Abstract
Description
L'invention se rapporte a une mat ère en granu I t s, en pa i I ettes ou en particules, utilisable comme substrat inerte ds3lls les sols ou plans de culture- etér i eurs ou intérieurs ou en tant que composant inerte dans un engrais ou dans toute substance destinée à modifier la nature du sol ou à lui procurer les qualités nécessaires. The invention relates to a material made of granules, in layers or in particles, usable as an inert substrate in soils or growing or indoor or indoor planes or as an inert component in a fertilizer or in any substance intended to modify the nature of the soil or to provide it with the necessary qualities.
L'invention concerne également le procédé de fabrication d'une telle matière. The invention also relates to the method of manufacturing such a material.
Certains sols, notamment ceux à caractère argileux, sc prêtent mal à ta culture en raison de leurs propriétés physiques : agglomérats imperméables ... . L'incorporation d'engrais ne suffit pas à modifier sensiblement leurs propriétés physiques pour les transformer en sols cul t i vab les. Some soils, especially those of a clayey nature, sc lend to your culture badly because of their physical properties: impermeable agglomerates .... The incorporation of fertilizers is not enough to significantly modify their physical properties to transform them into cultivated soils.
Seul un amendement important, spécifiquement dosé, pourrait procurer à ces sols quelques qualités. Only a major amendment, specifically dosed, could give these soils some qualities.
Malheureusement le prix élevé des engrais et compositions fertilisantes solides, même en faibles proportions, ne permet pas d'en faire usage de façon continue en volumes importants. Unfortunately, the high price of solid fertilizers and fertilizer compositions, even in small proportions, does not allow them to be used continuously in large volumes.
Par ail leurs, l'incorporation d'un autre type de terre dans un sol ne conduit pas forcément au résultat recherché. In addition, the incorporation of another type of soil into a soil does not necessarily lead to the desired result.
Ainsi, un sol à caractère argileux gardera pratiquement ses propriétés même si on lui apporte de la terre de culture de bonne qualité. Thus, a soil with a clay character will practically retain its properties even if it is provided with good quality soil for cultivation.
De plus, cette technique nécessite le déplacement et le brassage de volumes importants. In addition, this technique requires the displacement and mixing of large volumes.
L'invention a pour 4ut de remédier à ces inconvénients en proposant une matière inerte à utiliser directement en tant que substrat de culture ou à incorporer dans toute substance fertiligène. Elle peut également servir de composant de base à un engrais fort nécessitant une atténuation avant son incorporation dans le sol. The object of the invention is to remedy these drawbacks by proposing an inert material to be used directly as a culture substrate or to be incorporated into any fertilizing substance. It can also be used as a basic component in a strong fertilizer requiring mitigation before being incorporated into the soil.
L'invention concerne d'abord le procédé de fabrication d'une telle matière caractérisé par -l'utilisa- tion de déchets ligno-cellulosiques de toute nature, produits ou sous produits stérilisés par un traitement thermique à haute température suivi d'un traitement mécanique de réduction en particules et d'un traitement chimique dit drhydrophoî isation par action d'un sel de calcium d'acide fort puis d'un silicate soluble en contrôlant et en agissant sur la valeur du paramètre de potentiel d'hydrogène pour le maintenir à l'état final du produit entre 6 et 7. The invention firstly relates to the process for the manufacture of such a material characterized by the use of lignocellulosic waste of any kind, products or by-products sterilized by a high temperature heat treatment followed by a treatment mechanical reduction of particles and a chemical treatment known as hydrophysis by the action of a calcium salt of strong acid then of a soluble silicate by controlling and acting on the value of the parameter of hydrogen potential to maintain it in the final state of the product between 6 and 7.
On produit ainsi une matière inerte, stable dimensionnellement, dépouvue de toute tendance à dégradation par fermentation, matière qui procure aux sols des qualités supplémentaires. This produces an inert material, dimensionally stable, free from any tendency to deterioration by fermentation, a material which gives the soil additional qualities.
Par sa structure et ses qualités physiques, la matière selon l'invention favorise les trois éléments essentiels de la vie : oxygène, carbone, hydrogène. By its structure and its physical qualities, the material according to the invention promotes the three essential elements of life: oxygen, carbon, hydrogen.
Son caractère hydrophile permet la rétention d'eau par absoption, très recherchée dans l'équilibre hygrométrique des sols. Son incompressibilité augmente l'aérobie des sols. Ses qualités d'isolant thermique assurent la stabilisation des sols en température. Elle évite notamment la croûte de battance des sols argileux par suppression des tensions linéaires au retrait. Its hydrophilic nature allows water retention by absoption, much sought after in the hygrometric balance of soils. Its incompressibility increases aerobic soil. Its qualities of thermal insulation ensure the stabilization of the floors in temperature. In particular, it avoids the batting crust of clay soils by eliminating the linear shrinkage tensions.
Elle présente des propriétés actives intéressantes qui favorisent le développement végétal par
la création d'un milieu favorable au développement
bactérien;
la dispersion et la répartition appropriées de tous
les engrais solubles sans crainte d'étouffement des
racines;
l'amplification du phénomène de rhizogénèse;
le maintien de conditions optimales d'humidité et
de température dans le sol au voisinage des racines.It has interesting active properties that promote plant development by
creating an environment favorable to development
bacterial;
the appropriate dispersion and distribution of all
soluble fertilizers without fear of suffocation
roots;
amplification of the rhizogenesis phenomenon;
maintaining optimal humidity conditions and
temperature in the soil near the roots.
