A water vapor transposition methane producing method and water vapor transposition methane tank

Abstract

The present invention discloses a water vapor transposition fermentation method of methane and methane tank, utilizing the method can implementing water vapor transposition fermentation of methane, capable of generating methane with higher air pressure and automatically breaking crustization formed inside methane tank, and simplify methane tank structure. The present invention cancels traditionary methane tank air chamber, the inlet / outlet pool is high than the fermentation tank which is hemisphere structure, a plurality of monomers can be connected for increasing fermentation tank volume, and inside the methane tank is full of processing water when generating no gas, and when generating gas, the methane pushing part of processing water to water pressure chamber and forming variable air chamber, and the structure implements water vapor transposition fermentation.

Description

technical field [0001] The invention relates to a technique and a device for preparing biogas by anaerobic fermentation of organic waste and liquid organic pollutants, in particular to a water-gas transposition biogas production method of biogas and a water-gas transposition biogas pit. Background technique [0002] At present, biogas technology is playing an increasingly important role in the construction of new rural areas in our country. On the one hand, biogas digesters can process organic waste to generate bioenergy, on the other hand, they can convert manure produced by animal husbandry into organic fertilizers, and can be used for many other agricultural organic matter and Harmful substances can be transformed and harmless in the biogas digester, so biogas can beautify the rural ecological environment. In the rural areas of our country, household biogas is generally the main type, and it is constructed underground. At present, the principle and technology used in bio...

Problems solved by technology

[0004] The national promotion standard biogas digester GB / T4750-2002 "Standard Atlas of Household Biogas Digesters" has the following disadvantages in the process of use: 1. It is designed with an air chamber, which is the upper half of the biogas digester and expands when gas is produced. , it does not change when no gas is produced, so a permanent crust is formed under the air chamber; 2. Due to the existence of the fixed air chamber, the effective fermentation volume is reduced

[0005] The Chinese patents "A Deep Hidden Biogas Digester" and "A Large-capacity Biogas Digester" have the following problems: 1. The excavation depth is too deep, which increases the construction cost and difficulty, especially when the groundwater level is high. Construction; 2. Because the biogas digester is buried too deep and the water head is too high, the pressure of the biogas is too high, and there is no suitable biogas equipment in the follow-up, so it needs to be used at a reduced pressure, which is unnecessary; 3. Because the burial is too deep, the pressure in the biogas digester is high , causing the feed to be blocked, and the microorganisms survive under high pressure, which affects the gas production efficiency
