Description

Raw material processing method and raw material processing apparatus {PROCESSING METHOD AND PROCESSING APPARATUS FOR RAW MATERIAL}

The present invention relates to a raw material processing method and raw material processing apparatus, and more particularly, to a raw material processing method and raw material processing apparatus capable of detecting the height and temperature of coke without exposing workers to danger.

A coke oven for producing coke by carbonizing coal includes a carbonization chamber and a combustion chamber. Coal, that is, raw coal, which is a raw material for coke, is charged into the carbonization chamber, and fuel gas for heating the carbonization chamber is supplied and combusted in the combustion chamber. In addition, each of the carbonization chamber and the combustion chamber is provided in plurality, and the carbonization chamber and the combustion chamber are alternately arranged.

The raw coal in the carbonization chamber is heated by a heat source supplied from the combustion chamber to become coke. At this time, it is necessary to sufficiently carbonize the raw coal for the quality of the coke, and the temperature of the coke after completion of the carbonization may be different depending on the carbonization state. At this time, the temperature of the coke may vary according to the charging amount of the raw coal charged to the carbonization chamber, that is, the charging height, as well as the supply amount of the fuel gas supplied to the combustion chamber. That is, when raw coal is loaded into the carbonization chamber at a height higher than a certain amount, a problem may occur in that the upper part of the loaded raw coal is not sufficiently carbonized. In addition, when raw coal is charged at a height less than a certain amount into the carbonization chamber, since there is no raw coal to be carbonized at the top of the carbonization chamber, the amount of raw coal relative to the amount of heat supplied to the carbonization chamber is small, resulting in inefficient energy consumption.

Accordingly, after dry distillation is completed, the height of coke is measured. At this time, a worker inserts a measuring instrument into the carbonization chamber from the upper side of the carbonization chamber to measure it. At this time, a worker may be exposed to high-temperature heat, which may cause a safety problem.

Here, (a) of FIG. 3 is a state before the raw coal (hereinafter referred to as coke) after completion of dry distillation is extruded out of the carbonization chamber, and (b) of FIG. 3 is a view showing after the coke is extruded.

The carbonization chamber 1110 has a cylindrical shape with an internal space, and extends in a second direction (Y-axis direction) crossing the first direction (X-axis direction) in which the carbonization chamber 1110 and the combustion chamber 1120 are arranged side by side. do. In addition, doors are installed at both ends of the carbonization chamber 1110 in the second direction (Y-axis direction).

The combustion chamber 1120 generates a flame by burning fuel gas provided from the fuel supply unit 1130 . The combustion chamber 1120 extends in the direction in which the carbonization chamber 1110 extends, that is, in the second direction (Y-axis direction).

The carbonization chamber 1110 and the combustion chamber 1120 may have different heights. That is, as shown in (a) of FIG. 3, the height H ₁ of the carbonization chamber 1110 may be higher than the height H ₂ of the combustion chamber. At this time, the carbonization chamber 1110 may have a bottom surface equal to the height of the combustion chamber 1120, and an upper surface height higher than that of the combustion chamber 1120.

In charging the raw coal into the carbonization chamber 1110, it is preferable to charge the raw coal so that the height of the raw coal in the carbonization chamber 1110 is equal to the height of the combustion chamber 1120. Accordingly, in setting the height at which raw coal is charged into the carbonization chamber 1110, the reference height H _s may be set using the height H ₂ of the combustion chamber 1120. Here, the reference height H _s may be a range value. This reference height H _s will be described again when the controller 2000 is described later.

As shown in (a) and (b) of FIG. 3 , each of the carbonization chamber 1110 and the combustion chamber 1120 may be surrounded by a wall 1140 made of a refractory material. In addition, a shell 1150 may be installed outside the refractory wall 1140 .

A fuel supply unit 1130 is connected to the combustion chamber 1120 to provide fuel gas to the combustion chamber 1120 . The fuel supply unit 1130 includes a pipe 1131 connected to each of the plurality of combustion chambers 1120, a valve 1132 installed in the pipe 1131 to communicate with the combustion chamber 1120 and adjust the fuel gas supply amount, and the pipe 1131 It may include a gas storage unit 1133 supplying fuel gas to the.

Also, the second gas may be, for example, air. At this time, the pipe 1131 may include a first pipe for supplying the first gas to each combustion chamber 1120 and a second pipe for supplying the second gas, and the valve 1132 is provided in each of the first and second pipes. ) can be installed.

The extrusion unit 1300 is an extruder 1310 capable of moving forward and backward in the extension direction of the carbonization chamber 1110, that is, in the second direction (Y-axis direction) and the extruder 1310 to provide a driving force for moving the extruder 1310 forward and backward. It includes an extrusion driver 1320 connected with.

In addition, the extruder 1300 is located below the extruder 1310 and the extrusion driver 1320 and is movable in a direction in which a plurality of carbonization chambers 1110 are arranged, that is, a body 1340 that is movable in a first direction (X-axis direction) , It may include a support 1330 installed on top of the body 1340 to support the extruder 1310 and the extrusion driver 1320.

