Japanese Patent No. 2653300

  However, in the conventional ozone deodorizing apparatus, it is necessary to provide an ozone generator and an ozone circulation path outside the duct. For this reason, this ozone deodorizing apparatus has a problem that it takes time to install. In addition, in the conventional ozone deodorizing apparatus, the honeycomb filter rotates, and therefore, the sealing member that seals the duct and the honeycomb filter may be worn. For this reason, it is assumed that it is necessary to frequently replace the seal member. An object of the present invention is to provide an ozone deodorizing mechanism that does not require time and labor for installation in a duct and can prevent a seal member that seals a duct and a honeycomb filter from being worn.

  The ozone deodorizing mechanism according to claim 1 includes an adsorption part, an ozone generation part, an ozone supply path, an ozone recovery part, an ozone circulation path, and an ozone circulation part. The adsorption part adsorbs odor molecules. The adsorbing portion referred to here is, for example, a honeycomb filter having an odor adsorbing material such as zeolite. The ozone generation unit generates ozone. The ozone supply path is a path for supplying ozone to the adsorption unit. The ozone recovery unit faces the outlet of the ozone supply path via the adsorption unit. Moreover, this ozone collection | recovery part collect | recovers the ozone which passed the adsorption | suction part. The ozone circulation path connects the ozone recovery part and the ozone supply path by piping. The ozone circulation unit supplies the ozone recovered by the ozone recovery unit to the ozone supply path. In addition, the ozone circulation part here is a blower, a circulation pump, etc., for example. And the ozone production | generation part and an ozone circulation part are provided in any one of an ozone supply path, an ozone collection | recovery part, and an ozone circulation path. The ozone circulation path penetrates the adsorption part. The ozone supply path and the ozone recovery section are rotatable around the ozone circulation path with a part of the adsorption section and the outlet of the ozone supply path facing each other.

  Here, the ozone generation part and the ozone circulation part are provided inside any one of the ozone supply path, the ozone recovery part, and the ozone circulation path. Moreover, the ozone circulation path penetrates the adsorption part. And an ozone supply path and an ozone collection | recovery part can be rotated centering on an ozone circulation path in the state where a part of adsorption part and the exit of the ozone supply path opposed. For this reason, an ozone deodorizing apparatus and an ozone circulation path can be made into one unit. Therefore, the apparatus provided with the present ozone deodorizing mechanism can be easily installed in the duct. Here, the adsorption unit is fixed, and the ozone supply path and the ozone recovery unit are rotatable. Therefore, the seal member that seals the duct and the suction portion is not worn. As described above, the present ozone deodorizing mechanism does not require time and labor for installation in the duct, and can prevent the seal member that seals the duct and the adsorbing portion from being worn.

  The ozone deodorizing mechanism according to claim 2 is the ozone deodorizing mechanism according to claim 1, wherein the ozone generation part and the ozone circulation part are provided inside the ozone circulation path.

  Here, the ozone generation unit and the ozone circulation unit are provided inside the ozone circulation path. That is, the ozone generation unit and the ozone circulation unit do not rotate. Therefore, the fear that the electrical wiring from the ozone generation unit and the ozone circulation unit may be entangled can be eliminated.

  The ozone deodorizing mechanism according to claim 1 does not require time and effort for installation in the duct, and can prevent the seal member that seals the duct and the adsorbing portion from being worn.

  In the ozone deodorizing mechanism according to the second aspect, it is possible to eliminate the risk that the electrical wiring from the ozone generation unit and the ozone circulation unit will be intertwined.

[Configuration of ozone deodorizer]
A longitudinal sectional view of an ozone deodorizing apparatus according to an embodiment of the present invention is shown in FIG. 1, and a top view is shown in FIG.

  As shown in FIGS. 1 and 2, the ozone deodorization apparatus 1 mainly includes an ozone generation chamber 130, an ozone supply chamber 110, an ozone recovery chamber 120, and a deodorization honeycomb filter 40.

[Components of ozone deodorizer]
(1) Ozone generation chamber The ozone generation chamber 130 is a cylindrical body, and a donut-shaped partition plate 90 is provided in the vicinity of the center inside. An ozone generator 131 is provided on the upper part of the partition plate 90. The ozone generator 131 is, for example, a corona discharger, a plasma discharger, a creeping discharger, a glow discharger, or a streamer discharger.

