Ua ntej tshaj plaws, cia' s thawj nkag siab txog kev pov thawj tawg-pov thawj ntawm ob chav thoob ib qhov loj me me ntim cov txheej txheem ntim tshuab: vim hais tias feem ntau ntawm lub tshuab ntim tau ntim nrog hmoov thiab hais, yog li cuam tshuam nrog hmoov av. Qhov kev faib tau yog qhov zoo, tab sis cov hmoov av ntawm ultrafine hmoov (xws li mis hmoov, toner, thiab lwm yam) yog qhov hnyav tshwj xeeb. Lub sijhawm no, vim muaj ntau cov khoom siv plua plav ya mus rau saum huab cua, feem ntau ntawm cov nplaim taws thiab cov plua plav tawg nrog H, C, N, S thiab lwm yam tshuaj lom neeg, thaum lawv nyob hauv cov pa oxidation cov tshuaj tiv thaiv ploj, cua sov yuav tsim cov kev pheej hmoo ntawm kev tawg, tshwj xeeb tshaj yog hmoov txhuas feem ntau yuav tawg rau hauv ib puag ncig ntawm cov pa roj carbon dioxide.
Uas tau hais tias, qhov kev nyuaj ntawm cov khoom plua plav tawg muaj feem xyuam rau qhov xwm ntawm nws tus kheej thiab ib puag ncig. Thiab qhov ua rau tawg yog tsis zoo li qub, qee cov ntaub ntawv yooj yim rau kev siv hluav taws xob, qee cov ntaub ntawv tsis muaj tus cwj pwm tab sis vim tias lub tshuab ua haujlwm thiab kev sib txhuam nrog cua nrog hluav taws xob zoo li qub. Yog li no, nws yog qhov tsim nyog los ua ib qho yooj yim thiab muaj txiaj ntsig los tiv thaiv kev tiv thaiv kev tawg rau lub thawv ntim ob npaug ntawm ib qho loj me me hauv cov txheej txheem ntim tshuab. Nov yog qee qhov qhia me ntsis:
1. Ua kom muaj lub ntsej muag huab cua ruaj khov thiab tsis txhob raug cov roj huab cua. Roj av thiab lwm yam kev kub ntxhov thiab tawg nyob ib puag ncig;
2, kev siv cov chaw nres tsheb muaj plua plav pub dawb thiab lwm txoj kev siv plua plav txhais tau tias kom ntseeg tau qhov ntim ntawm lub tshuab ntim thiab xa cov khoom siv, ua kom tshem tawm cov hmoov av, tuaj yeem zam kev tawg nrog qhov tshwm sim siab;
3, kev siv tawg-pov thawj lub cev muaj zog (flameproof hom, nce kev nyab xeeb hom, hom siab zoo, tsis muaj yam ntxwv tawg thiab hmoov av tawg-pov thawj hom, thiab lwm yam) thiab tawg-pov thawj kov tshuaj ntsuam thiab lwm yam tawg-pov thawj khoom sib dhos tsim ntim tshuab Cov.
