Description

  The present invention relates to a deodorizer using a photocatalyst, for example, and more particularly to a deodorizer suitable for removing pollutants without being affected by a temperature and humidity environment in an indoor space or a vehicle interior space.

A deodorizing technique using a photocatalyst has been reported. Examples of the photocatalyst include semiconductor metal oxides such as titanium dioxide, tungsten oxide, and zinc oxide. By irradiating them with ultraviolet rays, electrons in the valence band are excited and transition to the conduction band, and electrons and holes are generated. These move to the surface of the photocatalyst and react with pollutants in the air, or react with oxygen and water in the air to generate superoxide ions (O ^2- ) and hydroxy radicals (.OH). These are deodorized by reacting with pollutants. However, it is known that the deodorization by the photocatalyst is greatly affected by the humidity of the treated air, and there is a problem that the deodorization performance is deteriorated particularly in a high humidity region. On the other hand, it is conceivable to increase the deodorization efficiency of the photocatalyst by lowering the humidity of the processing air before performing the deodorization treatment with the photocatalyst. For example, deodorization methods such as Patent Document 1 and Patent Document 2 have been proposed. Yes.

That is, in the conventional example shown in Patent Document 1, the relative humidity of the contaminated air is reduced to 15% or less by heat-treating the contaminated air before the deodorization treatment with the photocatalyst with the heating unit, and then deodorized with the photocatalyst. It is to perform processing. In the conventional example shown in Patent Document 2, the relative humidity before the dehumidifying treatment of the contaminated air is 60% or more, the relative humidity before the air purification by the photocatalyst is 45% or less, or The relationship between the absolute humidity A before dehumidification and the absolute humidity B before air cleaning by the photocatalyst satisfies A / B ≧ 1.5.

  In the conventional example shown in the above-mentioned Patent Document 1, only a heating means is provided, and no countermeasure is taken against air treatment after deodorization. In other words, the air to be treated that has reached a high temperature in the heating section will be discharged as it is. For example, deodorizing equipment installed outdoors, etc., or even indoors, high-temperature air will be discharged outdoors using an exhaust duct. However, there is a problem that it cannot be used in a living space or a vehicle interior space because the indoor temperature rises excessively in a closed space. In addition, reducing the relative humidity to 15% or less with only heating means is not a problem in a relatively low humidity range, but is difficult in a high humidity range such as in rainy weather, and the performance of the photocatalyst is sufficient. There was a problem that it could not be demonstrated. Moreover, even if the humidity can be reduced, excessive heat energy is required, and there is a problem in cost.

  Further, it is generally known that the human nose tends to feel unpleasant odor particularly under high humidity conditions. In other words, in the above conventional example, only the relative humidity is temporarily lowered by the heating section, and the relative humidity of the cooled air to be treated rises again, resulting in high humidity in the room air. There was a problem that it was not possible to provide a comfortable indoor environment.

  Moreover, in the conventional example shown by patent document 2, although the process by chemical | medical agents, such as a desiccant and a dehumidifier, and the process by apparatuses, such as a dehumidifier, are performed as a dehumidification means, a desiccant, a dehumidifier, etc. The dehumidifying means using the chemicals has a problem that a large amount of cost and human labor are required for maintenance. In addition, since dehumidifying means using a dehumidifier requires a large amount of cost such as cooling equipment and a compressor, it has not been practical to incorporate these as equipment only for dehumidification. Moreover, in the above conventional example, it is said that the humidification is appropriately performed when the humidity change before and after the treatment is not desired. However, the means is not specified, and a countermeasure for overdrying in a low humidity environment is not provided. It was insufficient.

  The present invention has been made in view of such a conventional problem, and solves the conventional problem by utilizing a dehumidification mechanism using a dehumidification rotor and a regeneration mechanism thereof used in home dehumidifiers. Thus, the deodorizing ability of the photocatalyst can be remarkably improved. That is, the present invention is relatively low cost, easy to maintain, and can prevent an excessive increase in room temperature even in a closed indoor space such as a house or a car. In addition, the present invention provides a deodorizing machine that can provide a comfortable indoor environment by satisfying excellent deodorizing performance against various bad odors and keeping the room at an appropriate humidity without reducing the deodorizing performance even in a high humidity environment. For the purpose.

