Wuchang environmental protection WHQC series strong pulse bag filter is a bag filter developed and designed through technological improvement. A combined type strong pulse long bag filter that can meet the requirements of a single machine with a small processing capacity structure and a large air volume atmosphere purification. This model mainly adopts the ash cleaning method of progressive pulse blowing, with high degree of automation (automatic ash removal, ash unloading, automatic temperature control), high purification efficiency, large air volume, good ash removal effect, and long filter bag life. , Easy maintenance, safe and reliable operation.

The Wuchang strong pulse bag filter combines the advantages of the two types of dust collectors: reverse blowing and strong pulse cleaning. It avoids the shortcomings of insufficient strength of traditional reverse blowing and general pulse cleaning and re-adsorption, and the cleaning efficiency is higher. , The advocacy frequency is lower. The product uses an internally flooded strong pulse valve, which reduces the pressure of the blowing air source and the operation energy consumption of the equipment, extends the service life of the long filter bag and the pulse valve, and greatly improves the comprehensive technical performance. The dust collector is mainly composed of automatic control system, upper box body, middle box body, lower ash hopper, air inlet pipe, filter bag and blowing device, ash unloading device, etc.

The working principle of Wuchangqiang pulse bag filter:

The impurity-containing dust gas enters the ash hopper of each compartment from the air inlet pipe of the dust collector, and under the guidance of the ash hopper guide device, the large particles of dust are separated by the interception device and fall directly into the ash hopper, while the finer dust particles enter evenly The middle box body is adsorbed on the outer surface of the filter bag, and the clean gas enters the upper box body through the filter bag, and is discharged into the atmosphere through each offline valve and exhaust pipe. As the filtering conditions progress, the dust on the filter bag accumulates more and more. When the equipment resistance reaches the limited resistance value, the cleaning control device automatically closes a room according to the set value of differential pressure or the set value of cleaning time. After the off-line valve, the electronically controlled strong pulse valve is automatically opened according to the set program to perform blowing. The compressed air is used for instantaneous blowing to increase the pressure in the filter bag, and the dust on the filter bag is shaken off into the ash hopper, and the ash discharge mechanism discharge.

Performance parameters of Wuchangqiang pulse bag filter:

1. The emission concentration of purified air is less than 30mg/Nm3.

2. Purified flue gas desulfurization reaches 92%.

3. The average life of the filter bag is more than 18 months.

4. The operating rate is 100% relative to the main engine.

5. Air volume: 5000-1000000m³/h.

6. Filter area: 500-14000 square meters.

7. Imported dust concentration: <1000.

8. Equipment operating power: 2.2-37kw.

Product features of Wuchangqiang pulse bag filter:

1. Modular production, complete unit combination, free disassembly and assembly of dust removal equipment at all levels of processing capacity.

2. Off-line strong pulse dust cleaning technology for each sub-chamber of the dust collector, with strong dust removal ability, high dust removal efficiency, low emission concentration, low energy consumption, less consumables, less floor space, stable and reliable operation, and high economic benefits;

3. Adopting the design concept of large air volume and low wind speed, the resistance of the dust collector is low, and the efficiency is high;

4. Adopt advanced air flow multiple distribution method to improve the utilization rate of filter area of filter bag and the service life of filter material;

5. The filter bag adopts an in-line matrix arrangement, with compact structure and high space utilization. The upper end of the filter bag adopts a spring ring tensioning form, which has good sealing performance and quick bag change.

Wuchangqiang pulse bag filter is widely used for dust removal and purification and material recovery of various process systems in metallurgy, building materials, machinery, chemical, mining and other industries.
