enters a processor for treatment, and the liquid material after the processor enters a methanol tower to adsorb the liquid material and remove the residual methanol and impurities in the liquid material to produce a volume ratio of 97.3% to 97. 9% high-concentration ethanol, and finally the waste sweet wine mash produced after the production of high-concentration ethanol is used to produce wet solid residue and dilute wine mash through a solid-liquid separation device, and the wet solid residue is used as livestock feed, and the dilute wine mash is anaerobic fermented through an anaerobic fermentation treatment system, and then biogas and biogas are produced, of which the biogas is used to generate electricity through a biogas power generation device, and the generated electricity is supplied to the steam chamber for necessary power supply.

The above technology can be used to solve the existing problems in alcohol production and power plants. Although sweet sorghum is used, the processing process is cumbersome and complicated. If the sweet sorghum is harvested in excess, the storage capacity cannot be increased. Therefore, the sugar solution must be concentrated and then penicillin must be added as a preservative to prevent it from becoming sour. In addition, after concentration, it must be reduced back to sugar solution and then turned into sugar juice, so that the sugar concentration of the sugar juice is 13 degrees or 16 degrees. This wastes a lot of resources. Multiple processes will waste costs, and the use of preservatives will produce toxins, which will inhibit the bacteria and reduce the fermentation effect. As for the power plant, although the power plant can generate electricity from biogas produced by kitchen waste and pig manure, as mentioned above, the kitchen waste biogas residue rate is about 30%, and the pig manure biogas residue rate is about 60%, which makes it impossible to improve the power generation efficiency. This will solve the problem of the above-mentioned advantages of the present invention.

When this project intends to produce high-concentration ethanol and generate electricity, several important processes must be carried out as follows:

(a) Pre-treatment step: first, a crop material 1 is taken and pressed through a pressing device 2 to obtain a sugar solution, and molasses is added in an appropriate proportion according to the amount taken to adjust the total sugar concentration of the sugar solution to 16 degrees to 20 degrees, thereby completing the pre-treatment step;

(b) Fermentation step: adding yeast to the adjusted sugar solution in the fermentation device 3 for fermentation 3 to produce mature fermentation mash A;

(c) Step of producing crude wine: the mature fermented mash A enters a distillation system 4, is preheated by a first mash preheater 41 in the distillation system 4, and then enters a second mash preheater 421 in a recovery tower 42 for secondary preheating. After preheating, it enters a crude distillation tower 43, and the wine vapor in the crude distillation tower 43 is condensed by the first mash preheater 41 and a first condenser 44 connected to the first mash preheater 41 to form crude wine B;

(d) Step of producing light wine: the crude wine B is sent into the crude distillation tower 43 and a crude wine preheater 46 by a crude wine pump 45, and the crude wine B passing through the crude wine preheater 46 will enter a water washing tower 47 for negative pressure extraction to form light wine C;

(e) Transport preheating step: the light wine C enters a light wine preheater 48 for preheating and then is sent to a distillation tower 49;

(f) Condensation step: The distillation tower 49 uses a second condenser 50 to obtain a liquid phase material from the alcohol vapor generated by the preheated light alcohol C;

(g) Processing step: the liquid phase material enters a reflux storage tank 51, and a portion of the liquid phase material refluxes into the distillation tower 49, while the other portion of the liquid phase material enters a processor 52 for processing;

(h) Removal step: the liquid phase material after being treated by the processor 52 enters a methanol tower 53 to adsorb the liquid phase material and then remove the residual methanol and impurities in the liquid phase material to produce a high-concentration ethanol with a volume ratio of 97.3% to 97.9%; and

(i) Power generation step: using the waste sweet wine mash 8 produced after the production of high-concentration ethanol, a solid-liquid separation device 9 is used to perform solid-liquid separation to produce a wet solid residue 10 and a thin wine mash 12, and the thin wine mash 12 is subjected to anaerobic fermentation in an anaerobic fermentation treatment system 13 to produce biogas, which is then used in a biogas power generation device 14 to generate electricity.

A more detailed explanation of the above power generation step (i) is as follows:

Steps (c) to (h) belong to the distillation system 4, which can produce alcohol or distilled water, and step (i) is the field of power generation and application. In step (i), the waste sweet wine mash 8 produced after steps (c) to (h) is a strong wine mash, and the waste sweet wine mash 8 is separated into solid and liquid by a solid-liquid separation device 9 (i1), and the wet solid residue 10 is produced. It is used as livestock feed 11, and the remaining liquid part forms a dilute mash 12. The dilute mash 12 can undergo (i2) anaerobic fermentation treatment step, including an anaerobic fermentation treatment system 13. The biogas produced after the anaerobic fermentation treatment system 13 can be used to generate electricity through a biogas power generation device 14, and the remaining biogas residue 15 is discharged. In addition, in the anaerobic fermentation treatment step, the excess biogas liquid can be fermented again. Furthermore, the heat generated by the biogas power generation device 14 can be given to a steam chamber 6, and a boiler 7 is used to cooperate with the steam chamber 6 so that it can provide the necessary heat source for the distillation system 4.

Among them, the solid-liquid separation device 9 is a solid-liquid separator, which mainly uses centrifugal force and specific gravity difference to filter and separate solids (particles) and liquids.

The processor 52 is a condenser or an evaporator.

The total sugar content of step (a) is preferably between 18 and 20 degrees.

The optimal volume ratio of step (h) is 97.6%, and the amount of electricity generated by biogas power generation is mainly determined by the chemical oxygen demand (COD) value. Taking sweet sorghum as an example, the chemical oxygen demand (COD) values of sweet sorghum waste liquid and molasses waste liquid are both 150,000 to 200,000, and at present, 100,000 can reach a power generation of 2000KW/HR.

The crop raw material 1 is taken as an example of a biomass ethanol crop, and the biomass ethanol crop is one of sugarcane, sweet sorghum, or beetroot.

The anaerobic fermentation treatment system is a single tank, double chamber, three-phase anaerobic treatment system, which can mainly treat high-strength solid and liquid wastes, and has a high efficiency of about 93% methane conversion rate, and only about 6% of the chemical oxygen demand (COD) value is converted into sludge, and 1% of the chemical oxygen demand (COD) value remains in the sludge. The so-called single tank, double chamber means that a tank is divided into an inner chamber and an outer chamber, and the so-called three phases include the first Phase 1: The treated material first enters the low-speed outer chamber of the fermentation tank, the liquid will flow into the inner chamber, and the solids will stay until the hydrolysis process is completed before entering the inner chamber; Phase 2: The high-speed inner chamber integrates the dual treatment functions of the anaerobic sludge bed and the multi-layer fixed biomass membrane medium; Phase 3: Part of the slurry treated in the inner chamber flows back to the outer chamber for further digestion, and another batch flows to the unit, and the filtered suspended solids flow back to the outer chamber for further treatment.

According to the above steps, when the crop raw material 1 is sweet sorghum, since sweet sorghum has the advantages of easy cultivation, low cultivation cost, short growth period, high land utilization rate compared with other energy alcohol crops, and applicable mechanical sowing and harvesting, reducing labor cost expenditure, etc., using sweet sorghum as crop raw material 1 can make this case have strong competitiveness. In other words, sweet sorghum has strong adaptability to the environment and is durable. It is heat and drought resistant, has a growing period of about 3 months, has strong regeneration ability, can be cultivated as perennial roots, and can produce 3 harvests per year. Sweet sorghum is a variety of seed sorghum, and can produce 5,000 to 6,000 kilograms of seeds per hectare, but the seeds are smaller, with a thousand-grain weight of about 18g to 22g. The plant is tall and has a very high biological yield. The stems are rich in sugar, and the grains can be used as food or livestock feed. In addition, sweet sorghum contains high water-soluble carbohydrates, which can be made into high-quality green storage feed, and combined with winter green corn to facilitate the long-term stable supply of high-quality fodder for cattle and sheep; in addition, its stems contain high sugar and minerals when they are ripe, which can be eaten directly, squeezed into juice, concentrated and ground into powder for quenching for food additives, and can be used as fuel, or the leaves can be mixed with it to make fodder for sale, which can further improve production efficiency. Therefore, sweet sorghum crop raw materials1 can be developed in the direction of diversified utilization, especially as the most advantageous for the production of alcohol, and even the waste sweet wine mash8 produced after the production of alcohol can be used for anaerobic fermentation, and the biogas produced can be used to generate electricity, achieving extremely high power generation efficiency.

As for sugarcane, the annual production is about 90,000 tons of sugar, and the by-product is 17,000 hectares of 95% alcohol. It is easy to cultivate in Taiwan, especially during the summer crop season when the impact of typhoons and heavy rains is relatively low. The average yield of sugarcane is about 78 tons per hectare (the growing period is about 16 months), and it can produce about 5,000 to 6,000 liters of bioethanol.

As for beetroot, it is a major source of sugar besides tropical sugarcane and is also the most important sugar-making crop in temperate regions. Its roots are large and similar to carrots but rich in sucrose, which can produce granulated sugar. Sufficient sunshine and large temperature difference between day and night are conducive to sugar accumulation. Beets grown in high temperature and humid areas have low sugar content.

