Description

Technical Field

[0001] The utility model relates to the technical field of waste gas spray towers, in particular to a cyclone spray tower. Background Art

[0002] The cyclone hybrid spray tower is a device used to treat industrial waste gas. Its main function is to adsorb harmful substances in the discharged waste gas, thereby purifying the waste gas and protecting the environment and human health. Waste gas purification equipment is widely used in the treatment of industrial waste gas in the chemical, metallurgical, electric power, petroleum, pharmaceutical and other industries.

[0003] The main purpose of the cyclone hybrid spray tower is to treat pollutants in exhaust gas, which often contains pollutants such as harmful gases, particulate matter and odorous substances. Direct discharge will have a serious impact on the surrounding environment and human health. The cyclone hybrid spray tower uses physical adsorption technology to adsorb pollutants in the exhaust gas so that it meets environmental emission standards. It plays a vital role in the treatment of industrial waste gas. It can reduce the impact of industrial waste gas on the environment and human health from the source, realize the resource utilization of waste gas, and promote sustainable development. With the improvement of environmental awareness and the continuous improvement of laws and regulations, although some advanced equipment adopts the trinity technology of decomposition, conversion and adsorption, there is still room for improvement overall; advanced cyclone hybrid spray towers usually require higher investment costs, which may be a constraint for some small or emerging manufacturers. The high cost of equipment may also affect the competitiveness of small and medium-sized enterprises in the industry;

[0004] At present, the spray tower used in my country includes a casing, which is provided with an air inlet and an air outlet. The casing includes a primary treatment structure, a secondary treatment structure and a cyclone treatment structure. The waste gas entering the air inlet is discharged from the air outlet after passing through the primary treatment structure, the secondary treatment structure and the cyclone treatment structure in turn. The primary treatment structure is used to perform initial adsorption of the waste gas, and the secondary treatment structure is used to perform secondary adsorption of the waste gas after initial adsorption. The casing also includes a circulation structure, which is used to circulate the spray liquid in the casing to the waste gas after initial adsorption and the waste gas after secondary adsorption respectively. The cyclone treatment structure is used to mix the waste gas after secondary adsorption with the spray liquid; however, the waste gas treatment capacity of the existing spray tower is low; the adsorption water washing section of the existing equipment is too short and the number of water washings is small, resulting in a small contact area and short time between the waste gas and the water flow in the water washing section. Therefore, it is not possible to achieve a higher standard of harmful waste gas purification. The existing equipment still has a large room for improvement in meeting the daily production and use of enterprises, especially in terms of waste gas purification and treatment capacity. Therefore, it is necessary to design a new cyclone spray tower to solve the above problems. Utility Model Content
