On this basis, be equiped with control valve between rearmounted refrigerant condenser and the runner treatment region, the pipeline between control valve and rearmounted refrigerant condenser is provided with collateral branch's air intake, and is provided with control valve.Control valve, its function are to regulate the air capacity of processing by adsorption runner; Collateral branch's air intake needs the space of dried material to be connected with depositing, and the purpose that collateral branch's air intake is set in this device is to ensure enough air streams to put refrigerant condenser later, makes the cold-producing medium that flows in rearmounted refrigerant condenser sufficiently cooled.Control valve, control bypass air amount.

Further, refrigeration system is two covers, the air a that is in the dried material space passes through pipeline sequentially through I level refrigerating evaporator, II level refrigerating evaporator, runner treatment region, the rearmounted refrigerant condenser of II level, the rearmounted refrigerant condenser of I level and processing blower fan, flow back to again the dried material space, atmosphere c passes through pipeline sequentially through the preposition refrigerant condenser of I level, the preposition refrigerant condenser of II level, rotary wheel regeneration district and regeneration blower fan, again discharged to atmosphere.Two cover refrigeration systems can independently realize start and out of service, also can adopt different cold-producing medium models.

The utility model refrigeration system and adsorption and dehumidification runner system combination operation, the energy that the adsorption and dehumidification rotary wheel regeneration needs obtains from the condenser of refrigeration system, compare with common steam compression heat pump drying machine, the utility model can obtain the dry air of low dew-point temperature.

Below in conjunction with accompanying drawing the utility model is further described.
