[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] A method for effectively preventing internal leakage of the liquid ammonia water cooler of the present invention comprises the following steps: figure 1 As shown, the ammonia compression device 41, the circulating water cooler 42, and the liquid ammonia tank 43 are sequentially connected in series through pipelines to form the ammonia refrigeration system 4, wherein the ammonia compression device 41 and the liquid ammonia tank 43 are all connected with the low-temperature methanol washing system 5 , the ammonia compression device 41 is now connected to the nitrogen input pipeline 6 provided with the side hand valve 1. After the ammonia refrigeration system 4 is stopped, the water inlet valve 2 and the water outlet valve 3 of the circulating water cooler 42 are opened to avoid completely closing and maintain a constant The circulating water flow rate ensures that...
