Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier provided with a sterilizing / deodorizing means. More specifically, the present invention relates to an air purifying apparatus provided with a sterilizing / deodorizing means in a medical facility such as a hospital or a food manufacturing facility.

[0002]

2. Description of the Related Art Various types of sterilizing apparatuses and methods for air purifying apparatuses have been proposed as follows.

(1) There is an air purifying device or a hospital room where a means for disinfecting and deodorizing air, such as an activated carbon layer, a photocatalytic layer, and ultraviolet rays, is provided (for example, JP-A-63-315).
No. 138).

(2) An electric precipitator inside the air purifier,
Some include an ozone generator and an ozone decomposition catalyst (see, for example, JP-A-2-48050).

(3) An ozone generator is installed inside the air purifier.
There is an anion generator provided with an anion generator and sterilization / deodorization means (for example, see Japanese Patent Application Laid-Open No. 4-260732).

[0006] (4) Some air purifiers are provided with an ultraviolet lamp and provided with sterilization and deodorization (for example, see Japanese Patent Application Laid-Open No. 7-239140).

(5) Some air purifiers include, in addition to an ozone generator and an ozone decomposition catalyst, a sheet filter or the like containing an antibacterial agent such as silver zeolite (see, for example, JP-A-6-323571). reference). (6) A sheet filter containing an antibacterial agent such as silver zeolite is applied or coated on the inside of an air purifier or on the surface of an inner wall, a fan, a filter, or the like (see, for example, JP-A-5-55176). ).

[0008]

The sterilization performed by the above-mentioned conventional air purifying apparatus is not sufficient for sterilization. Therefore, there is a possibility that the air in which the bacteria have propagated is sent to, for example, a hospital room or a food manufacturing room.

In the above-mentioned prior art, sterilization means is simply provided inside the air purifying device or in the flow path, and the sterilization treatment for airborne bacteria in a room or the like cannot be sufficiently performed effectively.

[0010] In particular, conventionally, since sterilization means is provided in the air conditioner, if it is desired to sterilize the room independently and intensively,
I couldn't do that.

In addition, because of the structure in which ozone is generated inside the air purifier for sterilization treatment and the ozone is decomposed immediately by the ozone decomposition catalyst, there is a limit in the spatial sterilization ability, and the air purification is limited. The size and capabilities of the aircraft were limited.

[0012] Further, in the conventional ultraviolet lamp, sterilization can be performed only in the irradiated portion or only within the reach of the irradiation. Therefore, the sterilization in the non-irradiated portion is incomplete. But the bactericidal effect was killed.

Furthermore, even if the antibacterial agent sheet is used for a long period of time, dust, oily smoke, etc. adhere to the surface of the coating film containing the antibacterial agent, thereby preventing direct contact with microorganisms or immediate approach. And the antibacterial effect is greatly reduced. Therefore, the antibacterial action is significantly impaired, and the sterilization performed by the above-described conventional air purifier has not been sufficiently sterilized. Therefore, there is a possibility that the air in which the bacteria have propagated is sent to, for example, a hospital room or a food manufacturing room.

An object of the present invention is to provide a device capable of sufficiently sterilizing and deodorizing a room or the like that solves the above problems. More specifically, depending on manned or unmanned, sterilization
An object of the present invention is to provide an apparatus and a method capable of performing deodorization in a necessary and sufficient manner.

[0015]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an ozone generator and an air purifying apparatus having a sterilizing / deodorizing means and an air blowing means as an ozone decomposing catalyst device, which are provided with an ozone corrosive or the like. In order to prevent this, an ozone fumigating section having an ozone fumigating path 16 and an air purifying section having an air purifying path 15 are provided. It is provided independently of the path 15.

Further, the present invention is an air purifying apparatus in which an ultraviolet lamp, a photocatalyst, and a photocatalyst exciting lamp are added to an ozone generator and an ozone decomposition catalyst device as sterilization / deodorization means, and provided with a blowing means.

In addition to strong ozone gas, an ultraviolet lamp, a photocatalyst, a lamp for exciting a photocatalyst, and an antibacterial coating or a photocatalytic coating can be provided in the air purifying apparatus. In addition to this, it is possible to perform a sufficient sterilizing / deodorizing action.

