Coulter Air Lifter kwa Makampani a Cellulose Ether

Mpweya wamtundu wa coulter womwe umagwira ntchito mosalekeza umapangidwa, womwe umagwiritsidwa ntchito makamaka ngati zida zowumitsa za dealcoholization popanga kupanga cellulose ether ndi njira yosungunulira, kuti azindikire bwino komanso mosalekeza ntchito yowumitsa ya dealcoholization, ndipo pamapeto pake amazindikira. cholinga cha kupanga CMC. Kugwira ntchito mosalekeza.

Mawu ofunikira: carboxymethyl cellulose ether (CMC mwachidule); ntchito mosalekeza; chonyamulira mpweya

Pachikhalidwe kupanga mapadi efa ndi njira zosungunulira, mankhwala osakhwima a carboxymethyl mapadi (pano amatchedwa CMC) akamagwira etherification anachita angapezeke mwa kuyenga njira monga neutralization kutsuka, kuyanika mankhwala, kuphwanya ndi granulation, etc. Gawo lokha la ethanol zili pamwamba pa CMC yaiwisi ndi anachira ndi distillation pamodzi ndi mchere sodium pa neutralization ndi ndondomeko kutsuka, ndi mbali ina ya Mowa amasungidwa mu CMC yaiwisi, zouma, pulverized, granulated ndi mmatumba mu anamaliza CMC. . konzanso. M'zaka zaposachedwapa, mtengo wa zosungunulira organic anapitiriza kukwera. Ngati Mowa sangathe kubwezerezedwanso, sizidzangowononga chuma, komanso kuonjezera mtengo wopangira CMC, zomwe zingakhudze phindu lazinthu ndikuchepetsa kupikisana kwazinthu. M'nkhaniyi, ena opanga CMC amawongolera kayendetsedwe ka kayendetsedwe kake ndikugwiritsa ntchito chowumitsira chowumitsira panthawi ya dealcoholization ndi kuyanika, koma chowumitsira chowumitsira chitha kugwiritsidwa ntchito pang'onopang'ono, ndipo kulimbika kwa ntchito ndikwambiri, zomwe sizingakwaniritse zofunikira za Kupanga kwa CMC komwe kulipo. zofunika zokha. Gulu la R&D la Zhejiang Provincial Research Institute of Chemical Viwanda lapanga chopukusira mpweya wamtundu wa coulter kwa CMC dealcoholization ndi kuyanika njira, kuti Mowa ukhale wowongoka mwachangu komanso wowongoka kuchokera ku CMC wakuda ndikusinthidwanso kuti ugwiritse ntchito, komanso nthawi yomweyo. nthawi kumaliza ntchito ya CMC kuyanika ndondomeko. Ndipo imatha kuzindikira kugwira ntchito kosalekeza kwa kupanga CMC, ndipo ndi zida zosinthira zowumitsa vacuum popanga CMC.

1. Chiwembu chopanga chonyamulira mpweya wa coulter kwamakampani a cellulose ether

1.1 Mawonekedwe a coulter air lifter

Chonyamulira mpweya chamtundu wa coulter chimapangidwa makamaka ndi makina otumizira, thupi la jekete yopingasa, gawo lolimira, gulu la mpeni wowuluka, thanki yotulutsa mpweya, makina otulutsa ndi mpweya wa nthunzi ndi zinthu zina zazikulu. Chitsanzochi chikhoza kukhala ndi chipangizo chodyera pa malo olowera ndi chipangizo chotulutsira panja. The volatilized Mowa ndi kutulutsidwa kudzera mu thanki utsi ndi zobwezerezedwanso ntchito, potero kuzindikira mosalekeza ntchito ya CMC kupanga.

1.2 Mfundo yogwirira ntchito yonyamula mpweya

Pansi pa zochita za coulter, ndi CMC yaiwisi mankhwala turbulences pamodzi mkati khoma la yamphamvu mu circumferential ndi zozungulira malangizo pa dzanja limodzi, ndi kuponyedwa pamodzi malangizo yachibadwa mbali ziwiri za coulter mbali inayo; pamene zida zogwedeza zimayenda kupyolera mu mpeni wowuluka, Zinamwazikananso mwamphamvu ndi mpeni wowuluka wothamanga kwambiri. Pansi pa machitidwe ophatikizana a ma coulters ndi mipeni yowuluka, chinthu cha CMC chopanda pake chimasinthidwa mwachangu ndikuphwanyidwa kuti chiwonjezeke pamalo pomwe Mowa ukhoza kutenthedwa; nthawi yomweyo, zinthu zomwe zili mu silinda zimatenthedwa ndi nthunzi ya jekete ndipo nthunzi imadutsa mu silinda kuti itenthetsere zinthuzo Pansi pa ntchito iwiri ya ethanol, mphamvu ya volatilization ndi zotsatira za ethanol zimakhala bwino kwambiri, ndipo Mowa umalekanitsidwa mwamsanga ndi bwinobwino. Pa nthawi yomweyi ya dealcoholization, nthunzi mu jekete imatenthetsa zinthu mu silinda ndikumaliza kuyanika kwa CMC. pambuyo pake. The CMC pambuyo dealcoholization ndi kuyanika akhoza kulowa wotsatira kuphwanya, granulation ndi mankhwala ma CD ndondomeko pambuyo kumasulidwa kumakina kumaliseche.

