Claims
- 1. An improved liquid distributor for a process column of the type wherein a plurality of distributor troughs receives liquid flow from a liquid source for establishing a liquid level within said troughs and distributing said flow downwardly to packing beds therebeneath, said improvement comprising:
- a primary flow channel disposed within at least one of said distributor troughs in general axial alignment therewith, substantially above the liquid level therein and positioned in flow communication with said liquid source;
- said primary flow channel being secured relative to said distributor trough in which it is disposed, substantially above the liquid level therein and constructed for disseminating flow above said liquid level and into said trough from said liquid source for enhanced uniformity at relatively high mass flow volume therealong, and said primary flow channel being integrally formed with said distributor trough and said distributor further including at least one stilling plate secured to and depending from said flow channel into said trough.
- 2. An improved method of liquid flow distribution in a packed tower of the type wherein liquid flow is dispersed from a liquid source through a plurality of distributor troughs having a liquid level established therein onto a packing bed disposed therebeneath, wherein said improvement comprises the steps of:
- forming a primary flow channel adapted for being received in at least one of said distributor troughs in general axial alignment therewith;
- disposing said primary flow channel in said distributor trough in which it is disposed in an exposed position substantially above the liquid level therein;
- securing said primary flow channel in said distributor trough substantially above the liquid level and in flow communication with said liquid source for the distribution of liquid flow therein at relatively high mass flow volumes;
- constructing at least one stilling plate for securement to said flow channel; and
- affixing said plate to said channel for depending therefrom and into said trough.
- 3. A liquid distribution system for process columns comprising:
- a primary liquid supply;
- a plurality of flow distribution troughs disposed in flow communication with said supply for establishing a liquid level therein;
- a plurality of primary flow channels disposed upon said troughs, substantially above the liquid level therein and in axial alignment and in flow communication therewith; and
- means coupling said primary flow channels to said fluid supply for permitting said fluid flow through said primary flow channels into said troughs therebeneath for maintaining the uniform liquid level therein;
- said troughs comprising distributor troughs positioned beneath and in flow communication with said primary liquid supply through said primary flow channel, said distributor troughs having said primary flow channels secured thereto beneath said primary liquid supply; and
- said distributor troughs further being positioned beneath said primary liquid supply to receive partial liquid flow directly therefrom and with said primary flow channels secured beneath said primary liquid supply to also receive partial liquid flow therefrom for distributor to said distributor trough at at least one point distant from said primary liquid supply.
