APPARATUS FOR CHEMICAL REACTION O NlHEA TED SOLID MATERIAL.

Application filed January 27, 1927. Serial at. 163,930.

This invention relates to apparatus-for chemical reactions Wherethere is a mass of solid material and a gasiform substance, at elevated temperature; and .it is amongthe.

objects of the invention to provide for: efii-- cient va orizingand supplying such sub-;

stance, a so for removing refuse from the site of-reacti0n. Other ob e'cts and advantages will appear as the description .procoeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the features hereinafter fully described,

- and particularlyv pointed out in the claims,

the following description and the annexed drawings illustrating but one of the various ways in which the principle of the inven tion may be employed.

In said annexed drawingsz 'Fig; 1 is a vertical sectional view of an embodiment of the invention; Fig. 2 is .a vertical section taken on a plane at right angles to that of Fig. 1; Fig. 8 is a sectional detail on larger scale; and Fig. fl is a view at right angles to Fig. 3, with the door removed and the setting partly broken away.

The reference character 1 in the drawing designates. a reaction chamber for retort 1, preferably separable or removable and .of tubular form, round or elliptical or of other desired crosssection. Beneath each retort,

a clean-out chamber combined with a vaporizer is arranged. This may take the form of a receptacle 2 having a horizontal partition 3 therein, the compartment above the partition serving as an ash or refuse receiver, while the compartment below the partition serves as a-vaporizing chamber.

The supply conduit or pipe 4 opens into or connects with the lower compartment, and may have a trap 5, the main supply of the material. to'be vaporized being furnished tacle 2 has a door or closure 7 and the partition 3 is spaced back'there 0m substantially to allow free communication from the lower compartment to theupp'er and to the retort. A pedestal 8 maybe provided, preferably integrally, for the support of the receptac e 2. I Surmounting the .retorts are heads 9,

' which may be of sufiicient capacity to pro- "vide magazine feed, and each head has a closure 10 and an outlet connection 11 ,leading to a condenser or absorber system, (not 1 shown).

In-the same generalsetting, a gas pro,- ducer or generator 12 is included, masonry Walls T in --common being preferably employed, and-from the producer a duct 13 communicates directly with mixingports 14 in conjunction with 'an air supply flue 15. Theair supply'flue is arranged in a regeneratoror ,rec u'perator construction with the outgoing flue ltj' for the stack gases, and in this manner the air feed for the combustion system is brought up to temperature facilitating eflicient From the ports 14, afiue system surrounds the retorts and the receptacles 2, vertical and horizontal bafiles being arranged to di-' vert the hot combustion products for circulation about the respective units.

te r'ial to be employed. In'the case of carcombustion.

bon disulphide manufacture, this will be carbon, in the form ofcharcoal for instance.

The temperature is brought up by combustion in the flue system to a red heat for instance in thecase of CS manufacture, and

the material vto be va orized is supplied .from the pipe 6 into t e vaporizing compartment at the base of receptacle 2.. In the .case of sulphur, it is preferable to melt the sulphur in a suitable'melter, not shown, and

forward the molten sulphur through the pipe, regulating thefeed as required by the valve. The products of reaction in gase ous form are taken ofi through ,the outlet 11 to the .condenser or absorber system.

The retorts '1 may be' made of ceramic material, or of metal, as cast iron,to suit the. process being worked. Similarly the receptacles 2 may be made of ceramic material or of metal, and a one-pieceor integral construction is particularly desirable; For carbon disulphide manufacture, a ceramic retort andcast iron-vaporizer is preferred.

With the'assembled units in compact arrangement together with the heating means,

as in accordance with'this invention, heat introduced into the-system is utilized to its largest extent. and a uniformity ofcontrol is to be had in a manner not obtainable in isolated and separate unit construction.

Moreover, the arrangement of the vaporiz eris such as to utilize heat effectively and at' the same time not interfere With the functioning of the clean-out portion:

Gas mixing ports may be provided to add combustible to the tlues at any point desired, as for instance beyond the retort and before the vaporizer if additional heat in excess of that available. from the spent' gas be required there. In this Way the larger portion of the heat maybe supplied to the Vaporizers iidesired.

Other modes of applying the principle of the invention may be employed, change being made as regards the details disclosed, pro.- vided the means stated in any otthe foilowing claims, or the equivalent of such, b68111- ployed. y

it therefore particularly point out and distinctly claim as my invention:

1. In apparatus of the character described, the combination of a reactionchainber, and separate chambers for an a'sh pot and a vaporizer thereunder.

2. In apparatus of the character described,

the combination of a reaction chamber,

' separate chambers for an ash pot and vaporizer-thereunder, and heating flues about the reaction chamber, the ash pot andthe vaporizer. b v 3. In apparatus of the characterdescribed,

the combination of a reaction chamber, and a "one-piece 'partition-separated ash pot and vaporizer. V

4. In a paratus of the-character,described, the combination of'a reaction chamber, an ash-chatnber thereunder, anda vaporizingchamber', under the ash-chamber..

I 5. ,In' apparatus of the character described, the combination of a. ".jreaction chamber,- a
