Definitions

  • the present invention relates to multipurpose incinerators for burning solid waste or residues and / or liquid effluents.
  • Incinerators already known are composed of a tank or combustion chamber comprising an airlock for introducing solid waste, a fuel burner and means for introducing liquid effluents into the incinerator to burn them or to decompose them by fire. .
  • the prior patent FR-A-2 389 070 describes such an incinerator which includes a particular burner inside which a fuel and polluting liquids can be intimately mixed.
  • This incinerator comprises a double metal tank which delimits an intermediate space in which circulates fresh air which is sucked in by a chimney in which it mixes with the fumes coming from the combustion chamber.
  • US-A-3915104 (Hapgood) describes an incinerator which has a built-in fan which circulates cooling air in the intermediate space between the two walls of the combustion chamber, but this air is not used for suck the fumes and put the combustion chamber in vacuum.
  • An object of the present invention is to provide means which make it possible to use a fan for circulating fresh air in the intermediate space between the two tanks and for simultaneously sucking the fumes without the fumes passing through the fan and while maintaining the combustion chamber in depression.
  • Another objective of the present invention is to provide an incinerator equipped with relatively simple and inexpensive burners which make it possible to vary the quantity of fuel used as a function of the calorific value of solid waste and according to the flow rate and the calorific value of the effluents liquids.
  • the incinerators according to the invention are of the known type comprising a vertical combustion chamber equipped with a grate at the bottom, an airlock for loading solid waste, a smoke evacuation duct located at the top and at least one burner, which combustion chamber comprises two metal tanks which delimit between them an annular space in which fresh air is circulated.
  • An incinerator comprises, at the bottom, a box in which a fan blows fresh air and said annular space communicates, by its lower end with said box and by its upper end with an annular air ejector which surrounds the front end of said smoke evacuation duct and which sucks the fumes by creating a vacuum in the combustion chamber.
  • the upper end of the annular space surrounding the combustion chamber communicates with an evacuation duct in the form of convergent-divergent having a neck and the combustion chamber comprises a smoke evacuation duct. having an open end which is located coaxially in said neck and whose external diameter is slightly less than the internal diameter of said neck and defines therewith an annular space of small radial width which constitutes said annular ejector.
  • the burner fitted to an incinerator comprises a cylindrical duct which opens tangentially into said combustion chamber and which is connected with said box, which duct contains an axial cane for injecting pulverized liquid effluents and several fuel injectors which are each equipped with a nozzle and which are arranged inside said duct and at the periphery of said axial rod.
  • the airlock for loading solid waste from an incinerator comprises an interior door which closes an opening situated in a side wall of the combustion chamber and which is articulated around a horizontal axis situated along the upper edge of said opening and a fixed box which surrounds said loading opening and which comprises a second rectangular opening which is equipped with a bucket holder articulated around a horizontal axis situated along the lower edge of the second opening, which bucket holder comprises an inner wall placed inside said box, an outer wall perpendicular to said inner wall and two side walls in the shape of a quarter of a circle, which are centered on said axis of articulation and which have a radius slightly less than the height of said second opening.
  • the invention results in a new versatile incinerator capable of burning or decomposing both solid and liquid waste by fire.
  • An incinerator according to the invention has the advantage that the combustion chamber is kept under vacuum and its external walls are cooled by a stream of air without the fumes passing through the fan, which prevents rapid wear of the latter. ci under the effect of the temperature of smoke and corrosive gases from the decomposition of waste.
  • the burner fitted to an incinerator according to the invention comprises fuel injectors equipped with a nozzle, which are simple, robust and easy to maintain devices.
  • the disposi tion of the fuel injectors around a central liquid effluent injection rod causes the flames produced by the fuel injectors to surround the pulverized liquid waste which is forced to pass through the flame, which leads to good combustion or decomposition of these.
  • the burner has several fuel injectors which are fed in parallel, which makes it possible to adjust the fuel flow rate according to the calorific value of the liquid effluents and even to stop all the fuel injectors if the liquid effluent has a sufficient calorific value to maintain combustion.
  • Fig. 1 represents a multipurpose incinerator 1 which is installed, for example, on a boat or in a factory to eliminate both solid waste and liquid effluents, for example to eliminate household waste or solid residues from a manufacturing process and at the same time water or sludge laden with suspended matter or residual liquids from a manufacturing process.
