Waste gas purification system for atmospheric pollution treatment

Abstract

The invention relates to a waste gas purification system for atmospheric pollution treatment. The waste gas purification system comprises a purification bin, an air inlet pipeline arranged on one sideof the purification bin, a plurality of filter boxes which are slidably connected into the purification bin and used for containing adsorption substances, a first waste hopper arranged between the purification bin and the filter boxes, an exhaust pipeline arranged at the top of the purification bin, an induced draft fan arranged on the side, away from the purification bin, of the exhaust pipeline, a driving mechanism arranged between the filter boxes and the purification bin and used for driving the filter boxes to slide in the purification bin, a dumping mechanism arranged on the filter boxes, a lifting mechanism arranged between the purification bin and the first waste hopper, a dust filtering mechanism arranged on the air inlet pipeline and used for primarily filtering dust in waste gas, a spraying mechanism arranged between the filter boxes and the air inlet pipeline and used for further adsorbing dust in the waste gas, and a waste liquid recycling mechanism arranged below the spraying mechanism and used for filtering the waste liquid subjected to dust adsorption and then recycling the waste liquid. Workers can conveniently replace adsorption substances.

Description

technical field [0001] The present application relates to the field of exhaust gas purification, in particular to an exhaust gas purification system for air pollution control. Background technique [0002] The waste gas emitted by industrial production mainly includes dust particles, flue gas, odorous gas, toxic and harmful gas, etc., which often have harmful effects on the environment and human health. Before being discharged into the atmosphere, purification measures should be taken to make it meet the waste gas emission standards. This process is called exhaust gas purification. Commonly used exhaust gas purification methods are: absorption method, adsorption method, condensation method and combustion method. [0003] When the adsorption method is used to purify the exhaust gas, the harmful substances in the exhaust gas are usually adsorbed by the adsorbent. The adsorbent is generally activated carbon. However, after the adsorbent is used for a long time, the adsorption ...

AI Technical Summary

Problems solved by technology

[0003] When the adsorption method is used to purify the exhaust gas, the harmful substances in the exhaust gas are usually adsorbed by the adsorbent. The adsorbent is generally activated carbon. However, after the adsorbent is used for a long time, the adsorption efficiency decreases. When the adsorbent needs to be replaced, It needs to be replaced manually by the staff, and there are many harmful substances on the adsorbed substances, which will have a certain impact on the health of the staff

[0004] In view of the related technologies mentioned above, the inventor believes that there is a defect that it is inconvenient for staff to replace the adsorbed substances
