Description

带机械蒸汽再压缩的强制循环连续结晶系统 Forced circulation continuous crystallization system with mechanical vapor recompression

技术领域technical field

本发明涉及一种连续结晶系统,具体为一种节能的连续结晶器,即带机械蒸汽再压缩的强制循环连续结晶系统。The invention relates to a continuous crystallization system, in particular to an energy-saving continuous crystallizer, that is, a forced circulation continuous crystallization system with mechanical steam recompression.

背景技术Background technique

传统的结晶设备是先将待结晶的溶液装入结晶器,然后使设备运行一段时间后,当溶液循环浓缩达到一定结晶量时,在打开出料泵排出晶浆,等晶浆排空后再次打开进料阀装入原液,重复上述过程。这就使生产间隙进行无法连续生产。另外,传统的结晶设备通常是将结晶器产生的二次蒸汽直接排出或是经冷凝设备冷凝后排走。这样不仅浪费了二次蒸汽的潜热,浪费了能源,还得为冷凝二次蒸汽增加一套冷凝设备,既增加了投资又不环保和经济。还有传统的结晶设备一般是在常压下蒸发的,这对有些需要低温蒸发的热敏性大的物料来说是不利的。为此,即能连续生产又可以节能而且还可以低温蒸发的结晶器成为一个研究的热点。The traditional crystallization equipment is to first put the solution to be crystallized into the crystallizer, and then run the equipment for a period of time. When the solution is concentrated and concentrated to a certain crystallization amount, turn on the discharge pump to discharge the crystal slurry, and wait for the crystal slurry to be emptied again. Open the feed valve to load the stock solution, repeat the above process. This makes continuous production impossible for production gaps. In addition, traditional crystallization equipment usually discharges the secondary steam generated by the crystallizer directly or discharges it after being condensed by a condensing device. This not only wastes the latent heat of the secondary steam and wastes energy, but also has to add a set of condensing equipment for condensing the secondary steam, which not only increases investment but is not environmentally friendly and economical. Also, traditional crystallization equipment generally evaporates under normal pressure, which is unfavorable for some heat-sensitive materials that require low-temperature evaporation. For this reason, crystallizers that can produce continuously, save energy and evaporate at low temperature have become a research hotspot.
