Description

Technical Field

[0001] The utility model relates to the technical field of atmosphere sampling, in particular to oxidation auxiliary equipment for atmosphere sampling. Background Art

[0002] Atmospheric sampling refers to the method of collecting samples of pollutants or polluted air in the atmosphere. One type of collection method is to pass a large amount of air through a liquid absorbent or solid adsorbent. The other is to use a container (glass bottle, plastic bag, etc.) to collect air containing pollutants. Sometimes it is necessary to sample the air at high altitudes.

[0003] When collecting toxic gases that require oxidation treatment, the oxygen content in the air at high altitudes is limited, which can easily lead to incomplete oxidation conversion, which not only affects the sampling efficiency, but also affects the sample collection data, and is not practical. Utility Model Content

When in use, the sampler body, drying cylinder, porous glass plate tube and mixing tube are installed and placed in sequence (the drying cylinder can be installed or not as needed), and are interconnected through connecting hoses. Then the plateau oxygen generator is controlled to prepare oxygen and input it into the oxygen inlet tube through the oxygen supply tube. At the same time, the sampler body starts to inhale, driving the outside air into the oxygen inlet tube for preliminary mixing with the oxygen, and then the air is inhaled into the tube body cavity to be mixed again by contact with the spiral strips, and finally enters the mixing chamber to be completely mixed by contact with the rotating stirring plate. Then the mixed gas passes through the porous glass plate tube and the drying cylinder into the sampler body to complete the sampling.

[0009] Preferably, the diameter of the oxygen inlet tube is larger than the diameter of the tube body cavity.

[0010] Preferably, the diameter of the spiral strip is adapted to the diameter of the tube body cavity, and the length of the spiral strip is adapted to the length of the tube body cavity.

[0012] Preferably, a plurality of interference flow holes are formed through both sides of the stirring plate.

[0013] Preferably, a buffer bottle is connected to the connecting hose between the drying cylinder and the sampler body.

[0014] The beneficial effects are:

[0015] Oxygen is prepared by controlling the plateau oxygen generator and input into the oxygen inlet tube through the oxygen supply tube. At the same time, the sampler body starts to inhale, driving the outside air into the oxygen inlet tube for preliminary mixing with the oxygen, and then inhaled into the tube body cavity for re-mixing through contact with the spiral strips, and finally enters the mixing chamber for complete mixing through contact with the rotating stirring plate. Subsequently, the mixed gas passes through the porous glass plate tube and the drying cylinder into the sampler body to complete the sampling. By setting up the oxygen production mixing equipment, the oxidation reaction can be made more complete, thereby improving the accuracy of the sample data and the sampling efficiency.
