More specifically, the present invention relates to an electrolysis device for efficiently separating and collecting hydrogen and oxygen generated during electrolysis of water and a combustion device using the same.

The electrolysis of water is usually done by adding a positive electrode to one side of the electrolytic cell and a negative electrode to the other side, and adding a electrolyte such as sulfuric acid, sodium hydroxide or potassium hydroxide to the water and passing a direct current in the state filled with electrolyte to improve conductivity. Electrolysis is performed, and hydrogen generated from the cathode rod and oxygen generated from the anode rod are usually discharged in a mixed gas state to be used as an energy source of various combustion apparatuses including a torch and the like.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a schematic representation of the electrolysis device 100 of the present invention.

First, the electrolytic cell 101 is provided with a switching switch 102 capable of alternately adjusting the cathode / anode to alternately change the negative electrode and the positive electrode at regular intervals to periodically remove the reducing material generated from the negative electrode. In addition, the pump 104 is connected to the electrolytic cell 101 to circulate the electrolyte, and prevent damage to the pump 104 due to foreign matter (or precipitates precipitated by the electrochemical reaction of ions dissolved in water). To this end, a pre-filter 105 constructed by a heat fusion method is installed at the inlet end of the pump. The electrolyte passing through the pump passes through a radiator 106 with a cooling fan (not shown), and the temperature of the electrolyte is automatically or manually adjusted in an appropriate range (typically 40 -60 ° C) by the radiator.

Oxygen and hydrogen separated and discharged by the electrolyzer pass through separate feed tanks 107a and 107b, respectively. The water supply tanks 107a and 107b have a structure having a plurality of holes in order to increase the bubble effect of the gas, thereby increasing the bubbling effect and removing most of the electrolyte solution.

Hydrogen and oxygen gas from which the electrolyte is removed passes through the primary separators 108a and 108b and the secondary separators 109a and 109b, where most of the moisture is removed, and the removed water is again supplied to the water supply tank 107a. 107b), purely purified hydrogen and oxygen gas are stored in a hydrogen reservoir and an oxygen reservoir, respectively. If necessary, hydrogen and oxygen can be used as direct energy sources. When using hydrogen and / or oxygen stored in the reservoir as an energy source, or when using hydrogen and oxygen as an energy source directly, they may be discharged at a constant pressure by passing them through the equalization regulator 110 to increase energy efficiency. .

On the other hand, the forced water pumps 111a and 111b are installed between the electrolyzer 101 and the water supply tanks 107a and 107b to maintain a constant level of the electrolyte solution to induce smooth electrolysis.

The electrolysis device of the present invention can further increase energy conversion efficiency by suppressing overvoltage by quickly removing bubbles formed on the electrode surface by additionally installing a vibrator (not shown) at the lower end of the electrolytic cell 101. If necessary, the water level regulator may be installed between the forced water pumps 111a and 111b and the electrolyzer 101 to automatically adjust the water level within an appropriate range.

2 shows a schematic diagram of an electrolytic cell 200 in which electrolysis of water occurs. In the electrolyzer 200, a cathode 201, a plurality of metal plates 202a, 202b, 202c (hereinafter referred to as '202') and an anode 203 are disposed, and these are separators 204a, 204b, 204c, 204d, and below, respectively. Separated from each other by "204". Insulating rings 205a, 205b, 205c, and 205d are attached to the cathode 201, the metal plate 202, the anode 203, and the separator 204, and the cathode 201, the metal plate 202, the anode 203, The separation membrane 204 and the insulating rings 205a, 205b, 205c, and 205d are respectively sealed by sealing (not shown). The separator 204 having the insulating ring 205d prevents hydrogen and oxygen from mixing with each other due to the electrolysis of water. The cathode 201, the metal plate 202, the anode 203, and the separator 204 have lower ends of the electrolyte outlets 206, which are connected to each other through an electrolyte transfer tube (not shown) to move the electrolyte. The cathode 201, the metal plate 202, the anode 203, and the separator 204 have upper ends of the hydrogen outlet 207 and the oxygen outlet 208, which are coated with an insulating material. It is connected by the not shown) and the oxygen discharge pipe (not shown). In the hydrogen discharge pipe that provides the discharge passage of hydrogen gas generated in the negative electrode 201 or the negative portion of the metal plate 202, hydrogen discharge grooves (not shown) exist only in the negative electrode gas layer, so that hydrogen generated by electrolysis is oxygenated. Oxygen discharge pipe (not shown) provides a discharge passage of oxygen gas generated at the anode, and the oxygen discharge groove (not shown) exists only in the anode gas layer, so that oxygen generated by electrolysis can be separated from hydrogen. It is configured to move separately. Therefore, hydrogen and oxygen separated from each other by the separator 204 can move through the hydrogen discharge tube and the oxygen discharge tube without being mixed with each other.

3 illustrates a method of coupling between the insulating ring 205d and the separator 204. The insulating ring 205d is formed of an insulating material. A hydrogen discharge port 207 and an oxygen discharge port 208 are formed at an upper end of the insulating ring 205d, and an electrolyte discharge port 206 is formed at the lower end of the insulating ring 205d. Is formed. The insulating ring 205d and the separator 204 are coupled to each other through the inner diameter 209 of the insulating ring and the respective outlets.

3 illustrates the coupling between the insulating ring and the separator, but the coupling between the insulating ring and the metal plate and the insulating ring and the electrode plate is achieved in the same manner as in FIG. 3.

4 is a principle in which water is electrolyzed by the metal plates 202a, 202b, and 202c disposed between the cathode 201 and the anode 203 to generate a large amount of hydrogen and oxygen, and the generated hydrogen and oxygen are separated. It is shown. When current flows through the electrode, the electrons of the metal plate move toward the anode, and the electron density is different from each other on the surface of the metal. Therefore, the positive electrode (+) and the negative electrode (−) are induced to cross each other in the metal plate. Eventually, a plurality of cathode and anode powers are simultaneously generated, so that electrolysis of water is simultaneously generated in an electrolytic cell in which a plurality of cathodes and anodes are formed, and a large amount of hydrogen and oxygen are simultaneously generated. Can be obtained in large quantities. These are separated from each other by the separation membranes 204a, 204b, 204c, and 204d so that oxygen and hydrogen can be separated from each other and moved.
