Multi-unit umbrella-shaped saturated falling-off type waste gas treatment device

Abstract

The invention discloses a multi-unit umbrella-shaped saturated falling-off type waste gas treatment device, belonging to the technical field of waste gas treatment. According to the invention, a plurality of hollow umbrella-shaped adsorption bodies which are magnetically adsorbed and fixed on a gas guide pipe are arranged in a treatment box; when the hollow umbrella-shaped adsorption body reachesan adsorption saturation state, the internal gas pressure intensity of the hollow umbrella-shaped adsorption body is gradually increased, gas blows an elastic magnetic attraction trigger body, and theelastic magnetic attraction trigger body expands outwards and bulges and then is in contact with a magnetic attraction mechanism; after triggering is completed, the magnetic attraction mechanism doesnot magnetically attract and fix a magnetic attraction sheet any more; at the moment, the saturated hollow umbrella-shaped adsorption body falls off downwards under the condition that the adsorptionbody receives no magnetic force and receives gravity, so a technicist is prompted that the hollow umbrella-shaped adsorption body has been saturated; and meanwhile, a limiting bag connected with the hollow umbrella-shaped adsorption body falls down under the action of gravity and is embedded into the gas guide pipe, so the situation that gas continues to be guided out downwards from the gas guidepipe after the hollow umbrella-shaped adsorption body is separated from the gas guide pipe is effectively avoided, and sealing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, and more specifically relates to a multi-unit umbrella-shaped saturated shedding type waste gas treatment device. Background technique [0002] Waste gas purification treatment mainly refers to the work of treating industrial waste gas such as dust particles, flue gas and dust, odorous gas, and toxic and harmful gases generated in industrial places. Sulfur dioxide, nitrogen oxides and smoke (powder) dust in the exhaust gas are the main air pollutants in my country. Reducing the emission of sulfur dioxide, nitrogen oxides and smoke (powder) dust is not only very important for protecting and improving the atmospheric environment, but also And it's urgent. [0003] The pioneer of exhaust gas purification treatment is none other than filtration. Exhaust gas filtration is the most basic and most important treatment process in exhaust gas purification treatment. In the prior art, cloth bag...

AI Technical Summary

Problems solved by technology

In the prior art, cloth bags and filter screens are often used to filter exhaust gas. During the treatment process, a large number of solid particles and impurities will be adsorbed on the cloth bags and filter screens. When the use time is too long, a large amount of dust will adhere to the surface of the filter material Exhaust gas impurities, the gradual increase in the amount of impurities will directly affect the passing rate of exhaust gas and reduce the filtering effect

Under normal circumstances, when the filter material is saturated with adsorption, it is not easy for technicians to detect it as soon as possible, so it is difficult to replace it in time.