  In order to achieve the above object, a deodorizer according to the present invention includes a circular deodorization rotor carrying a photocatalyst and an adsorbent, an excitation unit that irradiates a part of the deodorization rotor, and A dehumidification rotor disposed upstream of the deodorization rotor, provided with a rotation mechanism, a regeneration unit that heats and regenerates a part of the dehumidification rotor with a heater, and heat exchange disposed between the deodorization filter and the dehumidification rotor , A regeneration air passage that circulates through the regenerator and the heat exchanger, and agglomerates water, a water storage tank that is disposed below the heat exchanger and stores the agglomerated water, and a blower that is disposed downstream of the deodorizing rotor And a processing air passage that takes in the air to be treated indoors by the blower and returns the air deodorized by the deodorizing rotor after passing through the dehumidifying rotor, and heats the air to be treated dehumidified by the dehumidifying rotor with a heat exchanger By It is characterized in that the relative humidity of the process air is always a low humidity condition.

  The deodorizer according to claim 6 includes a temperature / humidity sensor and a water channel for dropping water dehumidified by the heat exchanger onto the deodorization rotor, and the relative humidity in the regeneration air channel is high. In some cases, water condensed in the heat exchanger is stored in a water storage tank, and when the humidity is low, the water channel is controlled so that the deodorizing rotor drops through the water channel.

  The deodorizer according to claim 14 is characterized in that a deodorizer is added to the dehumidifying rotor.

  Further, the deodorizer according to claim 15 is characterized in that a catalyst is added to the dehumidifying rotor.

  According to the present invention, the air to be treated, which has been dehumidified in advance by the dehumidifying rotor, is heated using a heat exchanger, so that the relative humidity of the air to be treated is always kept low with less heat energy even in a high humidity atmosphere. It is possible to maximize the deodorizing performance of the photocatalyst while suppressing excessive temperature rise in the room. In addition, when the room is at high humidity, the dehumidified water is stored in a tank, and when the room is at low humidity, the dehumidified water is vaporized again by using a deodorizing rotor to suppress overdrying. Therefore, it is possible to provide a deodorizer that can maintain a comfortable humidity in the room without any problems and provide a comfortable and clean indoor environment.

  In order to achieve the above object, a deodorizer according to claim 1 of the present invention includes a circular deodorization rotor that carries a photocatalyst and an adsorbent, an excitation unit that irradiates a part of the deodorization rotor, and the deodorization device. A dehumidification rotor disposed upstream of the rotor and provided with a rotation mechanism, a regeneration unit for regenerating by heating a part of the dehumidification rotor with a heater, and a heat exchanger disposed between the deodorizing filter and the dehumidification rotor A regenerator that circulates through the regenerator and the heat exchanger and aggregates the water, a water storage tank that is disposed below the heat exchanger and stores the condensed water, and a blower that is disposed downstream of the deodorizing rotor The air to be treated is taken in by the blower, and after passing through the dehumidifying rotor, the air deodorized by the deodorizing rotor is returned to the room, and the air to be treated dehumidified by the dehumidifying rotor is heated by a heat exchanger. , Processed It is characterized in that the relative humidity of the air at all times of low humidity conditions.

  First, the deodorizing rotor will be described. The deodorizing rotor according to the present invention is obtained by carrying a mixture of a photocatalyst and an adsorbent at an arbitrary blending ratio on a substrate surface together with an adhesive component.

  Various photocatalysts can be mentioned, but titanium oxide is most suitable from the viewpoint of structural stability, safety, and ability to decompose and remove harmful substances, and is also effective as a photocatalyst according to the present invention.

