Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an infrared radiation device, and more particularly to an infrared radiation device that can efficiently irradiate far-infrared rays to chemical substances.

It has been known that certain effects can be obtained by irradiating various chemical substances with infrared rays. However, most polymeric substances, organic substances, and inorganic substances have absorption characteristics in the far-infrared wavelength region even in the infrared rays. Therefore, according to the first law of photochemistry (Grotthus-Draper's law) that only light absorbed by a substance can cause a photochemical reaction, the same light can be irradiated. If so, it is more effective to irradiate more far infrared rays than visible light in order to function as a reaction energy source.

For example, as an example of a polymer combination reaction, a polymerization reaction between an isocyanate and a polyol for producing a urethane resin will be explained. Both aliphatic and aromatic isocyanates have mostly infrared absorption in the 2270α-
There is absorption near 1 due to extremely strong antisymmetric stretching vibration.

Furthermore, absorption of symmetrical stretching vibration is observed near 1350 cm-1, but it is too weak to be utilized.

On the other hand, in the infrared absorption spectrum of boriol, there is absorption of unique OH stretching vibration and OH bending vibration, but these are all sensitive to the influence of substituents, especially hydrogen bonds, and OH
It does not exhibit an independent absorption shape coupled with bending vibration neighboring groups. The infrared absorption spectral ranges of the OH functional group in various states are shown below.

Leaf (free) 3650~3500cm-1 Leaf expansion/contraction vibration 0

m-' Kano Shinkon 1 vibration Kano (chelate type) 320062
500cm-' Leaf stretching vibration Therefore, when a mixed liquid of isocyanate and polyol or a mixed liquid in which the urethane reaction has not completely completed is irradiated with infrared rays of the above wavelength, specific atoms or atomic groups in the molecules corresponding to that wavelength will receive infrared energy. The vibrational state changes from the ground state to the excited state. By doing so, vibrations become more active and molecular collisions become easier, so that the urethane reaction proceeds more quickly and completely.

Infrared rays can also have a great effect on the ecology of plants and animals. Examples of such reactions include a photooxygenation reaction using light using oxygen molecules as an oxidizing agent, and a so-called photosensitized oxygenation reaction that combines light, a sensitizer, and oxygen. For example, as shown in equation 1 below, a 3<Ki sensitizer (3Sens*) transfers excitation energy to oxygen molecules in the ground state to generate excited-multitet oxygen molecules (1o2), which are added to the substrate (photo sensitized oxygenation reaction).

30-50 kcal/mole) generated when a sensitizer and olefins are combined. In addition to synthetic dyes such as rose bengal, eosin, and methylene blue, natural dyes such as chlorophyll and riboflavin are used as sensitizers.

There is an infrared spectral range that is effective for such reactions, and by irradiating living organisms with infrared rays in such infrared spectral ranges, it is possible to activate biological reactions without endangering living organisms. .

Among the effects of light on biological systems, there is a photodynamic effect that consists of changes in constituent substances due to photosensitized oxygenation reactions. A pigment existing in the organism or artificially added serves as a photosensitizer, and is essentially the same as a photosensitized oxygenation reaction. Substances unique to living organisms, especially deoxyribonucleic acid (DNA), have guanine residues,
It is known that tryptophan, tyrosine, histidine, mysteine, and methionine residues undergo changes in proteins. Furthermore, even with long wavelength light (>320 TrL/l), the excited states of 3,4-benzpyrene and furocoumarin react with cytosine and thymine in the ground state, causing photoaddition of nucleobases with other substances. Are known.

In such cases, the reaction rate and reaction rate can be improved by irradiating light energy with a specific wavelength.

Furthermore, it is known that by irradiating biological cells with infrared rays, molecules necessary for cell activity can be excited and activated, improving metabolic balance.

