Description
Cette invention se caractérise par un procédé utilisant l'oxydationThis invention is characterized by a process using oxidation
thermique comme élément d'élimination, soit des nuisances olfactives, soit des composés organiques volatils. as an element of elimination, either olfactory nuisances or volatile organic compounds.
Cette invention relative à une torchère d'élimination des nuisances olfactives atmosphériques apporte d'importantes améliorations par rapport aux modèles existants. Elle est apte à assainir une masse non négligeable de produit à traiter dans un volume très petit, donc d'un prix de revient inférieur à ceux proposés sur le marché actuel. Des expérimentations ont été effectuées pour prouver le bien-fondé de cette innovation. On a pu constater qu'une chambre de combustion d'un diamètre de 100mm sur une longueur de 500mm permet de traiter un volume de 100m3/heure. Ces dimensions ne sont qu'indicatives et, non limitatives. This invention relating to a flare for eliminating atmospheric olfactory nuisances provides important improvements over existing models. It is able to sanitize a sizeable mass of product to be processed in a very small volume, therefore a lower cost price than those offered on the current market. Experiments have been carried out to prove the validity of this innovation. It has been found that a combustion chamber with a diameter of 100mm over a length of 500mm can treat a volume of 100m3 / hour. These dimensions are only indicative and non-limiting.
L'oxydation thermique a été assurée par l'apport de propane enflammé dès son introduction dans la chambre de combustion. Il a été constaté que la température des gaz à l'intérieur de celle-ci était proche de 800 C et que malgré la petitesse de la chambre de combustion aucune flamme ne sortait de la tubulure d'évacuation des gaz brûlés. The thermal oxidation was ensured by the intake of ignited propane as soon as it was introduced into the combustion chamber. It was found that the temperature of the gases inside of it was close to 800 C and that despite the smallness of the combustion chamber no flame was coming out of the exhaust pipe of the burnt gases.
Selon des modes particuliers de réalisation, cet appareil est constitué par deux arrête-flammes, l'un étant disposé à l'entrée des gaz à traiter, ayant le rôle de sécurité dans le cas où le produit à traiter serait porteur d'un produik inflammable tel que du méthane ou autre composant, le second étant disposé à la sortie de la tubulure d'évacuation des gaz brûlés. Par sa position, il freine l'évacuation de ces gaz et permet un accroissement de la température de combustion. En sortie des gaz brûlés, il est possible d'ajouter en série, un ou plusieurs arrête-flammes permettant ainsi d'obtenir une plus grande pureté du produit à traiter. According to particular embodiments, this apparatus is constituted by two flame arresters, one being disposed at the inlet of the gases to be treated, having the role of safety in the case where the product to be treated is carrying a product. flammable such as methane or other component, the second being disposed at the outlet of the exhaust gas discharge pipe. By its position, it slows the evacuation of these gases and allows an increase in the combustion temperature. At the outlet of the flue gases, it is possible to add in series, one or more flame arrestors thus making it possible to obtain a greater purity of the product to be treated.
Cet appareil est constitué par une pièce maîtresse métallique, sous l'appellation: chambre de compression (1) ayant plusieurs fonctions: en partie basse (A) elle canalise le gaz à traiter par l'intermédiaire d'un coupe-flammes (2), puis ce gaz est légèrement comprimé dans un couloir conique (3). Dans le centre de cette chambre de compression est disposée une admission ou plusieurs de celles-ci pour des carburants liquides ou gazeux (4) qui au niveau central de cette pièce métallique mélange ces deux composants. Par leur pression, ils se dirigent vers la seule issue possible, c'est-à-dire la chambre de combustion (5). La deuxième prise de carburant (6) étant disponible afin d' augmenter la température de combustion et d'être en mesure de traiter les composés organiques volatils (COV). This apparatus is constituted by a metal masterpiece, under the name: compression chamber (1) having several functions: in the lower part (A) it channels the gas to be treated by means of a flame arrester (2) then this gas is slightly compressed in a conical corridor (3). In the center of this compression chamber is disposed an inlet or more thereof for liquid or gaseous fuels (4) which at the central level of this metal part mixes these two components. By their pressure, they move towards the only possible outlet, that is to say the combustion chamber (5). The second fuel intake (6) is available to increase the combustion temperature and to be able to process volatile organic compounds (VOCs).
En partie haute de la chambre de compression se situe l'élément de mise à feu Comburant/Carburant (7), fonction effectuée par une bougie de type automobile, ou par un éclateur, l'un ou l'autre étant mis en fonctionnement par un courant électrique haute tension (minimum 5.000 volts). Incluse dans la chambre de compression est disposée une sonde de température (8) ayant le rôle de détecter et d'asservir le fonctionnement de la torchère. In the upper part of the compression chamber is the firing element Fuel / Fuel (7), function performed by a car-type candle, or a spark gap, one or the other being operated by a high voltage electrical current (minimum 5,000 volts). Included in the compression chamber is a temperature sensor (8) having the role of detecting and controlling the operation of the flare.
Au dessus de cette structure d'évacuation des gaz brûlés (9) et de l'arrête-flammes (10) est disposé latéralement un conduit tubulaire (11) ayant la fonction de canaliser le gaz assaini pour en mesurer la qualité. Above this exhaust gas evacuation structure (9) and the flame arrester (10) is disposed laterally a tubular duct (11) having the function of channeling the sanitized gas to measure the quality.
Il est possible, afin d'obtenir une meilleure pureté du gaz à assainir, de disposer plusieurs arrête-flammes (12) en série sur le circuit d'évacuation des gaz traités. It is possible, in order to obtain a better purity of the gas to be sanitized, to have several flame arresters (12) in series on the evacuation circuit of the treated gases.
