Embodiment:
Such as Fig. 1, a kind of total cross-section smoke sampling online monitoring system 100 is present embodiments provided, for out of flue 200 Fume sample is obtained, and sample is sent to flue gas automatic monitored control system 190 and is detected.The total cross-section smoke sampling is supervised online Control system 100 includes sampler 110, pretreatment unit 120 and flue gas automatic monitored control system 190, and sampler 110 is from flue Be transported to pretreatment unit 120 after flue gases are obtained in 200, flue gas is dried, mix after be sent to flue gas and supervise automatically Control system 190 (being schematic diagram in figure), unnecessary flue gas is returned to from pretreatment unit 120 in flue 200.
As shown in Figure 1, Figure 2 and Fig. 3, sampler 110 includes three probe tubes 112 and three delivery pipes 114, probe tube 112 Connect to form L-type with delivery pipe 114.Probe tube 112 is connected with flue 200, and multiple thief holes are provided with probe tube 112 1122, thief hole 1122 is arranged on the diverse location of cross section in flue 200.Thief hole 1122 it is not of uniform size, according to sampling The flow velocity of flue gas determines the size of thief hole 1122 at hole 1122.For the big position of flow velocity, thief hole 1122 is smaller;For The small position of flow velocity, thief hole 1122 is larger.During specific design, the flow field of flue 200 can be imitated to by simulation software True simulation, obtains the speed flowing field of flue gas, the speed of diverse location is determined according to speed flowing field, so as to further determine that difference The size in position sample hole 1122.
Such as Fig. 1 and Fig. 3, total cross-section smoke sampling online monitoring system 100 also includes setting in controller 130, delivery pipe 114 Solenoid valve 116 and velocity measuring device 118 are equipped with, velocity measuring device 118 is arranged on the downstream of solenoid valve 116, Solenoid valve 116, velocity measuring device 118 are electrically connected with controller 130 respectively.By adjusting opening for solenoid valve 116 Degree can adjust the size of flue gas flow in delivery pipe 114, equivalent to choke valve;Velocity measuring device 118 is used to measure electromagnetism The flow velocity of the downstream fume gas of regulating valve 116.Due to flue gas by solenoid valve 116 after, its speed can produce fluctuation, with flue gas Away from solenoid valve 116, its speed can gradually be stablized, therefore velocity measuring device 118 should be as far as possible from solenoid valve 116 Far.Solenoid valve 116 and velocity measuring device 118 can directly be bought, and the present embodiment is not described further.
Such as Fig. 1 and Fig. 4, pretreatment unit 120 includes concetrated pipe 124, heater 128 and windmill 129, the He of heater 128 Windmill 129 is arranged in concetrated pipe 124.Concetrated pipe 124 is L-type pipe, including is connected as the first paragraph 1242 and the of an entirety Two section 1244, first paragraph 1242 is used to be connected with delivery pipe 114, and second segment 1244 is used to be connected with flue 200.Heater 128 Be arranged on windmill 129 in first paragraph 1242, windmill 129 just facing to windward side.Heater 128 is heating wire, and with External power supply (not shown) is connected.
Connecting tube 126 is provided with the first paragraph 1242 of concetrated pipe 124, connecting tube 126 is with flow of flue gas direction in sharp Angle is set, so that flue gas can enter flue gas automatic monitored control system 190 in flowing with very well.In second segment 1244 End is provided with gas jet pump 150, gas jet pump 150 the second end end in probe tube 112 and concetrated pipe 124 Gas produces certain draft so that gas more can successfully flow through probe tube 112 and concetrated pipe 124.
Flue gas automatic monitored control system 190 is commonplace in the prior art, and the present embodiment is not further described.
In other embodiments, connecting tube 126 can also be arranged on the second segment 1244 of concetrated pipe 124, and is connected The flow direction setting at an acute angle of pipe 126 and flue gas in second segment 1244;Such as Fig. 5, connecting tube 126 can also be arranged on first paragraph 1242 and the junction of second segment 1244, and connecting tube 126 is perpendicular to second segment 1244, the air inlet direction of connecting tube 126 Windward side.
The assembling process of total cross-section smoke sampling online monitoring system 100 is as follows:First, by heater 128 and windmill 129 It is installed in concetrated pipe 124, gas jet pump 150 is arranged on to the gas outlet of concetrated pipe 124;Then, probe tube 112 is installed Onto flue 200, and the thief hole 1122 on probe tube 112 is caused to be located at the diverse location on the cross section of flue 200;Will set Pipe 124 is connected with flue 200 so that the gas outlet of concetrated pipe 124 is located inside flue 200;Finally, by connecting tube 126 and cigarette Gas automatic monitored control system 190 is connected.
The direction of arrow is flow of flue gas direction, the work of total cross-section smoke sampling online monitoring system 100 in such as Fig. 1, figure Principle is as follows:Because the gas outlet of flue 200 is provided with air exhauster, the gas outlet of concetrated pipe 124 is provided with gas jet pump 150.Flue gas in flue 200 enters multiple probe tubes 112 by thief hole 1122, and is converged to from multiple probe tubes 112 In concetrated pipe 124.Flue gas is dried by heater 128 in concetrated pipe 124, dried flow of flue gas to windmill Windmill 129 is driven to rotate after on 129, the rotation of windmill 129 allows flue gas to be sufficiently mixed.Due to connecting tube 126 and flue gas Flow direction it is at an acute angle set, therefore the flue gas after dry mixed can compare and be smoothly through connecting tube 126 and enter flue gas Automatic monitored control system 190.Further, since monitoring of the moisture to automatic monitored control system in flue gas can produce interference, therefore heater The drying of 128 pairs of fume samples can further reduce data error.
It should be noted that the present embodiment is preferred embodiment, in other embodiments, gas jet can also be not provided with Pump 150, the negative pressure produced by the air exhauster of the gas outlet of flue 200, flue gas can also enter sampler 110 and pretreatment In device 120, and enter eventually into flue gas automatic monitored control system 190;Or windmill 129 can also be not provided with, by multiple The flue gas of delivery pipe 114 is converged to be mixed naturally in concetrated pipe 124;Or the quantity of delivery pipe 114 can also be two or more Other quantity;Or in other embodiments, thief hole 1122 can also be sized to it is consistent, as long as can guarantee that Thief hole 1122 be arranged on flue 200 not by position, i.e., from different position samples, acquired sample just has certain It is representative.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former Within then, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
