Description

Technical Field

[0001] The utility model relates to the technical field of tail gas absorption equipment, in particular to a multi-stage spray tail gas absorption equipment. Background Art

[0002] Multi-stage spray tail gas absorption equipment; In the treatment of tail gas generated in the catalyst production process, a new tail gas multi-stage absorption technology has been developed through a thorough study of physical absorption and chemical absorption. The core of this technology is to extend the contact time between tail gas and spray liquid, thereby improving the absorption effect. Some technologies use a two-stage series multi-stage spray form of water washing plus alkaline washing to recover and purify gases such as sulfur dioxide. This method ensures the demisting effect and solves the problem of difficult maintenance of screen film by setting a cyclone plate demisting layer and an external wire mesh demisting device. The existing tail gas absorption tower has some shortcomings in treating industrial tail gas, such as the tail gas rising rate is too fast, and it cannot fully react with the alkaline liquid, resulting in incomplete tail gas treatment. In order to solve this problem, a multi-stage exhaust absorption tower was developed to improve the exhaust gas treatment efficiency and environmental protection effect. The spray cyclone plate exhaust gas purification tower is a technologically advanced wet dust removal equipment, especially in boiler dust removal and desulfurization and spray paint mist removal. It has good purification effect and low gas humidity content. In response to the needs of high-concentration exhaust gas treatment, an integrated multi-stage spray device was developed. The device has application value in the fields of mechanical engineering, chemical engineering, fluid mechanics and environmental engineering technology.

[0003] Most of the existing spray devices are traditional single-stage spray devices. Today's industrial exhaust emission standards are becoming more and more stringent. Single-stage spray absorption equipment can no longer meet the needs of exhaust treatment with certain high pollution loads or complex components, and it needs to deal with a variety of different exhaust gases and has poor adaptability. Therefore, we propose a multi-stage spray exhaust absorption equipment to solve this problem. Utility Model Content
