Influence of flue gas on dust bag
Dust bag dust is the main tool of bag type dust collector, which can isolate harmful gases, protect the environment and human health, but in industrial production, there are many factors that have influence on it, and the greatest effect is smoke, let's take a look at the effect of flue gas dust cloth bag:
(1) the high temperature of the flue gas. The bag filter is mainly used in the dust removal of industrial boilers, fluidized bed boilers, kilns and coal-fired utility boilers. The temperature of this kind of flue gas is often higher, and the temperature is about 100 to 300 C when the gas is passed into the dust collector. So the performance of ordinary chemical fibers at this temperature will be affected, so the filter material of the bag filter must be made of high temperature resistant fiber material.
(2) corrosion of acid gas. When the combustion of high sulphur coal or without flue gas desulfurization process, the sulfur oxides, nitrogen oxides concentration will be very high, in addition to the FT dust bag filter and other chemical synthetic fiber material will be eroded, so the dust bag will shorten the service life.
(3) the oxidation of the flue gas. Have a certain effect on the oxidation of flue gas dust bag, because the oxygen in the air for 21%, plus the flue gas temperature is very high, so the bag will suffer at work, if you want to avoid this situation, we must choose some antioxidant materials such as dust bag, dust bag made of P84 polyimide materials.
(4) the moisture in the flue gas. When working in a high temperature state, when the moisture content in the flue gas exceeds 25%, the dust will produce the phenomenon of easy sticking bag and blocking the bag. If the hydrolysis resistance of the material is not high, the hydrolysis will also damage the filter material.
Now, our country is in the rapid development of people's livelihood, to health, countries in the increasingly strengthen environmental protection efforts, dust bag produced to solve the problem of industrial pollution, hope that we can make reasonable use of the dust bag, so that we can have a healthy and clean tomorrow.
