SPECIFICATION forming part of Letters atent No. 716,7 57, dated December 23, 1902. Application filed February Y25, 1902. Serial No. 95,638. (No model.)
To @ZZ whom, it ntcty concern/1,:
Be it known that we, WARD J AMES REN- WICK, a citizen of the United States, and .IO-V SEPH HEATON, asubject of the King of Great Britain, both residents of Auburn, in the county of Androscoggin and State of Maine, have made a certain new and useful Invention in Gas-Purifiers and we declare thenfollowing to be arfull, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference Ybeing had to the accompanying drawings, and to letters of reference marked thereon, which form a part oi this specification.
The drawing is a-central vertical section through our invention.
The invention relates to apparatus for purifying gas; and it consists in the novel construction and combinations of devices, as hereinafter set forth.
The object ofthe invention is mainly to provide means for effectively removing impurities from acetylene gas without changing the gas-pressure.
In the accompanying drawing, the let-ter c', designates the gas-purifying tank, in which is placed the puriiyying solution, above which the gas is collected, passing off from the top,
of the chamber by the distributing-pipe b. c is the gas-inlet pipe from the generator, this pipe extending up centrally in the tank to a point above the level of the surface of the chemical solution. Connected to the bottom of the tank is a Ug-form pipe d, havingan upward extension d', forming a water seal.
Also connected to the bottom of the tank is inlet-pipe c, supported upon the same and having openings in its side or base portion ffor the passage of the gas-from said pipe.
This canopy-top is preferably of convex form and is provided with a supporting-rod or upper extension Z, terminating short of the cover of the tank, and'on which are carried a series of two or more supporting disks or plates m m, spreading at different heights above and over the canopy-top k and parallel thereto. The plates or supports m in are located at different heights and are of gradually-increasing diameters, the lower plate 'm being of greater diameter than the canopy l-'t and the plate above it of greater diameter than the plate below it. The plates m m are removable from the supporting-rod Z, which should be provided with supporting projections or collars, and these plates, as well as the top 7o, are designed to carry the removable mantles an u, which are of some textile or porous material usually having a strong affinity for the chemical solution in the tank below, into which the lower edges of the mantles dip. Inthis manner the mantles form a central and concentric gas-chambers having porous or capillary walls.
Above the series of mantles n n is located an annular convex bearing p, which carries a dripmantle r, which extends from its con tact with the solution up over the annular bearing and depends by its free end over `the upper mantle n, itbeing designed that Vthe solution carried 'up by the mantle r Vthrough its capillary action shall drip upon the upper mantle n. By the action of this drip-mantle it is designed toaid in securing a constant change or movement of the chemical solution in the mantles In. The mantles being constantly saturated with the solution purify the gas passing through them, taking up the impurities, which are in turn washed down and fall to the bottom of the tank.
In this apparatus the impure solution can be removed from the tank and the tank cleaned without breaking the water seal. So, also, the replenishment of the solution can be effected without breaking the water seal of the supply-pipe. The operation of the purifyingmantles does not alter the gas-pressure. The mantles are constantly saturated by the solution, and the gas in passing through these mantles from chamber to chamber leaves its impurities on said mantles, from which the IOO impurities are washed down by the solution to the bottom of the tank. When the drawo cock is opened to clean the tank and all the solution which can pass out has run off, there will still be a Water seal in the supplypipe and a Water seal on the drawoft pipe, and in this manner it is designed to avoid an external gasway. The purifying-tank can be emptied and relled without interfering with the passage of the gas through the tank.
Any suitable purifying solution may be used in the tank; but We prefer to use a solution composed of potassium or sodium hydroXid of varying strength to suit the carbid capacity of the machine.
Having described this invention, what We claim, and desire to secure by Letters Patent, 1s-
l. In gas-purifying apparatus, the closed tank, the inner mantle therein, and the outer mantle, having a depending upper end portion for discharge upon said inner mantle, substantially as specified.
2. In gas-purifying apparatus, the closed tank, the gas-inlet pipe extending through the bottom of said tank, and having a canopy or enlarged perforated he'ad at its upper end, and an upper extension, the plates having a removable connection with said extension, the upper said plate having a skeleton-form center,the removable mantles supported from said plates, the supply-pipe having` a trap or Water-seal connection with the tank, and the discharge-pipe having a similar connection with the tank, substantially as specified.
3. In gas-purifying apparatus, the tank, the gas-inlet pipe extending upwardly, and having a perforated gas-discharge portion or head, and an upper extension having supporting-collars, the removable supports resting upon said collars, and the removable mantles resting upon said supports, substantially as specified.
In testimony whereof We aix our signatures in presence of two Witnesses.
