Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention measures the thickness of carbon deposited on each part of the side wall of the coke oven from the width of the coke oven, and injects air from the injection nozzle based on the measurement data. The present invention relates to a carbon removal method in a coke oven carbonization chamber that controls the amount of carbon removal, and an apparatus for carrying out the method.

[Prior art]

In general, in a coke oven, coal charged in a carbonization chamber is carbonized into coke at high temperatures, and the carbonized coke is discharged from the kiln using an extruder. After that, coal at room temperature is charged again through the coal charging port. The furnace is operated under harsh conditions with large temperature changes, and is used for a long period of over 20 years after construction. Under these circumstances, the partition wall constructed of bricks, etc. that separates the carbonization chamber from the combustion chamber of a coke oven, especially on the side wall of the carbonization chamber, is exposed to the decomposition of hydrocarbons generated during the carbonization process of coal. Carbon adheres and grows to form a thick layer.

If this is left untreated, coke will become clogged, causing damage such as cracks and chips to the bulkhead bricks. Also, the thermal conductivity from the combustion chamber will decrease, so operations will have to be stopped and the adhesion caused. The carbon must be burned off by the oxidation effect of the air, which throws off the operational plan. Therefore, it is best to make a plan to periodically burn off the carbon from the wall, but since the amount and condition of carbon adhering to and growing on the wall are not constant, it is difficult to determine the frequency of burning off in advance. .

In order to solve these problems, an apparatus has been proposed that measures the width of the carbonization chamber, which changes depending on the amount of carbon deposited, at high temperatures and estimates the state of the wall surface. For example, JP-A-57-536
As disclosed in No. 12, after extruding the carbonized coke from the carbonization chamber, a measuring device is installed on the pusher beam of the coke extruder or near the ram at the tip,
A thin rod-shaped guide is taken out from within the device using a biasing means such as a spring, and a roller attached to the tip of the guide is brought into contact with the wall surface.
A device that measures the distance from the pusher to the wall using a mechanism provided at the end of the guide is common.

In addition, we focused on the fact that there is a certain relationship between the total amount of adhered carbon and the extrusion current value of the extruder, and when the extrusion current value exceeds a predetermined reference value, A method has been disclosed in which a part of the tube is opened to the outside air and a nozzle is inserted using a loading vehicle to inject air or the like to burn off the adhering carbon (Japanese Patent Laid-Open No. 61-231086).

Incidentally, the growth rate of carbon adhering to the wall surface is greatly influenced by the temperature of the wall surface, and in a carbonization chamber where the wall surface temperature is not uniform, the thickness of the carbon adhering to the wall surface is not uniform. In addition, the adhered carbon has the function of sealing the wall brick joints to prevent generated gas from leaking into the combustion chamber, and in order to fulfill this sealing function, it is applied uniformly over the entire surface and to a thickness of about 1 cm to prevent clogging. The ideal state is that ~3n of carbon is attached to the wall surface.

However, as disclosed in JP-A No. 61-231086, if carbon burn-off is performed uniformly based on the total amount of attached carbon, not only will there be variations in the amount of carbon remaining after burn-off, but also the burn-off Excessive carbonation causes the bare surface of the wall to become exposed, and the sealing function of the joints is not fulfilled, leading to the generation of black smoke due to gas leaking from the carbonization chamber to the combustion chamber.

Therefore, JP-A No. 61-231084 focuses on the fact that the thickness of the carbon deposited in the carbonization chamber is not uniform, measures the distribution of the amount of deposited carbon, and adjusts the amount of air jetted from the nozzle based on the measured value. is disclosed. However, regarding the equipment and method for measuring the thickness of deposited carbon,
Applicable general device names and measurement methods are only exemplified, without specific disclosure.

Furthermore, in the disclosed example, the air injection nozzle is inserted into the carbonization chamber by a charging car provided separately from the coke extruder, so the air injection nozzle and a mechanism for insertion are added to the charging car. This requires a large-scale device. Moreover, in a carbonization chamber that is generally configured with 3 to 5 coal charging ports in the longitudinal direction, the distance between the coal charging ports is 2 m or more, and carbon burning between the coal charging ports is sufficient. The problem was that it could not be carried out.

