Equipment for purifying peculiar smell and waste gas in workshop of sewage treatment plant

Abstract

The invention relates to the field of waste gas treatment, in particular to sewage treatment plant workshop peculiar smell waste gas purification equipment which comprises an L-shaped exhaust pipe mounted on a workshop wall, an exhaust fan arranged in the middle section of the exhaust pipe and an absorption barrel arranged below the exhaust pipe, and a water inlet pipe extending to the bottom of the absorption barrel is inserted into the top end of the absorption barrel. An air inlet pipe is connected to the top end of the water inlet pipe, a mounting frame is fixedly connected to the outer wall of the workshop wall body, a rotating frame is mounted at the end, away from the workshop wall body, of the mounting frame, and two filter cartridges are detachably mounted on the rotating frame. The rotary frame is arranged, the filter cartridges are installed at the two ends of the rotary frame, when the filter cartridges need to be replaced, the old filter cartridges can be directly screwed away, the new filter cartridges are placed between the exhaust pipe and the air inlet pipe, in this way, the operation of replacing the filter cartridges is rapidly completed, shutdown only needs to be carried out for an extremely short time or even does not need to be carried out, and the operation efficiency is improved. And the air quality in a workshop is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to an equipment for purifying odorous waste gas in a workshop of a sewage treatment plant. Background technique [0002] Exhaust gas discharged from industrial production often has harmful effects on the environment and human health. Before being discharged into the atmosphere, purification measures should be taken to make it meet the requirements of exhaust gas emission standards. This process is called exhaust gas treatment. Commonly used exhaust gas purification methods are: absorption method, adsorption method, condensation method and combustion method. [0003] The air composition inside the workshop of the sewage treatment plant is relatively mixed, containing a lot of toxic and harmful gases, as well as some solid-liquid particles. Generally, the waste gas in the workshop is discharged to the outside, and it is absorbed during the process of discharge. The activa...
