Comprehensive treatment device for water electrolysis hydrogen production equipment

Abstract

The invention relates to a comprehensive treatment device for hydrogen manufacturing equipment through water electrolysis and belongs to the technical field of hydrogen or oxygen electrolysed water. A gas inlet is formed in the bottom of a tank body; the outlet of a water replenishing overflow pipe extends to the bottom of a gas-liquid separator; a replenishing water inlet communicated with outside is formed in the lower part of the tank body; a backflow component is arranged in the middle of the tank body; a drop capturing net is arranged at the upper part of the tank body. The comprehensive treatment device for the hydrogen manufacturing equipment through water electrolysis is integrated and replenished on the basis of the prior art, multiple steps in the hydrogen manufacturing process through water electrolysis are integrated, and the comprehensive treatment device, which can be used for cleaning, and cooling gas and replenishing water to a system during the hydrogen manufacturing process through water electrolysis, is provided, so that integration of multiple functions is realized, the total occupied area of the hydrogen manufacturing equipment through water electrolysis is reduced, the cost is reduced, and the whole utilization ratio of the device is increased.

Description

technical field [0001] The invention relates to a treatment device for hydrogen production, which belongs to the technical field of hydrogen or oxygen electrolysis water. Background technique [0002] The general technological process of hydrogen production by water electrolysis is: use 25-30% potassium hydroxide or sodium hydroxide aqueous solution as the electrolyte, and the electrolyzer works at 80-90 °C. When the electrolysis system is in normal operation, the industrial soft water is produced by the pure water device and sent to the pure water tank, and then input to the lye system through the replenishment pump to supplement the water consumed by electrolysis. Water is electrolyzed into H in the electrolyzer 2 with O 2 , and enter the gas-liquid treatment device together with the lye that has not been electrolyzed, and then perform gas-liquid separation in the gas-liquid separator, and the separated gas passes through the gas scrubber and gas cooler. In this process...

Problems solved by technology

[0005] In addition, during the operation of the electrolytic equipment, it is often necessary to replenish water. Since the normal working temperature in the electrolytic cell is about 85°C, it is necessary to preheat the replenishing water before adding it to the electrolytic cell, otherwise it will affect the working temperature of the electrolytic cell. Reduce the quality of hydrogen produced

[0006] Therefore, from an overall point of view, water electrolysis hydrogen production equipment is indispensable for gas cooling, dealkalization, and water replenishment. Large scale brings a series of problems such as land occupation, maintenance and economic benefits
