余热回收技术改造

日期： 2022-09-21 作者：晟德亿编辑

目前余热回收技术是通过直接加热或者间接换热提取固体、液体、气体中的热值，产生热水、蒸汽满足工艺需求。余热回收的这部分热水、蒸汽节约生产成本、提高了能源利用率。

冷凝水回收闪蒸系统是处理高温冷凝水余热回收技术，蒸汽的一般节能率为8%-16%。苏州晟德亿节能环保科技有限公司可提供具体的技术改造方案。

高温冷凝水密闭回收闪蒸系统余热回收率最高为24%。

换热器余热回收率超过50%。

焓差补偿式扩容净化回收器可以100%的回收高温余热废水。

企业根据实际情况选择不同的系统和设备回收冷凝水的余热。

冷凝水密闭回收闪蒸系统产生的闪蒸汽节约了用能成本，蒸汽品质较高。

焓差补偿式扩容净化回收器需要高压高温蒸汽加热能耗较高，蒸汽品质可满足生产要求不高的企业。

换热器回收的余热相对温度比较低，适用范围较窄。

某造纸公司有4台260吨高温高压流化床锅炉和1台350吨水煤浆锅炉。电站锅炉全年共产832000吨蒸汽，按锅炉连续排污率为2%，连排废水量为156000吨，造纸公司没有对这156000吨连排废水进行节能回收改造，而是通过闪蒸器进行闪蒸回收一部分低压闪蒸蒸汽用于锅炉除氧器除氧。由于这种传统的闪蒸器对锅炉连续排污水的回收回收率低，仅达到15%，每小时约有15吨左右的连排废水被排入地沟造成浪费。苏州晟德亿节能环保科技有限公司对五台锅炉的连续排污水实施了余热回收节能改造，并达到了预期目标。具体余热回收节能改造方案可在线咨询或留言。
