Abstract
Abstract A self-contained apparatus for the purification of gases which comprises a gas column in communication with a scrubbing chamber to permit the passage of gas from the column to the chamber. Turbine means is mounted for rotation in the gas column and is also connected to liquid pumping means. The movement of the gases through the column drives the turbine means which, in turn, activates the liquid pumping means so as to pump liquid from a reservoir into the scrubbing chamber. The action of the liquid on the gases in the chamber serves to remove the foreign matter entrained therein. The scrubbed gases are then released to the atmosphere via a gas discharge outlet.
