摘 要:以云南省红河哈尼彝族自治州弥勒市新哨镇山兴村煤矿褐煤为原料,进行干法制备腐植酸钠产品。优选出a2层褐煤,总腐植酸含量为52.34%,pH值为4.91作为腐植酸钠生产原料。当NaOH用量为24%时,制备的腐植酸钠产品品质最佳:总腐植酸含量为39.66%,可溶性腐植酸含量为30.77%,pH值为10.86,水不溶物含量为23.24%。产品产业化选址为弥勒山兴村矿区。干法工艺具有不产生废气、废液、固体废弃物等优点,环境压力无新增。设备选型、车间布局规模及设计的工艺操作能实现年产能20000 t,设备总投资52.5万元。Dry extraction of Na-HA was conducted using lignite from Shanxing Village coal mine in Xinshao Town,Mile City,Honghe Hani Yi Autonomous Prefecture,Yunnan Province.The a2 seam lignite with the total humic acid content of 52.34%and the pH value of 4.91 was used as the raw material to produce Na-HA.The quality of the Na-HA product obtained was the best when the 24%of NaOH dosage was used,and the Na-HA product was consisted of the total humic acid content of 39.66%with the soluble humic acid content of 30.77%,the pH value of 10.86,and the water insoluble content of 23.24%.The location for product industrialization was in the Shanxing Village mining area of Mile City.The dry process had the advantages that no waste gas,liquid waste and solid waste was produced,thus there was no new environmental pressure.The equipment selection,workshop layout scale,and designed process operations could achieve the annual production capacity of 20000 t,with the total investment of 525000 yuan.
