Abstract
(EN)
Disclosed is a pyrolysis and gasification combined device of a circulating fluidized bed. The pyrolysis gasification combined device has an H shape in a bilaterally symmetrical arrangement with a boiler furnace (9) being the symmetrical line or the centre of symmetry. A side coal bunker (12) is connected to a pyrolysis and gasification furnace (1) and a back feed leg of a boiler back feeder (8) respectively. The boiler back feeder (8) is connected to the boiler furnace (9) via the back feed leg thereof. The side coal bunker (12) is arranged away from the boiler furnace (9). A cyclone separator (10) is arranged close to the boiler furnace (9). The pyrolysis and gasification furnace (1) is arranged between the side coal bunker (12) and the boiler furnace (9). A first stage separator (2), a second stage separator (3), a material returning device (5), a first stage material returning device (6) and a second stage material returning device (7) are arranged between the pyrolysis and gasification furnace (1) and the boiler furnace (9). The present pyrolysis and gasification combined device of a circulating fluidized bed employs a combined method where a H-shaped arrangement is added to the pyrolysis and gasification furnaces (1) arranged on both sides. Both the back feed leg of the boiler back feeder (8) and the pyrolysis and gasification furnace (1) of the circulating fluidized bed are combined to feed materials by arranging the side coal bunker (12), so that the connection devices between the boiler, the side coal bunker (12) and the pyrolysis and gasification furnace (1) are more simple and reliable.

L'invention concerne un dispositif combiné de pyrolyse et de gazéification d'un lit fluidisé à circulation. Le dispositif combiné de pyrolyse et de gazéification a la forme d'un H selon un agencement bilatéralement symétrique avec un foyer de chaudière (9) étant la ligne de symétrie ou le centre de symétrie. Une soute à charbon latérale (12) est reliée à un four de pyrolyse et de gazéification (1) et à un pied d'alimentation d'une alimentation de chaudière (8) respectivement. L'alimentation de chaudière (8) est reliée au foyer de chaudière (9) par l'intermédiaire du pied d'alimentation de ce dernier. La soute à charbon latérale (12) est agencée à l'opposé du foyer de chaudière (9). Un séparateur à cyclone (10) est disposé à proximité du foyer de chaudière (9). Le four de pyrolyse et de gazéification (1) est agencé entre la soute à charbon latérale (12) et le foyer de chaudière (9). Un séparateur de premier étage (2), un séparateur de second étage (3), un dispositif de retour de matériau (5), un dispositif de retour de matériau de premier étage (6) et un dispositif de retour de matériau de second étage (7) sont disposés entre le four de pyrolyse et de gazéification (1) et le foyer de chaudière (9). Le présent dispositif combiné de pyrolyse et de gazéification d'un lit fluidisé à circulation utilise un procédé combiné où un agencement en forme de H est ajouté aux fours de pyrolyse et de gazéification (1) disposés sur les deux côtés. À la fois le pied d'alimentation de l'alimentation de chaudière (8) et le four de pyrolyse et de gazéification (1) du lit fluidisé à circulation sont combinés pour fournir des matériaux en agençant la soute à charbon latérale (12), de sorte que les dispositifs de raccordement entre la chaudière, la soute à charbon latérale (12) et le four de pyrolyse et de gazéification (1) sont plus simples et plus fiables.
