Pulse Bag Type Dust Collector

Pulse Bag Type Dust Collector

The GMC series pulse bag type dust collector adopts advanced Pulse-Jet dust removal and cleaning technology to clean the dust attached to the surface of the filter material. It has strong dust removal ability and high dust removal efficiency, and is particularly suitable for collecting various dry dust or materials. In the field of multi-point dispersed dust control, its cost is low, configuration is flexible, and practical advantages are more obvious.

Overview

The structure of pulse bag type dust collector from top to bottom includes: gas purification chamber, pulse valve, electrical control system, sewage discharge device, compressed air bag, dust removal chamber, ash hopper, ash discharge valve, etc. It has been widely used in material cutting, shredding, grinding, mixing, stirring and other links in industries such as cement, building materials, medicine, chemical industry, mining and metallurgy, woodworking, solid waste disposal, etc.

Its working principle is: After the dust containing gas enters the dust collector through the air inlet, a portion of the coarser dust particles fall into the ash hopper due to inertia, collision, natural sedimentation, and other reasons. Most of the dust enters from the bottom of the dust removal room with the airflow. Due to the blocking effect of the filter bag/cartridge, the dust is blocked and left on the outer surface of the filter bag/cartridge, gradually covering and stacking to form a dust layer, further improving the filtering ability of the filter bag/cartridge for subsequent dust. Guided by the airflow of the induced draft fan (ID fan), the dust gas enters the purification chamber after being purified by the filter bag/cartridge, and is then discharged into the atmosphere through the air outlet, achieving the goals of dust control and particle recovery.

When the dust on the surface of the filter bag/cartridge continues to increase and the equipment resistance rises to the set value, the time relay (or micro differential pressure controller) outputs a signal, and the pulse control instrument begins to work. Each pulse valve is opened one by one, and compressed air is sprayed through the blowing port to clean the filter bag/cartridge. Under the action of reverse airflow, the filter bag/cartridge rapidly expands and contracts, and the dust attached to the surface of the filter bag/cartridge quickly detaches from the filter bag/cartridge and falls into the ash hopper. The collected dust is discharged by the ash discharge valve. After the spraying and cleaning of the dust is completed, the dust collector resumes normal operation. This cycle is repeated to achieve continuous filtration and purification of dusty gas.

Features

  • The air inlet and air outlet are integrated and separated by inclined partitions, avoiding direct dust erosion of the bag, reducing the concentration of dust containing gases, and extending the service life of the filter bag and pulse valve.

  • The sealing materials are all made of high-temperature resistant materials, and the filter bag can achieve various film covering, effectively solving problems such as high temperature, adhesion, condensation, etc.

  • The dust cleaning and blowing pipe adopts an extended type, which keeps the pulse electromagnetic valve away from high-temperature flue gas and avoids damage to the valve plate of the pulse electromagnetic valve at high temperatures.

  • The dust removal efficiency is generally above 99.6%, and the dust concentration of the gas at the equipment outlet is within 30mg/m3. It has a high classification efficiency for fine dust with sub micron particle sizes.

  • The upper bag extraction method is adopted, and the top cover door is opened when changing bags. After the skeleton is removed, the bag can be changed, improving the operating conditions for changing bags.

  • Adopting an automated control spraying cleaning system to reduce labor costs.
