高温下使用板式换热器要注意些什么?
板式(shi)(shi)换热(re)器(qi)具有高效节能、结构紧凑、容易清洗拆装方便、使(shi)用时间长(zhang)、适(shi)应性强、不串液等特点(dian),下面小编来给大家介绍一下高温(wen)下使(shi)用板式(shi)(shi)换热(re)器(qi)的注意事项(xiang)有哪些(xie)?
板(ban)式(shi)换(huan)(huan)(huan)热(re)(re)器(qi)在高温(wen)下使用(yong)(yong)需要注(zhu)意的(de)情况(kuang):板(ban)式(shi)换(huan)(huan)(huan)热(re)(re)器(qi)是根(gen)据换(huan)(huan)(huan)热(re)(re)面积的(de)大小把(ba)相应的(de)半片(pian)(pian)数量(liang)用(yong)(yong)拉紧(jin)螺(luo)栓固(gu)定的(de),在每一片(pian)(pian)半片(pian)(pian)之间(jian)用(yong)(yong)密封(feng)胶垫把(ba)板(ban)片(pian)(pian)隔开(kai),使板(ban)片(pian)(pian)与半片(pian)(pian)之间(jian)留有(you)间(jian)隙来(lai)完(wan)成(cheng)两种介(jie)质的(de)热(re)(re)量(liang)交换(huan)(huan)(huan),在固(gu)定前要用(yong)(yong)压(ya)力(li)机(ji)将板(ban)片(pian)(pian)压(ya)紧(jin),然(ran)后再用(yong)(yong)拉紧(jin)螺(luo)栓和螺(luo)母固(gu)定好,在这(zhei)情况(kuang)下要保证板(ban)式(shi)换(huan)(huan)(huan)热(re)(re)器(qi)不会变形(xing)和泄漏。当液体流入板(ban)式(shi)换(huan)(huan)(huan)热(re)(re)器(qi)内时,在两种高温(wen)介(jie)质的(de)流动下压(ya)力(li)由小逐渐(jian)的(de)变大,这(zhei)时要保证其压(ya)力(li)小于(yu)板(ban)式(shi)换(huan)(huan)(huan)热(re)(re)器(qi)的(de)额定承压(ya)能力(li)。
板式换热器(qi)已被应用于冶金、矿山、石油(you)、化(hua)工、电力、医(yi)药、食品、化(hua)纤(xian)、造纸(zhi)、轻纺(fang)、船舶、供(gong)热等部(bu)门,可用于加热、冷(leng)却、蒸发、冷(leng)凝(ning)、杀菌消(xiao)毒(du)、余热回收等情况。
