Abstract

Appts. is claimed for the disposal of highly polluted effluent and the prodn. of humus. The effluent is percolated through a bed of organic, partic. cellulosic, waste counter current to a stream of heated air rising through the bed. Vapour rising from the bed is condensed and the condensate is circulated through the battery of a heat exchanger to pre-heat air to be blown through the bed. Used for disposing of highly conc. industrial effluent combined with the bio-digestion of organic, partic. cellulosic waste. Humus for agricultural fertilisation is produced by fermentation of the waste fortified with residue from the effluent. Appts. is partic. suitable for handling effluent from factories using evapn. for thermal concn. The effluent is eliminated with polluting the atmos. with an objectionable smell. The prodn. of humus is made viable by recycling heat of condensate to preheat incoming air.

Description

Dispositif thermo-blo-digesteur pour la dépollution d'effluents liquides et la production d'humus. Thermo-blo-digestor device for the depollution of liquid effluents and the production of humus.

Il est destiné au traitement des effluents à forte concentration en vue de récupérer les sous Droduits des usines fonctionnant sous concentration thermique par évaporateurs. It is intended for the treatment of high concentration effluents with a view to recovering the by-products of factories operating under thermal concentration by evaporators.

Actuellement, le coût de l'énergie consommée par ces installations condamne leur exploitation. Les digesteurs anaérobie demandent de très importants investissements et exilent tant en amont qu'en aval des installations comolémentaires. C'est ainsi que les distilleries vinicoles ont essayé de résoudre le problème du coût énergétique en pratiquant des traitements physicochimiques suivi de lagunages à évaporation, mais ces installations répandent de mauvaises odeurs sans pour cela permettre la valorisation des sous produits. Currently, the cost of the energy consumed by these installations condemns their exploitation. Anaerobic digesters require very large investments and exile both upstream and downstream of additional facilities. This is how the wine distilleries tried to solve the problem of energy cost by practicing physicochemical treatments followed by evaporative lagooning, but these installations spread bad smells without allowing the recovery of by-products.

Le dispositif suivant l'invention supprime ces inconvénients et permet de diminuer dans des proportions considérables la consommation d'énergie, tout en donnant la possibilité de valoriser les déchets ainsi que de produire une énergie calorifique. The device according to the invention eliminates these drawbacks and makes it possible to considerably reduce energy consumption, while giving the possibility of recovering waste as well as of producing heat energy.

Il est constitué par l'appareillage assurant le bouclage de la ventilation qui permet l'évaporation, la condensation, l'effacement de la pollution liquide et l'utilisation des calories cédées à l'eau condensée. It is made up of the equipment ensuring the ventilation loop which allows evaporation, condensation, erasing of liquid pollution and the use of calories given up in condensed water.

Sur le dessin annexé, donné à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention, le dispositif est représenté dans son ensemble vu en coupe et en élévation. In the attached drawing, given by way of nonlimiting example, of one of the embodiments of the object of the invention, the device is shown as a whole seen in section and in elevation.

D'après la représentation donnée, la trémie 1 alimente le caisson-tunnel 2 en déchets cellulosiques et ligneux. According to the representation given, the hopper 1 supplies the box-tunnel 2 with cellulose and wood waste.

La masse des matières tractées peut contenir des raffles utilisées comme substrat de ruissellement et de filtration, des vinasses de distillations viticoles, des concentrés d'usines agro-alimentaires, etc... est engaaée sur une couche réglable d'environ deux mètres de hauteur. Cette couche est tractée sur un plancher perforé 3 par un ensemble de chaînes et traverses 4, 4'.  The mass of towed material can contain raffles used as a runoff and filtration substrate, vinasse from wine distillations, concentrates from food processing factories, etc ... is engaaée on an adjustable layer of about two meters in height . This layer is towed on a perforated floor 3 by a set of chains and crosspieces 4, 4 '.

L'effluent liquide est collecté en 5 et arrose modérément la masse 2 en déplacement par l'intermédiaire de rampes 6, 6 ,
Un soufflage par ventilateurs 7, 8, 9, 10, est organisé de façon à recycler par 11, ll', 12, 13, sur des batteries de chauffe 14, 15, 16, 17, et permettre d'admettre ainsi de l'air neuf 18, 19, 20, 21 tout en évacuant du gaz par 22, 23, 24.The liquid effluent is collected in 5 and moderately sprinkles the moving mass 2 by means of ramps 6, 6,
A blowing by fans 7, 8, 9, 10, is organized so as to recycle by 11, ll ', 12, 13, on heating batteries 14, 15, 16, 17, and thus allow to admit fresh air 18, 19, 20, 21 while discharging gas through 22, 23, 24.

Les batteries par les conduits 25, 26, 27, 28 dépouillent les calories prélevées par la condensation de la vapeur d'eau entraînée par les recyclages sont piégées dans les récupérateurs à condensation 29, 30, 31. The batteries through the conduits 25, 26, 27, 28 strip the calories taken up by the condensation of the water vapor entrained by the recycling are trapped in the condensing recuperators 29, 30, 31.

Les boucles d'eau pulsées par ces pompes 32, 33, 34 après avoir cédé les calories sur l'air des batteries 14, 15, 16, 17, sont remontées aux condenseurs 29, 30, 31 pour être pulvérisées en tête. Les trop pleins représentent l'évaporation. The water loops pulsed by these pumps 32, 33, 34 after having transferred the calories to the air in the batteries 14, 15, 16, 17, are raised to the condensers 29, 30, 31 to be sprayed at the head. The overflows represent evaporation.

Le compartiment de sortie du tunnel 35, correspond à la zone de séchage de la bio-masse décomposée qui pourra être conditionnée 36 pour sa commercialisation. The exit compartment of the tunnel 35 corresponds to the area for drying the decomposed biomass which can be conditioned 36 for marketing.

Cet ensemble constitue une application industrielle à production continue et automatisée. Ce procédé de traitement peut s'appliquer à une ou plusieurs chambres statiques à chargemment discontinu, en rotations espacées en fonction des temps de digestion et de décomposition. This set constitutes an industrial application with continuous and automated production. This treatment process can be applied to one or more static chambers with batch loading, in spaced rotations as a function of the digestion and decomposition times.

Toutefois les formes, dimensions et dispositions des différents éléments comme d'ailleurs les matières utilisées pour leur fabrication, pourront varier dans la limite des équivalents, sans changer pour cela la conception générale de l'invention qui vient d'être décrite.  However, the shapes, dimensions and arrangements of the various elements, as indeed the materials used for their manufacture, may vary within the limit of equivalents, without thereby changing the general conception of the invention which has just been described.
