Thaum lub sij hawm sulfuric acid ntau lawm, ib tug loj npaum li cas ntawm thermal zog yog generated thaum sulfur combustion thiab sulfur dioxide conversion. Yuav ua li cas cov cua sov no rov qab tau thiab hloov mus rau hauv lub zog siv tau?
Pov tseg tshav kub rov qab yog ib feem tseem ceeb ntawm sulfuric acid tsim system tsim. Es tsis txhob tso siab - kub txheej txheem cua sov ncaj qha, lub kaw lus siv boilers, tshav kub exchangers, thiab cov khoom tsim hluav taws xob hloov hluav taws xob thermal rau hauv chav siv tau. Lub zog rov qab los no tuaj yeem txhawb nqa cov khoom siv cog qoob loo, txo cov kev xav tau ntawm lub zog sab nraud, thiab txhim kho cov txheej txheem tag nrho.
Lub tshuab hluav taws xob tsim hluav taws xob kom zoo yuav tsum muaj kev sib koom tes ntawm kev tswj qhov kub thiab txias, roj cua txias, chav tsim hluav taws xob, thiab cov txheej txheem siv hluav taws xob. Kev xaiv cov khoom siv rov qab, kev ua haujlwm tsis zoo, thiab kev sib koom ua ke ncaj qha cuam tshuam rau kev ruaj ntseg ntawm cov txheej txheem ntau lawm.
Nkag siab txog Kev Siv Hluav Taws Xob Hluav Taws Xob Hauv Kev Tsim Khoom Siv Sulfuric Acid
Cov txheej txheem tsim cov sulfuric acid suav nrog ntau qhov siab - qhov kub thiab txias. Thawj qhov cua kub tseem ceeb yog los ntawm kev sib txuas ntawm sulfur.
Cov kua sulfur yog txau rau hauv lub qhov cub sulfur thiab reacts nrog cua qhuav kom tsim sulfur dioxide (SO₂). Cov tshuaj tiv thaiv combustion no ua rau siab -kub roj, nrog rau qhov hluav taws kub qhov hluav taws xob feem ntau ncav cuag 1000℃.
Es tsis txhob cia cov cua sov no ploj mus, cov roj tau dhau los ntawm cov khoom siv hluav taws xob pov tseg. Lub boiler hloov cov cua sov los ntawm cov txheej txheem roj mus rau dej, ua kom muaj zog thaum txo cov roj kub ua ntej nkag mus rau hauv seem hloov dua siab tshiab.
Qhov thib ob qhov cua sov yog los ntawm kev hloov pauv catalytic. Thaum lub sij hawm oxidation ntawm SO₂ rau hauv sulfur trioxide (SO₃), cov tshuaj tiv thaiv tso tawm cua sov ntxiv. Thaum tshav kub kub exchangers thiab economizers yog siv nyob rau hauv txawv theem hloov dua siab tshiab los tswj roj kub thiab rov qab thermal zog.
Ib qho kev ua kom rov qab los ua kom sov ib txwm muaj xws li:
Cov khoom no ua haujlwm ua ke kom rov qab tau cov cua sov los ntawm cov txheej txheem sib txawv thiab muab chav rau cov nroj tsuag ua haujlwm.
Cov txheej txheem tseem ceeb ntawm khib nyiab thaum tshav kub kub rov qab
1. High-Tub kub Gas Generation
Cov txheej txheem pib nrog sulfur combustion.
Molten sulfur nkag mus rau hauv lub qhov cub sulfur thiab reacts nrog oxygen los ntawm huab cua qhuav:
Cov tshuaj tiv thaiv ua rau lub siab -kub roj av uas muaj SO₂. Qhov kub ntawm cov roj combustion yuav tsum raug txo kom tsawg ua ntej nkag mus rau lub catalytic converter vim hais tias cov catalyst yuav tsum tau tswj kev khiav hauj lwm tej yam kev mob.
2. Thaum tshav kub kub hloov los ntawm khib nyiab kub boiler
Qhov siab -kub SO₂ roj nkag mus rau hauv cov khib nyiab kub boiler.
Nyob rau hauv lub boiler, tshav kub hloov ntawm lub gas sab mus rau sab dej. Qhov kub ntawm cov txheej txheem roj txo qis, thaum dej absorbs thermal zog thiab ua chav.
Hauv kev lag luam sulfuric acid tej yaam num, khib nyiab boilers yog tsim raws li:
- Gas kub

- Sab nraud steam networks
Hauv qee qhov haujlwm, cov khoom siv rov qab los ua ib feem ntawm kev tswj hwm lub zog tag nrho ntawm cov chaw siv tshuaj.
4. Thaum tshav kub kub hloov dua siab tshiab
Tom qab combustion tshav kub rov qab, cov roj SO₂ nkag mus rau lub converter.
Cov tshuaj tiv thaiv catalytic:
tso tawm thermal zog ntxiv.
Thaum tshav kub kub exchangers yog ntsia nruab nrab ntawm cov theem catalytic los tswj cov tshuaj tiv thaiv kub thiab rov qab cua sov.
Lub zog rov qab tuaj yeem siv rau:
- Kho qhov kub thiab txias tuaj
- Txhim kho thermal tshuav nyiaj li cas
- Txhawb nqa chav ntau lawm
Kev sib xyaw ua ke ntawm combustion heat recovery thiab conversion heat recovery txhim kho lub zog siv ntawm tag nrho cov txheej txheem ntau lawm.
Cov yam tseem ceeb cuam tshuam rau cov khib nyiab cua sov rov qab qhov system tsim
Txheej txheem kub tswj
Kev tswj qhov kub thiab txias yog qhov tseem ceeb vim tias ob qho tib si combustion thiab catalytic hloov dua siab tshiab yuav tsum tau ua haujlwm tshwj xeeb.
Yog tias cov roj kub kub siab dhau lawm, cov cuab yeej siv zog yuav nce ntxiv. Yog tias qhov kub thiab txias qis dhau, cov tshuaj tiv thaiv catalytic yuav txo qis.
Cov txheej txheem rov qab yuav tsum sib npaug kom tshem tawm cov cua sov thiab cov txheej txheem yuav tsum tau ua.
Chav yuav tsum
Cov haujlwm sib txawv muaj qhov sib txawv ntawm qhov xav tau.
Thaum lub sij hawm tsim engineering, cov neeg muag khoom yuav tsum ntsuas:

Cov Khoom Siv Khoom Xaiv
High -kub roj thiab acidic tej yam kev mob tsim teeb meem rau cov khoom siv.
Tus tsim yuav tsum xav txog:
- Ua haujlwm kub
- Gas muaj pes tsawg leeg
- Corrosion tej yam kev mob
- Mechanical stress
Kev xaiv cov khoom tsim nyog pab tswj cov cuab yeej kev ntseeg siab thaum ua haujlwm tas mus li.
Kev sib koom ua ke
Cov khib nyiab rov qab tsis yog ib qho kev ywj pheej. Nws yuav tsum tau ua ke nrog:
- Sulfur combustion system
- Kev hloov pauv seem
- Thaum tshav kub kub exchanger network
- Chav kaw lus
