There are those that use adsorption and deodorization with activated carbon, those that incinerate odor generating components, those that use ozone-decomposing effects, and those that use microorganism-decomposing effects. Recently, a lamp using a metal oxide film having a photocatalyst such as titanium oxide formed on the bulb surface has been used, and a lamp that emits light in a predetermined wavelength range and a light receiving portion in the vicinity of the lamp with a photocatalytic substance interposed therebetween. Some have parts and filters. In this method, a substance that is a source of odor is brought into contact with a catalytic substance excited by light of a specific wavelength range to decompose the catalyst substance into another substance having no odor. In order to increase the deodorizing effect from this operating principle, it is important that the odor-causing substance is brought into efficient contact with the excited photocatalytic substance, but the odor-causing substance that is diffused into the atmosphere must be removed. It is not possible to individually control and contact this photocatalytic substance. Therefore, the design is performed based on the statistical method of gaseous matter theory so that the odor molecules are decomposed to such an extent that they do not cause discomfort to human odor.

As a result, it has been attempted to apply the above technology to deodorization of odors generated from livestock barns. The present applicant has developed a photocatalytic deodorizing device, which is one of them, and has previously applied for a patent as Japanese Patent Application No. 11-241610. Although this has a single function as a deodorizing device, this photocatalytic deodorizing device mainly uses a fluorescent lamp as a light source, and a large number of fluorescent lamps for lighting are separately used in a livestock barn. Therefore, such a mode is a wasteful use, and it is desired to save resources of the equipment.

It is understood that it is proportional. The mechanism of deodorization by photocatalysis is such that electrons are transferred when odor molecules come into contact with a photocatalyst substance such as a metal oxide excited by light of a specific wavelength such as an ultraviolet region, and the odor molecules are decomposed or otherwise decomposed. Or change to a different substance with no smell. The phenomenon that odor substances are converted to other odorless substances means that odor molecules diffused in the air must come into contact with the photocatalytic substance in the excited state, and promoting this contact will have a deodorizing function. Will increase. Contact is related to the gas flow, which is the macroscopic movement of air, and the behavior of the individual gas molecules that make up the air, but it is not possible to control individual molecules of odorants to promote contact. . Therefore, it is necessary to statistically deal with it based on the gaseous matter theory. The lower the flow rate of air to the photocatalytic substance, the higher the contact probability. The longer the residence time of air in the deodorizing device, the higher the contact probability. Becomes higher. In addition, depending on the type of the odorous substance, decomposition may not be completed by a single contact and may require a plurality of contacts.

This was installed in the exhaust passage, but since this light source is used exclusively for exciting the photocatalyst, the lamp for indoor lighting will be installed separately, and the use of light can be said to be effective. Did not. In view of this point, the present invention has considered that a photocatalytic substance is interposed around the lighting lamp so that the odor gas is exhausted therethrough so that the deodorizing function and the lighting function are combined. However, the wavelength of light suitable for light excitation is in the ultraviolet range, and the wavelength of light suitable for illumination is in the visible light range. Therefore, it is necessary to select a light source having both wavelength ranges. Moreover, it is desirable to exclude light in the ultraviolet region that is harmful to living organisms from the illumination light. Also, the collision of the odor molecules with the photocatalytic substance means the contact between the odor molecules and the photocatalytic substance. Therefore, it is advantageous to increase the chance of collision by making the gas flow flowing in the exhaust path having the deodorizing function flow in a turbulent state instead of a laminar flow. For this reason, in the present invention, the gas flow is turbulent in a non-linear manner so as to promote collision with the flow channel wall surface formed of the photocatalytic substance, and the gas flow is turbulent, or an appropriate baffle plate is provided. I am trying to do it.

以下とすることが必要である。First, an outline of the deodorizing lighting system of the present invention is shown in FIG. 1 as an example applied to a pig house. 1 is a so-called windowless barn with no windows so that odor does not diffuse to the surroundings, 2 is an outside air inlet opened at the upper part of the outer wall, and 3 is an exhaust vent installed higher than the roof of a private house. It is a chimney. A blower 4 for inhaling outside air is installed in the vicinity of the air introduction port 2, and an air supply port 5 appropriately provided on the ceiling 10 so as to supply air to the whole barn. A louver 6 for determining the direction of the ventilation flow is fitted. In the barn, a passage 7 for workers is provided at the center, and pig bunches 8 are partitioned by partition walls 9 on both sides. Large pigs have a space of one to several pigs, and piglets have a space of about ten and several pigs. The floor of the pig bun 8 is a snowboard 11, and the excrement of the pig falls under the floor and is collected in the feces removal pit 12. The outside air is taken into the ceiling from the air inlet 2 by the blower 3 and supplied to the livestock room through the air supply hole 5. The fresh air is sent downward by the louver 6, and the air in the barn passes through the floor's mushroom 11 and the pit 12 where wastes accumulate, and partly through the exhaust window 13 on the side wall.
And then sent to the deodorizing mechanism 20 to be deodorized and the chimney 3
Is discharged from the outside. The main source of the malodor coming out of the barn is the excrement in the pit 12, so that ventilation and deodorization of the odorous substances are important points of this system so that the air in this part does not flow into the room. Since the deodorizing treatment of the present invention is performed in the process of passing through the exhaust path, the flow rate of the exhaust path has a close relationship with the deodorizing effect, and the appropriate flow rate is controlled by disposing a blower at an appropriate place. . This flow rate adjustment affects the gas flow velocity in the stable, and in the case of pigs, there is a problem that a cold is caught when the flow rate becomes 0.45 m / sec or more. Therefore, when designing, the ventilation flow rate in the livestock room is a value required to ensure the deodorizing effect, and the standard is 0.1 m / sec or more, and the upper limit (0.45 m for pigs) that does not cause colds to livestock / Sec)