And the extrusion part 1300 is mounted on the body 1340 to support the lower part of the body 1340, and a wheel that can slide along the rail (R) installed on the ground or the floor of the workshop It may include a moving unit 1350 provided. At this time, the rail R is installed to extend in a first direction (X-axis direction) in which a plurality of carbonization chambers 1110 are arranged. Thus, by the operation of the wheel of the moving unit 1350 sliding on the rail R, the entire extrusion unit 1300 may move horizontally in the direction in which the plurality of carbonization chambers 1110 are arranged.

The extruder 1310 extends in the second direction (Y-axis direction), which is the extension direction of the head 1311 and the carbonization chamber 1110, which pushes and extrudes the coke C of the carbonization chamber 1110, so that the head 1311 It includes a beam 1312 connected to the rear end.

The head 1311 may be provided in a plate shape corresponding to the carbonization chamber 1110. For example, when the carbonization chamber 1110 has a rectangular cross section, the head 1311 is preferably provided in a rectangular plate shape.

The beam 1312 may be connected to the extrusion driver 1320 and move forward toward the carbonization chamber 1110 and backward in the opposite direction to the carbonization chamber 1110 by the operation of the extrusion driver 1320. Accordingly, the head connected to the beam 1312 may move forward and backward with respect to the carbonization chamber 1110.

Hereinafter, the temperatures of the carbonization chamber 1110, the coke (C), the refractory wall 1140, and the steel shell 1150 will be described with reference to FIG. 3(a).

As described above, coke (C) is produced by carbonizing the raw coal charged into the carbonization chamber 1110. At this time, the temperature of the coke (C) and the temperature of the carbonization chamber 1110 may vary depending on the supply amount of the fuel gas supplied to the combustion chamber 1120. In addition, the temperature of the iron shell 1150 is lower than that of the carbonization chamber 1110 or the coke (C) because it is exposed to the outside air or the outside. In addition, since the refractory wall 1140 is located between the shell 1150 and the carbonization chamber 1110, the temperature of the refractory wall 1140 is higher than that of the shell 1150, and the temperature of the carbonization chamber 1110 and the coke (C) lower than the temperature.

Hereinafter, the respective temperatures of the coke (C), the carbonization chamber 1110, the refractory wall 1140, and the shell 1150 will be described as examples.

For example, when carbonization is completed in the carbonization chamber 1110, the temperature of the coke (C) in the carbonization chamber 1110 may be, for example, 400 °C to 600 °C. In addition, when the raw coal is charged into the carbonization chamber 1110, since the height of the raw coal is lower than the height of the carbonization chamber 1110, an empty space exists above the loaded coke C. That is, there is an empty space on the upper side of the upper surface of the coke (C) loaded in the carbonization chamber 1110, and the temperature of this space is more than 600 ° C and less than 1000 ° C. More specifically, it may be 700 ° C to 1000 ° C. .

The temperature of the refractory wall 1140 surrounding the carbonization chamber 1110 may be lower than that of the coke (C) and the carbonization chamber 1110. That is, when the temperature of the coke (C) is 400 ° C to 600 ° C, the temperature of the refractory wall 1140 may be 300 ° C or more and less than 400 ° C. At this time, the temperature of the refractory wall 1140 is higher as it is closer to the carbonization chamber 1110 in the thickness direction, and lower as it is closer to the shell 1150. That is, the temperature of the refractory wall 1140 may decrease from the interface with the carbonization chamber 1110 to the interface with the shell 1150.

In addition, the refractory wall 1140 is surrounded by the enclosure 1150, and since the enclosure 1150 is exposed to the outside air, the enclosure temperature 1150 is lower than that of the refractory wall 1140. That is, the temperature of the steel shell 1150 may be less than 300° C., and the temperature may decrease toward the outside from the interface with the refractory wall 1140.

In this way, the temperatures around the carbonization chamber 1110 of the coke oven 1100, the coke C charged in the carbonization chamber 1110, and the carbonization chamber 1110 are different. Therefore, a controller 2000 having an imaging unit 2110 capable of taking an image of the carbonization chamber 1110 and its surroundings and generating a picture image to appear in different colors according to the temperature (or heat) of the imaging position is provided did

Returning to FIGS. 1 and 2 again, the controller 2000 will be described.

1 and 2, the controller 2000 detects the temperature of the coke (C) and the area ratio of the coke (C) using an image image obtained by imaging the carbonization chamber 1110. A detection unit (2100) , a control unit 2200 for controlling the operation of at least one of the charging unit 1200 and the fuel supply unit 1130 using the temperature and area ratio of the coke C detected by the detection unit 2100.

In addition, the controller 2000 may further include a display unit 2300 that displays the temperature of the coke and the area ratio of the coke detected by the detection unit 2100 so that an operator can check them.

