P84 high temperature resistant dust bag and filter bag have the following three significant features:
1. Significant temperature resistance Long-term use temperature of 260 ° C, with space to deal with downtime and unexpected events.
2. Good chemical resistance has proved the value of P84 filter bag for acidic exhaust gas and alkaline dust in the waste incineration operation in the past ten years.
3． Low backwash pressure and high elasticity. The P84 characteristics are remarkable because of the fineness of the fiber itself. Because of the irregular fiber cross-section, the fiber surface area is increased to provide a lot of tiny pores to make the surface filtration effect better than deep filtration Dust only stays on the surface of the needle-punched filter felt and cannot penetrate into the filter felt. Therefore, the backwash pressure is small and the cake ejection efficiency is significantly improved. It has a fine particle collection efficiency and a small working pressure difference.
The superior performance of P84 high temperature resistant dust bag and filter bag:
Cost saving: low pressure drop makes cost reduction;
Filtration efficiency: suitable for strict environmental standards and temperature resistance (up to 260 ° C / 500 ° F);
Low failure rate;
Long working life
Excellent chemical stability (strong resistance to acid and alkali, can be used for PH2-12 occasions);
Suitable for a wide range.
Special cross-section of P84 high temperature resistant dust bag and filter bag:
The trilobal cross section is characteristic of the P84 fiber, which is a wealth compared to other round fibers because it increases the fiber surface area by 80%, which results in:
Unparalleled filtration efficiency;
Since no dust or fine stone chips penetrate the felt, there may be a low pressure drop;
Application fields of P84 high temperature dust-proof bag and filter bag:
The large pulse bag dust collector has good acid and alkali resistance and strong temperature resistance (260 degrees), which can be used in harsh working conditions; it is widely used in waste incineration, thermal power generation, steel, metallurgy, chemical industry, etc. .
