Raws li qhov yuav tsum tau ua ntawm tus qauv GB18191-2008, * Ntim Cov Thawv: Yas Drums rau Ntim Cov Khoom Phem *, cov dej khib nyiab hauv chav kuaj (xws li cov khib nyiab organic, inorganic acid-cov ntsiab lus, thiab cov ntsiab lus hlau hnyav) yuav tsum muab khaws cia rau hauv 25-liter yas nruas ntim khoom tsim tshwj xeeb zoo. Tag nrho cov ntim ntim rau cov khib nyiab pov tseg yuav tsum muaj daim ntawv pov thawj tshwj xeeb pov tseg pov tseg rau sab nrauv. Cov khib nyiab khib nyiab yuav tsum tau sau npe thiab ua raws li cov cai nruj, thiab muab tso rau hauv qhov chaw khaws cia. Qhov ntim ntawm cov kua khib nyiab ntxiv rau lub nruas yuav tsum tsis pub tshaj 75% ntawm nws cov peev txheej tag nrho. Ib qho funnel yuav tsum tau siv thaum ntxiv cov kua khib nyiab ntau rau hauv lub nruas. Tom qab txhua qhov sib ntxiv ntawm cov kua khib nyiab, lub nruas yuav tsum tau tso cai rau sawv ntsug luv ua ntej lub hau yuav nruj nruj. Thaum lub nruas puv lawm, nws yuav tsum tau xa mus rau qhov chaw cia kom tsis txhob muaj cov kua khib nyiab khaws cia rau hauv lub nruas rau lub sijhawm ntev.

Thaum cov nruas yas zoo tib yam siv los khaws cov kua dej uas muaj hluav taws kub, lawv ua rau muaj kev phom sij ntawm electrostatic. Raws li cov nruas yas zoo tib yam tuaj rau hauv kev sib cuag lossis kev sib txhuam nrog lawv qhov chaw nyob ib puag ncig-tshwj xeeb yog thaum tuav thiab thauj cov nruas txav tau yooj yim- cov nqi hluav taws xob tuaj yeem sib sau rau ntawm lawv qhov chaw sab nrauv. Yog tias qhov nqi hluav taws xob zoo li qub tau nce mus rau theem tseem ceeb, nws yuav ua rau "txhuam tawm," igniting cov nplaim taws vapors tawm ntawm lub nruas qhib thiab ua rau lub teeb tawg. Raws li GB13348-2009, * Kev Nyab Xeeb Kev Nyab Xeeb rau Cov Hluav Taws Xob Hluav Taws Xob ntawm Cov Khoom Siv Roj Hmab *, cov thawv insulating yuav tsum tsis txhob siv rau kev ua haujlwm suav nrog roj av, roj av, lossis cov khoom zoo sib xws; Tsis tas li ntawd, kev siv cov thawv insulating- xws li cov qauv yas nruas (suav nrog cov thawv ntim nruab nrab / IBCs)- khaws cov kua hluav taws xob yog txwv nruj. Los tiv thaiv- cov nruas yas zoo li qub, uas muaj cov tshuaj tiv thaiv- txheej txheej zoo li qub ntawm lawv qhov chaw sab nrauv, yuav raug siv los khaws cov khoom tawg; Txawm li cas los xij, lawv txoj kev siv yuav tsum tau ua raws li cov txheej txheem kev khiav hauj lwm tshwj xeeb- xws li kev txheeb xyuas qhov chaw tiv taus, siv cov hlau hauv av hauv av- yeeb nkab thaum lub sij hawm txhaws, thiab tswj tus nqi filling.
