Vim li cas Hnav -Resistant Gravel Pumps Indispensable rau Fais Cog Desulfurization Systems?
Hauv cov txheej txheem FGD ntub, cov twj tso kua mis tsis txav dej huv. Lawv tuav cov slurry loaded nrog limestone thiab gypsum hais, feem ntau ntawm 20-30% cov khib nyiab los ntawm qhov hnyav - thiab denser ntawm underflow thiab los ntshav cov ntsiab lus. Cov khoom yog tawv thiab angular, scouring sab hauv ntawm ob peb meters ib ob. Tus qauv centrifugal twj tso kua mis nrog lub cam khwb cia hlau impeller thiab nyias -walled casing tsis tuaj yeem coj cov kev txiav zoo li ntawd. Nyob rau hauv tsawg tshaj li ib hlis, lub impeller tshiab tuaj yeem raug hollowed, clearances qhib, thiab ob qho tib si ntws thiab lub taub hau poob hauv qab qhov txheej txheem xav tau.
Thaum lub recirculation los yog gypsum bleed twj tso kua mis mus, absorber ncig poob. Gas-kev sib cuag ua kua raug kev txom nyem, thiab SO₂ tshem tawm kev ua tau zoo swb ncaj nraim ntawm qhov kev tsim nkhaus. Yog tias pawg emissions hla qhov kev tso cai txwv, cov nroj tsuag ntsib ntau dua li kev nplua hnyav - nws tuaj yeem raug yuam kom derate lossis kaw. Rau qhov chaw nres tsheb fais fab tsis tu ncua, qhov ntawd yog qhov tsis txaus ntseeg. Lub twj tso kua mis tsuas yog tuav txoj kab.
Abrasion-cov twj gravel tiv taus yog tsim tshwj xeeb rau cov kev pabcuam no, thiab lawv cov kev tsim kho zoo li tsis muaj dab tsi zoo li lub twj tso kua dej. Feem ntau siv ob lub casing: lub plhaub tawv tawv hlau sab nraud uas ua haujlwm siab, thiab hloov tau sab hauv hauv ob sab phlu - siab -chrome alloy lossis roj hmab - uas coj ncaj qha hnav. Qhov kev tshem tawm ntawm lub impeller thiab qhov nqus dej - sab liner raug kho sab nraud nrog cov jacking bolts. Tsis tas yuav rhuav lub twj tso kua mis; tom qab khiav-hauv, koj tsuas yog hu rau qhov kev tshem tawm rov qab mus rau lub Hoobkas spec thiab rov ua haujlwm ntawm qhov chaw.
Cov hydraulics yog tsim nyob ib ncig ntawm slurry. Impeller passages tau nthuav dav thiab cov vane suav raug txo, yog li cov khoom loj thiab cov khib nyiab siab dhau los ntawm tsis muaj ntsaws. Qhov no tseem txo qis qhov nrawm nrawm, txo qhov cuam tshuam lub zog ntawm cov khoom.
Cov khoom siv xaiv tsav lub neej ua haujlwm. Rau limestone-gypsum slurry, siab -chrome alloy zoo li Cr27 yog ib qho mus- mus; Thaum tshav kub kub-kho, nws saum 60 HRC thiab tiv taus qhov hnav ntawm cov khoom tawv. Qhov twg chlorides siab los yog hnyav yog ib qho kev txhawj xeeb, cov roj hmab ntuj - cov twj tso kua mis yog cov lus pom zoo - cov roj hmab elasticity absorbs particle cuam tshuam, thiab nws tswj cov tshuaj tua kab mob zoo. Qee qhov xwm txheej, silicon carbide- cov khoom sib txuas ntxiv txhawb nqa kev yaig kuj tseem ntxiv. Nrog rau cov ntaub ntawv no, ntub dej- kawg lub neej ncav cuag li ob peb lub lis piam mus rau ib xyoos lossis ntau dua.
Kev saib xyuas muab FGD pab neeg ua pa tiag tiag. Lub rotating sib dhos feem ntau yog tawm los ua ib daim cartridge tiav. Koj tuaj yeem hloov lub impeller, liners, thiab hnav daim hlau yam tsis tau txav lub tshuab nqus tsev lossis tso cov kav dej lossis lub cev muaj zog. Cov neeg ua haujlwm tuaj yeem tshem tawm qhov kev hloov kho loj hauv ob peb teev thiab tau txais lub twj tso kua mis rov qab rau hauv kab. Hnav tuaj yeem kwv yees tau, yog li kev npaj cov khoom seem tau yooj yim dua - yuav ua ntej raws li cov sijhawm ua haujlwm es tsis txhob them cov nqi them ceev. Lub qhov rais tau teem tseg txij nkawm ncaj qha nqa lub kaw lus lub sijhawm ua haujlwm txhua xyoo.
Ntawm daim ntawv, lub twj tso kua mis gravel nqi ntau dua pem hauv ntej dua li lub twj tso kua dej txheem. Tab sis quav hauv cov tiam ploj los ntawm qhov tsis tau npaj tseg, raug nplua ib puag ncig, kev ua haujlwm kub ntxhov, thiab rov ua dua tshiab - lub neej luv luv ntawm tag nrho lub neej, thiab nws muab tus nqi qis tshaj ntawm cov tswv cuab. Tias yog vim li cas txhua yam tshiab - tsim thiab retrofit FGD qhov project qhia cov twj no rau absorber recirculation, gypsum los ntshav, thiab limestone slurry pub. Nws tsis yog qhov kev xaiv hloov kho tshiab - nws yog lub hauv paus rau kev ua raws cai.
Yog tias koj tab tom ntsuas lub twj tso kua mis rau FGD qhov system, qhov tsis muaj qhov tseem ceeb yog ntws, lub taub hau, slurry hnyav concentration, particle loj tis, thiab pH. Peb lub vev xaib teev cov kev puas tsuaj -cov twj tso kua mis resistant gravel nrog qhov ntau thiab tsawg ntawm 50 hli mus rau 300 hli thiab tshaj. ntub- cov ntaub ntawv kawg yog sib npaug rau koj cov txheej txheem - siab-chrome alloy, roj hmab-lined, thiab silicon carbide kev xaiv yog txhua yam muaj raws li tus qauv qauv. Txhua lub twj tso kua mis tawm lub Hoobkas dynamically balanced thiab hydraulically kuaj. Peb khaws cov khoom tseem ceeb ntawm lub txee thiab tuaj yeem xa khoom sai rau koj qhov chaw ua haujlwm ntawm kev hla - ciam teb logistics. Xa koj cov ntaub ntawv kev khiav hauj lwm rau peb, thiab peb yuav rov qab los nrog kev xaiv uas ua kom lub twj tso kua mis tsis muaj qhov cuam tshuam hauv koj lub voj FGD.