In addition, as a device for measuring the width of the carbonization chamber to detect the amount of carbon deposited, a contact type measuring device using a guide such as that disclosed in JP-A No. 57-53612 does not allow for defects such as chips or joint cuts in the bricks on the wall of the carbonization chamber. If there is a defect, the tip of the guide will get caught in these recesses, or the guide will be deformed by the impact of the catch, making measurement impossible. Further, if the contact at the tip of the guide is a roller, it cannot enter into a recess or the like having a width smaller than the roller diameter, which results in a correspondingly lower measurement accuracy.

Furthermore, the partition walls of the carbonization chambers may tilt as a whole due to long-term operation, and the widths of the carbonization chambers may differ between the respective carbonization chambers. Therefore, the amount of carbon deposited cannot be immediately determined by precisely measuring the width of the carbonization chamber.

[Problem that the invention seeks to solve]

The present invention has been made to solve these problems, and provides a method and a method for effectively burning off carbon adhering to the wall surface of the carbonization chamber of a coke oven without interfering with coke carbonization work and using a small amount of equipment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on drawings showing embodiments thereof. FIG. 1 is a front sectional view of a coke oven according to the present invention. In the figure, reference numeral 1 denotes a carbonization chamber, which has a width of 35 to 55 cIn, a height of 4 to 7 m, and a length of 10 to 17 m. A large number of combustion chambers 3 are provided alternately. A plurality of coal loading ports 11, 11. ... is installed, and the coal input from each coal charging port is indirectly heated from the combustion chamber 3, and carbonization is performed while the temperature rises to about 1000 degrees Celsius, which takes more than 10 hours. .

Next, as shown in the side sectional view of the carbonization chamber 1 shown in FIG. 2, the coke 4 remaining after carbonization is removed from the machine side on the right side of FIG. Carbonization chamber width measuring devices 5a and 5b are placed at two locations corresponding to the heights of the carbonization chamber widths, and compressed air is placed on the bushing beam 61 at a height corresponding to the height measured by the measuring devices 5a and 5b. The second
The ram head 62 is pushed out at a predetermined speed to the coke side on the left side of the figure, and the position of the ram head 62 is detected by the ram head position detector 12 attached to the extruder 6, and the measuring device 5a
, 5b indicates the width of the carbonization chamber 1, that is, the partition walls 2 on both sides of the carbonization chamber.
The distance between ゜2 and the wall surface condition are detected at predetermined intervals,
This detected value is associated with the position of the ram head 62 detected as described above, and is stored in a storage device installed in the extruder 6 together with a number specifying the carbonization chamber. Furthermore, the extruded coke is put into a fire extinguishing truck 8 via a guide car 7 that freely travels along the coke side, and then extinguished. Furthermore, although not shown, a heat storage chamber is provided at the bottom of the carbonization chamber 1 for preheating the fuel gas and air and for recovering heat from the exhaust gas after combustion.

FIG. 3 is a Pronk diagram showing the configuration of the carbon removal device, and the width of the carbonization chamber measured by measuring devices 5a and 5b is as follows:
The data is input to the position analysis device 13 together with data on the ram head position detected by the ram head position detector 12 . The position analysis device 13 stores the carbonization chamber width measurement value immediately after carbon is almost completely removed by long-term carbon burning as a reference value for the carbonization chamber width, and the input measurement value and reference value are stored in the position analysis device 13. The deposited carbon thickness can be calculated from the difference. For carbonization chambers for which there is no measurement of the width of the carbonization chamber when carbon has been almost completely removed, the amount of carbon deposited is estimated from the temporal change in the distribution of the width of the carbonization chamber, which is obtained by measuring each time coke is extruded. .

The data on the carbon adhesion amount distribution thus obtained is stored in the storage device 14 in association with a number identifying the carbonization chamber. The nozzle injection amount controller 15 reads these analytical data and controls the air amount and air pressure for the nozzles 10a and 10b.