The detection unit 2100 captures an image of the carbonization chamber 1110 to obtain an image including temperature data for each position of the carbonization chamber 1110, and the coke in the carbonization chamber 1110 using the image (C) may include a processing unit 2120 that detects or predicts the temperature and calculates the area ratio of the area occupied by the coke (C) on the image image. In addition, the detection unit 2100 is a determination unit 2130 that determines whether the coke C is normally carbonized and whether the coke C is normally charged using the temperature and area ratio of the coke C detected by the processing unit 2120 can include

The imaging unit 2110 may be installed to be positioned in front of the coke oven 1100 as shown in FIGS. 1 and 2 . For example, the imaging unit 2110 may be mounted on a support 1330 supporting the extruder 1310 . More specifically, as shown in FIG. 2, among one end and the other end of the body 1340 in the second direction (Y-axis direction), it is fixed to the support 1330 so as to be positioned relatively adjacent to one end facing the coke oven 1100. can be installed In addition, the imaging unit 2110 does not interfere with the extruder 1310 moving in the direction in which the extruder 1310 moves toward the carbonization chamber 1110, that is, in the second direction (Y-axis direction) of the extruder 1310 as shown in FIG. It may be installed to be located on one side of the first direction (X-axis direction).

In imaging the carbonization chamber 1110 using the imaging unit 2110, in one carbonization chamber 1110, the coke (C) is extruded out of the carbonization chamber 1110 using the extruder 1310. , After the coke (C) is extruded out of the carbonization chamber 1110, it is imaged. That is, images are taken before and after coke (C) extrusion, respectively. In imaging the carbonization chamber 1110 before and after extrusion of the coke C, it is preferable to move the extruder 1310 backward so that the head 1311 is positioned behind the imaging unit 2110. This is to prevent the head 1310 of the extruder 1310 from covering at least a portion of the field of view of the imaging unit 2110 when the head 1311 is located in front of the imaging unit 2110.

Then, the extrusion unit 1300 sequentially extrudes the coke C of each of the plurality of carbonization chambers 1110 while moving in the first direction (X-axis direction). At this time, the imaging unit 2110 installed in the extrusion unit 1300 moves in the first direction together with the extrusion unit 1300, and captures images before and after extrusion for each of the plurality of carbonization chambers 1110.

The installation position of the imaging unit 2110 is not limited to the above-described example, and as long as the carbonization chamber 1110 can be imaged while moving in the direction in which the plurality of carbonization chambers 1110 are arranged, it may be installed in any location and any device. .

As described above, in one carbonization chamber 1110, images are taken before and after extrusion of coke (C), which is to calculate the area ratio of coke to the entire carbonization chamber 1110 in the processing unit described later. At this time, the image image captured before extrusion of coke (C) can be used to calculate the area of coke in the carbonization chamber 1110, and the image image captured after extrusion of coke (C) represents the area for the entire carbonization chamber 1110 can be used to calculate

4 is an example of a picture image acquired by an imaging unit of a controller according to an embodiment of the present invention. Here, (a) to (c) of FIG. 4 are image images of a state before extruding the carbonized coke out of the carbonization chamber, and FIG. 4 (d) is an image image after extruding the coke out of the carbonization chamber.

A video image is composed of a plurality of pixels, and each of the plurality of pixels may have the same size. Also, the imaging unit 2110 may be a means for preparing an image by implementing different colors according to the temperature of an imaging location corresponding to each of a plurality of pixels. The imaging unit 2110 may be a means including a thermal imaging camera.

For example, the imaging unit 2110 represents temperatures of 400°C to 600°C as orange, purple, and red colors. In addition, the imaging unit 2110 may generate an image such that the higher the temperature in the temperature range of 400 °C to 600 °C, the orange series, purple series, and red series are changed in order. In addition, the imaging unit 2110 may generate an image by displaying a temperature of more than 600°C and less than 1000°C in yellow color. In addition, the imaging unit 2110 may generate an image by displaying a temperature of 300° C. or more and less than 400° C. in a purple-based color, and displaying a temperature of less than 300° C. in indigo-based or black-based colors.

The processing unit 2120 identifies the color on the image image, so that the region where coke exists (coke region S _c ) on the image image, the carbonization chamber region (S _e ) that is an empty space, and the refractory wall 1140 and carbonization A boundary area (S _b ) and a sheath area (S _m ) between yarns 1110 may be identified or distinguished.

Hereinafter, referring to (a) to (d) of FIG. 4 , a coke area (S _c ), a carbonization chamber area (S _e ), a boundary area (S _b ), and a shell area (S _m ) describes how to identify or distinguish them.

Referring to (a) of FIG. 4 , there is a continuous area from the lower side to the upper side on the image image, and there is an area represented by at least one of orange, purple, and red colors. And the temperature of the coke at which dry distillation is completed is 400 ° C to 600 ° C, and the temperature of 400 ° C to 600 ° C is represented by orange-based, purple-based and red-based colors. Accordingly, the processing unit 2120 identifies the areas displayed in orange, purple, and red colors as coke or coke-loaded coke areas S _c on the image.

Also, in (b) and (c) of FIG. 4 , there are areas that are continuous from the lower side to the upper side of the image image and are indicated by orange, purple, and red colors. Accordingly, the processing unit 2120 identifies this area as a coke area S _c .

At this time, comparing (a) to (c) of FIG. 4 , the upper height of the coke area S _c is different, which may vary depending on the loading amount of raw coal. That is, as the amount of raw coal charged into the carbonization chamber 1110 increases, the upper height of the coke region S _c identified on the image image increases.

Referring to (d) of FIG. 4 , there is a continuous yellow area from the lower side to the upper side of the image. The temperature of the yellow series is above 600 ° C and below 1000 ° C, and this temperature is the temperature of the carbonization chamber in a state where no coke is loaded. Accordingly, the processing unit identifies the area shown in yellow on the image as an empty space area not filled with coke, that is, a carbonization chamber area (S _e ).

