Definitions

  • the field of the invention is that of eliminating sludge or other pasty waste of the same type, such as greasy waste, and in particular sludge of the type originating from industrial processes or from purification plants for drinking water. or wastewater.
  • the invention relates to a system for injecting sludge or other pasty waste of the same type to be incinerated in an incineration furnace, as well as a corresponding method and furnace.
  • the invention finds particular application in combi ovens of household refuse (or other urban or industrial waste) and of sludge and / or greasy waste. It applies to ovens with very different types of combustion (for example with fixed or mobile incineration hearth, grates, rollers, fluidized bed, etc.).
  • Sludge and in particular that from the dewatering workshops of wastewater treatment plants, generally has a non-negligible content of organic materials that are difficult to biodegrade. They therefore constitute a nuisance for the environment, which should be eliminated.
  • Sludge due to the increasing number of water treatment plants, there is an increasing amount of sludge to be treated.
  • the injection of sludge into the combustion chamber of a household refuse incineration furnace is generally carried out continuously, in the form of a cylinder of mud.
  • the sludge does not disperse in the combustion chamber during their injection and their combustion is therefore not optimal.
  • the unburnt contents of bottom ash and fly ash from the incineration of the household waste / sludge mixture can become higher than the maximum values imposed by legislation (for example, a maximum of 5% of unburnt in bottom ash).
  • the sludge is not distributed with household waste evenly. There therefore occurs phenomena of sub-cooling or overheating of the combustion chamber, depending on whether the incinerated mixture contains more or less sludge. These phenomena can disturb the operation of the oven, or even cause combustion to stop.
  • variable quality of the sludge to be incinerated in particular depending on the quantity of dry matter it contains and its calorific value, can also cause overheating or sub-cooling phenomena causing defusing of the boiler.
  • the invention particularly aims to overcome these various drawbacks of the state of the art.
  • one of the objectives of the present invention is to provide a system for injecting sludge to be incinerated in a mixed waste incineration oven household and dehydrated sludge, this system making it possible to avoid stopping the oven by crossing the high temperature limits (in the case of overheating) or low (in the case of under cooling).
  • the invention also aims to provide such a system which does not increase the rate of unburnt in bottom ash, nor the rate of unburnt in fly ash.
  • Another object of the invention is to provide such a system which does not create significant new labor requirements in terms of the daily operation of the oven or in terms of maintenance and upkeep of the heating system. injection itself.
  • a complementary objective of the invention is to provide such a system that can be implemented with any type of oven (including an oven specifically designed to incinerate sludge), while allowing optimal combustion of the injected sludge.
  • Another object of the invention is to provide an optimized method for operating such a system.
  • a system for injecting sludge to be incinerated, or other pasty waste of the same type, in an incineration oven said furnace comprising an incineration hearth onto which said household waste is dumped in order to be incinerated, the system comprising means for injecting said sludge to be incinerated into the furnace, disposed essentially above said incineration hearth so as to allow a sludge supply to said bottom at least partly by gravity, said injection means being provided with means for spraying the sludge during their injection into the furnace.
  • the injection means comprise an injection body forming a spraying chamber comprising a sludge supply inlet, and an outlet nozzle for injecting sludge into the furnace, said chamber being traversed by a gas injection tube, such as air or water vapor, under pressure, the end of which is provided with a diffuser in the region of the nozzle of said chamber, said pressurized gas injection tube cooperating with means for moving the diffuser relative to the injection nozzle of the chamber, so as to allow adjustment of the spraying of sludge and / or cleaning of said chamber.
  • a gas injection tube such as air or water vapor
  • the sludge is divided into droplets or pancakes before being dispersed on the incineration hearth.
  • This has an important advantage, especially when the incineration oven is a combi-type oven used to incinerate something else, in particular household waste, or other waste.
  • This allows optimal combustion of the sludge by creating an exchange surface significant and a homogeneous distribution of this sludge on the waste resting on the incineration bottom.
  • This optimal sludge combustion not disturbing that of waste, does not increase the unburnt content of bottom ash and smoke.
  • the droplets or slabs of sludge obtained by spraying must be neither too fine nor too coarse.
  • the percentage of sludge injected in relation to the waste, as well as the dryness of this sludge are variable and chosen according to the desired objective, for example taking into account the thermal availability of the day, namely either to eliminate a maximum of sludge, or to supply l 'energy.
  • the sludge by being injected continuously and burning almost perfectly, does not create any problem of overheating or subcooling. It suffices that the waste / sludge mixture remains self-combustible.
