Kugwiritsiridwa ntchito kwa jenereta ya nthunzi m'makampani a oleochemical kukuchulukirachulukira, ndipo kwakopa chidwi kwambiri ndi makasitomala. Malinga ndi zofunikira zosiyanasiyana zopangira, ma jenereta osiyanasiyana amatha kupangidwa. Pakalipano, kupanga ma jenereta a nthunzi m'makampani a petroleum pang'onopang'ono kwakhala njira yofunikira pakupanga zida zopangira mafakitale. Popanga, nthunzi yokhala ndi chinyezi china imafunika ngati madzi ozizira, ndipo kutentha kwambiri ndi nthunzi yothamanga kwambiri kumapangidwa kudzera mu vaporization. Momwe mungakwaniritsire kutentha kwambiri komanso zida za nthunzi zapamwamba popanda kusokoneza ndikuwonetsetsa kuti zida za nthunzi zikuyenda bwino
1. Kutentha kwa vaporization kuli pakati pa 130-150°C
Kaya jenereta yothamanga kwambiri imatha kupereka kutentha kwambiri komanso kupanikizika ndiye chinsinsi chowonetsetsa kuti zinthu zili bwino komanso kupanga kokhazikika. Majenereta a nthunzi amatha kugawidwa mumtundu umodzi wakhoma, mtundu wophatikizidwa ndi mitundu ina. Zogulitsa nthawi zambiri zimasankha mitundu yosiyanasiyana ya ma jenereta a nthunzi malinga ndi momwe amapangira. Jenereta ya nthunzi iyenera kukwaniritsa zofunikira za ndondomekoyi. Kugwiritsa ntchito ndi mtundu wa nthunzi kumatha kusankhidwa moyenerera malinga ndi zosowa za mafakitale osiyanasiyana. Ikhoza kugwiritsidwa ntchito mwachindunji pakupanga mafuta, makampani opanga mankhwala ndi mafakitale ena, koma ngati mukufuna kukhala ndi malingaliro abwino a nthunzi, simungathe kunyalanyaza kugwiritsa ntchito zipangizo.
2. Kuthamanga kuli pakati pa 1.2-2.5MPa
Mafuta akadutsa mu jenereta ya nthunzi, mafuta okhala ndi madzi a 1% -2% amatha kukhala opanda utsi komanso kutentha kwambiri komanso kupanikizika kwambiri. Pambuyo pa kutentha kwakukulu ndi kupanikizika kwakukulu, kutentha kwakukulu ndi kuthamanga kwapamwamba, nthunzi yopanda utsi ndi yopanda pake imapangidwa. Jenereta ya nthunzi ndiyofunikira kwambiri kugwiritsa ntchito jenereta ya nthunzi kuti ikwaniritse ntchito ya zida. Chifukwa chake, opanga adzagwiritsa ntchito zinthu zopangidwa ndi ma jenereta a nthunzi popanga kuti zithandizire mafakitale amafuta ndi mankhwala. Izi ndichifukwa choti mankhwalawa amatha kupanga mafuta ndi mafuta kukhala aukhondo komanso osavuta kusunga.
3. Pamene kuthamanga kuli pansi pa 2.5MPa, sipadzakhala ngozi yophulika mu chubu
Pakupanga mafuta, pali njira zambiri monga kulekanitsa, decolorization, kusefera, ndende, ndi zina zambiri, ndipo njirayi imakhala ndi zofunika kwambiri pa nthunzi. Zipangizo zamakono zokopera madzi zimatha kupangitsa kuti madzi asungunuke kuti apange nthunzi pansi pa chinyezi china. Njirazi zimafuna kugwiritsa ntchito nthunzi. Ngati kutentha kwa nthunzi sikukwaniritsa zofunikira zina, palibe chitsimikizo kuti chowotcha sichidzaphulika. Kugwiritsa ntchito ma jenereta a nthunzi popanga mafuta amafuta kumatha kukwaniritsa zofunikira pakupanga mafuta. Komabe, jenereta ya nthunzi inakumananso ndi zovuta zina panthawi yomwe imagwiritsidwa ntchito, makamaka chifukwa cha kuwonongeka kwa kayendedwe ka madzi a nthunzi ndi madzi otuluka nthunzi, zomwe zingayambitse kuyaka kosakhazikika kwa boiler, kuphulika kwa chubu ndi kulephera kwa boiler. Palinso mabizinesi ena omwe amagwiritsa ntchito ma jenereta a nthunzi kuti apange nthunzi yothamanga kwambiri, yomwe imakhala yosawoneka bwino, yowononga, komanso yosagwira ntchito bwino. Pakadali pano, ma jenereta obwezeretsanso mafuta amagwiritsidwa ntchito mochulukira m'makampani a petrochemical, ndipo magawo omwe amawagwiritsa ntchito akuchulukirachulukira m'makampani amafuta.
4. High dongosolo chitetezo factor
Pazida zotentha kwambiri komanso zowongoka kwambiri, mfundo yogwirira ntchito ya jenereta ya nthunzi ndiyo kugwiritsa ntchito kutentha kopangidwa ndi mamolekyu a nthunzi ndi madzi kuti ipangitse nthunzi yamadzi kukhala madontho amadzi kapena kutsitsa mpweya wamadzi m'madzi kapena zinthu zina. Mpweya wamadzi ukhoza kupangidwa ndi okosijeni ndi mpweya kuti upange mpweya woyaka monga hydrogen ndi carbon monoxide. Mwanjira imeneyi, imatha kugwiritsa ntchito mpweya wamadzi kuti utenge kutentha kwakukulu kuti upange madzi kuti apange nthunzi wamadzi (nthunzi wamadzi). Mtengo wa calorific wa kutentha kwambiri komanso kuthamanga kwambiri kwa nthunzi ndi 800 ° C-1200 ° C, yomwe ndi 4-5 nthawi ya distillation yachitsulo, kotero imatha kupeŵa kuopsa kwa chitetezo cha zipangizo kapena machitidwe, ndi dongosolo ali mkulu chitetezo factor! Chifukwa chake jenereta ya nthunzi ndi chida chotetezeka cha nthunzi.
