Jan. 4, 1944. M. 'AURIG DISIN'IEGRATORLIKE DEVICE Filed Aug. 5, 1940 Max 41/1 111 Patented Jan. 4, 1944 Max Aurig, Munich, Germany; vested in Alien Property Custodian the" Appli ation Au ust 5, 1940, Serial N 351,470 In Germany June 4, 19 3 This invention relates to a disintegrator for purifying, cooling and mixing gases.
In the known types of such disintegrators or disintegratorlike devices possessing both rotary and stationary or only rotary concentric annular frames formed of bars the latter comprise angles, flats, ledges and units having the form of a vane or turbine blade. Of all these kinds of bars at present in use, regardless of their relative arrangement, only the front or striking side thereof contacting with the gas and liquid mixture is utilized as a rule for the washing effect. In the course of time incrustations of dust form on the back of the bars which require therefore periodical cleaning or replacement. It has been found that this condition is due to the fact that the bars are surrounded by the washing liquid only incompletely or not at all.
The invention eliminates this drawback by imparting to the bars a drop-shaped section which offers minimum resistance to a flowing medium which, furthermore, surrounds the entire surface thereof, so that the full surface of the bars is utilized for washing, cooling or mixing a gas. This shape of the bars affords, moreover, the added advantage that a rarified air space creating a suction effect cannot form and the power consumption of the device can thus be considerably reduced. Still another advantage is that incrustations cannot form on the surfaces of the bars.
The bars according to the invention may be solid or hollow, but their direction must be adapted to circumferential speed and the speed of travel of the gas while taking into consideration that always the entire circumference is uniformly surrounded by the washing, cooling or mixing liquid. In the most favorable position the longitudinal axis of the drop-shaped section is parallel to the direction of flow of the medium surrounding the body.
The invention is illustrated by way of example in the accompanying drawings, in which Fig. 1 is an elevational view, with parts shown in section, of a standard type of disintegrator gas Washer with'which the present invention is concerned.
Figure 2 shows part of a disintegrator according to the invention provided with a stationary annular frame of bars and rotary frame sections, and
Fig. 3, the use of rotary bars only.
The standard type of disintegrator gas washer, with which the present invention is concerned, is disclosed in Fig. l and include the housing in supported upon a suitable foundation l2 of concrete. or similar'material and constructed to, provide a'plurality of gas inlets I3 which conduct the gas to the interior chamber I4. Suitably journaled upon supports IS on both sides of the housing I0 is an operating shaft IE to which is centrally secured a circular plate I! of fairly large diameter. The washing medium, preferably water, is conducted to the housing ill by means of supply pipes l8 and is discharged from the interior pipe 20, located adjacent the shaft l5 and within the spray cones 2 I. The spray cones comprise cylindrical members having a slightly tapered formation and which are suitably secured to the revolving plate I! concentric with the op erating shaft IS. The washing medium thus discharged within the spray cones 2| is discharged in finely divided form to the interior chamber [4 by means of perforations 22 provided in the cones for the purpose.
The active elements which function to thoroughly mix the washing medium and the gases, both of which are discharged into the interior chamber l4, comprise a plurality of rotating disintegrator bars a, suitably secured at their inner ends to the revolving plate I1, and a plurality of stationary bars b, suitably secured at their outer ends to the plate 25. Both the rotary and stationary bars are secured and arranged in rows concentric to the operating shaft l6 and are disposed so that the gases in traveling outwardly to the outlet 26 pass alternate sets of stationary and rotary bars.
The scrubbing effect is obtained by intimately associating the particles of dust contained in the gas with the washing medium, and the present invention is primarily concerned with the shape or surface contour of the disintegrator bars. Each of the present bars a or b may be solid or hollow, but their contour is such as to ofier minimum resistance to a flowing medium which surrounds the entire surface of the bars, so that the full surfaces of the bars a and b are utilized for washing, cooling or mixing the mediums with which they engage. The shape of the bars a and b are drop-shaped in section, which affords the advantage that a rarified air space creating a suction effect cannot form to the detriment of power consumption. Moreover, such shape aids in preventing the formation of incrustations on the surfaces of the bars.
In the construction shown in Fig. 2 the rotary sections of the frame are formed of bars a and the stationary section of bars b. The direction of motion is indicated by arrows. It will be seen posed of bars having a drop-shaped section toprevent the formation of incrustations thereon, the head of each drop being directed oppositely to the direction of the flowing medium surrounding the bars.

3, A disintegrator gas Washer, having concentric rows of disintegrator bars mounted for rotation in direction opposite to the path of flow of gas, said bars having a drop-shaped section heading angularly in the direction of rotation, and at least one row of stationary bars of like cross-section concentric with one of said rotating rows and adjacent thereto, the heads of the bars in said stationary row being directed oppositely to said rotating bars.
4. A disintegrator gas washer, having'concentric rows of disintegrator bars mounted for rotation in direction opposite to the path of flow of gas, said bars having a drop-shaped section heading angularly in the direction of rotation, and at least one row of stationary bars of like cross-section concentric with one of said rotating rows and adjacent thereto, the heads of the bars in said stationary row being directed oppo sitely to said rotating bars, and the major axis of each said rotating bar being substantially at right angles to the major axis of said stationary ars MAX AURIG.
