Definitions
- the subject of the present invention is a waste incinerator apparatus, as well as an incineration installation equipped with such an apparatus.
- the invention relates in particular, but not exclusively, to an incinerator intended for use on ships.
- International regulations prohibit the discharge into the sea of most of the waste produced by ships, in particular household waste, plastic packaging and bottles, oil residues, oily rags used to clean the machines, etc. It should be noted that the nature of this waste is very heterogeneous, and certain materials burn and are eliminated by incineration much more easily than others.
- the objective of the present invention is to propose an apparatus and an incineration plant which, while being simple in design and of a low cost price, are easy to use and allow to burn with a high efficiency and without danger of fire of materials, even motley.
- document FR-A-1 231 6 describes a heating device which also performs an incinerator function.
- the appliance comprises a hearth provided with an opening for loading the waste to be incinerated, an air intake opening, a combustion grate disposed at the bottom of the hearth, and a chimney vertical discharge. This is connected to the upper wall of the fireplace and opens into the atmosphere, upwards.
- the device is equipped with electrically controlled fans, whose role is to improve the draft, and therefore to carry out an efficient and complete incineration.
- this device is attractive, since the suction effect of the water injection nozzle is supposed to improve the draft and the evacuation of smoke. Unfortunately, such an installation cannot function in practice because the volume of water which necessarily occupies the lower part of the siphon prevents the passage of gases. It should be noted that this device does not have a downward facing chimney. It is fortuitously, as a result of the presence of the siphon, that part of the gas passage duct is directed downward, forming the upstream branch of the "U" constituting the siphon. As explained above, the exhaust gas chimney is pointing upwards.
- the waste incinerator which is the subject of the invention is of the same general type as that described in the document FR-A-1 231 446 cited above.
- It includes a hearth provided with a loading opening, a combustion grate arranged at the bottom of the hearth, an air intake opening, and a chimney for evacuating burnt gases, the mouth of which is connects to the upper part of the fireplace.
- the chimney comprises an exhaust pipe for the burnt gases which is directed downwards and which opens to the outside via its lower end, and, on the other hand, that this tubing is internally equipped with a water diffuser also directed downwards.
- this diffuser fulfills a double function.
- the first of these functions is to create a depression in the hearth relative to atmospheric pressure, which ensures a natural entry of combustion air through the air intake opening and prevents hot gases from leaving through the covers of the loading and cleaning openings of the fireplace, which are not necessarily sealed.
- This depression of the hearth ensures good draft, allowing efficient and complete combustion of the waste.
- the second function of the internal water diffuser is to extinguish the incandescent particles present in the burnt gases, to cool and to wash the fumes, so that the burnt gases escaping from the appliance are not very polluting and cold or lukewarm. .
- the inverted arrangement of the chimney thwarts the exhaust of still hot gases, since these have a natural tendency to rise.
- the tubing has a length greater than or equal to the height of the hearth
- the chimney is made up of four successive sections comprising, from the fireplace to the outside:
- the hearth is double walled, the space between the walls allowing air circulation for the refrigeration of the hearth;
- the water diffuser comprises a hollow body with a chamfered base, and a spraying member with a conical wall, the position of which is adjustable in height.
- the waste incineration installation comprises an apparatus as described above. It comprises means for recovering the water diffused at the outlet of the chimney, for purifying it and for bringing it back to the diffuser according to a closed circuit.
- FIG. 1 is an exploded perspective view of the apparatus
- FIG. 2 is a cross-sectional view through a vertical plane passing through the axis of the chimney of the apparatus of Figure 1;
- - Figure 3 is a detail view, in axial section, of the water diffuser;
- FIGS. 1 and 2 are schematic views which illustrates the operation of an installation according to the invention.
- the waste incineration apparatus, referenced 1, represented in FIGS. 1 and 2 comprises a box 2 of generally rectangular parallelepepedal shape, for example cubic, with double wall, constituting the hearth of the apparatus.
- Its walls, both interior and exterior, are made of sheets of refractory steel sheet assembled by welding.
- the internal faces of the internal walls are coated with a refractory material not shown in FIG. 1 and referenced 26 in FIG. 2. This is for example an assembly of refractory bricks making it possible to obtain a high temperature of the hearth, for good incineration.
- the internal plates constituting the hearth are referenced 20 to designate the horizontal upper wall, 21 to designate the side and front and rear walls, 23 for the bottom wall.
- the external wall elements are designated 40 for the side plates, 41 for the front and rear plates, 42 for the upper plate.
- the box is supported by four feet 22 (only one of which is shown in Figure 1) which allow it to be supported on a plane _S_.
- Appropriate spacers 210 maintain the desired spacing between the inner and outer wall elements, providing a peripheral space into which air can enter from below.
- the upper internal 20 and external 42 plates respectively have an opening 200 and a notch 420 coming in correspondence with the opening 200, to allow the introduction of the waste to be burned in the hearth.
- a cover 43 is provided for closing the opening 200 during use.
- a combustion grate 8 intended to receive the waste to be burned. This is supported by side angles 80 (of which only one is shown in Figure 1).
- the angles 80 are preferably reversible and adjustable in height.
- the front wall of the hearth is provided, at the bottom, with a cover 7 for cleaning the hearth, which is held in place by a cross member 72 and clamping screws 73.
- the combustion air enters naturally through an opening 70 made in the cover 7.
