Abstract
Abstract Rotatable treatment chambers arranged on a drive shaft are bounded by disk-like boundary walls and radial partition walls. The treatment chambers are arranged in a spiral housing with tangential gas inlet and axial gas outlet. The gas to be treated enters the spiral housing tangentially on its outer periphery at a high velocity, it is sucked radially through the treatment chambers, and leaves the housing purified passing through a central gas outlet. Due to the rotation of the treatment chambers by which the gas is set in rotation, a gravity field is produced whose direction is opposite to the direction of flow of the gas. Accordingly, gases and vapors to be purified receive such a high centrifugal acceleration that the suspended particles they contain, due to their centrifugal acceleration, are separated out in the direction against the flow of the gases and vapors. This effect is enhanced by additional injection of fluid. This arrangement can also be used for the absorption of gas components.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
229 words
Apparatus for agglomerating and precipitating suspended matter out of gases and vapours and also for absorbing gas components in a wet process, comprising a housing having a pair of side walls joined by a curved wall providing a curvilinear periphery for said housing, a rotatable shaft extending into said housing through at least one of said side walls and being positioned centrally of said curved wall, an inlet connected to said housing for supplying gas into said housing at its curvilinear periphery, an outlet connected to said housing and disposed substantially concentrically about the axis of said shaft for removing gas centrally from said housing, and means positioned within said housing and secured to said shaft for rotation with said shaft, said means forming radially extending treatment chambers open at the radially outer and inner ends thereof, and closed at least partially on the lateral sides of the treatment chambers between the radially outer and inner ends, whereby said shaft is rotated at a higher rate of speed and the gas is supplied so that it flows radially inwardly from said inlet through the treatment chambers to said outlet flowing counter to the field of gravity generated by the rotation of said shaft and said means secured to said shaft so that suspended particles are removed from the gas and moved in the direction of the field of gravity.
