Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas purifier. Background Art

[0002] An exhaust gas purifier is a device specially used to treat industrial exhaust gas. Its function is to treat and separate harmful substances in the exhaust gas to reduce pollution to the environment and protect human health. The structure and components of the exhaust gas purifier may include but are not limited to: Dust suction duct: used to absorb pollutants in the exhaust gas. High-efficiency filter: used to capture larger suspended particles and other pollutants. Activated carbon filter: uses the adsorption effect of activated carbon to adsorb organic compounds and other harmful substances. Special dust suction fan: provides the necessary wind power to help the transmission and purification process of exhaust gas. Touch-type microcomputer controller: used to control the operating status of the entire system. Exhaust gas purifiers are usually installed in specific facilities, such as factories, workshops or other places where exhaust gas needs to be treated. It can treat many types of exhaust gas, such as dust particles, smoke and soot, odorous gases, toxic and harmful gases, organic waste gas, acid mist waste gas, oil fume waste gas, etc.

[0003] At present, activated carbon waste gas purifiers are widely used in the purification of various industrial waste gases because of their advantages of fast adsorption rate, high adsorption speed and good adsorption effect.

[0004] The existing activated carbon waste gas purifier has a filtering section inside, which is used to place activated carbon to adsorb waste gas, so that the activated carbons are clustered together and cannot contact and adsorb waste gas with the maximum area, resulting in low utilization rate. Moreover, after a period of use, all activated carbons need to be replaced, resulting in a large replacement workload and high activated carbon use costs. At the same time, when replacing, the exhaust gas needs to be stopped, and the continuity of exhaust gas purification cannot be guaranteed, thereby reducing the exhaust gas purification treatment efficiency.
