一、空氣分離設備屬于什么設備
空(kong)分(fen)(fen)設(she)備(bei)(bei)是以空(kong)氣(qi)(qi)為(wei)原(yuan)料,通過(guo)壓縮循環深度冷(leng)凍的方(fang)法把空(kong)氣(qi)(qi)變成液(ye)態,再經過(guo)精(jing)餾而從液(ye)態空(kong)氣(qi)(qi)中逐步分(fen)(fen)離(li)(li)生產出氧氣(qi)(qi)、氮氣(qi)(qi)及氬氣(qi)(qi)等惰性(xing)氣(qi)(qi)體(ti)的設(she)備(bei)(bei),它屬于氣(qi)(qi)體(ti)分(fen)(fen)離(li)(li)設(she)備(bei)(bei)。
氣(qi)(qi)體(ti)(ti)分(fen)離(li)設(she)備(bei)(bei)(bei)(bei)是指(zhi)將氣(qi)(qi)體(ti)(ti)液化(hua)、精餾、最終分(fen)離(li)成(cheng)為氧、氮和(he)其他有(you)用氣(qi)(qi)體(ti)(ti)的設(she)備(bei)(bei)(bei)(bei),常見(jian)的氣(qi)(qi)體(ti)(ti)分(fen)離(li)設(she)備(bei)(bei)(bei)(bei)除了空氣(qi)(qi)分(fen)離(li)設(she)備(bei)(bei)(bei)(bei)外,還有(you)天然氣(qi)(qi)分(fen)離(li)設(she)備(bei)(bei)(bei)(bei)、合(he)成(cheng)氨弛(chi)放氣(qi)(qi)分(fen)離(li)設(she)備(bei)(bei)(bei)(bei),以(yi)及(ji)焦爐氣(qi)(qi)、水煤氣(qi)(qi)分(fen)離(li)設(she)備(bei)(bei)(bei)(bei)和(he)稀有(you)氣(qi)(qi)體(ti)(ti)提取(qu)設(she)備(bei)(bei)(bei)(bei)。
二、空分設備有哪些分類
空分設備的形式、種(zhong)類眾多,按照(zhao)不(bu)同(tong)的分類方法,可分為(wei)不(bu)同(tong)類型(xing):
1、按產品產量(指氧氣產量)大小分
有大型(xing)空(kong)(kong)分設備(≥10000m3/h)、中型(xing)空(kong)(kong)分設備(≥ l000m3/h)和小型(xing)空(kong)(kong)分設備(< l000m3/h)三種類型(xing)。
2、按流程所需要的壓力分
可分為高(gao)壓(ya)(ya)(ya)(ya)(ya)流程(cheng)(cheng)(cheng)(cheng):正常(chang)操(cao)作(zuo)壓(ya)(ya)(ya)(ya)(ya)力(li)>5MPa的工(gong)(gong)藝流程(cheng)(cheng)(cheng)(cheng)。中壓(ya)(ya)(ya)(ya)(ya)流程(cheng)(cheng)(cheng)(cheng):正常(chang)操(cao)作(zuo)壓(ya)(ya)(ya)(ya)(ya)力(li)>1MPa至≤5MPa的工(gong)(gong)藝流程(cheng)(cheng)(cheng)(cheng)。低(di)(di)壓(ya)(ya)(ya)(ya)(ya)流程(cheng)(cheng)(cheng)(cheng):正常(chang)操(cao)作(zuo)壓(ya)(ya)(ya)(ya)(ya)力(li)≤1MPa的工(gong)(gong)藝流程(cheng)(cheng)(cheng)(cheng)。高(gao)低(di)(di)壓(ya)(ya)(ya)(ya)(ya)流程(cheng)(cheng)(cheng)(cheng):低(di)(di)壓(ya)(ya)(ya)(ya)(ya)流程(cheng)(cheng)(cheng)(cheng)與高(gao)壓(ya)(ya)(ya)(ya)(ya)流程(cheng)(cheng)(cheng)(cheng)相結合的工(gong)(gong)藝流程(cheng)(cheng)(cheng)(cheng)。
3、按用途分
可分為氣(qi)體(ti)設(she)(she)(she)(she)備(氣(qi)氧、氣(qi)氮、氣(qi)氬設(she)(she)(she)(she)備)和液(ye)體(ti)設(she)(she)(she)(she)備(液(ye)氧、液(ye)氮設(she)(she)(she)(she)備)兩種。
4、按配套換熱器類型分
有全板式空分設備(分餾塔內所有(you)的換(huan)(huan)(huan)熱設(she)備(bei)都采(cai)用板翅式(shi)(shi)換(huan)(huan)(huan)熱器(qi))、管(guan)(guan)板式(shi)(shi)空(kong)分設(she)備(bei)(除蓄冷器(qi)外,其余(yu)的換(huan)(huan)(huan)熱器(qi)系采(cai)用板翅式(shi)(shi)結構(gou))、管(guan)(guan)式(shi)(shi)空(kong)分設(she)備(bei)(所有(you)換(huan)(huan)(huan)熱器(qi)都采(cai)用盤管(guan)(guan)、列管(guan)(guan)、蓄熱填料(liao)式(shi)(shi)結構(gou))。
