Technical Field

[0002] At present, most large thermal power plants in my country use air-cooled steam turbine units. The commonly used air cooling systems can be mainly divided into three types: mechanical ventilation direct air cooling system, natural ventilation indirect air cooling system and mechanical ventilation indirect air cooling system. However, the air cooling system for power plants is developing in the direction of high parameters and large capacity. It lacks flexibility and adjustability, has a long construction period and occupies a large area, and is difficult to adapt to the cooling needs of the current MW-level water electrolysis hydrogen production system.

[0003] At present, the cooling methods used in the electrolytic water hydrogen production system are mainly air cooling and water cooling. For every 1kg of hydrogen produced, the air cooling method consumes about 11.5L of water, and the water cooling system consumes about 21L of water. Therefore, under the same hydrogen production scale, the electrolytic water hydrogen production system uses dry cooling to save nearly 45% of water compared with water cooling. In order to utilize the relatively abundant renewable energy resources such as photovoltaic power generation and solar thermal power generation in the northwest region, it is planned to construct the electrolytic water hydrogen production method to store this part of solar thermal and photovoltaic power generation in the form of hydrogen energy. At present, electricity prices account for 80% of the operating costs of electrolytic water hydrogen production, and water resources in the region are relatively tight. Water cooling consumes a lot of water and is costly. Summary of the invention
