Abstract

The invention provides a method and device for detecting the correlation of coking and coalification behaviors. The device is composed of a control system, a coking coalification system, an electronic balance, a colloidal viscosity and thickness detector, an internal pressure detector, a volume deformation detector, and a pressure control system; under constant volume or constant load conditions, real-time , Simultaneous detection of colloidal viscosity (v) and thickness (y), volatile analysis rate (f) and precipitation rate (df / dt), colloidal internal pressure (p) and volume during coking and coalification Expansion and contraction (x), etc.; by processing the data, obtain the coking coalification behavior correlation curve and the probe resistance change curve, and divide the gelatinous layer into resistance rising area, resistance falling area and constant resistance area according to the resistance curve and the resistance steep rise area, and the thickness of the gelatinous layer, the thickness of each structural region at different carbonization times, and the characteristic parameters that characterize the carbonization behavior and the viscosity of the gelatinous body are obtained.

Description

Technical field [0001] The present invention relates to a coal quality evaluation method and a technical field thereof, and more particularly to a method and apparatus for detecting a correlation between coking coal-based behavior. Background technique [0002] When industrial coke, the coking coal should be experienced in a thermoplastic phase with the temperature rise. During the period, the coal is softened, melted to form a glue body having a viscous flow characteristic and a volatile analysis, expansion pressure generation, contraction and expansion of the material layer, which determine the bonding ability of Coking coal and coke quality, or even Impact push and coke oven life. Therefore, the characteristics of this stage when compiling coal is fully understood, which is of great significance for coke production. [0003] At present, the evaluation of the thermoplastic stage characteristics is mainly based on the characteristics of the thermoplastic stage, which is mainly c...

AI Technical Summary

Problems solved by technology

This invention patent can realize the detection of coal pyrolysis-coking behavior under constant pressure conditions, but it cannot simulate the constant volume conditions of industrial coking

In addition, the invention patent needs to manually push and pull the probe to move up and down when measuring the thickness of the colloidal layer, so that the force is different for each measurement, which directly affects the resistance sensed by the probe when it touches the material layer, making the colloidal layer There is an error in determining the position of the upper and lower layers

Moreover, the measurement and data recording cannot be carried out simultaneously. The operator needs to read the display values ​​of the pressure gauge and the displacement gauge first and then manually record them into the form, which makes the measurement result of the thickness of the colloidal layer very subjective, and the operation is cumbersome. labor intensive

Furthermore, the patented method to obtain the characterization indicators of the properties of the colloid body only has the quantitative indicator of the maximum thickness of the colloid layer, but no other indicators
