Ilaalinta Qaraxa Automation-ka Warshadaha: Ka Hormarinta Badbaadada Faa'iidada
Ilaalinta qaraxyadu kaliya maahan shuruud u hoggaansan - waa mabda'a badbaadada aasaasiga ah. Sida soosaarayaasha shiinaha ee otomaatiga u balaariyaan warshadaha khatarta sare leh sida petrochemicals, macdanta, iyo tamarta, fahamka heerarka ilaalinta qaraxa ayaa muhiim u ah tartanka caalamiga ah iyo badbaadada hawlgalka labadaba.
Sayniska ka dambeeya Qaraxyada Warshadaha
Qaraxu wuxuu u baahan yahay saddex walxood oo muhiim ah:
- Walxaha qarxa- Gaasaska (hydrogen, methane), dareerayaasha (khamriga, shidaalka), ama boodhka (sonkorta, birta, burka)
- Oxidizer- Caadi ahaan ogsijiinta hawada ku jirta
- Isha dabka- Dhimbiilyo, oog kulul, dareere taagan, ama falcelin kiimikaad
Mabda'a aasaasiga ah ee ka-hortagga qaraxa waxay ku lug leedahay baabi'inta mid ka mid ah saddexdan arrimood.
Fahamka Calaamadaynta Qalabka Caddeynta Qarax: "Ex ed IIC T6"
Calaamaddan caadiga ah ee qalabka aan qarxin waxay muujineysaa:
- ExU hoggaansanaanta heerarka ilaalinta qaraxa
- eNakhshad badbaado oo kordhay
- d: Xero ololaysa
- IIC: Ku habboon gaaska khatarta sare leh (hydrogen, acetylene)
- T6Heerkulka dusha sare ee ugu badan ≤85°C
Hababka Ilaalinta Qaraxa Koowaad
Daboolka aan ololka lahayn (Ex d)
Si gaar ah loogu talagalay in lagu xakameeyo qaraxyada gudaha iyo ka hortagga shidda jawiga khatarta ah ee dibadda.
Badbaadada Gudaha (Ex i)
Waxay ku xaddidaysaa tamarta korantada heerar ka hooseeya waxa loo baahan yahay si loo shido, xitaa marka lagu jiro xaaladaha cilladda. Waxay u baahan tahay carqalado go'doomin ah si loo ilaaliyo badbaadada nidaamka oo dhan.
Kala-soocidda Aaga Khatarta leh: Aagagga, Kooxaha Gaaska & Qiimaynta Heerkulka
Kala-soocidda Aagga (Heerarka IEC)
- Aagga 0Joogitaanka joogtada ah ee jawiga qarxa
- Aaga 1: Waxay u badan tahay joogitaanka inta lagu jiro hawlgallada caadiga ah
- Aaga 2Naadirka ama joogitaanka kooban ee jawiga qarxa
Kala saaridda Kooxda Gaaska
- IIA: Gaasaska halista ah (propane)
- IIB: Gaasaska khatarta ah ee dhexdhexaadka ah (ethylene)
- IICGaasaska khatarta sare leh (acetylene, hydrogen)
Qiimaynta Heerkulka
| T-Class | Heerkulka Dusha ugu sarreeya |
|---|---|
| T1 | ≤450°C |
| T6 | ≤85°C |
Shilalka Taariikhiga ah: Casharrada Badbaadada
- BP Texas City (2005): 15 dhimasho ah oo ay sababtay shidista uumiga hydrocarbon
- Buncefield, UK (2005): Qarax weyn oo hawo shidaal ah oo ka dhashay haamo buux dhaafiyay
- Sonkorta Imperial, USA (2008): Qarax boodh ah oo galaaftay nolosha 14 qof, taas oo ay ugu wacan tahay ilaalinta guriga oo aan ku filnayn
Masiibooyinkani waxay hoosta ka xariiqeen muhiimadda muhiimka ah ee nidaamyada ilaalinta qaraxa ee shahaadaysan, aagga ku habboon.
Doorashada Qalabka Automation Safe: Tixgelinta Muhiimka ah
Markaad dooranayso xalalka otomaatiga ah ee deegaanka khatarta ah, had iyo jeer xaqiiji:
- Qalabku ma ku habboon yahay aaggaaga gaarka ah iyo shuruudaha kooxda gaaska?
- Heerka heerkulku ma ku habboon yahay codsigaaga?
- Dhammaan qaybaha ma yihiin qayb ka mid ah nidaamka caddaynta qaraxa?
Weligaa ha tanaasulinon heerarka ilaalinta qaraxa. Nabadgelyadu waa inay noqotaa xoogga ka dambeeya go'aannada naqshadaynta-maxaa yeelay waxa la isku hayo ayaa aad uga fog maalgelinta maaliyadeed ee nolosha aadanaha.
