The main characteristics of the electric furnace dust collector are high cleaning and filtration load, long dust collection bag, small occupied space, low soot blowing pressure, small maintenance workload, easy to change and install the dust filter bag, and compared with the reverse blowing bag dust collector at the same processing air volume, the operating power, occupied area, and equipment weight are significantly reduced in terms of investment. It is mainly used for small dust collection points. This machine uses polyester bags, and the inlet temperature can reach about 120 ℃. In use, it can provide high temperature resistance and filter bag dust removal. The medium furnace flue gas collection system is composed of low-grade mobile dust collection hood, feeding equipment, steel exhaust equipment and dust removal equipment. The low level mobile dust collector covers the operation platform and the steel discharge pit, so that the production process of medium furnace smelting is all carried out in the low level mobile dust collector, realizing the whole process of flue gas capture. During charging, the charging equipment is used for charging, and the charging is carried out several times according to the production needs, which solves the problem that the smoke is difficult to capture when the vehicle is charging; When discharging steel, if the furnace platform is directly discharged into the steel discharge track of the flatbed car of the ladle, and the steel completes the discharge process in the fume hood, which overcomes part of the leaked gas in the local dust hood

The electric furnace will produce a large amount of smoke and dust into the air, seriously polluting the environment and affecting the health of workers. The smelting conditions of the electric furnace equipment are considered in the process design of the electric furnace dust remover of our company. The form of flue gas capture is low umbrella mobile hood. The dusty gas enters the QYMC pulse bag filter through the main flue gas pipe for purification. After purification, the clean gas enters the exhaust pipe through the fan and enters the atmosphere. At the same time, it plays a very good role in preventing air pollution under the normal working conditions of smelting environment

Control method of the ash conveying system of the electric furnace dust remover

(1) Each bin can be offline in a single bin, that is, close the lifting valve and leave the dust collection system. In this case, the furnace will not run the ash cleaning procedure

(2) The automatic control of the ash conveying system adopts timing and manual methods. Timing control: when the dust remover completes 1-2 pulse purging and cleaning cycles (or sets the unloading time), the ash conveying equipment operates once, and the timing interval is adjustable. When ash is discharged, the silo wall vibrator works to make the ash hopper discharge. The on-site control is completed by the machine-side operation box, and the operation status signals of each equipment are provided to the host computer of the main control system

(3) Timing control: select the "Auto" and "Timing" position of the switch. When the system reaches the timing control condition, close 1 # first. The offline valve in room 1 #, the cleaning indicator in room 1 # is on, and the air blowing is started. After the air blowing is completed, open the offline valve in room 1 #, and 1 # starts to work: close the lift valve in room 2 # at an interval of about 20 seconds, and enter the next cycle after completing the cleaning of all compartments in turn. The cycle ends at the beginning of the cleaning process in room 1 #

(4) The ash bucket star type ash unloading valve and the ash bucket wall vibrator of the ash unloading system are linked with the ash unloading system by automatic and on-site control

The electric furnace dust remover is a bag-type dust remover specially designed for the treatment of medium-frequency furnace steelmaking flue gas. The medium-frequency furnace dust collector has small floor area, large processing air volume, fully automatic control, no need for manual supervision and operation, small primary investment, low operating cost, and is the ideal dust removal equipment for small and medium-sized steelmaking enterprises. Even if you snap to 0.5 μ M of fine particles, its dust absorption rate is also very high. As long as the material of the filter bag of the dust collector is good. At present, with the improvement of the production technology of the bag filter and other supporting accessories of the bag-type dust remover, there are more appropriate solutions to the fault factors of the original bag-type dust remover in the use of coal-fired boiler flue gas dust removal. The bag-type dust remover after the transformation of the electric furnace dust remover has become a powerful dust remover, and the electric bag composite dust remover is an important product of our company

Second, the maintenance and management of the electric furnace dust remover is relatively convenient

1. The operation is flexible. When the inlet dust concentration changes greatly, the impact on the dust removal rate will not be great

2. Simple structure, flexible use, easy recovery of dry materials, no sludge disposal

3. The machine body is compact in structure and reasonable in layout. Compared with other dust collectors with the same air volume, it covers a small area and has a large filtering area

4. It can be controlled automatically and manually, and is easy to operate

5. The filter bag structure has good moisture resistance. The bag change adopts split type, which is convenient for maintenance and management

6. It has strong adaptability, can handle different types of dust particles, and the processing capacity can be large or small

7. Less moving parts, good sealing performance, clean box and continuous operation. Split back blowing dust removal< br/>
