Specific implementation mode
As shown in Figure 1, boiler flyash carbon content detects timesharing sampler, structure includes loudspeaker injection pipe 1, probe tube
2, flange 3, sampling bend pipe 4, sampling coupling tube 5, connecting plate 6, protection ceramics 7, integrated cavity 8, sampler 14；Wherein loudspeaker
Injection pipe 1 and probe tube 2 are connected and fixed by flange 3, and the bottom of flange 3 is equipped with connecting plate 6；The tail portion of loudspeaker injection pipe 1 connects
Sample bend pipe 4 is picked up, the tail portion connection sampling coupling tube 5 of probe tube 2, sampling bend pipe 4 is by sampling coupling tube 5 and integrated cavity 8
Import connection, the outlet for integrating cavity 8 connects sampler 14.
The probe tube 2 is equipped with several sampling mouths, and protection ceramics 7 are posted in the outer surface of probe tube 2, for improving
The wear-resisting and high temperature resistance of probe tube 2 is suitable for a variety of sampling environments.
The structure of the sampler 14 includes that touch-screen display module 9, PLC microprocessors 10 are identical with 3 structures
Sampling slip, every sampling slip include back-blowing device 11, receive apparatus for ash 12, operated pneumatic valve 13；It is logical wherein to receive apparatus for ash 12
It crosses operated pneumatic valve 13 to connect by pipeline with the outlet of integrated cavity 8, receive on the pipeline that apparatus for ash 12 is connect with operated pneumatic valve 13
Equipped with back-blowing device 11；Operated pneumatic valve 13 and back-blowing device 11 pass through cable connection PLC microprocessors 10, PLC microprocessors 10
Input/output terminal connect touch-screen display module 9；PLC microprocessors 10 control operated pneumatic valve 13 and back-blowing device 11 respectively
It realizes that ash and blowback are received in timesharing, and control process is shown in touch screen 9.
When practical operation, determines sample point on the surface of boiler flue, according to the determination position of sample point, removed after blowing out
Flue layer cuts open a square hole on sample point surface, sampler rebound is covered and is welded on the square hole edge outputed
On；Sampling mouth on probe tube is stretched into the square hole held successfully, is installed on horizontal or vertical flue less than 1/2 flue height
Position makes sampling mouth in face of flow of flue gas direction, and blending bolt is fixed on sampler rebound；After sampling, remove
Sampler is covered the square hole on rebound with sampler cover board, to ensure the sealing of the flue in boiler operatiopn.
In sampling process, PLC microprocessors 10 start to receive ash by controlling the opening receipts apparatus for ash 12 of operated pneumatic valve 13, utilize
