PREPARATION DEVICE AND PREPARATION METHOD FOR SUPERSATURATED HYDROGEN SOLUTION

摘要

A preparation device (100) and preparation method for a supersaturated hydrogen solution. The preparation device (100) comprises a housing (4) and a hollow fiber membrane group (18). A liquid inlet (42) communicated with a liquid source, a liquid outlet (43), and a gas inlet (44) used for communicating with a hydrogen source are provided on the housing (4); the hollow fiber membrane group (18) comprises a plurality of hollow fiber membrane tubes (19) contained in the housing (4); an inlet end (20) of the hollow fiber membrane group (18) is communicated with the liquid inlet (42), so that liquid can flow in the hollow fiber membrane tubes (19), and hydrogen from the hydrogen source can flow from membrane holes (191) of the hollow fiber membrane tubes (19) into the hollow fiber membrane tubes (19) and can be mixed with the liquid; and an outlet end (23) of the hollow fiber membrane group (18) is communicated with the liquid outlet (43). Hydrogen serving as bubbles in a nano-scale diameter is fully mixed with liquid, the hydrogen concentration and the preparation time of an obtained solution are both superior to the prior art, the preparation efficiency is high, the cost is low, and the application range is wide.
