APPARATUS FOR CONDENSING SMOKE, FUMES, AND GASES.

SPECIFICATION forming part of Letters Patent No. 700,934, dated May 27, 1902.

Application filed February 4:. 1901. Serial No. 46,021. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM B. J AOKSON, a citizen of the United States of America, residing at Denver, in the county of Arapahoe 5 and State of Colorado, have invented certain new and useful Improvements in Apparatus for Condensing Smoke, Fumes, and Gases; and I do declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specifica- I 5 tion.

My invention relates to an apparatus for condensing smoke, gases, and fumes from steam plants, furnaces, ore-roasting furnaces, and smelters, whereby the carbon and solids are separated from the smoke, fumes, and gases and discharged into the sewer or caught in receptacles when it is desired to save the carbon or recover the values. By the operation of my improved apparatus most of the 2 5 gases are united with the water employed in the condensing operation; but provision is made for the escape of any excess of gases that do not unite with the water.

The invention will now be described in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof. v

In the drawings, Figure 1 is a vertical longitudinal section of the condensing tank,

5 shown connected with the smoke-stack of a boiler-furnace, the latter being shown in end elevation. Fig. 2 is a section taken on the line so an, Fig. 1, viewed from below.

The same reference characters indicate the '40 same parts in all the views.

in size, as shown at 9, where it is conical in go shape and is connected at its smaller extremity with a pipe 9, which passes through an opening formed in the condensing-tank 10.

The pipe 9 protrudes into the tank 10, its discharge extremity being reduced or contracted. A steam-pipe 12, leading from the boiler, enters the discharge extremity of the conduit 9, its mouth being directed toward the pipe 9. This pipe. discharges a jet of steam and creates a partial vacuum, causing the smoke, 6o fumes, and gases to be discharged through the pipe 9 and into the tank with great velocity. I estimate that with a boiler-pressure ofone hundred pounds the smoke will be driven into the tank at the rate of seven thousand five hundred feet per minute. On the inside of the tank directly opposite the discharge extremity of the pipe 9 is mounted a funnel-shaped receiver 13, whose inclined walls terminate at a shallow receptacle 13, into which the smoke, fumes, and gases are directed. This receiver is vertically adj ustable in the tank, and any suitable means may be employed to effect this result. As shown in the drawings, a screw 14 is journaled in lugs 10-and engages a threaded'opening formed in the closed bottom of the funnel-shaped receiver. The outer walls of the funnel are provided with braces 13, whose free extremities slidingly engage the'inner surface of the tank and give the receiver the necessary support. In the top of the tank is located a coil 15of perforated pipe, communicating with the water-supply pipe 16, provided with a valve 17 for regulating the water-discharge. The water is sprayedfrom the coil15 downwardly into the tank, as indicated by the dotted lines.

The smoke is driven into the tank with such velocity and forcethat it instantly unites with the water and steam, and the resulting products fall to the bottom of the tank and are carried off through the open water-trap 18 into the sewer or to any suitable receptacle in case it is desired to recover the carbon. 5 The action of the water and steam on the smoke is both mechanical and chemical. The gases from smelters and ore-roasting furnaces will unite with water and may be discharged into the sewer, or if they contain mineral values the water may be drawn oif into suitable regeptacles and the values precipitated at wi l.

The top of the tank is provided with an escape-pipe 20 for any excess of gases which do not unite with the water. The passage through this escape-pipe is controlled by a weighted valve, whereby the tank is closed at the top except when the interior pressure is such as to open it for the gas-escape, as aforesaid.

By reason of the velocity of the discharge through the nozzle 9 the smoke, fumes, and

gases are carried across the tank into the receiver 13, which temporarily suspends the said products and gives the water and steam an opportunity to act upon them more effectively, whereby condensation is facilitated.

It must be understood that the condensingtank may be made of any suitable material. As shown in the drawings, it is supposed to be metal; but it is evident that any other desirable material may be employed.

Having thus described my invention, what I claim is 1. In an apparatus for condensing smokes, fumes and gases, the combination'of a condensing-tank, means for introducing water in the form of a spray into the tank, a conduit leading from the stack and communicating with thecondensing-tank for discharging the products of combustion thereinto, means for introducing a jet of steam into the tank at the discharge extremityof the said conduit, to give the desired velocity, and means mounted on the wall of the tank directly opposite the discharge extremity of said conduit, for temporarily suspending said products in the tank to facilitate condensation, substantially as described.

2. In an apparatus of the class described, the combination of a tank, means located in its upper portion and connected with a supply source, for discharging water thereinto in the form of spray, a conduit leading from the stack and communicating with the tank, its discharge extremity being reduced in size, a steam-pipe entering the smoke-conduit, and arranged to introduce steam into the tank through the discharge extremity of the smokeconduit, and a receiver mounted in the tank opposite the discharge extremity of the smokeconduit, to facilitate condensation.

3. The combination of a condensing-tank, means for spraying water downwardly from the upper portion of the tank, a smoke-flue entering the tank below the water-spraying means, means for discharging a steam-jet into the tank through the discharge extremity of the smoke-flue, and an adjustable receiver mounted in the tank opposite the smoke-flue entrance, to facilitate condensation.

4. In a condensing apparatus, the combination of a tank provided with a suitable outlet at its bottom, a perforated pipe located in its upper extremity for spraying water downwardly thereinto, means for discharging the products of combustion into the tank under pressure, and a funnel-shaped receiver located opposite the discharge for said products to facilitate condensation.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM B. JACKSON.
