technical field

The utility model belongs to the field of waste gas purification equipment, in particular to an atomization spraying high-efficiency absorption tower.

Background technique

The absorption tower is an environmental protection device that absorbs or purifies pollutants, and there are many types of absorption towers. The packed absorption tower is an important part of the absorption tower. The absorption tower uses the contact between the gas and the liquid to transfer the pollutants in the gas to the liquid, and then separates the clean gas from the liquid that has absorbed the pollutants, so as to achieve the purpose of cleaning the flue gas. At present, the commonly used absorption tower is a packed tower. The gas enters from the bottom of the packed tower, and the spray liquid flows down from the top of the tower. The spray liquid and the gas can be fully contacted in the packing, so as to facilitate the spray liquid to remove pollutants in the packing. Fully absorbed, and then the spray liquid falls back to the bottom of the tower body and continues to spray down from the top of the tower through the circulating pump. However, because the contact area between the tower spray liquid and the gas pollutants is not ideal, the efficiency of the absorption tower is low.
