cryogenic tank

Matangi ekuchengetedza anongobvumidzwa kusimudzwa, kutakurwa kana kutamiswa pasina mutoro, uye kutakurwa kana kutamiswa nemvura (gasi) inorambidzwa zvachose. Iyo tangi yekuchengetera chigadzirwa inobvumidzwa chete kuve nemhando imwe yepakati.

Okisijeni isimbi yakasimba inotsigira kupisa, iyo inogona kuwedzera kupisa kana kutokonzera kuputika munzvimbo ine oxygen yakawanda. Hapana zvinopisa zvinotenderwa zvakatenderedza 4 midziyo ine liquid oxygen (oxygen). Zvose zvikamu zvinosangana neokisijeni yemvura (okisijeni) inofanira kurapwa pasina mafuta uye yakasimbisa kuwirirana kwayo neokisijeni.

Mhando dzakasiyana dzevaporisers. Zvinoenderana negwara rekuyerera kwemhepo, kune marudzi maviri: kumusoro-kukweva uye kudzika-kuyamwa. Nekuvaka, kune imwe uye yakawanda injector carburettors.

Kana iyo carburettor iri kushanda, apo piston inofamba pasi uye vheji yekupinda ichizaruka, mhepo kubva mumhepo sefa inopinda nepainopinda uye inoyerera ichipinda mucarburettor kuburikidza nemhepo damper.

Iyo vapouriser inowanzozivikanwa se "carburetor". Iyo inonyanya kukosha chidimbu chemidziyo mumafuta ekupa system yeinjini yepeturu. Inoshandiswa kupfutidza peturu uye kugadzira musanganiswa unopisa unopisa nemhepo. Kazhinji inoumbwa nezvinoyangarara, makamuri anoyangarara, mavharuvhu etsono, huro, majekiseni emafuta uye maburi ekuyeresa.

Liquefied natural gas (LNG) isvikiro rinopisa uye rinoputika. Nzvimbo yekushandiswa inofanira kutungamirirwa maererano nemitemo yegesi, nearamu yegesi uye midziyo yekucheka, magetsi anoshandiswa anofanira kunge ari emagetsi anoputika, uye maturusi anoputika anofanira kushandiswa pakushanda nekugadzirisa.

Tangi yekuchengetera ine cryogenic kana yakaderera-tembiricha yepakati, uye kusangana zvakananga nevashandi kunogona kukonzera kupisa kwechando kwakafanana nekupisa. Mushandi anofanira kuchengetedza maziso neganda zviri nyore kubata negasi remvura kana chando, sekupfeka magirazi ekudzivirira kana nhovo dzechiso, uye magurovhosi eantifreeze nezvimwe.

Yedu cryogenic liquid tangi yekuchengetedza okisijeni, inosanganisira silinda yekunze yakagadzirwa neS30408 ​​simbi isina tsvina uye cylinder yemukati yakaiswa muhumburumbira hwekunze, ine bhachi pakati pehumburumbira yekunze uye cylinder yemukati. Yakati silinda yekunze yakakomberedzwawo nemitsara yakawanda yekusimbisa hoops, akati hoops yekusimbisa inopihwa mhete dzerabha kunze.

Ese ari maviri akamira uye akachinjika LNG matangi ane chiyero chemvura mita munzvimbo ine mukurumbira, ikozvino inonyanya kusiyanisa nhanho yekumanikidza mita, iyo inoshanda pamusimboti wekuti kana mwero wemvura mumudziyo uchichinja, iyo static pressure inogadzirwa neiyo mvura column inochinjawo saizvozvo.

Iyo vaporiser inogadzirwa nekambani yedu ine zvinotevera zvakanakira:
1 Ichi chigadzirwa chigadzirwa chinoshanda nesimba, chinogona kuchengetedza simba rakawanda zvichienzaniswa nemhepo inopisa vaporizer uye yekugeza mvura mhando yemagetsi inopisa vaporizer. Chigadzirwa chacho chiri muzinga repamusoro mune imwechete indasitiri.

Panguva yekushanda, kuchengetedzwa kwakarurama uye mitemo yekushanda inofanira kunyatsocherechedzwa. Isu tinokurudzira vatengi vedu kuti vasimbise kuchengetedza uye kuchengetedza mashandiro emitemo kune vashandi vavo nevashandisi.

Zvakananga zvinhu ndezvizvi:
(1) Iyo yekutsigira sisitimu yekamuri yemukati inogadzirwa nesimbi isina tsvina, ine inonzwisisika uye yakavimbika rutsigiro, iyo inogona kuwana yakaderera kupisa kurasikirwa uye simba rakawanda.

Welded insulated gasi cylinders (inozonzi gasi cylinders) ine kaviri-layer chimiro, ine insulating layer pakati peinner liner uye kunze goko. Iyo insulating layer inoshongedzerwa neakawanda akaturikidzana e insulating zvinhu uye inochengetedza yakakwira vacuum, uye inoshandiswa kutakura uye kuchengetedza yakadzika inotonhora zvinwiwa senge mvura nitrogen uye liquid oxygen.

