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.

The dust collector consists of an ash hopper, an upper box, a middle box, a lower box, and other parts. 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 filter bag is cleaned, and 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 through the filter bag opening, enters the box, and is then discharged through the air outlet.

Performance Characteristics

1. Good dust cleaning effect, high dust removal efficiency, low emission concentration, low product energy consumption, small footprint, stable and reliable equipment operation, and good economic benefits.

2. By using pulse blowing for dust cleaning, the cleaning effect can be achieved with only one blow. At the same time, the cleaning cycle is extended, which can also reduce the energy consumption of dust cleaning, and the compressed air consumption will also decrease accordingly. At this point, the degree of loss of the filter bag and pulse valve is correspondingly reduced, thereby improving the service life of the filter bag and valve plate.

3. The bag cage structure adopts a universal filter bag, making it faster, simpler, and cleaner to replace the filter bag. At the same time, the bag mouth adopts an elastic expansion ring, which has good sealing performance and is safe, firm, and reliable. The filter bag keel adopts a polygonal shape, which reduces the friction between the filter bag and the keel, thereby extending the service life of the filter bag and facilitating the unloading of the bag.

4. Adopting the method of extracting bags from the top of the chassis, when changing bags, only the skeleton needs to be extracted, and then the dirty bags are put into the ash hopper at the bottom of the equipment box and taken out through the maintenance port.

5. The box adopts an airtight design with good sealing performance. At the same time, the quality of the sealing material used for the door is checked to reduce leakage.

6. The inlet and outlet air ducts of the dust collector are tightly arranged, resulting in low airflow resistance.
