　　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.

　　And the grey water is discharged from the automatic overflow water seal at the bottom of the high-efficiency stable cyclone reverse mass transfer washing room to the circulation pool through alkaline water and sedimentation treatment, and alkaline wastewater recovery for use in the desulfurization and dust removal device. The clean water flows out from the drainage outlet at the bottom of the high-efficiency dehydration and dehazing room, gradually integrating and completing the entire process of smoke removal, desulfurization, denitrification, dust removal, dehydration, and dehazing.

　　(1) The boiler flue gas emissions range from 12000m3/h to 14000m3/h.

　　(2) After the boiler flue gas is exchanged in two stages through the economizer and heat pipe exchanger, the flue gas temperature is controlled between 140 ℃ and 170 ℃.

　　(3) Smoke and dust emission concentration

　　(4) Use a blowback valve to control the flue gas in the pipeline to ensure that the filter bag cleaning operation can be carried out without shutting down the boiler.
