Description

Agent solide de destruction de la suie et notamment des goudrons , et son procédé de fabrication et ses utilisations Solid agent for destroying soot and especially tar, and its manufacturing process and uses
La présente invention concerne un agent solide de destruction de la suie et notamment des goudrons, ainsi que son procédé de fabrication et ses utilisations.The present invention relates to a solid agent for destroying soot and in particular tar, as well as its manufacturing process and its uses.
L'invention concerne donc le ramonage chimique des appareils de combustion et des conduits de fumée qui sont souillés par des dépôts de suie et notamment des dépôts de goudrons, dans le but d'éviter les feux de cheminée éventuels .The invention therefore relates to the chemical sweeping of combustion appliances and smoke pipes which are soiled by soot deposits and in particular tar deposits, in order to avoid possible chimney fires.
On a déjà proposé de réaliser des masses solides de destruction de la suie et des goudrons. Ainsi, le document FR-A-2 554 458 décrit un complexe combustible utilisant de faibles proportions de composés de métaux lourds . Le document FR-A-2 749 855 décrit un agent de ramonage, principalement en forme de bûche, qui renferme notamment des particules de bois, un liant tel que la cire de paraffine et un agent destructeur de suie. Cet agent de ramonage est principalement destiné à être utilisé seul, dans un foyer non actif, donc sans autre combustible en cours de combustion, c'est-à-dire de manière dite "autonome" .It has already been proposed to produce solid masses for the destruction of soot and tars. Thus, the document FR-A-2 554 458 describes a combustible complex using small proportions of heavy metal compounds. Document FR-A-2 749 855 describes a chimney sweeping agent, mainly in the form of a log, which in particular contains wood particles, a binder such as paraffin wax and a soot-destroying agent. This chimney sweep agent is mainly intended to be used alone, in a non-active fireplace, therefore without any other fuel during combustion, that is to say in a so-called "autonomous" manner.
On a toutefois constaté que, quel que soit le mérite de ce dernier agent, dans des cheminées très encrassées ou de grandes dimensions, l'effet d'une seule bûche de ramonage, utilisée d'une manière autonome, peut être insuffisant, obligeant à brûler plusieurs bûches simultanément ou à renouveler l'opération de ramonage.However, it has been found that, whatever the merit of the latter agent, in very dirty or large chimneys, the effect of a single chimney sweep log, used independently, can be insufficient, forcing to burn several logs simultaneously or to repeat the sweeping operation.
Sans vouloir se limiter à une explication particulière, on pense que, dans les conditions particulièrement difficiles évoquées ci-dessus, les goudrons ne sont pas suffisamment chauds du fait notamment de leur épaisseur pour qu'on obtienne un ramonage rapide et complet avec une seule bûche.Without wishing to be limited to a particular explanation, it is believed that, under the particularly difficult conditions mentioned above, the tars are not hot enough, in particular because of their thickness, so that rapid and complete sweeping is obtained with a single log .
Il y a donc place dans la technique pour un agent de ramonage d'activité accrue, utilisable plus particulièrement dans les cas difficiles évoqués ci-dessus.There is therefore room in the art for a chimney sweeping agent of increased activity, which can be used more particularly in the difficult cases mentioned above.
Par ailleurs, on connaît depuis longtemps l'utilisation de produits dénommés "poudres de ramonage" que l'on introduit dans des foyers actifs. Cette utilisation pose un certain nombre de problèmes en ce qui concerne sa mise en oeuvre : - difficultés d'effectuer un dosage précis de la quantité de poudre à introduire dans le foyer pour obtenir 1 ' effet maximal souhaité de destruction des suies et goudrons (le dosage est effectué généralement de fa.çon très artisanale "à la cuiller à soupe") ; - trop grande rapidité de la diffusion des fumées résultant des produits actifs, qui se traduit par une efficacité très réduite du traitement.Furthermore, it has long been known to use products called "chimney sweeping powders" which are introduced into active homes. This use poses a certain number of problems with regard to its implementation: - difficulties in carrying out a precise dosage of the quantity of powder to be introduced into the hearth to obtain the maximum desired effect of destruction of soot and tar (the dosing is generally carried out in a very traditional way "with a tablespoon"); - too rapid a diffusion of the fumes resulting from the active products, which results in a very reduced effectiveness of the treatment.
