The utility model is used for the gaseous collection has prevented effectively when the gas flow rate is bigger than normal that the absorption liquid rushes the phenomenon of gas sampling ware, guarantees gaseous going on smoothly of gathering, the buffering ball of disconnect -type makes things convenient for hydrophobicity filtration membrane's setting, makes things convenient for the joining of absorption liquid simultaneously, and after the use, makes things convenient for gaseous absorption tube's washing.
Description
Technical field
This utility model relates to a kind of GAS ABSORPTION pipe.
Background technology
During gas collecting, gas sampler controls the air-flow of gas and sucks in regulation flow rates, when gas and absorbing liquid are sufficiently mixed and react, GAS ABSORPTION pipe is easily generated a large amount of bubble, although there being buffering ball above absorbing liquid, but when flow velocity is bigger than normal, absorbing liquid is easily rushed in gas sampler, cause gas sampling failure.Additionally, the problem that traditional GAS ABSORPTION pipe exists not easy cleaning, is easily broken, and when gathering gas under high dust atmosphere, in gas, particulate matter enters absorbing liquid and causes result to produce the deficiency of deviation.
Because above-mentioned defect, the design people, the most in addition research and innovation, a kind of prevent absorbing liquid from entering gas sampler, easy cleaning, dust-proof gas collecting device to founding so that it is to have more the value in industry.
Summary of the invention
For solve above-mentioned technical problem, the purpose of this utility model be to provide a kind of prevent absorbing liquid enter gas sampler, easy cleaning, dust-proof GAS ABSORPTION pipe.
GAS ABSORPTION pipe of the present utility model, including being provided with the U-tube body of air inlet and gas outlet, described body is provided with the buffering ball connected with described tubular body at gas outlet, and described buffering ball internal 1/3-2/3 place opens and is provided with adjustable for height hydrophobic filter film.
Further, described buffering ball includes using threaded, ground connection or the upper hemisphere of bayonet connection and lower hemisphere.
Further, it is provided with dust-break mechanism at the air inlet of described body.
Further, described air inlet is trumpet-shaped absorption mouth, and described dust-break mechanism is located in described absorption mouth.
Further, described dust-break mechanism is dust removal filter element or non-woven fabrics.
Further described filter membrane is PTFE material or PP material.
Further, described GAS ABSORPTION tubing matter is PP material or PE material.
Such scheme, the present invention at least has the advantage that
This utility model is used for gas collecting, and (1) effectively prevent the absorbing liquid when gas flow rate is bigger than normal and rushes in the phenomenon of gas sampler, it is ensured that being smoothed out of gas collecting；(2) buffering ball of separate type facilitates the setting of hydrophobic filter film, facilitates the addition of absorbing liquid simultaneously, and after a procedure, facilitates the cleaning of GAS ABSORPTION pipe；(3) it is provided with dust-break filter element or non-woven fabrics at air inlet, effectively prevents dust from entering absorbing liquid, it is to avoid deviation occurs；(4) the GAS ABSORPTION pipe of PP material or PE material can use as medical disposable material, and relative to traditional glass gas absorption tube, PE material is convenient for carrying, the most broken, and it can be avoided that the material of the previous run residual impact on test result.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is a kind of embodiment structural representation of buffering ball in GAS ABSORPTION pipe；
Fig. 3 is a kind of embodiment structural representation of buffering ball in GAS ABSORPTION pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
See Fig. 1 to Fig. 3, a kind of GAS ABSORPTION pipe described in this utility model one preferred embodiment, including the U-tube body 1 being provided with air inlet 3 and gas outlet 4, described body 1 is provided with the buffering ball 6 that connect internal with described body 1 at gas outlet 4, opens and be provided with adjustable for height hydrophobic filter film 2 at the internal 1/3-2/3 of described buffering ball 6.
The placement of filter membrane 2 for convenience, facilitates the addition of absorbing liquid simultaneously, and after a procedure, facilitates the cleaning of GAS ABSORPTION pipe, described buffering ball 6 to include using threaded 8, ground to connect 9 or the upper hemisphere 12 of bayonet connection 10 and lower hemisphere 13；When upper hemisphere 12 and lower hemisphere 13 ground connect, in order to prevent upper hemisphere 12 and lower hemisphere 13 from being disconnected gas leakage by the pressure of air-flow, being equipped with the outside projection of a circle 7 up and down at ground, described protruding 7 are provided with the fixation clamp 11 that some fastening grounds connect.
For effectively preventing dust from entering absorbing liquid, it is to avoid deviation occurs in result, is provided with dust-break mechanism 5 at the air inlet 3 of described body 1.
For convenience of putting into of dust-break mechanism 5, described air inlet 3 is trumpet-shaped absorption mouth, and described dust-break mechanism 5 is located in described absorption mouth.
Preferably, described dust-break mechanism 5 is dust removal filter element or non-woven fabrics.
Preferably, described filter membrane 2 is that PTFE material or PP material, PTFE material and PP material have corrosion-resistant, the advantage of good stability, is suitable for the use of various absorbing liquid.
The carrying of absorption tube, the most broken for convenience, and it can be avoided that the impact on test result of the material of previous run residual, described GAS ABSORPTION tubing matter is that PP material or PE material, PP material or PE stable material quality are preferable, corrosion-resistant.
When absorption tube is used for gathering oxides of nitrogen gas, in order to realize lucifuge, described body 1 is brown.
Operation principle of the present utility model is as follows:
nullBuffering ball 6 is opened，Absorbing liquid is added in body 1，Filter membrane 2 is placed in the position of 1/2 in buffering ball 6，Then upper hemisphere 12 and lower hemisphere 13 are merged and fix，When in atmospheric environment, dust granules is more，Dust-break filter element or non-woven fabrics is put at air inlet 3，After GAS ABSORPTION pipe installs，Gas outlet 4 is by hose connection gas sampler，After connection，Open gas sampler and gas flow rate is set，Gas enters absorbing liquid by being plugged with the air inlet 3 of dust removal filter element or non-woven fabrics，When gas sampler arrange when gas flow rate is bigger than normal or has bubble to produce after absorbing liquid and gas reaction，Filter membrane 7 in buffering ball 6 can effectively prevent absorbing liquid from rushing in gas sampler，After collection，Open upper hemisphere 12 and lower hemisphere 13 absorbing liquid to be taken out，Purge gas absorption tube；When GAS ABSORPTION pipe uses PE material, can use as medical disposable material, it is not necessary to clean, the GAS ABSORPTION pipe more renewed uses standby next time, is prevented effectively from result and deviation occurs.
The above is only the preferred embodiment of the present invention; it is not limited to the present invention; should be understood that; for those skilled in the art; on the premise of without departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
