Abstract

The invention discloses a method for measuring the thickness of a slag layer for fly ash melting treatment. Voltage data is collected every 0.5s, and the trend of the voltage changing with time is depicted; it is cyclically judged whether the electrode voltage is greater than a set value; The height of the bottom layer is judged; the cycle judges the number of times N that the voltage changes from rising to falling in a unit time interval; when N is greater than the set number of times, calculate the voltage change range from rising to falling in turn, and judge the voltage within the time interval. Whether the amplitude of change exceeds the preset value of amplitude change; if the amplitude of change exceeds the preset value of amplitude change within this time interval, the height of the upper layer of the slag layer is judged; the slag layer is calculated according to the data of the height of the upper side of the slag layer and the height of the bottom layer of the slag layer thickness. The invention improves the accuracy of the thickness measurement of the slag layer.

Description

technical field [0001] The invention relates to a method for measuring thickness, in particular to a method for measuring the thickness of a molten slag layer used in the melting treatment of fly ash. Background technique [0002] The invention patent with the patent number CN201710305547.6 discloses a new double-electrode DC arc system for fly ash melting, which discusses the method of processing fly ash in a DC arc melting furnace. The Joule heat in the slag layer is mainly distributed in the depth range of several centimeters below the surface of the molten pool. It has been discussed in the patent "A Method for Measuring the Thickness of the Slag Layer of a Hazardous Waste Furnace", in order to judge that the thickness of the slag layer is lower than the critical thickness, the method was developed for real-time measurement of the slag layer thickness. [0003] This method needs to manually judge the moment when the tip of the electrode separates from the metal layer an...
