Description

  The present invention relates to an antibacterial / deodorizing apparatus used for air conditioning equipment such as buildings, and more particularly to an antibacterial / deodorizing apparatus that removes germs, odors, and the like generated in a room such as a hospital or animal building.

  2. Description of the Related Art Conventionally, in an air conditioner such as a building, an air conditioning system is adopted in which indoor air is circulated while partially taking in outside air. At that time, in order to remove odors and germs generated in the room, for example, an air filter using activated carbon or the like is provided in the air circulation route. However, in the case of activated carbon or the like, if it is used for a certain period and the adsorption capacity of the activated carbon is saturated, the deodorization and sterilization performance is significantly lowered. Therefore, there is a problem that the running cost of the air conditioner increases because it must be periodically replaced with a new one. In addition, since activated carbon and the like handle fine particle powder, when it is specifically applied as an air filter, it involves refilling and replacement work, which is complicated and takes time for replacement work. On the other hand, for example, what is shown in Patent Document 1 is disclosed.

In FIG. 1 to FIG. 3 of Patent Document 1, a vertically long rectangular photocatalytic filter 7 carrying a photocatalyst such as titanium oxide is parallel to the air flow direction with a predetermined angle θ ° while providing a predetermined interval. In addition, a plurality of sheets are arranged so that the air sucked from the suction port 1 is adsorbed with odors while passing between the filters 7.

  However, according to Patent Literature 1, the photocatalyst filter has a main body formed of a thin non-woven fabric, and as shown in FIG. Therefore, when installing and installing these filters in the air flow path, it is necessary to finely position each non-woven filter and its body, etc., and adjust the air volume. There was the difficulty that it was complicated and time consuming. In addition, there is a problem that a frame having a complicated structure capable of standing and supporting several tens of the thin non-woven filter in parallel with maintaining a gap of about several mm, for example, There was a problem that the structure was complicated and the manufacturing cost was high. In addition, when maintaining the photocatalytic filter, for example, it is necessary to clean each photocatalyst, so that the maintenance work becomes complicated and the thin non-woven fabric easily breaks. There was a problem that handling became complicated. Furthermore, there has been a problem that, for example, every time maintenance work such as cleaning of the photocatalyst filter is performed, the nonwoven fabric fibers carrying the photocatalyst are gradually detached, and the adsorption capacity of the filter is likely to deteriorate.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is, for example, that the apparatus can be easily attached in the middle of the air flow path, and the maintenance work of the apparatus can be easily performed. An object of the present invention is to provide an antibacterial / deodorizing apparatus that can maintain the cost at a low cost and can be used semipermanently by recovering the adsorption capacity by a simple maintenance operation.

To achieve the above object, the present invention is interposed in an air flow path 14 is antibacterial and deodorizing device 10 for antibacterial and deodorization of air, in communication with the air flow path 14, the bottom plate member 26 and the ceiling A photocatalytic filter 16 detachably mounted on a hollow box-shaped machine casing 12 including a housing portion 32 including a member 80 and interposed in the air flow path 14, and a light source 18 installed in the vicinity of the photocatalytic filter 16. The photocatalytic filter 16 includes a thick plate-like frame body including a thick plate-like high-strength continuous void porous molded body that supports the photocatalyst and is disposed with the plate surface facing substantially perpendicular to the air flow. , projecting from the opposite direction to each other are installed respectively on opposite inner housing portion 32 the bottom plate member 26 and the ceiling member 80 of Rutotomoni, at intervals in the flow direction of the air for each of the bottom plate member 26 and the ceiling member 80 Arranged and air flow A plurality of guide members 74a provided long in a direction spatially substantially orthogonal, the photocatalytic filter 16 at the step portion formed by the guide member and their spacing of the plurality of the bottom plate member 26 and the ceiling member 80 The antibacterial / deodorizing device is provided with a plurality of guide members 74a that guide the slides in the upright state so that they can be slid in and out , and further install the light source 18 over the entire length at projecting end portions projecting in opposite directions. .

