Description

This is especially true for chemical plants, steel mills, pharmaceutical plants, coking plants, and oil refineries.

Currently, waste gas treatment devices often use adsorption tanks with activated carbon as the primary adsorption filler, combined with functional filter elements to filter and purify the waste gas.

[0003] In addition to harmful flue gases, the interior of the exhaust gas also contains a large amount of smoke particles. In order to efficiently adsorb the harmful substances in the exhaust gas and avoid smoke particles clogging the adsorption filter element, a dust removal structure needs to be installed on the air inlet side of the adsorption tank. The dust removal structure in the existing adsorption tank is arranged in a counter-plate structure. Although it has a good filtering effect, it is easy to cause particles to adhere due to the straight-through structure, and the service life is short and requires regular cleaning. In addition, for the adsorption filter element structure, the existing adsorption tank mostly adopts an integrated filling filter element structure, and the activated carbon is concentratedly filled inside the integrated filter element.

[0034] The working principle or structural principle is that during operation, the exhaust gas is passed through the air inlet end pipe 3 and is filtered by the dust removal filter cartridge 7 to remove the smoke particles. After that, the flue gas flows through the first group of catalytic reaction filter elements 12. The harmful substances in the flue gas are degraded by the catalytic reaction of the catalytic substances in the catalytic reaction filter element 12.

In the adsorption cylinder seat 14, the flue gas is fully in contact with the adsorption activated carbon in the adsorption filter element 13. The adsorption filter element 13 is used to complete the adsorption and purification treatment of the harmful substances.
