Combustible Dust Explosion Analysis

Qhov xwm txheej:

Lub yim hli ntuj 2, 2014, txhuas hmoov tawg ntawm Kunshan Zhongrong Hlau Khoom Tuam Txhab coj mus rau ib tug tragic xov tooj ntawm 75 neeg tuag thiab 185 raug mob, kos ib zaj lus qhia tob thiab kim heev. Thoob plaws hauv keeb kwm thiab thoob plaws ntiaj teb, hmoov av tawg xwm txheej tau tshwm sim. Niaj hnub no, nrog lub nrawm nrawm ntawm industrialization, qhov tshwm sim ntawm combustible plua plav explosions yog nce.

Hom Plua plav Combustible:

Pawg no suav nrog ntau yam khoom siv xws li txhuas, magnesium, zinc, ntoo, hmoov, qab zib, textile fibers, roj hmab, yas, ntawv, thee, thiab luam yeeb hmoov av. Cov ntaub ntawv no feem ntau muaj nyob rau hauv metalworking, ua ntoo, kev ua zaub mov, thiab plastics manufacturing industries.

Defining Combustible Plua plav:

Combustible plua plav muaj cov khoom zoo uas, thaum ncav cuag tej huab cua concentration, muaj kev cuam tshuam rau igniting thiab ua rau hluav taws kub los yog tawg. Ib qho loj ntawm cov plua plav ntsib qhov chaw tshav kub xws li nplaim taws lossis qhov kub thiab txias hauv qhov chaw uas nyob ib puag ncig tuaj yeem ua rau lub hauv paus thiab tom qab tawg.. Cov explosions no disperse burning hais thiab tsim copious toxic gases, ua rau raug mob hnyav thiab tuag taus.

Cov tswv yim tiv thaiv:

Kev txo cov plua plav tawg yuav tsum muaj kev qhia dav dav uas suav nrog kev teeb tsa kev cob qhia, tswj plua plav, tiv thaiv hluav taws, waterproofing, thiab cov txheej txheem nruj.

Rhiav kev cai:

Cov cheeb tsam uas muaj plua plav tawg yuav tsum tsis txhob nyob hauv thaj chaw nyob thiab yuav tsum tswj kom muaj kev sib cais los ntawm lwm cov qauv kom muaj kev nyab xeeb ntawm hluav taws..

Hluav taws kub thiab plua plav tswj:

Kev cob qhia yuav tsum tau muab tso rau raws li cov qauv txheej txheem nrog kev ua pa zoo, plua plav systems, thiab hauv av mechanisms. Cov plua plav collectors yuav tsum tau muab tso rau sab nraud nrog kev tiv thaiv los nag. Cov plua plav uas tau sau tseg yuav tsum muab khaws cia rau hauv kev sib cais, qhuav qhov chaw. Kev tu vaj tse hauv thaj chaw tsim khoom yuav tsum tiv thaiv kom tsis txhob muaj teeb meem, static tsim, thiab plua plav dispersal.

Kev tiv thaiv:

Cov chaw muaj kev pheej hmoo ntawm cov plua plav tawg yuav tsum tau nruab nrog cov khoom siv tiv thaiv hluav taws xob zoo li qub. Nws yog ib qho tseem ceeb kom ua raws li cov cai ntawm kev teeb tsa thiab kev siv Cov khoom siv hluav taws xob tawg.

Kev ntsuas dej tsis zoo:

Cov chaw tsim khoom xav tau waterproof thiab damp-proof installations tiv thaiv plua plav los ntawm nws tus kheej-igniting thaum moist.

Txheej txheem txheej txheem:

Ua kom muaj kev nyab xeeb yog ua raws li cov txheej txheem ua haujlwm nruj, xav kom txhua tus neeg ua haujlwm hnav cov khoom tiv thaiv tsim nyog, siv cov tshuaj tiv thaiv zoo li qub, thiab muaj kev nkag mus rau cov khoom siv tua hluav taws. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia txog kev nyab xeeb ua ntej ua lawv txoj haujlwm. Kev kawm txog kev nyab xeeb tsis tu ncua thiab kev cob qhia rau txhua tus neeg ua haujlwm yog qhov tseem ceeb kom nkag siab tag nrho cov kev phom sij cuam tshuam nrog tawg hmoov av thiab kev ceev faj tsim nyog.
