The utility model solar energy and heat pump united drying are brought into play the advantage of solar energy and two kinds of methods of heat pump removal moisture drying fully; Both energy-conservation, pollution-free; Continuously-running carries out drying operation again, learns from other's strong points to offset one's weaknesses each other, has remedied defective separately; Improved the capacity usage ratio of system, also successful solution the high and solar drying of traditional hot blast cocoon kitchen range oven dry energy consumption receive the problem of weather condition restriction.The solar heat pump dry technology can satisfy the needed temperature and humidity requirement of silk cocoon stoving process, and because the efficient solar energy that uses helps energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, frequency-changeable compressor 1, reservoir 2, condenser 3, heating power expansion valve 4, dehumidifying evaporimeter 5, evaporator with heat pump 6, axial flow blower 7, drying box 8, solar energy air heat collector 9, air-valve M1, air-valve M2, air-valve M3, air-valve M4, air-valve M5, drier intake air temperature detector 11, the humidity measurement instrument 12 of working off one's feeling vent one's spleen of drier, silk cocoon baking rate are weighed and are detected measurement mechanism 13, heat collector blast pipe resistance control valve 14, heat collector outlet temperature detector 15, refrigerant bypass magnetic valve 16 in the utility model.
The exhaust end of frequency-changeable compressor 1 is connected with condensers in being installed in drying box 8; Condenser 3 is connected with reservoir 2; Reservoir 2 and heating power expansion valve 4, the dehumidifying evaporimeter 5, the evaporator with heat pump 6 that are contained in the airduct are connected; The evaporating pressure of heating power expansion valve 4 control dehumidifying evaporimeters 5 and evaporator with heat pump 6, the back-steam of evaporator with heat pump 6 is got back to the inlet of frequency-changeable compressor 1.It is solar energy drying operating mode, heat pump operating mode, three kinds of situation of combined solar energy heat pump work operating mode that the air of airduct pipeline flows away to being divided into.During the solar energy drying operating mode; Frequency-changeable compressor 1 is not worked, and air-valve M3, air-valve M4 close, and the house steward's of air collector thermal air current gets into drying box 8 through axial flow blower 7, air-valve M1, the heat pump condenser 6 of flowing through; Silk cocoon heat exchange in hot blast and the drying box 8 on the silk cocoon shelf; The exhaust of drying box 8 is through being equipped with the airduct of dehumidifying evaporimeter 5, and the air-valve M2 that flows through of the air after the dehumidifying sends into the inlet manifold of solar energy air heat collector 9, and house steward's air distribution is to each heat collector; Air obtains solar energy in heat collector, the axial flow blower 7 in the system is all opened.During the heat pump operating mode; Air-valve M3 opens, and air-valve M1, M2 close, and the blower fan of solar energy airduct stops; Frequency-changeable compressor 1 is opened; 5 dehumidifying of dehumidifying evaporimeter are blown in the part exhaust of drying box 8, and the part exhaust is blown over condenser 3 through air-valve M3, axial flow blower 7 and got into drying box 8, and silk cocoon heat exchange, air-valve M5 in hot blast after condenser 3 heating and the drying box 8 on the silk cocoon shelf partly open the capacity that can regulate drying box 8.Air-valve M3, M4 close, and air-valve M1, M2 open, and the blower fan of solar energy airduct is opened; Frequency-changeable compressor 1 is opened, and be the combined solar energy heat pump drying system this moment, and the house steward's of air collector thermal air current is flowed through through axial flow blower 7, air-valve M1 and got into drying box 8 after heat pump condenser 3 heats up; The heat hot blast that air obtains from condenser 3, this moment the compressor 7 heating capacities=required heat of silk cocoon-acquisition solar energy, the solar energy of acquisition is many more; Compressor 7 heating capacities also just can lack more; Reach energy-conservation purpose, partly open, reach the purpose of the capacity of regulating drying box 8 through regulating M5.
1. through opening the different system start and stop of different air-valve control solar heat pump drying systems, reach the optimized operation of system.
Air-valve M3, M4 close, and air-valve M1, M2 open, and all blower fan is opened; Frequency-changeable compressor stops; Be the operation of independent solar energy drying system this moment, and the solar energy that this operating mode is fit to obtain satisfies the state that the required heat of dry silk cocoon and stoving process require, with 15 judgements of solar energy air heat collector outlet temperature detector; Temperature adopts independent solar energy drying system operation during more than or equal to 78 ℃.Air-valve M3 opens, and air-valve M1, M2 close, and the blower fan of solar energy airduct stops, and frequency-changeable compressor 1 is opened, and be independent heat pump drying system operation this moment, when this operating mode is fit to not have solar energy fully.Air-valve M3, M4 close, and air-valve M1, M2 open, and the blower fan of solar energy airduct is opened, and frequency-changeable compressor 1 is opened, and be the combined solar energy heat pump drying system this moment.
2. adopt the intake air temperature of frequency-changeable compressor control drier
The cocoon drying process is divided warm-up phase, constant-rate drying period, 1 section of falling rate of drying, 2 sections of falling rate of drying; The drying box intake air temperature of each section correspondence is respectively 83 ℃, 83 ℃, 80 ℃, 70 ℃; The design detects through drying box 8 intake air temperature and adopts converter technique to control the rotating speed of compressor 1, thereby obtains the intake air temperature of the demands of different of drying box 8.
3. adopt the switching of weight method control drying stage
The baking rate of silk cocoon=(weight of the weight/bright cocoon of dry back silk cocoon) * 100% is installed an electronic scale treasure in the bottom of silk cocoon shelf, and the data that record input computer carries out the baking rate and calculates.When the baking rate reached 62%, the intake air temperature of drier was set and is changed 80 ℃ into, and when the baking rate reached 34%, the intake air temperature of drier was set and changed 70 ℃ into, and when the baking rate reached 25%, dry oven dry finished.Adopt the baking rate as control parameter control drying course, will save the energy and obtain better product quality than the employing method control drying course regularly of routine.
4. the humidity of measuring the outlet of drier 8 is controlled the unlatching of refrigerant bypass magnetic valve, reaches energy-conservation purpose
If the humidity measurement instrument of the outlet of drier 12 indication humidity are lower than 70%; Then open refrigerant bypass magnetic valve 16, refrigerant bypass does not have cold-producing medium dehumidifying evaporimeter 5 coil pipes of flowing through; Temperature can not descend when this moment, return-air was through dehumidifying evaporimeter 5; The condenser 3 required heats that offer drying box 8 reduce, and refrigeration compressor 1 required acting reduces, and reaches purpose of energy saving.
