Ungalithuthukisa kanjani izinga lomoya ekilasini?

Igumbi lokufundela liyindawo eyinhloko abafundi abangafunda ngayo nsuku zonke.Izinga lomoya ekilasini lihlobene ngokuqondile nempilo engokomzimba nengqondo yabafundi kanye nempumelelo yokufunda.Imizimba yawo isesigabeni sokukhula nokukhula, futhi ukuvikeleka kwawo ezintweni ezingcolisayo kubuthakathaka kakhulu kunakwabantu abadala.Indawo yabo yokufunda ingcono nakakhulu.Kudingeka ukunakwa okukhethekile.Ekuqaleni kwezikole zamabanga aphansi nezamabanga aphezulu, "Isu Lokuvimbela Uboya" lifinyeze izinkinga zomoya ekilasini futhi lanikeza izimo ezithile zezikole zaseJalimane ukuze kusetshenziswe iminyango yezemfundo nabazali.

1. Umoya Wasekilasini Amane Oyingozi

• Ukungena kwe-PM2.5 yangaphandle kuyingozi☆☆☆☆
• Ukugxila okuphezulu kwe-CO2 kuyingozi☆☆
• Ukusabalala kwamagciwane athathelwanayo kuyingozi☆☆☆
• Izingozi zokungcoliswa kwe-formaldehyde☆☆☆☆

Izingozi zokungena zangaphandle PM2.5 Isilinganiso senkanyezi: ☆☆☆☆

Ngosuku olushubile, ngisho noma iminyango namafasitela evalwe ngokuqinile, izinhlayiya zothuli ezincane ze-PM2.5 zisangakwazi ukungena emagumbini okufundela ngeminyango namafasitela kanye nezikhala zesakhiwo.Ukuhlola okungaphelele kubonise ukuthi ukugxila kwe-PM2.5 ekilasini kungaphansi kancane kunaleyo yangaphandle cishe ngo-10% kuya ku-20%.Lokhu kungenxa yokuthi bonke abafundi benza “njengabahlanzi benyama yomuntu.”Izinyathelo zokuvimbela zabafundi ngokumelene ne-PM2.5 zicishe zilingane noziro.Ngenxa yokuthi izinhlayiya ze-PM2.5 zincane kakhulu, umzimba womuntu awunawo amandla okuzihlunga nokuzivimba.Izinhlayiya zigwinywa kalula ngamaseli e-alveolar phagocytic futhi zingena ku-bronchus.Ngakho-ke, i-PM2.5 ingabangela umonakalo omkhulu ohlelweni lokuphefumula komuntu futhi ibangele kalula i-asthma, i-bronchitis, njll.

Ukugxila okuphezulu kwe-CO2 kulimaza ukulinganisa kwenkanyezi: ☆☆

Amathiphu esayensi adumile: Ukugxiliswa kwe-CO2 kwangaphandle cishe ku-400ppm, futhi umuntu ukhipha cishe amalitha angu-15 e-CO2 ngehora lapho ehlezi anganyakazi.Ezinsukwini zobumnyama, ebusika nasehlobo, iminyango namafasitela ekilasi kuvame ukuvalwa, futhi ukugxila kwe-CO2 kwangaphakathi kuyanda.Ukugxiliswa kwe-CO2 emakilasini abafundi abangu-35 kufinyelela ku-2000 ~ 3000ppm.Ukugxila okuphezulu kwe-CO2 kubangela ukuthi abafundi bakhiqize izimpawu ezinjengokuqina kwesifuba, isiyezi, ukuphazamiseka, ukozela, nokulahlekelwa inkumbulo.Ngakho-ke, lapho uthisha ebika ukuthi izingane zakho zizofunda njalo, cishe zizothinteka yi-CO2 embi.

Ngokwemiphumela yokuhlolwa kokunaka kwabafundi e-Austria, lapho ukugxiliswa kwe-CO2 kukhuphuka kusuka ku-600-800ppm kuya ku-3000ppm, ukusebenza kahle komfundi kwehla kusuka ku-100% kuya ku-90%.I-German Environmental Protection Agency incoma ukuthi lapho ukuhlushwa kungaphansi kuka-1000ppm, isimo senhlanzeko sinengqondo, lapho ukugxila kuyi-1000-2000ppm, ukunakwa kufanele kunakwe futhi kuthathwe izinyathelo zokungenisa umoya.Uma i-CO2 ingaphezu kuka-2000ppm, isimo sokuhlanzeka komoya asamukelekile.

