Abstract

Apparatus and methods for treatment of liquids by generating hydroxyl radicals through the dissolution of water molecules by hydraulic cavitation.

Claims

1. A hydraulic cavitation device for treating a body of liquid comprising:

a body including an upstream and a downstream end and an internal, unidirectional flow channel extending therethrough along an axis of the body from the upstream end to the downstream end, the body further including an orifice plate situated proximate the upstream end of the unidirectional flow channel and having an orifice defined therethough to allow for passage of liquid from the upstream end to the downstream end of the device, the orifice having a diameter smaller than that of the flow channel at the upstream end, the flow channel including a first portion downstream of the orifice plate that tapers inwardly in a downstream direction along the axis toward a second portion of the flow channel, the second portion tapering outwardly along the axis in a downstream direction toward the downstream end.

2. The device of claim 1 wherein the body further comprises an insert situated at the upstream end thereof adjacent the orifice plate, the insert having an opening extending therethrough along the axis to allow for passage of liquid from the upstream end, and through the orifice towards the downstream end of the device.

3. The device of claim 2 wherein the insert is removable.

4. The device of claim 2 wherein the insert has a constant internal diameter.

5. The device of claim 2 wherein the insert and the orifice plate define a monolithic structure.

6. The device of claim 1 wherein the orifice plate is positioned generally perpendicular to the axis.

7. The device of claim 1 wherein the body further comprises a passageway extending therethrough generally perpendicular to the axis.

8. The device of claim 1 wherein the flow channel further includes a throat portion of substantially constant internal diameter situated intermediate the orifice plate and the first portion of the flow channel.

9. The device of claim 8 wherein the body further comprises a passageway extending therethrough into the throat portion.

10. The device of claim 1 wherein the flow channel includes a minimum diameter point situated intermediate the first portion and the second portion.

17. The device of claim 1 wherein the flow channel further includes a throat portion of substantially constant internal diameter situated intermediate the orifice plate and the first portion of the flow channel.

18. The device of claim 17 wherein the body further comprises a passageway extending therethrough into the throat portion.

11. A hydraulic cavitation device for treating a body of liquid comprising:

a body including an upstream and a downstream end and an internal, unidirectional flow channel extending therethrough along an axis of the body from the upstream end to the downstream end, the body including an orifice plate situated proximate the upstream end of the unidirectional flow channel and having an orifice defined therethough, the orifice having a diameter smaller than that of the flow channel at the upstream end, the body further including an insert situated at the upstream end thereof adjacent the orifice plate, the insert having an opening extending therethrough along the axis to allow for passage of liquid from the upstream end, and through the orifice towards the downstream end of the device.

12. The device of claim 11 wherein the insert is removable.

13. The device of claim 11 wherein the insert has a constant internal diameter.

14. The device of claim 11 wherein the insert and the orifice plate define a monolithic structure.

15. The device of claim 11 wherein the orifice plate is positioned generally perpendicular to the axis.

16. The device of claim 11 wherein the body further comprises a passageway extending therethrough generally perpendicular to the axis.

19. The device of claim 11 wherein the flow channel includes a minimum diameter point situated intermediate the first portion and the second portion.

20. A method of treating a body of liquid comprising:

passing the liquid through a cyclonette that includes a body having an upstream and a downstream end and an internal, unidirectional flow channel extending therethrough along an axis of the body from the upstream end to the downstream end, the body further including an orifice plate situated proximate the upstream end of the unidirectional flow channel and having an orifice defined therethough to allow for passage of the liquid from the upstream end to the downstream end of the device, the orifice having a diameter smaller than that of the flow channel at the upstream end, the flow channel including a first portion downstream of the orifice plate that tapers inwardly in a downstream direction along the axis toward a second portion of the flow channel, the second portion tapering outwardly along the axis in a downstream direction toward the downstream end.

21. A method of treating a body of liquid comprising:

passing the liquid through a cyclonette that includes a body having an upstream and a downstream end and an internal, unidirectional flow channel extending therethrough along an axis of the body from the upstream end to the downstream end, the body including an orifice plate situated proximate the upstream end of the unidirectional flow channel and having an orifice defined therethough, the orifice having a diameter smaller than that of the flow channel at the upstream end, the body further including an insert situated at the upstream end thereof adjacent the orifice plate, the insert having an opening extending therethrough along the axis to allow for passage of liquid from the upstream end, and through the orifice towards the downstream end of the device.
