-- g sate-raisins Toallzjtukcm it mag cerium: Y Be it known that 'I, ALFRED zen of the United States, and a. resident of have invented wcertain new' and vuseful Improvements in Processes of Cleaning Gases, of which the following is a: specification; f
. The inventiont relates to a rocess for cleaning and purifying the-gases yextractmg by-products and impurities from the gas, 1
The object of the invcntionis" to produce a simplle and effective gas cleaning process.
T e invention may- -be used" w th m'any kinds of as, and I have selected for illustra ticn of t e rocessa machine designed for washin an 'purifying'the gases liberated in f by re uct coke ovens," andfo r extracting the y'products, such as ammonia andta'r. 1

down through the pipe I into the water seal B. 'lhe lower surface of theupper end of the-cupC is also provided with beatprovided -with a series of concentric annular shelves J which preferablyare progress ively longer'from the lowest to the highest and which are provided at frequent intervals with depending blades or vanes K. The outer casing H incloses the space around the cup- (3 and extends from the tube A downwards,- and outwards and then upwards, flaring slightly-instead .of being p ar-' al'lelwvith the wall of the cup C. At the'- Ltdp H offthe easing it is provided with a water-seal M for-the-shaft O and the gas er portion of the a paratus, and prefera y in the gas outlet "ls-.flhc'ated a second spray nozzle O Wl.'1l0l1 'deliversaspray into the gas above the remy cu l l'n'slspray falls partly on the top oft e cuptO, partly on the shelf J, and

against the inner wall of the casing. Thence flowing downwards and inwards along the stationary shelf L, it drips onto the next shelf J, from which it is again thrown ofi in a fine spray against the casing. Again it flows downwards and inwards over the sec- ,shelves J and L and is intimately subjected to the water on the surface of the stationary shelves and in passing each of the shelves J is subjected to the fine spray thrown there from directly across t e space through which the gas/is passing. It will be seen that the gas as it passes outwards from the lower end of the cup C, passes upwards in this devious course to the gas outlet N, while the cleansing liquid from the spray 0 passes downwardsin the opposite direction to the gas and finally escapes from the lowermost shelf L through the water-sealed ipe I, carrying with it the absorbed or colected impurities. The gas therefore meets the Water in a fresher condition at each succeeding shelf as it passes toward the gas outlet, while the water passing downwards becomes richer and richer in impurities from the gas. I make no claim broadly, however, to the passing of gas and liquid in opposite directions-for this purpose.
The other details of the ap aratus will be readily understood, as app ied, to those skilled in the art, without further description. It will be seen that the gas is first subjected to a spray by which it takes up ya or, and if highly heated is considerably "coofed by the spray. As a second step the gas is subjected to beating and centrifugal action as it passes downwards to the lower edge of the on C, and then passing upward between the she ves J and L it is subjected intimately to the wet surfaces. It is subjected to the centrifugal action and to the sprayin action on the outer side of the cup 0 and to t e flowing water on the shelf L, the water flowing downward and the gas upward. Lastly, it is subjected to the spray 0. As the gas thus cleaned passes from the apparatus with an excess of moisture, I prefer to pass it through a second apparatus substantially like that described, with the exception of the water sprays. In this second apparatus any condensed vapor or free moisture will be thrr wn out by the action of the apparatus, carrying with it the absorbed ammonia, and whatever other impurities it contains will drain down into the water seal beneath the apparatus. In place of the water spray at G I may in catching beaters an a troduce steam or part steam and water, according to the condition and qualities of the gas to bewashed, the choice, as will he understood, depending largely on the composition and tem erature of the gases. I desire also to 1nclu e as equivalents other liquids used in place of the Water.
1 claim the following:
1, The improvement in the art of cleaning gases, which consists in subjecting the inipure gas to a spray or jet of water or steam and causing the gas to take up vapor, then subjecting the gas to a combined beating and centrifugal action, allowing the excess of liquid with contained impurities to drain off,
and then passing the gas in an'upward direetion between water-bearing shelves and there subjecting it to a beating, spraying and whirling action and to successively purer quantities of water.
2. The improvement in the art of cleaning gases, which consists in subjecting the gas while in a heated state to finely divided water and causing evaporation and draining oil and the excess of water with attendant impurities, subsequently passing the gas in an upward direction and subjecting it while passing upward to a whirling, beating, and centrifugal action and to intimate contact with water passing'in a downward direction and itself subjected to being thrown by the centrifugal action in a line spray across the gas currents.
3. The improvement 111 the art of cleaning gases, which consists in subjecting the gas while in a heated state to a spray of water or steam and causing the as to take up vapor before being subjected to centrifugal and beatin effect, then conveying the gas to d subjecting it to combined heating and centrifugal action, subsequently passing the gas in an upward direction and there subjecting it while passing upwards to a beating action a plurality of times and to successively purer uantities of water each time, for substantial y the purposes set forth. 4; The improvement in the art of cleaning gases, which consists in subjecting the gas while in a heated state to a spray of water or steam and causing the as to take up vapor before being subjected to centrifugal and beatin efiect, then conveying the gasto beaters and subjecting to combined beating and centrifugal action, subsequently passing the gas in an upward direction and there subjecting it While passing upwards to a beating action a plurality of times and to successively purer quantities of water each time and subse uently subjecting the as to a jet or spray o 1 Water after it leaves the immediate vicinity of the beaters,for substantially the purposes set forth.- 5.