  Examples of the adsorbent include porous materials having meso-micropores such as activated carbon, zeolite, silica gel, and sepiolite. Titanium oxide itself has almost no property of adsorbing malodorous substances. In order to decompose malodorous substances with a photocatalyst, it is necessary to once capture the malodorous substances with an adsorbent. When both the titanium oxide and the adsorbent are supported on the base material, the method of mixing both in advance and then supporting the base material on the base material is the simplest, and evenly considering the contact efficiency of malodorous substances to the titanium oxide It is desirable to mix them, but if an adsorbent having an absorption edge in the ultraviolet wavelength region of 400 nm or less where titanium oxide is excited at this time is mixed, the adsorbent absorbs ultraviolet rays, and the excitation efficiency of titanium oxide is remarkably high. There is a risk of decline. Zeolite and silica gel are suitable as adsorbents that do not have an absorption edge in the ultraviolet wavelength region of 400 nm or less. Particularly, high silica zeolite obtained by hydrophobizing zeolite has almost no absorption wavelength near 400 nm and is hydrophobized. This is advantageous as an adsorbent mixed with a photocatalyst in order to improve the ability to adsorb malodorous substances.

  Examples of the substrate supporting the photocatalyst and the adsorbent include various materials such as ceramic honeycomb, foamed ceramic, foamed urethane, glass, glass fiber cloth, aluminum honeycomb, non-woven fabric, and papermaking honeycomb, but have UV resistance. It is desirable that In addition, it is desirable that the material is capable of ensuring photocatalytic performance and supporting strength, and the ceramic honeycomb and the foamed ceramic are porous, so that the supporting strength is easy to secure, and malodorous substances are adsorbed to the base material itself. Suitable for base materials because it can be expected. In addition, a glass fiber cloth called a living machine that bundles a number of glass fibers to form a single thread is easy to ensure carrying strength because one thread has a three-dimensional structure, and Since the material is glass, it is excellent in UV transparency, which is also suitable for a substrate.

  As an excitation part for exciting the photocatalyst, for example, a UV lamp such as a cathode ray tube, a black light, a germicidal lamp, or an LED is suitable, but there is no difference in the effect even if any means is used as long as the photocatalyst can be excited. .

  Next, the dehumidifying mechanism will be described. The dehumidifying mechanism according to the first aspect of the present invention includes a dehumidifying rotor disposed upstream of the deodorizing rotor and provided with a rotating mechanism, a regenerating unit that heats and regenerates a part of the dehumidifying rotor with a heater, A heat exchanger disposed between the deodorizing filter and the dehumidification rotor, a regeneration air passage for aggregating water by circulating through the regeneration unit and the heat exchanger, and a condensed air disposed at a lower portion of the heat exchanger It consists of a water storage tank.

  The dehumidification rotor is formed by corrugating a base paper mixed with glass fibers to form a base material, forming a base material, carrying a hygroscopic material (zeolite) on this, firing, and slice-cutting. . Zeolite used as a hygroscopic material is close in water adsorption energy and vaporization energy, and therefore has excellent absorption and desorption properties, and can repeat dehumidification and regeneration. The dehumidification rotor has a rotation mechanism, and rotates at a constant speed in conjunction with rotation of a separately provided motor. A heater is disposed in the regeneration unit so as to be close to the dehumidification rotor at an angle within a certain range. When the dehumidification rotor rotates, moisture absorbed in the portion heated by the heater is released and regenerated.

  A heat exchanger flows air having different temperatures through two different air passages and exchanges only heat energy, thereby heating low-temperature air and cooling high-temperature air. At this time, if the air on the high temperature side is highly humid, the saturated vapor pressure is lowered by cooling, and moisture is condensed on the wall surface of the air passage by dropping below the dew point, so that the absolute humidity in the air can be lowered. By disposing the heat exchanger between the deodorizing rotor and the dehumidifying rotor, first, when the air to be treated, which has become low in humidity by passing through the dehumidifying rotor, passes through the heat exchanger, the high temperature flowing through another air passage It is heated by being heat exchanged with the air, becomes low humidity and high temperature, and has an effect that it can be efficiently decomposed by the photocatalyst. Further, the regenerator and the heat exchanger form a circulation air path by a separately provided air blowing means. High-humidity air containing moisture released from the dehumidifying rotor is cooled by a heat exchanger in order to condense, and accumulates in a water storage tank disposed at the lower part of the heat exchanger. By doing so, deodorizing can be performed while dehumidifying even in a high humidity atmosphere such as rainy weather, and comfortable clean air can be provided. The diameter of the deodorizing rotor may be any size as long as a certain degree of deodorizing capability can be secured, but by making the dehumidifying rotor and the deodorizing rotor the same diameter, the air path can be made uniform and compact.

