一、电炉除尘系统能耗现状目前,国内电弧炉除尘风机能耗高是普遍存在的问题。因为除尘风机从开炉到停炉一直在额定转速下无控制地运转。且风机容量又是按照氧化期最大排烟量选定的;同时大中型风机在设计时还有约10％的余量包括在计算值内。这就使熔化期、还原期和冶炼间隔期,风机、电机的容量相对偏大很多。
First, the electric furnace dust removal system status of energy consumption At present, the domestic energy consumption of electric arc furnace dust fan is a common problem. Because the dedusting fan has been operating uncontrollably at rated speed from open to shutdown. And the fan capacity is selected in accordance with the maximum amount of smoke during the oxidation period; while medium and large fans in the design of about 10% of the margin included in the calculation. This makes the melting period, the reduction period and smelting interval, fan, motor capacity is relatively large capacity.
