| description | The utility model discloses a mounting structure of a process liquid nitrogen pump in a double-tower nitrogen-making air separation device, which comprises a double-tower nitrogen-making air separation device main body comprising a process liquid nitrogen pump main body, and the process liquid nitrogen pump main body is mounted on a pipeline at the top of a main heat exchanger cold box in the double-tower nitrogen-making air separation device main body. The main body of the process liquid nitrogen pump and the main body of the double-tower nitrogen-making air separation device form circulation through a pipeline, liquid nitrogen descends by more than 4 meters from the auxiliary condenser and enters the process liquid nitrogen pump, and after being pressurized by the process liquid nitrogen pump, the liquid nitrogen is conveyed to the main tower by about 4 meters to participate in rectification. The energy consumption required when the process liquid nitrogen pump works is reduced; 2, inlet and outlet pipeline |
