Abstract

The embodiment of the invention provides a method and device for detecting the temperature of a rotary kiln. The method includes the steps that a first temperature and a second temperature are collected, the first temperature is the temperature of a first temperature point, the second temperature is the temperature of a second temperature point, the first temperature point and the second temperature point both correspond to the same position on the outer wall of the rotary kiln and are located at the positions of different depths in a kiln lining of the rotary kiln, and the first temperature point is more close to the inner wall of the rotary kiln; a first distance and a second distance are obtained, the first distance is the distance from the first temperature point to the inner wall of the rotary kiln, and the second distance is the distance from the second temperature point to the first temperature point; the current state of the kiln lining is determined; the temperature of the inner wall of the rotary kiln is obtained according to the first temperature, the second temperature, the first distance, the second distance and the state of the kiln lining. According to the method and device for detecting the temperature of the rotary kiln, the complex physical quantity of heat flow density which is not convenient to measure and calculate can be eliminated, the temperature detecting process is greatly simplified, and the temperature measuring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rotary kiln temperature detection, in particular to a rotary kiln temperature detection method and device. Background technique [0002] Rotary kiln is a high-temperature kiln that can rotate continuously. It is a thermal equipment for drying and roasting materials. It is widely used in the process of non-ferrous smelting, iron and steel metallurgy, chemical industry, cement, alumina, building materials, refractories and other industries. middle. The temperature in the rotary kiln will directly affect the quality of roasting, but the temperature in the kiln is not convenient for direct measurement, so in the existing technology, you can use the soft measurement method for indirect measurement, that is, first measure some other parameters, and then through calculation Obtain the temperature in the kiln (that is, the temperature of the inner wall). [0003] However, the inventor found in the process of re...
