The invention provides a model-based semi-dry flue gas treatment control system, the system includes: a data acquisition device for collecting process data related to the reaction process of the semi-dry reaction tower; a model parameter optimization unit, including a model A processing unit and a parameter optimization unit, the model processing unit uses the dynamic flue gas processing model to calculate the output variables related to the control parameters of the semi-dry reaction tower using the process data as input variables, wherein the output variables predict The flue gas emission parameters related to the flue gas output from the semi-dry reaction tower, the parameter optimization unit calculates the optimal control parameters of the semi-dry reaction tower according to the output variables; the automatic control module is used to The semi-dry reaction tower is automatically controlled according to the optimized control parameters. According to the present invention, the optimal control in the flue gas treatment process is realized, and the energy saving and consumption reduction of the system are realized.
Description
technical field [0001] The invention relates to the field of garbage disposal, in particular to a model-based semi-dry flue gas disposal control system. Background technique [0002] The flue gas deacidification process for waste incineration power generation includes dry, wet and semi-dry methods. The semi-dry deacidification has high purification efficiency, simple process, less equipment, easy disposal of products, no secondary pollution and convenience. The advantages of regulation and control are widely used in waste incineration power generation process. [0003] The high-temperature flue gas generated after waste incineration enters the semi-dry reaction tower, and the toxic acid gases HCl and SO in the flue gas 2 , At a certain temperature (150 ~ 165 ℃), it contacts with the sprayed lime slurry after atomization to produce a chemical reaction to remove the acidic harmful gas. In order to achieve a good deacidification effect while improving the utilization rate of ...
