Tshem tawm ntawm cov hluav taws kub rov qab thiab siv cov roj ntawm cov roj tua hluav taws
Vim hais tias muaj qee qhov tsim thiab kev tsim kho cov teeb meem hauv cov khoom siv thaum ntxov thiab kev siv ntawm lub boiler, nyob rau lub sij hawm ntev tom qab ntawm lub nkoj, cov ntoo tshauv, hnav thiab tsim kua muag hauv lub rhaub dej thiab qhov sib txawv ntawm cov hluav taws xob zoo ntawm qhov tsim nqi lub ntsiab tseem ceeb uas cuam tshuam lub boiler. Qhov tshwm sim uas ua kom cua sov kub ntawm lub boiler tshaj qhov tsim tus nqi yog thoob plaws, uas tsis yog cia li ncaj qha ua rau lub boiler khiav lag luam. Qhov txo ntawm kev ua haujlwm ua rau cov khib nyiab ntawm lub zog, thiab muaj feem xyuam rau cov hmoov av tshem tawm thiab kev pab cuam ntawm lub plua plav collector, nrog rau kev khiav hauj lwm ntawm kev tsim tawm ntawm desulfurization thiab denitrification system.
Tam sim no, cov kab hluav taws kub thiab cov finned tub thermal hluav taws xob sib txuas yees yog cov teeb meem hauv qab no hauv cov txheej txheem ntawm cov dej khib nyuab rov qab los ntawm cov hluav taws xob hauv lub hwj chim hauv fais fab nroj tsuag:
1. Thaum tshav kub kub ntawm cov khoom siv hluav taws xob kub yog qhov tsawg dua cov kua qaub tshooj ntawm cov dej sulfuric acid, sulfur dioxide thiab sulfur trioxide gas nyob rau hauv cov nkev roj yuav ua rau ntawm phab ntsa ntawm tshav kub hloov hluav taws xob los tsim cov kua qaub (acid) los ua cov cuab yeej hluav taws xob.
2. Tiv thaiv thiab txhaws ntawm cov hmoov tshauv loj hauv cov roj nplaum nplaum: Cov hluav taws kub hloov hluav taws xob tsis tuaj yeem txiav txim siab hloov qhov kev hloov ntawm cov hom ntoo thiab lub thawv dej thiab kho kho cov phab ntsa kub ntawm lub sij hawm nyob rau ntawm lub sijhawm, lub phab ntsa ntawm tshav kub exchanger tom qab dew los sis tsis sib npaug ntawm cov hluav taws xob ntawm cov hluav taws xob sib tshuam los ntawm ib nrab blockage ntawm cov hmoov tshauv. Kev tsim hluav taws xob ua ib feem ntawm cov hluav taws xob ua rau lub cev kub hnyav ua rau sab hauv lub cev kub hnyiab.
Tam sim no, peb lub tuam txhab siv cov khoom siv hluav taws xob hloov los hloov cov khoom siv hluav taws xob tua hluav taws kom tsim thiab tsim cov roj tua hluav taws kub rov qab tsim nrog cov khoom ntiag tug ntawm cov khoom ntiag tug, thiab daws cov teeb meem ntawm qhov ntsuas kub tsawg thiab hnav hauv cov qauv tshiab. Yuav kom paub meej tias phab ntsa qhov kub ntawm qhov kub txav ntawm qhov hluav taws kub khib nyiab kom rov zoo dua qhov qis dua cov kua qaub ntawm cov roj nplaum ntawm 5-15 C. Peb lub tuam txhab kev siv hluav taws xob rov qab los ntawm kev tswj qhov siab tswj thiab paub txog lub hom phiaj ntawm kev kho kom haum cov phab ntsa thiab cov khoom tsis sib haum nrog kev ua haujlwm ntawm qhov chaw ua haujlwm. Txawm tias thaum lub thawm khoom ntawm lub tshuab boiler thiab lub hom roj tuaj yeem hloov cov dej, cov khib nyiab kub rov los ntawm peb lub tuam txhab xyuas kom muaj kev ruaj ntseg thiab ruaj khov ntawm lub tshuab boiler tib lub sij hawm, qhov laj thawj txo qis rau cov pa sov, thiab tsim cov kev pabcuam nyiaj txiag ntau rau lub tuam txhab.
