Abstract
Method and apparatus for wet-cleaning crude gas streams, the method involving a flow of the crude gas stream without a pressure drop or with a low pressure drop up to 30 mbar, preferably up to 20 mbar, flowing through one or more parallel venturi throats which is/are sprayed with a scrubbing liquid via one or more periodically pulsating hybrid nozzles.
Claims12
A method for cleaning a crude gas stream with the aid of an atomized scrubbing liquid, comprising the following steps:
- a) spraying a crude gas stream with an atomized scrubbing liquid, by means of at least one hybrid nozzle which operates to eject the atomized scrubbing liquid in alternating pulses of relatively coarse and relatively fine droplets, and then b) passing the resulting stream of gas plus atomized scrubbing liquid, without a pressure drop or with a low pressure drop, through at least one venturi throat.
Apparatus for cleaning crude gas with the aid of an atomized scrubbing liquid, comprising a flow tube, one or more venturi throats located in said flow tube, and at least one hybrid nozzle which operates to eject the atomized scrubbing liquid in alternating pulses of relatively coarse and relatively fine droplets, disposed within said flow tube upstream of said venturi throats.
