Abstract

Le procédé se caractérise en ce qu'un matériau gazéifiable est alimenté au moyen d'un dispositif hélicoïdal (3) vers un tambour (1) pourvu d'écrans à lèvre (2) et monté dans une enceinte à double coquille (7), le matériau dans le tambour étant déplacé longitudinalement vers une partie de décharge de gaz (4), où le matériau incombustible est déchargé au travers d'une ouverture de descente (5) dans un dispositif hélicoïdal (13) et ensuite au travers d'un canal (14), tandis que l'air à l'arrivée est guidé au moyen des écrans à lèvre vers le fond du tambour dans une direction opposée à la direction de rotation du tambour, afin d'entretenir le flottement du matériau sur le fond. L'espace intermédiaire (7) de l'enceinte refroidit la coquille intérieure et réchauffe l'air primaire (8) admis sous le tambour et aspiré ou circulant de force au travers du tambour, tandis qu'une chambre d'air (9) permet d'assurer la vitesse correcte de l'air d'admission. Le matériau introduit dans le tambour est sous forme compacte et les gaz de fumée s'écoulent au travers d'un assemblage de filtre vibrant (12) contenant généralement de la pierre à chaux et sont ensuite déchargés au travers d'une ouverture (15). Le matériau gazéifiable peut être composé de rebus, de tourbes ou d'un matériau analogue.The method is characterized in that a gasifiable material is fed by means of a helical device (3) to a drum (1) provided with lip screens (2) and mounted in a double shell enclosure (7), the material in the drum being moved longitudinally to a gas discharge portion (4), where the non-combustible material is discharged through a descent opening (5) in a helical device (13) and then through a channel (14), while the incoming air is guided by means of the lip screens towards the bottom of the drum in a direction opposite to the direction of rotation of the drum, in order to maintain the floating of the material on the bottom . The intermediate space (7) of the enclosure cools the interior shell and heats the primary air (8) admitted under the drum and sucked in or circulating by force through the drum, while an air chamber (9) ensures the correct speed of the intake air. The material introduced into the drum is in compact form and the flue gases flow through a vibrating filter assembly (12) generally containing limestone and are then discharged through an opening (15) . The gasifiable material may be composed of scrap, peat or the like.

Description

Method for the production of combustible gas and device for applying the method
This invention concerns a method for the production of com bustible gas and a device for applying the method.
Various types of. devices for the production of combustible gas are already known, although none of these have the same uniform feed and heat as the device according to the inven tion, due to the rotation of the drum and the material being in a floating state.
The method and the device according to the invention are characterised by the attached patent claims.
The invention will now be described in more detail, with reference. to the attached drawing, in which Figure 1 shows the device viewed from the side and. Figure 2 is a cross- section through Figure 1.
Figures 1 and 2 show a device consisting of a rotatable drum 1, provided with holes, known as lip screens 2, along its periphery, the lip screens being of variable size. The lip screens 2 operate in such a manner that the incoming air is guided to the bottom of the drum, in a direction opposite to the direction of rotation of the drum, and the air thus keeps the material floating along the bottom and increases the combustion rate. liefuse, peat and similar materials caoable of being gasified are fed by means of a spiral 3 into the drum 1. The material is displaced longitudinally by the drum by means of guide elements towards the gas discharge part 4, where incombustible material is also diεcharced through a hatch 5 down onto a screw 13. The drum is located in a twin shell casing 6. The intermediate space 7, the top of which is fitted with a guide plate designed to force the flue gas towards the bottom 1 of the drum, serves for cooling the inner shell and simultaneously heating the primary air 8, which is drawn in under the drum and is forced or drawn in the drum, whereby the air chamber 9 is sized so that the correct velocity of the incoming air will be obtained. The outer shell 10 is insulated in a suitable manner.
The drum is supported in a suitable manner - either by means of a horizontal shaft 11 or by means of a vertical suspension on the discharge side, in the casing 6. In both cases, the drum supports are air-cooled. The feed end of the drum 1 also serves as suspension. The feed material is compact on its entry into the drum 1, i.e. it prevents air being admitted this way. The flue gases formed pass through a filter assembly containing, for instance, limestone and equipped with a vibrator device, and the flue gases are discharged through the opening 15. The incombustible material is removed from the casing in a two-stage procedure (hatch 5, screw 13 - sluice 14). The device is also equipped with an apparatus for igniting the material (on starting) a is also controlled by microcomputers (not shown).
The invention is naturally not confined to this particular design, but can obviously be varied v/ithin the framework of the idea behind the invention.
