Chidule: Unikani zomwe zimayambitsa kusinthasintha kwa kutentha kwa chitsamba cha jenereta yamafuta awiri amafuta, perekani mayankho enieni, dziwani zowopsa ndi njira zodzitetezera.
Zida mwachidule
BZ 25-1 / S Oilfield (chapakati Bohai Nyanja) ya CNOOC (China) Co., LTD.Nthambi ya Tianjin (FPSO) ili ndi makina anayi opangira mafuta amtundu wa TITAN130 opangidwa ndi SOLAR.The turbine jenereta seti zikuphatikizapo chopangira mpweya injini, deceleration zida chipangizo, jenereta, gulu ulamuliro, gulu chida, m'munsi wamba, phokoso kutchinjiriza chivundikirocho ndi dongosolo wothandiza, etc. Pamene unit ntchito mafuta osiyana, kubala mphamvu kukula ndi osiyana. Chithunzi 1)
Ukonde linanena bungwe mphamvu turbine ndi 13500kW ndi liwiro ndi 11220rpm, ndi linanena bungwe mphamvu ya jenereta kukhazikitsidwa ndi 12500 kW pansi 40 ℃ chilengedwe chilengedwe.Mphamvu ya jenereta ndi 6300 V, 50 Hz, 3 ph, mphamvu ndi 0,8 PF;chipangizocho chili ndi khushoni yonyamulira, kunyamula shaft m'mimba mwake, ndipo chochepetsera chili ndi zida za pulaneti za Gulu 3.Chilichonse chonyamulira mafuta chimatengera njira yolimbikitsira mafuta apakati.
Zida zinayi zamtundu wa TITAN130 zopangira mafuta amtundu wapawiri zimatha mphamvu pamalo onse amafuta, ndipo pali zida zinayi zobwezeretsa kutentha kwa zinyalala.Mafuta apakati amatenthedwa ndi kutentha kwakukulu kwa gasi wopangidwa ndi turbine.Kugwira ntchito mokhazikika komanso kotetezeka kwa seti zinayi za jenereta zamafuta apawiri a TITAN130 ndizofunikira kwambiri.

Chithunzi 3 Tchati choyenda chamafuta a unit
Kuti muwone chomwe chimayambitsa kutentha kwa chitsamba chonyamula, zitha kukhala kuti ma varnish amapangidwa mumafuta opaka mafuta a unit, ndipo varnish pamapeto pake imakhazikika pa chitsamba chonyamula, zomwe zimapangitsa kusinthasintha kwa kutentha ndi kukwera kwa chitsamba chonyamula.
3.1.2Zifukwa za varnish
* Mafuta opaka mamineral amapangidwa makamaka ndi ma hydrocarbon, omwe amakhala osasunthika potentha komanso kutentha pang'ono.Koma ngati pakakhala kutentha kwakukulu, ena (ngakhale chiwerengerocho chili chochepa kwambiri) mamolekyu a hydrocarbon adzakumana ndi okosijeni, mamolekyu ena a hydrocarbon adzatsatiranso machitidwe a unyolo, omwe ndi khalidwe la hydrocarbon chain reaction;
* Mafuta opaka mafuta amapanga vanishi wosungunuka m'malo otentha komanso opanikizika kwambiri.Pamene mafuta akuyenda kuchokera kumalo otentha kwambiri kupita kumalo otsika kutentha, kuchepa kwa kutentha kumabweretsa kuchepa kwa kusungunuka, ndipo tinthu ta varnish timachokera ku mafuta odzola ndikuyamba kuyika;
* Kuyika kwa varnish kumachitika.Pambuyo mapangidwe varnish particles, matope akuyamba condense ndi kupanga matope adzakhala amakonda waikamo pa otentha zitsulo pamwamba, chifukwa chitsamba kutentha nyamuka mofulumira mmbuyo mafuta kutentha nawonso pang`onopang`ono nyamuka;
* Kusinthasintha kwa kutentha komwe kumatha kuyambitsidwa ndi zinthu zina zachilengedwe kapena zovuta zagawo.
3.2 Njira zothetsera vuto la kutentha kwa chitsamba chonyamula
3.2.1 Kwezani mphamvu yamafuta opaka mafuta kuchoka pa 0.23 Mpa kufika pa 0.245 Mpa kuti muzitha kutengera kutentha kwamafuta ndikuchepetsa kutsika pang'onopang'ono kwa kutentha kwa chitsamba.
3.2.2 Bwezerani zoziziritsa kukhosi zoziziritsa kukhosi ndi kutentha kocheperako kokalamba ndi chozizira chatsopano chapakhomo, ndipo kutentha kwamafuta otsetsereka kumakhala kokhazikika kuyambira 60 ℃ mpaka 50 ℃ kwa nthawi yayitali.
3.2.3 Mfundo yogwirira ntchito yaukadaulo wa electrostatic adsorption —— kuchotsa vanishi wocheperako (onani Chithunzi 4)
Electrostatic kuyeretsedwa ndi kugwiritsa ntchito zozungulira mkulu voteji malo amodzi kumunda, kupanga mafuta kuipitsa particles kusonyeza zabwino ndi zoipa magetsi motero, zabwino ndi zoipa particles magetsi pansi zochita za zoipa ndi zabwino elekitirodi malangizo, ndale particles kufinya ndi mlandu particles otaya, potsiriza onse particles. adsorption pa osonkhanitsa, kuchotsa kwathunthu zoipitsa mu mafuta, ndi electrostatic mafuta particles otaya, thanki, chitoliro khoma ndi zigawo zikuluzikulu za matope pa zonyansa zonse, okusayidi kukokoloka adsorption kunja, yogwira kuchotsa dongosolo pamwamba zomatira matope ndi zomatira dothi. , gwirani ntchito yoyeretsa.

