【摘要】：對(duì)一種串列式多級(jí)加熱增濕除濕型太陽能海水淡化裝置進(jìn)行了穩(wěn)態(tài)實(shí)驗(yàn)測(cè)試,介紹了三級(jí)裝置的結(jié)構(gòu)和工作過程。選用多孔球作為填充材料來提升蒸發(fā)器的傳質(zhì)過程。通過改變不同噴淋溫度、進(jìn)水流量和空氣流率等控制參數(shù),研究了不同運(yùn)行參數(shù)下的系統(tǒng)性能。實(shí)驗(yàn)結(jié)果表明,在實(shí)驗(yàn)給定參數(shù)范圍內(nèi),隨著進(jìn)水流量和噴淋溫度的增加產(chǎn)水量增加。當(dāng)運(yùn)行溫度90℃、進(jìn)水流量為2 t/h,產(chǎn)水量達(dá)到182.47 kg/h。在運(yùn)行溫度達(dá)到85℃時(shí),性能系數(shù)能達(dá)到最大值2.65。單位裝置體積的產(chǎn)水量達(dá)到22kg/(m~3h)。單級(jí)加熱的性能系數(shù)最高達(dá)2.27。通過實(shí)驗(yàn)發(fā)現(xiàn),串列式多級(jí)加熱型增除濕海水淡化技術(shù)仍有很大的提升空間。
[Abstract]:A series of multi-stage heating and dehumidifying solar desalination system for seawater desalination was tested in steady state. The structure and working process of the three-stage plant were introduced. The mass transfer process of evaporator was enhanced by using porous ball as filling material. The control parameters such as different spray temperature, influent flow rate and air flow rate were changed. The performance of the system under different operating parameters is studied. The experimental results show that the water production increases with the increase of influent flow rate and spray temperature in the range of given experimental parameters, and the operating temperature is 90 鈩，
