Title:
HYDROGEN-OXYGEN MIXED GAS PREPARATION DEVICE CAPABLE OF ADJUSTING HYDROGEN CONTENT AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/082362
Kind Code:
A1
Abstract:
A hydrogen-oxygen mixed gas preparation device capable of adjusting hydrogen content and a method therefor. The hydrogen-oxygen mixed gas preparation device comprises a shell for accommodating an oxygen production device, a hydrogen production device, a control module (14), and a power supply module (19), wherein the power supply module (19) is configured to supply power to each device; the oxygen production device is configured to separate oxygen from air and store the oxygen for later use; the hydrogen production device is configured to generate hydrogen or hydrogen-oxygen mixed gas for later use by means of a water electrolysis principle; the control module (14) is configured to control and adjust the flow of the oxygen, measure the concentration of the oxygen, and adjust the flow of the hydrogen-oxygen mixed gas and the hydrogen content to a preset range; and the oxygen generated by the oxygen production device and the hydrogen generated by the hydrogen production device or the hydrogen-oxygen mixed gas are or is converged to a gas outlet (17) of the hydrogen-oxygen mixed gas preparation device through a pipeline and then discharged after humidification or discharged directly. Further disclosed is a method for using the device. The advantages such as long service life, adjustable hydrogen content, adjustable flow of the hydrogen-oxygen mixed gas are achieved.
