FST-HDC-2000~45000M3/H Stainless Steel Dust Collect:
The high temperature bag filter is a kind of high temperature resistant dust collector, which is suitable for dust removal of boiler and so on. The HDC high temperature bag filter consists of ash hopper, body, filter cloth bag, automatic soot cleaning and injection device and so on.
Principle of operation:
HDC high-temperature bag dust collector consists of ash hopper, box, filter cloth bag, automatic soot-cleaning injection device and so on. When working, the high temperature flue gas enters the dust collector from the air inlet, first meets the inclined partition in the middle of the inlet duct, and the air flow turns downward into the ash hopper. Due to gravity subsidence, the coarse dust particles fall directly into the bottom of the dust hopper, which plays the role of pre-collecting dust. At the same time, the velocity of air flow becomes slower, and the light dust enters the box with the turn of the airflow.
The dust is blocked by the filter of the dust bag and is deposited on the outer surface of the filter bag. The filtered clean gas passes through the filter bag into the upper net air chamber of the box to the air outlet. It is discharged to the atmosphere by the induced fan. The dust deposited on the outer wall of the filter bag is increasing continuously. When the set time or pressure difference is reached, the pulse controller triggers the opening of the pulse solenoid valve in sequence, so that the compressed air in the compressed air bag can be cleaned by the pulse injection of each filter bag through the injection tube.
The filter bag expands rapidly and buffets the dust attached to the outer wall of the filter bag. The dust removed from the filter bag is deposited into the ash hopper and discharged through the ash unloading valve.
1. The air inlet and the outlet are made into one body, separated by slanting separator, the airflow distribution is uniform, the dust-containing gas plays the role of pre-collecting dust and preventing Mars from directly scouring the cloth bag. The dust concentration of dusty gas is reduced and the life of filter bag and pulse valve is prolonged.
2. The filter bag adopts the high temperature resistant cloth bag, such as the sintered stainless steel fiber medium, sintered Fe-Cr-Al fiber Filter Medium, P84 and othe rhigh temperature resistant composite Filter Material, the working temperature is from 200 ℃~1000 ℃.
3. The sealing material of dust collector is high temperature resistant material.
4.The extended type of dust-cleaning spray pipe is adopted to keep the pulse solenoid valve away from the high temperature smoke and to avoid the high temperature damage of the pulse solenoid valve plate.
5. The bag mouth of filter bag adopts elastic expanding ring, sealing performance is good, firm and reliable.
6. The filter bag skeleton is circular, which reduces the friction between the filter bag and the skeleton, prolongs the life of the filter bag, and is convenient to unload the bag.
7. The upper bag extraction method is adopted, the top cover door is opened when the bag is changed, the bag can be changed after the skeleton is taken out, and the operation conditions of the bag exchange are improved.
8. Ash removal control uses timing, fixed pressure, manual control, every other ash cleaning cycle, each filter bag in turn to clean ash.
9. The dust collector is outsourced with rock wool insulation layer to avoid condensation inside the dust collector.
10.The inlet is provided with a bypass valve door to prevent high temperature damage to the cloth bag.
11. Install high temperature alarm device and filter bag leak detection device.