Further, it is provided with a sterilizing / deodorizing means and an air blowing means comprising an ultraviolet lamp, a photocatalyst exciting lamp, a photocatalyst, an ozone generator, an ozone decomposition catalyst device, and the like. In addition, an ozone generator and a blower for sterilization are provided in the ozone fumigation path 16.

At the time of ozone sterilization (fumigation), the fan, which is the blowing means on the upstream side of the ozone generator in the ozone fumigation path 16, is controlled by an inverter to reduce the number of revolutions, and to reduce the air volume and speed. The supply by increasing the ozone concentration is avoided while avoiding the consumption due to the decomposition of ozone.

Further, at the time of ozone deodorization, it is necessary to increase the rotation speed of the fan in the air cleaning passage 15 to increase the wind speed and air volume, increase the ozone decomposition amount, and supply detoxified air. Is also possible.

Ozone gas is used as the sterilizing / deodorizing means. Ozone is employed because it has not only strong sterilization but also a deodorizing effect.

When the chamber is unoccupied, the ozone fumigation path 16
After sterilizing and deodorizing the room with ozone gas-containing air from inside, maintain the state of the flow circulating again to the air purifier,
Ozone concentration is maintained at a predetermined value and for a predetermined time, and thereafter,
The ozone-containing air is made to pass through by operating an ozone decomposing device in the air cleaning path 15 to decompose and render ozone harmless.

When the room is manned, air from the room is guided into the air purifying path 15 in the air purifying device, and the ozone gas-containing air from the air purifying device is operated by the ozone decomposing device to pass therethrough. Ozone is decomposed and made harmless and sent to the room.

At the time of ozone deodorization, the air detoxified by the ozone decomposition catalyst can be further deodorized by an electric dust collector or a photocatalyst.

If a fan is provided on the downstream side of the ozone generator in the air purifying path 15 and on the upstream side in the ozone fumigating path 16, ozone generation or ozone generation can be reduced when used for ozone fumigating or air purifying. It can be more favorable for decomposition.

[0026]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 shows an embodiment of the present invention.

FIG. 1 shows an embodiment of the present invention. The air purifying device 1 has a casing made of an antibacterial steel plate in which an inorganic antibacterial agent or a photocatalyst is made into a paint and baked and coated on the inner and outer surfaces.
A housing can be configured.

On the inner surface of these air purifiers,
An antibacterial agent can be contained in a coating film and held.
In this case, the antibacterial agent is contained in a paint or the like, and is applied by baking, roller coating, spraying, or the like.

As the antibacterial agent, an inorganic material such as silver, zinc oxide or copper is used alone or in combination. Due to the action of the antibacterial agent, the growth of microorganisms such as bacteria and mold on or near the surface of the coating film or the like is suppressed, and can be reduced and sterilized.

As shown in FIG. 2, inside the air purifying apparatus 1, an antimicrobial medium-performance filter 2, an ultraviolet lamp 3, a photocatalyst exciting lamp 4, a photocatalyst A filter 5, a deodorizing ozone generator 7, an ozone decomposition catalyst device 8, an electric dust collector 9 or a photocatalyst 10, an air cleaning fan 11, an ozone concentration sensor 13, and the like are provided. In addition, the ozone fumigation path 16 of the ozone fumigation section
Inside, an ozone generator 6 for sterilization, a fan 12 for ozone fumigation, and the like are provided.

The ozone generator is an ozone generator 6 for sterilization.
And an ozone generator 7 for deodorization. Sterilization is for the purpose of sterilization, and deodorization is for the purpose of reducing the amount of ozone generated.

The fans 11 and 12 can be provided at both the upstream and downstream of the path. If the fan 11 is provided on the downstream side of the air cleaning path 15 of the air cleaning apparatus 1, it becomes a suction type. Ozone gas is more intrusive than pressurized
No leakage to the outside. In addition, if the fan 12 is provided in the ozone fumigation path 16, it becomes a push-in type, but in this case, it is possible to perform processing so that ozone is not destroyed as described later. Although FIG. 1 shows a centrifugal fan, it is needless to say that a lateral flow fan or a sirocco fan can be employed.

