Exhaust Gas Treatment Wet Scrubber is a new type of gas purification treatment equipment. The wet scrubber is composed of tower body, trays, reboiler and condenser. It is developed on the basis of the floating packing layer gas purifier. It is widely used in the pretreatment of industrial waste gas purification and dust removal, with perfect purification effect. For the coal gasification process, gas scrubbing is inevitable, regardless of the coal gasification technology, this unit operation is adopted. Because its working principle is similar to the washing process, it is named washing tower. 

The Wet Scrubber is the same as the rectification tower and consists of a tower body, trays, reboiler and condenser. Since the scrubber is a rough separation device, the number of trays is generally small, generally not more than ten stages. The scrubber is suitable for the crushing of mixed gas containing a small amount of dust. The components will not react, and the product should be easy to liquefy. Impurities such as dust (also called high boiling point substances) are not easy to melt or solidify. When the mixed gas enters the scrubbing tower from the middle of the scrubbing tower, because there is product component liquid between the trays, the product component gas is liquefied in the evaporation part, and the impurities cannot be liquefied or solidified when passing through the trays. Liquid It will be fixed by the product component liquid to produce a washing effect. 

The Wet Scrubber is designed and manufactured according to this principle. The product component gas is liquefied in the evaporation part, and the impurities cannot be liquefied or solidified when the liquid passes through the tray, but will be fixed by the product component liquid to produce a washing effect. The scrubber is designed and manufactured according to this principle. The product component gas is liquefied in the evaporation part, and the impurities cannot be liquefied or solidified when the liquid passes through the tray, but will be fixed by the product component liquid to produce a washing effect. The wet scrubber is designed and manufactured according to this principle.

The basic principle of industrial waste gas treatment scrubber is to make gas and liquid contact, and transfer the pollutants in the gas to the beverage. The packing spray absorption tower is produced with PP as the main raw material, and the packing adopts PP material Pall ring or hollow sphere. According to the gas absorption process at the gas-liquid two-phase interface, the transfer rate is proportional to the interface area. Fillers are used to increase the contact area of the two phases, so that the two steps are fully dispersed. Then the clean gas is separated from the contaminated liquid to achieve the purpose of purifying the air.

The gas is forced into the equalizing chamber of the purification tower by the fan, first enters the bubbling section for bubbling treatment, and then undergoes multi-stage packing, spraying, and spraying treatments, so that the gas-liquid two phases are fully reversed to cause neutralization and absorption reactions. Then move forward. To the filler layer, it reacts with the spray liquid. According to the gas purification conditions and other indicators, a three-stage packing spray device can be installed. After the liquid enters the liquid removal device, it is discharged into the atmosphere, and the treated gas meets the national emission standard.
