In order to provide a method of introducing auxiliary material into the flow path of a crude gas stream (120) charged with wet-paint overspray before the crude gas stream (120) passes through at least one filter element (172) for separating the overspray from the crude gas stream (120), with which method an introduction of auxiliary material into the application region (108) of a paint shop is reliably prevented even in the event of incorrect operation, a method is proposed, which comprises the following method steps: detecting whether there is an adequate crude gas flow through the at least one filter element (172); and blocking the introduction of auxiliary material into the flow path of the crude gas stream (120) if it is determined that there is not an adequate crude gas flow.
L'invention concerne un procédé d'introduction de matériau auxiliaire dans la trajectoire d'écoulement d'un flux de gaz brut (120) chargé de surpulvérisation de vernis humide, avant que le flux de gaz brut (120) ne passe au moins un élément de filtrage (172) destiné à séparer la surpulvérisation du flux de gaz brut (120). L'invention vise à mettre en oeuvre un tel procédé permettant d'éviter efficacement une introduction de matériau auxiliaire (108) dans un dispositif de peinture, même en cas de fonctionnement défectueux. A cet effet, le procédé consiste à déterminer si un flux de gaz brut suffisant est présent à travers le ou les éléments de filtrage (172), et à bloquer l'introduction de matériau auxiliaire dans la trajectoire d'écoulement du flux de gaz brut (120) s'il est déterminé que le flux de gaz brut est insuffisant.