Le besoin se fait donc sentir d'apporter au consommateur un nouveau produit répondant à un double objectif : d'une part, une utilisation efficace dans des conditions difficiles (cheminées encrassées ou de grandes dimensions) ; - d'autre part, une grande précision du dosage en produits actifs nécessaires au traitement, le nouveau produit remplaçant très avantageusement les poudres de ramonage, en apportant en outre l'avantage déterminant d'une action prolongée pendant plusieurs heures des produits actifs.There is therefore a need to provide the consumer with a new product that meets a double objective: on the one hand, effective use under difficult conditions (dirty or large chimneys); - on the other hand, a high precision of the dosage of active products necessary for the treatment, the new product very advantageously replacing the sweeping powders, by additionally bringing the determining advantage of a prolonged action for several hours of the active products.
La présente invention repose donc sur un nouveau concept, celui de réaliser une masse solide, telle qu'une bûche, renfermant sous forme agrégée, et comme constituants de base, plus de 40% en poids d'agent actif sur la suie et les goudrons, le complément renfermant des déchets végétaux combustibles en particules et un agent liant.The present invention is therefore based on a new concept, that of producing a solid mass, such as a log, containing in aggregate form, and as basic constituents, more than 40% by weight of active agent on soot and tar. , the supplement containing combustible vegetable waste in particles and a binding agent.
Selon la présente invention, ledit liant est de préférence un liant organique dérivé du carbone, ce qui permet d'assurer une meilleure combustibilité de la bûche.According to the present invention, said binder is preferably an organic binder derived from carbon, which makes it possible to ensure better combustibility of the log.
L'invention concerne également l'utilisation de cette masse solide qui consiste à la placer dans un foyer actif, de préférence au contact de braises chaudes, plus particulièrement sur un lit de braises incandescentes ou proches de l'incandescence, en combustion maintenue ralentie. Grâce à la température relativement élevée des braises, la masse solide, par exemple sous forme d'une ou plusieurs bûches, va être soumise à une désagrégation/combustion/volatilisation lente, et les fumées dégagées vont traiter efficacement les goudrons de l'appareil de combustion et/ou de la cheminée, surtout si ces derniers sont de grandes dimensions ou fortement encrassés. On évitera toutefois d'opérer dans un foyer en combustion trop soutenue, afin d'éviter un entraînement trop rapide des éléments actifs de la masse solide.The invention also relates to the use of this solid mass which consists in placing it in an active hearth, preferably in contact with hot embers, more particularly on a bed of glowing embers or close to incandescence, in combustion maintained slowed down. Thanks to the relatively high temperature of the embers, the solid mass, for example in the form of one or more logs, will be subjected to a slow disintegration / combustion / volatilization, and the fumes released will effectively treat the tars of the apparatus of combustion and / or chimney, especially if these are large or very dirty. However, it should be avoided to operate in an overly sustained combustion hearth, in order to avoid too rapid entrainment of the active elements of the solid mass.
L'agent actif sur les goudrons représentera environ 41 à 90% en poids de la masse solide. Le complément sera avantageusement constitué de déchets végétaux en particules, tels que déchets de bois, et d'agent liant, de préférence combustible, par exemple de la paraffine et/ou de l'acide stéarique. Ainsi, les déchets végétaux pourront représenter 5 à 50% et le liant 5 à 50% en poids de la masse solide, le total avec l'agent actif représentant 100%. Ces valeurs sont exprimées en poids sec.The active agent on the tars will represent approximately 41 to 90% by weight of the solid mass. The complement will be advantageously consisting of vegetable waste in particles, such as wood waste, and a binding agent, preferably combustible, for example paraffin and / or stearic acid. Thus, plant waste may represent 5 to 50% and the binder 5 to 50% by weight of the solid mass, the total with the active agent representing 100%. These values are expressed in dry weight.
Des constituants secondaires peuvent être présents en plus des constituants essentiels ci-dessus, par exemple des colorants, les parfums, de l'eau d'hydratation ou d'humidité, des additifs de combustion, etc. Ces constituants secondaires pourront représenter jusqu'à 50 parties en poids pour 100 parties en poids des trois constituants de base ci-dessus. On évitera toutefois l'eau en excès de plus de 20 parties pour 100 parties (poids sec) des trois constituants de base, et l'on opérera de préférence avec des constituants aussi secs que possible, en particulier pour ce qui concerne les particules de bois.Secondary constituents may be present in addition to the above essential constituents, for example dyes, perfumes, water of hydration or moisture, combustion additives, etc. These secondary constituents may represent up to 50 parts by weight per 100 parts by weight of the three basic constituents above. However, water excess of more than 20 parts per 100 parts (dry weight) of the three basic constituents should be avoided, and the constituents should preferably be operated with as dry constituents as possible, in particular with regard to the particles of wood.
