Patented Feb. 24, 1914.
' Application filed Iuly15, 1913. Serial No. 7 79,098.
To all whom it. may concern:
I Be it known that I, HANS EDUARD THEI- SEN, citizen of the United Statesof America, residing at Munich, in the Kingdom of Bavaria, Germany, have invented certain. new and useful Improvements in Gas-Washing Apparatus, of which'thefollowing is a specificationl This invention relates to gas washlng apparatus of the type wherein a rotary fan is used within a easing into which the gas and aliquid are introduced so that they are subjected to centrifugal action by the fan. The interior of the casing, wherein the fan I, is rotatably mounted, is formed as a substantially annular chamber gradually increasing in diameter in the direction, of the outlet 0 said chamber. In the apparatus of this type heretofore designed thegas and the particles of liquid are flun by the fan against the inner surface of to casing. The efii'ciency of apparatus of this class depends on the degree in which the gas and the liquid are brought into contact with each other, and
the object of my invention is to provide means whereby the contact is increased.
To this end I arrange, between the cir- I cumferenee of the fan and the casing, a
' bafile or baflies against which the liquid and the gas are flung, and bywhich they are more or less deflected, sozis to produce a more intimate mixture of the particles of liquid and gas.
The invention is illustrated in the accompanying drawing, in which Figures 1 and 2 show one embodiment thereof, Fig. '1 being a cross-section of the apparatus, and Fig. 2
a" side elevation.- 1 Figs. 3 to 7 are crosssections illustrating modifications within the scope. of the invention.
In all forms of the invention, the chamber wherein the fan rotates is of substantially annular form gradually increasin in diameter in the direction of the outlet of the chamber. Figs. 3 to 7 being but fragmentary views of the device, the form of the chamber does not there appear.
Referring in the firstinstance to the construction shown in Figs. 1 and 2, a dcsignates the rotary fan, and b the vanes thereof, the passages between the vanes beingclosed at the sides. The fan is arranged in a casing 0, water being 1ntroduced by means of pipes (Z ,wh1ch have discharge orifices within the inner circumference of the ring of vsnesl The gas flows into the casing and through the fan in the manner indi= cated by the arrows in Fig. 1. The passage around the fan, within the casing, rad
ually increases in cross-section, tower the outlet, as best shown in 2. Within this passage a baiile' consisting of two plates e is arranged around the fan, concentric with same, the two plates e being set at an angle to each other, so that'the streamsof gas and spray issuing from thepassagespf the fan strike two oblique surfaces-as indicated by the small arrows in Fig. 1. In the lower part of the casing, two additionalbaffleplates f are fixed at an angle to the wall of the casing, these plates being likewise curved to lie parallel with-the circumferenceof the fan. Gas and water deflected by the plates I e strike the in Fig.1.
In the modification shown in Fig. ,3 the fan ,wheel, designated a with vanes 6 has around it, in the casing a, a concave-convex bafile g, the convex-surface of which faces the circumference of the fan. Oblique baf plates f, as indicated by arrows With the baflies e and g, shown in Figs. 1 and 3 respectively,practically the whole of the gas and spray issuing under centrifugal action in a more or less radial direction, undergoes lateral deflection'by the baffles. This produces a very powerful cleansing efi'ect, by reason of increased inter-mixing of gas and spray, but it also considerably increases the resistance to the flow of the gas,
that is to say the load on the fan.
. Less resistance to the stream of gas and spray is ofiered by the arrangement shown m Fig. 4, wherein the fan a with vanes b is'surrounded'in the casing 0 by .bafiies 0 consisting of parallel plates, slightly bent aside, in an outward direction, sous to overlap each other, but without making contact (with each other. These plates thus form passages which deflect the stream of gas and spray without opposing much resistance to the'flow thereof. In the lower part of the icaslng the said passages direct the gas and spray on to oblique baflle plates F.
In the modification shown in Big. 5, baffle plates 6 surrounding the vanes b of the fan a in the casing 0 are bent inward, so as to form passages directed toward the central plane of the casing.
In the modification shown in Fig. 6 the I vanes b of the fan a," are surrounded, in the 80 fies f are fixed to the side walls of the casso that the plates '6 and e form two outwardly directed oblique passages for the gas and spray. The plates 6* and 6 have at their outer edges chan'nelsh for receiving the liquid flowing down the baflie-plates e and. a. suitable means (not shown) are provided to drain the liquid from the chan-' nels 71 In the modification shown in Fig. 7 the vanes b of the fan a are surrounded in the casing by fourbafile plates e The two plates at-the sides diverge outward, and the twoplates between them converge toward the central plane. The plates are not.showu with channels at their outer edges, but they may be constructed with such channels.
The bathe-plates may in all cases be made of smooth sheet metal, but I prefer to construct them of metal which is corrugated or more or less roughened at its surface, the eiiiciency being by this means increased.
I may use an additional bafiie or bafiics around the fan in the casing, outside the baiiies e, 9, etc., the inclination or convexity of the several battles thus arranged being selectedaccording to the velocity and pressure of the gas and spray at the parts where the bafiies are placed. .These battles are not only applicable to simple gas-washers of the type shown in Figs. 1 and 2', but they can also be applied to washers with appliances of the disintegrator type, such as shown in the specifications of United States Patents No. 1,049,317 and No. 1,042,840. 7
VVha-t I claim as my invention and desire to secure by Letters Patent of the United States is 1. In gas washing apparatus, the combination of a casing provided with an outlet and formed interiorly as a substantially an-' nular chamber gradually increasing in diameter in the .direction of said outlet; a centrifugal fan rotatably mounted in said casing and adapted to project a mixture of gas and liquid in a substantially radial direction, and a continuous bafiie concentric with and spaced from said fan, said bafiie having inclined surfaces to laterally deflect the gas and liquid mixture projected radially by said fan.
