Title (EN) METHOD AND DEVICE FOR CONTROLLING INLET VALVES OF A COMPRESSIONTYPE CHEMICAL REACTOR
(FR) PROCEDE ET DISPOSITIF DES SOUPAPES D"ADMISSION D"UN REACTEUR CHIMIQUE DU TYPE A COMPRESSION
Abstract: front page image
(EN)A method of controlling the inlet valves of a compression-type chemical reactor consists in continuously measuring, during the operation of the reactor (1), the pressure inside its working chambers (4, 5) and supply lines (7, 6) and in determining the sign of the pressure differential ((Alpha)P) between the said working chambers (4, 5) and the corresponding supply lines (7, 6). Upon change of sign of the pressure differential ((Alpha)P) from "minus" to "plus" a signal is formed for relieving the inlet valves (8, 9) from any controlling influence with the exception of the pressure differential, whereas upon change of sign of the pressure differential ((Alpha)P) from "plus" to "minus" a signal is sent for the start of counting a time interval (u), after the expiration of which a signal is formed for closing the inlet valves (8, 9) of the chemical reactor (1). A device for controlling the inlet valves of the compression-type chemical reactor comprises drives (10, 11) for the inlet valves (8, 9) of the chemical reactor (1), pressure sensors (14, 15, 16, 17) mounted inside the working chambers (4, 5) and supply lines (6, 7), comparators (18, 19) connected to the outputs of the sensors (14, 15, 16, 17), units (12, 13) for controlling the drives (10, 11), the inputs of those units being connected, through timers (20, 21), to the outputs of the comparators (18, 19) and their outputs to the drives (10, 11), and a chronometer (22) connected to one of the comparators (18, 19).
(FR)Procede de commande des soupapes d"admission d"un reacteur chimique du type a compression consistant a mesurer continuellement, pendant le fonctionnement du reacteur (1), la pression a l"interieur de ces chambres de travail (4, 5) et de ces conduites d"alimentation (7, 6) et a determiner le signe de la pression differentielle ((Alpha)P) entre les chambres de travail (4, 5) et les conduites d"alimentation correspondantes (7, 6). Lors d"un changement de signe de la pression differentielle ((Alpha)P) du "moins" au "plus", un signal est forme pour liberer les soupapes d"admission (8 9) de toute influence de commande a l"exception de la pression differentielle, tandis que lors d"un changement de signe de la pression differentielle ((Alpha)P) du "plus" au "moins", un signal est envoye pour commencer a compter un intervalle de temps (u, apres expiration duquel un signal est forme pour fermer les soupapes d"admission (8, 9) du reacteur chimique (1). Un dispositif de commande des soupapes d"admission du reacteur chimique du type a compression comprend des dispositifs d"entrainement (10, 11) pour les soupapes d"admission (8, 9) du reacteur chimique (1), des detecteurs de pression (14, 15, 16, 17) montes a l"interieur des chambres de travail (4, 5) et des conduites d"alimentation (6, 7), des comparateurs (18, 19) connectes aux sorties des detecteurs (14, 15, 16, 17), des unites (12, 13) de commande des dispositifs d"entrainement (10, 11), les entrees de ces unites etant connectees, par l"intermediaire de minuteurs (20, 21), aux sorties des comparateurs (18, 19) et leurs sorties aux dispositifs d"entrainement (10, 11), et un chronometre (22) connecte a l"un des comparateurs (18, 19).
