Description
Technical field
The utility model relates to a kind of equipment, especially a kind of arc furnace equipment.
Background technology
In production smelting process, all can apply to arc furnace equipment, production smelting process is three phases substantially: i.e. charge period, smelting phase, the tapping phase; Wherein, to smelt stage flue gas generating capacity maximum, in flue gas, ultrafine dust content is high.And in overall process, the main master that changes to operating (duration of heat, power supply, batch) duration of heat of the size of exhaust gas volumn.
Therefore, a successful dust pelletizing system should be that flue gas trapping rate is high, and concentration of emission is up to standard, and (comprising the free dust amount of operating surface), system operation energy consumption was low, reduced investment.The mode of flue gas trapping is the first link of dust pelletizing system, the height of capture rate is the main aspect of weighing dust pelletizing system quality, and the height of capture rate is not merely to select that fume trap cover, to consider the unfavorable factor that the crossflow in workshop causes guiding flue gas simultaneously.
According to domestic and international smelting dedusting technology present situation, Trapping ways is divided in stove two kinds of smoke evacuations and the outer smoke evacuation of stove simply, due to reinforced and tapping, implements smoke evacuation in stove, comparatively complicated, therefore, selects stove to discharge fume outward and traps the flue dust in each stage.
Domestic middle-size and small-size smelting furnace is in charge period, smelting phase, tapping phase; Wherein, to smelt stage flue gas generating capacity maximum, in flue gas, ultrafine dust content flue gas paroxysmal high thereby that produce is strong, and exhaust gas volumn fluctuation is large, distributes a little manyly, and collection difficulty is high.The general fume amount of smelting shop is large, temperature is high, noise is large, and the environment of production work is very severe.The pollution control of domestic iron and steel has been carried out for many years, but still has more problem, and even some governing system is in paralyzed state so far.Its chief reason is that smoke catching efficiency is low, the poor reliability of deduster own, not good operation and the smelting that affects stove of technological design.Although some designs have realized good smoke catching effect, system and device capacity is very huge, and system floor space is large, cost of equipment costliness, and also operating cost is also high.Therefore current, obtain that regulation effect is good, reliability is high, reduced investment, cleanse system for soot that operating cost is low are middle-size and small-size smelting enterprise in the urgent need to.
At present, conventional dust collection method has dry method dust and wet dedusting, and dry method dust can be avoided unnecessary secondary pollution, a large amount of useful dust of recoverable in addition, and the pollution problem that current dry method bag dedusting technology can solve dust completely.Compared with wet dedusting, dry dedusting technology has more reliability and economy, and fault is few, and Maintenance and Repair are also more convenient.
The dust-collecting fume hood that existing Dedusting of EAF adopts is roughly divided into: semi-hermetic type mobile cover, workshop roof cover, portable top-draught hood, semi-hermetic type mobile cover, although dust removing effects is better, but can not dirt source is completely airtight, be subject to extraneous airflow influence can cause dust excessive, the design cost of workshop roof cover and portable top-draught hood is all higher;
The domestic bag dust collector for electric furnace arrangement for producing steel mainly contains back-blowing bag duster and pulse bag deduster, all belonging to mature technology, is also comparative maturity although back-blowing bag duster technology is applied to electric stove dust, and its ash-removal effect is poor, filtration velocity can not be too high, and therefore equipment volume is huge.In recent years along with the continuous progress of filtering material technology, the mechanical property (as wear-resisting, folding quality) of material is more advantageous, and can keep good stability in high temperature and chemical attack atmosphere, can adopt the mode of high energy pulse deashing simultaneously, the effect of deashing is greatly improved, gas permeability also improves greatly, and more than filtration velocity can reach 2.5m/min conventionally, and discharge greatly reduces.Compared with adopting the back-blowing deduster of fabric filtrate, the volume of pulse dust collector greatly declines, and general floor space can reduce 1/2, and overall cost and operating cost also reduce greatly, and life-span of the filter bag generally reaches more than 1 year.
