Selecting the filter bag precautions

With the continuous development of modern industry, the state has a variety of flue gas emissions in the solid waste standards have strict requirements and norms, many factories and enterprises in order to make the flue gas emissions to meet the standards on the need for emissions of flue gas Treatment, It is a common approach to get rid of solid waste contaminants by the bag of filter bag.

Bag is an indispensable parts to Bag filter, selecting the appropriate material, size and model to the entire dust collector dust removal effect is essential. If choose inappropriate materials not only cannot achieve dust, reduce the role of solid waste pollution, but also cause investment losses, resources waste.

What should pay attention to when choose bag? This requires a general understanding of several aspects.
First, clarify the nature of the flue gas to be discharged, such as gas temperature, moisture, acidity, corrosivity, flammability, explosive and gas containing solid waste concentration and so on. Although there are many kinds of filter bag material, but their temperature is not the same, and some exclude the gas temperature is high, if you choose the bag material is not high temperature, it will be burned. Corresponding to the flue gas moisture, pH, corrosive, flammable, explosive, etc. is also true, in the selection of the bag before the specification model, to clarify these issues, select the appropriate material in order to achieve the intended Emission standards and effects. At the same time, the emission of solid waste containing solid waste concentration is also important, if the concentration is too large need to consider before entering the bag filter with cyclone dust removal device or other measures to do pretreatment.

Second, dealing with some explosive, flammable properties of flue gas dust, when the outside temperature is relatively bad, need do process insulation treatment the entire dust collector to prevent the outside temperature is too low and influence the dust chamber temperature, resulting in the overall temperature of the chamber down, eventually leading to condensation of dust and dewed smoke bag, and then need to replace the filter bag to deal with or more serious consequences.
Third, need to clear the amount of smoke bag to deal with, and the dust removal equipment to allow the ground and other factors. There are many types of dust collector, different types have corresponding design requirements, the length of bag dust removal also has the corresponding requirements. Choosing appropriate types of filter bag and the corresponding type of dust, not only meet the processing requirements, but also save the ground and investment.

Fourth, the choice of filter bag also has an impact on the follow-up equipment configuration. Dust catcher not only removal dust, but also can be used as a dust collector to collect the desired products, such as the preparation of pulverized coal, this process requires to collect a large number of coal transport storage, dust collector hopper exports need to configure the spiral Conveyor and so on.
In short, a reasonable bag material, size and selection for the overall dust or dust collection system is very important, only a comprehensive consideration lots of factors to achieve optimal allocation of resources, improve material utilization, and ultimately higher social benefits and investment objectives.