The rotation speed of the fan 12, which is a blowing means in the ozone fumigation path 16, can be arbitrarily varied by inverter control. The amount of ozone generation can be adjusted in an optimal operating state according to conditions, for example, the size of the living room, temperature and humidity. That is, the fan 12
This is because the amount of ozone decomposed can be adjusted by the number of rotations. If it is provided on the downstream side, the ozone generation efficiency is affected by the ozone generated by the adsorption of the fan to the fan and the ozone decomposition by the rotating action. Here, ozone fumigation refers to a case where the ozone concentration is high and sterilization and deodorization are performed directly indoors without any person.

When deodorizing ozone in the air purifying path 15, the number of rotations of the fan 11 is increased to increase the wind speed and air volume, and the ozone decomposition amount is increased to supply detoxified air. It is also possible. Here, the time of ozone deodorization means that sterilization is performed in the air purifying apparatus 1, but ozone is decomposed by the ozone decomposition catalyst in the apparatus 1 and deodorized by the deodorizing action at this time. This is the case.

When using ozone for sterilization and deodorization,
For sterilization, an ozone generator with an ozone generation amount of several hundred to several thousand mg / h is used.
By using an ozone generator of about h, it is possible to effectively use ozone, to assure safety during deodorization, and to prolong the life of the ozone decomposition catalyst. The output of the ozone generator can be adjusted to adjust the amount of ozone generated.

An electric precipitator 9 or a photocatalyst 10 can be provided downstream of the ozone decomposition catalyst 8. When the electric dust collector 9 is used, the residual ozone odor is physically decomposed electrically. At this time, negative ions are obtained, and air in a favorable environment for the human body can be supplied. When a photocatalyst is used, the residual ozone odor is decomposed by the oxidation-reduction action.

Since ozone has a low reactivity to ammonia, for example, it is conceivable to place an activated carbon filter on the downstream side of the ozone decomposition catalyst. However, activated carbon cannot adsorb substances having a small molecular weight and deodorizes. The function has a lifetime problem mainly due to the adsorption action.

If, for example, a photocatalyst is used instead of the activated carbon filter, deodorization and sterilization can be performed over a wide range not only of ammonia but also of acetaldehyde, trimethylamine, acetic acid, methyl mercaptan, styrene, hydrogen sulfide, nitrogen oxides and the like. Become. The deodorizing function has a long life, mainly due to the oxidation-reduction action, and has a bactericidal action as well as a deodorizing action. Activated carbon itself does not have a bactericidal effect, so it is likely to become a hotbed of bacteria, but photocatalysts do not.

The characteristics of the system for sterilizing and deodorizing pathogenic bacteria will be described in detail below. In the air purifying apparatus 1, as a component of the sterilizing / deodorizing system, for the non-treated air, the inside of the air purifying apparatus 1 is provided as an air purifying unit in the air purifying path 15, and an antibacterial medium-performance filter. 2, ultraviolet lamp 3, photocatalyst excitation pump 4, photocatalyst filter 5, ozone generator for deodorization 7, ozone decomposition catalyst device 8, electric dust collector 9
Alternatively, a photocatalyst 10, an air cleaning fan 11, an ozone sensor 13, and the like are provided. Also, as an ozone fumigation section, an ozone generator 6 for sterilization, a fan 12 for ozone fumigation, and the like are provided in an ozone fumigation path 16. . In the drawing, an embodiment in which an ozone fumigation path 16 is provided in parallel adjacent to the air cleaning path 15 is shown.

Although FIG. 2A shows a long lamp-type ozone generator 6 in which no NOx is generated, other discharge-type ozone generators 6 as shown in FIG. It can be carried out. An ozone generator power supply 60 is provided for that purpose. In this case, the shape can be further reduced, the device can be made compact, and the size can be reduced. Further, the amount of ozone generation can be changed to some extent by adjusting the voltage.

Further, in the present invention, the air cleaning device 1 is provided in two systems, one for air cleaning and the other for ozone fumigation.
When the ozone generator 6 is installed in the ozone fumigation path 16, it is possible to provide the ozone generator 6 with sufficient margin along the flow path, even if the ozone generator 6 has a long capacity. Become.

