Controllable box type complete equipment for anaerobic fermentation and methane liquid treatment

Abstract

Disclosed is a controllable piquid of swamp processing equipment, the fermentation of marsh gas system mainly comprises of solar energy heating barn, more than two fermentation of marsh gas pool connected together in-line and its entrance for material and exit for material, feed inlet and discharge outlet auxiliary heating system and other parts. The fermentation of marsh gas pool includes material exhausting chamber, pool and steal cover of it; the solar energy heating barnincludes the frame and plastic film covering on it; the auxiliary heating system comprise of heating furnace and heating recycling pipe which has recycling water pump and value on it, its one end is linking to the material exhausting chamber of fermentation of marsh gas pool and another one to the heating water jacket in the heating furnace, the heating-recycling piquid of swamp recycling auxiliary heating system through the their covers. The invention is an auxiliary heating marsh gasengineering suitable for scalized pig farm, mainly aiming at solving problems existing in conventional marsh gas pool, such as fermentation in low temperature, insufficient time for production, small ratio of volume and productivity and so on. The conventional marsh gas pool cannot assure the stable temperature and productivity for marsh gas, while the engineering makes use of solar energy heating and auxiliary heating equipment, which has solved the problems above completely, and its advantages includes: (1) reasonable in structure and practical in technology; (2) has remarkable economic benefit, high productivity and short term for compensating investment, about 1.23 years; (3) is suitable for payoff pariod and waste water procession in scalized pig farm, with high processing efficiency, has supplied a new processing approach for pig farm .

Description

technical field [0001] The invention relates to an anaerobic fermentation biogas device, in particular to a controllable header type anaerobic fermentation and biogas slurry treatment complete set of equipment. Background technique [0002] 1. Status quo of livestock and poultry manure biogas treatment technology [0003] With the continuous advancement of science and technology, the improvement of people's living standards, and the rapid development of the breeding industry, a large amount of livestock and poultry manure has been produced. Since the 1990s, the excrement discharge of livestock and poultry in my country's breeding industry has increased rapidly. According to incomplete statistics, by the end of 2001, the total amount of excrement and excrement in the whole year exceeded 1 billion tons. Biogas technology is an effective way to solve livestock and poultry manure pollution. The development of biogas fermentation system in our country began in the 1960s and 197...
