Anti-static multifunctional composite punched felt

Abstract

The invention relates to the technical field of a punched felt, in particular to an anti-static multifunctional composite punched felt. The anti-static multifunctional composite punched felt comprisesa base cloth layer, wherein a first composite punched felt layer is arranged at the upper side of the base cloth layer; a second composite punched felt layer is arranged at the lower side of the basecloth layer; a first reinforcing layer is arranged at the upper side of the first composite punched felt layer; a second reinforcing layer is arranged at the lower side of the second composite punched felt layer; a first protection layer is arranged at the upper side of the first reinforcing layer; a second protection layer is arranged at the lower side of the second reinforcing layer. The anti-static multifunctional composite punched felt has the following beneficial effects that through the arrangement of a first anti-static layer and a second anti-static layer, the whole anti-static effectof the whole punched felt is better; particle dust cannot be sucked, so that the particle dust blocks the punched felt; the dust filtering effect is effectively improved; wide popularization and application values are realized; the base cloth layer uses an arc-shaped ring and weft surrounding arrangement mode; the structure intensity of the whole base cloth layer can be effectively improved; theservice life of the whole base cloth layer can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of needle-punched felt, in particular to an antistatic multifunctional composite needle-punched felt. Background technique [0002] With the development of industrial society, people's awareness of environmental protection is gradually increasing, and the treatment methods for various waste liquids, waste gases and solid waste residues produced by industry are also being continuously optimized. Recently, PM2.5 The emergence has aroused everyone's attention. It mainly comes from various exhaust gases in life or production. In order to reduce the content of PM2.5 in the air and improve air quality, it is necessary to treat various exhaust gases, especially industrial exhaust gases. [0003] At present, the treatment of industrial waste gas mainly adopts needle-punched felt filtration method. In the iron and steel, metallurgy, chemical, pharmaceutical and other industries, the flue gas temperature is high and t...

AI Technical Summary

Problems solved by technology

[0003] At present, the treatment of industrial waste gas mainly adopts needle-punched felt filtration method. In the iron and steel, metallurgy, chemical, pharmaceutical and other industries, the flue gas temperature is high and the corrosion is strong. The destruction of the filter material shortens the service life of the filter needle felt and increases the production cost of the enterprise; and the antistatic ability of the traditional needle felt is poor
