Abstract
The utility model discloses an acrylonitrile polymerization kettle with stirring and heat exchange functions, which relates to a chemical heat radiating device. The acrylonitrile polymerization kettle is composed of a sealed shell, a stirring shaft, a stirring paddle and a heat radiating water pipe, wherein the wall of the sealed shell is coated with a jacket layer, a feed opening is formed in the external upper end of the sealed shell, a discharge opening is formed in the external lower end of the sealed shell, the stirring shaft is arranged at the center axis in the sealed shell, a driving device is connected to the upper end of the stirring shaft, the stirring paddle is arranged on the stirring shaft in the sealed shell, and a water inlet pipeline and a water outlet pipeline are arranged at the center of the stirring shaft and are communicated with the heat radiating water pipe on the stirring paddle. According to the device, the stirring paddle is used for heat radiating, the heat radiating water pipe is arranged in the stirring paddle, and meanwhile, reaction heat in the jacket type reaction kettle is taken away by water flow, so that various heat radiating and cooling measures are applied to the acrylonitrile polymerization kettle disclosed by the utility model to effectively control the temperature in the reaction kettle within a required range; since the heat exchange medium is water, the application cost is reduced, the acrylonitrile polymerization reaction is safe and reliable, an accident is avoided, and the acrylonitrile polymerization kettle is convenient to popularize and use on the market.
Description
Technical field
The utility model relates to a kind of chemical industry heat abstractor, relates in particular to a kind of acrylonitrile polymerization still that stirs heat exchange.
Background technology
Acrylonitrile is a kind of colourless pungent smell liquid that has, and belongs to popular basic organic chemical industry product, is three large synthetic material---the basic and important raw materials of synthetic fibers, synthetic rubber, plastics, of many uses in organic synthesis industry and people's economic life.Inflammable, its steam and air can form explosive mixture.Chance naked light, Gao Reyi cause burning, and give off poisonous gas.Violent with oxidant, strong acid, highly basic, amine, bromine reaction.Under the high temperature of the scene of a fire, can there is polymerization exotherm, container is broken.When acrylonitrile polymerization reaction take place, will produce a large amount of reaction heat, this makes acrylonitrile be easy to occur blasting phenomena, in order to address this problem the most methods of present employing, be, in reactor, set up paddle, when reaction, by the Stirring of paddle, realize reactor is lowered the temperature, but the DeGrain of this use paddle cooling, heat dispersion is bad, can not regulate fast and effectively the temperature in reactor.
Utility model content
The utility model is intended to for the deficiency existing in background technology, and a kind of acrylonitrile polymerization still that stirs heat exchange is provided.
The acrylonitrile polymerization still of stirring heat exchange of the present utility model, to be formed by closed shell, shaft, paddle and heat dissipation pipe, on the housing wall of described closed shell, be coated with chuck layer, in closed shell outer upper ends, be provided with feeding mouth, lower end is provided with discharging opening, closed shell inside center axle place is provided with shaft, the upper end of shaft has connected drive unit, on shaft in closed shell, be provided with paddle, the center of shaft is provided with inlet pipeline and outlet pipeline, and inlet pipeline all communicates with the heat dissipation pipe on paddle with outlet pipeline.The top of chuck layer is provided with water inlet, bottom is provided with delivery port.
As further improvement of the utility model, paddle adopts the metal material of good heat conductivity to make.
The acrylonitrile polymerization still of stirring heat exchange of the present utility model, reasonable in design, when adopting paddle heat radiation, in paddle, be provided with heat dissipation pipe, adopt jacket type reactor simultaneously, flowing of water taken away the reaction heat in reactor, the utility model adopts many-sided radiating and cooling means, can more effective temperature in reactor be controlled in the scope of requirement, and heat transferring medium is water, reduced use cost, make the polymerisation of acrylonitrile more safe and reliable, avoided the generation of accident, be conducive to popularization and the use in market.
Accompanying drawing explanation
Fig. 1 is the structural representation of the acrylonitrile polymerization still of stirring heat exchange of the present utility model.
