Definitions

  • the present invention relates to a method and a incinerator for environmentally friendly incineration hospital waste and other solid waste containing fuel.
  • Waste disposal must ensure total incineration of fuel at high temperature, non-combustible residues and fumes to be free from germs, hazardous compounds and odors.
  • Most of the waste hospital is cremated with household waste in incineration plants. This process has the disadvantage of presenting a great risk of contamination during waste transportation contaminated dangerous, or to incur costs high disinfection before transport.
  • EP-A-0 251 269 describes a method and a apparatus for gasifying solid fuel then burn gaseous gasification products.
  • a gas generator for gasifying fuels solids such as wood, coal, fuels in briquettes, household waste etc ... is followed by burners for the combustion of gaseous products directly after the gasification.
  • the air supplying the gasification zone and the burner is heated with heat given off gasification course. Air heating is ensured by passing primary air and air secondary through passages in a multiple wall of the gasification chamber.
  • FR-A-2 649 782 describes a method intended for exclude environmental pollution, independently operator competence.
  • the ignition stages, pyrolysis, combustion and cooling are ensured in sequence under continuous automatic piloting.
  • the temperature is regulated by automatically controlling the air flow rate and operation of additional gas burners in rooms corresponding to the incinerator. So the overload driven by the introduction of a new batch of waste in the oven is prevented.
  • the purpose of this process is main drawbacks of consuming a lot of energy, to require a complex installation, as well as a additional fuel (natural gas) to maintain the pyrolysis and combustion.
  • US-A-3,918,373 describes the treatment of waste solids with primary combustion and combustion secondary.
  • the fumes produced by combustion secondary go through heat exchangers which heat the air for primary combustion. This process is complex and relatively inefficient for activate gasification of low-power waste calorific.
  • DE-C-3 335 537 describes an apparatus for pickling their lacquer objects that are placed in an enclosure including the outer face is exposed to the through gas flow a post-combustion chamber following a chamber combustion equipped with an air inlet and a burner combustible.
  • the object of the present invention is to ensure ecological incineration of hospital waste and other waste containing fuel, minimizing external heat supply while ensuring stable operation for a wide range of compositions and properties of waste, including wet waste.
  • a incinerator for implementing the method, comprising a gasification chamber, to contain a first component consisting of waste to be incinerated, means for introduce a gasification agent as a second component in said gasification chamber, a chamber afterburner, means of fluid communication between the gasification chamber and the post-combustion chamber, so as to introduce into the post-combustion a third component consisting of gaseous products from the gasification chamber, admission means for introducing into the post-combustion a fourth component consisting of a gas secondary oxidant, and means for transferring heat from the afterburner to at least one part of at least one of said components upstream of the post-combustion chamber, characterized in that the means for transferring heat includes a wall heat conductor separating the post-combustion chamber a gasification zone of said chamber gasification.
  • heat generated by the step of afterburner is used to heat directly a wall of the gasification chamber. So the heat transfer takes place with a minimum of losses at all the components involved in the process of gasification, and the chamber wall becomes a means by which the heat arrives.
  • the heat generated by the post-combustion process is directly used to promote reliable maintenance of the whole process even with power waste relatively low calorific. This avoids as much as possible the need for additional heating capacity.
  • additional heat in the case of very low-power waste heat, especially wet waste, can be intervene such additional heat, preferably by regulating the additional thermal power in such a way to maintain a minimum gasification temperature and / or post-combustion.
  • the agent gasification and secondary air which supply the gasification and post-combustion chambers, respectively, or fractions of these when processes relatively high calorific waste dry are preheated by recovering the heat from the fumes generated in the post-combustion chamber. This recovery is carried out by heat transfer to through walls of gas conduits and / or walls of bedroom.
  • the contact between the wall of the gasification and post-combustion products can particular be assured by arranging the room gasification so that the region where the area is located gasification at least partially protrudes into the post-combustion chamber.
  • Gasification and post-combustion processes are controlled by regulating the consumption of the gasification and secondary air and / or redistributing the gasifier and the secondary air between corresponding intake ports, depending on temperatures in the gasification zone and in the post-combustion chamber. Temperatures are maintained within a range whose lower limit is defined by the need to avoid the release of compounds organic, including dioxynes, in dangerous concentrations. The upper limit of temperature is in particular determined by the suitability of the materials constituting the incinerator for resist heat. When the temperature in the gasification zone tends to exceed the limit prescribed, the feed rate of the agent is reduced preheated gasification to reduce the proportion of gasifier preheated in the total gasifier flow.
