PCT No. PCT/SE87/00627 Sec. 371 Date Jun. 26, 1989 Sec. 102(e) Date Jun. 26, 1989 PCT Filed Dec. 22, 1987 PCT Pub. No. WO88/04953 PCT Pub. Date Jul. 14, 1988.A purification unit for separation of solid particles from gases comprises at least one group of a plurality of flow cylinders arranged in a common chamber. Each flow cylinder has a fixed rotary head for setting incoming gas in rotary motion, an outlet diffuser 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 this gap, separated particles stream out to the chamber. In order to obtain at least the same purifying effect with several dust separators connected in parallel and each including a flow cylinder with a fixed rotary head and outlet diffusor as with one single dust separator, the common dust collecting chamber is connected by way of at least one suction line to a steplessly adjustable blower in order to maintain a negative pressure in the chamber optimizing the purification. |
