The preferred plan that carries out an invention
(1) at first, according to Fig. 1~Fig. 8 furnace wall observation device of the present invention is described.
Furnace wall observation device of the present invention (below be sometimes referred to as " observing device of the present invention ") to be to have relative high temperature furnace wall 42a and the stove of 42b with narrow and small interval, for example the furnace wall observation device that uses of the inside of pit kiln coking chamber 41 be to looking like.
As filming apparatus 8, can use its controller of camera etc. of CCD photographic camera and control.As Fig. 2, Fig. 4 and shown in Figure 5, can be with visual field direction and the furnace wall 42a and the 42b configured in parallel of filming apparatus 8.And at the visual field of filming apparatus 8 direction configuration minute surface 2 or 2a and 2b, mirror angle will be adjusted into and make when the position of filming apparatus 8 is observed, and the image on surface, furnace wall reflects on minute surface 2 or 2a and 2b.
Usually, as shown in Figure 4 and Figure 5, be 45 degree if make the angle of minute surface 2 or 2a and 2b and furnace wall 42a and 42b, can access from the image on the surface, furnace wall that vertical direction is seen, therefore preferred.
As existing, observing the method for furnace wall from vergence direction, there are vertical minute crack on surface, furnace wall or the problem that the cracking of the puzzle joint between the brick is difficult for seeing, but in observing device of the present invention, can under state, take wall near top view, therefore, can find clearly that the puzzle joint between vertical minute crack or the brick ftractures.
Certainly, when vergence direction is seen the furnace wall, can surface, clear view furnace wall concavo-convex the time, the angle that can make minute surface and furnace wall is the angle outside 45 degree.
In the observation in stove, usually, the distance that makes filming apparatus 8 and minute surface 2 or 2a and 2b is for certain.If the distance of lengthening filming apparatus 8 and minute surface 2 or 2a and 2b just can prolong the effective minute surface length with the furnace wall parallel direction, and can enlarge the visual field 13 of filming apparatus of observation minute surface or the scope (length of long side) of 13a and 13b.
On the other hand, for the furnace wall vertical direction, i.e. effective minute surface width of cross direction because the interval of furnace wall is little, can not enlarge, and can not enlarge the visual field 13 of filming apparatus or the scope of 13a and 13b (length of short brink).
In the observation of pit kiln coking chamber, if making in the filming apparatus visual field 13 on surface, furnace wall or the long side length of 13a and 13b is about 500~600mm, can carry out damage inspection is had the observation of about 1mm of enough spatial decomposition abilities with general CCD photographic camera.In the filming apparatus visual field 13 on surface, furnace wall or the short brink length of 13a and 13b, be about 150~200mm when vertical direction is observed the furnace wall.
As the configuration direction of minute surface or 2a and 2b, shown in Fig. 1~5, can with minute surface vertically be the short transverse of stove, promptly rectangular direction with the depth direction of stove.The depth direction of stove is the direction that moves furnace wall observation device 1 when observing furnace wall 42a and/or 42b, by observing when moving, can accumulate the furnace wall observation result of stove depth direction.
Therefore, vertically be and the rectangular direction of stove depth direction (travel direction) to take the photographing information on surface, furnace wall to greatest extent by making minute surface.
In the present invention, shown in Fig. 1 and Fig. 4~6, be accommodated in the thermally insulated container 3 with the electronics headed by the filming apparatus 8, minute surface 2 or 2a and 2b are configured in the outside of thermally insulated container 3.Thermally insulated container 3 is not supplied with water coolant outside stove, and, power supply wiring and signal wiring do not connected yet.
Therefore, can make the furnace wall observation device light weight and the miniaturization that are configured in the stove, and can be easily in being inserted into stove and the structure that moves, for example, loading and unloading (with reference to Fig. 3) on the coking forcing machine 43 of pit kiln coking chamber 41.
As shown in Figure 4 and Figure 5, thermally insulated container 3 its surfaces cover with thermal insulation material 4, if the short period of time can be trapped in the High Temperature Furnaces Heating Apparatus, inner electronics are normally moved.If in the coking chamber 41 of pit kiln,, therefore, can guarantee that the coking forcing machine 43 that is used for furnace wall observation device 1 is installed inserts in the stove, observes the whole length of stove depth direction and extracts the outer minimum time of stove then out owing to can in stove, be detained 3 minutes.
Thermal insulation material 4 as covering thermally insulated container 3 for example, can adopt ceramic beaverboard or calcium silicate board etc.
In observing device of the present invention,, therefore, the viewing window 16 that is used to guarantee the thermally insulated container 3 in the observing device visual field can be retained in minimal size because minute surface 2 or 2a and 2b are configured in the outside of thermally insulated container 3.
In the prior art that prism is accommodated in the case, must enlarge the size of the viewing window that on case, is provided with, when using thermally insulated container 3, existence invades radiant heat in the container from viewing window and causes the rapid above-mentioned problem of temperature in the container, but, as observing device of the present invention, minute surface 2 or 2a and 2b are configured in the outside of thermally insulated container 3, its result, owing to can dwindle viewing window 16, therefore be retained in inferior limit from the radiant heat of invading here, can prevent that the temperature in the thermally insulated container from rising.
Thermal glasses such as silica glass are installed in viewing window 16.Thermal glass is by means such as metal evaporations, preferably has to see through from the visible light of outside and the function of reflected radiation heat.
In observing device of the present invention, as shown in Figure 4, also can make minute surface is that 1 minute surface 2 is observed a furnace wall 42a.On the other hand, also preferred as the observing device of the present invention of above-mentioned (2) (with reference to Fig. 5), the two piece minute surfaces (2a, 2b) different with angle constitute minute surface, mirror each surface of relative furnace wall (42a, 42b) by each minute surface.
In Fig. 2 and observing device of the present invention shown in Figure 5, the 1st minute surface 2a mirrors the surface of the 1st wall 42a, and the 2nd minute surface 2b mirrors the surface of the 2nd wall 42b, can take the two simultaneously by single filming apparatus 8.
Thus, move the furnace wall observation device of once having taken in a filming apparatus 8, just can obtain the observations on surface, furnace wall, the left and right sides by depth direction at stove.And, can compare furnace wall, the left and right sides simultaneously.
Further, owing to can observe furnace wall, the left and right sides by enough filming apparatus 8, therefore, compare with the situation of taking in two filming apparatus in thermally insulated container inside, can dwindle the port area of the viewing window 16 of thermally insulated container, reduce radiant heat and invade the ratio that causes temperature to rise in the thermally insulated container.
The minute surface of observing device of the present invention, owing to be configured in the outside of thermally insulated container 3, therefore, minute surface directly is exposed to the high-temperature atmosphere in the stove.In the observing device of the present invention of above-mentioned (3), as shown in Figure 5 and Figure 6, make inside hold the surface of container 11 of water coolant 6 as minute surface (2a and 2b).
The time that observing device of the present invention is detained in High Temperature Furnaces Heating Apparatus is the short period of time, if in this time, water coolant 6 temperature in the container 11 rise and boiling, boiling cooling vessel 11, the temperature of container 11 can be remained on the boiling point (100 ℃) of water coolant, just can remain on the minute surface 2a that forms on the vessel surface and the optical property of 2b for a long time, can keep the planeness of minute surface 2a and 2b equally for a long time.
Observing device of the present invention needn't be supplied with water coolant in order to cool off minute surface 2a and 2b outside stove, and needn't use the primary heater unit of minute surface, therefore, can be installed in simply in the running gears such as pit kiln forcing machine.
The container 11 that holds water coolant 6 in inside, as Fig. 2, Fig. 5 and shown in Figure 6, it is microscler to can be made into the cross section orthogonal, is minute surface (2a, 2b) with two faces in 4 outsides, remains two faces and uses thermal insulation material 12 thermal insulation as required.11 in container is as stainless steel system, to carrying out attrition process and mirror finish is simple in its surface.
The image of taking with the filming apparatus in the thermally insulated container 8 must be recorded in the data recording equipment, adopts the data of final entry, makes the graphic information of furnace wall.Data recording equipment 22 can be accommodated in the thermally insulated container (with reference to Fig. 5) as the observing device of the present invention of above-mentioned (5).
Further more preferably as the observing device of the present invention of above-mentioned (4), in thermally insulated container, take in transmission over radio emitter 18, outside stove, dispose transmission over radio receiving apparatus 21 and data recording equipment 22 (with reference to Fig. 3 and Fig. 6).
