Description
Išradimas priklauso trąšų pramonei ir gali būti naudojamas birioms sudėtinėms azoto, fosforo, kalio trąšoms (NPK) su antrinėmis augalų maisto medžiagomis ir mikroelementais gaminti.The invention relates to the fertilizer industry and can be used to produce bulk compound nitrogen, phosphorus, potassium fertilizers (NPK) with secondary plant nutrients and trace elements.
Yra žinomas sudėtinių trąšų gamybos būdas, kai trąšas gamina iš atskirų biriųjų trąšų jas sumaišant, sudrėkinant vandeniu ir/arba vandens garais bei pridedant susmulkinto molio (US patentas 5749936, prioritetas nuo 1996-06-07, paskelbtas 1998 m.). Gaminant šiuo būdu padidėja trąšų prekinės frakcijos išeiga, pagerėja produkto kokybė, tačiau turi būti paruošta speciali molio suspensija, o molio, kaip balasto koncentracija iki 5 masės procentų sumažina maisto medžiagų kiekį trąšose.There is a known method of producing compound fertilizers, wherein the fertilizer is produced from a single bulk fertilizer by mixing, moistening with water and / or water vapor and adding crushed clay (U.S. Pat. No. 5,794,936, priority issued June 7, 1996, published 1998). Production in this way increases the yield of the fertilizer commercial fraction, improves the quality of the product, but a special clay suspension must be prepared and the concentration of clay as ballast reduces the nutrient content of the fertilizer by up to 5%.
Artimiausias žinomas techninis sprendimas - sudėtinių trąšų gamybos būdas, kai biriųjų trąšų komponentus sumaišo su mineralinių trąšų ir amoniako sąveikos produktu granuliatoriuje, po to mišinį granuliuoja, džiovina, frakcionuoja (LT patentas 4720, prioritetas nuo 1999-11-29, paskelbtas 2000 m.). Šio būdo trūkumas yra tai, kad azoto koncentracija produkte yra nepakankamai didelė, grąžinamos perdirbimui smulkios frakcijos kiekis siekia 30 - 35 masės procentus, todėl mažėja granuliavimo įrenginio našumas.The closest known technical solution is to form a compound fertilizer by mixing the bulk fertilizer components with a mineral fertilizer-ammonia interaction product in a granulator, then granulating, drying, fractionating the mixture (LT patent 4720, priority 29-11/1999, published 2000). . The disadvantage of this method is that the concentration of nitrogen in the product is not high enough, the amount of fine fraction returned to the processing is 30-35% by weight, which reduces the efficiency of the pelletizer.
Patentuojamas biriųjų sudėtinių trąšų gamybos būdas, kai birius trąšų komponentus nuo 1 iki 10 min. maišo su drėgnais komponentais, gautais iš maišytuvo apatinėje dalyje įtaisyto vamzdinio reaktoriaus, kuriame šarminius trąšų komponentus neutralizavo mineralinėmis rūgštimis, pakelia mišinio temperatūrą ne daugiau, kaip iki 140 °C, granuliuoja, apipurškiant rūgštintu vandeniu ir/arba pašildant vandens garais, džiovina, frakcionuoja, smulkiąją granuliuoto produkto dalį grąžina į maišytuvą. Vamzdiniame reaktoriuje sumaišius šarminį komponentą su rūgštiniu komponentu vyksta egzoterminė cheminė sąveika. Šarminį komponentą sudaro amoniako vandeniniai tirpalai, kuriuose yra amonio nitrato, karbamido, amonio sulfato, kalcio nitrato, magnio nitrato arba jų mišinių, kalio šarmo ar kalio druskų arba jų mišinių. Rūgštinį komponentą sudaro azoto, fosforo ar sieros rūgštys. Šarminio ir rūgštinio komponentų molinis santykis yra NH3: H3PO4 =1-3:1, arba NH3 : H2SO4 = 0,9-2 : 1, arba NH3 : HNO3 = 0,9-1 : 1. Visų komponentų kiekius ir santykius parenka taip, kad granuliuotame produkte azoto kiekis būtų nuo 5 iki 25, o sieros būtų iki 15 masės procentų. Gali į birius trąšų komponentus įmaišyti kalcio, magnio, boro mineralų ar jų mišinių.Patented method of producing bulk compound fertilizers, where bulk fertilizer components are used for 1 to 10 minutes. mixing the wet components from a tubular reactor at the bottom of the mixer in which the alkaline fertilizer components have been neutralized with mineral acids, raising the temperature of the mixture to not more than 140 ° C, granulating by spraying with acidified water and / or steam drying, fractionation, returns a small portion of the granular product to the mixer. After mixing the alkaline component with the acidic component in the tubular reactor, an exothermic chemical interaction occurs. The alkaline component consists of aqueous ammonia solutions containing ammonium nitrate, urea, ammonium sulfate, calcium nitrate, magnesium nitrate or mixtures thereof, potassium alkali or potassium salts or mixtures thereof. The acidic component consists of nitric, phosphoric or sulfuric acids. Alkaline and acid components in a molar ratio of NH3: H3PO4 = 1 to 3: 1, NH 3 or H 2 SO 4 = 0.9 to 2: 1, or NH 3: HNO 3 = 0.9 to 1: 1. The total the amounts and ratios of the components are selected such that the granular product contains 5 to 25 percent nitrogen by weight and 15 percent sulfur by weight. May be mixed with calcium, magnesium, boron minerals or mixtures thereof in bulk fertilizer components.
