Iyunithi yokutakula i-NMP eqandisiwe

Ukusebenzisa amanzi okupholisa kanye nama-coil amanzi abandayo ukuhlanganisa i-NMP emoyeni, bese kutholwa ukululama ngokuqoqwa nokuhlanzwa. Izinga lokululama kwezinyibilikisi eziqandisiwe likhulu kuno-80% kanti ubumsulwa buphakeme kuno-70%. Ukuhlushwa okukhishelwa emkhathini kungaphansi kuka-400PPM, okuphephile, okuthembekile, futhi okungabizi kakhulu; Ukucushwa kwesistimu kufaka phakathi: idivayisi yokubuyisa ukushisa (ongakukhetha), ingxenye yangaphambi kokupholisa, ingxenye yangaphambi kokupholisa, ingxenye yangemuva kokupholisa, kanye nengxenye yokubuyisa; Imodi yokulawula ingakhethwa kusuka ku-PLC, ukulawula kwe-DDC, kanye nokulawula ukuxhumanisa izinqubo; Izinga eliphezulu lokuzenzakalela; Idivayisi ngayinye yokuvuselela kabusha yaklanywa ngesistimu yokulawula okuzenzakalelayo kanye nesistimu yokuxhumanisa ukuqinisekisa ukukhiqizwa okuphephile kanye nokusebenza okubushelelezi komshini wokumboza kanye nedivayisi yokuvuselela kabusha.

Iyunithi yokutakula ye-Rotary NMP

Le divayisi ivame ukusetshenziselwa ukuphinda kusetshenziswe i-N-methylpyrrolidone (NMP) ekhiqizwa ekukhiqizweni kwamabhethri e-lithium-ion. Ngesikhathi senqubo yokuphinda kusetshenziswe, igesi engcolile yezinto eziphilayo eshisa kakhulu iqala idlule ku-heat exchanger ukuze ibuyise ukushisa okuthile futhi inciphise izinga lokushisa legesi engcolile; Ukuphola okwengeziwe ngaphambi kokupholisa ngama-coil okupholisa ukuze kuhlanganiswe igesi engcolile yezinto eziphilayo futhi kubuyiselwe inani elincane le-condensate; Ngemuva kwalokho, ngemva kokudlula ku-coil eqandisayo, izinga lokushisa legesi engcolile yezinto eziphilayo liyancishiswa kakhulu, futhi kutholakale izinyibilikisi eziningi zezinto eziphilayo ezihlanganisiwe; Ukuqinisekisa ukukhishwa kwemvelo, igesi engcolile yezinto eziphilayo ekugcineni igxiliswa ngesondo lokuhlushwa ukuze ihlangabezane nezidingo zemvelo zegesi ekhishwa emoyeni ekhishwa emoyeni. Ngesikhathi esifanayo, igesi ekhishwa kabusha nehlanganisiwe idluliselwa ku-coil yokuqandisa ukuze kujikelezwe ukufiphala. Ngemva komjikelezo wokuthanda, ukuhlushwa kwegesi ekhishwa emoyeni ekhishwa emoyeni kungaba ngaphansi kuka-30ppm, futhi izinyibilikisi zezinto eziphilayo ezitholiwe nazo zingaphinde zisetshenziswe, kongiwe izindleko. Izinga lokululama kanye nobumsulwa boketshezi olutholiwe kuphezulu kakhulu (izinga lokululama lingaphezu kuka-95%, ubumsulwa bungaphezu kuka-85%), kanti ukuhlushwa okukhishelwa emkhathini kungaphansi kuka-30PPM,
Imodi yokulawula ingakhethwa kusuka ku-PLC, ukulawulwa kwe-DDC, kanye nokulawulwa kokuxhumanisa izinqubo; Izinga eliphezulu lokuzenzakalela; Idivayisi ngayinye yokuvuselela kabusha yakhelwe ngohlelo lokulawula oluzenzakalelayo kanye nohlelo lokukhiya oluxhumene ukuqinisekisa ukukhiqizwa okuphephile kanye nokusebenza kahle komshini wokumboza kanye nedivayisi yokuvuselela.

Iyunithi yokutakula ye-NMP efuthwayo

Isixazululo sokuwasha sihlanganiswa sibe amaconsi amancane nge-nozzle bese sifafazwa ngokulinganayo phansi. Igesi enothuli ingena isuka engxenyeni engezansi yombhoshongo wokufutha bese igeleza isuka phansi iye phezulu. Lezi ezimbili zihlangana ngokugeleza okuphambene, futhi ukushayisana phakathi kwezinhlayiya zothuli namaconsi amanzi kubangela ukuthi ziqine noma zihlangane, okwandisa kakhulu isisindo sazo futhi zihlale phansi ngamandla adonsela phansi. Uthuli olubanjiwe luhlala ngamandla adonsela phansi ethangini lokugcina, lwakha uketshezi oluqinile oluphezulu phansi futhi lukhishwe njalo ukuze kulungiswe okwengeziwe. Ingxenye yoketshezi olucacisiwe ingaphinde isetshenziswe, futhi kanye nenani elincane loketshezi olucacile olwengeziwe, ingena embhoshongweni wokufutha ngepompo ejikelezayo evela embhoshongweni ophezulu ukuze kuhlanzwe ngokufutha. Lokhu kunciphisa ukusetshenziswa koketshezi kanye nenani lokwelashwa kwendle yesibili. Igesi ehlanziwe ngemva kokuhlanza ngokufutha ikhishwa phezulu kombhoshongo ngemva kokususa amaconsi amancane oketshezi athwalwa yigesi nge-demister. Ukusebenza kahle kokubuyisa i-N-methylpyrrolidone ohlelweni kungu-≥ 95%, ukuhlushwa kokubuyisa i-N-methylpyrrolidone kungu-≥ 75%, kanti ukuhlushwa kokukhishwa kwe-N-methylpyrrolidone kungaphansi kuka-40PPM.
