The utility model discloses a control device used for double-alkaline flue-gas desulphurization, especially relating to the online-monitoring and automatic controlling in the desulphurization-process. The desulphurization tower of the utility model is connected with the circulation pool through piping. And the gas-inlet and gas out-let are respectively set at the bottom-end and the top-end of the desulphurization tower. The circulation pool links the gas-inlet through the piping and short tube spraying-pump and also links the top of desulphurization tower through piping and circulation pump. An inlet temperature alarm, an inlet flow-indicator, inlet SO [2], concentration-indicator and inlet pressure-meter are set at the gas-inlet. An outlet flow-indicator, outlet SO [2], concentration-indicator and outlet temperature alarm are set at the gas-outlet. A pressure-difference alarm is set in the middle of desulphurization tower. The utility model fully takes flow, concentration, temperature and Ph value, etc many variable data of the off-gas into account and can get the information of each aspect of desulphurization system in time and also can carry out the effective long-distance controlling.
