Applicable industries: food industry, chemical industry, light industry, electronics industry, etc.
Grain processing plant selection is particularly important. Customers must provide accurate parameters so that we can choose the right model for you and save you costs.
Use and maintenance of bag filter in grain factory:
Timely and effectively solving the faults in the operation of the dust collector can not only ensure the continuity of production, but also prolong the service life of the dust collector. Common failures of the dust collector are as follows:
The amount of air suction of the dust collector is reduced, and the air suction port cannot effectively capture dust. Causes and solutions:
① Duct is blocked and the damper is shifted: clean the duct and fix the damper.
② Dust collector and air duct are not tightly sealed. Partial air leakage: Check the tightness of the dust collector and duct.
③ The air volume of the dust collector is too small: replace the dust collector.
④ Fan does not match: Replace the fan.
⑤ The dust bag is blocked:
◆ Dust-containing gas concentration is too large, increase pre-filtration or increase dust collector;
◆ Excessive humidity of dust-containing gas, heat preservation or heating, replace with water-repellent peritoneal filter material;
◆ Dust-containing gas has strong hygroscopicity and adheres to the surface of the filter bag, keeps it warm or heated, and replaces it with peritoneal filter material;
◆ The filter bag is used for a long time. Replace the filter bag;
◆ The dust cleaning cycle is too long and the spray width is too short. Adjust the pulse controller to shorten the dust cleaning cycle.
◆ The filter bag is affected by the gas contained in the blowing gas, and the filter is cleaned;
◆ Insufficient dust removal strength, adjust the injection pressure;
◆ The pulse controller appears disordered and cannot control dust removal. Check the pulse controller.
◆ The solenoid valve does not work, the coil is damaged, the diaphragm is damaged and deformed, the spring is invalid, and it is replaced;
◆ The solenoid valve does not work, the setting circuit is wrong, adjust the pulse controller to reset;
◆ The shutdown order is not correct. There is no prolonged injection. Adjust the shutdown order according to the specifications and increase the injection delay.
◆ Poor ash discharge, excessive accumulation of materials, clean ash bucket, check ash discharge mechanism.
The dust suction of the dust collector is too large, and the suction port sucks too much dust. Causes and solutions:
① Damper shift: Adjust and fix the damper.
② The air volume of the dust collector is too large: replace the dust collector.
③ Fan does not match: Replace the fan.
④ The filter bag is damaged or falling off: Check the filter bag.
⑤ The dust accumulation in the filter bag is too small:
◆ The cleaning cycle is too short, and the spray width is too wide. Adjust the pulse controller to extend the cleaning cycle.
◆ The dust removal intensity is too high, adjust the injection pressure;
◆ Dust at the outlet of the dust collector. Causes and solutions:
a) The filter bag is damaged or shedding: check the filter bag;
b) The filter bag is not properly sealed: check for reinstallation;
c) Flower board damage: repair flower board;
d) The dust particle size is too fine: replace the filter material;
e) The cleaning cycle is too short and the spray width is too wide. Adjust the pulse controller to extend the cleaning cycle.
f) The cleaning strength is too strong, adjust the injection pressure.
Causes and treatment methods of pulse dust cleaning system failure:
① No sound can be heard when the solenoid valve is inactive: the coil is damaged, the diaphragm is damaged and deformed, and impurities are stuck on the diaphragm. The diaphragm cannot be reset normally, the spring fails, replace and clean the valve seat.
② The solenoid valve does not operate in sequence: the control line is connected incorrectly or broken, check the control line.
③Some solenoid valves do not work: the setting circuit is wrong, adjust the pulse controller to reset.
④ Pulse controller abnormal damage: repair or replace.
⑤ Air bag pressure is too low:
◆ The solenoid valve is closed for a long time, and the amount of air released is large. Adjust the pulse controller to reduce the spray width;
◆ Insufficient air supply volume, adjust air source;
◆ Air leakage between solenoid valve and nozzle, reinstall;
◆ Air source processor is blocked, clean the processor;
◆ Causes and treatment methods of ash accumulation in dust collector:
a) The ash discharge is not immediate: adjust the ash discharge frequency;
b) The ash discharge mechanism is abnormal: repair the ash discharge mechanism;
c) Air leakage at the ash outlet: check the seal;
d) Dust accumulation arch: increase the angle of ash discharge, clean up manually or use a vibrator;
e) High dust and humidity: take thermal insulation measures.
