| 摘要：本设计涉及的搅拌设备是立式磁力驱动搅拌反应釜的机械设计，釜的结构采用夹套式。内筒介质为三戊酮、钯碳、氢气，设计压力为4.0MPa；夹套内介质为导热油，设计压力为0.8MPa，操作时夹套内的导热油加热内筒的物料；盘管内的介质为冷却水，设计压力为0.8MPa，操作时盘管内的冷却水冷却内筒的物料。设计方法采用压力容器的常规设计方法，按照GB150-2011《钢制压力容器》等技术法规执行，设计内容主要包括设计方案的选择、釜体（内筒和夹套）强度及结构设计、搅拌装置设计、传热装置设计、传动装置设计以及反应釜其他零部件设计等。其设计计算结果准确，与工程实际聚合釜相符；图纸符合国家机械制图标准要求，结构简单、合理，优于现场实际设备。搅拌器在原设计的基础上改为立式创新型叉叶搅拌器，釜内物料混合充分、均匀，搅拌效果满足了生产要求。本设备混合性能好、能耗低、结构简单、紧凑，占用空间及作业面积小、操作文修方便、易于使物料形成轴向流型并在彼此之间相互分散，能增大不同物相间的接触面积，大大加快传热和传质过程。因此，该浆式搅拌反应釜应用前景广阔。6857 关键词：反应釜；磁力驱动；搅拌设备；传热装置 Design of V=2m3 Magnetic Drive Reactor Abstract : Magnetic Drive Reactors are one kind of important vessels in chemical production. The reaction mechanism in it is complicated. Because of multiple controlled objects and big time-variant，non-linear，time-delay，classical control theory and optimal control of modern control theory are not fit for the control of reactors. The analysis of the reactors heat transfer characteristics， and the transfer function of cooling mixtures flux to the temperature in reactors are concluded in the paper. Intelligent control system of two-part control according to error range is designed also. Adaptive fuzzy-control based on modified rule and incomplete differential PID-control are adapted in the system. The analysis process and control algorithm are described in detail. On the basis of this，intelligent controller based on series of MCS-51 single-chip computer is designed，and popular serial bus------I~2C bus and 1-wire bus are used in this paper， which constitute the system of multiple points temperature measurement. Port circuits of single-chip computer and software program are designed in the paper，too. By controlling the executive device and condition parameters of the reactor， the control of temperature and its grade realized. The equipment is about the design of demulsified polymerize，which is used in medical，the structure of polymerize is jacket style，the media of boiler is ethylene oxide and propylene oxide， the designed pressure is 4.0MPa，the media of the jacket is water， the designed pressure is 0.8MPa; the main material is Q345R. The water of jacket cools the material of boiler. Designed methods is common， and according to GB150-2011《steel pressure vessels》，the major designed content included the choice of designed method，the design of cauldron body’s （including boiler inner and jacket） strength and structural，design of Mixing device、Heat transfer device、Actuator and other parts.
