Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to waste gas spray tower equipment for waste gas treatment. Background Art

[0002] Exhaust gas treatment, also known as exhaust gas purification or waste gas management, primarily refers to the management of industrial waste gases generated in industrial sites (such as factories and workshops). These waste gases may include dust particles, smoke, odorous gases, and toxic and hazardous gases. The purpose of exhaust gas treatment is to pre-treat waste gases before they are discharged to meet national emission standards.

[0003] In some scenarios, spray towers are used to remove harmful substances from exhaust gas. For example, the existing exhaust gas spray tower, patented CN203155054U, features at least five layers of absorbers, each separated by Raschig rings. A two-stage spray system ensures that exhaust gas flowing upward from the bottom of the absorber fully contacts the absorbent sprayed from the top, resulting in effective absorption. By varying the absorbent, this system can also treat exhaust gas from phenol, styrene, butyl acrylate, and methyl methacrylate, broadening its application.

[0004] However, since the ratio of water solvent in this device is difficult to guarantee, the purification efficiency is poor and the reliability is poor. Utility Model Content
