Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector that collects dust in the air to generate cleaning air and a control method thereof.

[0002]

2. Description of the Related Art Conventionally, fine water droplets (mist) are generated,
An air purification method by bringing this fine water droplet into contact with air in a gas-liquid manner, and a negative ion generation method are known.
The water used for these purposes has become contaminated over time and has become a breeding ground for all bacteria. Therefore, if this air is released as it is, the bacteria will be scattered in the air, so it is necessary to actively perform air-water separation after the mixing of the fine water droplets and air. Since it is necessary to install a cyclone separator, the entire equipment becomes large,
Moreover, it was necessary to frequently change the water used. Further, in order to generate the fine water droplets, it is carried out by spraying water from the nozzle, but in order to increase the efficiency of the generation of fine water droplets, it is necessary to increase the number of nozzles to a large number, and therefore the water used It is necessary to increase the capacity of the injection pump (enlargement of the pump for increasing the water pressure to generate fine water droplets). In this way, in addition to increasing the water pressure, it is necessary to make the nozzle mouth narrow in order to increase the amount of fine water droplets generated,
As a result, there is a problem that the nozzle port is easily clogged. Further, since the air-water separator is provided, the capacity for air-water separation decreases unless the wind pressure is increased, and the fan for that purpose also becomes large (for example, Japanese Patent Publication No. 60-58368). A surface air supply method, JP-A-5-302736; a negative ion generation method and its device, an air purification method utilizing negative ion generation and its device, etc.). In addition to this, in this type of device, there is a disc-type mechanism that rotates a disc to suck up water (Japanese Patent Publication No. 6-7870; negative ion air generator), but such a mechanism produces fine water droplets. The drawback is that it lacks purification ability because it is hard to come out. As an apparatus for improving the above-mentioned conventional technique, the applicant of the present application has previously filed Japanese Patent Application No. 6-293992;
No. 6, “Air Cleaning Method and Air Cleaning Machine”, Japanese Patent Application No. 7-6
No. 3409; Japanese Patent Application Laid-Open No. 8-229334, “Dust collector” and other inventions have been filed.

Now, the dust-containing gas (a) is introduced from the entrance (4), through the air filter (F) [where necessary, several sheets with various performances are stacked], and then by the blower (f).
By taking in the inside of (X), while rotating the rotating water diversion board (3), the dust-containing gas (a) containing mist is mixed and the cyclone phenomenon is generated in the centrifugal separation section (1). At the same time, it is increased to efficiently separate the dust in the dust-containing gas (a), and is taken out of the dust collector (X) as clean air (a ') to be supplied and distributed indoors. That is, this dust-containing gas (a) is sucked by the blower (f),
Around the inner wall of the centrifuge (1), while moving circularly as shown by the arrow, while moving downward, only dust is released,
It will be delivered from the central sending cylinder (5). The rotation direction of the rotation type water diversion board (3) is the same as the direction opposite to that shown in the drawing. Here, (6) is a partition plate provided as necessary,

As described above, the dust-containing gas (a) is inertial force and descends and rises along the inner wall of the centrifugal separator (1) to clean air.
As (a ') enters the sending cylinder (5) and is discharged to the outside of the dust collector (X), the dust captured during this period is used in the tank (T ₁ ) installed below. It comes into contact with water (W), and this used water (W) is initially pumped from the cartridge type sub-tank (T ₂ ) prepared in advance by the pump (7) to the photoexcited catalyst filter (F ′) [photoexcited catalyst (8) Excitation Light Source (9)
Consists of two parts, one is in the nozzle (n) direction and the other is in the tank (2) for circulation. Ie tank
The used water (W) aerated by the ozone fumes from the ozone mixer (m) of the ozone generator (O) in (T ₁ ) passes through the photoexcited catalyst-added filter (F ') and the nozzle tube (c). Further, it is sprayed on the rotating water diversion board (3) and again becomes fine water droplets and enters the centrifugal separation section (1) and circulates. Note that (J) is the water used in the tank (T ₁ ).

It is to prevent the blowing up of. It should be noted that this is particularly effective for the vertically long configuration of the centrifugal separation unit (1).
Also here, harmful nitrogen oxides generated during ozone generation are trapped in the used water (W), and the amount released to the air distribution can be reduced. Further, it is also effective that the nitrogen oxide can be decomposed by the photoexcited catalyst body (8) in combination with the photoexcited catalyst filter (F ′) described above. (10) is a drain discharge part.

Next, the details of the photoexcited catalytic filter (F ′) will be described. As shown in FIG. 3a, the photoexcited catalytic filter (F ') is required for the photoexcited catalytic substance [for example, titanium oxide] mainly for the ultraviolet light [fluorescent lamp is acceptable] as the excitation light source (9) in the inside thereof. Ceramic, according to