And, even in a state where coke (C) is loaded in the carbonization chamber 1110 (before extrusion), an empty space exists above the coke (C) as shown in FIG. 3 (a). Accordingly, the carbonization chamber region (S _e ), that is, the empty space region (S _e ), indicated in yellow as described in ( _d ) of FIG. It can also appear on visual images. That is, referring to (a) to (c) of FIG. 4 , there is an area above the coke area S _c on the picture image, and an area indicated by a yellow color system exists. This region is imaged in a yellow-based color because the temperature of the empty space region where the coke is not loaded exceeds 600 °C and is less than 1000 °C when the temperature of the coke is 400 °C to 600 °C. Therefore, the processing unit 2120 is an upper region of the coke region S _c on the image image, and the region represented by a yellow-based color is an empty space region S _e that is not filled with coke in the carbonization chamber, that is, the carbonization chamber area ( S _e ) can be identified.

Referring to (d) of FIG. 4 , a purple-based region exists along the outer circumference of the yellow-based region. This is a region having a temperature of 300 ° C. or more and less than 400 ° C., and is a boundary region S _b between the refractory wall 1140 and the carbonization chamber 1110 . In addition, since the refractory wall 1140 is formed along the circumference of the carbonization chamber 1110, the shape of the boundary region S _b may correspond to the shape of the carbonization chamber 1110. Therefore, the processing unit 2120 converts the area shown in a purple color to a shape corresponding to the carbonization chamber 1110 or extending in the circumferential direction on the image image to the boundary area between the refractory wall 1140 and the carbonization chamber 1110 (S _b ).

In addition, since the carbonization chamber 1110 is surrounded by the refractory wall 1140, when the boundary region S _b is identified on the image, the inner region of the boundary region _AB is defined as the carbonization chamber region S _e . can be identified by That is, in identifying the carbonization chamber area (S _e ), the processing unit 2120 identifies the area indicated by the yellow area as the carbonization chamber area (S _e ), or identifies the inner area of the boundary area (S _b ) as the carbonization chamber area ( S _e ) can be identified.

This boundary region S _b may also appear in (a) to (c) of FIG. 4 where a coke region S _c exists. That is, referring to (a) to (c) of FIG. 4 , a purple-colored area exists along the outer circumference of the coke area S _c and the empty space area S _e on the image. Therefore, the processing unit 2120 has a purple color to extend in the circumferential direction or in a shape corresponding to the carbonization chamber 1110 even on the image with the coke area S _c as shown in (a) to (c) of FIG. It can be identified that the colored region is the boundary region S _b between the refractory wall 1140 and the carbonization chamber 1110 .

Referring to (a) to (d) of FIG. 4 , a blue-based or black-based region exists outside the boundary region. This is a region having a temperature of less than 300 °C and corresponds to the shell region (S _m ). Accordingly, the processing unit 2120 identifies an area appearing in indigo or black on the image as the fur area S _m .

The processing unit 2120 identifies the coke area (S _c ), the carbonization chamber area (S _e ), the boundary area (S _e ), and the shell area (S _m ) on the image in the same manner as described above. Then, the processing unit 2120 predicts or detects the temperature (T _p ) of the coke at which dry distillation is completed, using each color of a plurality of pixels in the identified coke region (S _c ). More specifically, each of a plurality of pixels forming the coke area S _c on the image image has a color according to temperature. Accordingly, the temperature of each of the plurality of pixels can be known, and the average of the temperatures of each of the plurality of pixels is calculated. And the calculated average temperature is predicted or detected as the temperature of coke (T _p ). The detected coke temperature (T _p ) is then used in the determination unit 2130 to determine whether or not the coke has been carbonized sufficiently.

In addition, the processing unit 2120 captures the image image before extrusion (first image image), for example, the area (A) of the coke region S c on the image image, such as any one of (a) to ( _c ) of FIG. _c ). Then, the processing unit 2120 calculates the area A _e of the carbonization chamber region S _e on the image image (second image image) captured after being extruded, for example, as shown in (d) of FIG. 4 . More specifically, the area (A _{c ) of the coke area (S c )} can be calculated using the number of pixels and the area of one pixel in the coke area (S _c ) on the captured image before extrusion. In addition, the area (A _c ) of the carbonization chamber region (S _e ) is calculated using the number of pixels and the area of one pixel in the carbonization chamber region (S _e ) on the captured image after extrusion.

In addition, the processing unit 2120 calculates a ratio (R _a ) of the area (A _e ) of the coke region (S _e ) to the area (A _e ) of the carbonization chamber region (S _e ) (see Equation 1).

[Equation 1]

In this way, in calculating the area ratio, after extruding the coke (C) of the carbonization chamber 1110, an empty space is imaged, and on the image image (second image image) captured at this time, the carbonization chamber area S _c The area ratio (R _a ) is calculated using the area (A _c ). In other words, in order to calculate the area (A _e ) of the carbonization chamber region (S _e ), which is an empty space, after extruding the coke (C) of the carbonization chamber 1110, an image is separately captured. This is because the size or volume may be different for each of the plurality of carbonization chambers 1110, and the size or volume may vary according to the number of repetitions of the operation cycle (loading of raw coal-carbonization-extrusion).

