Introduction

With high cleaning efficiency, PPC Series Pulse Jet Bag Filter incorporates the advantages of other bag filters as compartmental blow-back, pulse jet cleaning. It overcomes disadvantages of weak cleaning strength of blow-back as well as synchronous working of pulse jet cleaning and filtering, expaning the field of application, it is featured with strong cleaning strength, high effective, long life. It is suitable to the treatment of high concentration dust, simplifying the technical process of dust treatment and reducing investment of device.

Application:

This series of bag filter is widely used in cement, metallurgy, machinery, chemical and refractory industries, especially for dust collectiom system, such as crushing, packaging, warehouse, clinker cooler and various grinding mill in cement plant. In additon, it can be used in dust collection of coal mill. However, in the dust collection of ball mill, anti-explosion equipment should be added and related struture changed.

Working Principle:

From the intake, the air with dust enters into the ash silo through a slanting partition. With the speed slowing down, the big particle in the air falls into the silo due to its gravity, while the fines goes into the filtering chamber and attaches to the surface of filter bags. Then the purified air continues into the top cleaning room. Finally, the air is collected in the cleaning room and sucked out to the atmosphere by the main fan.

We supply the spart parts for bag filter, such as filter bag, bag cage, star-shaped discharger, pulse valve, pulse controller etc

Features

1. New and advanced dust removing concept. No air pipe. Pulse valve is assembled at the side the chamber shell or top. No need to disassemble and assemble the air pipe when replacing the bags.

2. High performance pulse is applied to replace many smaller pulse to reduce the maintenance as much as possible.

3. Multi-chamber and off-line dust removing. Long life of filter bag.

4. Available for high density dust containing air collection, for example, O-Sepa separator, the dust content of which will reach 1000g/Nm3.

5. Air tank will reduce the pressure decrease caused by equipment.
