    • The invention relates to a novel process for the preparation of fertilizers, a so-called multiple-suspension process, according to which two or more raw-material suspensions of different compositions are prepared in separate reactors or reactor systems coupled in parallel. These raw-material suspensions are fed into a granulator separately or combined together immediately before the granulation, and thus the mutual reactions of the raw-materials fed into the different suspensions, and consequently also the salt composition of the product, will be different from those obtained when the same product is prepared by the normal single-suspension process.
    • 本发明涉及一种用于制备肥料的新方法,即所谓的多悬浮方法,根据该方法,在分开的反应器或并联的反应器系统中制备两种或更多种不同组成的原料悬浮液。 这些原料悬浮液在造粒前立即单独进料到造粒机中或组合在一起,因此进料到不同悬浮液中的原料的相互反应以及因此产物的盐组成将不同于那些 当通过正常单悬浮法制备相同的产品时获得。

    • The invention is directed to a process for enhancing the plant nutrient value of relatively low analysis organic waste material ( e.g. sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor or tubular reactor to form a melt; spraying the melt onto a recycling bed of fines in a granulator and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles to form an enhanced plant nutrient value composition ( e.g. a fertilizer or soil conditioner having a greater NPK value than the original relatively low analysis organic waste material). The process further includes drawing off the fumes from the granulator, passing them through a dryer with the granulated particles, and subsequently oxidizing the fumes to eliminate volatile organic compounds and/or gaseous hydrocarbon pollutants by converting such into carbon dioxide and water vapor.
    • 本发明涉及一种用于增强相对低分析的有机废物(例如污水污泥)的植物营养价值的方法,包括在管交叉反应器或管式反应器中用酸和碱处理废料以形成熔体; 在造粒机中将熔体喷射到细粉的再循环床上,并将其作为蒸汽从包含在熔体中的水闪烁; 在造粒机中将熔体滚动到再循环的细颗粒上以形成造粒颗粒; 并干燥这些造粒颗粒以形成增强的植物营养价值组合物(例如具有比原始相对较低分析的有机废物材料更大的NPK值的肥料或土壤调理剂)。 该方法还包括从成粒机中除去烟雾,将其通过具有造粒颗粒的干燥器,随后通过将其转化为二氧化碳和水蒸气来氧化烟雾以消除挥发性有机化合物和/或气态烃污染物。

    • In a process for manufacturing pelletized materials for use in chemical reactions in industry or agriculture, powdered alkaline compounds are pelletized with hydroxides of substances with widely differing solubility products. In a first stage, a small quantity of pelletizing water is added to form seeds 0.05 to 0.15 mm in size which combine to form pellets on addition of more pelletizing water. The quantity of pelletizing water added to the material in this first stage is sufficient to hydrate it but not appreciably greater. After seed formation begins, no more water is added until the raw material is completely hydrated and thereafter only the quantity of pelletizing water necessary to continue seed formation is added. To manufacture pellets for removing nitrogenous impurities, together with phosphorous-containing impurities and possibly heavy metals, the active substances used are hydrogen phosphates or phosphates of a cation of the second maingroup and sub-groups of the periodic system.
    • 在制造用于工业或农业化学反应的造粒材料的方法中,粉状碱性化合物用具有差别很大的溶解度产物的物质的氢氧化物造粒。 在第一阶段,加入少量造粒水以形成尺寸为0.05至0.15mm的种子,通过添加更多的造粒水而结合形成粒料。 在第一阶段添加到材料中的造粒水的量足以使其水合,但不明显更大。 种子开始形成后,不再加水,直到原料完全水合,然后只加入继续种子形成所需的造粒水的量。 为了制造用于除去含氮杂质以及含磷杂质和可能的重金属的粒料,使用的活性物质是第二组和周期系统的亚组的阳离子的磷酸氢盐或磷酸盐。
