POSTOPEK PRIDOBIVANJA SREDSTEV ZA MELIORACIJO V OBLIKI GRANULATA ZA POŠKODOVANA ZEMLJIŠČA IN/ALI ZEMLJIŠČA S POMANKLJIVOSTMIPROCEDURE FOR THE PURCHASE OF GRANULATE RECOVERY MEDICINAL PRODUCTS FOR DAMAGED LANDS AND / OR LANDFILLS
1. PODROČJE TEHNIKE1. TECHNICAL FIELD
Ta izum pokriva postopek za pridobivanje sredstev za melioracijo v obliki granulatov za poškodovana zemljišča in/ali zemljišča s pomankljivostmi, posebno v poljedelstvu in gozdarstvu.The present invention relates to a process for the production of amelioration in the form of granules for damaged land and / or defective land, especially in agriculture and forestry.
2. TEHNIČNI PROBLEM2. TECHNICAL PROBLEM
V zadnjih letih je opaženo v povečanem obsegu poslabšanje vegetacije, posebno zdravstvena kondicija mnogih rastlin. Večji deli gozdov so zboleli.The deterioration of vegetation, especially the health status of many plants, has been observed in recent years. Large parts of the forests fell ill.
Obstojijo že večje gozdne površine v katerih drevje ne raste več, listje in iglice rumenijo in padajo, v bistvu drevje umira. Isto velja tudi za poljedelstvo.There are already large forest areas where trees no longer grow, leaves and needles turn yellow and fall, in fact the trees are dying. The same is true of agriculture.
3. STANJE TEHNIKE3. BACKGROUND OF THE INVENTION
Razlogi zaradi katerih pride do poškodb gozdov do sedaj še niso popolnoma razjasnjeni, vendar je, poleg drugega, to zaradi škodljivih primesi v atmosferi, kar povzroča zmanjšanje pH vrednosti v zemljišču in zaradi tega prihaja do nadaljnih motenj v pretoku hranljivih snovi v vegetaciji.The causes of damage to forests have not yet been fully elucidated, but, among other things, this is due to harmful impurities in the atmosphere, which causes a decrease in the pH value in the soil and consequently leads to further disturbances in the flow of nutrients in the vegetation.
V tej zvezi posebno važno vlogo igra tako imenovani kisli dež, ki obteži zemljišča s SO2 in podobnim.The so-called acid rain plays a particularly important role in this regard, and it burdens soils with SO 2 and the like.
Pretok hranljivih snovi je posebno važen pri gozdovih. Drevje preko korenin jemlje za življenje važne hranljive elemente iz zemljišča, pri čemer se en del trdno vgrajuje v novo izrastlo deblo, veje in iglice, drugi večji del pa ponovno prek vej, iglic in listov izhaja na primer z dežjem, se izpira in ponovno prehaja v zemljišče. Potem se tudi s padanjem listov, iglic, plodov, mrtvih vej, skorje itd. znatne količine hranljivih elementov znova prineso na površino zemljišča. Prej je prevladovalo mišljenje, da je na ta način enkrat za vselej poskrbljeno za oskrbo gozdov z hranljivimi elementi, danes pa se ve, da ta domneva ne velja, posebno za kraje s siromašnim ali degradiranim zemljiščem, kot tudi za kraje v katerih je pretok hrane moten, na primer nezadostni menjavi surovega humusa ali pri uporabi slame v krajih z veliko onesnaženostjo zraka.Nutrient flow is particularly important in forests. Root trees take vital nutrients from the soil through the roots, with one part firmly embedded in the newly sprouted trunk, branches and needles, and the other major part re-emerging through branches, needles and leaves, for example with rain, rinsing and re-crossing into the land. Then by dropping leaves, needles, fruits, dead branches, crusts, etc. significant quantities of nutrients are again brought to the surface of the land. Formerly, the prevailing view was that the supply of forests with nutrients was maintained once and for all, but today it is known that this assumption is not valid, especially in places with poor or degraded land, as well as in places where food flows disturbed, such as insufficient replacement of raw humus or the use of straw in areas with high air pollution.
