Definitions

  • the present invention relates to a gasification process and a gasifier for the treatment of large vegetable matter.
  • De Lacotte gasifiers have been known for a long time, for example De Lacotte gasifiers. These consist of a tower loaded from above with the materials to be treated and at the base of which the ash and the gases produced are recovered, the materials successively undergoing drying, pyrolysis and gasification.
  • Gases are recovered at the top of the gasifier, mixed with combustion air, and the very hot gases produced are reinjected into the gasifier substantially at the limit of the pyrolysis and gasification zones. Part of the gases reinjected back into the gasifier - ensuring pyrolysis and drying and taking care of tars produced by pyrolysis, these tars being removed by cracking after mixing with combustion air. The other part of the gas descends into the gasifier and ensures gasification.
  • a gasifier which comprises: a treatment chamber having a rear end and a front end; a device for supplying the chamber with materials to be treated situated at the rear end of the chamber; a mechanical drive device for advancing the materials to be treated between the rear end and the front end of the chamber; a discharge opening formed in the lower part of the chamber at the front thereof; an outlet for gases produced by gasification; a hot gas generator in front of the natural slope of materials contained in the chamber; and a recycling duct for recycling at the front of the chamber gases withdrawn through an outlet situated at the rear of the chamber, a gasifier in which, according to the invention, a suction device is placed in the duct recycling to establish a forced circulation of gases through the bed of materials and to recycle gases.
  • the oxidizing gas used can be air or oxygen.
  • oxygenation gasification with a view in particular to producing synthesis gas causes temperatures such that the ashes of plant materials, including peat, inevitably melt in the gasification zone, their melting temperature being approximately 800 ° C.
  • An advantage of the gasifier according to the invention is that in the case of combustion with air or with oxygen, the combustion gases are not injected directly into the mass of materials, but into a space free located at the front of the slope of materials and authorizing their dilution before injection.
  • the gasifier represented in FIGS. 1 to 4 essentially comprises a horizontal treatment chamber 10, a supply device 20 for supplying the chamber 10, at its rear end 10a, with materials to be treated, a feed device 21 for advancing the materials to be treated through the chamber 10, a generator 30 for supplying hot gases to the chamber 10 at its front end 1 Ob, and a recycling device 40.
  • the chamber 10 has the form of a horizontal tunnel whose side wall 11 is made of refractory material and which is extended, at the rear, by a supply chamber 22 and closed, at the front, by a front partition 1 Oc.
  • a first outlet 12 provided with a grid 12a
  • a second outlet 13 provided with a grid 13a and a discharge opening 14.
  • the outlet 12 is formed at the rear end of the floor 11 a, or in the immediate vicinity of this rear end.
  • the outlet 13 is the outlet for gases produced by the gasifier; it is formed in the middle part of the tunnel or slightly on the front side of it.
  • An outlet pipe 18 is connected to the outlet 13 and opens, at 18a, towards the rear of the gasifier, in a compartment 13b situated under the grid 13a.
  • the opening 14 is formed over the entire width of the floor 1 a at its front end. It communicates, via a vertical duct 15, with a tank 16 which is located below the chamber 11 and where the ashes are collected. materials treated in the gasifier.
  • a water seal shown diagrammatically at 17 is provided to compensate for the difference in pressures prevailing outside and inside the gasifier when the latter is in operation.
  • the supply chamber 22 is surmounted by an airlock 23 for admitting the materials to be treated.
  • a pusher or piston 21 can slide horizontally in the chamber 22 over the entire length of the latter.
  • the piston 21 is provided with a cap 21 fixed on its front face, overhanging on it.
  • the piston When the piston is in its rear extreme position (in broken lines in FIG. 2), the content of the airlock 23 can be introduced into the chamber 22.
  • the advance of the piston 21 is then controlled at a constant and slow speed equal to that to which the heat treatment of the materials is carried out in the chamber 10.
  • the materials to be treated when freshly introduced tend to rise upwards. However, this rise is limited by the cap 21a and there can be no jamming of materials to be treated between the front face of the piston and the lower front edge 23a of the airlock 23, jamming which would block the advance of the piston.
  • the piston When the piston is in its extreme front position (shown in solid lines in FIG. 2), it is quickly brought back to the rear position to allow a new loading of the chamber 22.
  • At the front of the chamber 10 opens at least one injector 31 of oxidizing gas, for example oxygen or combustion air.
  • injectors 31 Preferably, several injectors 31 form a horizontal row, at a level situated immediately above that of the floor 11 a.
