Controller 160 is connected with electromagnetic valve of flow control 180, for controlling the water flow in cooling water pipe 150；Temperature sensor
170 are arranged in connecting tube 140, and temperature sensor 170 is connected with controller 160.Controller 160 is controlled using PLC, and PLC exists
It is commonplace in the prior art, controller 160 is not described in detail.
Due to being provided with cooling water pipe 150 in connecting tube 140, flue gas monitoring device is passed into so as to effectively reduce
The temperature of flue gas in 130, prevents high-temperature flue gas from bringing harmful effect to the service life of flue gas monitoring device 130.Also, work as cigarette
When temperature degree is higher, temperature sensor 170 gives the signal of controller 160, and controller causes the aperture of electromagnetic valve of flow control 180 to become
Greatly so that it is big by the cold water quantitative change of cooling water pipe 150, improve cooling effect.When flue-gas temperature is relatively low, controller 160 makes
It must be diminished by the cool water quantity of cooling water pipe 150.
The operation principle of whole flue gas online monitoring system 100 is as follows：Flue gas in flue 200 is entered by probe tube 114
Enter to pretreatment unit 120, after heat drying mixes, a part enters flue gas monitoring device 130 by connecting tube 140
Middle its composition of monitoring；Another part is returned in flue 200.Because the diameter of flue 200 is bigger, the diverse location in same section
The flue gas flow rate difference of different time is larger.Probe tube 114 in the present embodiment is provided with barrier sheet 1148, can cause flue
The smoke sampling amount of diverse location is as far as possible consistent in 200, ensures the accuracy of data.When the flue gas flow rate of a certain position is larger
When, in the presence of flow of flue gas, the power that barrier sheet 1148 is subject to is bigger, so that the mouth of pipe direction towards remote probe tube 114
Rotate, now, the gap between barrier sheet 1148 and probe tube 114 reduces, i.e., the flow area of probe tube 114 reduces.When
When the flue gas flow rate of a certain position is smaller, then the flow area of probe tube 114 is larger.Therefore, can cause as far as possible in flue 200
The smoke sampling amount of diverse location is as far as possible consistent.
It should be noted that the present embodiment is preferred embodiment, in other embodiments, can on the tube wall of probe tube 114
To be not provided with limited block 1149, now, from the bigger torsionspring of stiffness factor, ensure that barrier sheet 1148 will not be in flue gas
Opened under effect towards the direction of connection end 1144 of probe tube 114；Or windmill 126 or heater 124 can also be not provided with.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, 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., it should be included within the scope of protection of the utility model.
