Ubuchwepheshe bokwenza i-Metal powder

Ukusungulwa kuhlobene nendlela kanye nenqubo yokulungisa impushana yensimbi nge-atomization

Ubuchwepheshe bangemuva

Ngawo-1820, i-atomization yomoya yayisetshenziselwa ukwenza izimpushana zensimbi ezingezona ayoni, futhi ngawo-1950 nawo-1960, yayisetshenziswa kabanzi ukukhiqiza izimpushana zensimbi nengxubevange Ngasekupheleni kwawo-1970 nasekuqaleni kwawo-1980, ngokuthuthukiswa kobuchwepheshe bamakhompiyutha kanye nobuchwepheshe besimanje bokulawula, i-atomization yangena esikhathini sokuthuthuka okunamandla. Njengamanje, uhlelo oluvamile lwe-atomization yegesi ukusebenzisa igesi eliwuketshezi, njenge-nitrogen ewuketshezi, i-argon ye-liquid, emva kokushisa kwe-gasification, kusetshenziswa igesi yokushisa ephezulu yokucindezela okuhloswe ku-metal liquid, i-atomization yensimbi ibe yizinhlayiya. Manje i-atomization yegesi iwukusebenzisa kakhulu igesi engasebenzi, noma umoya onomfutho ophezulu, njll., okubi ukusuka kugesi ongenayo igesi ukuya oketshezini bese kuba yingcindezi, kukhushulwe izindleko, kanye nezinto zokuhamba eziyingozi.

Ukusungulwa kuhloswe ukunikeza indlela yokulungisa i-metal powder nge-atomization, futhi ixazulula inkinga yezindleko eziphezulu zokulungiselela i-metal powder nge-atomization. Ukuze kuxazululwe inkinga yezobuchwepheshe, ukusungulwa kunikeza indlela yokulungiselela i-metal powder nge-atomization, ehlanganisa izinyathelo ezilandelayo: i-atomizer enguketshezi ishisa futhi ifakwe umoya ukuze ithole i-atomizer yegesi, lapho, i-atomizer iwuketshezi emkhathini we-10 â ° c-30 â ° C, kanti impushana yensimbi itholakala ngokudlula i-atomizer ye-atomizer. i-atomization yegesi yoketshezi lwensimbi. Umuthi owenziwe nge-athomu yinto enephuzu elibilayo ebangeni lika-50 ° C kuya ku-200 ° C. Lapho, i-nebulizer iyi-ethanol noma i-nebulizer iyingxube ye-ethanol namanzi. I-atomizer ingamanzi, futhi ngaphambi kokuba i-atomizer ewuketshezi icindezelwe, ishisiswe futhi ifakwe igesi kusengaphambili, i-atomizer ihlanganisa nezinyathelo ezilandelayo: ukudidiyela nokukhipha umoya-mpilo, ukuhlanza nokukhipha amanzi aluhlaza, ukuthola amanzi ahlanzekile ahlanzekile. Amanzi aluhlaza yinoma yimaphi amanzi asempompini, emanzini olwandle noma emanzini acwecwe. I-atomization yegesi yoketshezi lwensimbi ihlanganisa: Ngengcindezi engekho ngaphansi kuka-1.1 mpa futhi ekushiseni okungengaphansi kwendawo yokubilisa ye-atomizer, uketshezi lwensimbi lukhishwa yi-atomizer ehwamuziwe.

