Description
技术领域 technical field
本实用新型涉及一种可用于易挥发物质的蒸馏分析系统，特别涉及一种高效环保全自动蒸馏系统。 The utility model relates to a distillation analysis system that can be used for volatile substances, in particular to an efficient and environment-friendly automatic distillation system.
背景技术 Background technique
传统的化学反应及蒸馏系统的主要装置为一个电加热套、一个三口蒸馏瓶和一个冷凝管等。将蒸馏瓶和冷凝管连接紧密，投入试料和消解酸后加热使反应进行，反应产生的HF、HCl、HBr等酸性气体在冷凝管中被冷却后通过吸收液收集，用于定量分析。反应完毕后等待系统自然冷却，然后拆掉整个实验装置，清洗蒸馏瓶和冷凝管等，再次组装后进行下一次实验。由于定量分析需要多次平行实验，对该系统的反复组装、拆卸、升温、冷却大大降低了工作效率，而且造成系统内部环境的不稳定，会产生诸如导管连接处的气密性差异等系统误差，影响分析结果的精密度。其次，在反应过程中仅靠高浓度的消解酸蒸发出的水蒸气难以将酸气全部驱赶到冷凝管中，在蒸馏瓶中存有残留，而且这些酸性气体沸点较高难以在冷凝管中被冷却，影响吸收液的吸收效果。如果向蒸馏瓶中加入蒸馏水产生水蒸气，则会导致消解酸稀释，达不到完全反应。还有，反应完毕后清洗蒸馏瓶和冷凝管得到的废液不能被有效的收集，排入下水道会造成环境污染。 The main devices of the traditional chemical reaction and distillation system are an electric heating jacket, a three-necked distillation flask and a condenser tube. Connect the distillation bottle and the condenser tube tightly, put in the sample and digestion acid, and then heat to make the reaction proceed. The acid gases such as HF, HCl, and HBr produced by the reaction are cooled in the condenser tube and collected by the absorption liquid for quantitative analysis. After the reaction is completed, wait for the system to cool down naturally, then disassemble the entire experimental device, clean the distillation bottle and condenser tube, etc., and then proceed to the next experiment after reassembly. Since quantitative analysis requires multiple parallel experiments, the repeated assembly, disassembly, heating, and cooling of the system greatly reduces the work efficiency, and causes the internal environment of the system to be unstable, resulting in systematic errors such as differences in the air tightness of the conduit connections. , affecting the precision of the analysis results. Secondly, in the reaction process, it is difficult to drive all the acid gas into the condenser tube only by the water vapor evaporated from the high-concentration digestion acid, and there are residues in the distillation bottle, and these acid gases have a high boiling point and are difficult to be eliminated in the condenser tube. Cooling affects the absorption effect of the absorbent. If distilled water is added to the retort to generate water vapor, the digestion acid will be diluted and complete reaction will not be achieved. In addition, the waste liquid obtained by cleaning the distillation bottle and the condenser after the reaction can not be collected effectively, and discharge into the sewer will cause environmental pollution.
