印染废水热能回收技术的应用

Application of heat energy recovery technology in printing and dyeing wastewater

针对当前印染企业高温废水排放,造成大量废水热能浪费,给污水处理带来不必要的成本。多机台的废水集中进行热能回收,最大限度利用废水的热能,有效降低排放废水的温度,热能回收效率可达80%。热能的循环利用降低生产过程成本消耗,实现染整行业节能减排、绿色环保生产的目的。

Heat energy waste and unnecessary cost of sewage treatment were caused by draining high temperature waste water from printing and dyeing factories. Multiplex platforms were used for heat energy recovery in maximum, which not only efficiently reduced the temperature of waste water, but also promoted the recovery heat energy to 80%. The heat energy recycling declined the cost efficiently during production, also achieved the purpose of energy saving and green production of the whole dyeing field.
