The injection pipe 11 and the suction pipe 12 of the sterilization device 20 is installed to seal through one side of the sealed space 10.

The sterilization apparatus 20 injects the sterilization gas generated therein through the injection tube 11 into the sealed space 10, and sucks the internal air of the sealed space 10 back into the suction tube 12. Sterilization is performed through the operation of circulating.

2 is a block diagram of a sterilization apparatus of an enclosed space using ozone and humidity according to the present invention.

As shown, the sterilization apparatus 20 of the present invention,

A steam generator 21 for generating steam and injecting it into the enclosed space 10, an ozone generator 22 for generating ozone (O ₃ ) and injecting it into the enclosed space 10, and the enclosed space 10. The first filter 23 to remove the fine particles contained in the air discharged from the), the catalytic converter 24 to block the toxicity contained in the air discharged through the first filter 23, and the catalytic converter Humidity removal unit 25 for removing the moisture contained in the air discharged through the 24 and, connected to the rear end of the humidity removal unit 25, by sucking the internal air of the sealed space 10 and discharged The circulation pump 26 and the heating unit 27 is connected to the rear end of the circulation pump 26 to generate and inject hot air into the closed space 10, and is discharged through the heating unit 27 The second filter 28 removes the fine particles contained in the air and discharges them to the steam generator 22. The.

Here, the steam generator 21 may be further equipped with a distilled water cartridge 21a which is administered to the steam generator 21 and installed to be detachable.

In addition, an oxygen generator 29 for supplying oxygen may be further configured at an inlet of the ozone generator 22.

In addition, the injection pipe 11 has a plate (11a) is installed, the steam (G1) through the steam generator 21, the ozone (G2) through the ozone generator 22 is separated from each other in a sealed space (10) To be added.

The steam generator 21 is a device for converting the distilled water provided from the distilled water cartridge 21a into a gaseous state. The steam generator 21 converts the distilled water, which is liquid, into gas through a means such as heater heating or ultrasonic vibration.

The first filter 23 and the second filter 28 are preferably a HEPA filter.

In addition, the oxygen generator 29 is a device for generating oxygen gas, and provides the oxygen gas to the ozone generator 22, the ozone generator 22 generates a high concentration of ozone.

The heating unit 27 is an air heating device for raising a temperature by injecting warm air into the enclosed space 10, and is provided with heating means such as a heater to maintain the internal air at a predetermined temperature.

The internal temperature of the closed space 10 is preferably maintained at 40 ~ 60 ℃, the reason for maintaining the temperature of the closed space 10 to a certain temperature is to improve the sterilization efficiency.

At the same time to the heating unit 27 is dropped by raising the temperature of the ozone (O ₃₎ gas injected into the space 10 is closed is discharged from the ozone generator 22 at a constant temperature, so the ozone (O ₃ As the temperature of) increases, ozone (O ₃ ) is more rapidly separated into oxygen (O ₂ ) and oxygen atoms (O) (OH radical separation) to quickly and efficiently perform the sterilization effect on the disinfectant.

If there is no such heating portion 27, a problem that takes a long time to react in the closed chamber 10 is ozone (O ₃ ) and oxygen (O ₂ ).

Here, the heating temperature of ozone gas is preferably in the range of 100 to 400 ° C.

On the other hand, the air blowing fan 13 for circulating the internal air inside the sealed space 10, and a humidifier 14 for providing a constant humidity therein is further installed.

The operation of the sterilization apparatus of a closed space using the present invention ozone and humidity configured as described above will be described.

First, the sealed space 10 to be sterilized and disinfected, for example, a clean room or an operating room or a space such as an incubator, and the injection pipe 11 and the suction pipe 12 of the sterilization device 20 are closed. It penetrates through the space 10 and is connected.

And the operation for sterilization of the sealed space 10 is started.

The sterilization disinfection time is set and operation started through an operation switch not shown.

When the sterilization operation is started in this way, the heating unit 27 is operated, the circulation pump 26 is operated, and the hot air generated by the heating unit 27 is driven by the circulation pump 26 to operate the second filter 28. And the ozone generator 22 are injected into the enclosed space 10 through the injection pipe 11.

Therefore, the internal temperature of the enclosed space 10 is increased, and the heating unit 27 automatically maintains the internal temperature of the enclosed space 10 between 40 to 60 ° C. by a temperature sensor not shown. Temperature controlled.

In this state, the ozone generator 22 and the steam generator 21 start driving.

Therefore, the steam discharged from the steam generator 21 and the ozone gas discharged from the ozone generator 22 are injected into the sealed space 10 through the injection pipe 11.

Steam and ozone gas injected into the sealed space 10 are sterilized in the sealed space 10.

Here, the oxygen generator 29 may be selectively driven at the same time.

At this time, the oxygen generator 40 generates oxygen gas to be provided to the inlet side of the ozone generator 22, in which the ozone generator 22 receives oxygen and discharges a high concentration of ozone.

Therefore, the vapor and the high concentration of ozone gas perform a very efficient sterilization operation in the closed space 10.

Meanwhile, according to the present invention, during sterilization operation, hot air by the heating unit 27 is first introduced into the enclosed space 10, or steam and hot air are simultaneously introduced, or steam is supplied first and then a predetermined time It can be set to perform sterilization treatment in various ways, such as after supplying ozone.

When the sterilization gas (steam and ozone gas) is introduced into the enclosed space 10, the gas is transferred to the sterilization apparatus 20 through the suction pipe 12 again by the suction force of the circulation pump 26.

That is, the inside air of the enclosed space 10 discharged through the suction pipe 12 is removed with fine particles while passing through the first filter 23, and the toxicity is blocked while passing through the catalytic converter 24.

Water is removed again while passing through the humidity removing unit 25, and fine particles are removed while passing through the second filter 28 through the circulation pump 26 and the heating unit 27, and the ozone generator 22 again. Through the circulation flowing into the closed space 10 is repeated.

Meanwhile, the blowing fan 13 installed inside the sealed space 10 rotates to cause convection of air in the sealed space 10, and the humidifier 14 operates to move the inside of the sealed space 10. By maintaining a constant humidity, it provides an environment to maximize the sterilization efficiency.

Then, when the set time for the sterilization sterilization operation has elapsed, the steam generator 21, ozone generator 22, circulation pump 26, heating unit 27, oxygen generator 29, blower fan 13 and The driving of the drying apparatus 14 is stopped to end the sterilization operation.

Figure 3 is another embodiment of the sterilization apparatus of the closed space using ozone and humidity according to the present invention.

As shown, the present invention is a sealed space 10 is connected to the injection pipe 11 of the sterilization device 20 only, the suction pipe 12 is not connected to the sterilization device 20 is a closed space ( It is a configuration to be discharged to the outside in 10).

In this case, in the sterilization apparatus configuration of Figure 2, only the suction pipe 12 is separated and installed independently in the closed gorge 10, the operation is the same. However, the suction pipe 12 serves only to discharge the air and does not play a role of circulating the air.

In addition, according to the present invention, the sterilization apparatus 20 'can be configured to be installed in the closed space (10).

In this case, the sterilizing gas discharged through the inlet tube of the sterilization apparatus 20 'is circulated in the sealed space 10, and then sucked back into the suction tube, and the effect is the same. .
