Bag type dust collector box maintenance

The box of the bag filter is fixed. Its external perennial wind and rain, Internal by the treatment of gas pollution, the conditions are quite harsh. The cabinet maintenance is divided into two parts: inside and outside.
1. External maintenance
External maintenance is mainly to check the paint, leakage, bolts and surrounding sealing. For high temperature, high humidity gas, in order to prevent condensation and ensure safety, generally in the external rock wool, glass wool, polystyrene and other insulation layer. After the insulation layer is wet by rain, it will accelerate the corrosion of the box body. Therefore, the dust collector placed in the open air should be fully paid attention to whenever it rains.

2. Internal maintenance
The inside of the box is in an environment that is prone to condensation, dust and gas dissolution may cause corrosion. The welding parts between steel plates and between steel plates and angle steel plates, and the edges of flower plates where filter bags are installed are all easily corroded parts. Therefore, the maintenance of the interior of the box is mainly to pay attention to the selection of corrosion-resistant coatings, timely coating in the easily corroded or corroded parts. In general, because the purification gas is more acidic, so the use of epoxy resin type of acid-resistant coatings more.

3. Gap repair
The box gap is generally padded with rubber, rubber pad, asbestos pad, etc. to prevent gas leakage. With the extension of time, some sealing gasket will aging deterioration, damage and fall off, resulting in increased air leakage. In the maintenance, found that the above phenomenon should be taken seriously, or replacement, or plugging, to avoid air leakage. In the existing plugging materials, epoxy resin and leak-proof glue are better materials, such as holes formed by dust erosion must be welded.
