Figure 1 is a schematic diagram of the proposed generator of hydrogen and oxygen.

The hydrogen and oxygen generator consists of a housing 1, with an even number of vertical cavities 2, separated by bulkheads 3. In each cavity, electrodes 4 with developed surfaces are connected to the power supply 5. In the upper part of each cavity there is a float 6, and a poppet valve 7, in the upper part of each cavity there is a cap 8, a gas dehumidifier 9, an outlet for hydrogen extraction tubes 10 and oxygen 11, which are connected to hydrogen receivers 12 and oxygen 13. The generator is equipped with a heat removal device 14, made in the form of a snake vetch, which passes through all of the housing, covering the electrodes with a developed surface. On the generator housing, pressure sensors 15, temperature 16 and level 17, a pump 18, an electrolyte drain tank 19 with a concentration sensor 20, a water tank 21 and an alkali tank 22, a control unit 23, a programming unit 24, a measurement unit 25, and electrically operated are installed valves 26 - on the alkali supply line, 27 - at the inlet of the pump 28 - at the entrance to the generator housing, 29 - at the input of the heat removal device into the generator body, 30 - at the entrance to the oxygen receiver, 31 - at the entrance to the hydrogen receiver, 32 - at the outlet of the generator housing, 33 - at the second inlet of the tank with electrolyte, 34 - at the first the inlet of the tank with electrolyte, 35 - at the outlet of the tank with electrolyte, 36 - at the outlet of the tank with water.

The hydrogen and oxygen generator operates as follows.

From the alkali tank 22, through the electrically operated valves 26 and 27, the alkali is supplied to the pump 18, from the outlet of which the alkali is fed through the 34 electrically controlled valve to the electrolyte drain tank, then from the water tank 21 through the electrically operated valves 36, 27 water is supplied to receiving pump 18, from the outlet of which, through an electrically controlled valve 34, water is supplied to the electrolyte drain tank 19, diluting the alkali to an alkali concentration of 25%, which is controlled by the concentration sensor 20 .. Then, the electrolyte from the electrolyte drain tank 19 enters through controlled valves 35 and 27 to receive a pump 18, from which electrolyte is supplied through an electrically controlled valve 28 to the generator body 1 to a level that is measured by a level sensor 17, at which the electrodes 4 are filled, or the floats 6 will not close the float valves 7. Next to the electrodes 4 supply DC electric voltage from the network 5. At the anode, under the influence of an electric current, oxygen will begin to be released, at the cathode - hydrogen. Gases emitted from the electrolyte will begin to accumulate in the upper parts of the cavities, the liquid level will drop and open the float valves, the gases will begin to flow through the dehumidifiers 9 into the caps 8, from where the gases are sent to the receivers 12 and 13 through separate gas exhaust pipes 10 and 11, and then through the electrically operated valves 30 and 31, to the consumer. The separation of gases in the generator is due to the fact that the electrodes 4 are separated by bulkheads 3 impervious from above and on the sides, but permeable from below, and also due to the fact that the electrodes are installed above the lower edges of the bulkheads, which eliminates the ingress of gases into neighboring compartments. Moreover, during the operation of the generator, water from the tank 21 is supplied through the electrically controlled valves 36 and 27 to the intake of the pump 18, from the output of which, through the electrically operated valve 29, water begins to circulate in the circuit of the heat removal device 14 to cool the cavities 2 of the generator. Further, when the generator is stopped, the water circulation in the heat removal device 14 is stopped, and the electrolyte is drained into the tank 19 through 32 and 33 electrically controlled valves. If necessary, you can add alkali from the tank 22 to maintain the required concentration of electrolyte. Next, the electrodes 4 are flushed; for this, water from the tank 19 is supplied through 36 and 27 electrically controlled valves to the intake of pump 18, from the outlet of which water starts to circulate through the electrically controlled valves 28 and 32 in the generator housing. If necessary, all operations are repeated sequentially. It should be noted that the pressure sensors 15, temperature 16 and level 17 are connected to the measuring unit 25, which, in turn, through the programming unit 24 is connected to the control unit 23, which interacts with all electrically controlled valves.

The proposed design of a hydrogen and oxygen generator allows to increase the cooling efficiency by 1.5-2 times, the speed of the control system by 2-3 times, reduce the electrolyte consumption by 15-20%, expand the range of stable operation of the generator for oxygen and hydrogen consumption by 1.5 -2 times.
