Reactive monomer separation device

A reactive monomer separation device, comprising:

• a cylindrical column;
• a plurality of dual flow trays provided inside the cylindrical column to partition a plurality of stages;
• and
• a feed supply unit provided in one of the plurality of stages to supply a raw material including a liquid reactive monomer,
• wherein the feed supply unit includes:
• a circular feed transfer pipe provided along an inner wall of the cylindrical column,
• one or more inner pipes extending in a direction of a central axis from the circular feed transfer pipe, and
• a spray nozzle provided at each end of each of the one or more inner pipes, and
• a spray angle (θ) of the spray nozzle is equal to or less than a maximum spray angle defined by the following Equation (1):