Next, to explain the nozzles 10a and 10b in detail, FIG. 4 is a partially cutaway perspective view of one nozzle 10, which has nine injection ports 101, 101, . . . in the vertical direction. , these injection ports 101, 101... are provided with two-stage bath shocks 102, 103 in order to evenly distribute the compressed air sent to the injection ports 101, 101..., making the injection amount uniform. We are trying to This single nozzle 10 can spray air over a range of about 300 m in the height direction.

Note that the shape of the nozzle and the number of injection ports are not limited to these as long as they can uniformly inject air onto the wall surface.

Furthermore, the position where the nozzles 10a and 10b are installed is not limited to the top of the pusher beam 61, but may be on the back surface of the ram head 62.

The measuring devices 5a and 5b are both constructed with a double box structure inside and outside the outer wall 51, as shown in the front cross-sectional view of FIG. 5 and the side cross-sectional view of FIG. Room 1
Cooling water is supplied from the outside of the measuring device 5a from a water supply pipe (not shown) installed along the pusher beam 61.
, 5b, while this cooling water is discharged to a drain pipe (not shown) arranged along the pusher beam 61. The two opposing surfaces of the outer wall 51 are made of quartz glass having a height and size that allows the light emitted from the light source 54a to be reflected by a mirror 55, which will be described later, and the reflected light reflected by the carbonized interior wall to pass through. Windows 52 and 52 are respectively provided, and these windows 52 and 52 are each held on the wall by a window material fixing jig. Moreover, these windows 52.
52 has the above-mentioned height and size, and preferably has a size that can minimize the intrusion of radiant heat from the outside. Furthermore, nitrogen gas is sent from the outside of the carbonization chamber 1 to the inside of the box through an air supply pipe (not shown) installed along the pusher beam 61 to cool the inside of the box.
It is discharged to the outside through the gap around the window 52.52.

Further, the measuring equipment housed inside is fixed to a fixed frame 53 whose front and side surfaces have a U-shaped cross section.
The spring 57. is attached to an appropriate position on the inner surface of the outer wall 51 along with the equipment.
57..., the resonant frequency is suppressed as low as possible, and damage to internal equipment due to vibration of the measuring devices 5a, 5b is prevented. A light source 54a is provided in the upper half of the fixed frame 53.
A set of optical rangefinders 54 is provided, which includes a light source 54a that emits laser light downward, and a detector 54b that
It is arranged with an inclination of a predetermined angle to allow the reflected light from the measurement object to enter. Further, at the bottom of the fixed frame 53, a mirror 55, which is a reflecting surface, is rectangular in plan view and rear view, and has a right isosceles triangle in cross section, is disposed with the right angle as the apex. It has a size that allows it to reflect the emitted light from the window 52 to the outside and to allow the light reflected from the measurement object within a required range to enter. Further, the mirror 55 is mounted on a movable base 5 which is slidable in the vertical direction of the window 52, 52 by the protrusion and retraction of a cylinder (not shown).
It is placed on 6. Furthermore, in this embodiment, the light source 54a
A laser beam with a wavelength of 850 nm is used as the mirror 55, and a special mirror that can reflect light of this wavelength with high reflectance is used as the mirror 55. Further, in the fixed frame 53 in the vertical direction, a transparent window 57 having the same size or more as the window 52 is provided in a portion interposed between the window 52 and the mirror 55, and allows reflected light to pass through.

Next, the principle of distance measurement using the measuring devices 5a and 5b having such a configuration will be explained with reference to the optical path diagrams shown in FIGS. 6 and 9. Distance l from the light source 54a to the reflection point R1 on the reflection surface of the mirror 55. , the distances from this reflection point R1 to both wall surfaces to be measured are 1. ．． 12, then 7! from the angle of incidence of the reflected light from the re-measured object onto the detector 54b, which is determined by sliding the mirror 55 in the vertical direction of the measured object at the same measurement position. o+11 and p.

By finding the value of +p2 by trigonometry and subtracting a constant value lo from these values to calculate i, +7!2, the distance between the two opposing measurement objects can be found.