  At that time, the photocatalyst filter 16 includes a main body 22 and a support frame 24 thereof. The photocatalyst main body 22 is formed of a polygonal thick plate, and the support frame 24 of the photocatalyst filter is detachable from the polygonal thick plate. It may consist of a structure that is fitted and held on.

  The photocatalyst filter main body 22 is mounted on the lower frame 28 of the support frame 24 and is slidable along the lower frame 28 when the plate surface is disposed so as to be substantially orthogonal to the air flow. It may be.

  The light source 18 may be composed of a plurality of light emitting diode lamps 30 that are connected in parallel in the longitudinal direction of the power supply line 36 and are arranged in a long row in a direction y that crosses at least the air flow path 14.

  Further, the machine frame 12 includes a housing portion 32 that houses the support frame 24 of the photocatalytic filter, and an opening / closing door 34 that faces the housing portion 32 and hermetically seals the outside and the inside of the air flow path. The support frame 24 may be slidably inserted and removed from the outside via the open / close door 34 and may be mounted and held in the housing portion 32.

  An antibacterial and deodorizing device that is installed in the air flow path to perform antibacterial and deodorizing air, and is detachably attached to the machine frame that communicates with the air flow path. The photocatalytic filter includes a thick plate-like high-strength continuous void porous molded body that supports the photocatalyst and is disposed with the plate surface facing substantially perpendicular to the air flow. For example, in the state where the plate surface of the thick plate-like high-strength continuous void porous molded body is oriented so as to be substantially orthogonal to the air flow, a photocatalytic filter is attached to the machine frame provided in the air flow path. Since it only needs to be attached, there is no need for fine positioning air volume adjustment work, etc., as with the nonwoven fabric filter of Patent Document 1, making it easy to attach and remove the filter, and performing attachment and removal work in a very short time. Can do. In addition, since the photocatalytic filter is formed of a thick plate-like high-strength continuous void porous molded body, for example, a frame having a simple structure is not necessary, such as a frame having a complicated structure for holding a filter made of nonwoven fabric of Patent Document 1. However, since it can be held securely, the structure of the antibacterial / deodorizing device can be simplified and the cost can be reduced. Furthermore, when the adsorption capacity of the filter decreases due to use, the adsorption capacity can be easily restored to the initial state by removing the filter from the machine frame and washing the porous molded body with water, for example. Therefore, it is possible to easily perform maintenance work for restoring the adsorption capacity of the filter and to provide an antibacterial / deodorizing apparatus that can be used semipermanently. In addition, there is very little risk of damage during handling of the photocatalyst filter, and it is possible to reduce the complexity of attaching and detaching the filter, and it is not damaged and does not deteriorate the adsorption capacity.

  The photocatalyst filter includes a main body and a support frame thereof. The photocatalyst filter main body is formed of a polygonal thick plate, and the support frame of the photocatalytic filter is detachably fitted and held on the polygonal thick plate. Since the structure is composed of the structure, for example, the plate surface of the photocatalyst filter body can be securely held in the support frame in a state of being arranged so as to be substantially orthogonal to the air flow, and the filter body can be incorporated into the support frame. Removal can be performed easily.

  The photocatalyst filter main body is placed on the lower frame of the support frame so as to be slidable in and out along the lower frame when the plate surface is disposed so as to be substantially orthogonal to the air flow. Since it is a structure, the photocatalyst filter main body can be attached to or removed from the support frame by a simple operation of sliding the filter on the lower frame of the support frame and taking it in and out. It can be done in a short time.

  Further, the light source is composed of a plurality of light emitting diode lamps connected in parallel in the longitudinal direction of the power supply line and installed in a long line at least in a direction crossing the air flow path, so that the photocatalytic filter main body is activated. Therefore, even if the light-emitting diode lamp is turned on, the amount of heat generated is smaller than that of, for example, a fluorescent lamp, so that the safety during use is increased and the range of application to places where use has been limited due to conventional heat generation is widened. . Further, since the light emitting diode lamps are arranged in a row in the longitudinal direction of the power supply line, the light emitting diode lamps can be arranged according to the structure of the installation location, for example, the power supply lines are bent and arranged. The degree of freedom of mounting increases.

