Bag filter on the top of the white ash kiln silo

The bag filter on the top of the white ash kiln adopts filtering materials. Based on the characteristics of rotary kiln flue gas in China, LF series composite filter materials are mixed with 20% P84 and base cloth PTFE. The PTFE impregnation used in post-processing not only solves the problem of high flue gas temperature in rotary kilns, but also endows the filter material with performance, making it suitable for the tail of carbide slag cement kilns.

The cleaning structure of the bag filter on the top of the white ash kiln silo:

The bag filter on the top of the white ash kiln has the advantages of low dust removal equipment resistance, small footprint, low operating energy consumption, and low maintenance workload. At present, it has been widely used in lime kiln flue gas purification, industrial dust control, material transportation and recycling, and other places. The dusty gas flows from the intake pipe to the lower part of the middle box and enters the ash hopper. There is no wind deflector inside the middle box, allowing the airflow to be evenly distributed through the filter bag. After the dust removal filter bag, dust clogs the outer surface of the filter bag. The purified gas is discharged through the air outlet of the box.

Due to the lack of industrial kiln flue gas dust removal technology at that time, our company's early development of industrial kiln flue gas dust removal technology, coal-fired kiln flue gas dust removal materials, and external equipment quality were not up to standard, especially the quality of cloth bags, which have not yet been promoted.

In recent years, the production technology of supporting components such as filter materials has been greatly improved, and the shortcomings of bag filters in kiln dust removal technology have been overcome; At the same time, environmental protection requirements are constantly increasing. With the introduction of new standards, electrostatic precipitators can no longer meet the treatment requirements for flue gas emissions in kilns, and bag filters replacing electrostatic precipitators have become an inevitable trend; Therefore, our company has drawn on a series of advantages of bag filter and designed a new generation of white ash kiln bag filter.

The bag filter on the top of the white ash kiln silo is a modern level white ash kiln dust collector technology product that combines current white ash kiln dust collector technology for a long time, combined with technical experience and achievements. It is a large-scale dust removal equipment with high air volume, good dust removal efficiency, and easy operation and maintenance.

The characteristics of the bag filter on the top of the white ash kiln:

1. Pulse jet technology is used for bag dust collectors in white ash kilns. Choosing low resistance, long-life diaphragm electromagnetic pulse valves, reliable nozzle design, tooling molds, and bag dust removal power.

2. The bag filter of the white ash kiln uses filtering materials. Based on the characteristics of rotary kiln flue gas in China, LF series composite filter materials are mixed with 20% P84 and base cloth PTFE. The PTFE impregnation post-treatment not only solves the problem of high flue gas temperature in rotary kilns, but also endows the filter material with performance, making it suitable for the tail of carbide slag cement kilns.

3. The bag filter of the white ash kiln adopts a cage bone with protection. Install the cold stamped Venturi protection tube on the top of the cage head for vertical spraying of the bag mouth without increasing system resistance.

4. Good online maintenance techniques. The kiln bag dust collector adopts lift valve technology to achieve continuous maintenance function of the dust collector. The lifting valve is equipped with a protective device to prevent dust collector failure caused by lifting valve issues, without affecting the operation of the rotary kiln.

5. PLC (Programmable Logic Controller) technology. Adopting PLC programmable controller control, with communication interface with system DCS, it can achieve manual/automatic control of bag filter.

6. The bag filter adopts a flue gas guide device, with flow obstruction and guide. This device can evenly distribute smoke into each bag chamber.
