Abstract

A polymerization reactor for production of a super absorbent polymer according to the present disclosure includes: a composition supply part for supplying a monomer composition solution; a central pipe connected to the composition supply part; 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.

First claim

The invention claimed is:

1. 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.

2. The polymerization reactor according to claim 1 , wherein
the distribution pipe comprises a plurality of discharge ports configured to discharge the composition solution toward the conveyor belt, which are arranged at regular intervals along the width of the conveyor belt.

3. The polymerization reactor according to claim 2 , wherein
the discharge ports of the distribution pipe are symmetrically arranged on both sides on the basis of the water storage tank.

4. The polymerization reactor according to claim 1 , wherein
the water storage tank is configured to be filled by the composition solution, which then overflows from the tank and flows to the distribution pipe.

5. The polymerization reactor according to claim 1 , wherein the distribution pipe is located lower than an end of a side wall of the water storage tank.

6. The polymerization reactor according to claim 1 , wherein
the composition supply part further comprises a raw material supply part, a solvent supply part, and a monomer composition mixing part.

7. The polymerization reactor according to claim 1 , wherein the energy supply part is configured to supply light energy.
