Before the molecular sieve purifier, in order to reduce the temperature of the processed air, the first to enter the air cooling tower cooling. In the air-cooled tower air from the bottom and into the tower from the top of the lead, into the molecular sieve purifier, water from the top of the tower spray and air contact, mixing and cooling the air, air-cooled tower is equipped with a number of through the flow of the tower plate or filler, to increase the contact area. In order to water separation at the top of the tower with a water trap, when the air-cooled tower in the air flow rate is too fast, too much water or spray water is too large, the water level automatic adjustment fails, it will cause the molecular sieve purifier into the water accident.
Water inlet will have the following phenomena: molecular sieve pressure fluctuates high and low, the resistance of the adsorber rises, and the temperature curve changes after heating and cold blowing. The most obvious is the temperature drop after cold blowing and the appearance of a flat head peak. The longer the distance of the curve of the flat head wind, the more water is indicated to be fed into the molecular sieve.
How to prevent the molecular sieve purification system from water intake: the air cooling tower should be operated according to the protocol, first pass into the air, to be stable after the pressure rises; can not suddenly increase or decrease the amount of air; maintain the water level of the air cooling tower; the water spray volume can not be too large; the water quality should be up to the requirements to reduce the temperature of the water intake, and to reduce the scale.
