Venturi scrubber
ANA-Verfahrenstechnik
Gas scrubbers operate like jet pumps. They are designed in a way, that at low pressure differences the gas to treat is mixed with the scrubbing liquid turbulently and then it separates from it.
The liquid driving medium is transformed to subtle drops by a driving nozzle axially in a vertical pipe. The drops transmit their impulse to the gas stream that is sucked by the created drain and gets compressed. The reached gain of pressure is sufficed to compensate the pressure drop in a following packing material column. Because of the pressure gain mechanical ventilators need not be used for sucking and hauling the gases. The drops of the driving liquid also scrub the gaseous parts. Between the drops and the gas phase there is an intensive exchange of matter, so during the hauling there is also gas scrubbing.
After the gas scrubbing plant there is a separator vessel. It is for separation the mixture of scrubbing liquid and the gas on one hand, and on the other hand as liquid tank for scrubbing liquid, that is hauled by a recirculation pump in a circulation.
