METHOD F AND APPARATUS FOR CONDENSING FUMES 0R GASES.

SPECIFICATION forming part of Letters Patent No. 601,677, dated April 5, 1898. Application tiled August 14:, 1897. Serial N0. 648,234. (No model.)

Apparatus for Condensing Fumes or Gases, of

which the following is a full, clear, and exact description, reference being had to the accom panying drawings, which form a part of this specification.

My invention has for its object certain improvements in the method of condensing fumes and gases and in apparatus for carrying out said method.

It` consists in conveying water to the top of a condenser, holding it in temporary suspension, and at the same time diffusing it overa large area, cooling the water while so suspended by a draft of air, and then causing the Water to trickle down into and through a passage containing the fumes or gases to be condensed leading from the smelting-furnace or other source, thus causing a partial condensation of the fumes. The fumes then pass into a condenser consisting, preferably, of a rotary conveyer formed of an Archimedean screw, the revolution of this screw drawing in the gas or fumes from the main chamber into a small division thereof.

described. An exhaust-fan is located at thev top for the purpose of drawing the air up through the brushwood.

The invention willbe better understood by y reference to the accompanying drawings, in

which- Figure 1 is a section on line 1 1 of Fig. 3. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3 of Fig. 1. Fig. 4t is a section on line A 4 of Fig. 1.

A` is a gas-inlet pipe leading to the condensing-chamber B. A short distance above the gas-inlet is arranged a horizontal framework composed of `the slats or girders C, ex-

tending between the walls of the condensingchamber and forming an open-work compartment designed to support a mass of looselypacked brush D, which nearly iills the upper part of the chamber.

F is a partition extending inwardly from one side of the condensing-chamber below the surface of the 'water in the bottom of the conrevolves with the spindle E2, which is revolved by any desired means. This type of rotary screw-cylinder is fully described and claimed in Letters Patent No. 557,880, issued to me April 7, 1896, and forms nopart of my present invention.

I prefer to arrange my apparatus so that the water may be 4taken from the lower part of the condensing-chamber to the top thereof and allowed to descend throughthe condenser to the bottom, thus completing the circuit and thus saving the by-products heldin suspension in the water, and also in case therev should be` any scarcity of water making it necessary to supply `only such quantities of fresh water as will compensate for the water lost by evaporation. To this endl project a pipe Gr' from the side of the condensing-chamber a short distance below the level of the water therein and connect the horizontally-disposed perforated water-distributing spray-pipes I-I (shown in plan in Fig. 2) near the roof of va condensing-chamber withy a pipe H', extending through the roof and down along the side of the condensing-chamber in proximity to the pipe Gr', and interpo'se between pipes H and G apump G on an elevated platform alongside of the condensing-chamber. By

this arrangement Water is pumped from the Ido ' and through the brushwood D.

Immediately beneath the openwork bottom C of the.brush-compartment are arranged the horizontally-disposed air-distributing pipes I,

.(shown in plan in Fig. 4,) connected to an air-supply pipe I'. These pipes I are provided with perforations in their upper surfaces, and the dripping water is, prevented from entering therein by means of the air-pipe shields J, secured to the bottom of the slats or gird-j ers C.

Immediately above the gas-inlet pipe A and ubelow the air-distributing pipes I is a perforated horizontal partition K,eXte`nding from wall to wall of the condensing-chamber, and kbelow this partition K are the staggered horizontalwalls K. The perforations are small, so that the water constantly dripping through them will form practically a seal to prevent the escape of the gas or fumes, except directly through the staggered passage, andthe object of this staggered arrangement of walls isto afford a long passage for the gas or fumes, so as to give ample time for carrying on the process of condensation, which is effected by the Water previously cooled by the draft of air through the brush coming in contact with the fumes or gas as it drips through the perforations of the staggered walls.

At the extremetop of the condensing-chamber above the spray-pipes H is an air-chamber L in communication with an exhaust-fan M, arranged exteriorly of the condensingchamber. By revolving the exhaust-fan a constant circulation of air is induced from the air-distributing pipes I through the brush D.

N is the gas-outlet pipe eXtendin g from the side of the condensing-chamber immediatel below the -partition F.

At the bottom of the condensing-chamber is a water-outlet pipe O, through which the water is drawn off when it is desired to supply entirely fresh water to the apparatus or when access to the bottom of the tank is desired to remove the solid matter deposited thereon.

The operation of the apparatus is probably sufficiently clear from the foregoing description, but it may be summarized as follows: The pump is first set into operation to withdraw the water from the bottom of the condensing-chamber and raise it through pipes G and I-I to perforated pipes H. The water is distributed through these pipes and is sprayed through the perforations thereof onto vthe brush D, through which it percolates.

The exhaust-fan at the same time is caused to revolve by any suitable means, inducing a current of air through the'brush, reducing l .the temperature of the water percolating through the same. The water thus cooled walls K. The fumes or gases are then admitted through the pipe A and pass back and forth between the perforated staggered Walls. The action of the Water upon the gas or fumes Aprecipitates much of the solid matter previously held in suspension. The remaining stepvof the process is effected in the spiral conveyer E, the solid matter remaining in suspension being precipitated therein and the refuse passing out through pipe N.

I do not intend to limit myself to any specific construction of condensing-chamber nor to the means I have described for suspending and diffusing the water vWhile the current of air is passed over it' to cool it; nor do I intend to limit myself to any particular feature of construction hereinbefore described, except by those claims wherein such particular feature is expressly set out as part of the combination claimed.
