Definitions
- the present invention relates to a co-current gasifier as described in the prologue of claim 1.
- co-current gasifiers of which the most efficient are the gasifiers at a hearth, also called combustion chamber, of form circular obtained by a narrowing of the fuel supply chamber, in which the fuel moves from top to bottom by gravity (this is, for the accuracy of the gasifiers mounted on vehicles during the forties and supplied with wood, type IMBERT) then made it possible to verify a principle of great importance, i.e. co-current gasification ensures the production of a gas in which tar, dioxins and furans are absent, only at the provided that a certain ratio between the surface of the hearth and the average particle size fuel is respected.
- the dimensions of the hearth must be adapted to the grain size. average fuel to be gasified. Materials of small particle size, such as for example plant residues, household or industrial, prepared for the gasification, (dried, shredded, homogenized to obtain a fuel whose properties are regular) therefore require, according to the aforementioned condition, that the fireplace dimensions are also limited, thereby limiting the power of such gasifiers.
- the present invention proposes to eliminate these drawbacks of the technology of known co-current gasifiers, so as to be able to produce gasifiers of medium and high power (of the order of at least 1 MWel) which guarantee the production of a gas without tars, dioxins and furans, in quantity and in quality, respectively constant regarding these perfect parameters, and to create among other the ideal conditions for the use of syngas for energy production electric supplied by internal combustion engines.
- Another object of the invention is to prepare the ideal conditions for manufacturing co-current gasifiers of variable power, as required, by providing element modules which can be mechanically coupled and / or activated as required.
- the pos. 1 of the same fig. represents a worm for feeding material fresh. It transports the material coming from a feed hopper (better visible in fig. 3) to bring it to the start of the turns of a vertical worm 2 which transports this material from the bottom to the top.
- the worm 2 is well heard in a cylindrical housing 3, possibly provided with all the elements known to each person skilled in the art, elements intended to promote correct transport material from bottom to top.
- the rotation shaft 4 of the screw 2 can be hollow, as shown in fig. 1, for a reason which will be explained further.
- the shaft 4 of the screw 2 is driven by a gear 5 and a helical gear 6.
- the material supply screw 1, the cylindrical housing 3, the vertical shaft 4 of the vertical screw 2, as well as the gears 5 and 6 are supported, respectively fixed, in, respectively, a frame 7, with the necessary housings, which can be equipped, as in the case rotating shafts, linear or rotary ball bearings.
- a hearth is created, according to the invention, understood by that, that in this zone, in the shape of a full disc, all the material which cross member is forced to pass into a combustion zone, where it is brought to the temperature of at least 1200 ° C for a sufficient time.
- a hearth is created, according to the invention, understood by that, that in this zone, in the shape of a full disc, all the material which cross member is forced to pass into a combustion zone, where it is brought to the temperature of at least 1200 ° C for a sufficient time.
- outside air is supplied by means of a fan (not indicated) and a tube supply 8, to a circular chamber 9 surrounding the upper edge of the housing 2 at a point above the highest point of the turns of the vertical screw 2, where the material transported to gasify forms a compact column.
- the diameter of the screw vertical 2 does not exceed a certain dimension, mainly depending on the average particle size of the material to be gasified and preferably situated for a optimal functioning of the gasifier according to the present invention and for the combustion of wood chips of approximate dimensions of cm, from 100 to 200 mm and more, the supply of air only from the outside may be sufficient to ensure the necessary and regular combustion over the entire surface of the fireplace.
- a primary combustion air supply to the lower part of the hearth i.e. at the lower central part of the disc which forms the hearth: to achieve this variant of the combustion air supply, it it will suffice to provide that the shaft 4 of the vertical screw is, as already shown in FIG. 1, a hollow shaft supplied from below, by means of the supply tube 10, with air which passes through the shaft on which the gear 5 is fixed, a shaft which is therefore hollow.
- the combustion air supply conditions in the hearths are particularly difficult (due for example to a particle size relatively small material to be gasified compared to the diameter of the hearth, respectively of the vertical screw 2, or at a higher flow rate of the material to gasify etc, ...) it may be useful, and may be necessary, to provide air oxidizer both from the outside of the hearth and from its bottom, i.e. its outer edge, ie at its lower central surface via the tubes 8 and 10. It is important that the material passes through the hearth, as a compact column which will be heated throughout its mass to a temperature above 1200 ° C for enough time.
- a gasification chamber 11 disposed at the above the hearth, the function of which is described in detail in document EP-0565935 and that a device 12 for circulation of the material which has already passed through is provided the hearth and the gasification chamber 11.
- a circulation device 12 which can assume various forms and which will be described in more detail, in its constructive part and of operation, in a preferred embodiment, when the variants shown in fig. from 2 to 5, embodiment which allows to carry over gasifying material in fresh material which has not yet been carbonated, another time through the foyer.
