The correct usage method of pulse bag dust collector: After purchasing a pulse bag dust collector, how should customers use it correctly? I believe many customers only have a rough understanding. Below, we will explain in detail to help you understand the usage method of pulse bag dust collector in daily work, extend the service life of the dust collector, and save expenses for the enterprise. 1. During the operation of the pulse bag filter, the enterprise should have dedicated personnel to manage it and keep corresponding records in sequence. 2. Enterprise managers should be familiar with the principle, performance, some simple technical parameters, and maintenance methods of pulse bag dust collectors. 3. The parts that need lubrication on the pulse bag filter should be regularly replenished with lubricating oil by staff. 4. Regularly check the normal performance of the blowing system every time the machine is turned on and off, and promptly replace and solve any problems found. Is there any air leakage in the cylinder and flange? Sometimes, it is necessary to replace the sealing ring in a timely manner. 5. When the sealing strip on the maintenance door is found to be aging, it should be replaced in a timely manner. 6. The technical parameters of the pulse bag type dust collector, such as gas volume, working temperature, smoke concentration, etc., should be checked regularly to promptly identify and solve problems. 7. Enterprises can regularly check the operation status of equipment based on changes in the resistance value of pulse bag dust collectors. 8. Enterprises should regularly replace vulnerable parts in equipment, inspect the condition of the air circuit and ash discharge system, and promptly identify and solve problems. 9. Regularly check the water accumulation in the compressed air water separator and promptly remove any issues that may arise. 10. When the pulse bag filter is shut down, it is necessary to keep the filter and fan working for a period of time to remove moisture and dust from the filter. It is necessary to repeatedly carry out the operations of cleaning and discharging dust. Daily operation process of pulse bag filter: 1. Pulse bag filter induced draft fan suction: During normal operation, under the action of the induced draft fan, the dusty gas is sucked into the intake manifold and evenly distributed to each intake chamber through each intake branch pipe; 2. Dust removal bag dust interception: Dust containing gas flows into the filter bag, and a large amount of dust is trapped on the filter bag, while the airflow passes through the filter bag to achieve purification; 3. Compressed air back blowing: As the dust adhering to the surface of the filter bag fabric thickens, the resistance of the pulse bag dust collector continues to rise, and regular dust cleaning is required. The entire dust cleaning process is mainly completed through the action of high-pressure gas storage bags, solenoid valves, spray pipes, and dust cleaning control mechanisms. Firstly, the control system automatically opens the solenoid valves in sequence, and high-pressure air is blown back through the spray pipe, causing the dust adhered to the dust bag to be shaken and fall off into the ash hopper; 4. Restoration of filtration: After blowback, the solenoid valve is closed, and the dust cleaning operation of the system is completed, and the filter bag returns to the filtering state; 5. Pulse bag dust collector cycle cleaning and filtration: The control system opens other solenoid valves to clean other filter bags. After the cleaning cycle, all filter bags achieve the purpose of cleaning and the dust collector returns to the filtering state; 6. Ash hopper discharge: The ash discharge device and dust collector operate simultaneously, and the ash should be cleaned in a timely manner. It is recommended to avoid accumulating ash in the ash hopper as much as possible, otherwise it will affect the service life of the filter bag; 7. Exhaust clean flue gas: The purified airflow enters the water film dust collector and desulfurizer through the bag chamber. The pulse bag filter operates with external filtering and air intake, and uses pulse back blowing for dust cleaning (online dust cleaning). The inlet allows a gas dust concentration of 1000g/m3 (standard), and the outlet gas dust concentration is ≤ 50g/m3 (standard).
