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 cavitators, for example, local channel narrowing, supply and spraying an aqueous solution of an electrolyte, a nozzle for discharging a gas mixture, an electrolyzer and a cut-off, a sealing cap for entering the housing; the cover is configured to, for example, shutters, draw air into the air yc cavitator through such a local constriction 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 in this case is made in the form of a cavitator with a central body, for example, a local narrowing of the channel with the central body by supplying power from a constant current source, for example, from the battery, to the cavitator elements, for example, to the local narrowing of the channel and the central body, and is installed in the nozzle for the output of the gas mixture with the possibility of supplying the gas mixture through the electrolyzer with the Central body and through a shut-off device, such as a check valve, to the consumer, for example into the combustion chamber of the 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 channel, or in the form of a nozzle with cavitators, for example, local narrowing of the channels of the nozzles.

The invention is schematically shown in the drawing, where:

figure 1 - section of the generator; figure 2 is a view along arrow A in figure 1; figure 3 - version of the 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 hydrogen-oxygen mixture generator comprises a housing 1 (Figs. 1-4), a cover 2 sealing the entrance to the housing, configured to, for example, shutters 3, take air into the housing, through either an annular channel 4 with an annular cavitator 5, for example local ring narrowing of the 6th channel, or through nozzles 7 with cavitators 8, for example local narrowing of the 9th channel of the nozzles. A nozzle 10 with a cavitator, for example, local narrowing of its channel (not shown), supplying and spraying electrolyte into a stream of air drawn into the housing located in the housing on the bearing bearings of the compressor shaft 11, for example, an axial shaft connected to the drive 12, for example an electric motor. The electrolyzer, made in the form of a cavitator 13, for example, a local narrowing of the channel 14 with the central body 15, by supplying a direct electric current, for example, from the battery 16 to the elements of the cavitator, for example, to its local narrowing and to the central body, is installed in the pipe 17 for outputting gas mixtures with the possibility of supplying a gas mixture through an electrolyzer with a central body and through a cut-off 18, for example a check valve, to a consumer 19, for example, into a boiler furnace.

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, and a constant electric current is supplied from the power source 16 to the electrodes 14 and 15 of the electrolytic cell 16. The compressor 11 creates a vacuum at its sealed inlet cover 2, due to which an adjustable shutter 3 atmospheric air intake into the housing 1 through a cover 2 made on the cover, for example, an annular channel 4 with an annular cavitator 5, for example, a local annular restriction 6. Into the flow of air taken in by a nozzle 10 with a cavitator (not shown) under electrolyte, for example, an aqueous solution of potassium hydroxide, cools and is sprayed. Due to cavitation in the cavitator of the nozzle 10, the electrolyte partially dissociates, ionizes, its droplets are finest atomized and mixed with air. Then this mixture passes through the annular cavitator 5 and, again, due to cavitation, the decomposition of water, its ionization and atomization of droplets are further to the limit that is not hazardous for the compressor 11. Further, due to the vacuum in the housing 1, the electrolyte is converted into steam. Then this mixture is compressed by compressor 11 and fed into the nozzle 17 for withdrawing the gas mixture and driven through the local ring narrowing 14 formed by the central body 15 of the electrolyzer 13, where due to cavitation and due to the flow of direct current through the electrolyte, the nozzle 10 is already partially dissociated in the cavitator and in cavitator 5, water vapor is completely decomposed into hydrogen and oxygen, thereby achieving high efficiency and productivity of the device. Then the gas mixture through the cut-off 18, for example a check valve, is supplied to the consumer 19, for example, in the combustion chamber of the boiler plant. And is burned.

The proposed generator of the hydrogen-oxygen mixture in operation is highly efficient and highly economical. It will be widely used to produce environmentally friendly fuel for boiler plants for various purposes.
