SYSTÈME DE COMMANDE DE CHUTE DE PRESSION ET PROCÉDÉ DE COMMANDE DE DISTRIBUTEUR D'ALIMENTATION D'UN RÉACTEUR À LIT FLUIDISÉ

摘要

Disclosed are a pressure drop control system and a control method for a feed distributor (10) of a fluidized bed reactor (100). The system includes: a measuring unit (5) configured to measure a pressure drop between a first pressure measurement port (2) and a second pressure measurement port (3) of the feed distributor (10), the first pressure measurement port (2) being located in an inlet tube of the feed distributor (10) near a reactor wall (4) of the fluidized bed reactor, and the second pressure measurement port (3) being located in an area of the reactor wall (4) between an air distribution plate (6) of the fluidized bed reactor (100) and a gas outlet of a nozzle of the feed distributor (10); a transfer unit configured to carry on signal communications with the measuring unit (5) and collect a signal about the pressure drop; and a processing unit configured to determine whether the feed distributor (10) is working normally or not based on the signal about the pressure drop.
