Abstract

Abstract A compact and efficient separator for removing both entrained bubbles and dissolved gases from fluid. Fluid containing gases is introduced tangentially into a vortex flow chamber which is disposed at the suction-side of a pump. The fluid, which is stripped of gaseous contaminants, flows out of the vortex flow chamber while gas-rich fluid collected near center of the chamber passes into a gas removal pipe which is communicated to a suction device.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 154 words
A suction system gas separator device for removing both entrained bubbles and dissolved gases from fluids, comprising: a pump having a suction-side pipe and an outlet pipe; a vortex flow chamber disposed at said suction-side pipe of said pump; fluid introduction means for introducing fluid into said chamber in a tangential direction of said chamber; a gas removal pipe extending into said chamber and disposed substantially at an axial center of said chamber, a plurality of small pores being formed in said gas removal pipe for allowing gas-rich fluid to pass therethrough; a suction device connected with said gas removal pipe, said suction device creating a reduction pressure condition; a main fluid outlet passage means connected to said suction-side pipe of said pump for passing fluid stripped of gaseous contaminants from said chamber to said pump; and fluid outlet passage means of said suction device for discharging gas-rich fluid from said gas removal pipe.
Claim 2
Dependent Claim 154 words
A suction system gas separator device for removing both entrained bubbles and dissolved gases from fluids, comprising: a pump having a suction-side pipe and an outlet pipe; a vortex flow chamber disposed at said suction-side pipe of said pump; fluid introduction means for introducing fluid into said chamber in a tangential direction of said chamber; a gas removal pipe extending into said chamber and disposed substantially at an axial center of said chamber, a plurality of small pores being formed in said gas removal pipe for allowing gas-rich fluid to pass therethrough; a suction device connected with said gas removal pipe, said suction device creating a reduction pressure condition; a main fluid outlet passage means connected to said suction-side pipe of said pump for passing fluid stripped of gaseous contaminants from said chamber to said pump; and fluid outlet passage means of said suction device for discharging gas-rich fluid from said gas removal pipe.
Claim 3
Dependent Claim 25 words
The separator device of claim 1, wherein the diameter of said vortex flow chamber is reduced in a downstream direction in said vortex flow chamber.
Claim 4
Dependent Claim 23 words
The separator device of claim 1, wherein said suction device is operated by the fluid discharged from said outlet pipe of said pump.
Claim 5
Dependent Claim 33 words
The separator device of claim 1, wherein the upper wall defining said vortex flow chamber is opened and said upper wall is overlapped by another cone wall fixed to said gas removal pipe.
Claim 6
Dependent Claim 23 words
The separator device of claim 1, further comprising a screen covering an inlet opening of said introduction means for filtration of coarse solids.
Claim 7
Dependent Claim 21 words
The separator device of claim 1, further comprising a check valve disposed in said outlet passage means of said suction device.
Claim 8
Dependent Claim 13 words
The separator device of claim 1, wherein said suction device is an aspirator.
Claim 9
Dependent Claim 39 words
The separator device of claim 7, wherein said aspirator is connected to said outlet pipe of said pump so as to provide a motive fluid for said aspirator to thereby entrain said gas-rich fluid from said gas removal pipe.
