Our invention relates to gas washing and refers to the apparatus used in connection While our invention is particularly adapted for use in connection with washing gas distribution of from blast furnaces, it may cleaning gas of any description which contains mechanical impurities such as soot, fluedust or the like.
The gas washing apparatushereinafterdescribed is an improvement upon applicants" co-pending application, Serial No. 42,361, filed Oct. 25,1915. i
i In order to suiiiciently wash gas in vertical towers it is necessary to secure an equal both the gas and the water over the entire cross sectionalarea of the apparatus containing the washing elements;
in other words, channeling of both' the gas and water must be avoided. We have found that this is best accomplished by compelling a repeated distribution of both the gas and water at different levels of the tower. The washing is carried on in successive stages in which the rough the lower stages and the fine cleaning in the final stage at the top of the tower. Each one of the rough or lower stages difi'ers radically from thepreceding'one, and compels a complete rearrangement of both gas and water.
The invention will be stood by reference to drawings, wherein,
Figure l is a vertical sectional View more readily underthe accompanyln'g through a gas washing tower constructed in accordance with our invention; Fig. 2 is a section on the line 2-2 of Fig. 1, and, Fig.
3 is a fragmentary sectional view of a modified form of the apparatus shown in Fig. 1.
In the drawingsit will be seen that we provide a vertical casing 10, having a gas inlet 11, and an outlet 12. The lower end 13, of the casing is in the :form of a cone,
1 thereby providing a-gas seal and overflow 14, serving to permit the escape of the water collected. The water for washing is Baas BACON, both citizens of residing at Chicago,

. one-sided or it continued-to do so throughout-the tower,

or eight rows in the group,
the baflies being set'on edge and parallel to each other, which breaks theas up into man small streams. These ba es are preferab y in the form of narrow wooden strips, all of which are placed vertically,-alternate rows being located at right angles to each other. The placing of such baflies in verti-. cal towers is old, 'butheretofore the entire tower, ora greater portion of it, was filled with them, andif the gas started its fiow otherwise unevenly distributed,
sweeping the water to the other side and resulting in a low efficiency of cleaning.- In
our construction if there is any one-sided 'flow of gas through the first group of baffies, it is broken up and redistributed by the concentric gas passages at 20, 21, formed by superimposed circular perforated trays 20, 21, arranged in concentric tiers as shown, which collect the water, from above and cause a shower of water to fall through the .gas, These trays in combination, cover the entire cross section of the tower and=there1 fore collect and redistribute every drop of water falling from the upper stages so that every section of the tower below these trays is bound to receive an equal amount of water. The gas being forced through these properly proportioned tray passages is also equally distr uted in reference to each section ofthe tower. Leaving the tray sections the gas strikes another hurdle section 22, in which the bafiies may be placed a little closer together than in the first section. This section again divides. the gas into many small streams and receives the water falling from the elements above. Leaving the last hurdle section, the gas then strikes the inclined bafiles which form the fine cleaning stage bythe impinging action of the e fresh wa ter'is applied to these inclined baffles by suitable spray nozzles laced at the bottom and top of these sets oi bafiles; or if desirable, Zschocke type or other forms of sprays may be applied to the top in order to furnish additional water. These bafiles are preferably arranged in three; series 23, 24, 25, two rows or bafies being placed in velocity of the gas,
each series and each row being inclined at right angles, to the baflles of the adjacent roar. These baflies are preferably-composed of narrow wooden strips and located in an all the bafiies of a single 90 removed from the bafiles of the adjacent The battles in the adjacent series,
angle. however, extend in a direction at right angles to the baflies in the next series, the individual arrangement of the baffles in that series, however, being the same as in the other. v
If a shortage of water exists, as is the case at many plants removed fromlakes and rivers, then the discharge water at the bottom may be lifted up to the top of the tray section and used once over again, thus cut ting down the amount of fresh water at the spray nozzles in the final washing stage. In this way great economy of water may be reached without detracting from the efliciency of the washing tower. We have designed towers of this description with two gas inlets so that the gas from two sources may be cleaned in the one tower. It is only necessary to dimension the tower and the gas passages in such a manner that the proper as has been found by us to give the best results is obtained. We have ascertained that the velocity through the lower parallel baflie sections'should be between five and fifteen feet per second; through the tray sections between fifteen and twenty-five feet; and through the final washing stage between the inclined baflies it should be between five and fifteen feet per second. I
In the modified construction shown in Fig. 3, the gas enters the tower 26, in the usual manner and immediately is caused to pass through trays 27, 28, whereupon it is section 29, as in the construction just described. In some instances this arrangement may befound to be Wehave found likewise that the washing apparatus depends'largely upon the velocity of the gas through the different stages or portions of the tower andthe velocities herein mentioned while possibly not absolutely-imperative have been sults in the apparatus employed.
Obviously the construction is capable of considerable modification and such modifidesirable. eificiency of the gas plurality of portion of said tower,
