Definitions
- the process for the incineration of organic waste relates to a process for the elimination by incineration of organic waste and in particular of liquid or solid organic waste with low calorific value.
- Certain highly polluting organic compositions are very difficult to eliminate. even by incineration. Examples include liquids from leaching operations of steam generators (especially in nuclear reactors), tank bottoms containing organic or colloidal materials, solid materials of the resin type or activated carbon, residual liquids from chemical processes containing styrene ...
- the present invention intends to propose a process for preparing this liquid or solid organic waste so as to place it in a state where their combustion can be carried out quickly and without excessive production of fumes or toxic components.
- the subject of the invention is therefore a process for treating mainly liquid organic waste which consists in producing an aqueous mixture of the substances to be incinerated to which a hydrocarbon of the fuel oil type (optionally charged with a used hydrocarbon that it would be advisable to co-incinerate) and surfactants, to agitate this mixture by incorporating a non-combustible gas therein in order to create a foam and to introduce this foam in a combustion chamber.
- This process is preferably carried out continuously, although it can be applied discontinuously in defined quantities, prepared and burnt.
- the choice of non-combustible gas which can range from carbon dioxide to pure oxygen, makes it possible to act on the risk of auto-ignition of the mixture according to its calorific value.
- the calorific value of the mixture depends on the nature of the effluents to be incinerated and the addition of the fuel, so that by choosing an appropriate gas, we manage to have an inert foam therefore easy to transport to the incinerator .
- the foam When the expansion takes place at atmospheric pressure, the foam is propelled by a pump. It may however be advantageous to carry out an expansion under pressure. Indeed, the pressurized foam while relaxing is self-propelling. Its transport from the place of production, necessarily close to the hearth, to the hearth therefore does not use any pumping device. In addition, it undergoes a violent pressure drop in the conduits emerging at the level of the incinerator, which ensures good dispersion of the organic material to be incinerated in the combustion hearth. This effect is further amplified by the "flash" vaporization of the water contained in the mixture.
- the pressurizing gas is oxygen which can be used if the mixture is of low calorific value
- the excellent division of the mixture contributes to a significant reduction in flame lengths and to an optimization of the smoke volume, in which practically no unburnt remains.
- the smoke flows which result therefrom are therefore minimized, which allows the use, for treating these fumes of very efficient and costly filters, and the absence of unburnt material significantly reduces the frequency of changes of these filters.
- the effluent 2 to be treated is conducted in a mixer 1 where it is supplemented with surfactants 3 and fuel oil 4.
- the effluent is in the form of an aqueous solution of the organic compounds to be eliminated, a contribution additional water 5 can be operated in the mixer 1 to adjust the composition of the mixture.
- the effluent can be the subject of a specific preparation prior to its mixing.
- the other fluids can constitute vectors for the introduction of another product to be incinerated (used oils or the like).
- the latter is then led to the inlet of an enclosure 6 by means of a pump P.
- the enclosure 6 also receives a gas 7 under pressure to create, with agitation, a pressurized foam for example between 2 and 10 bars.
- an inert gas such as carbon dioxide is introduced for a mixture having a very high calorific value or air or air enriched with oxygen or even pure oxygen if it 'is a very little auto-flammable mixture.
- the enclosure or its outlet pipe 8 has a valve V allowing the value of pressurization. Indeed, this valve creates a pressure drop upstream of which, thanks to the pump P, it is possible to maintain this pressure under which this foam is formed.
- This pressure drop may simply consist of the sum of the pressure drop along the pipe 8 and that of the point of the spray nozzle to which this pipe 8 leads.
- the pipe 8 Downstream of this enclosure 6, the pipe 8 opens into a combustion chamber 9 of cyclone type in which the foam completes its expansion.
- the partial expansion taking place in the pipeline constitutes the motor for propelling the foam towards the hearth 9.
- the graph in FIG. 2 is a curve which illustrates the variation in pressure as a function of the specific volume of the product. It is also significant of the pressure of the product circulating continuously in the various parts of the circuit.
- part A of the curve illustrates the increase in pressure in the pump P
- part B relates to the foaming in the enclosure 6
- part C illustrates the pressure of the product in the conduit 8 until it is injected into the combustion hearth 9.
- the oxidizing gas 10 also introduced into the hearth will preferably be oxygen, which makes it possible to avoid the problems relating to the production of nitrogen oxides during combustion in air.
- the expansion is carried out in the enclosure 6 at atmospheric pressure and the valve V is replaced by a foam propulsion pump.
- ashes are collected in an ashtray 10, the nature of which will dictate the subsequent treatment which they will have to undergo.
- effluents from the leaching of nuclear units these ashes will be contaminated and it will be useful to "block" them in a coating matrix before final storage in an approved site.
- the combustion fumes 11 are cooled in a cooler.
- straightener 12 which condenses the water vapor they contain to get rid of them. They are then passed through filters 13 suitable for very high efficiency which retain all the unwanted particles in an atmospheric discharge. If necessary, intermediate heating can be provided to raise the dew point to avoid condensation on the cold walls of the filters.
- Reference 14 represents the removal of the particles (and of the filters which are charged with them), 15 being the representation of the path of discharge into the atmosphere. It is also possible to provide an afterburner 17 following the furnace 9.
- the fuel is prepared in the form of foam, preferably pressurized which allows to adjust the inerting of the product as a function of the initial mixture, which makes it possible to find a compromise between the safety against self-ignition to be ensured during transport and the ease of incineration.
- this foam has from the point of view of its transport and its combustion thanks precisely to this structure in the form of foam, the combustion is of the gas type and its stoichiometry can easily be adjusted.
- the short flames and the complete combustion which one notes, in particular when one operates in the presence of pure oxygen, allows a significant reduction in the dimensions of the combustion hearth. It then becomes possible to provide the unit which implements the method is movable 1'invention 'and can be approached from the place where are produced the effluent (which eliminates all the problems associated with transportation and intermediate storage ).
- the effluent to be burned may contain solid particles in suspension, these being supported by the frothy structure created. These particles can therefore be trapped with the effluent to like a charged foam, that is to say a solid three-phase structure - liquid - gas. If necessary, prior grinding of the charged effluent will have been carried out to adjust the particle size of the solids.
- the foams are self-cleaning (in the case where they are tank leaching products or steam generators) which makes maintenance of the installation easy.
- the process of the invention is all the more advantageous since it is versatile. Indeed, by the transformation of the effluents to be incinerated into foam (charged or not) and pressurized, it is applicable to a wide variety of products. This foam is also easily modifiable in its composition, which allows precise adjustment of its formulation and control of the combustion temperature.
- the preparation of the foam was carried out from this effluent added with fuel oil to obtain a final product having 90% of effluent, 10% of fuel oil by weight.
- the incineration of 570 kg / h of this oxygen pressurized foam with 250 kg / h of oxygen as oxidizer (including a 10% excess compared to stoichiometry) produced fumes containing mainly 1/4 of C0 2 , and 2/3 of H 2 0. We see the high proportion of water in these fumes which, once condensed, allows a very significant reduction volumes to be filtered.
