Unpowered automatic baffling type biogas generating device

Abstract

The invention provides an unpowered automatic baffling type biogas generating device. A solar greenhouse and a biogas generating device arranged in the solar greenhouse are included; the biogas generating device includes a sewage collection sedimentation pond, a feeding chamber, a baffling biogas digester, a biogas slurry temporary storage tank and a solid-liquid separation tank; the bottom of thebaffling biogas digester is connected to a biogas slurry discharging pipeline; the top end of the biogas slurry discharging pipeline is flush with the top of the sewage collection sedimentation pond;the baffling biogas digester includes a concrete pool, a black film and a sunlight board, wherein the black film and the sunlight board cover the top of the concrete pool; multiple baffle plates fitting with the two sides of the concrete pool are arranged in the concrete pool; the multiple baffle plates divide the concrete pool into multiple baffling chambers, and water valves are arranged at thebottoms of two adjacent baffling chambers; and the top of the concrete pool is provided with a biogas output pipe. The unpowered automatic baffling type biogas generating device is convenient in maintenance and can make biogas production performance very stable.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a non-powered automatic deflecting biogas generating device. Background technique [0002] Farm sewage is a key area of ​​national environmental governance at present and in the future. Biogas technology is the preferred technology for the harmless and resourceful treatment of farm sewage, and other sewage treatment technologies do not have cost advantages. my country has been promoting biogas sewage treatment technology for many years. Farms generally have various types of biogas of different scales. However, more than 80% of biogas projects are in a state of disuse and shutdown. The main reason is that the operating costs are too high and the profits of the farms cannot support ; Daily operation and management are troublesome, maintenance is not in place, and the operation effect is getting worse; it is difficult to discharge materials, easy to crust, and gradually scr...

Problems solved by technology

my country has been promoting biogas sewage treatment technology for many years. Farms generally have various types of biogas of different scales. However, more than 80% of biogas projects are in a state of disuse and shutdown. The main reason is that the operating costs are too high and the profits of the farms cannot support ; Daily operation and management are troublesome, maintenance is not in place, and the operation effect is getting worse; it is difficult to discharge materials, easy to crust, and gradually scrapped

[0003] The existing baffled biogas has the advantages of no need for stirring, low energy consumption, convenient operation and high efficiency, and can withstand load changes. However, it is easy to deposit and crust during operation, and it is not easy to clean, which reduces the anaerobic fermentation space. , even scrapped in severe cases

At the same time, the existing deflected biogas insulation design is not perfect, the work efficiency is low in winter, the gas production is reduced, and the sewage treatment effect is poor

When cleaning and maintaining the existing baffle biogas digesters, the top cover must be opened to completely pump out the liquid in the middle baffle chamber
