Description

  The present invention relates to an underwater temperature raising apparatus using arc heating, and more particularly to an underwater temperature raising apparatus using a high temperature arc as a heat source.

  Conventionally, as a means for raising the temperature of the water, a kettle, a boiler, a sheathed heater or the like is used, and the temperature is raised by indirectly warming the water in the interior with a heat source located outside the container.

  Moreover, wood, gas, kerosene, and heavy oil are used as the heat source, and carbon dioxide is generated by burning wood, fossil fuel, etc., which causes global warming. There was also a problem of becoming exhausted.

  Therefore, the inventor of the present invention has invented the temperature rise of water using the heat of arc discharge.

  This technology that uses the heat of arc discharge is used in arc heating wind tunnels that conduct research and development of thermal protection materials for space shuttles and tests that simulate the reentry of the atmosphere.

  There is also an arc-type ladle heating device. That is, the ladle was used in a casting factory where a molten metal is transported using a refractory container and a product is taken out through a pouring process in which the molten metal is poured into a mold.

  However, there is no method and apparatus for raising the temperature of water by arcing in water and generating heat by causing water molecules to collide with each other, that is, there is no method and apparatus for raising the temperature by arc heating in water. It was.

  Therefore, the present invention develops and provides an underwater temperature raising apparatus using arc heating that is inexpensive and friendly to the earth by using the heat of arc discharge as a heat source for raising the temperature of water and directly heating the water.

  And this invention puts water in an arc generation tank, electrically heats using arc discharge by an arc generator provided in the water, and generates a heat source directly in the water. An arc generator composed of a plurality of carbon rods is provided by using a three-phase AC power source provided in an electric heater that uses the heat of arc discharge of the apparatus to generate a heat source directly in water. Heating is performed by bringing the ends of two carbon rods into contact with each other while passing a strong current, and the anode is heated to about 3500 ° C and the cathode is heated to 2800 ° C. We are going to develop and provide an underwater temperature raising device.

  According to the present invention, an extremely beneficial effect can be obtained by directly heating the water temperature by arc heating with an arc generator provided in water in the arc generation tank.

  Further, the inflow port provided near the bottom of the arc generating tank is formed at an angle deviating from the axis toward the central axis of the tank, so that water flows in along the inner periphery of the cylindrical tank, Moreover, since it turns and raises toward the outflow port (3) near the upper part of this tank, there exists an effect that temperature rising is attained evenly.

  Furthermore, by making the container main body into a pressurizing structure, there is an effect that the temperature raising time can be shortened.