To be transferred to transmission over radio receiving apparatus 21 from transmission over radio emitter 18 with the information that filming apparatus 8 is taken, be recorded in the data recording equipment 22.In data recording equipment 22, record record with treatment unit such as computer 30 in, if show photographic images, then can confirm observations when observing in the stove in that the furnace wall observation device is inserted into image display device 31.
The thermally insulated container that returns in 1000 ℃ the stove because the outside becomes high temperature, if without the time, can't take out internal data.Different therewith, adopt the observing device of the present invention of above-mentioned (4), after in stove, extracting the furnace wall observation device out, do not take out the operation and the time of view data owing to do not need to wait for this device cooling back, therefore, can confirm the situation of furnace wall rapidly.
And, the furnace wall observation device that takes out from the pit kiln coking chamber can be used at once the observation of next coking chamber.
For the transmission over radio of thermally insulated container outside stove in stove, can use and adopt electromagnetic transmission over radio, perhaps adopt the transmission over radio of light such as visible light or infrared rays.When carrying out transmission over radio,, as shown in Figure 6, the window 17 of transmission usefulness is set on the wall outside the stove of thermally insulated container 3.
On window 17, thermal glass is installed, when using hertzian wave, in order to prevent that invading photothermal coating from the outside does not use washing, and is carried out the coating of the such non-conducting material of silica-coating as transmission medium.
As shown in Figure 8, in transmission over radio, can adopt the digital radio transreceiver (27,28) of using the electric wave transmission of digital signals.Owing to what export from filming apparatus 8 is the mimic picture signal, therefore, converts this signal to numerary signal with A/D converter 26, this numerary signal is launched with digital radio emitter 27, with outer digital wireless receiver 28 receptions of stove.
The numerary signal that receives can convert simulating signal to by enough D/A converters 29, outputs to image display device 31, in perhaps direct form input processing device 30 grades with numerary signal.
When in thermally insulated container, disposing transmission over radio emitter 18, photographing information is transferred to the outside transmission over radio receiving apparatus 21, in its data logging data recording equipment 22 externally from thermally insulated container.
At this moment, as the observing device of the present invention of above-mentioned (6), positional information in the stove of filming apparatus (the shooting present position data 35 of horizontal direction in the stove) can also be recorded in the data recording equipment 22 simultaneously with photographing information.
This is because external data record device 22 is configured in outside the stove, therefore, can and be taken into the shooting present position data 35 of filming apparatus 8 from the present position data computation of the forcing machine 43 that loads filming apparatus 8.
Its result externally in the data recording equipment 22, can make the camera site of horizontal direction corresponding with photographed data in real time, under observation, can determine damage position in the stove and the position that will repair immediately.
Also can be with above-mentioned opposite, data recording equipment 22 and transmission over radio receiving apparatus 21 are set in thermally insulated container, often from the outside stove interpolation of thermally insulated container transmission over radio thermally insulated container is gone into constantly and stove in the shooting present position data 35 of horizontal direction, simultaneously the draining present position data 35 of horizontal direction in photographed data and the stove are recorded in the data recording equipment 22 in the thermally insulated container.
Transmission over radio emitter 18 and transmission over radio receiving apparatus 21 can adopt and have the transreceiver that transmits and receives two kinds of functions concurrently.
Thermally insulated container 3 as the observing device of the present invention of above-mentioned (7) (with reference to Fig. 1), preferably has sleeve pipe 5 of having filled the liquid 7 with heat absorption capacity and the thermal insulation material 4 that covers its outside.
Usually, liquid can the big liquid of selection unit's quality volumetric heat capacity amount.As obtaining and, preferably make water the easiliest as the optimal liquid of heat-sink material industrial.
When being inserted into thermally insulated container 3 in the High Temperature Furnaces Heating Apparatus,, therefore, can reduce to enter into inner heat by thermal insulation material 4 because the outside of thermally insulated container is covered by thermal insulation material 4.
Further, in the inboard of thermal insulation material 4,, therefore, invade inner heat and at first consume at this liquid 7 of raising, for example on the temperature of water owing to there is the sleeve pipe 5 of having filled liquid 7 with heat absorption capacity.
Because the thermal capacitance of water is big, the thermally insulated container temperature inside is risen slow down.And then, if water temperature reaches 100 ℃, seized a large amount of vaporization heat by boiling, therefore, thermally insulated container inside can be above 100 ℃.
Emit water vapour because water temperature reaches 100 ℃ when coming to life, therefore, the top at thermally insulated container 3 is provided with opening port, perhaps safety valve can be set.In observing device of the present invention, feature is not connect that the furnace wall observation that is used in stove is supplied with or the pipe arrangement of expel liquid.
The stove of pit kiln is wide to be generally about 400mm, and observing device of the present invention must be formed on this space and keep the rich size that can insert.When making water as heat absorption liquid, the sleeve pipe that holds water will make about shared wide of water on the stove cross direction respectively for about 40mm.
As the thermal insulation material 4 of thermally insulated container 3 peripheries, for example, can use ceramic beaverboard, the thickness of thermal insulation material 4 can be about 30mm.
When the outside dimension that makes the furnace wall observation device was L500mm * W300mm * H500mm, the internal space that holds the furnace wall observation device was about L380mm * W160mm * H300mm.
When the furnace wall observation device that will have this shape is inserted in the coking chamber 41 of pit kiln of 1000 ℃ of temperature in the stove, the temperature of internal space of holding the furnace wall observation device is along with inserting the back elapsed time, after 3 minutes being 25 ℃, was 40 ℃ after 5 minutes, was 55 ℃ after 7 minutes.Be contained on the common use temperature of various electronicss in the thermally insulated container and be limited to about 50 ℃, therefore, in High Temperature Furnaces Heating Apparatus, can be detained at least 5 minutes.
In the furnace wall observation of the pit kiln coking chamber that is undertaken by observing device of the present invention, for example, when lift-launch furnace wall observation device 1 of the present invention is measured on coking forcing machine 43, when the chassis 40 of coking forcing machine 43 moves in orbit, with 5~10 minutes intervals continuously and Jiao who carries out repeatedly finishing pyrogenous coking chamber operation of extruding, in this operation, carry out the furnace wall observation of a plurality of coking chambers.
Because by in coking chamber, inserting once, fluid temperature in the thermally insulated container just rises, and therefore, measures if directly be inserted into next coking chamber without the time, then the temperature of the liquid 7 in the thermally insulated container 3 rises gradually, and the time that can be detained in the stove will shorten.
As shown in Figure 7, in the bottom of thermally insulated container 3, be provided with the relief outlet 23 that is used to discharge internal liquid, finish furnace wall observation at every turn, the internal liquid that outflow temperature rises adds the low new liq of temperature, can prevent that thus the temperature of liquid from rising.When adding new liq, if supply with cold liquid and, also can reduce the temperature of thermally insulated container self from inlet 24 continuously from relief outlet 23 discharges.As a result, can guarantee each residence time in enough stoves of measuring.
When in thermally insulated container, disposing transmission over radio emitter 18, as shown in Figure 8, the temperature of mensuration thermally insulated container and the thermometer 36 of the fluid temperature in the sleeve pipe are set in the thermally insulated container, can the temperature of measuring be transferred to outside the stove by transmission over radio emitter 18.
Thus, can outside stove, grasp the temperature of present furnace wall observation device, prescribe a time limit near on managing, stop measuring, the furnace wall observation device is fetched into outside the stove, thus, can prevent the damage of the furnace wall observation device that abnormal high temperature causes in temperature.
Observing device of the present invention can pre-determine the observation place in the stove, also the furnace wall of this position can be taken with rest image.Thus, the situation of the position, furnace wall that the prediction damage can be taken place obtains with graphic form.
On the other hand, shown in the observing device of the present invention of above-mentioned (8), more preferably filming apparatus 8 is taken when the depth direction of stove moves, photographed data is recorded in the data recording equipment 22.
Filming apparatus 8 for example moves the stove depth direction, as shown in Figure 3, the furnace wall observation device 1 that will hold filming apparatus 8 is installed on the coking forcing machine 43 of pit kiln coking chamber 41, by the action of piston driver 46, carry out being inserted in the stove coking forcing machine 43 or the operation of extracting out with certain speed.
Follow shot device 8 when taking continuously, form that can animation is observed shooting results.
