Description

Technical Field

[0001] This utility model relates to the field of chemical exhaust gas spray treatment technology, and in particular to a chemical exhaust gas spray treatment device. Background Technology

[0002] Spray treatment devices are commonly used equipment for treating chemical exhaust gases. Traditional spray treatment devices are tower-type structures, i.e., spray towers. Existing spray towers are integral structures with multiple layers of spray racks with nozzles inside. The liquid falls from top to bottom, and the nozzles spray the liquid into a mist or raindrop shape. The chemical exhaust gas passes through from bottom to top and comes into close contact with the mist or raindrop liquid to carry out mass transfer, so that the harmful and soluble components in the chemical exhaust gas are absorbed.

[0003] Traditional spray towers recycle and reuse water resources during use. However, when filtering water resources, filter screens or filter cartridges are used. After a certain period of use, impurities will adhere to the filter screens or filter cartridges, which will affect the filtration effect and require frequent replacement, causing inconvenience.
