Yuav ua li cas hlau 3D luam ntawv pab lub zog kev lag luam txo nws cov pa roj carbon hneev taw?

1. Kev hloov pauv ntawm kev siv cov khoom siv: los ntawm "subtractive manufacturing" mus rau "on-xav kom loj hlob"
Casting, forging, thiab machining yog qee txoj hauv kev ua haujlwm nrog hlau, tab sis feem ntau lawv tsuas yog siv 30% ntawm cov khoom. Piv txwv li, kev ua haujlwm forging ib txwm yuav tsum tau tig steel ingots uas dav 3 meters rau hauv spindles uas yog 1.5 meters dav. Kwv yees li 70% ntawm cov hlau raug txiav mus rau hauv seem thaum lub sijhawm ua haujlwm no.Hlau 3D luam ntawvtuaj yeem siv ntau dua 90% ntawm cov khoom siv los ntawm kev sib tsoo cov khaubncaws sab nraud povtseg. Platinum Technology ua rau lub foob pob hluav taws cav thrust chambers rau cov tuam txhab lag luam aerospace. Kev siv cov khoom siv tau nce los ntawm 15% hauv cov txheej txheem ib txwm siv rau 92% tom qab 3D luam ntawv. Qhov hnyav ntawm txhua qhov tau raug txiav los ntawm 60%, uas txhais tau hais tias cov pa roj carbon emissions thaum lub sijhawm foob pob hluav taws yog qis dua.
Lub "digital mould" lub ntsiab ntawm 3D luam ntawv yog dab tsi ua rau cov khoom siv tau zoo dua. Hauv kev tsim khoom ib txwm muaj, pwm yuav tsum tau ua ua ntej, uas ua rau nws kim heev los hloov cov qauv tsim. Hauv 3D luam ntawv, cov qauv digital tsav kev tsim khoom ncaj qha, uas ua rau nws yooj yim rau kev sib koom ua ke ntawm topology optimization tsim. Cov pab pawg sib tw European siv SLM (Selective Laser Melting) thev naus laus zis los ua lub cav lub tog raj kheej lub taub hau, uas txo qhov hnyav ntawm 66%, ntim los ntawm 65%, thiab thaj chaw tshav kub dissipation los ntawm 40%. Nws tseem tam sim ntawd txhim kho roj efficiency los ntawm 12% thaum ua kom nws lub zog qub. Qhov kev ywj pheej ntawm kev tsim qauv no tso cai rau cov cuab yeej siv hluav taws xob mus dhau ntawm cov neeg kho tshuab ciam teb ntawm cov qauv ib txwm siv, tso cai rau "tsim rau kev ua haujlwm" es tsis yog "tsim rau kev tsim khoom."
2. Tsawg- carbon rebuilding ntawm lub zog tsim khoom kawg: txav los ntawm centralized mus rau kev faib khoom
Txoj kev ib txwm ua ntawm kev ua cov cuab yeej siv hluav taws xob tso siab rau cov khoom siv thoob ntiaj teb. Kev sib txuas ntawm kev xa khoom los ntawm kev tau txais cov khoom siv raw los muab lawv ua ke ntawm qhov kawg ntawm cov txheej txheem tso nyiaj ntau dua 30% ntawm tag nrho cov pa roj carbon emissions. Hlau 3D luam ntawv lub peev xwm los ua khoom hauv zos yog daws qhov teeb meem no. Piv txwv li, nrog cov khoom siv hauv nruab nrab, cov khoom yuav tsum tau xa los ntawm Tuam Tshoj mus rau ntau thaj tsam ntawm lub ntiaj teb. Nrog 3D tshuab luam ntawv, txawm li cas los xij, txhua qhov kev teeb tsa tuaj yeem ua tau sai. Bering 3D tsim lub hnub ci bracket rau tej thaj chaw deb hauv Africa uas tau luam tawm ntawm qhov chaw nrog huab cua -cov hmoov hlau tiv taus. Qhov no txhais tau hais tias nws tsis tas yuav raug xa mus hla ciam teb lossis khaws cia, thiab txiav cov pa roj carbon hneev taw ntawm ib qho system los ntawm 45%.
Cov txiaj ntsig ntawm 3D luam ntawv rau kev faib khoom yog loj dua hauv kev lag luam hluav taws xob nuclear. Txhawm rau muab tso ua ke ib txwm siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob, kaum tawm txhiab tus yeeb nkab fittings yuav tsum tau tsiv mus rau qhov chaw tsim hluav taws xob nuclear. Txawm li cas los xij, Platinum Technology's BLT-S1500 ntau- cov khoom siv laser tuaj yeem ua ib yam nrog ib qho hnyav ntawm 1.5 tonnes, uas ua rau qhov kev ncua deb ntawm hla -continental mus rau hauv thaj chaw cog. Qhov no "tsim thiab installation" txheej txheem tau txiav lub sij hawm nws yuav siv sij hawm rau nruab ib tug muab CGN nuclear fais fab chaw nres tsheb los ntawm 70%, txiav tus nqi ntawm vuam xav tau ntawm qhov chaw los ntawm 90%, thiab txiav carbon emissions thaum lub sij hawm tsim los ntawm 23,000 tonnes.