And, the higher the calculated area ratio (R _a ), the higher the height (H _c ) of the coke (C), and the smaller the calculated area ratio (R _a ), the lower the height (H _c ) of the coke (C). can judge That is, the height H _c of the coke C may be indirectly detected using the calculated area ratio R _a .

In addition, the processing unit 2120 may quantitatively detect the height (H _c ) of coke using the calculated area ratio (R _a ). At this time, the processing unit 2120 uses a regression equation having the coke height (H _c ) according to the area ratio (R _a ), or uses a data table (date) having the coke height (H _c ) according to the area ratio (R _a ). table), the coke height (H _c ) value can be quantitatively predicted or detected.

In the above, the area of the coke region is calculated on the image image (first image) of the carbonization chamber captured before extrusion, and carbonization, which is an empty space, on the image image (second image) of the carbonization chamber captured after extrusion of the carbonization chamber It has been described that the area ratio is calculated by calculating the area of the real region. However, it is not limited thereto, and the area ratio may be calculated using one image image (first image) taken before extrusion.

More specifically, first, the coke area S _c occupied by coke on the image captured before extrusion (first image image) and the carbonization chamber area S _e , which is the area of the empty space above the coke, are identified. Then, the area (A _c ) of the identified coke region (S _c ) and the area (A _e ) of the carbonization chamber region (S _e ) are calculated. In addition, the sum area (A ce ) is calculated by summing the area (A _c ) _of the coke region (S _c ) and the area (A _e ) of the carbonization chamber region (S _e ). Next, the ratio (R _a ) of the area (A _c ) of the coke region (S _c ) to the total area (A _ce ) is calculated (see Equation 2).

[Equation 2]

Figure 5 (a) is an image image of a plurality of carbonization chambers when coke is sufficiently carbonized, and Figure 5 (b) is an image image of a plurality of carbonization chambers when coke is not sufficiently carbonized. . 6 is a graph showing the area ratio (R _a ) of the coke region according to the temperature of the coke detected by the processing unit according to an embodiment of the present invention. 7(a) is a view for explaining the height of coke after dry distillation is completed in each case where raw coal is insufficiently charged into the carbonization chamber, and FIG.

On the other hand, coke (C) is manufactured by carbonizing raw coal, and contraction of the raw coal occurs during the carbonization process. That is, shrinkage occurs in the process of converting raw coal into coke by heat treatment. Accordingly, comparing (a) and (b) of FIG. 5 , the color representing the temperature of coke, that is, the area of the region indicated by orange, purple, and red, etc., is the case when the coke is sufficiently carbonized (a) and when it is not smaller than in (b). And, as shown in FIG. 5, the height of coke is lower in the case where coke is sufficiently carbonized on the image image (a) than in the case where it is not (b), which has the same tendency even inside the actual carbonization chamber 1110. .

In addition, referring to FIG. 6 , as the temperature of the coke increases, the area ratio R _a of the coke region S _c tends to decrease. This is because, as described above, shrinkage occurs in the process of converting raw coal into coke by heat treatment, and the higher the temperature of the coke, the larger the shrinkage.

Meanwhile, as shown in FIG. 6 , even if the coke temperature is the same, the area ratio (R _a ) of the coke region may be different. For example, looking at the region marked 'F' in FIG. 6, the coke temperature is the same as 500 ° C, but the calculated coke area ratio (R _a ) varies between about 0.64 and 0.75. This may be according to the amount of raw coal charged into the carbonization chamber 1110.

Referring to FIGS. 3 and 7 in more detail, the height H ₁ of the carbonization chamber 1110 is higher than that of the combustion chamber 1120 as described above. Further, in charging the raw coal into the carbonization chamber 1110, it is an appropriate height to charge the raw coal so that the height of the raw coal in the carbonization chamber 1110 becomes the height of the combustion chamber 1120. Also, a reference height (H _s ) may be set using the appropriate height, and the reference height (H _s ) may be set to a range value. That is, the reference height (H _s ) is the height of the combustion chamber (H ₂ ), the height of the lowest limit value that is lower than the height (H ₂ ) of the combustion chamber 1120, and the height of the combustion chamber 1120 (H ₂ ) Higher than It may be set to include the height of the uppermost limit value, which is the height, and have a range greater than or equal to the height of the lower limit value and less than or equal to the height of the uppermost limit value.

However, as described above, since shrinkage occurs in the process of converting coking coal into coke, the height (H _c ) of coke is lower than the height of coking coal before dry distillation. Accordingly, even if raw coal is charged into the carbonization chamber at a standard height (H _s ), the height (H _c ) of coke is lower than the standard height (H _s ) when dry distillation is completed as shown in FIG. 3 (a).

