DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blow-up type cleaning / cooling apparatus in which an air cleaning chamber and a steam / water separator are integrally provided.

[0002]

2. Description of the Related Art In recent years, sterile and dust-free environments have been required in industries such as medical treatments and semiconductors requiring high precision for protecting the safety of the human body. Conventionally, in order to make the room have such an environment, bacteria elimination and dust removal have been performed by a system using a filter.

However, in the filter system, there are various problems such as a decrease in performance due to accumulation of dust and the like, charging of dust in the air by the filter and the like, and a need for a ventilation device because it is impossible to remove toxic gas generated in the room. was there. In order to solve this problem, Japanese Patent Publication No. 57-55117
There has been proposed a recirculation type air cleaning device provided outside a room.

[0004] That is, as shown in FIG. 4, the air in the air-conditioned room is cleaned by a conduit and a fan.
Air is introduced into the chamber 0, and cold water is sprayed from the spray nozzle 21 to humidify the water. Fine particles such as germs and dust in the gas can be dissolved or suspended in water to remove them. This is sent from a discharge pipe 22 opened in the lower part of the center of the cleaning cyclone 20 to the next water / water separation cyclone 23 where it is removed. The air exiting from the water / water separation cyclone 23 is heated to an appropriate temperature, adjusted for humidity and temperature, and then circulated again indoors. The sprayed water and the water removed by the gas-liquid separation cyclone 23 are collected in a water tank 24 and sent to the spray nozzle 21 again.

[0005] In such a reflux-type air purifying apparatus,
The liquid is sprayed on the circulating gas to directly control the temperature of the air. By spraying the liquid, fine particles such as germs and dust in the gas can be removed.

[0006]

However, in the above-mentioned reflux type air cleaning device, it is necessary to provide two types of cyclones for cleaning and cooling and for separating water and water. For this reason, compared with the conventional air purifying device using a filter, a large area for installing the device is necessary, and in order to provide a discharge pipe to the next process in each cyclone,
Space in the height direction is required. Due to such restrictions, it is often impossible to provide the recirculation type air cleaning device, and only to provide a device using a filter having various problems.

The present invention has been proposed to solve the above-mentioned drawbacks of the prior art, and its object is to integrate two types of cyclones for cleaning and cooling and for separating water and water. Accordingly, an object of the present invention is to provide a blow-up type cleaning / cooling device which can be installed in a limited space and has a higher cleaning effect than a device using a filter.

[0008]

In order to achieve the above object, in the blow-up type cleaning and cooling apparatus of the present invention, an air inlet is provided on a lower side wall, and the air is introduced to clean the air introduced therein. An air purifying chamber provided with a spray nozzle for jetting water, a steam-water separator provided in a funnel shape so that a side wall spreads upward, and a spray water supply for supplying water to the spray nozzle Means are provided, such that the funnel-shaped side wall of the steam separator expands upward in the center of the air purification chamber so that the air purification chamber narrows upward.

[0009]

The operation of the present invention having the above configuration is as follows. That is, when the air that needs to be purified is introduced into the purification chamber from the air introduction port at the bottom of the air purification chamber, it flows in a swirling direction in the ascending direction, and becomes narrower by the funnel-shaped inner wall toward the upper part. It passes through the upper vent and is sent to the steam separator inside the funnel-shaped inner wall. At this time, in the air purifying chamber, droplets are sprayed from a spray nozzle connected to the spray water supply means, and the air becomes clean air by removing dust, bacteria, and the like by the droplets. The purified air is
Droplets are removed by a cyclone-type water separator separated from the bottom by the funnel-shaped inner wall, the humidity is adjusted, and the air is discharged from the air outlet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. That is, the blow-up type cleaning / cooling device of this embodiment is surrounded by a cylindrical outer wall 2 provided with an air inlet 1 at a lower portion. A funnel-shaped inner wall 3 extending upward is provided at the center of the inside, an air purification chamber 4 having a lower portion that is wider at the outer side of the inner wall 3 and narrower toward the upper portion, and a lower portion at the inner side. It is divided into two chambers, that is, a steam-water separator 5 that becomes wider toward the upper part. These two chambers are communicated with each other by a vent 6 opened on the inner wall 3 near the top plate, and an introduction wall 7 for introducing air to the steam separator 5 is provided on the air purification chamber 4 side of the vent 6. Is provided.

