　　Product Introduction of Pulse Dust Collector:

　　Pulse dust collector is a new type of pulse dust collector improved on the basis of bag filter. It combines the advantages of various pulse jet dust collectors with chamber back blowing, overcomes the disadvantages of insufficient cleaning intensity and uneven distribution of inlet and outlet air, and expands the application range.

　　Pulse dust collector is a device that, when dusty gas enters the dust collector through the air inlet, it first encounters the inclined plate and baffle in the middle of the air inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down, and due to inertia, coarse particles of dust in the gas directly flow into the ash hopper. Playing a role in pre dust collection, the airflow entering the ash hopper is then deflected upwards and captured on the outer surface of the filter bag through the filter bag equipped with a metal skeleton inside. The purified gas enters the upper clean room of the filter bag chamber and is collected at the air outlet for discharge. During the process of purifying the dusty gas through the filter bag, as time increases, more and more dust accumulates on the filter bag, increasing the resistance of the filter bag and gradually reducing the processing air volume. To work normally, the resistance should be controlled within a range (140-170 mm water column). Once the range is exceeded, the filter bag is cleaned. During cleaning, the pulse control instrument sequentially triggers each control valve to open the pulse valve. The compressed air in the air bag is sprayed from each hole of the spray pipe through the Venturi tube to the corresponding one. Inside the filter bag, the bag instantly expands rapidly, causing the dust accumulated on the surface of the filter bag to fall off, The filter bag returns to its initial state. The dust falls into the ash hopper and is discharged from the machine through the ash discharge system. As a result, the dust accumulated on the filter bag is periodically pulse blown to clean the dust, allowing the purified gas to pass through normally and ensuring the operation of the dust removal system.

　　Working principle of pulse dust collector:

　　Pulse dust collector refers to the method of removing dust attached to the filter medium (bag or filter cartridge) by blowing compressed air; Depending on the size of the dust collector, there may be several sets of pulse valves controlled by a pulse controller or PLC. Each set of pulse valves is opened to remove dust from the bag or filter cartridge it controls, while the other bags or filter cartridges work normally. After a period of time, the next set of pulse valves is opened to clean the next part of the dust collector, which consists of ash hopper, upper box, middle box, lower box, etc. The upper, middle, and lower boxes are divided into compartments. During operation, dusty gas enters the ash hopper through the air inlet duct. Coarse dust particles directly fall into the bottom of the ash hopper, while fine dust particles enter the middle and lower boxes upwards with the turning of the airflow. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection pipe exhaust duct, and is discharged to the atmosphere through the exhaust fan. The dust cleaning process involves first cutting off the clean air outlet duct of the room, so that the bag in the room is in a state of no airflow passing through (stopping the air and cleaning the dust in each room). Then, the pulse valve is opened and compressed air is used for pulse blowing to clean the dust. The shut-off valve is closed for a sufficient time to ensure that the dust peeled off from the filter bag settles in the ash hopper after spraying, avoiding the phenomenon of dust adhering to the adjacent filter bag surface with the airflow after leaving the filter bag surface. The exhaust valve, pulse valve, and ash discharge valve are fully automatically controlled by a programmable controller. The dusty gas enters through the air inlet, and when passing through the ash hopper, some large particles of dust in the gas are separated by inertia and gravity, and directly fall into the bottom of the ash hopper. The dusty gas enters the filter bag filtration area of the middle box after passing through the ash hopper. The gas passes through the filter bag, and the dust is trapped on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag opening and is then discharged through the air outlet.
