1. Hardening and shrinkage due to abnormal high temperature;2. Due to contact reaction with acid, alkali or solvent vapor;3. Reacts with water;4. The bag of the dust collector is blocked, the resistance will increase after the blockage occurs, and the cleaning interval will be shortened;These factor

The main reasons for the damage of dust collector bags are generally as follows:1. Dust mediumThe choice of the bag cloth of the dust collector depends on the dust properties of the dust, and it is necessary to consider whether the dust contains acid, alkali or strong corrosive substances. Select th

The membrane dust filter bag has become an indispensable new material for dust and material filtration and collection, as well as precision filtration. The dust collection efficiency of the dust filter bag is higher and the service life is longer. The advantages are:1. High efficiency of unfinished

1. Water mist cooling In order to avoid the sudden rise of flue gas temperature due to air preheater jamming or other flue gas combustion failures, which affects the service life of filter bags, measures should be taken to cool down and spray water mist before the inlet of the dust collector. This m

Before the first use, and within 48 hours before being put into use after a long-term shutdown, it is necessary to carry out pre-coating treatment. The so-called pre-coating is to add a filter aid to the dust-facing surface of the dust filter bag to make it more perfect for dust removal and purifica

Because the long-term operating temperature of polyester cloth bags under air drying conditions should be less than 120℃, and in flue gas with higher moisture, its long-term working temperature can only be reduced to 60~100℃; Metas cloth bags are temperature-resistant and chemical-resistant The perf
