Background technology
As Environmental air quality requirements are higher and higher, the dynamics of monitoring is increasing, to chemical industrial park air
The monitoring of pollution level becomes the most important thing, and how to carry out comprehensive air quality monitoring, is to first have to solve the problems, such as.
In the past when being monitored to air pollution degree, in order to meet the needs of comprehensive monitoring, each monitoring point needs
A variety of toxic and harmful gas factors are monitored, using the combination of multiple single-factor gas sensors；Although such combination
It can achieve the purpose that comprehensive monitoring, but the mating a set of signal conditioning circuit of each single-factor gas sensor and shell etc.
Attachment, monitoring cost input is higher, and in the occasion for needing large area air monitering, the contradiction that monitoring requirements are put into great number is very
Sharply.
Also there is the gas monitoring instrument that can monitor the multiple gases factor simultaneously at present, several lists are installed in a gas chamber
The array of factor gas sensor composition, is successively detected the monitored gas across gas chamber；But existing electrification
Learn multiple-factor gas monitoring instrument and be limited to 4 ~ 6 kinds of gas factors of monitoring mostly, reason be each sensor can with it is monitored
Gas is chemically reacted, and the monitored gas componant across gas chamber can gradually change, i.e.,：Close to the sensing of air inlet of air chamber
Device and the gas componant that the sensor close to gas chamber gas outlet is monitored are inconsistent, the reliability and number of sensors of monitoring result
It is inversely proportional；Therefore, existing air monitering cost is still relatively high.
Invention content
The technical problem to be solved by the present invention is to provide a kind of sensor gas of electrochemistry multiple-factor gas monitoring instrument
Room can solve the sensor array that existing electrochemistry multiple-factor gas monitoring instrument uses and monitor gas across gas chamber successively,
Gas componant can be made to change, monitoring result reliability and number of sensors cost inverse ratio limit number of sensors, air monitering
The higher problem of cost.
The utility model is achieved through the following technical solutions：
A kind of sensor gas chamber of electrochemistry multiple-factor gas monitoring instrument, including shell, and be respectively communicated with shell into
Tracheae, escape pipe, the shell go to upper and lower the cylindrical shape of both ends sealing, and the shell inner cavity is provided with coaxial both ends sealing
Inner cylinder, the air inlet pipe from upper head plate be inserted into shell inner cavity be connected to inner cylinder inner cavity, escape pipe from bottom plate be connected to shell
Inner cavity；Be connected with the partition board that polylith axially extends between the outer wall of the inner cylinder and the inner wall of shell, adjacent partition board with
The outer wall of inner cylinder, the inner wall of shell form a sensor cavity, and the upper end sealing of the sensor cavity, lower end are connected in shell
Chamber is provided with multiple stomatas for being respectively communicated with inner cavity and each sensor cavity on the inner cylinder.
The further scheme of the utility model is that the upper end of the sensor cavity and inner cylinder is sealedly attached to the upper end of shell
Back, the upper head plate are connected through a screw thread with side wall；Sensor cavity is opened while opening upper head plate, is conveniently replaceable, ties up
Protect sensor.
The further scheme of the utility model is, partition board described in polylith be equably connected to inner cylinder outer wall and shell it is interior
Between wall；Make to enter monitored gas enter sensor cavity flow velocity it is consistent, concentration is consistent, and further increase monitoring result can
By property.
The utility model compared with prior art the advantages of be：
It is synchronous to be monitored into multiple sensor cavities after monitored gas enters inner cylinder, it will not interfere with each other, it is ensured that each
The consistency of the monitored gas of sensor, and then ensure the reliability of monitoring result, overcome the limitation of number of sensors, can drop
Low latitude gas monitoring cost.
