Electric boiler comprising heat exchanging reactor for generating an electric arc and a method of operation thereof {Electric boiler comprising heat exchanging reactor generating electric arc and operating method}

The present invention relates to an electric boiler, and more particularly to an electric boiler capable of producing a large amount of hot water by generating an electric arc in the aqueous solution of the ion-bonding compound.

In general, a boiler for producing hot water for heating is divided into electric, gas, petroleum, etc. according to the type of heat source, and is classified into a heater pump type or a heater heating type according to the heating method.

The heater pump type is a method of heating hot water through heat exchange with the heat generating portion (condenser) of the refrigeration cycle, the heater heating type is a method in which the heating element directly heats the hot water.

Heaters of the heater heating type include sheath heaters, PTC, a kind of semiconductor element, and lamp heaters. Among them, the siege heater is made by enclosing a heating wire together with an insulated body in a pipe such as stainless steel, so that high heat can be obtained and its life is long.

However, when the size heater is used for large-scale heating or mass production of hot water, there is a problem of enormous power costs.

Recently, an electric boiler has been introduced that heats an aqueous solution by flowing an electric current by directly immersing an electrode in an aqueous electrolyte solution. However, this method is similar to the conventional electrolysis method, so that the electrode is dissolved during the reaction, so it is not applied to commercialization facilities, and when used in large-capacity equipment, there is a problem that excessive power costs occur.

On the other hand, the heating device using gas or oil is not free from environmental problems due to the large amount of carbon dioxide and pollutants generated during the ignition process.

The present invention has been made to solve the above problems, and an object thereof is to provide a high-efficiency electric boiler that can produce a large amount of hot water at a minimum power cost and does not generate pollutants or carbon dioxide.

The present invention, in order to achieve the above object, a reaction tank having a reservoir; It is stored in the reaction vessel, the sodium chloride aqueous solution of the weight ratio of water and sodium chloride 1: 0.15 ~ 0.35; It is installed through the reactor to generate an electric arc (electric arc) inside the aqueous solution of sodium chloride, one end is connected to the external commercial power source and the other end is nickel steel is immersed apart from each other in the aqueous sodium chloride solution ( a plurality of electrodes of steel) material; A heating pipe installed inside the reaction tank and having a moving passage of a heating medium therein; An electric boiler comprising a heat storage means connected to one end of the heating pipe through a first pipe, and connected to the other end of the heating pipe through a second pipe, and storing or flowing a heated heating medium while passing through the heating pipe. to provide.

The electric boiler, the temperature sensor for detecting the temperature of the heat medium stored or flowing in the heat storage means; It may further include an aqueous solution temperature control means for selectively blocking the connection of the plurality of electrodes and the commercial power supply by feeding back the detection result of the temperature sensor.

In another aspect, the present invention, (a) setting the target temperature of the aqueous solution and the target temperature of the heating medium stored or flowing in the heat storage means; (b) connecting the commercial power supply to the electrode to generate an electric arc inside the aqueous solution; (c) operating the circulation pump after the electric arc is maintained or after the temperature of the aqueous solution reaches a target temperature, forcing the heating medium into the heating pipe; (d) storing or flowing the heated heating medium while passing through the heating pipe; (e) turning off the electrical connection between the commercial power supply and the electrode when the temperature of the aqueous solution reaches a target temperature, or stopping the operation of the circulation pump when the temperature of the heat medium reaches the target temperature. Provide a method of operating the boiler.

According to the present invention, since the power consumption of the heat exchange reactor used as the heat source is sharply lowered after the electric arc occurs, it is possible to produce a large amount of hot water at a very low power cost.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a block diagram of an electric boiler according to an embodiment of the present invention, a heat exchange reactor 100 used as a heat source for heating, a heat storage tank 200 for storing hot water heated in the heat exchange reactor (100). ).

As illustrated in FIG. 1, the heat exchange reactor 100 includes at least a reaction tank 10 having a storage space, an aqueous solution 20 of an ion-bonding compound stored in the reaction tank 10, and the aqueous solution 20. It includes a plurality of electrode rods 30 which is partially immersed.

