Be further used as the improvement of technical solutions of the utility model, condensation liquefaction retracting device comprises liquefaction recovery casing and reclaims the hot air duct of casing through liquefaction, reclaim casing with liquefaction and be connected cascade type heat pump and hot water storage tank, between cascade type heat pump and hot water storage tank, be provided with water pump.
Be further used as the improvement of technical solutions of the utility model, the bottom that casing is reclaimed in liquefaction is provided with leakage fluid dram.
Be further used as the improvement of technical solutions of the utility model, on the second new wind air channel, air-valve be installed.
The beneficial effects of the utility model: this drying unit that can effectively carry out waste heat recovery is connected heat reclamation device with baking oven, and by with the condensation liquefaction retracting device recovery waste heat in heat reclamation device composition loop, and hot and humid airborne heat and organic solvent after drying are reclaimed fully, thereby effectively improve the energy utilization rate of drying unit.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram.
Detailed description of the invention
With reference to Fig. 1, the utility model is a kind of drying unit that can effectively carry out waste heat recovery, comprise baking oven 4 and be linked to be the heat reclamation device 1 in loop with baking oven 4 by pipeline, be positioned at the heater 3 that is connected with the second new wind air channel 10 and heats for new wind on the pipeline of baking oven 4 inlet sides, in heat reclamation device 1, be provided with heat exchanger fin 13, the opposite side that is positioned at heat exchanger fin 13 is also provided with the condensation liquefaction retracting device 5 that is connected to form waste heat recovery loop with heat reclamation device 1, is also provided with the first new wind air channel 9 between condensation liquefaction retracting device 5 outlet sides and heat reclamation device 1 inlet side.
This drying unit that can effectively carry out waste heat recovery is connected heat reclamation device 1 with baking oven 4, and by forming condensation liquefaction retracting device 5 recovery waste heats in loop with heat reclamation device 1, and hot and humid airborne heat and organic solvent after drying are reclaimed fully, thereby effectively improve the energy utilization rate of drying unit.
As the utility model preferred embodiment, condensation liquefaction retracting device 5 comprises liquefaction recovery casing and reclaims the hot air duct of casing through liquefaction, reclaim casing with liquefaction and be connected cascade type heat pump 6 and hot water storage tank 8, between cascade type heat pump 6 and hot water storage tank 8, be provided with water pump 7.
As the utility model preferred embodiment, the bottom of liquefaction recovery casing is provided with leakage fluid dram 51.
As the utility model preferred embodiment, on the second new wind air channel 10, air-valve 2 is installed.
When this drying unit has just been started shooting, open by controller control air-valve 2, outside air can enter heater 3 by the second new wind air channel 10 and carry out heat treated, the high temperature air producing after heating enters in baking oven 4 and dries drying object, and the hot and humid air producing after oven dry object enters into heat reclamation device 1 by the first return airway 11 again and carries out exchange heat.Now, controller control air-valve 2 cuts out again, outside air can be first entered and in heat reclamation device, is carried out exchange heat by the first new wind air channel 9, after temperature raises, enter again heater 3 and carry out heat treated, the high temperature air producing after heating enters baking oven 4 by airduct dries object, and the hot and humid air producing after drying enters into heat reclamation device 1 by the first return airway 11 again and carries out heat recovery, thereby can reach recycling of heat.
Entered into condensation liquefaction retracting device 5 inside by the air after heat exchange by airduct and carry out condensation liquefaction recovery, in air, organic solvent is condensed into liquid, by leakage fluid dram 51, organic solvent is discharged to condensation accumulator tank and carries out the recovery of organic solvent.The Cryogenic air of having removed majority of organic solvent composition has absorbed condensation and has reclaimed the heat discharging, temperature raises, the air of high temperature is entered in cascade type heat pump 6 and is carried out after heat treated by airduct, carry out heat exchange with the water in hot water storage tank 8, be used to provide hot water, the Cryogenic air after another part heat exchange is transmitted back to the first new wind air channel 9 by the second return airway 12.
Use in the process of this drying unit, outside air has first promoted and enters into heater 3 after temperature again and carry out heat treated by absorbing heat in heat reclamation device 1, does like this, has reduced the heat time of heater 3 and has added heat power consumption, good energy saving property.
Enter in heat reclamation device 1 by the air of heat exchange and enter and in condensation liquefaction retracting device 5, carry out condensation liquefaction recovery, organic solvent is precipitated, and by effective recycling, the Cryogenic air of having removed organic solvent reclaims discharged heat by absorption condensation, temperature raises, by after cascade type heat pump 6 heat treated, be used to provide domestic hot-water, and after another part heat exchange, Cryogenic air is transferred back the recycling that carry out again in the first new wind air channel 9 again.Do like this, hot and humid airborne heat and organic solvent after drying are reclaimed fully, not only saved the energy, improved efficiency, and effectively protected environment again.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
