1Ton Electric Furnace Dust Collector
1Ton Electric Furnace Dust CollectorThe device system is as follows: Under the suction of the centrifugal main fan, the flue gas from the industrial silicon production electric furnace is led out from the semi - enclosed electric furnace. Along the flue, it first enters the cyclone dust collector. Coarse particles and sparks are separated and settled in the ash hopper and discharged through the discharger. After being discharged from the outlet of the cyclone dust collector, the ultra - fine dust and dust - containing gas enter a heat exchanger. The flue gas temperature is reduced by air cooling. Then other dust particles rise with the airflow and enter each bag chamber of the bag - type dust collector. After being filtered by the filter bags, the dust is retained outside the filter bags. The purified gas enters the box through the filter bags, and then enters the centrifugal main fan through the bag mouth and the air outlet of the upper box (clean air chamber) and is discharged into the chimney and then into the atmosphere. The dust in the ash hopper is discharged periodically or continuously by the ash discharge system.
1Ton Electric Furnace Dust CollectorPrinciple:
Under the suction of the centrifugal main fan, the flue gas from the industrial silicon production electric furnace is led out from the semi - enclosed electric furnace. Along the flue, it first enters a secondary combustion chamber and a pre - dust collector. Coarse particles and sparks are separated, and the flue dust is fully combusted. The flue gas after combustion enters a heat exchanger to reduce the flue gas temperature. Then it is sent into the bag - type dust collector by the fan. The dust is retained in the filter bags. The purified flue gas is discharged into the atmosphere through the top of the dust collector. The fine powder under the ash hopper is bagged manually or mechanically and output.
The electric furnace dust collector is designed with different configuration lists according to the different dust properties of the smelting materials.,The problems existing in most manufacturers are that the electric furnace structural parameters do not match. High - voltage, high - yield, and over - load wrong power consumption cause serious arcing. The proportioning is not strict, and improper smelting methods cause serious arcing. Industrial silicon smelting is carried out continuously under the submerged arc state of the electric furnace. In operation, it is necessary to carry out closed - arc operation, add materials and poke the furnace in a timely manner, and adjust the ratio of the furnace charge resistance to the current and voltage. The advantages of closed - arc operation are: the charge layer structure in the furnace can form a complete system, and the furnace charge sinks in turn; the arc light does not expose, and the high furnace temperature is maintained; the electrode consumption is balanced and stable, and electrode breakage is avoided; the material surface temperature is relatively low, and the utilization rate of the electric furnace equipment is improved; the dust volume is relatively small, which can provide a better environment for the electric furnace operation. Whether the electric furnace capacity is large or small, closed - arc operation can be achieved. This is an important measure to reduce the flue gas volume, improve the silicon recovery rate, reduce consumption, and solve the vicious circle between operation and flue dust purification.
The flue gas treatment of electric furnaces has always been a major problem for domestic ferrosilicon enterprises. For many years, Chinese environmental protection technicians have done a lot of work and tried various dust removal technologies, but the dust removal effect has not been very good.2000 In August8, after detailed on - site investigation and research, the main technical personnel of our company, Cangzhou Jinding Environmental Protection Equipment Co., Ltd., designed theLCDM series of low - pressure long - bag pulse bag dust collectors for the characteristics of dust - containing waste gas from semi - closed calcium carbide furnaces. It was successfully built and put into operation in the calcium carbide branch of a chemical general factory in Shaanxi on an8000KVA semi - closed calcium carbide furnace, achieving good results. This dust collector has been in operation ever since, with very stable usage. The dust emission has always been lower than the national emission standard, and the average service life of the filter bags of the electric furnace dust collector has reached more than one year.
