Injection type automatic cascade refrigeration system for tuna fishing boat residual heat recovery

摘要

[PROBLEMS] To improve energy efficiency and reduce emissions on the premise of improving the combustion utilization rate, recovering the exhaust of a fishing boat's diesel engine, improving the performance of the injection refrigeration system, and satisfying the requirement of cryogenic cryopreservation of the fishing boat A jet-type automatic cascade refrigeration system for recovering residual heat from tuna fishing boats. An injection device, a condenser, a gas-liquid separator, a high-temperature level filtration and drying device, a high-temperature level throttle, an evaporation condenser, a low-temperature level filtration and drying device, a low-temperature level throttle, and an evaporator. , Regenerator 10, low temperature level electric control valve 11, high temperature level electric control valve 12, exhaust drive supercharger 13, circulation pump 14, generator 15, diesel engine 16, generator 17 In the injection type automatic cascade refrigeration apparatus, an injection device is provided between the evaporation condenser and the condenser, and an exhaust driving supercharger is provided between the injection device and the evaporation condenser.
