Due to the improvement of living standards, interest in health, and the activation of media such as broadcasting, modern people show great interest in health food.

Humans can not live without water and salt. Among them, researches on water and purification methods have made many improvements, and every household uses a water purifier and can easily buy and eat drinking water.

However, salt has different properties from water, and it is difficult to process it. It is not easy to process because of harmful gas ejection during processing. Most of salt is consumed by adding to food except special case.

In the course of the evolution of salt, natural salts such as sun salts and flames are used, and salt is roasted and used.

It is not easy to purify the salt and it is difficult to purify the salt and it is also difficult to raise the temperature when the salt or bamboo salt is baked but the fire or the electricity is heated. It is not easy to remove the toxic substances contained in the salt by raising the temperature and the economical efficiency due to the high cost of energy. However, in the process of burning, dioxins, wood tar and other harmful ingredients are limited.

Here, the molten salt (molten salt) refers to a molten salt commonly used for molten salt electrolysis. The molten salt refers to a molten salt of a halide, and an oxyacid such as a sulfate, a nitrate, or a carbonate And ionized liquid ionized, and the conductivity is larger than that of the aqueous solution. Mixed molten salt of binary and ternary can be made easily.

Therefore, conventionally, the salt can be heated and roasted or baked in a short time, or the salt itself is melted using the microwave melting furnace, and the salt is baked, melted or boiled (dissolved), and harmful substances in the salt are discharged, (Korean Patent Publication No. 10-1320764) for drying heat treatment for removing impurities of a salt and removing impurities using a new type of microwave capable of producing a salt beneficial to health, And a salt processing apparatus using microwave and salt produced therefrom (Korean Patent Laid-Open Publication No. 10-2014-0010559) have been proposed.

Among the above-mentioned prior arts, a baked salt manufacturing apparatus (Korean Patent Registration No. 10-1320764) for drying and heat-treating a salt to remove impurities using microwave has a crucible for containing main salt and a detachable crucible cap A magnetron is connected to the outside of the main body through a waveguide, a heat insulating material insulating wall is provided on the inside of the main body, a salt charging port for supplying salt into the main body on the upper surface or side surface of the main body, a combustion gas discharging port for discharging gas, , And a molten salt discharge port for discharging molten salt is wound around the lower side of the main body side.

A salt processing apparatus using a microwave and a salt manufactured by using the same (Korean Patent Laid-Open Publication No. 10-2014-0010559) is a salt processing apparatus using a microwave, comprising: a body case; A heating chamber mounted in the body case to apply heat thereto; A heating tube which is disposed transversely to the central portion in the heating chamber and is made of a metallic material; A heating element which surrounds the outer surface of the heating tube and conducts the heated heat; A heat insulating material which surrounds the heating body to prevent the heat transmitted through the microwave and being heated from flowing out to the outside; A plurality of magnetrons installed on upper and lower surfaces of the body case to guide microwaves to the heating tube inside the body case through a waveguide to radiate the microwaves; A salt injecting means installed above one side of the body case for injecting salt into the heating tube; And discharging means for discharging the salt discharged from the heating tube while surrounding the other side of the body case.

The second configuration is a rectangular body case; A heating chamber forming an interior of the body case; An air inlet and a gas outlet respectively installed from the left and right sides of the body case to the heating chamber; A plurality of magnetrons installed on the body case to radiate microwaves toward the heating chamber through waveguides; A crucible provided on the bottom surface of the heating chamber and composed of a plurality of quadrangular SiC-based materials arranged in a plurality of openings so as to contain and process the salt; And a plurality of nano carbon heaters installed to radiate far-infrared rays from the upper surface of the heating chamber toward the crucible.

However, the above-described conventional salt processing apparatuses using microwaves are merely apparatuses for processing salt only, and they can be used in other devices (for example, a steam turbine and a generator are driven to generate electricity by using waste heat generated in the processing of salt) Or a device for providing cold water by heating with hot water, etc.), the compatibility and usability of the device itself are deteriorated, and unnecessary energy is wasted.

In addition, there is a problem that second harm is caused by electromagnetic waves which are necessarily generated when the salt is heated by using the magnetron, and since it is configured to be driven only by a commercial power source, a large amount of electricity is consumed due to the salt processing, There is also a problem of unnecessarily wasting resources, especially in the summer when electricity consumption is very high.

