A waste gases-neutralizing device comprises a filter installation with at least one filter unit (11, 12, 13) with an inlet (2) and an outlet (3) between which a filter (5) is received to remove undesired components form the waste gases. The installation has a modular construction and comprises a number of filter units which are placed in series in a flow path of the waste gases and/or a reactor vessel provided with a nozzle (50) with mixing chamber in which waste gases are at least partially removed with a mixture of at least one neutralizing compound and oxygen under pressure. The filter units each comprise a filter adapted to a specific component or group of components to be removed from the waste gases. The waste gases-neutralizing device preferably also comprises, in addition to the filter installation, a neutralizing unit 21 comprising a neutralizing liquid bath or a fixed connection impregnated with a neutralizing liquid. The waste gases-neutralizing device preferably also comprises a UV generator.
Waste gases-neutralizing device comprising a filter installation with at least one filter unit with an inlet and an outlet between which a filter is received to remove undesired components to at least a significant extent from the waste gases, characterized in that the installation has a modular construction and comprises a number of filter units which are placed in series in a flow path of the waste gases, and that the filter units each comprise a filter adapted to a specific component or group of components to be removed from the waste gases.
Waste gases-neutralizing device as claimed in one or more of the foregoing claims, characterized in that the filter unit has an at least substantially rectangular cross-section, that the inlet and outlet are placed diametrically opposite each other and that the outlet fits at least practically gas-tightly into the inlet.
Waste gases-neutralizing device as claimed in one or more of the foregoing claims, characterized in that after a final filter unit there is placed a neutralizing unit with a neutralizing liquid bath or a fixed connection impregnated with a neutralizing liquid which is able to make contact with the waste gases in order to remove to at least a significant extent from the waste gases reaction products of a filter unit possibly present therein.
Waste gases-neutralizing device comprising a reactor vessel provided with a nozzle with mixing chamber with which waste gases are at least partially removed with at least one neutralizing compound and oxygen, preferably in air.
