Description

[0001] The present invention relates to a dust clearing device using a filtration plate,

The present invention relates to a device for removing fine dust and foreign matter contained in indoor air, and more particularly to a device for removing fine dust and foreign substances contained in indoor air, more specifically, In the filtration plate means, the spray particles and the contaminated air come together, and the fine dust is purified from the filtration plate. Then, the clean air is supplied to the room, and the separated fine dust is removed to the cleanser (water tank or water tank) To a fine dust removing apparatus using a filtration plate that can remove various fine dusts in air flowing into a room to create a pleasant indoor environment.

Generally, the outside air supplied to the room contains yellow dust, fine dust, various noxious gas and virus. In order to remove pollution such as yellow dust and fine dust, an air purifier is installed in the room.

These air cleaners are divided into two types, dry and wet, and the dry type is divided into two types, electric dust collection and filter filtration. Here, the electric dust collection type has an advantage that it is not necessary to replace the filter because there is no filter, but if the dust collects on the electric dust collection panel, the cleaning ability is deteriorated and the dust removing ability is weak.

The filter filtration equation can be evaluated as optimal for removing dust and dirt due to its excellent purification ability because various fine particles are filtered by the filter while air flows through the filter. However, since it is necessary to replace the filter periodically, it is troublesome, There is a disadvantage that a replacement cost is incurred.

In addition, the wet air cleaner has the advantage that the inhaled air is brought into contact with water so that harmful substances are adsorbed and removed on the water, there is no need to replace the filter, the noise is small, and the humidifier function can be performed.

As such a conventional apparatus, a wet air purifier of Patent Registration No. 10-0929140 is known.

The wet air cleaner of the related art includes a driving unit that provides rotational power, a suction unit that moves the outer air downward by being pivotally connected to the driving unit, and a rotary shaft connected to the suction unit, And a spray hole for spraying the water moved upward along the flow path to the outside, and a rotary spray part provided below the rotary spray part for rotating the rotary spray part And a liquid supply device for supplying the liquid additive to the inside of the case part. The present invention relates to a liquid supply device for supplying a liquid additive to an inside of a case.

Another conventional device is known as a " water washing air purifier " of Registration Utility Model No. 0-0309268.

Conventionally, the water cleaning air purifier maximizes the contact surface between polluted air and water to adsorb and clean harmful substances, which are pollutants in the air, in particulate state and gaseous state into water having a high adsorption capacity, In the cleaner, the contaminated air sucked first is showered with water sprayed from a shower passage, then flows into the washer, which is a component of the purifier, together with the sprayed water, and is sprayed in the circumferential direction under the water surface by the spray nozzle The water and air are mixed and rotated. After passing through the narrow space between the outer wall and the inner wall of the washer, the air and the water are separated and the air is returned to the outside and the water is recovered to the water tank. The dust and harmful substances in the air are largely adsorbed on and removed from the water, the air is purified cleanly, The dry air is humidified, and the humid air is dehumidified to provide a pleasant indoor air.

Further, in the prior art, "fine dust removing device" of the registered patent application No. 10-1628076 filed by the present applicant is known.

The "fine dust removing device" of the above-mentioned Japanese Patent Application No. 10-1628076 filed by the present applicant and known in the art includes a blowing means for introducing outside air, a spraying means for spraying water by pumping water, And a cleaning means for cleaning and discharging the dust. The contaminated air guided by the air blowing means is sprayed on the spray particles sprayed by the spray means and is primarily cleaned and cleaned. The clean air is supplied to the room after the fine dust is purified in the water, and the separated fine dust is removed to the clean water tank (water tank) together with the washing water to remove the fine dust.

An operation procedure for removing fine dust introduced into the room using the fine dust removing apparatus 100 using the filter plate having the above-described structure will be described below.

First, as shown in FIG. 5, water is stored in the water storage tank 110.

The spraying means 120 and the air suction means 140 are operated. These are operated by a controller (not shown).

Then, the foreign air is sucked into the duct portion 141 by the air blowing means 142 of the air suction means 140, and various foreign substances are filtered by the foreign matter filter 143.

The air introduced into the body member 130 through the duct portion 141 is guided by the lower bracket 133 and the bent portion 133a and is guided to the bottom side of the body member 130 And then rise again. At this time, air is lowered to the bottom side of the body member 130, and foreign substances or other fine dusts contained in the air are buried on the surface of the water.

The water supplied to the pump 121 is supplied to the filter member 114a after foreign matter or fine dust is filtered.

The air upwardly rising from the bottom side of the body member 130 is mixed with the atomized particles injected from the injection nozzle 122, and the fine particles in the air fall on the atomized particles to fall on the water surface, Removed.

Fine dust that can not be removed by the sprayed particles of the injection nozzle 122 can be removed from the plate 152 on the inner side of the filtration plate means 150. That is, when the spray particles and air pass through the plate 152, fine dust adheres to the plate surface, and the spray particles fall downward to collect in the space A and escape to the water outlet 162a, .

At the same time, air escapes from the plate 152 outside the filtration plate means 150 and is discharged to the room through the air discharge port 181. In this process, the remaining fine dust adheres to the surface of the plate 152 and is finally removed. Therefore, after the filter plate unit 150 is used a number of times, the filter plate unit 150 is separated to clean fine dust adhering to the surface of the plate 152, and then assembled again.

As described above, fine dust can be easily removed by the plate 152 on the inner side of the filter plate unit 150.

Therefore, the present invention can completely remove the fine dust contained in the air by the spraying means 120 and the filtration plate means 150.

The structure of the injection nozzle 122 is not limited to the above structure in which atomized particles injected by the pump 121 are most effectively distributed within the body member 130.

Since the minute dust is first purified by the spray particles in the body member 130 and the fine dust is secondarily removed by the plate in the filtration plate means 150, It can be maintained.

As described above, the fine dust removing apparatus using the filtration plate according to the present invention comprises the blowing means for introducing indoor air, the spraying means for spraying the water, and the filtration plate means for purifying and discharging the fine dust of the contaminated air, The induced polluted air is sprayed on the sprayed particles by the spraying means and falls into the water tank, and is primarily cleaned and cleaned.
