Dryer configuration be double-tower type, drying tower and regenerator alternate work, moved in circles, and reach drying purpose.Its work
Circulation is divided into absorption and two stages of regeneration：Drying stage, drying tower pressure rise, the steam partial pressure in air also accordingly carry
Height, when by drier bed, vapor is adsorbed by drier, gradually steps up desiccant surface steam partial pressure, reaches
Balance, makes compressed air obtain drying；Regeneration stage, tower inner air pressure is set to reduce suddenly, the partial pressure of vapor similarly drops
Low, the vapor adsorbed in drier is transferred in air, is desorbed drier.Adsorption process is that desiccant surface free energy subtracts
Few process, it does not need external enwergy to promote and the spontaneous progress of energy.Regenerative process is the inverse process of adsorption process, that is, drier
The process that surface free energy recovers, and regenerative process is the process of power consumption.Heatless regenerative adsorption dryer regenerative process follows 2
Individual principle：(1) principle is regenerated completely：Adsorb half period T in be adsorbed moisture, should certain time interval T ' in completely desorption side by side
Go out the outer (T' of tower<T), and desiccant temperature will reach the initial temperature of setting before next sorption cycle starts；(2) minimum consumption
Gas principle：Under certain regeneration pressure and discharge temperature, when regeneration tail gas water content is close to saturation, regeneration gas consumption is minimum.
If there is " meromorphosis " phenomenon in regeneration stage, desiccant surface activation recovering less than original level, influence by
The outlet dew point of compressed air is handled, while accumulation of the Residual water in drier can influence its service life.Therefore it is existing
Heatless regenerative adsorption dryer in order to avoid " meromorphosis ", increase regeneration gas consumption can meet the complete of drier as far as possible
Full regeneration, this results in the consumption of regeneration gas and the energy is excessive, but if reducing regeneration gas consumption, " meromorphosis " can be serious
Influence the service efficiency of drier and the service life of drier.
