0,Intshayelelo

Kwinkqubo yemveli yokuvelisa i-cellulose ether ngendlela ye-solvent, imveliso ekrwada ye-carboxymethyl cellulose (emva koku ebizwa ngokuba yi-CMC) efunyenwe ngokuphendula kwe-etherification inokufumaneka ngeenkqubo zokucoca ezifana nokuhlanjwa kwe-neutralization, ukomisa unyango, ukutyumza kunye ne-granulation, njl. Kuphela inxalenye ye-ethanol equlethwe kwi-CMC ekrwada engentla ifunyanwa ngokuxutywa kunye netyuwa yesodium ngexesha lokungathathi hlangothi kunye nenkqubo yokuhlamba, kwaye enye inxalenye ye-ethanol igcinwa kwi-CMC ekrwada, yomisiwe, ixutywe, igranuliwe kwaye ipakishwe kwi-CMC egqityiweyo. . ricycle. Kwiminyaka yakutshanje, ixabiso le-solvents eziphilayo liye laqhubeka nokunyuka. Ukuba i-ethanol ayikwazi ukuphinda isetyenziswe, ayiyi kubangela inkunkuma yemithombo kuphela, kodwa ikhulise iindleko zokuvelisa i-CMC, eya kuchaphazela inzuzo yemveliso kunye nokunciphisa ukukhuphisana kwemveliso. Kulo mxholo, abanye abavelisi be-CMC baphucula ukuhamba kwenkqubo kwaye basebenzise isomisi seraki kwinkqubo yokucoca kunye nokomisa, kodwa isomisi se-rake vacuum sinokusebenza kuphela ngexesha elithile, kwaye ubungakanani bomsebenzi buphezulu, obungenako ukufezekisa iimfuno imveliso ekhoyo yeCMC. iimfuno ezizenzekelayo. Iqela le-R&D leZiko loPhando lwePhondo laseZhejiang leZiko loShishino lweMichiza liphuhlise i-colter-type air stripper ye-CMC dealcoholization kunye nenkqubo yokomisa, ukuze i-ethanol ikhawuleze kwaye iguqulwe ngokupheleleyo kwimveliso ekrwada ye-CMC kwaye ihlaziywe ukuze isetyenziswe, kwaye kwangaxeshanye. ixesha ukugqiba ukusebenza kwenkqubo yokomisa CMC. Kwaye inokuqonda ukusebenza okuqhubekayo kwemveliso ye-CMC, kwaye sisixhobo esifanelekileyo sokutshintsha isixhobo sokucoca iraki kwinkqubo yokuvelisa yeCMC.

1. Isikimu soyilo lwe-colter air lifter kushishino lwe-cellulose ether

1.1 Iimpawu zesakhiwo se-colter air lifter

Isiphakamisi somoya sohlobo lwe-coulter senziwe ikakhulu yindlela yothumelo, umzimba webhatyi yokufudumeza othe tyaba, isabelo sokulima, iqela lemela ephaphazelayo, itanki yokukhupha, indlela yokukhupha kunye nomphunga womphunga kunye nezinye izinto eziphambili. Lo mzekelo unokuxhotyiswa ngesixhobo sokutyisa kwindawo yokungena kunye nesixhobo sokukhupha kwi-outlet. I-ethanol eguquguqukayo ikhutshwa ngetanki yokukhupha kwaye iphinde isetyenziswe ukuze isetyenziswe, ngaloo ndlela iqonda ukusebenza okuqhubekayo kwemveliso ye-CMC.

1.2 Umthetho-siseko wokusebenza we-colter air lifter

Ngaphantsi kwesenzo se-colter, i-CMC yemveliso ekrwada i-turbulences ecaleni kodonga lwangaphakathi lwe-cylinder kwi-circumferential kunye ne-radial directions kwelinye icala, kwaye iphoswe kwicala eliqhelekileyo lamacala amabini e-colter kwelinye icala; xa izinto zebhloko ezishukumisayo zihamba ngemela ephaphazelayo, Iphinde yasasazwa ngamandla yimela ejikelezayo ejikelezayo. Ngaphantsi kwesenzo esidityanisiweyo se-coulters kunye neemela ezibhabhayo, imveliso ekrwada ye-CMC ijikeleziswa ngokukhawuleza kwaye ityunyuzwe ukunyusa indawo apho i-ethanol inokuguqulwa khona; Kwangaxeshanye, izinto ezikwisilinda zifudunyezwa ngumphunga wejacket kwaye umphunga ugqithiselwa kwi-cylinder ukutshisa ngokuthe ngqo izinto eziphathekayo Ngaphantsi komsebenzi ophindwe kabini we-ethanol, ukusebenza kakuhle kwe-volatilization kunye nesiphumo se-ethanol kuphuculwe kakhulu, kwaye I-ethanol ihlulwe ngokukhawuleza kwaye ngokucokisekileyo. Ngexesha elifanayo le-dealcoholization, i-steam kwijacket itshisa izinto kwi-cylinder kwaye igqibe inkqubo yokumisa ye-CMC. emva koko. I-CMC emva kwe-dealcoholization kunye nokomisa ingangena kwinkqubo elandelayo yokutyumza, i-granulation kunye nemveliso yokupakisha emva kokukhutshwa kwindlela yokukhupha.