Son caractère parfaitement inerte et stable par rapport au milieu de culture rend son emploi exempt de réactions secondaires organiques ou chimiques. Its perfectly inert and stable character with respect to the culture medium makes its use free from organic or chemical side reactions.
En raison du traitement de stérilisation des fibres, elle n'apporte aucun élément toxique ou pathogène aux sols. Due to the fiber sterilization treatment, it does not add any toxic or pathogenic elements to the soil.
Les applications de cette matière en culture et agriculture s'avèrent multiples
- cultures en lignes
- cultures maraîchères
- cultures hors sol
- cultures en pots - art'oi' i CtJ |
- utilisation en couches de paillage et, de façon générale, elle s'applique à toute culture dif facile, par exemple en sols peu riches ou présentant des propriétés physiques peu favorables.The applications of this material in culture and agriculture are multiple
- row crops
- vegetable crops
- above-ground crops
- pot cultures - art'oi 'i CtJ |
- use in layers of mulch and, in general, it applies to any difficult crop, for example in soils which are not very rich or which have unfavorable physical properties.
Son faible prix de revient rend ltemploi de cette matière accessible à tous, aussi bien dans le cadre du jardin familial que dans la culture industrielle. Its low cost price makes the use of this material accessible to all, both in the family garden and in industrial culture.
D'autres caractéristiques techniques et avantages de l'invention sont consignés dans la description qui suit portant sur un mode de réalisation du procédé de fabrication et de la matière organique inerte selon l'invent ion. Other technical characteristics and advantages of the invention are recorded in the description which follows, relating to an embodiment of the manufacturing process and of the inert organic matter according to the invention.
Avant de débuter la description du procédé, il convient de rappeler l'étendue particulièrement vaste du champ des matières premières. II couvre toutes les matières ligno-cellulosiques : produits, déchets, sous-produits de toute nature, en particulier écorces isolées, déchets de bois avec ou sans écorce, tiges de végétaux. Before beginning the description of the process, it is necessary to recall the particularly vast extent of the field of raw materials. It covers all lignocellulosic materials: products, waste, by-products of all kinds, in particular isolated bark, wood waste with or without bark, plant stems.
Le procédé selon l'invention consiste a' faire subir aux matières, déchets ou autres, ligno-cellulosiques, préalablement broyées en morceaux, un traitement thermique par passage à la flamme sans combustion ou passage dans un flux d'air chaud porté à une température comprise entre 3000 C et 7000 C jusqu'à déshydratation. The method according to the invention consists in subjecting the materials, waste or other, lignocellulosic, previously ground into pieces, a heat treatment by passage through a flame without combustion or passage through a stream of hot air brought to a temperature between 3000 C and 7000 C until dehydration.
Ces morceaux sont réduits simultanément ou ultérieurement dans un concasseur ou broyeur en particules de granulométrie comprise entre 1 - 15 mm. These pieces are reduced simultaneously or later in a crusher or grinder into particles with a particle size between 1 - 15 mm.
On procède ensuite soit par pulvérisation, soit par immersion, à un traitement chimique par action d'une solution d'un sel de calcium d'acide fort, de préférence par du chlorure de calcium. La concentration acide de cette solution immobilise les fibres. Then, either by spraying or by immersion, a chemical treatment is carried out by the action of a solution of a calcium salt of strong acid, preferably with calcium chloride. The acid concentration of this solution immobilizes the fibers.
On fait agir ensuite un silicate soluble, par exemple une solution de silicate de potassium ou de sodium, ou le mélange des deux, en quantité variable mais en proportion de l'ordre de trois fois plus de ehlolurt de calcium, afin de maintenir le Ph entre 6 et 7 en phese finale, par exemple 6,8 pour les déchets de résineux. A soluble silicate is then made to act, for example a solution of potassium or sodium silicate, or the mixture of the two, in variable quantity but in proportion of the order of three times more calcium ehlolurt, in order to maintain the Ph between 6 and 7 in final phase, for example 6.8 for coniferous waste.
On contrôle l'évolution de la valeur du
Ph pour que sa valeur dans le produit final soit comprise entre 6 et 7.We control the evolution of the value of
Ph so that its value in the final product is between 6 and 7.
II se forme ainsi, à l'intérieur même des particules, une véritable coagulation par précipitation de silicate de calcium, sel calcaire dur et insoluble assurant à la matière une parfaite stabilité dimensionnelle et organique. There is thus formed, inside the particles, a real coagulation by precipitation of calcium silicate, hard and insoluble limestone salt ensuring the material a perfect dimensional and organic stability.
L'invention concerne également le produit obtenu par la mise en oeuvre du procédé décrit ci-dessus. The invention also relates to the product obtained by the implementation of the method described above.
La matière ainsi obtenue trouvera de multiples applications, dont celles indiquées ci-dessus, dans le domaine de la culture à petite et à grande échelle. The material thus obtained will find multiple applications, including those indicated above, in the field of small and large scale culture.
L'invention décrite ci-dessus ne saurait se limiter aux seules caractéristiques indiquées, il est bien entendu qu'elle doit s'élargir à diverses modifications simples, substitutions par des moyens équivalents et autres variantes directes sans apport inventif. The invention described above cannot be limited to the characteristics indicated, it is understood that it must extend to various simple modifications, substitutions by equivalent means and other direct variants without inventive contribution.
