Ukulinganisa Uxinzelelo lwePulp
Uxinzelelo lwe-pulp esifubeni somatshini lufikelela kwi-2.5–3.5% ngokubanzi. Amanzi ayadingeka ukuze kuncitshiswe i-pulp ibe luxinzelelo oluphantsi ukuze kususwe iifayibha ezisasazekileyo kakuhle kwaye kususwe ukungcola.
Ngokubaoomatshini be-fourdrinier, uxinaniso lwepulp olungena kwi-mesh luyi-0.3–1.0% ngokwesiqhelo ngokweempawu zepulp, iimpawu zezixhobo, kunye nomgangatho wephepha. Kweli nqanaba, inqanaba lokuxuba lihambelana noxinaniso lwepulp olufunekayo kwi-mesh, oko kuthetha ukuba uxinaniso olufanayo lusetyenziselwa ukucoca, ukucoca, kunye nokwenza kwi-mesh.
Uxinzelelo lwe-pulp kwi-mesh luphantsi ukuya kwi-0.1–0.3% kuphela kwiimashini zesilinda. Izinga lokuhamba kokucoca kunye nokucoca liphezulu kuneemfuno ze-pulp enoxinzelelo oluphantsi. Ngaphezu koko, kufuneka izixhobo zokucoca kunye nokucoca ezingaphezulu ukuze kucutshungulwe i-pulp enoxinzelelo oluphantsi, nto leyo efuna imali eninzi, indawo enkulu, imibhobho enzima ngakumbi, kunye nokusetyenziswa kwamandla aphezulu.
Oomatshini besilinda badla ngokusebenzisainkqubo yokuxuba enamanqanaba amabini,apho uxinzelelo lwehliswa luye kwi-0.5 ~ 0.6% kuqala ukuze kucocwe kwaye kuhluzwe kwangaphambili; emva koko kwehliswa ukuya kuxinzelelo olujoliswe kulo ngakumbi ngaphambi kokuba lufakwe kwi-mesh kwibhokisi yokuzinzisa.
Ukuxutywa kwepulp kusebenzisa amanzi amhlophe nge-mesh njengesiqhelo sokugcina amanzi kunye nokubuyisa imicu emincinci, izizalisi, kunye neekhemikhali ezivela kumanzi amhlophe. Ukubuyiswa kwamanzi amhlophe kuluncedo ekugcineni amandla kwiimashini ezifuna ukufudumeza ipulp.
Izinto Eziphambili Ezichaphazela Ukuxinana Kweempulphu Ezixutyiweyo
Utshintsho kwiPulp Concentration Ukungena kwiBhokisi eLawulayo
Ukuguquguquka kokungaguquguquki kokubetha okanye utshintsho kwinkqubo ephukileyo kunokubangela utshintsho kuxinzelelo lwepulp. Ukujikeleza kwegazi okungalunganga kwizifuba zomatshini kunokukhokelela kuxinzelelo lwepulp olungaguquguqukiyo kwiindawo ezahlukeneyo, okubangela ukungazinzi okungakumbi.
Ukubuyela umva kokugatywas ngaphakathiUkuhlanjululwa kunyeukuhluza
Ukulahlwa okuvela ekuhlanjululweni nasekuhluzweni kudla ngokubuyiselwa kwinkqubo ngamanzi axutyiweyo. Utshintsho kumthamo kunye noxinzelelo lwale nkunkuma luxhomekeke ekusebenzeni kwezixhobo zokucoca kunye nokucoca kunye namanqanaba olwelo kwiindawo zokungena zepompo.
Olu tshintsho lubangela impembelelo kuxinzelelo lwamanzi amhlophe olusetyenziselwa ukunyibilikisa, kwaye, kuxinzelelo lokugqibela lwepulp. Iingxaki ezifanayo zinokwenzeka kwiinkqubo zokubuyisela iitanki zoomatshini besilinda.
