Description

Cattle manure energy and resource system

This creation is related to an energy and resource system, especially the use of dry anaerobic ferment technology to process cattle manure and agricultural organic solid waste and produce biogas, biogas residue and biogas liquid to generate electricity through biogas treatment systems and biogas Equipment, biogas residue composting system, biogas slurry treatment system and biogas slurry mixing system that convert biogas, biogas residue and biogas slurry into usable electricity, organic fertilizer and liquid fertilizer.

By the way, milk is rich in calcium, vitamins, minerals... and other rich nutritional values, so it is widely loved by people in China, whether it is used as a nutritional supplement or used for beverage blending, baking... etc. According to statistics, there were more than 60,000 dairy cows bred by domestic dairy farmers in 2018, and the milk production was close to 420,000 metric tons. In addition to dairy cows, there were more than 150,000 cows including edible beef cattle and epidemic cattle. Adult cows can excrete approximately 30 kg of manure per day. Therefore, the amount of manure derived from raising cattle is relatively large. The traditional method is to remove the urine from the cow manure and treat it as a compost, but it takes 3 to 6 months to decompose the organic matter into the organic fertilizer when it is placed in the dumping yard. The composting process is time-consuming, and the efficiency of converting cow manure into fertilizer for reuse is not good.

In order to improve the above-mentioned shortcomings, China Patent No. CN109486865A discloses "a method for anaerobic fermentation of plant waste to produce biogas", which is to pulverize plant wastes and place them in an airtight manner every 2 days. Stir once and leave for 5~7 days, and the livestock and poultry manure is also kept in a closed place. Stir once every 2 days and leave for 5~7 days. Then, mix the plant waste and livestock manure, and add the inoculum to stir anaerobic fermentation 45 ~60 days to produce biogas.

In addition, China Publication No. CN105002221A discloses a "method for intensively resourced organic waste in vegetable areas to produce biogas through high-efficiency anaerobic fermentation", which involves mixing or adding pulverized vegetable waste into an acid-inhibiting microorganism preparation. Fresh cow manure, pig manure, and inoculant treated straw are mixed, and mixed with water to form a mixture with a moisture content of 88-90%. Then, the inoculum is added for anaerobic fermentation to produce biogas.

In view of the traditional method of composting the cattle manure produced by feeding cattle, it has the disadvantage of time-consuming composting process and poor composting efficiency.

Therefore, the purpose of this creation is to mix cow manure with agricultural organic solid waste and decompose the organic matter by dry anaerobic fermentation technology to produce biogas, biogas residue and biogas slurry, which are then used for power generation and composting organic fertilizer respectively. And liquid fertilizer, improve the efficiency of recycling cattle manure resources.

In order to achieve the aforementioned purpose, this creation provides a cow manure energy and resource utilization system, including: a dry anaerobic fermenting system, the dry anaerobic fermenting system includes at least one fermenting tank, located in the fermenting tank containing cattle Manure and agricultural organic solid waste, mixing cow manure and agricultural organic solid waste and anaerobic fermentation to produce biogas, biogas residue and biogas liquid; a biogas treatment system, which includes biogas desulfurization equipment, Water equipment and dust removal equipment. After the biogas treatment system receives the biogas produced by the dry anaerobic ferment system, the biogas is passed through the biogas desulfurization equipment, water removal equipment and dust removal equipment in order for desulfurization, water removal and dust removal. Disposal; a biogas power plant that receives the biogas processed by the biogas treatment system, uses the biogas to generate electricity to generate electricity, and supplies the waste heat generated during the power generation process to the fermentation tank for insulation; a biogas residue composting system, The biogas residue composting system receives the biogas residue produced by the dry anaerobic fermentation system, and turns the biogas residue into organic fertilizer for use in organic farming; a biogas slurry treatment system, which contains biogas slurry Liquid storage equipment and biogas slurry circulating spraying equipment. The biogas slurry treatment system receives the biogas slurry produced by the dry anaerobic fermentation system and stores it in the biogas slurry storage facility, and borrows part of the biogas slurry in the biogas slurry storage facility. The biogas slurry circulating spraying equipment is sprayed on the fermentation tank; and a biogas slurry mixing system, which receives part of the biogas slurry in the biogas slurry storage equipment, and adds adjustment materials and stirs, aerobic aeration and stirring It is then made into liquid fertilizer for use in organic farming.

Based on the above, by mixing cow manure with agricultural organic solid waste and decomposing organic matter through dry anaerobic fermentation technology, biogas, biogas residue and biogas liquid are produced, and the biogas is processed by the biogas treatment system to generate electricity through biogas power generation equipment. The biogas residue is turned through the biogas residue composting system to form organic fertilizer. After the biogas slurry is processed by the biogas slurry treatment system, part of it is sprayed into the fermentation tank, and the other part is poured into the biogas slurry mixing system to make liquid fertilizer, which is then used for the treatment of cattle manure. At the same time, the efficiency produces usable electricity, organic fertilizer and liquid fertilizer, so that the cow manure can achieve the effect of energy and resource utilization.
