Abstract:
     A quick and continuous method for prodn. of carbon dioxide uses sulfuric acid and ammonium bicarbonat as raw material through chemical reaction to produce CO2 gas. Said method can continuously produce CO2,its yield is 360-2500 cubic meter per hour, pressure is 0.6 HPa and concn. is 100%. The gas prodn. speed, flow and pressure can be optionally regulated. Besides the CO2 is used for extinguishing fire, it can also be used in granary preservation, agricultural plastic greenhouse plant CO2 gas fertilizer to promote growth. The invented CO2 gas prodn. equipment need not use electric power simple in operation, service life longer than 10 years.