  Further, the ozone generation chamber 130 is provided with a blower 32 so as to penetrate the partition plate 90. The blower 32 is arranged so that the suction port is at the lower part of the partition plate 90 and the blower outlet is at the upper part of the partition plate 90. The blower 32 circulates ozone generated by the ozone generator 131 in the chambers 110, 120, and 130.

  As shown in FIG. 2, the electrical cord of the ozone generator 131 passes through a part of the side wall of the ozone generation chamber 130 and is guided to a wiring protection member 145 provided in the same plane as the deodorizing honeycomb filter 40. Connected to an external power supply.

(2) Ozone supply chamber The ozone supply chamber 110 is formed by joining a shape body obtained by cutting a hollow cone into a fan shape to a shape body provided with a lid on a tapered cylindrical body. The hollow portion of the former shape body and the hollow portion of the latter shape body communicate with each other. Among these, the former shaped body portion is fitted into the upper part of the ozone generation chamber 130 and sealed with the chamber sealing material 37. On the other hand, an ozone outlet 111 is provided at the bottom of the latter shape body. The ozone outlet 111 is an opening group for blowing out ozone generated by the ozone generator 131 to the deodorizing honeycomb filter 40.

(3) Ozone recovery chamber The ozone recovery chamber 120 is formed by joining a shape body in which a hollow cone is cut out in a fan shape to a shape body in which a lid is provided on an upper portion of a tapered cylindrical body. The hollow portion of the former shape body and the hollow portion of the latter shape body communicate with each other. Of these, the former shaped body portion is fitted into the lower portion of the ozone generation chamber 130 and sealed with the chamber sealing material 37. On the other hand, an ozone recovery port 121 is provided at the bottom of the latter shape body. The ozone recovery port 121 is an opening group for recovering ozone flowing from the ozone outlet 111 through the deodorizing honeycomb filter 40.

(4) Deodorizing Honeycomb Filter As shown in FIG. 2, the deodorizing honeycomb filter 40 has a honeycomb structure, and the inner wall thereof is coated with an odor adsorbing material such as zeolite. The kind of the odor adsorbing material is selected according to the odor molecule to be adsorbed. In general, zeolite is known to be an excellent adsorbing material for polar odor molecules such as ammonia, amine, mercaptan and the like. Further, the hydrophobic zeolite is chemically a crystal of an aluminosilicate metal salt, and the oxygen atom in the silica structure has almost no basicity and does not participate in the formation of hydrogen bonds. For this reason, the Si—O—Si bond on the surface of the hydrophobic zeolite exhibits water repellency and has a characteristic of reducing the amount of moisture adsorption.

[Operation of ozone deodorizer]
As shown in FIGS. 1 and 2, an annular belt mounting portion 150 is joined to the ozone supply chamber 110 (note that the annular belt mounting portion 150 is fixed to the hollow shaft 91). An annular belt 55 is hung on the mounting portion 150. The annular belt 55 is also put on the pulley 60. The pulley 60 is coupled to the motor 70 via the shaft 65. Therefore, when the motor 70 is driven, the pulley 60 rotates and the annular belt 55 is driven. As a result, the ozone supply chamber 110 rotates and moves. Since the ozone recovery chamber 120 is joined to the ozone supply chamber 110 by the hollow shaft 91, the ozone recovery chamber 120 rotates with the ozone supply chamber 110.

[Operation of ozone deodorizer]
In the present ozone deodorization apparatus 1, the ozone supply chamber 110 and the ozone recovery chamber 120 rotate at a constant speed around the ozone generation chamber 130, and are used for deodorization by ozone supplied from the ozone generator 131 through the ozone outlet 111. Odor molecules adsorbed on the honeycomb filter 40 are sequentially decomposed. In addition, the flow of ozone in the chambers 110, 120, and 130 at this time is represented by white solid arrows in FIG.

