2024年12月16日，國家知識產權局信息顯示，浙江大通清潔能源裝備制造有限公司取得一項名為“單罐熔鹽儲熱蒸發器的換熱系統”的專利，授權公告號CN 222143860 U，申請日期為2024年4月。

專(zhuan)利(li)摘要顯示，本(ben)實用新(xin)型(xing)公開了一種單罐熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)儲熱(re)(re)(re)(re)蒸(zheng)發(fa)器(qi)的(de)(de)換熱(re)(re)(re)(re)系統(tong)，包(bao)括設(she)于(yu)熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)罐內(nei)部的(de)(de)換熱(re)(re)(re)(re)管(guan)(guan)和一組沿周向均勻間隔分(fen)布的(de)(de)電(dian)加熱(re)(re)(re)(re)器(qi)；所述(shu)電(dian)加熱(re)(re)(re)(re)器(qi)環繞于(yu)換熱(re)(re)(re)(re)管(guan)(guan)的(de)(de)外側(ce)，用于(yu)對熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)罐中的(de)(de)熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)進行(xing)加熱(re)(re)(re)(re)；所述(shu)換熱(re)(re)(re)(re)管(guan)(guan)和電(dian)加熱(re)(re)(re)(re)器(qi)之間設(she)有導(dao)(dao)流圍(wei)(wei)欄(lan)；所述(shu)導(dao)(dao)流圍(wei)(wei)欄(lan)上下開口(kou)(kou)，并包(bao)圍(wei)(wei)于(yu)換熱(re)(re)(re)(re)管(guan)(guan)的(de)(de)外側(ce)；所述(shu)導(dao)(dao)流圍(wei)(wei)欄(lan)內(nei)部的(de)(de)空間為(wei)低溫(wen)區，所述(shu)熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)罐和導(dao)(dao)流圍(wei)(wei)欄(lan)之間的(de)(de)空間為(wei)高溫(wen)區；所述(shu)電(dian)加熱(re)(re)(re)(re)器(qi)位于(yu)高溫(wen)區內(nei)，所述(shu)換熱(re)(re)(re)(re)管(guan)(guan)位于(yu)低溫(wen)區內(nei)；所述(shu)換熱(re)(re)(re)(re)管(guan)(guan)的(de)(de)進水口(kou)(kou)通過(guo)進水管(guan)(guan)道(dao)連接至給水泵(beng)的(de)(de)出(chu)(chu)水口(kou)(kou)，所述(shu)給水泵(beng)的(de)(de)進水口(kou)(kou)連接至供水裝置的(de)(de)出(chu)(chu)水口(kou)(kou)。在熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)放熱(re)(re)(re)(re)時，可以利(li)用冷熱(re)(re)(re)(re)熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)的(de)(de)密度差形成壓力(li)差，促(cu)使熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)流動，實現(xian)熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)在熔(rong)(rong)(rong)(rong)鹽(yan)(yan)(yan)罐內(nei)部的(de)(de)自然(ran)循環。