  The deodorizer according to claim 2 is characterized in that the deodorization rotor rotates in conjunction with the rotation of the dehumidification rotor. In order to effectively use all the supported photocatalyst, for example, when an ultraviolet lamp is used as an excitation part, it is important to uniformly irradiate the photocatalyst with ultraviolet rays. However, in order to irradiate the entire surface of the deodorizing rotor with light, a large number of ultraviolet lamps must be arranged, and an appropriate arrangement must be considered in order to make the irradiation intensity uniform. By doing so, it is not necessary to arrange the excitation part on the entire surface of the deodorizing rotor, and the cost can be reduced. Further, by rotating about the center of the rotor, the irradiation intensity can be made uniform, and the deodorizing ability by the photocatalyst can be efficiently exhibited. Note that the rotation speeds of the dehumidification rotor and the deodorization rotor need not be uniform, and the rotation speed may be controlled by changing the gear ratio of the rotation mechanism that transmits the rotation of the dehumidification rotor to the deodorization rotor. Further, a mechanism for controlling the rotational speed in accordance with the indoor odor intensity may be provided by providing a separate odor sensor.

  Further, the deodorizer according to claim 3 is characterized in that a part of the rotating deodorizing rotor is heated by a heater of the regeneration unit. The heater disposed in the vicinity of the dehumidifying rotor is sandwiched between the dehumidifying rotor and the deodorizing rotor, and the heat of the heater can be transmitted to the deodorizing rotor by narrowing the interval between the dehumidifying rotor and the deodorizing rotor. By doing so, a part of the deodorizing rotor is heated by the heater while rotating, so that the surface of the deodorizing rotor can always be kept at a high temperature. By doing this, the relative humidity is lowered when the air to be treated passes through the deodorizing filter, and the photocatalyst can efficiently decompose.

  Further, the deodorizer according to claim 4 is characterized in that the water condensed by the heat exchanger is dropped on the heated deodorization rotor to be vaporized and discharged into the room. By doing so, it is possible to suppress the dehumidification of the indoor space excessively and to supply comfortable clean air to the room by lowering the waste heat temperature by the heat of vaporization.

  Further, the deodorizer according to claim 5 is characterized in that the place where water is dropped on the deodorization rotor is a front portion of the heater. In this way, the rotating deodorizing filter has an effect that it is possible to release all moisture before reaching the treatment air passage for deodorizing the air to be treated, and to suppress the deodorization performance from being lowered.

  The deodorizer according to claim 6 includes a temperature / humidity sensor and a water channel for dropping water dehumidified by the heat exchanger onto the deodorization rotor, and the relative humidity in the regeneration air channel is high. In some cases, water condensed in the heat exchanger is stored in a water storage tank, and when the humidity is low, the water channel is controlled so that the deodorizing rotor drops through the water channel.

  The water channel is provided to be branched from a portion that leads from the heat exchanger to the water storage tank, and the tip of the water channel is disposed so that the rotating deodorizing rotor is dropped on a portion in front of the portion heated by the heater. . By doing so, the dripped water is all released before the deodorizing rotor performs the deodorizing process, and the deodorizing performance can be prevented from being lowered. In addition, the inlet of the branched water channel is controlled to open and close automatically depending on the value of the temperature and humidity sensor. When the room is in high humidity, dehumidified water is stored in the tank. By re-evaporating water, excessive drying is suppressed, humidity is adjusted according to the indoor temperature and humidity environment, and a comfortable indoor space can be maintained. The temperature / humidity that becomes the boundary between high humidity and low humidity in the control is, for example, 50% to 60% at 25 ° C.

