Abstract

An ozone cleaning system includes a first chamber, a second chamber coupled to the first chamber, and a utility assembly disposed within the second chamber. The utility assembly includes an ozone generator configured to provide ozone to the first chamber, a humidifying unit configured to provide water vapor to the first chamber, and a blower configured to at least one of (i) reduce air pressure within the first chamber or (ii) draw the ozone from the first chamber following a decontamination process.

First claim

The invention claimed is:

1. An ozone cleaning system comprising:
a housing defining an interior chamber, the housing including a dividing wall separating the interior chamber into (i) a first chamber configured to selectively receive contaminated equipment and (ii) a second chamber coupled to the first chamber;
an ozone generator configured to generate ozone;
a humidifying unit configured to generate water vapor, wherein the ozone generator and the humidifying unit provide the ozone and the water vapor to the first chamber such that moist, ozonated, clean air is circulated throughout the first chamber to interact with the contaminated equipment to generate moist, ozonated, contaminated air during a decontamination process of the contaminated gear;
a filter positioned along the dividing wall;
a catalyst, wherein the filter and the catalyst are configured to neutralize residual ozone and contaminants within the moist, ozonated, contaminated air; and
a blower configured to provide the moist, ozonated, contaminated air from the first chamber, through the filter and the catalyst, and out of the second chamber to an exterior environment that surrounds the housing following the decontamination process of the contaminated equipment.

2. The ozone cleaning system of claim 1 , wherein the filter is a photocatalytic oxidation filter that includes the catalyst and a light source.

3. The ozone cleaning system of claim 2 , wherein the light source is an ultraviolet light source.

4. The ozone cleaning system of claim 1 , wherein the catalyst is a titanium dioxide catalyst.

5. The ozone cleaning system of claim 3 , wherein the ultraviolet light source provides ultraviolet light having a wavelength spectrum between 250 nanometers and 415 nanometers.

6. The ozone cleaning system of claim 1 , wherein the first chamber includes at least one divider that subdivides the first chamber into a plurality of zones.

7. The ozone cleaning system of claim 6 , wherein the at least one divider is at least partially permeable.

8. The ozone cleaning system of claim 6 , wherein at least one of (i) the ozone generator is configured to facilitate providing the ozone to each of the plurality of zones individually or (ii) the humidifying unit is configured to facilitate providing the water vapor to each of the plurality of zones individually.

9. The ozone cleaning system of claim 1 , wherein the ozone cleaning system is a standalone unit.

10. The ozone cleaning system of claim 1 , wherein the ozone cleaning system is integrated into a compartment of a vehicle.

11. The ozone cleaning system of claim 1 , wherein the first chamber is a cab of a vehicle.

12. The ozone cleaning system of claim 1 , wherein the first chamber is a refuse compartment of a vehicle.
