    Technical field
    [0001] The present invention relates in general to a technology for the treatment of radioactive waste and, more particularly, to an apparatus for measuring the temperature of a glass melting furnace.
    Basic technique
    [0002] Vitrification is preferably used in the treatment of radioactive waste. The vitrification of radioactive waste is a process in which the nuclear species of radioactive waste are bound in a glass matrix, so that vitrification can achieve a stabilized treatment of radioactive waste.
    [0003] To vitrify radioactive waste, radioactive waste is placed inside a glass melting furnace together with fragmented glass so that the radioactive waste is melted with the glass, thus forming molten glass in the furnace. When the molten glass solidifies, the solidified glass that captures the nuclear species of radioactive waste is produced. A conventional temperature measurement apparatus used to measure the temperature of the glass melting furnace is a thermocouple as disclosed in Publication of the Korean Patent Application No. 10-2010-0126922 (KR 20120065668 A). Here, the thermocouple performs temperature measurement while it is in direct contact with an object to be measured, so that a protective tube surrounding the thermocouple is exposed to molten glass at high temperature and is subjected to chemical corrosion. The chemical corrosion of the protection tube reduces the life of the protection tube, and it is necessary to change the protection tube frequently with a new one.

    The best way
    [0015] An exemplary embodiment of the present invention will now be given in detail with reference to the attached drawings.
    [0016] Fig. from 1a to 1d are views which illustrate an apparatus for measuring the temperature of a glass melting furnace according to the present invention, in which fig. 1a is a perspective view, fig. 1b is a sectional view taken along the line A – A ́ of fig. 1a, fig. 1c is a section view taken along the line B – B ́ of fig. 1a and fig. 1d is a section view taken along the line C – C ́ of fig. 1a. Fig. 2 is a sectional view showing the apparatus for measuring the temperature of the glass melting furnace according to the present invention. Fig. 3 is an enlarged view of a through hole in the apparatus for measuring the temperature of the melting furnace of the glass of fig. 2 .
    [0017] With reference to the drawings, the apparatus for measuring the temperature of the glass melting furnace according to the present invention comprises a part with a glass window 1 and a part with a camera 2.
    [0018] The glass window part 1 having a transparent glass window 11 is mounted on a hole for measuring the temperature of the glass melting furnace. Since the glass window part 1 is barrel-shaped, it is provided with the through hole 12 so that the glass window part 1 can communicate with the temperature measurement hole of the glass melting furnace. As described in detail above, the glass window 11 is arranged to cover the through hole 12. Since the glass window portion 1 is barrel-shaped, the through hole 12 extends to the outside of the temperature measuring hole . The glass window 11 is positioned in the through hole distant from the glass melting furnace.
    [0019] The camera part 2 comprises a housing 22 and a thermographic camera 21 present in the housing 22. The thermographic camera 21 measures the temperature of the interior of the glass melting furnace or the temperature of the molten glass through the glass window 11 and the through hole 12 of the glass window part 1.
    [0020] The glass window part 1 and the camera part 2 are combined with the support 3 respectively, so that a rear end of the glass window part 1 is not in contact with the front end of the camera part 2. Consequently, the heat of the glass melting furnace is not directly transmitted to the camera part 2.
    [0021] More particularly, the glass window part 1 is multi-layered, so that the layers can be separated or joined to one another. The multi-layered structure is provided with at least one flow path of the cooling gas through which the cooling gas is introduced from the outside.
    [0022] The multi-layers of the glass window part 1 comprise: a flange plate 13 mounted on the temperature measuring hole; a plate of the body 14 arranged on the flange plate 13; the cover of the plate of the body 15 arranged on the plate of the body 14; a flange of the glass 16 disposed on the cover of the plate of the body 15; a glass support 17 arranged on the glass flange 16; and a glass window unit 18 removably mounted in the glass holder 17. As described below, the glass window unit 18 is slidable and can comprise a plurality of glass windows 11, and is mounted in removably in the glass holder 17. The multi-layers are all combined using a first locking element 191 such as a bolt or screw and a second locking element 192 mounted outside the glass window portion 1. In In particular, the multi-layers are advantageous in that they can flexibly produce a flow path of the cooling gas. In an illustrated embodiment, at least two flow paths of the cooling gas can be formed.
    [0023] A first flow path 51 introduces the cooling gas into the through hole through a side wall of the glass window part 1, and guides the cooling gas to the glass window 11.
    [0024] To accomplish this, the glass window portion 1 of the apparatus for measuring the temperature of the glass melting furnace according to the present invention is provided with the first flow path 51 using the glass flange 16 and a first ring of guide 41. Fig. from 4a to 4c are views illustrating the flange of the glass 16, and figs. 5a and 5b are views showing the first guide ring 41.
    [0025] With reference to figs from 4a to 4c, the flange of the glass 16 is donut-shaped so as to be a part of the through hole 12. An inner wall of the flange of the glass 16 also has an inclined surface 162 which tapers towards the upper part of the inner wall such that the inner diameter of the flange 16 decreases towards the upper part of the inner wall, thus forming the first flow path 51. That is, the inner diameter of the flange 16 increases towards the lower part of the inner side wall of the glass flange . The flange of the glass 16 is also provided with a first gas inlet 161, which is provided to pass through a surface of the inner wall and a surface of the outer wall. Through the first gas inlet 161, the cooling gas can be supplied to the through hole 12. The holes provided on the flange of the glass 16 are locking holes 163, engaged with locking elements, and at least one can be provided.
