Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device using a photocatalyst, and more particularly to a deodorizing device capable of efficiently decomposing and removing unpleasant odors generated from a garbage disposer, a kitchen or the like with a simple structure.

[0002]

2. Description of the Related Art Garbage generated from home kitchens, canteens, kitchens of restaurants and the like often emits offensive odor and deteriorates living environment. In addition, many odors that cause unpleasant sensation are included in the exhaust air from the air-conditioning equipment, and countermeasures are being studied. For example, kitchen waste processing machines have been put to practical use for the purpose of reducing the volume of kitchen waste, suppressing the spread of bad smells, and reusing kitchen waste. In such a garbage processing machine, garbage is decomposed into water and carbon dioxide gas by the action of microorganisms, but it is not completely decomposed, so gas containing chemical substances such as nitrogen compounds, sulfur compounds, and aldehydes is generated. Odors are generated. Therefore, a deodorizing means is provided in an exhaust port or an exhaust pipe of a kitchen waste disposal machine.

As the deodorizing means, it is common to use an adsorbent such as activated carbon, ozone or an oxidative decomposition catalyst. However, when the concentration of gas generated from garbage is high or a large amount of gas is generated, Since the deodorizing effect is reduced and the life of the deodorizing agent and the oxidation catalyst is short, there is a problem that replacement is required frequently (every 1 to 3 months).

[0004] In order to solve the above-mentioned problems, a deodorizing apparatus using a photocatalytic function (the oxidation-reduction power of an excited activated photocatalyst) has been proposed. This deodorizing device has a base on which a photocatalyst is arranged on the surface and an ultraviolet lamp as an excitation light source. When an odor generated from kitchen garbage is led to the substrate and brought into contact with a photocatalyst disposed on the surface, the odor, which is a kind of organic compound, is subjected to the oxidation-reduction effect of the photocatalyst excited and activated by an ultraviolet lamp, and finally to carbon dioxide Decomposes into gas and water.

A configuration in which a photocatalyst is applied to a deodorizing device of a kitchen waste disposal machine is disclosed in Japanese Patent Application Laid-Open No. Hei 9-313580. In this degassing device, the bad smell generated from the kitchen waste treatment machine is led through an exhaust duct to a deodorizing device composed of a porous body carrying a photocatalyst and an ultraviolet lamp, and is passed therethrough. As another example, Japanese Patent Application Laid-Open No. 9-314110 discloses that a garbage disposal chamber is connected to a first purification chamber having a spray chamber for purifying ammonia in a gas and spraying an aqueous solution on the gas,
A configuration is disclosed in which a second purification chamber for purifying sulfide in gas is connected to the purification chamber, and a photocatalyst layer and an ultraviolet lamp for irradiating the photocatalyst layer are provided between the two purification chambers.

[0006]

A conventional deodorizing device provided in an exhaust duct or the like has a low odor removing capability, and in order to improve the removing efficiency, it is necessary to use many parts with a complicated structure. Therefore, there is a problem that the cost of the apparatus is increased. In addition, there is a problem that an increase in the processing amount leads to an increase in the size of the apparatus. That is, in the conventional deodorizing device, since the ultraviolet lamp is installed in the center of the exhaust duct and the photocatalyst is arranged on the inner wall side, only the limited odor flowing near the inner wall side of the exhaust duct receives the oxidation-reduction effect,
The malodor flowing in the center of the exhaust duct did not sufficiently contact the photocatalyst, and most of the malodor was discharged outside without contacting the photocatalyst, and the removal efficiency could not be improved. Further, the deodorizing device provided with a photocatalyst layer and an ultraviolet lamp for irradiating the photocatalyst layer between the two purifying chambers can obtain a high purifying function, but has a problem that the device has a complicated structure and a large size. It is said that the oxidation-reduction decomposition of the photocatalyst causes a decomposition reaction when a substance to be treated comes into contact with an active radical species such as O ₂ ⁻ and OH ⁻ . Therefore, it is important to increase the time that the odor contacts the photocatalyst or increase the chance of contact. However, the above-mentioned conventional deodorizer has a configuration in which the photocatalyst and the gas to be treated do not sufficiently come into contact with each other, and there is a limit to the throughput.

Accordingly, an object of the present invention is to solve the problems of the prior art and to provide a small-sized deodorizing apparatus having high deodorizing efficiency.

