Apparatus for removing thermal stratification generated by turbulent penetration by using rotation of pipe wall

An apparatus for removing thermal stratification generated by turbulent penetration by using a rotation of a pipe wall, which is provided for removing thermal stratification formed in a branch pipe branching from a main pipe through which a high-temperature fluid flows, wherein, the branch pipe includes a first branch pipe branching from the main pipe, an elbow pipe connected to the first branch pipe to change a flow direction of the high-temperature fluid, and a second branch pipe connected to the elbow pipe, wherein the apparatus is between the elbow pipe and the second branch pipe, the apparatus comprising:

• a connection body portion including a hollow first body and a hollow second body, the first body being coupled to the elbow pipe, and the second body being spaced apart from the first body and connected to the second branch pipe;
• a hollow rotating part accommodated between the first body and the second body, the rotating part rotating around a center of the branch pipe, and
• a driving part configured to rotate the rotating part,
• wherein the rotating part has a circular shape having a certain outer diameter, and
• the first body and the second body each have a square shape, and each of the first body and the second body has a side length equal to the outer diameter of the rotating part,
• wherein edges of the first body and second body protrude outward than the rotating part, preventing the rotating part from being separated from the first body and the second body, and
• the rotating part is between the first body and the second body that face each other,
• wherein protrusions are formed to protrude and to be spaced apart from each other at certain intervals on an inner circumferential surface of the rotating part,
• wherein the protrusions are arranged at intervals of 90° on the inner circumferential surface of the rotating part,
• wherein the driving part includes:
• a pulley spaced apart from the rotating part;
• a power transmission member coupled to the pulley to surround the hollow rotating' part;
• and
• a power supply source configured to rotate the pulley.
