The utility model belongs to
sulfonylurea production technical field discloses a kind of production device of
sulfonylurea, including reaction kettle main body, and the inside of reaction kettle main body has hollow interlayer;Spiral heat exchange mechanism, spiral heat exchange mechanism includes by concentric arrangement inner spiral guide vane and outer spiral
cooling pipe, and the rotation direction of inner spiral guide vane and outer spiral
cooling pipe is opposite;Dispersion mechanism, dispersion mechanism includes with the vertical and rotation installation
drive shaft of reaction kettle main body, and
drive shaft is driven by
drive motor mounted on reaction kettle main body, and three
layers of dispersion disc are installed on
drive shaft, and inner spiral guide vane is welded to the inner wall of reaction kettle main body, and the inclination angle of inner spiral guide vane is 45 °, and the plate height of inner spiral guide vane is one sixth of reaction kettle main body
diameter.The utility model not only can realize dynamic strengthening heat exchange, but also can guarantee the efficiency of
mass transfer in high
viscosity stage, while it can solve the problem of local overheating caused by sulfonation heat release.
