Aerated anti-crust biogas digester

Abstract

The invention relates to a biogas digester and aims to provide an aeration type anti-crusting biogas digester. The biogas digester can prevent raw materials from crusting, can remove H2S gas and can maintain the temperature of the biogas digester. According to the technical scheme, the aeration type anti-crusting biogas digester is characterized by comprising a tank, wherein a biogas pipe, a feeding pipe and a discharging pipe are arranged on the tank; the feeding pipe is connected with a feeding tank; the discharging pipe is connected with a discharging tank; an adjusting valve is arranged in the feeding pipe; in the tank, an impeller is rotatably located under an outlet of the feeding pipe around a horizontal axis through a driving shaft and the two ends of the driving shaft are respectively connected with a reciprocated type aerator through a transmission mechanisms; in the reciprocated type aerator, a plunger is located in a plunger slot of a shell in a sliding form; a gas inlet and a gas outlet which are communicated with the plunger slot are formed in the shell; check valves are arranged on the gas inlet and the gas outlet.

Description

technical field [0001] The invention relates to a biogas digester, especially capable of automatically preventing crusting of raw materials in the pond and eliminating H 2 S biogas digester. Background technique [0002] As a big energy consumer, the development and utilization of new energy is of great significance to the sustainable development of the national economy. With the rapid development of rural social economy, rural energy consumption is also increasing. In this context, biogas resources are an extremely important The development and utilization of new energy with application prospects is an effective measure to solve the problem of rural energy supply under the situation of energy shortage, and its development has been paid more and more attention by the country. [0003] However, there are certain defects in the existing biogas digesters: after the biogas digesters have been in operation for a period of time, some of the daily fermented raw materials float up ...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain defects in the existing biogas digesters: after the biogas digesters have been in operation for a period of time, some of the daily fermented raw materials float up due to buoyancy and produce scum, which in turn forms crusts, which cover the liquid surface , affecting the gas production; at the same time, the anaerobic environment in the biogas digester will produce H 2 S, H 2 S is not only poisonous, but also corrodes pipes
