Abstract
Abstract A device in which a gas and liquid mixture is introduced into a distribution chamber through an inlet opening at one side thereof the opposite side being in communication with a plurality of tubes for receiving the gas and liquid mixture; a baffle in said distribution chamber extending substantially perpendicularly to the direction of flow of the gas and liquid mixture forming a narrow passageway in which the mixture flows radially outwards along the inlet opening side and radially inwards along the tube side.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A device for distributing a homogeneous gas and liquid mixture to a plurality of outlet tubes comprising: a. a distribution chamber having spaced inlet and outlet walls and end walls; b. an inlet passage having an opening located substantially centrally in said inlet wall, and inlet passage having a restricted portion; c. the outlet wall having means for passing the gas and liquid mixture into said tubes, and; d. a solid stationary baffle spaced between said walls substantially perpendicular to the direction of flow of said gas and liquid mixture through said inlet opening, said baffle providing a confronting face projecting radially outwardly from said direction of flow a diStance substantially greater than the maximum width of said inlet opening to define a flow space area extending radially from the inlet opening about said baffle whereby flow through said chamber is directed radially outwardly and around said baffle to reach said means for passing the gas and liquid mixture into said tubes.
Claim 2
Independent Claim
162 words
A device for distributing a homogeneous gas and liquid mixture to a plurality of outlet tubes comprising: a. a distribution chamber having spaced inlet and outlet walls and end walls; b. an inlet passage having an opening located substantially centrally in said inlet wall, and inlet passage having a restricted portion; c. the outlet wall having means for passing the gas and liquid mixture into said tubes, and; d. a solid stationary baffle spaced between said walls substantially perpendicular to the direction of flow of said gas and liquid mixture through said inlet opening, said baffle providing a confronting face projecting radially outwardly from said direction of flow a diStance substantially greater than the maximum width of said inlet opening to define a flow space area extending radially from the inlet opening about said baffle whereby flow through said chamber is directed radially outwardly and around said baffle to reach said means for passing the gas and liquid mixture into said tubes.
Claim 3
Dependent Claim
29 words
A device according to claim 1 in which the baffle is spaced between the walls of said distribution chamber a distance effective to produce a substantially constant flow velocity.
Claim 4
Dependent Claim
21 words
A device according to claim 1, in which the inlet wall of the distribution chamber has a substantially conically shaped portion.
Claim 5
Dependent Claim
19 words
A device according to claim 1, in which guide vanes are provided between said baffle and said inlet wall.
Claim 6
Dependent Claim
22 words
A device according to claim 1, in which said outlet wall is provided with openings which are substantially narrower than said tubes.
Claim 7
Dependent Claim
15 words
A device according to claim 1, in which said outlet wall comprises a porous plate.
Claim 8
Dependent Claim
15 words
A device according to claim 1, in which said inlet passage comprises a restricted portion.
