Industrial Filter Bags for Efficient Filtration Systems

what is filter bags？

    Filter bags are also commonly referred to as dust collector filter bags、dust filter bag、baghouse filter bags，As the filter element, the filter bag is a key part of the filtration process, filter bag quality determine the filter efficiency for the end user. our own high technology filter cloth,with patent structure ring mouth and manfactured by the professional production equipment can meet the application of various fields.

Two factors effect the choice of filter bags:

1、Temperature: As the main component of dust collector, it is very important whether selected filter bag adapt to the flue gas temperature . Such as, the heat resistance of filter material exceeds the flue gas temperature too much, which will cause the waste of high temperature filter material as well as big investment in equipment. If it is lower than that of flue gas, it is possible to cause the burning of bag.

So how to select the filter material according to the flue gas temperature? It can be divided into the following according to the temperature:

normal temperature filter material: below 130 degrees Celsius,

medium temperature filter material 130~180, 

high temperature filter material 180~280.

2、flue gas composition: It includes the content of dust, specific gravity, particle size, viscosity or not, the water content in the flue gas and other parameters. All of these decide the way of cleaning, filter bag material treatment,filtration velocity. Usually, if the dust is dense, sticky and light, we usually choose pulse bag house and pulse bag filter. In addition, the filtration velocity is control more than 1.2m /min, sometimes 1m /min.  As well as, the Filter material treatment is generally membrane, water and oil repellent, anti - static, oriented anti adhesive treatment.

Dust Separation Procedure

Different dust separation procedures require different weights and air permeability values for filter media.

Rules:

- The more effective the cleaning process, the more compact and heavier the filter medium can be.

- The higher the emission control standards, the heavier the filter medium should be.

Tops：If these factors are well considered in advance, running cost like electricity for the fan or pressured-air for the cleaning pulses can be saved later on in a great amount.
