Problems solved by technology

PET bottle-grade chips must undergo crystallization before the high-temperature solid-state polycondensation reaction, and the temperature needs to rise above 100°C. Usually, a heat exchanger is used to exchange heat with water vapor, which requires high water vapor and high energy consumption. Water vapor pressure and temperature are relatively difficult to control, which can easily cause temperature fluctuations of PET bottle-grade slices and affect the quality of PET bottle-grade slices

Abstract

The invention discloses a crystallization system device of PET (Polyethylene Terephthalate) bottle grade chips. The crystallization system device comprises a crystallization device, wherein the crystallization device is provided with a feeding opening, a discharging opening, an air inlet and an air outlet; the air inlet is provided with a draught fan and a heater; the air outlet is provided with acyclone separator. The crystallization system device is reasonable in design and simple in structure; the PET bottle grade chips are crystallized through heating air, so that energy saving and stabletemperature can be realized and the crystallization degree of the slices is easy to control.

Description

Technical field [0001] The invention belongs to the field of crystallization devices, and particularly relates to a crystallization system device for PET bottle-level slices. Background technique [0002] PET bottle slices are mainly used to make packaging bottles (such as black tea, green tea, juice, Coca-Cola, Pepsi, Sprite, oil bottles, etc.). PET bottle-grade chips must undergo crystallization before the solid-phase polycondensation high-temperature reaction, and the temperature needs to rise above 100°C. Usually a heat exchanger is used to exchange heat with water vapor, which requires high corresponding water vapor, high energy consumption, and The water vapor pressure and temperature are relatively difficult to control, and it is easy to cause fluctuations in the temperature of PET bottle-level chips, which affects the quality of PET bottle-level chips. Summary of the invention [0003] The object of the present invention is to provide a crystallization system device for P...
