Description

  The present invention relates to a deodorizing apparatus that eliminates odors, and relates to a deodorizing apparatus that can deodorize or deodorize bad odors and unpleasant odors using the light of an arc light.

  In pachinko shops, movie theaters, theaters, etc., where many people gather and smoke and body odors tend to be stored, deodorization measures are required to create comfortable spaces. In addition, deodorization measures are a serious problem for residents living in the vicinity of facilities that tend to produce bad odors, such as poultry farms, meat processing, and industrial waste processing plants.

In such cases, odors are reduced by masking odors with fragrances using fragrances, or by reducing odors using chemical deodorants as the sources of odors. However, when these chemical substances are used, it is necessary to use them directly over a wide range of odor sources, so fragrances and deodorants themselves may become a new source of pollution, and they should be used in large quantities. Have difficulty.

As means for solving such problems, a deodorizing apparatus using ozone has been proposed, and is disclosed in, for example, the following Patent Documents 1 to 3. Patent Document 4 below discloses a deodorizer that combines ozone and a photocatalyst.

Patent Document 1 includes ozone gas generated in a closed space, deodorizing the odor in the space, and then an ozone gas decomposing device, and an air blowing unit that passes the ozone decomposing filter and external gas through the ozone decomposing filter. It describes a deodorizing apparatus equipped with an ozonolysis apparatus.

Patent Document 2 discloses a sterilization and deodorization apparatus that is small and portable using an ozone generation mechanism including a small discharge tube, a small timer, a small fan, and an inverter circuit. Are listed.

However, the techniques described in Patent Documents 1 and 2 generate ozone that is harmful to the human body at a high concentration for deodorization and sterilization, and therefore it is necessary to take measures against leakage of high concentration ozone. For this reason, care must be taken in handling the equipment, and a mechanism for ozone treatment is also required, resulting in complicated equipment.

In particular, Patent Documents 1 and 2 use high-concentration ozone, which causes problems such as ozone that is harmful to the human body leaking or intention to deodorize, but ozone ozone is leaking. In addition, since it is necessary to mix high-concentration ozone and the atmosphere to be deodorized, there are disadvantages such as requiring a circulation device for that purpose, making the device complicated, and limiting the atmosphere that can be deodorized. .

Patent Document 3 discloses a combination of a negative ion cluster (negative ion) generator and an ultraviolet irradiation device comprising a black light or an ultraviolet light emitting diode to decompose PCBs and other harmful substances, as well as tobacco, perfume, manure, etc. It describes an air cleaning device that can also deodorize other malodorous substances.

Patent Document 4 describes an air cleaner in which an ultraviolet irradiation device is combined with a thin photocatalyst having a deodorizing and disinfecting function.

However, the technique described in the patent literature has a problem that the irradiation range of ultraviolet rays is narrow and cannot be applied to deodorization in a wide space. Moreover, in the technique described in Patent Document 4, since it is necessary to pass air containing odors through a filter using a photocatalyst irradiated with ultraviolet rays, an air circulation device is required, and the deodorizing device is large and complicated. There is a problem.

  The present invention has been made in view of the above problems, and an object thereof is to provide a deodorizing apparatus that can reduce or eliminate the odor of a space without using an air circulation device and without generating high-concentration ozone. It is said.

The present inventor has noticed that the light of arc light has a deodorizing effect from the experience of using the arc light for many years, and has been experimenting on the deodorizing effect with the smell of industrial waste, the smell of chicken manure, and the like. The inventors have found that most odors can be reduced simply by irradiating the odorous space with the light of arc light, and have completed the present invention. This deodorizing effect of arc light is thought to be mainly due to the effect of ozone generated by the ultraviolet rays emitted by the arc light.

As a result of investigating the reduction of odor by irradiating the space filled with odor with strong ultraviolet light from arc light composed of xenon lamp with output of 5W-50kW, the bad odor from fish waste is It was confirmed that the human odor decreased to less than a fraction and the ammonia odor decreased to less than a fraction.

Thus, according to the present invention, the odor of the space can be greatly reduced by a simple operation of directly irradiating the space with the light of arc light. The concentration of ozone generated at the time of deodorization is the concentration generated when a normal arc light is turned on, and the concentration of the arc light in which ozone is suppressed is 0.05 ppm or less.

As described above, the deodorization method of the present invention enables the deodorization of a wide space while suppressing the generation amount of ozone harmful to the human body below the environmental standard. This is an important technology not only for inhabitants, but also for business people on the perpetrator side.

  Embodiments of a gas identification method according to the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an outline of an arrangement for realizing deodorization or deodorization by directly irradiating light including ultraviolet rays generated by arc light over a wide range of a deodorization target space.

In the figure, 1 shows the arrangement of a deodorizing device using an arc light composed of a xenon lamp. An arc light 1 with an output of 2 kW is on the upper side, and an odor source 3 that emits a bad odor such as garbage or waste is on the lower side. is there.

  The odor source emits the bad odor 4 toward the surroundings, and most of the odor is scattered upward by the wind after moving upward, causing bad odor pollution. The optical axis of the arc light is set so that ultraviolet light is irradiated to the space above the odor source where the bad odor generated from this odor source drifts.