3. Kev ua haujlwm dhia ntawm cov cuab yeej siv hluav taws xob huv: los ntawm kev ua kom zoo rau cov qauv kev sib xyaw ua ke
Txoj kev loj hlob ntawm cov cuab yeej siv hluav taws xob yog txav mus rau "kev ua haujlwm siab qis zog" ua tsaug rau hlau 3D luam ntawv. Nyob rau hauv lub tshav pob ntawm lub zog cua, 3D luam ntawv tau txais ib ncig ntawm cov teeb meem uas tsoos casting txoj kev muaj nrog hniav shear network architectures. Siv cov nplaum dav hlau sib txuas (BJT) thev naus laus zis, Vestas '100-meter qib cua turbine hniav cov hauv paus hniav txuas ua rau kev tsim kho yooj yim rau kev tso ua ke. Nws tau siv 127 yam khoom los ua ib qho. Qhov no txo ​​qis qhov pib torque ntawm cov hniav los ntawm 18% thaum ua kom lawv tsis txhob nkees. Nws kuj tseem ua kom cov nqi hluav taws xob tsim tawm txhua xyoo los ntawm 3.2%.
3D luam ntawv lub peev xwm los ua ke ntau qhov chaw rau hauv ib thooj kuj tseem muaj txiaj ntsig rau kev ua hydrogen- cov khoom siv hluav taws xob. Cov txheej txheem stamping ib txwm xav tau los ua kom ntau dua 200 tus kheej ntws channel pwm rau cov phaj bipolar ntawm Toyota Mirai roj cell pawg. Txawm li cas los xij, 3D luam ntawv tuaj yeem ncaj qha ua ib qho kev sib xyaw bipolar phaj nrog serpentine ntws raws, qhov rau qhov ntsuas kub, thiab qhov rau hydrogen diffusion. Qhov no ua rau cov pawg muaj zog ceev los ntawm 25% thiab kev siv hydrogen los ntawm 15%. Qhov kev sib koom ua ke no tsis yog siv cov khoom siv tsawg xwb, tab sis nws kuj txo qis lub zog ntawm lub cev siv los khiav los ntawm kev ua kom zoo rau txoj hauv kev uas lub zog siv.
4. Carbon Capture thiab siv: Los ntawm Lub Tswv Yim rau Kev Ua Haujlwm Engineering
3D luam ntawv yog kho qhov teeb meem hauv kev ntes cov pa roj carbon monoxide uas ua rau nws tsis yooj yim rau cov txheej txheem ib txwm ua kom cov txheej txheem sab hauv nyuaj. Cov lim dej nrog kaum tawm txhiab micron- qhov loj me yog xav tau rau Direct Air Capture (DAC) system, thiab cov txheej txheem ua haujlwm tsuas yog tsawg dua 30% ntawm txoj haujlwm ua tiav. Tab sis 3D luam ntawv tuaj yeem khaws qhov pore loj yuam kev mus rau hauv ± 5 μ m. Cov pa roj carbon capture reactor uas 3D Systems ua rau AirCapture muaj peb zaug ntawm tshav kub pauv cheeb tsam vim rau topology optimisation. Qhov no txhais tau hais tias nws tuaj yeem sau tau 40% ntau dua carbon ib chav tsev ntim. Nyob rau tib lub sijhawm, qhov hnyav ntawm cov khoom siv tau nqis los ntawm 12 tonnes mus rau 3.8 tonnes. Qhov no txhais tau hais tias cov pa roj carbon emissions qis dua thaum lub sij hawm xa khoom thiab kev teeb tsa.
Nws yog qhov nthuav ntau dua tias 3D luam ntawv yog ua kom cov pa roj carbon monoxide siv ntau dua. Norwegian Carbon Clean siv lub modular carbon converter reactor ua los ntawm 3D luam ntawv los ua cov txheej txheem ntawm tig CO ₂ rau hauv methanol 85% ntau zog-npaum, uas yog 22 feem pua ​​​​cov ntsiab lus ntau dua li cov txheej txheem uas twb muaj lawm. Kev tswj xyuas meej ntawm cov qauv kev kub ntxhov hauv lub reactor los ntawm 3D luam ntawv yog dab tsi ua rau qhov kev txhawb nqa hauv kev ua tau zoo. Nws ua rau thaj chaw uas cov roj thiab cov kua nkag mus rau hauv kev sib cuag los ntawm 60% thiab cov tshuaj tiv thaiv los ntawm peb zaug.
5. Kev hloov pauv ntsuab ntawm kev lag luam ecology: txav los ntawm kev lag luam tawm mus rau ib puag ncig
Hlau 3D luam ntawv kaw - lub voj ntaws hloov pauv cov saw hluav taws xob muaj zog. Platinum Technology txoj kev ua hmoov txheej tuaj yeem nce tus nqi rov qab ntawm cov hlau tawg thaum luam ntawv mus rau 99.2%. Thaum siv nrog cov khoom siv roj argon rov qab, nws tuaj yeem txiav cov pa roj carbon emissions los ntawm 187 tonnes ib xyoos rau ib chav tsev xwb. Chuangcai Advanced Study tau siv AI algorithms los tsim regenerated titanium alloy hmoov. Cov hmoov no muaj cov khoom zoo uas muaj txog li 98% ntawm cov hmoov qub, thiab nws raug nqi 40% tsawg dua los ua. State Power Investment Corporation tau siv nws los ua lub plhaub ntawm lub zog cia roj teeb.
Txoj kev khwv nyiaj txiag ncig no yog kis mus rau lwm qhov chaw. Siemens Energy tab tom tsim ib tsob nroj hauv Saudi Arabia lub NEOM New City los ua ntsuab hydrogen. Tag nrho nws cov tshuab luam ntawv 3D yog modular, uas txhais tau tias lawv tuaj yeem muab sib cais rau hauv cov qauv thiab luam tawm rau hauv cov tshuab tshiab tom qab lawv tsis xav tau lawm. Qhov no txhais tau hais tias 95% ntawm cov peev txheej tau siv thaum lub sijhawm lub tshuab ua haujlwm tag nrho. Qhov kev kaw no ntawm "kev tsim khoom siv rov tsim dua tshiab" qhia tau tias cov khoom siv hluav taws xob hloov pauv ntawm "consumables" mus rau "cov khoom ruaj khov."
