Rotary washing type automatic anti-crusting methane tank

Abstract

The invention relates to a rotary washing type automatic anti-crusting methane tank. The invention aims to provide a methane tank, which has the function of automatic crusting resistance on the raw materials, can be used continuously, does not require increased maintenance workload and is safe and convenient for usage. A technical scheme is as below: the rotary washing type automatic anti-crusting methane tank comprises a tubular fermenting tank; the top of the fermenting tank is provided with an outlet and sealed by a top cover; the tank top is equipped with a biogas pipe inletting into a tank chamber and for leading out biogas; two opposite sides of the fermenting tank is equipped with a feed inlet and a discharge port, which respectively communicate with a feed inlet tank and a discharge tank through pipelines; the fermenting tank is characterized by comprising a rotary washing type automatic anti-crusting apparatus; the apparatus comprises a collection pool installed below the feed inlet to receive liquid state raw materials, an annular pipeline communicating with a scupper of the collection pool and encircling on an internal face of the fermenting tank, and a ball float type valve installed at the scupper position of the collection pool; and the annular pipeline is provided with a plurality of spray nozzles orientating the internal face of the fermenting tank.

Description

technical field [0001] The invention relates to a biogas digester, in particular to a biogas digester which can automatically prevent crusting of raw materials in the pond. Background technique [0002] In recent years, with the increasingly serious energy contradiction, building a conservation-oriented society has become the fundamental way to solve the problem. As a high-quality, clean and renewable bioenergy, biogas has been widely used across the country. However, there are certain defects in the existing biogas digesters, among which the encrustation of raw materials is the main problem to be solved. Due to the uncoordinated feeding ratio of feces and water in the process of using the biogas digester, and at the same time, the material is not discharged and stirred in time, resulting in less water in the fermentation room, and a large amount of organic acid produced during the fermentation process accumulates, causing the fermentation raw materials to float. The shell...

Problems solved by technology

Due to the uncoordinated feeding ratio of feces and water in the process of using the biogas digester, and at the same time, the material is not discharged and stirred in time, resulting in less water in the fermentation room, and a large amount of organic acid produced during the fermentation process accumulates, causing the fermentation raw materials to float. The shell will hinder the accumulation of biogas generated in the pool, reduce the effective volume and gas storage chamber, reduce the utilization rate of raw materials, and reduce the gas production.

When the incrustation is severe, the biogas digester cannot be used normally and will be discarded, resulting in waste of resources and energy; therefore, solving the incrustation problem is an important condition for the promotion of biogas projects in the construction of new rural areas
