Description
Technical field
The utility model relates to a kind of drying device, relates in particular to a kind of phase-change thermal storage type heat pump-solar association drying device.
Background technology
Drying is one of the most ancient unit operations, extensive use national economy every field.Simultaneously, drying also is the bigger technical process that consumes energy, and in developed country, about 10% fuel is used for drying.In traditional drying equipment, convective drying is simple in structure, easy to operate with it, adaptability is widely used by force, is to use maximum a kind of drying equipments in producing at present.The shortcoming of convective drying is that the thermal efficiency is very low, generally has only 30%～60%, and its main cause is because the direct emptying of dry run waste gas is not only taken away waste heat because of waste gas and caused waste, and polluted environment.Though in the minority convective drying, adopt the part waste gas circulation can reclaim a part of waste heat, be subjected to the waste gas circulation quantitative limitation, generally only be 20%～30%.
Solar energy drying (Solar Drying) is the heat energy that utilizes solar radiation, the drying means that the water evaporates in the wet stock is removed.Compare with the drying means that utilizes other energy, solar energy drying has following advantage: clean hygiene, do not pollute material and environment; Solar energy is inexhaustible, does not have the lack of energy problem; Solar energy has everywhere, need not exploit and transport; Other energy resource consumptions are low in the dry run, and operating cost is low.Yet there is following deficiency in solar energy drying: dispersed big, calorific value is low; Temperature rise is little, and rate of drying is low; Intermittence and unstability; Drying efficiency is low.
Heat pump can be converted into the latent heat that the water vapour condensation in the dry run exhaust gas discharged discharges the sensible heat by condenser, and heat pump has been considered to a kind of effective energy reclaiming method.Particularly heat pump combines with good drying condition, and this makes heat pump drying be widely used in the drying of heat sensitivity materials such as timber, cereal, fruits and vegetables, aquatic products and seed.Heat pump drying has energy savings, product quality height, the drying condition adjustable extent is wide and remarkable advantage such as environmental friendliness.But in the middle and later periods of heat pump drying process, mainly be remove by in the dry material in conjunction with water.This part is very little in conjunction with the ratio that water accounts for total moisture removal, yet owing to shrink back to inside gradually in dried wet interface, makes that the mass tranfer coefficient between air and the dried material diminishes, and removing these moisture needs very long drying time and consume more energy.And because the mass tranfer coefficient between air and the dried material is little, it is very little to make hothouse import and export the air condition variation, has influenced evaporimeter cool-down dehumidification ability, the sensible heat and the latent heat of evaporimeter absorption moisture are limited, heat pump operating condition variation, drying efficiency reduces, and prolong drying time.Box heat pump drying device, a collection of dry materials be for up to 12～16h, even longer.
Summary of the invention
The purpose of this utility model is to provide a kind of phase-change thermal storage type heat pump-solar association drying device, this device makes full use of solar energy, dry run exhaust gas discharged heat energy, and the dry run energy consumption is low, rate of drying fast, dry back product quality is high and dry production cost is low.
The utility model is achieved like this, it comprises thermal storage device, homogenating plate, drier, phase-change material, evaporimeter, condenser, blower fan, heat pump casing, solar thermal collector, it is characterized in that thermal storage device connects solar thermal collector, solar thermal collector connects phase-change material, phase-change material connects drier, drier connects evaporimeter by pipeline, evaporimeter communicates with condenser, the condenser gas outlet connects blower fan, the air outlet of blower fan connects phase-change material, the drier side connects homogenating plate, and blower fan is in the heat pump casing, and the heat pump casing is connected with door.
Technique effect of the present utility model is: have remarkable energy saving effect, monoblock type, dry run are easy to control, and dry run is stable, and the dry products quality is good, and dehumidifying effect is strong, and it is good to absorb sensible heat latent heat, drying efficiency height, sealed construction, safety in production.

The specific embodiment
As Fig. 1, shown in Figure 2, the utility model is achieved like this, it comprises thermal storage device 1, homogenating plate 2, drier 3, phase-change material 4, evaporimeter 5, condenser 6, blower fan 7, heat pump casing 8, door 9, solar thermal collector 10, it is characterized in that thermal storage device 1 connects solar thermal collector 10, solar energy heating 10 devices connect phase-change material 4, phase-change material 4 connects drier 3, drier 3 connects evaporimeter 5 by pipeline, evaporimeter 5 communicates with condenser 6, condenser 6 gas outlets connect blower fan 7, and the air outlet of blower fan 7 connects phase-change material 4, and drier 3 sides connect homogenating plate 2, blower fan 7 is in heat pump casing 8, and heat pump casing 8 is connected with door 9.During use, at first by absorbing solar energy by heat collector 10 very much, the solar energy that absorbs directly acts on phase-change material 4, phase-change material 4 and drying medium (air) heat-shift from the low temperature and low humidity of forcing blower fan 7 outlets, then the air of high temperature low humidity enters and acts on dry thing in the drier 3, be exactly the timing dehumidifying operating condition of heat pump at last, unnecessary heat is stored in the thermal storage device 1 in the time of dry run.Thermal storage device 1 discharges heat simultaneously with phase-change material 4, from the air of forcing blower fan 7 to come out, further heating under the effect of phase-change material 4, the air of the high temperature low humidity after the heating enters and takes away dry thing moisture content in the drier 3, also be the operation of heat pump process at last, but under this condition, heat pump alternate run under the operating mode in dehumidifying operating condition and operation of heat pump operating mode two.Main cause is the heat source insufficiency that thermal storage device 1 provides.
