In general, as long as the air precooling system is normal, the temperature of air entering the purifier will not change, and the temperature of air leaving the adsorber is slightly higher than the inlet temperature due to the influence of adsorption and heat release.
The difference of air inlet and outlet temperature is related to the air inlet temperature. Because the higher the temperature of the air inlet is, the greater the saturated moisture content in the air is, the higher the removal load of the adsorber is, the greater the adsorption heat generated, and the temperature difference will increase accordingly. When the air inlet temperature is 10 ℃, the temperature rise is about 4 ℃. At the beginning of switching, there is a large temperature difference between the inlet and outlet, even up to 20 ℃. This is because the process of switching the adsorber to charging is a pressure boosting process. The adsorption capacity of the molecular sieve increases. During the charging process, some molecules (including oxygen and nitrogen molecules) are also adsorbed, and the corresponding adsorption heat is carried out by air when the adsorber is switched to use. In addition, when the adsorber was first used, the adsorption capacity of molecular sieve was large, so the temperature increased significantly. If the outlet temperature of the purifier rises suddenly during use, it means that the air has brought the water in the air cooling tower into the adsorber, which should be handled urgently.
DEAR Air Branch is committed to building a complete set of high-quality air separation equipment with advanced technology, reliable quality and high cost performance.