[0008]

In order to achieve the above object, according to a first aspect of the present invention, there is provided a processing container having a built-in bubble generating means and containing water therein, and a first container connected to the processing container. , And a second photocatalyst unit installed in the processing container, wherein the first photocatalyst unit is a plurality of transmissive contact photocatalyst filters arranged radially and torsionally around the excitation light-emitting means.

In the first invention, it is preferable that a dehumidifying unit is disposed between the processing container and the photocatalytic unit. In order to achieve the above object, according to a second aspect, a processing container having a built-in bubble generating means and containing water therein,

In the present invention, the photocatalytic filter more preferably has a porous member including a plain woven wire mesh, a metal sintered layer supported on the surface thereof, and a photocatalytic functional layer supported on the surface. With this configuration, the chance of contact between the fluid to be treated and the photocatalytic filter increases. In the present invention, tap water and / or super-reduced water can be used as water in the treatment container.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. 1 is a schematic sectional view of a deodorizing apparatus according to one embodiment of the present invention, FIGS. 2 and 3 are schematic sectional views of a deodorizing apparatus according to another embodiment of the present invention, and FIG. 4 is a photocatalyst used in the present invention. FIG. 5 is a perspective view of the filter member, FIG. 5 is a side view of FIG.
FIG. 5 is a front view of FIG. 4. In FIG. 1, the deodorizing device 1 is
A processing container 4 which is connected to a container 2 containing garbage and has a bubble generating means 3 at its bottom and contains water, and a first photocatalytic unit 5 connected to this container 4 via a pipe 6
And a second photocatalyst unit 8 disposed in the processing container 4.
And an exhaust fan 9 connected to the first photocatalytic unit 5
Having. P is an air pump for sending air to the bubble generating means 3 under pressure. According to this deodorizing device, the air containing the odor generated from the container 2 is dissolved in the water in the processing container 4 and decomposed and removed by the second photocatalyst unit 8. On the other hand, the odor that is not dissolved in the water in the processing container 4 but remains on the upper portion is decomposed by the first photocatalyst unit 5 and then discharged out of the apparatus from the outlet (not shown) of the exhaust fan 9.

Since the deodorizing device 1 uses water in combination, dew condensation easily occurs inside the pipe 6 and the first photocatalyst unit 5, and if left as it is, a water film is formed on the surface of a photocatalyst filter described later to form a photocatalyst. Performance may be reduced. In order to prevent dew condensation, it is desirable to provide a dehumidifier 7 between the processing container 4 and the dehumidifier. By using the dehumidifier 7 (or instead of using the dehumidifier 7), the pipe 6 is shortened and installed so as to be inclined downward from the first photocatalyst unit 5 toward the processing vessel 4, so that the inside of the pipe 6 Water droplets may return to the processing container 4. Processing container 4
Tap water may be used as the water contained therein, but super-reduced water may be used alone or in combination with tap water in place of tap water to accelerate the generation of bubbles.

In the apparatus shown in FIG. 1, the gas-liquid contact efficiency can be further increased by increasing the processing container 4, but as shown in FIG. 2, the processing container 4 is divided and the air to be processed flows in series. Height can be suppressed. 2, the same parts as those in FIG. 1 are indicated by the same reference numerals.

FIG. 3 shows a first photocatalyst unit 5,
1 except that the air to be treated is treated in the order of the treatment container 4.
It is the same as the device of the above.

As shown in FIGS. 1 to 3, the first photocatalyst unit 5 has a case 50 and a photocatalyst filter member 51 housed therein. As shown in FIGS. 4 to 6, the photocatalyst filter member 51 includes a plurality of photocatalyst filters 13 that are radially and spirally twisted around a shaft member 10 formed in a frame shape, and the shaft member 1.
0, and an excitation light emitting tube 14 (not shown) inserted inside. The shaft member 10 is assembled by a plurality of gear-shaped retainers 11 and a plurality of stays 12, and the photocatalyst filter 1
Both ends and the center of 3 are supported by retainers 11.
The excitation light emitting tube 14 is formed in a U-shape, and is supported at one end by a socket portion 15. Excitation arc tube 1
4 is a wavelength 390 such as a black light or a fluorescent light.
Lamps that emit UV radiation below nm can be used. The case 50 reflects ultraviolet light emitted from the excitation light emitting tube 14 and guides the ultraviolet light to the photocatalytic filter 13. For example, when the ultraviolet light is near ultraviolet light, the case 50 has a function of reflecting an excitation wavelength such as an aluminum alloy or stainless steel. It is desirable to form with the material which has. Furthermore, if a photocatalytic function layer is formed on the inner surface of the case 50, the deodorizing efficiency will be higher. However, ultraviolet rays having a wavelength of 254 nm may be irradiated to obtain a sterilizing effect.

