The specific embodiment
For narration in more detail, based on description of drawings the present invention.
Fig. 1 is the diagrammatic illustration figure of the superheated steam producing device of the expression embodiment of the invention, and Fig. 2 is the embodiment of the non-calandria of expression gas permeability.
Among the figure, the 1st, cylindrical body, 1a is an end of cylindrical body 1,1b is the other end of cylindrical body 1, the 2nd, the distributing nozzle of injection water, the 3rd, the ejiction opening of superheated steam.Other 4 is gas permeability heated objects, 5 magnet exciting coils, the 6th, lining material, the 7th, conduit, the 8th, pressurized steam generating means, the 40th, the anti-metallic plate that bounces.In addition, HV is a superheated steam, and V1, V2 are switch valves, and V3, V4 are non-return valves.
Among Fig. 1, an end 1a of the cylindrical body of making at conductor material 1 has the distributing nozzle 2 of injection water, has the ejiction opening 3 of superheated steam at other end 1b.
The lining material 6 that the outer peripheral face of cylindrical body 1 is made with castable refractory body pottery covers and the quilt thermal insulation.And the outer peripheral face of this pottery system lining material 6 is wound with the magnet exciting coil 5 by high frequency electric, and this magnetic coil 5 is connected on the not shown high frequency electric power supply.
In addition, the gas permeability heated object 4 that the filling conductor material is made in the cylindrical body 1 (is the spheroid (with reference to Fig. 2 (A)) that stainless steel is made among Fig. 1, electromagnetic induction heat release by magnet exciting coil 5 is heated, water by herein or water vapour are by high temperature heating becoming superheated steam HV, from ejiction opening 3 ejections of other end 1b.The 40th, the anti-metallic plate that bounces.
In addition, the distributing nozzle 2 of injection water that is arranged at an end 1a of cylindrical body 1 is connected on the water-delivery pump P by conduit 7, and is connected on the pressurized steam generating means 8.
For from the distributing nozzle 2 of injection water to cylindrical body 1 spray water, close the conduit switch valve V2 midway that is arranged at from pressurized steam generating means 8, open switch valve V1.In addition,, open switch valve V2, also open switch valve V1 for spray water and pressurized steam in cylindrical body 1.In addition, V3 and V4 are non-return valves.
Among the present invention, spray water and steam from an end 1a of the cylindrical body 1 of filling the gas permeability heated object 4 that conductor material makes in cylindrical body, secondly water or water vapour are by being filled in the above-mentioned gas permeability heated object 4 of this cylindrical body 1.At this moment, above-mentioned gas permeability heated object 4 is heated by the electromagnetic induction heat release of magnet exciting coil, therefore can the high temperature heating water or water vapour by herein, thereby become superheated steam HV and spray from the ejiction opening of the other end 1b of cylindrical body 1.
In addition, the 40th, the anti-metallic plate that bounces.The above-mentioned anti-metallic plate 40 that bounces prevents that the above-mentioned gas permeability heated object 4 that is filled in the cylindrical body 1 from flowing to outside the cylindrical body 1.In addition, the 41st, anti-bounce metallic plate and neutralize part, preferably heat conductivity height, the good member (such as being copper or silvery) of hear resistance, this occasion is made of copper, double panel structure up and down, forms the structure of joining rack bridge plate 41c between plate 41a and the plate 41b.And the outstanding long leg 41d that is provided with of slave plate 41b, and insert between the gas permeability heated object 4.
Thus, the high heat of gas permeability heated object 4 is constantly passed to long leg 41d and is kept 41b, 41c, and the high temperature of 41a can not reduce from the temperature of the injection water of distributing nozzle 2 ejection of injection water, guarantees vaporize at once and unceasingly.
The right also high-frequency induction heating of injection water is filled in the above-mentioned gas permeability heated object 4 in this cylindrical body 1, compares and import the situation that water vapour heats again in cylindrical body 1, can generate the superheated vapours of several about 10 times～1000 times amounts.Therefore can be easily make the ejection of high pressure superheater water vapour from the other end of cylindrical body.
Promptly, 22.4 the heavy 18g of the water vapour that rises, the heavy 18g of the water of 18ml, if therefore in cylindrical body 1, spray the water of 18ml in theory, then can generate 22, the water vapour of 400ml, the result is 22, therefore 400ml ÷ 18ml 1240 sprays and the occasion that adds hot water generates about 1200 times a large amount of pressurized steam than the occasion that imports and add hot water and steam.Therefore, the pressure of the pressurized steam of generation is very high.
In addition, water or water vapour by in the cylindrical body 1 time, the gas permeability heated object 4 that contact has been heated, thus further be heated as superheated steam, expand gradually and near the discharge side of cylindrical body 1.
Cut off the power supply of magnet exciting coil 5 even the temperature in the cylindrical body 1 rises, gas permeability heated object 4 also is in the condition of high temperature, and the temperature that turns cold in the cylindrical body 1 by gas permeability heated object 4 descends, and therefore cooling also needs the time.
As gas permeability heated object 4, can use the metal of the weak magnetic of the ferromagnetic metal of iron or the like, stainless SUS430SUS403, nickel, titanium or the like, also can use the carbon ceramics of carbon, carborundum or the like in addition.
As the conductor heating material of gas permeability heated object 4, magnetic metal material preferably, the hard magnetic material is more suitable.
With regard to gas permeability heated object 4, must be that steam is waltzed through, can use clava, wire rod, sheet material, cellular material, restiform bodies, spheroid, hollow sphere or the blocks of indefinite shape etc.Also can penetrate thereon open-work is set.
Embodiment:
Use superheated steam producing device shown in Figure 1 (wherein, using the hollow sphere that is provided with peristome shown in Fig. 2 (b) everywhere as gas permeability heated object 4), water generates superheated vapour.
At first, the distributing nozzle 2 usefulness 4～6kg/cm of the injection water in the end 1a who is configured in cylindrical body 1
2, 6～10kg/h expulsion pressure spray water.At this moment, do not use pressurized steam generating means 8, so switch valve V2 is for closing, switch valve V1 is for opening.
The internal diameter of cylindrical body 1 is 20cm, the long 40cm of being, heated object uses the ferrite-group stainless steel (SUS430) of magnetic metal material, uses the carbon steel goods in the preferred example, and cylindrical body 1 is used austenite stainless steel (SUS304) goods.
In addition, supplying with magnet exciting coil 5 frequencies with 25～30kw/h is the high frequency electric of 20kHz.
Consequently, continue the hyperthermia and superheating water vapour HV of 320 ℃ of ejections from the ejiction opening 3 of superheated steam.
Utilizability on the industry
According to the present invention, from an end of the cylindrical body of filling the gas permeability heated object that conductor material makes to Injection water or water and water vapour in the tube, high-frequency induction heating is filled in above-mentioned in this cylindrical body then The gas heated object is compared with the occasion that importing water vapour in cylindrical body heats again thus, can produce Therefore the superheated vapours of several about 10 times～1000 times amounts can be from the other end of cylindrical body easily Make the ejection of high pressure superheater water vapour.
And the hyperthermia and superheating water vapour that uses the present invention to obtain can be used for wheat, buckwheat, beans etc. Etc. cereal, the sterilization of strawberry, tomato etc. fruit or vegetables perhaps is used for roasted coffee beans or tea Etc., and be used for from contaminated soil volatile injurant (such as the nuisance of organochlorine system) Gasification separation and produce purification of contaminated soil etc.
