DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purification / conditioning method applied to a humidifier for supplying fine water droplets, a negative ion generator, a dust collector for mixing fine water droplets with air, and a mechanism thereof.

[0002]

2. Description of the Related Art Conventionally, fine water droplets (mists) are generated,
A method of purifying air by separating these fine water droplets from air and gas-liquid contact and separating water and water and generating negative ions is also known.
Over time, contamination progresses and can be a bacterial growth ground. Therefore, the water used must be frequently changed. (For example, Japanese Patent Publication No. 60-5836
No. 8; surface air feeding method, JP-A-5-302736; negative ion generation method and device, and air purification method and device using negative ion generation can be mentioned). In this way, depending on the method and means of gas-liquid contact and gas-water separation, dust, bacteria, and chemical substances (gas) in the air
And, it is possible to remove the smell, but in the water used circulating here, these substances remain, and it is inevitable that dirt and germs propagate by taking in,
There is a risk that such dirt and bacteria themselves will be released.

[0003] In order to suppress the propagation of various germs, some use an antibacterial material (that has been subjected to antibacterial processing), but this is not effective against all bacteria, However, there is a concern that it may become resistant later. Also, if dirt or resistant bacteria adhere to the surface of the antibacterial material, the function of the antibacterial material becomes invalid. On the other hand, a germicidal lamp is provided in the flow path of the used water, and there is also a germicidal device that sterilizes the passing water. For example, bacteria grow in tanks, attached devices, and the like. Chemicals that are hardly soluble in water (gas)
And the smell is essentially inaudible. As an improvement over the above conventional technology, the present applicant has previously filed Japanese Patent Application No. 6-293992;
No. 46 "Air cleaning method and air cleaning machine", Japanese Patent Application No. 7-
No. 63409; Japanese Patent Application Laid-Open No. H8-229334 filed an invention such as "Dust Collector" and Japanese Patent Application No. 9-187833 proposes an invention of "Dust Collector and Control Method Thereof".

[0004]

The present invention is a further improvement of each of the above-mentioned inventions of the present applicant, which is based on the air drawn into the fine water droplet generating mechanism or the air generated there. An object of the present invention is to promote air conditioning by adding a means for passing a mixture with fine water droplets through a photoexcited catalyst filter, a heater, and the like to perform air purification.

[0005]

A photoexcited catalyst filter and / or a heater are provided before or after the fine water droplet generating mechanism so that air or air and fine water before and after the mixture of air and fine water droplets are generated. An air purification / harmony method characterized by allowing a mixture with water droplets to pass therethrough, and a photoexcited catalyst filter or heater at the front or rear of the fine water droplet generation mechanism, respectively.
Alternatively, an air purifying mechanism having both of them is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air purifying mechanism according to the present invention will be described with reference to FIG. In the air purification mechanism (X),
The pre-filter (1), high-performance filter (2), fan
(3), fine water droplet generation mechanism (4), photoexcited catalyst filter
(5) [A structure to which a photoexcited catalytic substance (for example, titanium oxide or the like) is added, and has functions such as antibacterial, sterilization, decomposition of chemical substances, and deodorization]. First, untreated air (a) is pre-filter (1), high-performance filter (2)
After passing through the fine water droplet generation mechanism (4), it passes through or is brought into contact with the photoexcited catalyst filter (5), and is subjected to the cleaning treatment to the outside of the air purification system (X) as clean air (a '). Sent out.

Here, as the fine water droplet generating mechanism (4),
For example, in a mechanism as a humidifier, it generates fine water droplets, and in a so-called negative ion generator or dust collector, a more aggressive gas-liquid mixing section and a gas-liquid separation section are additionally provided. is there. It is desirable to install an excitation lamp (L) near the photoexcited catalyst filter (5) to regenerate and promote the catalytic reaction.
(X) Depending on the overall configuration, this is not the only requirement if fluorescent light or sunlight from another location is applied to the photoexcited catalyst filter (5), and it may not be provided. The photoexcited catalyst filter (5) may be provided in plural as necessary, and may be provided in plural places.

FIG. 2 shows an air purifying mechanism (X ′) according to another embodiment in which a heater (6) is provided between the fine water droplet generating mechanism (4) and the photo-excited catalyst filter (5). The air from the fine water droplet generation mechanism (4) is sterilized by a heater (6), incinerated, and then purified by a photo-excited catalyst filter (5). Further, the excitation lamp has a configuration in which a UV tube (L ') and a reflector (7) are provided in front of the UV tube (L'). Reflector (7) is a UV tube
(L ') light is efficiently radiated to the photoexcited catalyst filter (5), and the radiant heat from the heater (6)
(L '). Examples of the heater (6) include a honeycomb-shaped ceramic heater.

The heater (6) performs sterilization, incineration of house dust, incineration and decomposition of chemical substances, and the like. Further, since the above-mentioned negative ions are hardly reduced by heat, they are suitable for combination with a fine water droplet generating mechanism. As described above, by providing the heater (6) between the fine water droplet generating mechanism (4) and the photoexcited catalyst filter (5), the release of bacteria and the like can be prevented. Note that a configuration in which only the heater (6) is provided alone may be employed. Further, the photoexcited catalyst filter (5) and the heater (6) may be provided individually or in combination at the stage preceding the fine water droplet generating mechanism (4). As a result, invasion of bacteria and the like can be prevented first. A plurality of photoexcited catalyst filters (5) and heaters (6) may be provided if necessary, and may be provided at a plurality of locations. In addition, in the mechanisms of the air purification mechanisms (X) and (X ') of each embodiment, other means that have an effect on sterilization can be appropriately added.

[0010]

A wide range of gases [ammonia, acetaldehyde, acetic acid, trimethylamine, methyl mercaptan, hydrogen sulfide, styrene, methyl sulfide, dimethyl disulfide, isovaleric acid, NOx]
(Nitrogen oxides) and others], and by installing them in the air purification mechanisms (X) and (X '), the deodorizing performance can be enhanced. This photo-excited catalyst filter (5) can regenerate its ability by irradiating light,
It can maintain the cleaning ability for a long time, has excellent antibacterial performance, and can prevent re-scattering of bacteria and the like from the photoexcited catalyst filter (5). In particular, the air that has passed through the fine water droplet generation mechanism (4) has high humidity, which may cause the growth of bacteria that prefer moisture, but the photoexcited catalyst filter (5) itself has the excellent antibacterial performance as described above. It is characterized by no significant deterioration in deodorizing ability even under high humidity.

Therefore, it is a suitable measure to dispose the photoexcited catalyst filter (5) in the air purifying mechanism having the fine water droplet generating mechanism (4), and it is very effective.
It provides an excellent purification effect. An excitation lamp is not always necessary. For example, a photo-excited catalyst filter may be installed at the air intake (intake port) or air take-out port (exhaust port), or external light may be provided near the photo-excited catalyst filter. Even if a transparent material (window material, optical fiber material, etc.) is placed, or if this photoexcited catalyst filter is placed deep inside the entire mechanism, an appropriate opening or a means for taking in light (for example, an optical fiber Through the light from outside, etc.)
However, it is regenerated by light outside the mechanism, and a deodorizing function can be efficiently and inexpensively added.
