Abstract
A method and apparatus for the aeration of liquids utilizing the injection of gas bubbles is disclosed. The method includes flowing the liquid through a horizontal portion (36), then to a venturi air injector (10), around a bend (38), down a vertical portion (40) and into a pressure vessel (14). Inside the pressure vessel (14) the gas is made to flow through a restriction whereby the gas bubbles pass more quickly through the restriction and pneumatically accelerate the liquid.
Claims
1. A method of aeration of liquids, comprising the steps of: injecting a gas into a flowing liquid stream thereby forming a plurality of gas bubbles; and directing the liquid stream through a restriction at an impaction target positioned in a pressure vessel whereby the gas bubbles pass upward more quickly through the restriction and pneumatically accelerate the liquid.
2. A method of aeration of liquids as defined in Claim 1, the liquid stream being directed at an impactiύn target after gas injection thereby creating a pneumatic hammering effect.
3. A method of aeration of liquids as defined in Claim 1, the liquid stream being directed after gas injection through a conduit having a bend, such that small. gas bubbles adhere to the wall of the conduit in the vicinity of the bend and amalgamate to form larger bubbles substantially consistent in size prior to being swept by the liquid stream through the restriction.
4. A method of aeration of liquids as defined in Claim 3, the restriction being substantially the same size as the bubbles. 31
5. A method of aeration of liquids as defined in Claim 1, the liquid stream being directed downwardly through a vertically aligned conduit prior to flowing through the restriction, such that a spatial separation of the bubbles occurs.
6. A method of aeration of liquids as defined in Claim 1, the restriction being positioned in a pressure vessel.
7. A method of aeration of liquids as defined in Claim 2, the impaction target being at the top of a pressure vessel such that the bouyancy of the air bubbles results in an acceleration of the liquid stream prior to impacting upon the target.
8. A method of aeration of liquids as defined in Claim 7, the pressure vessel being a tower such that the liquid stream strikes the impaction target and then by force of gravity cascades through the gas in the pressure vessel to further impact upon liquidation accumulated in the pressure vessel.
9. A method of aeration of liquids as defined in Claim 8, a plate including a plurality of openings being spaced from the top of the pressure vessel such that the liquid stream impacts upon the plate and passes through the openings in the plate to further impact upon licruid accumulated in the pressure vessel.
10. A method of aeration of liquids as defined in Claim 1, the restriction being a gap having a generally cylindrical peripheral edge.
33
11. A method of aeration of liquids, comprising the steps of: injecting a gas into a flowing liquid stream thereby forming a plurality of gas bubbles; and directing the liquid stream through a restriction at an impaction target positioned in a pressure vessel whereby the gas bubbles pass upward more quickly through the restriction, creating a pneumatic acceleration and hammering effect against the impaction target.
34
12. A method of aeration of liquids, comprising the steps of: injecting a gas into a flowing liquid stream thereby forming a plurality of gas bubbles; directing the liquid stream through a conduit having a bend, such that small gas bubbles adhere to the wall of the conduit in the vicinity of the bend and amalgamate to form larger bubbles substantially consistent in size prior to being swept by the liquid stream; and directing the liquid stream through a restriction at an impaction target positioned in a pressure vessel whereby the gas bubbles pass more quickly through the restriction pneumatically accelerating the liquid and creating a hammering effect against the impaction target.
35
13. A method of aeration of liquids, comprising the steps of: injecting a gas into a flowing liquid stream thereby forming a plurality of gas bubbles; directing the liquid stream through a conduit having a bend, such that small gas bubbles adhere to the wall of the conduit in the vicinity of the bend and amalgamate to form larger bubbles substantially consistent in size prior to being swept by the liquid stream; directing the liquid stream downwardly through a vertically aligned conduit such that a spatial separation of the bubbles occurs; and directing the liquid stream through a restriction at an impaction target positioned in a pressure vessel whereby the gas bubbles pass more quickly through the restriction, creating a pneumatic acceleration and hammering effect against the impaction target.
36
14. A method of aeration of liquids, comprising the steps of: injecting a gas into a flowing liquid stream thereby forming a plurality of gas bubbles; directing the liquid stream through a conduit having a bend, such that small gas bubbles adhere to the wall of the conduit in the vicinity of the bend and amalgamate to form larger bubbles substantially consistent in size prior to being swept by the liquid stream; directing the liquid stream downwardly through a vertically aligned conduit, such that a spatial separation of the bubbles occurs; and directing the liquid stream through a restriction at an impaction target positioned in a pressure vessel whereby the gas bubbles pass more quickly through the restriction, creating a pneumatic acceleration and hammering effect against the impaction target, the impaction target being at the top of a tower-like pressure vessel such that the liquid stream impacts upon the target and then by force of gravity cascades through the gas in the pressure vessel to further impact upon a plate with a plurality of openings spaced from the top of the pressure vessel and passes through the openings in the plate and by force of gravity cascades through the gas in the pressure vessel to further impact upon liquid accumulated in the pressure vessel.
D SHEET ARTiCL- 37
15. An apparatus for aeration as defined in claim 1, of liquids, comprising a tower-like pressure vessel having a top, a bottom, an interior, an exterior, an inlet and an outlet, the inlet and the outlet to the vessel being adjacent the bottom, the vessel having a cylindrical conduit in the interior which extends substantially vertically, the interior conduit having a first and communicating with inlet and a second and disposed immediately adjacent the top thereby forming a gap which serves as a flow restriction.
