Kodi tingatani kuti tikhale otetezeka m’ngozi ya migodi ya malasha yomwe imachitika kawirikawiri?

Mpaka 2020.12.5, anthu 122 afa m'migodi ya malasha m'dziko lonselo chaka chino, kupha kapena kutsekera anthu 224. Chaka chino, ngozi zazikulu zachitetezo cha migodi ya malasha (poyerekeza ndi 2019) zawonjezeka ndi imodzi, ndipo chiwerengero cha anthu omwe anamwalira chawonjezeka ndi anthu 16, kuwonjezeka kwa 50% ndi 44% motsatira." Chongqing Songzao "9.27" ngozi yamoto, anthu 16 amwalira. ndipo anthu 38 anavulala; Ngozi yamoto ya Chongqing Songzao "9.27" yachititsa kuti anthu 23 aphedwe ndi mgodi wa malasha. pansi pa mtima wanga.

Pambuyo pa kusanthula kofunikira, chifukwa cha ngozi yamoto ya Chongqing Songzao "9.27" ndi Downhole No. Pambuyo pa kutentha kwa lamba kumakwera. Chifukwa cha kulephera kwa chipangizo chotetezera kutentha ndi chojambulira utsi chomwe chinayikidwa pa conveyor lamba, panalibe chenjezo kapena kuyimitsidwa kwa ntchito ya lamba. Zinapangitsa kuti lambawo aziyaka moto ndipo malasha a pa lambawo amayaka. Mipweya yapoizoni ndi yovulaza yomwe imapangidwa ndi kuyakako idzabwereranso kumalo ogwirira ntchito, kuchititsa kuti anthu awonongeke.

Malamulo oteteza chitetezo m'migodi ya malasha amati kuchuluka kwa mpweya wa carbon monoxide mumlengalenga m'migodi ya malasha sikuyenera kupitirira 0.0024%, ndipo mpweya wa monoxide udzapangidwa pamene mafunde a malasha ayaka mwadzidzidzi kapena moto wapansi panthaka ukachitika. Tonse tikudziwa kuti poizoni wa carbon monoxide ndi woopsa kwambiri. Mpweya wa carbon monoxide ukakokera m’thupi la munthu, umaphatikizana ndi hemoglobin m’thupi la munthu, kenako n’kupanga carboxyhemoglobin. Zitha kupangitsa hemoglobin m'thupi la munthu kutaya ntchito ndi kunyamula mpweya, motero zimatha kuyambitsa hypoxia ndi asphyxia. Ngozi zambiri za m'migodi ya malasha zimakhala zambiri koma kutulutsa kapena kutayikira kwa mpweya wapoizoni monga carbon monoxide kwadzetsa chiphe kwa ogwira ntchito komanso ngozi zakupha. Chifukwa chake, pakuwunika kwathu kwachitetezo chatsiku ndi tsiku, tiyenera kusamala kwambiri ndi magwiridwe antchito ndi magwiridwe antchito a utsi wautsi, ma alarm a carbon monoxide ndi zida zina kuti tipereke chitsimikizo cha chitetezo chathu.

HENGKO fixed co alamu ndi chipangizo chodziwira co, chimakhala ndi mwayi woyankha mwachangu, kukhudzika kwakukulu, kuthekera kolimba kotsutsana ndi kusokoneza komanso chitetezo cha IP65. Pamene kuchuluka kwa carbon monoxide kupitirira mtengo wokonzedweratu wa chipangizocho, chojambuliracho chimatumiza nthawi yomweyo chizindikiro cha alamu chomveka komanso chowoneka.

HENGKO CO sensor module ndi gawo la gasi lapadziko lonse lapansi lopangidwa ndikupangidwa ndikuphatikiza ukadaulo wowunikira ma electrochemical ndi gawo lovuta. Chigawochi chimagwira ntchito ndi dera losavuta loyendetsa, lomwe lili ndi digito yotulutsa ndi kutulutsa kwamagetsi a analogi, kukhazikika kwabwino komanso moyo wautali. Zotsatira zoyezera zimatha kuwerengedwa kuchokera ku microprocessor kudzera pa mawonekedwe a I2C.

Kuphatikiza pa alamu yokhazikika ya carbon monoxide, HENGKO ilinso ndi achojambulira cham'manja cha gasizomwe zimatha kuzindikira mosalekeza kuchuluka kwa mpweya umodzi. Chojambuliracho chimagwiritsa ntchito sampuli zapampu kuti zizindikire mpweya, ndipo wogwiritsa ntchito amatha kusankha ndodo yoyenera malinga ndi zofunikira zosiyanasiyana za chilengedwe, zomwe zimapangitsa kuti muyeso ukhale wosavuta. Chiwonetserocho chimakhala ndi chiwonetsero chachikulu cha madontho a OLED, chomwe chimawonetsa kukhazikika, kuchuluka komanso nthawi yomwe gasi akuyezedwa. Njira yosavuta ya makiyi atatu ndi chidziwitso chatsatanetsatane chimapangitsa kuti ntchitoyi ikhale yachidule komanso yosavuta kumvetsetsa.
