[0005] To solve the above-mentioned technical problems, this utility model provides a hydrogen recovery and purification device.

The base plate is respectively equipped with the dehydration component and the purification component. The output end of the dehydration component is connected to the input end of the purification component. The purification component purifies the hydrogen through a molecular sieve. In use, the generated hydrogen first enters the dehydration component for dehydration and drying.

After a period of use, the molecular sieve in the purification component is desorbed and regenerated to improve the hydrogen purification efficiency.

[0007] Preferably, the dehydration assembly includes a horizontal plate, a nut, an air inlet pipe, a shell, an air outlet pipe, an air outlet valve, a second circular hole, a filter cylinder, an arc plate, and bolts.