  The machine frame includes an accommodating portion for accommodating the supporting frame itself of the photocatalytic filter, and an open / close door that opposes the accommodating portion and hermetically seals the outside and the inside of the air flow path. Since it is a structure that can be slidably inserted and removed from the outside through the door and is mounted and held in the storage part, for example, it can be mounted in and out of the storage part while opening the open / close door and sliding the support frame of the photocatalyst filter. Installation and removal operations of the photocatalytic filter can be facilitated, and the assembly time and maintenance work time can be shortened.

  Hereinafter, the best mode for carrying out the present invention will be described. In the antibacterial / deodorizing apparatus of the present invention, a photocatalytic filter including a plate-like high-strength continuous void porous molded body carrying a photocatalyst is disposed with the plate surface of the filter facing the air flow so as to be substantially orthogonal to the air flow. In such a state, the device can be detachably attached to the machine frame provided in the air flow path, so that, for example, the apparatus can be easily attached in the middle of the air flow path and the maintenance work of the apparatus can be easily performed. The maintenance cost can be kept low, and it can be used semipermanently by recovering the adsorption capacity by simple maintenance work.

  FIG. 1 thru | or FIG. 9 has shown embodiment of the antibacterial and deodorizing apparatus which concerns on this invention, and in this embodiment, as shown in FIG. It is implemented in the middle of the air flow path 14 to be circulated in the room. In FIG. 9, the machine casing 12, which is separate from the duct 44 forming the air flow path 14, is connected to the duct 44 and the photocatalytic filter 16 is mounted in the machine casing 12. An opening may be provided in the middle of 44 and the photocatalytic filter 16 may be directly mounted in the duct 44 through the opening. In the present embodiment, the antibacterial / deodorizing apparatus includes a photocatalytic filter 16, a light source 18, and a thick plate-like high-strength continuous void porous molded body (hereinafter referred to as “molded body”).

In the present embodiment, the photocatalytic filter main body 22 is composed of a polygonal thick plate, and the polygonal thick plate is composed of the above-described molded body. The photocatalytic filter body 22 can be obtained as follows. First, for example, polyurethane foam is formed into a substantially square thick plate shape having a side of about 30 cm with a thickness of about 3 cm to 5 cm, for example, and this is dispersed in water or the like together with an organic binder, for example. The prepared ceramic slurry is impregnated and then dried and fired to form a ceramic porous molded body. Next, the ceramic porous molded body is dipped in a titanium oxide sol in which particles such as titanium oxide as a photocatalyst material are dispersed in water or a solvent, and these titanium oxides are coated on the surface of the molded body. The molded body can be obtained by baking. Therefore, for example, the photocatalyst filter main body 22 is arranged so that its plate surface is substantially orthogonal to the air flow, and the air passing through the photocatalytic filter main body 22 is a continuous gap (not shown) formed in the porous portion. The fungi and odor components in the air can be sufficiently adsorbed on the surface of the porous portion while passing through. In addition, since the photocatalyst filter main body 22 of the present embodiment is formed of a rectangular thick plate (FIG. 4), for example, a complicated structure for holding the main body 22 in a state oriented in a direction orthogonal to the air flow. This eliminates the need for the frame, and simplifies the structure of the antibacterial / deodorizing device. The photocatalyst filter main body 22 has such a strength that it will not be damaged even if it hits the machine frame 12 or the like during handling. Further, when the decomposition / adsorption ability is lowered after use to some extent, the surface of the photocatalyst filter main body 22 is washed with, for example, water, so that the adsorbed substance on the surface is washed away and the decomposition / adsorption ability is easily recovered. be able to. In addition, the dimension of this photocatalyst filter main body 22 can be set to the arbitrary dimension according to the cross section of an air flow path, the flow volume of the air which passes there, etc. not only the thing of this embodiment. The photocatalytic filter main body is not limited to the substantially square thick plate shape of the present embodiment, but may be formed in a polygonal shape such as a rectangle or a hexagon, or a circular thick plate shape.

