Industrial kiln temperature measuring device and method and maintenance method

Abstract

The invention provides an industrial kiln temperature measuring device and method and a maintenance method. The device comprises one or more radial grooves, a first temperature measurement optical fiber and a temperature measurement sensing module. The one or more radial grooves extend to a lining of an industrial kiln along the radial direction of the industrial kiln; the first temperature measurement optical fiber penetrates through the radial groove, one end of the first temperature measurement optical fiber is connected with the lining, the other end of the first temperature measurement optical fiber is connected with the temperature measurement sensing module, and the radial groove is matched with the first temperature measurement optical fiber; and the temperature measurement sensingmodule is used for transmitting an optical signal and converting the output optical signal into a temperature signal. The one or more radial grooves are formed and extend to the lining of the industrial kiln in the radial direction of the industrial kiln, the first temperature measurement optical fiber is arranged to penetrate through the radial groove, one end of the first temperature measurement optical fiber is connected with the lining, the other end of the first temperature measurement optical fiber is connected with the temperature measurement sensing module, and the radial groove is matched with the first temperature measurement optical fiber, so that omnibearing and full-coverage monitoring of the temperature of the lining of the industrial kiln is realized, and potential safety hazards in production of the industrial kiln are reduced.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an industrial kiln temperature measuring device, method and maintenance method. Background technique [0002] A large number of industrial furnaces are high-temperature reaction vessels, such as blast furnaces. For high-temperature reaction industrial furnaces, it is necessary to detect and warn the lining temperature to prevent safety accidents such as high-temperature molten iron burn-through in blast furnaces, which will cause huge economic losses to enterprises. . [0003] At present, industrial kilns mainly rely on thermocouples arranged in the lining of industrial kilns to monitor and infer the temperature and working status of the lining. 1m to 3m, the number of temperature monitoring points is limited, and there is a large monitoring blind area between two adjacent thermocouples, which makes it impossible to better realize the all-round and full-coverage monitoring of ...
