I-Pulp Concentration Measurement
Uxinzelelo lwe-pulp kwisifuba somatshini lufikelela kwi-2.5-3.5% ngokubanzi. Amanzi afunekayo ukuhlambulula i-pulp kwi-concentration ephantsi ye-fibers ehlakazekileyo kakuhle kunye nokususwa kokungcola.
Kubaoomatshini abanedrinier, i-pulp concentration ingena kwi-mesh yi-0.3-1.0% ngokuqhelekileyo ngokweempawu ze-pulp, izixhobo zezixhobo, kunye nomgangatho wephepha. Kweli nqanaba, inqanaba le-dilution lihambelana nokugxininiswa kwe-pulp efunekayo kwi-mesh, oku kuthetha ukuba ugxininiso olufanayo lusetyenziselwa ukuhlanjululwa, ukuhluzwa, kunye nokwenza kwi-mesh.
I-pulp concentration kwi-mesh iphantsi kwi-0.1-0.3% kuphela kumatshini we-cylinder. Isantya sokuhamba ngokucocwa kunye nokuhluzwa siphezulu kuneemfuno kunye ne-pulp yoxinaniso oluphantsi. Ngaphaya koko, izixhobo ezingaphezulu zokucoca kunye nokucoca ziyafuneka ukuze kusetyenzwe i-pulp yoxinaniso oluphantsi, efuna imali eninzi, indawo enkulu, imibhobho entsonkothileyo, kunye nokusetyenziswa okuphezulu kwamandla.
Oomatshini be-cylinder bahlala bethatha ainkqubo yokuhlanjululwa kwamanqanaba amabini,apho ugxininiso lwehliselwa kwi-0.5 ~ 0.6% okokuqala ukuhlanjululwa kwangaphambili kunye nokucoca; emva koko ithotywe ukuya kugxininiso olujoliswe phambili phambi kokungena kumnatha kwibhokisi yokuzinzisa.
I-Pulp dilution isebenzisa amanzi amhlophe ngomnatha oqhelekileyo wogcino lwamanzi kunye nokubuyiselwa kwemicu emihle, izihluzi kunye neekhemikhali kumanzi amhlophe. Ukubuyiswa kwamanzi amhlophe kuyinzuzo kugcino lwamandla koomatshini abafuna ukufudumeza ipulp.
Imiba ephambili echaphazela ukuGxininiswa kwePulp eDiluted
Ukwahluka kwiPulp Concentration yokungena kwiBhokisi yoLawulo
Ukuguquguquka kokuhambelana ukusuka ekubetheni okanye utshintsho kwinkqubo ephukileyo kunokubangela ukuhluka koxinzelelo lwe-pulp. Ukujikeleza kakubi kwisifuba somatshini kunokukhokelela ekugxininiseni kwe-pulp engahambelaniyo kwiindawo ezahlukeneyo, kubangela ukungazinzi okuqhubekayo.
Ukubuyela ngasemva kokwalas kwiUkuhlanjululwa kunyeukuhluzwa
Ukwaliwa kokucocwa kunye nokuhluzwa ngokuqhelekileyo kuphinda kufakwe kwisixokelelwano ngamanzi okuhlamba. Ukwahluka kumthamo kunye nokugxininiswa koku kugatywa kuxhomekeke ekusebenzeni kokucoca kunye nezixhobo zokucoca kunye namanqanaba olwelo kwiimpompo zokungena.
Olu tshintsho luvelisa iimpembelelo kugxininiso lwamanzi amhlophe asetyenziselwa ukuhlanjululwa kwaye, ngokulandelelana, ugxininiso lwepulp lokugqibela. Imiba efanayo inokwenzeka kwiinkqubo zokubuya kweetanki zomatshini we-cylinder ophuphumayo.
