I-Coulter Air Lifter ye-Cellulose Ether Industry

Isiphakamisi somoya sohlobo lwe-coulter esikwazi ukusebenza ngokuqhubekayo siklanyelwe, esisetshenziswa kakhulu njengemishini yokomisa i-dealcoholization ohlelweni lokukhiqiza i-cellulose ether ngendlela ye-solvent, ukuze kubonakale ukusebenza okuphumelelayo nokuqhubekayo kwenqubo yokomisa i-dealcoholization, futhi ekugcineni uqaphele. inhloso yokukhiqizwa kwe-CMC. Ukusebenza okuqhubekayo.

Amagama angukhiye: i-carboxymethyl cellulose ether (i-CMC ngamafuphi); ukusebenza okuqhubekayo; i-colter air lifter

0,Isandulelo

Enqubweni yendabuko yokukhiqiza i-cellulose ether ngendlela ye-solvent, umkhiqizo ongahluziwe we-carboxymethyl cellulose (ngemuva kwalokhu ebizwa ngokuthi i-CMC) etholwe ngokusabela kwe-etherification ingatholwa ngezinqubo zokucwenga ezifana nokugeza kwe-neutralization, ukwelashwa okomisa, ukuchotshozwa kanye ne-granulation, njll. Ingxenye kuphela ye-ethanol equkethwe ku-CMC engahluziwe engenhla itholwa ngokufakwa emanzini kanye nosawoti wesodium ngesikhathi se-neutralization kanye nenqubo yokuwasha, kanti enye ingxenye ye-ethanol igcinwa ku-CMC engahluziwe, yomisiwe, iputshuziwe, igayiwe futhi ihlanganiswe ku-CMC ephelile. . sebenzisa kabusha. Eminyakeni yamuva nje, intengo yezinyibilikisi eziphilayo iqhubekile nokukhuphuka. Uma i-ethanol ingakwazi ukugaywa kabusha, ngeke ibangele ukumoshwa kwezinsiza kuphela, kodwa futhi ikhulise izindleko zokukhiqiza ze-CMC, okuzothinta inzuzo yomkhiqizo futhi kunciphise ukuncintisana komkhiqizo. Kulo mongo, abanye abakhiqizi be-CMC bathuthukisa ukugeleza kwenqubo futhi basebenzisa isomisi se-rake vacuum ngesikhathi sokudayiswa nokomisa, kodwa umshini wokomisa i-rake ungasebenza kuphela ngezikhathi ezithile, futhi umfutho wabasebenzi uphezulu, ongakwazi ukuhlangabezana nezidingo ze-vacuum dryer. ukukhiqizwa kwe-CMC ekhona. izimfuneko zokuzenzakalela. Ithimba le-R&D le-Zhejiang Provincial Research Institute of Chemical Industry lenze umshini wokukhumula umoya wohlobo lwe-colter wenqubo ye-CMC ye-decoholization kanye nenqubo yokomisa, ukuze i-ethanol isheshiswe futhi iguquguquke ngokuphelele emkhiqizweni ongahluziwe we-CMC futhi igaywe kabusha ukuze isetshenziswe, futhi ngesikhathi esifanayo. isikhathi sokuqedela ukusebenza kwenqubo yokomisa ye-CMC. Futhi ingabona ukusebenza okuqhubekayo kokukhiqizwa kwe-CMC, futhi iyimishini ekahle yokufaka esikhundleni se-rake vacuum dryer kwinqubo yokukhiqiza ye-CMC.

1. Uhlelo lokuklama lwe-colter air lifter yemboni ye-cellulose ether

1.1 Izici zesakhiwo se-colter air lifter

Isiphakamisi somoya sohlobo lwe-coulter sakhiwe ngokuyinhloko indlela yokudlulisa, umzimba wejakhethi yokushisisa evundlile, ingxenye yegeja, iqembu lommese ondizayo, ithange lokukhipha umoya, indlela yokukhipha amanzi kanye nombhobho wesitimu nezinye izinto ezibalulekile. Le modeli ingafakwa ngedivayisi yokudla endaweni yokungena kanye nedivayisi yokukhipha ekuphumeni. I-ethanol eshibhile ikhishwa ngethangi le-exhaust futhi igaywe kabusha ukuze isetshenziswe, ngaleyo ndlela ibona ukusebenza okuqhubekayo kokukhiqizwa kwe-CMC.

1.2 Umgomo wokusebenza we-colter air lifter

Ngaphansi kwesenzo se-colter, i-CMC yomkhiqizo ongahluziwe iyanyakaza eduze kodonga lwangaphakathi lwesilinda endaweni eyisiyingi kanye ne-radial ngakolunye uhlangothi, futhi iphonswe ngendlela evamile yezinhlangothi ezimbili ze-colter ngakolunye uhlangothi; lapho impahla ye-block enyakazayo igeleza ngommese ondizayo, Iphinde yahlakazwa ngamandla ngommese ophenduphendukayo onesivinini esikhulu. Ngaphansi kwesenzo esihlanganisiwe se-coulters nemimese endizayo, umkhiqizo ongahluziwe we-CMC uphendukiswa ngokushesha futhi ugaywe ukuze kwandiswe indawo engaphezulu lapho i-ethanol ingashiswa khona; ngesikhathi esifanayo, izinto eziku-cylinder zishiswa yi-steam yejazi futhi umusi udluliselwa ku-cylinder ukuze ushise ngokuqondile impahla Ngaphansi kokusebenza kabili kwe-ethanol, ukusebenza kahle kwe-volatilization kanye nomphumela we-ethanol kuthuthukiswa kakhulu, futhi I-ethanol ihlukaniswa ngokushesha futhi kahle. Ngesikhathi esifanayo se-dealcoholization, isitimu esisejazini sishisisa impahla kusilinda futhi siqedele inqubo yokomisa ye-CMC. emva kwalokho. I-CMC ngemuva kokwenziwa kwe-dealcoholization nokomiswa ingangena kunqubo elandelayo yokuchotshozwa, i-granulation kanye nokupakishwa komkhiqizo ngemva kokukhishwa endleleni yokukhipha.

