Abstract

An ozone laundry system and its method of use with continuous batch or tunnel washers is provided, wherein ozone can be injected into a plurality of different chambers along the continuous batch or tunnel washer and wherein the interfacing of a plurality of system controls occurs on a centralized HMI controller along with DOM and ORP monitoring. Vacuum sensors over vacuum switches are used to compensate for a slightly positive pressure at the ozone outlet, due to a long tube run with a weak vacuum.

Claims

1. An ozone laundry system for connection to a continuous batch or tunnel washer, the ozone laundry system comprising:

a single cabinet for enclosing a multiplicity of components that form the ozone laundry system;

a series of compression fittings protruding from the single cabinet and connected to a multiplicity of components that form the ozone laundry system for providing a connection to a compressed air input source and at least two output streams of generated ozone to the continuous batch or tunnel washer;

at least one two-channel meter having a dissolved ozone monitor and an oxidation reduction potential monitor;

a human machine interface; and

a power source.

2. The ozone laundry system of claim 1, wherein the multiplicity of components that form the ozone laundry system includes at least one pressure regulator, a plurality of solenoids, a humidity removal device, at least one oxygen generator, at least one O² sensor, at least one flow meter, at least one ozone generator, a plurality of valves, at least one vacuum sensor and a programmable logic circuit.

3. The ozone laundry system of claim 2, wherein the at least one oxygen generator supplies generated ozone to a first output compression fitting of the series of compression fittings for control of a level of dissolved ozone in the continuous batch or tunnel washer and in addition supplies generated ozone to a set of three output compression fittings for supplying ozone into a fresh water stream in at least three different zones or chambers of the continuous batch or tunnel washer.

4. The ozone laundry system of claim 2, further comprising at least two oxygen generators, at least two ozone generators and a crossover network.

5. The ozone laundry system of claim 4, wherein a first ozone generator of the at least two ozone generators supplies generated ozone to a first output compression fitting of the series of compression fittings for control of a level of dissolved ozone in the continuous batch or tunnel washer.

6. The ozone laundry system of claim 4, wherein a second ozone generator of the at least two ozone generators supplies generated ozone to a set of three output compression fittings for supplying ozone into a fresh water stream in at least three different zones or chambers of the continuous batch or tunnel washer.

7. The ozone laundry system of claim 1, wherein the at least one two-channel meter comprises a second two channel meter having a pH monitor and a second oxidation reduction potential monitor.

8. The ozone laundry system of claim 1, wherein the human machine interface is a touch-screen sensitive device.

9. The ozone laundry system of claim 1, wherein the system can be controlled locally, through an intranet or over the Internet by laptop, personal computer, tablet PC or a hand held computing device.

10. The ozone laundry system of claim 1, further comprising a plurality of programmable alarm functions.

11. The ozone laundry system of claim 2, wherein the humidity removal device is at least one coalescing filter having a filament material positioned there within.

12. The ozone laundry system of claim 1, further comprising a second cabinet for housing at least one oxygen concentrator.

13. The ozone laundry system of claim 12, wherein the system can entrain ozone along a fresh water stream to at least six different zones of the continuous batch or tunnel washer.

14. The ozone laundry system of claim 1, wherein the oxidation reduction potential is measured at mid-process point and at an end process point.

15. The ozone laundry system of claim 14, wherein the end process point is a press, pan which is used to catch water from a system press and a press reuse water line/flow chamber of the system.

16. The ozone laundry system of claim 2, wherein the vacuum sensor transmits vacuum/pressure levels to the programmable logic circuit interfacing with the human machine interface.

17. The ozone laundry system of claim 2, further comprising a plurality of variable programmed set points on different zones of the system for sensing vacuum/pressure levels.

18. An ozone laundry system for connection to a continuous batch or tunnel washer, the ozone laundry system comprising:

two or more cabinets for enclosing a multiplicity of components that form the ozone laundry system;

a series of compression fittings protruding from at least one of the two more cabinets and connected to a multiplicity of components that form the ozone laundry system for providing a connection to a compressed air input source and at least two output streams of generated ozone to the continuous batch or tunnel washer;

at least one two-channel meter having a dissolved ozone monitor and an oxidation reduction potential monitor;

a human machine interface; and

a power source.

19. The ozone laundry system of claim 18, wherein the multiplicity of components that form the ozone laundry system includes at least one pressure regulator, a plurality of solenoids, a humidity removal device, at least one oxygen generator, at least one O² sensor, at least one flow meter, at least one ozone generator, a plurality of valves, at least one vacuum sensor and a programmable logic circuit.

20. The ozone laundry system of claim 18, further comprising:

at least two oxygen generators,

at least two ozone generators, and

a crossover network,

wherein a first ozone generator of the at least two ozone generators supplies generated ozone to a first output compression fitting of the series of compression fittings for control of a level of dissolved ozone in the continuous batch or tunnel washer and a second ozone generator of the at least two ozone generators supplies generated ozone to a set of three output compression fittings for supplying ozone into a fresh water stream in at least three different zones or chambers of the continuous batch or tunnel washer.

21. The ozone laundry system of claim 18, wherein the at least one two-channel meter comprises a second two-channel meter having a pH monitor and a second oxidation reduction potential monitor.

22. The ozone laundry system of claim 19, wherein the humidity removal device is at least one coalescing filter having a filament material positioned there within.

23. The ozone laundry system of claim 18, wherein the oxidation reduction potential is measured at mid-process point and at an end process point, wherein the end process point is a press pan which is used to catch water from a system press and a press reuse water line/flow chamber of the system.

24. The ozone laundry system of claim 18, wherein the system can entrain ozone along a fresh water stream to a multiplicity of different zones of the continuous batch or tunnel washer.

25. The ozone laundry system of claim 18, further comprising a plurality of variable programmed set points on different zones of the system for sensing vacuum/pressure levels.
