Description

Boiler heat exchanger using plasma {High temperature plasma boiler}

The present invention relates to a boiler heat exchanger using a plasma, and to a boiler heat exchanger using a plasma that can be applied to a heater such as a boiler by using a high temperature plasma induced by radio waves.

In general, a plasma is defined as a gas mixture in an ionized state. When enough heat is applied to the gas, a large number of electrons are released from the confinement of the nucleus due to collisions between atoms, which is called a fourth state of matter. Unlike hot gases, which consist only of electrically neutral atoms, plasma has a mixture of oppositely charged particles, the electrons and the nucleus. Therefore, the electric field is generated by the charge separation between the ions and the electrons, but the neutral and locally, the current and the magnetic field are generated by the flow of the charge.

Normally, plasma is formed by using an inert gas such as argon, and once generated argon ions receive sufficient energy from the outside to continue the ionization process and keep the plasma stable. At this time, the temperature reaches several thousand degrees.

At present, most Korean boilers are supplied with both heating and hot water supply, and heat exchangers such as boilers can use hot water generated by burning appropriate fuels (heating kerosene, gas, electricity) for heating purposes. have. In other words, the boiler is a device for generating steam or hot water by the flame combustion gas and other high-temperature gas, the hot water generated at this time to perform a heating and hot water function to create a convenient and warm heating environment.

The general flow of the boiler operation is to supply the fresh air as the blower operates, to discharge the residual gas in the firebox and the communication, the high voltage generated in the transformer sparks at the electrode poles in the firebox to form the initial embers, The pump is operated and supplied to the firebox at a pressure suitable for combustion. Along with the initial flame formation, the flame detector senses that the combustion continues and the secondary governor is opened to normal combustion.

The boiler is to maintain the temperature of a constant space at a comfortable haptic temperature by using the heat generated by the combustion as described above, for this purpose it is artificially adjusted to the temperature and humidity. Therefore, in order to control the temperature artificially, it can be divided into a heat generating device that generates heat, transporting the generated heat to a necessary place, and consuming the heat. In addition, the hot water reaching the set temperature from the boiler is supplied to the distributor through the heating outlet pipe and the heating supply pipe, where each pipe is supplied to the place where the heating is required.

Conventional boilers operated by such a configuration have to use consumable fuels that have unstable elements such as fire or explosion, such as oil or gas, and thus it is difficult to promote the safety of the user. It is difficult to obtain due to the exhaustion of gas, and there is a problem that an environmental problem occurs due to incomplete combustion.

In addition, since a separate ignition device is required to burn the fuel as described above, there are various problems such as a large volume, an increase in component costs, and an inability to expect an excellent heating effect compared to the investment cost.

The present invention has been made in consideration of the above problems, and its object is to apply a high heat of plasma to the heat exchanger, thereby enabling continuous heat exchange without filling of fuel, thereby reducing the economic burden, fuel such as oil or gas It is to provide a boiler heat exchanger using plasma that can be used semi-permanently by preventing accidents caused by fire and preventing human injury, preventing resource depletion and environmental pollution, such as oil or gas.

According to the present invention, a filling port for introducing gas is formed at one end, and a discharge port for discharging air is formed at the other end, and a plasma generating container filled with gas therein is connected to and installed at an outlet side of the plasma generating container. A vacuum pump, an induction coil installed outside the plasma generating vessel, an impedance matching unit installed in connection with the induction coil, a radio wave generator connected to the impedance matching unit and generating a radio wave, and A heating pipe installed through the plasma generating vessel wound with an induction coil, a circulation pump connected to the heating pipe and connected to the connection pipe, and the connection pipe is connected to one side, and water for circulation of the heating pipe is stored and supplied therein. Including a storage tank to which the pipe and the discharge pipe are connected / installed, respectively, It is to provide a boiler heat exchanger using a plasma for raising the temperature of the water in the heating pipe conveyed by the circulation pump by the plasma.

The plasma generating container 130 is composed of a quartz tube, the induction coil 140 is wound on the outside a number of times, the inert gas or water such as argon, helium, neon, krypton, xenon, nitrogen, oxygen, etc. It is charged below 200 Torr. At this time, the induction coil is formed of a copper tube, the pressure of the gas filled in the plasma generating vessel 130 is preferably 0.1 ~ 10 Torr.

In addition, the inlet 131 and the outlet 132 for inflow and outflow of gas are formed at both ends of the plasma generation vessel 130, respectively, the inlet 131 and the outlet 132, the inflow of gas And opening and closing switch 133 is provided to facilitate the discharge, respectively.

In addition, a vacuum pump 150 is connected to the outlet 132, and the vacuum pump 150 vacuums the plasma generating container 130 so that plasma can be formed in the plasma generating container 130. Make it.

The radio wave generator 110 is connected to the impedance matching unit 120, and generates a power of 60 ~ 100 kHz, and the radio wave generated therein is controlled by the impedance matching unit 120 to control the plasma The plasma is stabilized in the generating vessel 130.

The heating pipe penetrates the inside of the plasma generating vessel 130 in which the induction coil 140 is wound outside. 210, a storage tank 220 connected to the heating pipe 210, and a circulation pump 230 positioned at one side of the storage tank 220 and connected / installed to the heating pipe 210. .

The heating pipe 210 is to transfer the water in the storage tank 220 by the circulation pump 230, in a zigzag or corrugated pipe (or heat dissipation tube) shape in the plasma generating vessel 130 to enlarge the heat exchange area Formed. At this time, the heating pipe located in the plasma generating vessel 130 is installed to be located on both sides with respect to the plasma generating portion for effective heat exchange. That is, the heating pipe 210 penetrates one side of the plasma generating vessel 130, and the heating pipe penetrating one side of the plasma generating vessel 130 passes again through another side of the plasma generating vessel 130. Thus, the water in the heating pipe rises first in the plasma generation vessel by the heating pipe passing through one side of the plasma generation vessel 130, and the water in the heating pipe in which the temperature is first increased is another side of the plasma generation vessel.
