Description

A purification device for waste gas treatment

technical field

The utility model belongs to the technical field of purification devices, in particular to a purification device for waste gas treatment.

Background technique

Activated carbon adsorption box is more suitable for waste gas treatment with large air volume and low concentration in waste gas treatment equipment. Activated carbon adsorption tower has the advantages of high adsorption efficiency, wide application, convenient maintenance, and can treat a variety of mixed waste gas at the same time. Activated carbon can remove formaldehyde, benzene, etc. Activated carbon is a very good adsorbent. It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in the gas phase to achieve the purpose of deodorization. . It is also the main material of activated carbon adsorption box. The organic waste gas is powered by the fan, and the positive pressure or negative pressure enters the activated carbon adsorber tower. Due to the unbalanced and unsaturated molecular attraction or chemical force on the solid surface of the activated carbon, when the solid surface is in contact with the gas, It can attract gas molecules to concentrate and keep them on the solid surface, so that the pollutants are adsorbed. After the exhaust gas passes through the filter, it enters the equipment dust removal system, and the purified gas is discharged up to the standard.

In the existing purification device for waste gas treatment, the filter material placed in the device is usually activated carbon molecules. Due to the high-strength filtration performance of activated carbon, multi-purpose filtration can be performed during use, including odor and harmful substance filtration. When using filtration, since the exhaust gas is filtered, the gas enters through one side of the box and is discharged from the other side. During filtration, the activated carbon filter is easy to accumulate a lot of dust, etc., and the dust is easily blocked for a long time. The filtration efficiency of the device is a problem, so we propose a purification device for waste gas treatment.
