Abstract

The invention relates to flame welding and cutting equipment, in particular to a water electrolysis hydrogen-oxygen flame welding and cutting machine. The machine is characterized in that: electrolytic cells are arranged in a U form; the electrolytic cells on the left and right two sides are symmetric; electrolyte in the electrolytic cells is continuous; the electrolytic cells on the two sides are connected with the anode and cathode of a direct current power supply respectively; the upper end parts of the electrolytic cells are provided with exhaust pipes which are connected with two flame arresters respectively; the flame arrester with a hydrogen outlet is provided with a pipe which is connected with both a pipe at the bottom of the flame arrester and a pipe leading to the middle lower part of a heat exchanger; a pipe arranged on an electrode copper tube connected with the cathode in the electrolytic cell is connected with the upper end of a radiation pipe of the heat exchanger, and the pipe arranged a copper tube connected with the anode is connected with the lower end of the radiation pipe of the heat exchanger; the pipe leading to the middle lower part of the heat exchanger is provided with a water pump which is communicated with the radiation pipe of the heat exchanger; the flame arrester with hydrogen outlet is provided with a pipe which is connected with a hydrogen connecting pipe on a welding and cutting head; and the flame arrester with an oxygen outlet is provided with a pipe which is connected with an oxygen connecting pipe on the welding and cutting head. The equipment is convenient, quick, environmentally-friendly and energy-saving.

Description

technical field [0001] The invention relates to flame welding and cutting equipment, in particular to an environment-friendly and energy-saving water electrolysis hydrogen and oxygen flame welding and cutting machine. Background technique [0002] Flame welding and cutting is a process in which combustible gas (acetylene, propane, etc.) and oxygen are combined to ignite to generate flames, heat steel for welding, heat the steel to a nearly molten state, and then release high-pressure oxygen to blow off the steel. In the past, the combination of bottled acetylene or propane and bottled oxygen was used to connect the welding torch for welding. This process produces carbon dioxide, which pollutes the environment and is inconvenient for transportation. Now some people are trying to use water electrolysis to produce hydrogen-oxygen mixture combined with bottled oxygen to replace the original welding and cutting method. But it is also necessary to have bottled oxygen, which is i...

Problems solved by technology

But there must also be bottled oxygen, which is inconvenient to transport

Moreover, because hydrogen, oxygen, and electrolyte are mixed together, there will often be tempering, shooting, and water spraying, which is not practical. This technology is still in the experimental stage.