More preferably be, as the observing device of the present invention of above-mentioned (9), by in the depth direction follow shot device 8 of stove, taking, processing can be obtained the image of the wide region of stove depth direction with the form of a width of cloth rest image in conjunction with the photographed data that is recorded in the data recording equipment 22.
For example, the translational speed of coking forcing machine is 300mm/ second, when the rest image shooting interval of filming apparatus is 1/30 second, moves 10mm from taking width of cloth rest image filming apparatus in the time of taking next rest image.
Therefore, if making the coverage of the cross direction (depth direction of stove) of a width of cloth rest image is 10mm, merge the rest image of taking successively, just can on the whole length of mobile coking forcing machine, the form with successive one width of cloth rest image obtain the furnace wall surface image.
Perhaps, the coverage that also can make cross direction is 100mm, and the rest image shooting interval is to take in 1/3 second.In Figure 10, adjacent 8 width of cloth rest images are engaged at image bonding station 15, expression forms the furnace wall picture of the image 14 of wide region.This data processing can be carried out in data recording equipment 22.
Configuration transmission over radio emitter 18 in thermally insulated container, photographing information is being transferred to transmission over radio receiving apparatus 21 from thermally insulated container, with in its data logging data recording equipment 22 externally the time, positional information in the stove of filming apparatus (the shooting present position data 35 of horizontal direction in the stove) is recorded in the observing device of the present invention in the data recording equipment 22 simultaneously, filming apparatus 8 is taken when the stove depth direction moves, can be selected rest image according to positional information in the stove.
To take rest image with the 100mm spacing on cross direction below, this rest image is engaged, the situation of furnace wall image that is formed in the depth direction wide region of stove describes as an example.
For example the rest image of taking is transferred to outside data recording equipment successively with 1/30 second spacing.In the data recording equipment 22 outside stove, according to positional information in the stove, filming apparatus arrives the rest image of 100mm spacing at every turn and takes the position, selects the rest image that receives this moment.
Thus, the result can be produced on the interior furnace wall image of wide region of the depth direction of stove by to obtain rest image with the 100mm spacing and engage these rest images on cross direction.If adopt this method, for example change even carried the speed of travel of the coking forcing machine of thermally insulated container, also can be uniformly-spaced to obtain rest image.
Configuration transmission over radio receiving apparatus when being transferred to positional information in the stove the thermally insulated container outside stove, in thermally insulated container, can carry out and above-mentioned same data processing in thermally insulated container.
And, can carry out in the thermally insulated container and during the transmission over radio transreceiver of the outer both sides' of stove emission reception in configuration, positional information in the stove is transferred to thermally insulated container outside stove, in thermally insulated container, select rest image, can only the rest image transmission over radio of selecting be transmitted into outside the stove with certain interval.
Filming apparatus 8 when moving, is being taken the depth direction of stove, obtain rest image, engage these rest images, be produced in the observing device of the present invention of furnace wall image of wide region of depth direction of stove, can also take in the mode that produces repeating part at adjacent rest image to each other.
For example, if carry out the roughly shooting of 100mm spacing on cross direction, the size that makes the cross direction of each rest image is 150mm, then produces the repeating part of 50mm.In repeating part, owing to take the identical part in furnace wall is arranged, therefore, carry out images match by image and handle according to the furnace wall, can make two width of cloth images carry out correct position and be combined and make its unification.
If adopt this method, positional information has some skews in the stove of each rest image even take, and also can revise these skews automatically, makes the furnace wall image of wide region of the depth direction of correct stove.
And then, even under the situation that can not use positional information in the stove,, can enough images match handle the overlapping scope of determining image for the image sets that has the repeating part time series to obtain in the adjacent image, be connected to each other, make correct furnace wall image.
For example, under the situation of observing the pit kiln coking chamber, the furnace wall is because high temperature and luminous by take this luminous with filming apparatus, can be observed the furnace wall.
Like this, as filming apparatus, when using the CCD photographic camera usually, can make shutter speed is to take about 1/1000 second.If so fast shutter speed even the translational speed of coking forcing machine is 300mm/ second, also can access the clear image that does not have photographic camera color inequality.
As mentioned above, at the depth direction of stove,, the surface, furnace wall of whole length can be received on the width of cloth rest image by with running gear follow shot device.
On the other hand, on the short transverse of stove, be according to the distance of minute surface and filming apparatus, still, the scope of common 500~600mm becomes coverage.Therefore, on the short transverse of stove, once the scope that can take is limited.
On the other hand, for example, in the pit kiln coking chamber, the part of the damage especially severe of furnace wall refractory for example is limited near positions such as packing into the line of the high direction coal of stove.
Therefore, near pack into the position line of coal can be observed,, also enough useful data can be obtained even for example the range of observation of the high direction of stove is defined if observing device of the present invention is arranged on.Certainly, by a plurality of furnace wall observation devices are set, once just can observe the furnace wall in the coking forcing machine on short transverse at the wide region of the high direction of stove.
Observing device of the present invention owing to be shaped as small-sized and light weight, does not need to be provided with cooling tubing etc., therefore, the height that is installed on the forcing machine can be changed easily, and, the installation site that changes on each given each height is measured, and can obtain the furnace wall observation data of the whole height of stove.
In observing device of the present invention,, therefore, has supply unit 10 in thermally insulated container inside owing to can't supply with operating power from the outside in measuring.Filming apparatus 8 and data recording equipment 22, the operation power of transmission over radio emitter 18 by supplying with from this supply unit 10.As supply unit 10, can use drying battery, charging battery etc.
If use the battery that can't charge as supply unit 10, change battery at every turn, must open thermally insulated container.And even when using chargeable power supply as supply unit 10, when charging cable connection plug was positioned at thermally insulated container inside, each charging must be opened thermally insulated container.
Use chargeable power supply as supply unit, further as shown in Figure 7, possess charging cable connection plug 25, can not open thermally insulated container and charge, can improve operability by outside at thermally insulated container 3.
Charging cable connection plug 25 is covered its outsides by thermal insulation material lid 34 in inserting stove the time, can connect charging cable only with 34 dismountings of thermal insulation material lid when charging.
The embodiment that shows observing device of the present invention below.
(embodiment)
Purpose based on the surface, furnace wall of observing the pit kiln coking chamber adopts furnace wall observation device shown in Figure 1.The physical dimension of furnace wall observation device 1 is: high 500mm, wide 300mm, long 500mm, gross weight is about 50kg.
As the thermally insulated container 3 of furnace wall observation device, use and covered the thermally insulated container of ceramic beaverboard as thermal insulation material 4 in periphery.The thickness of thermal insulation material is 30mm.In the inboard of thermal insulation material, dispose the sleeve pipe of stainless steel.In sleeve pipe, fill and amount to 30 liters water 7.In the part of thermally insulated container 3 in the face of the furnace wall, the thickness of water layer is 40mm.
In thermally insulated container inside, configuration is as the CCD photographic camera of filming apparatus 8.The picture signal of taking with filming apparatus is transferred to outside the stove by transmission over radio emitter 18.On thermally insulated container and thermal insulation material, viewing window 16 and transmission window 17 are set, the silica glass that has carried out metal evaporation is installed on viewing window.In addition, as supply unit 10, the configuration charging battery is as to filming apparatus, transmission over radio emitter and the supply power of controlling their control device.
In the place ahead of thermally insulated container, as shown in Figure 1, configuration minute surface 2a and 2b.Minute surface vertically is the short transverse of stove, and two minute surface 2a and 2b and furnace wall 42 are miter angle, can photograph furnace wall, left and right sides 42a and 42b in the visual field of filming apparatus 8 simultaneously.By the configuration of this minute surface, the visual field 13a of filming apparatus and 13b long side length on each furnace wall, the left and right sides becomes 600mm, and short brink length becomes 200mm.
Minute surface uses the surface of container 11 that inside is held the stainless-steel sheet system of water coolant 6 to carry out mirror ultrafinish and gets minute surface.Container 11 is the long shape of cross section orthogonal as shown in Figure 2, and it is minute surface that the two sides is arranged in 4 the outside, and remaining two sides is by thermal insulation material 12 adiabatic structures.
Furnace wall observation device and minute surface are installed on the forcing machine 43.The gross weight of furnace wall observation device is about 50kg, is the comparison light weight, and then, owing to do not need to dispose cooling water pipe and signal cable, therefore, can easily be installed in the optional position of the short transverse of extruding piston 44.
