糖厂以二效汽凝水取代原水回用锅炉是节能减排的重要措施,但含糖量过高的二效汽凝水回用锅炉后,将影响锅炉的正常使用.作者重点阐述了二效汽凝水水质与锅炉排污率的关系,推算出二效汽凝水含糖量的允许值,提出了中压锅炉回补二效汽凝水的除糖净化新工艺.为糖厂高效、安全运行锅炉提供依据. 相似文献

水处理在锅炉节能降耗方面的应用 总被引:2,自引:0,他引:2
锅炉结垢不但使传热系数降低,还容易导致发生爆管事故,同时也会产生过量排污、浪费燃料和浪费水资源等一系列问题.加强水处理可以优化水质有利于锅炉的防垢、除垢及保障安全,不但能提高锅炉热效率,还可以降低锅炉排污率,节约水资源,改善工作环境.此外,采用优化燃料、冷凝水再生技术也有助于提高锅炉热效率.运用以上方法可达到节能降耗的最终目的. 相似文献

Solid solutions of diphosphates of zinc and copper and of zinc and cobalt were synthesized from mixtures of pure diphosphates at temperatures up to 1000°C. Their X-ray diffractometry patterns varied continuously from one end member to the other. Solid solutions of orthophosphates of composition Zn3−x Cox(PO4 )2, with x = 0.4–1.6, were formed at temperatures up to 950°C; all exhibited the structure of γ-Zn3 (PO4 )2. Solid solutions of orthophosphates of composition Zn3−x Cux (PO4 )2 exhibited more-complex behavior. At 1000°C and copper contents of 20–80 mol%, a phase that is related to Cu3 (PO4 )2, termed here the "ε-phase," predominated. At 850°–950°C and in the region from 20 mol% to ∼33 mol% of copper, the solid solutions (the "η-phase") adopted the structure of graftonite. At 800°–900°C and 10–15 mol% of copper, the solid solutions exhibited a new structure (the "δ-phase"), which we found to be related to the mineral sarcopside. At temperatures 950°C, the solutions that contained 5–15 mol% of copper (the "β-phase") had the structure of β-Zn3 (PO4 )2, whereas at 800°–850°C, solutions with 5 mol% of copper (the "-phase") exhibited the structure of γ-Zn3 (PO4 )2. Attempts to synthesize Cu+ ZnPO4 and Cu+ Cu2+ Zn3 (PO4 )3 were unsuccessful. 相似文献

Gel permeation chromatographic (GPC) and thin-layer chromatographic (TLC) studies of polystyrene, polybutadienes (BR), and their copolymers (SBR) have been carried out. GPC primarily separates them on the basis of molecular size, and TLC, on the basis of composition. Methods of obtaining absolute molecular weight distributions for BR and SBR based upon variations of the Strasbourg Universal Calibration procedure are described. In particular, [η]–M relationships in both the GPC solvent (THF) and in a second solvent (toluene) were used; in addition, results of statistical mechanical calculations for \documentclass{article}\pagestyle{empty}\begin{document}$\overline {s^2 }$\end{document} (based on the assumption of negligible steric hindrance and freely rotating bonds) were applied. An experimental comparison of these methods was carried out, and use of the [η]–M relationships for both solvents was found to give satisfactory results. The predictions of the statistical theory were too low. A detailed study of polymer–solvent–gel interaction in the GPC unit was made through investigation of ternary phase equilibrium in the (polystyrene)–THF–(polymer) system. The polymers studied included BR and SBR with varying styrene contents. Experimental techniques for TLC separations of BR, SBR, and polystyrene according to the composition are described. 相似文献
