焕能科技空压机余热回收利用工程

Time:2019-08-14 15:31
一、整体节能规划
合肥万和公司在建厂时,焕能科技就参与其中,通过现场考察,为万和公司进行空压机余热回收改造与量身制定了一套整体节能规划方案。根据不用生产工艺用热水需求,所有需要用热水加热的地方都预铺设了管道,整个布置规划合理,做到了最佳的节能效果。

二、节能改造方案
同时回收4台110kw和1台90kw的寿命空压机润滑油和压缩空气的余热,制造源源不断的热水,利用原来预铺设的管道,将热水输送至各个使用点:



(1)空压机余热回收利用至员工生活用热水(楼顶热水储存箱)



(2)熟化发泡线改造(供给一条10米长的电热水器装配熟化发泡预热炉用热)



(3)铝型材喷粉线节能改造(供给一条喷粉线共3个清洗池的加热)



(4)铝型材清洗池节能改造(供给一条电热水器清洗线共3个池的加热)



(5)空压机余热回收利用工件烘干(供给一条21米长外壳丝和内胆烘干线的加热)


三、节能效益
(1)停用原有的备用清洗池加热锅炉;
(2)原有的烘干线电热棒完全停用,熟化发泡线的电热棒基本停用;
(3)生活使用的热水完全来自空压机余热回收产生的热水。
整个项目投入120万元,每年节省约300万的电加热等费用,投入改造后5个月即回收全部成本。整个系统已经稳定运行将近一年,为合肥万和节省了大量的运营成本。