In the present embodiment, as shown in Figure 3,, adopt bracing or strutting arrangement 45 to install, perhaps, be installed in the position of the furnace wall observation device 1 ' on the piston crossbeam 47 in the position of the furnace wall observation device 1 of extruding piston 44 back.Like this, at each height,, just can obtain the furnace wall observation data of wide region by carrying out furnace wall observation successively.
Transmission over radio adopts the radio communication of the electric wave that uses numerary signal.Convert the output of filming apparatus and the output of measuring the thermometer 36 of temperature in the determination unit to numerary signal with A/D converter 26, deliver to numerary signal transmitting set 27.Numerary signal transmitting set 27 plays a role as transmission over radio emitter 18, and wireless signal transmission 19 is transferred to the outer transmission over radio receiving apparatus 21 of stove.
In thermally insulated container, the part of passing through at electric wave is provided with transmission window 17, and the silica glass of silica-coating has been implemented in configuration.This silica-coating is blocked the radiant heat from stove, and owing to be not washing, does not therefore hinder the transmission of electric wave.
Outside stove, as transmission over radio receiving apparatus 21, dispose numerary signal wireless receiver 28, as data recording equipment 22, dispose treatment unit 30 and image display device 31.The digital data transmission that receives with numerary signal wireless receiver 28 arrives D/A converter 29 and treatment unit 30.
The data of having delivered to treatment unit 30 are recorded in the computer, simultaneously, are processed to form simulating signal graphical information, that export from D/A converter 29 of taking the easy decomposition of signal and are sent to image display device 31.
In data recording equipment 22, owing to also transmitted the shooting present position data of obtaining based on the present position data of extruding piston 44 35, therefore, these data also are transferred to treatment unit 30 and image display device 31.
In image display device 31, be arranged in the photographing information that each is taken constantly according to taking present position data 35, can be created on a width of cloth rest image of the whole length of coking chamber depth direction, can determine the position that the furnace wall damage takes place.
Specifically, be accompanied by moving of forcing machine 43, take present position data 35 every increase 150mm, just the rest image with transmission reads treatment unit 30.Because the length of the stove cross direction (short brink) of rest image is 200mm, so adjacent image has the lap of 50mm.
Adopt this lap to carry out images match and handle, can finely tune the overlapping of image.Like this, can be formed in a width of cloth rest image of the whole length of coking chamber depth direction.
The result who represents an example observation furnace wall at Fig. 9.(a) of Fig. 9 is in the visual field 9 of filming apparatus integral body, reflects image and the image that reflects at the furnace wall of minute surface 2b 42b at the furnace wall of minute surface 2a 42a.In any one image, can both discern the puzzle joint 49 of brick 48 clearly.
Fig. 9 (b) observes the image that the position of damage takes place on the furnace wall.Except normal puzzle joint 49, can be observed puzzle joint cracking 50.And, can observe furnace wall longitudinal slit 51.In the image shown in (c) of Fig. 9, the carbon that also can be observed the furnace wall adheres to 52.
And then, by in conjunction with the rest image that obtains continuously that moves of following forcing machine 43, can obtain the furnace wall image of the wide region on the depth direction of stove.
At Figure 10, be illustrated in image bonding station 15 and engage the furnace wall picture that eight adjacent width of cloth rest images have been made wide region image 14.In the image of wide region, determine damage location easily, and can grasp whole degree of impairment at a glance, therefore, be useful carrying out in body of heater diagnosis and the management.
In mensuration, to data recording equipment 22 transmission data, therefore, need after measuring end, not open thermally insulated container successively, can increase substantially the operability of mensuration.And, in mensuration,, can correctly determine the occurrence positions of this damage with catching the furnace wall damage in real time, therefore, can not determine the repairing plan of this coking chamber with incuring loss through delay.
After the furnace wall observation of finishing a coking chamber, before then carrying out the furnace wall observation of next coking chamber, open the relief outlet 23 of thermally insulated container bottom, in the water coolant 7 that outflow temperature rises, inject the water of normal temperature from the inlet 24 on top.At the water that injects 15 liters, reduce after the temperature of thermally insulated container 3 relief outlet 23 of closing the thermally insulated container bottom, the middle water of filling in thermally insulated container.
Like this, owing to, therefore, when carrying out the furnace wall observation of coking chamber continuously, also can guarantee each 5 minutes or above minute the water temperature in thermally insulated container and the thermally insulated container is reduced to such an extent that measure after abundant next time at every turn.
As the charging battery that the supply unit in the determinator 10 uses, have can 10 wide mensuration of coking chamber stove of METHOD FOR CONTINUOUS DETERMINATION capacity.In when charging and since can be connected charging cable in the charging cable connection plug 25 that is configured in the thermally insulated container outside and charge, therefore, need not open thermally insulated container in order to charge, can charge with good operability.
(2) then, according to Fig. 3, Fig. 8 and Figure 11~23 explanations furnace wall shape measuring device of the present invention (below be sometimes referred to as " determinator of the present invention ").
As shown in figure 11, furnace wall shape measuring device 61 of the present invention, portion accommodates beam irradiation device 62a and 62b and filming apparatus 8 within it.Furnace wall shape measuring device 61 is near furnace wall 42a and 42b configuration.When in the pit kiln coking chamber, inserting furnace wall shape measuring device 61,, therefore, be inserted into the wide central authorities of coking chamber, dispose near the both sides furnace wall because the distance between the relative furnace wall (42a, 42b) is narrow.
From beam irradiation device 62a and 62b to furnace wall 42a and 42b from oblique direction light beam 63a and 63b.In Figure 11, with angle θ illumination beam.Furnace wall lip-deep light beam irradiates partial reflection light beam is luminous, forms luminous point 64a and 64b.
Filming apparatus 8 is based on trying one's best from comprising that with the vertical direction shooting in furnace wall the purpose on the surface, furnace wall of this beam reflection light is configured.Can use its controller of camera etc. of CCD photographic camera and control as filming apparatus 8.As Figure 11 and shown in Figure 12, can be with visual field direction and the furnace wall 42a and the 42b configured in parallel of filming apparatus 8.
Like this, at the visual field of filming apparatus 8 direction configuration minute surface, the angle of minute surface will be adjusted to when the position of filming apparatus 8 is observed, and the image on surface, furnace wall reflects on minute surface.
As shown in figure 11, be 45 degree if make the angle of minute surface 2a and 2b and furnace wall 42a and 42b usually, owing to can obtain to see the image on surface, furnace wall from vertical direction, therefore preferred.Certainly, when vergence direction was seen the furnace wall, when being able to clearly to observe surface, furnace wall concavo-convex, the angle that can make minute surface and furnace wall was outside 45 degree.
In the measuring shape in stove, usually, make the distance of filming apparatus and minute surface certain.The distance of filming apparatus and minute surface is long more, can prolong the effective minute surface length with the furnace wall parallel direction more, can enlarge the scope (length of long side) in the filming apparatus visual field 13 of observing minute surface.
On the other hand, for the vertical direction in furnace wall, i.e. the limited minute surface width of cross direction because the interval of furnace wall is narrow, therefore, can't enlarge, and can not enlarge the scope (length of short brink) in the filming apparatus visual field 13.
When observing the pit kiln coking chamber, be about 500~600mm if make the long side length in the filming apparatus visual field 13 on surface, furnace wall, adopt common CCD photographic camera, just can carry out damage is detected the observation of enough about 1mm of space resolution capability.The short brink length in the photographs device visual field, surface, furnace wall 13 is about 150~200mm from vertical direction observation furnace wall the time.
As shown in figure 13, light beam 63 is from oblique direction from 62 pairs of furnace walls of beam irradiation device surface 66b.In Figure 13, shine with angle θ.Therefore, if the distance between furnace wall shape measuring device 61 (beam irradiation device 62) and the furnace wall only changes Δ x, the position of the point (luminous point) that light beam 63 and surface, furnace wall 66b intersect fades to 64b from 64a, and the position of beam reflection light only changes Δ y.
Filming apparatus 8 is owing to take the surface, furnace wall 66 that comprises beam reflection light, therefore, the variable in distance between furnace wall shape measuring device 61 and the furnace wall 42, i.e. the change in location that furnace wall distortion can be used as the beam reflection light in the photographic images obtains.
Therefore, adopt the image that obtains by filming apparatus 8, can estimate the situation of furnace wall two dimension wide region, can estimate specific position quantitatively simultaneously, i.e. the situation that consumes at beam irradiation position.
