Guan Shang, A-frame are fixed in protection pipe with clip, are connect below filter with hand handle.
Further, the temperature sensor is connect with smoke temperature plug, can measure flue-gas temperature, and temperature sensor uses platinum
Thermal resistance temperature sensor.
Further, tracheae component front end is provided with Pitot tube, can measure flue gas flow rate；The setting of sampling pipe front end is fixed
Position column, samples more accurate positioning.
Further, the sampling pipe is tetrafluoroethene pipe, and outside is fixed with heating tape, heating temperature by temperature detect switch (TDS) and
Heat plug control.
Further, the membrane filter can filter the particulate matter in flue gas, and filter membrane is tetrafluoroethene filter membrane.
Further, the absorption bottle is two 75mL impact type absorption bottles, is put into ice bath case, absorbing liquid is allowed quickly to inhale
Hydrogen chloride in getter body.
Further, for the sampling apparatus when acquiring hydrogen chloride sample, flue gas enters sampling pipe, warp after passing through Pitot tube
Heating tape heating is crossed, the moisture in flue gas becomes steam, and subsequently into filter, the filter membrane in filter filters out flue gas
In particulate matter, entered in two concatenated absorption bottles finally by silicone tube, hydrogen chloride is absorbed by liquid absorption.
Beneficial effect
The utility model has the beneficial effects that sampling pipe is tetrafluoroethene pipe and heating can since gas in pipelines has aqueous vapor
To prevent from adsorbing adhesion object in pipe；Membrane filter can filter the particulate matter in flue gas, tetrafluoroethene filter membrane acid-alkali-corrosive-resisting,
Resist various organic solvents, keeps the sample of acquisition purer；Platinum resistance sensor has measurement accuracy height in the prior art,
The advantage that performance has been stablized；Since sampling apparatus heats, flue-gas temperature is higher, and absorption bottle is placed in ice bath case, can allow absorbing liquid
Better absorbing hydrogen chloride improves sampling efficiency；Positioning column can make sampling positioning more accurate, and hand handle keeps device more portable, and three
The labour of angle support saving worker.
