Tsom ntsoov rau LIKE — Guodian Changyuan Jingmen 2 × 640mw tshuaj dej system muaj peev xwm nthuav dav thiab tsim kho qhov project

Vim tias qee cov khoom siv thermal hauv lub tshuab hluav taws xob tuaj yeem cuam tshuam los ntawm qee yam khoom hauv dej, ua rau muaj kev puas tsuaj rau cov khoom siv thiab cov khoom siv corrosion, kev nyab xeeb ntawm lub tshuab hluav taws xob yog ncaj qha cuam tshuam nrog kev kho dej tshuaj. Kev puas tsuaj ntawm impurities hauv dej rau cov cuab yeej txiav txim siab tias cov dej hauv lub tshuab fais fab yuav tsum tau kho ua ntej nws tuaj yeem siv tau. Qhov kev kho no yog kev kho dej tshuaj lom neeg hauv lub tshuab fais fab. Txoj kev loj hlob ntawm chemical water treatment technology nyob rau hauv fais fab nroj tsuag Muaj peb txoj kev tseem ceeb rau lub fais fab nroj tsuag kom tau cov ntshiab demineralized dej: (1) cov tsoos clarification, pom + ion pauv txoj kev yog saws, thiab cov txheej txheem yog raws li nram no: Raw dej → Flocculation clarifier → multi-media filter → activated carbon filter → cation exchange bed → carbon dioxide tshem tawm kiv cua → intermediate water tank → anion exchange bed → anion and cation exchange bed → resin trapper → unit water. (2) Rov qab osmosis + sib tov lub txaj dej ntau lawm txoj kev yog saws, thiab cov txheej txheem yog raws li nram no: Raw dej → flocculation clarifier → multi-media lim → activated carbon lim → precision lim → kev ruaj ntseg lim → siab twj tso kua mis → rov qab osmosis ntaus ntawv → intermediate dej tank → mix txaj → resin trapper → demineralized dej tank. (3) Pretreatment, rov qab osmosis + EDI dej ntau lawm txoj kev yog saws, thiab cov txheej txheem yog raws li nram no: Raw dej → flocculation clarifier → multi-media lim → activated carbon lim → ultrafiltration ntaus ntawv → rov qab osmosis ntaus ntawv → rov qab osmosis dej tank → EDI ntaus ntawv → microporous lim → demineralized dej tank. Cov dej tshuaj lom neeg ntawm lub tshuab fais fab yog qhov nyuaj thiab muaj cov kev xav tau siab rau cov kua qaub, alkali thiab corrosion kuj ntawm li qub. Peb lub tuam txhab pab cov neeg siv khoom xaiv cov qauv ua ke raws li kev ua haujlwm ntawm qhov chaw thiab muab cov phiaj xwm ua tau raws li kev ua haujlwm thiab txuag nyiaj txiag. Cov khoom lag luam thiab cov kev pabcuam tau raug qhuas los ntawm cov neeg siv khoom! LIKE li qub feem ntau muab npauj npaim li qub, diaphragm li qub, lub ntiaj teb li qub, npauj npaim kos li qub, thiab lwm yam Stainless hlau Cov tshuaj chloride ion corrosion kuj tus qauv ntawm stainless hlau tuaj yeem pom zoo kom pom zoo los ntawm kev xa mus rau kev kho dej ntawm thermal fais fab nroj tsuag: (1) Service Ib puag ncig ntawm T304 stainless hlau: chloride ion ntsiab lus yog 0-200mg / L (2) Kev pabcuam ib puag ncig ntawm t316 stainless hlau: chloride ion ntsiab lus yog ＜ 1000mg / L (3) Kev pabcuam ib puag ncig ntawm t317 stainless hlau: chloride ion ntsiab lus yog ＜ 5000mg / L Raws li GB 50235-2010 code rau kev tsim kho ntawm industrial hlau pipeline engineering thiab GB 50184-2011 code rau kev lees txais kev tsim kho zoo ntawm industrial hlau pipeline engineering, cov