Sonic energy fluid degassing unit

Claim 2

A sonic energy fluid degassing unit, comprising a. a conduit through which fluid containing entrained gases flows; b. a sonic energy transducer assembly having at least two spaced apart sonic energy generators each having a different frequency, said different frequency decreasing from one said sonic energy generator to the next in the direction of said fluid flow, connected to the conduit for applying sonic vibration to the passing fluid stream in the conduit to induce growth of gas bubbles of entrained gases therein; c. at least one venturi located in said conduit including means for introducing foreign matter into said entrained gas fluid; and d. gas bubble removal means for removing the gas bubbles from the fluid stream.

Claim 3

The sonic energy fluid degassing unit as set forth in claim 1, wherein: a. the sonic energy generating means includes a conduit through which the fluid passes, b. the conduit has a plurality of outwardly radially extending ribs integrally connected with the conduit, and c. transducer elements are mounted on said ribs for imparting sonic energy vibrations to the ribs.

Claim 4

The apparatus of claim 1 wherein each said sonic energy generator encountered by said entrained gas fluid flow, following said at least one venturi, magnifies said foreign gas bubbles introduced at said venturi thereby dissolving the foreign gas into the entrained gas fluid.

Claim 5

The sonic energy fluid degassing unit as set forth in claim 1, wherein said sonic energy transducer assembly includes: a. a first stage sonic energy generator for producing and imparting a relatively high frequency vibration to the passing fluid stream to generate gas bubble nuclei, b. means, communicating with said conduit, for introducing foreign gaseous or other material into the gas entrained fluid; and c. a second stage sonic energy generator for producing and imparting lower frequency energy vibrations to the passing fluid than those of the first stage to thereby magnify the gas bubble nuclei previously generated by the first stage and to magnify and dissolve gas bubbles introduced by said foreign material introducing means.

Claim 6

The sonic energy fluid degassing unit as set forth in claim 4, wherein: a. the first stage produces an ultrasonic acoustic vibration frequency, and b. the second stage produces a sonic acoustic vibration frequency.

Claim 7

The apparatus of claim 4 further including means for providing a head upstream from said venturi to compensate for the water pressure lost by said fluid when passing through said venturi.

Claim 8

The sonic energy fluid degassing unit as set forth in claim 4 or 5, wherein: a. the first stage contains piezoelectric transducer means for imparting sonic vibrations to the passing fluid, and b. the second stage contains magnetostrictive transducer means for imparting sonic vibrations to the passing fluid.

Claim 9

The sonic energy fluid degassing unit as set forth in claim 7, wherein: a. the higher frequency of the first stage is approximately six times greater than the lower frequency of the second stage.

Claim 10

The sonic energy fluid degassing unit as set forth in claim 8, wherein: a. the first stage produces an acoustic vibration frequency of approximately 53 Khz, and b. the second stage produces a frequency of approximately 8 Khz.

Claim 11

The sonic energy fluid degassing unit as set forth in claim 1, 4, or 5 wherein: said at least one venturi is placed between the two spaced sonic generators for permitting addition of extra chemicals to the passing fluid stream.

Claim 12

The apparatus of claim 1 wherein the first of said at least two sonic energy generators encountered by said fluid generates gas bubble nuclei.

Claim 13

The apparatus of claim 11 wherein all but the first of said at least two sonic energy generators magnify said gas bubble nuclei within said fluid.

Claim 14

The sonic energy fluid degassing unit as set forth in claims 1, 4, 5, 11, 12 or 3 wherein: a. the gas bubble removal means is a gas removal siphon assembly having a central enlarged section which is disposed at an elevation higher than the sonic energy generating means.

Claim 15

The sonic energy fluid degassing unit as set forth in claims 1, 4, 5, 11, 12 or 3 wherein: a. the sonic energy generating means produces a standing wave pattern within the passing fluid.

Claim 17

The sonic energy fluid degassing unit as set forth in claims 1, 11, 12, or 3 wherein: a. the gas bubble removal means is an asonic siphon which has a central section of greater cross-sectional area than the fluid passages of the sonic energy generating means and is disposed at a higher elevation, and b. air vacuum pump means is connected to the central section of the siphon to extract bubbles from the passing fluid.

Claim 18

The sonic energy fluid degassing unit as set forth in claim 16, wherein: a. the asonic siphon assembly central section contains a baffle section.

Claim 19

The sonic energy fluid degassing unit as set forth in claims 4, 5, 11, 12 or 3 wherein: a. the sonic energy generating means produces a standing wave pattern within the passing fluid, and b. the sonic energy generators include a cylindrical shell through which the fluid is passed.
