The working principle of the dust removal equipment Let the dust removal equipment manufacturers tell you!

pulse

The dust collector is mainly composed of an upper box body, a middle box body, an ash hopper, an air inlet equalizing pipe, a support filter bag, an injection device, and an ash discharge device. Dust-containing gas enters the ash hopper of each compartment from the air inlet equalizing pipe of the precipitator, and under the guidance of the ash guide device, the large particles of dust are separated and directly fall into the ash hopper, while the finer dust enters uniformly. The middle box is adsorbed on the outer surface of the filter bag, and the clean gas passes through the filter bag and enters the upper box, and is discharged into the atmosphere through the off-line valves and exhaust pipes. With the progress of the filtering conditions, the dust on the filter bag accumulates more and more. When the equipment resistance reaches a limited resistance value (generally set to 1500Pa), the dust cleaning control device sets the differential pressure or the dust cleaning time. After the set value automatically closes the off-line valve in the first room, the electronically controlled pulse valve is opened according to the set procedure to stop the air blowing. The compressed air is instantly blown to increase the pressure in the filter bag and shake off the dust on the filter bag (Even if sticky fine dust can be cleaned thoroughly), it will be discharged into the ash bucket by the ash discharge mechanism.

whirlwind

After the bypass of the cyclone dust collector, the working principle is that the dust-containing gas enters tangentially from the inlet. At the same time as the airflow obtains the rotating motion, the airflow is separated up and down to form a double spiral movement. The thicker dust particles are separated to the outer wall by the lower spiral airflow, and some of the dust is drawn out from the central opening of the bypass separation chamber, and the remaining dust is brought to the ash bucket by the downward airflow. The upper spiral airflow has a gathering effect on fine particle dust, thereby improving the dust removal efficiency. This part of the fine dust particles is formed by the upper spiral airflow belt to the upper part, forming a strongly rotating upper dust ring under the top cover, and enters the upper opening of the bypass separation chamber together with the upper spiral airflow, and is introduced into the cone through the return air outlet. Converges with the internal air flow, the purified gas is discharged from the exhaust pipe, and the separated dust enters the hopper.

Stand-alone

Dust-containing gas enters the box and is filtered by a flat cloth bag filter. The dust is trapped on the outer surface of the filter bag. The purified gas enters the fan through the filter bag and is directly sucked out by the fan. With the increase of the filtering time, the filter bag The dust adhered to the outside is also increasing, and the resistance of the filter bag is correspondingly increased, which affects the dust removal efficiency. At this time, the vibrating mechanism is started to shake the dust adhered to the surface of the filter bag. The dust falling in the drawer is manually Pull out to clear.

Working principle of stand-alone dust collector:

Dust-containing gas enters the box through the air inlet, and is filtered by the filter bag. The dust is trapped on the outer surface of the filter bag. The purified gas is discharged from the outside of the box by the fan through the air outlet, and is directly discharged into the room. Drain outdoors).

With the continuous operation of the host, the dust adhered to the outside of the filter bag increases continuously, which increases the resistance of the equipment. Therefore, it is necessary to clean up the dust, so that the dust stuck to the outside of the filter bag is shaken down, and then falls to the dust collector through the ash bucket ( Drawer), manually removed.

Multi-pipe

The dust-containing gas enters the gas distribution chamber from the main intake pipe, and then enters the annular gap between the ceramic cyclone body and the deflector. The deflector changes the gas from linear motion to circular motion. Most of the rotating airflow spirals downward from the cylinder along the cyclone and flows toward the cone. The dust-containing gas generates centrifugal force during the rotation process, and the density is greater than The dust particles of the gas are thrown towards the wall of the cylinder. When the dust particles are in contact with the cylinder wall, they lose their inertia and rely on the momentum of the inlet speed and downward gravity to fall along the wall surface into the ash discharge port and enter the total ash hopper. When the rotating descending external swirling air reaches the lower end of the cone, the cone rotates in the same direction of rotation as the spiral tube axis from the bottom to the top to continue the spiral flow (clean air), passing through the ceramic cyclone exhaust pipe. Enter the exhaust chamber and exit through the main exhaust port.
