Kuvuga ko ibintu byinshi byabaye mumwaka kuva icyorezo cya COVID-19 gitangira, ibi ni ugusuzugura ibintu byabayeho, ku buryo bigoye kwibuka iminsi yambere yumuryango wibasiye ibyuma byakoreshaga misa -byakozwe na PPE reaction., Umuyaga ukorerwa murugo nibindi.Ariko, ntitwibuka ko habaye kugerageza cyane kubaka iyi DIY ya ogisijeni ya DIY mugice cyambere cyo kwaguka.
Urebye ubworoherane nibikorwa byubushakashatsi bwitwa OxiKit, birasa nkibitangaje kuba tutarabona ibikoresho nkibi.OxiKit ikoresha zeolite, imyunyu ngugu ishobora gukoreshwa nk'icyuma cya molekile.Udusaro duto twapakiye muri silinderi ikozwe mu miyoboro ya PVC no mu bikoresho biva mu bubiko bw'ibyuma, kandi bigahuzwa na compressor yo mu kirere idafite amavuta binyuze mu cyuma cyitwa pneumatike kiyobowe na valve nyinshi za solenoid.Nyuma yo gukonjesha mu muringoti wumuringa, umwuka wugarijwe uhatirwa kunyura mu nkingi ya zeolite ikunda kugumana azote mugihe yemerera ogisijeni kunyuramo.Umugezi wa ogisijeni wacitsemo ibice, igice kimwe cyinjira mu kigega cya buffer, ikindi gice cyinjira mu isohoka ry’umunara wa kabiri wa zeolite, aho hasohotse azote ku gahato.Arduino igenzura valve kugirango isimbuze gaze inyuma no kubyara litiro 15 za 96% ogisijeni nziza kumunota.
OxiKit ntabwo itezimbere nka generator yubucuruzi ya ogisijeni, ntabwo rero ituje cyane.Ariko ibi bihendutse cyane kuruta ubucuruzi, kandi kubantu benshi ba hackers, biroroshye kubaka.Ibishushanyo bya OxiKit byose ni isoko ifunguye, ariko bigurisha ibikoresho hamwe nibice bigoye-kugura ibice nibikoreshwa, nka zeolite.Tuzagerageza kubaka ikintu nkiki kuko ikoranabuhanga ni ryiza.Kugira isoko ya ogisijeni itemba cyane ntabwo ari igitekerezo kibi.
Litiro 15 kumunota bisa nkibitangaje.Ukurikije igipimo, birahagije gukomeza ubuzima bwabantu 7 mubihe bisanzwe (buri muntu @ litiro 2 kumunota).
Nahoraga nifuza kumenya uko iyi mirimo ikora.Birashimishije.Birasa nkaho kurenga ku mategeko ya thermodynamic, ariko siko bimeze.
Hamwe numubare munini wa ogisijeni wakozwe, ndashaka kumenya uko bizagenda uramutse umanitse uyu mwana kuri moteri yimodoka kandi / cyangwa ukagura.Irashobora kuba nka nitrite.Ibi bizaba bifite umutekano muke, kuko ushobora kubishyiraho kugirango ogisijeni "yera" yakozwe ihita ikoreshwa hafi ya moteri aho kubikwa ahantu hose.Ariko, nkeneye kubanza guhindura imodoka.Gusubira inyuma… “Bizaba bibi.”
Ntekereza ko ibi ari byiza gusudira / gushakisha / gukata ogisijeni / propane, ogisijeni / hydrogen cyangwa ogisijeni / acetylene.
Nibyo, nyuma yo kureba iyi videwo, YT yashyize ahagaragara amashusho yigitekerezo cya Dalbor Farny kumurongo wa O2.Ikigamijwe ni ugutanga urumuri rwa ogisijeni akeneye kugirango ikirahure gihuha umusarani.Kora ibyuma byawe byihariye bya digitale.Mubyukuri, batandatu muribo bahuriza hamwe kubyara 30 lpm O2.
