PROCEDE ET BATIMENT POUR LE SECHAGE D'UNE MASSE VEGETALE
EN DECOMPOSITION
La présente invention concerne le séchage d'une masse végétale en décomposition.PROCESS AND BUILDING FOR DRYING A PLANT MASS
IN DECOMPOSITION
The present invention relates to the drying of a decomposing plant mass.
Par masse végétale en décomposition", on entend toute matière végétale susceptible de se décomposer sous l'action anaérobie de micr -organismes, présents dans la matière,ou ensemencés à cette fin. I1 s'agit en particulier de résidus végétaux,tels que fumiers,composts,etc. The term “decomposing plant mass” means any plant material capable of decomposing under the anaerobic action of micro-organisms, present in the material, or seeded for this purpose. They are in particular plant residues, such as manure , composts, etc.
Cette décomposition génère un liquide résiduaire, par exemple' du lisier, qu'il est nécessaire d'évacuer par séchage,si l'on veut disposer d'une matière fertilisante prête à l'emploi, par exemple pour amender des sols pour la culture.This decomposition generates a residual liquid, for example 'slurry, which it is necessary to evacuate by drying, if one wants to have a fertilizing material ready for use, for example to amend soils for cultivation .
Dans la pratique, et afin d'économiser lténergie thermique nécessaire au séchage, il est connu de disposer la masse végétale en décomposition, dans une enceinte de séchage type serre,éclairée par la lumière naturelle.In practice, and in order to save the thermal energy necessary for drying, it is known to arrange the decomposing plant mass, in a greenhouse-type drying enclosure, lit by natural light.
Un tel procéde naturel conduit pour des masses végétales de forte epaisseur, soit à un séchage imparfait - le "coeur" de la masse reste imprégné du liquide résiduaire-, soit à un temps de séchage complet beaucoup trop long, eu égard aux impératifs d'une production industrielle.Such a natural process leads to very thick plant masses, either to imperfect drying - the "core" of the mass remains impregnated with the residual liquid, or to a complete drying time which is much too long, having regard to the requirements of industrial production.
La présente invention a pour objet un procédé de séchage "à coeur" d'une masse végétale en décomposition dans un temps raisonnable. The subject of the present invention is a process for drying "to the core" of a decomposing plant mass in a reasonable time.
Selon la présente invention, on distribue et on insuffle de l'air dans la masse végétale en décomposition,par sa partie inférieure,et on récupère le liquide résiduaire, également par la partie inférieure de la même masse , et l'air traversant cette dernière est évacué par le haut de l'enceinte de séchage. According to the present invention, air is distributed and blown into the decomposing plant mass, by its lower part, and the residual liquid is recovered, also by the lower part of the same mass, and the air passing through the latter. is discharged from the top of the drying chamber.
La présente invention est maintenant décrite par référence aux dessins annexés, dans lesquels
- la figure 1 représente une vue en élévation d'un batiment conforme à la présente invention,du type serre, du côte de la façade de pignon par laquelle il est possible d'accéder à l'intérieur du bâtiment
- la figure 2 représente une vue en coupe horizontale selon la ligne II-II de la figure 1 du batiment re présenté à cette'dernière ; pour pour la bonne compréhension de l'invention, les grilles disposées sur les rigoles et caniveaux de la plate-forme ont été retirées
- la figure 3 représente une vue en coupe verticale selon la ligne III-III de la figure 2, la structure aérienne du batiment, à savoir la serre, ayant été supprimée de cette représentation.The present invention is now described with reference to the accompanying drawings, in which
- Figure 1 shows an elevational view of a building according to the present invention, of the greenhouse type, from the side of the gable facade through which it is possible to access the interior of the building
- Figure 2 shows a horizontal sectional view along line II-II of Figure 1 of the building re presented to this last; for the understanding of the invention, the grids arranged on the channels and gutters of the platform have been removed
- Figure 3 shows a vertical sectional view along line III-III of Figure 2, the aerial structure of the building, namely the greenhouse, having been removed from this representation.
