Defoaming marsh gas tank

Abstract

The invention discloses a defoaming biogas digester, which comprises a gas storage chamber and a fermentation chamber, and also includes a stirrer, an annular hole is opened on the outer wall of the gas storage chamber, and the stirring shaft of the stirrer extends into the fermentation chamber through the annular hole , the stirring shaft is provided with a stirring blade located in the fermentation chamber, a card cover is set on the stirring shaft located outside the gas storage chamber, a discharge pipe is provided in the fermentation chamber, and a discharge cover is provided at the outlet of the discharge pipe, The top of the air storage chamber is fixedly connected with a solar heat collector, and the solar heat collector is connected with a heat collection return pipe, the stirring shaft is a hollow stirring shaft, the stirring blade is a hollow stirring blade, the hollow stirring shaft and the hollow stirring The blades are provided with defoaming holes, and the top of the stirring shaft is connected with a vacuum defoamer. The present invention can maintain a good temperature in the fermentation chamber by arranging a solar heat collector, and the motor drives the paddles to rotate to generate a vortex, which can fully decompose the fermentation raw materials, thereby increasing the biogas output.

Description

technical field [0001] The invention relates to the technical field of biogas, in particular to a defoaming biogas digester. Background technique [0002] Biogas is a mixture of various gases, the main component of which is methane. People often say that biogas fermentation refers to the process in which biogas bacteria decompose organic matter and produce biogas. According to the role of various bacteria in the biogas fermentation process, biogas bacteria can be divided into two categories. The first type of bacteria is called decomposing bacteria, and its function is to decompose complex organic matter into simple organic matter and carbon dioxide. Among them, there are bacteria that specialize in decomposing cellulose, called cellulolytic bacteria; bacteria that specialize in breaking down protein, called proteolytic bacteria; bacteria that specialize in breaking down fat, called lipolytic bacteria; the second type of bacteria is called methane-containing bacteria, us...

AI Technical Summary

Problems solved by technology

Although hydraulic biogas digesters have the above advantages, there are also many disadvantages: First, due to repeated changes in air pressure, this has a negative impact on the strength of the pool body and the stability and improvement of the combustion efficiency of lamps and stoves.

However, due to the unreasonable structural design of this patent document, the scum in the pool is easy to crust and difficult to break, so the utilization rate of fermentation raw materials is not high, and the gas production rate is very low.
