2022年3月湖北荊門客戶訂制一批用于蒸(zheng)氨塔DJ-5型塔板不銹鋼塔內件產品，蒸(zheng)氨塔是使溶解(jie)(jie)于循(xun)環水中的氨氣(qi)釋放(fang)(fang)的解(jie)(jie)吸塔，從屬于解(jie)(jie)吸裝(zhuang)置，是使溶解(jie)(jie)于循(xun)環水中的氨氣(qi)通過熱(re)載體的傳熱(re)而(er)揮(hui)發釋放(fang)(fang)出來的操作設備。

蒸(zheng)(zheng)氨塔(ta)工作(zuo)原理為：采用(yong)一(yi)般的載熱體水蒸(zheng)(zheng)汽(qi)作(zuo)為加(jia)熱劑(ji)，使循(xun)環水液(ye)面上氨氣的平衡(heng)蒸(zheng)(zheng)汽(qi)壓(ya)大于熱載體中氨氣的分(fen)壓(ya)，汽(qi)液(ye)兩相逆(ni)流接觸 ，進(jin)行傳(chuan)質(zhi)傳(chuan)熱，從而(er)使氨氣逐漸從循(xun)環水中釋放出來 ，在塔(ta)頂(ding)得到(dao)氨蒸(zheng)(zheng)汽(qi)與水蒸(zheng)(zheng)汽(qi)的混合(he)物，在塔(ta)底得到(dao)較純凈的循(xun)環水。總之，加(jia)堿源的目的是(shi)使固(gu)定銨鹽(yan)轉化為揮發(fa)銨鹽(yan)。

客(ke)戶通(tong)過項目工況數據表描述，我公(gong)司進行設計選(xuan)型，建(jian)議客(ke)戶使(shi)用(yong)(yong)我公(gong)司研發的DJ-5型塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)（固(gu)定(ding)閥(fa)塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)），DJ-5型塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)采用(yong)(yong)新(xin)型固(gu)定(ding)閥(fa)作為鼓泡組件，降(jiang)(jiang)液(ye)管(guan)型式(shi)可(ke)沿用(yong)(yong)傳統(tong)的弓(gong)形(xing)(xing)降(jiang)(jiang)液(ye)管(guan)結構，也可(ke)以(yi)采用(yong)(yong)矩形(xing)(xing)懸掛式(shi)降(jiang)(jiang)液(ye)管(guan)。新(xin)型固(gu)定(ding)閥(fa)塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)較好地綜合(he)了篩孔塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)和浮閥(fa)塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)的優點，克(ke)服了浮閥(fa)塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)制(zhi)造成本高、易堵塞(sai)、浮閥(fa)容易吹(chui)掉(diao)或卡住(zhu)和篩孔塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)霧沫(mo)夾帶量大、而塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)效率和普(pu)通(tong)浮閥(fa)相當，可(ke)一(yi)對一(yi)替換浮閥(fa)塔(ta)(ta)(ta)(ta)板(ban)(ban)(ban)。
