characteristic:

This dust remover adopts the technology of blowing and blowing dust by stopping air pulse in separate rooms, which overcomes the shortcomings of conventional pulse dust remover and reverse blowing dust remover in separate rooms. It has strong dust removal capacity, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, low steel consumption, small floor area, stable and reliable operation, and good economic benefits. It is applicable to the purification of dusty gas and the recovery of materials in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.

As the chamber air stop pulse injection is used for soot cleaning, the purpose of thorough soot cleaning can be achieved once, so the soot cleaning cycle is extended, the energy consumption of soot cleaning is reduced, and the air consumption can be greatly reduced. At the same time, the fatigue degree of the filter bag and pulse valve is reduced accordingly, thereby doubling the service life of the filter bag and valve piece.

The bag replacement for maintenance can be carried out in different rooms without stopping the system fan and under the normal operation of the system. The mouth of the filter bag adopts elastic expansion ring, which has good sealing performance and is firm and reliable. The filter bag keel is polygonal, which reduces the friction between the bag and the keel, prolongs the service life of the bag, and is convenient for bag unloading.

The upper bag drawing method is adopted. After the skeleton is drawn out during bag changing, the dirty bag is put into the lower ash hopper of the box and taken out from the manhole, which improves the bag changing operation conditions. The box is designed with good air tightness. The inspection door is made of excellent sealing materials. During the manufacturing process, kerosene is used for leak detection, and the air leakage rate is very low. The inlet and outlet air ducts are arranged compactly with small air flow resistance.

working principle:

When the pulse bag filter equipment works normally, the dusty gas enters the ash hopper from the air inlet. Due to the rapid expansion of the gas volume, part of the coarse dust particles fall into the ash hopper due to inertia or natural sedimentation, and most of the other dust particles rise with the air flow and enter the bag chamber. After being filtered by the filter bag, the dust particles are retained outside the filter bag. The purified gas enters the upper box from the inside of the filter bag, and then is discharged into the atmosphere through the valve plate hole and exhaust outlet, So as to achieve the purpose of dedusting. With the continuous filtration, the resistance of the dust remover will also rise. When the resistance reaches a certain value, the dust removal controller will send a dust removal command. First, close the lifting valve plate to cut off the filtered air flow; Then, the dust removal controller sends a signal to the pulse solenoid valve. As the pulse valve sends the high-pressure reverse air flow used for dust removal into the bag, the filter bag swells rapidly and produces a strong shake, causing the dust outside the filter bag to shake off, so as to achieve the purpose of dust removal. As the equipment is divided into several box areas, the above process is carried out box by box. When one box area is cleaned, the remaining box areas are still working normally, ensuring the continuous and normal operation of the equipment. The key to handling high concentration dust is that this kind of strong dust removal requires very short dust removal time (only 0.1~0.2 s for each injection)
