Cartridge Dust Collector Centrifugal Fan By Xianrun Blower

Cartridge Dust Collector Working Principle

Under the function of the main centrifugal fan, dusty gas from cartridge dust collector bottom air inlet enters into the bottom chamber for dusty gas pretreatment, and then into the upper chamber; dust adsorb in the outer surface of filter cartridge, the clean gas after filtration through the cartridge enters into the net gas chamber of upper box, then come together to the outlet and exhausted out.

Custom heavy Duty Industry Fan from China Supplier

With filtering continuing, the dust accumulated on the filter cartridge surface will be more and more, accordingly, it will increase equipment running resistance. In order to ensure the system normal operation, the cartridge dust collector resistance should be no more than 1400 ~ 1600 Pa, when the resistance is over the limit range, PLC pulse automatic controller issue instructions by resistance or timing, to clean dust.

Industrial Exhaust Fans

The cartridge dust collector cleaning process is to cut off one chamber purified gas air outlet firstly, to keep the airflow in stationary state; then compress air pulse back blow dedusting; after a while natural sedimentation, open the chamber's chamber purified gas air outlet again; not only clean out the dust completely, also avoid secondary dust adsorption produced by pulsate dust extraction; so clean the dust of other chamber one by one.

Working Principle of High Pressure Blower by Xianrun Blower

In the designing, when the air pressure is between 30 KPA~200 KPA, this fan belongs to high pressure fan. Also called high pressure blower, it is different from general centrifugal fan.

High Pressure Blowers for Smelting Furnace

When the impeller rotates, due to the centrifugal force, air move to outward and forward, thus forming a series of spiral movement. Air between the impeller blades spiraling rotates accelerately and pile the outside gas into side slot, after the air entering the side channel, it is compressed, then the air return to impeller blades and rotates accelerately again.

High Pressure Blowers for Smelting Furnace

When the air moves along a spiral orbit and go through the impeller and the side channel, every impeller blade increases the degree of compression and acceleration. With the rotation, the kinetic energy of the gas increasing, the air pressure along the side of the channel increase further. When the air reach to the connection between side channel discharge and flange, the air is squeeze out of the blades and exhausted out of pump through the muffler.