Can form the light beam of point-like from the light beam 63 of beam irradiation device 62 irradiations.Like this, some place in the furnace wall, can estimate and furnace wall shape measuring device 61 between distance.
On the other hand,,, can shine in the time of on shining the furnace wall as (a) of Figure 14 with (b) from the light beam 63 of beam irradiation device 62 irradiation in the mode that reflected light becomes Line of light 65.When using the such pointolite of laser, can form the light beam that produces this Line of light 65 only at the barrel surface lens of single shaft direction extension point light by configuration before light source as beam light source.
For example, shown in Figure 14 (c), under the situation that has ditch shape loss position 67 on the surface, furnace wall 66, to these surface, furnace wall 66 illumination beams 63, when producing Line of light 65, corresponding with loss position 67, shown in Figure 14 (b), can on Line of light 65, see skew 68.
If the degree of depth of loss position 67 is Δ x, the relation of the y-shaped one-tenth Δ of the size delta y=Δ x/tan θ of skew 68.Just can in the linear parts that produces linear reflection light, quantitatively grasp the concavo-convex of surface thus.
In the coking chamber 41 of the long pit kiln of depth,, must be difficult with the common maintenance in interval of furnace wall shape measuring device 61 and surface, furnace wall (furnace wall reference plane) 66 when an end inserts furnace wall shape measuring device 61.Here so-called furnace wall reference plane is meant the reference plane when surface, furnace wall 66 does not have loss, can think that the furnace wall waste is 0 surface, furnace wall.Therefore, when making light beam 63 for the point-like light beam, it is certain can making the distance between surface 66, the furnace wall on the beam reflected point 64 and furnace wall shape measuring device 61, still, determines that the absolute value of furnace wall waste is had any problem.
On the other hand, in surface, furnace wall 66, where be intact part, where be loss generation part, just can probably know by observing the image of taking with filming apparatus 8.
Determinator of the present invention is owing to can carry out the situation of the wide region by image evaluation furnace wall two dimension and the loss situation of quantitative evaluation specific position simultaneously, therefore, pass through illumination beam, producing the linear reflection light time, in linear parts, can comprise furnace wall intact part and loss generation part simultaneously.
If carry out such mensuration, in the scope of Line of light 65, can determine the relative concavo-convex amount in the surface, furnace wall 66.Therefore, in determinator of the present invention, even for example can not determine the distance between furnace wall shape measuring device 61 and the furnace wall reference plane, also can determine intact part and loss generating unit divide between relative depth poor, and the waste in the part takes place in definite loss.
Here will comprise that the face that shines on the furnace wall and produce the light beam 63 of Line of light 65 is called the light beam face.The position of Line of light 65 is consistent with the interlacing line on light beam face and surface, furnace wall 66 certainly.
And, as (b) of Figure 14 with (c), in the light beam 63 that produces Line of light 65, with the point-like light beam of light beam cross direction central authorities during as central light beam 69, be the face that comprises central light beam 69,, will be called the central light beam vertical surface here with surface, furnace wall 66 vertical faces.
Parallel with the central light beam vertical surface at the light beam face, when promptly consistent, even exist concavo-convexly on surface, furnace wall 66, reflected light also keeps straight line, even observe reflected light, also can't estimate the waste of furnace wall.
Mutually at right angles the time, can detect the concavo-convex of surface, furnace wall 66 at light beam face and central light beam vertical surface most effectively, the change in location of Line of light 65 promptly is offset 68.As (b) of Figure 14 with in the example (c), light beam face and central light beam vertical surface are rectangular mutually.
The line of the level crossing that plane that the furnace wall constitutes and minute surface constitute forms intersection 70 here.In the example shown in (b) of Figure 12, intersection 70 forms the line of vertical direction.
Shown in Figure 12 (a), consider beam irradiation device 62a and 62b are set near filming apparatus 8, light beam 63a and 63b are not reflected to minute surface 2a and 2b, but the situation of direct irradiation on surface, furnace wall 66.
At this moment, if at this moment the direction of Line of light 65 and intersection 70 quadratures just are equivalent to the above-mentioned light beam face situation parallel with the central light beam vertical surface, can't estimate the consumption of furnace wall.
Can effectively detect concavo-convex scheme in order to form, promptly form the mutually rectangular degree scheme of light beam face and central light beam vertical surface, equally, shown in Figure 12 (a), can make the direction of the Line of light 65 that is radiated at the furnace wall substantially parallel with the intersection 70 of above-mentioned wall and minute surface.
Below, as (a) of Figure 15 with (b), consider to reflex to minute surface 2b, and light beam 63 is shone the situation on surface, furnace wall 66 from beam irradiation device 62.For reflex to minute surface 2b and to surface, furnace wall 66 from the oblique direction light beam, shown in Figure 15 (a), beam irradiation device 62 and filming apparatus 8 must be left configuration.
The direction of leaving is the direction parallel with the intersection 70 of above-mentioned wall and minute surface.At this moment, if see the beam irradiation device 62 that reflects on minute surface 2b from the position on surface, furnace wall 66, beam irradiation device 62 can be seen in the 62a position among (a) of Figure 15.Adopt such configuration, at this moment suitable when parallel with the central light beam vertical surface if the direction of Line of light 65 is parallel with intersection 70 with above-mentioned light beam face, can't estimate the waste of furnace wall.
Can to detect concavo-convex scheme effectively in order forming, promptly to form light beam face and central light beam vertical surface rectangular scheme mutually, shown in Figure 15 (a), can make the direction of the Line of light 65 that shines the furnace wall and the intersection 70 basic quadratures of furnace wall and minute surface.
As beam irradiation device 62, preferably use laser irradiation device (LASER Light Source).This is because if be LASER Light Source, can produce choice refreshments shape light and strong light beam.In order to form the light beam that is radiated at the furnace wall and becomes linear reflection light, use the barrel surface lens, a light only can be expanded on the single shaft direction.The angle of expansion, promptly the length of the linear reflection light on the face of furnace wall is determined by the focal length of barrel surface lens.
Inside in the high temperature carbonization chamber, surface, furnace wall 66 is luminous at red area because of luminous.Particularly, adhere to the part 52 of carbon, burning forms high temperature, and red luminous intensity is strong.If optical maser wavelength, is defeated by the luminous on surface, furnace wall at red area, beam reflection light is difficult to detect.
As the miniature laser light source that can carry in thermally insulated container, what use at present is red laser diode, and wavelength is 633nm or 670nm.It has the wavelength region identical with the luminous on surface, furnace wall 66, at the such high-temperature area of the part 52 of adhering to carbon, can't fully detect the reflected light of light beam sometimes.
In determinator of the present invention, preferred light beam irradiation apparatus 62 is the laser light irradiating unit of illumination wavelength 550nm or following light, and filming apparatus 8 is colored filming apparatus.If make wavelength at 550nm or following, because different with the long zone of the self luminous high-amplitude wave on surface, furnace wall 66, therefore, in the coloured image of taking, Line of light is emphasized to show.
By adopting picture processing to emphasize to take out wavelength 550nm or following composition, Line of light 65 can be made clear more from the image of taking.
In the determinator of the present invention when the image that the luminous of taking by the high temperature furnace wall produces, self luminous intensity changes according to the temperature of furnace wall.If the furnace wall temperature height, the furnace wall brightness height that luminous produces, if furnace wall temperature is low, furnace wall low lightness.The part of particularly adhering to carbon, owing to carbon burning becomes high temperature, the brightness height of this part.
At filming apparatus 8, according to the brightness on surface, furnace wall,, perhaps regulate the time shutter by regulating the aperture of optical system, can access best furnace wall surface image.Usually, by the automatic exposure function of filming apparatus 8, can obtain optimal images automatically.
On the other hand, if the intensity of the light beam 63 by beam irradiation device 62 irradiation is certain, under the obviously high situation of furnace wall temperature, the luminous on surface, furnace wall forms higher brightness than beam reflection light, the exposure of filming apparatus 8 is definite by the brightness on surface, furnace wall 66, therefore, and the relative deepening of beam reflection light, can't fully capture beam reflection light, also just can't determine the position of beam reflection light.
Otherwise, when furnace wall temperature is low since with the consistent exposure of adjusting filming apparatus of the furnace wall self luminous low-light level in surface, therefore, beam reflection light is strong excessively, produces halation, can't correctly determine the position of beam reflection light.
In determinator of the present invention, owing to have the device of the furnace wall surface luminous intensity of measuring illumination beam, therefore,, can adjust from the intensity of the light beam 63 of beam irradiation device 62 irradiations according to the luminous intensity of this mensuration, also just can address this problem.