成とすることも可能である。The deodorizing mechanism 20 includes a fluorescent lamp 21 installed on the ceiling 10 or the like, which also serves as an illumination source and an excitation light source for the photocatalyst, and the fluorescent lamp 21.
An exhaust passage 22 formed so as to surround 21 and a photocatalytic substance such as titanium oxide coated on a light receiving surface such as a wall surface of the exhaust passage 22. The exhaust containing the odorous substance in the livestock barn passes through the vicinity of an illumination lamp installed on the ceiling or the like, and in the meantime, the decomposition action of the photocatalyst promotes the decomposition of the odorous substance, and the exhaust is exhausted from the chimney 3. The wavelength of light that is effective for exciting the photocatalyst is in the ultraviolet region, but considering the lighting function, the light in this region is not visible light, so it is not only suitable for lighting but also health-friendly for livestock and workers. There is no light. Therefore, the light source employed in the present invention employs a light source including an ultraviolet region to a visible light region in order to secure a deodorizing function, but for illumination, the ultraviolet region is blocked and only light in the visible light region is irradiated into the barn room. It is devised so that. The present applicant has confirmed the phenomenon that most of the light in the ultraviolet region once contacted with the photocatalytic substance is absorbed by the photocatalytic substance as excitation light.
Based on the knowledge, the lighting employs an indirect illumination mode in which direct light from a light source does not enter the room, and employs an ultraviolet shielding mechanism such as an ultraviolet shielding filter in an illumination cover. In the present invention, it is not necessary to unify all light sources with the same lamp, and as described above, the wavelength ranges of light for illumination and for excitation of photocatalyst are different, so that lamps having different emission wavelength ranges are appropriately combined. The balance between the deodorizing function and the lighting function can also be adjusted. As an embodiment of the present invention, for indoor ventilation with a low odor, a route for exhausting directly from the chimney without going through the deodorizing treatment mechanism may be provided, and conversely, when the odor is not enough and the device of the present invention alone is insufficient. It is also possible to adopt a configuration in which a pretreatment mechanism using another type of deodorizer such as a corona discharge deodorizer presented in Japanese Patent Application No. 11-241610 previously filed by the present applicant is also possible.

変良いものとなる。Embodiment 1 In the embodiment of the present invention shown in FIG. 2, fresh outside air is taken in from an outside air inlet 2 provided on the outer wall behind the ceiling, and supplied to the livestock room through an air supply port 5 in the ceiling 10 part. The indoor air passes through the floor 11 under the livestock floor, the pit 12 and the ceiling 10
A ventilation path exhausted from the chimney via an exhaust path 20, which is a deodorizing treatment mechanism, is set so as to go around a fluorescent lamp row 21 for illumination installed in the room. That is, a rectangular air supply port 5 having a width of 90 cm is provided in the ceiling section directly above both rows of stalls and in the longitudinal direction of the barn, and a lattice-shaped louver 6 is attached to the air supply port 5. On the outer wall side of both air supply ports 5, a peak wavelength in an output wavelength range of 300 to 600 nm generally used as a moth lamp.
A tubular 40W fluorescent lamp emitting 440 nm light is arranged line by line, and an exhaust passage surrounding the fluorescent lamp is formed. Also, right above the passage in the center of the barn, two rows of fluorescent lights are arranged,
A total of four rows of fluorescent lamps are illuminated. In the exhaust passage of this embodiment, the gas in the barn is collected at one corner of the barn by a duct, and first passes through the exhaust passage surrounding the row of fluorescent lamps along the outer wall as shown in FIG. And make a U-turn so that it passes through the exhaust path surrounding the central fluorescent lamp row, and after returning to one end of the barn, passes through the exhaust path surrounding the other central fluorescent lamp row, and the other end at the other end of the barn Then, a U-turn is made so as to wind around the air supply port, and the air is exhausted from the chimney via a blower provided at a corner at one end through an exhaust passage surrounding the row of fluorescent lamps along the outer wall on the opposite side. As described above, since the exhaust gas containing the odorous substance is subjected to the decomposition treatment by the photocatalytic substance in the process of passing through the long exhaust path constituting the deodorizing treatment mechanism, the deodorizing efficiency becomes very good.

