A hydrogen-oxygen generator (also known as a Brownian gas generator, water welding machine, etc.) is a device based on the principle of water electrolysis (electrochemistry) that decomposes water into hydrogen and oxygen, using the mixture as fuel.
Its core chemical reaction is the overall reaction of water electrolysis: 2H₂O → 2H₂↑ + O₂↑. Hydrogen is used as fuel, oxygen assists combustion, and the combustion product is water, resulting in no pollution.
A hydrogen-oxygen generator generally consists of a power module, an electrolytic cell, an electrolyte, a gas-liquid separation system, a gas scrubbing/purification system, a circulating cooling system, safety devices, and an intelligent control system. The power module converts AC power to DC power to supply the electrolytic cell. The electrolytic cell is the core device for water decomposition and consists of multiple electrolytic plates. The electrolyte is commonly an aqueous solution of sodium hydroxide (NaOH) or potassium hydroxide (KOH). The gas-liquid separation system separates the generated gas from the electrolyte. The gas scrubbing/purification system removes trace amounts of moisture and electrolyte from the gas. The circulating cooling system maintains the equipment temperature. Safety devices include multi-stage backfire prevention systems and pressure relief devices. The intelligent control system automatically monitors parameters such as pressure, liquid level, and temperature.
The workflow is as follows: After external power is input, it is rectified/inverted by the power module to become DC power suitable for electrolysis and applied to the electrodes of the electrolytic cell. Water molecules electrolyze under the influence of the electric field, producing hydrogen at the cathode and oxygen at the anode. The resulting mixed gas, along with the electrolyte, enters a gas-liquid separator for separation. The gas then undergoes a washing/purification system to remove trace amounts of moisture and electrolyte. The purified gas is then output to the gas-using equipment after passing through safety devices (such as a water seal tank and a flame arrester). The entire process is monitored by the intelligent control system to ensure safe operation.
