[0034] as attached figure 1 The experimental structure and attached figure 2 The structure of the dryer is shown, and the experimental system is composed of a humidifier, a gas sampler 1, an air pump 4, an instrument wind generator 6, an air compressor, a Nafion tube 8, a filter, and a dew point meter. The working process is: the humidifier humidifies the air around the gas sampler 1, measures the surrounding temperature, enters the gas sampler 1 and is heated by the heating part 7 in the gas sampler 1, measures the dew point temperature at the outlet of the gas sampler 1, and passes through 5um The microporous filter 2 and the 0.2um microporous filter 3 filter, and then the air pump 4 inputs the sample body into the flow meter to measure and limit the flow. The process gas is then heated to maintain the temperature of the sampler. Finally, the treated gas enters the dryer 5 consisting of Nafion tubes 8 . The 16L / min air produced by the air compressor passes through the in...
