Problems solved by technology
However, with the development of ships in the direction of large-scale, high-speed, and automation, less and less steam is used for the crew's daily life, which makes the utilization of exhaust heat from marine diesel engines more and more insufficient and unreasonable
In addition, the energy in the jacket water (temperature is about 80-90°C) of marine diesel engine is not effectively utilized, which causes a lot of energy waste

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-3 As shown, when the present invention works, the marine diesel engine 1 exhaust gas is discharged from the marine diesel engine 1, first passes through the turbocharger 2 to perform work, and then enters the organic Rankine cycle unit 11 through the control of the bypass baffle V1 / V2 / V3. In the Rankine cycle unit 11 , part of the energy of the exhaust gas of the marine diesel engine 1 is converted into electrical energy and stored in the storage battery 9 . The storage battery 9 directly supplies power to the electrolysis unit 8, and at the same time also supplies power to the lye supply pump 5; the chlorine gas produced by the anode of the electrolysis unit 8 is supplied to the ballast tank of the ship through the valve V8, and is used to kill microorganisms in the ballast water; the electrolysis unit 8 The hydrogen produced by the cathode can be fed...

The invention discloses a ship diesel engine exhaust gas treatment and utilization device and a working method thereof; the device comprises an exhaust gas treatment system, an exhaust gas waste heat power generation system and an electrolysis system; the exhaust gas waste heat power generation system comprises organic Rankine cycle unit, an electric generator and a storage battery; the electrolysis system comprises an electrolysis unit, an alkaline liquor cabinet, a mixing cabinet and an alkaline liquor supplying pump; the exhaust gas treatment system comprises a flue gas heat exchanger, a washing tower, a sea water spraying device and an aeration tank. Based on organic Rankine cycle, the ship diesel engine exhaust gas waste heat is used for generating the power, and the generated electric energy is directly used for desulfuration for the ship diesel engine exhaust gas. The electric energy used by the electrolysis unit is the electric energy generated by the ship exhaust gas waste heat, no additional electric energy is inputted, the ship exhaust gas processing cost is greatly saved, and the waste heat of the exhaust gas is used for processing the exhaust gas of diesel engine, and on-line treatment is realized.
Description
technical field [0001] The invention relates to a waste heat utilization technology of ship waste gas, in particular to a ship diesel engine waste gas treatment and utilization device and its working method. Background technique [0002] According to IMO (International Maritime Organization) data, the SO emitted by ships every year 2 Reached 6.34 million tons, accounting for about 4% of world emissions. The air pollution caused by ships has reached a level that cannot be ignored. In some places where ports and straits are densely populated, ship exhaust gas has become the main source of local air pollution. In September 1997, the International Maritime Organization passed Annex VI of the MARRPOL Convention (International Convention for the Prevention of Pollution from Ships), which came into effect in my country on August 23, 2006. 2 emissions are strictly limited. In 2011, the 58th meeting of MPEC (Marine Environment and Protection Committee) passed the amendment to Anne...
