Bag filter housing is fixed. Its external perennial exposed to the elements, internal contamination of the process gas, the conditions are very harsh. Maintenance points inside and outside the box into two parts. (1) External Maintenance External maintenance mainly to check the paint, leaks, sealing bolts and the surrounding circumstances. For high temperature, high humidity gas, in order to prevent condensation and to ensure the security, there is generally outside rock wool, glass wool, polystyrene esters such insulation. After the insulation is wet rain, it will accelerate the corrosion of the box, so on the open spaces of the filter whenever it rains to give full attention. (2) Inside the inner case in a easy maintenance condensation, dust and gases dissolved after attachment may cause corrosion environment. They are susceptible to corrosion of steel parts welded portion between the plate and the angle between and install dust bag flower panel edge and so on. Therefore, the maintenance of the main interior of the enclosure is to be selected corrosion resistant coating, applied in a timely manner in soil corrosive or corroded parts. In general, due to purge gas mostly acidic. Therefore, the choice of acid-resistant epoxy paint more. (3) Slit slit general maintenance tank with a rubber mat, pad, asbestos pad, etc., to prevent gas leakage. With time, some seals will deteriorate, and damage fall off, resulting in increased air leakage. When servicing, we found that the above phenomenon to be taken seriously, or replacement of, or plugging, to avoid leakage. In conventional plugging materials, epoxy resins and leak-proof clay materials are preferred, such as the formation of holes due to erosion dust must repair welding.
