Description

Tehnikavaldkond Technical field

Leiutis käsitleb mullaparanduspreparaati, mis sisaldab orgaanilise sõnniku segu koos põlevkivitööstuse tahke jäätmega ja/või mullaparandusainega. Lisaks käsitleb leiutis meetodit mullaparanduspreparaadi valmistamiseks. Kuna mullaparanduspreparaadi komponendid on täielikult looduslikud, võib seda liigitada orgaaniliseks väetiseks. The invention relates to a soil improvement preparation comprising a mixture of organic manure with solid waste from the oil shale industry and/or a soil improvement agent. The invention further relates to a method for preparing the soil improvement preparation. Since the components of the soil improvement preparation are completely natural, it can be classified as an organic fertilizer.

Tehnika tase State of the art

Praeguse olukorra peamiseks probleemiks on sünteetiliste väetiste kasutamise tulemusena mulla reostatus, fosforipuudus, mulla happesus (madal pH tase) ja vajalike mikroelementide, nagu mangaani, madal tase. Eriliselt on probleem mahepõllundustootmisega - sünteetilised väetised on mahepõllundustootmises keelatud ja farmid peavad kasutama põllukultuuride ringlust, et suurendada mulla toitainete taset. Järelikult on vajadus mullaparanduspreparaadi järele, mis kõrvaldab need puudused. Lisaks on leiutis heaks lahenduseks kuidas võtta kasutusele põlevkivitööstuse tahked jäätmed, mis on põlevkivi kasutavate elektrijaamade jäägiks. The main problem of the current situation is soil pollution, phosphorus deficiency, soil acidity (low pH level) and low levels of necessary microelements such as manganese as a result of the use of synthetic fertilizers. This is a particular problem with organic farming - synthetic fertilizers are prohibited in organic farming and farms must use crop rotation to increase the level of soil nutrients. Consequently, there is a need for a soil improvement preparation that eliminates these shortcomings. In addition, the invention is a good solution for how to use solid waste from the oil shale industry, which is a residue from power plants using oil shale.

Eesti patendis nr EE 03251 B1 (avaldatud 15. detsembril 1995) on avaldatud meetod põlevkivi poolkoksi ja/või põlevkivi ja settejäägi töötlemiseks väetismullaks. See meetod sisaldab põlevkivi poolkoksi ja/või põlevkivi segamist tselluloosi sisaldavate ainetega, nagu turvas. Samuti on ühes leiutise teostuses kirjeldatud põlevkivi poolkoksi segamist kanala jäätmetega. Estonian patent No. EE 03251 B1 (published on 15 December 1995) discloses a method for processing oil shale semi-coke and/or oil shale and sediment residue into a fertilizer soil. This method includes mixing oil shale semi-coke and/or oil shale with cellulose-containing substances, such as peat. Also, in one embodiment of the invention, mixing oil shale semi-coke with chicken waste is described.

Rahvusvahelises patendipublikatsioonis nr WO2005063655 (avaldatud 14. juulil 2005) on avaldatud orgaaniline mineraalväetis. Väetise mineraalsed ja orgaanilised komponendid on paigutatud ühtsesse kompositsiooni, kusjuures orgaanilised komponendid koosnevad peamiselt põlevkiviõlist ja happega töödeldud peenendatud põlevkivist ja/või orgaaniliste jäätmetega koos komposteeritud peenendatud põlevkivi poolkoksist. International Patent Publication No. WO2005063655 (published on July 14, 2005) discloses an organic mineral fertilizer. The mineral and organic components of the fertilizer are arranged in a single composition, the organic components consisting mainly of shale oil and acid-treated finely ground oil shale and/or finely ground oil shale semi-coke composted with organic waste.

Hiina patendis nr CN102701842 B (avaldatud 5. märtsil 2014) on avaldatud fosforväetise biolagundatav fermentatsioon ja selle valmistamise meetod, kusjuures toode sisaldab muuhulgas kilda- või mäestikumulda ja kuivatatud kanasõnnikut. Chinese Patent No. CN102701842 B (published on March 5, 2014) discloses a biodegradable fermentation of phosphorus fertilizer and a method for its preparation, wherein the product contains, among other things, shale or mountain soil and dried chicken manure.

Hiina patenditaotluses nr CN10554270 A (avaldatud 4. mail 2016) on avaldatud mullaparanduspreparaat, mis on valmistatud termilise töötluse abil põlevkivi poolkoksi aktiivsöest ja bioloogilistest abiainetest. Chinese patent application No. CN10554270 A (published on May 4, 2016) discloses a soil improvement preparation made from oil shale semi-coke activated carbon and biological excipients by thermal treatment.

Ükski esitatud tehnika taseme dokumentidest ei kirjelda loomuliku niiskusega orgaanilise sõnniku segu koos põlevkivituhaga, mis on saadud põletamise tulemusena, ja segu mis tahes teistest mullaparandusainetest. None of the prior art documents presented describe a mixture of organic manure with natural moisture content, with oil shale ash obtained as a result of combustion, and a mixture of any other soil improvers.