1.3 Mapangidwe apadera a coulter ndi makonzedwe

Kupyolera mu kafukufuku wa makhalidwe a CMC, ofufuzawo anasankha kugwiritsa ntchito chosakaniza cha coulter chomwe chinapangidwa koyambirira ngati chitsanzo choyambirira, ndikuwongolera mawonekedwe ndi makonzedwe a coulter nthawi zambiri. Mtunda pakati pa ma coulters awiri oyandikana munjira yozungulira Mbali yophatikizidwa ndiα, α ndi madigiri a 30-180, okonzedwa mozungulira pamtunda waukulu, ndipo kumapeto kwa khola kumakhala ndi arc concave kuti apititse patsogolo mphamvu yowonongeka ya zinthuzo motsatira njira yachibadwa ya mbali ziwiri za coulter, kuti zinthuzo zitheke. amaponyedwa ndi kuphwanyidwa momwe angathere kuti awonjezere malo omwe Mowa amatha kugwedezeka, kotero kuti m'zigawo za ethanol mu CMC yakuda ndi yokwanira.

1.4 Mapangidwe a chiŵerengero cha silinda

Kuti muzindikire kugwira ntchito kosalekeza kwa chonyamulira mpweya, kutalika kwa mbiya ndi yayitali kuposa ya osakaniza ambiri. Kupyolera mu kusintha kangapo mu kamangidwe ka chiŵerengero cha kutalika kwa m'mimba mwake wa thupi chosavuta, ndi momwe akadakwanitsira kutalika ndi m'mimba mwake chiŵerengero cha thupi chosavuta anapezedwa, kotero kuti Mowa akhoza mokwanira volatilized ndi kuperekedwa kwa thanki utsi mu nthawi, ndi ntchito ya CMC kuyanika ndondomeko akhoza kutha nthawi yomweyo. The CMC pambuyo dealcoholization ndi kuyanika mwachindunji akulowa ndondomeko kuphwanya, granulation ndi ma CD mankhwala, kuzindikira zonse mzere zochita zokha za CMC kupanga.

1.5 Mapangidwe a ma nozzles apadera

Pansi pa silinda pali phokoso lapadera lopangira nthunzi. Mphunoyi ili ndi kasupe. Pamene nthunzi ilowa, kusiyana kwa kuthamanga kumapangitsa kuti chivundikiro cha nozzle chitseguke. Pamene nthunzi sikuyenda, chivundikiro cha nozzle chimatseka mphuno pansi pa kukangana kwa kasupe kuteteza CMC yakuda kuti itulutsidwe. Ethanol imatuluka mumphuno.

2. Makhalidwe a colter air lifter

Mpweya wamtundu wa coulter uli ndi mawonekedwe osavuta komanso omveka, amatha kutulutsa Mowa mwamsanga komanso mokwanira, ndipo amatha kuzindikira ntchito yosalekeza ya CMC dealcoholization kuyanika ndondomeko, ndipo ndi yotetezeka komanso yosavuta kukhazikitsa, kugwira ntchito ndi kusamalira. Makasitomala ena apereka ndemanga atagwiritsa ntchito. Kugwiritsa ntchito makinawa osati ndi mkulu kuchira mlingo wa Mowa m'zigawo ndi otsika mphamvu mowa, komanso bwino mankhwala khalidwe, amachepetsa mtengo kupanga, ndipo amapulumutsa Mowa chuma. Nthawi yomweyo, imathandizira kwambiri magwiridwe antchito komanso zokolola zantchito, ndikukwaniritsa zofunikira za CMC. Zofunikira zopangira makina opanga mafakitale.

3. Zoyembekeza zogwiritsa ntchito

M'zaka zaposachedwa, makampani a CMC akudziko langa akusintha kuchoka pakupanga kwantchito mpaka kupanga makina, kupanga kafukufuku wa zida zatsopano ndi chitukuko, ndikuwongolera mosalekeza njirayo kuphatikiza mawonekedwe a zida, kuti azindikire kupanga CMC pamtengo wotsika. ndikukonzekera mankhwala apamwamba. Cholinga chimodzi chamakampani opanga CMC. Chonyamula mpweya chamtundu wa coulter chimakwaniritsa izi ndipo ndi chisankho chabwino pazida zopangira zida za CMC.
