Embodiment Construction

[0020] The wet gas scrubber shown in the accompanying drawings is used to remove solid and / or liquid particulates from water-saturated gases at a consistently high cleaning efficiency. The adjustable Venturi effect cleaning area is formed by two horizontally arranged Venturi effect plates 5, 6, the relative distance between which the two Venturi effect plates are adjustable; this adjustable Venturi effect cleaning area ensures uniform A cleaning efficiency of , wherein a uniform gas velocity and thus a uniform pressure drop is obtained in the case of fluctuating gas volumes.

[0021] The adjustable Venturi effect area comprises a plurality of curved Venturi effect channels 9, 9' extending from the Radially inwardly extending radially outwardly.

[0022] The gas to be cleaned is introduced into the wet gas scrubber from above; the cleaning liquid is injected into the gas to be cleaned through the nozzle 7 before the gas to be cleaned reaches the Venturi effect area. The mixtu...

Abstract

This invention relates to a wet gas scrubber for removing solid and/or liquid particles from water-saturated gases with a Venturi zone adjustable with respect to the flow cross-section, comprising a plurality of Venturi channels (9, 9') through which a mixture of the gas to be cleaned and the cleaning liquid droplets injected into the gas stream through a nozzle (7) is guided. The Venturi channels (9, 9') are formed between two substantially parallel Venturi plates (5, 6) provided with segments (10) which engage in each other while the Venturi channels (9, 9') are kept free, wherein the Venturi channel cross-sections are synchronously adjustable by relative adjustment of the coaxial Venturi plates (5, 6) with respect to each other.

Description

technical field [0001] The present invention relates to a wet gas scrubber for the removal of solid and / or liquid particles from a gas with a Venturi effect zone adjustable with respect to the flow cross section, the Venturi effect zone comprising a plurality of Venturi effects A channel through which a mixture of the gas to be cleaned and the cleaning liquid droplets injected into the gas flow by means of nozzles is guided. Background technique [0002] Various types of wet gas scrubbers are known for removing solid and / or liquid particles from gases, including those utilizing the so-called Venturi effect. Here, the inlet air flow to be cleaned is used to break up the cleaning liquid into very fine droplets, which capture particulate and droplet-shaped impurities from the air flow to be cleaned and can thus be discharged. [0003] A simple Venturi effect gas scrubber has a central throat region of equal cross section, a cone narrowing in the flow direction adjoining the in...