Ndakeka moteri ya litiro 2 ikora ku bihumbi bike RPM ishobora gukoresha moteri ya litiro 15 aho kuba umunota 1.Ariko, ibi birashobora kongera urugero rwa ogisijeni mumyuka yo gufata kugeza kurwego ruhagije?mubyukuri ntubizi
Nitrite irashobora gutanga ingufu kuko irekura molekile ya azote kuri buri molekile ya nitrous yangiritse (ikomeza ubwinshi bwayo nkuko ogisijeni ikoreshwa), nkuko byongera ingufu za ogisijeni ikora neza (Kurekura nabyo bizatanga ubushyuhe).Kuvoma ogisijeni isukuye ntabwo aribyiza, kuko uracyatakaza amajwi kandi ugomba gukemura ibibazo bishobora gutwika moteri.
Uzakenera kwipimisha cyane.Moteri yimodoka ya litiro 2 ifite umuvuduko wa 2500 rpm "ihumeka" hafi metero kibe 2,5 yumuyaga kumunota (21% O²).Ni inshuro zigera kuri 600 z'umuntu uruhutse.Ingano y'ubuhumekero ikoreshwa n'abantu igera kuri 25% ya O², mu gihe ingano y'ubuhumekero ikoreshwa n'imodoka igera kuri 90%…
Itwika kandi piston zishyushye cyane kandi zashongeshejwe.Mugoreka lisansi ivanze, urashobora kubona imbaraga nyinshi kuri moteri iyo ari yo yose.Ariko piston izashonga kubera kwiyongera k'ubushyuhe.Umwuka wa ogisijeni wo hasi urinda icyuma gushonga.
Imodoka zisanzwe zisanzwe zibujijwe no guhumeka kandi bizatanga ingufu nyinshi mugihe zaka ogisijeni zose ziri mu kirere.Ibi bigerwaho mugukungahaza gato imvange, idatwika lisansi.Keretse niba ingufu ntarengwa zisabwa, moteri yimodoka isanzwe ikora gahoro gahoro, kubera ko ibikorwa bikungahaye kuri peteroli bivuze kugabanya ubukungu bwa peteroli no kongera umwanda wa hydrocarubone.
Niba ushaka gukoresha iyi mikorere kugirango wongere imbaraga, ukeneye uburyo bwo gushuka mudasobwa ya moteri kugirango wongere ijanisha runaka rya lisansi icyarimwe.
Niba ushobora kugumana igipimo cya lisansi ihoraho, birasa no gufungura akajagari kuri bike ku ijana.
Ariko, niba urenze "bike ku ijana" (kudasobanuka nkana…), urashobora kugera kumipaka yubushobozi bwa ECU bwo kumva umubare wumwuka winjira, cyangwa kugenzura uko lisansi isohoka, cyangwa ugashyiraho igihe cyo gutwika utitaye kumuvuduko. n'umwuka wo mu kirere urimo ukoresha.
Igipimo cyo gutembera gikenewe kugirango umuntu abeho biterwa ahanini nubuzima bwe!2 l / min biroroshye rwose.Abarwayi benshi bakeneye ubuvuzi bukomeye bakeneye 15 l / min.
Gusa witondere kubura ogisijeni.Ubwinshi bwa ogisijeni burashobora gutuma ibintu byinshi byaka kandi bigateza imbere gutwikwa kwamavuta menshi namavuta.Niyo mpamvu bakoresha compressor idafite amavuta.
Ibyo, hamwe nubundi buryo bwinshi "butahita butangiza" O2 uburyo bwo gutunganya burashobora kukubabaza, cyane cyane mukongera umuvuduko.
Niba ukina O2, urashobora gukoresha Mugenzi wa Oxygen Hacker wa Vance Harlow (abatwara nitrox bashobora kuba bafite uyu mugenzi): http://www.airpeedpress.com/newoxyhacker .html
Sinzi igitabo, ni umukoresha, ntabwo ari tuner.Ariko, urakoze kubisobanuro byawe, nzategeka kopi mugihe ifishi itangiye gukurikizwa!
