Kev xaiv raug-thiab kev teeb tsa kom raug- yog qhov tseem ceeb sib npaug.
3) Kev cuam tshuam thiab kev kub siab hloov pauv kev ua haujlwm: tuav cov xwm txheej tsis ruaj khov
Kev thauj tailings tsis yog qhov chaw kuaj mob. Koj yuav ntsib:
Fluctuating solid concentration
Siab shocks thaum lub twj tso kua mis pib / nres
Sudden siab spikes tom qab ib nrab blockages
Coarse hais los yog khoom txawv teb chaws nyob rau hauv slurry
Pipelines haum rau tailings daim ntaub ntawv feem ntau tsom rau cov qauv kev ruaj ntseg nyob rau hauv siab transients.
Lawv tau tsim los rau qhov tseeb tias "lub kaw lus zoo li ruaj khov- txog thaum nws tsis yog tam sim ntawd."
4) Smoother Inner Walls thiab Predictable Resistance: Zoo zog thiab twj tso kua mis Planning
Hauv kev thauj khoom slurry, kev siv hluav taws xob feem ntau ua kom muaj zog los ntawm cov kav dej ua haujlwm dhau sijhawm - tsis yog lub twj tso kua mis tsis muaj peev xwm.
High resistance ua rau:
Kev xav tau lub zog loj dua lossis cov twj tso kua mis ntxiv
Cov nqi khiav lag luam nce ntxiv
Forced siab dua velocities los tiv thaiv sedimentation, accelerating hnav
Txo qhov system margin thiab muaj kev pheej hmoo siab dua nyob rau hauv kev hloov pauv
Lub qhov dej - tsimslurry kavstabilizes cov qauv ntws thiab ua kom muaj kev tiv thaiv kev kwv yees - yog li cov nqi hluav taws xob tuaj yeem suav tau raug thaum tsim.
5) Lub neej voj voog tus nqi kom zoo: Qhov Kev Ntsuas Tiag Tiag yog Tag Nrho Cov Tswv Cuab Tus Nqi
Ib qho kev sib tw yuav khoom yog qhov zoo li tus nqi siab dua ntawm cov kav dej slurry.
Tab sis tailings systems yuav tsum tau soj ntsuam thoob plaws lawv lub neej voj voog:
Tus nqi yuav khoom
Kev teeb tsa tus nqi
Kev poob qis
Kev tu ntau zaus thiab kev ua haujlwm
Cov khoom seem ntawm cov khoom lag luam siab
Ib puag ncig thiab kev nyab xeeb raug cuam tshuam
Yog tias ib qho kev kaw nqi ntau dua tus nqi sib txawv ntawm cov kav dej, ces qhov kev xaiv "pheej yig dua" yuav yog qhov kim tshaj plaws.
Qhov no yog vim li cas ntau qhov haujlwm tau hloov mus rau cov kav dej tshwj xeeb slurry.
III. Qhov twg Lawv xa tus nqi tshaj plaws?
Lawv qhov zoo tshaj plaws yog pom tseeb hauv:
Ntev - ncua kev thauj mus los ntawm kev cog qoob loo mus rau tailings cia chaw
Qhov ntev ntawm txoj kab, tus nqi ntawm cov dej xau thiab kev kho dua siab dua - kev ntseeg tau yog qhov tseem ceeb dua li kev txuag cov khoom me me.
High -khoom- cov ntsiab lus, abrasive tailings heev
Cov khoom nyuaj thiab siab concentration sai sai hnav cov kav dej txheem.
Complex routing nrog ntau lub luj tshib thiab nce siab hloov
Hnav cov concentration thiab siab hloov pauv yuav tsum muaj kev daws teeb meem ntxiv.
Ib puag ncig kev ua raws cai nruj
Cov kev pheej hmoo tsis txaus ua rau muaj kev tswj hwm thiab lub koob npe nrov.
Kev ua haujlwm tsis tu ncua ib puag ncig uas downtime yog kim
Qhov tsawg dua koj lub kaw lus tuaj yeem nres, qhov kev pheej hmoo ntau yuav tsum tau txo qis ua ntej.
IV. Qhov twg Projects feem ntau mus yuam kev
Qhov teeb meem feem ntau tsis yog lub raj xa dej nws tus kheej -tab sis kev hloov kho tsis zoo.
