Problems solved by technology

[0021] Regardless of the known static mixers, the high pressure losses generated by the mixing and / or transfer elements have always constituted a technical obstacle
As a result, few researchers have sought industrial use beyond mixing fluids, and few attempts have been made to reduce these pressure losses to optimize their operation

Embodiment Construction

[0061] As indicated above, the principle of the invention consists in the integration of small and reticulated gas / liquid contactors in the form of a three-dimensional network in the reactor through which the gaseous effluent can pass.

[0062] This principle is shown in figure 1 , the figure shows a reactor 1 with a gaseous effluent inlet 11 , said gaseous effluent outlet 12 and a washing liquid injection facility 13 , wherein the reactor integrates a three-dimensional mesh 14 .

[0063] In a manner known per se, the washing solutions are acids, bases and / or basic oxygenates.

[0064] The mesh 14 is present in the form of a three-dimensional metal or plastic (or according to other contemplated embodiments any other material resistant to the washing liquids (acids, bases, oxidizing agents) used) structure consisting of meshes with a side of 1 cm to 10 cm . The strands constituting the contact material have a thickness of 0.5 to 4 mm diameter.

[0065] For low gas flows (e.g...

Abstract

The invention relates to a device for treating a gaseous effluent loaded with odorant compounds, comprising a reactor (1) through which said effluent can pass in transit in the presence of a washing solution, characterized in that said reactor (1) integrates a three-dimensional mesh (14) capable of promoting interfacial exchanges between said effluent and said washing solution.

Description

technical field [0001] The field of the invention is that of deodorisation of gaseous effluents. More specifically, the present invention relates to a technique for deodorizing gaseous effluents by means of a reactor in which the effluents are passed in the presence of a washing liquid. Background technique [0002] Currently, odorous compounds are traditionally removed from air by chemical scrubbing based on acids, bases and / or oxidizing agents in vertical or horizontal columns which may or may not contain packing. [0003] Although this process has so far provided good results in terms of efficacy, there are still running cost issues, especially related to emprise ausol which no one has successfully solved. [0004] This is because the contact times (greater than seconds, taking into account the gas-liquid interfacial exchange area generated) necessary for effective treatment with this type of equipment lead to the construction of large-scale projects, i.e. towers of seve...