Utshintsho kuxinzelelo lwepulp oluxutyiweyo lunokuchaphazela zombini ukusebenza komatshini wephepha kunye nomgangatho wokugqibela wephepha. Ke ngoko, kubalulekile ukujonga ngokusondeleyo uxinzelelo lwepulp kunyeipulp yemitha yokuvumelanayenziwe nguILonnmeterngexesha lokuvelisa kwaye ulungelelanise ukungena kwemveliso kwibhokisi elawulayo ukuze kugcinwe uxinano oluzinzileyo. Oomatshini bephepha banamhlanje badla ngokusebenzisa izixhobo ezizenzekelayo ukuze:
- Lungisa ngokuzenzekelayouxinaniso lwepulpukungena kwibhokisi yokulawula.
- Lungisa ukungena kwemali ngokusekelwe kutshintsho kubunzima bephepha kunyeuxinaniso lwepulp yebhokisi yentloko.
Oku kuqinisekisa ukuba i-pulp ihlala iqinile.
Iingenelo zoLungiso loXinzelelo kwiDiluted Pulp
Ulawulo lokugxila kwe-pulp exutyiweyo lunceda ekusebenzeni kakuhle komatshini wephepha kunye nokugcinwa komgangatho wephepha.
Kwiimashini zesilinda
Xa i-pulp ineqondo eliphantsi lokubetha kwaye ikhupha amanzi ngokukhawuleza, amanqanaba amanzi angaphakathi nangaphandle kwicandelo le-mesh ayancitshiswa, nto leyo ebangela ukuba umaleko wephepha ungabi buthathaka kwi-mesh. Oku kwandisa isiphumo soxinzelelo, kunciphisa ukugcwala, kwaye kwandisa umahluko wesantya phakathi kwe-pulp kunye ne-mesh, nto leyo ekhokelela ekwakhiweni kwephepha okungalinganiyo.
Ukujongana nale meko, ukusetyenziswa kwamanzi amhlophe kuyandiswa ukuze kuncitshiswe uxinano lwepulp, kwandisa izinga lokuhamba kwamanzi ukuya kwi-mesh. Oku kuphakamisa umahluko wamanzi, kwandisa ukugcwala kwamanzi, kunciphisa iziphumo zoxinano, kwaye kunciphisa umahluko wesantya, ngaloo ndlela kuphucula ukufana kwamaphepha.
Kwiimashini zeFourdrinier
Amaqondo aphezulu okubetha enza kube nzima ukufunxa amanzi, andise umngxuma wamanzi, andise ukufuma kwiphepha elimanzi, kwaye akhokelela ekufakweni okanye ekutyumzeni ngexesha lokucinezela. Uxinzelelo lwamaphepha kumatshini luyancipha, kwaye ukushwabana ngexesha lokomisa kuyanda, okubangela iziphene ezifana nokugoba kunye nemibimbi.
Ukuze koyiswe le mingeni, uxinaniso lwepulp oluxutyiweyo lunokwandiswa ngokunciphisa ukusetyenziswa kwamanzi amhlophe, nto leyo enciphisa iingxaki zokukhupha amanzi.
Ngokwahlukileyo koko, ukuba iqondo lokubetha liphantsi, imicu idla ngokutyibilika, kwaye ukuphuma kwamanzi kwenzeka ngokukhawuleza kwi-mesh, nto leyo echaphazela ukufana kwephepha. Kwimeko enjalo, ukusetyenziswa kwamanzi amhlophe okwandisa ukunciphisa uxinano lwe-pulp exutyiweyo kunokunciphisa ukutyibilika kwaye kuphucule ukufana.
Isiphelo
Ukuxuba izinto yindlela ebalulekileyo yokwenza iphepha. Kwimveliso, kubalulekile:
- Lawula ngokusondeleyo kwaye ulawule ngokungqongqo utshintsho oluphuculweyouxinaniso lwepulpukuqinisekisa ukusebenza okuzinzileyo.
- Nika ingqalelo kutshintsho olukwizinga lemveliso kunye neemeko zokusebenzakwaye, xa kuyimfuneko, lungisa uxinaniso lwepulp njengesixhobo sokunqoba iingxaki ezifana nezo zikhankanyiweyo apha ngasentla.
Ngokulawula ngokufanelekileyo ukuxutywa kwepulp, imveliso ezinzileyo, iphepha elisemgangathweni ophezulu, kunye nokusebenza ngokugqibeleleyo kunokufezekiswa.
