High-temperature-resistant filtering material for electric power and asphalt stirring, and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant filtering material for electric power and asphalt stirring, wherein the high-temperature-resistant filtering material sequentially comprises a first fiber layer, a high-precision filtering layer, and a second fiber layer. The invention further provides a preparation method of the high-temperature-resistant filtering material. According to the present invention, the high-temperature-resistant filtering material can intercept dust, has high filtering precision and high air permeability, can reduce power consumption and cleaning times, and canachieve energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of industrial dust removal. It relates to a filter material, in particular to a high-temperature-resistant filter material used in electric power and asphalt mixing. Background technique [0002] my country's coal-based primary energy structure determines that thermal power generation is the main power production mode in my country, and thermal power generation accounts for more than 70% of the country's total power production. Primary means of electricity production. Smoke and dust emitted by thermal power plants is the main source of air pollution in my country, and controlling smoke and dust emissions from thermal power plants is one of the important measures to protect the ecological environment. [0003] Thermal power enterprises originally implemented the 50mg / m2 standard stipulated in the "Emission Standard of Air Pollutants for Thermal Power Plants" (GB13223-2003) 3 emission limits. In July 2011, ...

Problems solved by technology

[0006] In recent years, the generation of smog weather has made the masses pay more and more attention to the air pollution problem, and the new environmental protection law has become increasingly strict. The ordinary needle felt filter material can no longer fully meet the increasingly stringent industrial exhaust emission standards.

[0007] At present, the most commonly used film-coated filter media with higher filtration accuracy has short service life (the membrane-coated filter material often has de-filming in actual use, which leads to the failure of the film-coated filter material), high wind resistance (film-coated filter media The material mainly relies on the micropores of the membrane to intercept dust, the higher the filtration accuracy, the smaller the micropores, and the greater the resistance) and other defects
