Raws li cov khoom lag luam ntawm coke ntau lawm, tar residue tau ncaj qha faib rau coking thee raws li cov pov tseg uas muaj kev phom sij yav dhau los, tab sis vim muaj cov av noo siab ntawm cov tar residue, nws yuav ua rau muaj qee yam cuam tshuam rau ib puag ncig thaum caij tsheb thauj mus los. Txhawm rau ua raws li lub teb chaws "ob chav carbon" lub tswv yim thiab qhov yuav tsum tau ua kom qis qis qis ntawm kev tiv thaiv ib puag ncig, cov nroj tsuag coking tau pib tsom mus rau tag nrho cov txheej txheem ntawm coking thiab kev tswj hwm tag nrho ntawm txhua yam cuam tshuam nrog kev tiv thaiv ib puag ncig, yog li kom ua tiav cov pa phem txo thiab txo cov pa roj carbon monoxide, thiab coj mus rhaub cov peev txheej thiab ua kom muaj txiaj ntsig zoo. Tom qab xa mus rau cov dej num ntawm kev sib sib zog nqus kev kho mob ntawm tar slag nyob rau hauv tsev thiab txawv teb chaws, lub coking cog txiav txim siab mus leach thiab qhuav lub tar slag, uas tsis tau tsuas yog txo cov noo noo cov ntsiab lus ntawm tar slag thiab nce cov tar ntau lawm, tab sis kuj txo tus naj npawb. ntawm lub sij hawm ntawm thauj tar slag, zoo tshem tawm cov ntxhiab tsw volatilized nyob rau hauv tus txheej txheem ntawm rub thiab thauj, txhim kho qhov chaw ib puag ncig, thiab paub txog kev sib koom ua ke ntawm ib puag ncig, kev lag luam thiab kev sib raug zoo.
Tar slag leaching ntaus ntawv yog lub zog-txuag thiab ib puag ncig-phooj ywg ntaus ntawv rau leaching thiab kev tiv thaiv ib puag ncig kev kho mob ntawm tar slag nyob rau hauv ib nrab lub xeev. Cov tar thiab ammonia sib tov nyob rau hauv lub nkoj tar yog sib cais los ntawm lub cev, thiab tom qab ntawd cov tar residue yog precipitated rau hauv qab ntawm lub nkoj tar, scraper los ntawm scraper mus rau qhov chaw nres nkoj ntawm lub nkoj tar thiab ces poob mus rau tar residue draining. ntaus ntawv.
Nyob rau hauv qhov xwm txheej kaw, tar slag yog sau - liquefied - crushed - hauv av - conveyed --Kev sib cais thiab lwm yam kev ua, cov thee tar thiab slag hmoov nyob rau hauv lub tar slag yog zoo sib cais. Cov tar sib cais tuaj yeem muag tau, cov ammonia yog rov qab siv rau hauv cov kab ke ammonia, thiab cov tar slag tau xa mus rau cov nroj tsuag thee rau cov thee faib, uas ua rau cov txiaj ntsig ntawm tar slag los ntawm "noj nws".
Nyob rau hauv xyoo tas los no, TISCO Coking Plant tau tsom mus rau kev tsim "tus qauv ntawm kev lag luam coking kom ruaj khov", tsom mus rau kev tsim cov nroj tsuag huab cua tiv thaiv ib puag ncig, tsis tu ncua ua cov txheej txheem siab hloov pauv thiab txhim kho hauv kev kho cov pa phem thiab rov ua dua tshiab, ultra-low emission. thiab ultra-low emissions, txuag hluav taws xob thiab txo cov pa roj carbon monoxide, kev thauj mus los huv, thiab lwm yam, thiab tau ua tiav cov kev thauj mus los huv si ntawm cov tsheb ciav hlau, kev kho VOCs, dej phwj kaw, thiab lwm yam. VOCs kho, cesspool kaw thiab tshem tawm tsw, coke cub gas qhov chaw ultra huv emission txo, coke cub flue gas desulfurization thiab denitrification upgrade, coking wastewater reuse thiab lwm yam kev tiv thaiv ib puag ncig kev kho tej yaam num. Los ntawm kev ua lag luam tsis tu ncua thiab cov txheej txheem siab ua haujlwm ntawm cov chaw tiv thaiv ib puag ncig, TISCO coking cog tau ua tiav lub hom phiaj ntawm qhov tsis pom qhov pom, tsis muaj suab nrov, tsis muaj ntxhiab tsw, thiab kev tswj ob npaug ntawm emission concentration thiab tag nrho cov nyiaj. Cov txheej txheem coking emissions ntawm cov pa phem loj tshaj li tam sim no lub teb chaws tus qauv kev nce qib ntawm ntau tshaj 50 feem pua, tau mus txog lub ultra-low emission yuav tsum tau ntawm Shanxi xeev, thiab ua kev lag luam tus ntsuab low-carbon kev loj hlob ntawm lub lag luam benchmark.
