摘  要:
分析湛化企业集团公司过磷酸钙生产副产氟硅酸钠得率低 (每吨过磷酸钙副产 5 .86 kg氟硅酸钠 )的原因 :由于过磷酸钙混化工艺及氟吸收工艺、设备存在的问题 ,造成氟的无组织排放 ,使氟硅酸产量低、浓度波动、质量差。通过混化均衡生产 ,增加氟硅酸澄清槽 ,更新氟硅酸钠离心式过滤机和结晶槽 ,严格生产管理 ,使氟硅酸钠得率提高到 6 .82 kg/ t。按 380 kt/ a SSP计 ,可增产氟硅酸钠 36 5 t/ a,增加效益 2 0万元 /年

摘  要:
The reasons of low yield of sodium fluocilicate(5.86 kg byproduct per ton of SSP) in SSP plant of Zhanhua Enterprise Group Corp. are analyzed. Because of the problems on technology and equipment existing in the mixing section and the fluorideabsorbing section, the fluoride is non organically exhausted, the fluosilicic acid yield is low and the concentration is frequently changed. Through technique improvement, such as, stabilizing the mixing production, adding new settle tank, renewing centrifugal filter and crystallizing tank of sodium fluosilicate, and regularizing production management , the sodium fluosilicate yield is raised to 6.82 kg/t SSP, the output of sodium fluosilicate increases by 365 tons per year based on production capacity of 380 thousand tons SSP, and the profit by 200 thousand RMB Yuan per year.