  When the arc light is energized, the ultraviolet light 2 is applied to a space with a bad odor (from right to left in the figure). Ultraviolet rays generate ozone in the whole space where bad odors drift, making it possible to decompose bad odors.

  When arc lights were installed in a facility with the same arrangement as in Fig. 1 that handles industrial wastes such as fish arabes and leftovers, even workers who were used to odor work before installation had a bad odor for a long time. Although the work was difficult, after installation, it was dramatically improved so that even ordinary people who were not used to the bad smell could enter for a long time without great pain.

  FIG. 2 shows another embodiment for demonstrating the effects of the present invention. A main body cylinder 5 with an arc light 1 of 50 W output facing upward is set up vertically at the lower part, and an observer 7 can smell the in-cylinder in the upper part of the main body cylinder. Further, an odor source 3 such as a fish arabic that emits a bad odor 4 is arranged at the bottom of the branch cylinder 6 branched from the middle of the main cylinder. The ultraviolet ray 2 emitted when the arc light is turned on is irradiated toward the upper side of the main body cylinder, and the odor source is not irradiated with the ultraviolet ray.

  If the fish arabic is placed as an odor source without turning on the arc light, the odor emitted from the odor source enters the branch tube and into the main tube, and is detected as an odor by the observer at the top of the main tube. When the arc light is turned on in this state, ultraviolet light is irradiated to the space inside the main body cylinder. After a few minutes of irradiation, the bad smell in the cylinder decreased to such an extent that the observer could not detect the smell in the cylinder at the top of the main body cylinder.

  In this embodiment, the ultraviolet rays emitted from the arc light are only applied to a space with a bad odor, and the odor source is not directly applied. Nevertheless, the odor in the body cylinder has been reduced to such an extent that the observer cannot detect it. This indicates that the deodorizing apparatus based on the present invention has a great deodorizing effect by directly acting on the bad odor drifting in the space without directly acting on the odor source.

  FIG. 3 illustrates an example in which the present invention is applied to a pachinko hall. The space above the pachinko hall with the optical axis aligned horizontally so that the arc light 1 with 500 W output is attached to the upper surface of the frame 8 where the pachinko machines are lined up, and the ultraviolet rays 2 from the arc light are not irradiated to pachinko shop customers. Is efficiently irradiated. Before the installation of Arclight, the entire hall was filled with cigarette odors and the environment was unacceptable to customers who did not like tobacco odors. Realized.

  FIG. 4 shows changes in the odor level of pachinko halls in the embodiment shown in FIG. It shows that the odor level of the hall is drastically lowered after the operation of the device of the present invention, and the odor of the hall is almost completely disappeared in about 5 hours after the operation.

  In the embodiment shown in FIG. 1, FIG. 2, and FIG. 3, when the light source of the arc light 1 is changed from a xenon lamp to a halogen lamp that does not contain ultraviolet rays, the deodorizing effect as described in the above embodiment is obtained. It was not obtained. Therefore, the deodorizing effect of the present invention is considered to be due to ultraviolet rays generated by arc light.

  FIG. 5 shows the structure of the arc light used in the above embodiment. (A) is a front view, (b) is a side view. A light source for generating powerful light containing a large amount of ultraviolet light, a power supply circuit for stably lighting the light source, an outlet for supplying power to the power source, and condensing the light generated by the discharge tube in a desired range Or an optical system composed of a parabolic mirror 9 and a lens for converting the light into parallel rays so that the light can reach far.

A structure for storing a power supply for stably lighting the light source of the arc light and a case 10 are provided below the arc light, and the arc light is coupled to the structure by a universal joint 11 or the like. By changing the direction, light can be irradiated in a predetermined direction.

An optical system composed of a parabolic mirror and a lens system can change the distance to the arc light, and the arc light can be focused at an arbitrary point to be focused or parallel. It can be set to light rays or spread as the distance increases, and it can be deodorized by irradiating a desired range with arc light.

Preferably, an adjustable optical system capable of changing the reach distance and diffusion region of the arc light is provided, and light can be irradiated in accordance with the form of the deodorization target space. By making the light of the arc light into parallel rays with an optical system such as a lens or a reflector, it becomes possible to reach the light of the arc light to several kilometers away, and this method can also deodorize a very wide area. Become.

In addition, a power supply circuit that can adjust the output of the arc light according to the condition of the atmosphere to be deodorized is preferably provided. When the smell is strong, the amount of light is increased to increase the amount of ozone generated to quickly deodorize. When it is not strong, the amount of ozone is reduced to minimize the amount of ozone generated and minimize the impact on the human body.

  FIG. 6 shows the structure of an arc light source with an increased deodorizing effect. A spiral structural band 13 made of a metal such as titanium or a titanium alloy is installed on the light exit surface 12 of the arc light 1. This structure is a band-shaped or rod-shaped metal spiral, and the installation of this structure increases the deodorizing effect.

The spiral at this time does not need to be formed so as to draw a smooth curve, and can be a polygonal metal 13 as shown in FIG. 7, and even if such a polygonal spiral is used, The odor effect can be improved.