In the present invention, the reaction tank 10 made of stainless 304L material is used, but the material of the reaction tank 10 is not necessarily limited thereto, and may be made of another metal material or a synthetic resin material. In addition, the capacity or size of the reactor 10 may be appropriately selected according to the capacity of the heating target.

In particular, the heat exchange reactor 100 according to the embodiment of the present invention generates and maintains an electric arc inside the aqueous solution 20, as shown in the photograph of FIG. There is an advantage that can be greatly improved. This is because the amount of current consumed since the electric arc occurs inside the aqueous solution 20 is drastically reduced.

In addition, the electrode used in the conventional low-temperature electrolysis device is mainly made of copper, carbon, platinum, etc., if an electric arc is generated by applying a commercial power source to the electrode of such a material, the electrode may be damaged in an instant due to electric shock. It was found to be impossible.

However, according to the experiment, if the weight ratio (wt%) of sodium chloride (NaCl) to water is 0.15 to 0.35 in the sodium chloride aqueous solution, the electrode 30 made of nickel steel (nickel steel), the reaction is stable even after the electric arc occurs In addition, damage to the electrode 30 did not occur.

Therefore, when the heat exchange reactor 100 of the present invention is used as a heat source, it is possible to secure a high temperature heat source with very low power consumption by continuously maintaining an electric arc inside the reactor 10.

It is not clear why the arc is generated in the aqueous solution 20. However, when the electrode 30 is immersed in pure water, the water is heated and the arc is not generated. It is analyzed that an arc in the form of a fireball is generated by accumulating fine sparks continuously generated between the charged ions and the electrode rod 30.

In addition, it is not clear why the power consumption sharply decreases after the occurrence of the arc. However, in the case of the metal conductor, the electrical resistance of the aqueous solution 20 increases due to the high temperature arc in view of the fact that the electrical resistance increases rapidly as the temperature increases. Guessed by.

On the other hand, if the weight ratio of sodium chloride is less than the above-mentioned criteria, the electric resistance reaction is weak and no electric arc occurs. If the weight ratio is larger than this, even when the nickel steel electrode 30 is used, the explosive electric power is commercially available (220V, 380V). The resistance reaction caused melting or burning of the electrode.

This aqueous sodium chloride solution 20 is stirred for 40 to 60 minutes at 650 ~ 750 RPM in a stirrer and then used to stabilize for 24 hours.

Two electrodes 30 may be used when connected to a single-phase power supply, and three electrodes may be used when connected to a three-phase power source. The heat exchange reactor 100 of FIG. 1 shows a state in which three electrode rods 30 are installed to be connected to a three-phase power source (R, S, T) having a reference voltage of 380V. When the capacity of the reactor 10 is large, two or more pairs of electrode bars 30 may be provided.

The electrode rod 30 is installed to penetrate the reaction vessel 10, and an insulating fixing member 34 such as rubber packing is installed at the boundary with the reaction vessel 10. In particular, when using a metal reaction tank 10, the electrode 30 should be installed so as not to contact the reaction tank (10). At the end of the electrode rod 30 exposed to the outside of the reactor 10, a connection terminal 32 for power connection is formed.

An upper portion or a side upper portion of the reactor 10 connects an aqueous solution injection tube 18 for introducing an aqueous solution 20 and a gas discharge tube 14 capable of discharging gas such as air filled therein. The gas discharge pipe 14 may be provided with an overpressure safety valve 15 that automatically opens when the internal pressure of the reaction tank 10 exceeds the set pressure. A drain valve 19 for discharging the aqueous solution 20 is connected to the bottom or lower side of the reactor 10.

In addition, one side wall of the reaction tank 10 is provided with a temperature sensor 16 for automatically controlling the temperature of the aqueous solution (20). In addition, an emergency temperature sensor 17 may be installed to cut off power when overheated.