    [0026] With reference to figs 5a and 5b, the first guide ring 41 is also in the shape of a donut and is housed on the cover of the plate of the body 15, forming the first upward flow path 51 together with the inclined surface 162. The first guide ring 41 has a side wall 413 of a predetermined height so that the cooling gas introduced through the first gas inlet 161 may not be directed horizontally. The first guide ring 41 may also have a chamfered corner 411 cut at a predetermined angle on an outer edge of an upper end of the side wall 413. The lower ends of the first guide ring 41 may also be extended to the outside in the form of a flange so as to be housed stably on the cover of the body plate 15. As can be understood from fig. 3, the first flow path 51, formed by the glass flange 16 and the first guide ring 41 supplies the cooling gas upwardly through all the inner surface of the through hole 12. Accordingly, the surface of the glass window 11 exposed to the through hole 12 can be prevented from being covered by fumes. The fig. from 6a to 6c are views illustrating the cover of the body plate provided in the apparatus for measuring the temperature of the glass melting furnace according to the present invention, wherein FIG. 6a is a perspective view, fig. 6b is a plan view from above, and fig. 6c is a sectional view. The fig. 7a and 7b are views illustrating a second guide ring provided in the apparatus for measuring the temperature of the glass melting furnace according to the present invention, in which fig. 7a is a perspective view, and FIG. 7b is a section view.
    [0027] A second flow path 52 can be formed by the cover of the body plate 15 and the second guide ring 42. The cover of the body plate 15 is donut-shaped so as to be a part of the through hole 12, and a second gas inlet 151 is provided which is provided to pass through a surface of the outer wall to a surface of the inner wall. The lid of the body plate 15 also has a protrusion 152 which tapers downwardly so that the cooling gas introduced through the second gas inlet 151 may not be directed horizontally. The holes provided on the cover of the plate of the body 15 are locking holes 153.
    [0028] The second guide ring 42 on an inner surface has an inclined surface 421 whose diameter is tapered downwards. Consequently, the second downward flow path 52 is provided with a protrusion 422 and the inclined surface 421. The second guide ring 42 can be provided with a flange-shaped protrusion 422 to an outer surface of its inner part . As illustrated in the drawings, the second guide ring 42 is arranged on the plate of the body 14.
    [0029] The second flow path 52 is directed to the temperature measuring hole, so that it can prevent the fumes or heat in the glass melting furnace from being guided towards the glass window 11.
    [0030] Fig. 8 and 9 show the glass support 17 and the glass window unit 18 respectively provided in the glass window portion 1 of the apparatus for measuring the temperature of the glass melting furnace according to the present invention.
    [0031] As shown in Figs. 7a and 7b, the glass support 17 arranged on an upper end of the glass window part 1 is donut-shaped so as to form a part of the through hole 12. The glass support 17 also has guide steps 171 on the sides opposite of the lower surface of the glass support 17. With the guide steps 171 facing down, the glass support 17 is combined with the glass flange 16 using locking holes 172. The glass window unit 18 is inserted slidingly between the guide steps 171.
    [0032] The glass window unit 18 has at least one glass hole 182 provided individually with a glass window 11, and is slidably inserted into the glass support 17. Accordingly, the individual glass window 11 provided in the The glass window unit 18 can be used selectively. For example, the glass window 11 in use can be slidably moved so that the glass window 11 can be cleaned or replaced with another glass window 11.
    [0033] As illustrated above, the part with camera 2 comprises: the housing 22 and the thermographic camera 21 provided in the housing 22. The part with camera 2 is provided with the thermographic camera 21 arranged to photograph the inside of the melting furnace of the glass through the through hole 12 of the glass window part 1. As shown above, the glass window part 1 and the camera part 2 are combined with the support 3 respectively, so that the rear end of the window part of glass 1 is not in contact with the front end of the part with camera 2. Regarding the thermographic camera 21, the infrared light related to the thermographic range varies from 3 to 25 µm. Although the 21 thermographic camera seems to work in a similar way to a video camera, it produces an image by detecting infrared energy rather than visible light.
    [0034] The body 22 of the part with camera 2 is composed of multiple parts. For example, the housing 22 may comprise a first cover 221, a second cover 222, and a third cover 223. In particular, the third cover 223, positioned on one side of the thermographic camera 21, may have a double-walled structure having a space between the internal and external walls of the structure.
    [0035] The glass part of the housing 224 is arranged at a front end of the housing 22, and comprises a glass bracket 2241 and a glass housing 2242 provided in the 2241 glass sheet.
    [0036] The thermographic camera 21 is supported in the housing 22 by the support bracket 225, arranged outside the housing 22 and by the support of the camera 226, arranged inside the housing 22. The reference number 2251 indicates a locking element.
    The third cover 223 of the housing 22 is provided with a cooling gas inlet and a cooling gas outlet, so that a cooling nitrogen gas can be supplied to, and circulated in, the space in the double wall.
