Specification of Letters Patent.

Application file d December 13, 1912. Serial No. 736,597.

To all whom it may concern:

Be it known that I, ALFRED ERNST, a citizen of the United States, resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have made a certain new and useful Invention in GasGleaners; and I declare the following to be a full, clear, and exact description of the same, such as will enable other skilled in the art to which it appertains to make and use the invention, reference being had to the. accompanying drawings, .and to letters or figures of reference marked thereon,'which form a: part of this specification.

Figure 1 is a ,central vert'cal section of The invention relates to apparatus for cleaning gas, and particularly gas liberated in gas producers from bituminous coal and it consists in the novel constructionand .combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention in an apparatus of preferable form, the numeral 2, indicates a casing, the upper portion 3, of which is preferably of cylindrical form, and is provided with a central recess 4, the bottom of which is in the form of an annular water'seal cup 5, around a central opening 6. To the top of this portion is attached the outlet pipe 7.

The chamber in this portion disposed around the recess 4 is annular, and is provided with perforated racks 8, for the reception of drying material designed to ab-- sorb inoist-ure from the gas after being washed. To .this upper portion is connected the main lower portion of the casing, extending downward and provided at its bottom with a water-holding connection 9,

which is preferably a water-seal tank or basin having am overflow pipe at 10. In the casing are provided an upper chamber 11, for a centrifugal water distributing device, and a lower entrance chamber 12, which extends below the water level and to which the entrance pipe or inlet-13,, is connected. The wall of a tubular throat or partition passage 14, extends centrally upward into the upper chamber 11, and downward from theupper chamber through the lower chamber, separates these chambers and is'terminated at or slightly below theoverflow level by a horizontal series of .s notches or passages 15, through which the crude gas is designed to pass from theentrance chamber, into this throat or passage and upward into the main cleansing chamher. A drain passage 16, which may be circumferential, extends downward from the sloping floor of the upper chamber into the water holding basin. This throat or Patented May 20, 1913.

partition passage is therefore designed to provide communication between the en..

trance chamber and the washing chamber only through the water of the tank.

Through the central opening 6, of the top of the casing extends a shaft 17, the upper portion of which is water-sealed in the cup 5,;above which it is provided with a pul ley or other .means of communicating "motion. The lower end portion of the shaft extends into ,the interior vertical tubular passage 14, and is provided with blades 18. The middle portion of the shaft is provided with fan blades 19, and,'below these, with a rotary inverted cup device, the skirt or wall of which extends downward around the upper part of the tubular passage l-it. This skirt or wall is provided with exterior ledges 20, which may be and usually are of bracket-form and horizontal or inclined;

and opposite this wall the casing wall is 1 provided with flanges 21, which are inclined. The casing flanges are arranged at levels between the cup ledges, and, as the casing wall and cup wall are designed to be parallel, or nearly so, the annular deflecting passage between them is arranged to distribute the gas and water particles inan even manner.

A water supply is provided in the upper part of the casing, asindicated by the jets at 22. shown in the chamber 12, near the water level and preferably directed toward the passages or serrations 15, these being designed to wash away the tar'and soot which tends to float and accumulate in thewater of the entrance chamber-around these passages.

Inthe operation of the apparatus, the

crude gas from the producer, entering the lower chamber 12, is drawn over the surface of the water inward through the horizontal series of notchesor passages of'the tubular wall in separate streams, which are subdivided by the bubbling action into small portions, which, being brought into contact with the mass of water of the tank, are ma-' terially cooled. Also much of the heavier soluble matter is taken from the gas. The gas, moving upward through the tubular passage 14, is deflected downward by the skirt wall of the inverted cup, and, at the same time, is given a whirling mot-ion, which continues as it passes around the edge of this wall upward through the defleeting passage between the ledges of the cup wall and the flanges of the casing wall. Meeting the falling spray, which is given centrifugal motion as it passes outward and inward between the flanges of the casing wall and the ledges of the cup wall, it is further washed and cooled, the soluble matters falling upon the sloping bottom of the upper chamber and being drained into the tank below through the circumferential drain passage of the casing. Below the drying chamber the wall and flanges of the casing slope downward, and the cup wall has also a downward slope, and the ledges of the exterior of this wall are preferably arranged in staggered relation, or separated at intervals by vertical passages, it being designed to obviate the collection of heavy extractive in this part of the apparatus, and to facilitate'its downward movement. The cleaned and moistened gas is carried to the outlet through the drying material on the racks of the drying chamber which is made sufliciently extensive to provlde for a comparatively slow movement of the gas, and in this way to promote an effective drying action, so that the gas passing through the outlet pipe will be in condition for use.

In some cases, in order to provide an abundant distribution of the water or cleaning fluid, supply spouts 23 may be arranged around the casing at different levels, to discharge the fluid toward or upon the shelves of the rotary inverted cup or deflector 25. In these cases, the casing ledges maybe dispensed with, as the discharge from the spouts will cause lateral inward currents of the gas.

I claim 1. Apparatus for cleaning gas, comprising a casing having an entrance chamber and a washing chamber, a water holder at the bottom of said entrance chamber, an overflow -for said water holder, an inverted deflecting cup within the washing chamber, and a tubular partition passage within the entrance chamber extending upward into said deflecting cup and downward into the water holder, said passage being provided with rotary blades above and passages at the water level for causing the gas to bubble through the water from the entrance cham-- her into the partition passage.

2.