Poleg tega na motenje preskrbe hranljivih elementov vplivajo še drugi faktorji kot so; vrsta zemljišča, dovajanje in odvajanje vode.In addition, nutritional supply disruption is influenced by other factors such as; type of land, water supply and drainage.
Dosedanji poskusi, da se kakovost zemljišča ponovno popravi, da bi se pretok hranljivih materialov ponovno vzpostavil, so v bistvu mineralno gnojenje, pri čemer se predvsem zemljišču dodajajo dušik, fosfor in kalij, vendar tudi magnezij, kalcij in mikroelementi.Previous attempts to restore the quality of the land in order to restore the flow of nutrients are essentially mineral fertilization, with nitrogen, phosphorus and potassium being added above all to the land, but also magnesium, calcium and trace elements.
Ker je potrjeno, da se z gnojenjem z apnom na zelo prekislih zemljiščih pojav pomanjkanja ponavadi ne odstrani, se je prešlo na to, da se daje apno, ki vsebuje druge hranljive snovi namesto apnene moke. Vendar se v vsakem primeru stvori gips in s tem inertna skorja, kar vpliva na pH vrednost in ne pride do trajne melioracije zemljišča.Since it has been confirmed that the occurrence of deficiency is not usually eliminated through the use of lime fertilization on very acidic soils, it has been assumed that lime containing nutrients other than lime flour is given. However, in each case gypsum is formed, and thus inert crust, which affects the pH value and does not result in permanent land reclamation.
4. OPIS REŠITVE4. DESCRIPTION OF THE SOLUTION
Naloga izuma je, da ustvari sredstvo za melioracijo poškodovanih in/ali zemljišča s pomankljivostmi, oziroma postopek za pridobitev tega sredstva s katerim se rast rastlin, posebno rast dreves lahko ne samo začasno ampak tudi trajno poboljša, pri čemer je zaželen predvsem kontinualen, časovno odvisen postopen vpliv na kvaliteto tretiranega zemljišča.It is an object of the invention to provide a means of ameliorating the damaged and / or defective land, or a process for obtaining that means by which plant growth, especially the growth of trees, can not only be temporarily improved but also permanently improved, with continuous, time-dependent gradual impact on the quality of the treated land.
V bistvu izuma je do sedaj zanemarjeno spoznanje, da je oskrbovanje navedenih zemljišč z zadostno količino magnezija bistvenega pomena za tretiranje poškodovanih in /ali zemjišč s pomankljivostmi in rastlin, ki tam rastejo.The invention is thus neglected so far that the supply of said land with a sufficient amount of magnesium is essential for the treatment of defective and / or defective land and the plants growing there.
Magnezij kot bistveni hranljivi element v rastlinski izmenjavi snovi mora opraviti cel niz važnih funkcij. Mg je sestavni del strukture klorofila, ribozoma in komponent celične membrane in kot K-faktor sodeluje v aktiviranju številnih encimov.Magnesium, as an essential nutrient in plant metabolism, must perform a number of important functions. Mg is an integral part of the structure of chlorophyll, ribosome, and cell membrane components and, as a K-factor, is involved in the activation of many enzymes.
Iz eksperimentov je znano, da mora biti količina Mg v iglicah bora ali smreke najmanj 0,03 mas. %, da bi drevesu bilo omogočeno dolgoročno preživetje (tako imenovano letalno območje).It is known from the experiments that the amount of Mg in pine or spruce needles must be at least 0.03 wt. % to allow the tree to survive long-term (the so-called flying area).
