The vertical boiler dust collector is installed on the automatic soot blowing device of the boiler. During operation, high-temperature flue gas enters the filtering chamber through the air inlet and is filtered by the filter bag of the boiler bag filter. Coarse dust particles directly enter the bottom of the ash hopper to improve the dust removal effect. At the same time, the airflow speed is slow, and as the airflow changes direction, it enters the filtering box, and slight dust is retained on the bag. The surface of the filter bag is deposited, and clean gas enters the upper outlet of the clean air chamber of the box through the filter bag. The high-pressure compressed air of the pulse generator is discharged into the atmosphere, and the filtered dust adheres to the bag wall and increases. When the pulse generator sets the time or pressure, the pulse controller sequentially opens the pulse solenoid valve at intervals, and the jet tube pulse blows the dust in each row of bags to compress the air bag, causing the compressed air to quickly expand and deposit dust in the bag. At this time, the filter bag is filtered and the dust on the outer wall of the filter bag is removed, stripped to the ash hopper, and discharged by the ash discharge valve.

Performance characteristics:

1. The air inlet and outlet are integrated, using inclined partitions for uniform airflow distribution. The dusty gas is propelled by sparks and resistance dust, preventing direct erosion of the bag by dust and reducing the dust concentration. The pulse valve prolongs the life of the bag.

2. The filter bag frame adopts a circular shape, reducing the friction between the bag and the skeleton, extending the service life of the filter bag, and making it easy to unload the bag.

3. Using the above method, when changing the bag and opening the top cover door, the operating conditions of the skeleton were changed.

4. Constant pressure dust control timing, manual control, and complete cleaning according to the cycle

5. The filter bag is made of cloth and operates at a temperature below 200 ℃.

6. The sealing material of the dust collector is made of materials.

7. The soot blowing pipe is lengthened, and the pulse solenoid valve is kept away from high-temperature flue gas to avoid damage to the pulse solenoid valve plate caused by high temperature.

8. The filter bag mouth adopts an elastic sealing ring, which has good sealing performance and is firm and reliable.

9. The dust collector is wrapped with a rock wool insulation layer to prevent condensation inside the boiler bag filter.

10. Install a bypass valve at the air inlet to prevent high temperature damage to the cloth bag.

11. Installation of high temperature alarm leak detection device and filter bag device.

The vertical boiler dust collector is a bag filter designed after absorbing similar product technology improvements. The boiler bag filter adopts high-pressure (0.5-0.7Mpa) high flow pulse valve to blow the filter bag cleaning technology one by one. Compared with other domestic single filters, it has the characteristics of high ash kinetic energy and high efficiency. It has the advantages of small size, light weight, simple and compact structure, easy installation, and convenient maintenance (external filter type). It is widely used in building materials, metallurgy, mining, chemical industry, coal, non-metallic mineral powder processing, and dust gas purification treatment system. It is an ideal environmentally friendly dust removal equipment.
