热回收式液氮蒸发系统技术方案

一种热回收式液氮蒸发系统。为了克服液氮蒸发装置存在的安全性能差、热回收效率低，导致液氮蒸发器与液氮泵设备不匹配的不足，本发明专利技术热交换装置由雾化装置(1)和热交换装置(2)组成，雾化装置(1)的喷嘴(5)与热交换装置(2)的热交换室(11)内腔相通；雾化装置(1)的压缩空气管(3)与喷管(6)固定连接，喷管(6)的前端为喷嘴(5)，喷嘴(5)的喷口面积小于喷管(6)的横截面积；虹吸管(7)的一端与压缩空气管(3)连通，另一端位于水箱(9)内；热交换装置(2)的热交换室(11)上端有排气孔(10)。其有益效果是结构合理，能够有效提高热交换装置的热容，提高热效率；安全可靠，便于调控。

Heat recovery type liquid nitrogen evaporation system

Heat recovery type liquid nitrogen evaporation system. In order to overcome the safety performance in the presence of liquid nitrogen evaporation device, the heat recovery efficiency is low, which leads to the deficiency of the liquid nitrogen evaporator and liquid nitrogen pump equipment, the invention, the heat exchange device by atomization device (1) and the heat exchange device (2), (1) the nozzle atomization device (5) and (2 heat exchange device) the heat exchange chamber (11) is communicated with the atomization device; (1) the compressed air pipe (3) and (6) the nozzle is fixedly connected with the nozzle (6) is arranged at the front end of the nozzle (5), (5) the nozzle exit area is smaller than the nozzle (6) of the cross-sectional area of the rainbow (7 Straw;) with one end of the compressed air pipe (3) communicated with the other end of the water tank (9); the heat exchange device (2) of the heat exchange chamber (11) is arranged on the upper end of the exhaust hole (10). The utility model has the advantages that the structure is reasonable, the heat capacity of the heat exchange device can be effectively improved, and the heat efficiency is improved; the utility model is safe and reliable, and is convenient for regulation and control.
