Description

technical field [0001] The invention belongs to the field of hydrogen and oxygen generation in water electrolysis, and in particular relates to an independent electric-level mutual coupling type water electrolysis hydrogen and oxygen generator. Background technique [0002] Water is the most abundant substance on the earth. Humans have long discovered that water is composed of hydrogen and oxygen, and discovered the phenomenon that water can be electrolyzed to produce hydrogen and oxygen before the 19th century. Water electrolysis of hydrogen and oxygen has been included in classic physics courses . After water is decomposed into hydrogen and oxygen, it can burn at a certain temperature, release heat, and then synthesize water. When water is ionized to produce hydrogen and oxygen, it can obtain fuel and combustion aid, and complete the material conditions for combustion. It’s just that due to human technical limitations, the cost of ionizing water into hydrogen and oxygen i...

Problems solved by technology

Connect positive and negative electricity to each pair of electrodes respectively, the water in the electrolyte solution between each pair of electrodes is electrolyzed, and hydrogen and oxygen are produced on the surface of the two electrodes, because the hydrogen and oxygen produced in the same liquid are In a chamber, it is difficult to separate when they are mixed together. For example, a diaphragm is added to each pair of electrodes to separate hydrogen and oxygen. Since the electrolyte is shared, the volume of gas produced by the positive and negative electrodes is different, and the water consumption is different. The pressure in the cavity is also different, and the equipment will be extremely complicated; the gas separation of the generated mixed gas is not only complicated in equipment, but also difficult to separate thoroughly. Therefore, the separation of hydrogen and oxygen is a difficult problem to solve; hydrogen and oxygen At the same time, once the gas encounters an open flame, it will burn immediately, and it is easy to backfire in the pipeline, and the gas safety is poor; both electrodes are immersed in the electrolyte, and the hydrogen and oxygen gas generated will escape from the liquid, and the water will not The gas forms resistance, and the gas produced at the same time blocks the contact between the electrode and the liquid, hindering the further reaction of the electrode; the electrolyte near the electrode is partially reacted, the concentration decreases, and the ability to exchange electrons decreases. It is very dense, and the stirring of the liquid is not easy to achieve, etc., all of which affect the generation of hydrogen and oxygen. Therefore, the existing hydrogen and oxygen generators have low efficiency, mixed hydrogen and oxygen, poor safety, large equipment volume, and large capacity. The equipment is not easy to manufacture, and the equipment cost is high.
