摘要：框式盐析釜是化工生产过程中关键设备之一。而所谓盐析反应，一般是指溶液中加入无机盐类而使某种物质溶解度降低而析出的过程。密封装置可采用机械密封、填料密封等密封结构。加热、冷却可采用夹套、半管、盘管、米勒板等结构，加热方式有：蒸汽、电加热、导热油，以满足耐酸、耐高温、耐磨损、抗腐蚀等不同工作环境的工艺需要，而且可根据用户工艺要求进行设计、制造。搅拌器有锚式、框式、桨式、涡轮式、刮板式、组合式，转动机构可采用摆线针轮减速机、无级变速减速机或变频调速等，可满足各种物料的特殊反应要求。23602

Design of the box type salting-out kettle
Abstract：Box type salting-out kettle is one of the key equipment in the process of chemical production. The salting-out reaction, generally refers to adding inorganic salts in the solution and reduce some substance solubility and precipitation process. The sealing device can adopt mechanical seal, packing seal, seal structure. Heating, cooling the jacket, half pipe, coil, Miller plate structure, heating methods: steam, electric heating, heat conducting oil, to meet the needs of process of acid, high temperature resistant, abrasion resistance, corrosion resistance and other different working environment, but also can according to user requirements for the design, manufacture technology.. The stirrer has anchored, frame type, paddle type, turbine type, scraper type, combination type, rotary mechanism can adopt the cycloid pin wheel reducer, stepless reducer or frequency control, can meet the special requirements of the reaction of various materials.
Key Words：Pressure vessel; reactor; salting-out reaction: stirrer;
