2, pretreatment

Heating the probe (temperature 150 degrees);

The probe filter element is 2μm (sampling time is 50 minutes, 0.6Mpa air pressure gas is pulsed backflushing, and the cycle is 2 minutes.;

Constant power heating cable (temperature 130 degrees, temperature difference, SO2 loss)

The filtration in the cabinet is 1μm and 0.5μm, respectively, to ensure the purity of the sample gas.

The pre-pump is added to achieve the sample gas drop of 130 ° C to condense 4 ° C ± 0.1 ° C. The entire process takes less than 5 seconds. Therefore, SO2 can be considered as no loss. The peristaltic pump discharges the condensed water and collects it in the reservoir.

Increase the tar filter.
