The molecular sieve of purification system has strong water absorption, but the water absorption capacity is limited to a certain extent. In order to prevent the molecular sieve from entering water during operation, the following points should be paid attention to:
The air cooling tower should be operated according to the regulations, and the gas should be introduced first, and then after the pressure rises and stabilizes;
The air volume should not be increased or decreased suddenly;
Maintain the water level of the air cooling tower, the water spray volume should not be too large, the water quality should meet the requirements, reduce the inlet temperature, and reduce the scale.
