Bubble absorption tube or impact absorption tube is selected to carry out air pollution analyte detection, bubble absorption tube absorptivity should reach 90%, at present
The bubble absorption tube absorptivity used is in 90%-92.5%.Part detection method considers the problem, absorbs to improve using second level and inhale
Yield, if indigo method method detects air ozone in public places sanitary inspection, second level absorption spot sampling is cumbersome,
Increase the workload and calculation amount of the detection in laboratory simultaneously.And most pollutants in air detections point such as formaldehyde, ammonia, hydrogen sulfide
Analysis method still uses first order absorption, since bubble absorption tube absorptivity used at present is relatively low, causes testing result than practical
Destination sample object concentration is low.Therefore, the accuracy that improve pollutants in air testing result will consider to improve pollutes in air
The absorptivity of object spot sampling.
Existing sampling absorption plant, aspiration pump built in sampler, sampler connect bubble absorption tube gas outlet, air pollution
Object enters from air inlet, by absorption tube, forms bubble and ramps from absorbing liquid bottom spilling across absorbing liquid, bubble diameter
Greatly, with absorbing liquid contact surface is small, time of contact is few, bubble is destination sample object absorbed liquid is inhaled in contact process with absorbing liquid
It receives, absorption efficiency is not high.When existing bubble absorption tube connection sampler is sampled, often there is suck-back phenomenon, i.e. absorbing liquid is inhaled
Enter sampler, damages sampler.Therefore there is an urgent need for a kind of novel technical solutions to improve bubble absorption tube in the prior art
Absorptivity increases the accuracy of pollutants in air testing result, improves suck-back phenomenon, protects sampler.

Closed cover closes between closed tube mouth, and 1 lower part of absorption tube is horizontally arranged with porous glass plate, and porous glass plate is by sodium borosilicate glass system
It is 200nm~250nm at aperture, offers air inlet pipe hole in the middle part of porous glass plate, the bottom of the air inlet pipe is through air inlet pipe hole
The downside of porous glass plate is extended to, escape pipe is also communicated on the side wall on absorption tube top, and be arranged with safety trocar on escape pipe,
Be provided with gas permeable polymer anti-suck film in safety trocar, safety trocar detachably with replacement, the gas permeable polymer anti-suck
Polytetrafluoroethyldispersion dispersion resin film, Golders film or novel waterproof film can be selected in film.
Preferably, the pyramidal structure that nozzle is inside ground is absorbed, corresponding absorb at nozzle is matching in air inlet pipe
Outer wall ground tapered tube configuration, to seal therebetween；
Preferably, the air inlet pipe hole is ground bellmouth wide at the top and narrow at the bottom, on the lower part of the air inlet pipe is narrow under being also
Wide conical pipe, and the internal diameter that outer diameter and air inlet pipe hole at air inlet pipe hole are corresponded in air inlet pipe matches, corresponding air inlet pipe hole
The outer wall of the air inlet pipe at place is also ground structure, passes through ground sealing structure between the two；
Preferably, absorption tube includes the upper absorption tube on top and the lower absorption tube of lower part, and upper absorption tube and lower absorption tube are
Integral structure, and the diameter of upper absorption tube is greater than the diameter of lower absorption tube；
Preferably, the lower end of the air inlet pipe and lower absorption bottom of the tube reserve certain dispersion at a distance of 5mm for lower part bubble
Space；
Preferably, outlet pipe outer wall is ground structure, and escape pipe is linked with safety trocar by buckle type structure, condom
Inside pipe wall is also ground structure；
Compared with prior art, bubble absorption tube provided by the utility model changes existing sampling absorption plant structure, empty
Pollutant is big by absorption tube formation bubble diameter in gas, with the problem that absorbing liquid contact surface is small, time of contact is few.By porous
Plate dispersion absorbs bubble diameter, increases bubble and absorbing liquid contact surface, and reduction partial size increases bubble simultaneously and contacts in absorbing liquid
Time improves the absorptivity of bubble absorption tube, increases the accuracy of pollutants in air testing result, while being provided with condom
Pipe prevents absorbing liquid to sucking sampler, in terms of protecting sampler, has highly important practical significance.
