[0002] Waste gas spraying is a waste gas treatment technology, which is mainly used to treat waste gas generated in industrial production processes. It sprays the waste gas into liquid and uses the dissolution, absorption and chemical reaction of the liquid to remove harmful substances in the waste gas or convert them into harmless substances, so as to achieve the purpose of purifying the waste gas.

[0003] Waste gas treatment is carried out by spraying. When the existing spray device is in use, the waste gas is injected into the spray device through a pipe and discharged after spraying. The waste gas stays in the spray device for a limited time, so the contact time between the spray liquid and the waste gas is limited, resulting in incomplete treatment of harmful substances in the waste gas. Therefore, a device is urgently needed to solve the above problem. Utility Model Content
