Two factors effect the choice of filter bags

N01
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.
N02
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.

Application

PTFE filter bags are widely used to purify industrial dust with high temperature, high humidity and high viscosity, or industrial dust containing acidic and corrosive chemical gases. PTFE filter bag has a very important use in high-temperature flue gas filtration industry, with broad application prospects, mainly for the following aspects:

(1) Garbage incinerator, etc. It can purify flue gas with high humidity, high temperature, and high water content, strong chemical corrosively and high viscosity dust. The treatment of PTFE filter bags, especially the treatment of waste medical supplies and household garbage, can solve the problems of high-temperature combustion bags, high viscosity dust paste bags, and chemical gas corrosion bags and so on.

(2) Purification of industrial smoke and dust in power plant boilers burning high sulfur coal with acid, alkali and corrosive chemical gases; PTFE filter bag mainly has the advantages of non-sticking bag, easy dust removal, small running resistance of equipment, long service life, etc.

(3) Flue Gas Purification of Blast Furnace Gas in Iron and Steel Smelter. PTFE filter bag is mainly used to solve the corrosion problem caused by chemical gases such as high temperature, high humidity, paste bags below dew point and high-temperature sulfur.
