Smog yog ib qho piv txwv ntawm huab cua phem heev.Peb muaj kev nkag siab tob txog qhov tsis yooj yim uas coj los ntawm smog rau peb lub neej.Nws tsis yog tsuas yog ib qho teeb meem ntawm kev nyab xeeb kev mus ncig, tab sis kuj cuam tshuam rau peb txoj kev noj qab haus huv.Ib qho laj thawj tseem ceeb rau kev tsim cov smog yog qhov emission ntawm "xim pa luam yeeb plumes", yog li kev tswj hwm ntawm "xim pa luam yeeb plumes" yog tus yuam sij rau kev tswj hwm huab cua, thiab nws yuav tsum tau ua tib zoo saib xyuas cov pa luam yeeb dawb.
Dr. He Ping tau tawm tswv yim txog kev tswj hwm kev nyab xeeb tseem ceeb hauv xyoo 2017, suav nrog kev nthuav dav ntawm ultra-ntxuav emissions, tswj kev ua qias tuaj ib puag ncig, kev tshuaj xyuas ib puag ncig, kaw lossis tawm-peak ntau lawm, hloov cov thee rau roj, thiab tswj "xim plumes. ”, thiab lwm yam, txhawm rau txhim kho cov qauv emission., txhawm rau txhawb nqa cov pa tawm ultra-ntxuav, tswj cov kuab paug tawg, kaw tshwj xeeb cov chaw ua pa phem, tswj cov chaw tsis muaj kev cia siab, thiab cov neeg soj ntsuam ib puag ncig tau xa ncaj qha los ntawm lub chaw kom ntseeg tau tias kev ua raws cai, thiab lwm yam, thiab tau txais lub luag haujlwm tseem ceeb.
Tus nqi ntawm kev kaw lossis staggered ntau lawm yog siab dhau.Thaum lub qhov cub tawg ntawm lub tshuab steel yog qhib thiab tawm, qhov poob yuav ntau pua lab.Txoj kev no tsuas yog nkag siab tias yog kev daws teeb meem ib ntus thiab tsis tuaj yeem txuas ntxiv mus.Lub tswv yim "coal-to-gas" tau dhau mus dhau lawm thiab kev thov tau qeeb.Txoj hauv kev tiag tiag rau lub hom phiaj ncaj qha rau cov smog yog tswj hwm "xim plumes", uas tam sim no tsuas yog ua tiav hauv qee thaj chaw xws li Zhejiang, Shanghai, Tianjin, thiab Tangshan.
Dr. He Ping kuj piav qhia tias vim li cas kev tswj hwm "xim plumes" yog tus yuam sij rau kev tswj hwm huab cua.Lub npe hu ua "coloured plume" yog cov roj av ntub dej uas tso tawm los ntawm feem ntau cov thee hluav taws xob hluav taws xob, cov nroj tsuag steel, cua sov boilers, thiab lwm yam tom qab ntub dej desulfurization.Cov roj av ntub dej muaj ntau cov hmoov tshauv zoo, ammonium sulfate, sulfuric acid.Ultrafine hais xws li calcium thiab calcium nitrate, thiab lwm yam, ncaj qha ua PM 2.5 hauv huab cua.Nyob rau hauv cov huab cua zoo li qub thiab ruaj khov, cov fumes ntub dej ntxiv adsorb cov pa phem tawm los ntawm cov chaw tsim khoom thiab tsheb.Los ntawm kev tawm tsam ntawm lub cev thiab tshuaj lom neeg, "kev nqus dej nce ntxiv" thiab cov teeb meem thib ob tshiab tshwm sim, uas ua rau muaj qhov tsis zoo ntawm huab cua tsis zoo thiab ua rau muaj huab cua phem heev.
Cov txheej txheem ntub dej desulfurization tau siv dav siv 200,000 tons ntawm cov dej vapor rau hauv huab cua txhua teev, suav txog 80% ntawm cov dej tawm dag zog.Yog li ntawd, tus yuam sij rau kev tswj hwm haze yog txo cov av noo hauv cov pa roj, thiab ua "dehumidification thiab whitening" ntawm "xim plumes" los ntawm desulfurization, thiaj li txo cov ya raws tawm hauv huab cua, thiab tib lub sijhawm. txo cov ultra-fine hais tawm nrog cov roj flue.feem ntau.Tam sim no muaj cov thev naus laus zis ntawm "dehumidification thiab whitening" thev naus laus zis, suav nrog txoj kev qhuav, txoj kev sodium, flue gas pov tseg thaum tshav kub kub rov qab, tshuaj tsuag dehumidification, thiab lwm yam, uas tau siv los hloov cov thee hluav taws xob boilers hauv qee lub nroog.
