Definitions
- the present invention relates to a method for clean ⁇ ing flue gases generated upon incineration in an incine- rator, especially upon incineration of refuse, in which method the flue gases are conducted through a flue gas duct to an installation for separating particulate impu ⁇ rities.
- active carbon or active coke for separating dioxines and mercury which are present in particular in the flue gases resulting from the incineration of refuse.
- Particulate active carbon or active coke is blown into the flue gas duct.
- the particles of carbon or coke adsorb dioxines and mercury, and are subsequently separated in the separating installation.
- the object of the present invention is, therefore, to provide a simple and inexpensive method for cleaning flue gases, especially of dioxines and mercury.
- this object is achieved by a method which is of the above type and is character- ised by performing soot-generating incineration of a fuel with a deficiency of oxygen; and mixing the generated soot with the flue gases in the flue gas duct.
- the soot-generating incineration can be performed in an incineration unit located outside the flue gas duct.
- the soot-generating incineration can be performed with the aid of a burner unit placed in the flue gas duct.
- An incinerator 1 is supplied with fuel in the form of refuse, such as combustible household waste and indus ⁇ trial waste.
- the flue gases generated upon the refuse incineration contain dioxines and mercury. This invention is especially directed to the separation of precisely dioxines and mercury.
- the flue gases are conducted from the incinerator 1, via a flue gas duct 2, to an installation 3 for separat ⁇ ing gaseous impurities, such as sulphur dioxide and hydro- gen chloride, and then to an installation 4 for separat ⁇ ing particulate impurities (dust).
- the installation 3 is a wet scrubber, but it may also be a contact reactor of some other type.
- the instal ⁇ lation 4 here is a barrier filter unit in the form of a bag filter with textile filter bags, but it may also be an electrostatic dust separator.
- the working tempe ⁇ rature in the barrier filter unit is 60-150°C.
- the f ue gases are conducted from the installation 4 on to other treatment installations before being finally emitted into the atmosphere through a chimney (not shown).
- soot-generating incinera ⁇ tion of a fuel is performed with a deficiency of oxygen.
- the thus-generated soot-laden flue gases are introduced into the flue.gas duct 2 between the gas separator 3 and the dust separator 4.
- the soot particles adsorb dioxines and mercury before being separated in the dust separator 4.
- soot-generating incineration it is much easier and considerably less expensive to thus perform soot-generating incineration according to the invention and use the generated soot for adsorbing dioxines and mercury than to use, for this purpose, active carbon or active coke according to the prior-art tech- nique described in the foregoing.
- the soot- laden flue gases from the unit 5 may, for example, be introduced, into the flue gas duct 2 between the incinera- tor 1 and the gas separator 3.
- the unit 5 can be replaced with a burner provided in the flue gas duct 2 between the dust separator 3 and the dust separator 4 and burning, in soot-generating fashion, a fuel with which it is supplied. Then, the burner raises the temperature in the flue gas duct 2, which confers the advantage that the temperature in the gas separator 3 can be reduced, whereby to increase the degree of separation.

Abstract
Un procédé permet d'épurer des gaz brûlés provenant d'une incinération dans un incinérateur (1), de déchets notamment. Les gaz brûlés sont amenés par une conduite de gaz brûlés (2) vers une installation (4) destinée à la séparation des impuretés particulaires. L'incinération d'un combustible, génératrice de suies, intervient en atmosphère appauvrie en oxygène et les suies se mélangent aux gaz brûlés dans la conduite de gaz brûlés (2).
