Iyunithi yokubuyisela i-NMP eqandisiweyo

Ukusebenzisa amanzi okupholisa kunye neekhoyili zamanzi abandayo ukufunxa i-NMP emoyeni, uze emva koko ufumane ukubuyiselwa ngokuqokelela kunye nokucoca. Izinga lokubuyiselwa kwezinyibilikisi ezikhenkcezisiweyo lingaphezulu kwe-80% kwaye ubunyulu bungaphezulu kwe-70%. Uxinzelelo olukhutshwa emoyeni lungaphantsi kwe-400PPM, olukhuselekileyo, oluthembekileyo, kwaye olungabizi kakhulu; Uqwalaselo lwenkqubo lubandakanya: isixhobo sokubuyisela ubushushu (ukhetho), icandelo langaphambi kokupholisa, icandelo langaphambi kokupholisa, icandelo lasemva kokupholisa, kunye necandelo lokubuyisela; Imo yokulawula inokukhethwa kwi-PLC, ulawulo lwe-DDC, kunye nolawulo lonxibelelwano lwenkqubo; Inqanaba eliphezulu lokuzenzekelayo; Isixhobo ngasinye sokubuyisela kwakhona senzelwe inkqubo yolawulo oluzenzekelayo kunye nenkqubo yokudibanisa ukuqinisekisa imveliso ekhuselekileyo kunye nokusebenza kakuhle komatshini wokugquma kunye nesixhobo sokubuyisela kwakhona.

Iyunithi yokubuyisela i-Rotary NMP

Esi sixhobo sisetyenziswa kakhulu ekusetyenzisweni kwakhona kwe-N-methylpyrrolidone (NMP) eveliswa ekwenzeni iibhetri ze-lithium-ion. Ngexesha lenkqubo yokusetyenziswa kwakhona, igesi yenkunkuma yendalo eshushu kakhulu iqala idlule kwi-heat exchanger ukuze ibuyisele ubushushu obuthile kwaye inciphise ubushushu begesi yenkunkuma; Ipholisa ngakumbi ngaphambi kokuba ipholise ngee-coils zokupholisa ukuze idibanise igesi yenkunkuma yendalo kwaye ibuyisele inani elincinci le-condensate; Emva koko, emva kokudlula kwi-coil yokuqandisa, ubushushu begesi yenkunkuma yendalo buyancipha ngakumbi, kwaye ezinye izinyibilikisi eziphilayo ezixineneyo ziyafunyanwa; Ukuqinisekisa ukukhutshwa kwendalo, igesi yenkunkuma yendalo ekugqibeleni ixutywe ngevili lokuxinanisa ukuze ihlangabezane neemfuno zokusingqongileyo zegesi ye-exhaust ephuma emoyeni. Kwangaxeshanye, igesi ye-exhaust evuselelweyo nexutyiweyo idluliselwa kwi-coil yokufrijisa ukuze ijikeleze i-condensation. Emva komjikelo wokubhenela, uxinzelelo lwegesi ye-exhaust ephuma emoyeni lunokuba ngaphantsi kwe-30ppm, kwaye izinyibilikisi eziphilayo ezifunyenweyo nazo zingaphinda zisetyenziswe, okonga iindleko. Izinga lokubuyisa kunye nobunyulu bolwelo olufunyenweyo luphezulu kakhulu (izinga lokubuyisa lingaphezulu kwama-95%, ubunyulu bungaphezulu kwama-85%), kwaye uxinzelelo olukhutshwa emoyeni lungaphantsi kwama-30PPM,
Imo yokulawula ingakhethwa kwi-PLC, ulawulo lwe-DDC, kunye nolawulo lonxibelelwano lwenkqubo; Inqanaba eliphezulu lokuzenzekelayo; Isixhobo ngasinye sokurisayikilisha senzelwe inkqubo yolawulo oluzenzekelayo kunye nenkqubo yokutshixa ukuqinisekisa imveliso ekhuselekileyo kunye nokusebenza kakuhle komatshini wokugquma kunye nesixhobo sokurisayikilisha.

Iyunithi yokubuyisela i-NMP etshizwayo

Isisombululo sokuhlamba sixutywa sibe ngamathontsi amancinci nge-nozzle kwaye sitshizwe ngokulinganayo ezantsi. Igesi enothuli ingena isuka kwinxalenye esezantsi ye-spray tower ize ihambe iye phezulu ukusuka ezantsi ukuya phezulu. Ezi zimbini zidibana ngokuhamba okungasemva, kwaye ukungqubana phakathi kwamasuntswana othuli kunye namathontsi amanzi kubangela ukuba ajijeke okanye ahlangane, okwandisa kakhulu ubunzima bawo kwaye ahlale phantsi ngumxhuzulane. Uthuli olubanjiweyo luhlala phantsi ngumxhuzulane kwitanki yokugcina, lwenze ulwelo oluqinileyo oluphezulu ezantsi kwaye lukhutshwe rhoqo ukuze lunyangwe ngakumbi. Inxalenye yolwelo olucacisiweyo inokuphinda isetyenziswe, kwaye kunye nolwelo oluncinci olongezelelweyo olucacileyo, lungena kwi-spray tower ngepompo ejikelezayo esuka kwi-nozzle ephezulu ukuze kuhlanjwe ngokutshizwa. Oku kunciphisa ukusetyenziswa kolwelo kunye nobungakanani bonyango lwesibini lwelindle. Igesi ecocekileyo emva kokuhlamba ngokutshizwa ikhutshwa phezulu kwe-tower emva kokususa amathontsi amancinci olwelo athwalwa yigesi nge-demister. Ukusebenza kakuhle kokubuyisela i-N-methylpyrrolidone kwinkqubo yi-≥ 95%, uxinzelelo lokubuyisela i-N-methylpyrrolidone yi-≥ 75%, kwaye uxinzelelo lokukhupha i-N-methylpyrrolidone lungaphantsi kwe-40PPM.
