The invention discloses a water scrubber circulating system and method in a methanol cracking hydrogen production process. The water scrubber circulating system comprises a desalted water tank, a water scrubber, a desalted water pump, a circulating pump, a decomposed gas buffer tank and a regulating valve. Wherein the circulating pump and the water washing tower form a main structure of the circulating system, a self-circulating system is additionally arranged in the water washing tower through the circulating pump, and the leacheate dosage of the water washing tower is greatly increased while the liquid level of the water washing tower and the circulating quantity of an external circulating system are kept unchanged; the liquid level balance in the water washing tower is maintained; and leacheate in the water washing tower is diluted. According to the water scrubber circulating system in the methanol cracking hydrogen production process, residual methanol in reaction gas can be thoroughly removed, and a good