First, an ultraviolet lamp 3 having a wavelength of 254 nm
When irradiated by this, the air-borne bacteria contained in the unprocessed air may damage the DNA of the bacteria due to the heat energy of the ultraviolet lamp 3 and, as a result, form a self-proliferating function by the formation of teaming dimers. Lower.

For airborne bacteria contained in untreated air, a combination of a specific wavelength of ultraviolet light and a photocatalyst is effective. That is, a characteristic of the titanium oxide photocatalyst system is that a reaction occurs when its surface comes into contact with water. Due to its adsorptive properties, the reaction occurs even if it comes into contact with air unless it is completely dry.

For the titanium oxide photocatalyst, preferably, ultraviolet light having a wavelength range of 315 to 400 nm is suitable for exciting the photocatalyst. When an ultraviolet lamp 4 having a wavelength of about 400 nm hits the surface of titanium oxide, a strong oxidation potential of 3 V is generated, and water is decomposed to generate active oxygen. This is an oxidation potential higher than that of chlorine, hydrogen peroxide, ozone, or the like, and is such that almost everything can be decomposed and oxidized.

Therefore, if a photocatalyst excitation lamp 4 (also referred to as a black light lamp), which is a kind of an ultraviolet lamp, is provided, the irradiation causes the light to generate an oxidation-reduction potential of 3 V.
The titanium oxide photocatalyst (anatase type) photocatalyst filter 5 is more activated, active oxygen is generated, and bacterial spores and verotoxin are destroyed.

On the other hand, the former ultraviolet lamp 3 without a photocatalyst may be an ordinary germicidal lamp having a wavelength of 100 to 280 nm. This is because the photocatalyst has an effect of causing the effect, but is low. As described above, by irradiating the photocatalyst by irradiating ordinary ultraviolet rays in the former stage and changing the wavelength of the ultraviolet rays, the sterilizing effect can be further enhanced.

In the case where the ultraviolet irradiation in the former stage is reversed,
This is because active oxidative oxygen changes the surface DNA of the spore and a part of the DNA inside the spore, suppresses the production of TDHT in the spore during irradiation with ultraviolet light, and reduces the bactericidal effect because some bacteria cannot be completely sterilized.

Thereafter, the spores of DNA-deformed bacteria are damaged again by ozone gas having a redox potential of 2.8 V generated by the ozone generator 6 for sterilization or the ozone generator 7 for deodorization, thereby causing a lysis phenomenon. Stop bacterial growth.

As described above, if the ultraviolet lamp 3 and the photocatalyst are used in addition to the ozone gas, the germicidal action can be complemented by the mutual advantage. That is, the ozone gas can be filled and sterilized even outside the range where ultraviolet light cannot reach, and when ultraviolet light or a photocatalyst is used, the ozone gas easily damages the spores of cells, and a further sterilizing effect can be obtained.

When air is supplied to the room, ozone is decomposed by the ozone decomposition catalyst device 8 using the ozone generator 7 for deodorization, and 0.1 ppm or less of ozonized air is supplied. The ozonolysis catalyst device 8 is made of manganese dioxide, so that ozonolysis can be performed efficiently even in a low temperature range, and active oxygen generated during ozonolysis can be expected to have a sterilizing / deodorizing effect.

A heater (not shown) may be provided in order to avoid a decrease in the effect due to a water film, dirt or the like generated on the surface of the ozone decomposition catalyst device 8. The heater has hot air heated to about 50 degrees and has a desorption / regeneration function.

In the air purifying apparatus 1, an antibacterial agent which can always be expected to be effective can be used for the components of the apparatus or the casing steel plate of the apparatus. As the antibacterial agent, a safe and highly heat-resistant inorganic antibacterial agent is used.

The inorganic antibacterial agent has a broad antibacterial spectrum and has an effect of not causing resistant bacteria. As a method of maximizing the disinfecting and deodorizing effect, when an antibacterial agent is mixed with a paint, the dispersibility is improved, and the antibacterial effect can be improved by floating on the surface.

