Monitoring method of desulfurization device in thermal power plant and monitoring system using the method

Abstract

The invention provides a monitoring method for a desulfurization device in a thermal power plant, which is characterized in that it includes the following steps: S1, the first SO in the power plant control host computer control data acquisition system 2 The sensor works to detect SO in the flue gas fed into the absorption tower 2 concentration and output real-time SO2 concentration ρ 1 , the power plant control host gets the real-time SO2 concentration ρ 1 ; S2, power plant control host through real-time SO2 concentration ρ 1 Judging the operating condition that the desulfurization device should be in, and obtaining the operating condition number X; S3, the power plant control host accesses the remote service system through the network connection device, the remote service system receives the operating condition number X, and according to the operating condition number X, the Hadoop Find the optimal operation control parameter group X in the optimization database in the platform and return the found operation control parameter group X to the power plant control host; S4. The power plant control host receives the operation control parameter group X and controls desulfurization according to the operation control parameter group X The work of each device in the device.

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...
