Ob lub rooj sib tham xyoo no tau muaj nyob rau hauv Great Hall of the People hauv Beijing thaum Lub Peb Hlis 5, 2021, thiab carbon peaking thiab carbon neutrality tau sau rau hauv daim ntawv qhia ua haujlwm ntawm tsoomfwv thawj zaug! Premier Li Keqiang tau taw qhia hauv Daim Ntawv Qhia Ua Haujlwm ntawm Tsoomfwv ntawm Pawg Neeg Saib Xyuas Xeev xyoo 2021 tias tsoomfwv yuav tsum ua haujlwm zoo kom ua tiav qhov siab tshaj plaws carbon thiab carbon neutrality, tsim ib txoj kev npaj ua haujlwm kom ua tiav qhov siab tshaj plaws carbon emissions los ntawm xyoo 2030, thiab ua kom zoo dua cov qauv kev lag luam thiab cov qauv zog. Ob lub tswv yim no tau kub hnyiab, yog li maj nrawm thiab nrhiav seb lub ntsiab lus ntawm carbon peaking thiab carbon neutrality yog dab tsi!
Cov pa roj carbon tsis muaj zog txhais tau tias cov tuam txhab, cov pab pawg lossis cov tib neeg ntsuas tag nrho cov pa roj av uas tsim tawm ncaj qha lossis tsis ncaj qha hauv ib lub sijhawm, thiab them lawv cov pa roj carbon dioxide los ntawm kev cog ntoo, txuag hluav taws xob thiab txo cov pa roj carbon dioxide, kom ua tiav "xoom emission" ntawm carbon dioxide. Lub "carbon peak" txhais tau tias Tuam Tshoj cog lus tias yuav siv zog los tiv thaiv kev loj hlob ntawm cov pa roj carbon dioxide los ntawm xyoo 2030, thiab maj mam txo lawv tom qab mus txog qhov siab tshaj plaws.
Cov lus "Carbon" hauv cov tswv yim ntawm carbon neutrality thiab carbon peaking yeej yog hais txog carbon dioxide, tshwj xeeb tshaj yog cov carbon dioxide tsim los ntawm tib neeg kev tsim khoom thiab kev ua neej nyob. Peb txhua tus paub tias nyob rau xyoo tas los no, qhov cuam tshuam ntawm lub ntiaj teb lub ntiaj teb tau ua rau muaj ntau yam teeb meem kev puas tsuaj rau ib puag ncig, thiab ntxiv rau qhov nce ntawm cov pa roj carbon dioxide, cov ncej kuj tau pib ua kom cov dej khov yaj sai dua. Raws li cov ntaub ntawv txheeb cais, cov dej khov hauv Greenland tuaj yeem yaj 2 billion tons ib hnub. Ntxiv mus, muaj ntau cov roj methane nyob hauv qab permafrost, thiab thaum permafrost yaj, nws yuav ua rau cov nyhuv ntawm lub ntiaj teb ...
Tuam Tshoj tau ua tiav zoo kawg nkaus, nrog rau Tuam Tshoj cov pa roj carbon dioxide poob qis 48.1% hauv xyoo 2019 piv rau xyoo 2005, ua ntej lub hom phiaj xyoo 2015 ntawm kev txo qis 40% txog 45%; txij li lub Rooj Sib Tham Thib 18, Tuam Tshoj feem ntawm lub zog huv hauv kev siv zog tag nrho tau txog 23.4%, nrog rau lub peev xwm teeb tsa ntawm hydropower, cua zog thiab hnub ci zog txhua qhov qeb duas siab hauv ntiaj teb.
Txawm hais tias cov pa roj carbon dioxide ua rau muaj kev hloov pauv thoob ntiaj teb, tsis tas yuav tham txog "carbon", nws yog cov pa roj carbon dioxide ntau dhau uas ua rau muaj ntau yam teeb meem tsis zoo, thiab cov pa roj carbon dioxide tsis yog qhov phem kiag li. Peb txhua tus paub tias cov nroj tsuag xav tau cov pa roj carbon dioxide rau photosynthesis, thiab hauv kev ua liaj ua teb, qee cov pa roj carbon dioxide tuaj yeem ntxiv rau kom nce cov qoob loo; nws yog siv los ua qhov chaw ntawm cov pa oxygen hauv kev dhia dej thiab kev ya dav hlau; nws feem ntau siv ua lub tshuaj tua hluav taws; thiab nws yog ib qho khoom siv tseem ceeb hauv kev lag luam. Nws yog siv los tsim ntau cov tshauv soda, baking soda, urea, thiab lwm yam, thiab hauv kev lag luam sib zog los tsim cov dej haus carbonated, npias, dej qab zib, thiab lwm yam; nws kuj tuaj yeem ua cov dej khov qhuav, zoo li nag los dag, thiab lwm yam. Nws tuaj yeem hais tias nws yog ib qho roj tseem ceeb hauv tib neeg cov khoom txhua hnub, thiab tus nqi siv yog siab heev. Txawm li cas los xij, hauv kev tsim khoom, nws yog qhov tsim nyog yuav tsum tau them sai sai rau qhov tseeb tias qhov concentration ntawm cov pa roj carbon dioxide siab dhau, uas yuav ua rau cov concentration ntawm carbonic acid hauv tib neeg cov ntshav, txhim kho acidity thiab tsim acidosis. Thaum cov pa roj carbon dioxide hauv huab cua muaj li ntawm 1%, tib neeg yuav xav tias tsis muaj zog, kiv taub hau thiab mob plawv; thaum muaj li ntawm 4% -5%, lawv yuav kiv taub hau; thaum muaj li ntawm 6% lossis ntau dua, tib neeg yuav tsis meej pem thiab lawv txoj kev ua pa yuav tsum maj mam nres, uas ua rau tuag taus. Yog li ntawd, hauv qee lub chaw tsim tshuaj lom neeg, chaw ua cawv txiv hmab, chaw cog qoob loo, chaw ua liaj ua teb thiab lwm qhov chaw, nws yog qhov zoo dua los teeb tsa cov pa roj carbon dioxide sensors los ntes cov pa roj carbon dioxide kom tsis txhob muaj xwm txheej txaus ntshai.
HENGKO CO2 sensormuaj kev rhiab heev, kev ua haujlwm ruaj khov thiab kev ntsuas raug: av (40ppm + 3%FS) (25 ° C); lub sijhawm teb sai. Muaj lub cim LED nyob rau sab xub ntiag los qhia qhov xwm txheej ceeb toom tam sim no. Siv lub pob zeroing thiab lub pob calibration los kho lub detector, uas yooj yim rau cov neeg siv kho lub detector ncaj qha rau ntawm qhov chaw, thiab tuaj yeem muab cov zis tam sim no 4-20mA.
HENGKO lub tsev tiv thaiv kev tawg ntawm lub sensor rojmuaj ntau hom qauv uas tiv taus kub, tiv taus xeb, tiv taus plua plav, tiv taus tawg, thiab muaj peev xwm cais hluav taws kub tau zoo, thiab peb cov khoom muaj qhov nkag tau zoo thiab pom tseeb rau kev kuaj pom roj hauv qhov chaw ib puag ncig txij li -70 ° C txog 600 ° C, tiv taus siab 150 Pa, thiab qhov loj ntawm qhov pore txij li 0.2 μm - 90 μm xaiv tau. Lwm cov hlau nickel-based alloys tuaj yeem hloov kho yog tias koj daim ntawv thov xav tau kev tiv taus xeb, kub, puas thiab kev co ntau dua.