L'agent actif est avantageusement constitué par un ou plusieurs composés de métal alcalin et/ou alcalino-terreux et/ou d'ammonium et/ou d'aminé, de préférence des sels d'un ou plusieurs de ces métaux. On préférera les sels dont l'un au moins des ions constitutifs est volatil au contact de braises. Ainsi, les ions ammonium, aminé, chlorure, acétate, formiate, carbonate, sulfite et nitrate sont considérés comme relativement volatils dans le cadre de 1 ' invention et les sels qui les contiennent seront donc préférés.The active agent advantageously consists of one or more alkali and / or alkaline-earth metal and / or ammonium and / or amine compounds, preferably salts of one or more of these metals. Salts are preferred, at least one of the constituent ions of which is volatile on contact with embers. Thus, the ammonium, amine, chloride, acetate, formate, carbonate, sulfite and nitrate ions are considered to be relatively volatile within the scope of the invention and the salts which contain them will therefore be preferred.
Comme sels particulièrement utilisables, on peut citer le chlorure, l'acétate, le carbonate et/ou le nitrate de sodium, de potassium, de calcium et/ou de magnésium, ainsi que le chlorure, le phosphate, le sulfate et/ou le nitrate d'ammonium. On évitera toutefois les proportions trop élevées (par exemple 10% ou plus) de nitrate d'ammonium pour des raisons de sécurité évidentes .As particularly usable salts, mention may be made of sodium, potassium, calcium and / or magnesium chloride, acetate, carbonate and / or nitrate, as well as chloride, phosphate, sulfate and / or ammonium nitrate. Avoid the proportions too much high (e.g. 10% or more) of ammonium nitrate for obvious safety reasons.
Avantageusement au moins 50% des sels utilisés seront des sels ayant un ion volatil.Advantageously, at least 50% of the salts used will be salts having a volatile ion.
Pour agréger ensemble les divers constituants, on peut les comprimer à froid, par exemple dans une presse, le liant étant alors, comme les autres constituants, sous forme de particules solides. On préfère toutefois utiliser le liant sous forme fondue ou dissoute dans un solvant qu'on pourra éliminer ensuite, les autres constituants étant mis en oeuvre à l'état solide.To aggregate the various constituents together, they can be cold pressed, for example in a press, the binder then being, like the other constituents, in the form of solid particles. However, it is preferred to use the binder in molten form or dissolved in a solvent which can then be removed, the other constituents being used in the solid state.
Ainsi, la cire de paraffine et l'acide stéarique pourront avantageusement être utilisés à l'état fondu. On pourra alors opérer à chaud dans un moule.Thus, paraffin wax and stearic acid can advantageously be used in the molten state. We can then operate hot in a mold.
On donne ci-après des exemples, non limitatifs de l'invention, que l'on peut réaliser pour fabriquer des masses solides, par exemple des bûches, selon l'invention :The following are nonlimiting examples of the invention which can be produced for manufacturing solid masses, for example logs, according to the invention:
Bûche n° 1 (en poids sec) : 15% de chlorure de sodium, 25% de chlorure d'ammonium, 5% de nitrate de sodium, 5% de nitrate d'ammonium, 30% de paraffine et 20% de sciure de bois. Le mélange se fait à chaud avec la paraffine fondue, dans un moule, avec refroidissement ultérieur et démoulage. Poids unitaire d'un bûche : 1,5 kg.Log n ° 1 (dry weight): 15% sodium chloride, 25% ammonium chloride, 5% sodium nitrate, 5% ammonium nitrate, 30% paraffin and 20% sawdust wood. The mixing is done hot with the molten paraffin, in a mold, with subsequent cooling and demolding. Unit weight of a log: 1.5 kg.