When the inorganic antimicrobial agent is mixed into the paint, the dispersion is eliminated by coagulating the antimicrobial agent by mixing and dispersing it sufficiently in a solvent or the like in order to improve the dispersibility. And

Bacteria that have come into contact with the antibacterial agent are destroyed by metal ions (eg, silver, zinc, copper ions, etc.), cause lysis, and die. The air purifying device 1 has a function of mainly sterilizing and deodorizing falling adherent bacteria. With the above configuration, it is possible to systematically sterilize and deodorize.

When a coating film containing an antibacterial agent is applied to the inside of the air purifying device 1, the growth of bacteria and the like is usually suppressed inside the air purifying device 1, and sterilization is always performed regardless of whether ozone gas is generated or not. Be affected.

As described above, the antibacterial agent can be expected to have a sterilizing effect not only at the time of gas generation like ozone gas but also at all times. When used in combination with ozone gas, bacteria can be further exterminated. Can reduce the sterilization time and cost.

In carrying out the sterilization and deodorization, the following treatment methods are generally performed in a room or an air purifying apparatus when manned or unmanned. (1) Sterilization and deodorization of uninhabited rooms (2) Sterilization and deodorization of uninhabited rooms

The sterilization and deodorization of the room when no one is working will be described.

When there is no person in the room, such as at night,
Introduce ozone into the room and fumigate the room with ozone. That is,
Maintain a high ozone concentration for a certain period of time. This makes it possible to strongly sterilize the interior of the room.

More specifically, when there is no person inside the room, such as at night, that is, when the person is unmanned, the ozone generator 6 for sterilizing the ozone fumigating section is operated, and the ozone fumigating fan 12 is turned on.
, Only the ozone-containing air is introduced into the chamber.

In this case, as described above, the number of revolutions of the fan 12 as the blowing means can be arbitrarily varied by inverter control, and an ozone generator suitable for the environmental conditions can be provided. Here, the ozone fumigation time means that the ozone concentration is high, that is, a case where sterilization is performed directly indoors without any person.

While maintaining this state, the room is sterilized by applying an ozone concentration for a certain period of time.

After that, the operation of the air cleaning fan 11 of the air cleaning apparatus 1 is restarted. The untreated residual ozone air is sucked into the ozone decomposition catalyst device 8. Thus, the air inside the chamber circulates, and ozone is decomposed by the action of the ozone decomposition catalyst device 8. Hereinafter, the operation of the ozone decomposition catalyst device after sterilization and deodorization is performed in the same manner.

Thus, the ozone concentration in the room air inside the room is reduced and reaches below the human safety limit. At that time, the operation of the air cleaning device 1 is stopped.

Next, the supply of the sterilized and deodorized circulating air into the room when a man is present will be described.

Even when a person is always in a room where the person is always present, the air is led into the air cleaning path 15 of the air purifying apparatus 1, and the ozone generated by the ozone generator 7 is passed through the ozone decomposition catalytic device 8. By the decomposing action, it can perform a bactericidal action and at the same time a deodorizing action.

The sterilized and deodorized air from the air cleaning device 1 maximizes the number of revolutions of the fan 11 and increases the wind speed and air volume, thereby forcing the residual ozone air by the flow of the high pressure and strong wind in the fan 11. It can be naturally decomposed naturally, and it is harmless and odorless before supplying air to the room.

In addition to naturally decomposing the remaining ozone gas by the high-speed rotation of the fan 11, if the electric precipitator 9 or the photocatalyst 10 is used in combination, the synergistic effect of the fan 11 on the human body causes
It can supply safer air.

When the ozonolysis catalyst device 8 is operated and the air purifying device 1 is operated in the air purifying path 15 of the air purifying device 1, the air passing through the device 1 is subjected to a sterilizing action.

The sterilized air is supplied to the room through a duct or the like. By performing such air circulation, the sterilizing action in the indoor air is continuously performed. Ozone from the ozone generator 7 is naturally decomposed and made harmless by the action of the ozone decomposition catalyst device 8.

As an antibacterial means, dust and oily smoke attached to an antibacterial sheet or a portion coated with paint can be removed by circulating ozone gas or simply flowing circulating air.

