  • the biomass should be required as a homogeneous substance or as broad a mixture as possible with a screw conveyor against overpressure.
  • the screw conveyor is designed so that at its end a Abdichtzone is arranged, whose feature is the absence of Forder instituten.
  • the length of the sealing zone should be greater than the diameter of the screw tube or as the gap between the screw shaft and screw tube so that a dynamic pressure is generated by the wall friction and can close, which originated behind the screw spiral cavities.
  • this sealing zone may have a cross-sectional constriction, which compresses the biomass by an increased resistance.
  • the Cross-sectional constriction must take into account the stubbornness of the biomass.
  • the cross-sectional constriction can be made by an adjustable counter-pressure device.
  • the counter-pressure device can be formed from a displaceable mandrel whose tip can also be rounded.
  • the counter-pressure device can be formed by a conically narrowed Rohrstuck.
  • a conically narrowed Rohrstuck is described in EP 1 586 439 A1 for a screw press, without this device being suitable for demanding against a pressure gradient, nor is there any suggestion for guidance for the method according to the invention.

  • the end of the screw press must be designed as a sealing zone according to claim 1, which does not contain a spiral screw.
  • the sealing zone may also have a temporary cross-sectional widening.
  • larger biomass parts of smaller biomass parts can be enclosed in such a way that results in a total of a pressure-tight plug.

  • For maintenance is the
  • a shut-off valve 12 between screw conveyor and pressure vessel 11 appropriate. Since a plug of solid biomass is not completely gas-tight, the arrangement of a suction 13 at the feed hopper 9 is appropriate.
  • the suction expediently contains a measuring device for the Volume flow and a detector for a coming from the pressure vessel 11 gas. Based on these data, one can change the properties of the incoming biomass in a targeted manner. The density of the plug can be changed by mixing different biomass, by heating and changing the mashing with a liquid. In the event that the biomass 7 is to be supplied to a reactor for the production of synthesis gas, the water content of the biomass should remain as low as 60% by Anmaischen so that the efficiency of the gasification does not decrease too much.

Abstract

A=Il est difficile d’amener une matière solide hétérogène, telle que de la biomasse, dans un récipient sous pression. Les sas à roue cellulaire et les sas à pression utilisés jusqu’à maintenant présentent des inconvénients importants. L’utilisation de convoyeurs à vis conventionnels s’est heurtée jusqu’à maintenant au fait qu’un canal de gaz se forme derrière la spirale de la vis sans fin, ce canal entraînant une perte de pression dans le récipient sous pression. Ces problèmes sont résolus grâce à l’utilisation d’un convoyeur à vis (3) dont le tube (1) présente une zone d’étanchéité (2) qui ne comporte aucun organe de convoyage. La présente invention est adaptée à l’amenée de biomasse dans une installation de gazéification sous pression pour la fabrication de gaz de synthèse.