  Further, the deodorizer according to claim 7 is characterized in that the processing air passage and the portion to be heated by the dehumidification rotor and the heater of the deodorization rotor are partitioned. A part of the dehumidification rotor and deodorization rotor is arranged facing the processing air passage, and in order to ensure the dehumidifying capacity and deodorizing ability, about half the area of the rotor surface faces the processing air passage. Preferably they are arranged. On the other hand, a part rotating outside the processing air path is a part heated by a heater, and the rest is used as a natural cooling part or a water dropping part. At this time, the portion rotating outside the processing air passage is partitioned with the processing air passage and the wall surface, and high-humidity air generated when the dehumidification rotor and the deodorizing rotor are overheated by the heater is placed in the processing air passage. Has the effect of suppressing the inflow. By carrying out like this, it has the effect | action that it maintains the humidity of the to-be-processed air which passes a deodorizing rotor at low humidity, and can decompose | disassemble efficiently with a photocatalyst.

  The deodorizing machine according to claim 8 is characterized in that the deodorizing rotor is disposed below the dehumidifying rotor such that the projection surface partially overlaps the dehumidifying rotor. By doing so, the water channel that guides the water condensed in the heat exchanger to the deodorizing rotor can be directed downward, and the condensed water can be introduced into the deodorizing rotor without using a separate conveying means. Moreover, by setting it as such a step structure, a water storage tank can be accommodated in the space created under the dehumidification rotor and the heat exchanger, and the body can be made compact. The degree of disposing the deodorizing rotor below the dehumidifying rotor is not limited as long as the heater can be accommodated on the projection surface. However, considering the air path configuration and the simplicity of the rotating mechanism, It is preferable to arrange it below the radius.

  The deodorizer according to claim 9 is characterized in that the water accumulated in the water storage tank is sterilized at the excitation part. By doing so, the water storage tank can be kept clean, and the operation can be simplified. In addition, although the excitation part which sterilizes a water storage tank may be provided separately from what excites a photocatalyst, the excitation part of a water storage tank and a photocatalyst is arrange | positioned by shifting a deodorizing rotor downward as described in Claim 8. And the storage tank can be sterilized simultaneously with the excitation of the photocatalyst.

  The deodorizer according to claim 10 is characterized in that the excitation part is a germicidal lamp. By doing so, it not only excites the photocatalyst, but also has an effect that water accumulated in the water storage tank can be sterilized efficiently.

  The deodorizing machine according to claim 11 is characterized in that the base material of the deodorizing rotor is a glass fiber cloth. Glass fiber cloth is made by bundling a number of glass fibers into a single thread and weaving it to form a single cloth. This is cut into a circular shape and carries a photocatalyst and a deodorant. Form a deodorizing rotor.

  The glass fiber cloth has a three-dimensional structure of one yarn, so that it is easy to ensure the supporting strength, and since the material is glass, it has excellent UV resistance and heat resistance. By doing so, the surface of the deodorizing rotor can always be kept at a high temperature, and when the air to be treated passes through the deodorizing filter, it has a lower humidity and a higher temperature and can be efficiently decomposed by the photocatalyst.

  The deodorizing machine according to claim 12 is characterized in that the base material of the deodorizing rotor is a ceramic honeycomb. The circular ceramic honeycomb substrate can be formed by a manufacturing method almost the same as that of the dehumidifying rotor, but it can have deodorizing performance by carrying a deodorizing agent instead of the moisture absorbent and then firing. In addition, you may carry | support the thing which mixed the photocatalyst simultaneously with carrying | supporting a deodorizing agent, but when a structural change of the photocatalyst by a heat | fever is concerned in a baking process, you may carry a photocatalyst again after baking.

  At this time, only the photocatalyst may be supported, but it is more preferable to support a mixture of the photocatalyst and the deodorant. Ceramic honeycombs are excellent in UV resistance and heat resistance. By doing so, the surface of the deodorizing filter can always be kept at a high temperature, and the air to be treated becomes higher in temperature and humidity when passing through the deodorizing filter, so that it can be efficiently decomposed by the photocatalyst. In addition, the honeycomb shape increases the contact area with the air to be treated, thereby improving the deodorizing effect.

