Deodorizing apparatus by photocatalyst

[Detailed Description of the Invention]

Field of the Invention The present invention relates to the deodorization apparatus by the photocatalyst used for the measure against a bad smell of the bad smells (a cooking smell, a foodstuffs implement, a tobacco smell, body odor, a pet, the smell of a toilet, etc.) in a home or an office. PRIOR ART The ingredient of the bad smell (a cooking smell, a foodstuffs implement-tobacco smell, a pet, and a toilet it is stinking) which occurs in a home or an office, Nitrogen compounds (ammonia amine, Indore Skatole, etc.), Sulfuric compounds (hydrogen sulfide, methyl mercaptan, dimethyl sulfide, methyl disulfide, 2 dimethyl sulfide, etc.), Aldehyde (formaldehyde acetaldehyde etc.), ketone, alcohols (acetone etc.) (methanol ethanol etc.), fatty acid, aromatic compounds, etc. are various. Methods of deodorizing such a bad smell conventionally included the method of carrying out the chemical reaction of a bad smell substance and the medicine, the method of masking a bad smell substance with perfume, the method of adsorbing a bad smell substance by activated carbon, zeolite, etc., and the method of using combining these methods. Although various deodorization methods as mentioned above are used, after a medicine and perfume react to a bad smell substance, reproduction is almost impossible. If adsorption capacity is saturated also in adsorbent, deodorizing performance will fall remarkably. Therefore, it is [ with a new thing / exchange car ] periodically necessary for which case. Reduction or this operation itself is sharply required in the frequency of such troublesome operation (as a deodorization method, semiconductors, such as titanium oxide, are irradiated with ultraviolet rays, and use of the photocatalyst in which the semiconductor excited by it understands an organic matter etc. in an oxidized part is tried.). Object of the Invention In the deodorization method using a photocatalyst, acetaldehyde with difficult deodorization and other bad smell substances were effectively deodorized by the activated carbon generally used often, and maintenance of the performance was attained for a long period of time. However, with gas constituents, nicotine, other alkaloid phenol, hydrocarbon, etc. and dust are mixed, and the bad smell which occurs in a home and an office exists in the polymeric mass contained in the smoke of tobacco. Since they adhere to the semiconductor surface which is a catalyst which causes a photocatalytic reaction and cover this although these polymeric masses and dust have many which do not generate a bad smell, they cannot attain ultraviolet rays to a catalyst, but a catalyst is To (a photocatalytic reaction low-Conversion and causes reaction degradation.) to a receptacle about energy. The deodorization method using the conventional photocatalyst has such a solution subject. An object of the present invention is to obtain the deodorization apparatus by a photocatalyst which solves such a conventional subject, removes promptly the quality of high boiling point material and dust adhering to the semiconductor surface from which a photocatalytic reaction is started, and regains the original deodorizing performance again. Means for solving problem To achieve the above objects, the present invention serves as a photocatalyst layer which consists of semiconductors, and the ultraviolet-rays light and heating element which were countered and provided in it from a fan, and the whole photocatalyst layer is heated one by one, It is considered as the deodorization apparatus by the photocatalyst which a photocatalyst layer, a heating element or a photocatalyst layer, and a heating element move. OPERATION Although this artificer is considering the bad smell decomposition and no odor-ization by a photocatalytic reaction, The quality of high boiling point material (nicotine in the smoke of tobacco, other alkaloid phenol, hydrocarbon, etc.) and dust with coexisting [ more ] with a bad smell than before adhered on the catalyst surface, and it was afflicted by degradation of the photocatalytic reaction by an ultraviolet exposure being barred. It volatilizes by being heated at the high temperature of 380 degrees C~600 degreeC, and the quality of high boiling point material on such the adhering catalyst surface is decomposed, and it turns out by this that it is removed from the catalyst surface. It is