Povečanje količin odgovarjajočih hranljivih elementov v eni potezi v navedenih poznanih metod gnojenja, predstavlja samo prehodno rešitev, ker je delovanje teh gnojil samo kratkoročno. Nadalje, znana gnojila vsebujejo magnezij pretežno v obliki soli, na primer kot MgSO4.2H2O (kizerit) ali kot MgSO4.7H2O (grenka sol), vsled česa se še naprej nezaželjene aktivne snovi, kot je S vnašajo v zemljišče.Increasing the amounts of suitable nutrients in one go in the known known fertilization methods is only a transitional solution, since the operation of these fertilizers is only short-term. Furthermore, known fertilizers contain magnesium predominantly in the form of salts, for example as MgSO 4 .2H 2 O (kizerite) or as MgSO 4 .7H 2 O (bitter salt), thereby causing undesirable active substances such as S to be introduced into land.
Poleg tega je hitrost topljivosti navedenih spojin magnezija srednje specifično konstantna, kar pomeni, da se lahko doseže samo kvazi enkratno delovanje.In addition, the rate of solubility of the above magnesium compounds is of medium-specific constant, which means that only quasi-one-off action can be achieved.
Z izumom je potrjeno, da ima uporaba magnezijevega karbonata določene pomanjkljvosti. Ena od teh je to, da je toplivost karbonata relativno majhna. Da bi se ta povečala, morajo dodajati snovi z večjo površino. Material se namreč teoretično lahko izdela v odgovorjajoči obliki prahu, vendar se prah zelo težko nanese in na primer pri odmetavanju iz letala se nekontrolirano raznaša, oziroma se adsorbira suh ali v obliki suspenzije na iglicah ali listih in samo v manjših količinah dospe v zemljišče. Priprava karbonata z vezivnim sredstvom, na primer s sorel cementom omogoča izdelavo specifično za uporabo, toda to ne vodi do rešitve problema, to je, da je dodajanje Mg na takem zemljišču mogoče samo dolgoročno in znotraj relativno kratkega časovnega intervala. Poleg tega dodatno vezivno sredstvo obremenjuje samo zemljišče.The invention confirms that the use of magnesium carbonate has certain disadvantages. One of these is that the solubility of carbonate is relatively low. To increase this, they need to add substances with a larger surface area. The material can theoretically be made in a suitable powder form, but the powder is very difficult to apply and, for example, when dumped from an aircraft, it is uncontrollably distributed, or adsorbed dry or in suspension on needles or leaves and only reaches the soil in small quantities. The preparation of carbonate with a binder, for example with sorel cement, allows for use-specific production, but this does not lead to a solution to the problem, that is, the addition of Mg on such soil is only possible in the long term and within a relatively short time interval. In addition, an additional binder loads the soil itself.
Gnojenje z Mg alkalijami vodi do hitrega povečanja vsebine Mg v zemljišču, zaradi znatno večje topljivosti v primerjavi z magnezijevem karbonatom, toda tudi tu se pojavljajo znova problemi konfekcioniranja in časovne odvisnosti delovanja materiala.Fertilization with Mg alkalis leads to a rapid increase in the Mg content of the soil, due to the significantly higher solubility compared to magnesium carbonate, but again there are problems of confection and the time dependence of the material.
V izumu je predlagana splošna oblika izvajanja postopka, pri katerem se drobni magnezijev karbonat meša s drobnim magnezijevim oksidom s dodatkom vode, se granulira in potem se tako dobljene granule sušijo, da nastane melioracijsko sredstvo v obliki granulata.The invention proposes a general form of carrying out a process in which fine magnesium carbonate is mixed with fine magnesium oxide with the addition of water, granulated and then the granules thus obtained are dried to form a reclamation agent in the form of a granulate.