  The deodorizer according to claim 13 is characterized in that a noble metal catalyst is added to the deodorization rotor. Examples of the noble metal catalyst include Pt and Pd. Although these catalysts can exhibit a deodorizing effect even at room temperature, they can exhibit a higher catalytic activity when heated by a heater part, and can obtain an excellent deodorizing effect. By carrying out like this, in addition to the deodorizing by a photocatalyst, the high deodorizing capability can be obtained also in the part heated with a heater, and a deodorizing machine with higher deodorizing performance can be provided.

  The deodorizer according to claim 14 is characterized in that a deodorizer is added to the dehumidifying rotor. The deodorant can be added with an adsorbent that physically adsorbs malodorous substances such as activated carbon, zeolite, silica gel, and sepiolite, and a chemical adsorbent that deodorizes by chemically reacting with the malodorous substance, or both. May be added. By carrying out like this, it can deodorize simultaneously with to-be-processed air dehumidifying when passing a dehumidification rotor, and can provide a deodorizing machine with higher deodorizing performance.

  Further, the deodorizer according to claim 15 is characterized in that a catalyst is added to the dehumidifying rotor. As the catalyst, a noble metal catalyst such as Pt or Pd, or a metal oxide such as MnO 2 or ZnO can be added. Although these catalysts can exhibit a deodorizing effect even at room temperature, they can exhibit a higher catalytic activity when heated by a heater part, and can obtain an excellent deodorizing effect. By carrying out like this, it can deodorize simultaneously with to-be-processed air dehumidifying when passing a dehumidification rotor, and can provide a deodorizing machine with higher deodorizing performance.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

(Embodiment 1)
A deodorizer according to the present invention is shown in FIG. As shown in FIG. 1, a deodorizer 1 includes a deodorization rotor 2 in which a photocatalyst and an adsorbent are supported on a ceramic honeycomb substrate, a cold cathode tube 3 for exciting the photocatalyst, and a rotary motor upstream of the deodorization rotor 2. 4, a dehumidification rotor 5, a rotation mechanism 6 that transmits rotation to the deodorization rotor 2, a regeneration unit 8 that includes a heater 7 that heats and regenerates part of the dehumidification rotor 5 and the deodorization rotor 2, and a deodorization rotor 2 and a heat exchanger 9 disposed between the dehumidifying rotor 5, a regenerator 8 and a regenerative air passage 10 that circulates the heat exchanger, a temperature / humidity sensor 11 provided at the suction port, and a lower part of the heat exchanger The water storage tank 12 for storing the condensed water, the water channel 13 for introducing the condensed water to the water storage tank 12 or the deodorizing rotor 2, the blower 14 disposed downstream of the deodorizing rotor, and the indoor cover by the blower 14. Process air 15 And a processing air passage 16 for returning the air deodorized by the deodorizing rotor 2 to the room after passing through the dehumidifying rotor 5, dehumidifying the air to be treated 15 introduced from the suction port 17 and then deodorizing with the deodorizing rotor 2, It is a mechanism for supplying clean air from the outlet 18. As the water channel 13, it is sufficient if water can be passed, and for example, there is a water pipe.

  The deodorizing rotor 2 is formed by mixing a fine powder photocatalyst and an adsorbent in an arbitrary blending ratio to form a slurry by adhering it to the ceramic honeycomb substrate surface and drying it. Titanium oxide is used for the photocatalyst, and high silica zeolite is used for the deodorizer. Ceramic honeycombs are excellent in UV resistance and heat resistance. By doing so, the surface of the deodorizing rotor can always be kept at a high temperature, and when the air to be treated 15 passes through the deodorizing rotor, it becomes hot and low in humidity, so that it can be efficiently decomposed by the photocatalyst. In addition, the honeycomb shape increases the contact area with the air to be treated 15 and improves the deodorizing effect. In the present embodiment, a ceramic honeycomb is used as the base material of the deodorizing rotor 2, but a plurality of glass fiber cloths formed in a circular shape may be used, and a glass fiber cloth having no thickness may be used. Then, it has the effect | action that irradiation efficiency can be raised by inserting | pinching the cold cathode tube 3 with a cloth | cross.

