Fig. 1 is the structural representation of moving source tail gas on-line monitoring of the present invention and pollutant sampling system.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and example the present invention is described in further detail.But it is not as a limitation of the invention that institute gives an actual example.
Fig. 1 is moving source tail gas on-line monitoring provided by the invention and pollutant sampling system synoptic diagram.Scheme specifically comprise moving source travel parameter test system, the dilution commingled system, sampling system and on-line monitoring system.
The moving source parameter test system that travels comprises elbow 1, tail gas stream buret 2, flowmeter 3, temperature sensor 4, humidity sensor 5, elbow 25.Moving source tail gas enters flowtube from elbow 1, and unnecessary tail gas flows out from elbow 25.In addition, the parameter test system that travels also comprises an OBD-Link or GPS, by junctor motor-car OBD interface or the speed, engine speed and the operating range that adopt vehicle-mounted mode record move source to travel.Have two interfaces 6 and 7 on the flowtube, interface 6 is used for connecting five gas analyzer 8, carries out CO, CO
2, NO
2, O
2, THC density real-time monitoring.It should be noted that carrying out moving source when test, need to guarantee OBD-Link(or GPS) writing time and five gas analyzer, particle on-line monitoring instrument be consistent.The result who records like this can be used for the relation research of moving source discharging and the speed of a motor vehicle, rotating speed.The dilution commingled system comprises heating pipeline 9, mixing chamber 11, Zero gas generator 24, mass flow controller 26, humidity sensor 12, temperature sensor 13.Air enters Zero gas generator 24 with other pollutant removals such as water, particle and organism, and the pure air that obtains is lowered the temperature at the abundant mixed diluting of mixing chamber 11 processes as carrier gas and the tail gas from interface 7 and the heating pipeline of flowing through.Can regulate the flow of carrier gas by mass flow controller 26, by the total flow that the mass flow controller 16,21 of sampling system can be regulated sampling gas, the adjusting of above flow can determine to enter the flow of mixing chamber tail gas, thereby determines dilution ratio.Temperature sensor 13 is positioned at the mixing chamber outlet place, can show in real time mixture temperature.By regulating dilution ratio to guarantee that mixture temperature is below 50 ℃.Tail gas after the dilution passes through the particle cutting head (such as PM
