Evaporative cooling medium self-circulation full-immersion type water electrolysis hydrogen production system and using method

Abstract

The invention discloses an evaporative cooling medium self-circulation full-immersion type water electrolysis hydrogen production system, and relates to the technical field of hydrogen energy. The system comprises a vertical array hydrogen production unit and an evaporative cooling medium supplementing system, wherein the vertical array hydrogen production unit sequentially comprises an electrolytic bath, a gas-liquid separator, a drying and purifying device and a hydrogen pressurizing device from bottom to top; the evaporative cooling medium supplementing system comprises a sealed container, a condensing coil, a liquid collecting tray, a gas storage tank and a solution tank; the hydrogen pressurizing device is connected with the gas storage tank; and an evaporative cooling medium submerging the vertical array hydrogen production unit and the gas storage tank is arranged in the sealed container. The direct evaporative cooling technology and the water electrolysis hydrogen production system are combined, heat is taken away through gas-liquid phase change self-circulation of an evaporative cooling medium, additional kinetic energy does not need to be provided, the heat exchange efficiency in the operation process is high, and the system can adapt to various working conditions. The invention further relates to a using method of the evaporative cooling medium self-circulation full-immersion type water electrolysis hydrogen production system.

Description

Technical field [0001] Technical Field The present invention relates to hydrogen, and more particularly it is a circulating cooling medium evaporated from total immersion in water electrolysis system. The present invention further relates to such an evaporative cooling medium from the circulation using the total immersion method is water electrolysis system. Background technique [0002] Hydrogen as a focus of future research directions of clean energy, with hydrogen production technology has matured and improved, hydrogen production capacity has gradually increased, leading to the space occupied by hydrogen plant is gradually increased, the heat generated during hydrogen production and more huge. Conventional open conventional high heat radiation effect cooling (air cooling) to ambient environment requirements, and heat dissipation effect is not ideal; The water electrolysis process requirements, the corresponding device must be controlled within a certain temperature range, sho...

AI Technical Summary

Problems solved by technology

In the past, the conventional open cooling effect (air cooling) has high requirements on the surrounding environment, and the heat dissipation effect is not ideal; according to the requirements of the water electrolysis hydrogen production process, the temperature of the corresponding equipment must be controlled within a certain range and must not exceed the specified value ; and hydrogen is a dangerous gas that is flammable and explosive. It is easy to cause accidents when encountering high temperature in an aerobic environment. The heat dissipation problem in the hydrogen production process needs to be paid attention to.