At this time, the solar cell 10 is installed in an outdoors where sunlight is well irradiated and has a form in which a number of modules capable of sufficiently generating electric power necessary for driving the salt continuous melting furnace 30 are assembled into one module. The solar energy is continuously converted into electric energy in the daytime and supplied to the control panel 20 side.

In addition, the salt supply tank 170 is provided with a plurality of gel-salt temporary pipes through a gel-salt transfer pipe 90 provided with a general salt input port on one side of a tank having a predetermined volume and a salt- The gaseous salt primarily taken out from the seawater is transferred through the plurality of steam boilers 80 including the general salt which is connected to the storage tank 190 and is input by the operator directly or through the automatic injector, And stores it.

The screw lift 180 is installed between the salt supply tank 170 and the hopper 38 of the salt continuous melting furnace 30 and drives the motor 181 driven in response to the drive signal of the control panel 20 And serves to transfer the salt stored in the salt supply tank 170 to the salt continuous dissolution 30 through the sea screw 182.

In addition, the control panel 20 receives the DC voltage outputted while the sunlight is well irradiated by the plurality of solar cells 10, converts the DC voltage into an AC voltage through the inverter 21, And then applies it to the magnetrons 34 provided in the salt continuous melting furnace 30 to be described later, as well as to perform the overall control function of the system to which the present invention is applied.

3 to 7, the salt continuous melting furnace 30 basically comprises a closed chamber 31, a heat insulating pipe 32, a plurality of magnetrons 34, a plurality of silicon carbide heating pipes 35, The molten salt discharge port 39 is directly connected to the molten salt storage tank 40 to be described later with the upper and lower thermal insulation plates 36 and 37, the hopper 38 and the molten salt discharge port 39 .

When a high voltage is output from the control panel 20, the plurality of magnetrons 34 are driven to generate a microwave of, for example, 2,450 MHz / sec. Thus, Since the silicon carbide heating pipe 35 is heated by induction heating, the silicon carbide heating pipes 35 generate heat in a temperature range of 800 to 900 ° C, for example, And discharging the molten salt continuously to the molten salt storage tank 40 side.

At this time, the closed chamber 31 of the constituent elements of the salt continuous melting furnace 30 is formed into a cylindrical or polygonal shape having a predetermined diameter, length and volume by using a metal plate (for example, a stainless plate or the like) A plurality of magnetron mounting holes 31a are formed at predetermined intervals on the outer side of the chamber 31, and the upper and lower openings are closed to prevent microwave leakage.

The chamber 31 is further provided with a chamber pressure check valve 31c so that the air in the hollow portion 31b formed between the inner surface of the chamber 31 and the outer surface of the heat insulating pipe 32, The chamber pressure check valve 31c is automatically opened to lower the pressure in the chamber 31 when the chamber 31 is inflated to a predetermined pressure set on the pressure check valve 31c so that the chamber 31 is damaged or damaged by the expansion pressure, It is possible to prevent breakage.

4, a mesh net 31d having a mesh of 3 mm or less is provided to prevent leakage of the microwave, and the chamber pressure check valve 31c is connected to the chamber pressure check valve 31c through the chamber pressure check valve 31c It is possible to prevent the microwave diffracting the hollow portion 31b from being blown off by the mesh net 31d of the mesh of 3 mm or less when the inside air is discharged and to prevent the microwave from leaking to the outside, .

The heat insulating pipe 32 is formed to have a cylindrical or polygonal shape corresponding to the shape of the chamber 31 and has an outer diameter smaller than the inner diameter of the chamber 31, ). ≪ / RTI >

Such a heat insulating pipe 32 is inserted into the chamber 31 so as to have a shape in which a part of the upper and lower ends protrude to the outside in a state in which a plurality of silicon carbide heating pipes 35 to be described later are built in, And a hollow portion 31b having a predetermined height is formed between the inner surface of the chamber 31 and the outer surface of the heat insulating pipe 32. The hollow portion 31b is formed in the chamber 31 through a plurality of supporting members 33, .