decomposed similarly and the dust adhering to the catalyst surface is also removed. Reproduction temperature can lower to this semiconductor catalyst to 240degreeC by that catalyst activity by supporting platinum. Various the methods of actually applying have been examined about these catalyst active methods. what the method of removing a catalyst from a deodorization apparatus and heating with a heating device is complicated, and can be heated to near 400 degreeC at home -- preparing (being .) On the other hand, if it is going to heat the whole, equipping a deodorization apparatus with a catalyst, large electric power is required, and the rise in heat of ultraviolet-rays light and also the whole device is large, and durable-Victim and safety are problems. By the present invention's fixing a catalyst, and moving a heating element, or fixing a heating element, and moving a catalyst, the catalyst which deteriorated is heated to near 400 degreeC one by one, and, finally the whole is reproduced. Only the electric power with which a part of catalyst is heated by doing in this way may be used, and since unusual Temperature rising of ultraviolet-rays light or a deodorization apparatus is also stopped, it is safe and a problem does not have endurance, either. It bases and explains. in Drawing 1 and Drawing 2, l is a photocatalyst layer, and it fixes to the inside of cylindrical drum 5, and comes out of it. 2 is ultraviolet-rays light, there is at the center of drum 5 and it has countered photocatalyst layer 1. 3 is a heating element, and it counters photocatalyst layer 1, and it provides [ it approaches it and ] and comes out of it. Light reflector 4 is inside heating element 3, and heating efficiency is improved, and the rise in heat of ultraviolet-rays light 2 is prevented. In order to improve heating efficiency, thermal insulation 6 is wound around the outside of drum 5. Both 7.8 are the guides of drum 5, and they have turning blades 7a and 8a so that ultraviolet-rays light 2, heating element 3, and light reflector 4 may be supported in the meantime and air may flow along with photocatalyst layer 1. Drum 5 is supported by bearing 9 provided in guides 7.8. On the other hand, diameter gear 5a of a large is provided in the end of drum 5, it connects with drive motor 10 by byway gear 11, and drum 5 is rotated. With hoods 12a and 12b, 13 ventilates into drum 5 with a fan. It is a mount with which 14 fixes the support plate of a fan and 15 fixes the whole. Photocatalyst layer 1 makes this as follows, for example, although Anatase type titanium oxide is comprised here. After dipping Titania sol into the ceramic vapor of the quality of alumina silica of the thickness of 0 *51Tff11 molded into the cylindrical shape and impregnating it, it is considered as the photocatalyst layer which heat-treated by after-dryness 400 degrees C~700-degreeC, and supported titanium oxide. And this photocatalyst layer 1 is adhesives, such as water glass, and is stuck on the inside of drum 5. Since the portion which hits right above heating element 3 is not irradiated with ultraviolet rays, a catalyst is not established. As a catalyst, the mixed oxide of a rutile type titanium dioxide, platinum installation titanium oxide and titanium oxide, and tungstic oxide may be sufficient. The size of 300 g/nr and photocatalyst layer 3 of the amount of support of titanium oxide here is 250 m in inside diameter 1001IllI and length, and area is 785cnf. It may irradiate with the light which includes ultraviolet rays as ultraviolet-rays light 2, and what is necessary may just be that of nonglutinous rice, it may be considered as the ultraviolet rays with which it is irradiated, and a far ultraviolet ray or Near ultraviolet may be sufficient as The. As such an electric light, there are a low-pressure mercury lamp, a high-pressure mercury lamp, an ultrahigh pressure mercury lamp, etc., for example. These electric lights may be used alone and may be used together. Here, the germicidal light (ultraviolet-rays output 1.6W, dominant wavelength 253.7ruw) of 8W was used. Heating element 3 is I (it provided by lsi1 ml!L.) from photocatalyst layer 1 about Kolz infrared pipe 100v which can heat photocatalyst layer 1 more than 350 degreeC and in which Temperature rising should be just early here, 10 mm of 600W < outside diameters, and length 215 m. The Milacron heater and a sheath heater may be sufficient as this. Light reflector 4 uses