Cov zis txhua xyoo muab qhov xav tau nruab nrab txhua hnub, tab sis qhov loj me txhais tau tias kuaj xyuas qhov siab tshaj plaws thiab cov teev cov kab khiav tiag tiag. Cov piv txwv hauv qab no ua haujlwm los ntawm cov lej suav los qhia tus nqi xav tau.
Koj suav peb qhov twg?
Kev suav cov peev xwm xav tau ib lub hauv paus rau kev sib piv cov zis. Cov khoom siv raw yog ntsuas hauv tonnes ib teev, cov khoom tiav hauv tonnes ib hnub twg, thiab ntim cov khoom ntim rau hauv hnab lossis nruas ib teev. Siv cov yield, concentration factor thiab pob hom los hloov ntawm cov kev ntsuas no. Tib qhov ntau ntawm cov txiv hmab txiv ntoo tsim cov khoom sib txawv ntawm cov kua txiv hmab txiv ntoo thiab 70 Brix mloog zoo, yog li thawj zaug paub meej tias cov khoom twg cov duab xa mus.

Ntev npaum li cas txoj kab tuaj yeem khiav?
Qhov ntsuas lub npe ntawm qhov ntsuas qhov ua haujlwm tas mus li. Txhawm rau nrhiav cov sij hawm siv tau, txiav tawm lub sijhawm los ntawm tag nrho cov sijhawm ua haujlwm. Lub sij hawm ntxuav yog nyob ntawm qhov ntim tank thiab cov yeeb nkab layout; kev hloov pauv nyob ntawm tus naj npawb ntawm cov khoom; Lub sijhawm tos nyob ntawm cov khoom xa tuaj; thiab kev tawg yog nyob ntawm cov khoom siv. Cov no yog kwv yees nyob rau theem tsim thiab yuav tsum tau kho tshiab siv cov ntaub ntawv tsim tawm tiag tiag.
Kev tu yuav siv sijhawm tsawg kawg nkaus: kev ncig, cua sov thiab tawm tsis tuaj yeem hla. Kev txiav txim rau cov khoom qub rau hauv kev khiav ntev dua tuaj yeem tso lub sijhawm ntau lawm, muab kev pov thawj lees paub tias kev khiav haujlwm ntev dua tseem ua tau raws li kev nyiam huv thiab kev ua haujlwm zoo.
Ua hauj lwm los ntawm: los ntawm 3,000 tonnes mus rau ib teev twg
Cov duab hauv qab no yog xav, tsuas yog siv los qhia txoj hauv kev: 3,000 tonnes ntawm puree ib xyoos, 60% tawm los, 200 hnub tsim khoom, ob zaug ua haujlwm tag nrho 16 teev, nrog kev tu ob zaug ib hnub ntxiv txog 2 teev, 1 teev ntawm kev hloov pauv thiab 1 teev tos thiab kev tawg.

Ob lub ntsiab lus tseem ceeb ntawm no. Qhov 60% tuaj txog thaum 45 hnub no piav qhia txog kev faib khoom ntawm cov khoom siv raw txhua xyoo. Nws yog cais los ntawm 60% tawm los, txawm tias cov lej tshwm sim zoo ib yam. 67 tonnes yog qhov nruab nrab noj txhua hnub thaum lub caij ncov; kev noj nyob rau hnub ua haujlwm hnyav tshaj plaws yog siab dua.
Puas yog tsib tonne ib teev kab txaus?
Lub caij nruab nrab xav tau 2.1 tonnes ib teev, yog li 5 tonne kab khiav ze li ntawm 40% ntawm qhov ntsuas, thaum lub ncov xav tau 5.6 tonnes, txog 11% saum toj no.
Ua ntej ntxiv lub peev xwm, xyuas seb lub sijhawm tsim khoom puas tuaj yeem muab sijhawm ua haujlwm ntau dua. Txo kev ntxuav ntawm ob lub voj voog mus rau ib qho txuag ib teev, thiab kev txiav txim rau tib yam khoom tshem tawm 1 teev hloov pauv: 16 - 1 - 0 - 1 tawm 14 teev ntawm kev tsim khoom.
Lub sijhawm no nyob ntawm ob qho xwm txheej. Txo tus naj npawb ntawm kev tu lub voj voog yuav tsum tau ua pov thawj tias kev ua haujlwm ntev dua tseem ua tau raws li kev nyiam huv thiab kev ua haujlwm zoo. Kev lees txais cov neeg siv khoom tsis tuaj yeem hloov qhov kev lees paub no. Kev txiav txim pab pawg nyob ntawm cov khoom thiab hnub xa khoom. Yog tias ob qho xwm txheej tsis tuaj yeem ua tau raws li, suav rov qab siv 13 lossis 12 teev.
Yog tias txoj kab tuaj yeem ua haujlwm rau 14 teev, 67 / 14 muab qhov yuav tsum tau ua ntawm 4.8 tonnes ib teev. Qhov no yog nyob rau hauv lub peev xwm ntsuas, tab sis siv 95% ntawm nws.
Yog tias lub sijhawm teem sijhawm tsis tuaj yeem muab sijhawm 14 teev, xyuas seb lub peev xwm ntsuas cov cuab yeej siv tau npaum li cas thiab theem twg mus txog qhov txwv ua ntej. Siv cov kev tshawb pom no los txiav txim seb qhov kev poob qis hu rau kev nthuav dav, ua los ntawm lwm tus neeg tsim khoom, lossis ib txoj kab tshiab.
Qhov theem twg teev tus nqi?
Pretreatment, pulping, sterilization thiab filling tsis tshua muaj lub peev xwm zoo ib yam, yog li theem qeeb tshaj plaws teev cov zis ntawm kab. Muab piv rau lawv siv tib chav nyob: pretreatment yog nyob rau hauv tonnes ntawm raw txiv hmab txiv ntoo ib teev, thaum sterilization thiab filling yog ntsuas nyob rau hauv tonnes ntawm tiav lawm cov khoom. Hloov ntawm lawv siv cov tawm los. Ntawm 5 tonnes ntawm raw txiv hmab txiv ntoo ib teev twg thiab 60% tawm los, pretreatment muab 3 tonnes ntawm cov khoom ib teev, yog li ib tug steriliser rated ntawm 4 tonnes tsis yog lub limiting theem. Thaum cov units sib phim, sib piv cov peev txheej tiag tiag nrog lub peev xwm ntsuas. Ib theem khiav ntawm nws qhov ntsuas tsis muaj peev xwm seem. Yog tias nws khiav qis dua nws qhov kev ntaus nqi thaum cov khoom tsim ua ntej ntawm nws, kos rau hauv qab rau lwm qhov kev txwv. Qhov kev soj ntsuam no ib leeg tsis ua pov thawj tias theem muaj peev xwm txaus.
Pulping tso cai rau ntau qhov yooj. Lub tank tsis cia cov theem ua ntej thiab tom qab nws khiav ntawm lawv tus kheej tus nqi. Loj lub tank kom npog lub sij hawm downtime xav tau rau kev hloov ntim; nce tank ntim yuav tsum tsis txhob raug kho raws li kev muaj peev xwm ntxiv.
Siv cov chav nyob sib xws kom cov lej tuaj yeem sib piv, suav cov sijhawm ua haujlwm tiag tiag kom tsis txhob muaj qhov xav tau siab tshaj plaws, thiab txheeb xyuas lub fwj dej ua ntej xaiv theem twg los nthuav. Cov tshev no yuav pab txiav txim seb puas xav tau ib kab loj dua.
