Slime filter cake moisture influence factor evaluation method based on grey correlation analysis

Abstract

The invention relates to a slime filter cake moisture influence factor evaluation method based on grey correlation analysis. The slime filter cake moisture influence factor evaluation method based on grey correlation analysis includes the steps: clearly knowing about the influence factor and the factor level of the slime filter cake moisture; measuring the test data of the filter cake moisture under each factor level; utilizing the grey correlation analysis method to solve the Deng'S correlation degree of each factor between the slime filter cake moisture; and through ordering of magnitude of the correlation degree, clearly knowing about the main influence factor of the slime filter cake moisture. The slime filter cake moisture influence factor evaluation method based on grey correlation analysis has the advantages of simplicity, practicality, low calculated amount, and accurate calculated result, and can effectively determine the significance of each factor on the slime filter cake moisture and provide theoretical basis for effectively reducing the filter cake moisture.

Description

technical field [0001] The invention relates to an analysis method of moisture influencing factors of coal slime filter cake, in particular to an evaluation method of moisture influencing factors of coal slime filter cake based on gray relational analysis. Background technique [0002] With the increasingly serious situation of coal, people's requirements for coal quality are gradually increasing, and among the many quality indicators of coal, moisture plays a decisive role. With the development of coal preparation technology, in most coal preparation plants, wet coal preparation occupies the main position, and the problem brought about by this is that the moisture in the final coal product needs to be removed. In the end, if the moisture content of coal is too high, it will not only bring additional economic burden to transportation, but it is estimated that millions of tons of transportation capacity will be wasted in my country every year due to high moisture content; Thi...

Problems solved by technology

[0004] However, the existing research is to study one or several factors affecting the moisture of the filter cake separately, and it is concluded that each factor has a certain influence on the moisture of the filter cake, and the degree of influence of each factor on the moisture of the filter cake has not been proposed. The purpose of the present invention is to propose a method that can obtain the degree of influence of various factors on the moisture of the filter cake, and then effectively determine the degree of contribution of each factor to the moisture of the filter cake, and provide a theoretical basis for targeted reduction of the moisture of the filter cake in future production practice
