Abstract 949,529. Gas-liquid contact columns. FRITZ W. GLITSCH & SONS Inc. Feb. 21, 1962 [March 3, 1961], No. 6809/62. Heading B1R. A grid element for vapour-liquid contact apparatus comprises a structural member including a horizontal portion, formed with a plurality of spaced openings therein constituting upright passages, characterized in that the member is provided with a plurality of spaced reinforcing ribs extending from the horizontal portion, and the openings in the horizontal portion extend into the ribs and thus form horizontal passages therethrough of smaller area than the upright passages. The ribs alternately extend in opposite directions from the horizontal portion. Preferably the horizontal passages are more than one-tenth and less than one-half of the combined area of the upright passages. Fig. 5 shows a grid section 14 formed initially from a flat sheet having a multiplicity of relatively large openings 15 of any desired configuration formed in closely spaced relationship. The section is bent longitudinally upon itself to form a plurality of upright, reinforcing, parallel ribs 16 and 17 which are connected by horizontal elements or webs 18. The openings are of such size that opposed portions or segments 19 and 20 extend into the legs 16 and 17 forming horizontal passages. Each grid section may be constructed of a plurality of elongate narrow members 21, or may be a one-piece construction. The angles between adjacent layers may be 30 degrees, 45 degrees, 60 degrees, or 90 degrees.
A GRID FOR VAPOR-LIQUID CONTACT APPARATUS INCLUDING A PLURALITY OF SUPERIMPOSED LAYERS, EACH LAYER INCLUDING A SUBSTANTIALLY HORIZONTAL PORTION AND A PLURALITY OF SPACED REINFORCING RIBS UPSTANDING AND DEPENDING FROM THE SUBSTANTIALLY HORIZONTAL PORTION, THE DEPENDING RIBS OF EACH LAYER RESTING ON THE UPSTANDING RIBS OF THE UNDERLYING LAYER WHEREBY THE SUBSTANTIALLY HORIZONTAL PORTIONS OF ADJACENT LAYERS ARE SPACED APART, SAID SUBSTANTIALLY HORIZONTAL PORTIONS HAVING A PLURALITY OF CLOSELY SPACED OPENINGS OF RELATIVELY LARGE SIZE TO PROVIDE UPRIGH PASSAGES THROUGH THE LAYERS, THE OPENINGS BEING FORMED BETWEEN THE RIBS WITH SMALL AREAS THEREOF EXTENDING INTO THE INNER PORTIONS OF SAID RIBS TO PROVIDE SUBSTANTIALLY HORIZONTAL PASSAGES INTERMEDIATE THE UPPER AND LOWER MARGINS OF EACH LAYER OF LESS AREA THAN THE UPRIGHT PASSAGES, SAID RIBS HAVING CONTINUOUS OUTER PORTIONS TO REINFORCE SAID LAYERS.
