CHARLES V. BLODGET, OF NEV `YORK, N. Y.

AGAS-SCRUBBER.

SPECIFICATION forming part of Letters Patent N o. 460,300, dated September 29, 1891. Application filed March 14, 1891. Serial No. 384,994. (No model.)

To all whom it may concern:

Be it known that I, CHARLES WILLIAMS BLODGET, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented an Improved Gas-Scrubber, of which the following is a specification.

Myinvention relates to gas-scrubbers of the type known as hot-tardry scrubbers. The

scrubber and finally discharges into a suit-A able receptacle while the gas is conducted into a holder,

The object of my invention is to produce a cheap, simple, and efficient apparatus, which will thoroughly eliminate all tar from the gas by a purely mechanical process and without the use of any purifying material.

. The subject-matter claimed is hereinafter specified.

The accompanying drawings represent so much of my improved apparatus as is necessary to illustrate this sub j ect-matter. Unless otherwise specified, the parts are of ordinary construction.

Figure l is a side elevation, partly in section, of the scrubber; and Fig. 2, asimilar plan View. Figs. 3 and 4 are respectively perspective detail views of the solid and perforated diaphragms employed.

The arrows show the direction of movement of the tar and gas. a risingmain A to the dry scrubber, which it enters at the top and at one end. This scrubber is shown as composed of a series of inclined troughs B B', ttc., live in number, resting one upon the other and connected alternately at opposite ends by passages C C', dac. The bottom of these troughs is left unobstructed, so that the tar thrown down may flow continuously therethrough in a direct course; but the gas is caused to pursue a much more devious course by means of a series of The gas passes through` transverse diaphragms or partitions D E. These diaphragins are shown as alternating in the troughs, Which are provided with closed apertures or hand-holes G at suitable intervals to afford access thereto for cleansing, &c. The diaphragms D are shown as constructed in the form of oblong plates secured to braces or cross-strips (Z in such manner as to leave a free space around all fouredges, around which the gas may fiow after impinging against the plates. The alternate partitions E are shown as perforated or divided centrally and supported by braces e, and with their upper and outer edges close to or against the top and sides of the troughs, leaving' openings at the bottom for the flow of the tar and one at the center, through which the gas passes and iinpinges against the adjoining solid partition. The outer corners of these plates are shown as clipped diagonally, so as to leave spaces e. The gas entering the scrubber passes around the edges of the plate D, through the central opening in adjoining plate E, and, impinging against the next solid plate D, is thrown laterally against the Walls of the trough, passing around the edges of the partition and through the central aperture in the next partition. The impingement of the gas against the surfaces and its friction thereon break up the globules of tar and the tar descends to the bottom of the trough, along which it flows. The purified gas and tar are finally taken off at F.

I claim as my invention 1. The combination, substantially as hereinbefore set forth, of a trough havingan inclined bottom, inlet and outlet openings for the trough, and alternately solid and perforated partitions suspended in the trough and above the bottom thereof, the solid partitions having spaces between their edges and the walls of the trough, for the purpose specified.

2. The combination, substantially as hereinbefore set forth, of a trough, gas inlet and outlet openings therein, alternately solid and perforated partitions suspended in the trough above the bottom thereof to leave a free coutiuuous passage for the fiow of tarry matter, and gas-passages above and at the sides ot' the solid partitions and at the center of the perforated partitions.

IOO

3. The combination,substantially as hereinpartitions being arranged above the bottom Io before set forth, of a series of inclined troughs, of the trough, for the purpose specified.

,gasinlet and outlet openings therein,passages In testimony whereof I have hereunto sub- Connecting each trough with the one iininedi scribed my naine. v 5 ately below it., alternately solid and perforated CHARLES NV BLOD GET transverse partitions suspended centrally t therein, leaving passage-Ways at the top and XVitnesses:

sides of the solid partitions and at the center FRANK S. OBER,

of the perforated partitions, and all of said EDWARD C. DAVIDSON.
