Form 3

The washing water dropped from the washing water layer 13 after passing through the perforated plate 1 is stored in a water storage unit 14. As described above, the washing water circulates in the order of the water storage unit 14, the water pump 20, the water pump 17, the perforated plate 1, and the water storage unit 14.

The amount of washing water stored in the water storage unit 14 is detected by a float valve, and when the amount of washing water decreases and the water level in the water storage unit 14 drops, the water is supplied from the water supply pipe 13 via the electromagnetic valve 18a. The water is supplied to the water storage unit 14 and the supply is stopped when the water storage unit 14 becomes full. Also,
Since the cleaning water stored in the water storage unit 14 comes into contact with and contaminates the contaminated air, it is drained from the drain pipe 19 via the electromagnetic valve 18b at regular intervals.

In the summer, as shown in FIGS. 1 and 2, the humidity adjusting unit 2a is used as a dehumidifier. To clarify this, the heater 12a is not shown in FIG. In this case, the indoor or outdoor contaminated air taken in from the air inlet 9 is sent to the air purification chamber 8 after being dehumidified by passing through the humidity adjustment unit 2a as a dehumidifier.

In this case, the contaminated air is supplied to the humidity controller 2a.
And the dew point temperature can be lowered. Because the temperature of the contaminated air drops to a slightly higher temperature than the dew point temperature,
The contaminated air is sent to the air purification chamber 8 at a reduced temperature and humidity.

Thereafter, the contaminated air passes through the washing water layer 13 on the perforated plate 1 and comes into contact with the washing water to remove dust, odor components, harmful gas components, etc. from the contaminated air and purify the contaminated air. Air is obtained. In addition, the contaminated air is the layer
When passing through 3, the purified air is cooled by an amount corresponding to the latent heat of evaporation of the washing water. At this time, the purified air is humidified and contains water droplets. Thereafter, the purified air is passed through the demister 7 to remove water droplets contained in the purified air.

In this case, before the contaminated air is brought into contact with the washing water, the humidity of the contaminated air is reduced by dehumidifying by the dehumidifier humidity controller 2a. Furthermore, since the dew point of the contaminated air is lowered by dehumidifying the contaminated air, it is possible to cool the contaminated air to a temperature slightly higher than the dew point temperature, that is, a temperature lower than that when no dehumidification is performed.

Therefore, it is possible to obtain purified air having a lower humidity and a lower temperature than when no dehumidification is performed, and the purified air is supplied from the exhaust port 10 to a predetermined place through the humidity adjusting section 2b. Thereby, the over-humidification state of the purified air can be prevented. In this case, the humidity adjusting section 2b can be used as a dehumidifying section, or can be used as a simple passage.

The silica gel adsorbent absorbs moisture by using the dehumidifier humidity adjusting section 2a as a dehumidifying section, and by using the dehumidifier humidity adjusting section 2a and the dehumidifier humidity adjusting section 2b as a dehumidifying section. Is reproduced by the reproducing unit 11.

That is, by operating the heater 12b of the regenerating section 11, the regenerating section 11 is heated to about 100 ° by the operation of the heater 12b, and at the same time, the regenerating fan 22 is operated to remove water from the silica gel adsorbent. To regenerate it and exhaust the air used for regeneration outside.

Thus, excess air can be discharged from indoors to outdoors, and the indoors can be ventilated.
Furthermore, by continuously rotating and using the humidity adjusting device 4 in the circumferential direction, the dehumidifying portion is always provided with the regenerated and dried silica gel adsorbent, so that the humidity can be continuously adjusted. Becomes

On the other hand, in winter, as shown in FIG. 1 and FIG.
a is used as a humidifier, and the humidity adjusting unit 2b is used as a dehumidifier. Therefore, the indoor or outdoor contaminated air taken in from the intake port 9 is supplied to the humidity control unit 2a as a humidifier.
, And is sent to the air purification chamber 8.

The humidity controller 4 dehumidifies in a humidity controller 2b as a dehumidifier, and releases the dehumidified water in a humidity controller 2a as a humidifier. That is, the contaminated air is humidified by mixing the dehumidified water into the contaminated air. When the contaminated air is humidified, the silica gel adsorbent is also regenerated. This allows
The regeneration of the silica gel adsorbent can be easily performed at the time of operation of the air purification device.

The heater 12b is not shown in FIG. 3 in order to clarify that the silica gel adsorbent is regenerated in the humidity adjusting section 2a and that the regenerating section 11 is not used in principle.

In this case, the contaminated air is supplied to the humidity controller 2a.
And the dew point temperature can be raised. Because the temperature of the contaminated air drops to a slightly higher temperature than the dew point temperature,
The contaminated air is sent to the air purification chamber 8 with the temperature and humidity raised.

Thereafter, the contaminated air passes through the washing water layer 13 on the perforated plate 1 and comes into contact with the washing water to remove dust, odor components, harmful gas components, etc. from the contaminated air and purify the contaminated air. Air is obtained.

When the contaminated air passes through the washing water layer 13, the purified air is cooled by an amount corresponding to the latent heat of evaporation of the washing water. At this time, the purified air is humidified, It will contain water droplets. Thereafter, the purified air is passed through the demister 7 to remove water droplets contained in the purified air.

In this case, before the contaminated air is brought into contact with the washing water, the humidity of the contaminated air is increased by humidification by the dehumidifier humidity controller 2a. Further, since the dew point of the contaminated air is raised by humidifying the contaminated air, the temperature of the contaminated air can be raised to a temperature slightly higher than the dew point temperature, that is, a temperature higher than when no humidification is performed.

Therefore, it is possible to obtain purified air having a higher humidity and a higher temperature than in the case where no humidification is performed. Is done. This can prevent an increase in the heating load for heating the purified air.

The regeneration of the silica gel adsorbent is carried out in principle in the humidity controller 2a as a humidifier. However, if the regeneration capacity is insufficient, the regeneration in the regeneration unit 11 can be carried out.