Nibyo, nzabivuga.Uburyo bwo kunanirwa kwumwuka wa PVC ni uguturika kwa shrapnel, reba rero ibipimo byerekana umuvuduko-uko diameter yumuyoboro yiyongera, igipimo cyumuvuduko kizagabanuka.
Mu ntangiriro ya za 1980, nakoraga mu kigo gikodesha ibikoresho by'ubuvuzi byakodeshaga kandi bigatanga amashanyarazi ya Devilbiss.Muri kiriya gihe, ibyo bice byari bingana gusa na firigo ntoya.Ndibuka neza imiterere "ububiko bwibikoresho" imiterere yimbere.Ndacyibuka ko uburiri bwa sikeri bwakozwe numuyoboro wa PVC wa santimetero 4 no gutwikira, bityo imiterere yasobanuwe muri uyu mushinga ihuye n’ikoranabuhanga ryabanje (ariko biragaragara ko rifatika).
Compressor ni piston / diaphragm ya kabiri ihindagurika, kubwibyo rero nta mavuta aba mu kirere cyugarijwe.Umuyoboro uri mumutwe wa compressor ni urubingo ruto rutagira ingese.
Gutondeka imigezi bikorwa nigihe cyumukanishi, nta Arduino isabwa.Ingengabihe ifite syncronisation (moteri yisaha ya moteri) itwara igiti gifite ibiziga byinshi bya kamera.Micro ya micro igenda kuri kamera irasa valve ya solenoid, bigatuma gaze izenguruka.
Umwanzi ukomeye muri izo mashini ni ubuhehere bwinshi.Adorption ya molekile yamazi isenya uburiri bwa sikeri.
Mbere yuko mva mu kigo, twatangiye kubona intumbero yo guhatanira umunywanyi wa Devilbiss (ubu izina ntabwo nzi), kandi isosiyete yerekanye iterambere ryinshi.Usibye intumbero ntoya kandi ituje, uruganda rwanubatse uburiri bwa sikeri hakoreshejwe aluminium.Umuyoboro utwikiriwe nisahani ifite imashini zikozwe kuri O-impeta.Ndasa no gutekereza ku nkunga yuzuye-ihuza inteko.Ibyiza byiki gishushanyo nuko nibiba ngombwa, uburiri bushobora gutandukana kandi ibikoresho bya sikeri birashobora gusimburwa.Bakuyeho kandi igihe cyumukanishi babisimbuza ibikoresho byoroshye bya elegitoronike na SSRs kugirango batere solenoide.
Bakenera gukoresha imiyoboro ya SCH40 (umuvuduko wapimwe 260psi @ 3 ″) kandi bigaragara neza ko ifite 40psi yumutekano wumutekano hamwe na 20-30psi igenzura mbere yuko PVC ikandamizwa, bityo hakaba hari ikintu cyiza cyumutekano.Ntabwo uzi neza uburyo bizagerwaho na O2 Hindura ubukana.
Umuvuduko ukabije wa SCH40 ninshuro nyinshi umuvuduko wagenwe ukurikije diameter.Umuyoboro wa santimetero 3 ni psi 850, naho umuyoboro wa santimetero 6 ni 500 psi.1/2 santimetero yegereye 2000 psi.Kongera inshuro ebyiri za SCH80.Niyo mpamvu abatangiza tennis ya PVC badaturika-benshi.Kubagurira kuri chambre ya 6 cyangwa 8 ya santimetero bizongera amahirwe yawe.Ariko muri rusange, umuryango wa hackers ukunda gupfobya cyane imbaraga z ibirundo bya plastiki.https://www.
Nashaka gushimishwa no kugabanya ubushobozi bwabakunzi bwo gukoresha fireworks (kandi birashoboka ko ari ubuziranenge).Isoko ryo kwishimisha risanzwe rigura silinderi yubuvuzi yacyuye igihe.Icyo cyari igitekerezo cyanjye cya mbere, ariko ikiguzi cya kit + BOM cyarenze kure igiciro cyubuvuzi bwacyuye igihe.