Cell division is controlled by hormonal signals and progresses by activating mitochondrial movement (vibration) and thickening of dyed threads, but infrared irradiation also activates mitochondrial movement. and can activate cell division. Therefore, if it is accompanied by abundant nutrients, it will be possible to promote the growth of those organisms.

Furthermore, it has been studied that infrared rays of 0.72 to 0.75 .mu.m have an effect of inhibiting germination on seeds such as Jasmine and Hotokeza (Jones and Bailey 1956 and Black et al. 1954). Therefore, it can also be applied to the prevention of germination of stored t+ and 'r.

It is also known that living organisms suffer from various disorders when the movement of intracellular substances decreases. In this case as well, movement can be activated by irradiating weakened substances with infrared rays of a specific wavelength from the outside, which can also be used to treat diseases.

Conventionally, for the purpose of accelerating the reaction of molecules, etc., a thermal induction method in which temperature is applied externally, ie, a method using a high-temperature furnace, a constant temperature bath, a high-temperature reactor, etc., has been generally used. Since these methods raise the temperature of the object through convection or heat conduction caused by hot air, their thermal efficiency is very poor, and furthermore, it is not possible to selectively irradiate infrared rays of a desired wavelength.

Moreover, in the case of high-temperature reactors, gas combustion heat or electric heat was used as the heat source. Therefore, in the case of gas, there are problems in the treatment of combustion gas and the risk of explosion, while in the case of electric heat, there are problems in terms of exergy efficiency and power consumption.

In view of these shortcomings of the prior art, the main object of the present invention is to provide an infrared radiation device that can efficiently utilize electrical energy and electrical exergy and selectively irradiate an object with infrared rays in a desired wavelength range. Our goal is to provide the following.

The object of the present invention is to provide a base, an infrared reflective film coated on the base, an infrared generating resistor polymerized on the infrared reflective film, and an infrared ray 9AfJ coated on the resistor. ζ An infrared emitting device characterized by comprising an overtop coat film coated on the emitting film, and a substrate whose inner surface is coated with an infrared reflective film.The inside is divided into two parts by the overtop film. an irradiation stand for an object to be irradiated with an infrared ray provided in a first part of the container, and an infrared ray generator provided in a second part of the container, the infrared ray emitter This is achieved by providing an infrared ray emitting device characterized by having an infrared ray emitting resistor and an infrared ray emitting film coated on its outer surface.

With such a configuration of the present invention, the reactor can be made small-scale and the equipment cost can be reduced, and the energy consumption is also small, and most of the emitted infrared energy is effectively absorbed. Therefore, the reaction rate is high and the reaction time can be shortened. Furthermore, since no combustion gas is generated, workers can work comfortably and no pollution is caused.

Preferred embodiments of the invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of an infrared radiation device according to the invention. The base 512 of this infrared ray emitting device 1 is made of an aluminum plate or a metal plate with a glossy surface made of materials such as AQ, AU, or Rh, and at the same time it deflects most infrared rays and serves as a reinforcing plate for the infrared ray emitting device. There is. This substrate 2 is further coated with an infrared reflective film 3. This infrared reflective film 3 is made by dissolving powder mainly composed of fine stainless steel powder, S i 02 , Ti 03 or MgO in water, and depositing it on the base 2 for about 30 minutes.
It was coated to a thickness of about μ and cured at room temperature for 3 hours. The purpose of this reflective film 3j is to make the surface of the substrate stainless steel, and its spectral reflectance is 77% or more over the entire wavelength range.

Furthermore, an infrared ray generating resistor 4 is superposed on the infrared reflecting film 3. This single resistor is made of glass cloth impregnated with conductive carbon black or graphite, and epoxy or acrylic resin is used as the coupling agent. Further, electrodes 4a are formed at both ends of the infrared ray generating resistor 4, and are made of machine string or copper foil superposed on the infrared ray generating resistor 4.