This figure is a cross-sectional view of the exhaust path, and the exhaust path 22 is a rectangle (15 cm × 100 cm) surrounded on all sides by walls.
m), an opening window is formed at one end of the lower surface, and an ultraviolet blocking filter 24 made of polycarbonate serving as an illumination cover covers the portion. A film in which anatase-type titanium oxide (TiO2) as a photocatalytic substance is coated on one side is attached to the entire inner surface of the wall, and a fluorescent lamp 21 serving as a light source is installed near the wall opposite to the opening. This exhaust path has a deodorizing function. As can be seen from the figure, the wall on the opening side is slightly extended so as to block the direct light of the light source to form a direct light shielding portion 23, so that the light from the fluorescent lamp is always covered with the photocatalytic substance. Thus, the direct light does not go outside. Although the light reflected on the wall does not substantially include the ultraviolet region, the light in the ultraviolet region that is slightly left is also cut by the ultraviolet cutoff filter 24, so that the illumination light that illuminates the interior of the barn is an ultraviolet light that is healthy. Is not included. In addition, as for the deodorizing function, the exhaust path of a long distance that makes two round trips in the longitudinal direction of the large ceiling is the deodorizing mechanism, and the gas containing the odor is meandering there, so that the odorous substances are It comes into contact with the photocatalytic substance in the excited state and is decomposed. If the exhaust path has a long straight section, the exhaust flow becomes laminar, and if the contact between the odorant and the photocatalytic substance is not sufficient, the exhaust path alternately forms a comb-like shape from the upper wall and the lower wall. If a baffle is planted to create turbulence, contact can be encouraged.

以下となるようにする。[0012] The pig tress is 2.5m x 2m, and is separated by a partition 9 at an interval of 2m from an adjacent one and is put in an appropriate number. The height from the ceiling to the floor is 2 m, and a pit 12 is provided below the floor of the snowboard 11 so as to be inclined toward the outer wall, and a pit 12 for collecting manure is provided along the outer wall. The depth of the pit 12 is 50 cm below the floor. The length in the longitudinal direction of the barn room can be changed in design depending on the number of pigs to be bred, but in this embodiment, it is 12 m. The excrement that falls from the gap between the snowboards 11 flows on the inclined concrete floor and is stored in the pits 12. Fresh air taken in from the outside air inlet 2 by the action of the blower 4 is sent into the room from two air supply ports 5 from above the ceiling. At this time, since the lattice-shaped louver 6 is attached to the air supply port 5, the air is rectified downward and is sent. On the other hand, on the exhaust side, air is taken in by a blower 4 ′ installed near the chimney, and the blower installation part is connected to the pit 12 part via an exhaust path constituting the deodorization processing mechanism part 20 of the ceiling part 10. The air in the pit 12, which is the largest odor source, flows to the exhaust path side, and hardly flows into the room and drifts. Further, in this embodiment, the air in the stable is communicated to the exhaust path from the exhaust port 16 provided in a part of the side wall. By controlling the two blowers 4, 4 ', the ventilation flow rate in the livestock room is the value required to secure the deodorizing effect.

い。According to the present invention, an exhaust passage is formed so as to surround a number of illumination lamps installed in a barn room, and a photocatalytic substance is interposed on a surface to be irradiated with the lamp, and the exhaust passes through the exhaust passage. Since odor substances are decomposed by photocatalysis in the process, most odor substances can be effectively decomposed in the process of passing through a long exhaust path. If the exhaust flow is laminar and the deodorizing function is low because the flow rate is small and the straight part of the exhaust path is long, a baffle plate is arranged in the flow path to create turbulent flow to enhance the deodorizing function. I can do it. In addition, the deodorizing treatment mechanism using the exhaust path does not need to secure a special installation place, and only needs to pipe the ceiling or the wall where the illumination lamp is installed.

However, since the interior of the barn is illuminated via an ultraviolet shielding member, It does not harm the health of livestock and workers. If the exhaust path wall surface is coated with a photocatalytic substance and the direct light of the light source lamp is formed so as not to irradiate the interior of the livestock barn, the light of the illumination part is always reflected light of the wall part, and this reflected light is The ultraviolet region is almost completely absorbed by the photocatalytic substance, and when the ultraviolet shielding filter is adopted for the illumination cover, even a small amount of the residual ultraviolet can be completely cut off.