In the ozone deodorizing apparatus 1 according to the previous embodiment, the ozone concentration in the chambers 110, 120, and 130 was not strictly controlled, but the ozone generator 131 was surrounded by a box having a window, and the window was opened and closed. Thus, the ozone concentration in the chambers 110, 120, and 130 may be controlled to some degree strictly. The opening and closing of the window may be performed by blowing up the window by turning on / off the small fan, or may be simply performed mechanically.

  In addition, a window is provided in the vicinity of the joint portion between the shape body in which the lid is provided on the tapered cylindrical body of the ozone supply chamber 110 and the shape body in which the hollow cone is cut out in a fan shape (note that In this case, it is not necessary to surround the ozone generator 131 with a box), and the window may be opened and closed by a predetermined centrifugal force.

(B)
In the ozone deodorizing apparatus 1 according to the previous embodiment, the blower 32 is used for the circulation of ozone, but a circulation pump may be used instead.

(C)
In the ozone deodorizing apparatus 1 according to the previous embodiment, the motor 70 rotationally drives the ozone supply chamber 110 and the ozone collection chamber 120 via the pulley 60, but the motor 70 is joined to the center of the annular belt mounting portion 150. The ozone supply chamber 110 and the ozone recovery chamber 120 may be directly driven to rotate.

(D)
In the ozone deodorization apparatus 1 according to the previous embodiment, the ozone generator 131 and the blower 32 are provided inside the ozone generation chamber 130. However, the ozone generator 131 and the blower 32 are provided with the ozone supply chamber 110 and the ozone recovery chamber. It may be provided inside 120.

(E)
In the ozone deodorization apparatus 1 according to the previous embodiment, ozone circulated in the chambers 110, 120, and 130. However, as shown in FIG. May be discharged.

Further, the partition plate 90 completely partitions the upper and lower sides of the ozone generation chamber 130.

(F)
The ozone deodorization apparatus 1 according to the previous embodiment is provided with the ozone recovery chamber 120. However, the ozone deodorization apparatus may be configured without the ozone recovery chamber 120 as shown in FIG. In the ozone deodorizing apparatus 4, it is necessary to provide an ozone decomposition catalyst-carrying filter 43 on the downstream side in the ozone flow direction of the deodorizing honeycomb filter 40 for safety. The ozone decomposition catalyst-carrying filter 43 is, for example, an activated carbon filter and plays a role of decomposing ozone.

(G)
In the ozone deodorizing apparatus 1 according to the previous embodiment, the ozone supply chamber 110 and the ozone recovery chamber 120 rotate while sandwiching the deodorizing honeycomb filter 40.

As shown in FIGS. 5 and 6, the ozone supply chamber 410 and the ozone collection chamber 420 are joined to the chamber guide 470 via a connecting member 490. The chamber guide 470 is fixed to a predetermined location of the guide wire 480. The guide wire 480 is fixed to the drive shafts 461 and 462. A motor 570 is attached to the upper drive shaft 461. Therefore, when the motor 570 is rotated forward (reversely), the guide wire 480 is wound up, and as a result, the chamber guide 470 is raised. As described above, since the ozone supply chamber 410 and the ozone collection chamber 420 are joined to the chamber guide 470 by the connecting member 490, the ozone supply chamber 410 and the ozone collection chamber 420 are also raised as the chamber guide 470 is raised. It will be. Further, when the motor 570 is reversely rotated (forward rotation), the guide wire 480 is opened, and as a result, the chamber guide 470 is lowered. Accordingly, the ozone supply chamber 410 and the ozone recovery chamber 420 are lowered accordingly. The lower drive shaft 462 has a mechanism for spontaneously winding the guide wire 480 so that the guide wire 480 does not sag when the chamber guide 470 is lowered.

  The chamber guide 470 is provided with motor changeover switches 475 at both ends in the vertical direction, and the motor changeover switch 475 is pushed in contact with the drive shafts 461 and 462, thereby rotating the motor 570 forward / reversely. It is designed to switch.

  Further, as shown in FIG. 7, a configuration without the ozone recovery chamber 420 may be used. In the ozone deodorizing apparatus 6, it is necessary to provide an ozone decomposition catalyst-carrying filter downstream of the deodorizing honeycomb filter 440 in the ozone flow direction for safety. The ozone decomposition catalyst-carrying filter is, for example, an activated carbon filter and plays a role of decomposing ozone.
