結(jie)構

噴(pen)(pen)淋(lin)塔(ta)內(nei)(nei)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)作為氣(qi)(qi)(qi)液兩(liang)(liang)相間接(jie)觸構(gou)件的(de)傳質(zhi)設(she)備(bei)。填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)塔(ta)底部裝有(you)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)支承(cheng)板(ban)，填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)以亂堆方式(shi)放置在支承(cheng)板(ban)上(shang)(shang)。填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)的(de)上(shang)(shang)方安裝填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)壓(ya)板(ban)，以防被上(shang)(shang)升(sheng)氣(qi)(qi)(qi)流(liu)(liu)吹動(dong)。噴(pen)(pen)淋(lin)塔(ta)噴(pen)(pen)淋(lin)液從塔(ta)頂經(jing)液體(ti)分(fen)布(bu)器(qi)噴(pen)(pen)淋(lin)到(dao)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)上(shang)(shang)，并(bing)沿填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)表(biao)(biao)面流(liu)(liu)下。氣(qi)(qi)(qi)體(ti)從塔(ta)底送入，經(jing)氣(qi)(qi)(qi)體(ti)分(fen)布(bu)裝置分(fen)布(bu)后，與液體(ti)呈逆流(liu)(liu)連續通(tong)過填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)的(de)空隙(xi)，在填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)表(biao)(biao)面上(shang)(shang)，氣(qi)(qi)(qi)液兩(liang)(liang)相密(mi)切接(jie)觸進行傳質(zhi)。 當(dang)液體(ti)沿填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)向下流(liu)(liu)動(dong)時(shi)，有(you)時(shi)會出現壁流(liu)(liu)現象，壁流(liu)(liu)效應造成氣(qi)(qi)(qi)液兩(liang)(liang)相在填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)中分(fen)布(bu)不均(jun)，從而使傳質(zhi)效率下降。因(yin)此，噴(pen)(pen)淋(lin)塔(ta)內(nei)(nei)的(de)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)層(ceng)分(fen)為兩(liang)(liang)段，中間設(she)置再(zai)分(fen)布(bu)裝置，經(jing)重新分(fen)布(bu)后噴(pen)(pen)淋(lin)到(dao)下層(ceng)填(tian)(tian)(tian)(tian)(tian)料(liao)(liao)(liao)(liao)上(shang)(shang)。  

適用注(zhu)意事(shi)項(xiang)

1、循環水(shui)(shui)量(liang)(liang)的調節：由(you)噴淋塔供水(shui)(shui)泵來決(jue)定，當運行一(yi)臺(tai)鍋爐時(shi)開一(yi)臺(tai)即(ji)可(ke)，當冬季兩(liang)臺(tai)或三臺(tai)同時(shi)運行時(shi)，將兩(liang)臺(tai)水(shui)(shui)泵全(quan)部打開，泥漿(jiang)泵其流量(liang)(liang)應根(gen)據循環泵的流量(liang)(liang)來調節，使其相等即(ji)可(ke)。

 2、噴淋塔內加(jia)(jia)(jia)藥(yao)池(chi)內的加(jia)(jia)(jia)藥(yao)量：當運行一臺(tai)鍋爐時(shi)，加(jia)(jia)(jia)入堿2袋，加(jia)(jia)(jia)入熟石灰5袋，如冬季運行兩臺(tai)或三(san)臺(tai)時(shi)，可按(an)相應倍數增加(jia)(jia)(jia)藥(yao)量。

  3噴淋塔沉淀(dian)池要經(jing)常清理，夏天(tian)一周清理一次，冬季(ji)三天(tian)清理一次。

4、灰水(shui)分離器排污(wu)時，每班排放一次(ci)，要分別打開排污(wu)閥(fa)門，直到(dao)有清水(shui)排出為止(zhi)。

5、以上各轉動部件要(yao)經常檢查、注油，發現(xian)故障要(yao)及時(shi)排除，以保證噴淋塔脫硫效果。

6、在上(shang)、下樓梯(ti)加(jia)藥(yao)時要(yao)注意，要(yao)有自主保安，相互保安意識(shi)。

7、工作完畢要及時清理好衛生，做到人走(zou)場地清。