1) Tsom ntsoov rau kev hnav tsis kam, tsis quav ntsej txog kev ua haujlwm
Siab -cov ntsiab lus hnav feem ntau yog nyob hauv zos.
Txheeb xyuas thiab txhawb nqa lub luj tshib, tees, reducers, thiab valve seem es tsis txhob siv cov kev qhia tshwj xeeb thoob plaws.
2) Kev teeb tsa zoo txiav txim siab ib nrab ntawm Kev Pabcuam Lub Neej
Kev tsis sib haum xeeb, kev txhawb nqa tsis txaus, thermal expansion tsis saib xyuas, thiab kev tswj kev vibration teeb meem txhua yam luv luv lifespan.
Lub twj tso kua mis buffering thiab kev txhawb nqa cov txheej txheem yuav tsum tau txhais nyob rau hauv kev npaj kev tsim kho -tsis improvised.
3) Flow Velocity and Solid Control: Sib Nqus Deposition thiab Tshaj -Hloov
qeeb dhau → sedimentation thiab blockage.
Ceev heev → ceev erosion.
Lub twj tso kua mis-pipe-valve-elbow-elevation system yuav tsum tau sib npaug tag nrho.
4) Kev Txhim Kho Kev Txhim Kho yuav tsum tau tsim ua ntej

Hloov cov seem
Spare xeem standardization
Tiv thaiv kev soj ntsuam zaus thiab cov ntaub ntawv
Kev ntseeg tau tsuas yog ua tiag tiag thaum kos rau hauv kev npaj ua haujlwm.
V. Muab piv li cas tsis tau hlawv
Yog tias nws yog koj thawj zaug yuav khoomcov kav dej slurry, xav tshaj "Puas hnav-resistant?"
Nug cov neeg muab khoom rau:
Cov xwm txheej -raws li cov lus xaiv xaiv
Muab cov ntsiab lus khoom, qhov loj me, ntws tus nqi, siab, kub, qhov deb, qhov siab, lub luj tshib, hom twj tso kua mis, thiab pib- nres zaus.
Cov npe kev teeb tsa rau siab - hnav nodes
Lub luj tshib, tees, reducers, seem valve, lub twj tso kua mis -cov no txhawb li cas?
Tag nrho cov nqi ntawm cov tswv cuab sib piv
Kev pab lub neej hauv paus, txij nkawm lub voj voog, kev npaj khoom seem.
Clear kev xa khoom
Khoom siv, khoom siv, kev txhawb nqa, kev taw qhia kev teeb tsa, cov lus teb mechanisms.
Cov neeg muab khoom muaj peev xwm ntawm kev daws teeb meem
Tailings thauj tsis yog qhov chaw sim-nrhiav cov neeg koom tes uas txuas kev tsim, muab khoom, kev taw qhia kev tsim kho, thiab kev saib xyuas lub tswv yim.
VI. Vim li cas Muaj ntau qhov project hais txog cov neeg tsim khoom nyiam Luoyang Zhengju?
Hauv kev sib piv qhov project, tuam txhab uas muag nrog cov ntaub ntawv pov thawj engineering thiab cov txheej txheem - feem ntau nyiam vim tias:
Lawv tsis tsuas yog muag cov kav dej xwb- lawv txheeb xyuas cov haujlwm ua haujlwm.
Lawv tsis tsuas yog muab cov kev txwv -lawv qhia meej siab - coj cov nodes, cov qauv kev sib txuas, thiab cov ntsiab lus ntawm kev teeb tsa.
Lawv tsis tos txog teeb meem-lawv hloov kev pheej hmoo mus rau hauv kev xaiv thiab teeb tsa theem.
Tus nqi tiag tiag nyob rau hauv kev hloov koj cov tailings thauj los ntawm "kev tua hluav taws tas li" mus rau "kev npaj ua haujlwm."
Yog tias koj tab tom npaj los tsim lub tsheb thauj khoom tailings, sau koj cov kev ua haujlwm rau ib nplooj ntawv thiab thov cov xwm txheej -raws li daim ntawv thov thiab teeb tsa- nws yuav ua rau kev sib piv kom meej thiab sai dua.
