A known generator in a hydrogen-oxygen mixture containing a cylinder, a piston connected to the drive, and a cylinder head forming a closed cylinder volume, where an electrolyzer is installed, a nozzle with a cavitator for supplying an aqueous solution of an electrolyte to the electrolyzer, and a discharge valve with a nozzle for outputting the obtained gas mixture.

/ Patent of the Russian Federation, No. 2240381, С25В 1/04, November 20, 2004 / [1].

A disadvantage of the known generator is the design complexity and low productivity.

Closest to the proposed invention is a hydrogen-oxygen mixture generator, comprising a sealed housing, a compressor shaft connected to a drive, an electrolyzer, a system for feeding and spraying an aqueous electrolyte solution through a nozzle with a cavitator into the electrolyzer, and a nozzle with a cut-off for output gas mixture.

/ RF patent, No. 2280102, С25В 1/04, 07/20/2006, / [2].

The disadvantage of the closest analogue is the high energy consumption on the cell.

The technical problem solved by the invention is to increase the effective performance of the generator.

The problem is solved in that in a generator of a hydrogen-oxygen mixture containing a housing and a sealing entrance to the housing, a cover is placed in the housing on the bearings of the compressor shaft, for example axial, connected to the drive, for example with an electric motor, an injector with a cavitator, for example, in the form local narrowing of its channel, supply and atomization of an aqueous electrolyte solution, a pipe for removing the working fluid, an electrolyzer and a cutoff. The sealing cover in the housing cover is made with the possibility of adjustable, for example, blinds, air intake into the housing through the cavitator / for example, local narrowing of the channel through which air is taken /. Moreover, the nozzle with a cavitator is made with the possibility of feeding and spraying an aqueous solution of electrolyte into the flow of air taken into the housing. The pipe for outputting the working fluid is made with a cavitator, for example, also in the form of local narrowing of its channel and with the possibility of supplying the working fluid to the electrolyzer through this cavitator. Moreover, the electrolyzer is made in a separate sealed enclosure and with the possibility of feeding the hydrogen-oxygen mixture obtained in it through a cut-out, for example a water seal, to a consumer, for example, into the combustion chamber of a boiler plant. In this case, an adjustable air intake into the housing can be performed either through an annular channel with an annular cavitator, for example, in the form of an annular local narrowing of the annular channel, or through nozzles with cavitators, for example, a local narrowing of the channels of the nozzles.

The invention is schematically shown in the drawings, where: in Fig.1 - section of a generator; figure 2 is a view along arrow A in figure 1: figure 3 is a variant of air intake through nozzles with cavitators; figure 4 is a view along arrow B in figure 3.

An example of the implementation of the proposed solution.

The hydrogen-oxygen mixture generator comprises a housing 1 / Figs. 1-4/, a cover 2 that seals the entrance to the housing, configured for, for example, shutters 3 to draw air into the housing through either an annular channel 4 with an annular cavitator 5, for example, a local annular narrowing 6 channels, or through pipes 7 with cavitators 8, for example, local narrowing of 9 channels of pipes. A nozzle 10 with a cavitator, for example, local narrowing of its channel (not shown), supply and spraying of an aqueous electrolyte solution into a stream of air taken into the housing. The compressor shaft 11, for example, axial, connected to the drive 12, for example, an electric motor, located in the housing on the bearings. The outlet pipe 13 with a cavitator 14, for example, a local narrowing of the channel 15, made with the possibility of supplying the working fluid through this cavitator to the electrolytic cell 16, made in a sealed sealed housing 17 with the possibility of feeding the resulting hydrogen-oxygen mixture through the cut-off 18, for example, a gas seal, to the consumer 19 , for example, into the combustion chamber of a boiler plant. The generator also comprises a direct current source 20, for example an on-board battery, for supplying electrodes of the electrolyzer.

The generator of the hydrogen-oxygen mixture operates as follows.

To start the generator into operation, a direct electric current is supplied to the electrolyzer 16 / Fig. 1-4/ in a sealed separate housing 17 from a power source 20, for example an on-board battery, and a drive 12 is turned on, which rotates the shaft of the compressor 11, for example, axial. The operation of the compressor 11 at its inlet, sealed by the cover 2, creates a vacuum, due to which produce adjustable, for example, blinds 3, intake of atmospheric air into the housing 1 through made on the cover 2, for example, an annular channel 4 with an annular cavitator 5 or / or through nozzles 7 with cavitators 8. Into the flow of intake air through the nozzle 10 with a cavitator, for example, a local narrowing of the channel (not shown), an aqueous electrolyte solution, for example, an aqueous solution of caustic potassium, is fed and sprayed. In the cavitator of the nozzle 10, the supplied aqueous electrolyte solution due to cavitation partially dissociates, ionizes, its droplets are finest atomized and mixed with air. Then this air passes, for example, through the annular cavitator 5 with its local constriction 6 or / or passes through the cavitators 8 with local constriction 9. In the cavitator 5 or / or 8, again due to cavitation, a partial, not dangerous for the compressor operation 11 decomposition of water into hydrogen and oxygen, ionization and atomization of droplets. Further, due to the vacuum in the housing 1, the aqueous electrolyte solution turns into steam. Then it is compressed by the compressor 1 and under pressure behind the compressor through the outlet pipe 13 and through the cavitator 14 with local restriction 15 enters the electrolyzer 16. In the cavitator 14 of the pipe 13, again due to cavitation, partial dissociation, ionization and atomization of the droplets occurs, which then allows significantly save energy in the electrolytic cell 16. The aqueous solution of the electrolyte prepared in the described manner in the form of a working fluid, again under pressure, flows behind the compressor and passes through the electrolyzer 16 in a sealed Nominal housing 17 and due to the flow through it of a constant electric current from the source 20 finally dissociates into hydrogen and oxygen. Then, the resulting gas mixture through the cutter 18, for example, a water seal, enters the consumer 19, for example, in the combustion chamber of a boiler plant, where it is effectively burned, for example, in a mixture with some kind of fuel.

The proposed hydrogen-oxygen mixture generator in operation is highly productive and highly economical; it will find wide application for the development of environmentally friendly fuels, mainly for boiler plants for various purposes.