When furnace wall surface luminous intensity is high, strengthen the intensity of light beam 63, make the position of correctly catching beam reflection light become possibility by filming apparatus 8.And when furnace wall surface luminous intensity is low, weaken the intensity of light beam 63, can prevent the halation of beam reflection light.
The electric power of supplying with to beam irradiation device 62 is to supply with from the supply unit 10 that is accommodated in the thermally insulated container.In order to prolong the duration of service of charging next time that is charged to from supply unit 10, the electric power consumption of beam irradiation device 62 is few more good more.
If as determinator of the present invention, adjust the intensity of light beam, can reduce the electric power consumption of beam irradiation device 62 according to furnace wall luminous intensity.
When measuring the luminous intensity on surface, furnace wall, can directly use the evaluation result of the automatic exposure unit of filming apparatus 8.Perhaps, as shown in figure 23, the device of quantorecorder 71 as the mensuration light quantity outside the filming apparatus 8 can be set.And, also can measure the temperature on surface, furnace wall 66, infer luminous intensity according to the blackbody radiation formula of Planck (プ ラ ソ Network) from temperature.
Because determinator of the present invention moves in stove, as temperature measuring apparatus, the preferred radiation thermometer that uses.And then when measuring luminous intensity,, also can only take out light beam wavelength with irradiation and be the light intensity of the wavelength region at center and measure though can measure the average luminous intensity of the whole wavelength of visible light.
When measuring luminous intensity, in the surface, furnace wall of illumination beam, can also measure the average luminous intensity in the filming apparatus visual field of taking with filming apparatus 8 13.And, be limited to the zone of shining the light beam in the filming apparatus visual field 13, also can measure light intensity.
In determinator of the present invention, for the linear parts of furnace wall, can estimate the concavo-convex amount on surface, furnace wall quantitatively, the furnace wall integral status that comprises the two dimension of this linear parts can be grasped with the image form simultaneously.Its result for example, when obtaining to produce the data of expansion lamination on the surface, furnace wall, can distinguish this expansion lamination clearly according to image and be caused by brick wall face distortion itself, still is to cause by adhering to carbon.
Therefore, can establish correct repairing plan according to the measuring shape result.Specifically,, be blown into air and burn and remove,, according to circumstances, establish large-scale repair operation plan if the wall body distortion takes place if carbon adheres to.
As the direction that is provided with of minute surface, shown in Figure 12 (b), the intersection 70 that can make furnace wall and minute surface and the high direction of stove are that the depth direction of stove meets at right angles.The depth direction of stove is the direction that moves furnace wall shape measuring device 61 when observing furnace wall 42a and 42b, by observing when moving, can accumulate the furnace wall shape measuring result of stove depth direction.
Therefore, be and the rectangular direction of depth direction (travel direction) of stove to take the photographing information on surface, furnace wall to greatest extent by the intersection that makes furnace wall and minute surface.
In determinator of the present invention, as Figure 11 and Figure 16~shown in Figure 180, be the electronics of representative with beam irradiation device 62 or filming apparatus 8, be accommodated in the thermally insulated container 3, minute surface 2 or 2a and 2b are configured in the outside of thermally insulated container 3.For thermally insulated container 3, outside stove, do not supply with water coolant, and, do not connect power supply wiring and signal wiring yet.
Therefore, can will be arranged on furnace wall shape measuring device 61 light weights and miniaturization in the stove, can be in being inserted into stove and the works that moves, for example loading and unloading (with reference to Fig. 3) easily on the coking forcing machine 43 of pit kiln coking chamber 41.
As Figure 16 and shown in Figure 17, the surface of thermally insulated container 3 is covered by thermal insulation material 4, therefore, if at short notice, can be trapped in and also normally move inner electronics in the High Temperature Furnaces Heating Apparatus.
Thermally insulated container 3, owing to can therefore, can guarantee that the coking forcing machine 43 that will furnace wall shape measuring device 61 be installed is inserted in the stove in 41 inner the delays 3 minutes of coking chamber of pit kiln, on the whole length of the depth direction of stove, observe the furnace wall, and be retracted to the outer MIN time of stove.
Thermal insulation material 4 as covering thermally insulated container 3 for example, can use ceramic beaverboard or calcium silicate board etc.
In determinator of the present invention, owing to, the viewing window 16 that guarantees the thermally insulated container 3 in the filming apparatus visual field can be retained in minimal size at the outside of thermally insulated container 3 configuration minute surface 2 or 2a and 2b.
Be accommodated in prism in the case and guaranteeing in the prior art in the wide visual field, must enlarge the size that is arranged on the viewing window on the case, when using thermally insulated container, exist the radiant heat that enters in the container from viewing window to cause the problem that temperature sharply rises in the container, but as determinator of the present invention, minute surface is configured in the outside of thermally insulated container, as a result, can dwindle viewing window 16, therefore, the radiant heat of from then on invading is reduced to minimum, can prevent that the temperature in the thermally insulated container from rising.
Thermal glasses such as silica glass are installed on viewing window 16.Thermal glass preferably has the glass of reflection next photothermal function from the outside by means such as metal evaporations.
In determinator of the present invention, can shown in Figure 16 (a), adopt a minute surface, observe the furnace wall 42a of a side.At this moment, beam irradiation device 62 is also only to being positioned on the furnace wall 42a illumination beam 63 of observing a side.
In addition, preferably as shown in figure 17, possess a plurality of beam irradiation device 62a and 62b in thermally insulated container, illumination beam 63a and 63b on relative furnace wall surface 66a and 66b mirror the face of the beam reflection light that comprises relative furnace wall 42a and 42b by different two minute surface 2a of angle and 2b.
In Figure 12 and example shown in Figure 17, the 1st minute surface 2a mirrors the surface of the 1st furnace wall 42a, and the 2nd minute surface 2b mirrors the surface of the 2nd furnace wall 42b, can take the two simultaneously by single filming apparatus 8.
Thus, adopt the furnace wall shape measuring device 61 take in a filming apparatus 8 and two beam irradiation device 62a and 6b, move once, just can measure the furnace wall surface shape of the left and right sides by depth direction at stove.
In addition, move, can compare furnace wall, the left and right sides simultaneously by above-mentioned.And then, owing to can observe furnace wall, the left and right sides with a filming apparatus 8, therefore, compare with the situation of in thermally insulated container, taking in two filming apparatus, can reduce the port area of the viewing window 16 of thermally insulated container, and reduce to cause in the radiant heat intrusion thermally insulated container ratio of temperature rising.
On forcing machine that furnace wall shape measuring device is installed in pit kiln etc., when an end of pit kiln coking chamber inserts the mensuration of carrying out in the coking chamber, be difficult to furnace wall shape measuring device correctly is configured in the center of the furnace wall reference plane of both sides, be offset from the center.
Therefore, only to a side furnace wall illumination beam time, obtaining actual surface, furnace wall, with the furnace wall reference plane absolute value of how many losses to be arranged be difficult.
Adopt two beam irradiation devices and two minute surfaces to measure simultaneously in the determinator of the present invention of furnace wall surface shape of the left and right sides, can measure the distance at mensuration position on the surface, furnace wall of the furnace wall shape measuring device and the left and right sides simultaneously.Can calculate the distance between the mensuration position on surface, furnace wall, the left and right sides by this measured value.
Owing to known the distance between the furnace wall of the initial stage that loss does not take place,, can calculate the total waste of the left and right sides therefore based on this measured value.If the look-out station of the left and right sides is the complete position that can't observe partial loss at least, the loss equalization about can thinking is carried out, and therefore, half of the total waste measured can be estimated as the furnace wall waste at complete position.
By observing Line of light 65, can detect Line of light and produce the poor of the relative loss factor amount between the complete position and local loss part in the scope, as mentioned above, can also estimate the furnace wall waste at complete position, therefore, adopt these values, can also infer the waste absolute value of local loss part.
In determinator of the present invention, because minute surface is configured in the outside of thermally insulated container 3, therefore, minute surface directly is exposed to the high-temperature atmosphere in the stove.In determinator of the present invention, as shown in figure 17, the surface that makes inside take in the container 11 of water coolant 6 becomes minute surface 2a and 2b.