In the air purifying apparatus 1, the concentration of ozone is constantly controlled by the ozone sensor 13 at the fan outlet, and when the ozone sensor 13 detects a value equal to or more than the allowable value, the ozone generator 7 is immediately turned on. Is stopped so that it becomes equal to or less than the allowable value.

As described above, according to the present invention, the circulated air can be sent for sterilization and deodorization as required, or when sterilized and deodorized when manned.

By providing the above configuration, the present invention can achieve the expected operation.

[0076]

The air purifying apparatus according to the present invention comprises an ozone generator, a disinfecting / deodorizing means and an air blowing means as an ozone decomposing catalyst apparatus. And the air purifying section having the air purifying path 15 so that the processing of sterilization and deodorization of the air in the room and the associated flow path and the like can be sufficiently performed according to the manned or unmanned state as necessary. It is possible to perform sterilization and deodorization in a necessary and sufficient manner in response to manned or unmanned use.

As the sterilizing / deodorizing means is provided with an ozone generator and an ozone decomposition catalyst device, not only the strong sterilizing power of ozone gas but also a deodorizing effect can be sufficiently expected.

Conventionally, when there is a person, that is, when there is a man,
Since sterilization and deodorization were not possible,
Although it was extremely limited at night and the like, even when manned, it is now possible to sufficiently perform sterilization and deodorization of each room, the air cleaning device, and the associated flow passages, etc., as needed.

In the above-mentioned prior art, sterilization means is simply provided inside the air conditioner or in the flow passage, and since it passes through the room temporarily, it is difficult to completely sterilize it. However, since the full-scale sterilization means was effectively arranged, it was possible to concentrate and continuously perform. In particular, according to the present invention, sterilization and deodorization can be surely performed intensively, especially in a room.

Further, in the conventional ultraviolet lamp, sterilization can be performed only in the irradiated portion or only within the range of irradiation, and sterilization in the non-irradiated portion is incomplete. Unavoidable, the bactericidal effect has been destroyed, but ozone gas is out of reach of ultraviolet rays,
It could be filled and sterilized, and when used in combination with ozone gas, a further effect was obtained.

Further, if antibacterial means is provided in the air purifying device, in addition to the strong sterilizing power of ozone gas, a sterilizing action can be expected at all times regardless of whether or not ozone gas is generated. If used together, it is possible to exterminate bacteria more strongly, and it is possible to reduce the sterilization time and cost by using only ozone gas.

In addition to the ozone gas, if an ultraviolet lamp and a photocatalyst are used and normal ultraviolet irradiation is performed in the first stage to irradiate ultraviolet light to generate active oxygen of the photocatalyst, the ozone gas in the next stage is also reduced. In addition, the bactericidal effect can be further improved.

Further, conventionally, even if an antibacterial agent sheet is used for a long period of time, dust and oily smoke adhere to the surface of the coating film containing the antibacterial agent, but ozone gas or circulating air is circulated in the air cleaning device. Therefore, adhesion of dust, oily smoke, and the like is prevented.

Further, by separately setting the ozone fumigation path and the air cleaning path, it is possible to minimize the deterioration of the equipment due to corrosion during the ozone fumigation.
This facilitates maintenance and maintenance.

In particular, in the ozone fumigation route, no equipment that may be affected by corrosion or the like is provided downstream of the ozone generator, so that an ozone generator that generates a large amount of ozone should be used. In addition, since the two ozone generators are used, there is sufficient space for installing the ozone generator, so that the capacity at the time of fumigation of ozone can be greatly improved.

In the air purifying route, the ozone concentration is in the ozone fumigation route by virtue of the strong sterilization and deodorizing action of the active oxygen generated at the time of ozone decomposition because the ozonolysis catalyst is provided on the downstream side. Fewer than required. This is even more so because the effect due to the photocatalytic action is added.

In the present invention, since the two systems are separately provided, the height of the center of gravity of the apparatus can be made lower, which is preferable in terms of stability. For this reason, it became possible to freely move to each room by attaching a movable caster.

When a fan is provided on the downstream side of the ozone generator in the air purification path 15 and on the upstream side in the ozone fumigation path 16, ozone is generated when used for ozone fumigation or air purification. Or more favorable for decomposition.