Leiutise olemus The essence of the invention

Leiutis käsitleb mullaparanduspreparaati ja meetodit selle valmistamiseks, kusjuures kõik toitained jäävad tootesse, seega võib seda toodet liigitada väetiseks. Kuna toode on täiesti looduslik, võib seda liigitada orgaaniliseks väetiseks. The invention relates to a soil improvement preparation and a method for its preparation, whereby all nutrients remain in the product, so that the product can be classified as a fertilizer. Since the product is completely natural, it can be classified as an organic fertilizer.

Toormaterjalideks, mida kasutatakse seguna koos loomuliku niiskusega orgaanilise sõnnikuga, on põlevkivituhk (mis on põlevkivi põletamise tulemus) või mullaparandusaine, nagu lubi. Põlevkivituhka ja mullaparandusainet võib samuti segada teineteisega ning siis segada orgaanilise sõnnikuga. Nendel toorainetel on molekulaarne struktuur, mis võimaldab, kui neid segada sõnnikuga, stabiliseerida sõnnikut ja siduda sõnniku niiskust. Kasutatavaks sõnnikuks on kodulinnuväljaheited. Raw materials used in a mixture with organic manure with natural moisture are oil shale ash (which is the result of burning oil shale) or a soil conditioner such as lime. Oil shale ash and soil conditioner can also be mixed with each other and then mixed with organic manure. These raw materials have a molecular structure that allows them, when mixed with manure, to stabilize the manure and bind the moisture of the manure. The manure used is poultry droppings.

Pärast segu steriliseerimist on segu vaba kõigist bakteritest ja on valmis kasutamiseks kaubandusliku orgaanilise väetisena või mullaparanduspreparaadina eriti mahepõllumajanduses. After sterilizing the mixture, it is free of all bacteria and is ready to be used as a commercial organic fertilizer or soil conditioner, especially in organic farming.

Toode parendab oluliselt mulla pH-d (tehes selle vähem happeliseks) ja lisab mulda eriti fosforit, unustamata teisi tüüpilisi komponente ja mikroelemente, mis on samuti üliolulised põllukultuuride jaoks. Toote tüüpiline NPK väärtus on järgmine: lämmastik (N) 2,5 g/t, fosfor (P) 2,5 g/t, kaalium (K) 2,5 g/t. Segu sisaldab mangaani (Mn) umbes 300 g/t ja on rikas teistest mikroelementidest ja toode takistab tõhusalt taimehaiguste levikut. Kui kasutada seda toodet, võivad põllumehed kasutada kogu oma tootmispinda kaubanduslike põllukultuuride jaoks ja see suurendab tootmispinda 50%-st kuni 100%-ni. The product significantly improves the soil pH (making it less acidic) and adds phosphorus to the soil in particular, without forgetting other typical components and trace elements that are also essential for crops. The typical NPK value of the product is as follows: Nitrogen (N) 2.5 g/t, Phosphorus (P) 2.5 g/t, Potassium (K) 2.5 g/t. The mixture contains manganese (Mn) at around 300 g/t and is rich in other trace elements and the product effectively prevents the spread of plant diseases. By using this product, farmers can use their entire production area for commercial crops and this increases the production area from 50% to 100%.

Toodet granuleeritakse või jäetakse pulbriks, nii et toote laotamist võib teostada lisades väetist seemnete istutamise ajal või laotada lihtsalt väetiselaoturiga põllule. The product is granulated or left as a powder, so that the product can be applied by adding fertilizer during seed planting or simply spread on the field with a fertilizer spreader.

Toode aitab efektiivselt kaasa fosfori taasringlusele, mis on üks enim ohustatud toormaterjalidest ja fotosünteesiks eluliselt oluline. The product effectively contributes to the recycling of phosphorus, which is one of the most endangered raw materials and vital for photosynthesis.

Leiutise eelisteostused Preferred embodiments of the invention

Leiutises esitatud mullaparanduspreparaat sisaldab segu orgaanilisest sõnnikust koos põlevkivitööstuse tahke jäätmega ja/või mullaparandusainega, kusjuures sõnnik sisaldab loomuliku niiskusega kodulinnuväljaheiteid, eelistatavalt kanaväljaheiteid. Põlevkivitööstuse tahkeks jäätmeks on põlevkivituhk, mis saadakse põlevkivi keevkihtkatlas põletamisel, ja mullaparendamisaine sisaldab lupja. The soil improvement preparation presented in the invention comprises a mixture of organic manure with solid waste from the oil shale industry and/or a soil improvement agent, wherein the manure comprises poultry droppings with natural moisture, preferably chicken droppings. The solid waste from the oil shale industry is oil shale ash, which is obtained by burning oil shale in a fluidized bed boiler, and the soil improvement agent comprises lime.

