1存在问题河北石家庄双联化工有限责任公司(以下简称双联公司)原设计2套变换系统与锅炉上水换热流程:第2水加热器管内热水与管间除盐水换热,除盐水由25~30 t升温至50~60弋作为锅炉上水,饱和塔出口热水经第2水加热器,温度由90工左右降为65~70 t进热水塔;在热水塔内,热水与变换气逆流接触回收变换气中余热,热水由65~70“€被加热至110 t左右进热水泵,变换
1 existing problems Shijiazhuang Shuanglian Chemical Co., Ltd. (hereinafter referred to as the Shuanglian company) originally designed two sets of conversion system and boiler Sheung Shui heat transfer process: the second water heater pipe hot water and pipe between the desalted water heat exchanger, demineralized water From 25 to 30 t warmed to 50 ~ 60 Yi as the boiler water, hot water saturation tower outlet by the second water heater, the temperature from about 90 workers down to 65 ~ 70 t into the hot water tower; in the hot water tower, Hot water and the conversion gas countercurrent contact recovery of conversion gas waste heat, hot water from 65 ~ 70 ”€ is heated to about 110 t into the hot water pump, change
