Kuteteza Kuphulika mu Industrial Automation: Kuyika Patsogolo Chitetezo Kuposa Phindu
Kuteteza kuphulika sikungofunika kutsata - ndi mfundo yofunika kwambiri yachitetezo. Pamene opanga makina aku China akukula kukhala mafakitale omwe ali pachiwopsezo chachikulu monga mafuta a petrochemicals, migodi, ndi mphamvu, kumvetsetsa mfundo zoteteza kuphulika kumakhala kofunika kuti pakhale mpikisano wapadziko lonse lapansi komanso chitetezo pantchito.
The Science Behind Industrial Explosions
Kuphulika kumafuna zinthu zitatu zofunika:
- Zinthu Zophulika- Mipweya (hydrogen, methane), zakumwa (mowa, mafuta), kapena fumbi (shuga, chitsulo, ufa)
- Oxidizer- Nthawi zambiri mpweya umapezeka mumlengalenga
- Gwero lamoto- Kuwala, malo otentha, kutulutsa kosasunthika, kapena kusintha kwamankhwala
Mfundo yofunika kwambiri yopewera kuphulika ikuphatikizapo kuchotsa chimodzi mwa zinthu zitatuzi.
Kumvetsetsa Zida Zowonetsera Kuphulika: "Ex ed IIC T6"
Chizindikiro chodziwika bwino pazida zosaphulika chikuwonetsa:
- Ex: Kutsata miyezo yoteteza kuphulika
- e: Kuchulukitsa kwachitetezo
- d: Malo otetezedwa ndi moto
- IIC: Oyenera mpweya wowopsa kwambiri (hydrogen, acetylene)
- T6: Kutentha kwakukulu kwa pamwamba ≤85 ° C (otetezeka pazinthu zomwe zili ndi malo otsika oyatsira)
Njira Zotetezera Kuphulika Kwambiri
Malo Otetezedwa ndi Moto (Ex d)
Zopangidwa mwapadera kuti zikhale ndi zophulika zamkati ndikuletsa kuyatsa kwamlengalenga wowopsa wakunja.
Intrinsic Safety (Ex i)
Imachepetsa mphamvu zamagetsi kuti zifike pansi pa zomwe zikufunika kuti ziwotche, ngakhale pakagwa vuto. Imafunika zolepheretsa kudzipatula kuti mukhale otetezeka mu dongosolo lonse.
Magawo Owopsa: Magawo, Magulu a Gasi & Magawo a Kutentha
Zone Classification (Miyezo ya IEC)
- Zone 0: Kukhalapo kosalekeza kwa mpweya wophulika
- Zone 1: Kuthekera kukhalapo panthawi yogwira ntchito bwino
- Zone 2: Kukhalapo kwakanthawi kapena kwakanthawi kophulika
Gasi Gulu Gulu
- IIA: Mipweya yowopsa (propane)
- IIB: Mipweya yowopsa yapakatikati (ethylene)
- IIC: Mipweya yowopsa kwambiri (acetylene, haidrojeni)
Kutentha Mavoti
| T-Class | Kutentha Kwambiri Pamwamba |
|---|---|
| T1 | ≤450°C |
| T6 | ≤85°C |
Ngozi Zambiri: Maphunziro pa Chitetezo
- BP Texas City (2005): Anthu 15 afa chifukwa choyatsa nthunzi wa hydrocarbon
- Buncefield, UK (2005): Kuphulika kwakukulu kwa mpweya chifukwa cha kudzaza kwa thanki
- Imperial Sugar, USA (2008): Fumbi laphulika lapha anthu 14 chifukwa chosasamalira bwino m’nyumba
Zowopsazi zikugogomezera kufunikira kofunikira kwa machitidwe ovomerezeka otetezedwa kuphulika kwa madera.
Kusankha Zida Zodzitchinjiriza Zotetezedwa: Zofunika Kwambiri
Posankha njira zodzipangira zokha m'malo owopsa, onetsetsani:
- Kodi zidazo zikufanana ndi zomwe mukufuna komanso gulu la gasi?
- Kodi kalasi ya kutentha ndiyoyenera pulogalamu yanu?
- Kodi zigawo zonse zili m'gulu lovomerezeka loletsa kuphulika?
Osanyengererapamiyezo yoteteza kuphulika. Chitetezo chiyenera kukhala chomwe chimapangitsa kuti munthu asankhe zochita—chifukwa zomwe zili pachiwopsezo zimapitilira kuwononga ndalama m'miyoyo ya anthu.
Lumikizanani ndi Akatswiri Athu Oteteza Kuphulika
Pamayankho otsimikizika ogwirizana ndi zomwe mukukumana nazo zowopsa za chilengedwe
