Abstract

The invention provides a flue gas desulfurization oxidation system fault prediction method based on a machine learning algorithm. The machine learning algorithm model is applied to fault prediction and early warning of the oxidation air system of the flue gas desulfurization device. Through machine learning, historical operation data of the wet desulphurization device are analyzed by adopting an OLS linear regression algorithm model, internal logic of each operation characteristic parameter and the oxidation performance of the desulphurization device is mined, a principle model of an oxidation reaction is dominated, and the method is used for fault prediction of the wet desulphurization device. And operators can conveniently master the health state of the oxidation air system of the desulfurization device in real time. Fault prediction and early warning of the oxidation air system of the wet desulphurization device are realized, an algorithm model participates in operation control, and the power consumption of an oxidation fan can be reduced by reducing the excess amount of oxidation air, optimizing the density and the PH value of oxidation liquid and reducing the liquid level height of an oxidation tank in time, so that the operation cost of the desulphurization device is reduced.

Description

technical field [0001] The invention belongs to the field of industrial flue gas treatment, and in particular relates to a method for predicting a failure of a flue gas desulfurization oxidation system based on a machine learning algorithm. Background technique [0002] my country is a large country of coal. At present, coal is still the main fuel for industrial use. While coal releases heat during combustion, it also produces a large amount of particulate matter, SO 2 , greenhouse gases and other pollutants, causing ecological environment pollution. Wet flue gas desulfurization technology is one of the desulfurization methods commercially applied in the world. It can efficiently remove sulfur oxides in flue gas, and the by-products are easy to recycle resources. It is a good way to control atmospheric SO 2 Pollution most effective flue gas desulfurization technology. Contains SO 2 The flue gas enters the desulfurization device, and in the desulfurization tower is in cont...
