1. Brief introduction of biogas power generation in farms
With the rapid development of the rural economy, animal husbandry has also been greatly improved, has become an important component of the rural economy indispensable. An important source of livestock and poultry manure gradually become China's environmental pollution. According to local conditions to promote biogas project is the effective way to control the pollution of aquaculture. Aquaculture waste resource utilization to achieve also, bring good economic, ecological and social benefits because of its low pollution, low emission, energy saving and other advantages of a series of concern. At the same time, the biogas power generation has become an important measure of green environmental protection.
2. Status and development of biogas power generation
Biogas is a gas which appears with the development of large-scale construction of biogas and biogas comprehensive utilization utilization technology. The research and application of domestic biogas power market is still not perfect. But in the promotion of biogas technology of biomass virtuous cycle, maintaining ecological balance, the development of modern agriculture, improve the living standards of farmers and agricultural guarantee product safety and energy security has been playing an important role. Not only can effectively solve the problem of organic pollution, renewable energy biogas can also produce clean and environmentally friendly and can be converted into electrical energy. So the biogas power generation technology in China will have broad prospects for development. And is an important way to biogas generator treatment of livestock manure harmless, energy recovery and reduction process in the.

3. Farm biogas generator process technology program
(1)The establishment of biogas pool: the working principle of cylindrical hydraulic digester is the pressure air and water compressor. The fermentation tank is made up of liquid level, the upper part is the gas storage room, the lower part is the fermentation room.
(2)The pretreatment process of pig manure: after removal of inorganic substances grille, stone, plastic and other large; dry pig manure is transported to clear fast mixing system, and fully mixing in rapid mixing system, then pump into the anaerobic digestion tank.
(3) Anaerobic digestion process
<1> Feeding method: pig manure is temporarily stored in the solid feed tank, weighing, and then transported to the rapid mixing system by screw conveyor
<2> The configuration of anaerobic digestion tank: the internal shaft stirrer is used to make the feed evenly distributed and fully contact with anaerobic microorganisms, and the temperature of the liquid in the anaerobic digestion tank is even
<3>Insulation and temperature increasing
(4)Biogas slurry treatment process: material by solid-liquid separation, biogas residues were used as organic fertilizer raw materials factory.
(5)Biogas purification: the biogas produced by anaerobic fermentation tank is a mixed gas containing saturated water vapor. Besides CH4 and CO2, it contains H2S and suspended granular impurities. Excessive H2S and impurities will endanger the life of the follow-up equipment, so desulfurization, dehydration and other purification processes need to be carried out.
(6)Heating device spiral plate heat exchanger consists of two parallel metal plates rolled into two spiral channels, cold and hot fluid between the heat exchanger through the wall of the spiral.
(7)Biogas purification process: compressed by choose a suitable adsorbent, using adsorption agent on gas components of selective adsorption on adsorption and adsorption capacity of the group with the pressure increasing, pressure drop characteristics of adsorption component and desorption to the multicomponent gas separation and purification purposes.
(8)Flare system: the role of the torch is to burn excess landfill gas and to dispose of the gas transported to the plant in the case of power generation equipment maintenance
(9)Biogas generator set: the fuel and air injection into the cylinder mixing compression, ignition lead to combustion work, push the piston operation, through the cylinder connecting rod and crankshaft, drive generator power generation.group with the pressure increasing, pressure drop characteristics of adsorption component and desorption to the multicomponent gas separation and purification purposes.
