Description of drawings
Fig. 1 is the structural representation of the energy saving and environment friendly temperature air-source heat pump drying system of the utility model.
Fig. 2 is the automatic control system block diagram of the energy saving and environment friendly temperature air-source heat pump drying system of the utility model.
The specific embodiment
With reference to Fig. 1, a kind of temperature air-source heat pump drying system comprises drying room and source pump, it is characterized in that: described drying room arranges air circulation duct, air circulation duct one end sets out the air port towards the circulating fan 1 of circulation canal inside, and circulating fan 1 air outlet place arranges auxiliary hot charging and puts 9; On the exterior wall of drying room, wet-emitting blower is set.
Because the air circulation duct area is little, the air quantity of blower fan is certain, and air flowing velocity in passage is fast, and short with the time of contact of the lower exterior wall of temperature, the heat of loss is also just little.Air circulation duct ceiling side end arranges circulating fan 1, and purpose is that hot-air is circulated in drying room, improves the utilization rate of air heat.
Described circulation canal cross-sectional area is less than or equal to 1/4 of drying room minimum sectional area.For example, if drying room is cuboid, described circulation canal cross-sectional area should be less than 1/4 of the minimum area simultaneously of this cuboid area.In air circulation duct, the flow velocity of gas greater than 3 times of gas flow rate in drying room, can obviously reduce the heat loss of air in circulation canal at this moment.
In addition, because winter temperature is lower, be to improve drying efficiency, described circulating fan 1 air outlet place arranges auxiliary hot charging and puts 9.Circulating fan 1 air outlet place arranges auxiliary hot charging and puts 9, and is through temperature reduction after drying room and material-heat-exchanging, minimum in circulating fan 1 air outlet place temperature due to air, add that herein auxiliary hot charging puts, the auxiliary hot charging of energy increase is put the temperature difference with air, increases the rate of heat addition of air, reduces the loss of heat.
Further, described auxiliary hot charging puts 9 for electric heater.Adopting electric heater is to control in order to use safety and to be convenient to controller, and the current switching that controller only need be controlled electric heater gets final product, and it can be also traditional heat resource form that certain auxiliary hot charging puts 9, as heating take coal or natural gas as raw material.
Described source pump comprises the compressor 5 of the compression heat hot pump work substance that drying room is outer, the choke valve 6 of throttling expansion heat pump fluid, the loop of heating heat exchanger 3 compositions of air in drying room for heat pump fluid.
The source pump operation principle: source pump working medium (can be CO
2, NH
3Deng) the compressed machine 5 rear volume-diminished of compression, temperature raises, heated working medium enters air exchange heat in inherent heat exchanger 3 places of drying room and room by the loop, after adding hot-air, working medium reduces through choke valve 6 throttling expansion temperature, the working medium of throttling cooling through the loop drying room outside and the outside air heat-shift, absorb the air heat, so recycle the air in drying room outer air heat heating room.
The described circulation canal other end arranges heat exchanger 3, sets out the air port near heat exchanger 3 towards by the blower fan 2 of material drying.Can accelerate like this heat exchange of circulated air and heat exchanger 3, the air that is heated by heat exchanger 3 in circulation canal is carried by blower fan 2 and is removed the heating, drying article, and thermal current rises and sends air circulation duct continuation circulating-heating article to by circulating fan 1.
Further, described blower fan 2 is for being placed in the axial flow blower on ground.In drying room, heated air is to carry by blower fan 2 to remove to add thermal material, and because cold air sinks, in the room, air can be heated evenly better in order to make, and described blower fan 2 is placed in ground.Because the axial flow blower cost is lower, so preferred axes flow fan herein can certainly be the blower fan of other forms such as centrifugal blower, positive displacement blower fan.
Temperature Humidity Sensor is set in drying room, and drying system comprises that also controlled circulation blower fan 1 in the set of signals of returning according to sensor, auxiliary hot charging put 9 and the controller of wet-emitting blower 7.
Controller can be at any time changes switch pair wet blower and assisted heating device according to the temperature and humidity of drying room, thereby the working medium flow of adjusting heat pump unit reaches the purpose of regulating the drying room temperature and humidity, and its automatic control system block diagram as shown in Figure 2.Controller can be based on controller or other PLC controllers of AD μ C834 chip, and resistance or voltage signal that the Temperature Humidity Sensor by drying room inside sends back are regulated system.Concrete, during higher than setting value, the frequency converter in controller adjusting heat pump unit reduces the flow of source pump working medium, thereby reduces the heat of air in the heating drying room, reduces the drying room temperature when the drying room temperature; Lower than when setting value, the frequency converter in controller adjusting heat pump unit increases the flow of source pump working medium when the drying room temperature, thereby increases the heat of air in the heating drying room, rising drying room temperature; When the source pump frequency converter is transferred to peak power, the drying room temperature is during still lower than setting value, and controller is connected auxiliary hot charging and put 9 electric current, adds hot-air; Higher than when setting value, controller starts wet-emitting blower 7 when humidity in drying room; Lower than when setting value, controller cuts out wet-emitting blower 7 when humidity in drying room.
Described wet-emitting blower 7 is arranged in air circulation duct.Can not destroy the circulation of air in the room like this, can be so that in drying room, heat distributes more even.
In order to reduce the flow resistance of air, the corner of described air circulation duct arranges the iron sheet 8 that seamlessly transits.
Described drying room is arranging fresh wind port 4 near on the exterior wall of source pump.Fresh wind port is in closed condition at ordinary times, when wet-emitting blower is opened, opens fresh wind port, allows dry fresh air enter drying room.Fresh wind port 4 be arranged near source pump be for make newly advance air can with the working medium heat exchange rising temperature of the compressed heating of source pump, reduce newly to advance Cryogenic air and enter drying room to the equalized temperature destructiveness in the room.
