Abstract
Disclosed is a system that uses multiple Venturi injectors in series. These Venturi injectors may inject a fluid, such as a gas or a liquid, into the liquid stream passing through the Venturi injectors. The system may include two or more Venturi injectors with an inlet port that receives an inlet liquid stream, a suction port that may passively receive a fluid, such as a gas, and an outlet port that ejects the mixture of liquid and fluid. The Venturi injectors are positioned in series along a liquid conduit, where each downstream Venturi injector is successively larger than the immediately preceding Venturi injector.
Claims18
A system, comprising:
- two or more Venturi injectors positioned in series along a liquid conduit, where each successive Venturi injector of the two or more Venturi injectors in a direction of liquid flow is larger than an immediately preceding Venturi injector of the two or more Venturi injectors;
- each of the two or more Venturi injectors includes a monolithic body forming a fluid passage that is continuous and axially-aligned, and that converges, without interruption, from a motive-liquid inlet directly to a throat of minimum cross-sectional diameter along the fluid passage, and then diverges, without interruption, directly from the throat into a fluid outlet;
- and
- each of the two or more Venturi injectors includes a suction inlet port that extends into the throat transverse to the direction of liquid flow along the fluid passage.
A system, comprising:
- a first Venturi injector and a second Venturi injector positioned in series along a liquid conduit with the second Venturi injector positioned downstream from the first Venturi injector;
- the second Venturi injector is larger than the first Venturi injector;
- each of the first Venturi injector and the second Venturi injector includes a monolithic body forming a fluid passage that is continuous and axially-aligned, and that converges, without interruption, from a motive-liquid inlet directly to a throat of minimum cross-sectional diameter along the fluid passage, and then diverges, without interruption, directly from the throat into a fluid outlet;
- and
- each of the first Venturi injector and the second Venturi injector includes a suction inlet port that extends into the throat transverse to a direction of liquid flow along the fluid passage.
A wastewater treatment system, comprising:
- a first Venturi injector and a second Venturi injector positioned in series along a wastewater conduit with the second Venturi injector positioned downstream from the first Venturi injector, the first Venturi injector and the second Venturi injector are structured and positioned relative to the wastewater conduit, to inject air bubbles into a wastewater stream within the wastewater conduit;
- the second Venturi injector is larger than the first Venturi injector;
- each of the first Venturi injector and the second Venturi injector includes a monolithic body forming a fluid passage that is continuous and axially-aligned, and that converges, without interruption, from a motive-liquid inlet directly to a throat of minimum cross-sectional diameter along the fluid passage, and then diverges, without interruption, directly from the throat into a fluid outlet;
- and
- each of the first Venturi injector and the second Venturi injector includes a suction inlet port that extends into the throat transverse to a direction of liquid flow along the fluid passage.
