Abstract

The invention relates to the technical field of water electrolysis hydrogen production equipment, in particular to a water replenishing device and method for a water electrolysis hydrogen production system, and the water replenishing device comprises a water tank, a first valve, a second valve, a third valve, a fourth valve, a pressure stabilizing valve, a water supply pipeline, a pumping device, a water outlet pipeline and at least one water conveying pipeline; by means of the one-to-many design concept, the use number of the pumps can be effectively reduced, the equipment cost is saved, meanwhile, by means of the design scheme that one pump is used and one pump is standby, the problem that the whole water supplementing device cannot be used due to the fact that a single pump goes wrong is effectively solved, the pressure maintaining valves connected in parallel are arranged in the pumping loop, and normal use of the pumps can be guaranteed when backward-stage water supplementing is abnormal. In addition, independent water replenishing of the hydrogen separator and the oxygen separator can be effectively achieved through logic control of the control system, the risk of hydrogen and oxygen mixing is avoided, and the safety and stability of operation of the water replenishing device and the hydrogen production system are improved.

Description

technical field [0001] The invention relates to the technical field of water electrolysis hydrogen production equipment, in particular to a water replenishing device and a water replenishing method for a water electrolysis hydrogen production system. Background technique [0002] Hydrogen energy has attracted everyone's attention due to its advantages of non-polluting combustion and high calorific value. The existing hydrogen production technology by electrolysis of water is relatively mature, and the operation is relatively simple, which is an important means for hydrogen production at present and in the future. Most of the water replenishment devices of the existing hydrogen production equipment adopt a one-to-one replenishment method (one replenishment pump corresponds to a set of frames), and only rely on the control valve and the water pump. The hydrogen and oxygen separator of the hydrogen production system (hydrogen production equipment) Water replenishment is easy t...
