Method and apparatus for scrubbing flue gas with flowable absorbing

Abstract

A method and apparatus for scrubbing flue gas that is charged with noxious material. Scrubbing is accomplished via flowable absorption material in a gas-scrubbing unit having an atomizing device with at least one independent nozzle in which, pursuant to the air flow atomization principle, the absorbing material, as atomizing material, is atomized in parallel flow with a gas, as an atomizing medium, to form a fine droplet stream while at the same time the atomizing material and the atomizing medium are intensely mixed. Atomizing material is introduced into a nozzle in such a way that the material forms a film on one side of an atomizer edge disposed in the nozzle. Each atomizing medium stream is split into two partial streams. One of these partial streams is passed through a given nozzle in such a way that it passes over the film of atomizing material in the direction toward the nozzle outlet, so that the film is forced toward the outlet, where it is atomized via the atomizer edge, as is passes thereover, to form a fine droplet stream. The other partial stream is passed through the nozzle on that side of the atomizer edge remote from the film of atomizing material, where it is mixed with the fine droplet stream.
