Abstract
A nanobubble generator suitable for high water flows, with low energy input, generating liquid flow containing a high volume of gas in the form of nanobubbles. The nanobubble generator includes a plurality of mixing tubes between an inlet manifold and an outlet manifold having internal helical guides configured to condition the two-phase fluid flow to produce a number of certain effects which in combination facilitate nanobubble generation. This provides a nanobubble generator that at high water flows has high gas to liquid transfer efficiency and low head loss, is simple, inexpensive and easy to maintain.
Claims43
A nanobubble generator comprising:
- a. an inlet manifold;
- b. an outlet manifold;
- C. a plurality of mixing tubes between the inlet manifold and outlet manifold having internal helical guides configured to produce nanobubbles in a liquid passing through the nanobubble generator;
- and
- d. one or more gas injection ports near the inlets to the mixing tubes, wherein the mixing tubes follow a twisted path from the inlet manifold to the outlet manifold,
- wherein the total internal cross-sectional area varies by no more than 30% along the length of the mixing tubes and outlet manifold.
