Description
Technical field
This utility model is related to a kind of recuperation of heat air drier.
Background technology
The air drier of existing energy-conservation is to work as medium using coolant, by the liquidation exothermic reaction of the coolant in condenser Lai
By cold air heating, then deliver to user side.Hot blast is changed into useless wind through user side after using, and in useless wind, generally existing is substantial amounts of residual
Stay heat.As being used, that is, it is used for preheating the fresh air under room temperature, you can realize significantly energy-conservation.Right in existing equipment
The waste heat recovery of useless wind is not thorough, leads to subsequently the environmental protection treatment of useless wind is difficult to implement.New after being preheated by useless wind simultaneously
Wind can lead to the heat of condenser cannot discharge completely, equally causes the waste of the energy.Therefore, we devise a kind of heat and return
Receive air drier.
Utility model content
For solving deficiency of the prior art, the purpose of this utility model is to provide a kind of recuperation of heat air drier, purport
Solving, existing hot air drying acc power is big, and service life is not long, and coolant heat release utilization rate is not high, and useless wind waste heat wastes, useless wind
Not tractable problem.
For achieving the above object, the technical solution of the utility model is: a kind of recuperation of heat air drier, including evaporation
Device, compressor, condenser one, condenser two, double back journey heat-exchangers of the plate type, blower fan, described vaporizer, compressor, condensation
Pass sequentially through refrigerant pipe between device one and condenser two and be connected formation closed loop；It is provided with described double back journey heat-exchangers of the plate type and pass through
Wear the fresh air pipeline of the first backhaul and the second backhaul, the air outlet of fresh air pipeline connects the air inlet of condenser one by blower fan, newly
The air inlet of wind pipeline connects the air outlet of condenser two；Described condenser two is located above double back journey heat-exchangers of the plate type, and
The air inlet of condenser two is provided with fresh air filter screen；The air outlet of described condenser one is provided with electric heater；Described is double
The air inlet of the second backhaul of backhaul heat-exchangers of the plate type connects useless wind backwind tube, and the air outlet of the second backhaul meets entering of the first backhaul
Air port, the air outlet of the first backhaul connects vaporizer.
Preferably, being provided with pressure expansion valve in refrigerant pipe between described condenser two and vaporizer.
The beneficial effects of the utility model: improve coolant utilization rate, and reclaimed amount of residual heat, be easy to energy-conserving and environment-protective,
Advantageously reduce the power of air drier, improve service life, optimize equipment connection structure simultaneously, prevent blower fan in high temperature
Under fragile, shorten hot blast stroke, reduce heat losses,
Brief description
Fig. 1 is structure principle chart of the present utility model.
Specific embodiment
As shown in figure 1, a kind of recuperation of heat air drier, including vaporizer 1, compressor 2, condenser 1, condenser two
4th, double back journey heat-exchangers of the plate type 5, blower fan 13, between described vaporizer 1, compressor 2, condenser 1 and condenser 24 according to
Secondary by refrigerant pipe 6 connect formed closed loop；It is provided with described double back journey heat-exchangers of the plate type 5 and run through the first backhaul 11 and second
The fresh air pipeline 7 of backhaul 12, the air outlet of fresh air pipeline 7 connects the air inlet of condenser 1 by blower fan 13, fresh air pipeline 7
Air inlet connects the air outlet of condenser 24；Described condenser 24 is located above double back journey heat-exchangers of the plate type 5, and condenser
24 air inlet is provided with fresh air filter screen 8；The air outlet of described condenser 1 is provided with electric heater 9；Described double back
The air inlet of the second backhaul 12 of journey heat-exchangers of the plate type 5 connects useless wind backwind tube 10, and the air outlet of the second backhaul 12 connects first time
The air inlet of journey 11, the air outlet of the first backhaul 11 connects vaporizer 1.Coolant between described condenser 24 and vaporizer 1
It is provided with pressure expansion valve 14 in pipe 6.Fresh air pipeline 7 of the present utility model machine 13 of first giving a dinner for a visitor from afar connects condenser 1 again so that blower fan 13
Run at reduced temperatures, be hardly damaged, meanwhile, the condensed device of fresh air 1 is directly expelled to user by air outlet after heating up
End, can reduce thermal loss.The air outlet of condenser 1 is provided with electric heater 9, can be used for improving new air temperature further.
Useless wind enters double back journey heat-exchangers of the plate type 5 through useless wind backwind tube 10, and successively right in the second backhaul 12 with the first backhaul 11
Fresh air pipeline 7 carries out heat exchange, and the wind that subsequently gives up is discharged through vaporizer 1.In vaporizer 1, liquid refrigerants needs heat absorption evaporation, enters one
Step make use of the heat of useless wind, so that useless air temperature is down to minimum, is easy to environmental protection treatment.Fresh air after being preheated enters condenser one
So that condenser 1 runs at a higher temperature when 3, the heat in condenser 1 can be led to cannot to discharge completely, therefore
Heat can be discharged further in fresh air pipeline 7 entrance point by condenser 24, increase operation rate so that equipment more energy-conservation
Efficiently.It is provided with pressure expansion valve 14 in refrigerant pipe 6 between condenser 24 and vaporizer 1, the pressure in refrigerant pipe 6 can be improved,
Reduce the boiling point of coolant, be easy to gasify.To sum up, the condensed device of fresh air 24 preheats and enters double back journey heat-exchangers of the plate type 5 again
Preheating, is expelled to user side by condenser 1, makes full use of useless wind waste heat, and plant capacity can be greatly reduced, and is conducive to
The environmental protection treatment of useless wind.The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All any modification, equivalent or improvement made within spirit of the present utility model and principle etc., should be included in this reality
Within new protection domain.