The heat insulating tube 32 having the above structure is discharged from the waveguide 34a of the magnetron 34 and then diffracted by the microwave diffracted in the hollow portion 31b toward the silicon carbide heating tube 35 And the heat generated in the silicon carbide heating tube 35 is not transmitted to the chamber 31, so that the temperature rise of the chamber 31 can be minimized.

The magnetrons 34 are basically used as a special vacuum tube for controlling the flow of electrons by applying a magnetic field to strongly output microwaves of microwaves. The magnetrons 34 Have a shape in which an end of a waveguide 34a from which microwave is emitted is detachably attached to a magnetron mounting hole 31a of the chamber 31, respectively.

When a high voltage is applied from a high voltage transformer of the control panel 20, the magnetron 34 oscillates a high frequency to generate a predetermined frequency band of a predetermined frequency band (a predetermined frequency band) by a hollow portion 31b formed between the inner surface of the chamber 31 and the outer surface of the heat insulating tube 32 For example, 2,450 MHz / sec).

The microwaves emitted from the magnetrons 34 diffract the hollow portion 31b formed between the inner surface of the chamber 31 and the outer surface of the heat insulating tube 32 and then pass through the heat insulating tube 32, The silicon carbide heating tubes 35 having the absorption function are directly heated by induction.

The ends of the waveguide 34a are detachably attached to the magnetron mounting holes 31a of the chamber 31 as described above so that the magnetron 34 can be detached from the outside of the chamber 31 34) can be simply replaced.

The plurality of silicon carbide heating tubes 35 are obtained through the salt continuous melting furnace 30 by using black silicon carbide (Black SiC) having a specific gravity of 3.12, a melting point of 2,600 to 2,800 ° C. and a hardness higher than that of diamond And is set in the heat insulating pipe 32 by extrusion molding so as to have a predetermined diameter and length in conformity with the input amount of the salt and the melting temperature.

When a microwave of a predetermined band is emitted from the magnetrons 34 corresponding to the output signal of the control panel 20, the plurality of silicon carbide heating tubes 35 are directly heated to 800 to 900 degrees Celsius The inside of the silicon carbide heating pipes 35 having the inclined state at a predetermined angle is gradually heated to be heated by induction heating so that the salt of common salt and the gel state gradually passes through the inside of the silicon carbide heating tube 35 and is automatically melted and converted into a molten salt in a liquid state, And is continuously and automatically transferred to the salt storage tank 40 side.

At this time, the silicon carbide heating pipe 35, so may lead to chlorine (Cl ₂₎ component and the chemical reactions that occur in the course of their nature, the salt melt when using the silicon carbide heating pipe 35 as chlorine (Cl ₂ ) Component and the chemical reaction, which may shorten the life span remarkably.

Accordingly, in the present invention, molybdenum having a property of absorbing microwaves such as silicon carbide is coated on the inner surface of the silicon carbide heating tube 35 to have a predetermined thickness as shown in FIGS. 4 and 5 to mold the molybdenum coating layer 150 6 or 7, a stainless steel pipe 160 coated with a molybdenum coating layer 150 is further installed inside the silicon carbide heating pipes 35. In the process of melting the salt, chlorine (Cl ₂ ) The chlorine (Cl ₂ ) component can be prevented from directly contacting the inner surface of the silicon carbide heating pipe 35, so that the service life of the silicon carbide heating pipe 35 itself can be greatly extended.

The reason why the molybdenum coating layer 150 is applied to the inner surface of the stainless steel pipe 160 is that when the stainless steel pipe 160 is directly installed in the silicon carbide heating pipes 35, There is a fear that the microwave of a predetermined band reflected by the stainless steel pipe 160 is reflected to the chamber 31 side and reflected by the surrounding of the salt continuous melting furnace 30, And there is a risk that damage such as corrosion may occur due to the chlorine (Cl ₂ ) component itself.

The molybdenum has a melting point of 2,450 to 2,620 ° C. and a density of 10.2 g / cm 3. The molybdenum is heated by the microwave to 800 ° C. to 900 ° C. through the silicon carbide heating pipe 35, The shape of the molybdenum coating layer 150 having a strong chemical characteristic to the chlorine (Cl ₂ ) component and thinly coated is maintained when the common salt and the gel type salt are melted through the silicon carbide heating pipe (Cl ₂ ) component that occurs when the salt melts.

