Coal ntxuav txoj kev yog muab faib ua hom ntub thiab qhuav hom txheej txheem.Coal-ntxuav cov dej khib nyiab yog cov dej ntws tawm hauv cov txheej txheem ntub dej.Thaum lub sijhawm ua haujlwm no, kev siv dej yuav tsum tau los ntawm txhua tuj ntawm cov thee ntawm 2m3 txog 8m3.

Cov dej khib nyiab uas tsim los ntawm cov txheej txheem no zoo li yuav nyob twj ywm opaque txawm tias sab laug rau ob peb lub hlis.Ib tug loj npaum li cas ntawm cov thee ntxuav cov dej khib nyiab yog tso tawm yam tsis tau mus txog tus qauv, uas ua rau cov dej paug, dej-channel blockage, thiab tag nrho cov nyob ib ncig ntawm ecological puas.

HaiBar Belt Lim Xovxwm
Los ntawm kev koom tes nrog ntau qhov loj-loj cog nroj tsuag, HaiBar tau tshaj tawm txoj siv lim xovxwm rau kev tshawb fawb txog kev siv engineering ntawm ob qho tib si thee ntxuav dej khib nyiab thiab slime lub cev qhuav dej.Qhov tshwm sim qhia tau hais tias txoj siv lim xovxwm rau slime lub cev qhuav dej yog qhov ua tau zoo ntawm cov thev naus laus zis thev naus laus zis, muaj peev xwm ua tau zoo, limpid filtrate, cov ntsiab lus dej tsawg ntawm cov ncuav mog qab zib lim, thiab kaw lub voj kaw dej rau thee ntxuav, thiab lwm yam.

Ib tsob ntoo thee hauv Anhui Xeev tau siv "cyclone-slime sedimentation tank-filter press" txheej txheem kho.Yog li ntawd, cov sludge tsim muaj qee cov khoom tawv tawv, uas tuaj yeem yooj yim abrade cov ntaub lim.Xav txog cov yam ntxwv sludge no, peb lub tuam txhab xaiv cov ntaub ntawv zoo tshaj plaws thiab hnav-resistant lim ntaub.Ntau lub tuam txhab tau yuav peb cov khoom los hloov cov thawj chamber lim xovxwm lossis phaj-thiab-them lim xovxwm, tom qab mus xyuas peb cov khoom siv ua haujlwm.

1. Lub Rau Hli, 2007, Huainan Xieqiao Coal Company hauv Anhui Xeev tau xaj ob HTB-2000 series siv lim xovxwm.
2. Lub Xya Hli, 2008, Huainan Xieqiao Coal Company hauv Anhui Xeev tau yuav ob lub HTB-1500L series siv lim xovxwm.
3. Thaum Lub Xya Hli, 2011, Hangzhou Environmental Protection Academy ntawm Tuam Tshoj Coal Science Research Institute tau xaj ib HTBH-1000 series siv lim xovxwm.
4. Lub Ob Hlis, 2013, ib HTE3-1500 series siv lim xovxwm raug xa tawm mus rau Turkey.
