Description

The invention relates to technology for electrochemical production, in particular to devices for electrolysis of water, and can be used to produce environmentally friendly fuel mainly for boiler plants.

A known generator of a hydrogen-oxygen mixture containing a cylinder, a piston associated with 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 and a discharge valve for discharging the gas mixture. (RF patent No. 2240381, С25В 1/04, November 20, 2004) [1].

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

Closest to the proposed invention is a generator of a hydrogen-oxygen mixture, comprising a housing and a sealing entrance to the housing, a cover, a compressor shaft connected to the drive, a nozzle with a cavitator for feeding and spraying an aqueous solution of an electrolyte, a nozzle for discharging a gas mixture, an electrolyzer and a cutter . (RF patent №2280102, С25В 1/04, 07/20/2006) [2].

The disadvantage of the closest analogue is the high energy consumption on the cell and its low efficiency.

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, a compressor shaft, for example an axial shaft, connected to the drive, for example with an electric motor, a nozzle with a cavitator, for example, local channel narrowing, supply and spraying an aqueous electrolyte solution, a nozzle for discharging a gas mixture, an electrolyzer and a cut-off. The cover sealing the entrance to the housing is made with the possibility of, for example, adjustable air intake blinds into the housing through the cavitator, for example, local narrowing of the channel. Moreover, the nozzle with a cavitator is made with the possibility of feeding and atomizing the electrolyte into the flow of air taken into the housing. The electrolyzer is equipped with electrodes made in the form of cavitators, for example, local narrowing of the channel, with direct current supply from the power source, sequentially installed in the pipe for outputting the gas mixture with the possibility of supplying the gas mixture through these electrodes and through a shut-off device, for example a non-return valve, to the consumer, for example, in the combustion chamber of a boiler plant. In this case, the cavitator for adjustable air intake into the housing can be made either in the form of an annular channel with an annular cavitator, for example, an annular local narrowing of the annular channel, or in the form of a nozzle with cavitators, for example, local narrowing of the ducts of the nozzles.

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

An example of the implementation of the proposed solution.

The generator of the hydrogen-oxygen mixture comprises a housing 1 (Figs. 1-4), a cover 2 that seals the entrance to the housing, configured to, for example, be adjusted by the air intake shutters 3 to the housing through either an annular channel 4 with an annular cavitator 5, for example, a local annular narrowing of channel 6, or through nozzles 7 with cavitators 8, for example, local narrowing of 9 channels of nozzles, nozzle 10 with cavitator, for example, local narrowing of its channel (not shown), supply and atomization of electrolyte into the flow of air taken into the housing. In the housing on the bearings, a compressor shaft 11, for example, an axial shaft, connected to the drive 12, for example an electric motor, is placed. The cell 13 is equipped with electrodes made in the form of cavitators 14 and 15, for example, local narrowing of the channel 16, with power supply from a direct current source 17, sequentially installed in the pipe 18 for outputting the gas mixture with the possibility of supplying the gas mixture through these electrodes and through the cutoff 19. for example a check valve, to the consumer, for example, into the combustion chamber of a boiler plant 20.

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

To start the generator, a drive 12 is turned on, which rotates the shaft of the compressor 11, for example, axial, and a constant electric current is supplied from the power source 17 to the electrodes 14 and 15 with a local narrowing of the channel 16 of the electrolyzer 13. The operation of the compressor 11 creates an input on its sealed cover 2 underpressure. Due to this, atmospheric air is regulated, for example, by shutters 3, into the housing 1 through either an annular channel 4 with annular cavitator 5 made on the lid 2, for example, local restriction 6, or through nozzles 7 with cavitators 8, for example, local restrictions of 9 channels. An air nozzle 10 with a cavitator, for example a local narrowing of the channel (not shown), is fed and sprayed with an electrolyte, for example, an aqueous solution of potassium hydroxide. Due to cavitation in the cavitator of the nozzle 10, the supplied electrolyte partially dissociates, ionizes, its droplets are finely atomized and mixed with air. Then this mixture passes through cavitators of either 5 or 8 and, again, due to cavitation, a further decomposition of the water to hydrogen and oxygen, ionization and atomization of droplets, to the limit that is not dangerous for compressor 11, occurs. Further, due to the vacuum in the housing 1, the electrolyte is converted into steam. Then this mixture is compressed by the compressor 11 and under pressure behind the compressor it is supplied to the pipe 18 for withdrawing the gas mixture and sequentially passes through the cavitators 14 and 15 of the electrolyzer 13, for example, the local narrowing of the channel 16 of the pipe, where due to cavitation and due to the flow of direct current through the electrolyte partially the nozzle 10 already dissociated in the cavitator and in the cavitator, for example 5, water vapor is completely decomposed into hydrogen and oxygen, thereby significantly reducing the waste of electricity on the electrolyzer and achieving high economic spine and device performance. Then the gas mixture through the cut-off 19, for example a check valve, enters the consumer, for example in the combustion chamber of the boiler unit 20, and is burned.

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