1.3 Ubume obukhethekileyo kunye nolungiselelo

Ngophando kwiimpawu ze-CMC, abaphandi bakhetha ukusebenzisa i-colter mixer ephuhliswe kwinqanaba lokuqala njengemodeli esisiseko, kwaye baphucula ubume besakhiwo kunye nokuhlelwa kwe-colter ye-colter amaxesha amaninzi. Umgama phakathi kwee-coulters ezimbini ezikufutshane kwicala le-circumferential I-angle efakiweyo yiα, α yi-30-180 degrees, icwangciswe ngokujikelezayo kwi-shaft engundoqo, kwaye isiphelo esingasemva se-colter sine-arc concave yokuphucula amandla okutshiza kwezinto kunye nolwalathiso oluqhelekileyo lwamacala amabini e-colter, ukwenzela ukuba izinto eziphathekayo. iphoswe kwaye ityunyuzwe kangangoko kunokwenzeka ukwandisa indawo engaphezulu apho i-ethanol inokuguqulwa khona, ukuze ukukhutshwa kwe-ethanol kwimveliso ekrwada ye-CMC yanele ngakumbi.

1.4 Uyilo lwe-cylinder aspect ratio

Ukuze uqonde ukusebenza ngokuqhubekayo kwe-air lifter, ubude bombhobho bude kunomxube jikelele. Ngophuculo oluninzi kuyilo lomlinganiselo wobude ukuya kububanzi bomzimba owenziwe lula, owona mlinganiselo uphezulu wobude ukuya kububanzi bomzimba owenziwe lula wafunyanwa ekugqibeleni, ukuze i-ethanol ibe nokuguquguquka ngokupheleleyo kwaye inikezelwe kwitanki yokukhupha amanzi. ixesha, kunye nokusebenza kwenkqubo yokomisa yeCMC ingagqitywa ngaxeshanye. I-CMC emva kwe-dealcoholization kunye nokomisa ingena ngokuthe ngqo kwinkqubo yokutyumza, i-granulation kunye nokupakishwa kwemveliso, ukuqonda umgca opheleleyo we-automation yemveliso ye-CMC.

1.5 Uyilo lwemilomo ekhethekileyo

Kukho umbhobho okhethekileyo emazantsi e-cylinder ukwenzela ukutshisa. Umbhobho uxhotyiswe ngentwasahlobo. Xa umphunga ungena, umahluko woxinzelelo wenza ukuba isigqubuthelo somlomo sivuleke. Xa umphunga ungaphumi, isigqubuthelo somlomo sivala umlomo phantsi koxinzelelo lwasentlakohlaza ukuthintela ukukhutshwa kweCMC ekrwada. I-Ethanol ivuza emlonyeni.

2. Iimpawu zokuphakamisa umoya we-colter

Umphakamisi womoya wohlobo lwe-coulter unesakhiwo esilula nesinengqiqo, unokukhupha i-ethanol ngokukhawuleza nangokupheleleyo, kwaye unokuqonda ukusebenza okuqhubekayo kwenkqubo yokomisa i-CMC dealcoholization, kwaye ikhuselekile kwaye kulula ukuyifaka, ukusebenza nokugcina. Abanye abathengi banike ingxelo emva kokuyisebenzisa. Ukusebenzisa lo mshini awunayo kuphela isantya esiphezulu sokubuyisela i-ethanol extraction kunye nokusetyenziswa kwamandla aphantsi, kodwa nokuphucula umgangatho wemveliso, ukunciphisa iindleko zokuvelisa, kunye nokugcina izibonelelo ze-ethanol. Kwangaxeshanye, iphucula kakhulu iimeko zokusebenza kunye nemveliso yabasebenzi, kwaye ihlangabezana neemfuno ezikhoyo zeCMC. Iimfuno ze-automation yemveliso yeshishini.

3. Amathuba okufaka isicelo

Kwiminyaka yakutshanje, ishishini lelizwe lam le-CMC liyaguquka ukusuka kwimveliso enzima ukuya kwimveliso ezenzekelayo, ukuphuhlisa uphando lwezixhobo ezitsha kunye nophuhliso, kwaye ngokuqhubekayo nokuphucula inkqubo ngokudibanisa neempawu zezixhobo, ukuze kuqatshelwe imveliso yeCMC ngexabiso eliphantsi. kwaye ulungiselele iimveliso ezikumgangatho ophezulu. Injongo efanayo yamashishini emveliso yeCMC. Isiphakamisi somoya sohlobo lwe-coulter siyahlangabezana kakhulu nale mfuneko kwaye lukhetho olufanelekileyo lwezixhobo zokuvelisa zeCMC.