A plurality of water supply pipes 9 are arranged vertically inside the air purification chamber 4 along the inner wall 3, and these water supply pipes 9 are provided with a large number of spray nozzles 8. In addition, the direct expansion coil 1 through which the refrigerant at a constant temperature flows along the inner surface of the outer wall 2
0 is helically disposed and connected to a cooling / circulating means (not shown).

On the other hand, the steam separator 5 is provided with an exhaust pipe 11 in the vertical direction of the center, and the lower end thereof is provided with the steam separator 5.
It is open at the bottom center. The tip of this exhaust pipe 11
It is extended into the room where air conditioning is performed. In addition, steam-water separator 5
A collecting pipe 12 for the water separated by the steam separator 5 is connected to the funnel-shaped bottom of the above, and this is connected to a means for circulating spray water.

As a means for circulating the spray water, a water tank 13 is provided below the two chambers of the air purification chamber 4 and the steam separator 5 integrally with the two chambers 4 and 5. The water tank 13 is provided with a sterilizing filter 14 and a suction pipe 15 below the sterilization filter 14. The suction pipe 15 is connected to the water supply pipe 9 in the air cleaning chamber 4 via a pump 16. The operation of the blow-up type cleaning / cooling device of the present embodiment configured as described above is as follows.

That is, the air for cleaning is supplied to the air inlet 1 at the lower part of the air cleaning chamber 4 by a conduit and a fan (not shown).
Is introduced into the air purification chamber 4 and further swirled upward in the air purification chamber 4. At this time,
Since the cleaning chamber 4 is gradually narrowed toward the upper part by the inner wall 3, the flow velocity of the air increases accordingly. This air contains sterilized cooling water that has passed through the sterilizing filter 14 in the water tank 13 below the air purifying chamber 4 and the suction pipe 1.
5. 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 to have a temperature substantially equal to that of the cooling water, and excess water is condensed and dewatered. Fine particles such as bacteria and dust in the air are dissolved or suspended in water. The water containing the fine particles such as germs and dust returns to the lower water tank 13 and is filtered by the sterilizing filter 14 to remove the fine particles such as germs and dust, and then reused as cleaning water.

The air that has been cleaned in the air cleaning chamber 4 contains sprays of water that has been sprayed, and the humidity of the air becomes supersaturated. This air becomes high speed near the top plate of the air purification chamber 4 and hits the introduction wall 7, and the ventilation port 6 provided in the inner wall 3.
It is discharged to the steam separator 5 inside the inner wall 3 more smoothly. In the steam separator 5, as the air blown from the upper part moves to the lower part, the flow velocity increases, and the air collides with the inner wall 3, so that excess water is removed. Accordingly, droplets are removed inside the cyclone-type water / water separator 5 and turned into saturated air to be sent out from the exhaust pipe 11 to the room to be air-conditioned.
Also at this time, fine particles such as germs and dust remaining in the air are dissolved or suspended by the removed water and return to the water tank 13 below the collection pipe 12.

As described above, in the blow-up type cleaning apparatus of the present embodiment, the air flow is of the blow-up type, so that the flow path to the next step is shortened. And the water / water separator are integrated, and each can be shaped as a cyclone. Furthermore, since the taper is not provided at the lower part of the device, it can be installed in a limited space. In addition, a cleaning device having a high cleaning effect can be obtained.

The present invention is not limited to the above-described embodiment, and specific shapes of the respective members, or respective mounting positions and methods can be appropriately changed. For example, the clean air discharged from the steam separator is not limited to the saturation humidity, and the humidity can be adjusted by mixing with the dry air. Further, the humidity can be adjusted by utilizing a difference in saturation humidity due to a temperature difference between the temperature in the air cleaning chamber and the room temperature.

Further, a reheat heater may be provided on a path of an exhaust pipe connected from the steam separator to an air-conditioned room. That is, since the air discharged from the steam separator is at a low temperature due to the heat exchange between the spray water and the direct expansion coil, the air is cooled to an appropriate temperature using a reheat heater or the like. And humidity can be adjusted.

Further, the temperature can be adjusted by simply spraying water on the blown-up air without providing a direct expansion coil in the steam-water separation air, and the air can be cleaned.

[0020]

In the blow-up type cleaning apparatus of the present invention, by providing the funnel-shaped wall, the steam-water separator can be integrally provided inside the air cleaning chamber, and the conventional cyclone taper can be provided. Since the useless space such as the lower part of the unit is eliminated and the entire device for purifying air can be made compact, a device having a high air purifying effect can be installed in a small space.