a thing with aluminum or stainless sufficient reflectance. Ceramic wool yarn etc. are used as thermal insulation 6. Rotation of drum 5 by drive motor 10 rotates one time in about 15 minutes. The quantity of the wind sent by fan 13 is a part for about 0.5 ni(s)/. The usual operation is explained in the above-mentioned composition. First, when deodorizing, fan 13 and ultraviolet-rays light 2 are turned ON. Then, the air containing a bad smell flows along with photocatalyst layer 1, by being irradiated there with ultraviolet rays from ultraviolet-rays light 2, a bad smell ingredient is decomposed by hoods 12a and 12b and turning blades 7a and 8a, and non-bromination of it is carried out. However, a substance with a late photocatalytic reaction is also one of the substances in the atmosphere. This is adsorbed on the surface of photocatalyst layer 3, it comes to block ultraviolet rays gradually, and disassembly of 1. rigging substance also worsens. Then, the next operation is performed and photocatalyst layer 3 is reproduced. A device is put on the place of normal air and fan 13, heating element 3, and drive motor 10 are turned on. Then, photocatalyst layer 1 is heated at the same time Dorano and 5 begin to rotate slowly. By rotating one time, photocatalyst layer 1 is reproduced altogether. At this time, it is good to detect having rotated one time automatically and to turn off the switch with a microswitch etc. Next, the example of concrete reproduction is explained. First, the above-mentioned deodorization apparatus is put into the 1-d box made with aluminum. A box is sealed, and the saturated gas of acetaldehyde is poured in with an injector and it is made for concentration to be set to 8~9 ppm from a pouring mouth. After analyzing initial concentration, fan 13 and ultraviolet-rays light 2 of a deodorization apparatus are turned on. And the concentration of the acetaldehyde in a box is analyzed at intervals of 10 minutes. Analysis is Gas chromatograph analysis and used the FID detector. Thus, the measured early acetaldehyde decomposition curve is shown in Drawing 3 I. Next, six tobacco (Seven Stars) is automatically burned in a box, operating fan 13 of a deodorization apparatus. It is neglected in this state for 45 minutes, and the smoke of tobacco and a bad smell are made to stick to the surface of photocatalyst layer 1. The decomposition curve of acetaldehyde is measured in the same procedure as measurement of an early decomposition curve after this operation. This result is shown in Drawing 3 H. The result of ■ of this Drawing 3 shows that decomposition capability has almost disappeared at photocatalyst layer 1. Then, the next reproduction operation is performed. A deodorization apparatus is put on the place of a normal atmosphere, fan 13, heating element 3, and drive motor 10 are turned on, and it operates for about 15 minutes. Then, photocatalyst layer 1 rotates one time and the whole is heated to near 400 degreeC. The example of the Temperature rising curve of photocatalyst layer 1 at this time is shown in Drawing 4. This is a Temperature rising curve at the time of reproduction of the point of 20+nm (C) from 20 mm (a), a center (b), and an exit from the entrance of the side opposite to heating element 3 to ultraviolet-rays light 2. After this Temperature rising operation, when a deodorization apparatus cools, normal temperature is reached and the decomposition curve of °r Cedaraldehyde is measured again, it comes to be shown in 3rd [ The ] figure ■. Thus, the deodorization apparatus of this example is revitalized to 96% of performance, also after carrying out cruel degradation. EFFECT OF THE INVENTION As mentioned above, the deodorization apparatus of the present invention heats the photocatalyst polluted by the quality of high boiling point material which floats in the atmosphere, and dust to near 400 degreeC one by one by easy operation, and, finally the whole is reproduced. According to the present invention, the deodorizing performance can be maintained over a long period of time, without degrading the deodorizing performance by a photocatalyst in general living conditions called the inside of a home or an office. Only the electric power with which a part of catalyst is heated may be used, and since unusual Temperature rising of ultraviolet-rays light or a deodorization apparatus is also stopped, what is safe and was excellent also in endurance can be obtained.
