2.0-3.2m 两段式发生炉煤气站 返回列表页

两段式冷煤气站是由两段式煤气发生炉、电捕焦油器、间接冷却器、电捕轻油器、风冷器及煤气加压机组成。此工艺为目前zui为环保的全间冷工艺。下段煤气利用风冷器与空气热交换进行冷却后，与上段煤气混合后利用间冷器与水进行间接热交换。实行全间接冷却，污水集中统一处理，真正实现污水*。规格有Φ2.0、Φ2.6、Φ3.0、Φ3.2。

      Two-stage cold coal gas station consists of two-stage coal gasifier, electric detarrer, indirect cooler, electric deoiler, air cooler and coal gas pressure adder. This technology is the most environmental protection entire indirect cooling technology at present. Downstage coal gas is cooled by the heat exchange with air through the air cooler, the mix with the upstage coal gas in the indirect cooler, process the indirect heat exchange with water . it is entire indirect cooling , the polluted water is treated together, and really inplement no polluted water discharging. The specs includeΦ2.0、Φ2.6、Φ3.0、Φ3.2.
