thauj khoom tsis tu ncua thaum ua haujlwm ruaj khov kom txog thaum ua haujlwm puv.
7. Kaw-down
(1) Kev kaw hluav taws xob kub ceev (roj) khoom.
Kaw inlet thiab qhov hluav taws xob li qub.Khaws qhov kub thiab txias.Yog tias tsim nyog, siv nitrogen lossis hydrogen-nitrogen
gas kom tswj lub siab kom tiv thaiv tsis zoo siab.
(2) Hloov-dhau ntawm desulfurization adsorbent
Kaw inlet thiab qhov hluav taws xob li qub.Tsis tu ncua txo qhov kub thiab txias rau ambient mob.Ces cais cov
desulfurization reactor los ntawm cov txheej txheem ntau lawm.Hloov cov reactor nrog cua kom txog thaum cov pa oxygen concentration> 20% tau txais.Qhib lub reactor thiab unload lub adsorbent.
(3) Cov cuab yeej tu (overhaul)
Ua tib zoo saib cov txheej txheem raws li qhia saum toj no tshwj tsis yog tias lub siab yuav tsum qis dua 0.5MPa / 10min thiab temp.
txo qis lawm.
Lub unloaded adsorbent yuav tsum muab cia rau hauv nyias txheej.Txheeb xyuas cov qauv coj los ntawm txhua txheej los txiav txim
raws li txoj cai thiab kev pab lub neej ntawm lub adsorbent.
8.Kev thauj mus los thiab khaws cia
(1) Cov khoom adsorbent tau ntim rau hauv cov yas los yog hlau phom nrog cov yas hauv ob sab phlu kom tsis txhob ya raws thiab tshuaj
kev kis kab mob.
(2) Kev sib tsoo, kev sib tsoo thiab kev vibration hnyav yuav tsum tau zam thaum lub sijhawm thauj mus los los tiv thaiv pulverization ntawm
adsorbent.
(3) Cov khoom adsorbent yuav tsum raug tiv thaiv los ntawm kev sib cuag nrog cov tshuaj thaum thauj thiab khaws cia.
(4) Cov khoom tuaj yeem khaws cia rau 3-5 xyoos yam tsis muaj kev puas tsuaj ntawm nws cov khoom yog tias tsim nyog kaw.
