Abstract

The invention discloses a coal mill pipeline blockage state determination method and device, a storage medium and computing equipment. The method comprises the steps of acquiring historical operationdata of a coal mill, and extracting air outlet dust pressure data and multiple pieces of influence factor data related to the air outlet dust pressure data; establishing a multiple regression model bytaking the air outlet dust pressure data as dependent variables and taking a plurality of influence factor data related to the air outlet dust pressure data as independent variables; training the model to delete the influence factor data of which the correlation coefficient with the air outlet dust pressure data is less than a threshold value, and matching weights for the influence factor data ofwhich the correlation coefficient with the air outlet dust pressure data is greater than or equal to the threshold value to obtain a regression equation; evaluating the dust pressure data of the airoutlet of the coal mill according to the current operation data of the coal mill, and determining the blockage state of the coal mill pipeline. The technical problem that in the prior art, the accuracy of predicting the blocking state of the coal mill pipeline is low is solved.

Description

technical field [0001] The present application relates to the technical field of coal pulverizers, in particular, to a method, device, storage medium and computing equipment for determining the clogging status of coal pulverizer pipelines. Background technique [0002] Blockage of the coal mill pipeline not only affects the safe operation of the boiler, but serious blockage may also cause spontaneous combustion of pulverized coal, damage the coal-fired pipeline, seriously affect the normal operation of the unit and grid connection, and is not conducive to energy saving and environmental protection of power generation enterprises. In order to improve the economic benefits of power generation enterprises, power generation enterprises pay more and more attention to and strengthen the purge management of coal mill pipelines. However, the blockage of coal mill pipelines is a very complicated problem, because there are many factors that affect the blockage, and it is not economical...
