Gas controlling device is mainly used in sampling to the composition of gas, analyzing, existing gas controlling device mainly comprises controller, detection cavity and gas drainage device, gas analysis sensor is provided with in detection cavity, by gas analysis sensor, the gas entered in detection cavity is monitored, analyzed, then gas information is sent to controller, carry out the transmission of data and the control of gas drainage device by controller, detect with the gas sampling carried out next time.But, due to the detection cavity of current gas controlling device, be all suck new gas to be detected while discharging the gas detected, like this, gas to be detected will be formed mix with to detect gas, thus affects gas-monitoring result, accuracy of detection is poor, is unfavorable for the analysis to gas.Meanwhile, the steam in air also can impact the detection of gas, reduces the degree of accuracy of gas detect further.
Utility model content
For prior art above shortcomings, the purpose of this utility model is how to solve existing gas controlling device monitoring poor accuracy, be unfavorable for the problem of the analysis to gas, a kind of detection cavity on-line cleaning structure of gas controlling device is provided, can effectively improve gas-monitoring precision, thus make to detect more accurately gas componant, and extend the serviceable life of sensor.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is such: a kind of detection cavity on-line cleaning structure of gas controlling device, comprise controller, detection cavity, gas detection sensor and gas collection pump, the outlet side of described detection cavity is connected with gas collection pump inlet end, the control end of this gas collection pump is connected with controller, described gas detection sensor to be installed and is connected with controller with in detection cavity, it is characterized in that: be connected with a moisture trap at the inlet end of detection cavity, the inlet end of described moisture trap is connected with admission line, outlet side is connected with the inlet end of detection cavity, a three-way solenoid valve is also provided with between moisture trap and detection cavity, the inlet side of described three-way solenoid valve is connected with the inlet end of detection cavity, one of three-way solenoid valve goes out end and is connected with moisture trap, and another goes out end and puts sky, and the control end of this three-way solenoid valve is connected with controller.
Further, described gas detection sensor is one or more in CH4 sensor, H2S sensor, CO sensor, SO2 sensor, O2 sensor, NH3 sensor and oil gas sensor.
Further, the dead end of putting of described three-way solenoid valve is connected with a breather line.
Compared with prior art, the utility model tool has the following advantages: structure is simple, by moisture trap by the moisture removal in air, divides and causes interference to the detection of gas, and extend the serviceable life of sensor to prevent water; After one-time detection completes, three-way solenoid valve is controlled by controller, make the inlet side of three-way solenoid valve and put dead end and be connected, then gas collection pump is opened, like this, gas collection pump by detection cavity with detect gas discharge while, air is passed in detection cavity, thus realize the on-line cleaning of detection cavity, impact detecting next time to avoid detecting gas, thus effectively can improve the precision of gas detect, and then improve the survey degree of accuracy of gas controlling device prison, be more conducive to the detection to gas, analysis.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-controller, 2-detection cavity, 3-gas detection sensor, 4-gas collection pump, 5-moisture trap, 6-three-way solenoid valve.
Embodiment
