Application filed September 28, 1925. Serial No. 59,216.

This invention relates to a process and apparatus for treating gases issuing from smelters or other metallurgical apparatus or produced in other metallurgical operations,

blast furnaces and the like, or other gases containing noxious or objectionable particles of solid, liquid or, gaseousma tter. Its object is to produce a new and improved apparatus andprocess for separatingparticles of solid, liquid or gaseous matterfrom fumes, smokes or gases in a more efficient and practical way than has heretofore been the case.

The nature of the apparatus and process will be best understood and'followed from a consideration of the following description considered with the accompanying drawings. In the drawings which accompany this description paratus embodying my invention. Fig. 2 is a longitudinal sectional elevation ofFig. 1.

Fig. 3 is a transverse section taken on the line 33.of Fig. 1 and looking in the direction of the arrows.

Fig. 4 represents a transverse section on the line 44 of Fig. 1 looking in the direction of the arrows.

of Fig. 1 looking in the direction of the arrows. p v 5 Referring to the drawings numeral 1 indicates the main bod portion or chamber of the washer-orcon enser. A cone shaped body 2 leads from this main body port1on or chamber to the stack or chimney 3 affording an outlet for the washed or purified gases. The gases to be washed or purified enter by means of the inlet 4 and are assisted in their travel through the apparatus by an injection of wet steam from the pipe 5 entering a constricted portion of the gas inlet ipe 4, thereby insuring a continuous trave of the gases through the apparatus. The inlet 4 is flattened, as shown in Figs. 1 and 4, at its point of entry in the part 1 of the apparatus into two parts 6 and 6' conforming withthe angular 'or con- 5 conical shaped bottom 7 is constructed the Fig. 1 represents a plan view of the ap Fi 5 is a transverse section on line 5-5 ical shaped bottom 7 of the apparatus. The V angular or conical shaped bottom continuesthroughout the length of the ap aratus fromor triangular, I do not-desire to be restricted to this particular shape as I may make the bottom of arcuate shape either convex or concave or any equivalent shape. Theparts 6-6 of the inlet means necessarily must be made to conform with the shape that the bottom 7 assumes.

As is shown in Figs. 1, 3 and 4the apparatus is provided with water spray nozzles 10 entering both sides of the apparatus through the. verticahwalls 8 thereof. .These spray atomizin'g nozzles 10 are supplied with water from the water linell and with air from the air line 12, the purpose of the air being to forcibly inject and minutely divide the water as it leaves the nozzles 10. Suitable valves 13 and 14 respectively "control the water line 11 and the air line 12 while valves 15 and 16 respectively control the admission of water and air to each of the individual nozzles 10 as indicated in Figs. 1, 3 and 4. As

shown in Figs. 1, 3 and 4 the main water and air lines. 11 and 12 are connected through suitable pipe connections 17 and 18 with the individual nozzles 10 and their connections.

At the top of the angular bottom 7 there is provided a spray 19 composed of a pipe perforated at frequent intervals desi ed to spray jets of water in a vertical an lateral to the outlet 20 in the stack- 3.

' The water, condensed steam and collected particles flow out from the portions or compartments 1 and 2through the discharges 21 arranged at the base of the angular or conical portion 7 and passing through the side walls 8. The quantity of water and contained particles leaving the apparatus through the discharges 21 is usually sulficient to efiectively seal these discharges from the outflow of gas or fumes through them,

but when the conditions are such that the quantity of water used and the matter contained by it after use does not accomplish construction or may be constructed of any hung from the top of the body portion 2 or I a constricting or compressing action due to other materials capable of resisting any cor-. rosive or destructive action of the gases treated.

Within the interior of the conical body portion 2 baffles may be provided for 001-,

lecting and arresting entrained particles. These baflles may conslst of wires or screens otherwise sup orted therein, and should be constructed 0 such material that the corrosive action of the gases will be resisted. The V baflies may be provided in only a part of the chamber or throughout its whole length.

In operation gases or fumes enter the inlet 4 and are assisted in their passage through the ap aratus by the injection of wet steam from t e pipe 5. The steam not only assists the motion of the gases throughthe apparatus but moistens and permeates the solid or semi-solid matter contained therein. The

steam contained in and surrounding the particles becomes condensed through the cooling action of the water sprays, whereby a rapid precipitation occurs not only due to the steam condensing-within the particles but u on them also. The stream of gas is. thenattened out into two inclined portions in the parts 6-6 and then passes along the top of the angular or conical shaped bottom 7 of the portions or compartments 1 and 2. While the gases are thus spread out in a roof shaped fashion they are subjected to the action of the wet'steam from the pipe 5, water and air from the nozzles 10 and the water from the waterjpray 19. After the gases leave portion or compartment 1 they enter the conical portion or compartment 2 of the apparatus where they are subjected to the gradually decreasing cross-sectional area of the conical part 2 while being subjected to the action of water spray 19. After the treatment in the portion 2, the gases leave by'means of the outlet 20 and escape through the stack 3,
