Polymerization reactor for production of super absorbent polymer

A polymerization reactor for production of a super absorbent polymer, the reactor comprising:

• a composition supply part configured to supply a monomer composition solution;
• a central pipe connected to the composition supply part and located so as to correspond to a center of the water storage tank;
• a composition distribution part including a water storage tank located at a discharge port of the central pipe, a distribution pipe connected to the water storage tank, and an ultrasonic device installed inside the water storage tank;
• a conveyor belt located under the composition distribution part and on which the composition solution is dropped;
• and
• an energy supply part for supplying polymerization energy to the composition solution on the conveyor belt,
• wherein the ultrasonic device supplies bubbles to the composition solution flowing into the water storage tank,
• wherein the distribution pipe is inclined to a side wall of the water storage tank.