Leiutis käsitleb ka meetodit mullaparanduspreparaadi valmistamiseks, segades orgaanilise sõnniku põlevkivitööstuse tahke jäätmega ja/või mullaparendamisainega, kusjuures sõnnik sisaldab loomuliku niiskusega kodulinnuväljaheiteid, eelistatavalt kanaväljaheiteid, ja põlevkivitööstuse tahkeks jäätmeks on põlevkivituhk, mis on saadud põlevkivi keevkihtkatlas põletamisega, ja mullaparendamisaine sisaldab lupja. The invention also relates to a method for preparing a soil improvement preparation by mixing organic manure with solid waste from the oil shale industry and/or a soil improvement agent, wherein the manure comprises poultry droppings with natural moisture, preferably chicken droppings, and the solid waste from the oil shale industry is oil shale ash obtained by burning oil shale in a fluidized bed boiler, and the soil improvement agent comprises lime.

Vastavalt leiutisele saadakse põlevkivituhk keevkihtkatla põletamise protsessist temperatuurivahemikus 750 °C kuni 950 °C, eelistatavalt ligikaudu temperatuuril 900 °C. Põlevkivituhk on elektrijaamades põlemisprotsessi käigus tekkinud jääk. Põlemisprotsessi, millel on veelgi kõrgem temperatuur, tulemuseks on põlevkivituha molekulide klaasistumine, mis pidurdab väljaheidete niiskuse absorptsiooni. According to the invention, oil shale ash is obtained from a fluidized bed boiler combustion process at temperatures between 750°C and 950°C, preferably at around 900°C. Oil shale ash is a residue produced during the combustion process in power plants. The combustion process, which has even higher temperatures, results in the vitrification of oil shale ash molecules, which inhibits the absorption of moisture from the effluent.

Ühes teostuses sisaldab valmistatud orgaanilise mullaparanduspreparaadi segu orgaanilist sõnnikut vahemikus 55 kuni 65 massiprotsenti, eelistatavalt 60 massiprotsenti, ja põlevkivituhka vahemikus 45 kuni 35 massiprotsenti, eelistatavalt 40 massiprotsenti. In one embodiment, the prepared organic soil improvement mixture contains organic manure in the range of 55 to 65% by weight, preferably 60% by weight, and oil shale ash in the range of 45 to 35% by weight, preferably 40% by weight.

Järgmises teostuses sisaldab valmistatud orgaanilise mullaparanduspreparaadi segu orgaanilist sõnnikut vahemikus 55 kuni 65 massiprotsenti, eelistatavalt 60 massiprotsenti, ja lupja vahemikus 45 kuni 35massiprotsenti, eelistatavalt 40massiprotsenti. In another embodiment, the prepared organic soil improvement mixture comprises organic manure in the range of 55 to 65% by weight, preferably 60% by weight, and lime in the range of 45 to 35% by weight, preferably 40% by weight.

Veel ühes teostuses sisaldab valmistatud orgaanilise mullaparanduspreparaadi segu orgaanilist sõnnikut vahemikus 55 kuni 65 massiprotsenti, eelistatavalt 60 massiprotsenti, ja põlevkivituhka vahemikus 22,5 kuni 17,5 massiprotsenti, eelistatavalt 20 massiprotsenti, ja lupja vahemikus 22,5 kuni 17,5 massiprotsenti, eelistatavalt 20 massiprotsenti. In another embodiment, the prepared organic soil amendment mixture comprises organic manure in the range of 55 to 65% by weight, preferably 60% by weight, and oil shale ash in the range of 22.5 to 17.5% by weight, preferably 20% by weight, and lime in the range of 22.5 to 17.5% by weight, preferably 20% by weight.

Valmistatud mullaparanduspreparaadi koostisosade segamise tulemusena tekib reaktsioon, kusjuures väljaheidete niiskus seotakse seguga. Segu paigutatakse toatemperatuuril ligikaudu kolmeks nädalaks konteinerisse stabiliseerimiseks. Mixing the ingredients of the prepared soil conditioner creates a reaction, whereby the moisture from the feces is bound to the mixture. The mixture is placed in a container at room temperature for approximately three weeks to stabilize.

Mullaparanduspreparaat kui segu võib olla graanulite või pulbri kujul. Granuleerimisvõi pulbristamisprotsessi jooksul segu kuivatakse lisaks temperatuuril ligikaudu 200 °C ja tulemusena saadakse segu, millel on ligikaudu 8% niiskust. Selleks et segu oleks valmis kasutuseks kaubandusliku tootena, tuleb segu lisaks ligikaudu 70 °C temperatuuril ligikaudu ühe tunni jooksul steriliseerida. The soil conditioner as a mixture may be in the form of granules or powder. During the granulation or powdering process, the mixture is further dried at a temperature of about 200 °C, resulting in a mixture having a moisture content of about 8%. In order for the mixture to be ready for use as a commercial product, the mixture must be further sterilized at a temperature of about 70 °C for about one hour.

Käesoleva leiutise eelnevalt kirjeldatud teostusi on võimalik modifitseerida väljumata käesoleva leiutise ulatusest, mis on määratletud patendinõudlusega. The previously described embodiments of the present invention may be modified without departing from the scope of the present invention, which is defined by the claims.
