How high temperature can polyester filter bag withstand in general use?
Polyester filter bag is a kind of hard and soft fiber structure, the substrate strength is high, the mechanical strength is sufficient, the dust removal effect is good, the cost is low, the ash strength is low, the stable pressure loss is low. Long time use can prolong the life of polyester filter bag. Polyester filter bag has the characteristics of high air permeability, low resistance, high filtration efficiency, high energy absorption and high dust.
Polyester filter bag has the advantages of high porosity, good air permeability, high dust removal efficiency and long service life of ordinary felt filter cloth. Polyester filter bag high temperature resistance, high temperature resistance 150℃, acid and alkali resistance, excellent wear resistance. Polyester filter bag is a commonly used felt filter material.
Polyester filter bag can continuously work at 90℃ at 80℃ and instantaneously at 90℃. Polyester filter bag size stability, high strength, low elongation. In addition, polyester filter bag surface is smooth, easy to dust, operation resistance is small, comprehensive chemical resistance is good.
Polyester filter bag has low shrinkage rate, good filtration performance, corrosion resistance, stable size, can be used at high temperature for a long time, not exceeding 260℃ and acid-base environment, scope of application and use restrictions This filter bag product is suitable for gas-solid flow separation, high dust removal efficiency, low emission concentration, low dust ratio. Polyester filter bags are widely used. It can meet the requirements of internal and external protection and environmental protection.
Damage and wear of polyester filter bags are always an important part of the maintenance cost of filter bags. Therefore, polyester filter bag should pay attention to adjust the dust collector exhaust. When the flow is large, the automatic flow control system should be added to ensure that the dust collector runs under the stable gas volume. The uneven air inlet is easy to cause the local impact of the bag body, resulting in damage to the bag perforation. At this time, the air intake should be installed on the ventilation pipe, otherwise, need to replace wear-resistant polyester filter bag.
