【摘要】：隨著環(huán)境的污染加劇和能源供應(yīng)波動(dòng)給航運(yùn)業(yè)造成的多次沖擊,提高船舶的能源利用率已經(jīng)成為人們研究的熱點(diǎn)。溫差發(fā)電作為一種熱電轉(zhuǎn)換技術(shù),在余熱利用方面有其獨(dú)特的優(yōu)勢(shì)。通過溫差發(fā)電技術(shù)對(duì)船舶余熱進(jìn)行回收利用,既能提高燃油利用率,又可減少熱量的散失和污染物的排放。為此,本文針對(duì)船舶余熱特點(diǎn),對(duì)以船舶余熱為熱源的溫差發(fā)電開展研究,主要研究工作包括:首先,針對(duì)某遠(yuǎn)洋運(yùn)輸公司的巴拿馬型、阿芙拉型、蘇伊士型以及VLCC四種船型的40余艘油輪,分別選取了實(shí)船運(yùn)營數(shù)據(jù)進(jìn)行了計(jì)算和分析,并對(duì)船舶柴油機(jī)煙氣、蒸汽和缸套水等余熱利用方案進(jìn)行了研究,為船舶余熱溫差發(fā)電裝置的研究奠定了基礎(chǔ)。其次,搭建了船舶余熱溫差發(fā)電實(shí)驗(yàn)裝置,分別開展了接觸熱阻、接觸壓力、熱端溫度、負(fù)載阻值和發(fā)電片連接方式等因素對(duì)溫差發(fā)電裝置影響的實(shí)驗(yàn),得出各工況下的伏安特性、輸出功率、開路電壓和系統(tǒng)效率。通過實(shí)驗(yàn)研究發(fā)現(xiàn):1)當(dāng)熱端溫度分別為80℃、85℃、90℃和95℃時(shí),采用導(dǎo)熱硅脂為熱交界面材料時(shí)比采用石墨導(dǎo)熱片時(shí)最大輸出功率分別提高103%、107%、105%、和107%;2)單片TEP126型號(hào)在熱端溫度分別為80℃、85℃、90℃和95℃時(shí)的最大輸出功率分別為0.462W、0.555W、0.658W和0.766W,在熱端溫度分別為100℃、110℃、120℃和130℃時(shí),最大輸出功率分別為0.765W、1.005W、1.273W 和 1.568W;3)在熱端溫度分別為 80℃、85℃、90℃和 95℃時(shí),16片TEP126溫差發(fā)電片所得到最大輸出功率分別為6.187W、7.478W、8.873W和10.388W,系統(tǒng)效率分別為 1.4%、1.53%、1.62%和 1.77%。最后,依據(jù)大連海事大學(xué)智能機(jī)艙的主機(jī)缸套水系統(tǒng),對(duì)船用柴油機(jī)缸套水余熱溫差發(fā)電裝置進(jìn)行了設(shè)計(jì)開發(fā)。其中,對(duì)溫差發(fā)電裝置換熱器的內(nèi)部結(jié)構(gòu)和裝置的緊固方式進(jìn)行了研究,同時(shí)對(duì)實(shí)際布置方案進(jìn)行了研究。經(jīng)計(jì)算,若缸套水余熱可得到充分回收利用,則可產(chǎn)生最大輸出功率在20.53kW～25.22kW之間。
[Abstract]:With the pollution of the environment and the fluctuation of energy supply causing many impacts to the shipping industry, improving the energy efficiency of ships has become the focus of research. Thermoelectric power generation, as a thermoelectric conversion technology, has its unique advantages in the utilization of residual heat. The recovery and utilization of ship residual heat by thermoelectric technology can not only improve the fuel utilization efficiency, but also reduce the heat loss and pollutant emission. Therefore, according to the characteristics of ship residual heat, this paper studies the thermal power generation with ship waste heat as heat source. The main research work includes: firstly, the Panamanian model, Aphra type of an ocean shipping company, More than 40 oil tankers of Suez type and VLCC ship type were selected to calculate and analyze the operation data of the ship, and the waste heat utilization schemes such as flue gas, steam and liner water of the marine diesel engine were studied. It lays a foundation for the research of ship waste heat differential power generation device. Secondly, the experimental equipment of ship waste heat difference power generation is built, and the influence of contact thermal resistance, contact pressure, hot end temperature, load resistance value and the connection mode of power sheet on the thermal power generation device are carried out respectively. The volt-ampere characteristics, output power, open circuit voltage and system efficiency are obtained. The experimental results show that when the hot end temperature is 80 鈩，