  • The, or each, injector 31 is supplied by a pipe 36 coming from a heat exchanger 33.
  • the latter receives the pipe 18 and a pipe 34 for supplying cold oxidant gas, for example cold air.
  • This cold air is heated in the exchanger 33 by the calories conveyed by the gases produced by the gasifier which, cooled, are evacuated through a pipe 19.
  • each injector 31 there opens an opening 32 which is supplied with gas by a recycling conduit 41 connected to the outlet 12.
  • the assembly 31-32 is arranged to provide one. good mixture between oxidizing gas and combustible recycled gases, as in a conventional gas burner.
  • a suction device 42 constituted by a refractory fan supporting high temperatures is disposed between a conduit 43 connected to the outlet 12 and the conduit 41.
  • the conduit 43 opens, at 43a, towards the rear of the gasifier, in a compartment 12b located under the grid 12a.
  • At least one burner 35 capable of being supplied with fuel, is disposed at the rear of the chamber 10.
  • the chamber 22 being loaded and the piston 21 being in the rear position, the advance movement of the latter is controlled as soon as the drying, pyrolysis and gasification operations have started.
  • the start-up phase of the operation of the gas generator having ended, which can be seen by observing the flow of gas produced, the burner 35 is switched off.
  • the hot gases are then produced by the reaction of the gases recycled through the pipe 41 with the air or the combustion oxygen injected at the front of the chamber 10.
  • the hot combustion gases are produced at the front of the chamber 10 in a free space contained in this chamber and located in front of the natural slope formed in front of the materials contained in the chamber 10.
  • the particles of materials closest to the opening 14 are attacked by the hottest gases (approximately 1200 ° C). The carbon possibly remaining at the heart of these particles is thus reached and the rejected ashes have been completely gasified.
  • the hot gases progress from front to rear through the materials to be treated under the effect of suction by the fan 42.
  • the arrangement of the outlets 12 and 13 in the floor of the chamber 10 requires combustion gases to cross the bed of materials to be treated over its thickness and practically throughout the room.
  • the temperature of the gases gradually decreases, and reaches approximately 800 ° C. at the level of the outlet 13.
  • the gases not captured by this outlet pass, towards the rear, the pyrolysis P and drying S zones. before being taken up in the recycling conduit by outlet 12.
  • the temperature of the recycled gases is at least 500 ° C, approximately 600 to 700 ° C.
  • the temperature of the gases is relatively high.
  • the time required for these operations is therefore short.
  • the length of the drying and pyrolysis zones is therefore quite short.
  • the outlet 13 is the outlet from which the gas produced by the gasifier is taken. To avoid the presence of tars in this gas, it is desirable that the outlet 13 is located in front of the pyrolysis zone or at the limit between the latter and the gasification zone. In practice, this means that the outlet 13 is located at a distance from the opening 14, at the front of the chamber 10, between approximately L / 4 and L / 2, L denoting the distance between the rear end of the chamber 10 and opening 14.
  • the outlets 12 and 13 are formed in the floor 11 of the chamber 10.
  • the hot gases passing through the materials contained in the chamber thus necessarily come into contact with the materials located in the bottom of the chamber 10, which could not be the case if the openings 12 and 13 were located at a certain height above the floor 1 a.
  • the advance of the materials into the chamber 10 is produced by the piston 21. It will be noted that the materials entering the chamber are brought straight away to a high temperature (several hundred ° C.). The carbonization of materials is very fast. The materials to be treated therefore very quickly become brittle, in particular in the vicinity of the wall 11 which prevents any jamming of these materials which may oppose the force exerted by the piston 21.
  • the advance of the piston 21 is interrupted when 'It reaches the front of the chamber 22, this interruption only during the time necessary to return the piston 21 to its rear position and fill the chamber 22. The advance movement of the piston 21 can then immediately resume.
  • the advance speed of the piston 21 is determined as a function of the treatment speed in the chamber.
  • This treatment speed is relatively high, in the present case, because the materials to be treated are subjected to high temperatures as soon as they enter the chamber 10.
  • the processing speed is not only a function of the temperature of the gases passing through the bed of materials to be treated, but also, and above all, a function of the flow rate of the recycled gases and, thereby, the flow rate of the gases passing through the chamber 10. , a strong recycling results in a strong gas flow in the gasification zone and, consequently, in a high reaction speed.
  • the adjustment of the flow rate of recycled gases can be carried out by adjusting the position of an adjustable flap inserted in the duct 43 or by modifying the speed of the suction fan 42.
