Abstract

A vat for anaerobic fermentation of a biomass to form methane comprises a vessel with an offtake level to limit the liquid contents to about 2/3 of the vat capacity so that the upper part of the vat can also act as a pressurised methane reservoir. The vat is lined with an impermeable layer of butyl rubber backed by a layer of thermal insulation material and a supporting structure of e.g. steel, concrete. The top of the vat is fitted with outlets for gas extraction, relief valves, pressure gauges, etc. The lower part of the vat has fluid entry and drainage ports.

Description

L'invention a trait à une cuve de fermentation de la biomasse pour itobtention de combustibles gazeux tel que le méthane en tant que source d'énergie et, notamment à une cuve réalisée en matière synthétique. The invention relates to a biomass fermentation tank for obtaining gaseous fuels such as methane as an energy source and, in particular to a tank made of synthetic material.

En raison des difficultés d'approvisionnement et du coût du pétrole, les sources d'énergie secondaires prennent de plus en plus de ltessort et, notamment les différentes possibilités offertes par le gaz naturel. Or, un des éléments essentiels du gaz naturel est le méthane et on a pensé à procéder à la fermentation méthanique de la biomasse. A cet effet, les différentes installations utilisent une première série de cuves dans lesquelles se réalise la fermentation et une seconde série servant de gazomètres. I1 est nécessaire de prévoir des fondations, ce qui entraîne des frais de génie civil relativement importants. En raison de la dualité des cuves, on risque une rupture entre une cuve de fermentation et une cuve servant de gazomètre.En plus des risques d'incidents plus ou moins graves, une telle rupture provoque une perte d'énergie pouvant nuire au fonctionnement correct d'une installation. Because of supply difficulties and the cost of petroleum, secondary energy sources are becoming more and more essential, and in particular the various possibilities offered by natural gas. One of the essential elements of natural gas is methane and we have thought of carrying out the methane fermentation of biomass. For this purpose, the various installations use a first series of tanks in which fermentation takes place and a second series serving as gasometers. It is necessary to provide foundations, which involves relatively high civil engineering costs. Due to the duality of the tanks, there is a risk of a rupture between a fermentation tank and a tank serving as a gasometer. In addition to the risks of more or less serious incidents, such a rupture causes a loss of energy which can affect correct operation. of an installation.

La présente invention a pour but de fournir une cuve présentant une structure telle qu'elle assure simultanément la fonction d'une cuve de fermentation et la fonction d'un gazomètre, notamment pour du méthane obtenu par suite de la fermentation de la biomasse. The present invention aims to provide a tank having a structure such that it simultaneously performs the function of a fermentation tank and the function of a gasometer, especially for methane obtained as a result of the fermentation of biomass.

A cet effet, l'invention concerne une cuve de fermentation de la biomasse pour 11 obtention de combustibles gazeux tel que le méthane en tant que source d'énergie et, notamment à une cuve réalisée en matière synthétique caractérisée en ce qu elle comporte une poche en matériau souple tel que le butyl présentant deux compartiments de traitements superposés sans séparation et dont le volume est calculé en fonction du volume de biomasse à traiter, cette poche pouvant être ou non enrobée d'une première ceinture en matière isolante et d'une seconde ceinture en matériau dur pour compenser les pressions latérales. To this end, the invention relates to a biomass fermentation tank for obtaining gaseous fuels such as methane as an energy source and, in particular to a tank made of synthetic material, characterized in that it includes a pocket. flexible material such as butyl having two compartments of treatment superimposed without separation and whose volume is calculated according to the volume of biomass to be treated, this pocket may or may not be coated with a first belt of insulating material and a second hard material belt to compensate for lateral pressures.

L'invention présente plusieurs avantages et, notamment aucun génie civil ntest nécessaire pour l'installation de cette cuve puisque celle-ci peut être disposée sur le sol nu. Du fait que la poche présente deux compartiments dont l'un sert de digesteur et l'autre de gazomètre, on élimine tout risque de rupture entre la cuve de fermentation et le gazomètre. The invention has several advantages and, in particular, no civil engineering is necessary for the installation of this tank since it can be placed on bare ground. Because the pocket has two compartments, one of which serves as a digester and the other as a gasometer, any risk of rupture between the fermentation tank and the gasometer is eliminated.

L'invention sera bien comprise en se référant à la description suivante faite à titre d'exemple non limitatif et au dessin ci-annexé dans lequel - la figure unique est une vue en élévation en coupe d'une cuve de fermentation conforme à l'invention. The invention will be better understood by referring to the following description given by way of nonlimiting example and to the attached drawing in which - the single figure is a sectional elevation view of a fermentation tank in accordance with invention.

