Bag filter for stone material factory

The bag filter in the stone material factory is a circular shell type dust collector with high processing air volume, good dust removal effect, convenient dust removal, operation, and maintenance, and a small footprint.

1. The dust collector in the quarry consists of an upper box body, a middle box body, an ash hopper, a bracket, a filter bag component, a reverse blowing and cleaning mechanism, and an ash discharge valve.

2. Dust collection and filtration system: mainly composed of filter bags, bag cages, flower board components, ash hoppers, and tangential air intake system.

3. Ash cleaning and unloading system: high-pressure fan, rotary blowback pipe, and deceleration motor.

4. Electric control system: Automatic control system.

The bag filter in the stone factory has a circular shell to shorten the length of the filter and facilitate layout, with one ash hopper.

For the ontology, we conduct strength design with unfavorable load combinations in the design; Made of Q23 sheet metal.

The filter bag specification is a 260 series, and the upper end of the filter bag adopts a rubber pad pressure plate, which has good sealing performance and is easy to replace. Each filter bag is equipped with a carbon steel bag cage.

The controller adopts two forms of control: automatic and manual exchange.

For the operation of the bag filter, each dust collector is also equipped with one filter bag leak detection hole.

Dust containing gas enters the upper space of the filter chamber in a tangential direction. Under the centrifugal force of large and condensed dust particles, small particles in the ash hopper spin down along the cylinder wall and disperse in the gaps between the filter chamber bags, which are blocked by the bags. Purified air is collected in the clean room through the bag wall and the filter bag guide on the flower plate, and is sucked in by the ventilation fan and discharged into the atmosphere.

The characteristics of bag filter in stone material factory:

1. The flow pattern design of the shell cyclone dust collector can play a local cyclone effect and reduce the load on the filter bag. The shape of the cylindrical arch is uniformly stressed.

2. The equipment adopts the built-in high-pressure fan for reverse blowing and cleaning, which is not limited by the gas source conditions in the usage situation. It has fewer vulnerable parts, simple maintenance, and operation, overcoming the drawbacks of compressed air pulse cleaning. The anti blowing effect distance is large, and long filter bags can be used to fully utilize space and occupy a small area.

3. The bag filter in the stone factory adopts trapezoidal flat bags with large amplitude, which can shake off accumulated dust with just one vibration, which is beneficial for improving the service life of the filter bags.

4. The bag filter in the stone factory automatically controls the rotary reverse blowing for dust cleaning, and adjusts the cleaning cycle automatically depending on the low inlet. Compared to the timing control method, it is more reasonable.
