INVENTOR. LOUIS MQRlE ROUSSEAU BY Z AGENT MOBEE REFUSE INCINERA'IOR The invention relates to improvements in mobile devices and equipments for the incineration of household and industrial refuse.
It becomes more and more difficult to find grounds where to dump household and industrial refuse and residual mud from town and factory waste water and the like. The more or less appropriate places suitable for this purpose are rarer and rarer, and the number of miles separating the points of collection necessitate the use of vehicles which must cover distances which increase the price of an operation already sufficiently expensive. This problem of useless runs is the same when fixed existing incineration works are foreseen. But the problem must be studied with great attention when several grouped localities needing such an installation are concerned.
Besides, certain sea-side or winter resorts only need an incinerator during some months. If the acquisition of an incinerator is already a heavy expense for a municipality which within a score has the same number of inhabitants every month all the year round, the same effort cannot be demanded from those resorts as the cost of the destruction of their refuse would be multiplied by 3 or 4.
It is therefore urgently necessary to solve these problems. A solution which from the economical point of view allows a reasonable investment and a reduced running cost; a solution which from technical and practical points of view leads to a satisfactory result, that is, the mobility of the incinerator as a simple trailer and a low proportion of unbumt material.
In present installations the cylindrical shape of the furnace requires that it must be inclined at a certain angle to secure the displacement of the refuse products. This inclination has the inconvenience of necessitating the use of a buttress of considerable size to resist the thrust of the weight of the furnace at this angle.
On the other hand the cylindrical construction gives a uniform mass and volume. The weight entails necessarily a high cost of the structure. While the volume of the combustion chamber in the incinerator is normal in the refuse input end, it becomes too important as the products move and become incinerated. This too large a space above the refuse has for result to expand the gas which allows only a feable turbulence (hence a nuisance for combustion) when an important quantity of calories is needed for the rise in temperature (900 to l,l C) in the furnace, and the maintaining of this temperature during its use.
The refuse whose calorific value lessens as the buming takes place is incapable of supplying the calories. The continuous use of a burner is then necessary and this does not enhance the reduction of the cost of the operation.
The present invention concerns improvements to mobile rotary-drum furnaces, usually called incinerators, dealing with thermal treatment of household and industrial refuse and mud from town and factory waste water and the like. The object of this invention is to render mobile an incineration equipment in order that with the same installation refuse may be incinerated on 6 According to important features of the present invention, these improvements are characterized by:
l. The construction of an original furnace allowing its mounting on a trailer or semi-trailer whose dimensions correspond with international trafiic regulations.
2. The conical shape of the furnace as just described,
ensuring a regular travel of the refuse products incinerated, towards an ash-bin, which allows:
a. the processing of different refuse products;
b. the use of a furnace whose voltune decreases as the products are burnt;
c. the presence of an additional controllable air inlet becoming lesser as the products are reduced;
d. the concentration of strong air turbulence over the refuse;
e. the needing of less calories for the rise in temperature on starting, and the keeping of this temperature during operation;
f. the keeping of the lower part horizontal or nearly so which position needs no important buttress for supporting the furnace, and also allowing the passage of mud;
g. the considerable reduction of the diameter of the run-way;
h. the needing of less concrete and other materials for the construction;
i. the use of a reduced-diameter air distributor;
j. the having of a rotary gasket to insure tightness on the ash-bin side, and to have the latter of smaller size;
k. the reduction of the number of vents; and
l. the rendering of refractory concrete stronger due to the conical shape of the fumace.
3. The possibility of the use of removable, in-
terchangeable and adjustable vents which permit: a. The penetration of the necessary oxygen for combustion in the heart of the mass of refuse to be burnt. These protruding vents are equally of use for the moving and mixing of the refuse as it is tumbled inside the rotating conical furnace portion.
b. Their being fed by fresh air by means of conduits placed on the outside of the furnace and thus allowing to lower the external temperature of the same.
4. The use of the chassis of the trailer as a support for the furnace and the accessories.
Other objects, features and many of the attendant advantages of the invention will be readily appreciated as the same becomes better understood by reference to the following detailed description, when considered with the accompanying drawings, wherein FIG. 1 is a longitudinal side view of a preferred, exemplary embodiment of the inventive mobile refuse incinerator;
FIG. 2 is a top plan view of the device shown in FIG.
FIG. 3 is a longitudinal side view of the device as seen from the side opposite to that of FIG. 1;
FIG. 4 is an end elevational view of the device as viewed from the right-hand end in FIG. 1 of the drawings;
FIG. 5 is a somewhat schematic vertical lengthwise section of the rotary furnace portion in the device;
FIG. 6 is a transversal cross-sectional view of thefurnace portion along line 6 6 of FIG.
FIG. 7 is a vertical lengthwise sectional view, with parts broken away, on an enlarged scale as compared to the right-hand end of FIGF 5;
FIG. 8 is an enlargedtvertical sectional view of a portion of FIG. 7, for better illustration of one of the vents; and
.FIG. 9 is a similarly enlarged vertical sectional view of a cyclone and chimney forming part of the device, along line 9 9 of FIG. 2.
In the somewhat schematic drawings, and particularly in FIGS. 1 to 6 thereof, numeral 1 identifies a chassis or frame of a semi-trailer used for mounting the illustrated preferred embodiment of the inventive mobile refuse incinerator; 2 generally designates a furnace; 3 is a hopper for loading the refuse to be incinerated; 4 is an ash-bin; 5 is a gas duct or conduit; and 6 is a burnt-gas decantation cyclone (shown in detail in FIG. 9).
