Mumaitiro echinyakare ekugadzira cellulose ether nenzira yekunyungudutsa, crude product ye carboxymethyl cellulose (inozonzi CMC) inowanikwa ne etherification reaction inogona kuwanikwa nekunatsa maitiro senge neutralization washing, kuomesa kurapa, kupwanya uye granulation, nezvimwe. Chete chikamu che ethanol chiri muCMC isina kuchena chiri pamusoro chinodzoserwa ne distillation pamwe nemunyu we sodium panguva yekusagadzikana uye kugeza maitiro, uye chimwe chikamu che ethanol chinochengetwa muCMC isina kuchena, yakaomeswa, yakapurwa, granulated uye yakaiswa mukati meCMC yapera. . recycle. Mumakore achangopfuura, mutengo we organic solvents wakaramba uchikwira. Kana ethanol isingagone kudzokororwa, haingokonzeresa kutambisa zviwanikwa, asi zvakare kuwedzera mutengo wekugadzira weCMC, izvo zvinokanganisa purofiti yechigadzirwa uye kuderedza kukwikwidza kwechigadzirwa. Muchirevo chechinyorwa chino, vamwe vagadziri veCMC vanovandudza kuyerera kwemaitiro uye vanoshandisa rake vacuum dryer mukuita kwekutengesa uye kuomesa, asi rake vacuum dryer rinogona kungoshandiswa nekupindirana, uye kusimba kwebasa kwakakwira, izvo zvisingakwanise kuzadzisa zvinodiwa iripo CMC kugadzirwa. otomatiki zvinodiwa. Chikwata cheR&D cheZhejiang Provincial Research Institute yeChemical Indasitiri yakagadzira coulter-mhando yemhepo stripper yeCMC dealcoholization uye kuomesa maitiro, kuitira kuti ethanol ikurumidze uye inyudzwe zvizere kubva muCMC crude chigadzirwa uye idzokororwe kuti ishandiswe, uye panguva imwecheteyo. nguva inopedzisa kushanda kweCMC yekuomesa maitiro. Uye inogona kuona kuenderera mberi kwekushanda kweCMC kugadzirwa, uye ndiyo yakanaka yekutsiva midziyo ye rake vacuum dryer muCMC kugadzirwa maitiro.

1. Dhizaini chirongwa che coulter air lifter ye cellulose ether indasitiri

1.1 Mamiriro ezvimiro zvecolter air lifter

Iyo coulter type air lifter inonyanya kuumbwa neyekutapurirana michina, yakachinjika yekudziya bhachi muviri, gejo mugove, rinobhururuka banga reboka, epoust tank, yekuburitsa michina uye chiutsi nozzle uye zvimwe zvakakosha zvinhu. Iyi modhi inogona kuve yakashongedzerwa nemudziyo wekudyisa pane inopinza uye yekuburitsa mudziyo pane yekubuda. Iyo volatilized ethanol inoburitswa kuburikidza ne exhaust tank uye inodzokororwa kuti ishandiswe, nekudaro kuona kuenderera kwekushanda kweCMC kugadzirwa.

1.2 Kushanda musimboti wecolter air lifter

Pasi pekuita kwe coulter, iyo CMC crude product turbulences pamwe nemukati memadziro ecylinder mu circumferential uye radial nzira kune rumwe rutivi, uye inokandwa pamwe neyakajairika nzira yemativi maviri ecolter kune rumwe rutivi; apo chinhu chinobvongodza chinoyerera chichiyerera nebanga rinobhururuka, Yakaparadzirwawo zvakasimba nebanga rinotenderera rinobhururuka. Pasi pechiito chakabatanidzwa chemakororo uye mapanga anobhururuka, CMC crude product inokurumidza kutenderedzwa uye kupwanywa kuti iwedzere nzvimbo iyo ethanol inogona kuputika; panguva imwecheteyo, zvinhu zviri mucylinder zvinopiswa nejacket steam uye mhepo inopfuudzwa mucylinder kuti inyatsopisa zvinhu Pasi pekushanda kweviri kwe ethanol, kushanda kwemhepo uye kushanda kwe ethanol kunovandudzwa zvikuru, uye ethanol inoparadzaniswa nekukurumidza uye zvakakwana. Panguva imwechete yedealcoholization, mhepo iri mujasi inopisa zvinhu zviri muhumburumbira uye inopedzisa kuomesa kweCMC. pashure. Iyo CMC mushure mekuita dhiricoholization uye kuomeswa inogona kupinda mune inotevera yekupwanya, granulation uye chigadzirwa kurongedza maitiro mushure mekuburitswa kubva pakuburitsa michina.

