Title (EN) SYSTEM AND METHOD TO CONTROL PRESS SECTION DEWATERING ON PAPER AND PULP DRYING MACHINES USING CHEMICAL DEWATERING AGENTS
(FR) SYSTEME ET PROCEDE PERMETTANT DE COMMANDER L'ESSORAGE DE LA SECTION DES PRESSES SUR DES APPAREILS DE SECHAGE DE PAPIER ET DE PATES A L'AIDE D'AGENTS D'ESSORAGE CHIMIQUES
Abstract: front page image
(EN)The present invention provides an automatic control system, method and paper manufacturing machine using such control system for automatically controlling the amount of press section dewatering via the metered application of chemical dewatering agents applied to a paper web in a paper manufacturing process. The control system includes a feedback controller for controlling the amount of chemical dewatering agent applied to a paper web, and a monitoring device for obtaining a measurement of the moisture of the paper web exiting the press section.
(FR)La présente invention se rapporte à un système de commande automatique, à un procédé et à un appareil de fabrication de papier faisant appel à un tel système de commande, afin de commander automatiquement le degré d'essorage de la section des presses par l'intermédiaire de l'application dosée d'agents d'essorage chimiques sur une bande de papier au cours d'un processus de fabrication de papier. Le système de commande selon l'invention comprend un contrôleur de rétroaction destiné à réguler la dose d'agent d'essorage chimique appliqué sur une bande de papier, et un dispositif de contrôle permettant d'obtenir une mesure de la teneur en humidité de la bande de papier sortant de la section des presses.