Moteri yimodoka ya litiro 2 irashobora gukoresha litiro 9000 / umunota wa ogisijeni (umuvuduko mwinshi), bityo litiro 15 / umunota wa ogisijeni ni hafi 600., Iki nigikoresho gikonje.Naguze ibintu byinshi byavuguruwe bya litiro 5 kumunota kumadorari 300 buri umwe (igiciro gisa nkizamuka).Itanga litiro 5 / umunota.Watt amajana make arakoreshwa, nuko rero asubizwa hanze ko litiro 9000 kumunota (kubwimyidagaduro gusa) bisaba hafi kilo 360 (480 hp).
Kuberako algorithm yabo yanditswe nitsinda rya Berlin.(Kubara imwe uzabona inyenyeri ya zahabu.)
Reba kurubuga rwisosiyete… neza, ibisobanuro mububiko bwabo ntibisobanutse neza, ariko bazakugurisha ibiro 5 kumadorari 75.00.Reka rero turebe kuri github.Ntukore.Nta BOM ihari.
Dufite isoko ifunguye amashanyarazi ya elegitoronike ishobora kukubwira uko wayubaka aho kuyuzuza.Ndayise aha hantu amakuru yingenzi yabuze.Ninkaho imico itera ijisho… birashimishije.
OxiKit yavuze mu gitekerezo kuri imwe muri videwo zabo (imwe nahujije mu nkuru, ari yo IIRC) ko iyi ari sodium zeolite.
Kimwe nibindi bikoresho byose bya molekile, ubwira uwabikoze icyo ushaka kugikoresha, ntabwo aricyo kigamije.Kuberako arikintu kimwe, ariko aperture iratandukanye.
Ubusanzwe O2 ikoresha 13X zeolite 0,4 mm-0.8 mm cyangwa JLOX 101 zeolite, iyakabiri niyo ihenze cyane.Mugihe cyo kongera kubaka urutonde o2 rwibanze, nakoresheje 13X.Itara ryatsi rihora ryaka, bityo ubuziranenge bwa o2 nibura 94%.

5A (5 angstrom) ya molekile ya elegitoronike nayo irashobora gukoreshwa.Ndibwira ko bidahitamo azote, ariko birashobora gukoreshwa.
Hano hari animasiyo nziza kuri Wikipedia ishobora kugufasha muburyo bwihuse kugufasha kumva ihame ryakazi ryigikoresho: D desorption E umunaniro
Iyo inkingi ya zeolite yuzuye hafi ya azote, indangagaciro zose zirahindurwa kugirango zirekure azote yamamajwe ninkingi.
Urakoze cyane kubisobanuro byawe bigufi.Nahoraga nibaza niba generator ya azote ishobora gukoreshwa mumishinga DIY yo gusudira azote murugo.Kubwibyo, imyanda isohoka ya ogisijeni yibanze ni azote: itunganye, nzayikoresha muri sitasiyo yanjye idafite ibicuruzwa.
Mubyukuri, kubakunzi, ni byiza cyane gushobora guhindura umwuka muri ogisijeni yera cyane kandi azote nziza.Ndashaka kumenya niba ushobora gukoresha "ahanini azote" nka gaze ikingira gusudira.
Kuri TIG (izwi kandi nka GTAW), kubera ko plasma plume yunvikana cyane, sinzi neza.Gazi ya Argon ikoreshwa cyane cyane, rimwe na rimwe hamwe na gaze ya helium kugirango yinjire mubikoresho nka aluminium na titanium.Urujya n'uruza rugera kuri 6 kugeza 8l / min, rushobora kuba runini cyane kuri compressor isanzwe.