1.3 Isakhiwo esikhethekile se-colter kanye nokuhlelwa

Ngocwaningo lwezimpawu ze-CMC, abacwaningi bakhethe ukusebenzisa i-colter mixer eyakhiwe ekuqaleni njengemodeli eyisisekelo, futhi bathuthukisa ukwakheka kwesakhiwo kanye nokuhlelwa kwe-colter ye-colter izikhathi eziningi. Ibanga phakathi kwama-coulter amabili asondelene ekuqondeni kwe-circumferential I-engeli efakiwe ithiα, α ingama-degrees angu-30-180, ahlelwe ngokuzungeza ku-shaft eyinhloko, futhi isiphetho esingemuva se-colter sine-arc concave ukuze kuthuthukiswe amandla okufafaza kwezinto ngendlela evamile yezinhlangothi ezimbili ze-colter, ukuze impahla ijikijelwa futhi ichotshozwe ngangokunokwenzeka ukuze kwandiswe indawo engaphezulu lapho i-ethanol ingashintshashintsha khona, ukuze ukukhishwa kwe-ethanol kumkhiqizo ongahluziwe we-CMC kwanele.

1.4 Idizayini ye-aspect ratio yesilinda

Ukuze kuqashelwe ukusebenza okuqhubekayo kwesiphakamisi somoya, ubude bomphongolo bude kunalobo bomxube ojwayelekile. Ngokuthuthuka okuningana ekwakhiweni kwesilinganiso sobude nobubanzi bomzimba owenziwe lula, isilinganiso esifanele sobude ukuya kobubanzi bomzimba owenziwe lula satholwa ekugcineni, ukuze i-ethanol iguquguquke ngokugcwele futhi ihlinzekwe ethangini lokukhipha umoya. isikhathi, kanye nokusebenza kwenqubo yokomisa ye-CMC kungaqedwa ngesikhathi esifanayo. I-CMC ngemuva kokwenziwa kwe-dealcoholization kanye nokomisa ingena ngqo enqubweni yokuchoboza, i-granulation kanye nokupakishwa komkhiqizo, iqaphela ukuzenzekelayo komugqa ogcwele wokukhiqiza kwe-CMC.

1.5 Ukuklanywa kwemibhobho ekhethekile

Kukhona umlomo wombhobho okhethekile ngaphansi kwesilinda ukuze uqhunyiswe ngesitimu. I-nozzle ifakwe isiphethu. Lapho isitimu singena, umehluko wengcindezi wenza ikhava yombhobho ivuleke. Uma isitimu singagelezi, ikhava yombhobho ivala umlomo ngaphansi kokushuba kwesiphethu ukuvimbela ukukhishwa kwe-CMC engahluziwe. I-Ethanol ivuza ku-nozzle.

2. Izici ze-colter air lifter

Isiphakamisi somoya sohlobo lwe-coulter sinesakhiwo esilula nesinengqondo, singakhipha i-ethanol ngokushesha futhi ngokugcwele, futhi singabona ukusebenza okuqhubekayo kwenqubo yokomisa i-CMC dealcoholization, futhi iphephile futhi kulula ukuyifaka, ukuyisebenzisa nokuyinakekela. Amanye amakhasimende anikeze impendulo ngemuva kokuyisebenzisa. Ukusebenzisa lo mshini akugcini nje ngokuba nezinga eliphezulu lokubuyisela i-ethanol kanye nokusetshenziswa kwamandla okuphansi, kodwa futhi kuthuthukisa ikhwalithi yomkhiqizo, kunciphisa izindleko zokukhiqiza, futhi konga izinsiza ze-ethanol. Ngesikhathi esifanayo, ithuthukisa kakhulu izimo zokusebenza kanye nokukhiqiza kwabasebenzi, futhi ihlangabezana nezidingo ezikhona ze-CMC. Izidingo ezizenzakalelayo zokukhiqiza izimboni.

3. Amathemba okufaka isicelo

Eminyakeni yamuva nje, imboni yezwe lami ye-CMC iyashintsha kusukela ekukhiqizeni okudinga abasebenzi abaningi iye ekukhiqizeni okuzenzakalelayo, ithuthukisa ngenkuthalo ucwaningo lwemishini emisha nokuthuthukiswa, futhi ngokuqhubekayo ithuthukisa inqubo ngokuhambisana nezici zemishini, ukuze ifeze ukukhiqizwa kwe-CMC ngezindleko eziphansi. futhi ulungise imikhiqizo esezingeni eliphezulu. Umgomo ofanayo wamabhizinisi okukhiqiza e-CMC. Isiphakamisi somoya sohlobo lwe-coulter sihlangabezana kakhulu nale mfuneko futhi siyisinqumo esihle semishini yamathuluzi yokukhiqiza ye-CMC.