  • the incinerator 1 is of the known type comprising a vertical combustion chamber 2 which is equipped with a grid 3 at the bottom, an opening provided with an airlock 4 for the introduction of solid waste, a conduit smoke evacuation 5 which communicates with the upper part of the chamber 2 and with an evacuation chimney.
  • the combustion chamber 2 comprises two metal tanks, an internal tank 6 which is internally covered with a refractory lining 7 and an external tank 8.
  • the two tanks 6 and 8 are concentric and they delimit between them an intermediate annular space 9 in which fresh air circulates which prevents the tank from being brought to a high temperature and does not risk causing burns or fire risks.
  • the incinerator has at its lower part a box 10 which is connected to the discharge duct of a fan 11.
  • the lower end of the annular space 9 communicates with the box 10.
  • the smoke duct 5 is surrounded by a box 12 which delimits around the open end of the duct 5 an annular space 13.
  • the box 12 communicates with the upper end of the annular space 9, so that part of the fresh air blown by the fan flows through the annular space 9 and then through the annular space 13.
  • the annular space 13 forms a air ejector of the so-called parietal type, that is to say an ejector which is located at the periphery of the end of the smoke duct 5 and which sucks the fumes by creating a depression in the chamber 2 which causes an entry of combustion air through the grid 3 which communicates with a lateral air inlet opening.
  • the box 12 is connected to a sheath 12a connecting to a chimney.
  • the fan 11 is used both to circulate fresh air in the annular space 9 and to cause the aspiration of the fumes and their dilution without the fumes passing through the fan and while maintaining the chamber 2 in depression, which makes it possible to introduce solid waste therein through the airlock 4 without risking flame projections to the outside.
  • the incinerator 1 includes a burner 14 which is intended to produce a flame by the combustion of a liquid or gaseous fuel in order to initiate or maintain the combustion of solid waste.
  • the burner 14 also includes means making it possible to inject combustible or non-combustible liquid effluents into the flame to destroy them.
  • the burner 14 comprises a cylindrical duct 15 which opens tangentially into the combustion chamber 2 and which is connected to the air box 10 by a duct 16 provided with a damper 17.
  • the duct 15 contains an axial rod 18 for injecting residues liquids, for example waste water loaded with particles having a variable calorific value according to the applications and ranging for example between 0 and 5000 Kgcal / Kg.
  • the injection pipe 18 comprises an axial duct 18a which is supplied with liquid effluent by a volumetric pump at a constant but adjustable flow rate and an annular duct which is supplied by a duct 18b with compressed gas intended to spray the liquid effluent.
  • the nose of the rod 18 is situated substantially in the plane of the front end of the duct 15.
  • the burner 14 further comprises several injectors 19 of liquid or gaseous fuel which are arranged inside the duct 15, at the periphery of the axial rod.
  • the injectors 19 each have a mechanical spray nozzle at their end and operate without a return circuit.
  • the injectors 19 are very simple injectors, of the type used in low-power domestic boilers. They are supplied in parallel with fuel which is compressed by a pump 20 at a pressure which is for example of the order of 12 bars.
  • the burner 14 comprises three injectors 19 arranged in a triangle around the central rod 18 and the supply circuit of each injector 19 comprises a solenoid valve, which makes it possible to commission any number of injectors 19 according to the quantity of burner waste and its calorific value.
  • liquid effluents have a high calorific value, for example greater than 5000 Kgcal / Kg, it is possible to stop the supply of fuel to all the injectors 19 and to operate only with the axial rod 18.

  • the combustion chamber 2 comprises a smoke evacuation duct 5 which is located inside the evacuation sheath 12, 12a.
  • the front end of the duct 5 is open and it is arranged coaxially in the neck of the convergent-divergent. It has an external diameter slightly smaller than the internal diameter of the neck and defines therewith an annular space of small radial width which constitutes an annular ejector 13.
  • the air which is discharged by the fan 11 into the annular space 9 serves as the working fluid for the ejector and the vacuum which arises at the neck of the Venturi sucks the fumes so that the pressure in the combustion chamber 5 is automatically lower than the pressure in the intermediate space 9.
