Description

UNITED STATES PATENT QFFICE.
. WILLIAM H. ST. JOHN, OF NEW YORK, N. Y.
' IMPROVEMENT m GAS-PURIFIERS..
Specification forming part of Letters Patent No. 154,352, dated August 23, 1874; application filed February 24, 1874.
To all whom it may concern:
Be it known that I, WILLIAM H. ST. JOHN, of the city, county, and State. of New York, have invented an Improvement in Apparatus for the Purification of Gas, of which the following is a specification-z This invention is an improvement upon my invention for the purification of illuminatinggas, for which Letters Patent of the United States were issued to me September 2, 1873. Its object is to insure the more thorough or intimate contact of the gas with the purifying-liquid; and to this end it consists in the combination of fixed breakers or dividing devices with one or more of the dip-tubes described in the aforesaid Letters Patent, such devices being arranged to break or divide the current or currents of gas issuing to and through the liquid.
The drawing is a front view and vertical section of an apparatus constructed according to my invention.
A is an ordinary hench of retorts; B, the hydraulic main thereof, and a the stand-pipes, which, being continued within the hydraulic main, constitute the dip-pipes thereof. At such level as to secure the usual sealing of the aforesaid dip-pipes is an outlet-pipe, F, which connects with the lower compartments of a tank, 0. This tank has a horizontal partition, b, from which depend the dip-tubes at, opening at their upper ends into the upper compartment of the tank, and at the lower ends into the lower compartment. The liquor (derived primarily from the distillation of the gas-producing material in the retorts, and precipitated to liquid form in the hydraulic main) flows through the pipe F to the lower compartment of a tank, 0, and is maintained therein at a height suflicient to seal the diptubes at, the greater or less depth of the seal thus provided to the tubes being regulated by ian adjustable outlet-valve at d. From the upper portion or gas-space of the hydraulic main to the upper compartment of the tank extends a gas-conducting pipe, D, which, midway between the hydraulic main and the tank, is furnished with an exhaust, E, drawing the gas from the hydraulic main, and forcing it under pressure to the tank, which latter has ts outlet A* leading to the gasometer or other suitable receiver. Provided horizontally underneath the lower ends of the dip-tubes is a perforated plate, w.
The gas, forced under pressure into the upper compartment of the tank 0, passes down through the dip-tubes a into and through the liquor contained in the lower compartment of the tank, and finally, escaping from the liquor, passes to the outlet A*. On its way from the dip-tubes, however, and during its passage through the liquor, it is caused to pass through the holes or orifices in the perforated plate, and the current from each dip'tube is thereby broken up and dispersed, and. the gas consequently more intimately commingled or brought in contact with the liquor than would be possible without such breaking up, division,
or comminu-tion of the currents of gas issuing from the dip-tubes to and through the liquor. The chemical action of the substances held in solution by the liquor upon the impurities originally contained in the gas is, therefore, materially increased, and the purification of the gas thereby rendered more rapid, effectual, and complete.
When preferred, the perforated plates may be of wood or any other suitable material. Moreover, in lieu of the perforated plates, sheets of wire-cloth, of any preferred mesh say, one inch or one inch and a quarter-may be employed; or fixed bars, gratings, or the like may be affixed in or below the lower end of each separate dip-tube, to subdivide or break up the current of gas issuing therefrom to the liquor in the lower compartment of the tank. Furthermore, the principle of this my invention is equally applicable to an apparatus in which but one dip-tube or hydraulic seal is used as to thosein which a more considerable number is' -adopted, as herein set forth. 7
What I claim as my invention is- The combination of fixed breakers or dividing devices, with the end or ends arranged for sealing of one or more dip-tubes, a, substantially as and for the purpose herein set forth.
WVM. H. S1. JOHN.