  The dehumidifying rotor 5 is formed by corrugating a base paper mixed with glass fiber to form a base material, forming a base material, carrying a hygroscopic material (zeolite) on this, firing, and slice-cutting It is. Further, the dehumidifying rotor 5 is rotated at a constant speed by a rotary motor 4 connected to the central portion, and returns to the adsorbing portion again through the adsorbing portion, the regenerating portion, and the cooling portion during one rotation. Yes. The adsorption part occupies half of the circular part of the dehumidification rotor, and dehumidifies the air to be treated by passing through the adsorption part. Next, the regenerating unit 8 is heated by the heater, and the water adsorbed by the adsorbing unit is released and regenerated. Finally, the cooling unit is naturally cooled by the outside air and can be adsorbed again. By doing so, the dehumidification rotor 5 repeats the absorption and discharge while rotating, and can continuously dehumidify the air to be treated 15.

  The rotation motor 4 is connected to the rotation mechanism 6 via a rotation shaft, and the deodorization rotor 2 rotates in conjunction with the rotation of the dehumidification rotor 5. Further, a plurality of cold cathode tubes 3 are arranged so as to irradiate the portion facing the processing air passage 16 of the deodorizing rotor 2 from both sides, and the photocatalyst can be excited efficiently. In order to effectively use all the supported photocatalyst, it is important to uniformly irradiate the photocatalyst with ultraviolet rays. Therefore, it is necessary to arrange a large number of cold cathode tubes 3 on the entire surface of the deodorizing rotor 2, and in addition, an appropriate arrangement must be considered in order to make the irradiation intensity uniform. Therefore, by rotating the deodorizing rotor 2, the entire surface of the deodorizing rotor 2 can be irradiated with light simply by disposing the cold cathode tube 3 on a part of the deodorizing rotor 2. Further, by rotating about the center of the rotor, the irradiation intensity can be made uniform, and the deodorizing ability by the photocatalyst can be efficiently exhibited. Any means can be used as the excitation unit as long as it can excite a photocatalyst such as a UV lamp such as a black light, a germicidal lamp, or an LED, or plasma excitation, but the cold cathode tube is relatively low cost and durable. Since it has a long lifetime, it is preferable as an excitation part. The number and the arrangement of the cold cathode tubes 3 may be any as long as a certain deodorizing performance can be ensured, but by arranging them radially at equal intervals from the center of the circle as in this embodiment. , It has the effect that the irradiation area can be made uniform.

  Further, as the rotation mechanism 6 of the deodorizing rotor 2, a method in which the rotation shaft is directly connected to the central portion of the deodorization rotor 2 and the rotation of the rotation motor 4 is directly transmitted to the deodorization rotor 2 is simple. In this case, the rotational speed of the dehumidifying rotor 5 and the deodorizing rotor 2 can be changed by providing a plurality of gears having different rotation ratios. You may provide the mechanism which controls a rotational speed according to indoor odor intensity | strength by providing an odor sensor separately.

  The deodorizing rotor 2 and the dehumidifying rotor 5 are arranged so as to sandwich the heater 7 therebetween. The heater 7 heats and regenerates the dehumidifying rotor 5 by the regenerating unit 8 of the dehumidifying rotor 5, and at the same time, It is a mechanism to heat the part. That is, since the deodorizing rotor 2 rotates while part of the rotor is heated by the heater 7, the rotor surface can always be kept at a high temperature. By carrying out like this, when the to-be-processed air 15 passes the deodorizing rotor 2, relative humidity becomes low, and it has the effect | action that it can decompose | disassemble efficiently with a photocatalyst.

  The heat exchanger 9 is disposed between the dehumidifying rotor 5 and the deodorizing rotor 2, and air having different temperatures is supplied to the two air passages, and only heat energy is exchanged to heat low-temperature air. The air is cooled. At this time, if the air on the high temperature side is highly humid, the saturated vapor pressure is reduced by cooling, and moisture is condensed on the wall surface of the air passage by lowering the dew point, thereby reducing the absolute humidity in the air. In other words, the air to be treated 15 dehumidified by the dehumidifying rotor 5 and the regeneration air heated by the heater 7 intersect each other in the heat exchanger 9 separated by the wall surface, whereby the air to be treated 15 is heated and regenerated. The air is cooled and dehumidified by moisture condensing on the wall surface of the heat exchanger 9.

