Abstract

PROBLEM TO BE SOLVED: To miniaturize the dust collector and to promote purification of used water by allowing sterilized water obtained by jetting ozone into water in a tank arranged below a centrifugal separation part to permeate through a light-exciting catalyst filter before turning it into fine droplets by a rotary dividing disc through a nozzle and mixing them with dust containing gas introduced into the centrifugal separation part to discharge the gas as clean air from an air feeding cylinder. SOLUTION: Ozone generated by an ozonizer O is jetted into water in a tank T1 arranged below a centrifugal separation part 1 to sterilize it. The sterilized water is allowed to permeate through a light-exciting catalyst filter F' consisting of a light- exciting catalyst body 8 and an exciting light source 9 and is sprayed to a rotary dividing disc 3 through a nozzle (n). The generated fine droplets are scattered over the inside of the centrifugal separation part 1 to mix them with dust containing gas (a) introduced into the centrifugal separation part 1. The dust is caught by the fine droplets and is separated in the centrifugal separation part 1 and the remaining gas is discharged as clean air (a') from an air feeding cylinder 5. In this way, a dust collector that is miniaturized and has high effectivity is obtained, and by using the light-exciting catalyst filter F', purification capacity can be enhanced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector which collects dust in air and generates cleaning air, and a control method therefor.

[0002]

2. Description of the Related Art Conventionally, fine water droplets (mists) are generated,
An air purification method by bringing these fine water droplets into gas-liquid contact with air, and a negative ion generation method are known.
The water used for these is becoming increasingly contaminated with the passage of time and is a growth site for all kinds of bacteria. Therefore, if this air is released as it is, the bacteria will be scattered in the air. Therefore, after mixing the fine water droplets with the air, it is necessary to actively perform the air-water separation. The entire equipment becomes large due to the necessity of providing a cyclone separator),
In addition, the water used had to be frequently changed. In addition, in order to generate the above-mentioned fine water droplets, it is performed by injecting water from a nozzle, but in order to increase the efficiency of generating fine water droplets, it is necessary to increase the number of nozzles to a large number. It is necessary to increase the capacity of the injection pump (increase the size of the pump to increase the water pressure to generate fine water droplets). In addition to raising the water pressure in this way, it is necessary to make the nozzle opening narrow in order to increase the amount of generated fine water droplets,
As a result, there is a problem that the nozzle opening is easily clogged. Further, since the steam-water separation device is provided, unless the wind pressure is increased, the capacity for steam-water separation is reduced, and the fan for the steam-water separation is also enlarged (for example, Japanese Patent Publication No. 60-58368). Surface air feeding method, JP-A-5-302736; negative ion generation method and device, air purification method using negative ion generation and device, etc.). In addition to this, in this type of device, there is a disk-type mechanism that rotates a disk and sucks up water (Japanese Patent Publication No. 6-7870; negative ion air generator). The drawback is that it lacks purification ability because it is difficult to come out. As an apparatus for improving the above-described conventional technique, the present applicant 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. Hei 8-229334, and the like.

To promote the purification of used water by using a photo-excited catalyst filter, to cooperate with the mechanism and various air cleaning mechanisms or air conditioning mechanisms, and to provide a method of controlling the operation of the equipment.

Now, dust-containing gas (a) is passed through the air filter (F) through the air filter (F) [if necessary, several sheets of various performances are laminated], and the dust collector (f) is blown by the blower (f).
(X), while rotating the above-mentioned revolving water basin (3), the dust-containing gas (a) containing mist is mixed, and a cyclone phenomenon occurs in the centrifugal separator (1). At the same time, the dust in the dust-containing gas (a) is efficiently separated, taken out of the dust collector (X) as clean air (a '), and supplied to the room or the like. That is, this dust-containing gas (a) is sucked by the blower (f),
While moving around the inner wall inside the centrifugal separation part (1) as shown by the arrow, while moving downward, only dust is released,
It will be distributed from the central air supply cylinder (5). The direction of rotation of the rotary type water basin (3) is the same in the opposite direction as shown in the figure. Here, (6) is a diaphragm provided as needed,
(q) is a through-hole or an annular plate having irregularities on the inside, which is provided around the rotating water distribution plate (3).

As described above, the dust-containing gas (a) descends and rises along the inner wall of the centrifugal separation section (1) due to the inertial force, and clean air
