Flusher.
Background technique
Coal-burning power plant is generally all configured with Wet Limestone Desulfurization system at present.Wet Limestone Desulfurization system can not only
The SO2 in flue gas is removed, there are also dust removing effects, conventional desulfurization dust removing effects can achieve 40~70% for spray column, and flue gas is through pot
It is drawn on flue after furnace air-introduced machine, then after booster fan (if there is), into absorption tower.The desulfurizing and purifying in absorption tower,
After demister removes water mist, atmosphere is discharged into through chimney by flue.
The drop of flue gas entrainment after desulfurization should be collected in the demister that absorption tower exports, and make the droplet content of neat stress
No more than guarantee value.Therefore collecting on demister has lime stone drop, under normal circumstances demister periodic flushing, is removed by measurement
Day with fog pressure difference is blocked under serious conditions, must start cleaning procedure at once it may determine that whether demister blocks.Demister blocking
It will cause demister without being rinsed when serious and collapse, desulphurization system is stopped transport, and host is caused to stop.Therefore accurate measurement removes
Day with fog pressure difference is the key that guarantee that desulphurization system operates normally.