Amagciwane athathelwanayo asakaza ingozi Isilinganiso senkanyezi: ☆☆☆

Amakilasi aminyene futhi umswakama uphezulu, futhi amagciwane angazalanisa kalula futhi asakazeke, njengomumpintshane, upokisi, umkhuhlane, isifo sohudo, njll.;Amakhempasi ajwayele ukuqubuka kwezifo ezithathelanayo kusukela ngoMashi kuya kuMbasa kanye no-Okthoba kuya kuZibandlela minyaka yonke.Ngo-2007, i-Shanghai yenza ukuqapha komoya ezikoleni eziyi-8 zamabanga aphansi naphakathi esifundeni sase-Fengxian, futhi yathola ukuthi inani eliphelele lamagciwane omoya ekilasini lalingu-0.2/cm2 ngaphambi kwekilasi, kodwa lenyukela ku-1.8/cm2 ngemva kwekilasi lesine.Uma igumbi lokufundela lingenawo umoya ohlanzekile, futhi inqwaba yamagciwane akhiqizwa abafundi abakhwehlelayo nokuthimula azonqwabelana futhi asakazeke, umuntu oyedwa uzogula futhi abantu abaningi bangenwe yilesi sifo.

Isilinganiso senkanyezi yengozi yokungcoliswa kwe-formaldehyde: ☆☆☆☆

Uma kuyikilasi elisanda kwakhiwa noma elilungiswe kabusha, izinto zokuhlobisa izakhiwo namadeski amasha nezihlalo kuzoshisa amagesi ayingozi, okuhlanganisa i-formaldehyde ne-benzene.Ukungcoliswa kokuhlobisa kuyingozi kakhulu empilweni yabafundi, futhi kulula ukubangela izifo zegazi ezinganeni, njenge-leukemia;ngesikhathi esifanayo, kwandisa ukutholakala kwe-asthma;futhi kuthinta ukukhula kwengqondo kwabafundi.NgoSepthemba 2013, Uphiko Lokuqondisa Lwezemvelo Lase-Wenzhou lahlola ngokungahleliwe amagumbi okufundela angama-88 ezikhungweni zemfundo yezingane ezisakhula eziyi-17 e-Wenzhou, ezingama-43 zazo zeqa izinga le-formaldehyde kanye nengqikithi yokuguquguquka kwemvelo, okusho ukuthi, ama-51% amakilasi anezinga lomoya elingafanelekile.

2. Okuhlangenwe nakho kwamaJalimane ekuhlanzekeni komoya ekilasini

Esikhathini esidlule, kwakuvame ukuba nezindaba zokuthi abazali bathumele imishini yokuhlanza umoya emakilasini esikole.Ukunyakaza okunjalo kunganciphisa kancane umonakalo womoya othile ongcolile kubafundi;nokho-ke, ukuxazulula izingozi ezine ezinkulu ezishiwo ngenhla, lokhu kuwukwehla nje kwebhakede, futhi kukude nokwanele.Ukuxazulula izingozi ezine zomoya wekilasi, ku-PM2.5, kubonakala sengathi iminyango namafasitela kufanele avalwe. ngokuqinile, futhi kwezinye izingozi ezintathu, iminyango namafasitela kufanele avulwe ukuze kwandiswe umoya.Ukuxazulula kanjani lokhu kuphikisana?Okuhlangenwe nakho kwezikole zaseJalimane ukuthi umphumela wokungenisa umoya wefasitela uthintwa isiqondiso somoya kanye nesivinini, futhi umphumela awukwazi ukuqinisekiswa, futhi umoya wefasitela ebusika nasehlobo nawo uvinjelwe;ngakho-ke, ukuze kuthuthukiswe izinga lomoya wekilasi, kuyadingeka ukulawula ngenkuthalo nangokunengqondo ukunikezwa nokukhipha umoya, ukuze kunikezwe umoya owanele.Inani lomoya ohlanzekile, khipha umoya wasendlini oshubile.Kunezinhlobo ezimbili ikakhulukazi zemishini yokufaka umoya eyimishini efakwe ekilasini:

Imishini yokufaka umoya emaphakathi.

Ilungele izikole ezisanda kwakhiwa, futhi umthamo wokungenisa umoya ungahlangabezana nomoya opholile ongu-17~20 m 3;/h kumfundi ngamunye.Insizwa enkulu ophahleni lwesithombe sekhava yimishini yokufaka umoya emaphakathi.Amapayipi ayindilinga amhlophe phezulu kwesithombe esingezansi kukhona amapayipi okuhambisa umoya ohlanzekile kanye nezimbobo ezinde zokuhambisa umoya emaphasishi ekilasi.

Imishini yokufaka umoya eyahlukene

Ukusetshenziswa kwemishini yokungenisa umoya ehlukaniselwe kulungele ukuvuselela izikole, futhi ikilasi ngalinye lingena umoya ngokuzimela.Izikwele ezinombala okhanyayo odongeni olungaphandle esithombeni esingezansi ziyimishini yokungenisa umoya ehlukaniselwe indawo.

Ezinye izikole eJalimane nazo zinokutholwa kwekhwalithi yomoya kanye namadivayisi we-alamu, futhi umthamo womoya ungabuye ulungiswe ngokuya ngokugxilisa i-CO2.Ukwengeza, ukufakwa kokukhipha umoya okuningi eJalimane nakho kunamadivayisi okubuyisela ukushisa, nokusebenza kahle kokuthola ukushisa okungaphezu kuka-70%, nokugcizelela kakhulu ukonga amandla nokunciphisa ukukhishwa.
