Performance Characteristics of Single Pulse Dust Collector


Release time:

May 29,2022

The pulse single-machine dust collector has strong dust removal capacity, especially suitable for dust removal of scattered dust spots with small air volume. The selection and process layout are relatively simple, which can directly treat high-concentration dust-containing exhaust gas and improve the adaptability of the unit. As a local dust source dust removal equipment, it can be widely used in the transfer points of cement conveying equipment (such as belt conveyor, hoist, conveying chute, chain plate machine, zipper machine, etc.) and various warehouses (such as homogenization warehouse, cement warehouse top and bottom).

In addition to the advantages of other single dust removal units, the pulse stand-alone dust collector also has the following advantages:

1. Online dust removal; low cost;

2. This usage is becoming more and more common. Used for belt transfer point, warehouse top, warehouse bottom, small mill, crusher, elevator and other continuous work places. Especially for the installation space is small, there is no space to change the bag, pulse single machine dust collector is more and more ideal choice for users.

Working principle of pulse single machine dust collector

The dust-containing gas enters the ash hopper from the air inlet (if there is no ash hopper, it directly enters the bag room), and then the dust-containing gas enters the filter room with the filter bag. Dust is attached to the surface of the filter bag, and the purified gas enters the upper box from the filter bag and is discharged to the atmosphere through the exhaust pipe by the fan.

As the filtration time increases, the dust attached to the surface of the filter bag increases from time to time, and the resistance increases accordingly. When the resistance rises to the set value, in order to ensure continuous work, it is necessary to stop dust removal.

The filter bags are arranged in a straight line, and each row of filter bags is equipped with a pulse valve to control compressed air pulse dust removal. The operation of the pulse valve is controlled by the program controller. During ash cleaning, the ash cleaning controller issues a command to make the pulse valve release 0.5~0.7 MPa compressed air at the moment of action. Compressed air is rushed into the filter bag at high speed through the small hole on the blowpipe facing the filter bag. When it is rushed into the filter bag, it will also induce a "secondary induced airflow" that is several times the compressed air, thereby generating an instantaneous shock wave and propagating downward along the length of the entire filter bag. By applying this mechanism, the dust accumulated outside the filter bag will peel off the filter bag wall and fall into the ash hopper. The pulse duration can be adjusted to suit the various characteristics of different dusts.

The pulse single-machine dust collector is divided into two modes: automatic control and manual control. The manual fan vacuum cleaner will automatically stop after more than ten seconds, and it can also repeatedly start the motor to vibrate and clean the dust according to the dust situation. Cleaning time can be adjusted. Automatic control refers to the automatic vibration of the single-machine ash removal mechanism and ash removal on time. The entire dust removal and filtration process is the result of the combined effects of gravity, inertia, friction and collision, electrostatic adsorption, and filtration.
