SMOKE-WASHER.

Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed May 26, 1916. Serial No. 100,150.

To all whom it may concern:

Be it known that LFRANcIs W. WESTBROOK, a citizen of the United States, residing at Myton, in the county of WVasatch and State of Utah, have invented new and useful Improvements in Smoke-Washers, of which the following is a specification.

This invention relates to smoke washers, spark arresters or the like and has particular application to an apparatus for removing the solid matter from the smoke.

The chief characteristic of this invention resides in the provision of a device of this character comprising a receptacle or tank into which is introduced the smoke and a liquid, the smoke and liquid being thoroughly mixed prior to its introduction into the tank, the tank being provided with means for agitating the mixture whereby the solid matter contained in the smoke will be separated from the vaporous part and collected within the tank.

Another important object of this invention is to provide a device of this character in which the mixture within the tank is subjected to air pressure whereby the smoke will be thoroughly mixed with the liquid to cause an effective cleaning of the smoke.

Another important object of this invention is to provide a device of this character comprising a plurality of washing tanks arranged to successively wash the smoke, the tanks being provided with pipes and means within the pipes for controlling the flow of liquid and smoke to either of the tanks independently of the remaining tanks.

Another object of this invention is to provide a device of this character having novel means for thoroughly incorporating the smoke with the liquid prior to its introduction into the tank or tanks, and means for controlling the flow of the elements to the mixing means.

Another object of this invention is to provide each of the tanks with novel means for collecting the solid matter contained in the smoke and means interposed between the agitating means within the tank and the collecting means for preventing the former from disturbing the sediment contained in the last mentioned means.

Other objects of the invention will appear as the specification is read in connection with the accompanying drawings, in which Figurel is a slde elevation of the apparatus constructed in accordance with my invention.

Fig. 2 is a vertical sectional view of one of the tanks.

Fig. 3 is a horizontal section of one of the tanks.

Referring to the drawings in detail, A, B and C designate the mixing tanks respectively which are supported in vertical position upon a base 1 by means of the standards 2, the lower ends of the tanks being arranged in spaced relation to the base as is clearly shown in the drawings. 3 designates a horizontally arranged smoke pipe which has one end thereof communicating with the mixing tank A while its opposite extremity is in communication with a furnace, I having diagrammatically shown a blower 4 of any suitable construction for conveying the smoke from the furnace to the tank. Arranged in superposed relation to the smoke pipe 3 is a water pipe 5 which is in communication with a feed pipe 6 while its opposite end is connected to a suitable source of Water, an injector 7 being arranged within the pipe for feeding the water through the pipe as will be understood. The smoke pipe 3 and water pipe 5 communicate with each other by means of mixing pipes 8 and 9 which are inclined in opposite directions and are each provided with valves 10 and 11 respectively whereby the flow of smoke or liquid through the pipes may be controlled. In order to control the flow of the smoke and liquid through the pipes 3 and 5, I have provided each with hand operated valves 12 and 13 respectively. The valve 12 in the liquid pipe is disposed at a point between the mixing pipes 8 and 9, while the valve 13 is disposed forwardly of the inner mixing pipe 9. It will be seen from this construction that when it is desired to mix the smoke with the liquid the valves may be opened and closed to direct the smoke into the water pipe or vice versa as the operator may elect. Assuming that it is desired to feed the mixture of smoke and water into the tank A, by closing the valves 11 and 12 and opening the valves 10 and 13, the water within the pipe 5 will be directed through the mixing pipe 8 and into the smoke pipe 3, whereupon the water will be mixed with the smoke and the mixture introduced into the tank A. The mixing pipe .andthesmoke and water pipes may be com;

posed of suitable sections of pipe so as to permit the disconnecting of the sections whereby the different pipes may be'cleaned. Connected to the inner endof the waterpipe 5 is the feed pipe 6 which is provided with a semi-circular section 14 which is adapted to extend around the tank to a point diametrically opposite its connection with the water pipe whereupon, it is bent at an angle to lie in alinement with the water pipe. The feed pipe then extends around thenext tank B and across to and around the next tank G in, a manner, similar to its position with relation to the tank A. Connecting with the upper endof each of the tanks A, B and C are overflow pipes 15 which extend upwardly and then do. ;nwardlyv between each of the tanks, their lower ends connecting with the tanks at apoint adjacent their lower ends as. at16; The vertical portions of each of the overflow pipes 15 intersect and are .in

communication witlithe feed pipe 6, the lat ter being provided withv valves 17 and 1.8 respectively upon opposite sides of the overflow pipe 15, while the overflow pipe is provided with valves 19 and 20 above and below its point, of; intersection with the feed pipe;

