Description

Technical Field

[0001] The utility model belongs to the technical field of filter materials, and particularly relates to a special polyphenylene sulfide filter material suitable for power plants. Background Technique

[0002] Emissions generated during the production process of power plants can affect the surrounding environment. When the emissions have too much impact on the surrounding environment, it will cause environmental deterioration. Therefore, various types of filter materials are used in the production process of power plants to treat emissions such as flue gas and wastewater, so as to reduce pollutant emissions.

[0003] Publication No. CN218392793U discloses a high-performance dust removal filter material for power plants. In view of an ultra-fine fiber polymer dust removal filter material disclosed in the prior art, when in use, the installation of the filter material needs to fix both sides separately, which is rather cumbersome and affects the disassembly and installation efficiency. Moreover, the anti-corrosion and wear-resistant performance of the filter material is poor, which is likely to shorten the service life of the filter material. By setting a convenient disassembly component, the quick disassembly and installation of the filter material body are realized, avoiding the cumbersome situation that both sides of the filter material body need to be fixed separately during installation, enabling both sides of the filter material body to be fixed simultaneously, improving the installation efficiency, and being quickly detachable, thus facilitating the disassembly and installation of the filter material body.

[0004] During the use of this filter material, since the gas in the power plant may contain particulate matters that are prone to generating static electricity and it has no good anti-static effect, it may lead to the occurrence of fires. At the same time, the particulate matters and fine dust in the flue gas of the power plant are relatively fine, requiring better filtration efficiency and effect, and at the same time requiring better wear-resistant characteristics, etc. Therefore, a special polyphenylene sulfide filter material suitable for power plants is proposed.
