1. a continuous feeding device of nitrite gas, comprise nitrous acid ester gas generation system, purification system and storage plenum system, described preparation system comprises the corrosion-proof solenoid valve of the standby and conputer controlled of polytetrafluoro liner reactor, electric mixer, polytetrafluoro liner vitriol oil storage tank, logical nitrogen vacuum means, nitrous acid ester gas generation system is stored in storage tank, for micro catalytic evaluation device through the gas produced that once feeds intake after purification system;

  • After raw material consumption is complete, close the pipeline between preparation system and storage tank;

    At this moment, the gas in storage tank can continue for micro catalytic evaluation device;

    Preparation system can prepare nitrous acid ester gas again, when gas to be generated rises to certain pressure, opens the pipeline between preparation system and storage tank, thus realizes the continuous supply of nitrous acid ester gas;

    Wherein;

    purification system comprises reflux exchanger, constant temperature circulating tank and drying tower;

    Store plenum system and comprise nitrous acid ester gas reservoir, corrosion-resistant stainless steel vacuum pressure gauge, pressure maintaining valve and transport pipe.
