4·3 不分离法硝酸磷肥流程简述磨细到0.175mm(80目)的磷矿粉从贮仓中用斗提机(见图4)、称量皮带称量后送酸解槽内,用硝酸贮槽中经酸泵打来并经计量的稀硝酸分解,酸解槽2台串联,酸解时间约1h,酸解温度为60℃。在酸解槽内除SiO2外磷矿全部被硝酸分解为磷酸、硝酸钙、硝酸镁等;
4.3 Non-separation of nitrophosphate fertilizer process outlined ground to 0.175mm (80 mesh) of phosphate rock powder from the silo bucket machine (see Figure 4), weighed belt weighing acid tank after the transfer, Acid tanker with nitric acid storage tank and the measurement of dilute nitric acid decomposition, acid hydrolysis tank 2 in series, the acid hydrolysis time of about 1h, acid hydrolysis temperature of 60 ℃. In the acid hydrolysis tank in addition to SiO2 all phosphate rock is decomposed by nitric acid phosphoric acid, calcium nitrate, magnesium nitrate, etc .;