  • said incineration hearth comprises at least two successive distinct zones, namely a combustion zone and a finishing zone, and said injection means are located essentially above said zone combustion.
  • said incineration hearth comprises at least three successive distinct zones, namely a zone of drying, a combustion zone and a finishing zone, and said injection means are situated essentially above said drying zone and said combustion zone.
  • the sludge is distributed over the zone or zones of the incineration hearth allowing optimum combustion of this sludge.
  • the duration and the temperature must be sufficient for the sludge, after homogeneous distribution by spraying, to be completely burnt.
  • said injection body is mounted on a ball joint and cooperates with at least one telescopic rod for adjusting the inclination of said injection body by rotation around said ball joint.
  • This adjustment of the spraying of the sludge is generally done in conjunction with that of the injection pressure in the spraying means, these values being adjusted for example at start-up.
  • said injection tube is covered at least partially with a protective sheath.
  • This sheath makes it possible to limit the abrasion of the injection tube and the attachment of the tow.
  • the system of the invention can be adapted to any type of oven and the sludge can be injected at the right place, that is to say on the hearth, in particular avoiding any projection of sludge on the walls of the chamber. combustion.
  • said chamber is provided with a cleaning fluid inlet.
  • said cleaning fluid inlet is located at the level of the sludge inlet, so as to allow cleaning of the entire chamber before the cleaning fluid is discharged through the injection nozzle.
  • the system includes means for controlling the internal temperature of the furnace, controlling the flow of injected sludge.
  • the combustion of sludge is enslaved to that of household waste.
  • the sludge injection rate is slaved to the temperature of the furnace.
  • the system comprises means for controlling a movement back and forth from the tube for injecting gas under pressure into the spraying chamber, in order to prevent any blockage of the chamber by the sludge.
  • the injection tube and the diffuser allow cleaning of the spray chamber.
  • the injection means also cooperate with a sweeping air supply duct preferably provided near the diffuser and thus making it possible to protect the latter from the radiant heat of the oven.
  • the invention also relates to a mixed incineration oven for household waste and sludge provided with a system as presented above.
  • the invention also relates to a method of operating a system as presented above, this method comprising an operating cycle starting with a start-up phase in which the supply of sludge to the spray chamber is carried out after establishment of a nominal gas injection regime such as pressurized air, and ending with a stop phase in which the interruption of the supply of sludge to the spraying chamber precedes the establishment of a low regime injection of pressurized gas, said stopping phase being preceded by a cleaning phase of the spraying chamber, in which a cleaning fluid passes into the spraying chamber and is evacuated by the sludge injection nozzle in the oven.
  • a nominal gas injection regime such as pressurized air
  • the gas sweep is therefore maintained, with a low pressure value in order to prevent any risk of deterioration of the injection means by radiation.
  • the cleaning phase is a generally brief and infrequent operation, for example two minutes every six hours.
  • the system of the invention can advantageously be used for the incineration of sludge or other pasty waste such as greasy waste from a wastewater treatment plant. wastewater treatment.
  • said sludge undergoes a preliminary treatment of at least partial dehydration before their injection for incineration.
  • the invention therefore relates to a sludge injection system intended to be used in a mixed incineration oven for household waste and sludge.
  • Such an oven is in fact a conventional oven for incinerating household waste to which a sludge injection system is added.
  • a grapple 1 attached to an overhead crane 2 makes it possible to seize household waste in a storage pit (not shown) and to discharge it (a) into an inlet hopper 3. This household waste arrives (b) on a floor d incineration 4.
  • clinkers 13 are obtained which are collected (c), via an outlet hopper 8, in a bucket 9 (or any other storage means) in order to to be evacuated.
  • outlet hoppers 10, 11, 12 can also be placed under the different zones 5, 6, 7 of the incineration hearth 4, so as to recover (d), (e), (f) the bottom clinkers passing through this sole 4.
  • the incineration of household waste mainly in the combustion zone 6, generates not only bottom ash 13 but also smoke containing fly ash.
  • these fumes pass (g) through an energy recovery boiler 14.
  • part of the fly ash 17 is recovered (h) in a bucket 15 and the resulting fumes undergo (i) a new treatment, for example in an electro-filter 16.
  • This electrofilter 16 makes it possible to recover (j) fly ash 17 while the filtered fumes are discharged (k) through a chimney 18.
  • the invention therefore consists in injecting sludge into this furnace, without substantially disturbing the thermal equilibrium of the furnace, or even the operating balance of the furnace (a household waste incineration furnace which in principle produces energy under vapor or even electricity sold to a customer).
