1. Kuparadzaniswa kwekugadzirisa kwekugadzirisa kurongedza kwakakwirira, uye chiyero chekuchera chekugadzirisa shongwe yakakwirira.Iyo okisijeni uye nitrogen yekubvisa mazinga emidziyo yekuparadzanisa mhepo yakakamurwa kuva marudzi maviri: chiyero chekubvisa cheseti yakakwana yemidziyo uye chiyero chekubvisa cheshongwe yekugadziridza.Pamusana pehuwandu hwekuchera kweseti yakakwana yezvigadzirwa uye kukwanisa kwemhepo yekuparadzanisa michina.Kubuda kwezvigadzirwa zvemvura kunoenderana nezvimwe zvinhu.Zvakaoma kuyera kuparadzaniswa kwepamusoro kwekugadzirisa kwekugadzirisa kurongedza.Muyero wekubvisa wekoramu yekugadzirisa uye chiyero chekubvisa che argon chinogona kumiririra zvirinani dhizaini yedhizaini yekuparadzanisa mhepo.sub-equipment.Iyo oxygen yekubvisa mwero weshongwe yayo yekugadziridza yasvika kupfuura 99%;iyo argon extraction rate yasvika 79%.
Kukosha kwekushanda kwehuwandu hweokisijeni mumugero we nitrogen mushongwe yepamusoro ndiyo chiratidzo chikuru chekuwedzera kwekugadzirisa uye kubvisa.Chiyero chaicho chinoratidza kuti iyo okisijeni yemukati mune tsvina yenitrogen inogona kuva isingasviki 0.1%, uye kunyange kusvika 150-200x10-4%.
Iyo yepamusoro mbiru yekurongedzerwa yakarongedzerwa uye isina kuchena argon column ine yakakwirira yekuparadzanisa kugona, inova mhedzisiro yekudzikiswa kwavo kwakanyanya kushanda.Iyo yakaderera kushandiswa kwekushanda, zvakanyanya kunaka kuparadzaniswa kweokisijeni, nitrogen uye argon, uye kupatsanurwa kweokisijeni uye argon..Kazhinji, chiyero chekubvisa okisijeni chinogona kuwedzerwa ne1% kusvika 3%;chiyero chekuchera argon chinogona kuwedzerwa ne5% kusvika ku10%.
Mutengo wekubvisa weshongwe inogadzirisa zvakare unoenderana zvakanyanya nehuwandu hwemhepo yakawedzerwa inopinda mushongwe yepamusoro, iyo ine simba guru padanho rekutorwa kweArgon.Naizvozvo, iyo isentropic kunyatsoshanda kweiyo turboexpander uye iyo booster ratio yeiyo booster inoramba ichiwedzera., ndiyo kiyi yekuwedzera chiyero chekuchera cheiyo distillation column.
2. Kushaikwa kwekurongedza kwakarongeka kwakakura, huwandu hwekugadzira hwakakura, uye dhayamita yeshongwe inodzikiswa kuti ifambise kufambisa.
Iyo porosity yekurongedza yakarongeka inogona kusvika kupfuura 95%.Mune sieve plate column, nzvimbo ye orifice plate inosvika makumi masere muzana echikamu chemuchinjiko wekoramu, uye chiyero chekuvhura chingangoita 8 kusvika 12%, iyo ishoma kwazvo kupfuura kudonha kwemhepo kwekurongedza. layer.Pamutoro wakafanana, muyero wedhiyabhorosi yekoramu yakarongedzwa Iyo sieve tray tower idiki;kazhinji, nzvimbo yayo yepakati-chikamu inongova ~ 70% ye sieve tray tower, iyo inobatsira kutakura kune yakakura-yakakura mhepo yekuparadzanisa miti.
3. Iyo yakarongeka yekurongedza ine zvishoma mvura inobata simba, yakakura yekushandisa fluid-to-gas ratio uye elasticity, uye nekukurumidza kuchinja mamiriro ekushanda.
Kuremerwa kweseve tray shongwe kunogumira neseve kuvuza uye nekumhanya kwemvura mafashama, nepo shongwe dzakazara dzinongogumira nekumhanya kwemafashama emvura, saka mitoro yavo yekushandisa inogona kusiyanisa mukati mehupamhi hwakasiyana, uye dhizaini inorema shongwe dzakazara dzinogona kusvika makumi mana. % ～120%, iyo okisijeni inobuda yeshongwe yepamusoro yekurongedza kwakarongeka kwe12000m3 / h kuparadzaniswa kwemhepo yeShanghai Iron uye Steel No. huwandu huri 75%% ~117%.
Nekuda kweiyo diki yemvura inogadzika shongwe yakarongedzwa, inowanzongoita 1% kusvika 6% yeshongwe vhoriyamu, nepo mvura inosimudza sieve tray tower iri 8% kusvika N% yeshongwe vhoriyamu.Nguva yekugara ipfupi uye kuderera kwekushanda kwekushanda kuduku, iyo inobatsirawo kushanda kwemamiriro ezvinhu akasiyana-siyana ekushanda, asi inofanira kusimbiswa mukushanda kwechokwadi kwemamiriro ekushanda akasiyana mune ramangwana.
4. Nguva yekutanga yechigadzirwa inopfupiswa zvikuru
Iyo yekutanga-up process yemhepo yekuparadzanisa chirimwa hapana chigadzirwa chinobuda kushanda, saka kupfupisa nguva yekutanga-yekutanga ndiyo imwe yenzira dzekuti mhepo yekuparadzanisa chirimwa kuchengetedza simba uye kuderedza kurasikirwa.Mushure mekushandisa iyo iripo yakarongedzerwa kurongedza, huwandu hwemvura hwainobata panguva yekugadziriswa kwacho hunodzikiswa zvakanyanya, izvo zvinopfupisa zvakanyanya nguva yekutanga-yemhepo yekuparadzanisa chirimwa.