Presenetljivo, zmes Mg alkalij in Mg karbonatov ne vodi do fizične adicije predhodno navedenih lastnosti, prej pride do sinergijskega vzajemnega delovanja obeh komponent, kot bo spodaj bolj razjasnjeno:Surprisingly, a mixture of Mg alkali and Mg carbonates does not lead to physical addition of the above-mentioned properties, but rather the synergistic interaction of the two components occurs, as will be explained below:
Važna predpostavka za zamisel izuma je fina disperzivnost začetnih materialov. Pri tem velike površine nudijo velike reakcijske površine. Z dodatkom vode pri mešanju komponent, reagira voda z MgO in nastane magnezijev hidroksid, ki prevzema in-situ funkcijo vezila in v toku granuliranja (peletiranja) brez posebnega vezila omogoča aglomeracijo in kompaktiranje posameznih komponent zmesi.An important premise for the idea of the invention is the fine dispersion of the starting materials. In doing so, large surfaces provide large reaction surfaces. By adding water while mixing components, water reacts with MgO to produce magnesium hydroxide, which assumes the in-situ function of the binder and, in the course of granulation (pelleting), enables the agglomeration and compacting of individual components of the mixture without a special binder.
Pri postopku sušenja, ki zatem sledi in ki ga je treba izvajati v CO2 obogateni atmosferi, za kar se lahko izkoristijo odgovorjajoči plini iz peči, pride do delne karbonizacije (rekarbonizacije) stvorjenih reakcijskih komponent, tako da se v končnem, osušenem proizvodu nahajajo sledeče komponente ena poleg druge:The subsequent drying process, which must be carried out in a CO 2 enriched atmosphere, for which the corresponding gases from the furnace can be utilized, results in the partial carbonization (recarbonisation) of the generated reaction components, such that the following, in the final, dried product components side by side:
-MgCO3 (iz prvotne komponentne zmesi)-MgCO 3 (from the original component mixture)
-MgCO3 (rekarbonatizirani material)-MgCO 3 (recarbonated material)
-Mg(OH)2 (reakcijski produkt)-Mg (OH) 2 (reaction product)
-MgO (iz prvotne komponentne zmesi)-MgO (from the original component mixture)
Na osnovi povečanja razstavljivosti od - karbonata preko hidroksida do - oksida se doseže v enem sredstvu tristopenjski reakcijski mehanizem, kar pomeni, da v enem sredstvu stoje na razpolago različne komponente, ki v različnih časih razvijajo svoje delovanje na zemljišču. Presenetljivo se je pri tem pokazalo, da magnezijev karbonat, ki se nahaja v granulah in izhaja iz prvotnega materiala, ima manjšo hitrost razstapljanja kot rekarbnatiziran material, ki se nahaja še v amorfni (kar se vidi iz rentgenske preiskave) obliki, tako da se tvori in-situ četrta reakcijska stopnja, vendar v stvari izhaja samo iz dveh tekočih substanc, ki vsebujejo Mg v enem enostavnem postopku , pri čemer se dobi sredstvo v obliki granulata, ki se lahko nanaša in se zaradi velike specifične teže ne razprši in ki pri trošenju iz letala ne ostane zalepljeno na vejah, listih ali iglicah, ampak neposredno dospe na in v zemljišče.On the basis of increasing the decomposition of carbonate via hydroxide to oxide, a three - step reaction mechanism is achieved in one agent, which means that different components are available in one agent, which at different times develop their activity on the earth. Surprisingly, it has been shown that magnesium carbonate, which is present in the granules and is derived from the original material, has a lower rate of dissolution than the recarbonated material, which is still in amorphous (as seen from the X-ray) form, so that it forms in-situ fourth reaction step, but in fact only arises from two liquid substances containing Mg in one simple process, yielding an agent in the form of a granulate which can be applied and is not dispersed due to high specific gravity and which from the aircraft it does not remain stuck on branches, leaves or needles, but reaches directly into and into the ground.
Različne hitrosti topljenja posameznih komponent sredstva, peljejo do tega, da se izhajajoč iz enega delovanja do katerega pride takoj, posebno zaradi vsebnosti MgO, lahko doseže dolgoročno delovanje do deset let (pri čemer težko topen karbonat manifestira svoje delovanje).The different melting rates of the individual components of the agent lead to the fact that starting from one action that occurs immediately, especially because of the MgO content, it can achieve long-term performance of up to ten years (with the hardly soluble carbonate manifesting its action).
