A4 luam ntawv tshuab uas qhov tseeb yog daim ntawv ua kab kuj tseem muaj cov seem sib txawv;
1-Txoj kev ntws mus rau ntu uas kho qhov ntws mus rau cov khoom sib xyaw ua ke los ua daim ntawv nrog lub hauv paus hnyav. Qhov hnyav ntawm daim ntawv yog qhov hnyav ntawm ib square meter hauv grams. Cov dej ntws ntawm cov slurry uas yog diluted yuav raug ntxuav, tshuaj xyuas hauv cov ntxaij vab tshaus thiab xa mus rau lub taub hau lub thawv.
2- Lub taub hau lub thawv nthuav tawm cov dej ntws ntawm cov ntaub ntawv slurry heev uniformly hla lub dav ntawm daim ntawv tshuab hlau. Kev ua tau zoo ntawm lub taub hau lub thawv yog txiav txim siab hauv kev txhim kho qhov zoo ntawm cov khoom kawg.
3- Hlau ntu; Pulp slurry yog sib npaug ntawm cov xaim txav thiab cov xaim txav mus rau qhov kawg ntawm cov xaim, yuav luag 99% ntawm cov dej ntws tawm thiab lub vev xaib ntub dej nrog qhov qhuav ntawm li 20-21% yog pauv mus rau ntu xovxwm. ntxiv dewatering.
4- Xovxwm Tshooj; Cov xovxwm dewaters lub vev xaib ntxiv kom ncav cuag qhov qhuav ntawm 44-45%. Cov txheej txheem dewatering hauv txhua yam tsis siv lub zog thermal. Cov xovxwm feem ntau siv 2-3 nips nyob ntawm cov tshuab xovxwm thiab kev teeb tsa.
5-Dryer Section: Lub tshuab ziab khaub ncaws ntawm kev sau ntawv, luam ntawv thiab luam ntawv tshuab yog tsim nyob rau hauv ob ntu, ib lub tshuab ziab khaub ncaws thiab tom qab tshuab ziab khaub ncaws txhua tus siv ntau lub tshuab ziab khaub ncaws uas siv saturated steam li cua sov nruab nrab. Lub vev xaib ntub dej yog qhuav rau 92% dryness thiab lub vev xaib qhuav no yuav yog qhov loj me ntawm 2-3 grams / square meter / sab ntawm cov hmoov txhuv nplej siab uas tau npaj hauv cov kua nplaum ua noj. Daim ntawv web tom qab sizing yuav muaj li 30-35% dej. Lub vev xaib ntub dej no yuav ua kom qhuav ntxiv tom qab lub tshuab ziab khaub ncaws rau 93% dryness haum rau kev siv kawg.
6- Daim Ntawv Teev Npe: Daim ntawv tawm tom qab tshuab ziab khaub ncaws tsis haum rau kev luam ntawv, sau ntawv thiab luam tawm vim tias daim ntawv saum npoo tsis zoo txaus.
7- Kev sib tw; Thaum kawg ntawm lub tshuab ntawv, lub web qhuav ntawm daim ntawv raug mob nyob ib ncig ntawm ib tug hnyav hlau yob mus txog 2.8 meter inch. Daim ntawv ntawm cov yob no yuav muaj txog 20 tons. Qhov no jumbo ntawv yob winding tshuab yog hu ua pope reeler.
8 - Rov qab; Qhov dav ntawm daim ntawv ntawm daim ntawv yob yog yuav luag qhov dav ntawm daim ntawv tshuab hlau. Daim ntawv yob no yuav tsum tau txiav lengthwise thiab dav raws li kev txiav txim los ntawm kev siv kawg. Qhov no yog lub luag haujlwm ntawm lub rewinder los faib cov jumbo yob nyob rau hauv nqaim yob.
