On this basis, be equiped with control valve between rearmounted refrigerant condenser and the runner treatment region, on the pipeline between control valve and the rearmounted refrigerant condenser, be provided with collateral branch's air intake, and be provided with control valve.Control valve, its function are to regulate the air capacity of handling through 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 guarantee have enough air to flow through rearmounted refrigerant condenser, makes the cold-producing medium that in rearmounted refrigerant condenser, flows by fully cooling.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 in regular turn through I level refrigerating evaporator, II level refrigerating evaporator, runner treatment region, the rearmounted refrigerant condenser of II level, rearmounted refrigerant condenser of I level and processing blower fan; Flow back to the dried material space again, atmosphere c, arranges to atmosphere in regular turn through the preposition refrigerant condenser of I level, the preposition refrigerant condenser of II level, rotary wheel regeneration district and regeneration blower fan through pipeline once more.Two cover refrigeration systems can independently realize start and out of service, also can adopt different cold-producing medium models.
Refrigeration system of the present invention 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 present invention can obtain the dry air of low dew-point temperature.
Below in conjunction with accompanying drawing the present invention is further described.
