With reference to Fig. 3, structured flowchart and the principle of work of check device 5 are as follows:
Verification gas input commutates to hold by variable valve 25 and second and is connected.Alternatively, the variable valve 25 adoption rate variable valve in the present embodiment, that switching device shifter adopts is a two-bit triplet solenoid valve DCF4, easily expects that switching device shifter also can adopt other electrically-controlled valve or Pneumatic valve.
Alternatively, analytical equipment 6 comprises flow controller 22 and gas analyzer 23, and one end of flow controller 22 is connected with the first output terminal of switching device shifter, and the other end of flow controller 22 is connected with gas analyzer 23.Flow controller 22 is for controlling the constant flow value (general sampling flow is 1L/min) required at analytical equipment 6 of sampling flow.Verify gas input and pass into zero gas or gas as required, the present embodiment arranges NO gas and SO2 gas two input ends.The first commutation end of two-bit triplet solenoid valve DCF4 is communicated with pretreatment unit 4, for being communicated with sample gas passage, the second commutation end of two-bit triplet solenoid valve DCF4 is communicated with verification gas input, for being communicated with gas passage, gas of sampling during normal measurement enters gas analyzer 23 and measures, when the flue gas measured value that data collector 7 is monitored exceedes emission limit, control switching device shifter and switch to the second commutation end, thus gas analyzer 23 is communicated with verification gas input.Gas break-make adopts Valve controlling, and cylinder outlet is equipped with decompression valve, and full bottle gas air pressure is 10MPa, by reduction valve pressure to about 0.5MPa.Reduction valve outlet is connected with pipeline with between two-bit triplet solenoid valve DCF4.
Alternatively, verify gas input and arrange pressure transducer 24, the gaseous tension of gas input verified by pressure transducer 24 for detecting.Pressure transducer 24 is the pressure in order to measure gas bottle, thus monitors the use amount of gas, because along with the use of gas, pressure can reduce gradually, need change gas when pressure drops to lower than system alert during 0.5MPa.Alternatively, data collector 7 gathers the pressure measurement data of pressure transducer 24, when the pressure measurement data detected does not meet the demands, pressure measurement data is flowed to check device 5 by data collector 7, and the verification control device of check device 5 exports cut-offfing of control signal control SO2 transfer valve DDQF1 or NO transfer valve DDQF2.
Workflow: in normal measurement situation, two-bit triplet solenoid valve DCF4 first commutates and holds conducting, gas pathway closure, and namely gas analyzer 23 is only measured sample gas and analyzed under normal circumstances, and gas pathway closure.When the flue gas measured value that data collector 7 is monitored exceedes emission limit, verify control device and control the first commutation end disconnection, second commutation end conducting, this up-to-date style gas pathway closure, and gas passage is opened, verify control device control SO2 transfer valve DDQF1 to open, SO2 gas passes into, flow controller 22 control ratio variable valve 25 controls to ventilation flow rate the flow of needs, pass into 3 ~ 5 minutes analyser measured values to stablize, verify control device control SO2 transfer valve DDQF1 to close, data collector 7 obtains the span data of SO2 and the zero data of NO simultaneously, compare with normal concentration value and calculate and drift about whether in allowed band.In like manner, when verifying gas input input NO gas, verify control device control NO transfer valve DDQF2 to open, NO gas passes into, flow controller 22 control ratio variable valve 25 controls to ventilation flow rate the flow of needs, passes into 3 ~ 5 minutes analyser measured values and stablizes, and verifies control device control NO transfer valve DDQF2 and closes, two-bit triplet solenoid valve DCF4 is switched to sample gas passage, is completed.
Whether data collector 7 obtains the data of NO and the zero data of SO2, compare to calculate drift about in allowed band with normal concentration value.Then illustrate that gas analyzer 23 surveying instrument itself is out of question when drifting in allowed band, detected measurement data is decided to be valid data, then illustrate that when drift exceeds allowed band error appears in gas analyzer 23 apparatus measures instrument, cause measured data inaccurate, therefore be decided to be invalid data.In the present embodiment, emission limit can set arbitrarily, according to actual conditions needs, can set multiple emission limit or numerical intervals, the data that such as exceed standard, zero data, outrange data etc.As can be seen here, adopt verification module of the present utility model, when data collector 7 collects abnormal data, can realize automatically verifying the accuracy of gas analyzer 23, thus realize proving measurement data accuracy.Alternatively, when system needs regularly or automatically detect the zero degree/span drift of gas analyzer 23, only need to send corresponding control command to the verification control device in check device 5.
