耐负压钢衬四氟反应罐 Negative pressure resistant steel lined reaction vessel tetrafluoro
本实用新型涉及一种耐负压钢衬四氟反应罐，用于化学工程中完成化工物料的反应、聚合、合成、氯化等过程的化工防腐设备，属于石油化工设备本实用新型作出以前，在已有技术中，反应罐通常是采用二对主法兰、罐盖、罐体、夹套体、搅拌器、减速机所组成。 The present invention relates to a negative pressure resistant steel lined tetrafluoride reaction tank for completion of the reaction in the chemical engineering chemical materials, polymeric, synthetic chemical preservative equipment, chloride process, petrochemical equipment belonging to the present invention before, in the prior art, the reaction can usually using two main flanges, can lid, the can body, the body jacket, a stirrer, a reducer composed. 罐盖与罐体、罐体与罐底分别采用各一对主法兰连接，搅拌器安装在罐体内，减速机通过轴连接搅拌器，夹套体焊接在罐体上。 Can lid and can body, the can body and bottom respectively in each of the pair of main flange connection, a stirrer installed in the tank, a stirrer is connected through the reduction gear shaft, welded jacketed tank. 由于采用两对法兰连接限制了夹套体的安装位置，影响了夹套件的加热功能。 Since the two pairs of flange limits the mounting position of the jacket body, the influence of the heating function clamp kit. 该种结构直接在罐体内壁空套四氟衬里，罐壁与四氟衬套之间存在1-3mm不等的间隙，自然形成了中空夹层，当反应罐在高温、负压的工况下，夹层中空气聚然膨胀，对四氟衬里施加了外压，同时又承受罐内的负压，四氟衬里在双重压力下，失稳而产生永久鼓包变形。 This kind of unequal 1-3mm gap structure exists directly between the tank wall liner idler tetrafluoroethylene, tetrafluoroethylene liner and the tank wall, forming a natural hollow sandwich, when the reaction temperature in the tank, the negative pressure conditions , air sandwich then expanded polyethylene, the lining of tetrafluoroethylene external pressure is applied while subjected to a negative pressure tank, dual pressure tetrafluoroethylene liner, instability and permanent deformation of the bulge. 在实际使用中，采用在罐体外设置平衡管路，将四氟衬套夹层与反应罐本身的真空系统连通，并与反应罐真空系统启动时，四氟衬套的夹层中的空气同时被减弱，直到与罐内真空度一致，虽然从理论上解决了四氟衬里的真空均衡问题，但是，还是不能彻底解决。 In actual use, the use of balanced line disposed outside the tank, communicating with the reaction tank tetrafluoroethylene bushing interlayer vacuum system itself, starting with the reaction tank and the vacuum system, tetrafluoroethylene bushing interlayer air is simultaneously attenuated until the tank is consistent with the degree of vacuum, vacuum solves the problem of balancing the lining of tetrafluoroethylene in theory, but still not completely resolved. 因为四氟衬里变形鼓包的因素是综合的，其中有四氟材料自重、物料因搅拌旋转而产生的边界应力，四氟材料的线膨胀应力等因素，忽视了这些附加应力而单纯地解决真空均衡问题，所以四氟衬里鼓包变形无法得到彻底解决。 Because tetrafluoroethylene modification factor drum liner bag is integrated, wherein the material has a weight of tetrafluoroethylene, the material boundary stresses factors generated by rotation of the stirring, the linear expansion stress of PTFE material or the like, ignoring these additional stress and simple solution to the vacuum equalization problem, so tetrafluoroethylene lining bulge deformation can not be completely resolved.
本实用新型的目的在于克服上述不足之处，从而提供一种能在高温，负压工况下安全运行，罐体内四氟衬里不易产生鼓包变形，减少维修换罐次数，使用寿命长的耐负压钢衬四氟反应罐。 The present invention aims to overcome the above shortcomings, thereby to provide a high temperature, vacuum conditions safe operation, easy to produce liner tetrafluoroethylene tank body bulge deformation, change-can reduce the number of maintenance, long life negative resistance tetrafluoroethylene steel lined pressure reactor tank.
