Absorption dryer is based on the principle of pressure swing adsorption, the saturated compressed air from the upstream through a certain pressure contact with the desiccant, the vast majority of water adsorption in the desiccant, dry air into the downstream work, In order to achieve the purpose of deep drying. What are the factors affecting the normal operation of the dryer?
The following factors affect the normal operation of the dryer:
1.Intake air temperature
The intake air temperature is the temperature of the compressed air entering the dryer. Under the same pressure conditions, the saturated water content increases by about 30% for each 5°C increase in temperature, which means that the humidity load entering the dryer increases by about 30%; in addition, the adsorption capacity of the adsorbent decreases with increasing temperature. Therefore, as the inlet temperature of the compressed air increases, the drying efficiency of the dryer decreases.
2.Condensed water
The compressed air discharged from the air compressor cooler is a supersaturated compressed air containing a certain amount of condensed water. In general, a small amount of condensate has little effect on the dryer.
3.Oil mist
Generally referred to as the oil-free piston air compressor (except for labyrinth, positive pressure filler protection and low-power all-oil-free machine) there is still a certain amount of oil in the exhaust, depending on its structure and specifications about 6 ~15mg/m3. Oil-injected screw air compressors with oil equivalent to an oil-free piston engine are generally considered to have oil-separator efficiency and exhaust gas temperature of 5 to 15 mg/m3, whichever is the median value of 10 mg/m3. M3.
