The dust collector of the coal preparation plant is mainly designed on the principle of saving investment as much as possible. New design concepts have been put into production, and advanced equipment has been put into production. The invention has obvious application effect on the dust collector of the coal preparation plant. The bag material for the dust collector of the coal preparation plant can achieve the purpose of dust removal and purification of exhaust gas.
The coal preparation plant dust collector is an explosion-proof pulse bag type dust collector designed by our company. The bag dust collector box is provided with an exhaust valve. The bag material dust collection bag for the coal preparation plant dust collector uses antistatic filtering materials, and the fan and motor are explosion-proof To ensure safe use.
The dust removal point of the bag filter in the coal preparation plant mainly includes the vibrating screen, the inlet, the outlet and the chute. This design is also for better structural optimization, which greatly improves the energy saving effect. During the work, large The rough stone is squeezed, impacted, broken, and then the chute is conveyed to the belt conveyor below. Then collect the dust generated in the process to prevent the dust from polluting the environment under the drive of ambient air. At the same time, the dust collector of the coal preparation plant adopts a closed design, which plays a good role in collecting some high-concentration dust.
Technical principle of pulse bag dust collector in coal preparation plant: After the coal dust is broken, it is discharged into the receiving device (belt conveyor) under the crusher through the chute. Due to the gap between the inlet and the outlet, the pulverized coal flow and The surrounding air produces a shearing effect, and the air is sucked into the material flow. The pulverized coal flow gradually diffuses, and the mutual suction effect is that the dust continues to fly 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 conveyor belt. During the inspection, dust will be raised at the discharge port and fly around. A dust collecting hood is installed at the discharge port to collect coal powder, and the coal powder is adsorbed on the dust collector through a pipeline to complete the dust removal process.
Features and advantages of dust collectors in coal preparation plants
1. It has a series of explosion-proof devices, making the operation more stable and reliable.
2. Designed with ash bucket equalization technology to ensure uniform gas source distribution and prolong the service life of the filter bag.
3. Pulse off-line dust removal, the dust removal efficiency is over 99. 99%, and the dust has no secondary adsorption, which is especially suitable for handling high-concentration flue gas;
4. High temperature flue gas is used for back blowing, which effectively prevents condensation and bagging.
5. The use of new easy-to-clean dust filter materials and reliable flue gas temperature tracking system can adapt to various flue gas conditions.
6. The present invention reduces local resistance loss and avoids problems such as inconvenient installation of filter bags.
7. Simple operation and good reliability.
Brief introduction of bag material for dust collector of coal preparation plant:
The anti-static dust collector bag is made of anti-static polyester needle felt (made of conductive fibers such as conductive fiber yarns incorporated into the base fabric warp yarns of the needle felts or conductive fibers incorporated into chemical fibers) They have excellent antistatic properties and are used in industries such as surface dust, chemical dust, and coal dust that may explode during electrostatic discharge. They are the most ideal choice for explosion-proof dust removal.
When the concentration of industrial dust reaches a certain level (Ie explosion limit), it is easy to cause explosion and fire when encountering factors such as electrostatic discharge sparks or external ignition. For example, in the case of electrostatic discharge, surface dust, chemical dust and coal dust may It can explode. In the field of bag dust removal, if the bag is required to remove dust, the filter material used to make the bag must have antistatic performance. Our company absorbs and digests foreign technology. According to domestic blast furnace gas, coal mill dust removal, coal mill grinding Industrial dust removal and other industries need to develop and produce anti-static needle-punched filter felts. The production of anti-static filter cloth not only has the production process of ordinary needle-punched felts, but also needs to mix conductive fibers or stainless steel conductive materials into the chemical fibers produced by needle-punched felts. , So that the antistatic needle felt felt dust collector bag has better antistatic performance.
