Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing And specific embodiment is described in detail.
The utility model provides a kind of heat pump drying equipment, as shown in Figure 1, including drying room 1, vaporization chamber 2 and heat pump, heat Pump includes evaporator 3, compressor 4, condenser 5 and the intercooler 6 being connected by circulation by pipeline together, 1 He of drying room It is separated between vaporization chamber 2 by first partition 7, air inlet 8 and air outlet 9 is provided on vaporization chamber 2, evaporator 3 is arranged in outlet air At mouth 9, the first blower 10 is provided on evaporator 3, intercooler 6 is arranged in vaporization chamber 2, and the setting of condenser 5 is being dried In room 1.
The heat pump drying equipment of the utility model is used for being dehydrated to material (agricultural and sideline product, industrial and mining products etc.) When, agricultural and sideline product, industrial and mining products etc. are put into drying room, starting device.
Heat pump in the utility model includes evaporator, compressor, condenser and intercooler, passes through pipeline (copper pipe Deng) connect, there is working medium (fluorine etc.) to circulate in pipeline.
During the drying process, as shown in Figure 2 (in order to enable expression is apparent, the components such as pipeline are omitted in Fig. 2), the first wind Machine work, air is sucked in vaporization chamber outside vaporization chamber, and then air passes through evaporator, outer by air outlet discharge evaporation. When air passes through evaporator, working medium absorbs the heat of air, the gas for high temperature and pressure is then compressed by the compressor, finally cold Heat, the indoor air of heating, drying are released in condenser.For the temperature of working medium after condenser or relatively high, this is practical new Intercooler is arranged in type, and working medium passes through intercooler, with the indoor air heat-exchange of evaporation, the further bosher of one side Matter, so that working medium is by can be absorbed more heats, the indoor air of another aspect heating evaporation, vaporization chamber when evaporator Interior air be heated after through pervaporation device so that evaporator absorbs more heats from air.
In conclusion the utility model cools down working medium and the indoor air of heating evaporation by intercooler, so that work Matter absorbs more heats in evaporator, improves the COP of heat pump, and reduce expansion valve and compressor after working medium cooling Load.
As a kind of improvement of the utility model, drying room 1 includes baking zone 11 and race way 12, baking zone 11 and circulation It being separated between area 12 by second partition 13,13 lower part of second partition is provided with circulation port 17, and condenser 5 is arranged at circulation port, The second blower 14 is provided on condenser 5,13 top of second partition is provided with circulation window 15.
In drying, as shown in Fig. 2, under the action of the second blower, dries indoor air and successively pass through condenser and (follow Collar extension) → baking zone → circulation window → race way → condenser, it circulates, passes through condenser repeatedly, air is at condenser It is heated so that the indoor air heats of drying are more uniform, drying effect is more preferable, and the air in baking zone is from the bottom up Flowing, it is easier to take away the moisture in material, drying effect is more preferable.
In order to enable it is more smooth to dry indoor air circulation, circulation window 15 is preferably rectangle, recycle the width of window 15 with Drying room 1 it is of same size.
Drying stage is carrying out after a certain period of time, and large quantity of moisture can be contained by drying indoor air, is high temperature and humidity air, The effect dried at this time is bad, needs for high temperature and humidity air to be discharged, and the prior art is directly by high temperature and humidity air It is discharged to outdoor, has wasted the heat in high temperature and humidity air.
The utility model is provided with hydrofuge air inlet 16 on drying room 1, and hydrofuge air outlet 18 is provided in first partition 7, in Between cooler 6 be arranged on hydrofuge air outlet.The utility model realizes the utilization to heat in high temperature and humidity air, such as Fig. 3 Shown (in order to enable expression is apparent, the components such as pipeline are omitted in Fig. 3), detailed process are as follows:
Hydrofuge air inlet is opened, under the action of the first blower and the second blower, high temperature and humidity air in baking zone according to It is secondary to pass through circulation window → race way → hydrofuge air outlet → vaporization chamber → rapid steamer → air outlet, at rapid steamer, high temperature and humidity Air is sucked away a part of heat, then within the condenser comes out heat, the indoor air of heating, drying.It is thus real Show the utilization again to heat in high temperature and humidity air, further increases the COP of heat pump.High temperature in discharge baking zone is high While humid air, extraneous air successively passes through hydrofuge air inlet valve → race way → condenser → baking zone, after hydrofuge, It is filled with extraneous dry air in baking zone, then repeats above-mentioned drying course.
Hydrofuge air inlet 16 is arranged in the lower sidewall of race way 12, and hydrofuge air inlet and circulation port are respectively positioned on lower part, and two Person's distance is close, so that during hydrofuge, outside air is after hydrofuge air inlet enters race way, in the work of the second blower Under, baking zone is entered by condenser, without being flowed up under the action of the first blower, is entered by hydrofuge air outlet Vaporization chamber.Circulation window and hydrofuge air outlet are respectively positioned on top, and the two distance is close, so that during hydrofuge, high temperature and humidity air By circulation window enter race way after, under the action of the first blower, enter vaporization chamber by hydrofuge air outlet, without It flows downward under the action of second blower, baking zone is entered by condenser.
The utility model passes through arrangement hydrofuge air inlet, circulation port, circulation window, hydrofuge air outlet, air inlet and air outlet Position so that air flowing when will not interfere with each other.
The side wall upper part of vaporization chamber 2 is arranged in air inlet 8, and air outlet 9 is arranged on the rear end face of vaporization chamber 2.
For convenience of control, it is provided with hydrofuge air inlet valve on hydrofuge air inlet 16, air inlet valve, hydrofuge are provided on air inlet 8 Air inlet valve and air inlet valve are all connected with PLC controller.
The intercooler of the utility model can be there are many form, as long as completing heat exchange function, it is preferred that intermediate Cooler includes heat-dissipating pipe.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art For personnel, under the premise of not departing from principle described in the utility model, it can also make several improvements and retouch, these improvement It also should be regarded as the protection scope of the utility model with retouching.
