    Abstract: A gas cleaning unit for cleaning an effluent gas of at least one aluminium production electrolytic cell comprises a contact reactor in which the effluent gas is brought into contact with alumina, and a dust removal device for removing at least a portion of the alumina. The gas cleaning unit further comprises a wet scrubber in which the effluent gas is brought into contact with an absorption liquid containing water for removing further pollutants from the effluent gas. The wet scrubber is positioned at a point vertically higher than that of the dust removal device.

    Abstract translation: 用于清洁至少一个铝生产电解池的废气的气体清洁单元包括其中废气与氧化铝接触的接触反应器和用于除去至少一部分氧化铝的除尘装置。 气体净化单元还包括湿式洗涤器，其中废气与含有水的吸收液体接触，以从废气中除去进一步的污染物。 湿式洗涤器位于垂直于除尘装置的一点上。

    Abstract: A first contact reactor, mechanical separator device, one or more second contact reactors, silo, filter, one or more fans each equipped with one or more vibration dampers, an optional wet scrubber and stack are each integrated into a single compact air quality control system (AQCS) compartment. Additionally, a process gas cooling system may be integrated into the compact AQCS compartment. Benefits of the subject compact AQCS compartment includes footprint reduction, operating cost reduction from reduced pressure drop due to reduced ductwork, capital cost reduction from reduced ductwork, noise reduction, weather protection and increased adaptability to meet specific system requirements.

    Abstract: A wet scrubber for removal of at least one gaseous pollutant from an effluent gas includes an inlet opening. A gas distributor is arranged in a wet scrubber housing and comprises a diffuser having a cover plate. The cover plate is arranged in the path of the effluent gas flowing into the wet scrubber housing. The diffuser has at least one diffuser channel for transporting the effluent gas from the inlet opening into the wet scrubber housing.
