Title:
HYDROGEN PRODUCTION APPARATUS AND METHOD FOR CONTROLLING TEMPERATURE OF ELECTROLYTIC BATH OF HYDROGEN PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/116015
Kind Code:
A1
Abstract:
The present disclosure relates to a hydrogen production apparatus and a method for controlling the temperature of an electrolytic bath of the hydrogen production apparatus. The hydrogen production apparatus comprises a centralized cooling device, wherein the centralized cooling device comprises a heat exchange water tank and a cooling water tank which are in communication with each other, a heat preservation liquid is stored in the heat exchange water tank, and the centralized cooling device is configured to turn a backflow liquid into a cooling liquid after passing through the heat exchange water tank and the cooling water tank in sequence; and at least one hydrogen production device which is in communication with the centralized cooling device by means of a cooling circulation loop, wherein the cooling circulation loop comprises a liquid inlet flow path and a liquid return flow path, and is configured such that when the hydrogen production device stops working, the liquid inlet flow path is in communication with the heat exchange water tank, so as to enable the heat preservation liquid to enter the hydrogen production device for heat preservation, and when the hydrogen production device works normally, the liquid inlet flow path is in communication with the cooling water tank, so as to enable the cooling liquid to enter the hydrogen production device for cooling. According to the present technical solution, the hydrogen production apparatus and the method for controlling the temperature of the electrolytic bath of the hydrogen production apparatus provided by the present disclosure solve the technical problem of reduced temperature of the electrolytic bath in the apparatus which is shut down during large-scale hydrogen production.