In the above-described photocatalytic unit, the positional relationship between the photocatalytic filter and the excitation luminous tube is important for sufficiently exhibiting the photocatalytic function. This will be described with reference to FIG. FIG. 7 corresponds to FIG. 5 (left side view of FIG. 4), in which one end of the photocatalytic filter 13 (only one is shown) is at a predetermined angle with respect to a straight line X passing through the central axis P of the retainer 11. It is held in the holding groove 16 of the retainer 11 at an inclination angle θ1 and at equal angular intervals (mounting angle) θ2. The other end of the photocatalyst filter 13 (the right side as viewed in FIG. 4) is also held in the holding groove 16 of the retainer 11 as in FIG.
As shown in FIG. 7, the photocatalyst filter 13 is twisted so as to intersect the central axis P by a predetermined angle (twist angle) θ3. The torsion angle θ3 is set to be, for example, an integral multiple (2 or more) of the mounting angle θ2.

The inclination angle θ 1 is preferably set in a range such that the ultraviolet light and its reflected light are irradiated on the entire surface of each photocatalytic filter 13.
Is 24, it is sufficient to make θ1 = 30 °. The larger the torsion angle θ3, the greater the chance of contact between the photocatalyst filter 13 and the fluid to be treated. However, if the torsion angle θ3 is too large, processing of the photocatalyst filter 13 becomes difficult.
In the case of sheets, it is sufficient to set θ3 = 45 ° {3 × θ2 (= 15 °)}. The photocatalytic filter 13 is preferably arranged symmetrically around the shaft member 10,
The number may be appropriately determined according to the type of the fluid to be processed, the flow velocity, and the like. However, in order to secure the inclination angle θ1 at a predetermined angle, the number is 24 or less (for example, 12 or 6).
Is preferred.

According to the photocatalyst unit 5, the air to be treated, which has flowed into the inside, comes into contact with the photocatalyst filter 13, is oxidized and decomposed by the photocatalyst activated by ultraviolet rays from the excitation light-emitting tube 14, and is deodorized. Air is exhausted outside the device. Since the photocatalyst filter 13 is arranged to be inclined with respect to the excitation light-emitting tube 14, the photocatalytic function layer can receive a large amount of ultraviolet light evenly, and the photocatalytic function can be reliably achieved. If the oxidative decomposition by the photocatalyst is continuously performed, in the case of a nitrogen compound, a sulfur compound or a chlorine compound, an intermediate product adheres to the surface of the photocatalytic functional layer, and the deodorizing efficiency is reduced. In that case, the photocatalyst filter 13 may be taken out of the photocatalyst unit 5 and attached to the photocatalyst unit 5 after cleaning.

As shown in FIGS. 1 to 3, the photocatalyst unit 8 has a case 80 and a photocatalyst filter member 81 housed therein. Photocatalyst filter member 81
As shown in FIG. 8, has a photocatalytic filter 17 spirally mounted around a cylindrical shaft member 16 and an excitation light emitting tube 14 inserted inside the shaft member 16. The excitation light emitting tube 14 is supported at both ends by a socket 15a and a socket 15b (FIGS. 1 and 3). As the excitation arc tube 14, a lamp such as a black light or a fluorescent lamp that emits ultraviolet light having a wavelength of 360 to 390 nm can be used. The case 80 reflects ultraviolet light emitted from the excitation light emitting tube 14 and guides the ultraviolet light to the photocatalyst filter 17. For example, when the ultraviolet light is near ultraviolet light, the case 80 has a function of reflecting an excitation wavelength such as an aluminum alloy or stainless steel. It is desirable to form with the material which has. Furthermore, if a photocatalytic function layer is formed on the inner surface of the case 80, the deodorizing efficiency will be higher.