Mu gusudira, bigomba kuba ko ibirango nyamukuru byo gusudira byose bigurisha gaze ya azote ikingira umusaruro wa rohs, ariko igiciro cyibikoresho kiri hagati yama euro 1-2k.Igipimo cyacyo kigera kuri 1l / min, kibereye cyane kumashanyarazi.Reka rero dukusanyirize hamwe ibyuma hanyuma dukore ibicuruzwa bitagira flux bigurishwa murugo!
Abasudira bifuza gukoresha azote nziza nka gaze ikingira.Nibihendutse kuruta argon cyangwa helium ihendutse.Kubwamahirwe make, irakora kuburyo buhagije kubushyuhe bwageze kuri arc kandi ikunda gukora nitride itifuzwa muri weld.
Ikoreshwa mu gusudira gaze ikingira, ariko umubare muto gusa urashobora guhindura ibiranga gusudira.
Biragaragara, birashoboka kuyikoresha mugusudira laser, ariko na fab ifite ibikoresho byiza ntishobora kugira iyi mikorere.
Kubwibyo, mubitekerezo, byibuze PSA imwe irashobora gukoreshwa mukugabanya azote, hanyuma indi PSA (ikoresheje indi zeolite) kugirango igabanye ogisijeni, hasigara ibintu byinshi bitari ogisijeni cyangwa azote.
Iyo uvuze ukuri, icyo gihe, ndagusaba ko wahuza umwuka hanyuma ukayitandukanya kugirango utandukanye gaze ushaka / udashaka.
@ Foldi-A pointing point muburyo bwo kwinjiza ingufu nibisohoka.Nemera rwose ko imikorere izaba hejuru cyane murwego runini kuko ushobora gukoresha umwuka mubi mbere yo gukonja.
Ariko ku gipimo gito cyane, uzaba ufite compressor 1, iminara 4 ya zeolite hamwe nitsinda ryinshi ryumuvuduko wa elegitoronike hamwe nigiciro cyambere cyumugenzuzi uhendutse (Ubwonko), nkeka ko kizaba gito.
@irox irashobora kubigereranya nukuri, ariko ntamuntu ukoresha litiro 2 za ogisijeni azahita apfa / kwangirika atabonye ogisijeni.Kugereranya, abarwayi bacu bashinzwe ubuvuzi bukomeye (ICU) bafite umuvuduko mwinshi wa kabiri kubera COVID, babona 45-55L mugihe FIO2 ari 60-90%.Aba ni abarwayi bacu "bahamye".Niba nta soko ryinshi, byanze bikunze bizangirika vuba, ariko ntibazarwara kuburyo tuzaba intubated.Uzabona imibare isa cyangwa irenga kubandi barwayi ba ARDS cyangwa ibindi bihe byinshi bisaba urumogi runini kuruta urumogi rusanzwe.
Kuri njye, imikoreshereze ni niche.Ibi birashobora gushyira mu gaciro abarwayi 2 kumuvuduko wa 6-8 L, mubyukuri ni ahantu hashobora gutemba cyane hejuru ya kannula isanzwe cyangwa NIPPV.Ndashaka kuvuga ko ibi ari ingirakamaro cyane kubitaro bito bifite ogisijeni nkeya, kandi birashobora gutanga serivisi z'ubuvuzi ku barwayi bafite indwara zidakira mu bihe byihutirwa.
Ese umurwayi akoresha litiro 6 (cyangwa litiro 45-55) za ogisijeni ku munota, cyangwa yatakaye igice, ihumeka ibidukikije cyangwa ikindi kintu?
Amateka yanjye / uburambe ni sisitemu ntoya yo gufasha abantu bafite ubuzima bwiza (hamwe na karuboni ya dioxyde de carbone yakuweho na litiro zigera kuri 2 za karuboni ya dioxyde yongewe kumuntu kumunota), kubwibyo ukoresha umubare wubuvuzi, ibi birahumura amaso!
Ni ngombwa kwibuka ko bafata ogisijeni, kubera ko ibihaha byabo bigufi cyane iyo bafashe ogisijeni.Kubwibyo, ugereranije nibyifuzo bikenewe mumubiri wumuntu, ikiguzi ni kinini cyane, kuko mubyukuri, abantu bake cyane barinjira.
