Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to Fig. 1 to Fig. 4, solar energy-heat pump combined dryer of the utility model with energy storage, 1 face south cloth of drying box It sets, guarantees that its inclined-plane and top can receive maximum solar radiation, solar energy air heat collector 2 can be according to different ground Reason position is installed according to a conventional method, and other components are according to connection shown in figure.Due to different latitude area solar incident angle degree and Radiation intensity is different, and the bevel angle of drying box and the perpendicular separation distance of material disc can be arranged according to local concrete condition.
Solar energy drying as a kind of clean, free, reproducible energy, have it is energy saving, shorten arid cycle, mention The advantages such as high yield quality and yield rate.It is able to satisfy requirement of most of crops to drying temperature in agricultural production, it can be preferably Ground solve traditional natural ted present in sanitary condition it is poor, the problems such as product property is low.But meanwhile solar energy conduct A kind of intermittent energy source, when exclusive use, are discontinuous, unstable, fluctuate larger.Heat pump drying is to make heat using inverse Carnot's principle Amount transfer is to realize drying.It can realize that Cryogenic air closed circulation is dry using heat pump drying, for the temperature-sensitive of similar crops Property material, dry products quality is high.Warm and humid sky of the heat mainly from recycling hothouse discharge of air is heated in heat pump drying Sensible heat and latent heat in gas, the energy for needing to input only have the wasted work of heat pump compressor, therefore have the characteristics that energy-efficient.
The hot-air system of the utility model is made of two branches, and one is solar heat wind system, by drying box 1, row Wet blower 10, air preheater 11, air-introduced machine 15, solar energy air heat collector 2, phase-change thermal storage case 3 form;One adds for heat pump Hot-air system, by drying box 1, wet-emitting blower 10, the composition such as heat pump system, wherein for heat pump system by evaporator 5, condenser 6 is swollen Swollen valve 7, compressor 8, motor 9 form.Second Electric air valve 18 is with condenser 6 by pipeline through air-introduced machine 15 and auxiliary heater 16 are connected to the air inlet of drying box 1, third Electric air valve 19, the 4th Electric air valve 20 by pipeline successively with solar air Heat collector 2, covert heat storage box 3 are connected to the air inlet of drying box.When being dried, it can be returned as needed using different hot winds Road, when using heat pump hot-air system, the damp-heat air come out from drying box 1 passes through evaporator 5, and vapor condensation therein rises To effect on moisture extraction;Air preheater is equipped with air inlet 12, exhaust outlet 13, condensate drain mouth 14, is a kind of heat-exchanger rig, arranges from drying box Damp-heat air out enters air preheater 11, heats to fresh air, hydrogenesis discharge therein;Solar heat wind system In phase-change thermal storage case 3 in be equipped with aluminum hull paraffin tube bank 4, when daytime, when the hot blast temperature mistake that solar energy air heat collector 2 exports Gao Shi, phase-change thermal storage case 3 absorb the hot-air heat that exports from solar energy air heat collector 2, make paraffin melting, stone when night Wax solidification again releases heat, is re-used as a heat source to drying box 1 and provides heat.
The control system of the utility model (has temperature sensor and humidity sensor by the controller 21 in drying box 1 Device), the first Electric air valve 17, the second Electric air valve 18, third Electric air valve 19, the 4th Electric air valve 20, and auxiliary heating Device 16 forms.Controller 21 in drying box 1 by two kinds of sensor for temperature with the collection of humidity compared with, information is fed back To controller 21, controlling Electric air valve and auxiliary heater 16 by controller 21 can also pass through in the present invention The acquisition data of temperature sensor and humidity sensor are to the first Electric air valve 17, the second Electric air valve 18, third Electric air valve 19, the 4th Electric air valve 20 and auxiliary heater 16 are manually controlled.
The utility model preferentially uses solar energy hot blast drying system, drying means when carrying out fruit and vegetable dryness are as follows: will Material to be dried is put on material disc 25, is placed in drying box 1.It is opened on sun-drenched daytime using solar heat wind system When the beginning, the second Electric air valve 18 is closed, opens the first Electric air valve 17 and third Electric air valve 19, opens air-introduced machine 15, environment Air first enters via the air inlet 12 of air preheater 11, after the heating of solar energy air heat collector 2, is sent into drying box 1 In, material is dried, the damp-heat air come out from drying box 1 is guided via air-introduced machine, right into air preheater 11 Fresh air is preheated, and is dropped exhaust gas and be discharged by exhaust outlet 13, and condensed water is discharged by condensate drain mouth 14;Due to the day within one day Different according to intensity, when daily sunshine starts, solar elevation is small, and photo-thermal dispersion, radiation intensity is smaller, solar energy heating at this time 2 outlet air temperature of device is lower, and as time goes by, solar elevation becomes larger, and radiation intensity becomes larger, and solar thermal collector 2 goes out The air themperature of mouth is got higher, will when the temperature sensor in drying box 1 detects that 1 temperature of drying box is more than 5 DEG C of set temperature Data feedback opens the 4th Electric air valve 20 to controller 21, and hot-air a part that solar thermal collector 2 exports at this time enters Phase-change thermal storage case 3, transfers heat to paraffin tube bank 4, and paraffin absorbs the hot-air heat exported from solar energy air heat collector 2 Amount, makes paraffin melting, and heat is stored, and the hot blast temperature into drying box 1 decreases, its drying temperature is kept to stablize (solar thermal collector outlet air temperature, which is enough heating paraffin wax, makes its thawing, if the fusing point of 54# semi-refined paraffin wax is 54 DEG C, April It is concentrated between 50~80 degrees Celsius to general vacuum tube collector outlet air temperature in November);On the other hand, drying box Vacuum glas-cover board 22 is selected on 1 top and inclined-plane, and entire drying box 1 is equivalent to a greenhouse, solar radiant energy is absorbed, due to place The solar radiation suffered by top and material in the south is most, therefore liftable lifting shelf 26, every layer of object are used in drying box Charging tray 25 is successively gone up and down, and can make material can be by uniform solar radiation;When night no light, hot blast temperature is reduced, white It absorbs the paraffin of enough heats, heat is released, to heat hot wind;After a period of time, discharged when in phase-change thermal storage case 3 Heat gradually decrease, hot blast temperature reduce, at this time close third Electric air valve 19, the 4th Electric air valve 20, open second electricity Dynamic air-valve 18 opens heat pump heating system, after heat pump fluid is compressed via compressor 8, into putting in condenser 6 to dry air Heat, the dry air after heat absorption, which enters in drying box 1, is dried material, and the damp-heat air after drying is via wet-emitting blower 10 It is guided into evaporator 5 and heat release is carried out to heat pump fluid, while dehumidifying, the air after dehumidifying enters air preheater again In 11, it will be discharged after Waste Heat Reuse.In the operation of entire drying system, if hot blast temperature is lower than 5 DEG C of temperature of setting, pass through Controller is opened auxiliary heater 14 and is heated to hot wind, if detecting, temperature is excessively high in drying box 1, can be each by adjusting The air door size of a Electric air valve controls.