ntsiab lus ntawm chloride ion hauv dej yuav tsum tsis pub tshaj 25mg / L (25ppm). Kev ntsuam xyuas hydraulic yuav tsum ua raws li cov cai hauv qab no, thiab cov dej huv yuav tsum tau siv rau kev ntsuas hydraulic. Thaum kuaj stainless hlau, npib tsib xee thiab npib tsib xee alloy kav lossis cov kav dej txuas nrog stainless hlau, npib tsib xee thiab npib tsib xee alloy kav lossis cov khoom siv, cov ntsiab lus chloride ion hauv dej yuav tsum tsis pub tshaj 25mg / L (25ppm) Yuav ua li cas txog chloride ion corrosion kuj ntawm duplex stainless hlau ? Kev ua tau zoo li cas? Kev tiv thaiv corrosion ntawm duplex stainless hlau 2101, 2304, 2205 thiab 2507 yog ntau dua li ntawm 316L stainless hlau zoo tib yam, thiab qee cov ntaub ntawv sib npaug rau super stainless hlau. Piv txwv li, pitting corrosion kuj ntawm 2507 stainless hlau yog piv rau 254SMO stainless hlau, thiab chloride ion pitting corrosion kuj ntawm 2205 stainless hlau yog sib npaug rau 904L stainless hlau. Vim li cas diaphragm li qub xaiv cov roj hmab tag nrho? 1. Cov roj hmab mos diaphragm valve tuaj yeem txiav tawm qhov nruab nrab yam tsis muaj qhov xau. 2. Vim tias cov roj hmab muaj qee qhov kev tiv thaiv corrosion, ua ntej xyoo 1960, tsis muaj cov khoom siv corrosion-resistant zoo dua. Diaphragm li qub feem ntau tau txhawb nqa thiab siv los ua cov khoom siv tiv thaiv corrosion, thiab tseem mus ntxiv rau tam sim no. 3. Txoj kev khiav yog qhov yooj yim thiab muaj lub luag haujlwm ntawm "kev tu tus kheej", uas tuaj yeem siv rau cov xov xwm tsis huv. 4. Lub diaphragm ua los ntawm mos sealing xws li roj hmab los yog yas muaj zoo sealing kev ua tau zoo Cov neeg siv tswv yim Cov neeg siv khoom qhov chaw yog high-end thiab muaj kev xav tau siab rau qhov zoo ntawm cov khoom siv li qub. Cov neeg siv khoom txaus siab heev nrog cov khoom ntawm LIKE li qub. Qhov kev koom tes no tau txais kev qhuas heev los ntawm cov neeg siv khoom thiab kev koom tes zoo heev. Nws txaus siab tuav kev koom tes ntev nrog LIKE li qub. Qhov tseem ceeb ntawm lub valve Nrog kev nce qib ntawm kev lag luam kev sib raug zoo, kev cog hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev sib raug zoo. Yog li ntawd, tsuas yog los ntawm kev siv tshuaj kho dej kom zoo thiab ua kom cov dej zoo, tuaj yeem txhim kho kev kho dej ntawm lub tshuab hluav taws xob thiab cov txiaj ntsig kev lag luam ntawm lub tshuab fais fab. Kev kho dej tshuaj lom neeg yog tus yuam sij los txhim kho lub zog tsim hluav taws xob ntawm lub tshuab hluav taws xob. Nws ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ruaj khov ntawm cov khoom siv thermal. Nws yog ib qho tseem ceeb txheej txheem txhais tau tias kom tsis txhob scale los yog ntsev tsub zuj zuj nyob rau hauv cov txheej txheem ntawm dej ncig. Lub hom phiaj ntawm kev txheeb xyuas thiab kawm txog kev siv tshuaj kho dej hauv cov tshuab fais fab yog txhawm rau txhim kho kev kho dej kom zoo, txo cov nqi tsim hluav taws xob, thiab txhim kho kev lag luam thiab kev sib raug zoo. Valves ua lub luag haujlwm tseem ceeb hauv cov kav dej ntawm kev kho dej tshuaj. Kev nyab xeeb thiab txuag, LIKE VALVE Pab koj!
