電蒸(zheng)汽(qi)(qi)發生(sheng)器廣(guang)活當(dang)泛(fan)應用(yong)于文明(ming)的(de)生(sheng)活中,主(zhu)要應用(yong)于生(sheng)物制藥、化工反應、實驗研究、食品加工、包裝(zhuang)機械(xie)、服裝(zhuang)整燙洗(xi)滌漂染、高溫清洗(xi)、混(hun)凝(ning)土蒸(zheng)汽(qi)(qi)養(yang)護等(deng)方面。但對于蒸(zheng)汽(qi)(qi)發生(sheng)器的(de)基本(ben)構成以及(ji)工作(zuo)原理又是(shi)怎么(me)樣的(de)呢,接下來(lai),廠家就帶你了解一下!
電蒸汽發(fa)生器主要由爐膽(dan)、自控(kong)系(xi)統(tong)(tong)、加(jia)熱(re)系(xi)統(tong)(tong)、供水系(xi)統(tong)(tong)和(he)保護系(xi)統(tong)(tong)等(deng)構成。
1.爐膽一(yi)(yi)般是采用(yong)(yong)鍋爐專用(yong)(yong)的無縫鋼管(guan)制成(cheng),呈細長直立式,電加(jia)熱(re)系統采用(yong)(yong)的電熱(re)管(guan)大(da)多由1根或多根不銹鋼電熱(re)管(guan)彎曲組合而成(cheng),其額定電率一(yi)(yi)般為(wei)交流380伏(fu)或220伏(fu),而其表面負荷一(yi)(yi)般在20瓦/平方厘米左右。由于(yu)發生(sheng)器(qi)正常工(gong)作(zuo)時,有較高(gao)的壓(ya)力和溫度,保(bao)護系統可(ke)使其在長期運行中、可(ke)靠、。一(yi)(yi)般都采用(yong)(yong)高(gao)強度銅合金制作(zuo)的閥(fa)、單(dan)向閥(fa)、排(pai)氣(qi)閥(fa)實施三級(ji)保(bao)護。部分(fen)產品還(huan)增加(jia)了(le)水位玻璃管(guan)保(bao)護裝置,增加(jia)了(le)使用(yong)(yong)者的感(gan)。
2.供水(shui)(shui)系(xi)統是(shi)全自(zi)動蒸(zheng)汽發生(sheng)器(qi)的(de)(de)咽喉,源源不斷的(de)(de)為客戶(hu)提供干燥蒸(zheng)汽。當(dang)水(shui)(shui)源進(jin)入(ru)(ru)水(shui)(shui)箱后(hou),啟動電源按鈕,經由自(zi)控信號的(de)(de)驅動,耐高(gao)溫電磁閥(fa)打開,水(shui)(shui)泵(beng)工作,通過(guo)單(dan)向閥(fa)注入(ru)(ru)爐膽。當(dang)電磁閥(fa)、單(dan)向閥(fa)堵塞或(huo)損壞,供水(shui)(shui)達到壓(ya)力(li)時將經過(guo)過(guo)壓(ya)閥(fa)溢水(shui)(shui)回到水(shui)(shui)箱,從而保(bao)護水(shui)(shui)泵(beng)。當(dang)水(shui)(shui)箱斷水(shui)(shui)或(huo)水(shui)(shui)泵(beng)管路內有(you)殘余空(kong)(kong)氣(qi)時,只(zhi)進(jin)空(kong)(kong)氣(qi)不進(jin)水(shui)(shui),只(zhi)要通過(guo)排氣(qi)閥(fa)迅(xun)速排氣(qi),待(dai)有(you)水(shui)(shui)噴(pen)出,關閉排氣(qi)閥(fa),水(shui)(shui)泵(beng)就能正常工作。供水(shui)(shui)系(xi)統中的(de)(de)是(shi)水(shui)(shui)泵(beng),大多(duo)采(cai)用較(jiao)高(gao)壓(ya)力(li)和較(jiao)大流量的(de)(de)多(duo)級旋渦泵(beng),小部分采(cai)用膜片泵(beng)或(huo)葉片泵(beng)。
3.液(ye)位控制(zhi)(zhi)器(qi)是發(fa)生器(qi)自控系統的(de)中樞系統,分為電(dian)(dian)子式和機械式兩大類,電(dian)(dian)子式液(ye)位控制(zhi)(zhi)器(qi)是通過(guo)3根高低不一的(de)電(dian)(dian)極(ji)探棒控制(zhi)(zhi)液(ye)面(即水(shui)位的(de)高低差),從而(er)控制(zhi)(zhi)水(shui)泵的(de)供(gong)水(shui)量和爐膽電(dian)(dian)熱系統的(de)加熱時間(jian),工作壓力穩(wen)定(ding),應(ying)用范圍比較廣泛。機械式液(ye)位控制(zhi)(zhi)器(qi)采用不銹(xiu)鋼浮球式,適用于爐膽容積較大的(de)發(fa)生器(qi),工作壓力不太穩(wen)定(ding),但(dan)便于拆(chai)洗、保養和維修。
