Features 

     This remover adopts external filtration, down feed operation modes and pulse back-blowing dust removing. The fiberglass needle penetrated filtering material is a newly developed efficient material that can operate at high temperature. It is a new type of high temperature resistant filtering material with reasonable structure and excellent performance. With stable dimension and high strength, this dust remover is not only high temperature resistant, but also corrosion resistant. Besides, it has low filtering resistance for gas and higher dust removing efficiency than fabric filtering materials, reaching 99.9%. Its filtration rate is almost as twice that of fabric filtering materials.

    This equipment can undergo long-term highly efficient operation under the condition of high dust density at the temperature below 260°C.  Electric controller is controlled by programmable controller regularly or on certain pressure. The glass fiber filter bag has a length of 2~12m and a diameter of 130 mm.

Application scope

     It can be widely used in wasted gas purification and material recovery in cement, power plant, metallurgy and carbon.

Operating principle

    During normal operation, dust air is drown into air inlet manifold under the action of ventilator, then is evenly distributed to each inlet chamber through inlet branch and then is flown into filter bag. Large quantity of dust is retained on the filter bag, in which air stream passes through. Purified air stream flows into bag chamber and then is discharged into the atmosphere through the smoke pipe. 
    With the increase of dust attached on the surface of the filter bag and growing resistance, regular dust cleaning is needed to make the resistance fall to specified limit so that the dust remover can enter into normal operation. Dust cleaning is mainly completed by high pressure gas storage bag, solenoid valve, blowing pipe and dust removing controlling mechanism. Firstly, solenoid valve is automatically turned on by the operation system rapidly; high pressure air back blows via blowing pipe to make dust attached on the filter bag shake into the dust hopper. And then dust cleaning is finished after solenoid valve is turned off. Filter bag is resumed to filtering state. Other solenoid valves are turned on by the operations system to conduct dust cleaning on other filter bags. Dust cleaning recycling goes through all the filter bags and the dust removing effect is achieved. Dust remover completely switches to filtering state and dust in the hopper is discharged to conveyor from ash valve at the bottom.