Two run- ways 7, 7 are fixed on an inner jacket 8 of a conical rotary drum 19, in the position shown in FIG. 1. An outer jacket 45 will be described somewhat later. These two run-ways rest on four rollers 9 fixed on frame 1 at point 15. The rollers are driven by a mechanical device 16 which is conventional. Rollers 9 give cone or drum 19 a rotary movement about its own center by the intermediary-of run-ways 7, 7'.
Chamber 11 has in its upper part a gas evacuating conduit or opening 12 for exhausting the produced gas. In its lower part a tray 13 is provided to remove or pass rubbish beyond a joint 14 shown between the fixed part of the furnace 2, namely chamber 1 1, and its mobile or rotary part,.thatis cone or drum 19. The passage of refuse in chamber 1 1 considerably reduces the percentage of moisture.
Simultaneously with this the drying refuse is ignited by a burner 17 at the rear end of the furnace (see righthand ends of FIGS. 1 to 3, 5 and 7). From drum l9 burnt gases reach chamber 1 1 in a direction opposite to that of the refuse, due to the pressure reduction caused by a smoke extractor 25. This post-combustion zone being submitted to very high temperatures, the gas is cleaned of its still combustible elements. They are evacuated by conduit 12 in gas duct 5.
The refuse matter to be burnt, introduced by tray 13 (FIG. 5) into conical rotary drum 19, moves in the direction of arrow X as an effect of a mechanism 18, shown in broken lines, and leaves the furnace at its rear end, and falls in the form of ashes in a water vessel or basin 41, by way of ash-bin 4.
Combustion air which has been previously warmed up and fed by a blower enters an air distributor 20 (FIGS. 1 to 4) by an air passage or conduit 21 which partly surrounds gas duct 5 in a heat-exchange relationship. The air is supplied to the interior of distributing ducts 22 (FIGS. 5 to 8), enclosed between inner jacket 8 and ventilating ducts 45 constituting the earlier-mentioned outer jacket 45, by means of adjustable vanes 23. Through these ducts air for combustion, caught by cowls 26, reaches lower vents 24. It penetrates the center of the refuse to be incinerated by the way of openings 27 at the inner ends of vents 24, as shown in FIGS. 6 and 8. Vane: 23 have openings which permit only the vents 24 to receive air for combustion which reach into the refuse to be burnt.
As vents 24 protrude into the inner space of drum 19, they contribute to the intermixing of the refuse which is tumbled or rolled around in the furnace as it is rotated (best seen in FIG. 6). The combustion air is introduced through terminal openings 27 right into the refuse mass as it is being tumbled.
It should be noted that the same burner 17 is used in order to incinerate refuse of low calorific value which has already been employed for starting the furnace fire,.
Gas (see arrow Y) blown back by extractor 25 into cyclone 6 (FIG. 9) must pass baffles 30, 31, 32 before reaching a chimney 33. This chimney includes in its lower part a curtain 34 of hanging chains, the curtain assisting in a final cleaning of the gas. This curtain is mounted on a shaft 35 so that it can freely swing, which permits to shake the same by means of a lever 36 in order to get rid of any dust and deposit which has accumulated. A discharge gate 37 (see FIGS. 2 and 9) ensures the evacuation of ashes falling into cones 38, 39.
The ashes leaving drum 19 fall in ash-bin 4 and then in water basin 41 (FIGS. 5, 7). The ashes are then cooled, and the water level 42 obtained by an air lock 43 ensures that the air-tightness of the furnace is maintained since air might impair the proper adjustment of the combustion. The removal or evacuation of ashes may be continuous or intermittent, depending on the size of the device.
Air-tightness of the revolving parts of furnace 2 (namely drum 19 and ducts 45) with respect to the stationary parts, namely chamber portion 11 and ash-bin 4, is ensured by gaskets as shown in FIGS. 5 and 7. A gasket 44 is fixed to a jacket 49 of chamber 11, passing between two rotary soft flanges 47, 47 while these latter are fixed to ventilation ducts or outer jacket 45. A circular element 57 joins jackets 45 and 8 (see FIG. 7) to close ducts 22. A rotary gasket 46 fixed to ducts 45 and a gasket 46, also fixed to ducts 45, as well as jacket 8 pass between stationary soft flanges 48, 48', fixed to air distributor 20, the latter being in turn fixed to ash-bin 4 by means of a member 58. Flanges 47, 47,
48, 48' are fitted at their edges with copper bands 56 rubbing lightly on gaskets 44, 46, 46'. This continuous contact ensures air-tightness Post-combustion chamber 1 1 is isolated from hopper 3 by a circular jacket 51 (FIG. 5) in which water circulates. The water avoids that a high temperature be transmitted to hopper 3.
In FIG. 8 numeral 60 indicates a rod welded or otherwise secured at one end to vent 24 and having the other end threaded. Two nuts 61 secure each vent 24 and cowl 26 to jacket 8. A lug 59 welded to jacket 8 holds vents 24 and cowls 26. Arrow Z shows the flow of combustion air.
In FIGS. 1 to 3, numeral 52 identifies a fuel tank, at 53 there are water tanks and 54 is a generating set supplying electric current, necessary for the operation of the mobile refuse incinerator so as to render it completely self-contained. Hydraulic struts 55 ensure the stability of the equipment and assist in providing the necessary inclination.
Those skilled in the art will understand that the preferred embodiment of the inventive mobile refuse incinerator permits, for the first time, the incineration of rubbish or refuse for example by grouped town syndicates or by large towns where dumping grounds exist, and the reduction of mileage in unloading the collecting vehicles. Due to this mobility the smallest boroughs can now get rid of their refuse by incineration according to hygienic rules, by making use of the inventive device.
It should be understood, of course, that the foregoing disclosure relates only to a preferred, exemplary embodiment of the invention, and that it is intended to cover all changes and modifications of the example described which do not constitute departures from the spirit and scope of the invention.
