A continuous sewer biogas extraction and ventilation device for sewage treatment

Abstract

The invention discloses a continuous sewer biogas extracting and ventilating device for sewage treatment, relates to the technical field of sewage treatment, and solves the problem that the current sewer channel is mainly ventilated through the wellhead of the sewer, and the ventilating efficiency is insufficient, and the sewer cannot be ventilated. The problem of the large-scale removal of biogas inside. A continuous sewer biogas extraction and ventilation device for sewage treatment, comprising an explosion-proof water tank; the top of the explosion-proof water tank is fixed with a top cover by bolts, and a rubber sealing ring is provided on the edge of the top side of the explosion-proof water tank; the top The middle of the top of the cover is fixed with a middle plate by bolts; the top side of the top cover is fixed with a motor by bolts; the setting of the explosion-proof water tank and the air-closing sleeve provides the explosion-proof function for the ventilation device, and the explosion-proof water tank and the air-closing sleeve will The biogas is output intermittently in the form of bubbles, which isolates the biogas and provides an explosion-proof function for the biogas, which greatly provides safety guarantees 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...

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.
