IG541 inerte gas Vuur Onderdrukking toepas in Metro

Junie 8, 2018

opsomming

Ondergrondse spoorvervoer is 'n nuwe manier van vervoer wat padverkeerdruk verlig.

In brandveiligheid werk, daar is 'n definitiewe bepaling dat daar 'n brandonderdrukkingstelsel moet geïnstalleer word en waar ander brandblustoerusting nodig is.

Vir die keuse van 'n brand onderdrukking stelsel, met inagneming van die besonderhede van ondergrondse spoorvervoer, en omgewingsbeskerming te oorweeg, veiligheid, ekonomie, en brandblusdoeltreffendheid, ons stel voor om die HFC-227ea brandblusstelsel of IG541 Inerte Gas vuur onderdrukking stelsel, Daar is geen skade aan mense nie.

voorwoord

Stedelike ondergrondse spoorweë is 'n belangrike faktorprogram van stedelike konstruksie, dit is die hoof arteries van stedelike vervoer konstruksie.

Die munisipale regering belê baie in ondergrondse spoorwegkonstruksie, en die spoorlyn word normaalweg in die stampvol strook van die stad gebou, verkeer druk te verlig, as oorvol met mense, so daar is 'n sekere risiko van veiligheid ná die spoorlyn is gebou.

The railway/metro operates underground, so if the railway gets into an accident and causes a fire, then it will seriously harm people.

to avoid fire in the underground railways, volgens die bepaling van <-Kode vir Metro Design>, in die spoorweg stelsel die kragopwekker kamer, die enjinkamer, die rekenaarlokaal, en die kragverspreiding toerusting gebied is maklik om te vuur vang.

As the railway is a particular place-underground place when we measure fire suppression, we can not be able to use a water-based fire extinguishing device because water-based is hard to reach, we should use a smart gas fire suppression system, om te verseker dat ons die vuur by sy vroeë stadium te vind en te blus die vuur in tyd, en minimum die verlies.

1. Spoorweg / Metro Station Algemene Situasie

1.1 Metro / Metro Project Oorsig

Take Metro 1 in Beijing as 'n monster, the construction of Metro 1 is normally designed to cross the main road, the setting railway station is normally at the location of the main road or supermarket which continues people’s travel and shopping. Byvoorbeeld, die stasie, and the local supermarket shopping mall, so the metro is very important in the under-ground subway construction, the subway plays an important role in underground transportation in urban, and it is convenient for people’s travel every day and night.

Fire Safety in the subway is serious and important.

1.2 ontwerp Scope

Subway fires not only cause huge damage to railway train equipment but are also harmful to human health. If one day the railway is shut down due to the fire, all train stations will be paralyzed.

2. Ontwerpbeginsels van Metro Vuur Onderdrukking

Subway fire protection design should use an auto fire suppression system and its device, die stelsel moet outomatiese wees, manual control, and mechanical emergency start. Op dieselfde tyd, for the design of the manual control system, we should consider awareness and measurement for the miss-operation manual; the subway should have a different fire supervisor, and every fire zone use a separate totale oorstromings vuur onderdrukking stelsel.

3. Keuse van Vuur Blus Media (Agent)

As the subway is driven by electric power when a fire occurs the water is not able to be used for fire suppression, only a gas fire suppression system is most suitable for the subway fire solutions, but as the subway is underground and crowded with people, so vir keuse van 'n brand blus media / agent moet ons gebruik 'n vinnige vinnige, effektiewe, menslike-veilige gas vuur onderdrukking agent.

3.1 Gas outomatiese vuur onderdrukking stelsel

There is a definite requirement and provision for a gas automatic fire suppression system when fire extinguishing should ensure the subway’s operation is not affected, ensure the subway equipment will not be damaged, and extinguish the fire at its early stage. So an environmentally friendly fire extinguishing agent is an ideal extinguishing media for it, to extinguish the subway fire without air pollution and any hurt to the human body.

3.2 Choose IG41 fire extinguishing agent as extinguishing media in the subway

Met inagneming van die atmosfeer omgewing, die halon 1301 is verbode om as 'n brandblusser gebruik te word aangesien dit besoedeling is; co2 blusmiddel kan brand vinnig blus, maar aangesien die moltreinstasie en treinwa nou is en CO2 skade aan die menslike liggaam sal veroorsaak, so co2 is ook nie voorgestel om te gebruik in die metro; So oorweeg van omgewing, vuur blus doeltreffendheid en Human Veiligheid faktore, gas brand onderdrukking stelsel vir die metro ons kies om te gebruik FM200 vuur onderdrukking stelsel of IG541 brandblusstelsel.

Oorweeg vanuit omgewingsbeskermingsaspek, Die indeks van ODP, GWP, en ALT is 3 belangrike faktore vir omgewingsbeskerming, die fm200-stelsel en inerte gasbrandonderdrukkingstelsel is albei perfek.

IG41 Eienskappe

Oorweeg vanuit Reisveiligheidsaspek, ig541 behoort aan inerte gas en bestaan ​​uit stikstof, argon, en koolstofdioksied, hul proporsie is 52:40, hierdie 3 gasse kom gewoonlik in die atmosfeer voor, so ig541 in die samestelling word as natuurlike skoon gas geneem; die ig541 het die volgende kenmerke:

  1. ODP = 0.
  2. GWP = 0.
  3. Alt = 0.
  4. Behoort aan inerte gas en is nie-korrosief vir elektriese toerusting en fasiliteite.
  5. Dit is deursigtig, kleurlose, reuklose.
  6. Nie-geleidende.
  7. Not have secondary pollution to the atmosphere and not have bad effects for humans.

So the IG541 is very suitable to use in the subway or metro as the main fire extinguishing system.

Considering from Usage Cost Aspect, the FM200 and IG541 Inert Gas fire suppression systems are the ideal fire extinguishing systems for the current subway system.

The cost system consists of product purchase cost, maintenance cost, and transportation cost. For the FM200 system, the product purchase cost is slightly higher, while for the IG541 system, the maintenance cost and transportation costs are slightly higher.

So vergelyking van die twee, the cost them is more or less the same.

4. Afsluiting

After various considerations and implementation results, the IG541 gas fire suppression system is finally the most ideal fire protection system for the subway we choose.

Considering many factors such as economy, omgewingsbeskerming, veiligheid, and efficiency, before establishing a better fire extinguishing system, the IG541 fire extinguishing system should be the most reasonable fire extinguishing system applied in railways or subways.

kleurlose, reuklose, and non-corrosive are the most advantages of subway fire project installation, ingenieurswese, and maintenance.

IG541 gaseous fire extinguishing agent becomes the first choice for the subway.
