Enhanced capacity, reduced turbulence, trough-type liquid collector trays

摘要

Liquid collector trays (5) are disclosed for use in vertical towers (7) in which vapor (9) moves upward and liquid (11) moves downward. The liquid collector trays (5) employ elongated plates (13) which in certain embodiments include a primary liquid collector trough (15) and a secondary liquid collector trough (17). In other embodiments, the primary liquid collector troughs (15) of adjacent plates (13) are aligned so as to form elongated, inwardly-tapering entrance channels (29) which are free of sharp corners. In further embodiments, when the liquid collector tray (5) is in its operative orientation and is viewed from above, each plate (13) includes first and second concave surfaces (31, 33), which collect liquid, and third and fourth convex surfaces (35, 37), which are adjacent to the first and second concave surfaces (31, 33) and serve to mechanically stabilize the plate (13).

主权项

1. A liquid collector tray for use in a vertical tower in which vapor moves upward and liquid moves downward, the liquid collector tray comprising a plurality of elongated plates arranged adjacent to each other, each elongated plate comprising:
(a) a primary liquid collector trough; (b) a secondary liquid collector trough; and (c) a wall located between the primary liquid collector trough and the secondary liquid collector trough; (d) a mechanical stabilizer located between the wall and the secondary liquid collector trough; wherein when the liquid collector tray is in an operative orientation for the liquid collector tray:
(i) the primary liquid collector trough is vertically below the secondary liquid collector trough;(ii) for each elongated plate, the primary liquid collector trough is horizontally offset from the secondary liquid collector trough(iii) the primary liquid collector trough having a concave surface viewed from above;(iv) the secondary liquid collector trough having a concave surface viewed from above;(v) the mechanical stabilizer having a convex surface viewed from above; and (e) wherein at least one of the elongated plates further comprises a mechanical stabilizer rib formed along the convex surface of the mechanical stabilizer located between the wall of the elongated plate and the secondary liquid collector trough of the elongated plate.
