Description
Technical field
The utility model relates to a kind of heat pump dryer, especially a kind of heat pump dryer with waste heat recovery plant.
Background technology
At present, conventional heat pump drying machine structure designs as shown in Figure 1: the composition such as heat pump drying unit 1, heat pump heat exchanging unit 2, oven dry hangar body 3, go-cart 4, wet-emitting blower 5, heat pump drying unit absorbs heat in air, being discharged into by heat pump heat exchanging unit dries in hangar body, promote the temperature of drying material in air themperature in hangar body and go-cart, water evaporates in material, hot and humid air in oven dry hangar body is discharged in air by wet-emitting blower, dry in hangar body simultaneously and suck fresh cold air, reach the effect of material drying.Be discharged in air by hot and humid air, reduce and dry in hangar body while air humidity, also discharged by a large amount of heats, namely hydrofuge used heat, both caused pollution to environment, wasted resource.
Summary of the invention
The purpose of this utility model solves problems of the prior art, provides that a kind of thermal efficiency is high, the heat pump dryer of remarkable in economical benefits.
For achieving the above object, the utility model adopts following technical scheme: a kind of heat pump dryer with waste heat recovery plant, comprise heat pump drying unit, heat pump heat exchanging unit, dry hangar body and go-cart, described heat pump heat exchanging unit and go-cart are arranged at dries in hangar body, heat pump drying unit is connected with heat pump heat exchanging unit, also comprise waste heat recovery plant, described waste heat recovery plant is arranged at dries hangar external body, comprise air port A, B, C, D, be communicated with oven dry hangar body by air port A, B.
Operation principle: heat pump drying unit absorbs heat in air, being discharged into by heat pump heat exchanging unit dries in hangar body, promote the temperature of drying material in air themperature in hangar body and go-cart, water evaporates in material, dry hot and humid air in hangar body and enter waste heat recovery plant by air port A, be discharged in air by air port D, fresh cold air enters waste heat recovery plant by air port C simultaneously, being drained into by air port B dries in hangar body, fresh cold air and hot and humid air carry out heat exchange in waste heat recovery plant, but do not carry out air exchange, becoming high temperature dry air enters in oven dry hangar body, namely hydrofuge used heat is recycled, heating fresh cold air.
Compared with prior art, tool has the following advantages the utility model: the thermal efficiency is high, and have significant economic benefit, the rate of recovery reaches more than 12% simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model background technology structural representation;
Fig. 2 is the utility model example structure schematic diagram.
Detailed description of the invention
Be further described below in conjunction with accompanying drawing 2 pairs of the utility model: a kind of heat pump dryer with waste heat recovery plant, comprise heat pump drying unit 1, heat pump heat exchanging unit 2, dry hangar body 3 and go-cart 4, described heat pump heat exchanging unit 2 and go-cart 4 are arranged at dries in hangar body 3, heat pump drying unit 1 is connected with heat pump heat exchanging unit 2, also comprise waste heat recovery plant, described waste heat recovery plant is total heat recovery device 5, described total heat recovery device 5 is arranged at dries hangar body 3 outside, comprise air port A, B, C, D, by air port A, B is communicated with oven dry hangar body 3, described air port A is hot and humid air inlet, air port D is hot and humid air exhaust port, air port C is fresh cold air air inlet, air port B is fresh cold air exhaust outlet.
Operation principle: heat pump drying unit 1 absorbs heat in air, being discharged into by heat pump heat exchanging unit 2 dries in hangar body 3, promote the temperature of drying material in air themperature in hangar body 3 and go-cart 4, water evaporates in material, dry hot and humid air in hangar body 3 and enter total heat recovery device 5 by air port A, be discharged in air by air port D, fresh cold air enters total heat recovery device 5 by air port C simultaneously, being drained into by air port B dries in hangar body, fresh cold air and hot and humid air carry out heat exchange in total heat recovery device 5, but do not carry out air exchange, becoming high temperature dry air enters in oven dry hangar body 3, namely hydrofuge used heat is recycled, heating fresh cold air.
The utility model structure can be used for drying various materials, such as betel nut.Above-described embodiment is only illustrate explanation of the present utility model, does not form the restriction to the utility model structure.
