Imodyuli ephathwayo ye-UVC Led yaManzi aqukuqelayo yokuNcincisa inzalo iphuhliswe ngempumelelo

Ukuze koyiswe ingxaki yeebhaktheriya emanzini, iimveliso zokubulala iintsholongwane zamanzi okusela emarikeni ikakhulu yi-ultraviolet (UV) inzala. Ngokomahluko wobude bamaza, i-ultraviolet inokwahlulwa ibe yi-ultraviolet A (UVA), i-ultraviolet B (UVB) kunye ne-ultraviolet C (UVC), phakathi kwayo i-UVC inefuthe elinamandla lokuvala inzala. Okwangoku, amaziko ophando eJamani, eJapan, eUnited States, eKhanada nakwezinye iindawo aphuhlisa ubugcisa obunxulumene nokuvala inzala kwe-UVC.

Kwiminyaka yakutshanje, i-LED ijongene nolwandle olubomvu lokhuphiswano lwamaxabiso, kwaye i-UVC yokubulala iintsholongwane kunye nokuthengisa inzala isetyenziswa ngokubanzi. Nangona kunjalo, itekhnoloji esele ikhona ye-UVC yesihluzi samanzi yokucoca isihluzi sokukhanya isaxhomekeke kwisibane semercury ukuvelisa inzala ye-UVC. Ayinkulu kuphela kwivolumu kunye ne-ethe-ethe kwityhubhu yesibane, kodwa iphinde ithande ukungcoliseka kwe-mercury kunye nomonakalo omkhulu kwindalo. Iingcali ezikhokelwayo ezivela kwiZiko loPhando lwezoShishino laseTaiwan ziye zabandakanyeka kuphando olunxulumene ne-LED ixesha elide, ke zifuna ukuqala ngomthombo wazo wokukhanya we-LED wokufumana izisombululo ezingcono zolu shishino.

Ukuphuhlisa umthombo wokukhanya we-UVC ye-LED, kufuneka siqale sijongane nendlela yokukhetha ubude obuchanekileyo be-UVC kumthombo wokukhanya we-LED, kwaye sizame impembelelo yamaqela ahlukeneyo kwiintsholongwane phakathi kwe-UVC 200nm kunye ne-280nm, ukuze sifumane i-spectrum ngokuhambelana nokufunxa. Emva koko kufuneka sijongane nendlela yokudlala indima yokuvala inzala kunye nokwandisa ukukhanya kwe-UVC, okubandakanya ukuyilwa kwendlela. Ngoko ke, iqela lophando lakha umjelo apho ukuhamba kwamanzi kunokutshatyalaliswa kakhulu ngumthombo wokukhanya kwe-UVC kwindawo encinci, kwaye iphucula ubuninzi be-UVC ye-projected inlet flow channel, enethemba lokufezekisa ukuhamba kwamanzi kwiilitha ze-2 ngomzuzu kwaye Ukuphelisa ngaphezu kwe-99.9% ye-E. coli, Phumelela eyona mpembelelo ibalaseleyo yokuvala inzala. Iqela lityale imali kwi-R & I-D idityaniswe nabavelisi abaninzi be-LED eTaiwan, ngokuthe ngcembe yaseka ikhonkco lemizi-mveliso elizimeleyo eliphakamileyo, eliphakathi kunye nelisezantsi le-UVC elikhokelela eTaiwan, kwaye lenze imarike yolwandle oluluhlaza.

"Imodyuli ephathwayo ye-UVC ekhokelwa yi-module yokucoca amanzi" nayo idluliselwe ngempumelelo kubavelisi. Kulindeleke ukuba zidweliswe ekupheleni kuka-2018, ukuze iintsapho ezininzi zikwazi ukonwabela imithombo yamanzi acocekileyo. Kwixesha elizayo, inokusetyenziswa kumashishini afaka ukubaluleka okukhulu kumgangatho wamanzi, njengeshishini le-biomedical kunye neshishini le-aquaculture. Ngethuba nje i-UVC iholele imodyuli yokucoca amanzi ehambayo ifakwe kwindawo yokungena kunye nokuphuma kwamanzi, umgangatho wamanzi unokuphuculwa ngakumbi. Okwangoku, ngenxa yobukhulu bayo obuncinci kunye nokufakwa lula, obu buchwepheshe bunokuqhutywa kwaye bufakwe ngokukhawuleza kumanzi ngamnye. indawo yokuphuma. Ayifanelekanga kuphela kumakhaya aqhelekileyo, kodwa ingasetyenziselwa ukuphendula ngokukhawuleza kwiindawo zentlekele. Ngokomzekelo, kwimeko yenyikima okanye ezinye iintlekele, le mveliso yokucoca amanzi inokubonelela ngokukhawuleza abantu ngamanzi omileyo, acocekileyo nakhuselekileyo. Le teknoloji iphinde ifakwe kwi-2018 ye-2018 ye-world top 100 yesayensi kunye neteknoloji. UZhu Mudao, umlawuli we-Institute of electro-optical systems ye-Industrial Research Institute, wathi ngophuhliso olunjalo lwezobuchwepheshe, asikwazi ukugcina iindleko kuphela, kodwa kwakhona. lahla izithintelo ekusebenziseni.
