Aikace-aikacen Sensors na Gas a cikin Maganin Hatsarin Ciwon Gas

1. An yi amfani da shi don saka idanu mai ƙonewa da ƙararrawa

A halin yanzu, haɓakar kayan haɓakar gas ya sanya na'urori masu auna iskar gas tare da haɓakar haɓaka, aiki mai ƙarfi, tsari mai sauƙi, ƙaramin girman, da ƙarancin farashi, kuma ya inganta zaɓin zaɓi da ƙwarewar firikwensin.Ƙararrawar iskar gas ɗin da ta wanzu galibi suna amfani da tin oxide tare da na'urori masu auna ƙarfe masu mahimmanci na gas, amma zaɓin ba shi da kyau, kuma daidaiton ƙararrawar yana shafar sakamakon guba mai ƙara kuzari.Hankali na semiconductor gas-m kayan da gas yana da alaƙa da zafin jiki.Hankali yana ƙasa da zafin jiki.Yayin da zafin jiki ya tashi, hankali yana ƙaruwa, yana kaiwa kololuwa a wani zazzabi.Tun da waɗannan kayan da ke da iskar gas suna buƙatar cimma mafi kyawun hankali a yanayin zafi mafi girma (yawanci fiye da 100 ° C), wannan ba kawai yana cinye ƙarin wutar lantarki ba, amma yana iya haifar da gobara.

Ci gaban na'urori masu auna iskar gas ya magance wannan matsala.Misali, na'urar firikwensin iskar gas da aka yi da yumbu mai ƙoshin iskar gas na ƙarfe na iya haifar da firikwensin gas tare da babban hankali, kwanciyar hankali mai kyau, da wani zaɓi na zaɓi ba tare da ƙara ƙirar ƙarfe mai daraja ba.Rage zafin aiki na semiconductor gas-m kayan, da inganta su ji na ƙwarai a dakin zafin jiki, ta yadda za su iya aiki a dakin zafin jiki.A halin yanzu, baya ga yumbun ƙarfe oxide ɗin ƙarfe guda ɗaya da aka saba amfani da shi, an ƙirƙira wasu keɓaɓɓun ƙarfe oxide semiconductor gas mai kula da tukwane da gauraye tukwane na ƙarfe oxide gas.

Sanya firikwensin iskar gas a wuraren da ake samar da iskar gas mai ƙonewa, fashewa, mai guba da cutarwa, adanawa, jigilar su, da kuma amfani da su don gano abubuwan da ke cikin iskar cikin lokaci da kuma gano hatsarori da wuri.An haɗa na'urar firikwensin iskar gas tare da tsarin kariya, ta yadda tsarin kariya zai yi aiki kafin iskar gas ya kai iyakar fashewa, kuma za a kiyaye asarar haɗari zuwa ƙananan.A lokaci guda, ƙananan ƙarancin da rage farashin na'urori masu auna iskar gas sun sa ya yiwu a shiga gida.

2. Aikace-aikace a cikin gano gas da kuma kula da haɗari

2.1 Gano nau'ikan gas da halaye

Bayan hatsarin yabo da iskar gas ya faru, tafiyar da lamarin zai mayar da hankali ne wajen yin samfura da gwaje-gwaje, gano wuraren gargadi, tsara yadda za a kwashe mutane a wuraren da ke da hadari, ceto wadanda suka kamu da guba, toshewa da kuma lalata su, da dai sauransu. rage barnar da ma'aikatan ke haifarwa sakamakon yabo, wanda ke buƙatar fahimtar gubar iskar gas ɗin da aka zubar.Yawan gubar iskar gas yana nufin zubar da abubuwan da za su kawo cikas ga al'adar jikin mutane, ta yadda za a rage karfin mutane wajen tsara matakan da za su iya magancewa da kuma rage raunuka a cikin hatsarori.Ƙungiyar Kariyar Wuta ta Ƙasa ta raba gubar abubuwa zuwa nau'i masu zuwa:

N\H=0 A yayin da gobara ta tashi, ban da abubuwan kone-kone na gaba daya, babu wasu abubuwa masu hadari a cikin gajeren lokaci;

N\H=1 Abubuwan da zasu iya haifar da haushi da kuma haifar da ƙananan raunuka a cikin ɗan gajeren lokaci;

N\H=2 Babban maida hankali ko bayyanawa na ɗan gajeren lokaci na iya haifar da nakasu na ɗan lokaci ko saura rauni;

N\H=3 Bayyanar ɗan gajeren lokaci na iya haifar da mummunan rauni na ɗan lokaci ko saura;

N\H=4 Bayyanawa na ɗan gajeren lokaci yana iya haifar da mutuwa ko rauni mai tsanani.

Lura: Ƙimar N\H mai guba da ke sama ana amfani da ita kawai don nuna girman lalacewar ɗan adam, kuma ba za a iya amfani da shi don tsabtace masana'antu da kimanta muhalli ba.

