Gas extinguishing

The culprit of the global greenhouse effect is carbon dioxide, mainly due to the burning of coal, natural gas and natural gas in modern industrial society, the amount of carbon dioxide gas contained in the emissions is caused by the atmosphere.

However, in the natural gas fire industry began to apply gas fire is carbon dioxide gas fire extinguishing, because of the fire characteristics of carbon dioxide gas, fire efficiency, as well as the production of simple, low cost factors of gas fire industry is widely used, when a fire occurs, carbon dioxide gas from the storage container quickly ejected to put out the fire. When the fire dies down, the carbon dioxide gas remains permanently in the air, increasing the concentration of some carbon dioxide in the air.

According to relevant statistics

In April 2014, the average monthly carbon dioxide concentration in the northern Hemisphere exceeded 400 ppm (ppm).

This phenomenon can be seen as another warning that greenhouse gas emissions are rising and that urgent action must be taken to control new greenhouse gas emissions.

Since the Arctic, radio records in Canada, the United States, Norway and Finland indicate an average monthly CO2 concentration of 400 ppm in the lower northern latitudes in the spring since 2012.

The World Meteorological Organization's observatories in Cape Verde, Germany, Ireland, Japan, Spain and Switzerland reported that the monthly average concentration of carbon dioxide exceeded 400 parts per million in March and April 2012.

In April 2014, all stations in the Northern Hemisphere, part of the World Meteorological Organization's Global Atmospheric Observation network, recorded the highest spring carbon dioxide concentrations in the region. The global average atmospheric carbon dioxide concentration in 2012 was 393.1 ppm, compared with 278 ppm in pre-industrial times.

As a result, the World Health Organization has called for the importance of environmental protection, and reducing carbon dioxide emissions from the gas fire industry has made new energy regulations a priority.

After the 1970s, HFC-227ea/FM200 was found in Europe and other places. Hfc-227ea/FM200 is a kind of chemical fire control, both of which are clean gases of physical fire extinguishing agent. Colorless, tasteless, non-conductive, does not pollute protected objects, will not cause damage to property and precision facilities; Can reduce the concentration of fire, reliable B, C fire and electric fire; The storage space is small, the critical temperature is high, the critical pressure is low (ODP value is zero), stay in the atmosphere for 31 ~ 42 years, meet the requirements of environmental protection, especially in the ozone layer, the ozone layer is non-destructive, the residual time in the atmosphere is relatively short, its environmental performance is obviously better than halogenated alkane, is developed more successful clean gas fire extinguishing agent, It is considered one of the best products to replace haloalkanes 1301,1211
