The invention relates to the technical field of reaction kettles, and discloses a jacket cooling and
temperature control reaction kettle, which comprises a tank body, a feed port arranged on the upper surface of the tank body, a jacket, a steam inlet
pipe, a
discharge valve and a steam outlet
pipe, the jacket is fixed on the
peripheral surface of the tank body, the steam inlet
pipe is fixed on the
peripheral surface of the jacket, the
discharge valve is fixed on the lower surface of the tank body, and the steam outlet pipe is fixed on the lower surface of the tank body. The steam outlet pipe is fixed on the lower surface of the jacket, the liquid collecting mechanism is arranged on the lower surface of the jacket, and the liquid collecting mechanism comprises a first annular groove, a first water guide plate, a vent hole, a liquid collecting frame, a liquid
discharge valve and an
exhaust valve. When the condensate water is discharged under the standard
atmospheric pressure environment, the water
attack phenomenon of the condensate water in the discharging process can be avoided, that is, the condensate water is prevented from being rapidly discharged from the liquid outlet under the action of
high pressure, and violent vibration of the reaction kettle is avoided.
