Abstract

An ozone cleaning system includes a decontamination chamber, a utility chamber coupled to the decontamination chamber, and a utility assembly disposed within the utility chamber. The utility assembly is configured to decontaminate at least one of contaminated gear and contaminated equipment positioned in the decontamination chamber by treating organic carcinogens. The utility assembly includes an ozone generator configured to provide ozone to the decontamination chamber, a humidifying unit configured to provide humidity to the decontamination chamber, and a vacuum blower configured to at least one of (i) generate a vacuum within the decontamination chamber and (ii) pull the ozone from the decontamination chamber following a decontamination process.

First claim

The invention claimed is:

1. An ozone cleaning system comprising:
a housing defining an interior chamber and an outlet;
a dividing wall separating the interior chamber into a first chamber and a second chamber;
a door coupled to the housing, the door configured to facilitate selectively accessing the first chamber;
a filter at least one of positioned along or disposed within the dividing wall;
an ozone generator configured to generate ozone;
a humidifier configured to generate water vapor, wherein the ozone and the water vapor are provided to the first chamber to interact with an item disposed within the first chamber to remove contaminants from the item; and
a blower configured to drive contaminated air including any residual ozone, any residual water vapor, and the contaminants within the first chamber through the dividing wall and the filter to provide at least partially filtered air to the second chamber, through the second chamber to the outlet, and through the outlet such that the at least partially filtered air is exhausted into an ambient environment that surrounds the housing while the door is closed.

2. The ozone cleaning system of claim 1 , wherein the filter is configured to at least one of collect or neutralize at least a portion of at least one of the residual ozone or the contaminants.

3. The ozone cleaning system of claim 1 , further comprising a catalyst positioned between the outlet and the filter, wherein the blower is configured to drive the contaminated air through the filter and the catalyst, wherein the filter and the catalyst are configured to at least one of collect or neutralize at least a portion of at least one of the residual ozone or the contaminants to provide the at least partially filtered air.

4. The ozone cleaning system of claim 3 , wherein the filter and the catalyst are integrated into a single device.

5. The ozone cleaning system of claim 4 , wherein the single device is a photocatalytic oxidation filter that includes a light source.

6. The ozone cleaning system of claim 5 , wherein the light source is an ultraviolet light source.

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

8. 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 subchambers.

9. The ozone cleaning system of claim 8 , wherein the at least one divider is at least partially permeable.

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

11. The ozone cleaning system of claim 1 , wherein the housing is a compartment of a vehicle.

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

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