Description

Technical Field

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

[0002] Cyclone spray tower, also known as cyclone scrubber or cyclone dust collector, is a common industrial waste gas treatment equipment. It is mainly used to remove particulate matter, dust, smoke and other pollutants generated in the industrial production process. The working principle of the cyclone spray tower is to use centrifugal force to separate the particulate matter in the dust-containing gas, and at the same time wash the particulate matter through the spray liquid to achieve the purpose of purifying the waste gas. The cyclone spray tower has the advantages of simple structure, high treatment efficiency and stable operation. It is widely used in waste gas treatment in various industrial fields, such as thermal power generation, steel, chemical industry, cement and other industries. In actual applications, cyclone spray towers often need to be used in conjunction with other waste gas treatment technologies (such as wet electrostatic precipitator, bag dust collector, etc.) to achieve better purification effects.

[0003] The cyclone spray tower is one of the equipments used in waste gas treatment. Although the traditional cyclone spray tower has the ability to treat waste gas, it still has some shortcomings. For example, it is difficult to recycle and reuse the spray liquid. Therefore, a large amount of water resources will be consumed during its use, which will not only increase the treatment cost, but also violate the concept of green environmental protection. In addition, its filtering structure is relatively fixed, and it is difficult to clean or maintain the filtering structure. Therefore, it is difficult to ensure the filtering effect of the filtering structure, which will affect the effect and efficiency of waste gas treatment. Therefore, a cyclone spray tower for waste gas treatment is proposed to address the above problems. Utility Model Content
