How to select most suitable dust collector filter bags?

Select suitable dust collector filter bags which are with best cost performance according to working condition

According to working temperature:

When temperature is less than 130 degree C, choose normal temperature dust filter bags, when temperature is 130-260 degree C, choose high temperature dust filter bags.

According to gas moisture:

Dust gas is divided into three states according to relative humidity.

Dry gas: relative humidity is below 30%

Normal gas: relative humidity is between 30%-80%

High humidity gas: relative humidity above 80%

When gas humidity is too high, shall use ptfe laminated and water repellent filter bags.

According to chemical properties of dust gas:

Acid, alkali, oxidant, organic solvents and other chemical components are contained in different of kinds of kiln flue gas and chemical waste gas. Therefore, shall select suitable dust collector filter bags which are with acid, alkali and oxidation resistance according to the chemical composition contained in the gas.

Select suitable dust filter bags according to special property of dust

According to wet ability and adhesiveness of dust:

If the dust is hygroscopic and has a strong adhesion, shall select dust filter bags which are treated with ptfe lamination/membrane and water proof or water repellent.

According to flammability and charging of dust: when some dusts are flammable, flame retardant dust filter bags should be selected. Antistatic dust filter bag is specially used for charged dust.

Select dust filter bag according to the dust cleaning mode of dust collector bag house

Shaking type dust collector bag house:

Shall select dust filter bags with thin, smooth and soft material which is conducive to the transmission of vibration waves.

Air reversed dust collector bag house:

Shall select dust filter bag with soft material which is with stable structure and good wear resistance.

Pulse jet bag filter: normally use round dust filter bag with support filter bag cage/frame. And the filter bag materials shall be thick, wear resistant and with strong tensile resistance.
