P84 high temperature needle felt

P84 high temperature needle felt

P84 high temperature needle felt is obtained by needle punching of polyimide fiber, and its characteristics are notable due to its own fiber fineness.P84 high temperature resistant dust-removing cloth bag fiber is also known as polyimide, and its basic chemical composition is mainly composed of aromatic units. P84 filter media has high temperature resistance, good chemical resistance, and has a very significant effect on dusty gases with acid and alkali properties. It is widely used for flue gas purification in waste incineration, thermal power generation, iron and steel, metallurgy and other industries.

 

Features and characteristics of P84 high temperature resistant dust-removing cloth bag fiber filter material:

  1. The fiber section of the P84 high temperature resistant dust-removing bag is an irregular trilobe cross section. This special cross section increases the surface area of the P84 high temperature resistant dust-removing bag fiber, so that it can effectively trap tiny particles and is easy to clean
  2. It has superior chemical properties and can resist corrosion
  3. High dust collection accuracy
  4. P84 high temperature resistant dust removal cloth bag fiber is resistant to high temperature, can operate continuously at a temperature of 260 ℃, and can withstand an instantaneous temperature of 280 ℃
  5. The pressure loss of the bag filter adopting P84 high temperature resistant dust removal cloth bag as the filter material, the pressure loss changes steadily, which greatly saves the energy consumption of the induced draft fan and the ventilator, and reduces the operation steps and operating costs
  6. It has a long service life and can be used for more than four years under normal use conditions, which greatly extends the bag changing cycle and reduces maintenance costs
  7. It has good filtering performance and good air permeability

 

It is worth noting that although the P84 high temperature resistant dust removal cloth bag filter material has high temperature resistance, the use temperature of the P84 high temperature resistant dust removal cloth bag is inversely proportional to the acid concentration in the dust-containing flue gas. The higher the acid concentration, the higher the P84 resistance The lower the use temperature of high temperature dust removal cloth bags, the lower the acid concentration, the higher the use temperature of P84 high temperature resistant dust removal cloth bags.