1.3 Yakakosha coulter chimiro uye kuronga

Kuburikidza nekutsvagisa pamusoro pehunhu hweCMC, vaongorori vakasarudza kushandisa colter musanganiswa wakagadzirwa mukutanga nhanho seyokutanga modhi, uye akavandudza chimiro chechimiro uye coulter kurongeka kwecolter kakawanda. Chinhambwe chiri pakati pemakorokoto maviri akatarisana mune inotenderera nzira Iyo inosanganisirwa kona ndeyeα, α iri 30-180 madhigirii, akarongedzerwa mune inotenderera pane huru shaft, uye kumashure kweiyo coulter ine arc concave kuti iwedzere kupfapfaidza simba rezvinhu pamwe neyakajairwa nzira yemativi maviri e coulter, kuitira kuti zvinhu. inokandwa uye yakapwanyika zvakanyanya sezvinobvira kuwedzera nzvimbo iyo ethanol inogona kuputika, kuitira kuti iyo ethanol inotorwa muCMC crude product inokwana.

1.4 Dhizaini yehumburumbira chikamu chechiyero

Kuti uone kuenderera mberi kwekushanda kweanosimudza mhepo, kureba kwebhodhoro kwakareba kupfuura iyo yemusanganisi mukuru. Kuburikidza nekuvandudzwa kwakati wandei mumagadzirirwo ereshiyo yehurefu kusvika kudhayamita yemuviri wakarerutswa, iyo yakakwana kureba-kusvika-dhayamita reshiyo yemuviri wakarerutswa yakazowanikwa, kuitira kuti ethanol igone kunyungudutswa uye kupihwa kubva mutangi rekuburitsa mu. nguva, uye kushanda kweCMC kuomesa maitiro kunogona kupedzwa panguva imwe chete. Iyo CMC mushure mekuita dhiricoholization uye kuomesa yakananga inopinda maitiro ekupwanya, granulation uye chigadzirwa kurongedza, ichiziva iyo yakazara-mutsara otomatiki yeCMC kugadzirwa.

1.5 Dhizaini yeakakosha nozzles

Pazasi pehumbururu pane muromo unokosha wekusvira. Iyo muromo yakashongedzerwa nechitubu. Kana chiutsi chapinda, mutsauko wepressure unoita kuti chivharo chemhino chivhurike. Kana chiutsi chisiri kuyerera, chivharo chemhino chinovhara muromo pasi pekumanikidzana kwechitubu kudzivirira CMC isina kuchena kubva pakuburitswa. Ethanol inodonha kubva mumuromo.

2. Zvimiro zvecolter air lifter

Iyo coulter-type air lifter ine chimiro chakareruka uye chine musoro, inogona kubvisa ethanol nekukurumidza uye zvizere, uye inokwanisa kuona kuenderera kwekushanda kweCMC dealcoholization drying process, uye yakachengeteka uye iri nyore kuisa, kushanda nekuchengetedza. Vamwe vatengi vakapa mhinduro mushure mekuishandisa. Kushandisa muchina uyu hakungove neakanyanya kudzoreredza mwero wekutora ethanol uye kushomeka kwesimba rekushandisa, asi zvakare kunatsiridza mhando yechigadzirwa, inoderedza mutengo wekugadzira, uye inochengetedza zviwanikwa zve ethanol. Panguva imwecheteyo, inovandudza zvakanyanya mamiriro ekushanda uye kubudirira kwevashandi, uye inosangana nezvinodiwa neCMC zviripo. Maindasitiri ekugadzira otomatiki zvinodiwa.

3. Tarisiro yekushandisa

Mumakore achangopfuura, indasitiri yeCMC yenyika yangu iri kushanduka kubva mukugadzirwa kwakasimba kuenda kukugadzira otomatiki, ichishingairira kugadzira mitsva yekutsvaga nekusimudzira, uye ichienderera mberi nekuvandudza maitiro pamwe chete nehunhu hwemidziyo, kuitira kuti ikwanise kugadzirwa kweCMC nemutengo wakaderera. uye gadzira zvigadzirwa zvemhando yepamusoro. Chinangwa chakafanana cheCMC mabhizinesi ekugadzira. Iyo coulter type air lifter inosangana zvakanyanya nezvinodiwa izvi uye isarudzo yakanaka yeCMC yekugadzira maturusi emidziyo.
