Patent ID: 7758819

Claim:
A waste gases-neutralizing device comprising: a filter installation with an inlet and an outlet between which a filter is received to remove undesired components from waste gases, said filter installation having a modular construction comprising a number of filter units placed in series in a flow path of the waste gases, wherein: each said filter unit is adapted to remove a specific undesired component or group of components from the waste gases, each said filter unit comprises a bath of a waste gas-neutralizing liquid that is adapted to interact with the waste gases and remove said undesired component or group of components, each said filter units comprises a system of mutually offset baffles extending traversely to said liquid bath to prolong the flow path of said waste gases along said liquid bath, said baffles are manually displaceable in an axial direction of said flow path, at least one upright inner wall of each said filter unit is covered with a porous layer extending from within said liquid bath, and a reactor vessel provided with a nozzle with a mixing chamber with which waste gases are at least partially removed with at least one neutralizing compound and oxygen.
