High Efficiency of Hydrogen Plant By Water Electrolysis
1. Introduction
Hydrogen production by water electrolysis has the advantages of flexible application site, high product purity, large operation flexibility, simple equipment and high degree of automation, and is widely used in industrial, commercial and civil fields. In response to the country's low-carbon and green energy, hydrogen production by water electrolysis is widely deployed in places for green energy such as photovoltaic and wind power
2. Technical Features
•Sealing gasket adopts new polymer material to ensure the sealing performance of the electrolytic cell.
•The electrolyzer uses asbestos-free diaphragm cloth, which can reduce energy consumption, is green and environmentally friendly, has no carcinogens, and does not need to clean the filter.
• Perfect interlock alarm function.
•Adopt independent PLC control, with fault self-recovery function.
•Small footprint and compact equipment layout.
• Stable operation, uninterrupted throughout the year.
•Highly automated, enabling unmanned management on site.
• Under 30%-100% flow rate, the load can be adjusted freely, and the operation is safe and stable.
• The equipment has long service life and high reliability.
3. Brief Introduction of Process Flow
The raw water (pure water) in the raw water tank is injected into the hydrogen-oxygen scrubber through the water supply pump, and the lye in the gas is washed and then enters the hydrogen-oxygen separator. The electrolyzer produces hydrogen and oxygen under DC electrolysis. Hydrogen and oxygen are separated, washed and cooled by the hydrogen-oxygen separator, and the water separated by the water inlet separator is discharged through the drain pipe. Oxygen is output by the regulating valve through the oxygen outlet pipeline, and the user can choose to empty it or store it for use according to the usage situation. The production of hydrogen is regulated from the outlet of the gas-water separator through a regulating valve.
The make-up water for the water-sealed tank is the cooling water from the utilities. The rectifier cabinet is cooled by thyristors.
The whole set of hydrogen production system is controlled by PLC program to run fully automatically, stop automatically, detect and control automatically. It has control functions such as alarms and chains at all levels, and realizes the automation level of one-button start. With manual operation function. When the PLC fails, the system can be operated manually to ensure the continuous production of hydrogen by the system.
