Definitions

  • the present invention relates to a system for the thermolysis treatment of solid products, the rejection of which is harmful to the environment.
  • Document FR-A-2.106.844 discloses a garbage processing device comprising a succession of zones of increasing temperatures (up to 800-1300 ° C) which are passed through the garbage after packaging. in a porous coating material; this garbage is gradually rid of its water vapor and then pyrolyzed.
  • this solution requires still high temperatures, this mistletoe still leads to rapid wear and a high operating cost.
  • the object of the invention is to overcome the aforementioned drawbacks by allowing treatment by thermolysis at medium temperature, for example around 600 ° C. by allowing continuous control of decomposition products.
  • the invention thus provides a system for the treatment of solid products, the rejection of which is harmful to the environment, comprising a reactor successively integrating a dehydration zone and a thermolysis zone, characterized in that this reactor comprises downstream of the zone thermolysis, a cooling zone and in that the dehydration zone is provided with a sealed entry door, the cooling zone is provided with a sealed exit door, and airlocks isolate the thermolysis area, d on the one hand with respect to the dehydration zone, on the other hand with respect to the cooling zone so as to limit the entry of air into the thermolysis zone during the introduction of the products and during the extraction of residues, this thermolysis zone being provided with a gas extraction line thanks to which it is under vacuum.
  • Figure 1 shows the block diagram of the system and Figures 2 to 4 show some constructive details.
  • the system according to the invention comprises a reactor integrating in a single device a chamber 1 for introducing the products to be treated and in which these products undergo dehydration, a thermolysis chamber 2 in which the products, partially or totally dehydrated, are brought at the thermal decomposition temperature, for example around 600 ° C (typically between 400 ° C and 750 ° C) and a cooling chamber 3 where the solid residues from the heat treatment are brought to an ordinary temperature.
  • a reactor integrating in a single device a chamber 1 for introducing the products to be treated and in which these products undergo dehydration, a thermolysis chamber 2 in which the products, partially or totally dehydrated, are brought at the thermal decomposition temperature, for example around 600 ° C (typically between 400 ° C and 750 ° C) and a cooling chamber 3 where the solid residues from the heat treatment are brought to an ordinary temperature.
  • thermolytic transformation in the reactor is advantageously carried out in the total absence of free oxygen at an average temperature of 600 ° C.
  • the decomposition products - incondensable gases, heavy hydrocarbons, coal - are continuously monitored at the outlet of the system and are optionally recycled for further treatment.
  • the chambers are insulated from one another in a substantially sealed manner, by guillotine doors 23 actuated by jacks; the door between chambers 1 and 2 and the door between chambers 2 and 3 are movable vertically in watertight housings, the crossing of the lifting cylinders being by stuffing box.
  • watertight doors are provided at the entrance to chamber 1 and at the exit from chamber 3 whereby the dehydration 1 and cooling zones are, at will, isolated from the outside and / or thermolysis zone 2; they can be movable vertically or horizontally or around a joint according to the dimensions of the reactor, the space available and the free choice of the designer.
  • Chambers 1 and 2 of the reactor are lagged (item 27) to limit heat loss.
  • Chambers 1 and 2 are provided with heating means of all suitable known types, two examples of which are given under references 4 and 5.
  • the temperature of chamber 2 is, for example, maintained at around 600 ° C. while that of chamber 1, lower, is maintained above 100 ° C., for example around 120 ° C.
  • Catalytic radiant panels 4 provided with built-in resistors 25 intended to heat them up to allow the catalytic oxidation phenomenon of feed gas, are shown on the ceiling of chambers 1 and 2 but can also be placed on the side walls. These panels are placed in watertight housing vis-à-vis the outside.
  • the detail of FIG. 4 shows the principle of fixing a panel 4 on the internal wall of the reactor and the position of a seal identified 26 put in place to force the gaseous supply mixture (preferably oxygen, pyrolysis gas) to pass through the catalytic panel 4 where it is oxidized.
  • Chamber 3 can be equipped with a system (not shown) for cooling solid residues and recovering heat by heating the gases which supply the catalytic radiant panels.
  • Electric resistors 5 are supplied from a transformer 6; these resistances are here represented inside the reactor, glued to the wall (but can be put outside), the electrical supply being made by using watertight bushings.
  • Chamber 2 is kept under vacuum, typically at a pressure less than or equal to 800 mbar, or even 500 mbar. Preferably, the same pressure prevails in chambers 1, 2 and 3.
  • the gas mixture extracted from chamber 2 goes into a gas washer 9 which opens into a settling block 13 and is supplied with cold water by a basin 14 where the water at the outlet of the settling tank 13 is treated by conventional methods of water chemistry. Hydrocarbons condensed and the carbon separated from the aqueous phase in the tank 13 are sent to a storage tank 17 where they will be taken up for use.
  • the non-condensed gases at the outlet of the tank 9 are sucked in by a pumping group 10, the discharge of which flows into a washing tank 11 where the carbon dioxide is eliminated by adding potassium carbonate, for example, in the water coming from the tank. 14.
  • the purified gas is compressed by the compressor 12 and stored in a tank 16.
  • This compressed gas is here sent to the catalytic radiant panels 4 after passing through a mixer 15 which also receives compressed air from any source at 18, or alternatively, depending on the application, pure oxygen coming from a outdoor storage.
  • the gas mixture passes through a recuperator 7 where it is heated in order to improve the thermodynamic balance of the catalytic oxidation.
  • FIG. 1 indeed shows an exit of the catalysis gases from the chamber 1; these gases, mainly composed of carbon dioxide and water vapor from dehydration and catalytic oxidation, pass through the recuperator 7 where they are cooled. They are sucked up by a pumping group 8, the discharge of which flows onto a chimney 19.
  • FIG. 2 shows a carriage 20 in which the products to be treated are placed; the carriage passes from one room to another via a rack and pinion system 21.
  • a drive shaft 22 ensures the synchronized movement of the carriages.
  • the gases are extracted from the chambers 1 and 2 by flues 24 located at the end of the chambers and on the floor so as to entrain the coal in the gas flow.
  • Gas washers are a product of classical chemical engineering.
  • the system according to the invention allows excellent energy recovery with the possibility of storing the recovered energy in the form of coal and hydrocarbons, possibly of transporting it for consumption at the appropriate place and time.
