Method for driving working agent out of a rich working agent solution

摘要

Method and device for driving out working agent from a rich working agent solution for operating absorption refrigerating machines (absorption cold generators) and/or absorption heat pumps, in the case of which the rich working agent solution in a container 9 is guided in a thin film into heat exchange tubes 10 and heated in the process. The working agent degassed thereby and the solution deprived of working agent are collected. The gas stream is guided in a spray section 4 over the inflowing rich working agent. In order to avoid mutual hindrance of the rich working medium solution flowing into the heat exchange tubes 10 and the stream, emanating from said solution, of gaseous working agent, a gas lock 5 is provided between the inlet 2 of the rich working agent and the inflow regions of the heat exchange tubes 10. Also provided is a bypass line 8 leading from the outflow ends of the heat exchange tubes to a space 13 situated between the gas lock and the spray section. This provides a direct-current guidance of the working agent solution and of the working agent degassing from the latter in the region of the heat exchange tubes. IMAGE