  • the sludge generally comes from a wastewater treatment plant and has undergone a dewatering treatment, for example with mechanical means of the band filter or centrifugal decanter type. These dehydrated sludges have a dryness of, for example, between approximately 13 and 40% by mass of free water, typically between 20 and 30%. It is subsequently considered that the sludge is dehydrated. However, it is clear that the invention relates to the incineration of all types of sludge.
  • the sludge injection system comprises a buffer silo 19, withdrawal means 20, a feeding hopper 21 and injection means 22.
  • the sampling means 20 for example consist of a volumetric pump with thick material.
  • the dehydrated sludge, stored in the buffer silo 19, is removed by this positive displacement pump 20 and supplied to the injection means 22 without risk of entrainment of air pockets.
  • the injection means 22 are arranged on a wall 24 of the furnace (the roof or the side walls), so as to allow a supply of sludge to be incinerated, by gravity, from the incineration hearth 4. More specifically, the sludge is injected (1) onto the household waste bed resting on this hearth 4. Thus, the sludge is co-incinerated with household waste.
  • these injection means 22 are provided with spraying means.
  • the sludge arrives on the sole in the form of droplets or pancakes. Sludge dispersion is optimized and caking is avoided due to the water. This allows drying and complete combustion of the sludge by increasing the exchange surface between the fuel (i.e. the sludge) and the oxidant (i.e. the oxygen in the air ) in the combustion chamber. Consequently, the operation of the oven is not disturbed (no overheating or sub-cooling), without appreciable influence on the rates of unburnt in the bottom ash 13 and in the fly ash 17.
  • injection means 22 are placed overhanging the combustion zone 6. It is clear that these injection means 22 can also be placed overhanging the drying zone 5.
  • the injection means 22 constitute a single injector
  • the invention is not limited to this embodiment but also relates to the case where there is a plurality of injectors.
  • a person skilled in the art is capable, in this case, of choosing the number of injectors required as well as the spacing between two successive injectors, depending in particular on the flow rate and the nature of the sludge injected, on the surface of the sole d 4, etc ...

  • a gas at low pressure for example air
  • the tube 26 can be moved longitudinally inside the chamber 25 thanks to these displacement means 29, which makes it possible to modify the opening angle of diffusion of the droplets or slabs of sludge.
  • Such longitudinal displacement also allows the chamber to be cleaned if necessary.
  • These displacement means consist, for example, of a wheel connected to the tube 26 to be used manually, or else a motorized device for driving the tube, advantageously with position memorization. According to the back-and-forth movement, the diffuser, in the lower lower position, protrudes from the nozzle, which allows effective cleaning of the chamber.
  • the injection means 22 are mounted on orientable means 30.
  • These means 30 consist of a ball joint 35 on which the injection body 25 is mounted and telescopic rods for adjusting the inclination of the injection body 25 relative to the hearth 4 of the furnace.
  • the means 30 make it possible in particular to precisely regulate the positioning of the injection means before the implementation of the oven and thus to optimize the operation of these.
  • the outlet nozzle 33 which is here profiled, does not completely pass through the wall 24 of the furnace, which makes it possible to avoid heating and drying of the sludge to be injected by thermal transfer into the injection body 25.

  • This process for regulating the operation of the oven which can be carried out manually or else be controlled by the automatic control means 37 (if these receive the internal temperature information of the oven), comprises a step of controlling the sludge flow at internal oven temperature.
  • the quantities of sludge that can be injected into a mixed household waste / sludge oven depend on local constraints. Thus, for an oven with an incineration capacity of 100 T / day of household (wet) waste, provision can be made to incinerate 10 to 20% of dehydrated sludge between 20% and 30% of dryness, i.e. 10 to 20 T / day of wet sludge. These values are however only illustrative, and can be revised up or down, depending in particular on the main objective of the oven. In certain cases, it is possible to go as far as providing a mass flow rate of sludge of the order of that of household waste, or even higher.
  • Prototypes of the injector were produced and tested, and made it possible to validate the effectiveness of the invention.
  • the prototype presented a spraying chamber with an internal diameter of approximately 80 mm, over a useful length of approximately 300 mm.
  • the injector outlet nozzle had a diameter of the order of 50 mm. It was possible to spray on site with this injector mud flow rates of the order of 400 to 1600 kg / h, by injecting air at a flow rate of 20 to 100 Nm3 / h, under a pressure of 1 to 3 bars about.