Therefore, it is possible to completely prevent the silicon carbide heating pipe 35 or the stainless pipe 160 from being damaged by the chlorine (Cl ₂ ) component, and to prevent the silicon carbide heating pipe 35 or the stainless pipe 160 from being damaged, It is possible to greatly extend the life of the battery.

On the other hand, when the length of the silicon carbide heating tube 35 is long, it may easily bend and the length may be limited.

Accordingly, in the present invention, when the stainless steel pipe 160 having the molybdenum coating layer 150 formed therein is installed in parallel, the silicon carbide heating pipes 35 are formed to a relatively short length, and the stainless pipe 160, The silicon carbide heating pipes 35 having the short length formed on the outer surface of the silicon carbide heating pipes 35 are arranged continuously as shown in the enlarged view of FIG. 6 to maintain the shape thereof by the rigidity of the stainless pipe 160, The heat can be exerted to the desired temperature on the outer surface of the stainless pipe 160.

The heat insulating plates 36 and 37 for the upper and lower caps are installed at the upper and lower ends of the heat insulating tube 32 and are formed as a space portion formed between the silicon carbide heating tubes 35 in the heat insulating tube 32 So that the salt and the molten salt are prevented from entering.

In this case, when the upper and lower heat insulating plates 36 and 37 are provided directly in contact with the lower end portions of the silicon carbide heating pipe 35 in the heat insulating pipe 32, There is a fear that the heat insulating plates 36 and 37 for the upper and lower stoppers may be separated from the upper and lower ends of the heat insulating pipe 32 when the air present in the space portion is expanded.

Therefore, in the present invention, when the upper and lower ends of the silicon carbide heating pipes 35 in the heat insulating pipe 32 are positioned when the heat insulating plates 36 and 37 for the upper and lower stoppers are formed, 36b (37b) are protruded and formed on the rear surfaces of the raw material inflow holes (36a) (37a) without puncturing the silicon carbide heating tubes (36a) When the heat insulating plates 36 and 37 for the upper and lower caps are installed, the respective heating tube insertion rods 36b and 37b are fitted into the inside of the silicon carbide heating tubes 35, A gap is formed between the inner surfaces of the lower closure heat insulating plates 36 and 37 and the upper and lower ends of the silicon carbide heating pipes 35 so that air can flow.

Considering that the heat insulating plates 36 and 37 for the upper and lower caps including the heat insulating tube 32 and the support base 33 are in direct or indirect contact with the silicon carbide heating tubes 35, The silicon carbide heating tubes 35 are heated to a temperature of, for example, 900 to 1,500 占 폚 by molding them into an alumina fiber board having a high melting point of 1,000 to 1,800 占 폚 and a density (kg / m3) of 300 to 600 The heat insulating pipe 32 and the support base 33 and the heat insulating plates 36 and 37 for the upper and lower stoppers are not melted or thermally deformed to maintain their own shape.

The hopper 38 is provided with a screw 38b driven by a motor 38a and is installed in the upper part of the heat insulating pipe 32. The hopper 38 is provided with a screw 38b, And then supplies the regular salt and the gel-like salt to the inside of the silicon carbide heating pipes 35 continuously and uniformly.

The molten salt storage tank 40 is melted through the salt continuous melting furnace 30, (For example, 600 to 800 ° C.), and discharges the molten salt continuously by a predetermined amount through a screw pipe 50 to be described later.

At this time, considering that the molten salt containing the chlorine (Cl ₂ ) component generated in the process of melting the salt is stagnated for a long time in the molten salt storage tank 40, the chlorine (Cl ₂ ) It is preferable to form the molybdenum coating layer 150 with a predetermined thickness as shown in the enlarged view of FIG. 1 on the inner surface, if necessary. When the molten salt is stored for a long period of time, chlorine (Cl ₂ ) can completely prevent the molten salt storage tank 40 from being corroded or damaged.

