Ⅰ. Umgaqo

I-SO2 yenye yezona zinto zingcolisa umoya kunye nesalathiso esibalulekileyo solawulo longcoliseko lwegesi yenkunkuma eChina. Okwangoku, zonke iiyunithi zoomatshini bamalahle e-China baphumeze iiprojekthi ze-flue gas desulfurization, phakathi kwayo itekhnoloji ebalaseleyo ye-desulfurization yi-limestone/gypsum wet flue gas desulfurization (WFGD). Kule nkqubo, i-limestone slurry isetyenziswa njenge-absorbent, ehambelana ne-countercurrent kunye ne-flue gas kwi-desulfurization tower kwaye ixutywe ngokupheleleyo. Emva kokuba i-SO2 kwi-flue gas isabela kunye ne-absorbent, i-chemically isabela ngomoya we-oxidizing ovuthelwa yi-fan oxidizing ukwenza i-gypsum.

Kukho itanki ye-slurry ezantsi kwinqaba yokufunxa, kwaye i-absorbent entsha iphonswa kwitanki ye-slurry ngokusebenzisa i-limestone feeding slurry pump; phantsi komsebenzi we-agitator, ixutywe kunye ne-slurry ekhoyo kwi-tank ye-slurry; ke, impompo ejikelezayo enodaka iya kuphakamisa udaka oluxubeneyo ukuya kumaleko wokutshiza kwaye itshize phantsi ukuze idibane nerhasi ye-flue kwi-counter-current flow. Ukuzaliswa ngokufanelekileyo nangexesha kwe-absorbent entsha kubalulekile kuyo yonke inkqubo. Ukuba isixa esongezelelweyo asanelanga, kunzima ukuqinisekisa ukusebenza kakuhle kwe-desulfurization; ukuba isixa esongezelelweyo siphezulu kakhulu, siya kunciphisa izinga lokusetyenziswa kwe-absorbent, kwaye ichaphazele umgangatho we-desulfurization by-products. Ke ngoko, ulawulo lwempompo ye-limestone slurry luyinxalenye ebalulekileyo yokusebenza kwe-FGD.

Ⅱ. Iimpompo ezifunwa yinkqubo yokucubungula

1. Inkqubo yokulungiselela ilitye likakalika

2. Impompo yenkqubo yenqaba yokufunxa

3. Inkqubo yegesi yomkhuhlane

4. Impompo ye-gypsum dewatering system

5. Iimpompo zeenkqubo zokukhupha

6. Iimpompo zeenkqubo zokucocwa kwamanzi amdaka

Ngaphandle kwenkqubo yegesi ye-flue, ezi nkqubo zingasentla ziya kufuna zonke iimpompo ezinodaka. Kwinkqubo yetower yokufunxa, umthamo wenaliti mkhulu kakhulu, ngoko ke ububanzi bempompo bukhulu kakhulu. Iimpompo ezikule nxalenye ziyiempompo ezikhethekileyo ezinkulu ezenzelwe i-desulfurization, kwaye iimpompo ezisetyenziswa kwezinye iinkqubo zisetyenziswa ngokuqhelekileyo iimpompo ze-slurry ezincinci kunye neziphakathi. Ngokwemeko ye-slurry, izinto ezikhethiweyo zamacandelo okuhamba zimbini zinxiba-resistant kunye ne-corrosion-resistant.

Isiketshi seNkqubo yeFGD

Impompo ejikelezayo yenkqubo ye-FGD esetyenziswa kwiSiza
