Dusting Bags

Overview

The dusting bag, also called filter bag, is the key element that determines the dust removal efficiency and working temperature of the bag type dust collector, and the cost of replacing the filter bags is the main maintenance cost of the bag type dust collector. Therefore, the working life of the dusting bag is related to the operating status and cost of the dust collector, so it is particularly important to choose the appropriate filter material and a reasonably designed structure.

The selection of filter materials should be based on the temperature, humidity and chemical characteristics of the flue gas, the size, weight, shape, abrasiveness of the particles, and the dust concentration, filtration speed, dust cleaning method, emission concentration and the working system of the dust collector and other factors. Under normal circumstances, needle felt dusting bag is used for pulsed air blowing bag type dust collectors, and woven fabric dusting bag is used for chamber reverse blowing dust collector or mechanical vibrating dust collector.

Our company specializes in the production of 208 needle felt dusting bag, 729 needle felt  dusting bag, polyester needle felt dusting bag, water-proof, oil-proof and anti-static needle felt dusting bag, acrylic needle felt dusting bag, glass fiber needle felt dusting bag, FMS high temperature needle felt dusting bag, Metas needle felt dusting bag, Nomex high temperature needle felt dusting bag, Huate high temperature needle felt dusting bag, PPS, P84 high temperature needle felt dusting bags etc.. We have special filter clothes, such as aramid, PTFE, PVDF, etc., for high temperature applications.

Features and Advantages

For the filter cloth, it is not only the wear and tear of the material itself that affects its service life, but more importantly, the corrosion of the filter cloth by the working substance, therefore, the requirements for the industrial filter cloth are very high. 

Our filter bag cloth has the following features and advantages: 

● The capture effect after the solid is good and the service life is long;

● The filtration speed is fast, the blockage is less, and the filtration speed is stable;

● The filter residue has good peelability, no expansion and contraction, and good dimensional stability.

● Approach to zero emission, can meet the most stringent environmental standards;

● Good ash cleaning, can provide higher ventilation, or can reduce the pressure difference;

● The extension of the life of the filter bag and the reduction of the number of cleaning times reduce the maintenance cost of the equipment;

● Higher air-to-cloth ratio, smaller dust collector can be designed, and energy consumption is reduced when the differential pressure is reduced;

Application
