  Hereinafter, the superheated steam delivery device according to the embodiment of the present invention will be described.

FIG. 1 shows a perspective view of a superheated steam delivery device according to an embodiment of the present invention.
As shown in FIG. 1, a heating duct 11 is provided in the superheated steam delivery device 10 according to the embodiment of the present invention, and the heating duct 11 is formed by an air feeding portion 12, a heating steam delivery portion 13 and a body portion 14. Then, the air E is fed from the feeding port 12 a of the air feeding unit 12, and the superheated steam F is fed from the sending port 13 a of the superheated steam sending unit 13.
The air E to be fed from the inlet 12 a of the air feeding unit 12 is sent from a separately installed blower fan or compressor.
The electric heater unit 16 and the injection nozzles 15a and 15b shown in FIG. 2 are provided in the body portion 14 of the heating duct 11, and the electric heater unit 16 receives the air E from the air inlet 12a of the air inlet 12. The jet nozzles 15 a and 15 b heat the mist K to the air E from the air inlet 12 a of the air inlet 12, and the superheated steam F is delivered from the heating duct 11.
An opening 17 for supplying a mist to the injection nozzles 15a and 15b from the outside through an inlet pipe is provided on the side surface of the body portion 14.

FIG. 2 shows a longitudinal sectional view of the superheated steam delivery device according to the embodiment of the present invention.
As shown in FIG. 2, the superheated steam delivery device 10 according to the embodiment of the present invention is provided with a heating duct 11.
The body portion 14 of the heating duct 11 is provided with the electric heater unit 16 and the injection nozzles 15a and 15b, and the air E is fed from the feeding port 12a of the air feeding section 12 and the delivery port of the superheated steam delivery section 13 Superheated steam F is delivered from 13a.

In the electric heater unit 16, a coil-type electric heater 16b is provided inside a cylindrical tubular portion 16a whose bottom is closed. Since the coil-type electric heater 16b is provided in a sealed manner in the cylindrical tubular portion 16a in which the bottom formed of a heat transfer material is closed, it also directly contacts the spray mist K from the spray nozzles 15a and 15b. Therefore, the air E can be effectively heated to prevent damage and deterioration. Since the cross section of the body portion 14 of the heating duct 11 has a rectangular shape, the mounting of the electric heater unit 16 in the vertical direction is facilitated, and heat conduction is also performed effectively.
In addition, although the coil type electric heater 16b is provided in the electric heater unit 16 inside, it can be made various shapes, such as not only a coil type but a straight line shape, and not only an electric heater but various kinds. A heater can also be used.

The injection nozzles 15 a and 15 b are provided inside the heating duct 11 together with the electric heater unit 16 to inject the supplied mist from the outside. Therefore, the mist can be effectively mixed with the air supplied from the outside by the sprayed mist K.
Although the injection nozzle 15a is provided at the center of the body portion 14 of the heating duct 11 and the injection nozzle 15b is provided on the air delivery side of the body portion 14 of the heating duct 11, only the injection nozzle 15a may be used alone. Alternatively, an injection nozzle may be provided on the air inlet side of the body portion 14 of the heating duct 11.
In addition, an air compressor 18 may be provided on the air feeding side of the body portion 14 of the heating duct 11 to further increase the pressure of the feeding air.

  As described above, in the superheated steam delivery device 10 according to the embodiment of the present invention, the heating duct 11 is formed of the air feeding portion 12, the superheated steam sending portion 13 and the body portion 14, and the air feeding portion 12 receives the air E Since the air E is heated by the body portion 14 and the mist K is injected from the injection nozzles 15a and 15b so that the superheated steam F is delivered from the superheated steam delivery unit 13, the structure is simple and effective and easy Delivery of superheated steam.

Although the superheated steam delivery device 10 delivers air E and delivers superheated steam F, it is preferable that the air delivery unit 12 further delivers high-pressure air and delivers high-pressure superheated steam. The air E can also be heated to a higher temperature to deliver high pressure superheated steam. Of course, high-temperature and high-pressure superheated steam can also be delivered.
Furthermore, steam or mist may be mixed into the air E, and the electric heater unit 16 may be heated to deliver superheated steam.

  The superheated steam delivery device according to the present invention is to feed air from the outside, heat the fed air, inject a mist into the fed air, and deliver the superheated steam, so that various kinds of heating, washing and drying are performed. It can be used for various applications, and of course it can be widely applied to repair and reconstruction of factory equipment and buildings.
