ABSTRACT:
A bioscrubber for purifying dirty gas has a circulated scrubbing liquid which contains water and microorganisms for degradation of the substances to be separated off from the dirty gas. The gas enters at an inlet, moves through a mass-transfer zone, where it undergoes a phase change from the gas phase to the liquid phase, and the clean gas exits through an outlet. The system has a device for irrigating the mass-transfer zone with the scrubbing liquid, and a tank for collecting the scrubbing liquid and for activating the microorganisms. The bioscrubber has particularly high separation rates and particularly low risk of blockage because, in at least one mass-transfer zone of the bioscrubber, there may be provided a package of adjacent vertical tubes and a cleaning device for cleaning the tubes. A mass-transfer zone can be formed by a spray tower.