Un batiment selon l'invention comprend
- une plate-forme (1) en béton,rectangulaire , com- portant une pluralité de canaux transversaux (2),distribués selon la longueur, disposés selon la largeur de la dalle;ces canaux consistent en des rigoles (3) inclinées chacune selon la largeur de la dalle,pour l'écoulement du liquide résiduaire,comme décrit ci-après; chaque rigole (2) est couverte par une grille (3),ou une pluralité de grilles,lesquelles sont perméables à l'air insufflé,et au liquide résiduaire,et servent de support à la masse végétale (4) ;
- un moyen d'alimentation (5) et de distribution d'air dans les canaux, consistant en un caniveau distributeur à ciel ouvert, orienté selon la longueur de la dalle, couvert également par une grille, raccordé à .toutes les rigoles (2) précédemment décrites
- un moyen (6) de collecte et d'évacuati-on du liquide résiduaire, consistant en un caniveau collecteur à ciel ouvert, couvert également par une grille, incliné lui-même vers la sortie (7) du liquide résiduaire,auquel sont raccordées toutes les rigoles (2), à l'opposé du caniveau (5)
- une structure (8), du type serre, dispose sur la plate-forme (1), formant l'enceinte de séchage, comportant des portes latérales (8) et (9) d'accès à la serre, et une ouverture supérieure (11) d'aération , de manière traditionnelle, la serre (8) comporte une succession d'arceaux (12),encastrés dans un muret (13) périphérique, sur lesquels une paroi transparente, par exemple en verre, est fixée de manière appropriée.A building according to the invention comprises
- a rectangular concrete platform (1) comprising a plurality of transverse channels (2) distributed along the length, arranged along the width of the slab; these channels consist of channels (3) each inclined according to the width of the slab, for the flow of the residual liquid, as described below; each channel (2) is covered by a grid (3), or a plurality of grids, which are permeable to the blown air, and to the residual liquid, and serve as a support for the plant mass (4);
- a means of supply (5) and air distribution in the channels, consisting of an open air distributor channel, oriented along the length of the slab, also covered by a grid, connected to .all the channels (2 ) previously described
- A means (6) for collecting and evacuating waste liquid, consisting of an open-air collecting channel, also covered by a grid, inclined itself towards the outlet (7) of the residual liquid, to which are connected all channels (2), opposite the channel (5)
- a structure (8), of the greenhouse type, arranged on the platform (1), forming the drying enclosure, comprising side doors (8) and (9) for access to the greenhouse, and an upper opening (11) ventilation, in a traditional way, the greenhouse (8) comprises a succession of arches (12), embedded in a low wall (13), on which a transparent wall, for example glass, is fixed so appropriate.
Selon la description précédente, chaque rigole (2) est inclinée du caniveau distributeur (5) d'air insufflé vers le caniveau (6) collecteur du liquide résiduaire, et la sortie (7) de ce dernier est strictement adaptée au seul écoulement dudit liquide, par exemple au moyen d'un clapet susceptible de se fermer sous l'action d'une pression d'air, de manière à distribuer l'air insufflé au travers des rigoles (2) et des grilles (3), cet air étant introduit par l'entrée (14). According to the preceding description, each channel (2) is inclined from the distributor channel (5) of blown air towards the channel (6) collecting the residual liquid, and the outlet (7) of the latter is strictly adapted to the flow of said liquid only. , for example by means of a valve capable of closing under the action of air pressure, so as to distribute the blown air through channels (2) and grids (3), this air being introduced by the entrance (14).
Selon un autre mode d'exécution de l'invention, on obture les rigoles (2),.à leurs extrémités opposées au caniveau (5) d'introduction de l'air, et une sortie du liquide résiduaire est prevue sur ce dernier, à l'opposé de l'entrée d'air (14). According to another embodiment of the invention, the channels (2) are closed off, at their ends opposite the channel (5) for introducing air, and an outlet for the residual liquid is provided on the latter, opposite the air inlet (14).
Un batiment tel que précédemment décrit, peut être exploité de manière suivante. En pénétrant par la porte d'accès (9) ou (10), par exemple au moyen d'un tracteur agricole, on peut déposer une masse végétale à décomposer, par exemple du fumier ou du compost sur la plateforme, et en particulier sur les grilles (3) recouvrant les rigoles (2) aussi bien que les caniveaux (5) et (6). A building as previously described can be operated in the following manner. By entering through the access door (9) or (10), for example by means of an agricultural tractor, a plant mass to be decomposed can be deposited, for example manure or compost on the platform, and in particular on the grids (3) covering the channels (2) as well as the gutters (5) and (6).
Une fois les portes (9) et (10) fermées, on insuffle de l'air par l'entrée (14), par tous moyens appropriés, par exemple au moyen d'un ventilateur, et l'air insufflé est distribué par le caniveau (5) dans toutes les rigoles (2) ; la sortie (7) étant réservée uniquement au lisier, l'air insufflé et distribué s'évacue principalement par les grilles (3), par la partie inférieure de la masse végétale (4) en décomposition. Quant au lisier, il s'écoule graduellement dans les différentes rigoles (2) en pente douce, vers le caniveau collecteur (6), puis il est évacué par la sortie (7). Once the doors (9) and (10) are closed, air is blown in through the inlet (14), by any suitable means, for example by means of a fan, and the blown air is distributed by the channel (5) in all the channels (2); the outlet (7) being reserved only for slurry, the blown and distributed air is evacuated mainly by the grids (3), by the lower part of the decomposing plant mass (4). As for the slurry, it gradually flows in the various channels (2) gently sloping, towards the collecting channel (6), then it is evacuated by the outlet (7).
Afin d'accélérer le séchage, on pénètre périodiquement par la porte (9) ou (10), avec un moyen mécanique, permettant de remuer la masse (4) en cours de décomposition et de séchage, ce qui permet de renouveler les différentes couches de cette dernière au contact de l'air insufflé. In order to accelerate the drying, one enters periodically through the door (9) or (10), with a mechanical means, allowing to stir the mass (4) during decomposition and drying, which makes it possible to renew the different layers of the latter in contact with the blown air.
