Abstract: 151.,038. Pease, E. L. April 14, 1919. Freely - flowing material mixed in conduits.-Relates to means for subdividing fluid into a number of streams that can be intimately mixed together and brought into close contact with the subdividing means, or into intimate contact with another fluid, or directly subjected to the action of another fluid to produce an intimate mixture of combustible fluids for heating, washing, purifying, filtering, or cooling purposes. One or more perforated conduits for fluids are provided with subdividing means comprising a number of bars or sheets arranged in parallel or substantially parallel planes and assembled closely together so that parts of their adjacent surfaces are in contact and other parts, in contact with the conduit or conduits, are separated so as to provide narrow or thin channels to divide the fluid into a number of narrow or thin flat separated streams. As shown in Fig. 1, two sets of thin bars a of metal or refractory material are arranged across the top or one end of a conduit or vessel b, the bars in one set being arranged between those in the other set and crossing them so that the upper and lower angles between the two sets are obtuse angles. The bars are in close contact with each other at their central portions, where they are traversed by a rod c, and at each side or end of the 'bars is an horizontal tube d forming with the diverging ends of the bars a longitudinal space e of approximately triangular shape in cross-section. Jets of fluid passing through apertures f in the tubes d mix with subdivided streams of fluid flowing through the narrow spaces between the outer end portions of the bars a. This device may be disposed at the top of a gas-producer to mix the gas coming therefrom with air to form a combustible mixture that can be burnt above the bars a to heat a boiler-furnace &c. One set of bars may be fixed on the rod c, so that by turning the rod any dust on the bars can be dislodged and the burner system closed. Fig. 3 shows a single tube d associated with two sets of bars a diverging from a supporting-bar c at one end; and Fig. 4 shows two sets of bars a supported at one end and disposed at each side of a central tube d. In another arrangement, Figs. 5 and 6, a series of vertical sheets or strips h disposed at right-angles to two perforated horizontal tubes d are in close contact with one another sideways along the centre line between the tubes, but are alternately deflected from the horizontal so that their points of contact with the tubes at one end are under and at the other end above a perforation in the tubes. The sheets, by their shape and depth or by suitable notching and perforating, permit of the passage of fluid from their under to their upper edges. The sheets may be of uniform width for part of their length at one end, and of taper or triangular shape at the other end, with notches i in alternate sheets. Or the sheets h, Fig. 7, may be triangular and be reversely arranged so as to leave passages between their end portions adjacent the tubes d. The arrangements described may be applied to the upper portion of a conduit or tower for washing, purifying, or cooling gas rising therethrough, water or other suitable washing, purifying, or cooling liquid being supplied to the tubes.
