【摘要】：為了在鹽水分離領(lǐng)域更高效地利用太陽能、地熱及發(fā)動機余熱等低溫熱源,參考傳統(tǒng)海水淡化裝置,設(shè)計一種將噴霧閃蒸、熱管傳熱與固體吸附耦合集成的新型吸附式鹽溶液水分離裝置,并對氯化鈉含量為3%的鹽溶液進行水分離試驗,結(jié)果表明:溶液經(jīng)霧化閃蒸后溫度驟降,接觸熱管冷端后吸收大量熱量蒸發(fā),該裝置可利用40~100℃的低溫熱源,單級可分離鹽溶液中18%~60%的水分;熱源溫度是影響分離率的關(guān)鍵因素;吸附劑的吸附作用在相同熱源溫度下可大幅降低閃蒸室蒸發(fā)壓力,提高過熱度;整個吸附及脫附周期內(nèi)壓力呈規(guī)律性變化,不僅受吸附床切換而驟變,還受閃蒸室熱源與吸附劑內(nèi)冷卻水溫度的變化影響;降低冷卻水溫度可明顯降低蒸發(fā)室平衡壓力,保證蒸發(fā)器內(nèi)液滴持續(xù)蒸發(fā),提高分離率。
[Abstract]:In order to make more efficient use of low temperature heat sources such as solar energy, geothermal energy and engine waste heat in the field of brine separation, a spray flash was designed with reference to the traditional seawater desalination device. A new type of adsorbed salt solution water separation device, which is coupled with heat transfer and solid adsorption, is developed. The water separation test of salt solution with sodium chloride content of 3% is carried out. The results show that the temperature of the solution drops sharply after atomization and flash evaporation. After contact with the cold end of the heat pipe, a large amount of heat evaporation is absorbed. The apparatus can use a low temperature heat source of 40 ~ 100 鈩，