Bûche n° 2 (en poids sec) : 20% de sulfate d'ammonium, 20% de chlorure de sodium, 10% de chlorure de calcium, 20% de paraffine (ou d'acide stéarique) et 30% de sciure de bois. Préparation à chaud comme ci-dessus. Poids unitaire d' une bûche : 1,25 kg. .he n° 3 (en poids sec) : 10% de phosphate .uni, 20% de chlorure d'ammonium, 12% de sulfate -um, 5% de nitrate d'ammonium, 5% d'acétate -um, 24% de sciure de bois et 24% de paraffine. :ion à froid dans une presse. Poids unitaire d'uneLog # 2 (dry weight): 20% ammonium sulfate, 20% sodium chloride, 10% calcium chloride, 20% paraffin (or stearic acid) and 30% sawdust . Hot preparation as above. Unit weight of a log: 1.25 kg. .he n ° 3 (by dry weight): 10% phosphate .uni, 20% ammonium chloride, 12% sulfate -um, 5% ammonium nitrate, 5% acetate -um, 24 % sawdust and 24% paraffin. : cold ion in a press. Unit weight of a
Les dimensions de particules de matière végétale sont par exemple dans la plage de 0,1 mm à 10 mm, de même que celles des particules de liant si celui-ci est utilisé à l'état solide, comme par exemple avec la cire de paraffine.The dimensions of particles of plant material are for example in the range of 0.1 mm to 10 mm, as are those of binder particles if the latter is used in the solid state, such as for example with paraffin wax .
Les sels sont également avantageusement utilisés à l'état solide cristallisé ou non. Pour l'utilisation, on opère dans un foyer préalablement chauffé, conservant un lit de braises, et on pose la masse solide, par exemple une bûche selon l'invention, sur ces braises . On peut avoir avantage à réduire le tirage pour éviter une combustion vive avec fortes flammes . La masse solide va peu à peu se désagréger en libérant les matières actives qui agissent sur les goudrons, lesquels vont se désagréger et/ou être rendus inactifs ou peu actifs vis-à- vis d'une inflammation éventuelle.The salts are also advantageously used in the solid state, crystallized or not. For use, one operates in a previously heated hearth, retaining a bed of embers, and the solid mass is placed, for example a log according to the invention, on these embers. It may be advantageous to reduce the draft to avoid lively combustion with strong flames. The solid mass will gradually disintegrate by releasing the active materials which act on the tars, which will disintegrate and / or be made inactive or not very active with respect to possible inflammation.
On a réalisé une bûche selon l'invention dont le poids total était de 1,2 kg, cette bûche comportait 500 g de produits actifs tels que définis ci-dessus, 280 g de sciure de bois et 420 g de paraffine. Cette bûche a été placée sur un foyer de braises. Elle a commencé à brûler et la combustion s'est poursuivie pendant environ 1 heure, en dégageant sous forme de fumées les produits actifs contenus dans la bûche. Après la fin de la combustion, l'émission des fumées issues des produits actifs s'est poursuivie, sous l'effet de la chaleur dégagée par le lit de braises, pendant une durée d'environ 3 heures. A l'issue de cette période de temps, la bûche était réduite en fines poussières, ayant ainsi diffusé la totalité de ses produits actifs. Environ huit jours plus tard, on a constaté une désagrégation totale des particules de matières carbonées (suies et goudrons) qui étaient présentes dans le conduit de cheminée, ces particules réduites à l'état de poudre tombant dans le foyer en débarrassant le conduit de cheminée. Ces essais démontrent le caractère efficace des bûches selon l'invention pour éliminer les suies se déposant dans les conduits de cheminée, permettant ainsi d'éviter d'éventuels feux de cheminée . A log according to the invention was produced, the total weight of which was 1.2 kg, this log included 500 g of active products as defined above, 280 g of sawdust and 420 g of paraffin. This log was placed on a hearth of embers. It started to burn and the combustion continued for about 1 hour, releasing the active products contained in the log in the form of smoke. After the end of combustion, the emission of fumes from the active products continued, under the effect of the heat given off by the ember bed, for a period of approximately 3 hours. At the end of this period of time, the log was reduced to fine dust, thus having released all of its active products. About eight days later, there was a total disintegration of the particles of carbonaceous materials (soot and tar) which were present in the chimney flue, these particles reduced to the state of powder falling in the hearth by removing the chimney flue . These tests demonstrate the effectiveness of the logs according to the invention in eliminating the soot depositing in the chimney flues, thus making it possible to avoid possible chimney fires.
