Moisture in the air is oily and hard to tell apart. After being compressed by the air compressor, the trachea is cooled, and the water and gas are mixed with oil and solid particles to condense into water droplets. PET is a water-absorbing resin, and when it encounters undried compressed air, the PET molecules absorb and stick to the water and oil on the surface of the preform. This will cause the surface of the produced PET bottle to be blurred, small water marks will appear, and the shrinkage rate will increase. And moisture, oil, solid particles, etc. will affect the power system and reduce the service life.
Therefore, it is very necessary to install a set of high-efficiency, high-quality air dryers and air filters in the production of PET. The compressed air dryer mainly removes the water vapor from the compressed air, lowers its temperature in the heat exchanger, so that most of the water vapor will condense into water droplets, and then separate it from the airflow through the separator, and finally pass through the air. The drain channel drains the compressed liquid out of the machine. If the machine is operating normally, the water vapor in the compressed air is not more than 0.59 grams per cubic meter
