ABSTRACT:
The present invention relates to a gas separation apparatus, a front wall and a separation rotor thereof. The invention especially relates to the modification of the separation rotor and/or the front wall of the gas separation apparatus in such a way that liquid or liquid suspension separated from a mixture containing gas and liquid or liquid suspension by means of said separation rotor may be recirculated as simply as possible back to the process flow at the same time as the gas separated from said liquid or liquid suspension is guided out of the process.A characteristic feature of the gas separation apparatus comprising a front wall (50) and a separation chamber (62) arranged in communication with said front wall (50), a disc (60) mounted on the shaft (42) and located within said separation chamber, said disc dividing the separation chamber (62) to a so called front chamber (64), and a so called rear chamber (66), vanes (68) arranged to said disc (60), and at least one opening (70) for allowing gas-containing liquid or gas to enter the rear chamber (66) on the rear side of the disc (60), is that the front wall (50) surface facing the front chamber (64) is at least partially provided with ribs (74), by means of which the rotation of the liquid in the separation chamber (62) is prevented in the front chamber (64).
