Design considerations of bag filter in coal preparation plant. Bag filter in coal preparation plant is mainly designed based on the principle of saving investment as much as possible. The new design concept has been put into production and advanced equipment has been put into production. The dust collector is used in coal preparation. The use effect of the plant is obvious, and the purpose of dust removal and purification of the exhaust gas is achieved. The coal preparation plant dust collector is an explosion-proof pulse bag dust collector designed by our company. The bag dust collector has an exhaust valve. The dust collection bag adopts antistatic Filter materials, fans, and motors are explosion-proof to ensure safe use. Design considerations for bag filters in coal preparation plants
The working principle of the bag filter in the coal preparation plant is: After the coal dust is crushed, it is discharged into the receiving device (belt conveyor) at the bottom of the crusher through the chute. Due to the gap between the inlet and the outlet, the pulverized coal flow Shearing effect with the surrounding air, the air is sucked into the material flow. The pulverized coal flow gradually diffuses, and the mutual suction effect is that the dust is continuously scattered outward. At the same time, the conveyor belt is moved by a fast train, which is impacted by the pulverized coal gas flow and the surface of the belt During inspection, dust will be raised at the discharge opening and flying around. Install a dust collection hood at the discharge port to collect coal powder, and the coal powder is adsorbed on the dust collector through the pipeline to complete the dust removal process. Design precautions for bag dust collectors in coal preparation plants
Design precautions of bag filter in coal preparation plant;
1. Dust cover: divided into sealed cover and semi-sealed cover
2. Pipeline: divided into main pipe and branch pipe
3. Manually adjust the air valve
4. Dust removal equipment: bag dust collector
5. Coal preparation plant dust collector unloading: The equipment is automatically unloaded to the belt by the conveyor and sealed at the belt unloading place to avoid secondary flying.
6. Due to the large amount of dust generated by fans, motors and coal washing plants, if they are not careful, these dusts can cause explosions. Therefore, when designing bag dust collectors in high-efficiency coal washing plants, a variety of flame-proof and explosion-proof designs must be implemented.
7. In order to prevent dust from accumulating on the beams and partitions, all these parts are equipped with dust-proof plates, which can effectively prevent dust accumulation. In addition, in order to prevent dust humidity, steam pipe insulation or tube electricity is added to the ash wall. Heater.
8. Pulverized coal is a kind of dust that is easy to generate static electricity, which can easily cause combustion or explosion. Therefore, the vibrating screen dust collector of Shengjing Environmental Protection Coal Preparation Plant is equipped with anti-static dust bag.
9. In order to control the danger to a small degree, the vibrating screen dust collector of the coal preparation plant is also provided with safety holes and fire extinguishing equipment.
10. The box and the top cover of the vacuum cleaner are provided with a folding plate type explosion-proof door, and an oblique pin fastener is added between the top cover and the clean room. The explosion-proof performance is better and the use is safer;
11, matching anti-static cloth bags, effectively eliminate the hidden danger of coal explosion
12. Ash hopper insulation: take thermal insulation or heat tracing measures to ensure safe operation;
13. Fully automatic control: PLC electrical control system is adopted for simple operation, stable and reliable;
