Abstract (en)
The present invention concerns an improved mixing system (10) for the introduction of chemical substances in a fluid to be treated, comprising: a container (11) comprising an external wall (12), an internal wall (13), a bottom (14) and a cover (15); at least two concentric mixing chambers in communication with each other, a first central chamber (16) defined within the internal wall (13) and a second chamber (17) defined outside the internal wall (13); an inlet duct (19) for a fluid to be treated, configured for the introduction of the fluid in the cone (14); an outlet duct (20) for the treated fluid, configured for the outflow of the fluid from the second chamber (17) to the outside of the container (11); the inlet duct (19), the first chamber (16), the second chamber (17) and the outlet duct (20) defining a labyrinthine mixing path (30); stirring blades (18) positioned inside the first chamber (16); at least one injection passage (22), characterized in that the bottom has the form of a cone (14) extending from the external wall (12), said cone (14) being extended by a tube (23) whose the end forms the inlet duct (19) for the fluid to be treated , the cone (14) has an internal angle alpha comprised between 10° and 60°, and the at least one injection passage (22) is positioned on the cone (14), or on the tube extending from the cone (14),
