Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention relates to a vehicle-mounted heat pump drying system driven by an engine, which comprises a truck engine 2, wherein the truck engine 2 is connected with a gas-water heat exchanger 5 through a pipeline a15 to form a truck engine tail gas waste heat utilization circulating system;
the gas-water heat exchanger 5 is sequentially connected with the liquid-water heat exchanger 3, the high-temperature evaporator 11 and the circulating water pump 6 through a pipeline c17 to form a closed loop, so that a cooling waste heat and tail gas waste heat utilization circulating system of the truck engine is formed;
the liquid-water heat exchanger 3 is sequentially connected with the cooling liquid radiator 4, the cooling liquid circulating pump 1 and the truck engine 2 through a pipeline b16 to form a closed loop, so that a truck engine cooling waste heat utilization circulating system is formed;
the system further comprises a second compressor 12, the second compressor 12 is sequentially connected with the condenser 13, the first throttling mechanism 7, the air side evaporator 8 and the first compressor 9 through a pipeline d18 to form a loop, one end of the high-temperature evaporator 11 is connected between the condenser 13 and the first throttling mechanism 7 through a second throttling mechanism 10, the other end of the high-temperature evaporator 11 is connected between the second compressor 12 and the first compressor 9 through a pipeline e19 to form a heat pump drying system, and the condenser 13 is arranged in the oven;
an output shaft of the truck engine 2 is respectively connected with a first compressor 9 and a second compressor 12 through a planetary gear mechanism;
line b16 is filled with coolant, line c17 is filled with heating medium, and lines d18 and e19 are filled with refrigerant R134 a.
As shown in fig. 2, the planetary gear mechanism includes a main gear 2-1 connected to an output shaft of the truck engine 2, the main gear 2-1 is engaged with a first driven gear 2-2 and a second driven gear 2-3, respectively, an output shaft of the first driven gear 2-2 is connected to the second compressor 12, and an output shaft of the second driven gear 2-3 is connected to the first compressor 9.
The working principle of the engine-driven vehicle-mounted heat pump drying system is as follows:
after a truck arrives at a drying place, agricultural and special products to be dried are placed in a carriage, a truck engine 2 starts to work under the driving of fuel, waste gas discharged by the truck engine 2 transfers heat carried by the waste gas to a heating medium in a pipeline c17 in an air-water heat exchanger 5 and then is discharged, meanwhile, a cooling liquid circulating pump 1 drives low-temperature cooling liquid to enter the truck engine 2 to cool the engine so that the engine works at a proper temperature, the cooling liquid absorbs heat and is heated, then the cooling liquid enters a liquid-water heat exchanger 3 to release the heat to a pipeline c17 and then flows into a cooling liquid radiator 4, and the temperature of the cooling liquid in the cooling liquid radiator 4 is reduced again and then is driven by the cooling liquid circulating pump 1 to enter the truck engine 2 to cool the engine.
The heat medium in the pipeline c17, driven by the circulating water pump 6, first absorbs the waste heat carried by the engine exhaust gas in the gas-water heat exchanger 5, then heats up, then flows to the liquid-water heat exchanger 3 to absorb the engine cooling waste heat, and then heats up again, and then flows to the high-temperature evaporator 11 to release heat to the refrigerant, and then continues to absorb and release heat under the drive of the circulating water pump 6.
An output shaft of a truck engine 2 is connected with a main gear 2-1, the main gear 2-1 is respectively meshed with a driven gear I2-2 and a driven gear II 2-3, an output shaft of the driven gear I2-2 drives a second compressor 12 to work, and an output shaft of the driven gear II 2-3 drives a first compressor 9 to work. Therefore, when the fuel-driven truck engine 2 is operated, the first compressor 9 and the second compressor 12 are simultaneously operated.
The gaseous high boiling point refrigerant discharged from the second compressor 12 is condensed into saturated or supercooled refrigerant liquid in the condenser 13, and at the same time, heat is released to dry the agricultural and special products, a part of the saturated or supercooled refrigerant liquid enters the first throttling mechanism 7 to be throttled to form low-pressure gas-liquid two-phase refrigerant fluid, the low-pressure gas-liquid two-phase refrigerant fluid then enters the air-side evaporator 8 to absorb heat in the air to become low-pressure saturated or superheated refrigerant vapor, and the saturated or superheated refrigerant vapor is sucked by the first compressor 9 and becomes medium-pressure superheated refrigerant vapor after being compressed.
The other part of the saturated or subcooled refrigerant liquid flowing out of the condenser 13 enters the second throttling mechanism 10 for throttling to form medium-pressure gas-liquid two-phase refrigerant fluid, and the medium-pressure gas-liquid two-phase refrigerant fluid then enters the heat carried by the heating medium in the pipeline c17 of the high-temperature evaporator 11 to become medium-pressure saturated or superheated refrigerant vapor.
The medium pressure superheated or saturated refrigerant vapor discharged from the first compressor 9 is mixed with the medium pressure saturated or superheated refrigerant vapor discharged from the high temperature evaporator 11, sucked by the second compressor 12, compressed to be superheated refrigerant vapor, and discharged again to the condenser 13 to release heat and dry the agricultural and specialty products.
Through the mode, the drying system of the engine-driven vehicle-mounted heat pump can firstly dry the farm product at the place nearest to the farm product along with the truck, and the farm product is lighter in weight, smaller in volume and easier to store after being dried, so that the quality of the farm product is higher, and meanwhile, more farm products are transported in the same space, and the transportation cost is reduced; the invention has the advantages that the freight car fuel is completely used as the driving energy, the drying operation can be carried out in the region where the power grid is not popularized, the dependence of the heat pump dryer on the power grid is eliminated, the energy released by the fuel can be effectively utilized in the final drying process, the heat can be absorbed from the air, and the energy-saving and environment-friendly effects are obvious.