At this time, when the difference between the standard height (H _s ) and the coke height (H _c ) is 10% or less of the standard height (H _s ), it can be determined that the raw coal is charged at the standard height (H _s ) before carbonization. That is, it can be determined that the raw coal is charged within the range of the standard height (H _s ). By the way, when the height of the raw coal charged into the carbonization chamber 1110 is less than the lowest height of the reference height (H _s ) or exceeds the maximum height, the height of coke (H _c ) when dry distillation is completed is shown in FIG. 7 As in (a) and (b), the difference between the reference height (H _s ) and the coke height (H _c ) may exceed 10% of the reference height (H _s ). As such, when the difference between the standard height (H _s ) and the coke height (H _c ) exceeds 10% of the standard height (H _s ), it is judged that the coke was charged outside the range of the standard height (H _s ) before carbonization. can

From this, it can be seen that even if the temperature of the coke at which dry distillation is completed is the same, the height (H _c ) of coke when dry distillation is completed may be different according to the charged amount of raw coal charged into the carbonization chamber 1110. In addition, according to this, even if the temperature (T _p ) of the coke detected by the detection unit 2100 is the same, it can be seen that the area ratio (R _a ) of the coke region (S _c ) calculated by the detection unit 2100 may be different. .

Therefore, the determination unit 2130 first determines whether the coke C is carbonized sufficiently by using the temperature T _p of the coke detected by the processing unit 2120. At this time, when it is determined that the coke C is sufficiently carbonized, it is determined whether the loading amount of coking coal is normal or abnormal using the area ratio (R _a ) of the coke region. However, if it is determined that the coke (C) is not carbonized sufficiently, the determination step using the area ratio (R _a ) of the coke region, that is, the charging amount determination step is not passed and the determination is ended.

The determination unit 2130 determines the dry distillation state of the coke using the temperature (T _p ) of the coke and determines the loading amount of coking coal using the area ratio (R _a ) of the coke region, using FIG. 8 later. It is explained concretely at the time of explanation.

The control unit 2200 controls the operation of at least one of the fuel supply unit 1130 and the charging unit 1200 according to the determination result of the determination unit 2130 . That is, when it is determined that the coke (C) is not carbonized sufficiently in the determination unit 2130, the control unit 2200 is the combustion gas supplied to the carbonization chamber 1110 on at least one side of the corresponding carbonization chamber 1110 for the next operation. The operation of the fuel supply unit 1130 is controlled so that the amount of is increased. In addition, if the determining unit 2130 determines that the amount of raw coal charged is insufficient or excessive, the control unit 2200 controls the operation of the charging unit 1200 so that the amount of raw coal supplied to the corresponding carbonization chamber 1110 is increased in the next operation. do.

8 is for explaining a method of determining whether the dry distillation state of coke is normal or abnormal, a method of determining whether the coking coal loading amount is normal or abnormal, and the operation of the control unit according to the determination result according to an embodiment of the present invention. It is a flow chart.

When the coke temperature (T _p ) is detected in the processing unit 2120 (S10) and the area ratio (R _a ) of the coke region is calculated (S20), the determination unit 2130 first determines whether the coke C is sufficiently carbonized. In other words, it is judged whether carbonization is normal. To this end, the determination unit 2130 compares the temperature of the coke detected by the processing unit 2120 (T _p ) and a preset reference temperature (T _s ) (S100). Here, the reference temperature (T _s ) may be, for example, 450°C to 500°C. Of course, the reference temperature (T _s ) may be variously changed in a temperature range of less than 450 °C and greater than 500 °C.

The determination unit 2130 determines that the coke is sufficiently carbonized in the carbonization chamber 1110 when the predicted coke temperature (T _p ) is greater than or equal to the reference temperature (T _s ) (T _p ≥ T _s ) (Yes) S111). The result of determining the carbonization state of the coke is transmitted to the control unit 2200, and when the control unit 2200 supplies fuel gas to the combustion chamber 1120 for the next operation, the supply condition of the fuel gas supplied to the combustion chamber 1120 for the current charge is The operation of the fuel supply unit 1130 is controlled to be maintained (S112).

However, when the predicted coke temperature (T _p ) is less than the reference temperature (T _s ) (T _p < T _s ) (No), it is determined that the coke is not carbonized sufficiently (S121). This may be because the amount of fuel gas supplied to the combustion chamber 1120 is insufficient. Accordingly, when the result of determining the coke carbonization state is transmitted to the control unit 2200, the control unit 2200 adjusts the operation of the fuel supply unit 1130 so that the supply amount of fuel gas supplied to the combustion chamber 1120 is increased in the next operation ( S122).

If it is determined that the coke (C) is normally carbonized, that is, sufficiently carbonized, the determination unit 2130 determines whether the coke (C) is normally carbonized using the area ratio (R _a ) of the coke region. To this end, the determination unit 2130 determines the first reference ratio (R _s1 ) and the second reference ratio (R _s2 ) having a larger value than the first reference ratio (R _s1 ) and the calculated area ratio (R _a ). Compare (S200).

At this time, when the calculated area ratio (R _a ) is greater than or equal to the first reference ratio (R _s1 ) and less than or equal to the second reference ratio (R _s1 ), the determination unit 2130 inserts raw coal into the carbonization chamber 1110, It is determined that the raw coal is charged at a normal height (S211). That is, it is determined that the charging amount of the raw coal is normal (S211). And, the charging amount normal determination signal is transmitted to the control unit 2200, and the control unit 2200 supplies the charging unit 1200 so that when supplying raw coal to the carbonization chamber 1110 for the next operation, the charging amount supplied in the current operation can be supplied. The operating conditions are maintained (S212).

