High Temperature Punched Needle Felt Aramid Dust Collector Bag
Product Description
Compared with ordinary filter materials, Nomex filter bags also have the following advantages:
1. Excellent high temperature resistance: it can work continuously at a temperature of 204℃, and the instantaneous working temperature can reach 240℃;
2. High dimensional stability: only 1% expansion rate at 230℃ high temperature, with high temperature stability;
3. Fire and flame retardant performance: it starts to decompose and carbonize at 400°C, the limiting oxygen index (LOI) is 30, and it is neither spontaneous nor combustion-supporting;
4. Good chemical corrosion resistance: acid and alkali resistance and not easy to corrode.

How to install the nomex aramid dust collector filter bags?
1) New technology and old nomex dust filter bag in steel industry should not be mixed to avoid the difference in damage time from affecting the normal operation of the dust removal equipment.
2) The aging of high temperature industrial dust bag filter. Mainly due to the following reasons, it is necessary to investigate the cause, take elimination measures and replace the dust filter bag.
①It hardens and shrinks due to abnormal high temperature;
②Reacts due to contact with acid, alkali or organic solvent vapor;
③Reacts with moisture.
3) The non woven industrial filter cloth should not be hung too loosely or tightly. Too loose and easy to accumulate dust, and too tight to be easily damaged.
4) After replacing the dust collector filter sleeve, blow it with compressed air first, and then check for any holes. After the holes are repaired, they will be kept for replacement. If the cloth bag is stuck with dust, wash it with water, and leave it to be replaced after it has dried.
5) The clogging of the dust filter bags. When the cloth filter bag is clogged, the resistance increases, which can be reflected by the increase in the reading of the differential pressure gauge. The clogging of the cloth bag is the main reason for the phenomenon of cloth bag wear, perforation, falling off and so on. For the cause of the clogging of the dust bag, check and repair according to the following table. Generally, the following measures are taken:
①Temporarily strengthen dust removal to eliminate the clogging of the cloth bag;
②Partially or completely replace the cloth dust collection filter bag with snap ring;
③Adjust the installation and operating conditions.
Application field:
Flue gas treatment and dust removal systems in ironworks, steelworks, ferroalloy plants, refractory plants, foundries, power plants, etc.
Waste incinerators, coal-fired boilers, fluidized bed boilers and other flue gas filtration.
Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites.
Smelting flue gas filtration of aluminum electrolysis, lead, tin, zinc, copper and other rare metals, recovery of fine materials, separation of liquid and solid.
Liquid-solid separation and fine material recovery in the fields of chemicals, coke, carbon black, dyes, pharmaceuticals, plastics, etc.
Dust treatment and purification collection in mining, grain processing, flour, electronics industry, wood processing, etc.
The High efficiency nomex /aramid Dust Filter Bag in Steel Industry packaging:
Different types of bag filter cloth sock sleeves must be individually packaged. In general, it is wrapped in plastic bags for water proof, then put in a carton. stainless steel snap band Filter bag with the diameter of cell plate 135mm must be neat and regular packing, with the ring of the filter bag(whatever stainless steel or carbon material) to avoid ring flat compression deformation. For the requirement to keep the shape of filter bag, it must fill padding for filter bag inside. Any other packing ways also be accepted up to you.
