Electrolyzed Hydrogen Oxygen Mixing Device and Preparation Method

Abstract

The present invention provides an electrolytic hydrogen-oxygen combination device. Unique top slots are designed on the first slot and the second slot. The left and right sides are used to form gas passages to make the separation of hydrogen and oxygen more thorough. Bottom slots are provided at the bottom of the slots constituting the oxygen production reaction chamber and the hydrogen production reaction chamber, which are used to form liquid channels. For example, the bottom slots are opened on the right and left sides respectively, so that the oxygen-containing lye and the hydrogen-containing lye can circulate independently , the contact area between the electrode sheet and the electrolyte is increased, and the electrolysis is more efficient. The hydrogen production reaction chamber and the oxygen production reaction chamber are separated by a proton exchange membrane, which is conducive to the reduction of the electrode spacing, reduces the solution resistance, and lowers energy consumption. The high-efficiency and energy-saving electrolytic hydrogen-oxygen combination device is powered by DC power supply. Combining the above several measures, the electrolysis efficiency of the electrolysis device is greatly improved, and the disassembly is convenient, the preparation is simple, the application range is wider, and the use is more flexible.

Description

technical field [0001] The invention relates to the technical field of hydrogen and oxygen electrolysis, in particular to an electrolytic hydrogen and oxygen combination device and a preparation method thereof. Background technique [0002] With the decrease of fossil energy and the emergence of serious air pollution problems, clean energy is becoming the focus of attention, and hydrogen energy is undoubtedly the most ideal choice. The previous electrolytic hydrogen-oxygen electrolyzer has the problems of large volume, high energy consumption (5kWh / Nm3 H2), and low efficiency (50%-70%). The existing electrolysis device has low efficiency due to the large distance between the two electrodes (8mm), and some electrolysis devices have complex structures and are difficult to assemble and disassemble, resulting in limited application range. Moreover, the use of asbestos paper as a diaphragm in some electrolysis device structures will reduce the purity of hydrogen and oxygen. Ther...

Problems solved by technology

The previous electrolytic hydrogen-oxygen electrolyzer has the problems of large volume, high energy consumption (5kWh / Nm3 H2), and low efficiency (50% to 70%)

The existing electrolysis device has low efficiency due to the large distance between the two electrodes (8mm), and some electrolysis devices have complex structures and are difficult to assemble and disassemble, resulting in limited application range

Moreover, the use of asbestos paper as a diaphragm in some electrolysis device structures will reduce the purity of hydrogen and oxygen. There is also an electrolysis device (Chinese patent application number 201610439066.X) with a low degree of separation and integration between the gas circuit and the electrolytic cell, and there is no electrolyte circulation system
