Method of generating micro and nano bubbles in a fluid

摘要

A method according to the present invention for generating micro and nano bubbles of substantially five microns or less in a fluid, is accomplished by injecting a gas through a gas feed conduit into a liquid stream to create a combined flow of gas and liquid, the gas being up to 15 volume percent at STP of the liquid being streamed. This combined flow is contained within a closed container having at least one primary zone and a secondary zone. The combined flow is pressurizing within the closed container primary zone(s) and the pressurized combined flow is maintained at a predetermined first fluid pressure level of substantially between 100 and 150 PSIG within the closed container primary zone(s). Then the pressurized combined flow is directed from the closed container primary zone(s) to the closed container secondary zone through a plate/disk(s) having one or more orifices/ports restricting the combined flow through the orifice/port(s). A predetermined second fluid pressure level within the closed container secondary zone(s) is within a pressure differential range of substantially 60 percent of the combined flow within the closed container primary zone.

1. A method for generating micro and nano bubbles of substantially five microns or less in a fluid flow, comprising the steps of:
injecting a gas through a gas feed conduit into a liquid stream conduit to create a combined flow of gas and liquid where said gas can be up to 15 volume percent at STP of said liquid being streamed; directing said combined flow through an inlet into a closed container, wherein said closed container includes a primary zone and a secondary zone; pressurizing said combined flow within said closed container primary zone and maintaining said pressurized combined flow to a predetermined first fluid pressure level of substantially between 100 and 150 PSIG within said closed container primary zone; directing said pressurized combined flow from said closed container primary zone to said closed container secondary zone through a plate/disk having one or more orifices/ports restricting flow of said combined flow through said orifice/port(s); and measuring and maintaining a predetermined second fluid pressure level within said closed container secondary zone within a pressure differential range of substantially 60 percent of said combined flow within said closed container primary zone, with a backpressure regulator mounted to and in communication with a combined flow outlet conduit, where said combined flow outlet conduit is mounted to said closed container secondary zone, to thereby generate micro and nano bubbles in said combined flow downstream of said backpressure regulator.