- a sliding shutter 70 makes it possible to adjust the air flow entering the hearth by more or less discovering the opening 70.
- the opening 70 is located below the level of the grid 8.
- an opening 74 fitted with a flap 75 allows the evacuation of ashes and other residues.
- the device is equipped with a chimney 3 for evacuating the burnt gases.
- the tube is a cylindrical tube having the general shape of an inverted "3".
- the tube is formed of sections 30, 31, 32, 33 and 34 fixed to each other by welding.
- the section 30 is a straight sleeve of short length disposed vertically and the base of which passes through circular openings in the plates 20 and 42.
- the sleeve 30 is welded to each of these plates, to open into the hearth.
- a first bend 31 which describes an angular sector of 90 °.
- This elbow is itself connected to a substantially horizontal rectilinear sleeve 32 which extends laterally, towards one of the sides of the hearth. Its length is sufficient for its opposite end to reach beyond one of the side walls 40 of the hearth.
- the sleeve 32 is itself fixed by welding to a second elbow 33 which also describes an angular sector of 90 °, and the mouth of which is directed downwards. To this mouth is welded a tube 34 of vertical axis.
- the length L l of the latter is of the same order of magnitude, and preferably slightly greater than the height L2 of the hearth (see FIG. 2).
- the top of the second elbow 33 has an opening, around which a small sleeve 35 is welded, coaxial with the pipe 34.
- This sleeve receives a system for supplying and diffusing water into the chimney.
- the system comprises a supply duct 5, the end of which carries a fitted mounting sleeve 50 and fixed in the sleeve 35. At its free end is screwed a doubly threaded ring 51 in which a diffuser member 6 is fixed.
- Figure 3 is a detailed view of the diffuser 6. It comprises a hollow body 60 screwed into the ring 51.
- the body 60 has two bores 61, 62 connected by channels 64 allowing the passage of water from the upper bore 61 to lower bore 62.
- the lower bore 62 opens downwards through a divergent conical chamfered wall 63.
- an axial threaded rod 66 In the central part of the body 60 which separates the bores 61 and 62 is screwed an axial threaded rod 66.
- This rod extends downward into the bore 62 and outside the body 60. It receives a spraying member constituted by a frustoconical nut 65, the angle of which at the top of the conical wall corresponds to that of the chamfer 63.
- a spraying member constituted by a frustoconical nut 65, the angle of which at the top of the conical wall corresponds to that of the chamfer 63.
- Nuts 67, 68 which act as locknuts, prevent the screw 66 and nut 65 from being adjusted. The water which is brought by the conduit 5 to the diffuser 6 will therefore pass through the channels 64 to occupy the bore 62 from which it will escape in the form of rain, in a conical jet.
- This rain will descend inside the tubing 34, over the entire length L l.
- the fineness of the water droplets will depend on the passage section corresponding to the gap 620, and therefore on the height adjustment of the member 65.
- a sprinkler ramp 25 supplied with water by a supply duct 250.
- the ramp 25 extends horizontally in the upper part in the central region of the hearth.
- the waste to be burned is introduced into the hearth through the opening 200, and comes to rest on the combustion grate 8.
- the materials are ignited, possibly using an auxiliary fuel for starting the operation.
- the cover 43 being put in place to close the opening 200, the combustion air arrives in the hearth from below the grate, through the adjustable opening 70.
- pressurized water is supplied to the diffuser 6, using an appropriate pump, as symbolized by the arrow G in FIG. 2.
- the water leaves the diffuser 6 in the form of rain droplets which are sprayed at the upper end of the tube 34.
- the depression of the hearth also favors the admission of air, through the opening 70, and makes it possible to obtain an excellent draft, conducive to a complete combustion of all the materials, even slightly inflammable, placed on the grid.
- the smoke stream entering the chimney generally carries glowing particles in suspension. During their downward path in the tubing 34, these particles will be quenched by the water droplets emitted by the diffuser 6 inside the tubing.
- the water droplets also cool and wash the fumes.
- This air for cooling the walls rises towards the upper part of the hearth and is then evacuated by suitable openings, for example by the notch 420 placed above the cover 43.
- this hot air can be captured for subsequent use.
- FIG. 4 schematically represents a waste incineration installation using an apparatus 1 of the type described.
- the chimney 3 opens into a tower 9 for separating the smoke and the water.
- a deflector cone 90 At the base of the tower is a deflector cone 90.
- the washed fumes escape from the tower 9 through a chimney 910, as symbolized by the arrow 3.
- the recycling circuit 900 is equipped with a pump 93 ensuring circulation water taken from tower 9 to bring it to diffuser 6.
- a purification device 91 On this circuit is installed a purification device 91. It is for example a cent ⁇ fugation device which separates the liquid and solid particles.
- a cooling device 92 It is a heat exchanger.
- the water, still lukewarm, is for example exposed to a jet of cold air A produced by a fan.
- Addition of water and treatment products can be added to the circuit, for example in tower 9, as symbolized by the arrows B1 and B2.
- the extinction of the hearth by the ramp 25 can be triggered automatically if the operating conditions become abnormal, for example if the supply of water to the diffuser is done incorrectly.
- the diffuser could for example have two cones 65 placed one above the other.
- Such an apparatus is particularly suitable for maritime applications, in particular for equipping merchant ships.
