Pulse Jet Industrial Dust Collector System With Higher Filtering Efficiency

Industrial Use Pulse Jet Dust Collector with Higher Filtering Efficiency

Composition of Dust Collector:

1. Rectangular cylinder 2, centrifugal induced draft fan 3, pulse controller 4, bag 5, keel 6, solenoid valve 7, injection pipeline, etc.

Working Principle of Dust Collector:

    Dust enters the cylinder through the air inlet. Due to the principle of inertia or the dust absorption of the induced draft fan, dust is adsorbed on the bag. As time goes on, the dust of the bag becomes more and more, which increases and compresses the air to the bag, thereby increasing the resistance of the bag (filter), resulting in a gradual reduction of the air handling capacity. For normal work, it is necessary to clean the bag and dust. When the pulse controller triggers the control valves sequentially and opens the pulse valves, the compressed air in the air box is injected into the corresponding cloth bags through the venturi tubes, and the cloth bags expand rapidly in an instant, so that the dust accumulated on the surface of the cloth bags (filter cartridges) falls off and the cloth bags are regenerated. Dust falls into the mixing tank or the ash storage room.

Suitable for environment, large-scale working condition enterprises. Mixing station industry, flour storage industry, etc. If there are strict requirements for the environment, you can use this. Its excellent ash cleaning system and long service life. It is its biggest characteristic. In addition, it is easy to install and maintain.

     Dust collectors are widely used in cement, steel, electricity, In the food, metallurgy, chemical and other industrial fields, the overall capacity has increased several times, and it has become a large-scale dust collector. Dust collector has a large effective filtering area, low-pressure difference, low emission, small volume and long service life. It has become a new direction for the development of industrial dust collectors.

Dust collector has the following components: air inlet pipe, air exhaust pipe, pulse-jet house, collecting hopper, powder-cleaning device, air flow distribution, filters, filter cartridge and electric control device.

     The arrangement of the filter cartridge in the dust collector is very important. It can be arranged vertically on the flower panel collecting hopper, or it can be arranged obliquely on the flower panel. From the perspective of the cleaning effect, the vertical arrangement is more reasonable. The lower part of the flower plate is the filter room, and the upper part is the pulse-jet room. An air distribution plate is installed at the entrance of the dust collector.

     The air resistance for the dust collector increases with the thickness of the dust layer on the filtering bag surface. The dust removal from filtering bag can be automatically performed by offline high-pressure pulse. And the off-line high-pressure pulse cleaning is controlled by a PLC program.

First, a sub-chamber lift valve is closed, the filtered air flow is cut off, and then the electromagnetic pulse valve is opened. Compressed air will make rapid expansion into the filtering bag within a short time. And this will make the filtering bag expand, which will make the dust on the surface of filtering bag fall down into the hopper. After the dust cleaning is completed, the electromagnetic pulse valve is closed, the poppet valve is opened, and the chamber is restored to the filtering state. The cleaning of each chamber is performed sequentially, from the cleaning of the first chamber to the start of the next cleaning, which is a cleaning cycle. The falling dust falls into the ash hopper and is discharged through the ash valve.