電蒸汽發生器的工(gong)作原理
在(zai)水(shui)(shui)汽(qi)系(xi)統方(fang)面,給(gei)水(shui)(shui)在(zai)加(jia)熱(re)(re)(re)器(qi)(qi)中(zhong)(zhong)加(jia)熱(re)(re)(re)到溫(wen)度,經給(gei)水(shui)(shui)管道進入省煤器(qi)(qi),進一(yi)步加(jia)熱(re)(re)(re)以后(hou)送(song)入鍋筒(tong),與(yu)鍋水(shui)(shui)混合后(hou)沿(yan)下降管下行至水(shui)(shui)冷(leng)壁(bi)集箱。水(shui)(shui)在(zai)水(shui)(shui)冷(leng)壁(bi)管內吸(xi)收(shou)爐膛輻射熱(re)(re)(re)形成(cheng)(cheng)汽(qi)水(shui)(shui)混合物經上(shang)升管到達(da)鍋筒(tong)中(zhong)(zhong),由汽(qi)水(shui)(shui)分(fen)離裝置(zhi)使水(shui)(shui)、汽(qi)分(fen)離。 分(fen)離出來的(de)(de)(de)飽和(he)蒸汽(qi)由鍋筒(tong)上(shang)部(bu)流往(wang)蒸汽(qi)機(ji)(ji)過(guo)熱(re)(re)(re)器(qi)(qi),繼續吸(xi)熱(re)(re)(re)成(cheng)(cheng)為450℃的(de)(de)(de)過(guo)熱(re)(re)(re)蒸汽(qi),然后(hou)送(song)往(wang)汽(qi)輪(lun)機(ji)(ji)。在(zai)燃燒(shao)和(he)煙風(feng)系(xi)統方(fang)面,送(song)風(feng)機(ji)(ji)將空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)送(song)入空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)預(yu)熱(re)(re)(re)器(qi)(qi)加(jia)熱(re)(re)(re)到溫(wen)度。在(zai)磨(mo)煤機(ji)(ji)中(zhong)(zhong)被(bei)磨(mo)成(cheng)(cheng)細度的(de)(de)(de)煤粉(fen),由來自空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)預(yu)熱(re)(re)(re)器(qi)(qi)的(de)(de)(de)一(yi)部(bu)分(fen)熱(re)(re)(re)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)攜(xie)帶經燃燒(shao)器(qi)(qi)噴入爐膛。燃燒(shao)器(qi)(qi)噴出的(de)(de)(de)煤粉(fen)與(yu)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)混合物在(zai)爐膛中(zhong)(zhong)與(yu)其(qi)余的(de)(de)(de)熱(re)(re)(re)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)混合燃燒(shao),放(fang)出大量熱(re)(re)(re)量。燃燒(shao)后(hou)的(de)(de)(de)熱(re)(re)(re)煙氣(qi)(qi)(qi)順序(xu)流經爐膛、凝(ning)渣管束、過(guo)熱(re)(re)(re)器(qi)(qi)、省煤器(qi)(qi)和(he)空(kong)(kong)(kong)(kong)氣(qi)(qi)(qi)預(yu)熱(re)(re)(re)器(qi)(qi)后(hou),再經過(guo)除塵裝置(zhi),除去其(qi)中(zhong)(zhong)的(de)(de)(de)飛灰,很后(hou)由引(yin)風(feng)機(ji)(ji)送(song)往(wang)煙囪排向大氣(qi)(qi)(qi)。
