Efficient molecular sieve regeneration device

The utility model discloses an efficient molecular sieve regeneration device which comprises a molecular sieve tower A and a molecular sieve tower B. An air inlet pipe network and an air outlet pipe network are respectively communicated and connected between two ends of the molecular sieve tower A and the molecular sieve tower B. The efficient molecular sieve regeneration device further comprises a dryer, a heat exchanger, a steam pipeline, an air inlet pipeline, an air return pipeline, a nitrogen inlet pipe and a nitrogen outlet pipe, the nitrogen inlet pipe is additionally arranged, nitrogen in a nitrogen production workshop is introduced into the dryer to be dried through the nitrogen inlet pipe, the dried nitrogen enters the air inlet pipe network through the air inlet pipeline, nitrogen cold blowing can be carried out on the molecular sieve tower, and due to the fact that the nitrogen does not contain water and is good in cold blowing effect, the dew point temperature is further reduced; compressed air d