Lapho, ngemva kokuba uketshezi lwensimbi luyigesi i-athomu futhi impushana yensimbi itholakala, inqubo yokunciphisa impushana yensimbi ihlanganisa nezinyathelo ezilandelayo. Lapho, ngemva kwe-atomization yegesi yoketshezi lwensimbi ukuze kutholwe impushana yensimbi, i-atomization yegesi ekhishwe kuthreyi ye-atomization spray iyatholwa. Ukusungulwa kwamanje kunikeza indlela yokulungisa izimpushana zensimbi ngokufaka i-atomizing into enguketshezi emkhathini we-10 â ° C kuya ku-30 ​​â ° C, ama-aerosol aveza isimo se-liquid. Uma kuqhathaniswa negesi ye-inert kanye ne-nitrogen enegesi ekushiseni okujwayelekile nokucindezela, okusunguliwe akudingi ukwenza uketshezi lwe-athomu kusuka esimweni segesi, ngaleyo ndlela kunciphisa izindleko zokuthola uketshezi lwe-athomu; Emazingeni okushisa ajwayelekile nokucindezela, i-atomizer iwuketshezi, ngakho-ke ukuthuthwa kwengcindezi ephezulu akudingekile ngesikhathi sokuhamba, okunciphisa izindleko zokuhamba kanye nobungozi be-atomizer. Ukufingqa, indlela yokulungisa impushana yensimbi nge-atomization ehlinzekwe ukusungulwa inganciphisa kakhulu izindleko zezinto ezibonakalayo ze-atomu, ngaleyo ndlela yehlise izindleko zokulungisa i-powder yensimbi. Ukunikeza isithombe esicacile sohlelo lobuchwepheshe lokuqanjwa noma ubuciko bangaphambili, incazelo emfushane yemidwebo edingekayo ukuze isetshenziswe ekufanekisweni noma incazelo yobuciko yangaphambilini inikezwe ngezansi, imidwebo enamathiselwe echazwe ngezansi ingenye yezindlela zokusungulwa kwamanje, neminye imidwebo enamathiselwe ingatholwa ngaphandle komsebenzi wokudala wochwepheshe abajwayelekile kulo mkhakha. Fig.

U-1 ubonisa umdwebo wokugeleza wendlela yokulungisa impushana yensimbi nge-atomization, futhi umdwebo 2 ubonisa umdwebo wesakhiwo sendawo wombhoshongo we-atomization.

Ukuze wenze abantu abasemkhakheni wezobuchwepheshe baqonde kangcono uhlelo lokusungulwa, okulandelayo kuchazwa ngokuningiliziwe ngemidwebo enamathiselwe kanye ne-embodiment ethize. Ngokusobala, i-embodiments echazwe iyingxenye kuphela ye-embodiments yokusungulwa, hhayi konke. Ngokusekelwe ekufanekisweni kokusunguliwe, zonke ezinye izifanekiso ezitholwe ochwepheshe abajwayelekile emkhakheni ngaphandle kokwenza umsebenzi wokudala ziwela ngaphakathi kwendawo yokuvikela okusunguliwe. Njengoba kuboniswe ku-Fig. 1, fig. I-1 inikeza umdwebo wokugeleza wendlela yokulungisa i-powder yensimbi nge-atomization ehlinzekwe ekufanekisweni kokusungulwa, okungase kuhlanganise: Isinyathelo S1: Ukukhishwa kwangaphambili kwe-atomizer ewuketshezi ngaphansi kwengcindezi, ukuthola i-atomizer yegesi. I-nebulizer kulokhu kufanekiswa isho into enguketshezi emazingeni okushisa ajwayelekile kanye nengcindezi. Ikakhulukazi, kungaba into ewuketshezi emkhathini ka-10 â ° C kuya ku-30 ​​â ° C. Isinyathelo S2: i-atomizer eyigesi yethulwa kuthreyi ye-atomizing spray, futhi uketshezi lwensimbi luba negesi ukuze kutholwe impushana yensimbi.

