[0002] In industrial production processes, dust collection spray towers are widely used for waste gas treatment, especially in environments with high dust levels. These towers capture and remove particulate matter from waste gases by spraying water mist. However, spray towers generate large amounts of wastewater during operation. This wastewater contains numerous impurities, and direct discharge not only wastes water resources but also pollutes the environment. Therefore, effectively treating and recycling this wastewater has become a crucial issue in industrial production.
[0003] Currently, existing wastewater treatment technologies using dust removal spray towers typically employ simple filtration devices. However, after a period of use, the filter screens are prone to clogging, making cleaning very difficult and usually requiring manual disassembly and cleaning, which is time-consuming and labor-intensive.
[0004] Therefore, we propose a wastewater recycling device for dust removal spray towers. Utility Model Content
