The utility model is characterized in that electrolysis part passes through an electrolytic tank which has a structure welded by steel pipes, and the inner wall has a plastic spraying layer; the pressure regulating part adopts an oxyhydrogen pressure tank, and a regulating valve for controlling temperature and pressure is arranged on the oxyhydrogen pressure tank; the flame stabilizing part adopts a flame stabilizing agent tank.
Description
The utility model relates to a kind of gas welding, the used equipment of gas cutting, especially a kind of gas welding without acetylene cylinder, gas cutting equipment.
In the past, aspect gas welding, gas cutting, that generally adopts has acetylene--gas welding method and liquefied petroleum gas-scarfing oxygen method.Acetylene-oxygen method major defect is that the technological process of production is long, owing to from mining-transportation-sintering-acetylene gas reaction-storage-transportation-user, so its equipment investment is bigger, and environmental pollution is arranged.Concerning the user, purchase acetylene, the oxygen market price is higher, freight is also high.Liquefied petroleum gas-scarfing oxygen method major defect is flame temperature low (is lower than acetylene-oxygen flame 800 ℃), and oxygen consumption is more.
The purpose of this utility model is: be energy-conservation, reduction usage charges and pollution-free, propose a kind of welding and cutting device of Hydrolyze method.
The hydrolysis welding-cutting machine comprises that electrolysis, steam circulation, aqueous vapor are separated, parts such as pressure is regulated, steady flame.In order to improve the pressure of water electrolytic gas, adopt electrolytic cell 2, for high pressure resistant, electrolytic cell adopts the steel pipe Welding Structure, for solving corrosion-resistant and Insulation Problems, inwall adopts plastic spraying layer 23, have in the electrolytic cell between the multipole 22, multipole of the netted or sheet of some chemical deposits and separate with plastics spacer 26, solved corrosion-resistant and reduction overpotential problem, and saved caloric value when power consumption has reduced electrolysis again, netted multipole is under pole plate diameter same case, and electrode surface area strengthens and improved electrolytic efficiency.Pressure is regulated and is adopted hydrogen-oxygen pressurized tank 4, and temperature control valve (TCV) 8 and pressure-regulating valve 9 are arranged on the pressurized tank, and steady flame adopts the steady flame agent jar 5 of band sprayer 10.
Accompanying drawing 1 is the each several part schematic diagram of hydrolysis welding-cutting machine, and 1 is water pot among the figure, the 2nd, and electrolytic cell, the 3rd, radiator, the 4th, hydrogen-oxygen pressurized tank, the 5th, steady flame agent jar, the 6th, rectifier, the 7th, automatic control unit, the 8th, temperature control valve (TCV), the 9th, pressure-regulating valve, the 10th, sprayer, the 11st, filter, the 12nd, water circulating pump, the 13rd, moisture trap, the 14th, pressure regulator, the 15th, pressure switch, the 16th, high pressure gauge, the 17th, low-pressure meter, the 18th, check valve, 19, the 20th, flash-back arrestor, the 21st, anode, the 22nd, multipole, the 23rd, plastic spraying layer, the 24th, pot shell, the 25th, negative electrode, the 26th, spacer, the 27th, mandrel.
Accompanying drawing 2 is cutaway views of electrolytic cell, and 21 is anodes among the figure, the 22nd, and multipole, the 23rd, plastic spraying layer, the 24th, pot shell, the 25th, negative electrode, the 26th, spacer, the 27th, mandrel.
The utility model is realized like this: the electrolysis of water, be distilled water or boiling water to be added 20% NaOH or potassium hydroxide form electrolyte and be used in the water pot 1, through filter 11, water circulating pump 12, water is imported electrolytic cell 2, and the direct current that produces by controlled rectifier 6 splits water into hydrogen H
2With oxygen O
2Send gas-vapor mix back to water pot with the certain flow rate pressure through plate fin type radiator 3, gas-vapor mix utilizes " dividing plate " effect to carry out the carbonated drink separation first time at water pot end socket place, after steam-water separator 13 carries out the carbonated drink separation second time, then the hydrogen and oxygen mixture of " drying " is sent into hydrogen-oxygen pressurized tank 4.Be to adapt to the requirement of gas welding and gas cutting technology, fuel gas hydrogen should use low pressure (0.005～0.1Mpa), and gas welding or the requirement of gas cutting different-thickness steel plate, oxygen usefulness elevated pressures (0.3～0.8Mpa).Therefore this machine is provided with large-scale hydrogen-oxygen gas tank, (0.3～0.8Mpa) utilizes the different principle of hydrogen-oxygen proportion, during operation the Hydrogen Vapor Pressure control valve 9 on jar 4 tops is reduced to 0.005～0.1Mpa of technological requirement according to the operating pressure of the thickness adjustable pressure relay 15 of steel plate.Because hydrogen or hydrogen and oxygen mixture are a kind of detonation gas, in combustion process, may produce detonation, make combustion instability, through test of many times, we add the atomizing gaseous mixture that micro ethanol or gasoline add ethanol in hydrogen, and effect is very good, therefore, add steady flame agent jar 5 in the welding-cutting machine system, steady flame agent jar 5 is provided with atomizing atomizer 10, makes steady flame dosage adjustable.In order to guarantee handling safety, this machine has also been taked explosion precaution: the temperature of (1) control oxyhydrogen, the control temperature from 0 ℃～100 ℃ adjustable, water electrolytic gas is controlled at 50 ℃～80 ℃ for well, above design temperature, robot control system(RCS) promptly stops electrolysis; (2) control water electrolytic gas pressure, controlled pressure is adjustable, surpasses setting pressure, and robot control system(RCS) stops electrolysis, when pressure decline electrolysis recovers; (3) dry annealing device, at hydrogen and oxygen outlet dry annealing device 19 and temper device 20 are set all, as produce tempering, pressure increases suddenly, on hydrogen-oxygen pressurized tank 4 and steady flame agent jar 5, all be provided with the compression-type rupture disk, do not have fragment during this type rupture disk explosion, can be after the explosion with hydrogen-oxygen pressurized tank 4 and 5 pressure releases of steady flame agent jar, for preventing tempering influence jar 4, be provided with check valve 18 at the hydrogen mouth again.
The utility model and prior art ratio have the following advantages: the investment that the energy is nontoxic, tasteless, pollution-free, usage charges are low, convenient transportation, saving are built acetylene, oxygen installation, and save coal, electric equal energy source.
