制冷加熱體機-90℃ ~ 250℃實驗室使用
反應(ying)釜是化工(gong)、制藥(yao)、發酵等生(sheng)產(chan)常用的設備,反應(ying)釜高低溫循環(huan)一體機運行的平(ping)穩直(zhi)(zhi)接(jie)關(guan)系(xi)到生(sheng)產(chan)的質量指(zhi)標和(he)(he)效(xiao)益,其中(zhong)反應(ying)釜溫度(du)其控制效(xiao)果的好壞與產(chan)品質量和(he)(he)產(chan)量有直(zhi)(zhi)接(jie)重要的關(guan)系(xi)。
在整個設備中(zhong),反(fan)(fan)應釜高低(di)溫(wen)(wen)循環一體(ti)機(ji)是比較嚴格的,也是比較復雜的,用普通(tong)常規控(kong)制方法難以(yi)實(shi)現有效的控(kong)制。在反(fan)(fan)應釜中(zhong),通(tong)過(guo)對釜內的夾(jia)套通(tong)以(yi)加熱水(shui),使釜溫(wen)(wen)升高,同(tong)時當(dang)加熱到預定反(fan)(fan)應溫(wen)(wen)度后(hou)就停止(zhi)加熱,反(fan)(fan)應過(guo)程中(zhong)在夾(jia)套中(zhong)通(tong)以(yi)冷卻水(shui),將反(fan)(fan)應產生(sheng)的多余熱量(liang)移(yi)走,控(kong)制溫(wen)(wen)度保持恒(heng)定。
反(fan)(fan)(fan)應(ying)過程中(zhong)反(fan)(fan)(fan)應(ying)釜溫(wen)(wen)(wen)度(du)(du)(du)控(kong)制方法(fa),通常(chang)是在反(fan)(fan)(fan)應(ying)釜中(zhong)設置(zhi)溫(wen)(wen)(wen)度(du)(du)(du)傳感器以檢測(ce)反(fan)(fan)(fan)應(ying)釜溫(wen)(wen)(wen)度(du)(du)(du),當反(fan)(fan)(fan)應(ying)釜溫(wen)(wen)(wen)度(du)(du)(du)高(gao)于預(yu)定反(fan)(fan)(fan)應(ying)溫(wen)(wen)(wen)度(du)(du)(du)時(shi)(shi),在夾(jia)套中(zhong)通以冷卻水,將(jiang)反(fan)(fan)(fan)應(ying)產(chan)(chan)生的多(duo)余熱量移走,控(kong)制反(fan)(fan)(fan)應(ying)過程中(zhong)反(fan)(fan)(fan)應(ying)釜溫(wen)(wen)(wen)度(du)(du)(du)保持恒定。這種溫(wen)(wen)(wen)度(du)(du)(du)控(kong)制方法(fa)在判斷反(fan)(fan)(fan)應(ying)釜溫(wen)(wen)(wen)度(du)(du)(du)高(gao)于預(yu)定反(fan)(fan)(fan)應(ying)溫(wen)(wen)(wen)度(du)(du)(du)時(shi)(shi),才(cai)進行(xing)調整,存在大(da)的滯后性(xing),很容易(yi)導致后續(xu)生產(chan)(chan)控(kong)制參數(shu)不穩定,產(chan)(chan)品合(he)格率低(di),反(fan)(fan)(fan)應(ying)釜效率低(di)下。
為了生產(chan)出高質量的(de)(de)化(hua)學合成產(chan)品,高低溫(wen)循環一(yi)體機需在(zai)生產(chan)過(guo)(guo)程中對反應(ying)釜(fu)中的(de)(de)溫(wen)度(du)變化(hua)進(jin)行實時監控,尤其是(shi)在(zai)強(qiang)吸熱和強(qiang)放熱的(de)(de)反應(ying)過(guo)(guo)程中。而在(zai)流程工藝(yi)技(ji)術(shu)中,可(ke)靠性(xing)也是(shi)需要重視的(de)(de)。長期穩(wen)定的(de)(de)工作包括在(zai)低溫(wen)范圍內的(de)(de)穩(wen)定性(xing),只有(you)在(zai)恒定的(de)(de)工作條件下,才能保證流程工藝(yi)的(de)(de)模(mo)擬(ni)過(guo)(guo)程以及合成技(ji)術(shu)的(de)(de)可(ke)靠性(xing),從而投入實際生產(chan)。
反應(ying)釜高低溫(wen)循環一體機的(de)(de)輔助功(gong)(gong)能保(bao)證了控(kong)溫(wen)過程的(de)(de)穩(wen)定性。其(qi)自檢系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)能夠自動監(jian)測設備(bei)狀(zhuang)態并將錯誤信息顯示在(zai)液晶(jing)屏(ping)上。此外如過溫(wen)保(bao)護(hu)(hu)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)、泵(beng)超載保(bao)護(hu)(hu)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)、液位監(jian)測保(bao)護(hu)(hu)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)等,這些功(gong)(gong)能使得這一系(xi)(xi)(xi)列產品超越(yue)了以(yi)往的(de)(de)工藝過程控(kong)溫(wen)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)。其(qi)流量監(jian)控(kong)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong),在(zai)整個控(kong)溫(wen)過程中,可以(yi)有效防止過熱和(he)冰凍現(xian)象(xiang)。
反(fan)應釜(fu)高低溫循環(huan)一體(ti)機(ji)采(cai)用密閉(bi)系統(tong)設計,其內部導熱液不直接與環(huan)境(jing)空(kong)氣相互接觸(chu),即使要補償導熱液因(yin)溫度變化而(er)引(yin)起的(de)體(ti)積變化時,也使用密閉(bi)膨脹(zhang)罐。該設計能避(bi)免低溫時環(huan)境(jing)中濕氣的(de)冷(leng)凝(ning)和(he)(he)高溫下(xia)有害氣體(ti)的(de)揮發,并可以降低導熱液介質(zhi)的(de)揮發和(he)(he)氧化,從而(er)延長導熱液的(de)使用壽命。
PID程序控溫(wen)(wen)(wen)(wen)制冷加(jia)(jia)熱(re)一體機采用動態(tai)控溫(wen)(wen)(wen)(wen)模(mo)塊與反應釜壁緊密貼合,傳(chuan)熱(re)有(you)效(xiao),不需要油(you)浴、冰(bing)浴就(jiu)可(ke)以實現準(zhun)確(que)控溫(wen)(wen)(wen)(wen),多種控溫(wen)(wen)(wen)(wen)模(mo)式可(ke)以滿足不同的(de)反應需求。當反應體系由于反應放熱(re)或者(zhe)加(jia)(jia)料引起體系溫(wen)(wen)(wen)(wen)度變化(hua)時,反應器(qi)能夠主動降溫(wen)(wen)(wen)(wen)或者(zhe)升溫(wen)(wen)(wen)(wen)來(lai)補(bu)償溫(wen)(wen)(wen)(wen)度變化(hua),是(shi)反應溫(wen)(wen)(wen)(wen)度維持在設定的(de)溫(wen)(wen)(wen)(wen)度
PID程序控(kong)溫制冷加熱一(yi)體機的(de)(de)觸摸屏(ping)可以讓人員方便快捷的(de)(de)改變(bian)反應過程參數,一(yi)定(ding)程度減少人與反應的(de)(de)直接接觸。PID程序(xu)控溫制冷加熱一(yi)體(ti)機預(yu)先編制操作的程序(xu),包括加料、升降(jiang)溫等,系統自(zi)動執行,提高人(ren)員的工作效率。
