Lab aminci mai ƙonewa guba gas ganowa ƙararrawa mafita

A ranar 18 ga Disamba, 2015, kusan karfe 10:10 na safe, an yi fashewar wuta a dakin gwaje-gwaje na bene na biyu na Sashen Sunadarai na Jami'ar Tsinghua, wanda ya haifar da hayaki mai ƙarfi, an karya gilashin da ke kusa da ɗakin kuma ya kashe wani mai gwaji na post-doctoral. Sakamakon binciken ya nuna cewa dalilin da ya haifar da fashewa ne saboda zubar da kwalliyar hydrogen, wanda ya haifar da zafi mai zafi wanda ya haɗu da kayan ƙonewa wanda ya haifar da babbar wuta. Fashewar dakin gwaje-gwaje tana faruwa kusan kowace shekara, wanda ya sake nuna matsalolin amincin gas na dakin gwaje-gwaje.

Yawancin jami'o'i da dakunan gwaje-gwaje na kimiyya saboda buƙatun gwajin su, ana amfani da nau'ikan reagents daban-daban, da yawa suna da guba, gas mai ƙonewa. Ma'aikatan dakin gwaje-gwaje suna da motsi mai yawa, amfani da su sau da yawa, idan rashin cikakken tsarin gaggawa yana da sauƙin haɗarin tsaro.

Misali, manyan dalilin wannan hatsarin hydrogen gas, hydrogen gas ne dakin gwaje-gwaje, kimiyya bincike raka'a yau da kullun amfani da gas, da yawa amfani da gas silinda ajiya, gas silinda sanye da bawul, matsin lamba ma'auni, kwararar ma'auni, idan a cikin dakin gwaje-gwaje kafin ko bayan amfani da karshe, wadannan dubawa wuri ba muhimmanci, zai haifar da hydrogen gas zuba, idan ba a sanye da mai ƙonewa gas gano ƙararrawa tsarin, fuskantar bude wuta zai haifar da fashewa.

Duk abin da dakin gwaje-gwaje, kimiyya bincike na rukunin gwaji yanayin da ya shafi guba da cutarwa gas, mai ƙonewa gas, duk suna buƙatar shigar da mai ƙonewa, guba gas gano ƙararrawa. Mai ƙonewa, guba gas gano ƙararrawa shigar a gas zubar da haɗari yankin, kamar gas silinda ajiya yankin, gwaji aiki yankin, da dai sauransu, dangane da girman yankin yanke ƙayyade adadin shigarwa.

Gas ganowa ƙararrawa iya upload filin gas mataki darajar zuwa mai sarrafawa ko sarrafawa cibiyar, ta atomatik haske ƙararrawa lokacin da mai ƙonewa, guba gas zuba, tunatar da ma'aikata don daukar matakai a kan lokaci. Tsarin kuma za a iya haɗa shi da tsarin fitar da iska na dakin gwaje-gwaje don maye gurbin fitar da iska ta atomatik. Tsarin tsari kamar haka:
