Problems solved by technology
The field test method has high reliability, but the cost of carrying out is high, the repeatability is poor, and the scope of working conditions covered is limited, so the scope of application is small
The optimal scheduling method of slurry circulating pump based on material balance is directly calculated according to the design value. The method is simple, has good repeatability, and covers a wide range of working conditions. The actual application effect of the obtained results is difficult to guarantee

Embodiment 1
[0062] In order to solve the problem of large energy consumption in the desulfurization system of the power plant, the present invention proposes an optimal scheduling method for the desulfurization system slurry circulation pump based on process data scanning, such as figure 1 shown. The method includes the following steps: combining the mechanism analysis and the actual measuring points on the spot to select the factors that affect the desulfurization rate; scanning the variable data selected before the pump change from the historical database of the target unit, as working condition constraints, and scanning out the pump combination at the same time The change of desulfurization rate of the system after the change is used as the impact data of the pump combination change on the desulfurization effect under the working condition; the scanned data is divided into different data sets according to the change of different pump combinations; when the process conditions meet the op...

The invention discloses a slurry circulating pump optimization dispatching method based on process data scanning, and belongs to the technical field of circulating pump optimization dispatching. The slurry circulating pump optimization dispatching method mainly comprises the steps of (1) variable selection; (2) data scanning and combination dividing; and (3) slurry circulating pump real-time optimization dispatching. The step of data scanning and combination dividing further comprises the sub-steps of (2a) scanning process data and (2b) performing combination dividing. The step of slurry circulating pump real-time optimization dispatching further comprises the sub-steps of (3a) optimizing a trigger condition of dispatching; and (3b) performing slurry circulating pump combination optimization. According to the slurry circulating pump optimization dispatching method based on process data scanning, data of influences imposed on a desulfurization effect by variations in slurry circulating pump combination in the history of a set is scanned from the process data, and optimization dispatching is performed on the current slurry circulating pump, so that a defect of narrow coverage area of sample operating conditions acquired in a field test method is overcome, and the application range of slurry circulating pump optimization dispatching is expanded. Meanwhile, compared with the field test method, the method disclosed by the invention is low in required cost and convenient to operate.
Description
technical field [0001] The invention belongs to the technical field of optimal scheduling of circulating pumps, and in particular relates to an optimal scheduling method of slurry circulating pumps based on process data scanning. Background technique [0002] With the release of the National Development and Reform Commission and the Ministry of Environmental Protection's "Environmental Protection Electricity Prices for Coal-fired Generator Sets and Operation Supervision Measures for Environmental Protection Facilities", the state's efforts to control energy conservation and emission reduction continue to increase, and power plants are facing more and more pressure to control pollutant emissions. bigger and bigger. SO 2 As one of the main pollutants emitted by power plants, the control of its emission concentration is a key area of concern for power plants. [0003] In many SO 2 Among control technologies, wet desulfurization technology, as a relatively mature desulfuriz...
