Polyester granule cutting water system

The utility model provides a polyester granule cutting water system, including water tank, plate heat exchanger, shell and tube heat exchanger and coil heat exchanger, plate heat exchanger sets up on the output pipeline of water tank for carry out the heat transfer cooling to the coolant liquid of taking out from the water tank, first heat exchanger setting is on the backflow pipeline of water tank for the heat transfer cooling is carried out to convection current return water tank's coolant liquid, coil heat exchanger sets up in the water tank. The utility model discloses a granule cutting water system compares with current granule cutting water system, does heat exchange efficiency promote 15 20%, effective heat exchange time extended to 4 hours from 40 minutes, does granule cutting water circulation temperature eventually drop to 38 from 46 DEG C 39 DEG C, can not install under the circumstances that the great merit consumes water chiller unit product that production copet etc. Expected much to the tempera
