The DS-R series micro heat absorption machine adopts the principle of pressure swing adsorption and regeneration cycle, and usesexternal lelectric heating) micro heating regeneration method to adsorb and dry compressed alr. The large amount ot alr discharged by theair compressor flows into the compressed air inlet pipe and enters the operating tower of the two towers through the air valve. Themoisture in it wil be absorbed by the adsorbent and dried, When the air fows to the top of the tower, all the moisture in the air is absorbedand the dew point temperature can reach -40 ', thus achieving the purpose of drying. The working process of the micro heat suctiondryer: One adsorption tower adsorbs and dries the surace under working pressure, and the other adsorption tower extracts a very smallamount of compressed air from the main pipeline, which is then depressurized and heated as regeneration gas for micro heat regenerationThe residual moisture content of the desiccant regenerated by micro heating is significantly reduced, which increases the processingcapacity of the device
