Acrylic needle felt dust bag

Acrylic needle felt dust bag is a key part of the operation of bag dust collector.Usually,the cylindrical filter bag is hung vertically in the dust collector.The fabric and design of the dust filter bag should strive for filtration,easy dust removal and effect.In pulse and air box pulse dust collectors,dust is attached to the outer surface of the dust bag.When the dust-laden gas passes through the dust collector,the dust is captured on the outer surface of the filter bag,and the clean gas enters the filter bag through the filter material.The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing,and it also helps to disperse and redistribute the dust cake.

Acrylic needle felt dust bag is a kind of dust bag.It is made of needle felt chemically called polyacrylonitrile.It is made of felt by needle punching method,and then treated to obtain acrylic medium temperature anti-hydrolysis needle filter felt.

Acrylic needle felt dust bag has an air permeability of 14m3/m2?min,instantaneous working temperature:160℃,normal working temperature 140℃,and the needle felt is reinforced with acrylic woven fabric as the base fabric.

The chemical name of acrylic needle felt filter bag is polyacrylonitrile,which is used as raw material to make felt by needle punching,and then treated to obtain acrylic medium-temperature anti-hydrolysis needle filter felt.The needle felt is reinforced with acrylic woven fabric as the base fabric.It has excellent chemical resistance and hydrolysis resistance,and is widely used in dust collection of flue gas such as garbage incineration,asphalt,spray dryer,coal mill,power plant,etc.

Features of acrylic needle felt dust bag:

1.Continuous working temperature is 130 degrees,and the instantaneous temperature does not exceed 140 degrees;

2.Good acid and alkali resistance,PH value is between 3-11;

3.Relative humidity is less than 30%,pay attention to oxidation.