- Figures 2, 3 and 4 show precisely the possibility of coupling four gas generators and, on this subject, it should be mentioned that two gasifiers put together, one against the other, as can be seen in the section of fig. 2, constitute a module of ideal base for the combination of such multiple gasifiers.
- the right part of fig. 2 is perfectly equal and opposite to that on the right.
- the elements shown in fig. 2 are therefore exactly the same as those described in fig. 1 and are no longer described separately.
- the advantage of combining two gas generators coupled to form a ideal basic module is that the material feed auger 1 and the helical gear 6 of the supply of the vertical screws 2 and 2 ', both horizontal and parallel to each other, can be used optimally to power the two coupled gasifiers, which considerably simplifies the construction of the device.
- the screw rotation device 2 and 2 ′ comprises, in the variant of FIG.
- the feed screw 1 for fresh material - analogously as described for the shaft helical gears 6 - is arranged in the vertical plane of symmetry of each ideal basic module of two coupled gasifiers and that it even extends along the entire length of the gasifier, feeding collectively all the gas generators constituting the said device.
- Figs. 1 to 4 we see a particularly preferred form of the circulation 12, 12 'of the material which has already passed through the foyer and the gasification 11, 11 '.
- a device comprises a horizontal worm discharge 19, 19 'for each gasifier, arranged above the gasification 11, 11 ', respectively between the gasification chambers 11, 11' and the expansion chamber 14.
- the worm 19,19 'evacuation of each gasifier, including the axis is perpendicular to that of the feed screw 1, pushes the pyrolyzed material (coal) and / or not yet completely gasified outside of the gasification 11, 11 'of the gasifier and returns it to the zone where the screw is located endless 2 or 2 '. In this way the material to be circulated is mixed with the fresh material fed by feed screw 1 and passes through a hearth of another gasifier.
- fig. 2 is shown an additional detail, concerning the module formed by the coupling of two gasifiers, which shows how the air primary oxidizer which passes through the tube 10 can be preheated, and cool the said screw before entering the trees 4, 4 ′ of the so-called gas generators.
- the air is pulsed by a fan (not shown) through the tube 20 on which the screws are fixed endless 19, 19 'evacuation of the two gasifiers making up the ideal basic module. Passing through the tube 20 the combustion air is heated by conduction by the gas which goes up to the expansion chamber 14 and licks the tube 20.
- the horizontal endless discharge screws 19, 19 ′ of the two coupled gas generators, making up an ideal basic module move the material in circulation as shown in figs. 2 and 3.
- the screws endless horizontal evacuation19, 19 'of the two coupled gasifiers forming a ideal basic module when they rotate in the normal direction, move the material circulation, towards the center of the module, in a vertical channel, through which the circulating material descends on the fresh material feed screw 1.
- Fig. 5 shows a later variant of two gasifiers coupled to form a ideal basic module, the advantage of which is to reduce the bulk, especially in the lower part of the gasifier.
- the axes of the two screws 25,26 two gasifiers coupled to form an ideal basic module form between them an angle ⁇ between 0 and 20 °.
- the vertical screws 2, 2 ' are defined as "essentially" vertical, but a slight tilt does cannot be excluded from the scope of the invention.
- the gasifier according to the invention also offers the advantage when it is combined with other gasifiers to form a higher power gasifier, if the essentially vertical screws 2, 2 'etc are to be actuated individually, it is possible, in a device composed of several gasifiers, to maintain in function only those who are really useful at each moment, to adapt the apparatus for the energy productions actually necessary, respectively for the availability of equipment to carbonate. For this purpose, it is sufficient to provide that, in a solution like the one shown in figs. 2 to 4, gears 5, 5 'etc, screws 2, 2 'etc, either connected with the respective shafts by a coupling mechanical or any other system, which allows them to be released when you want to stop the operation of the corresponding gasifier. Another possibility, shown in embodiment of fig.

Abstract
L'avantage de cette forme de réalisation, comparée à l'Etat de la Technique qui prévoit l'utilisation d'un foyer annulaire, réside dans le fait qu'elle élimine le risque de formation de passages préférentiels et de canaux dans la zone de gazéification qui provoquent des irrégularités de combustion et de gazéification, et qu'elle adapte l'épaisseur de la zone de combustion à la granulométrie moyenne du matériel. En outre le gazogène selon la présente invention se prête à l'assemblage de deux gazogènes, pour former ainsi des appareils de gazéification de puissances élevées (5 kWél. et plus) dotés cependant de grandes variations d'utilisation et d'adaptation optimale, grâce à la possibilité de faire fonctionner séparément les gazogènes individuels, adaptant ainsi la production d'énergie à la disponibilité momentanée du combustible.
