One gas analysis of the present invention and absorption plant, including intake valve, intake valve connects air relief valve, decompression by conduit
Valve connects flow regulator, and flow regulator connects electromagnetic valve, electromagnetic valve and the internal gas equipped with gas sensor
Fluid measurement device is connected, and gas measurement device connects safety can, and safety can connects air-out apparatus by trachea, and air-out apparatus leads to
Enter to fill the absorption cell of absorbing liquid.
Further, air-out apparatus has funnelform spray structure.
Further, the quantity of gas measurement device is 2 groups.
Further, often group gas measurement device inside be provided with 2-4 gas sensor.
Further, valve it is provided with between gas measurement device and safety can.
Further, safety can is transparent vessel.
Further, one during absorbing liquid is sodium hydroxide, potassium hydroxide, sodium bicarbonate and aqueous hydrogen peroxide solution or
Several.
Further, during gas sensor is sulfur dioxide, carbon dioxide, carbon monoxide, these hydrogen sulfide gas sensor
One or more.
By such scheme, the invention have the advantages that
Air relief valve and flow regulator are set, it is possible to by gas blood pressure lowering to be measured, are adjusted to the threshold value properly measured, improve
The stability of test, gas flow to be measured accurately controls by flow regulator further, it is ensured that test accurate
Property；It is provided with two groups of gas measurement devices, improves the accuracy and precision of measurement；Arrange absorption cell detection tail gas is inhaled
Receive, be conducive to detecting the purification of environment, safety can be set simultaneously, prevent suck-back, extend the service life of device.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of description, be below embodiments of the invention, and coordinate accompanying drawing describe in detail as after.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Hereinafter implement
Example is used for illustrating the present invention, but is not limited to the scope of the present invention.
See Fig. 1, a kind of gas analysis described in a preferred embodiment of the present invention and absorption plant, including intake valve 2, enter
Air valve 2 connects air relief valve 4 by the conduit that material is politef, and air relief valve 4 connects a flow regulator 6, flow
Adjusting means 6 connects has electromagnetic valve 8, electromagnetic valve 8 to be connected equipped with two groups of gas measurement devices 10 of gas sensor 12 with inside,
The number of gas sensor 12 is that often group four, respectively sulfur dioxide, carbon dioxide, carbon monoxide, hydrogen sulfide gas sense
Device.Gas measurement device 10 connects transparent safety can 16, and safety can 16 connects air-out apparatus 18, gasmetry by trachea
Trachea between device 10 and safety can 16 is provided with valve 14, and air-out apparatus 18 is stainless steel, and air-out apparatus 18 has
Funnelform spray structure, air-out apparatus 18 is passed through the absorption cell 22 filling absorbing liquid 20, and absorbing liquid 20 is sodium hydroxide and mistake
The aqueous solution of hydrogen oxide.
The specific works process of the present invention is as follows:
By conduit, gas to be measured is entered air relief valve 4 by intake valve 2, and gas to be measured is carried out blood pressure lowering by air relief valve 4, will pressure
Power just successive step is to an appropriate threshold.Then, post-decompression gas to be measured is through flow regulator 6, flow regulator 6
Gas flow is converted to the numeral shown on a display screen, and tester can be according to the numeral of display, and regulation is treated further
Survey gas flow, thus gas pressure to be measured is adjusted to suitable scope, it is ensured that the safety of test and accuracy.After process
Gas to be measured enter electromagnetic valve 8 from flow regulator 6, subsequently into gas measurement device 10, in gas measurement device 10
Gas sensor 12 work, the content of the composition in the gas to be measured that will detect is converted to electricity, then through circuit conversion, will
