Abstract
An apparatus and method for wet cleaning a gas stream has a housing with a gas inlet and a gas outlet, wherein, in the housing, there is at least a first washing segment that serves to clean the gas stream with a washing liquid and that is arranged in the flow path of the gas stream. Inside the housing of the apparatus, there is at least one fan that regulates air pressure along the flow path of the gas stream. A bypass channel for bypassing the flow path through the at least one washing segment as well as a regulator that is arranged in the bypass and that serves to discharge the gas stream being conveyed via the bypass channel are arranged inside the housing.
Claims20
A device (10) for wet cleaning a gas stream, comprising:
- a housing (1) with a gas inlet (2) and a gas outlet (3);
- at least one washing segment (4) inside the housing (1) configured to clean the gas stream with a washing liquid, said first washing segment (4) being arranged in a flow path (15) of the gas stream;
- at least one fan (6) inside the housing (1) configured to regulate air pressure along the flow path (15) of the gas stream;
- and
- a bypass channel (7) inside the housing (1) for bypassing the flow path (15) through the at least one washing segment (4) and a regulator (8), with said regulator (8) being arranged in the bypass channel (7) and configured to discharge the gas stream being conveyed via the bypass channel (7).
A method for wet cleaning a gas stream, comprising:
- (i) feeding the gas stream that is to be cleaned into a device (10) for wet cleaning gases, said device (10) having a housing (1) with a gas inlet (2) and a gas outlet (3), at least two washing segments (4), (5) inside the housing (1) configured to clean the gas stream with a washing liquid, said first and second washing segments (4), (5) being arranged in a flow path (15) of the gas stream, at least one fan (6) inside the housing (1) configured to regulate air pressure along the flow path (15) of the gas stream, and a bypass channel (7) inside the housing (1) for bypassing the flow path (15) through the at least two washing segments (4), (5) and a regulator (8), with said regulator (8) being arranged in the bypass channel (7) and configured to discharge the gas stream being conveyed via the bypass channel (7),
- (ii) selectively switching the gas stream flow path to cause the gas stream to flow either (a) through at least the first washing segment (4) and the second washing segment (5), to clean the gas stream with at least one aqueous washing liquid, or (b) through the bypass channel (7) for bypassing the flow path (15) through the washing segments (4, 5) and in a flow path (16) through the bypass channel (7).
An apparatus for wet cleaning a gas stream, comprising:
- a housing with a gas inlet and at least two gas outlets and defining a first flow path of the gas stream and a second flow path of the gas stream;
- at least one washing segment in the housing adapted to clean the gas stream with a washing liquid, said first washing segment being arranged in the first flow path of the gas stream;
- at least one fan inside the housing adapted to regulate air pressure along the first flow path of the gas stream;
- a bypass channel in the housing defining the second flow path, said second flow path bypassing the first flow path through the at least one washing segment;
- and
- a regulator installed in the bypass channel and adapted to discharge the gas stream being conveyed via the bypass channel.