A method for measuring the width of the carbonization chamber based on the configuration and principle as described above will be explained. The measuring devices 5a and 5b are as shown in FIG.
The windows 52 and 52 are installed facing both corner walls 2.2 at heights where carbon tends to adhere as determined by experience, and water and nitrogen gas for cooling are supplied through each pipe to a measuring device 5a,
5b. The extruder 6 causes the pusher beam 61 to enter the carbonization chamber 1 at a speed of 20 m/m'in, and the ram head 62 at the tip pushes out the carbonized coke, while the measuring devices 5a and 5b measure the mirror every 0.2 seconds. 55, and the distances p1 and p2 to the partition walls on both sides are alternately detected by trigonometry using laser light. Therefore, although the detection points 11 and 7!2 are not strictly opposite positions, if the movement is at a low speed of 20 m/min, the detection points 11 and 7! There is no concern that the pusher beam 61 moves left and right significantly while moving forward, causing the fixed center line 411 to shift, and the sum of the distances to both corner walls 2.2 not being able to indicate the width of the coking chamber.

Measuring device 5a using the optical distance meter as described above.

5b, high-precision distance measurement is performed with a measurement accuracy of 0.1 to Q, 5 mm, and the wall condition of the carbonization chamber 1 can be quantitatively captured, making it easy to estimate the situation.

Furthermore, since optical measurement devices perform measurements using reflected light, if there is a limit to the size of the measurement device, the range of reflected light that can enter a fixed detector is also limited, and the detector The measurable range is determined according to the detectable range. Therefore, if the measurement accuracy of the laser beam is high, if the wall brick is exposed after burning off the adhering carbon on the wall, etc.
Laser light irradiation can be performed to measure minute points of change such as joint cuts and cracks in bricks, but if the depth exceeds the measurement capability of the device, abnormal values may be obtained. In addition, the device will show an abnormal value if the depth exceeds its measurement ability, not only for minute depressions but also for pits caused by missing bricks, etc. Different methods may be used to deal with these abnormal values, such as plasma spraying for joint breaks, cracks, etc., and replenishment of missing bricks. Therefore, when an abnormal value occurs, if it is possible to understand the specific situation near the measurement point, it is possible to not only measure the width of the coking chamber but also to
Appropriate measures to preserve the carbonization chamber 1 can be taken immediately. Therefore, the concrete situation of the wall surface is imaged using a small TV camera or the like. Since the wall surface to be imaged has a temperature of 800 to 1000° C., a good image can be obtained without using a particular light source. Since the size of the measuring devices 5a and 5b is limited by the width dimension of the carbonization chamber 1, a structure is used that images the wall surface reflected on the mirror 55 for distance measurement. That is, as shown in FIG. 9, the distance between the light source 54a and the detector 54b is 200 m.

Distance Mlt from the light source 54b to the light reflection point R1 on the mirror 55 7! In the optical distance meter 54 of this embodiment in which o is 1251, the distance from the reflection point R2 to the wall surface to be measured is 1ilI I12 = 230 inches.
For a change of 50 mm in tJJlt, the amount of horizontal change in the mirror 55 at the reflection point R2 is a small value of 10.2fl, and the reflection point R1 is a fixed point, and the reflection surface used for distance measurement is a narrow range. be. Therefore, Figure 5,
As shown in FIG. 6, a regular mirror for JjJE is installed in IL'Lflt 55b in mirrors 55a and 55a for distance measurement using special mirrors, including reflection points R, , R2 on both sides of the mirror 55, respectively. is used to arrange these on the same plane, while placing an imaging device 59 such as a small TV camera or the like in opposition to the intermediate portion 55b, and photographing the wall surface projected onto the mirror intermediate portion 55b at the same time as measuring the width; Observe this image from the outside. Further, the situation may be examined after the measurement is completed, such as by recording on a VTR.

Furthermore, distance! Fi! When associating the laser beam irradiation point for regular use with the corresponding position on the image, the laser beam and its optical axis must be aligned because the laser beam in this example has a wavelength of 850 nm and it is not possible to tell visually which position it is hitting. let me,
Alternatively, by projecting visible wavelength laser light or white light in parallel, it is also possible to clearly locate the laser light irradiation point for distance measurement in the image.

