摘要

Closed circulation system for production of and continuously preparing a polymer solution, including a pneumatic stirrer inside and a charging hopper at a top of a drag-reducing polymer solution tank, a gas drainage pump, a submersible pump, and a compressed air pipe connected to a pneumatic diaphragm pump. A liquid inlet of the pneumatic diaphragm pump is connected to a liquid outlet of the drag-reducing polymer solution tank, and the gas drainage pump liquid discharge pipe and a liquid outlet pipe of the diaphragm pump leads to a circulation water pool; a liquid outlet of the submersible pump is connected to a liquid inlet of the drag-reducing polymer solution tank and a liquid inlet of the gas drainage pump respectively through a three way pipe. The pneumatic stirrer and pneumatic diaphragm pump operate at speeds, so the drag-reducing polymer solution is mixed uniformly and fed into the circulation water pool.
