And recording information such as sampling flow rate, sampling time, sampling point environment temperature, pressure and the like during acquisition. The collecting tube should be analyzed as soon as possible, otherwise, the collecting tube is wrapped with aluminum foil and then put into a PE self-sealing bag, a label is attached, the bag is stored in the dark below 4 ℃, and the analysis is completed within 7 d.

In the scheme, the method comprises the following steps: the air outlet pipeline of the drying bottle is divided into a plurality of branch pipes which are respectively connected with the air inlet ends of different collecting pipes, the air outlet ends of all the collecting pipes are connected with the sampling pipeline through pipelines, and valves are respectively arranged on all the branch pipes. A plurality of samples can be collected in parallel, and the sampling efficiency is improved.

In the scheme, the method comprises the following steps: the adsorbent is an enax-TA adsorbent or a Tenax-GR adsorbent, and the particle size is 60-80 meshes. The filling amount of the solid adsorbing material is not less than 200 mg/tube. For trapping volatile organic components. MiningBefore sampling, the temperature is 300 ℃ under N ₂ (99.999%) purge activation for 1h.

In the scheme, the method comprises the following steps: at least two layers of pore plates are arranged in the middle of the buffer bottle at intervals from top to bottom, and air holes in the adjacent pore plates from top to bottom are arranged in a staggered mode. The multilayer pore plate is favorable for removing water vapor, so that the water vapor is condensed into water drops, and the water vapor in the smoke is removed as far as possible.

In the scheme, the method comprises the following steps: the drying agent is anhydrous calcium sulfate.

In the scheme, the method comprises the following steps: still include the sampling case, catch pipe, flowmeter, sampling pump, buffer bottle, drying bottle, catch pipe and sampling pump and all install in the box, be provided with the intake pipe on the air inlet of buffer bottle, the intake pipe stretches out outside the sampling case, and the length that stretches out the sampling case is less than or equal to 2cm. The sampling box can be provided with a box door, so that the drying agent can be conveniently replaced, the collecting pipe can be installed and taken out, and the carrying is convenient.

Compared with the prior art, the beneficial effects of the utility model are that: because the content of water vapor in the smoke in the hot pot restaurant is high, the direct use of the collecting pipe can cause the water absorption blockage of the adsorbent, and the effect of adsorbing volatile organic compounds can not be achieved. Therefore, the buffer bottle is designed, the pore plate is arranged in the buffer bottle, most of water vapor can be condensed on the pore plate and drops into the buffer bottle, a small amount of water vapor is adsorbed by the drying agent in the drying bottle, then the flue gas enters the collecting pipe again, and the blocking phenomenon of the collecting pipe is avoided.
