Abstract
Abstract A device for putting into contact substances existing in at least two different phases, one of which is a gaseous phase introduced into a cylindrical section for helicoidal flow, a divider extending axially through the cylindrical section having openings for passage of the helicoidal streams therethrough to a bicone, an axial passage for introduction of the other phase into the path for engagement by the helicoidal streams for copulverization.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
195 words
A device for putting into contact substances existing in different phases, at least one of which is a fluid or gaseous phase comprising a housing of circular cross section, an inlet adjacent the outer periphery of the housing for introduction of the fluid or gaseous phase tangentially into the housing for helicoidal flow therein, an axial outlet opening at the center of the housing, said housing having a converging section extending inwardly to said outlet opening, a divergent section extending from the outlet opening to define a bicone between said converging and diverging sections which define a restricted axial passage at the outlet, at least one axial pipe, the outlet of which is at the level of the restricted passage through which at least one of the other phases is introduced for issuance at the restricted passage to be engaged by the helicoidal flow at about the restricted passage, and a cylindrical dividing member which extends axially through the housing intermediate the inlet and outlet, having passages therein for enabling the helicoidal flow of the one phase for enabling passage of the helicoidal flow of the one phase therethrough from the inlet to the outlet.
Claim 2
Independent Claim
195 words
A device for putting into contact substances existing in different phases, at least one of which is a fluid or gaseous phase comprising a housing of circular cross section, an inlet adjacent the outer periphery of the housing for introduction of the fluid or gaseous phase tangentially into the housing for helicoidal flow therein, an axial outlet opening at the center of the housing, said housing having a converging section extending inwardly to said outlet opening, a divergent section extending from the outlet opening to define a bicone between said converging and diverging sections which define a restricted axial passage at the outlet, at least one axial pipe, the outlet of which is at the level of the restricted passage through which at least one of the other phases is introduced for issuance at the restricted passage to be engaged by the helicoidal flow at about the restricted passage, and a cylindrical dividing member which extends axially through the housing intermediate the inlet and outlet, having passages therein for enabling the helicoidal flow of the one phase for enabling passage of the helicoidal flow of the one phase therethrough from the inlet to the outlet.
Claim 3
Dependent Claim
24 words
A device as claimed in claim 1 which includes a double walled jacket about the housing for circulation of a heat exchange fluid therethrough.
Claim 4
Dependent Claim
30 words
A device as claimed in claim 1 which includes a rod extending axially to the outlet opening and dimensioned to correspond more or less to the radius of the opening.
Claim 5
Dependent Claim
19 words
A device as claimed in claim 1 in which the cylindrical dividing member is detachably mounted in the housing.
Claim 6
Dependent Claim
15 words
A device as claimed in claim 1 which includes a venturi coupled with the outlet.
