Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recovery devices, in particular to a wastewater recovery device for a spray tower. Background Art

[0002] A spray tower is a gas-liquid generating device and gas purification equipment, mainly used in the field of environmental waste gas treatment. It usually includes a box body, circulating liquid, packing layer, atomization layer, spray layer and other parts. The working principle of the spray tower is mainly to make the waste gas fully contact with the liquid, and use the solubility of the waste gas in water or through chemical reactions to reduce its concentration, thereby converting it into clean gas that meets national emission standards.

[0003] When the spray tower is working, it uses a spraying method to perform treatment operations, which will generate corresponding wastewater. The wastewater needs further recycling and treatment operations. When the wastewater is recycled and treated, it is usually carried out in the corresponding wastewater recovery device. There are many types of wastewater recovery devices on the market. Most of them add liquid medicine to make the wastewater generate precipitation or convert ions in the wastewater into other substances. However, this type of wastewater recovery device can complete the wastewater treatment operation when used, but it has the defect of not being able to separate the sediment and the water body. The subsequent addition of the separation step is more troublesome, which brings inconvenience to the user. In view of this, we propose a wastewater recovery device for a spray tower.
