Kuze kube ngu-2020.12.5, kube nokufa okungu-122 ezimayini zamalahle kulo lonke izwe kulo nyaka, kwabulala noma kwabamba abantu abangu-224. Kulo nyaka, izingozi ezinkulu zokuphepha ezimayini zamalahle (uma kuqhathaniswa no-2019) zikhuphuke ngoyedwa, kanti inani labashonile likhuphuke ngabantu abangu-16, ukwanda ngo-50% no-44% ngokulandelana." Ingozi yomlilo yaseChongqing Songzao "9.27", kwafa abantu abangu-16 kwathi abantu abangu-38 balimala; Ingozi yomlilo yaseChongqing Songzao "9.27" yabangela ukufa kwabantu abangu-23. Izimpilo eziningi ezintsha zimisiwe ngaphansi kwemayini yamalahle. Ngenkathi sikudalela lokhu, ukuphepha kokusebenza kwemayini yamalahle kufanele futhi kuvuselele ukunaka kwabantu futhi kushaye insimbi yokuxwayisa phansi kwenhliziyo yami.
Ngemva kokuhlaziywa okuyisisekelo, isizathu sengozi yomlilo iChongqing Songzao "9.27" ukucwilisa okukhulu kweDownhole No. 2, ukuguguleka okukhulu kwebhande lamalahle. Ngemva kokuba izinga lokushisa lebhande lenyukile. Ngenxa yokwehluleka kwedivayisi yokuvikela izinga lokushisa kanye nesitholi somusi esifakwe ku-conveyor yebhande, akukho sixwayiso noma ukumiswa kokusebenza kwebhande. Kwabangela ukuba ibhande libambe umlilo futhi kwabangela ukuba amalahle asebhandeni ashise. Amagesi anobuthi nayingozi akhiqizwa ukusha azobuyela endaweni yokusebenza, okubangela ubuthi kubasebenzi.
Imithethonqubo yokuphepha kwezimayini zamalahle ibeka ukuthi ukugcwala kwe-carbon monoxide emoyeni ezimayini zamalahle akumele kudlule u-0.0024%, futhi i-carbon monoxide izokhiqizwa lapho kushiswa amalahle ngokuzenzakalelayo noma lapho kuvela imililo engaphansi komhlaba. Sonke siyazi ukuthi ubuthi be-carbon monoxide buyingozi kakhulu. Ngemva kokuba i-carbon monoxide iphefumulelwe emzimbeni womuntu, izohlangana ne-hemoglobin emzimbeni womuntu, bese yakha i-carboxyhemoglobin. Ingenza i-hemoglobin emzimbeni womuntu ilahlekelwe umsebenzi kanye nomsebenzi wokuthwala umoya-mpilo, ngaleyo ndlela ingabangela i-hypoxia kanye ne-asphyxia. Izingozi eziningi zezimayini zamalahle ikakhulukazi ukukhiqizwa noma ukuvuza kwamagesi anobuthi njenge-carbon monoxide okubangele ubuthi kwabasebenzi kanye nezingozi ezibulalayo. Ngakho-ke, ekuhlolweni kwethu kokuphepha kwansuku zonke, kumelwe sinake kakhulu ukusebenza okuvamile kanye nokusebenza kwama-alamu omusi, ama-alamu e-carbon monoxide kanye neminye imishini ukuze sinikeze isiqinisekiso sokuphepha sokuphepha kwethu.
I-alamu ye-HENGKO fixed co iyithuluzi lokuthola i-co, inenzuzo yokuphendula okusheshayo, ukuzwela okuphezulu, ikhono eliqinile lokulwa nokuphazamiseka kanye nokuvikela kwebanga le-IP65. Lapho ukugcwala kwe-carbon monoxide kudlula inani elisethwe ngaphambilini lethuluzi, i-detector izothumela ngokushesha isignali ye-alamu ezwakalayo nebonakalayo.
Imodyuli yesenzwa ye-HENGKO CO iyimodyuli yegesi ebanzi eklanywe futhi yakhiqizwa ngokuhlanganisa ubuchwepheshe bokuthola i-electrochemical eyinkimbinkimbi nesekethe eyinkimbinkimbi. Le ngxenye isebenza nesekethe yokushayela elula, enokukhishwa kwedijithali kanye nokukhishwa kwe-voltage ye-analog, ukuzinza okuhle kanye nokuphila isikhathi eside. Umphumela wokulinganisa ungafundwa kusuka ku-microprocessor ngokusebenzisa isikhombimsebenzisi se-I2C somsebenzisi.
Ngaphezu kwe-alamu ye-carbon monoxide engaguquki, i-HENGKO nayo ine-alamuisitholi segesi esiphathwayo esiphathwa ngesandlaokungabona njalo ukuhlushwa kwegesi eyodwa. I-detector isebenzisa isampula yepompo ukuthola igesi, futhi umsebenzisi angakhetha induku efanelekile ngokwezidingo ezahlukene zemvelo, okwenza ukulinganisa kube lula kakhulu. Isikrini sisebenzisa isibonisi se-OLED dot matrix esikhulu sesikrini, esibonisa ngokubonakalayo ukuhlushwa, ububanzi kanye nesikhathi samanje segesi elinganiswayo. Imodi yokusebenza elula enamakhi amathathu kanye nesaziso solwazi oluningiliziwe kwenza ukusebenza kube kufushane futhi kube lula ukukuqonda.