Is controlled. The water channel 13 to be introduced into the deodorizing rotor 2 is branched from a portion that leads from the heat exchanger 9 to the water storage tank 12, and the tip thereof is before the portion where the rotating deodorizing rotor 2 is heated by the heater 7. It is arrange | positioned so that it may be dripped at the part of. By doing so, the dripped water is released before the deodorizing rotor 2 performs the deodorizing process, and it is possible to suppress the deodorizing performance from being deteriorated.

  In other words, when the room is highly humid, dehumidified water is stored in the tank, and when the room is low humidity, the dehumidified water is vaporized again to suppress excessive drying and adjust the humidity according to the indoor humidity environment. It has the effect of maintaining a comfortable indoor space. In addition, as a conveyance means for introducing the water in the water channel 13 into the deodorizing rotor 2, a liquid feed pump or the like may be provided separately, and a water absorption material is filled in the water channel, thereby conveying the water by a capillary phenomenon. May be used. Moreover, the deodorizer 1 in this Embodiment may carry | support a catalyst on the dehumidification rotor 5, and a noble metal catalyst, such as Pt and Pd, and metal oxides, such as MnO2 and ZnO, can be added to a catalyst. These catalysts can exhibit a deodorizing effect even at room temperature, but when heated by the heater 7, a higher catalytic activity can be exhibited and an excellent deodorizing effect can be obtained. By carrying out like this, when the to-be-processed air 15 passes through the dehumidification rotor 5, it can deodorize simultaneously and can provide a deodorizer with higher deodorizing performance.

  The deodorizing rotor 2 is formed by mixing a fine powder photocatalyst and an adsorbent in an arbitrary blending ratio to form a slurry by adhering it to the ceramic honeycomb substrate surface and drying it. Titanium oxide is used for the photocatalyst, and high silica zeolite is used for the deodorizer. Ceramic honeycombs are excellent in UV resistance and heat resistance. By doing so, the surface of the deodorizing rotor can always be kept at a high temperature, and the air to be treated 15 has a higher temperature and lower humidity when passing through the deodorizing rotor 2 and can be efficiently decomposed by the photocatalyst.

In the present embodiment, a ceramic honeycomb is used as the base material of the deodorizing rotor 2, but a plurality of glass fiber cloths formed in a circular shape may be used, and a glass fiber cloth having no thickness may be used. In this case, the irradiation efficiency can be increased by sandwiching the germicidal lamp 19 with a cloth.

Further, the dehumidifying rotor 5 is rotated at a constant speed by a rotary motor 4 connected to the central portion, and returns to the adsorbing portion again through the adsorbing portion, the regenerating portion, and the cooling portion during one rotation. Yes. The adsorption part occupies half of the circular part of the dehumidification rotor 5 and dehumidifies the air to be treated 15 by passing through the adsorption part. Next, the regeneration unit 8 is heated by the heater 7 to release the moisture adsorbed by the adsorption unit and is regenerated. Finally, the cooling unit is naturally cooled by the outside air and can be adsorbed again. By doing so, the dehumidification rotor 5 repeats the absorption and discharge while rotating, and can continuously dehumidify the air to be treated 15.

Therefore, by rotating the deodorizing rotor 2, the entire surface of the deodorizing rotor 2 can be irradiated with light only by disposing the germicidal lamp 19 on a part of the deodorizing rotor 2. Further, by rotating about the center of the rotor, the irradiation intensity can be made uniform, and the deodorizing ability by the photocatalyst can be efficiently exhibited. The number and arrangement of the germicidal lamps 19 may be any as long as a certain deodorizing performance can be ensured, but by arranging them radially from the center of the circle as in the present embodiment, The irradiation area can be made uniform.