The time that determinator 61 of the present invention is trapped in the High Temperature Furnaces Heating Apparatus is the short period of time, if in such time, the temperature of the water coolant 6 in the container 11 rises and seethes with excitement, boiling cooling vessel 11, the temperature of container 11 can be remained on the boiling point (100 ℃) of water coolant, when can remain on the optical property of minute surface 2a that vessel surface forms and 2b for a long time, can keep the planeness of minute surface 2a and 2 for a long time equally.
In determinator of the present invention, do not need outside stove, to supply with the water coolant that is used to cool off minute surface 2a and 2b, also needn't use the primary heater unit of preheating minute surface, therefore, can loading and unloading simply on running gears such as coking forcing machine.
Inside holds the container 11 of water coolant 6, and is microscler for the cross section orthogonal as Figure 12 and shown in Figure 17, is minute surface with the two sides in four outsides, for remaining two sides, as required, available thermal insulation material 12 thermal insulation.
11 in container is as steel, and the stainless steel plate that Pasting has carried out mirror finish on will be as the two sides of minute surface constitutes.In addition, also can container 11 as stainless steel system, mirror finish is carried out on its surface.
The photologging of taking with filming apparatus 8 in the thermally insulated container finally must adopt the graphic information of the data creating furnace wall of record in data recording equipment 22.Data recording equipment 22 can be accommodated in the thermally insulated container (with reference to Figure 16 and Figure 17).
On the other hand, more preferably in thermally insulated container, take in transmission over radio emitter 18, outside stove, transmission over radio receiving apparatus 21 and data recording equipment 22 are set.
To be transmitted into the transmission over radio receiving apparatus 21 that is arranged on outside the stove from transmission over radio emitter 18 with the information that filming apparatus 8 is taken, be recorded in the data recording equipment 22.In data recording equipment 22, if be input to record with treatment unit such as computer 30 in, show photographic images with image display device 31, just can furnace wall shape measuring device is inserted into observe in the stove in the affirmation observations.
The thermally insulated container 3 that returns in 1000 ℃ the stove, because the outside becomes high temperature, therefore, if spended time not just can't take out internal data.Relative therewith, if adopt above-mentioned emission to receive system, just do not need in stove, to extract furnace wall shape measuring device 61 out, wait for the device cooling, take out the time and the operation of view data, therefore, can confirm the shape of furnace wall rapidly.And, can will be used for the observation of next coking chamber from the inner furnace wall shape measuring device 61 that takes out of coking chamber immediately.
For the transmission over radio that the thermally insulated container in stove carries out, can adopt the transmission over radio of using electromagnetic wireless transmission or using light such as visible light or infrared light outside stove.
Under the situation of carrying out transmission over radio, the window 17 of transmission usefulness is set on the wall in the stove outside at thermally insulated container.On window 17, thermal glass is installed, is being used under the situation of hertzian wave as transmission medium,, do not use metallic membrane to apply, and use the so non-conductive coating of silica-coating as the coating that is used to prevent from the photothermal intrusion of outside.
As shown in Figure 8, transmission over radio can be used by the numerary signal wireless transmission receiving apparatus (27,28) of electric wave with digital data transmission.From filming apparatus 8 output mimic picture signals, therefore, this signal transition is become numerary signal with A/D interpreter 26, this numerary signal with 27 emissions of numerary signal transmitting set, is received with the numerary signal wireless receiver outside the stove 28.
The numerary signal that receives converts simulating signal to D/A converter 29, outputs to image display device 31, perhaps directly numerary signal is input in treatment unit 30 grades.
When in thermally insulated container, disposing transmission over radio emitter 18, filming apparatus is delivered to outside transmission over radio receiving apparatus 21 from thermally insulated container, in its data logging data recording equipment 22 externally.At this moment, also can simultaneously positional information in the stove of filming apparatus (the shooting present position data 35 of horizontal direction in the stove) be recorded in the data recording equipment 22 with photographing information.
The shooting present position data 35 of filming apparatus 8 therefore can be calculated and be taken into to outside data recording equipment 22 owing to be configured in outside the stove, from the present position data of the forcing machine 43 that is equipped with filming apparatus 8.
Its result in the data recording equipment 22 externally, can make the camera site of horizontal direction corresponding with photographed data in real time, under observation, can determine the position that damage position must be repaired in the stove immediately.
With above-mentioned different, data recording equipment 22 and transmission over radio receiving apparatus 21 are set in thermally insulated container, for thermally insulated container, often send the shooting present position data 35 of horizontal direction in the stove interpolation angle of incidence of thermally insulated container and the stove from external wireless, simultaneously, the shooting present position data 35 of horizontal direction in photographed data and the stove are recorded in the data recording equipment 22 in the thermally insulated container.
Transmission over radio emitter 18 and transmission over radio receiving apparatus 21 can use and have the transreceiver that transmits and receives both sides' function concurrently.
Thermally insulated container 3 preferably has sleeve pipe 5 of having filled the liquid 7 with heat absorption capacity and the container that covers the thermal insulation material 4 in its outside as Figure 11 and shown in Figure 19.
In general, liquid can selection unit's quality, the big liquid of thermal capacitance of volume.As in the easiest industrial acquisition and be suitable as the liquid of heat-sink material most, preferably water.
Because the outside of thermally insulated container 3 is covered by thermal insulation material 4, therefore, when being inserted into thermally insulated container 3 in the High Temperature Furnaces Heating Apparatus,, can dwindle invading inner heat by thermal insulation material 4.
And then, in the inboard of thermal insulation material 4, owing to exist the sleeve pipe 5 of having filled liquid 7, therefore, invade inner heat and at first consume and improving this liquid for example on the temperature of water with heat absorption capacity.Because the thermal capacitance of water is big, therefore, can make the rising of thermally insulated container temperature inside laten slow.
And then, if water temperature reaches 100 ℃, captured a large amount of vaporization heat by boiling, therefore, the thermally insulated container temperature inside is no more than 100 ℃.Discharge water vapour because water temperature reaches 100 ℃ when coming to life, therefore, opening can be set or safety valve is set on the top of thermally insulated container 3.
In determinator of the present invention, has the feature that does not connect the pipe arrangement that is used to supply with expel liquid in the furnace wall shape measuring in stove.
The stove of pit kiln coking chamber 41 is wide to be generally about 400mm, and determinator of the present invention must be formed on the size of allowing some leeway and can insert in this space.When making water as heat absorption liquid, the sleeve pipe that holds water is respectively about 40mm about shared wide of water on the stove cross direction.
As the thermal insulation material 4 of thermally insulated container periphery, for example, use ceramic beaverboard, the thickness that makes thermal insulation material 4 is about 30mm.When the outside dimension that makes furnace wall shape measuring device was L500mm * W300mm * H500mm, the internal space that holds furnace wall shape measuring device was about L380mm * W160mm * H300mm.
When the determinator of the present invention with this shape is inserted in the coking chamber 41 of pit kiln of 1000 ℃ of temperature in the stove, the temperature of internal space of holding furnace wall shape measuring device is along with inserting the back elapsed time, after 3 minutes being 25 ℃, was 40 ℃ after 5 minutes, was 55 ℃ after 7 minutes.The normally used upper temperature limit of various electronicss that is contained in the thermally insulated container is about 50 ℃, therefore, can be detained at least 5 minutes in High Temperature Furnaces Heating Apparatus.
In the furnace wall shape measuring of the pit kiln coking chamber that adopts determinator of the present invention to carry out, for example, when lift-launch furnace wall of the present invention determinator 61 is measured on coking forcing machine 43, when the chassis 40 of coking forcing machine 43 moves in orbit, with 5~10 minutes intervals continuously and Jiao who carries out repeatedly finishing pyrogenous coking chamber operation of extruding, meanwhile, carry out the furnace wall shape measuring of a plurality of coking chambers.
By inserting in coking chamber once, the fluid temperature in the thermally insulated container rises, and therefore, if directly be inserted into next coking chamber without the time, the temperature of the liquid 7 in the thermally insulated container rises gradually, and the time that can be detained in the stove will shorten.
As shown in figure 19, in the bottom of thermally insulated container 3, be provided for discharging the relief outlet 23 of internal liquid, finish furnace wall shape measuring at every turn, the internal liquid that outflow temperature rises adds the low new liq of temperature, can prevent that thus the temperature of liquid from rising.
When adding new liq, if supply with cold liquid and, also can reduce the temperature of thermally insulated container self from inlet 24 continuously from relief outlet 23 discharges.As a result, can guarantee to have the residence time in enough stoves at every turn.
