Description
Technical Field
The utility model relates to a self-interacting pulse dust collector.
Background
The pulse dust collector is used for removing dust attached to a filter medium (a cloth bag or a filter cylinder) by a method of blowing compressed air; several groups of pulse valves are possible according to the size of the dust remover, the pulse valves are controlled by a pulse controller or a PLC, one group of pulse valves are opened each time to remove dust of the part of the cloth bag or the filter cylinder controlled by the pulse valves, other cloth bags or the filter cylinders work normally, the next group of pulse valves are opened after a period of time, the next part of dust remover is cleaned, and the dust remover comprises a dust hopper, an upper box body, a middle box body, a lower box body and the like, and the upper box body, the middle box body and the lower box body are of a chamber-divided structure. When the dust-free dust collection box works, dust-containing gas enters the dust hopper from the air inlet duct, coarse dust particles directly fall into the bottom of the dust hopper, fine dust particles turn upwards along with air flow and enter the middle box body and the lower box body, dust is accumulated on the outer surface of the filter bag, and the filtered gas enters the upper box body to the clean gas collection pipe-air outlet duct and is exhausted to the atmosphere through the air exhaust fan. The ash cleaning process is to cut off the air duct at the clean air outlet of the chamber to make the cloth bag in the state of no air flow passing through (air stopping and ash cleaning in different chambers). Then the pulse valve is opened to carry out pulse injection ash removal by compressed air, the closing time of the stop valve is enough to ensure that dust stripped from the filter bag after injection is settled to the ash bucket, the phenomenon that the dust is attached to the surface of the adjacent filter bag along with airflow after being separated from the surface of the filter bag is avoided, the ash removal of the filter bag is thorough, and the programmable controller carries out full-automatic control on an exhaust valve, the pulse valve, an ash discharge valve and the like. Dust-containing gas enters from the air inlet, and when the dust-containing gas passes through the dust hopper, part of large-particle dust in the gas is separated out under the action of inertia force and gravity and directly falls into the bottom of the dust hopper. The dust-containing gas enters the filter bag filtering area of the middle box body after passing through the dust hopper, the gas passes through the filter bag, dust is blocked on the outer surface of the filter bag, and the purified gas enters the upper box body through the filter bag opening and then is discharged from the air outlet. However, in daily use, the pulse valve is very easy to damage, especially the diaphragm breaks through, compressed air in the air bag is not blocked by the diaphragm of the pulse valve and enters the dust remover, so that the pressure of the compressed air in the air bag is insufficient, the starting frequency of the front-stage air compressor is improved, the pressure of blowing air is insufficient, the integral dust removal efficiency of the pulse dust remover is reduced, and the pulse dust remover needs to be stopped and maintained when the pulse valve is replaced.
