Product Details
Pulse dust collector is a new type of high-efficiency dust collector improved on the basis of bag filter. It combines the advantages of various pulse jet dust collectors and compartment back-blowing dust collectors, overcomes the shortcomings of insufficient dust cleaning intensity and uneven air distribution at the inlet and outlet, and expands the application range. It is widely used in the dust removal and purification of industrial and mining enterprises, such as metallurgy, building materials, machinery, chemical industry, mining, etc.
The body structure of the bag filter is mainly composed of the upper box, the middle box, the lower box (ash hopper), the dust cleaning system and the dust discharge mechanism.
According to the shape of the filter bag, it is divided into: flat bag (trapezoid and flat shape) and round bag (cylindrical shape).
According to the way of air in and out, it can be divided into: bottom air inlet and upper air outlet, upper air inlet and lower air outlet, and direct current type (limited to flat flat bags).
According to the filter method of the bag, it is divided into: external filter type and internal filter type.
Fibers for filter materials include cotton fibers, wool fibers, synthetic fibers, and glass fibers.
When the dust-laden gas enters the ash hopper from the air inlet pipe at the lower part of the dust collector through the deflector, the coarse dust particles fall into the ash hopper due to collision with the deflector and reduced gas velocity. The remaining fine dust particles enter the filter bag chamber along with the gas. Due to inertia, diffusion, interception, adhesion, and electrostatic effects of the filter fibers and fabrics, the dust is trapped on the inner surface of the filter bag. The purified gas passes through the filter bag and is discharged through the exhaust pipe. The dust accumulated on the filter bag is removed by gas backwashing; the removed dust falls into the ash hopper and is discharged to the ash conveying device through the double-layer ash discharge valve. Alternatively, the dust accumulated on the filter bag can be cleaned by pulse jet airflow to achieve dust removal, and the collected dust is discharged via the ash discharge device.
Product Advantage
When the dust-laden gas enters the ash hopper from the air inlet pipe at the lower part of the dust collector through the deflector, coarse dust particles fall into the ash hopper due to collision with the deflector and reduced gas velocity. The remaining fine dust particles enter the filter bag chamber along with the gas. Due to the effects of inertia, diffusion, interception, adhesion, and static electricity from the filter fibers and fabrics, dust is trapped inside the filter bag. The purified gas passes through the filter bag and is discharged through the exhaust pipe. Dust accumulated on the filter bag is removed by gas backwashing; the removed dust falls into the ash hopper and is discharged to the ash conveying device through the double-layer ash discharge valve. Alternatively, dust on the filter bag can be cleaned by pulse jet airflow to achieve dust removal, with the collected dust discharged via the ash discharge device.
Product Advantages
High dust removal efficiency, generally above 99%. The outlet dust concentration of the dust collector is within tens of mg/m³, and it offers high classification efficiency for submicron-sized fine dust particles.
Wide air volume range, from as low as a few cubic meters per minute to as high as tens of thousands of cubic meters per minute. It is suitable for flue gas dust removal in industrial furnaces and kilns, effectively reducing air pollutant emissions.
Simple structure with easy maintenance and operation.
Lower cost than electrostatic precipitators while maintaining the same high dust removal efficiency.
Can operate stably at high temperatures above 200°C when using high-temperature resistant filter materials such as fiberglass, PTFE (polytetrafluoroethylene), and P84.
Insensitive to dust characteristics and unaffected by dust properties or resistance changes.