Iiyantlukwano ekugxininiseni kwe-pulp edibeneyo inokuchaphazela zombini ukusebenza komatshini wephepha kunye nomgangatho wephepha lokugqibela. Ke ngoko, kubalulekile ukubeka iliso ngokusondeleyo ukugxilwa kwepulp ngeukungqinelana imitha pulpyenziwe nguLonnmeterngexesha lokuvelisa kunye nokulungelelanisa ukungena kwibhokisi yokulawula ukugcina ukugxininiswa okuzinzile. Oomatshini bephepha bale mihla bahlala besebenzisa izixhobo ezizisebenzelayo ukuze:
- Lungisa ngokuzenzekelayo iukugxininiswa kwe-pulpukungena kwibhokisi elawulayo.
- Lungisa ukungena ngokusekelwe kwiinguqu kwisiseko sephepha ubunzima kunyeheadbox pulp concentration.
Oku kuqinisekisa ukuzinza kwe-pulp concentration.
Izibonelelo zoLungiso lweNxibelelwano kwiPulp eDiluted
Ulawulo lokugxininiswa kweenzuzo ze-pulp ezixutywe kuzo zombini ukusebenza ngokufanelekileyo komatshini wephepha kunye nokugcinwa komgangatho wephepha.
Eyoomatshini beSilinda
Xa i-pulp inezinga eliphantsi lokubetha kwaye i-dewaters ngokukhawuleza, amanqanaba amanzi angaphakathi nangaphandle kwinqanaba le-mesh liyancitshiswa, linciphisa ukudibanisa kwephepha lephepha kwi-mesh. Oku kwandisa umphumo wogxininiso, kunciphisa ukuphuphuma, kwaye kwandisa ukwahlukana kwesantya phakathi kwe-pulp kunye ne-mesh, ekhokelela ekubunjweni kwephepha elingalinganiyo.
Ukujongana noku, ukusetyenziswa kwamanzi amhlophe kunyuswa ukuthoba i-pulp concentration, ukwandisa izinga lokuhamba kwi-mesh. Oku kuphakamisa umahluko wenqanaba lamanzi, kwandisa ukuphuphuma, kunciphisa iziphumo zokuxininisa, kunye nokunciphisa ukwahlukana kwesantya, ngaloo ndlela kuphuculwe ukufana kwamaphepha.
Ngooomatshini beFourdrinier
Iidigri eziphezulu zokubetha zenza ukukhutshwa kwamanzi kube nzima, ukwandisa umgca wamanzi, ukwandisa umswakama kwiphepha elimanzi, kwaye kukhokelela ekufakeni okanye ukutyumza ngexesha loxinzelelo. Ukuxinana kwephepha kuwo wonke umatshini kunciphisa, kwaye ukushwabana ngexesha lokomisa kuyanda, kubangela iziphene ezinje ngokugotywa kunye nemibimbi.
Ukoyisa le miceli mngeni, ukugxininiswa kwe-pulp edibeneyo kunokongezwa ngokunciphisa ukusetyenziswa kwamanzi amhlophe, ukunciphisa imiba yokukhupha amanzi.
Ngokwahlukileyo, ukuba iqondo lokubetha liphantsi, iifibers zivame ukudada, kwaye ukukhutshwa kwamanzi kwenzeka ngokukhawuleza kwi-mesh, echaphazela ukufana kwephepha. Kule meko, ukonyusa ukusetyenziswa kwamanzi amhlophe ukuthoba ingxinano ye-pulp edilulisiweyo kunokunciphisa i-flocculation kunye nokuphucula ukufana.
Ukuqukumbela
I-Dilution ngumsebenzi obalulekileyo ekwenzeni iphepha. Kwimveliso, kubalulekile ukuba:
- Jonga ngokusondeleyo kwaye ulawule ngokungqongqo utshintsho kwi-dilutedukugxininiswa kwe-pulpukuqinisekisa ukusebenza okuzinzileyo.
- Nika ingqalelo utshintsho kumgangatho wemveliso kunye neemeko zokusebenzakwaye, xa kuyimfuneko, hlengahlengisa ugxininiso lwe-pulp njengesixhobo sokoyisa ubunzima obufana nobo bukhankanywe ngasentla.
Ngokulawula ngempumelelo i-pulp dilution, imveliso ezinzileyo, iphepha elikumgangatho ophezulu, kunye nokusebenza kakuhle kunokufezekiswa.