Tun da gas mai guba zai iya shiga jikin mutum ta hanyar tsarin numfashi na ɗan adam kuma ya haifar da rauni, dole ne a kammala kariyar aminci da sauri lokacin da ake magance hatsarori masu guba.Wannan yana buƙatar ma'aikatan kula da haɗari don fahimtar nau'in, guba da sauran halayen iskar a cikin ɗan gajeren lokaci bayan isa wurin da hatsarin ya faru.
Haɗa array ɗin firikwensin iskar gas tare da fasahar kwamfuta don samar da tsarin gano iskar gas mai hankali, wanda zai iya gano nau'in iskar gas cikin sauri da kuma daidai, ta yadda za a gano gubar iskar.Na'urar gano iskar gas mai hankali ta ƙunshi tsarar firikwensin gas, tsarin sarrafa sigina da tsarin fitarwa.Ana amfani da yawancin na'urori masu auna firikwensin gas tare da halaye daban-daban na hankali don samar da tsararru, kuma ana amfani da fasahar tantance ƙirar hanyar sadarwa ta jijiyoyi don gano iskar gas da saka idanu kan haɗakar gas.A lokaci guda kuma, nau'in, yanayi, da gubar iskar gas na gama gari, masu cutarwa, da masu ƙonewa ana shigar da su cikin kwamfuta, kuma ana tattara tsare-tsaren magance haɗari gwargwadon yanayin iskar gas da shigar da kwamfuta.Lokacin da hadarin yayyo ya faru, tsarin gano iskar gas mai hankali zai yi aiki bisa ga hanyoyin da ke biyowa:
Shigar da rukunin yanar gizon → adsorb samfurin gas → firikwensin gas yana haifar da sigina → siginar gano kwamfuta → nau'in gas ɗin fitarwa na kwamfuta, yanayi, guba da tsarin zubar da ruwa.
Saboda tsananin na'urar firikwensin iskar gas, ana iya gano shi a lokacin da iskar gas ya yi ƙasa sosai, ba tare da yin zurfin zurfafa cikin wurin da hatsarin ya faru ba, ta yadda za a guje wa illar da ba dole ba saboda rashin sanin halin da ake ciki.Yin amfani da sarrafa kwamfuta, ana iya kammala aikin da ke sama da sauri.Ta wannan hanyar, ana iya ɗaukar ingantattun matakan kariya cikin sauri da kuma daidai, za a iya aiwatar da tsarin zubar da kyau, kuma ana iya rage asarar haɗari zuwa mafi ƙarancin.Bugu da kari, saboda tsarin yana adana bayanai game da yanayin iskar gas na gama-gari da tsare-tsaren zubar da ruwa, idan kun san nau'in iskar gas a cikin ruwa, zaku iya tambayar yanayin iskar gas da tsarin zubar da ruwa kai tsaye a cikin wannan tsarin.

2.2 Nemo ledoji

Lokacin da hatsarin yabo ya faru, ya zama dole a hanzarta nemo wurin zubar da ruwa kuma a ɗauki matakan toshewa da suka dace don hana haɗarin ci gaba da faɗaɗawa.A wasu lokuta, yana da wuya a sami ɗigogi saboda dogayen bututun mai, da ƙarin kwantena, da ɓoyayyun ɓoyayyiya, musamman lokacin da ɗigon ya yi haske.Saboda diffusibility na iskar gas, bayan iskar gas daga cikin akwati ko bututun mai, a karkashin aikin iska na waje da kuma maida hankali na ciki, ya fara yadawa a kusa da shi, wato, kusa da wurin zubar da ruwa, mafi girma yawan iskar gas.Dangane da wannan fasalin, amfani da na'urori masu auna iskar gas na iya magance wannan matsalar.Bamban da na’urar firikwensin hankali da ke gano nau’in iskar gas, iskar gas na wannan tsarin yana kunshe da na’urori masu auna iskar gas da yawa tare da overlapping sensitivity, ta yadda hankalin na’urar firikwensin ga wani iskar gas ya inganta, kuma ana amfani da kwamfutar. sarrafa gas.Canjin siginar sigina mai mahimmanci zai iya gano saurin tattarawar iskar gas, sannan nemo wurin ɗigo bisa ga canjin iskar gas.

A halin yanzu, haɗakar na'urori masu auna sigina na gas yana sa ƙaramin tsarin firikwensin ya yiwu.Misali, haɗe-haɗe na firikwensin ultrafine wanda kamfanin Japan ** ya haɓaka zai iya gano hydrogen, methane da sauran iskar gas, waɗanda aka tattara akan wafer silicon murabba'in mm 2.Hakazalika, haɓakar fasahar kwamfuta na iya sa saurin gano wannan tsarin cikin sauri.Don haka, ana iya haɓaka tsarin firikwensin wayo wanda yake ƙarami kuma mai sauƙin ɗauka.Hada wannan tsarin da fasahar tantance hoto da ta dace, yin amfani da fasahar sarrafa nesa na iya sanya shi kai tsaye shiga wuraren boye, wurare masu guba da cutarwa wadanda ba su dace da mutane su yi aiki ba, da kuma gano wurin da ya kwarara.

3. Bayanin ƙarshe

Ƙirƙirar sabbin na'urori masu auna iskar gas, musamman haɓakawa da haɓaka na'urorin gano iskar gas masu hankali, ta yadda za su iya taka rawar ƙararrawa, ganowa, ganowa, da yanke shawara mai hankali a cikin haɗarin hayaƙin iskar gas, haɓaka inganci da ingancin haɗarin iskar gas. handling.Tsaro yana taka muhimmiyar rawa wajen sarrafa asarar haɗari.

Tare da ci gaba da fitowar sabbin kayan da ke da iskar gas, hankalin na'urori masu auna iskar gas kuma an haɓaka cikin sauri.An yi imanin cewa nan gaba kadan, tsarin gano iskar gas mai kaifin basira tare da manyan fasahohin zamani za su fito, kuma za a inganta halin da ake ciki a halin yanzu na kula da hadarin iskar gas.
