P84 High Temperature Resistant Needle—punched Felt Bag

　　P84 High Temperature Resistant Needle—punched Felt Bag

　　It has remarkable temperature resistance and good chemical resistance. It has certain advantages in filtration of acid waste gas and alkaline dust. It has low backwash pressure and high sludge cake efficiency. It is used in asphalt plants, cement plants, waste incinerators, liquid bed boilers and coal—fired boilers.

　　The filter bag is the key component to determine the dust removal efficiency and working temperature of the bag dust collector, and the cost of replacing the filter bag is the main maintenance cost of the bag dust collector. Therefore, the working life of the filter bag is related to the operation state and cost of the dust collector, so it is particularly important to select the appropriate filter material and design the reasonable structure.

　　The selection of filter material should be considered according to the temperature, humidity and chemical characteristics of the gas, the size, weight, shape, ponderability of particles, dust concentration, filtration speed, ash cleaning mode, emission concentration and the working system of bag dust collector. In general, the pulse spray bag filter uses needle felt, the chamber back blowing bag dust collector or the mechanical vibration bag filter selects the woven cloth.