On the other hand, the heating pipe 80 is connected to the heat storage tank 100 in the reaction tank 10 is installed. The heating pipe 80 is in the form of a spiral coil having a length of about 200m. The upper end of the heating pipe 80 is connected to the outlet pipe 11 connected to the upper surface or the upper side of the reaction tank 10, the lower end of the heating pipe 80 is connected to the bottom or lower side of the reaction tank 10 Is connected to the tube (12).

Meanwhile, one end of the first pipe 252 for transferring hot water heated while passing through the heating pipe 80 to the heat storage tank 200 is connected to the water outlet pipe 11, and the other end of the first pipe 252 is heat storage. It is connected to the upper portion or the upper side of the tank 200.

In addition, the inlet pipe 12 is connected to one end of the second pipe 254 for transferring the water stored in the heat storage tank 200 to the heating pipe 80 of the reaction tank 10, the second pipe 254 The other end is connected to the bottom or side surface of the heat storage tank 200. In particular, the second pipe 254 is provided with a circulation pump 260 for pumping the water of the heat storage tank 200 to the heating pipe (80).

The reactor 10 is preferably installed inside the case 50 for convenience of transportation and installation. The case 50 is preferably a metal material capable of supporting the load of the reaction tank 10, but is not necessarily limited thereto. However, when the reaction tank 10 is a metal material, the reaction tank 10 and the case ( 50) shall be installed so as to be electrically insulated.

In particular, an insulating member should be interposed between the lower surface of the reaction vessel 10 and the bottom surface of the case 50. For example, when fixing the reaction tank 10 to the bottom of the case 50, the protrusion 52 formed on the lower surface of the reaction tank 10 is inserted into the fixing rib 56 formed on the bottom of the case 50, It is preferable to interpose the buffer insulating rubber 54 between the fixing rib 56 and the protrusion 52.

The upper surface or the side of the case 50 may be provided with a monitoring window 51 that can visually check the state of the reaction tank (10). The water outlet pipe 11, the water inlet pipe 12, the drain valve 52, the aqueous solution injection pipe 18, the gas discharge pipe 14, and the like extend through the case 50 to the outside.

On the other hand, the side of the case 50 is provided with a control panel 70 including an aqueous solution temperature control means 71, the room temperature control means 74 and the like.

Aqueous solution temperature control means 71 serves to selectively open and close the connection between the commercial power source and the electrode 30 installed in the reaction vessel (10). That is, by feeding back the detection result of the temperature sensor 16 to selectively cut off the power supply to each electrode 30 to maintain the temperature of the aqueous solution 20 to the target temperature, the user to the control panel 70 Input means (not shown) for setting a target temperature of the aqueous solution 20 should be installed.

The indoor temperature control means 71 serves to change the target temperature of the aqueous solution temperature control means 71 by feeding back the detection result of the indoor temperature sensor 73. That is, when the aqueous solution 20 is used as a heat source such as a boiler, for example, if the indoor temperature is lower than the set temperature, the target of the aqueous solution 20 set in the aqueous solution temperature control means 71 to increase the indoor temperature. Serves to change the temperature to a higher temperature.

In addition, the control panel 30 may be provided with an emergency power cut-off means 72 that cuts off the power supply when the emergency temperature sensor 17 detects an overheating temperature.

On the other hand, the heat storage tank 200 is connected to the hot water supply pipe 210 for supplying hot water to the outside and the replenishment water injection pipe 230 for replenishing water into the heat storage tank 200. The supplementary water injection pipe 230 is provided with a water level control valve 232 that is opened and closed by a water level sensor installed inside the heat storage tank 200.

In addition, the temperature sensor (not shown) in the heat storage tank 200 to feed back the hot water temperature inside the heat storage tank 200 to adjust the target temperature of the aqueous solution temperature control means 71 or to control the power of the heat exchange reactor 100. It is desirable to install it.

In addition, the pressure control valve 220 for pressure control is installed on the upper surface portion of the heat storage tank 200, the monitoring window 240 to check the interior of the heat storage tank 200 may be installed.

Hereinafter, the operation of the electric boiler according to the embodiment of the present invention will be described with reference to the flowchart of FIG. 3.