Reverting to the operation. of the valves uponthe mixing pipes 8 and 9 to direct the flow of mixture, inorder to directvthe mixture into the feed pipe 6, the valves 10 and 13 are closed while the valvesll and 12 are opened whereby the smoke will pass upwardly through the mixing pipe 9 intothe water pipe 5 and thereby mix with the water. T hemixture will then pass into the feed pipe until, it reaches the valves 17 and 18,, the course of flow then depending upon the position of the valves within the feed and overflow pipes. Assuming that it is desired, to feed the mixture to tank B, the valves 18 and 19 are closed while the valves 17 and 20 are opened thereby permitting the mixture to flow through the feed pipe and downwardly through theoverflow pipe-into the tank B. If it is desired to continue the use of tank B, the valves 17 and 18 are opened while the valves 19 and 20 are closed whereby the mixture will be directed to the next, intersection. of the overflow and feed pipe as will, be understood. It. will thus be seen from this construction that I may direct the flow of mixturethroughthe feed and overflow pipes so as, to feed the mixture to-any orv all tanks.

To agitate the mixture within the tanks to thoroughly mix the smoke withthe water and to give a greater surface area for the water, I have provided each of the tanks withdashers 21, the blades of which are inclined downwardly as at 22. The dasher shank'23' extends upwardly through thetop of the: tank and through. a sleeve 24, the-upper-end: of the' shank- 23 f projecting beyond the sleeve and provided with a beveled gear 25 which is adapted to'mesh with a second beveled gear 26, the latter being keyed upon a horizontally arranged shaft 27 which is rotatably supported by means of supports 28 secured to each of the tanks. It will be .seen from this construction that upon rotation of the shaft 27, the dashers 21- will be synchronously rotated through the medium of the gears 25 and 26.

The lower end wall-of each of, the tanks is ofvinverted frusto-conical formation as indicated at 2-9, the apex of which is provided with a valve controlled outlet 30. Owing to the formation of the bottom wall 29 the solid' matter contained within the smoke will be caused to precipitate to the apex thereof whereby the same may be removed from the tank by the opening of'the valve.

Disposed within the tank and arranged at the intersection of the bottom wall with the body of the tank is a substanti-allyconical convexed deflecting plate 31 which is rigidly supported by means of legs32. The deflecting plate 31 is disposed atthe larger end of tho-bottom wall and directly below the lower end of the dasher 21 and is of; a diameter less than the internal diameter of the tank w iereby the sediment or solid matter. contained in the mixture upon, impinging upon the upper surface of the plate will be deflected to the peripheral edge thereof and then downwardly into the conical bottom. The deflecting plate 31 further serves to prevent the agitation of the mixture from disturbing the sediment contained, within the sediment chamber or bottom wall and thereby insuring a proper collection of the sediment at all times' In providing the dasher 21 with downwardly inclined plates, the solid matter contained in the smoke is directed downwardly within. the tank and thus further insures the thorough separation of the solid matter from the vapor.

In order to. cause the smoke to. remain in contact with the water during the mixing of: the two, I have provided each of the tanks with. air pipes 33 whereby air under pressure is admitted to the tanks, the pressure being indicated by gages 34. To prevent excess pressure within the tanks I have provided each of the pressure pipes with safety valves 35 at a point adjacent the connection of the overflow pipe with the tank, the safety valves being of any suitable construction to obtain the desired" results.

The operation of my smoke washer is briefly as follows; assuming that all of the tanks are in operation, the water and smoke are mixed within the mixing pipes 8 and 9 by manipulation of'the valves as has been described, the mixture then passing into tank A through the pipe 3 at a point be tween the lower end ofthe dasherv and the d fl ct g-- p a her y pon- .rot ianof the dasher the water and smoke will be thoroughly mixed and the solid matter contained within the smoke precipitated into the sediment chamber. After tank A has received its full capacity of mixture, the mixture then passes into and through the overflow pipe into the next tank B whereupon the same action takes place as in tank A and the overflow of mixture is then fed into the tank C. The mixture after passing out of tank C may be disposed of in any suitable manner. If it is desired to discontinue the use of tank A, the valves 10, 11, 12 and 13 may be manipulated to direct the water and smoke through the feed pipe 6 around the tank A and into the tank B, it being understood that the valves 18 and 19 are closed. Thus it will be seen that tanks B and C will then be in operation. If it is desired todiscontinue the use of tank B, a similar operation of the valves will take place as has been described in reference to tank A, it will thus be seen that I may use any one or all of the tanks, the operation of one tank being absolutely independent of the remaining tanks, and that the smoke may be subjected to any number of washing operations depending upon the solid matter contained within the smoke.

, It is thought that from the foregoing description taken in connection with the accompanying drawings the construction and operation of my device will be apparent to those skilled in the art without further description and that minor changes in size, shape, proportion and minor details of con struction may be made without departing from the spirit and scope of the' appended claims.
