The effectiveness of bag filter dust removal is related to various factors, but mainly depends on the filter material. The filter material of a bag filter is a fabric or felt woven from synthetic fibers, fibers, or glass fibers. Sew the cloth or felt into cylindrical or flat filter bags as needed. Select filter media suitable for the application conditions based on the properties of the flue gas. Usually, when the flue gas temperature is below 120 ℃ and acid resistance is required for the filter material, polyester velvet cloth and polyester needle punched felt are often used; When dealing with high-temperature flue gas (
Whether the bag filter is operating normally directly affects whether it can be put into use on the production line. Otherwise, the bag filter is likely to quickly lose its effectiveness. The trial operation of the debugging equipment should be careful and cautious. During the trial operation of the new bag filter, special attention should be paid to checking the following points:
1. The installation status of the dust removal filter bag, whether there is any bag shedding, looseness, wear and tear after use, and the emission situation of the chimney can be visually inspected after operation to determine.
2. Pay attention to whether there is condensation in the bag chamber and whether the ash discharge system is functioning properly. To prevent blockage and erosion, severe dust accumulation can affect the production of the host.
3. The adjustment of cleaning cycle and cleaning time is an important factor affecting the dust collection function and operation status.
4. Whether the air volume and pressure and temperature at each testing point are consistent with the design
5. The rotation direction, speed, bearing vibration, and temperature of the fan.
Performance Description of Bag Dust Collector:
The design is innovative and adopts an intake structure, where coarse high-temperature particles directly fall into the ash hopper, protecting the dust filter bag.
Using long filter bags, the equipment occupies less space when the processing capacity is the same, making it easy for old factories to renovate.
The use of a partitioned separation line for dust cleaning reduces secondary adsorption of dust and lowers equipment energy consumption. The fatigue level of filter bags and pulse valves is also correspondingly reduced, doubling the lifespan of filter bags and valve plates and significantly reducing equipment operation and maintenance costs.
Maintenance and bag replacement can be carried out in separate rooms without stopping the system fan and under normal system operation conditions.
The filter bag mouth adopts a spring tensioning structure, which is easy to disassemble and has good sealing performance.
The box has been designed for airtightness and leak detection with kerosene, greatly reducing air leakage.
The entire equipment is controlled by a PLC machine to achieve automatic ash cleaning, ash unloading, automatic temperature control, and over temperature alarm.
