Exhaust pressure relief buffer device for sewage pipeline

Abstract

The invention relates to the technical field of sewage pipelines, in particular to an exhaust pressure relief buffer device for a sewage pipeline. The device comprises a shell, a pressure relief device, a liquid drainage one-way valve, a buffer pipe, a movable frame, buffer fan blades, a filter plate and a gas outlet pipe. According to the invention, a movable pipe, an elastic plate and the buffer fan blades mounted on the mounting frame capable of moving along a sliding groove are used for eliminating the kinetic energy of gas, and gas injection caused by continuous accumulation of gas in the pipeline is avoided. In addition, sewage is isolated through the movable pipe, the situation that normal conveying of the sewage in the sewage pipeline is affected due to the fact that the sewage flows out of the gas outlet pipe is avoided, practical significance and popularization value are achieved, and it is expected that good economic benefits can be generated.

Description

technical field [0001] The invention relates to the technical field of sewage pipelines, in particular to a sewage pipeline exhaust pressure relief buffer device. Background technique [0002] Sewage in a broad sense includes domestic sewage, industrial wastewater and runoff sewage, which are generally collected by urban pipes and canals and should be treated by urban sewage treatment plants before being discharged into water bodies. In addition to containing a large amount of organic matter, germs and viruses in urban sewage, due to the high development of industry, the volume of industrial wastewater (accounting for about 60-80% of the total urban sewage), the water quality is becoming more and more complex and the pollution of runoff sewage is becoming more and more serious, making urban sewage Contains various types and degrees of various toxic and harmful pollutants, so they must be collected through sewage pipes for unified treatment before they can be discharged. [...

Problems solved by technology

[0003] Because the humus in the sewage will produce gas under the action of bacteria and continue to accumulate in the pipeline, when the pressure of the gas continues to rise and reaches a certain level, there will be an air spray phenomenon, and the failure of the air spray will destroy the sewage in the pipeline. The normal transportation in the pipeline affects the follow-up work of sewage treatment. Although some pipelines are equipped with exhaust devices, it is very easy to be blocked by foreign matter in the sewage and the exhaust function will be affected.
