Description
Technical Field
The present invention relates to a steam generator, and more particularly, to a continuous supply of fluid to a space between an inner electrode and an outer electrode. And a device for generating steam by repeating the processes of electrolysis of fluid, generation and recombination of gas and ions. The fluid moving direction of electrolysis is from the lower part to the upper part straight line movement, because of the fluid moving heating fluid of single channel mode, the structure of the electrolysis device is simple, the vibration and noise produced by fluid pulsation are prevented, the supplied fluid can produce a large amount of steam, and the effectiveness of the electrolysis mode is utilized to quickly produce steam.
Background
In general, fluid heating methods include an electric boiler, an electrode boiler, a hot water generating device, and a vortex heating device.
The electric boiler is a mode of heating fluid by electricity, a heating body is arranged in a hot water tank, and a power supply is applied to the heating body, so that the fluid is heated by heat generated by a resistor.
Unlike an electric boiler, an electrode boiler does not use a heating body, and vibration current is applied to an electrode, so that current for ion movement is a mode for heating fluid.
The hot water generating device has a multi-grooved disc or cylinder. The rotation of the disk or cylinder causes cavitation and cavitation produces heat.
Vortex heating devices are ways to force a fluid to generate a vortex, which generates heat.
The electrode boiler requires a high operating current due to ionic conduction of the fluid itself and limited current heating, and the electrolysis process easily corrodes the electrode surface, so that the heat generation efficiency is not high.
In order to generate kinetic energy corresponding to the amount of heat generated, the hot water generating device and the vortex heating device require relatively large power devices, so that the device is high in manufacturing cost and high in vibration noise.
In order to solve the above problems and disadvantages, a heat generating device using electrolysis heat is invented.
FIG. 1 shows a prior art electrolytic hot water heating apparatus.
The electrolytic heating device comprises;
water tank (10): stored to supply heated fluid
Internal electrode (11): spherical shape arranged in the inner space of the water tank (10)
External electrode (12): spherical shape, which surrounds the outside of the inner electrode (11) while keeping a certain distance from the inner electrode (11)
The surface of the outer electrode has a plurality of perforations (13), and water inside the water tank (10) flows into a space between the outer surface of the inner electrode (11) and the inner surface of the outer electrode (12) through the perforations (13).
If power is applied to the internal electrode (11) and the external electrode (12), the electrolysis of water occurs in the space between the internal electrode (11) and the external electrode (12), and the gas and ion generation and recombination process is repeated to generate heat.
In an electrolysis-type heating device, it is required that the internal electrode (11) and the external electrode (12) are kept at a constant interval for easy electrolysis.
Since the internal electrode (11) and the external electrode (12) are spherical, the conventional electrolytic device is not easy to manufacture, and the precision of the interval between the electrodes is difficult to maintain. The fluid is supplied through the perforation (13) of the outer electrode, and the heated fluid moves along the sphere curve between the inner electrode (11) and the outer electrode (12), so that the fluid circulation is unfavorable, and therefore, the water in the water tank needs a relatively long time and a large amount of electric power to be heated to a certain temperature, and the problem of great heat loss is caused.