Izvo zvakajairika zvemukati weokisijeni mumhepo inenge 21%. Zvingave zvichikonzerwa nekutsva kana kupinda kwemamwe magasi, kuderedzwa kweokisijeni iri mumhepo kunogona kuve nengozi.

Iyo tangi yekuchengetedza inoumbwa nekabhoni simbi kana Stainless simbi shell uye yekumanikidza mudziyo yakaiswa mairi. Iyo interlayer ndeye-multi-layer winding insulation uye inochengetedza yakakwira vacuum state. Nzvimbo yacho inoshandiswa pasi pekumanikidzwa kwekugadzira maererano nemamiriro chaiwo.

Yakananga maitiro emvura okisijeni yekuchengetedza tank

LNG matangi ekuchengetedza anowanzo kupatsanurwa kuita akatwasuka uye akachinjika mhando seLNG yekuchengetedza michina. Zvakanakira matangi akatwasuka zvinonyanya kuve mudiki tsoka, uye zvinodikanwa zvetangi cofferdams uye nzvimbo yekuchengetedza zvidiki pane izvo zvakachinjika LNG ekuchengetedza matangi pakuvaka dzakamira LNG yekuchengetedza tangi gasification zviteshi, saka ivo vanosarudzwa nevashandisi vebhizinesi.

Patinogadzira LNG matangi ekuchengetedza cryogenic, kuitira kuti tive nechokwadi chokuti mhepo inopisa mukati me tangi yakajairika, kunze kwekutsvaira pakati pemukati nekunze kwemukati, tinotorawo pamusoro petangi kuti igare ichitonhora uye pasi petangi kuti iparadze kutonhora.

Iyo yemukati tangi madziro ndicho chinhu chikuru cheiyo cryogenic yekuchengetedza tangi uye inogadzirwa neakadzika tembiricha inodzivirira simbi mahwendefa ane yakanaka mechanical zvivakwa zvakabatanidzwa pamwechete.

Sezvo tangi yekuchengetera kabhoni dhiabhorosi ndiko kuchengetwa kwemvura yakadzika-tembiricha, kana tsaona yaitika, mvura yefiriji inoputika yakawanda, huwandu hwefiriji yegasi yemamiriro ekutanga kanosvika mazana matatu, mumhepo inozogadzira otomatiki detonation gasi guru.

Mukugadzira yakadzika tembiricha yemvura yekuchengetera matangi, kuitira kuti ive nechokwadi chekudzivirira, yekambani yedu yekudzivirira zvinhu kusarudzwa pasi penzvimbo inopisa yepearl jecha rinozadza sandwich uye vacuum.

Nekuwedzeredza kwasara kushushikana kunokonzerwa newelding, iyo welding inosara inoshushikana inofanirwa kubviswa mushure mewelding. Industrial liquid nitrogen patembiricha yakaderera kubva kunitrogen yakatsikirirwa kuita mvura isina ruvara, ipapo tembiricha yemvura nitrogen yakadzikira kwazvo,

Isu tiri mukugadzira yakaderera tembiricha kumanikidza midziyo, kune yakaderera tembiricha kumanikidza midziyo kutanga pane zvese kusarudza zvinhu zvakakodzera, zvinhu izvi zvinofanirwa kuve nekusimba kwakanaka pakushandisa tembiricha.

Dhizaini tembiricha ye -20 ℃ pazasi pemudziyo wekumanikidza: liquefied ethylene, liquefied natural gasi, liquid nitrogen uye liquid hydrogen chengetedzo uye kutakura kwemidziyo midziyo yakaderera tembiricha yekumanikidza.

Iyo yakaderera tembiricha yemvura nitrogen yekuchengetera tangi yakatevedzana ndeye kaviri-layer vacuum poda adiabatic yekuchengetedza tangi yekuchengetera mvura okisijeni, liquid nitrogen, liquid argon, carbon dioxide uye liquefied gasi.

Bhodhoro reDewar imudziyo diki wekumanikidza unoshandiswa mhepo kuti upe mweya wakanaka wepanyama panguva yekushandiswa. Dzivirira kubuda kwegasi mumhepo yebasa. Bata zvakapfava, dzivirira kuputsika kwemasilinda uye zvishongedzo, uye shongedza midziyo yekurapa yekukurumidzira yekudonha.

Iyo yemvura argon cryogenic yekuchengetedza tangi inogadzirwa nesimbi isina tsvina yemukati lining uye Q235B kana Q345R yekunze lining, uye iyo yekumusoro anti-corrosion coating inoitwa nejecha, kubvisa ngura, kufuridza, kupfapfaidza uye mamwe maitiro, nepo maviri-chikamu chinokurumidza kurapa chivharo chemvura chinoshandiswa.
