Txheej txheem cej luam ntawm Kev Txhim Kho Cov Plua Plav Tshem Tawm Technology: Daim ntawv thov thiab kev tsim cov tshuab tshem tawm plua plav yog sib txuas nrog cov txheej txheem ntawm industrialization hauv kuv lub teb chaws. Kev tshem tawm plua plav thev naus laus zis feem ntau suav nrog kev tshem tawm cov plua plav tawm, tshem cov plua plav ntub dej, tshem tawm cov plua plav electrostatic, thiab tshem tawm cov plua plav hauv hnab.
Kev tshem tawm cov plua plav siv tshuab siv cov av gravitational, inertia, lossis centrifugal quab yuam kom cais cov plua plav. Nws tshem tawm efficiency feem ntau yog qis dua 90%; thaum nws tus yam ntxwv los ntawm kev ua haujlwm qis dua, nws muaj kev ua haujlwm qis thiab muaj zog -ntau.
Kev tshem tawm cov plua plav ntub dej siv lub hauv paus ntsiab lus ntawm cov pa roj- ua kua sib chwv txhawm rau hloov cov hmoov av los ntawm cov plua plav- cov roj ntws mus rau hauv cov kua nruab nrab, yog li tshem cov plua plav tawm ntawm cov pa. Nws txoj kev tshem tawm yog me ntsis siab dua li ntawm cov txheej txheem siv tshuab, tab sis nws muaj kev pheej hmoo ua rau muaj kuab paug thib ob los ntawm cov kua nplaum.
Electrostatic plua plav tshem tawm cuam tshuam nrog kev hla cov plua plav-laden roj los ntawm cov hluav taws xob muaj zog kom hluav taws xob them cov plua plav. Raws li cov khoom hla ntawm cov plua plav- khaws cov electrodes, qhov zoo lossis qhov tsis zoo ntawm cov khoom raug nyiam thiab adsorbed los ntawm cov hlau tsis zoo lossis cov electrode zoo, yog li tshem cov plua plav tawm ntawm cov pa roj. Electrostatic precipitators muaj kev tshem tawm siab; Txawm li cas los xij, lawv cov kev ua tau zoo yog cuam tshuam los ntawm cov plua plav hluav taws xob tiv thaiv, uas tuaj yeem ua rau kev ua haujlwm tsis ruaj khov. Txij li xyoo 1990, electrostatic precipitators tau siv dav hauv kev tswj cov pa roj paug hauv ib puag ncig uas muaj qhov kub thiab txias, ntim roj ntau, thiab kev ua haujlwm nyuaj- xws li hauv thermal fais fab nroj tsuag thiab cement kilns.
Baghouse plua plav tshem tawm siv fiber ntau lim xov xwm los ntes cov khoom sib cais los ntawm cov plua plav-laden gas kwj, tsim "filter ncuav mog qab zib" ntawm cov plua plav. Lub ncuav mog qab zib lim no ua haujlwm raws li txheej txheej lim dej ntxiv kom ntes tau cov plua plav zoo dua, yog li ua tiav cov plua plav tshem tawm tau zoo. Baghouse thev naus laus zis tuaj yeem ua tiav qhov kev tshem tawm siab heev, nrog cov plua plav emissions uas yuav poob qis dua 5 mg / m³; Tsis tas li ntawd, nws qhov kev ua tau zoo tsis cuam tshuam los ntawm cov yam ntxwv ntawm plua plav xws li hluav taws xob tiv thaiv. Feem ntau, cov hmoov av uas muaj txoj kab uas hla tsawg dua 10 microns (piv txwv li, inhalable particulate matter) ua rau muaj kev pheej hmoo loj rau tib neeg kev noj qab haus huv; baghouse filters qhia tau hais tias muaj kev sib cais siab heev rau xws li inhalable particulates. Daim ntawv thov Scope ntawm baghouse lim hauv kev kho cov pa paug paug ntawm qhov kub thiab txias (<120°C) has been steadily expanding.
Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis-xws li siab- qhov kub thiab txias- tiv thaiv lim xov xwm thiab mem tes- dav hlau ntxuav tshuab- cov lim hnab hauv tsev tam sim no tau txais kev nthuav dav ntxiv hauv kev kho mob siab - kub thiab siab -concentration flue ua tsaug rau lawv cov kev ua haujlwm zoo dua. Nrog rau kev nrawm nrawm ntawm kev lag luam thiab kev lag luam hauv nroog, huab cua hauv kuv lub teb chaws tau dhau los ua hnyav zuj zus, thiab cov qauv emissions rau atmospheric pollutants tau nce zuj zus. Yog li ntawd, siab -cov cuab yeej tshem tawm plua plav tawm tau zoo-tshwj xeeb electrostatic precipitators thiab lub hnab lim{11}} tau txais ntau daim ntawv thov. Tam sim no, electrostatic nag lossis daus thiab hnab lim sawv cev rau cov thev naus laus zis tshem tawm plua plav hauv kuv lub tebchaws.
Piv rau electrostatic precipitators, lub hnab lim dej muaj qhov zoo sib xws ntawm kev txuag hluav taws xob thiab txo qis emission. Muab cov ntsiab lus tseem ceeb ntawm cov qauv kev tso tawm hauv lub tebchaws uas muaj zog zuj zus tuaj, kev siv lub hnab lim dej tau npaj los ua thawj lub tswv yim los tswj cov pa phem.
Txheej txheem cej luam ntawm Kev Lag Luam Cov Khoom Siv Tshem Tawm: Cov khoom siv tshem tawm plua plav feem ntau yog siv hauv kev lag luam uas muaj plua plav hnyav heev -xws li cov cement, steel, tsis yog -ferrous hlau, hluav taws xob, machinery, tshuaj, thiab khib nyiab incineration. Txoj hauv kev ntawm cov khoom siv tshem tawm cov plua plav kev lag luam tag nrho cov nqi tsim tawm yog sib cuam tshuam nrog kev lag luam hauv tsev thiab thoob ntiaj teb, nrog rau cov xwm txheej ntawm kev lag luam downstream. Nyob rau hauv xyoo tas los no, kuv lub teb chaws tus nqi tso tawm tag nrho (cov nyiaj tau los ntawm kev muag khoom) rau cov khoom siv tshem tawm plua plav tau muaj kev hloov pauv; nce los ntawm 13.998 billion RMB hauv 2005 txog 29.007 billion RMB hauv xyoo 2008, kev lag luam tau ua tiav qhov kev loj hlob txhua xyoo ntawm 27.49%. Xyoo 2009, cuam tshuam los ntawm kev kub ntxhov thoob ntiaj teb, kev loj hlob ntawm cov haujlwm tseem ceeb-xws li cov cement, steel, tsis yog{12}}ferrous hlau, thiab tshuab{13}} tau poob qis; tus nqi tsim tawm ntawm qee qhov kev lag luam txawm tias tau cog lus, ua rau ib ntus, me ntsis poob qis hauv tag nrho cov txiaj ntsig ntawm kuv lub teb chaws cov khoom siv tshem tawm plua plav.
