Embodiment 1

[0024] Such as figure 1 As shown, the present embodiment provides a method for wiring a furnace body temperature measurement optical cable, which is used for wiring on a furnace body with a connecting pipe 5, and only performs wiring and temperature measurement on the furnace body 4, and in the furnace body 4 Two rows of first fixing devices 2 and first nuts 21 arranged perpendicular to the ground plane are welded on the surface, and the distance between adjacent first fixing devices 2 is 500mm. The arc-shaped spring pieces 22 corresponding to the two rows of first fixing devices 2 are respectively relatively placed. The optical cable 1 is bypassed from the arc-shaped spring piece 22 of the first first fixing device 2 in the first column at the starting point of the wiring, reversely wound to the first first fixing device 2 in the second row, and from the second row to the first fixing device 2. The arc-shaped spring piece 22 of the first first fixing device 2 in the first ro...

Embodiment 2

[0026] Such as figure 2 As shown, this embodiment provides another method for wiring the furnace body temperature measuring optical cable. Compared with Embodiment 1, this embodiment, in addition to the temperature measurement of the furnace body 4 wiring as in Embodiment 1, also measures the temperature of the furnace body 4. The connection pipe 5 of the body is used for wiring temperature measurement. Such as image 3 As shown, the connecting pipe 5 of the furnace body is divided into a first part 51 and a second part 52 from the axial direction. Weld two rows of first fixing devices 2 respectively on the surface of the second part 52, and weld the first nut 21 on each turn of the serpentine cable wiring; At the same time, the first part 51 on the furnace body connecting pipe 5 is bypassed in turn on each of the first fixing device arc-shaped spring pieces 22, so that the optical cable is snaked from the furnace body connecting pipe 5 head to the furnace body connecting p...

Abstract

The invention belongs to the technical field of distributed sensing and temperature measurement, and specifically relates to a fixing device and a method for wiring an optical fiber cable for temperature measurement of a furnace body. Wiring is carried out on a furnace body with connecting pipes, and two rows of first nuts are welded on the surface of the furnace body body. The arc-shaped spring pieces corresponding to the two rows of first fixing devices are placed opposite to each other; the optical cable is wound from the first first fixing device in the first row at the starting point of the wiring, and reversely wound to the first first fixing device in the second row. At the fixing device, repeat the winding until the end point of the wiring; press the first fixing device pressing plate on each arc-shaped spring piece, and fasten all the first fixing devices with the first bolts respectively. The unevenness of the furnace body is fixed by a second fixing device. The present invention solves the problem of thermal expansion and contraction of the optical cable by installing the first fixing device during the wiring of the optical cable; it can use one optical cable for wiring from the beginning to the end; by installing the second fixing device, the joint between the main body and the connecting pipe is solved And the measurement accuracy of the uneven surface of the furnace body.

Description

technical field [0001] The invention belongs to the technical field of distributed sensing temperature measurement, and in particular relates to a fixing device and a furnace body temperature measurement optical cable wiring method, which is suitable for measuring the surface temperature of large and medium-sized high-temperature furnace bodies such as blast furnaces, converters, and gasification furnaces. Background technique [0002] During the production and operation of large and medium-sized high-temperature furnaces such as blast furnaces, converters, and gasifiers, the temperature of the furnace body surface is usually measured for safety reasons. The two most commonly used temperature measurement technologies are distributed fiber optic temperature measurement and thermocouple temperature measurement. Among them, the principle of the distributed optical fiber temperature measurement system to obtain the spatial temperature distribution information is: the use of ligh...
