Description

Technical Field

[0002] With the rapid development of the electric power, electronics and electrical appliance industries, mica tape, as an important insulating material, has a growing market demand. Mica tape has been widely used in electrical equipment such as motors, transformers, cables, etc. due to its excellent electrical properties, heat resistance and mechanical properties. However, in the production process of mica tape, a certain amount of waste gas will be generated due to the use of adhesives, drying and other processes. These waste gases may contain volatile organic compounds, particulate matter and other harmful gases. If they are directly discharged into the environment, they will pollute the atmospheric environment and affect human health.

[0003] In order to reduce the pollution to the environment, waste gas treatment devices are usually used to treat waste gas. There are many types of waste gas treatment devices on the market, and most of them use the method of spraying liquid to treat waste gas. However, since this type of spraying operation is carried out in a corresponding closed space, it is not convenient to discharge impurities and clean the closed space after the subsequent reaction generates impurities, which will cause the accumulation, residue, deterioration of impurities, etc., affecting the subsequent treatment and use effect. In view of this, we proposed a waste gas treatment device for mica tape production. Utility Model Content
