Method for monitoring desulphurization device of thermal power plant and monitoring system using same

Abstract

The invention provides a method for monitoring a desulphurization device of a thermal power plant. The method is characterized by comprising step S1: a power plant control host controls a first SO2 sensor in a data acquisition system to work, to detect the concentration of SO2 in flue gas supplied into an absorption tower and output real-time SO2 concentration rho1, and the power plant control host obtains a real-time SO2 concentration rho1; step S2: the power plant control host judges operating conditions under which the desulfurization device should be through the real-time SO2 concentrationrho1, to obtain an operating condition serial number X; step S3: the power plant control host accesses a remote service system via a network connection device, the remote service system receives theoperating condition serial number X, searches for an optimal operation control parameter set X in an optimization database in a Hadoop platform according to the operating condition serial number X andreturns the found operating condition serial number X to the power plant control host; and step S4: the power plant control host receives the operation control parameter set X and controls the operation of each device in the desulfurization device according to the optimal operation control parameter set X.

Description

technical field [0001] The invention relates to the operation control of a desulfurization device in a thermal power plant, in particular to a monitoring method for a desulfurization device in a thermal power plant and a monitoring system using the method. Background technique [0002] Thermal power plants produce a large amount of SO in the process of burning and generating flames during the power generation process 2 Therefore, desulfurization devices are necessary in thermal power plants to meet the emission standards stipulated by the state. [0003] In the prior art, the desulfurization device includes: a limestone slurry preparation device for preparing limestone into limestone slurry, and the limestone slurry prepared by the limestone slurry preparation device is transported to a limestone slurry storage tank, and the limestone slurry storage tank is connected with a storage tank for storing slurry therein. The limestone slurry delivery pump that is transported to th...
