Polyester dust removal cloth bag

polyester dust removal bag

polyester needle felt dust removal bag 1-2.5d polyester fine denier yarn is woven with < span style = "" > good strength

, low stretch yarn to strengthen the base cloth, which is made by needle reinforcement and post-treatment process; In addition to ordinary felt filter cloth, the product has high porosity, good air permeability and good acid resistance. In addition to the characteristics of moderate alkalinity, it also has very good advantages. Therefore, it is a variety of felt filter materials; The weight ranges from 350g / m2 to 800g / m2 and the thickness ranges from 1mm to 4mm, which can be produced by Zhixin environmental protection manufacturers; Post treatment methods include calendering, singeing, heat setting, impregnation drying, coating, etc., with stable size, easy ash removal and long service life. The surface smoothness of filter material has a great influence on the dynamic running resistance of filter material. The initial resistance of the filter material depends on the ventilation of the filter material itself, and the resistance in operation is many times greater than the initial resistance

use the same air flow with the same pressure and air volume for dust

removal

when the cloth bag vacuum cleaner selects the fabric with large ventilation as the filter bag, the dust removal

effect is better than that of the fabric with small ventilation. Therefore, when the filter material reaches high filtration accuracy, how to improve the ventilation and surface smoothness of the filter material, reduce dust adhesion and reduce operation resistance is the first topic that the filter material manufacturer should study

equipment

the surface of needle punched filter material is resinified and smooth, and its air permeability is 50% higher than that of ordinary calendered filter material, and the surface smoothness is smoother than that of pressed and smooth finishing

selection criteria for polyester dust bag parameters:

1. Determine the filter area of the dust bag:

the dust removal efficiency of the dust collector is closely related to the properties of the dust bag, filtration speed, gas dust concentration and continuous operation time. These factors are interrelated

2. Determine the specification of the dust bag:

the specification of the dust bag is related to the inlet speed of the gas entering the dust bag. When the dusty gas enters each dust bag, if the inlet speed is too fast, on the one hand, it will accelerate the secondary flight of dust removal; on the other hand, the friction of dust will aggravate the wear of dust bag, so it can not be too large. Of course, the parameters of dust collector accessories such as fan air pressure and air volume supporting bag dust removal equipment will also directly affect the dust removal effect, which should also be considered together in the process of design and use. With the deepening of the theoretical and technical research of bag dust removal equipment, such as design parameters, further study of filtration mechanism, filter material performance, equipment structure and dust removal methods, bag dust removal equipment will play a role in the production of paper industry and environmental protection