Sinzi niba umuntu wavuze ariwe wabiteguye, ariko ibi ntabwo bihuye nuburyo yabisobanuye.Amashanyarazi ya molekulari na zeolite ntabwo bifata N2, birashobora gutega O2.Kugira ngo ufate N2, ukeneye kwinjiza azote, ninyamaswa zitandukanye rwose.Amashanyarazi afata O2 mukibazo mugihe azote ikomeje kunyuramo.Ibi bigomba kuba bikwiye, kuko iyo urekuye igitutu ukagikoresha kugirango uta N2 muyindi nkingi, ntabwo byumvikana kugerageza gukuraho N2 hamwe na N2..Izi nigitutu cya swing adsorption ibice (PSA), bakora mugutega O2.Umuvuduko mwinshi hamwe na silinderi nini irashobora kuzana imikorere ihanitse (silinderi 4 ifite imikorere igera kuri 85%).Ibi bikora O2, ariko ntibikora nkuko abivuga (cyangwa ingingo ibivuga)
Ugomba gutanga amakuru asabwa, kubera ko ushobora rwose kwamamaza ads N2 kuri 13X na 5A zeolite ya molekile.http://www.phys.ufl.edu/REU/2008/reports/magee.pdf
Ingingo ya Wikipedia PSA yemeza kandi ko zeolite ikuramo azote.https://en.wikipedia.org/wiki/Igitutu_swing_adsorption#Process
Ati: “Icyakora, bihendutse cyane kuruta urwego rw'ubucuruzi.”Kubera ko BOM irenga $ 1.000, birangoye gushyigikira aya magambo.Inyemezabuguzi y'ibikoresho byo murugo (bidashobora gutwarwa) yibanda kubucuruzi bigura hafi 1/3, biroroshye kubibona, kandi ntibisaba akazi.Nzi ko 17LPM ari nziza, ariko ntamuntu uri hanze yibitaro uzasaba traffic nkiyi.Umuntu wese ufite icyo cyifuzo ari hafi kugenzura cyangwa kuba intubated.
Nibyo, uyu ni umushinga utuje, ariko yego, ikiguzi-cyiza nticyemewe kurwego runaka.Muri Ositaraliya, ibikoresho bishya 10l / pm ni amadorari 1500AUD gusa.Dufashe ko $ 1000 ari amadorari y'Amerika, ibi bigabanya ikiguzi cyo kugura ibikoresho bishya.
Mbere y'icyorezo, naguze imwe kuri eBay ku giciro cya £ 160 hamwe na litiro 1.5 ku munota ku giciro cya 98%.Kandi iki kintu kiratuje cyane kuruta iki!Muri ubu buryo, urashobora gusinzira rwose.
Ariko tumaze kubivuga, iyi ni imbaraga nini.Shyira mucyumba iruhande rw'umuyoboro muremure kugirango wirinde urusaku n'ibiza biturika…
Ndashaka kumenya niba bishoboka ko uyikoresha nkisoko ya azote yuzuye, mubidukikije bikingira cyangwa no gusudira?
Bite ho amapine yuzuye azote.Urebye amafaranga basaba muri iyi serivisi, azote igomba kuba ihenze cyane…
Intambwe ikurikira irashobora gushimisha-kubona ibisubizo byiyi concentration hanyuma utandukanye 95% O2 + 5% Ar ivanze.Ibi birashobora gukorwa no gutandukana kwa kinetic ukoresheje amashanyarazi ya CMS muri sisitemu ya PSA.Noneho shiraho pompe ya bar 150 kugirango wuzuze silinderi ya argon.
Noneho, dukeneye gusa umuntu ukora inzira ya Linde murugo kugirango twishimishe rwose
Ukoresheje urubuga na serivise, wemera byimazeyo gushyira mubikorwa byacu, imikorere hamwe na kuki yamamaza.Wige byinshi
