The operation of the multi-temperature measuring apparatus inside the reactor according to the embodiment of the present invention configured as described above will be described.

First, the first and second protective pipes 400 and 300 on the left side of the flange 500 'are inserted into the measuring device inlet 9 of the reactor 1 to be measured, and the flange 500' is fixed to the outside of the reactor 1. Let's do it.

Subsequently, when the reactor 1 is operated, the reaction site 3, the boundary between the first and second fireproof materials 10 and 11, the boundary between the second and third fireproof materials 11 and 12, and the third fireproof material ( 12) and heat at the boundary of the reactor outer wall (2) is sensed through each of the first, second, third and fourth sensor parts (23, 33, 43, 53), and according to the detected heat, Thermoelectric power is generated from the 3, 4 element wires 20, 30, 40, and 50 and applied to the external measuring device through the terminal 620 of the head 600.

At this time, the external measuring device analyzes the thermoelectric power generated in the first, second, third, fourth element wires (20, 30, 40, 50), and the first, second, third refractory materials mounted in the reactor 1 ( By determining the temperature distribution of the 10, 11, 12 and the reaction site 3, it is possible to determine the suitability of the material and the construction amount (thickness) of the refractory material.

In addition, when the temperature of the reaction site 3 cannot be determined due to the breakage of the first sensor unit 23 during the experiment, the change of the temperature sensed by the second sensor unit 33 is determined to determine the reaction site 3. Infer temperature.

In addition, when the operation of the reactor 1 proceeds normally, the temperature detected by the first sensor unit 23 is measured to be the highest, and the farther away from the reaction site 3, that is, the second, third, and fourth sensor units 33, 43, 53), the lower the temperature is measured.

At this time, if any part of the refractory material is broken, especially if the space expansion between the constructed refractory material occurs, the hot gas is moved through the part, and the temperature of the sensor part of the specific part is rapidly increased due to the hot gas, The presence of abnormalities can also be identified.

In addition, since the rectangular fixing plate 630 is used in the terminal box embedded in the head part 600, and the terminals 620 are arranged in two rows on the fixing plate 630, the processing of the conducting wire is clean.

Meanwhile, in the above example, three refractory materials are installed inside the reactor, and thus four sensor parts and four wires are installed. However, the number of sensor parts and wires may vary according to the increase or decrease of the number of refractory materials.

As described above, the multi-temperature measuring apparatus inside the reactor according to the present invention includes a plurality of sensor parts and a first and second protective tube in which a plurality of sensor parts and element wires connected to the sensor parts are inserted into a reactor in which multiple refractory materials having different thermal conductivity are installed. Once installed, it is possible to determine the suitability of the material and construction quantity (thickness) of the refractory material by measuring the temperature distribution inside the reactor, and when the temperature of the reaction site cannot be determined due to breakage of the first sensor part, the second sensor part By detecting the change in temperature can be inferred from the temperature of the reaction unit.

In addition, another effect is that when the breakage in any part of the refractory material, especially when the expansion of the space between the construction of the fire retardant occurs, the hot gas is moved through the part, the temperature of the sensor part of the specific part is rapidly increased because of this hot gas It is also possible to identify the abnormality of the fire.