However, when the calculated area ratio (R _a ) is less than the first reference ratio (R _s1 ), the determination unit 2130 determines that the charging amount of the raw coal is insufficient when charging the raw coal into the carbonization chamber 1110 ( abnormal) (S221). That is, it is determined that the raw coal is charged at a height lower than the normal height (H _s ). This charging amount insufficient determination signal is transmitted to the control unit 2200, and the control unit 2200 controls the operation of the charging unit 1200 to increase the charging amount when supplying raw coal to the carbonization chamber 1110 for the next operation (S222).

As another example, when the calculated area ratio (R _a ) exceeds the second reference ratio (R _s1 ), the determination unit 2130 determines that the charging amount of the raw coal is excessive when charging the raw coal into the carbonization chamber 1110. It is judged (abnormal) (S231). That is, it is determined that the raw coal is charged higher than the normal height (H _s ). This excessive charging amount determination signal is transmitted to the control unit 2200, and the control unit 2200 controls the operation of the charging unit 1200 so that the charging amount is reduced when supplying raw coal to the carbonization chamber 1110 for the next operation (S232).

In the above, the coke temperature (T _p ) and the reference temperature (T _s ) are compared (S100), and before performing the process of determining the coke carbonization state, the coke temperature (T _p ) is detected and the area ratio of the coke area It was explained that the process of calculating (R _a ) was preceded.

However, in the process of calculating the area ratio (R _a ) of the coke region, the coke temperature (T _p ) and the reference temperature (T _s ) are compared (S100), and when the coke carbonization state is determined to be normal (S111), the may be performed later.

Hereinafter, the operation of the raw material processing apparatus according to an embodiment of the present invention will be described using FIGS. 1 to 4 and FIG. 8 . At this time, in calculating the area ratio, using an image captured before extrusion and a captured image after extrusion will be described as an example.

First, raw coal is charged into each of the plurality of carbonization chambers 1110 using the charging unit 1200 . At this time, raw coal may be sequentially charged into the plurality of carbonization chambers 1110 or simultaneously charged.

Then, the fuel gas is supplied to the combustion chamber 1120 located on one side or both sides of each carbonization chamber 1110 by operating the fuel supply unit 1130 . Accordingly, a flame is generated inside the combustion chamber 1120, and the combustion chamber 1120 is heated by the heat of the flame. Accordingly, the raw coal in the carbonization chamber 1110 is heated, that is, carbonized, and thus coke (C) is produced.

In this way, in carbonizing the raw coal in the carbonization chamber 1110 by supplying fuel gas to the combustion chamber 1120, carbonization can be performed sequentially or simultaneously in a plurality of carbonization chambers 1110 arranged in one direction. there is.

When a predetermined time elapses from the point at which carbonization of the raw coal is started, coke (C) is extruded from the carbonization chamber 1110. To this end, the extrusion unit 1300 is moved forward of the carbonization chamber 1110 to be extruded, for example, the first carbonization chamber (hereinafter, the first carbonization chamber 1110). Then, doors provided at one end and the other end of the first carbonization chamber 1110 are opened.

When the door of the first carbonization chamber 1110 is opened, an image of the first carbonization chamber 1110 is captured using the imaging unit 2110 before coke is extruded. Accordingly, for example, a picture image such as any one of (a) to (c) of FIG. 4 is acquired and transmitted to the processing unit 2120 .

When the imaging of the first carbonization chamber 1110 is completed, the coke C in the first carbonization chamber 1110 is extruded. To this end, the extruder 1310 is advanced toward the first carbonization chamber 1110 by operating the extrusion driver 1320 . Accordingly, the head 1311 of the extruder 1310 moves forward through the inlet of the first carbonization chamber 1110, and accordingly, the coke in the first carbonization chamber 1110 is pushed toward the outlet opposite the inlet. And when the head 1311 of the extruder 1310 continues to move forward, the coke C of the first carbonization chamber 1110 is discharged out through the outlet, that is, extruded, which is charged into a bucket located outside the outlet. do.

When the extrusion of coke (C) in the first carbonization chamber 1110 is completed, an image of the first carbonization chamber 1110 is captured using the imaging unit 2110 . Thus, for example, a video image as shown in (d) of FIG. 4 is obtained and transmitted to the processing unit 2120 .

The processing unit 2120 identifies a carbonization chamber area (S _e ) on the captured image of the first carbonization chamber 1110, that is, a pre-extrusion image, and identifies a coke area (S _c ) on the post-extrusion image.

And the processing unit 2120 detects the temperature of the coke by using the coke region (S _c ) identified on the image after extrusion. That is, an average of temperature values of a plurality of pixels included in the identified coke area S _c is calculated, and the result is output as the temperature value of coke. The detected coke temperature (T _p ) is transmitted to the determination unit.

In addition, the processing unit 2120 calculates the area (A _e ) of the carbonization chamber region (S _e ) identified on the image before extrusion and the area (A _c ) of the coke region (S _c ) identified on the image after extrusion. . And, the area ratio (R _a ) of the coke region (S _c ) to the carbonization chamber region (S _e ) (see Equation 1) is calculated. The calculated area ratio (R _a ) of the coke area (S _c ) is transmitted to the determination unit 2130 .

