Glass fiber high temperature filter bag conditions

Glass fiber high temperature filter bag adopts glass fiber filter cloth specially woven and surface treated glass fiber fabric, so it is ideal for high temperature, medium temperature, low temperature and high humidity filter material.

Glass fiber high temperature filter bag is used in copper smelting flue gas acid purification process of a equipment, it is working under high temperature conditions of 200 to 300℃, and by acid smoke corrosion, therefore, the filter bag material problem will directly affect the normal production of sulfuric acid.

Glass fiber high temperature filter bag is made of alkali free glass fiber 80N 82 yarn as the base material, impregnated by graphite polytetrafluoron treatment solution and interwoven. The fabric structure is 5/2 weft satin weft double tubular structure.

The requirements for the use conditions and technical indicators of glass fiber high temperature filter bags are:

1. Conditions of use:

Operating temperature 200 to 300QC

The filtration speed is less than 1 m/min

Operating pressure differential 400 to 600 mm water column

Blowback air pressure 4 to 6 kg

2. Smoke composition:

Dust size below 5 microns

Population dust content 100 to 500 mg/m 3

50: Content 3~5%

50: Content 0. 1-0.5%

Monomer sulfur content 1000 mg/m "Fluorine content 04-60 mg/m"

3 Technical specifications:

Service life of more than three months

Filtration efficiency>95%(population dust content is 10.

When the outlet contains less than 5 mg/m of dust ")

Glass fiber high temperature filter bag is a conventional industrial filter cloth, widely used in valuable dust purification, environmental recovery, industrial dust removal plays a great role.
