Purification unit for separation of solid particles from gases comprising at least one group of a number of flow cylinders arranged in a common chamber and each having a fixed rotary head for setting incoming gas in rotary motion, an outlet diffusor for purified gas projecting concentrically into the outlet end of each flow cylinder and forming together with the surrounding cylinder an annular gap with its inlet portion, through which gap separated particles stream out to said chamber. In order to obtain at least the same purifying effect with several dust separators connected in parallel and each comprising a flow cylinder with a fixed rotary head and outlet diffusor as with one single dust separator the common dust collecting chamber (8) is connected by way of at least one suction line (19) to a steplessly adjustable blower (18) in order to maintain a negative pressure in said chamber (8) optimizing the purification. |
