Description
Technical field
The utility model belongs to technical field of chemical, relates to a kind of polymer reactor, the reactor being particularly made up of shell-side cylinder and tube side heat exchanger tube, the polymerisation in producing in particular for PAVC.
Background technology
In traditional polymer reactor, the heat-transfer effect of reactor is poor, and in product, impurity acetaldehyde raises, thereby reactive polymeric thing is increased, and heat-transfer effect is poorer, and impurity is further increased, and has so just formed vicious circle.
In addition, polymerisation is an exothermic reaction, and reaction liberated heat is only for warm-up cycle gas, and remaining most of heat is taken away by conduction oil cooler and hybrid cooling system, has both consumed a large amount of cooling waters, causes again valuable waste naturally.
Summary of the invention
The purpose of this utility model is to provide a kind of technological requirement that can meet in polymerization production, can reduce again the novel polymeric reactor of equipment cost.
Main technical schemes of the present utility model: improved polymer reactor, comprise shell-side cylinder and tube side heat exchange tube structure, it is characterized in that along shell-side cylinder circumference, annular channel being set at the conduction oil import and export of shell-side cylinder; In shell-side cylinder in described annular channel, have some for the mobile aperture of conduction oil; In shell-side cylinder, along heat exchanger tube direction, three baffling gripper shoes are set, in the middle of middle baffling gripper shoe, have a macropore, in upper and lower baffling gripper shoe, have some apertures.
Usually, the large bore dia in described middle baffling gripper shoe is 250mm; In upper and lower baffling gripper shoe, have the aperture that 120 diameters are 10mm.
Polymer reactor of the present utility model, also comprises upper cover known in the art, conical head, upper lower flange and pad, upper lower perforated plate, heat exchanger tube, ear seat, steelframe, bed dish, pull bar and reaction gas import and export etc.
Polymer reactor of the present utility model is especially applicable to the production of PAVC product.
The improved polymer reactor of the utility model, at the import and export cylindrical shell circumference place of conduction oil, arranges annular channel structure, on loop configuration place heat exchanger cylindrical shell, open different-diameter, the aperture of varying number, makes conduction oil along the circumferential direction enter polymer reactor housing by annular channel.Along heat exchanger tube direction, three baffling gripper shoes are set at shell side, in three gripper shoes, have the different large aperture of diameter, make conduction oil produce low speed baffling and flow.
The utility model, compared with traditional polymer reactor, has following advantages:
Improvement structure of the present utility model, makes conduction oil evenly enter shell side, thereby makes shell side temperature controlled, and lifting temperature is even; In addition, in enhancing productivity, catalyst is used to greatest extent.By improved equipment structure, well control conduction oil and imported and exported the temperature difference, variations in temperature is controlled in 1%, catalyst activity improves 10%, and production capacity improves more than 30%.
