Abstract

A charcoal making installation has two furnaces without floors of which one carbonises wood and the other dries wet wood, a gas incinerator connected to the carbonisation furnace and in turn connected by a gas injector to an extractor, a scrubber downstream of the extractor, and a duct conveying hot gas from the incinerator to the dryer with a cool gas injector regulating the temp. of the dryer. A method of making charcoal is also claimed.

Description

Le présent certificat d'addition concerne la rcupration des calories engendrées par l'utilisation du système d'élimination des gaz issus de la carbonisation des bois - Brevet d'invention 85 15238 - dans lequel deux des trois revendications se rattachent au présent objet l'utiljsation de l'incinérateur récupérateur d'enérgie et le ventilateur extracteur.This certificate of addition relates to the recovery of the calories generated by the use of the system for eliminating gases from the carbonization of wood - Patent of invention 85 15238 - in which two of the three claims relate to this subject matter. use of the energy recovery incinerator and extractor fan.

Le domaine technique où peut s'appliquer cette extension concerne les chantiers de carbonisation munis d'un incinérateur thermique de dépollution des gaz.The technical field where this extension can be applied concerns carbonization sites equipped with a thermal gas depollution incinerator.

Les normes actuelles de rejets dans l'atmosphère ne permettent plus la carbonisation libre, mais l'oblige à s'effectuer à travers un système ddpolluant thermique, tel que nous l'avons conçu et breveté.Current standards of atmospheric discharges no longer allow free carbonization, but oblige it to be carried out through a thermal pollution control system, as we have designed and patented it.

Cependant les bois ne peuvent valablement se carboniser qu'à 25 50 maximum d'humidité; D'où l'utilisation prioritaire des gaz chauds de cet incinèrateur pour le séchage accéléré des bois en carbonisation.However, wood can only be properly charred at 25 to 50 humidity maximum; Hence the priority use of hot gases from this incinerator for accelerated drying of charred wood.

Précédement, il était indispensable de stocker les bois, pour un séchage à l'air libre, pratiquement un an avant leur utilisation en carbonisation, ce temps pouvant varier en plus ou en moins selon la situation géographique, lew saisons, l'exposition au vent et au soleil, la disposition du stockage.Previously, it was essential to store the wood, for drying in the open air, practically a year before their use in charring, this time may vary more or less depending on the geographic location, the seasons, exposure to the wind and in the sun, the storage layout.

Ce stockage coûte naturellement très cher ! Quelques éssais ont bien été tentés pour utilisé directement les gaz de carbonisation d'un four vers un autre, en attente.This storage is naturally very expensive! Some attempts have been made to use carbonization gases directly from one oven to another, pending.

Le fait que ces gaz ne soient pas "craqués" préalablement engendraient un dépot de goudrons dans les conduits, au moment du refroidissement de ces gaz, en contact avec la masse froide du four à sécher.The fact that these gases are not "cracked" beforehand caused a deposit of tar in the conduits, at the time of the cooling of these gases, in contact with the cold mass of the oven to be dried.

Autre part les gaz de carbonisation n'ont pas une valeur calorifique constante : faible en début ils deviennent plus riches en phase exothermiques. On the other hand, carbonization gases do not have a constant calorific value: low at the start they become richer in the exothermic phase.

Le passage dans un incinérateur supprime ces inconvdnients d'autant que plusieurs fours sont en varbonisation simultanée, apportant ainsi une utilisation permanente des calories. D'autre part, les gaz de carbonisation sous une température de 8000 sont devenus propres par élimination des goudrons pyroligneux.The passage through an incinerator eliminates these disadvantages especially as several ovens are in simultaneous varbonisation, thus bringing a permanent use of calories. On the other hand, the carbonization gases at a temperature of 8000 became clean by elimination of the pyroligneous tars.

Dans la déscription de notre demande de brevet 85 15238 page 2 ligne 2425-26 nous évoquions déjà les ressources importantes en calories que libérait l'incinérateur pendant son fonctionnement.In the description of our patent application 85 15238 page 2 line 2425-26 we already mentioned the significant calorie resources that the incinerator released during its operation.

Dans bons nombres de cas, il reste en disponible une quantité importante de ces calories, que le pré-séchage n'exige plus, on peut alors les utiliser soit en chauffage domestique, soit en utilisation particulière. In good numbers of cases, there remains available a significant quantity of these calories, which the pre-drying does not require any more, one can then use them either in domestic heating, or in particular use.

Celle qui intéressent plus spécialement notre activité, est la fabrication des bois torréfiés "3ois Roux" dont le besoin en calories permanentes justifie l'utilisation du surplus de calories fournies gratuitement par le dépollueur.The one that interests our activity more specifically, is the manufacture of "3ois Roux" roasted woods, whose need for permanent calories justifies the use of the extra calories supplied free of charge by the depolluter.

Le principe de notre dispositif est le suivant : un four type meule metallique n0(1)est en carbonisation. Une dépression provoquée par un ventilateur(4)aspire les gaz de carbonisation dans la gaine ouverte(11) puis dans le collecteur(22)fait pénétrer ces gaz par l'ouverture(23) dans l'incinérateur(2 > où ils sont détruits sous 800/9000 en auto-combustion.The principle of our device is as follows: an oven type metal grinding wheel n0 (1) is in carbonization. A vacuum caused by a fan (4) sucks the carbonization gases in the open sheath (11) then in the collector (22) makes these gases penetrate through the opening (23) in the incinerator (2> where they are destroyed under 800/9000 in self-combustion.

Ilx ressortent en bout de l'incinérateur.. They come out at the end of the incinerator.

Le ventilateur(4) après dilution avec air frais dans le mélangeur(41)pousse l'air sec et chaud dans le collecteur(5) par le clapet53)cet air est distribué jusqu'à l'orifice(33) du four n0(3) en séchage. L'air chargé d'eau est refoulé à l'extérieur par le clapet(32)
En fonction de lataille de l'incinérateur un nombre indétérminé de fours en carbonisatioh (identique à 1) sont reliès au collecteui22)- un même nombre de fours en séchage (identique à 3) sont reliès au collecteur(5)par le Jeu dea clapets, les fours séchés, sans aucune autre manutention, sont protes à la carbonisation et au séchage des autres fours disposés en échange des fours términés.The fan (4) after dilution with fresh air in the mixer (41) pushes the dry and hot air into the manifold (5) by the valve53) this air is distributed to the orifice (33) of oven n0 ( 3) drying. The air charged with water is discharged outside by the valve (32)
Depending on the size of the incinerator an indeterminate number of carbonisatioh ovens (identical to 1) are connected to the collector22) - the same number of drying ovens (identical to 3) are connected to the collector (5) by the valve game , the dried ovens, without any other handling, are protected against carbonization and drying of the other ovens arranged in exchange for the finished ovens.

Le process se renouvelle indéfiniment.The process is repeated indefinitely.

Dans certains cas d'installations importantes, les gaz brulés sont rejetés à l'atmosphère en surplus. Ils peuvent alors être repris dans un torréfactwur,(6) utilisant alors la production de calories gratuites.In some large installations, the flue gases are released to the surplus atmosphere. They can then be taken up in a roastwur, (6) using the production of free calories.

Cette dernière utilisation n'est pas limitative, uns quantits d'autres étant possible. Chauffage de locaux, habitations-serres-Turbines-ets... This latter use is not limiting, some quantities being possible. Heating of premises, dwellings-greenhouses-Turbines-ets ...
