Abstract
The utility model relates to a non-gas-consumption and low-dew-point heat recovery combined dryer which comprises a refrigerated dryer, an adsorption drier, a regeneration mechanism and a cooling circulation mechanism. By connecting the refrigerated dryer with the adsorption drier in series, compressed air is input into the refrigerated dryer when the combined dryer runs; and the low-temperature compressed air of the refrigerated dryer is input into the top end of an adsorption tower, so that partial dry air to be originally exhausted by the refrigerated dryer can perform heat exchange with a refrigerant and then is heated by an auxiliary heater. Thus, the dry air is effectively desorbed and regenerated from bottom to top through a drying agent in a regeneration tower; the compressed air with water vapor is cooled in a water-cooled refrigerator through a circulating pipeline; and finally, the compressed air is input into a heat exchanger again so as to perform low-temperature and dry circulation. As a result, the air drying effect is improved; and the extra air is not consumed during the regeneration treatment process.
