Embodiment Construction

[0036] Such as Figure 1 to Figure 5 As shown, a ship waste heat recovery two-stage thermoelectric power generation device includes: a flue gas pipeline, a hexahedron structure 17, a thermoelectric power generation mechanism and a cold plate structure.

[0037] The diameter of the flue gas pipeline is the same as the diameter of the smoke exhaust pipe of the ship incinerator, and a section of pipeline is intercepted in the middle of the smoke exhaust pipe of the ship incinerator and replaced with the flue gas pipeline; the front end of the flue gas pipeline is a flue gas inlet 15 , the rear end is a flue gas outlet 16, and the flue gas pipeline is surrounded by the hexahedral structure 17; the material of the flue gas pipeline and the hexahedral structure 17 is metallic copper. In order to achieve optimal heat transfer efficiency and reduce heat loss, copper was selected as the overall material of the device after comprehensive consideration.

[0038] After the ship flue gas ...

Abstract

The invention discloses a two-stage thermoelectric power generation device for ship waste heat recovery and a power generation method. The device comprises a fume pipeline, a hexahedral structure, a thermoelectric power generation mechanism and a cooling plate structure; a section of pipeline is cut from the middle of a ship incinerator exhaust pipe and replaced with the fume pipeline; the front end of the fume pipeline is a fume inlet, the rear end of the fume pipeline is a fume outlet, and the outside of the fume pipeline is wrapped with the hexahedral structure; the thermoelectric power generation mechanism comprises two-stage thermoelectric power generation units; the cooling plate structure comprises two-stage cooling plates; the first-stage thermoelectric power generation unit is tightly close to the outer wall of the hexahedral structure, and the first-stage cooling plate, the second-stage thermoelectric power generation unit and the second-stage cooling plate are arranged on the outside of the first-stage thermoelectric power generation unit sequentially. According to the two-stage thermoelectric power generation device for ship waste heat recovery and the power generationmethod, a way of efficiently recycling ship incinerator high-temperature exhaust gas waste heat in stages and using the waste gas for power generation is provided, the high-temperature exhaust gas waste heat can be directly converted into electric energy, energy gradient utilization is realized, the utilization amount of the waste heat is increased, and the device power is improved.

Description

technical field [0001] The invention relates to the technical field of ship energy saving, in particular to a novel method and device for generating power by recovering high-temperature waste gas waste heat from ships. Background technique [0002] At present, the rapid development of science and technology has accelerated the process of global economic integration. The exchanges and intercommunications between countries in the world have become increasingly frequent, and the volume of foreign trade has increased rapidly. Ships have become one of the main means of transportation for the development of the world economy. and economic prosperity played an extremely important role. [0003] A large number of studies have shown that there are relatively many forms of waste heat generated by marine diesel engines, mainly including waste heat such as smoke exhaust from marine diesel engines, cylinder jacket cooling water, and air coolers. About 50% of the heat energy generated by ...
