The utility model discloses a device for controlling the temperature of nitrogen regenerated by a liquid nitrogen wash molecular sieve, which comprises an out-of-boundary normal-temperature low-pressure nitrogen pipeline, and one end of the out-of-boundary normal-temperature low-pressure nitrogen pipeline is connected with the feeding end of a water bath type nitrogen heater through a gas inlet pipeline; the discharge end of the water bath type nitrogen heater is connected with a molecular sieve adsorber through a gas outlet pipeline; the normal-temperature low-pressure nitrogen pipeline outside the boundary area is also connected with the gas outlet pipeline through a subline pipeline; the water bath type nitrogen heating device solves the technical problems that the temperature of liquid nitrogen washing molecular sieve regeneration nitrogen does not reach the standard, so that a program control program cannot automatically run, and other heating modes are not ideal in effect or have risks, and the water ba
