Fishing boat waste heat recycling system and method

Abstract

The invention discloses a fishing boat waste heat recycling system and method. The system comprises a temperature difference power generation device, an absorption refrigerator, a solar heat collector, an electric auxiliary heating device, a control unit and a detection unit, wherein the detection unit is used for detecting the external environment and the temperature of a water outlet of the solar heat collector and sending data to the control unit; and the control unit coordinates the temperature difference power generation device, the absorption refrigerator, the solar heat collector and the electric auxiliary heating device to operate mutually according to the data sent by the detection unit. System operation schemes under different environment conditions are provided, and the comprehensive energy utilization mode of summer waste heat cooling, winter waste heat heating, four-season normalized temperature difference power generation and refrigeration is achieved, so that the energyutilization rate is increased to the maximum extent, fuel consumption and tail gas emission are reduced, and economic benefits and environmental benefits are remarkable. The cost can be recovered, thesaved fuel oil can continuously create economic benefits for fishermen, and good application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of ship energy recovery, in particular to a system and method for recycling waste heat from fishing boats. Background technique [0002] my country's fishing boats are huge, with nearly one million fishing boats, ranking first in the world. Among them, the number of motorized fishing boats accounted for more than 60%, with diesel as the main energy source. However, the energy utilization efficiency of diesel is not ideal. Only 54% of the energy of the diesel engine is used to propel the fishing boat and the operation of fishing machinery, and 39% of the energy is discharged with cooling water and exhaust gas. The total amount of waste heat wasted every year is huge. The waste heat of the exhaust gas discharged from the diesel engine of the fishing boat can reach 350-410°C. The energy taste is good, and the waste heat has considerable recovery value. consumption. [0003] The pollutants emitted by marine d...
