Exhaust Gas Cleaning System Washing Tower

Equipment introduction: The washing tower is a kind of exhaust gas cleaning system washing tower. It is produced based on the improvement of the floating packing layer gas purifier. It is widely used in the pretreatment of industrial waste gas purification and dust removal, and the purification effect is perfect. For the coal gasification process, gas washing is inevitable, and this unit operation is used regardless of the coal gasification technology. Because its working principle is similar to the washing process, it is named washing tower. It is suitable for the treatment of waste gas with low concentration and non-single components. The fine dust, smoke and grease can be removed through the water shower tower. The activated carbon adsorption tower absorbs the treated waste gas. The function of the water shower tower is to purify the waste gas and prevent particles. The like substances block the activated carbon adsorption tower and reduce the adsorption efficiency.

Sub-product introduction: acid mist exhaust gas washing tower; scrubbing tower composite photo-oxygen catalytic purifier;

Working principle: The washing tower comprises the tower body, packing, gas-water separator, liquid distributor, spray system, circulating water tank, circulating water pump, chemical storage and dosing system and other units. The scrubbing tower can also be called a spray tower or a water shower tower. The packing layer in the tower is used as a mass transfer device for the contact components between gas and liquid phases. The bottom of the packing tower is equipped with packing support plates, and the packing is placed on the support plates in a random pile. A packing pressure plate is installed above the filling to prevent it from being blown by the rising airflow. The spray liquid is sprayed onto the packing from the top of the tower through the liquid distributor and flows down the surface of the fill. The gas is fed in from the bottom of the tower. After being distributed by the gas distribution device, it continuously passes through the gaps in the packing layer in countercurrent with the liquid. On the surface of the packing, the gas and liquid two phases are in close contact for mass transfer.
