In air-handling chamber 2, be also provided with for being sent into the blower fan 17 of hothouse 1 by the air after condenser 11 heating.As preferably, above-mentioned blower fan 17 is frequency conversion fan.By controlling the rotating speed of blower fan 17, control the air output of blower fan 17, to meet difference be dried material or the requirement of different dry period to air quantity and wind speed.
Need explanation, above-mentioned Analysis of Heat Pump Drying System can also comprise control system, and control system can be according to the kind of drying stage, the material that is dried, and the factor such as external environment is controlled accurately to Analysis of Heat Pump Drying System.Utilize perfect control system, realized the accurate control to each power-equipment in dry run, for improving the quality of dried material, provide strong assurance.
For above-mentioned heat pump drying agricultural product system is further detailed, present embodiment also provides the course of work under the different operating modes of said system:
During heat pump work, under the Action of Wind pressure of outdoor fan 13, impel air to continue to flow through the fin clearance of evaporimeter 10, wherein this part air comprises the Hot wet air heating of discharging from hothouse 1 moisture exhausting port, with the refrigeration working medium heat exchange in evaporimeter 10 pipelines, refrigeration working medium evaporates because absorbing heat, by the liquid of low-temp low-pressure, become the gas of low-temp low-pressure, after boosting, compressor 8 becomes the gas of HTHP, in condenser 11 in air-handling chamber 2, the refrigeration working medium gas of HTHP is emitted heat and is added hot-air, self is condensed into liquid working medium, the liquid that becomes low-temp low-pressure after expansion valve throttling enters evaporimeter 10 and starts circulation next time.By air outlet 4, be sent to hothouse 1 with atmosphere temperature rising after condenser 11 heat exchange and carry out heat exchange with the agricultural product that are dried.
Most agricultural product need to be got rid of the moisture of material as soon as possible in the dry starting stage, and this one-phase is commonly referred to the large hydrofuge stage, as shown in Figure 2 be the mode of operation of heat pump Drying system of agricultural products in the large hydrofuge stage.In order to guarantee the CF of dried material, dry the control valve at fresh wind port 6 places is in full-gear at the beginning, and the air quantity controller at return air inlet 5 places is closed completely.The hot-air that enters hothouse 1 completes once the wet exchanged heat of heat with the agricultural product that are dried and is discharged completely by moisture exhausting port 14.Because heated air of this stage is the fresh air from environment, heat pump needs continuous firing, constantly for the agricultural product that are dried provide required heat.Wherein according to the difference of dried material, can be by regulating the rotating speed of frequency conversion fan 17 air quantity of for a change blowing.
When dry materials reaches certain drying process requirement, hydrofuge amount reduces, if be still dried and will cause energy waste according to the mode of operation of system shown in Figure 2, can adopt the pattern of heat pump Drying system of agricultural products as shown in Figure 3 this moment.Concrete is: by regulating the aperture of the control valve at fresh wind port 6 places and the air quantity controller at return air inlet 5 places, can obtain the air of desired moisture level, fresh air and damp-heat air mixing condenser 11 of discharging from hothouse 1, after condenser 11 heating, by blower fan 17, sent into hothouse 1, through carrying out the wet exchange of heat rear portion with material, through moisture exhausting port 14, discharge hothouse 1, a part enters next circulation through return air inlet 5.The air capacity of sending into hothouse 1 in this dry run is required to adjust according to drying process by blower fan 17.
When dry materials is to the later stage, seldom, the humidity of the hot-air of heat exchange changes not quite the moisture in material with it, can utilize the enclosed circulation pattern of heat pump Drying system of agricultural products as shown in Figure 4 to carry out dried material.This system is the control valve of closing fresh wind port 6 places completely, opens the air quantity controller at return air inlet 5 places, and air-supply wind speed requires to regulate by blower fan 17 according to drying process.Owing to not having extraneous air to enter drying box, thus do not have gas to discharge from moisture exhausting port 14 yet, generally, under this pattern, because material moisture is low, evaporation slowly, few with the wet exchange capacity of heat of air, the corresponding minimizing of heat that heat pump will provide, heat pump enters discontinuous operation state.
In sum, the heat pump Drying system of agricultural products with Waste Heat Recovery that the present invention proposes, the control valve at fresh wind port 6 places is installed in employing additional, the air quantity controller at return air inlet 5 places and the mode of frequency conversion fan have been eliminated the single dry pattern of traditional drying system, according to different dry demands, can free adjustment air-supply humiture and air quantity, guaranteed that same drying equipment can be for the demand to different dry drying process of different material, the kuppe 16 that hothouse 1 top installs additional has reduced the hydrofuge resistance of periphery material, make dry more even, waste gas by drawing moisture exhausting port 14 is to evaporimeter 10, reduced the risk of evaporimeter 10 frosting under low temperature environment.By the control of different drying modes, make whole system energy-conservation obviously, capacity usage ratio is significantly improved simultaneously.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present utility model, within these modes all will fall into protection domain of the present utility model.
