Working principle:
When the pulse bag filter works normally, the dusty gas enters the ash hopper from the air inlet. Due to the rapid expansion of gas volume, some coarse dust particles fall into the ash hopper due to inertia or natural sedimentation, and most of the remaining dust particles rise with the airflow and enter the bag room. After being filtered by the filter bag, 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 the air outlet, thus achieving the purpose of dust removal. With the continuous filtration, the resistance of the device is also rising. When the resistance reaches a certain value, the ash cleaning controller issues an ash cleaning command. First, the lift valve plate is closed to cut off the filtered air flow. Then, the dust removal controller sends a signal to the pulse solenoid valve. Because the pulse valve sends the high-pressure reverse airflow used for cleaning the dust into the bag, the filter bag expands rapidly and produces strong jitter, so that the dust outside the filter bag is shaken off, thus achieving the purpose of cleaning the dust. Because the equipment is divided into several box areas, the above process is carried out box by box. When one tank area is cleaned, other tank areas are still working normally, which ensures the continuous normal operation of the unit. The key to deal with high-concentration dust is that the cleaning time required by this kind of strong cleaning is very short (only 0. 1 ~ 0.2s for one injection).
Product description:
The high-efficiency dust collector with injection structure independently developed by our company can produce a balanced injection force on the whole filter bag/filter cartridge when injecting the filter bag, effectively prevent the filter bag/filter cartridge from local failure or excessive dust removal due to different injection forces in the length direction, ensure the long-term stable operation of the filter bag/filter cartridge and improve the service life of the filter bag/filter cartridge.
