据不完全调查,北京市供热系统冷凝水回收率只有3.6%～19.3%,大量高品位的水被白白放掉。为此北京节能技术服务中心研制开发了 JLH 型冷凝水回收装置,近日通过市经委、市节能办主持验收。该冷凝水回收装置是用水——水喷射器前置于水泵入口,用喷射扬程代替与水泵入口水温相关的灌注压头,防止水泵工作时产生汽蚀,解决了水泵吸入口处汽堵的难题。该装置先后经同仁堂制药厂、西郊乳品厂
According to incomplete investigations, the recovery rate of condensate in Beijing’s heating system is only 3.6% to 19.3%, and a large amount of high-grade water is let out. For this purpose, the Beijing Energy Saving Technology Service Center has developed a JLH-type condensate recovery device, which was recently approved by the Municipal Economic Commission and the Municipal Energy Conservation Office. The condensate recovery device is a water-water injector placed at the entrance of the pump, and the injection head is used instead of the perfusion head related to the water temperature at the inlet of the pump to prevent cavitation from occurring during operation of the pump, thereby solving the problem of vapor blockage at the suction inlet of the pump. . The device has passed Tongrentang Pharmaceutical Factory and Xijiao Dairy Factory
