In heat-conducting work medium on, radiating riser is rotated with dryness storehouse, and heat-conducting work medium is by thermal energy conduction in dryness storehouse in radiating riser
On warehouse, the dryness storehouse of cooling section be may be dipped in cooling bath, be the conduction oil or water of low temperature in cooling bath, low temperature it is thermally conductive
Oil or water cool down the warehouse of dryness storehouse cooling section, and the high-temperature material after drying can radiate to have obtained cooling；Low temperature
Conduction oil or water obtain the conduction oil or water that become high temperature after energy heats, can be with UTILIZATION OF VESIDUAL HEAT IN, by the conduction oil after heating
Or water is transported to applicable local UTILIZATION OF VESIDUAL HEAT IN.
4, temperature of high-temperature material is spent 40-60 after the drying described in this；The temperature of Cryogenic air outside dryness storehouse is zero
It is 20 degree -30 degree lower；The thermally conductive oil temperature in cooling bath being low temperature is subzero 10 degree -30 degree, is the water of low temperature in cooling bath
Temperature is 5-30 degree.The temperature difference of the temperature of the temperature with Cryogenic air of material or low temperature conduction oil or water at low temperature is bigger after drying,
The cooling effect of material is better, and the air heated after cooling material or conduction oil or water are transported to applicable local waste heat benefit
With.
The energy consumption index for having the vacuum conductive drying of the rotary-drum vacuum dryness storehouse of cooling section is 2800-4000kj/kg, and
The energy consumption index of convective drying is 4000-7500kj/kg.
1, the thermal energy availability of convective drying generally only has 20-50%, and vacuum conductive drying theoretically can be with
Close to 100%, the thermal energy availability of actually vacuum conductive drying can achieve 60-80%.
2, vacuum conductive drying is than convective drying energy conservation 30-50% under normal circumstances, this is because vacuum conductive drying is not
Hot-blast Heating material is needed, it is small by the thermal losses for being vented lost.
The present invention has the advantages that with existing roller drying storehouse ratio: a kind of rotary-drum vacuum dryness storehouse having cooling section
Heat exchange be dryness storehouse three-dimensional heat exchange；Heat-conducting work medium in heat pipe is heated the energy heats of the carrying of the heat-conducting work medium in storehouse
And phase transformation vaporizes, the thermal energy that the heat-conducting work medium of vaporization carries carries out thermally conductive heat exchange, the heat exchange area of increase to material by heat pipe
The thermally conductive heat transfer rate for improving thermal energy, strengthens dry materials efficiency, has reached the drying purpose of Quick material.In dried object
When material, have the rotary-drum vacuum dryness storehouse of cooling section under the effect of external force rotary motion when, helical blade has stirring and propulsion
Function, material is prevented from caking in dry in-bin drying, improves the dry mass of material, it is dry after material obtained in cooling section
To cooling.Leakage is generated when damage occurs in a certain heat pipe, does not influence the use of entire dryness storehouse.