As described above, since a ferromagnetic material is not used in the infrared ray generating resistor of the infrared ray emitting device based on the present invention,
It is not strongly magnetized by the magnetic field generated when current is supplied. This means that when a resistor containing a ferromagnetic material such as a nichrome wire is used, the magnetic field formed by the resistor may easily cause magnetic resonance in the irradiated material, which may have an adverse effect, and infrared rays may not be sufficiently effective. This is significant in that there are things that do not work.

Further, on the upper surface of the infrared ray generating resistor 4, there is provided a DJ that efficiently emits only light of a wavelength that is absorbed by the reaction molecules or atoms of the reactant.

Kamaishi is coated with a material selected from among inorganic materials, organic materials, or mixtures thereof, such as, for example, which enables efficient irradiation of Kamaishi with wavelengths in the infrared absorption spectrum region necessary for reaction of the irradiated object. Specifically, the spectral emissivity of these listed substances at various wavelengths is calculated, and the proportion of these emissive substances is determined based on the wavelength band and energy range required for the reaction of the irradiated object. You can choose the right spectral distribution of your desired infrared radiation.

Further, the outermost surface of the infrared radiating device 1 is coated with a laminate made of polyester, polyethylene, acetate, epoxy, nylon, polyamide, polyimide, polypropylene, or polystyrene, and is coated with a laminate made of polyester, polyethylene, acetate, epoxy, nylon, polyamide, polyimide, polypropylene, or polystyrene. This membrane absorbs the energy of
This creates a kind of filter effect. At the same time, the infrared radiation device 1 is provided with moisture resistance, water resistance, weather resistance, electrical insulation, and the like.

The electrode 4a of the infrared ray generating resistor 4 is connected to a controller 9 via a conductive wire 8. The controller 9 is further connected to a power source 10, and a signal from the warm melon 1 sensor 6a embedded in the overtop coat film 6 is supplied to the controller 9 through a line (not shown). The controller 1 to the roller 9 control the current supplied to the infrared ray generating resistor 4 based on the temperature detected by the temperature sensor 6a, and irradiate the irradiation target 7 with infrared rays having a desired wavelength distribution. The surface temperature of the radiation film 5 can be displayed. Further, a power regulator is also provided that can manually change the power supplied to the infrared ray generating resistor 4.

FIG. 2 shows another embodiment of an infrared radiation device according to the invention. Base 12 consists of the same monthly interest rate as the base 2 above.
is generally box-shaped, and its inner surface is coated with an infrared reflective film 13 similar to the infrared reflective film 3 described above. The inside of this box is divided into two parts by a partition wall 16 extending 4 inches from Y'31, which is the same material as the overtop coat Y6.

An infrared ray irradiation object 17 is placed in one of the two compartments, and an infrared ray generating device formed by coating an infrared ray emitting film 15 on an infrared ray generating resistor 14 similar to that described above is placed inside the other part. is provided.

Similarly to the above, a temperature sensor 16a is arranged adjacent to the partition wall 16 or the infrared emitting film 15, and supplies a detected temperature signal to the controller 19. The controller 19 is
Power is supplied from a power source 20, and the current supplied to the infrared ray generating resistor 14 via the conductive wire 18 is adjusted based on the detected temperature signal.

Further, as in the previous embodiment, a power regulator is also installed which allows the amount of electricity supplied to the infrared ray generating resistor 14 to be changed manually.

According to this embodiment, since the entire structure is sealed and the inner surface is coated with an infrared reflective film, the wooden wire that is not directly irradiated to the infrared irradiation object 17 is Since it is reflected by the film and reaches the object to be irradiated with infrared rays, most of the generated infrared rays are absorbed by the object to be irradiated with external rays, making it possible to irradiate infrared rays efficiently.

The infrared radiation device according to the invention can be configured in various shapes as described above. In particular, since it has a relatively flat configuration as shown in the first embodiment, by giving the base a concave mirror-like curvature, for example, infrared rays can be irradiated intensively to a narrow area. This is possible.
