' This invention relates to dehydrating incinerators and has for its principal object the disposal of wet sewage screenings-. 01 sludge in a clean and efiicient manner. p
The sludge may be Obtained froni the sewer by any suitable process. Usually it is dripping wet and in such a dense and mucky condition that it will not readily burn, and hence it must be drained or dried before it is possible to incinerate it. By't'he use of an incinerator such as disclosed in this invention, the sludge may be dumped therein just as it is extracted from the sewer, whereupon it will be dehydrated and burned. The incinerator herein 1 described is also well adapted to receivefdried'screenings or such material in any condition in which it may be obtained. Garbage and other refuse will also be readilyconshmed as well as practi: cally any other combustible material.
The above objects of this invention are ac: complished by a" novel disposition of mate, rial treating portions of the incinerator, which may include grates in combination with oil burners to dry the sludge and ignite it. At least one of the grates may be used for coal firing to augment the oil burners or to substitute for them at times when they may be out of operation. Other of the" grates may be of water tube structure combined with a water jacketed furnace wall providing a durable heat resisting structure which is adapted for use as a steam generating chant: her so that the incinerator becomes a source .Of both heat and power which may be used for any desired purpose. Forced draft and preheating means may be employed, and any perature in a gas combustion .chamber.
through which the gaseous products of combustion pass, thus reducing'smoke to; a minimum, and substantially eliminating odor.
The particular nature of the invention as well as'other objects andadvanta'ges thereof will appear more clearly from ,a detailed description of a preferred embodiment as illus trated in the accompanying. drawings in which j V Fig. 1 is a sectional longitudinal elevation thru the center of the: incinerator 1 1g. 2 is a sectional end view takenalong U the line 2'2 of Fig. 1, and
' Fig.3 is a plan vie w taken along theseetieii' 3-3 of Fig. 1. H 7
Referring to the drawings, a chutel provided with atrap-door 2 is built into the flooring or'platform 3 such. that trucks may' be driven up and dumped near'the chute,or into the chute directly." Any other suitable means of conveying material tothe chutemay be employed. The chute 11 leads into thelinciner ator 4, passingthrough an opening in the boiler or steam generating chamber 5 which forms the sides and t'op'of a combustion chamber 4a.. Directly under the chute fl is a drying grate: 6 forming a platformflocat'ed ata distancebelow such that a suitable depth ofmaterial may be deposited thereon. This grate is composed'of parallel water tubes in dividually terminating at each end inafre} ducing point 7', "therear endsoftIie-tube'S being connected thereby [to a" supporting header 8 which spans the combustion chamber Leland connectswith the water-jacketed wallsfiaof the incinerator at the pointsQin' are connected'by' the reducing joints 7 to tubes 10,whichfpass through sleeves in the front water-jacketed wall of the incinerator and connect with the header 11 by means "of the PS 12. This header extends alesgthe front of the incinerator and aroundeachend to; connect with the wat'ter-j acketed sidewalls 5a of the incineratorat' the 'oints 13 inFi The tubes are so connecte astobe readily cleaned gf j 'Below' the grate 6 is a second grate comprising the bars 14 supported at the ends by cross-members which are supported at the Sol lower part of the furnacewall, Thisgrate is adaptedltoburn coal as well as any refuse which may drop through the drying grate above. Coal is supplied through the opening in the front water-jacketed incinerator v v r closed by the doors 16. The his grate comprises an ash pit 17 hich access may be had through the doors 18. At the bottom of the pit is a drain 20 to carry-off liquids to the sewer. At each side of the drying grate 6 is provided an oil burner 25, one above and one below, (Pg-2), the purpose of which is to dry out the wet sludge that is deposited on the grate 6 and to accelerate the combustion throughout the chamber. -Water dripping from this'sludge which is not evaporated will be drained out from the bottom of the ash pit through the drain 20. The purpose of the coal fire is to augment the operation of the 011 burners, but it may be operated alone under conditions wherein the oil burners are not needed or .may be dispensed'with entirely when the hydrocarbon burners are adequate for the treatment ofthe sludge or refuse.
As the sludge dries on the upper grate 6 it is stoked through a door opening 27 that is normally closed by doors 28, and is pushed off onto an intermediate grate 26, where, if
all the moisture has'not been removed from it, the sludge becomes thoroughly dried and will begin to burn. The material is pushed off the uppergrate 6 by any suitable tool, the opera tionbeing facilitated by the parallel and longitudinal disposition of the grate members.
The intermediate grate 26 comprises the water tubes 26a the rear tubebeing somewhat raised above the plane of the grate to prevent material droppingover the rear. 'The tubes extend across the combustion chamber and are connected at one end directly to the waterjaeket of. the Wall 5a of the incinerator, and
the other ends of thetubes pass through sleeves in the Wall of the furnace atthe' opposite sideof the incinerator and are fitted with T-sections 29, an outletof each .T-section being connected withitubing 30 that with suitable fittings leads back to thewater-j acketed side wall 5a as shown in Fig. v 2. This construction allows the tubes 26 to be cleared as the T-sections are closed by removable plugs aligned with the bores of the tubes 26.
.This grate maybe observed and raked through the openings '31 inthe incinerator '35 and 14 are adapted to be shaken. "lhefarrangement is such that partly burned or unburned material may be transferred from either of these grates onto the other. The
gap between them is bridged'for this purpose by an inclined surface 36 placed above a cross wall 37 which separates the ash pit 17 from the pit 38 under the rear grate 35. This grate is accessible through the doors 39 in the side of the incinerator, and the ash pit 38 is reached through doors +10. The front and rear walls ll of the ashpits Hand 38 are shown as being Il)0i1111$ that support the front and rear wateujacketed walls of the combustion chamber of the furnace structure. The side Water-jacketed walls are likewise supported by these I-beams. The whole metallic structure of the incinerator is placed on a concrete base 42.
The gaseous products pass out of the furnace chamber 4a through the opening i3 in the rear water-jacketed wall 5a and into a gas combustion chamber lined with refractory material 51, and provided with a bafiie wall 52, the chamber being accessible through the doors 53. An auxiliary oil burner 13% is placed near the entrance of this chamber and is adapted to build up the'temperature to insure the reduction of all odors and the complete combustion of any smoke or'other floating material which might be stirred up by the draft in the combustion chamber. In this manner the amount of soot is reduced to a minimum and very little smoke is emitted from the stack, sothat the plant operates in the cleanest possible manner and with no odor that would otherwise oifend neighboring habitations. 1
An air preheatcr is placed in the chamber 50, which is comprised of lateral rectangular dncts 56 through which the flue gases pass, and vertical rectangular ducts 57 carrying a forced draft that is supplied to the preheater through a conduit 61 leading from a fan 62 drivenby a motor 63, downwardly to a conduit 58; I This conduit leads to the bottom of both grates let and 35. The amount of draft supplied to either grate may be regulated by the dampers 59 placed in the conduit at its entrance to the spaces beneath the grates. v v
The flue gas-is conducted from the preheater 55 through theo'utlet passage 64 which 'rnay be partially or completely closed by a damper 65. This damper iscontrolled by means of a cable or chain 66 passing over a pulley 67. i
It will be understoodthat various changes may be madein the arrangementof the'preferred embodiment herein described without departing from the principles of the inventionas defined in the appended claims.
