Filed: 1937-06-07
Abstract: 496,889. Treating liquids with gases. MULLER, P. H. June 7, 1937, No. 15731. [Class 55 (ii)] [Also in Group XIII] A cooling - tower stack comprises horizontal rods disposed above one another at intervals of <3>/16 -< 9/>16in. in groups lying in vertical planes the rods being not more than #-¥in. high, or the rod groups may be arranged slightly inclined to the vertical, the rods being of parallelogram form in cross-section with horizontal upper and lower faces. Each group may be bound by wires 7 hooked over inclined boards 5 and an assembly of groups may have a series of rods 10 at right-angles to and at the ends of the main rods to prevent water accumulating at the ends of rods not strictly horizontal from falling directly to the ground. A modification provides groups of rods at right angles to the main groups and alternating therewith so that the stack comprises superposed horizontal layers of rods running crooswise to adjacent layers. Grates of vertical bendproof boards 14, 17, are disposed at the top and bottom and secured to uprights 13 at the corners. Water is distributed by a plate 21 and after trickling over the rods is directed by boards 22 .. 24 into channels 25. To avoid excessive expansion of the stack taller and shorter rods may alternate in each layer and also in the vertical plane whereby swelling is compensated for by bending of the rods ; or equal sized rods half with deep and half with shallow grooves or each with alternating deep and shallow grooves produce a similar effect. Each upright 13 may support the of four stack units, or four uprights may be provided for each unit which may be withdrawn as a whole. Another withdrawable unit has a single central upright and may be isolated from others by temporary walls placed round it and roofed over. The upper grate of a unit may be loaded with weights and allowed to rise and fall with alteration in the shape of the rods.
