Problems solved by technology

[0002] In some of the factories, the exhaust gas will have a certain temperature when it is discharged, which will cause great damage to the needle-punched filter material, and then affect the filtering effect and efficiency of the exhaust gas. Therefore, it is necessary to propose an anti- Needle-punched filter material with strong exhaust gas at medium temperature

Abstract

The invention discloses a needle-punched filter material with high medium-temperature waste gas resistance. The filter material comprises a supporting layer, a first absorbing layer is fixedly connected with the lower surface of the supporting layer, a filtering layer is fixedly connected with the side wall of the side, away from the supporting layer, of the first absorbing layer, and a second absorbing layer is fixedly connected with the side wall of the side, away from the first absorbing layer, of the filtering layer. The filter material has the advantages that when medium-temperature wastegas is filtered, the medium-temperature waste gas is blocked through a blocking layer, so that the medium-temperature waste gas does not directly contact the filter material, large particular dust inthe waste gas is blocked, medium-size particles in the waste gas are absorbed by the second absorbing layer, the waste gas is filtered by the filtering layer, micro particles in the waste gas are absorbed by the first absorbing layer, and the waste gas is discharged. By means of the filter material, the influence on the filtering effect and efficiency of the waste gas caused by larger damage on the needle-punched filter material by the medium-temperature waste gas is prevented.

Description

technical field [0001] The invention relates to an acupuncture filter material, in particular to an acupuncture filter material with strong resistance to medium-temperature exhaust gas, and belongs to the technical field of acupuncture filter materials. Background technique [0002] In some of the factories, the exhaust gas will have a certain temperature when it is discharged, which will cause great damage to the needle-punched filter material, and then affect the filtering effect and efficiency of the exhaust gas. Therefore, it is necessary to propose an anti- Needle-punched filter material with strong exhaust gas at medium temperature. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a needle-punched filter material with strong resistance to medium-temperature exhaust gas. [0004] In order to solve the problems of the technologies described above, the present invention provid...