  • the incinerator must then be equipped a control device connected to probes for measure the temperature in the gasification chamber and in the post-combustion chamber, and to means corresponding, such as valves or fans speed-controlled, controlling flow rates corresponding supply and distribution of the gasifier and secondary air to through the intake ports of the the incinerator according to these temperatures.
  • a control device connected to probes for measure the temperature in the gasification chamber and in the post-combustion chamber, and to means corresponding, such as valves or fans speed-controlled, controlling flow rates corresponding supply and distribution of the gasifier and secondary air to through the intake ports of the the incinerator according to these temperatures.
  • the process can use air as a gasification.
  • we can also inject steam into the gasifying agent of way to reduce the temperature in the area of gasification. The heat needed to produce the steam can be recovered in the fumes.
  • Successive movement of waste to the area gasification can be obtained by gravity of waste and be favored by a design and a size appropriate gasification chamber, for example by making the gasification chamber flared towards the low, for example in a cone.
  • this displacement can be ensured for example by a kind of agitator.
  • the volume of the post-combustion chamber is chosen so that when the incinerator is operating at its nominal capacity, the retention time of smoke in the room is higher than standard time required and takes place under a temperature and oxygen concentration higher than the values prescribed standards, these retention times, standard temperature and concentration being determined with a view to certain decontamination of the fumes.
  • Incineration of waste containing components dangerous, e.g. chlorine or sulfur can be further supplemented by a purification of the smoke from the post-combustion chamber and / or pyrolysis gases withdrawn from the gasification chamber to extract harmful gases using known techniques, for example by passing the gaseous products to through one or more layers of particles of limestone or other absorbent material and neutralizing these pollutants. If the purification step concerns pyrolysis gases, for example pass these through a conduit containing said materials and connecting the gasification chamber to the post-combustion chamber.
  • the afterburner can be subdivided into separate volumes connected in series so let the smoke pass through them successively.
  • Mon of these volumes is preferably arranged in a cyclone, the conduit leading to this volume being arranged to ensure there a circular gas flow. Such a cyclone dust the gases.
  • the process can be implemented continuously.
  • the incinerator can be equipped with means for charging continuously or intermittently new waste into the gasification chamber and discharge the ashes and other incombustibles during the operation of the incinerator.
  • the temperature is not high that in the region of the gasification zone, such loading and unloading can be done by known means, for example by loading waste by through an air lock.
  • the supply of gasification is redistributed so that internal surfaces of the gasification chamber are heat treated for disinfection.

  • a draw assist device for example a extractor fan or ejector.
  • the process described is less sensitive to variations in the composition and properties of the waste, and increases significantly the possibilities of dealing with waste with low calorific value, high content ash and very wet, with which due to small amounts of heat released, gasification self-sustaining is impossible without such preheating or additional heat output.
  • the incinerator in Figure 1 includes a chamber vertically elongated gasifier 1 having a upper opening which is normally closed by a cover 21 or by a device allowing the continuous or discontinuous loading of waste 22 during the operation.
  • the cover is open, or thanks to such a loading device, the waste 22, such as hospital waste contained in disposable plastic containers, can be introduced into the gasification chamber 1.
  • a lower part 24 of the gasification 1 is defined by a perforated wall with through which the gasification chamber 1 is in fluid communication with an afterburner 5, which in turn is in communication fluid with the outside through a chimney 23 for smoke.
  • Part 24 projects to the interior of the post-combustion chamber 5. The wall defining part 24 thus separating inside the gasification chamber 1 with the interior of the afterburner 5 is conductive of heat.
  • Part 24 of the gasification chamber is fitted with an intake port 3 for a gasification, more particularly air with possible addition of water vapor in the example.
  • Electric heating means 12 are mounted in the vicinity of part 24 of the gasification, either in the post-combustion chamber 5 in the vicinity of a perforated part of the wall defining part 24, either in the conduit gasifier adductor just upstream of the inlet 3.
