Abstract

The invention discloses a water electrolysis hydrogen production system with integrated electrolyte heating and cooling functions, the system comprises an electrolytic bath, a hydrogen tank and an oxygen tank connected with the electrolytic bath, a heat exchanger connected with the hydrogen tank and the oxygen tank, a cooling water inlet and a cooling water outlet connected with the heat exchanger, and a circulating pump arranged between the electrolytic bath and the heat exchanger, a heating cavity is formed in the heat exchanger, and a heater and a temperature sensor are arranged in the heating cavity. The water electrolysis hydrogen production system with the integrated electrolyte heating and cooling functions is reasonable in structural design, and under the condition that an original system is not changed, the cold-heat exchanger is slightly improved, and the heating cavity part is additionally arranged, so that the following purposes can be achieved: firstly, the cold start time of hydrogen production equipment is greatly shortened; secondly, the time for producing qualified hydrogen by the hydrogen production equipment is shortened; and thirdly, the energy consumption of hydrogen production equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of water electrolysis hydrogen production equipment, in particular to a water electrolysis hydrogen production system with integrated functions of heating and cooling electrolyte. Background technique [0002] In the process of water electrolysis, the electrolyte in the electrolyzer is the medium participating in the electrolysis. The temperature of the electrolyte is the key to ensure the quality of hydrogen and oxygen produced by electrolysis. When the electrolyte temperature reaches 80°C-85°C, the purity indicators of hydrogen and oxygen are the best. At the same time, the voltage of the cell participating in the electrolysis is also the smallest, and the corresponding energy consumption for hydrogen production is also the smallest. [0003] Usually, the hydrogen production equipment starts to work in a cold state (that is, the electrolyte is at normal temperature), and the electrolytic current gradually...
