Smelter various production processes using the most efficient dust removal device is the pulse bag filter, if timely and effective solution to run the smelter dust fault, not only to ensure continuity of production, but also to extend the life of the pulse bag filter , manufacturer of filter has a positive meaning. China Science and Technology Park on the following Common symptoms smelter dust treatment method and look at detailed introduction: First, reduce the amount of smelter dust suction, suction outlet can not effectively trap dust causes of failure and treatment methods: 1, duct blockage damper shift processing method: Clean air hose, fixed throttle. 2, ESP, duct leakage confined strictly local approach: Check the filter and the sealing of the duct. 3, filter design air volume is too small to handle: Replace the filter. 4, the fan does not match Solution: Replace the fan. 5, the bag-fouling treatment methods: 1) dust and gas concentration is too large, increasing the pre-filter or increase the dust; 2) through the large dusty gas humidity, insulation or heating, replace water repellent filter peritoneum; 3) hygroscopic dusty gas adhered to the bag surface, insulation or heating filter replaced peritoneum; 4) bag use a long time, replace the bag; 5) cleaning cycle is too long, too short injection width adjust pulse control device, shorten the cleaning cycle; 6) the bag by blowing gas oil impact, clean the filters; less than 7) cleaning intensity, adjusting the injection pressure; 8) pulse controller is disrupted, can not control the cleaning, inspection pulse controller; 9) solenoid valve does not work, coil damage, damage to the diaphragm deformation, spring failure or replacement; 10) solenoid valve does not move, does not set the loop to adjust the pulse control device reset; 11) down the wrong order, not extended injection, according to standard adjustment stop order to increase injection delay; 12) ash poor, too many plot material, cleaning the hopper, check out the ash institutions. Second, the smelter dust suction is too large, too much dust suction outlet suction reasons and treatment failure: 1, throttle shift approach: regulating, fixed throttle. 2, the filter design air volume is too large processing: Replace filter. 3, the fan does not match approach: replace the fan. 4, bag damage, loss Solution: Check the filter bag. 5, the small amount of dust bag approach: 1) cleaning cycle is too short, the blow width is too wide, adjust the pulse control device, to extend the cleaning cycle; 2) cleaning intensity is too high, adjust the injection pressure. Third, take exit smelter baghouse ash and treatment failure reasons: 1, the bag damage, loss Solution: Check the filter bag. 2. Install the seal bag bad Solution: Check reinstalled. 3, flower plate damage processing methods: maintenance of flower plate. 4, dust handling size too small: Replace the filter. 5, the cleaning cycle is too short, too wide approach injection width: Adjust the pulse control device, to extend the cleaning cycle. 6, the cleaning intensity is too strong approach: adjust injection pressure. Fourth, the reason smelter baghouse pulse cleaning system failure and treatment methods: 1, the solenoid valve does not work, can not hear the sound processing method: coil damage, damage to the diaphragm deformation, impurities stuck on the diaphragm, the diaphragm does not work reset spring failure, replace and clean the seat. 2, solenoid valve no action sequence processing method: control line connection error or fault, check the control line. 3, part of the electromagnetic valve does not deal with: Set the loop does not, adjust the pulse control device reset. 4, abnormal pulse controller damage approach: repair or replacement. 5, the gas pressure is too low packet processing method: 1) solenoid valve closed delay, put decency. Adjust pulse control device, reducing the width of the injection; less than 2) the amount of qi, regulates the air; 3) between the solenoid valve and nozzle leakage, re-install; 4) gas source processor clogged, clean up the processor. Fifth, the smelter dust collector hopper fouling causes and treatment methods: 1, ash not promptly treated: Adjust the frequency of ash. 2, ash body disorders treatment: Repair ash institutions. 3, ash leakage port Solution: Check seals. 4, dust accumulation arch approach: increasing the ash angle, manual cleaning or using blow vibration. 5, dust humidity approach: take insulation measures.