When in thermally insulated container, disposing transmission over radio emitter 18, as shown in Figure 8, the temperature of mensuration thermally insulated container or the thermometer 36 of the fluid temperature in the sleeve pipe are set in thermally insulated container, can the temperature of measuring be transferred to outside the stove by transmission over radio emitter 18.
Thus, can grasp the internal temperature of present furnace wall shape measuring device outside stove, prescribe a time limit near on managing in temperature, stop measuring, furnace wall shape measuring device is fetched into outside the stove, the damage of the furnace wall observation device that abnormal high temperature can be caused prevents trouble before it happens.
Determinator of the present invention can pre-determine the observation place in the stove, and the furnace wall of this position is taken with rest image.Thus, the situation of the position, furnace wall that the prediction damage can be taken place obtains with graphic form.
And, more preferably filming apparatus 8 when moving, is taken the depth direction of stove, photographed data is recorded in the data recording equipment 22.Filming apparatus 8 moves the stove depth direction, for example as shown in Figure 3, the thermally insulated container 3 that accommodates filming apparatus 8 is installed on the coking forcing machine 43,, carries out the operation in 43 insertions of coking forcing machine or the extraction stove with certain speed by the action of piston driver 46.Follow shot device 8 when can take continuously, and observe shooting results with the form of animation.
More preferably be that by taking in the depth direction follow shot device 8 of stove, processing can be obtained the image of the wide region of stove depth direction with the form of a width of cloth rest image in conjunction with the photographed data that is recorded in the data recording equipment 22.For example, the translational speed that can make the coking forcing machine is 300mm/ second, and the coverage of cross direction is 100mm, and the shooting interval of rest image is to take in 1/3 second.
In Figure 22, expression engages at image 8 adjacent width of cloth rest images at bonding station 73, form the furnace wall image of the image 72 of wide region.In the image of this wide region, the rest image of every 100mm spacing mirrors the beam reflection light with beam irradiation device 62 irradiations.
As shown in figure 22, if beam reflection Line of light 65 only, the direction of Line of light 65 is parallel with the depth direction of stove, with long single line shape light on the whole, mirrors continuously.If beam reflection is Line of light only, the wire direction of light is parallel with the short transverse of stove, mirrors Line of light towards short transverse with the 100mm spacing.This data processing can be carried out in data recording equipment 22.
When in thermally insulated container, disposing transmission over radio emitter 18, transmitting photographing information from the transmission over radio receiving apparatus 21 of thermally insulated container to the outside, with in this data logging data recording equipment 22 externally, simultaneously, positional information in the stove of filming apparatus (the shooting present position data 35 of horizontal direction in the stove) is recorded in the determinator of the present invention of data recording equipment 22 simultaneously, the depth direction of filming apparatus 8 at stove can be moved and take, select rest image according to positional information in the stove.
Taking rest image with the 100mm spacing on cross direction, this rest image is engaged below, the situation of furnace wall image that is formed in the depth direction wide region of stove describes as an example.For example the rest image of taking is transferred to outside data recording equipment successively with 1/30 second spacing.
In the data recording equipment 22 outside stove, according to positional information in the stove, filming apparatus reaches the rest image of 100mm spacing at every turn and takes the position, selects the rest image that receives this moment.
Thus, the result can be produced on the interior furnace wall image of depth direction wide region of stove by obtaining rest image with the 100mm spacing and engage these rest images on cross direction.If adopt this method, for example change even be equipped with the speed of travel of the coking forcing machine of thermally insulated container, also can be uniformly-spaced to obtain rest image.
Configuration transmission over radio receiving apparatus when being transferred to positional information in the stove the thermally insulated container outside stove, in thermally insulated container, can carry out and above-mentioned same data processing in thermally insulated container.
In addition, can carry out in the thermally insulated container and during the transmission over radio transreceiver of the outer both sides' of stove emission reception in configuration, positional information in the stove is transferred to thermally insulated container outside stove, in thermally insulated container, select rest image, can only the rest image transmission over radio of selecting be transmitted into outside the stove with certain interval.
Filming apparatus 8 when moving, is being taken the depth direction of stove, obtain rest image, engage these rest images, be produced in the observing device of the present invention of furnace wall image of wide region of depth direction of stove, can also take in the mode that produces repeating part at adjacent rest image to each other.
For example, if carry out the shooting of about 100mm spacing on cross direction, the size that makes the cross direction of each rest image is 150mm, produces the repeating part of 50mm.At repeating part, owing to take the identical part in furnace wall, therefore, pass through according to the image of furnace wall, carry out images match and handle, can make two width of cloth images carry out correct position and be combined and make it unification.
If adopt this method, even in the stove of taking each rest image, on the positional information some skews are arranged, also can revise these skews automatically, make the furnace wall image of the depth direction wide region of correct stove.
And then, even under the situation that can not use positional information in the stove,, can enough images match handle the scope of determining the doubling of the image for the image sets that has the repeating part time series to take in the adjacent image, be connected to each other, make correct furnace wall image.
For example, under the situation of observing the pit kiln coking chamber, the furnace wall is because high temperature and the red heat luminous by take this luminous with filming apparatus, can be observed the furnace wall.Like this, as filming apparatus, when using common CCD photographic camera, can make shutter speed is to take about 1/1000 second.
If so fast shutter speed even the translational speed of coking forcing machine is 300mm/ second, also can access the image of the distinctness that does not have photographic camera color inequality.
Light beam image that image analysis is taken and the concrete grammar that carries out quantitative measuring shape are described below.Beam light source uses green laser.Decompose each color composition of colourful CCD video camera, promptly R (red), G (green), each composition of B (indigo plant) read in the recording unit 30.
The image analysis of the measuring shape pair G variation diagram corresponding with optical maser wavelength looks like to carry out.In G variation diagram picture, a little less than the luminous very of furnace wall, beam reflection light can obviously be observed.Therefore, handle, can extract the line segment of beam reflection light out by double quantification.
If it is smooth that the furnace wall brick does not damage fully, this line segment is a straight line, as the (a) and (b) of Figure 14 with (c), if the depression of Δ x is arranged on the furnace wall, produces the distortion of Δ y on the line segment of beam reflection light.Like this, the pixel count of counting deflection Δ y on image.
If photographic camera when taking with respect to the vertical direction of furnace wall, can be obtained Δ x from the relation of Δ x=tan θ * Δ y.The relation of the distance of pixel count on the image and reality can be obtained in advance in addition.
For the depth direction of stove, can be by with running gear follow shot device, the surface, furnace wall of whole length is received on the width of cloth rest image.For the short transverse of stove, also can be according to the distance of minute surface and filming apparatus, still, the scope about common 500~600mm is a coverage.Therefore, to the short transverse of stove, once the scope that can take is limited.
In the pit kiln coking chamber, the part of the damage especially severe of furnace wall refractory for example is limited near positions such as packing into the line of the high direction coal of stove mostly.
Therefore, if make that the present invention locates the position is set for observing near pack into the position line of coal, even for example the range of observation of the high direction of stove is defined, also can obtain enough useful data.
Certainly, by a plurality of furnace wall shape measuring devices are set, once just can observe the furnace wall in the coking forcing machine on short transverse at the wide region of the high direction of stove.
Determinator of the present invention, owing to be shaped as small-sized and light weight, do not need to be provided with cooling tubing etc., therefore, the height that is installed on the forcing machine changes arbitrarily easily, and, measure by the installation site that changes on each given each height, can obtain the furnace wall shape measuring data of the whole height of stove.
In determinator of the present invention,, therefore, possesses supply unit 10 in thermally insulated container inside owing to can't supply with operating power from the outside in measuring.Beam irradiation device 62, filming apparatus 8 or data recording equipment 22, transmission over radio emitter 18 are by the operation power of supplying with from this supply unit 10.As supply unit 10, can use drying battery, charging battery etc.
If use the battery that can't charge as supply unit 10, change battery and all must open thermally insulated container at every turn.In addition, even when using chargeable power supply as supply unit 10, be positioned at thermally insulated container when inner in charging cable connection plug, each charging must be opened thermally insulated container.
Use chargeable power supply as supply unit, further as shown in figure 19, possess charging cable connection plug 25, can not open thermally insulated container and charge, can improve operability by outside at thermally insulated container 3.
Charging cable connection plug 25 is covered its outsides by thermal insulation material lid 34 in inserting stove the time, can only 34 dismountings of thermal insulation material lid be connected charging cables when charging.
The embodiment that shows determinator of the present invention below.
