Fluid mixing apparatus

Claim 1

An apparatus to be used for mixing two fluids and injecting the resulting mixture into a third fluid which comprises: a. an inner tube and an outer tube concentrically arranged to form an annular volume located between the inside of the outer tube and the outside of the inner tube, said inner and outer tubes having one end of each adjacent to each other, said ends being sealed; b. outlet port means located on said outer tube positioned adjacent to said sealed end of said outer tube; c. outlet port means located on said inner tube, said port means positioned on said inner tube a longitudinal distance from said sealed end of said inner tube so that said port means on said inner tube is farther from the sealed end of said outer tube when measured longitudinally on said outer tube than said port means on said outer tube is from its said sealed end whereby to form an annular mixing chamber between said respective outlet port means; d. first fluid inlet means connected to said inner tube to allow a first fluid to be passed into said inner tube and through said inner tube port means; e. second fluid inlet means connected to said outer tube to allow a second fluid to be passed into said outer tube through said annular volume and through said outer tube port means, said outer and inner tube configuration being connected to a circulation vessel means to allow said outer tube port means to be in communication with a third fluid to be passed through said circulation vessel means; whereby a first fluid can pass into said inner tube through said inlet means out of said inner tube via said port means and can be contacted and mixed in said annular volume with a second fluid which can flow through said annular volume, the resultant mixture can be passed through said outer tube port into said circulation vessel to contact a third fluid which can pass through said circulation vessel means.

Claim 2

An apparatus to be used for mixing two fluids and injecting the resulting mixture into a third fluid which comprises: a. an inner tube and an outer tube concentrically arranged to form an annular volume located between the inside of the outer tube and the outside of the inner tube, said inner and outer tubes having one end of each adjacent to each other, said ends being sealed; b. outlet port means located on said outer tube positioned adjacent to said sealed end of said outer tube; c. outlet port means located on said inner tube, said port means positioned on said inner tube a longitudinal distance from said sealed end of said inner tube so that said port means on said inner tube is farther from the sealed end of said outer tube when measured longitudinally on said outer tube than said port means on said outer tube is from its said sealed end whereby to form an annular mixing chamber between said respective outlet port means; d. first fluid inlet means connected to said inner tube to allow a first fluid to be passed into said inner tube and through said inner tube port means; e. second fluid inlet means connected to said outer tube to allow a second fluid to be passed into said outer tube through said annular volume and through said outer tube port means, said outer and inner tube configuration being connected to a circulation vessel means to allow said outer tube port means to be in communication with a third fluid to be passed through said circulation vessel means; whereby a first fluid can pass into said inner tube through said inlet means out of said inner tube via said port means and can be contacted and mixed in said annular volume with a second fluid which can flow through said annular volume, the resultant mixture can be passed through said outer tube port into said circulation vessel to contact a third fluid which can pass through said circulation vessel means.

Claim 5

An apparatus for mixing two fluids and injecting the resultant mixture into a third fluid which comprises: a. a circulation vessel means to allow the circulation of a fluid there through; b. an outer fluid transfer tube connected to said circulation vessel means, said tube having one end sealed off with outer tube port means located on said tube adjacent to said sealed end, said tube extending into said circulation vessel to allow said port means to be in communication with an inside of said circulation vessel means; c. fluid inlet means connected to said outer fluid tube to allow the flow of a fluid into said tube through a herein below described annular volume and out of said port means into said circulation vessel; d. an inner fluid transfer tube concentrically located within said outer tube to form an annular volume located between the inside of said outer tube and the outside of said inner tube, said inner tube having one end sealed off, with the respective sealed ends of said inner and outer tubes adjacently positioned, port means located on said inner tube so that when proceeding along a longitudinal axis of said concentric tubes from the sealed end of the outer tube the port means of said outer tube are closer to its said end than the port means of said inner tube to thereby provide an annular mixing chamber between said respective port means; e. fluid inlet means connected to saId inner fluid transfer tube to allow the flow of a fluid into said inner fluid transfer tube and through said inner tube port means; whereby a fluid can flow into said inner tube through said port means on said inner tube and be mixed in said annular volume with fluid flowing through said outer tube, the resulting admixture can be passed through said port means on said outer tube to be contacted with a fluid which can circulate through said circulation vessel.

Claim 6

An apparatus for mixing two fluids and injecting the resultant mixture into a third fluid which comprises: a. a circulation vessel means to allow the circulation of a fluid there through; b. an outer fluid transfer tube connected to said circulation vessel means, said tube having one end sealed off with outer tube port means located on said tube adjacent to said sealed end, said tube extending into said circulation vessel to allow said port means to be in communication with an inside of said circulation vessel means; c. fluid inlet means connected to said outer fluid tube to allow the flow of a fluid into said tube through a herein below described annular volume and out of said port means into said circulation vessel; d. an inner fluid transfer tube concentrically located within said outer tube to form an annular volume located between the inside of said outer tube and the outside of said inner tube, said inner tube having one end sealed off, with the respective sealed ends of said inner and outer tubes adjacently positioned, port means located on said inner tube so that when proceeding along a longitudinal axis of said concentric tubes from the sealed end of the outer tube the port means of said outer tube are closer to its said end than the port means of said inner tube to thereby provide an annular mixing chamber between said respective port means; e. fluid inlet means connected to saId inner fluid transfer tube to allow the flow of a fluid into said inner fluid transfer tube and through said inner tube port means; whereby a fluid can flow into said inner tube through said port means on said inner tube and be mixed in said annular volume with fluid flowing through said outer tube, the resulting admixture can be passed through said port means on said outer tube to be contacted with a fluid which can circulate through said circulation vessel.
