Boiler bag dust collector
This technical achievement has advanced and reasonable design, simple structure, low investment, low energy-saving operation cost, stable, efficient and reliable operation, large air volume and easy operation. The export dust content is lower than the national environmental protection emission standards, and has high economic, environmental and social benefits. It is the current ideal dust removal equipment and is used to purify large air volume smoke and small air volume smoke in metallurgy, machinery, chemical industry, building materials and other industries. , has broad promotion and application prospects. Boiler bag dust collector
Characteristics:
The equipment has a compartment structure, with compartments of different specifications. The combination is flexible and convenient, and it is suitable for boilers of different sizes and layouts of various sites.
Under normal circumstances, the service life of filter bags can generally reach more than two to three years.
Using three-state dust cleaning, the dust cleaning effect is good and the dust collector operation resistance is low. Due to long-term experiments and research on the injection system, we have mastered the design methods of different filter bag combinations and different filter bag lengths.
Use various types of main pipes such as wedge-shaped and stepped entrances. Make the air flow in each chamber evenly distributed.
The ash hopper and air duct adopt advanced diversion devices, which can reduce system resistance and extend the service life of filter bags.
Selecting high-quality filter bag cage bones produced by special automated equipment can ensure that the bag cage is flat, smooth and has good dimensional accuracy, thereby extending the service life of the filter bag.
Working principle of boiler bag dust collector
Under the action of the induced draft fan, the dusty flue gas flows from the outlet of the boiler preheater through the flue system and first enters the air inlet main pipe of the dust collector. (wedge-shaped or stepped air duct), and then use the diversion device in the air inlet main pipe to make the air inlet volume uniform and then enter the ash hopper of each room through the air inlet regulating valve. The coarse dust particles settle to the bottom of the ash hopper, and the fine dust particles turn upward with the air flow. After entering the filter chamber, the dust is blocked on the surface of the filter bag. The purified gas enters the clean room through the filter bag opening (the flower plate hole), is discharged from the air outlet through the exhaust valve to the air outlet main pipe, and then is exhausted through the induced draft fan. To the atmosphere.
The boiler dust collector
adopts three-state offline pulse dust cleaning, which is automatically controlled by the dust collector. As the dust collector operates, the dust retained on the surface of the filter bag increases, and the gas resistance increases accordingly. When the resistance increases When the value reaches the set value, each chamber can be cyclically cleaned according to the set method (pressure difference control, time control, manual control). The dust collector starts to stop the air in different rooms for offline pulse injection dust cleaning. According to the set pressure difference control program, the programmable electronic controller first closes the exhaust valve of the first room room by room, so that the filter bag in the room is in a state of no air flow, and then opens the pulse valve row by row to use low-pressure compressed air to filter the filter bags. The bags are cleaned by pulse injection, and the cleared dust is collected in the ash hopper and discharged into the ash conveying system below through the rotary ash discharge valve. After the filter bag in this chamber is cleaned, open the exhaust valve to restore the filtering state of this chamber, and then clean the next chamber one by one. There is a regulating valve at the air inlet of each room, and an air stop valve at the air outlet, so each room can automatically operate independently to achieve non-stop maintenance. The automatic control program switches to timing control after determining the cleaning cycle and the interval between two cleanings.
