Ⅰ. Txoj Cai
SO2 yog ib qho ntawm cov pa phem hauv huab cua thiab ib qho tseem ceeb tswj qhov taw qhia ntawm kev lag luam khib nyiab roj hauv Suav teb. Tam sim no, txhua lub tshuab hluav taws xob hluav taws xob hauv Suav teb tau siv cov roj hluav taws xob desulfurization, cov uas tseem ceeb desulfurization tshuab yog limestone / gypsum ntub flue gas desulfurization (WFGD). Nyob rau hauv cov txheej txheem no, limestone slurry yog siv los ua ib tug absorbent, uas yog nyob rau hauv countercurrent sib cuag nrog cov flue roj nyob rau hauv lub desulfurization ntauwd thiab ces yog tag nrho tov. Tom qab SO2 nyob rau hauv cov roj flue reacts nrog lub absorbent, nws chemically reacts nrog oxidizing cua uas yog tshuab los ntawm oxidizing kiv cua los tsim gypsum.
Muaj lub tank slurry nyob rau hauv qab ntawm tus neeg siv ntauwd, thiab cov khoom nqus dej tshiab tau muab tso rau hauv lub tank slurry los ntawm limestone pub slurry twj tso kua mis; nyob rau hauv kev ua haujlwm ntawm agitator, nws yog tov nrog cov slurry uas twb muaj lawm nyob rau hauv lub slurry tank; Tom qab ntawd, lub slurry circulating twj tso kua mis yuav tsa cov slurry sib xyaw rau hauv cov txheej txheem tshuaj tsuag thiab tshuaj tsuag nws mus rau kev sib cuag nrog cov roj flue hauv counter-tam sim no ntws. Kev ua tau zoo thiab raws sij hawm ntxiv ntawm cov khoom nqus dej tshiab yog qhov tseem ceeb thoob plaws hauv tag nrho cov txheej txheem. Yog tias cov nyiaj ntxiv tsis txaus, nws yog qhov nyuaj los lav qhov kev ua haujlwm desulfurization; Yog hais tias tus nqi ntxiv yog siab dhau, nws yuav txo qhov kev siv ntawm cov khoom nqus, thiab cuam tshuam rau qhov zoo ntawm desulfurization by-products. Yog li, limestone slurry twj tswj yog ib feem tseem ceeb ntawm FGD kev ua haujlwm.
Ⅱ. Pumps xav tau los ntawm kev ua haujlwm
1. Limestone npaj system
2. Lub twj tso kua mis rau lub tshuab nqus tsev ntauwd
3. Flue gas system
4. Pump rau gypsum dewatering system
5. Cov twj tso kua mis tso tawm
6. Cov twj tso kua mis rau kev kho cov dej khib nyiab
Tsuas yog lub tshuab hluav taws xob flue, cov tshuab saum toj no yuav tsum muaj cov twj slurry. Nyob rau hauv lub tshuab nqus tsev ntauwd, qhov kev txhaj tshuaj yog qhov loj, yog li txoj kab uas hla ntawm lub twj tso kua mis kuj loj. Cov twj tso kua mis hauv qhov no yog cov twj loj loj tshwj xeeb tsim rau desulfurization, thiab cov twj siv hauv lwm lub tshuab yog peb cov twj siv me me thiab nruab nrab slurry twj. Raws li qhov xwm txheej ntawm slurry, cov khoom xaiv ntawm cov khoom ntws yog ob qho tib si hnav-resistant thiab corrosion-resistant.
