[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a blow-up type cleaning device in which an air purifying chamber and a steam/water separator are integrated, and in particular, a demister for water condensation is provided in the steam/water separator. This relates to a blow-up type cleaning device.

BACKGROUND OF THE INVENTION In recent years, a sterile and dust-free environment has been required for medical care to protect the safety of the human body and industries such as semiconductors that require precision. Conventionally, in order to create such an environment indoors, sterilization and dust removal were performed using a system that used a filter.

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.

That is, 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.

[0005] In the above-mentioned reflux type air purifying device,
The temperature of the air is directly controlled by spraying a liquid onto the circulating gas. By spraying this liquid, microscopic particles such as germs and dust can be removed from the gas.

[0006]

However, in the above-mentioned reflux type air purifying device, it is necessary to provide two types of cyclones, one for cleaning and one for separating air and water. Therefore, compared to conventional air purifying devices using filters, a larger area is required to install the device. Further, each cyclone requires space in the height direction to provide a discharge pipe to the next process. 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.

The present invention was proposed to solve the above-mentioned drawbacks of the prior art, and its purpose is to integrate two types of devices, one for clean cooling and one for air/water separation. Therefore, it is an object of the present invention to provide a blow-up type cleaning device that can be installed in a limited space and has a higher cleaning effect than a device using a filter.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on the embodiments shown in FIGS. 1 to 4.

FIGS. 1 to 3 show an embodiment of the invention according to claim 1.

That is, the blow-up type cleaning device of this embodiment has the following features:
It consists of a cylindrical air purifying chamber 1 and a steam separator 2 provided on its top plate. An air inlet 3 is provided in the lower part of the side wall of the air purifying chamber 1 and opens in the tangential direction thereof, and an air outlet 4 is provided in the top plate that opens in the center thereof. The air purification chamber 1 and the steam separator 2 are communicated with each other through the air outlet 4. On the inner surface of the side wall of the air cleaning chamber 1, a direct expansion coil 5 through which a refrigerant at a constant temperature flows is spirally arranged along the side wall and connected to a refrigerant cooling/circulating means (not shown). Further, in the center of the air purification chamber 1, a water supply pipe 7 is disposed vertically in the vertical direction, and a plurality of spray nozzles 6 are disposed around the water supply pipe 7. On the other hand, a water tank 8 is provided at the bottom of the air purification chamber 1 as a means of circulating spray water.
is provided integrally with the air cleaning chamber 1. This tank 8
A sterile filter 9 and a suction pipe 10 are disposed below the filter, and the suction pipe 10 is connected to a water supply pipe 7 in the air purification chamber 1 via a pump 11.

On the other hand, the air purification chamber 1 is installed in the steam/water separator 2.
A baffle plate 12 having a size that can sufficiently cover this opening is provided above the air outlet 4 communicating with the air outlet 4, and a demister 13 for moisture condensation is further provided above the baffle plate 12. Further, the steam/water separator 2 is provided with a tapered portion 14 extending from one side above the demister 13 to the top plate.
An air outlet 15 is provided on a part of the facing surface. This discharge port 15 is connected to a room that is air-conditioned.

The operation of the blow-up type cleaning device equipped with the demister of this embodiment constructed as described above is as follows.

That is, air for cleaning is introduced from the air inlet 3 at the bottom of the air cleaning chamber 1 by a conduit and a fan (not shown), and is further blown up while swirling inside the air cleaning chamber 1. At this time, water tank 8 at the bottom of air purification chamber 1
The sterilized cooling water that has passed through the sterile filter 9 is passed through the suction pipe 10.
, is sprayed into the air cleaning chamber 1 from the spray nozzle 6 of the water supply pipe 7 via the pump 11. Therefore, the introduced air quickly exchanges heat with the refrigerant in the direct expansion coil 5 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 moisture containing microscopic particles such as bacteria and dust is removed from the lower water tank 8.
The water is then returned to the sterile filter 9 to be filtered to remove microscopic particles such as germs and dust, and then used again as clean water.

The air purified in the air purification chamber 1 contains sprayed moisture droplets, and its humidity becomes supersaturated. This air is further blown up and rises from the air outlet 4 provided on the top plate of the air purifying chamber 1 to the steam separator 2 above it. This air hits the baffle plate 12 at the inlet of the steam separator 2 and is uniformly diffused. The diffused air rises from around the baffle plate 12, and when passing through the demister 13, excess moisture in the air is condensed and removed, becoming saturated air and flowing along the tapered portion 14 to the outlet 1.
Exhausted from 5. At this time, microscopic particles such as germs and dust remaining in the air are dissolved or suspended by the removed moisture and returned to the lower water tank 8.

In this case, since the moisture sprayed in the air purification chamber 1 has passed through the sterilization filter 9, the demister 1
3. Bacteria will not grow inside the chamber and clogging will not occur.

As described above, in the blow-up type cleaning device equipped with the demister of this embodiment, the air flow is blow-up type to shorten the flow path to the next process, and the air flow is used for cleaning and air/water separation. Because it is a device that integrates two types of devices, it can be made compact, and since there is no tapered part at the bottom of the device, it is possible to install a highly effective device in a limited space. Can be done.

It should be noted that the present invention is not limited to the above-described embodiments, and the specific shape of each member or the mounting position and method of each member can be changed as appropriate.

For example, as shown in FIG. 4, it is also possible to provide a reheat heater 16 above the demister 13 inside the steam/water separator. That is, in a sterile and dust-free room, it is necessary to control the temperature of the clean air discharged from the cleaning device according to the required temperature conditions. For this purpose, reheat heaters have traditionally been installed in ducts in ceilings and other locations that are difficult to maintain. For this reason, it requires a large amount of space such as a walkway for maintenance and space under the ceiling, making it difficult to install it in a limited space. In order to solve this problem, we installed a demister 1 inside the steam separator 2 of the blow-up type purifier.
By providing a reheat heater 16 on the top of 5 to control the temperature of clean air, maintenance becomes easy and the problem of installation location can be solved.

[0024] Furthermore, the clean air discharged from the steam separator is not limited to a saturated humidity, but the humidity can also be adjusted by mixing it with dry air. 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.

On the other hand, it is also possible to control the temperature and purify the air by simply spraying water onto the blown up air, without providing a direct expansion coil in the steam/water separation gas.

[0026]

As described above, according to the invention of claim 1, since the steam and water separator is integrally provided in the upper part of the air purification chamber,
Since the entire air purifying device can be made compact, a device with a high air purifying effect can be installed in a small space.

Furthermore, according to the invention of claim 2, by providing a reheat heater for temperature control within the steam/water separation gas, maintenance is simplified and the installation can be done without considering the installation location. be able to.