By performing the measurements as described above, the condition of the wall surface of the carbonization chamber is determined from the width of the carbonization chamber and/or from the image, and based on this, the wall surface is repaired by burning off the wall carbon and using plasma spraying.

In this example, the distance to both walls is alternately measured using one set of rangefinders, but as shown in Figs.
As shown in the figure, the above-mentioned optical distance meter 54 is
A configuration may also be adopted in which a stand is mounted and each wall surface is measured simultaneously. In that case, the mirrors are fixed mirrors 55C, 55C each having a predetermined angle with respect to each wall surface.

Further, as shown in FIGS. 7 and 8, the light source 54a and the detector 54b constituting the distance meter 54 are slid in the vertical direction.
If the variable mechanism 60 is provided, the distance range that can be measured by the distance meter 54 will be expanded. This variable mechanism 60
It is also possible to apply this embodiment to the case in which one set of 4 is mounted.

Furthermore, in this example, the distance was measured by trigonometry using a laser beam, but a method in which the laser beam is intensity-modulated and emitted and the distance is measured based on its flight time, or other optical distance measurement methods may be used. It is also possible.

Further, in this embodiment, the imaging mirror is provided as a part of the distance measuring mirror, but it may be provided separately as long as it is on the same plane near the distance measuring mirror.

Furthermore, in this embodiment, the mirror that reflects the light from the light source is configured to be slidable, but as shown in FIG. Similar effects can be obtained by using a configuration in which the rotating double-sided mirror 55d is used to change the direction of reflected light.

Next, the carbon removal method according to the present invention will be explained.

That is, although coke extrusion is performed every 20 to 24 hours, the width of the coking chamber is measured during the period when the extruder 6 pushes out the coke, or during the period when the ram is pulled back to the initial position after extrusion is completed, and the measured data is Based on this, the analysis of the distribution of the amount of adhering carbon in the horizontal direction of the carbonization chamber and the drawing of the shape based on the analysis are as follows.
This is carried out while the extruder 6 is moving to the next carbonization chamber. After completing coke extrusion and carbonization chamber width measurement for all carbonization chambers, when performing the next coke extrusion, the amount of adhered carbon on the wall surface of each carbonization chamber is greater than a predetermined amount based on the analytical data. Quantity according to quantity.

Pressurized air is injected from nozzles 10a and 10b to burn off the carbon. Therefore, during coke extrusion that is repeated periodically, measurement and removal are performed alternately, and there is a time difference of 20 to 24 hours between measurement and removal.
Empirically, the amount of carbon deposited in 4 hours is 0. It is known that the time delay is about in, so there is no need to consider the influence of time delay.

In this example, data analysis after measuring the coking chamber width was performed during movement to the next coking chamber, but the measurement and analysis was performed during the coke extrusion period, and after the end of extrusion, the data analysis was performed during the period when the ram was pulled back. Alternatively, air may be injected based on analytical data to burn off the carbon.

In addition, in this example, measuring devices and nozzles were installed at two heights where carbon is likely to adhere, but the number of installed nozzles was increased, rather than being attached to two positions, to achieve a more uniform amount of carbon adhesion. It is possible to realize the distribution.

〔effect〕

The method of the present invention makes it possible to remove carbon according to the amount of attached carbon, thereby preventing clogging, and preventing the occurrence of steps and deformation of the furnace wall caused by pressure applied to the furnace wall due to clogging. In addition to extending the lifespan, it maintains a uniform amount of carbon adhesion on the wall surface, seals the joints of partition wall bricks,
It has an excellent effect of preventing the generation of black smoke due to gas leakage from the carbonization chamber to the combustion chamber.

Furthermore, by installing the device of the present invention in a coke extruder, carbon can be removed evenly from the longitudinal direction of the wall surface of the coking chamber, and no special equipment is required to insert the removal device, increasing production efficiency. It has an excellent effect of increasing
