SPECIFICATION forming part of Letters Patent No. 372,178, dated October 25, 1887.
Application filed May 21, 1856. Serial No. 202,844. (No model.)-
-To all whom it may concern:
nying drawings, in which Figurel is a vertical section of the apparatus. Fig. 2 is a view, on an enlarged scale, of one scrubbing-ball. Fig. 3 is an end view of the revolving drum. Fig. 4is a view of a detached portion of the drum. Fig. 5 is a ver-v tical section of the lower part of the apparatus, taken in a transverse direction from that shown in Fig. 1, and without thedrum.
I This apparatus is of the form known as a tower scrubber. It is composed of a series of chambers one above the other, which form a tower. The chambersA are preferably rectangular boxes of cast-iron having planed joints. They are divided from each other by ahorizontal plate, a,.having a vertical curb or passageway, b, cast therein. The area of this passageway is greater than the area of the gas inlet pipe. One side of each chamber Ais fitted with a cover-plate, 0, through which the revolving drum D, to behereinafter described, can be put in and taken out. Each chamber A is to be filled nearly half-full with water or other liquid. The top of the curb or passageway-b is higher than the level of the water. This passage-way is for the flow of the gas as it passes up from chamber to chamber. Each two chambers are connected on the outside by a pipe, d, which conveys the overflow-water from an upper to a lower chamber. The position of this pipe finds the water-level.
A revolving hollow drum,- D, is placed in each of the chambers A, and is mounted on a shaft, 6. These drums are formed, preferably, of two circular-ring cast-iron heads, f, which are filled in with Wire-netting or. perforated plates 9. The drums are divided up lengthwise by radial perforated plates 71. into any number of compartments, 1', according to the capacity and size of the apparatus.
On the periphery of the drums D a number of water boxes or buckets, k, are attached. Each box is thus segment-shaped and covers one of the compartments i. The outer plate of these boxes or buckets is tight, while the bottom next to the interior of the drums is perforated, as shown ate.
The compartments z of the drums are filled, preferably, with hard wooden balls Z,- but balls of any other material may be used. Each ball is pierced with two holes.
Each drum has a facing strip or edge, or, on one side, which is turned true and bears against the semicircular facingstrip 0, cast on the side plate of the box forming each chamber A. The facing-strips n 0 are kept in contact by means of the tail pin or screw 19 acting on the opposite end of the drum-shaft e. One side of the chambers Ais fitted with stutfing-box and gland q, through which the shaft 0 works. Each chamber Ais provided with one or more handholes and covers (not shown) for cleaning purposes. v
The apparatus stands on a suitable boxbase, R, which serves to catch the tar which may come over from the condensers. The tar passes down with the water through the pipes d. The gas-inlet sis in the base-box, and the outlet t is at. the top. The water orother liquid is supplied in the usual manner through the trapped pipe u at the top. The overflow or discharge for the liquid and tar is at o.
The apparatus operates as follows: Water or other liquid is first introduced into the apparatus through the supply-pipe it until the chambers A are filled up to the level of the overflow-pipe cl. Rotary motion is now given to the drums D. They may be rotated by any suitable or well-known gearing-saysprocketwheels and chains, bevel-gear,or worn1-gear-- fixed on the end of the shafts e. The particular means employed for rotating these drums is not important. It is simply necessary that the drums be rotated at about five revolutions per minute. The water-buckets k on the periphery of the drums in passing through the water or liquid contained in the lower half of the chamber A are filled and carry up and allow the liquid to fall through the perforations on the inside of the boxes, thus thoroughly wetting the balls Z in the drums. The water also falls from one compartment to v washing chamber A. Here the gas must pass through the whole length of the drum D- that is, from head to headand cannot pass this chamber A in any other way. The gas in passing through these drums is brought most intimately in contact with the continuallymoving and freshly-wetted sn rfaces of the balls, which thereby actually scrub the gas. After passing through the wholelength of the drum of the first chamber the gas finds its way over the top of the drum and up the passage-way 1) into the next chamber A. This process is repeated in each chamber until the gas passes out from the scrubber at the outlet-nozzle t. The surplus liquid impregnated with the ammonia and tar is drawn off through the pipe 12, which is situated in the base. The amount of water required is from three quarts to one gallon for every thousand feet of gas, according to the desired strength of the impregnated ammonia-liquor.
By this apparatus no backpressure can possibly occur. The apparatus will not foul, but instead is self-cleansing, and it will give the same results, no matter how long used.
Having described my invention, Iclaim and desire to secure by Letters Patent of the United States- 1. In. agas-scrubber, a drum having its ends and periphery of reticulated material, and provided with perforated radial partitions h and with water-buckets secured to its periphery, all substantially as shown and described.
2. In a gas-scrubber, the combination, with the water-chamber A, of a drum, D, on shaft 0, said drum having its ends and periphery provided with reticulated material,and the buckets it, connected together on the periphery of the drum, said drum also provided with perforated partitionsh,forming co1npartmentsi,l1aving perforated balls Z therein, whereby the liquid or water enters the compartments through the ends and periphery of the drum and is discharged from one compartment to another through the perforated partitions h to thoroughly clean the gas, as shown and described.
In testimony whereof I affix my signature in the presence of two witnesses.
VM. SIMPKIN.
