Embodiment Construction
[0019] The outstanding feature of the present invention is that gaseous ammonia is used instead of liquid ammonia as the supplementary source of the inlet flow of the centrifugal ammonia compressor to prevent turbulence. The specific technical means are: lead a bypass pipeline from the outlet pipeline of the ammonia compressor to communicate with the inlet of the ammonia compressor, and feed the compressed ammonia gas back to the inlet of the ammonia compressor.
[0020] The bypass pipeline can be drawn from the outlet 2 of the first stage of the ammonia compressor, or from the outlet of the second stage 4 or the third stage 5 of the ammonia compressor, but it is better to lead from the outlet of the third stage cooler 5, as shown in Figure 1. In this way, gas ammonia can be provided to the inlet of the ammonia compressor, and the liquefied ammonia in the liquid ammonia storage tank 8 can not be used as the flow replenishment source of the inlet of the ammonia compressor, so as...
