I-Hielscher Ultrasound Technology

I-Ultrasonic Emulsions ye-Water-in-Diesel Combustion

Ama-generator kagesi, izinjini zemikhumbi nezinjini zesitimela, eziphethwe ngudizili, zingaqhutshwa kahle uma kusetshenziswa amanzi emulsion yedizili. Amafutha e-diesel emulsion anciphisa ukusetshenziswa kukawoyela, ehlise izinga lokushisa lokushisa, ashise izihlanza futhi anciphise ukuphuma, njenge-NOx no-soot. I-Ultrasonic emulsation iyindlela ethembekile, elula futhi ephumelelayo yokukhiqiza uwoyela osezingeni eliphakeme lamanzi udizili.

I-Ultrasonic Emulsization ye-Amanzi-ku-Diesel

Ama-emulsions we-Water-in-Diesel (i-WiDE; W / D emulsion fuel) iyindlela eguquliwe yamafutha edizili, equkethe aze afike ku-15% wamanzi. Yaziwa nangokuthi i-aqua-petrol, kuma-emulsions wamanzi-udizili, amaconsi amanzi akhiqizwa nge-ultrasonic emulsion eqhubekayo yedizili. I-sonication enkulu ye-ketshezi ikhiqiza i-acoustic cavitation. Amandla we-Cavitational Shear Force aphazamisa ukuphonswa kwamatshe futhi akhiqize i-emulsion engenangqondo yamanzi angenakuvinjezelwa amanzi kanye nezigaba zikadizili.

Emulsion ye-Water-in-Diesel

I-WiDE (W / D emulsion) ichazwa njengokuhlanganiswa kwezinto ezingamanzi zemvelo zamaconsi amanzi (abahlakazekile / isigaba sangaphakathi) kudizili (isigaba esiqhubekayo / sangaphandle). Umenzeli we-emulsifying ungezwa ngokugxila okuphansi ukuze uthuthukise ukuqina kwe-emulsions futhi wehlise isidingo sokuxuba samandla.

Emulsion Yesigaba Esimbili

I-emulsion enezigaba ezimbili ichaza ingxube yamanzi edizili ngaphandle kokusebenzisa noma yimuphi umuntu owenza i-survivant. Kwi-WiDE enezigaba ezimbili, ukusakazwa kwamanzi nokudla udizili kukhushulelwa phezulu ngaphambili kwenjini. I-emulsion emincane enezimbiza ezimbili ezisebenzisa amanzi edonsa ngodizili ihamba ngqo isuka kumphumela we-ultrasonic flow-cell ungene enjini yokugibela. Ngaphandle kokusebenza ngokweqile, i-emulsion ayenzelwe ukugcina isitoreji, kodwa ukugcwala okuqondile.

Case Study of Amanzi-Diesel Emulsion Amafutha

Isethaphu

Ithnin et al. (I-2018) ifunde ngomphumela ka-in-dizeli emulsion uphethiloli (iWiDE) kwisilinda esisodwa, enjini yokufaka udizili eqondile. Amanzi nodizili bekugcinwa amayunithi ahlukene, kuwo kuye kudluliselwe ngobuningi bawo ohlelweni lokuxuba. Uhlelo lokuxuba luqukethe inhlanganisela ye-high shear mixer ne-homogenizer ye-ultrasonic. Umxube we-shear unikeze ukuxubha okungaxutshiwe kwamanzi nodizili, ngenkathi i-sonication isetshenziselwa i-emulsion enosayizi omnandi. I-emulsion yedizili yamanzi ilungiswe ngamanzi ayi-5%. Uphethiloli we-homogenible we-WiDE udluliselwe ngqo kusuka ohlelweni lokuxubha wangena enjini. Amafutha weWiDE alungiselelwe awazange aqukethe noma yini, ngalokho abizwa ngokuthi uphethiloli we-emulsion wesikhathi eside (UW / D). Injini yedizili ihlolwe ngaphansi kwezimo zomthwalo ezihlukene ezine (1 kW (25%), 2 kW (50%), 3 kW (74%), 4 kW (100%) nangejubane elingaguquki lika-3000 rpm. Ukuze uqhathanise imiphumela efana nokusebenza kukaphethiloli nokukhipha igesi, kufakwe ugesi we-emulsion (i-emulsion ozinzile (i-SW / D)) nophethiloli we-diesel ohlanzekile (i-D2) nakho kuhlolwe kunjini efanayo. 5% wamanzi usetshenziselwa i-emulsion engazinzile kanye ne-emulsion ezinzile.

