The invention discloses an II type sterling generator system using ship waste heat. The system comprises a ship smoke discharge system, an II type sterling engine body, a working medium supply and recovery system, a power generation system, a starting system and a control system for controlling the operation of the whole system, wherein the II type sterling engine body comprises a first sterling engine body, a second sterling engine body, a main crankshaft and a flywheel. A high-efficiency waste heat absorber of the II type sterling engine is mounted behind a ship waste gas boiler for further absorbing the ship smoke discharge heat to generate electricity so as to reduce the greenhouse effect caused by the ship smoke discharge. The II type sterling engine is designed with two parallel high-temperature and low-temperature heat regenerators having one-way valves. When helium is transferred by a cold cylinder to a heater, the high-temperature heat regenerator works; when the helium is transferred by a hot cylinder to the cold cylinder through the heater, the low-temperature heat regenerator works; and a PLC controls one of the high-temperature and low-temperature heat regenerators to work, so that the efficiency of the sterling engine is improved.
Description
technical field [0001] The invention relates to the technical field of energy recovery and utilization, in particular to a Π-type Stirling generator system for ship waste heat utilization. Background technique [0002] Only a small part of the heat generated by the fuel combustion of the main engine of the ship does work, part of the remaining heat is taken away by the cooling system, and the other part is released into the atmosphere through exhaust. The exhaust loss accounts for about 40% of the total energy. Ships are equipped with exhaust gas boilers for waste heat utilization. The exhaust gas boiler exhausts at about 100-300°C, and the seawater temperature around the ship does not exceed 35°C. This constitutes a huge temperature difference energy system. The Stirling Engine is an external The combustion (heating) closed piston heat engine has the advantages of wide fuel source, high efficiency, low pollution, low noise and convenient maintenance. have important meaning...
