Continuous sewage methane extraction and ventilation device for sewage treatment

Abstract

The invention discloses a continuous sewer methane extraction and ventilation device for sewage treatment, and relates to the technical field of sewage treatment. The problems that a current sewer channel mainly ventilates through a wellhead of a sewer, ventilation efficiency is insufficient, and sewer methane in the sewer cannot be removed substantially are solved. The continuous sewer methane extraction and ventilation device for the sewage treatment comprises an explosion-proof water tank. The top part of the explosion-proof water tank is fixedly provided with a top cover by bolts, and thetop side edge of the explosion-proof water tank is provided with a rubber sealing ring. The middle of the top part of the top cover is fixedly provided with a middle plate through bolts. One side of the top part of the top cover is fixedly provided with a motor through bolts. The arrangement of the explosion-proof water tank and an air-tight sleeve provides an explosion-proof function for the ventilation device. The sewer methane is output intermittently in the form of bubbles to isolate the sewer methane and provide the anti-explosion function for the sewer methane, safety guarantee is greatly provided to avoid accidents in the ventilation device.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a continuous sewer biogas extraction and ventilation device for sewage treatment. Background technique [0002] Biogas, also known as methane, refers to a flammable mixed gas produced by microbial fermentation of organic substances in an anaerobic environment, and its main components are methane and carbon dioxide. The mixture of biogas and air can form an explosive gas. If the concentration of biogas in the air is between 5.5% and 16%, it can explode if there is an open flame. A biogas explosion will generate high temperature, high pressure, shock waves, and emit toxic gases. There is methane in the sewer because the surrounding residents are not aware of environmental protection, so that the pipes that originally flowed sewage are filled with too much domestic garbage, and it is easy to form methane when it is blocked. In the long sewer channel, the air is not circula...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a continuous sewer biogas extraction and ventilation device for sewage treatment, to solve the problem that the current sewer channel proposed in the background technology is mainly ventilated through the wellhead of the sewer, and the ventilation efficiency is insufficient. The function of auxiliary collection cannot remove the methane in the sewer to a large extent, which poses a great safety hazard and is not conducive to safe use.
