いる。However, the filter system has various problems such as a decrease in performance due to the accumulation of dust, charging of dust in the air by the filter, and the need for ventilation equipment because it is impossible to remove toxic gases generated indoors. was there. In order to solve this problem, as Special Publication No. 57-55117,
A recirculation type air purifying device installed outdoors has been proposed.

。Specifically, as shown in FIG.
Air is introduced into the chamber 0, and cold water is sprayed from the spray nozzle 21 to humidify the air. These droplets can dissolve or suspend fine particles such as germs and dust in the gas and remove them. This is sent from a discharge pipe 22 opened at the lower center of the cleaning cyclone 20 to the next stage, a steam/water separation cyclone 23, where drips are removed. The air leaving the steam/water separation cyclone 23 is heated to an appropriate temperature, and after the humidity and temperature are adjusted, it is circulated indoors again. The sprayed moisture and the moisture removed by the gas-liquid separation cyclone 23 are collected in the water tank 24 and sent to the spray nozzle 21 again.

設けるしかない場合が多い。However, in the above-mentioned reflux type air purifying device, it is necessary to provide two types of cyclones, one for cleaning and cooling and one for separating air and water. For this reason, compared to conventional air purification devices using filters, a larger area is required to install the device, and each cyclone is provided with its own discharge pipe to the next process.
Space in the height direction is required. Due to such restrictions, it is not possible to provide the above-mentioned recirculation type air purifying device, and in many cases, the only option is to provide a device using a filter, which has various problems.

された後に、再度清浄用水として利用される。That is, the air for cleaning is supplied to the air inlet 1 at the bottom of the air cleaning chamber 4 by a conduit and a fan (not shown).
The air is then introduced into the air purification chamber 4, and further blown up while swirling in the upward direction within the air purification chamber 4. At this time,
Since the cleaning chamber 4 gradually becomes narrower toward the top due to the inner wall 3, the air flow rate increases accordingly. This air contains sterile cooling water that has passed through the sterilizing filter 14 in the water tank 13 at the lower part of the air purifying chamber 4.
, is sprayed from the spray nozzle 8 of the water supply pipe 9 via the pump 16. Therefore, the introduced air quickly exchanges heat with the refrigerant in the direct expansion coil 10 and the sprayed droplets, and reaches a temperature approximately equal to that of the cooling water, and excess water is condensed and deprived of water. Microscopic particles such as germs and dust in the air are dissolved or suspended in the moisture. This water containing microorganisms, dust, and other fine particles returns to the lower water tank 13, is filtered by a sterilizing filter 14, removes germs, dust, and other microscopic particles, and is used again as clean water.

１２より下部の水槽１３に戻る。The air purified in the air purification chamber 4 contains sprayed moisture droplets, and its humidity becomes supersaturated. This air becomes high-speed near the top plate of the air purification chamber 4 and hits the introduction wall 7, and is then connected to the ventilation hole 6 provided in the inner wall 3.
The water is more smoothly discharged to the steam separator 5 inside the inner wall 3. In the steam/water separator 5, as the air blown from the upper part moves to the lower part, its flow velocity increases, collides with the inner wall 3, and excess water is taken away. Therefore, droplets are removed inside this cyclone-type steam/water separator 5, and the saturated air is sent out from the exhaust pipe 11 into the room to be air-conditioned. At this time as well, fine particles such as germs and dust remaining in the air are dissolved or suspended by the removed moisture and returned to the water tank 13 located below the collection pipe 12.

とすることができる。As described above, in the blow-up type cleaning device of this embodiment, the air flow is blow-up type, the flow path to the next process is shortened, and the funnel-shaped inner wall allows the air purification chamber to be closed. The two chambers of the chamber and the steam/water separator are integrated, and each can be shaped like a cyclone.Furthermore, since there is no tapered section at the bottom of the device, it can be installed in a limited space. Moreover, a cleaning device with high cleaning effect can be obtained.

Furthermore, the humidity can also be adjusted by utilizing the difference in saturated humidity due to the temperature difference between the temperature inside the air purification room and the room temperature.

In other words, the air discharged from the steam separator is at a low temperature due to the spray water distribution and heat exchange with the direct expansion coil, so a reheat heater or the like is used to heat this air to an appropriate temperature. and humidity can be adjusted.