  In the present embodiment, the support frame 24 detachably fits and holds the photocatalytic filter main body 22. As shown in FIG. 3, the support frame 24 is formed in a square shape as viewed from the front so that, for example, four photocatalyst filter bodies 22 can be held. The photocatalytic filter 16 in which the photocatalytic filter main body 22 is supported by the support frame 24 is a thick plate frame. More specifically, as shown in FIGS. 3 and 4, for example, three H steel members having a length that is approximately twice the lateral side of the photocatalytic filter main body 22 and a width that is slightly wider than the width of the photocatalytic filter main body 22. 60 in a horizontal direction, arranged in three rows parallel to the upper, middle, and lower sides of the photocatalyst filter main body 22 with an interval of the length of the substantially vertical side thereof. These H steel members 60 and 62 are connected and fixed by, for example, welding or the like in a state where the vertical H steel members 62 that are horizontally mounted are arranged. Next, as shown in FIGS. 3 and 4, the U-shaped cross-section member 64 having substantially the same length and width as the vertical H steel member 62 described above, and both end portions of the horizontal H steel member 60 in the vertical direction, respectively. Place it horizontally. At that time, as shown in FIG. 4, the U-shaped member 64 described above has a lower end at the both ends of the lowest horizontal H steel member 60, for example, a pin that penetrates the horizontal H steel member 60 in the width direction. The member 66 is pivotally supported while being pivotally supported. Then, as shown in FIG. 4, the U-shaped member 64 is pivotally supported by the pin member 66 and rotates on the vertical surface, and its upper end is located at both ends of the horizontal H steel member 60 positioned in the uppermost row. The screw members 68 are detachably connected to each other. Therefore, as shown in FIG. 4, if the U-shaped member 64 is pivotally supported to be in a horizontal state, the photocatalytic filter body 22 can be detachably mounted between the horizontal H steel members 70 described above. At that time, as shown in FIG. 4, in a state where the photocatalytic filter main body 22 is erected, the lower side of the photocatalyst filter main body 22 can be slid so as to be sandwiched between, for example, grooves of the H steel member 60. That is, the photocatalytic filter main body 22 can be easily slid in and out along the lower frame 28 using the H steel member 60 and the U-shaped member 64 as the lower frame 28. The number of photocatalyst filter bodies supported by the support frame can be any number, and the shape of the support frame is not limited to the shape of the present embodiment, but the number of photocatalyst filter bodies to be mounted. Depending on the shape and the like, it may be formed in a polygonal shape such as a rectangle or a hexagon or a circular shape in front view, for example.

A ceiling member 80, which is suspended and fixed and has the same structure as the bottom plate member 26 and provided with guide members 74a and 74b, is disposed to face the bottom plate member 26, and is fixed to the other end side of these columns. Therefore, as shown in FIG. 5, the accommodating portion 32 is a state in which the short side of the bottom plate member 26 is used as the inlet / outlet 82 of the support frame 24 of the photocatalyst filter, and the support frame 24 of the photocatalyst filter is erected on the bottom plate member 26. Thus, it is possible to slide in and out of the accommodating portion 32 while being guided by the guide members 74a and 74b. The photocatalytic filter 16 is guided by a step portion formed by the plurality of guide members 74a and 74b and the distance between the bottom plate member 26 and the ceiling member 80 . As shown in FIG. 5, the accommodating portion 32 includes a side plate 78 that closes the entrance / exit 82, and the side plate 78 is detachably fixed to the column 76 with screws or the like.

