　　Product Maintenance

　　Regularly check the operation of control valves, pulse valves, and timers.

　　The failure of the pulse valve rubber diaphragm is a common fault in bag filters, which directly affects the dust cleaning effect. This device belongs to the external filter type, with a skeleton inside the bag. It is necessary to check whether the parts that fix the filter bag are loose and whether the tension of the filter bag is appropriate. Is the support frame smooth to prevent wear and tear on the filter bag. Compressed air is used for dust removal. Therefore, it is required to remove oil mist and water droplets, and the oil-water separator must be cleaned regularly to prevent malfunction of the moving mechanism and blockage of the filter bag.

　　Whether the air volume and pressure and temperature at each testing point are consistent with the design.

　　The installation status of the 3 filter bags, whether there are any occurrences of bag dropping, loosening, wear, etc. after use, can be judged by visually observing the emissions of the chimney after operation.

　　4. Prevent condensation

　　During use, it is necessary to prevent the gas from cooling below the dew point in the bag chamber, especially when using a bag filter under negative pressure. Due to the frequent leakage of air into the outer shell, the gas temperature in the bag chamber is lower than the dew point, causing the filter bag to become damp. This results in dust not being loose but sticking to the filter bag, blocking the fabric holes and causing dust removal failure. This leads to excessive pressure drop in the dust collector, making it unable to continue operating, and some bags may become stuck and unable to remove dust.

　　To prevent condensation, it is necessary to maintain the temperature of the gas in the dust collector and its system at 25-35 ℃ above its dew point (such as the dew point temperature of 58 ℃ for kiln mill integrated machines, and the operating temperature should be above 90 ℃), in order to ensure the good use effect of the filter bag.

　　Characteristics and Disadvantages

　　The manufacturing cost of wet dust collectors is relatively low. But it is the most ideal way to remove dust generated by industries such as chemical, spray painting, glaze spraying, pigments, etc. that contain moisture, viscosity, and irritating odors. Because it can not only remove dust, but also use water to remove some odors. If it is a harmful gas (such as a small amount of sulfur dioxide, hydrochloric acid mist, etc.), an absorbent can be prepared in the washing solution to absorb it. Disadvantages:

　　The mud discharged from the wet dust collector needs to be treated, otherwise it will cause secondary pollution;

　　When purifying corrosive gases, chemical corrosiveness is transferred to the water, so the sewage system needs to be protected with anti-corrosion materials;

　　⑶ Not suitable for hydrophobic smoke and dust; For viscous smoke and dust that can easily cause blockages in pipelines, blades, etc;

　　Compared with dry dust collectors, it requires water consumption and is difficult to handle. In extremely cold areas, anti freezing measures should be taken.
