Problems solved by technology
[0005] The method of applying ice to keep fresh has the disadvantages of consuming a large amount of fresh water and energy, poor operation flexibility, and poor fresh-keeping timeliness. The cost of purchasing ice for a 100-ton fishing boat is about 50,000 to 100,000 yuan per year. The cost has risen significantly, and it can no longer meet the requirements of distant water fishery and fresh-keeping time

The invention discloses a power turbine compression refrigeration device for recycling waste heat of exhaust gas of a diesel main engine for a fishing boat and relates to the technical field of compression refrigeration. One end of the diesel main engine of the power turbine compression refrigeration device is connected with an intercooler, and the other end of the diesel main engine is connected with a main engine rear exhaust pipe. The main engine rear exhaust pipe is connected with a turbocharger which is also connected with the intercooler. The turbocharger is connected with a gas intake pipe and a control valve II. The control valve II is connected with a power turbine compression refrigeration system which is connected with a heat exchanger. A control valve I and the turbocharger are arranged in parallel. A control valve III and the power turbine compression refrigeration system are arranged in parallel. The power turbine compression refrigeration device has the beneficial effects that the waste heat of the exhaust gas of the diesel engine can be fully used, energy of the waste gas of the diesel main engine is effectively recycled, and extra refrigeration power is output under the condition that the power of the main engine is not influenced; and after a diesel main engine turbocharger system and the power turbine compression refrigeration system operate in a combined mode, the effective efficiency of the engine can be improved, and the fuel utilization rate can be increased.
Description
technical field [0001] The invention relates to the technical field of compression refrigeration, in particular to a power turbine compression refrigeration device for recovering exhaust waste heat of a diesel main engine used for fishing vessels. Background technique [0002] In recent years, my country's fishery development trend is good. According to data from the Fisheries Bureau of the Ministry of Agriculture of my country, as of the end of 2014, the total number of fishing boats was 1.0654 million, with a total tonnage of 10.7043 million tons, including 686,800 motorized fishing boats, with a total tonnage of 10.2144 million tons; and 378,600 non-motorized fishing boats, with a total tonnage of 489,900 tons. The main power of the diesel engine for fishing boats is very large, generally above 400kw, and the exhaust heat is considerable. Only about 25%-40% of the heat generated by the combustion of fuel oil is discharged into the atmosphere, and there is a large space fo...
