Nta ntawm petrochemical hluav taws kub xwm txheej
Dec 10, 2022
1. Qhov kev pheej hmoo tawg yog loj. Ua ntej tshaj plaws, cov khoom siv thiab cov kav dej ntawm cov khoom siv petrochemical thiab cov chaw cia khoom khaws cia ntau cov khoom siv hluav taws xob los yog cov khoom lag luam, thiab nws yooj yim los tsim lub cev tawg tom qab tawg tawg lossis nthuav tawm tom qab cua sov; Qhov thib ob, qhov siab ntawm kev txuas ntxiv ntawm cov khoom siv ntau lawm, uas yog ib qho yooj yim los tsim kev tawg tas li; Hauv cov txheej txheem kev tua hluav taws tsis raug, ntau qhov tawg tuaj yeem tshwm sim.
2. Qhov hluav taws kub tau loj hlob sai. Raws li kev suav ntawm kev sib ntaus sib tua hluav taws, thaum hluav taws tshwm sim hauv kev lag luam petrochemical, qhov sib kis ceev ntawm cov nplaim hluav taws tuaj yeem ncav cuag 2 ~ 3 m / s. Nyob rau tib lub sijhawm, nws cov combustion tus nqi kuj ceev heev, piv txwv li: roj av hluav taws xob tuaj yeem ncav cuag 80.9 kg / m² * h, benzene tuaj yeem ncav cuag 165.4kg / m² * hr. Qhov ceev ntawm hlawv thiab tawg yog tsis yooj yim sua kom tiv thaiv.
3. Nws yog ib qho yooj yim los tsim peb-dimensional loj-chaw combustion. Thaum hluav taws tshwm sim hauv ib lub tsev lossis cov qauv uas tsim thiab khaws cov khoom siv hluav taws xob thiab cov khoom tawg, vim muaj kev cuam tshuam kev cuam tshuam ntawm cov tsev thiab cov qauv, nws yog ib qho yooj yim uas yuav ua rau peb-dimensional combustion los ntawm hluav taws; Hauv qhov hluav taws kub, cov pa roj uas muaj qhov hnyav dua li huab cua kis tau los ntawm sab saum toj mus rau hauv qab, thiab peb-seem combustion yuav raug tsim thaum ntsib qhov hluav taws kub; Flammable thiab explosive kua yog cuam tshuam los ntawm kub los yog kub hluav taws xob, thiab volatile vapor yuav ntab thiab kis tau los ntawm qab mus rau sab saum toj nrog cua, thiab nws yog ib qho yooj yim rau tsim peb-dimensional combustion tshwm sim thaum lub qhov hluav taws kub ntws los yog splashes hluav taws.
4. Nws yog ib qho yooj yim rau re-ignite thiab re-detonate. Nyob rau hauv petrochemical hluav taws, tom qab cov roj los yog roj hluav taws tua, yog hais tias nws yog tsis zoo muab pov tseg nyob rau hauv lub sij hawm, cov residue tseem yuav hlawv los yog tawg dua, uas yuav tsum tau them nyiaj mloog zoo rau hauv kev sib ntaus sib tua hluav taws.
5. Kev puas tsuaj loj heev. Petrochemical hluav taws kub muaj qhov kub ceev ceev, siab calorific nqi, thiab muaj zog thermal tawg nyob rau hauv qhov chaw tua hluav taws, uas yog ib qho yooj yim ua rau raug mob rau cov neeg cawm siav. Tsis tas li ntawd, qhov to thiab diffusion ntawm cov tshuaj lom thiab cov txaws thiab ntws ntawm cov khoom siv hluav taws xob thiab cov khoom tawg ua rau thaj chaw loj, peb sab lossis ntau qhov hluav taws kub, uas nthuav tawm thiab ua rau muaj kev kub ntxhov thiab kev puas tsuaj, thiab nws cov tshuaj lom. gas kuj yooj yim ua rau raug mob rau cov neeg cawm siav.