Imiphumela

Ukuhlolwa kwenjini kukhombisa ukuthi uphethiloli odonsa ngodizili wamanzi ngaphandle kwe-survivant (UW / D) uphumela ekuphuculeni okukhulu kwenjini ngokunyuka okulinganiselwa ku-3.59% ekusebenzeni kwama-brake thermal ufanisi (BTE) kanye nokwehliswa ngo-3.89% ekusebenzeni kwe-brake ethize (BSFC) njengoba kuqhathaniswa ukucoca uphethiloli. Amafutha we-emulsion, womabili azinzile (i-SW / D) futhi ongazinzanga (i-UW / D), akhuphula ukusebenza kahle kwe-enjini ngenxa yento encane eqhumayo. Into eqhuma kakhulu ibangela ukuhwamuka okusheshayo kwamaconsi amanzi okushukumisayo. Njengoba amaconsi amanzi emincane azungezwe uwoyela, inqubo yokuhwamuka kakhulu iphazamisa amaconsi ngobudlova abe izinhlayiya ezinhle kakhulu, ezikhuthaza ukuxubana komoya nophethiloli. Ukuphazamiseka kwamaconsi nokuxuba nomoya kukhulisa ukusebenza kahle komlilo kakhulu.
Imiphumela ikhombisa ukuthi umqondo wokukhiqiza nokudlulisela uphethroli we-emulsion wamanzi ngesikhathi sangempela enjini ngaphandle kokusebenzisa i-survivant usebenza kahle kakhulu. Ukuhanjiswa ngokushesha kwenhlanganisela yedizili enamanzi elungiswa nge-ultrasonic kususa inkinga yokuzinza kaphethiloli e-emulsion egcinwe kanye nokuthembela kuma-survivant. Amafutha we-diesel emulsion engavikeleki (UW / D) alondoloze ngokuqinile ifomu lawo le-emulsion ngaphandle kokufinyelela esigabeni sokudonsa ngaphakathi kwe-25sec (bheka isithombe ngezansi).

I-Ultrasonic emulsation iyindlela ethembekile yokukhiqiza i-emulsifier-free-in-diesel emulsion fuels.

Ukuziphatha kweDroplet kaphethiloli we-ater-in-dizeli emulsion ngemuva kwesikhathi a) 10 s, b) 25 s, c) 50 s no d) 132 s. (ukukhulisa i-1000 ×) – Ithnin et al. 2018

Uma kuqhathaniswa nophethiloli ococekile we-dizeli, uphethiloli osebenzisa amanzi edonsa ngodizili unokuncipha okukhulu kokukhipha i-nitrogen oxides (NOx) kanye ne-factor particle (PM) ngokuncishiswa okuphakathi kuka-31.66% no-16.33% ngokulandelana.

Sekukonke, ama-emulsions alungiselelwe ngokweqile – ukufakwa kwe-wether kuyashukumiseka noma kuzinze ngumuntu osebenza ngokweqile – asize ukonga uphethiloli, futhi anciphise ukuphuma kwomoya.

Yini Eyenza Amafutha eWiDE Asebenze Kakhulu? – I-Micro-Explosion Phenomenon

Amafutha e-Water-in-Diesel emulsion afaka izinhlayiya zamanzi ezimisiwe esigabeni sokuqhubeka sedizili. Lapho esehlanganiswe, amaconsi amanzi asosayizi omncane kaphethiloli we-emulsion afinyelela esiteji sawo esishisayo ngokushesha kunodizili futhi adale ukuqhuma komoya wokuqhuma (ukuqhuma okuzenzakalelayo) ngesikhathi sokuhlangana, kwakheka izinhlayiya ezinhle kakhulu. Ngenxa yendawo yokwanda yezinhlayiya zemizuzu ehlanganiswe nomoya wokudla, umoya kanye nokuxubana kaphethiloli kuthuthukiswa kakhulu futhi kwandise ukusebenza kahle kwalokho komlilo.
