Abstract

本发明是一种有机多元素过磷酸钙，其原料由磷矿、赖氨酸废液(也称液肥)和硫酸组合而成。产品的制法是先将赖氨酸废液加入磷矿中制成矿浆，再用硫酸分解、化成、经熟化后即为成品。它的特点是利用赖氨酸生产过程中产生的废液来生产磷肥，不仅在磷肥中引入了氮、磷、钾、硫和腐植酸，成为多元素肥料，增加肥料品质和肥效；而且为赖氨酸生产过程中产生的废液处理开辟了一条新途径，是环境保护的一项有效措施。

Description

一种过磷酸钙肥料
本发明涉及一种有机磷肥，特别是一种有机多元素过磷酸钙肥料。
据申请人所知：目前国内大量生产的普通过磷酸钙，原料为磷矿和硫酸组合而成，其常规方法是先将磷矿磨细成矿浆，再经硫酸分解化成，经熟化后即为成品。该产品有效成份为磷酸二氢钙、磷酸氢钙，含P2O512-18％。由于产品有效养份单一、浓度低，在国外经济发达的国家该产品已被淘汰。虽然国内已有新的磷肥品种开发成功，如用稀土矿生产的稀土磷肥、用家禽粪便生产的有机磷肥等，但尚在推广运用阶段。
本发明的目的意在克服上述普通过磷酸钙有效养份单一、浓度低的不足，发明人经潜心研究，成功地研制了一种有机过磷酸钙肥料。
本发明的目的是以这样的方式来达到：原料由磷矿、赖氨酸废液(也称液肥)和硫酸组合而成。其废液是赖氨酸生产过程中产生的废液(含有机质、氨基酸、氮、磷、钾、硫等有用物质)。产品的制法是：先将赖氨酸废液加入磷矿中制成矿浆，再用硫酸分解、化成，最后经熟化后即为有机多元素过磷酸钙肥料。
本过磷酸钙肥料的原料配比按重量百分比计：磷矿石为35-65％、赖氨酸废液为12-40％、浓硫酸为20-26％。
本过磷酸钙肥料的原料配比按重量百分比计：磷矿粉为35-58％、赖氨酸废液为20-40％、浓硫酸为20-25％。
本过磷酸钙肥料中含P2O5≥12％、N1-4％、K2O0.05-0.2％、腐植酸4-16％。
本发明与普通过磷酸钙相比：其特点是用赖氨酸废液生产磷肥，不仅在磷肥中引入了氮、磷、钾、硫和腐植酸，成为多元素肥料；而且，为赖氨酸生产过程中产生的废液处理开辟了一条新渠道，是环境保护的一项有效措施。
以下结合实施例对本发明作进一步说明：
图1为本发明的生产工序流程图之一。
图2为本发明的生产工序流程图之二。
实施例一：原料配磷矿石100kg、赖氨酸废液20-100kg、浓硫酸40-60kg。
本发明产品的生产工序(参见图1)：按上述重量配料，在磷矿石中加入赖氨酸废液和水经球磨将磷矿石磨细→再补加赖氨酸废液置浆池内制成矿浆(矿浆含水量为30-35％)→加入浓硫酸经搅拌混合→化成→熟化后即为成品。其工序中的球磨、制浆、混合、化成、熟化均为现有生产普通过磷酸钙的常规方法。本成品经测试：含P2O5≥12％、N1-4％、K2O0.05-0.2％、腐植酸4-16％(测试报告待补)。
实施例二：原料配磷矿石100kg、赖氨酸废液50kg、浓硫酸50kg。本发明产品的生产工序(参见图1)同实施例一。
实施例三：原料配磷矿石100kg、赖氨酸废液100kg、浓硫酸40kg。本发明产品的生产工序(参见图1)同实施例一。
实施例四：原料配磷矿石100kg、赖氨酸废液25kg、浓硫酸60kg。本发明产品的生产工序(参见图1)同实施例一。
实施例五：原料配磷矿粉100kg、赖氨酸废液40-100kg、浓硫酸40-60kg。
本发明产品的生产工序(参见图2)：按上述重量配料，在磷矿粉中加入赖氨酸废液和水置浆池内制成矿浆(矿浆含水量为30-35％)→加入浓硫酸经搅拌混合→化成→熟化后即为成品。其工序中的制浆、混合、化成、熟化均为现有生产普通过磷酸钙的常规方法。本成品经测试：含P2O5≥12％、N1-4％、K2O0.05-0.2％、腐植酸4-16％(测试报告待补)。
实施例六：原料配磷矿粉100kg、赖氨酸废液50kg、浓硫酸50kg。本发明产品的生产工序(参见图2)同实施例五。
实施例七：原料配磷矿粉100kg、赖氨酸废液100kg、浓硫酸40kg。本发明产品的生产工序(参见图2)同实施例五。
实施例八：原料配磷矿粉100kg、赖氨酸废液40kg、浓硫酸60kg。本发明产品的生产工序(参见图2)同实施例五。