First, the sodium chloride aqueous solution 20 of the above-mentioned concentration is filled in the reaction tank 10, and for example, R, S, and T terminals of a three-phase power source are connected to each electrode 30.

Next, the target temperature of the aqueous solution 20 is set in the aqueous solution temperature adjusting means 71. The temperature of the aqueous solution 20 may be manufactured to be set arbitrarily by the user, or may be set to a specific temperature in the manufacturing process. (ST11)

Subsequently, when the operation switch (not shown) is pressed, electric power is supplied to each electrode 30, and the temperature of the aqueous solution 20 gradually increases while the conductive sodium chloride solution 20 generates resistive heat. The amount of current applied in this process also increases gradually. (ST12, ST13)

However, when the sodium chloride aqueous solution 20 of the above-described concentration is heated to about 80 ° C., an electric arc is generated between the electrodes 30, and thus the flame inside the aqueous solution 20 as shown in FIG. 2. A sphere is created and maintained.

In particular, power consumption begins to decrease after the arc occurs.

That is, in the process of raising the aqueous solution 20 from room temperature to about 80 ° C., the current consumption increased from about 10A to about 50A initially, but after the arc occurred, the current consumption gradually decreased, and when the aqueous solution 20 began to boil, It was confirmed that the level is lowered to 10A. Therefore, if the target temperature is set at a level of about 95 ° C. to 99 ° C., which is the temperature just before the aqueous solution 20 boils, the water in the heating pipe 80 can be heated with minimum power consumption.

According to the conventional method using the electrode, there is no phenomenon that the amount of current decreases because no arc occurs even after heating for a long time. (ST14, ST15)

After the aqueous solution 20 reaches the target temperature, the circulation pump 260 is operated to pump water from the heat storage tank 80 into the heating pipe 80, and passes through the heating pipe 80 having a length of about 200 m. The heated hot water is recovered to the heat storage tank 200 via the water outlet pipe 11 and the first pipe 252.

At this time, when the hot water temperature of the heat storage tank 80 reaches the target temperature (for example, 80 ℃), the aqueous solution temperature control means 71 cuts off the power supply to the electrode 30 and stops the operation of the circulation pump 260 Can be set to stop.

In addition, when the hot water temperature of the heat storage tank 80 is lowered below the reference temperature (for example, 70 ℃), the aqueous solution temperature control means 71 resumes the power supply to the electrode 30 and the operation of the circulation pump 260. Can be set to

On the other hand, the circulation pump 260 may be operated irrespective of the temperature of the aqueous solution 20, but if the cold water is pumped into the heating pipe 80 by operating the circulation pump 260 before the arc is generated, the aqueous solution (20) The arc is delayed at the time of), and there is a fear that excessive power is initially consumed. Therefore, after the arc is generated in the aqueous solution 20 or the temperature of the aqueous solution reaches the target temperature (about 95 ℃ or more), it is more preferable to perform the heat exchange by operating the circulation pump 260. However, the present invention is not necessarily limited thereto, and thus a configuration for operating the circulation pump 260 from an initial operation is not excluded. (ST16)

According to the experiment, the 380V commercial power supply (R, S, T) was connected to the three electrode rods 30 of the heat exchange reactor 100, and the operation was performed while filling the heat storage tank 200 with 200 liters of cold water at about 6 ° C. When the water in the heat storage tank 200 is heated to 80 ℃ in about 23 minutes.

On the other hand, in the above described the electric boiler of the method of storing the hot water heated in the heating pipe 80 of the heat exchange reactor 100 in the heat storage tank 200, the heating pipe 80 is directly connected to the heating pipe for heating Hot water can also be used for floor heating. In this case, a fluid other than water may be used.

In addition, it is also possible to extract the heated aqueous solution 20 and supply it directly to a heating pipe without installing the heating pipe 80 inside the reaction tank 10 of the heat exchange reactor 100.

In addition, although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment and may be modified or modified in various forms. By the way, if the embodiment modified or modified as described also includes the technical spirit of the present invention described in the claims to be of course belongs to the scope of the present invention.
