【摘要】 30 MVA锰硅矿热炉及其煤气干式净化系统由于技术改造增大冶炼强度提高了锰硅合金的产量,导致煤气最高温度从原设计的650℃提高到950℃,煤气量增加了80％。2004年对煤气净化系统进行了扩容改造,布袋除尘器的处理能力扩大了一倍,并设计开发出蒸发式冷却塔取代原来的空冷管降温系统,占地面积节省一半,降温能力提高了1．52倍。更多还原

【Abstract】 Due to the technical reformation and enlarging the smelting intensity, the set of 30MVA silicon-manganese submerged arc furnace and the dry gas cleaning system has increased the output of silicomanganese, thus, the gas maximum temperature has risen from 650℃to 950℃, and the gas volume has increased by 80%. The dry gas cleaning system had been reconstructed for capacity in 2004, the dust collecting capacity of bag type collector has been doubled, the original air cooling tube was replaced by the newly designed evaporative cooling tower, the floor space requirement has been reduced half, the cooling power has been raised by 152 percent.更多还原
