Abstract
A multi-channel alkaline hydrogen production system is disclosed. Using liquid outlets of a hydrogen alkali treatment unit and an oxygen alkali treatment unit, a circulating alkaline liquid is outputted to an alkaline liquid circulating pump and a controllable channel, and then the circulating alkaline liquid is returned to the negative electrode of an electrolyzer; Thus, a controller can control the amount of produced hydrogen according to the measured current of the electrolyzer, then calculates a corresponding alkaline liquid circulation volume reference value according to the amount of produced hydrogen, and according to the alkaline liquid circulation volume reference value, adjusts the circulation amount of the alkaline liquid of the multi-channel alkaline hydrogen production system and changes the gas purity of the multi-channel alkaline hydrogen production system by controlling the working states of the controllable channels on the two ends of the alkaline liquid circulating pump.