3.3 Zotsatira zakuchotsa varnish
Pa Disembala 14, 2019, fyuluta yamafuta amtundu wa WVD ya varnish idayikidwa ndikugwiritsidwa ntchito.Pansi pa muyeso wathunthu wosintha choziziritsa kukhosi chamafuta a gasi pa Ogasiti 20,2020, kutentha kwa turbine yonyamula (chitsamba) kudatsika kuchokera pa 108 ℃ kufika pafupifupi 90 ℃ (onani Chithunzi 6 cha kutentha kwa kuyeretsa kumbuyo (chitsamba)).Mtundu wa mafuta umakhala wabwino kwambiri (Chithunzi 7 kuyerekezera mafuta asanayeretsedwe komanso atatha kuyeretsa).Kupyolera mu kusanthula ndi deta yoyesera yakunja, chiwerengero cha chizolowezi cha varnish ya mafuta chinachepetsedwa kuchokera ku 42.4 mpaka 4.5, mlingo wa kuipitsidwa unachepetsedwa kuchokera ku NAS 9 mpaka 6, ndipo chiwerengero cha acid acid chinachepetsedwa kuchokera ku 0.17 mpaka 0.07. (Onani Table 6 Test and kusanthula zotsatira za mafuta pambuyo fyuluta fyuluta)

Phindu lachuma lomwe limapezeka
Kupyolera mu kukhazikitsa ndi kugwira ntchito kwaWVD varnish kuchotsa unit, kuthetsa bwino turbine ya gasi yomwe imayambitsa kutentha kwa kutentha, kupewa kuwonongeka kwakukulu komwe kumabwera chifukwa cha kuwonongeka kwapang'onopang'ono ndi kutayika kwa ziwalo zosindikizira zomwe zimatayika chifukwa cha zida zosinthira, kuchepetsa kutayika kwa kutayika kwa 5 miliyoni RMB pamwamba, ndi nthawi yokonza mgwirizano ndi yaitali, palibe gawo loyimilira pamalo opangira, zomwe zimapangitsa kuti pakhale zotetezeka komanso zokhazikika.
Gawoli liyenera kudzaza migolo 20 yamafuta / unit.Pambuyo posefa filimu yochotsa utoto, mafutawo amafika pamndandanda woyenerera, ndikupulumutsa mtengo wosinthira mafuta pafupifupi 400,000 RMB.
Mapeto
Chifukwa cha kutentha kwanthawi yayitali, kuthamanga kwambiri komanso kuthamanga kwamafuta amtundu waukulu, kuthamanga kwa okosijeni wamafuta kumathamanga, index ya varnish imawonjezeka, ndipo zomwe zili mu gelatin zimawonjezeka.Kuchuluka kwa zonyansa zofewa mu dongosolo lalikulu la unit kumakhudza kulondola kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kakeGuluu la varnish lomwe limayikidwa pamwamba pa chitsamba cha shaft limapangitsanso kutentha kwa shaft, ndipo kumamatira kwa varnish ndi tinthu tating'onoting'ono kumawonjezeranso kuwonongeka kwa zida.WVD varnish kuchotsa unit akhoza mosalekeza kusintha mafuta mafuta khalidwe la unit, kuonetsetsa mkombero yaitali ntchito khola mayunitsi lalikulu, kutalikitsa mkombero wa ntchito mafuta opaka mafuta, kusintha malo ogwiritsira ntchito dongosolo, kuchepetsa mtengo wogula mafuta opaka mafuta.
