我厂辉钼精矿(MoS_2)焙烧过程中产生大量含 SO_2约1%的废气。多年来,辉钼精矿是在八层焙烧炉中进行氧化焙烧。焙烧温度为650℃,燃料是发生炉煤气。废气中携带大量烟尘,经集尘斗、干式电除尘器、洗涤塔和湿式电除尘器等除尘系统。含硫的气体除在炉顶稍有损失外,经湿式除尘后烟气中所含少量的 SO_2溶解于水中。被吸收后之烟气中含 SO_2为0.8～1%,含尘量几十毫克/标准立方米,温度为t80～200℃,经风机送
In our plant molybdenum molybdenum concentrate (MoS_2), a large amount of exhaust gas containing about 1% SO 2 is generated during the roasting process. Over the years, molybdenum concentrate is roasted in an eight-layer roaster. The calcination temperature is 650 ° C and the fuel is producer gas. The exhaust gas carries a large amount of smoke and dust, the dust collection bucket, dry electrostatic precipitator, scrubber and wet electrostatic precipitator dust removal system. Sulfur gas in addition to the top of the furnace a slight loss, the wet dust after a small amount of SO2 dissolved in water dissolved in water. After the absorption of flue gas containing SO2 0.8 ~ 1%, dust content of dozens of mg / standard cubic meters, the temperature of t80 ~ 200 ℃, the fan to send
