Working principle:
When pulverized coal boiler ignition, the fuel oil that oil gun sprays is lighted with high-energy igniter first, then passes through oil gun point
Burning coal powder.Oil gun work when, the first backwash valve 5, valve plate 8 and third backwash valve 14 be open state, the first residual cake valve 11,
Second residual cake valve 16 and the second backwash valve 13 are in off state；Fuel oil enters the shell of backwash filter 4 by oil inlet pipe 2
In body 6, filter cylinder 7 is filtered fuel oil, and fuel oil is flowed out from the side wall of filter cylinder 7, and impurity stays in inside filter cylinder 7, after filtering
Fuel oil flowed out from shell oil outlet 62, into oil gun pipe 1, when reaching the oil outlet of oil gun pipe 1, atomizer 3 is by fuel oil
Spray atomization；Backwash filter 4 prevents sheet impurity to enter oil gun pipe 1, avoids atomizer 3 and is blocked, ensure that oil
The atomizing effect of rifle improves the stability of unit operation.
In oil gun use process, input pressure table 17 measures the input pressure of backwash filter 4 and transmits measured value
To controller 19, fuel-displaced pressure gauge 18 measures going out oil pressure and measured value being transferred to controller 19 for backwash filter 4；When
After a period of use, the impurity in filter cylinder 7 is more for oil gun, between fuel-displaced pressure gauge 18 and the measured value of input pressure table 17
Difference is greater than the setting value of controller 19, and controller 19 sends shutdown signal to the first backwash valve 5 and control-rod 9, and first is anti-
Flushing valve 5 and valve plate 8 are closed, and controller 19 sends open signal to the first residual cake valve 11, and the first residual cake valve 11 is opened, fuel oil
Into filter cylinder 7, the open end through filter cylinder 7 to the filtering of filter cylinder 7 between valve plate 8 is then out, then is flowed by the side wall of filter cylinder 7