In addition, considering that the salt continuous melting furnace 30 of the health salt production system to which the present invention is applied can be driven by the power generated in the solar cell 10 only during the day when sunlight is shining, Even if the molten salt storage tank 40 itself is molded into a heat insulating material having excellent thermal insulation and heat shielding property, heat may be discharged to the outside in order to maintain the temperature of the molten salt melted through the continuous melting furnace 30 for a long period of time Therefore, it is preferable that a heat insulating cover (not shown) is additionally provided on the outer surface of the molten salt storage tank 40 to further improve the warmth.

Although not shown in the drawing, in order to prevent corrosion due to salinity in various tanks or pipes in which salt or seawater is desalinated or moved for a long time such as the sea water supply pipe 130 including the inner surface of the steam boiler 80 If necessary, the molybdenum coating layer may be further formed.

On the other hand, the plurality of screw tubes (50) are provided at one end thereof with an opening / closing amount corresponding to the output signal of the control panel (20) to control the amount of molten salt stored in the molten salt storage tank The molten salt is transferred to the interior of the steam boiler 80, and the molten salt is transferred to the steam boiler 80, which will be described later, in order to smoothly transfer the solid salt, which is gradually solidified due to heat exchange with seawater in the boiler 80 And a screw driving motor 53 for generating a power required to rotate the molten salt transfer screw 52 is installed at the other end of the steam boiler And is formed so as to penetrate to the other side.

At this time, considering that the molten salt containing the chlorine (Cl ₂ ) component is also transported for a long time, the screw tubes (50) also have a strong chemical resistance to the chlorine (Cl ₂ ) And a molybdenum coating layer 150 may be further formed on the inner surface of the molten salt storage tank 40 to a predetermined thickness as shown in FIG. 2, as in the case of the molten salt storage tank 40, The screw tube 50 itself is prevented from being corroded or damaged by the chlorine (Cl ₂ ) component contained in the screw tube 50 during the process of being transported along the inside of the screw tube 50 and being cooled and solidified.

The plurality of salt crushers 60 are disposed at the other end of the screw pipes 50 to crush the salt lumps discharged through the screw pipes 50 into a powder having a size suitable for human consumption, To the tank 70 side.

In addition, the plurality of gel salt temporary storage tanks 190 are connected to a salt discharge adjustment solenoid valve 85 (see FIG. 1) by a control panel 20 in a state where the plurality of gel salt temporary storage tanks 190 have a predetermined volume and are respectively installed on the bottom of the gel- Is opened to temporarily store the gel-state salt produced during evaporation of the seawater in the corresponding steam boiler through the gel-salt discharge pipe 86.

At this time, the gel salt temporarily stored in the gel salt temporary storage tanks 190 is supplied to the gel salt transfer pipe 90 by the control panel 20 when the salt transfer pump 91 is operated, It is forcibly transferred to the supply tank 170 side and mixed again with the common salt.

The seawater feed pump 131 is installed on the seawater supply pipe 130 connected in parallel to the seawater inlet pipe 84 of the steam boiler 80, When the solenoid valve 83 is opened and a drive signal is outputted from the control panel 20, the solenoid valve 83 is operated correspondingly and forcibly sends and receives the seawater into the steam boiler 80.

Meanwhile, in the control panel 20, in order to smoothly discharge the gaseous salt generated from the plurality of steam boilers 80, control is exercised to alternately operate.

That is, the electromagnetic valves 83 for adjusting the inflow of seawater, which are respectively installed in the plurality of steam boilers 80, are time-shifted (that is, a time difference in which the seawater in one steam boiler 80 can be mostly evaporated into steam) And the sea water transfer pump 131 is operated to put seawater into the steam boiler 80 until the upper limit water level detection sensor 87 is turned "on ".

Also, since most of the seawater is evaporated into steam by the diverging heat of the molten salt passing through the screw pipe 50, when the gel state salt is formed on the bottom surface and the lower limit level detecting sensor 88 is turned "on " The salt discharge adjustment solenoid valve 85 provided at the bottom of the steam boiler 80 is opened to automatically discharge the gel salt into the gel salt temporary storage tank 190 and then the upper limit water level detection sensor 87 is turned " The salt water can be continuously produced from the seawater by repeating the process of injecting the seawater into the steam boiler 80 until the steam is boiled.
