Electrolytic cell having a transition duct outlet

摘要

An electrolytic cell is provided. The cell includes a housing having a liquid inlet and a liquid outlet outlet, an anode and a cathode positioned within the housing and defining a reaction chamber therebetween, and a liquid flow path, from the liquid inlet to the liquid outlet, which passes through the reaction chamber. A transition duct is positioned at the liquid outlet and has a duct inlet, a duct outlet and a transition section along which internal side walls of the transition section converge along the liquid flow path to define a smooth transition from a first cross-sectional area to a second cross-sectional area of the transition duct. The first cross-sectional area is at least two times greater than the second cross sectional area.

1. An electrolytic cell comprising:
a housing comprising a liquid inlet and a liquid outlet; an anode and a cathode positioned within the housing and defining a reaction chamber therebetween; a liquid flow path, from the liquid inlet to the liquid outlet, which passes through the reaction chamber; and a transition duct at the liquid outlet and comprising:
a duct inlet, which has a generally rectangular cross-section in a cross-sectional plane that is transverse to a direction of fluid flow through the duct inlet;a duct outlet, which has an oval or elliptical shape; anda transition section along which internal side walls of the transition section converge along the liquid flow path to define a smooth transition from a first cross-sectional area to a second cross-sectional area of the transition duct, wherein the first cross-sectional area is at least two times greater than the second cross sectional area, wherein the transition section has an internal channel that transitions along the transition section from the generally rectangular shape at a location of the first cross-sectional area to the oval or elliptical shape at a location of the second cross-sectional area; anda rectangular curved section extending between the duct inlet and the transition section, along which the liquid flow path through the transition duct transitions from a first direction at the duct inlet to a second direction at the duct outlet, which is perpendicular to the first direction, the rectangular curved section comprising:
the generally rectangular cross-section with flat edges and curved corners, perpendicular to the liquid flow path; andcurved internal, opposing surfaces along at least one plane that is parallel to the liquid flow path and along which the liquid flow path transitions from the first direction to the second direction.