Please refer to the sixth and seventh figures, which are the step flow chart and packaging schematic diagram of another preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is similar to the above-mentioned embodiment, and both have (a), a pre-treatment step; (b), a fermentation step; (c), a crude wine production step; (d), a light wine production step; (e), a transport preheating step; (f), a condensation step; (g), a treatment step; (h), a removal step; and (i), a power generation step; the only difference is that after step (a), step (a1), a dry packaging step can be performed: the pressed The crop raw materials after being squeezed by the squeezing device 2 can be packaged and dried by a packaging device 16 arranged on one side of the squeezing device 2; (a2), recycling step: the dried crop raw materials are recycled in the industry, and the industry is one of a biomass power plant, a feed plant or a paper mill; of course, the packaging device 16 can also be arranged on one side of the solid-liquid separation device 9 to perform packaging recycling operations. In other words, this case can not only produce high-concentration alcohol and have high power generation efficiency, but also has environmental protection, and the crop raw materials can be recycled and reused to achieve sustainable change.

Please refer to FIG. 8, which is a step flow chart of another preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is similar to the above-mentioned embodiment, and both have (a), a pre-treatment step; (b), a fermentation step; (c), a crude wine production step; (d), a light wine production step; (e), a transport preheating step; (f), a condensation step; (g), a treatment step; (h), a removal step; and (i), a power generation step; the difference is that the crop raw material of the present embodiment is starch. For example, the starch crop is one of potato, cassava, sweet potato, corn, barley, wheat, oats, or rice, and when it is a starch crop, after step (a), a saccharification step (a1) may be performed: after being pressed by a pressing device, saccharification is performed to obtain a sugar solution; the main reason is that the raw materials of crops such as potato, cassava, sweet potato, corn, barley, wheat, oats, or rice are mainly starch, so saccharification must be performed again. The subsequent steps are the same as the above and will not be repeated. In addition, regarding sweet potatoes, sweet potatoes are asexually propagated using tubers and stems, have strong reproductive capacity, and have no strict restrictions on the planting period of sweet potatoes. They can produce a considerable yield in any season. They are not strict about the environment, are easy to cultivate, have a wide range of adaptability, have few risks, are highly stable, and are rich in nutritional value. Therefore, sweet potatoes are also suitable as the crop raw material for this case.

In addition, regarding potatoes, potatoes are widely planted all over the world, with a total global output of 368 million tons. In addition to grains, potatoes are currently the most important staple food crop for humans in the world. They are mainly eaten as underground tubers and prefer cool and dry climates. They have strong adaptability to soil, preferably loose and fertile sandy soil, but require cool, cold and dry climates. Although they can grow in humid and hot areas, they have high nutritional and medicinal value. They are rich in carbohydrates and can provide a large amount of heat energy to the human body. The nutritional components of potatoes are also very comprehensive, containing protein, minerals (phosphorus, calcium, etc.), vitamins and other ingredients. Therefore, potatoes are also suitable as crop raw materials for this case.

In addition, regarding cassava, also known as tree yam, it is a plant of the Euphorbiaceae family, the genus Cassava. The root of cassava can be eaten after peeling and cooking. Therefore, many residents in tropical and subtropical regions grow cassava, and the flour made from it is called cassava flour. In addition, cassava is easy to grow and can be used as a cheap raw material for the production of monosodium glutamate, and can also be used to refine alcohol, used as biofuel and raw material for making cornstarch. Therefore, cassava is also suitable as a crop raw material in this case.

In addition, corn is an important food crop with the highest total output in the world. Corn can also be used as feed and as a raw material for ethanol fuel in the biotechnology industry. There are many varieties of corn, and those with high sugar content are more widely planted.

Therefore, the green energy power generation device and method of the present invention are the key technologies that can improve usage:

First, by obtaining crop raw materials and pressing them with a press 2, a total sugar concentration of 16 to 20 degrees can be obtained, and after fermentation, preheating, condensation treatment, distillation tower, methanol tower, etc., high-concentration ethanol with a volume ratio of 97.3% to 97.9% can be produced, and the waste sweet wine mash 8 can be anaerobic fermented, and the biogas produced thereafter can be used to generate electricity, so that the volume ratio of the secondary sludge does not exceed 6%, and the power generation efficiency can reach more than 90%.

Second, to achieve environmental sustainability, green electricity symbiosis, resource recycling, revitalization of fallow farmland, promotion of agricultural transformation and upgrading, creation of employment opportunities, enhancement of corporate social responsibility, and improvement of power generation efficiency.

Third, reusing biogas slurry can significantly reduce the amount of water required in the fermentation step, which has the advantage of saving water.

Fourth, the biogas slurry does not hinder the efficiency of fermentation. The acetic acid in the mash is completely digested during the anaerobic fermentation, thus achieving the advantage of saving trouble.

Fifth, the dilute mash 12 has a high gas production capacity, thus achieving the advantage of high efficiency.

Sixth, it can reduce the cost of steam production and aerobic sewage treatment expenses, effectively saving costs.

Seventh, the selling price of government-subsidized electricity is more cost-effective than selling syrup and is stable in the long term.
