<p>There is provided a process and a corresponding device for environmental control in industrial plants, particularly intended for use in the textile stain-removal sector, in which following dispersion of a polluting agent in an open internal environment of the industrial plant, an emitting device (6) is activated so as to cause discharge of an air mass taken from the internal environment into an environment external to the plant. Through an exhaust duct (7) incorporating filtering means (10), predetermined amounts of the polluting agent are removed bringing the exhausts to the outside within the prescribed standards. The device comprises means (11) for automatic control of filtering to evaluate the real operation of the emitting device (6); the control means (11) is able to deactivate the emitting device (6) either in case of absence of the polluting agent in the sucked air mass or in case of partial or full exhaustion of the filtering power of the filters (13). <IMAGE></p> |
