Problems solved by technology

Existing technologies such as upflow anaerobic sludge bed reactor (UASB), internal circulation anaerobic reactor (IC), upflow solid reactor (USR), anaerobic contact digester and other mainstream biogas digesters are limited by cost and Due to technical limitations, the capacity of a single biogas digester is mostly only 1000m 3 About, the hydraulic retention time is less than 20 days, and there is a short-circuit phenomenon o

Embodiment Construction

[0037] The working principle of the present invention will be described first.

[0038] Equipped with constant pressure valve, feeding device, and discharge device; the gas guide pipe is connected to the constant pressure valve to keep the biogas in the gas storage room constant at a certain set pressure value, and the gas pipeline is used for one-way output; the feeding device is equipped with raw material pool, feeding Pipe, return pipe, raw material delivery pipe outside the pond, one-way valve, one end of the feed pipe is inserted into the biogas slurry in the central cylindrical partition wall, and the other end is connected with a one-way valve to communicate with the raw material pool to control that the raw material liquid can only enter the central cylinder in one direction In the shaped separation wall, one end of the return pipe is inserted into the biogas slurry in the fermentation room, and the other end is connected with a one-way valve to communicate with the raw...

Abstract

The invention provides a method for only fermenting and decomposing feces of livestock and poultry, and a method for simultaneously fermenting and decomposing feces of livestock and poultry and other organic waste to producing biogas continuously through an ecological type energy environmental-protection recycling system. The invention further provides a curve tunnel type biogas digester, a device capable for realizing automatic operation without energy consumption, and a device capable of achieving that the operation of the device is controlled remotely through a computer. The building of an oversized biogas digester with the monomer digester capacity of 1000 cubic meters is not limited by the span of a digester cover, and raw materials can be fermented, decomposed and sterilized at room temperature for at least 93 days and then are directly discharged into nature water. The ecological type energy environmental-protection recycling system can be used as a converter of biomass energy and can produce a large amount of biogas in modes of environmental protection, stable yield, low cost and large scale. The difficulties of environmental pollution and energy shortage can be solved, and the economic benefit can also be obtained.

Description

technical field [0001] The invention relates to a biogas production method and an anaerobic fermentation reactor using an eco-energy, environmental protection, recycling and regeneration system. technical background [0002] People have realized in practice that fermenting human and livestock manure with biogas bacteria (ie microorganisms) can kill insects and sterilize bacteria, and obtain high-quality energy and fertilizers. According to measurements, schistosomiasis eggs were killed in 7-22 days under normal temperature biogas fermentation conditions; hookworm eggs had a mortality rate of 75% after 50 days, and all died after 93 days; roundworm eggs had a mortality rate of 75% after 90 days; Salmonella typhi survived The time is only 30 days; Shigella flexneri was isolated after 30 hours and was negative, but it can survive for 17 days in general feces. [0003] There are many types of biogas fermentation devices (anaerobic reactors), all of which can produce gas under s...
