Application filed my a, 19:1. Berill 30. 530,301;

My invention relates to retorts, and more especially to directly heated vertical retorts particularly adapted to the treatment of filter material, such as, slag, coke, or other 5 coarse substance, which has been fouled or c coated during the ifilteringprocess with a combustible volatile matter or'slu'dge having a very high moisture content, and in the prelimina treatment of same to vaporize conl 'siderab e moisture'before said combustible matter or adheringsludge is dissipated or burned.

The object of the invention is to provide and construct a retort of the character above indicated, which is capable of being cheaply manufactured and continuously operated at a minimum of cost without skilled labor, and will also enable all necessary repairs to. be quickly detected and effected. A further object of the invention is to provide a retort occupying a minimum of s ace and having structural characteristics an arrangement of cooperating elements whereby the fuel consumption is reduced to a mimmum for the material treated due to the repeated use of the products of combustion, preheating of the air for combustion, and no great loss of heat units carriedmfi by the treated material dischar ed from the retort.

I Further objects and a vantages of the invention will be manifest from the detailed construction of the retort and its mode of operation to be hereinafter described.

The invention consists of structural characteristics and relative arrangement of elements to be hereinafter more lly described and particularly pointed out in the appended claim.

In the one sheet of drawin in which similar reference characters in icate the same parts in the two figures;

Figure 1 is a vertical sectional view of the retort cutting the combustion chamber and connecting flues; and, e

Figure 2 is a transverse section'taken on line II -II of Figure 1. w a

Referring to the drawing, 10 is theretort havin an inner chamber 11, preferably. rectangu ar in cross-sectionandtapered or enlarged fromits upper charge opening12to- -ently described.

its bottom or discharge opening 13. The up per or charging'end 18 provided with a feed. hopper 14 aud ts lower'opening with an extractingconveyor 15, which are common and well known expedients in this class of de- 66 vices and need no further or detailed disclosure. I a

Opposite side walls of said 'retort'are prov vided preferably with three distinct and separated sections 16, 17 and 18, having perfora-- tions, or openings, or passageways 19, which communicate with the interior of the tapered inner chamber 11 at upper, intermediate and lower zones of the retort 10.

Surrounding said retort 10 is a suitable hol- 7 low structure 20, preferably constructed ofv the usual fire brick, or similar material, in which is formed a furnace 21, orother means for the production of hot gases, the combustion chamber 22 of which is so constructed 7 and arranged. as to have its outlet in communication by means of the perforations 19 with the interior or chamber 11. of the intermediate zone or section 17 of the retort-' .10, as clearly shown in Figure 1 of the drawing. 1 4 Adjacent to and on the opposite side of the retort 10 from that of thecombustion chamber 22 is formed a flue or vertical passage 23, which extends between a short distance from the top and bottom of the retort 10, as illustrated, and is in communication by means of the three sets or separated series of perforations 19 with the interior of the tapered chamber 11 at the upper, intermediate and lower zones of said retort 10, as will be readily understood. Said zones, or perforated retort sections 16, 17 and 18 being referably separated by upper and lower horizontalbrick work or baflies 24: and 25 made integral with the walls of the retortand subdivide said vertical flue 23 into pockets /or

chambers

26, 27 and 28 connected by passageways 29 and 30, as. indicated, for purposes to be pres- 31 is an up er flue which is connected by means of pe orations 19' to the interior of perforated upper section 16 or zone of the retort and also 'to the exterior of'the ap'paratus, or suction-of a fan, not shown, as is readily understood and needs no further illustration.

32 is a lower flue which is preferably connected to the outside air-and by means of perforations 19 with the interior of the adjacent lower perforated section 18, or' lower zone of" the retort, asshown. 1 Y i The parts of the retort being constructed and arranged as herein described and the fuel in the furnace 21 having been ignited 'so that a proper supply and draft. of hot gases are developed in the combustion chamber 22, said hot gases will be drawn, as indicated by the arrows, through the perforations 19' and gravitating material within the intermediate perforated section 17, or calciner of the retort 10, and'in so doing will volatilize or incinerate any carbon residue, combustible matter or sludge absorbed or adhering'to said material before said hot gases pass into the opposite and adjacent chamber or pocket superimpose chamber 27, as indicated by the arrows, and meets and intermingles with and assists in the final combustion of the hot gases produced, drawn off and passed through the calcming or incinerating section 17, herein ex lained.

The said a ove mixture of burned hot gases and preheated air enters, as indicated by the arrows, through the passageway 29 into the superimposed chamber 26 and thence by means of perforations 19 passes the upper perforated walls 16 and newly charged fouled non-combustible material within the upper zone or drier section of the retort 10 below the charge opening 12 to eliminate, take up, oryaporize considerable moisture content from the fouled material and proper- 1y repare and'dry the same in order when said dried material gravitates or progresses to the intermediate zone or calciner section 17 the hot gases may efliciently and quickly incinerate, burn volatilize, destroy and remove the combustible matter on said fouled material or filter substances, such as, slag, coke, or analogous coarse material, as previously explained. 1 ,c

The intermixed hot gases, after passing through the upper. perforated walls 16 and the non-combustible material in the upperzone section of the retort 10, as just described,

enter the'chamber 31 from which the mois-,

ture laden cooler gases are drawn, as indi-' cated by arrows, through a flue by an exhauster or fan, not shown, to any desired point of the plant, or auxiliary heat conserving apparatus, if so desired and need no further disclosure.

From the foregoing disclosure of the con struction of the apparatus and the manner of operating the same, it will be seen that all the objects and advantages recited in the statement of invention have been fully and od comprising a series of physical steps in i a well defined order, as claimed, to effect, in a highly eflieient, thorough and inexpensive manner, the removing of adhered or absorbent combustible substances from a gravitating column of non-combustible material with a minimum loss of heat units, cost of operation and instrumentalities for carrying out said method.-

WhatI claimis: 4

A vertical retort apparatus, including in combination, a vertical retort, a material feeder at the top thereof, a treated material discharge outlet having a discharge valve at a the lower portion thereof, said retort havin side walls including upper, intermediate, an

lower perforated sections having solid wall extensions therebetween, a vertical flue adja-' centone retort wall and extending. from the lower perforated wall section to' the upper perforated wall section, spaced upper, mtermediate, and lower flues adjacent the perforated sections in the opposite retort wall, said upper spaced flue bemg opposite the upper portion of said vertical flue, and said lower spaced flue being opposite the lower portion of said vertical fine and open to the atmosphere, and a furnace for producing heatin gases and adjacent said intermediate space ue and directly connected thereto.

In testimony whereof, I hereunto aflix my signature.