Samo po sebi je razumljivo, da so količine posameznih reakcijskih komponent odvisne od prvotnega razmerja zmesi magnezijev karbonat/magnezijev oksid. To razmerje mora biti med 10:1 do 2:1, pri čemer se egzaktno razmerje zmesi določi vsakič posebej v odvisnosti od kvalitete zemljišča, oziroma po željeni časovni odvisnosti delovanja.It is self-evident that the amounts of the individual reaction components depend on the original magnesium carbonate / magnesium oxide ratio. This ratio must be between 10: 1 and 2: 1, the exact ratio of the mixture being determined individually depending on the quality of the land, or according to the desired time dependence of the operation.
Bolj je material drobnejši, večja je reakcijska površina in večje skupno delovanje sredstva. Pri tem še bolj vpliva na reakcijo izhdiščnih komponent medsebojno in z vodo. Predvsem morajo biti izhodiščne snovi v frakcijah delcev manjših od 200 μιη, pri čemer je posebej ugodno, da se največji del (preko 50 mas. %) uporabi v frakciji delcev manjših od 40 gm.The finer the material, the greater the reaction surface and the greater the overall action of the agent. In doing so, it further influences the reaction of baseline components with each other and with water. In particular, starting materials in particulate fractions of less than 200 μιη should be used, and it is particularly advantageous to use the largest part (over 50% by weight) in a particle fraction of less than 40 gm.
Nadaljnja prvenstva izuma izhajajo iz vsebine ostalih patentnih zahtevkov, kot tudi iz predloge prijave.Further advantages of the invention derive from the content of the other claims as well as from the application form.
V zvezi s tem je tu nakazano, da pri potrošnji sredstva iz izuma odnosno njegovih izhodiščnih komponent, da se lahko dodajajo tudi dodatni materiali, posebej da bi se v danem slučaju omogočila še kompleksnejša melioracija zemljišča. V zvezi s tem se misli na najrazličnejše materiale: od katerih so lahko nekatere manjše količine dodatnih vezilnih sredstev, toda predvem gre za tuje, hranljive snovi, vsakič v odvisnosti od kvalitete zemljišča. Možno je tudi, da primešajo dodatne snovi, kot so zeoliti, ki aktivirajo možnost ionske izmenjave in/ali regulirajo možnost shranjevanja vode. Mogoč je tudi dodatek manjših količin poznanih gnojil, vendar je osnovna zamisel izuma omogočitev pridobivanja sredstva, ki vsebuje Mg.In this connection, it is indicated here that, when consumed, the means of the invention or its starting components, that additional materials may be added, especially in order to enable even more complex land reclamation in the given case. In this respect, a variety of materials are thought of: some of which may be smaller quantities of additional binders, but especially foreign, nutrients, each depending on the quality of the land. It is also possible to mix additional substances, such as zeolites, which activate the possibility of ion exchange and / or regulate the possibility of water storage. It is also possible to add smaller amounts of known fertilizers, but the basic idea of the invention is to provide an agent containing Mg.
Kot je že zgoraj razloženo, se lahko sredstvo razširi po zemljišču z rokami ali odgovarjajočimi vozili, lahko pa se ga trosi po gozdovih z letalom. V vsakem slučaju dodatek sredstva po izumu ne vpliva samo na korekturo pH vrednosti v odvisnosti od izbranih izhodiščnih materialov in njihovih koncentracij, ampak tudi na optimiziranje pretoka hranljivih elementov pri rastlinah, ki rastejo na zemljiščih tretiranih s tem sredstvom.As explained above, the asset can be spread over land with hands or matching vehicles, but it can be spread over forests through aircraft. In any case, the addition of the agent of the invention not only affects the pH correction depending on the starting materials selected and their concentrations, but also optimizes the flow of nutrients to the plants growing on the land treated with this agent.
