The specific embodiment
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 1, at first adopting heat pump to take full advantage of can in the external environment condition low-temperature heat source, effectively the reduction system imports energy, reach purpose of energy saving, because heat pump can heat pump can utilize in the low-temperature heat source can, 3 to 4 times heat energy of self institute's energy requirement is sent to high temp objects from cryogenic object.Native system is in when operation, and the liquid refrigerant of low-temp low-pressure (for example freon) at first absorbs heat and is vaporized into low-pressure steam from low-temperature heat source (underground water) in evaporimeter.Refrigerant gas is compressed into the steam of HTHP in compressor then, and this high temperature and high pressure gas with the new air intake of heat transferred, improves new wind-warm syndrome degree at the condenser place, reaches the purpose of the new wind of preheating.At this moment, refrigerant gas is condensed into the normal temperature high voltage liquid refrigerant.Remove moisture and impurity from the liquid refrigerant drying filter that condenser comes out, the magnetic valve of flowing through becomes the low-temp low-pressure liquid refrigerant and enters evaporimeter after heating power expansion valve throttling step-down.The heat that the low-temp low-pressure liquid refrigerant absorbs recirculated water in the evaporimeter evaporation that keeps all becomes the overheated dry flue gas of low-temp low-pressure during the arrival evaporator outlet, return the compressor air suction valve.Circulate so repeatedly, reach the purpose of the new wind of preheating.
During drying system of the present invention operation, fresh hot blast enters in the drying plant, discharge through air outlet, air outlet place configuration secondary return air device, a part of air-out participates in the circulation of two subthermal energies and directly utilizes, another part as the security exhaust amount discharged to beyond the system.As this part of security exhaust, adopt heat exchange of heat pipe that its waste heat is carried out the high efficiente callback utilization, the fresh wind that enters system is carried out preheating.The operation principle of heat exchange of heat pipe: air draft is through the evaporation ends of heat exchange of heat pipe, heat pipe one end is heated, media fluid in the capillary evaporates rapidly, steam flows to an other end (condensation end) under small pressure differential, when fresh wind passed through condensation end, the medium steam in the heat pipe was met the cold heat that discharges, regelation becomes liquid, liquid then leans on the effect of capillary force to flow back into evaporation ends along the inside heat pipe porous material, and so circulation is more than, and heat reaches an other end by heat pipe one end.This heat transfer theory of heat pipe be exactly in the tube phase transformation of medium carry out, be efficiently and promptly, its heat transfer efficiency can reach more than 60%.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the method that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification still belong in the scope of technical solution of the present invention.
