Description

Technical Field

[0001] The utility model relates to the technical field of heavy ion microporous membrane production equipment, in particular to an industrial waste gas purification device based on heavy ion microporous membrane. Background Art

[0002] As a new type of filter material, heavy ion microporous membrane is the only high-precision filter membrane with true pore size and excellent performance. Heavy ion microporous membrane has high separation selectivity and can absolutely intercept any particles larger than the pore size. The separation efficiency can reach 100%. Polyester membrane material is used, which does not absorb substances in the filtrate, and can prevent the effective ingredients in the filtrate from being absorbed and lost. There will not be any migratable substances into the filtrate, so it will not pollute the filtrate. Nuclear microporous membrane has been widely used in electronics, chemical industry, petroleum, medicine, health, food, brewing, biology, environment, analysis and detection and other fields. During the production process of heavy ion microporous membranes, a large amount of industrial waste gas will be generated, causing the air pollution to continue to increase, seriously endangering human health, especially the particulate pollutants, sulfur compounds, nitrogen oxides, etc. in the waste gas will seriously affect the human respiratory system, blood system and central nervous system, etc., and in severe cases will cause lung disease, cancer, etc. Industrial waste gas contains not only dust but also harmful substances such as sulfur dioxide and hydrogen sulfide. These waste gases are directly discharged into the atmosphere, which will cause serious pollution to the environment. In order to solve this problem, an industrial waste gas purification device based on heavy ion microporous membrane is proposed.

[0003] In the publication number: CN209501329U, an industrial waste gas purification device includes a base, a spray frame is fixedly connected to the top of the base, and an adsorption frame is provided on the top plate of the spray frame. The utility model relates to the technical field of waste gas treatment. The industrial waste gas purification device achieves the purpose of treating industrial waste gas, reducing the presence of pollutants, passing the industrial waste gas into an alkaline solution for filtration, and then spraying. Because the spray port rotates, the atomization area is increased, and the waste gas is treated again, further reducing the presence of pollutants, reducing environmental pollution, and better protecting the environment. The treated industrial waste gas is treated again, reducing pollution emissions, and improving the purpose of waste gas purification.

[0004] In order to solve the problem that the existing industrial waste gas purification devices often have poor purification effects, the existing technology uses a filter screen, a drying plate and an activated carbon adsorption net to cooperate with each other to treat the treated industrial waste gas again. However, in actual use, the filter screen, the drying plate and the activated carbon adsorption net are all fixedly connected, which is easy to cause blockage and difficult to clean after long-term use, thereby making cleaning difficult and reducing the waste gas purification effect.
