The intake air should be controlled below 0.01mg/m3; In view of the fact that oil-free air compressor can not be truly oil-free at present, in order to prevent the accumulation of trace oil in the adsorption bed (such accumulation is very fast), it is necessary to install the deoiler in the air inlet of the dryer.
The adsorption dryer should be used under the rated temperature pressure condition. When the inlet temperature is higher than or the intake pressure is lower than the rated value, the capacity correction should be carried out.
When the adsorption dryer and the piston air compressor are used, the stable pressure storage tank should be set in front to eliminate the high speed impact of the pulsating airflow on the adsorbent.
Avoid the use of "energy saving" to reduce the refuel consumption (including regenerative gas and heating power); When there is a "person who lead", adsorption dryer connection with person, as long as the license of the site should be fission installation as far as possible, in order to reduce the air pressure drop, improve person ventilation conditions and facilitate the daily maintenance;
When the gas supply is sufficient, the non-thermal regenerative dryer should be included in the first choice, and its comprehensive energy consumption will not be higher than that of heating, and its dew point is lower and more stable.