La cuve 1 comporte une carcasse en matériau dur 2 ayant la forme d'une ceinture et dont le chant inférieur 3 repose sur le sol 4 ou sur un feutre ou autre matière isolante anti-poinçonnage et imputrescible. The tank 1 comprises a carcass of hard material 2 having the shape of a belt and the lower edge 3 of which rests on the ground 4 or on a felt or other insulating material which is anti-punching and rot-proof.

Le matériau dur utilisé peut être du fer, du béton, du talutage ou autres pour compenser toute pression latérale.The hard material used can be iron, concrete, sloping or the like to compensate for any lateral pressure.

La face interne 5 de cette carcasse 2 est pourvue d'une ceinture en matière plastique ou autre isolante 6 ayant une hauteur identique à celle de la carcasse 2. Cette ceinture en matière plastique ou autre isolante renferme une poche en matière plastique 7 réalisée de préférence en butyl. Cette poche 7 sert, à sa partie inférieure, de premier compartiment 8 renfermant la biomasse soumise à la fermentation. Au-dessus de cette biomasse, cette poche sert de second compartiment 9 dans lequel peut s'amasser le méthane dû à la fermentation de la biomasse. Ce second compartiment 9 peut servir de gazomètre. The internal face 5 of this carcass 2 is provided with a plastic or other insulating belt 6 having a height identical to that of the carcass 2. This plastic or other insulating belt contains a plastic bag 7 preferably made butyl. This pocket 7 serves, at its lower part, as the first compartment 8 containing the biomass subjected to fermentation. Above this biomass, this pocket serves as a second compartment 9 in which the methane can accumulate due to the fermentation of the biomass. This second compartment 9 can serve as a gasometer.

La poche en butyl 7 comporte à sa partie inférieure 10 une entrée des matières 11. Cette entrée 11 est pourvue d'un siphon et d'une vanne non représentés dans la figure. Par ailleurs, cette poche 7 comporte une sortie de matière 12 située aux deux tiers environ de la hauteur de la poche 7, sortie avec siphon et vanne non représentés dans la figure. Le niveau supérieur 13 de la biomasse est à fleur par rapport à la sortie 12. The butyl pocket 7 has at its lower part 10 an inlet for materials 11. This inlet 11 is provided with a siphon and a valve not shown in the figure. Furthermore, this pocket 7 has a material outlet 12 located about two thirds of the height of the pocket 7, outlet with siphon and valve not shown in the figure. The upper level 13 of the biomass is flush with the outlet 12.

Le fond de cette poche 7 est pourvu de deux prises à la base 14, 15 permettant, d'une part, le brassage et, d'autre part, la vidange des matières. The bottom of this pocket 7 is provided with two sockets at the base 14, 15 allowing, on the one hand, the mixing and, on the other hand, the emptying of the materials.

Le plafond 16 de la poche 7 comporte quatre manchons 17, 18, 19, 20. L'un des manchons 17, par exemple, sert de sortie pour le gaz renfermé dans le second compartiment 9 alors que deux autres manchons, par exemple 18 et 19, permettent la mise en place de clapets de surpression et autres appareils de sécurité alors que le dernier manchon 20 est un sas pour introduire dans la poche 7 des instruments de mesure. The ceiling 16 of the pocket 7 has four sleeves 17, 18, 19, 20. One of the sleeves 17, for example, serves as an outlet for the gas contained in the second compartment 9 while two other sleeves, for example 18 and 19, allow the installation of pressure relief valves and other safety devices while the last sleeve 20 is an airlock for introducing into the pocket 7 of the measuring instruments.

On peut également prévoir un chauffage par tuyaux souples pour conférer à l'ensemble une certaine température et, de ce fait, activer la fermentation. Ce chauffage peut être placé sur le fond de la poche 7. One can also provide heating by flexible pipes to give the whole a certain temperature and, therefore, activate the fermentation. This heater can be placed on the bottom of the pocket 7.

Inversement, le chauffage peut être situé en dehors et la poche 7 repose sur ledit chauffage. Conversely, the heater can be located outside and the pocket 7 rests on said heater.

Selon un autre mode de réalisation, on peut prévoir un socle renfermant le chauffage et sur lequel est posée la cuve 1. According to another embodiment, a base can be provided containing the heating and on which the tank 1 is placed.

Bien que l'invention ait été décrite a propos d'une forme de réalisation particulière, il est bien entendu qu'elle n'y est nullement limitée et qu'on peut y apporter diverses modifications de formes, de matériaux et de combinaisons de ces divers éléments, sans pour cela s'éloigner du cadre et de l'esprit de l'invention. Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to the forms, materials and combinations of these. various elements, without departing from the scope and spirit of the invention.
