Abstract
The invention relates to an industrial and/or household waste treatment method and to an industrial and/or household waste treatment installation (1). According to the invention, the method is characterised in that it consists of, in particular, the loading of the waste into numerous pierced containers (20), thermolysis of the waste in the containers (20) being conveyed into a pyrolysis oven (12); emptying of the containers (20) into a separation tank (18) in order to separate the products formed by the thermolysis; and treatment of the separated products.
Claims32
A treatment method for industrial and/or household waste, characterized in that it notably comprises loading the waste into a plurality of pierced containers, pyrolysis of the waste in containers by conveyance into a pyrolysis furnace and one or more treatments of the products resulting from this pyrolysis, the pierced containers having at least one part with a shape permitting these containers to roll on themselves in the pyrolysis furnace, thus producing the movement and the turning of the containers by gravity of their contents;
- a drying of waste in containers before pyrolysis by conveyance into a dryer heated by the residual heat from the means used to heat the pyrolysis furnace;
- a recycling of a portion of the gases issued from the pyrolysis as a fuel, to obtain the heat necessary for pyrolysis or to supply at least an energy-recovery means, or both;
- and
- evacuating the pyrolysis gases into evacuation conduits whose temperature is particularly controlled by heating or cooling the conduits, so as to prevent the escape of polluting gases.
A treatment method for industrial and/or household waste, characterized in that it notably comprises loading the waste into a plurality of pierced containers, pyrolysis of the waste in containers by conveyance into a pyrolysis furnace and one or more treatments of the products resulting from this pyrolysis, the pierced containers having at least one part with a shape permitting these containers to roll on themselves in the pyrolysis furnace, thus producing the movement and the turning of the containers by gravity of their contents, further characterized in that the gases resulting from pyrolysis lose a part of the pollutants that they contain upon contact with filtering elements or absorbent elements containing activated charcoal, positioned after the gases leave this furnace, or both, filtering elements comprising motorization elements that contain activated charcoal and assure the rotation of waste containers by a rack system.
A treatment for industrial and/or household waste, characterized in that it notably comprises loading the waste into a plurality of pierced containers, pyrolysis of the waste in containers by conveyance into a pyrolysis furnace and one or more treatments of the products resulting from this pyrolysis, the pierced containers having at least one part with a shape permitting these containers to roll on themselves in the pyrolysis furnace, thus producing the movement and the turning of the containers by gravity of their contents, the method further comprising, after pyrolysis, a washing of the carbon-containing solids resulting from pyrolysis of the waste contained in containers, this washing being carried out by passage into a liquid tank.
A treatment method for industrial and/or household waste, characterized in that it notably comprises loading the waste into a plurality of pierced containers, pyrolysis of the waste in containers by conveyance into a pyrolysis furnace and one or more treatments of the products resulting from this pyrolysis, the pierced containers having at least one part with a shape permitting these containers to roll on themselves in the pyrolysis furnace, thus producing the movement and the turning of the containers by gravity of their contents, the method further including a treatment of waste after pyrolysis that comprises the following steps:
- separation by gravity in a tank for separation of carbon-containing solids, on the one hand, and metals, minerals or metal oxides, on the other hand;
- pumping of the carbon-containing solids into the separation tank;
- filtering of these carbon-containing solids on a band filter to introduce the waster onto ion-exchange resins.
A plant for the treatment of industrial and/or household waste, characterized in that it comprises a pyrolysis furnace comprising means for conveying pierced containers containing waste to be treated, separation means to separate the products formed in containers by pyrolysis and treatment means for these separated products, the containers having at least one part with a shape permitting these containers to roll on themselves in the pyrolysis furnace, thus bringing about the movement and the turning of these containers by gravity of their contents, wherein a container receiving the waste is hollow and of rotating cylinder shape and comprises two toothed crown gears surrounding its axis and situated at both ends of container, and holes pierced in the base sections of container.
A plant for treatment of industrial and/or household waste, characterized in that it comprises a pyrolysis furnace comprising means for conveying pierced containers containing waste to be treated, separation means to separate the products formed in containers by pyrolysis and treatment means for these separated products, the containers having at least one part with a shape permitting these containers to roll on themselves in the pyrolysis furnace, thus bringing about the movement and the turning of these containers by gravity of their contents, the plant further comprising at least one extraction chamber able to receive activated charcoal polluted by the filtering of pyrolysis gases, or carbon-containing solids from pyrolysis, or a combination of these elements, and is to be filled with a mixture based on carbon dioxide, and having pumping means able to bring the carbon dioxide in the chamber to its supercritical state, so as to extract the solid carbon present in the chamber, then to evacuate this supercritical carbon dioxide towards an expansion chamber and by leaving metals or pollutants unextracted by the carbon dioxide in the extraction chamber.
A plant for treatment of industrial and/or household waste, characterized in that it comprises a pyrolysis furnace comprising means for conveying pierced containers containing waste to be treated, separation means to separate the products formed in containers by pyrolysis and treatment means for these separated products, the containers having at least one part with a shape permitting these containers to roll on themselves in the pyrolysis furnace, thus bringing about the movement and the turning of these containers by gravity of their contents, wherein second containers or oxidation containers are loaded with a certain quantity of ashes containing pollutants or heavy metals mixed with a water-based mixture, the plant comprising means for bringing the pressure and temperature of this mixture above the triple point of water, or to the point where the water is in a supercritical state, in order to oxidize the heavy metals or degrade other pollutants contained in these ashes.