At that time, a prefilter 46 and an afterfilter 48 described later may be accommodated together. Therefore, the machine frame main body 38 is formed of a square columnar steel box having a size that can accommodate the accommodating portion 32 and the other filters 46 and 48. Further, as shown in FIGS. 1 and 2, the machine frame main body 38 has one surface of the box as a work opening 52 to allow the photocatalytic filter 16, the prefilter 46, and the like to be taken in and out. As shown in FIG. 2, the machine casing main body 38 is connected to the duct 44 by providing connection pipes 53 on opposing surfaces on both sides of the work opening 52. Therefore, as shown in FIG. 2, the air that has flowed through the air flow path (44) flows in the machine casing 12 from the IN side to the OUT side. As shown in FIGS. 1, 2, and 6, the accommodating portion 32 is configured such that the plate surface of the main body 22 is substantially orthogonal to the air flow described above in a state where the photocatalytic filter main body 22 is accommodated in the accommodating portion 32. For example, the guide member 40 is sandwiched and disposed in the machine frame body 38 near the center of the lateral side of the work opening 52. As shown in FIGS. 1 and 2, it is desirable to provide a pre-filter 46 in front of the photocatalytic filter 16 so that the porous portion of the photocatalytic filter 16 is not clogged with dust generated in the room. Furthermore, as shown in FIGS. 1 and 2, for example, an after filter 48 may be provided behind the photocatalytic filter 16 to prevent dust from entering the room or the like. Further, the machine frame main body 38 is not limited to the quadrangular columnar shape in the present embodiment, but may be formed in a columnar shape corresponding to the shape of the accommodating portion, or may be formed in a polygonal columnar shape such as a hexagonal columnar shape. Moreover, it is not limited to steel but may be made of other metals such as stainless steel or synthetic resin.

Therefore, if the photocatalyst filter support frame 24 is attached to the housing portion 32, the light from the light emitting diode lamp 30 is uniformly irradiated from the upper side and the lower side of the photocatalyst filter 16 to uniformly activate the photocatalyst. . As the light emitting diode lamp 30, a known light emitting diode lamp can be used. When the photocatalyst is titanium oxide, for example, a light emitting wavelength of 380 nm or less is selected. Is preferably selected. As described above, the use of the light emitting diode lamp 30 makes it possible to reduce the amount of heat generation compared to a conventional fluorescent lamp or the like, and there is an application range to places where use has been limited due to conventional heat generation. spread. Further, since the lamp units 84 are arranged in a row at a predetermined interval along the longitudinal direction of the power supply line 36, the power supply line 36 is formed of, for example, a known electric cord having flexibility and flexibility. The power supply line 36 can be bent and arranged as necessary, such as unevenness of the foundation, and the degree of construction freedom is increased. In the present embodiment, the light source 18 has the light emitting diode lamp unit 84 as a unit. However, the present invention is not limited to this. For example, the individual light emitting diode lamps 30 are assembled in a mesh shape and close to the plate surface of the photocatalytic filter. It may be arranged so as to irradiate the entire plate surface, or a reflector or the like may be arranged at a required position. Further, as shown in FIG. 8, a known mercury lamp 86 or the like may be used.

At this time, the support frame 24 of the photocatalyst filter is guided to be slidable in and out from the outside via the open / close door 34, and is mounted and held in the accommodating portion. Thereafter, as shown in FIG. 7, the entrance / exit 82 of the housing portion 32 is closed by the side plate 78. Next, if necessary, a pre-filter 46 and an after-filter 48 are attached, and the work opening 52 is hermetically sealed with the open / close door 34. After that, for example, when the fan (FIG. 9) is in an ON state, the light source 18 is turned on and the photocatalytic filter 16 is activated to perform air circulation. At that time, for example, a differential pressure gauge may be installed on the IN side and the OUT side of the antibacterial / deodorizing apparatus to notify the maintenance timing of the photocatalytic filter 16. Then, if necessary, the photocatalyst filter support frame 24 is slidably pulled out from the accommodating portion 32, and the photocatalyst filter main body 22 is removed as shown in FIG. The photocatalyst filter main body 22 itself is removed from the support frame 24 and washed with water or the like to recover the decomposition / adsorption ability and can be reused.