According to the photocatalyst unit 8, the water contained in the processing container 4 comes into contact with the photocatalyst filter 17, and the air dissolved in the water by the photocatalyst activated by the ultraviolet light from the excitation light emitting tube 14 is removed. The water in the processing container 4 is purified while being oxidatively decomposed. Since the photocatalyst filter 17 is arranged obliquely with respect to the excitation light emitting tube 14, the photocatalytic function layer can receive a large amount of ultraviolet light evenly, and the photocatalytic function can be reliably performed.
If the oxidative decomposition by the photocatalyst is continuously performed, in the case of a nitrogen compound, a sulfur compound or a chlorine compound, an intermediate product adheres to the surface of the photocatalytic functional layer, and the deodorizing efficiency is reduced. In that case, the photocatalyst filter 17 may be removed from the photocatalyst unit 8 and attached to the photocatalyst unit 8 after cleaning.

In the present invention, the photocatalyst filters 13, 17
Is a substrate 2 having a large number of holes 21 as shown in FIG.
It is preferable that a porous layer 23 composed of fine particles 22 is formed on the substrate 0 and has a structure in which a photocatalytic functional film is increased on the surface of a substrate having a large surface area and having permeation contact performance. The fine particles may be made of any material such as ceramic, glass, metal, and plastic, but are preferably the same as the material of the substrate.
The substrate is preferably a net such as a wire net, expanded metal, or punched metal or the like.

In the present invention, a porous layer composed of fine particles is formed on the surface of a substrate as follows.
The contact with bad odor can be further improved. Average particle size 10-40
The slurry is obtained by applying a slurry (solid content: 60 to 80% by weight) in which a metal powder of 0 μm is mixed with a solvent such as water to the surface of the substrate, followed by drying and sintering. SUS304, SUS31 as a metal material for forming a substrate or fine powder
0, austenitic stainless steel such as SUS316,
Ti or its alloy (Ti-Mn system, Ti-Cr system, etc.), Cu or its alloy, Al or its alloy (Al-Si-Mg system), Fe or its alloy can be used. However, in the case of an Fe-based material, it is desirable to form an oxidation resistant film (iron oxide) on the surface. If the particle size of the metal powder is too small, the cost increases, and if the particle size is too large, fine pores cannot be obtained.
μm is preferred. The sintering temperature may be determined according to the material of the metal powder. However, if the sintering temperature is too low, a sufficient sintering density cannot be obtained, resulting in a decrease in strength. On the other hand, when the temperature is close to the melting point of the metal, the respective particles are fused to form coarse pores. Therefore, in the case of SUS, Ti, Cu, 800 to 1000
In the case of Al, a range of 300 to 400 ° C. is preferable.

The porous layer thus obtained is
It preferably has a pore diameter of 1000 μm. If the pore diameter is too large, fine foreign substances cannot be removed, while if it is too small, the resistance will increase and the processing capacity will decrease. Also,
The thickness of the porous layer is preferably in the range of 10 to 100 μm because the strength is reduced when the porous layer is thin and the transmission resistance is increased when the porous layer is thick.

In the present invention, the photocatalytic functional layer is made of, for example, T
A sol solution mixed with a photocatalytic semiconductor such as iO ₂ can be formed by spraying or dipping on the surface of a substrate, drying and baking at a temperature of 50 to less than 500 ° C. In addition to the photocatalytic semiconductor in this sol,
When amorphous titanium peroxide or titanium oxide is mixed in a titanium weight ratio (dry amount) of 1: 1 to 1: 5, the particles of the photocatalytic semiconductor can be firmly supported at a relatively low temperature. .

It is also possible to form a photocatalytic layer after spraying a protective material such as an aqueous solution of titanium peroxide on the surface of the substrate to form a protective coating. In any case, if a film is formed in advance with an aqueous solution of titanium peroxide, the adhesion and spreadability of the TiO ₂ sol solution are improved, so that the film is easily wetted, and the photocatalytic functional layer is uniformly and widely formed on the surface of the substrate. can do. This aqueous solution of titanium peroxide has excellent spreadability even when the substrate is made of a metal such as stainless steel, and is effective in applying the TiO ₂ sol solution widely and uniformly. Although the aqueous solution of titanium peroxide also functions as a binder, it does not include a ceramic-based one in terms of composition, and since it has good compatibility with metals, the photocatalytic functional layer formed on the surface of the base may be bent or vibrated even if the base is bent.
