Embodiment Construction

[0111] Taking the steel ball coal pulverization system used in the alumina sintering rotary kiln as an example, as shown in Figure 1, the coal pulverization process consists of a coal feeder, a coal mill, a coarse powder separator, a bag filter, and a pulverized coal bin, etc. Equipment composition. The raw coal and hot air are ground and dried in the ball mill, and the pulverized coal enters the coarse powder separator under the action of the exhaust fan, and the returned powder returns from the section warehouse to the mill to continue grinding. The powder is sent into the pulverized coal bin by the conveying device.

[0112] The specification of the coal mill is Φ3.2×9.5m, and the designed production capacity is 28t / h. The coal mill is divided into three warehouses: drying bin, ball bin and section bin; the main motor model is YR80-8 / 1180, and the rated power is 800KW.

[0113] The coal pulverizer system has the following measuring instruments installed as required by this...

Abstract

A pulverized coal fineness soft-sensing method in a powder-making process based on a least squares support vector machine depends on a hardware platform, measuring instruments and a computer system used for performing a software calculation, wherein said software performs a soft-sensing through real-time process data obtained by a controlling computer of a data collector. Said method comprises the steps of selecting assistant variables, determining the structure of sample data, determining sample components, building a soft-sensing model based on the least squares support vector machine and performing the model training, parameter selection as well as the model validation and the model parameter emendation. The present invention is applied simply and easily, has a lower cost, has more accurate soft-sensing results, and helps to achieve an optimal control and an optimal operation of a pulverizing process.

Description

technical field [0001] The invention belongs to the technical field of automatic measurement, and particularly relates to the final product of the mid-storage steel ball mill coal pulverization system composed of a steel ball coal mill, a coarse powder separator and a cloth bag collector for pulverized coal grinding in the pulverization process—coal The method of soft measurement of powder fineness index. Background technique [0002] In pulverization production, the medium-storage steel ball coal mill consisting of steel ball coal mill, coarse powder separator and cloth bag collector is widely used to grind coal powder to the fineness range required by the process. The fineness of pulverized coal is an important process index for evaluating the pulverization process, an important factor to improve product quality and economic benefits, and plays a very important role in the process control of coal-fired power generation and sintering. At present, in the industrial applicat...