The determination unit 2130 determines whether the coke in the first carbonization chamber 1110 is normally carbonized, that is, sufficiently carbonized, using the coke temperature T _p detected by the processing unit 2120 . To this end, the determination unit 2130 compares the detected temperature of coke (T _p ) and the reference temperature (T _s ) (S100).

At this time, when the detected temperature (T _p ) of the coke is less than the reference temperature (T _s ) (T _p < T _s ) (No), it is determined that the coke (C) is not carbonized sufficiently (S121). In addition, the determination is terminated at the current stage without performing a step of determining whether the loading amount of coking coal is normal. In addition, the control unit 2200 adjusts the operation of the fuel supply unit 1130 so that the supply amount of fuel gas is increased when supplying fuel gas to the combustion chamber 1120 in the next operation according to the determination result (S122).

As another example, when the temperature of the detected coke (T _p ) is greater than or equal to the reference temperature (T _s ) (T _p ≥ T _s ) (Yes), it is determined that the coke is sufficiently carbonized in the carbonization chamber 1110 (S111). This determination signal is transmitted to the control unit 2200, and when the control unit 2200 supplies fuel gas to the combustion chamber 1120 in the next operation, the combustion chamber 1120 on one side or both sides of the first carbonization chamber 1110 in the current operation The operation of the fuel supply unit 1130 is controlled so that the supply amount of the fuel gas supplied to is maintained (S111).

And, when it is determined that the coke (C) is normal, that is, sufficiently carbonized, the determination unit 2130 uses the area ratio (R _a ) of the coke area to determine whether the charging amount of the raw coal supplied to the carbonization chamber 1110 is normal. judge whether That is, it is determined whether the height of the raw coal supplied to the carbonization chamber 1110 before carbonization is charged within the reference height (H _s ) range. To this end, the determination unit 2130 determines the first reference ratio (R _s1 ) and the second reference ratio (R _s2 ) having a larger value than the first reference ratio (R _s1 ) and the calculated area ratio (R _a ). Compare (S200).

At this time, when the calculated area ratio (R _a ) is greater than or equal to the first reference ratio (R _s1 ) and less than or equal to the second reference ratio (R _s1 ), the determination unit 2130 inserts raw coal into the carbonization chamber 1110, It is determined that the raw coal is charged in a normal amount (S211). In other words, it is determined that the raw coal is charged so that the height of the raw coal is within the range of the reference height (H _s ). In addition, the control unit 2200 maintains operating conditions of the charging unit 1200 so that the current charging amount can be supplied when supplying raw coal to the first carbonization chamber 1110 in the next operation according to the determination result. (S212).

However, when the calculated area ratio (R _a ) is less than the first reference ratio (R _s1 ) or exceeds the second reference ratio (R _s1 ), it is determined that the charging amount of the coking coal is insufficient or excessive (S221, S231). That is, it is determined that the height of the raw coal supplied to the carbonization chamber 1110 before carbonization is charged to a height less than the lowest height of the reference height (H _s ) or to exceed the maximum height. Accordingly, when supplying raw coal to the first carbonization chamber 1110 in the next operation, the control unit 2200 controls the operation of the charging unit 1200 to increase (S222) or decrease (S232) the charging amount.

While determining the carbonization state of the coke carbonized in the first carbonization chamber 1110 and the charging state of raw coal into the first carbonization chamber 1110 using the image image taken in the first carbonization chamber 1110, the extrusion unit (1300) moves to the front of another carbonization chamber, for example, the second carbonization chamber 1110 located on the right side of the first carbonization chamber 1110.

Then, in the same way as the above-described method, the second carbonization chamber 1110 is imaged and coke is extruded. That is, before extruding the coke (C), the imaging unit 2110 images the second carbonization chamber 1110, and then the extruder 1310 extrudes the coke (C) in the second carbonization chamber 1110, and then The imaging unit 2110 captures an image of the extruded second carbonization chamber 1110 . Then, in the same way as the above-described method, the coke temperature (T _p ) and the area ratio (R _a ) of the coke region (S _c ) are calculated using the image of the second carbonization chamber 1110, and the coke The dry distillation state and the loading state of coking coal in (C) are judged.

This process is performed for each of the remaining carbonization chambers 1110, and may be sequentially performed for the carbonization chambers 1110 arranged in one direction.

In this way, according to the embodiments, the height H _c of coke can be detected using an image of the carbonization chamber 1110 captured. That is, the height of coke (H _c ) can be indirectly detected using the area ratio (R _a ) of the coke region (S _c ) on the image image. Therefore, the operator can safely detect the height of the coke without being exposed to high heat.

In addition, it is possible to know whether the carbonization state of the coke is normal or not, using the coke temperature (T _p ) and the area ratio (R _a ) of the coke region (S _c ) detected using the image image, and the raw coal is the standard. It can be known whether or not it is loaded at the height (H _s ). In addition, the amount of fuel gas supplied to the combustion chamber 1120 and the amount of raw coal charged to the carbonization chamber 1110 may be adjusted according to the identified carbonization state of coke and the amount of raw coal charged. Accordingly, it is possible to prevent defects from occurring due to insufficient dry distillation of coke (C), and it is possible to prevent production from being reduced due to insufficient loading of coking coal.
