Toxic and hazardous gas multi-level filtering device and gas filtering method

Abstract

The invention discloses a toxic and hazardous gas multi-level filtering device and a gas filtering method. The filtering device comprises a housing. The housing is internally provided with multiple levels of dissolving tanks. The neighboring dissolving tanks are separated by a separating plate. Each separating plate is provided with a gas communication hole and a liquid communication hole. The outer side of the first level of the dissolving tank is provided with an air inlet and a liquid outlet, the outer side of the last level of the dissolving tank is provided with an air outlet and a liquidinlet, and along an air inlet direction, the heights of the liquid outlet, the multiple liquid communication holes, and the liquid inlet are successively increased. The middle of the housing is provided with a rotatable rotation shaft. Each dissolving tank is internally provided with a turntable. The turntable is fixedly installed on the rotation shaft. The turntable is provided with an adsorbate. The adsorbate is soaked by dissolving liquid in the corresponding dissolving tank. Toxic and hazardous ingredients in the gas are adsorbed by the infiltrated adsorbate, and the adsorbed toxic and hazardous ingredients are dissolved in the corresponding dissolving tank through the dissolving liquid. The toxic and hazardous gas multi-level filtering device has the advantages of greatly improving aremoval rate of the toxic and hazardous ingredients.

Description

technical field [0001] The invention relates to a gas filtering device, in particular to a toxic and harmful gas multi-stage filtering device and a gas filtering method. Background technique [0002] With the increasing air pollution, especially the toxic and harmful gases produced in the production process of some enterprises, these gases seriously threaten human health. Therefore, it is particularly urgent to take effective and effective filtration and purification of gases. At present, most industries use multi-layer filtration, mist-liquid spraying and other methods of filtration. For multi-layer filtration, toxic and harmful components in the air, dust, etc. are easy to block the filter layer. Even if anti-blocking measures such as back blowing are taken, the filter screen needs to be replaced regularly; for fog liquid spraying, the method of recycling can reduce the amount of spray liquid waste, but the liquid needs to be replaced after a certain period of time.

Problems solved by technology

For multi-layer filtration, toxic and harmful components in the air, dust, etc. are easy to block the filter layer. Even if anti-blocking measures such as back blowing are taken, the filter screen needs to be replaced regularly; for mist liquid spraying, the method of recycling can reduce the spray liquid waste, but the liquid needs to be replaced after a certain period of time

Therefore, there are various drawbacks, complicated equipment and high cost in this type of method.
