1. A centrifugal dehydrator comprising:
a slurry flow tube through which a slurry, in which polymers and water are mixed, flows;
a gas flow tube through which a gas flows;
a mixture flow tube which is connected from the slurry flow tube and the gas flow tube and through which a mixture of the slurry and the gas flows;
a basket into which the mixture is injected from the mixture flow tube and which rotates to apply centrifugal force to the slurry in the mixture;
a driving part that allows the basket to rotate;
a porous plate disposed on a peripheral portion of the basket to discharge the water from the slurry to the outside of the basket; and
a pressure gauge configured to measure an internal pressure of the basket,
wherein a portion of the mixture flow tube extended to an inside of the basket includes a plurality of injection holes which are configured to inject the mixture of the slurry and the gas in one direction to the porous plate,
wherein the gas is discharged to the outside of the basket through the porous plate,
wherein the discharged gas flows to a feedback tube to flow to the gas flow tube,
wherein the feedback tube is connected to an upper portion of a housing surrounding the basket, and
wherein the pressure gauge is disposed on a rotation axis of the basket.
