HYDROCYCLONE INSTALLATION
The invention relates to an installation for purifying a fibrous suspension, having multiple hydrocyclones (1) arranged adjacent to one another in a row, which hydrocyclones each have at least one feed connection (2), one accepted stock connection (3) and one reject material connection (4), and having at least one supply collecting line (5) which is connected to multiple feed connections (2) and which serves for the feed of the fibrous suspension, and/or having at least one accepted stock collecting line (6) which is connected to multiple accepted stock connections (3) and which serves for the drainage of the accepted stock, and/or having at least one reject material collecting line (7) which is connected to multiple reject material connections (4) and which serves for the discharge of the reject material, wherein the collecting line (5, 6, 7) is of elongate form and the corresponding connections (2, 3, 4) open at the longitudinal side thereof into the corresponding collecting line (5, 6, 7). It is the intention here for deposits in the collecting line (5, 6, 7) to be counteracted in that, at that end of at least one collecting line (5, 6, 7) which follows the final hydrocyclone (1), a fluid or a suspension is conducted at least via a flushing connection (8) into or out of the collecting line (5, 6, 7).
