A ship exhaust gas waste heat recovery system with secondary recovery function

Abstract

The invention discloses a ship exhaust gas waste heat recovery system with a secondary recovery function and relates to the technical field of ship exhaust gas recovery. The system comprises a bottomplate and an exhaust gas tube; supporting plates are fixedly connected on the two sides of the top of the bottom plate; a first fixed plate and a second fixed plate are fixedly connected to the bottoms and the tops, between the opposite sides, of the two supporting plates correspondingly; a temperature difference power generator is arranged on the surface of the bottom plate in a penetrating mode;one side of the temperature difference power generator communicates with one end of the exhaust gas tube; and a first water storage tank and a second water storage tank are fixedly connected with thetwo sides of the top of the first fixed plate from left to right. The invention relates to the technical field of ship exhaust gas recovery. Through the ship exhaust gas waste heat recovery system with the secondary recovery function, exhaust gas can be secondarily recycled, the utilization rate of waste heat in the exhaust gas is increased, the practicability of the system is improved, rust scale and deposits on the inner walls of a first tube, a first heat exchange tube, a second heat exchange tube and a second tube can be removed, and the situation that impurities are accumulated for a long time, and consequently the heat exchange effect is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of ship waste gas recovery, in particular to a ship waste gas waste heat recovery system with secondary recovery function. Background technique [0002] Ship pollution mainly refers to the pollution caused by ships to the surrounding water environment and atmospheric environment during the process of sailing, berthing in ports, and loading and unloading cargo. The main pollutants are oily sewage, domestic sewage, and ship garbage. In addition, dust, Chemicals, exhaust fumes, etc., but overall less impact on the environment. The main convention for air pollution from ships is MARPOL MARPOL is Annex VII of the International Convention for the Prevention of Pollution from Ships. "The new ship Energy Efficiency Design Index (EEDI) formula is likely to be officially approved at the 59th meeting of the International Maritime Organization (IMO) Marine Environment Protection Committee (MEPC) held in July 2009. EEDI...
