Wat is de effectieve bewaking bereik van waterstof gas detector?
Waterstof alarm is wijdverbreid gebruikt in aardolie, chemische industrie, metallurgie, ruimtevaart, licht industrie en andere gebieden. As a veiligheid apparaat, waterstof detector kan een rol in detectie en vroegtijdige waarschuwing alleen als het is correct geïnstalleerd en redelijk. Volgens de relevante nationale normen, de detectie diameter van waterstof brandbaar gas alarm in slecht geventileerde plaatsen moeten zijn minder dan 5 meter, en de detectie diameter van waterstof detector in open plaatsen moeten zijn 10 meter.
Hydrogen is a kind of high-quality energy, which is widely used in all walks of life. In agriculture, it can improve seed germination rate, regulate flowering period, improve stress resistance, improve pest resistance, improve agricultural products quality, and keep products fresh. In the chemical field, it is one of the raw materials for synthetic ammonia and methanol processes; It can be used in petroleum desulfurization, refining and catalytic cracking in oil refining. Electronic industry can be used as protective gas, and metallurgical industry can be used as protective gas and reducing agent. The combustion heat value of hydrogen is very high, and it will not produce harmful substances. As a clean energy, it has a very good application in the aerospace field. In recent years, hydrogen has also developed rapidly in the fields of beauty and medicine.
Although hydrogen will not cause poisoning, it is very easy to burn and explode, causing fire and other dangers. It is very important to use the hydrogen alarm reasonably and correctly. According to GBT{{0}}, the horizontal distance between hydrogen detectors installed in closed factory buildings or places with poor local ventilation and any release source within its coverage should not be more than 5m; The horizontal distance between the hydrogen detector in an open or open workshop and any release source within its coverage should not be more than 10m, and the hydrogen detector should also be installed at the position where hydrogen is easy to accumulate at the highest point of the workshop. In addition, the installation height of the hydrogen alarm is also required. Because the specific gravity of hydrogen and air is much less than 0.8 and lighter than air, the hydrogen alarm should be installed within 2.0m above the release source, and there should be no impact, vibration, strong electromagnetic interference and easy maintenance.
De bovenstaande is een inleiding aan de effectieve bewaking bereik van de waterstof gas detector. Waterstof is gebruikt in alle wandelingen van leven, maar omdat het zal branden en ontploffen, het is noodzakelijk om een waterstof waterstof brandbaar gas alarm bij de mogelijke lekkage positie om de concentratie verandering van waterstof te detecteren. de explosie bereik van waterstof is 4.0%-75.6%, en de explosie Bereik is zeer breed, dus het gebruik van waterstof detector is bijzonder belangrijk. Het kan de concentratie van waterstof en effectief ongevallen voorkomen zoals branden veroorzaakt door waterstof lekkage.