Kufanele kuqashelwe ukuthi, njengoba igesi isetshenziselwa ukwenza i-athomu yensimbi ewuketshezi, isimo segesi se-atomizer kufanele sigcinwe lapho singeniswa kuthreyi yokufutha; ngaphezu kwalokho, lapho i-atomizer isetshenziselwa ukwenza i-atomize yensimbi ewuketshezi, i-atomizer isetshenziselwa ukufafaza insimbi ewuketshezi ngokucindezelwa okuphezulu, okufana ne-atomization evamile ukulungisa impushana yensimbi. Njengoba kuboniswe emkhiwaneni. 2, umd. 2 inikeza umdwebo wohlelo lwesakhiwo sendawo sethreyi yesifutho se-atomizing ye-embodiment yokusungulwa. Enqubweni yokwenza i-atomization yensimbi, uketshezi lwensimbi 2 lwehla lusuka endaweni olungaphezulu kwepuleti lokufutha le-atomization 1; ngesikhathi esifanayo, igesi ye-atomization ifafazwa nge-jet channel 3 ezinhlangothini zombili zoketshezi lwensimbi 2 olugeleza phansi, umthelela ukhiqizwa oketshezini lwensimbi 2, olukhiqiza insimbi eyimpuphu. Iningi lamagesi ane-athomu asetshenziswayo njengamanje i-nitrogen noma amanye amagesi angasebenzi. Kodwa le gesi ekuthuthweni kwezimboni ngokuvamile idingeka ukuthi iphole phansi kuqala icindezelekile ibe uketshezi, ekushiseni okuphansi kanye nokuthutha kwengcindezi ephezulu. Okokuqala, kubiza kakhulu ukucwilisa i-nitrogen ewuketshezi noma igesi ye-inert ewuketshezi enegesi ezingeni lokushisa elivamile nokucindezela, futhi kubiza futhi ukugcina i-nitrogen ewuketshezi ifakwe uketshezi ngesikhathi sokuthutha, umphumela uba ukuthi izindleko ze-atomizer ziyanda, okuholela ezindlekweni eziphakeme zempushana yensimbi. Ekusungulweni kwamanje, into enguketshezi emazingeni okushisa ajwayelekile kanye nokucindezela isetshenziswa ngokuqondile njenge-atomizer, futhi kulula ukuyithola kunento enegesi ezingeni lokushisa elijwayelekile nokucindezela, futhi engadingi ukucwilisa into, ukusungulwa kunciphisa izindleko zokuthengwa kwe-atomizer, futhi ayidingi ukusebenzisa umfutho ophezulu kanye nokuhamba kwezinga lokushisa eliphansi kwinqubo yokuthutha. Ngakho-ke, i-atomizer esetshenziswe ekusungulweni inganciphisa kakhulu izindleko zokuthola i-atomizer, ngaleyo ndlela yehlise izindleko zokulungiselela i-metal powder nge-atomization.

Ngokuzithandela, ekufanekiseni okuthile kokusungulwa, i-atomizer ingaba amanzi, i-ethanol, noma ingxube yamanzi ne-ethanol, phakathi kokunye. Uma ucabangela ukuthi atomization of metal powder ekulungiseleleni, isidingo sokugcina ukuhwamuka the atomization. Ngakho-ke, ukuze kwehliswe izindleko zokuhwamuka kwama-aerosol oketshezi abe ama-aerosol anegesi, izinto ezinephuzu eliphansi lokubilisa zingasetshenziswa njengama-aerosol. Yiqiniso, kuyaqondakala ukuthi iphuzu layo lokubilisa akufanele libe liphansi kakhulu, ngaphandle kwalokho liyashintshashintsha. Ngakho-ke, kwesinye isimo esiqondile sokusungulwa, into e-athomu ingase ihlanganise into enephuzu elibilayo ebangeni lika-50 ° C kuya ku-200 ° C. Yiqiniso, i-nebulizer enephuzu lokubilisa ephakeme ayibandakanyi ekusungulweni, futhi i-nebulizer enephuzu elibilayo lika-50 ° C-200 ° C ku-embodiment ekhethiwe, i-embodiment ekhethiwe kakhulu. ukuhwamulisa uketshezi lwe-athomu. Kokunye ukubonakaliswa okuqondile kokusungulwa, i-atomizer ingaba amanzi. Kufanele kuqashelwe ukuthi intengo yamanzi iphansi uma kuqhathaniswa nezinye izinto. Izindleko ze-atomizer zingancishiswa ngezinga elikhulu. Ngaphezu kwalokho, amanzi asetshenziswa njenge-atomizer kulomfanekiso angase abe amanzi atholakala kalula njengamanzi olwandle, amanzi ompompi, noma amanzi acwecwe. Ngaphandle kwalokho, ukuze kugwenywe ukungcola emanzini, amanzi angase ahlanganise:

Amanzi aluhlaza ahlanzwa nge-distillation, inzalo kanye ne-deionization ukuze athole amanzi ahlanzekile ahlanzekile. Amanzi awuketshezi asetshenziswa njenge-atomizer ukuze kulungiswe impushana yensimbi ngokusebenzisa i-atomization yomsebenzisi ngemva kokufakwa kwe-gasification, okungavimbela ngempumelelo izinhlayiya zokungcola emanzini, umoya-mpilo nokunye kusuka ku-oxidation kuya ensimbi. Ngaphezu kwalokho, ukuze ugweme i-oxidation engenakugwenywa ye-powder yensimbi etholiwe ngesikhathi senqubo yokulungiselela, ngemva kokuthola i-powder yensimbi, ingase ihlanganise nokwelashwa kwe-powder yensimbi ngokusabela kokunciphisa. Ikakhulukazi, i-metal powder ingabuye ixutshwe nokunciphisa igesi ukukhiqiza ukusabela kokunciphisa ngaphansi kwezimo ezithile zokusabela, futhi ekugcineni bathole impushana yensimbi ehlanzekile. Ngokusekelwe ekufanekisweni komuntu ngokungafanele, kokunye ukufana okuqondile kokusungulwa, ukusungulwa kungase kuhlanganise: Ngengcindezi engekho ngaphansi kuka-1.1 mpa futhi engekho ngaphansi kwezinga lokushisa lephuzu elibilisayo le-atomizer, insimbi ye-liquid i-atomizer e-atomizer e-vaporized. Ngokukhethekile, lapho i-atomizer enegesi ihwamuka kunsimbi ewuketshezi, kuqinisekiswa ukuthi i-atomizer ayincibiliki. Ngakho-ke, kuyadingeka ukwenza i-atomization yensimbi ekushiseni okuphezulu kanye nemvelo yokucindezela okuphezulu. Ikakhulukazi, i-atomization ingenziwa ngengcindezi ephakeme kuno-1.1 mpa nasezingeni lokushisa elingaphezu kwendawo yokubilisa ye-atomizer. Kufanele kuqashelwe ukuthi ukucindezela okungengaphansi kuka-1.1 mpa kungase kusetshenziswe embodiments lapho i-atomizer ingamanzi, kodwa ingcindezi engu-0.6 mpa noma 0.7 mpa ingase isetshenziswe ezintweni ezifana ne-ethanol.

Ngokuzikhethela, kwenye i-embodiment ethize yokusungulwa, kungase kuphinde kubandakanye: kulandela i-atomization yegesi ephezulu yokucindezela koketshezi lwensimbi, ukuthola impushana yensimbi, ama-aerosols egesi akhishwe kuthreyi yokufutha ayatholwa. Ngenxa yokuthi i-atomizer iwuketshezi ekushiseni okuvamile nokucindezela, lapho i-atomizer yegesi ikhishwa ku-atomizer yokushisa ephezulu kanye ne-high-pressure, izinga lokushisa nokwehla kwengcindezi, i-atomizer ingancibilika ibe uketshezi. Kulula ukugaywa kabusha kunezinto ezinegesi, ngaleyo ndlela konga izindleko. Ama-embodiments kule ncazelo achazwa ngendlela eqhubekayo. I-embodiment ngayinye igqamisa umehluko kwezinye izifaniso. Izingxenye ezifanayo noma ezifanayo ze-embodiment ngayinye zidluliselwa komunye nomunye. Ngomshini oveziwe we-embodiment, incazelo ilula ngoba ihambisana nendlela eveziwe ye-embodiment, njengoba kuchazwe esigabeni sezindlela. Indlela yokulungiselela i-metal powder nge-atomization ehlinzekwe ngokusungulwa kwethulwa ngokuningiliziwe. Kuleli phepha, isimiso nokuqaliswa kokusungulwa kuchazwa ngezibonelo ezithile, ezisetshenziselwa ukusiza ukuqonda indlela kanye nomqondo wayo oyinhloko. Kufanele kuphawulwe ukuthi okusunguliwe kungathuthukiswa futhi kuguqulwe ngaphandle kokuhlukaniswa nomgomo wokusungulwa kwabasebenzi abajwayelekile bezobuchwepheshe emkhakheni wezobuchwepheshe, lezi zinguquko kanye nokuguqulwa nakho kuwela ngaphansi kokuvikelwa kwezimangalo zokusungulwa.
