[0001] APPARATUS AND METHOD FOR COOLING THE SUBJECT [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device and a cooling method, and more particularly, to a cooling device and a cooling method capable of improving cooling efficiency by separating a foreign substance in a cooling medium and a cooling medium.

Generally, the red gelled coke in the coke oven is loaded by the extruder while being pushed by the fire extinguisher. When a certain amount of glowing coke is loaded on a fire extinguisher, the fire extinguisher carries along the rail, transfers the glow coke to the fire extinguisher, and extinguishes the glow coke by spraying the fire extinguisher in the fire extinguisher.

Conventionally, the digested water injected with the red coke was again collected and passed through the sedimentation section, and then supplied to the digested water tank for recycling. However, in the settling section, the unreacted fractional coke may be transferred to the digester tank together with the digested water and sprayed with the red coke. Particulate coke sprayed with fire water comes into contact with high temperature coke of hot red, and it burns with water vapor to the atmosphere and causes environmental pollution. In addition, a part of the minute coke which is not burned is adsorbed on the red coke to generate ash, and the air permeability of the red coke is lowered and the digestion efficiency is lowered.

In addition, the digested water that is recycled has a high temperature by recovering heat in the course of extinguishing the glow-colored coke. The temperature of the extinguished water changes due to the number of digestions per hour due to the coke oven utilization rate, the waiting time during digestion, Therefore, since the temperature of the extinguishing water changes every time the extinguishing operation is carried out, the quality of the produced coke may be varied. In addition, if fire extinguishing water having a temperature of about 40 to 50 degrees Celsius is applied to a red coke having a temperature of about 1100 degrees Celsius, cracking will occur in the coke due to rapid cooling with a large temperature difference, so that the strength of the coke may be lowered and the moisture content of the coke may increase.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. To illustrate the invention in detail, the drawings may be exaggerated and the same reference numbers refer to the same elements in the figures.

FIG. 1 is a schematic view of a cooling apparatus according to an embodiment of the present invention, FIG. 2 is a view showing a storage unit according to an embodiment of the present invention, and FIG. 3 is a view showing the operation of a discharge pipe according to an embodiment of the present invention FIG. 4 is a view showing an operation of a steam injector according to an embodiment of the present invention, and FIG. 5 is a flowchart showing a cooling method according to an embodiment of the present invention.

The cooling device according to the embodiment of the present invention includes a spraying part 100 for spraying a cooling medium to a material to be processed, a sprinkling part 100 for collecting the cooling medium sprayed from the spraying part 100, And a storage part 300 connected to one side of the injection part 100 and the other side of which is connected to the sinking part 200. At this time, the object to be treated may be a red coke, the foreign matter may be a minute coke, and the cooling medium may be cooling water.

First, the process of injecting cooling water into the red coke to understand the present invention will be described. The gypsum coke oven (not shown), which is in the coke oven (not shown), is loaded into the fire extinguisher 20 by an extruder. When a certain amount of the red coke is loaded in the fire extinguisher 20, the fire extinguisher 20 moves along the rails to transfer the red coke to the fire extinguisher 10 and the cooling water is sprayed from the fire extinguisher 10 to cool the heat coke .

The cooling water injected into the red coke is collected by the collection line 700 and supplied to the storage part 300 through the sink part 200 to be recycled. However, the minute coke not precipitated in the settling portion 200 may be moved to the storage portion 300 together with the cooling water, and then may be injected into the red coke. In addition, the temperature of the cooling water varies depending on the working conditions and the environment, and thus the quality of the produced coke may be varied. Therefore, the cooling device according to the embodiment of the present invention effectively separates the cooling water and the foreign matter in the cooling water, and the temperature of the cooling water can be raised to a certain temperature.

Hereinafter, a cooling apparatus according to an embodiment of the present invention will be described in detail. 1, the cooling apparatus includes a spraying unit 100, a sinking unit 200, and a storage unit 300, and includes a steam spraying unit 500, a control unit 600, and the spraying unit 100, The storage unit 300, and the lines 400, 700, and 800 that connect the storage unit 300 to the settling unit 200.

The jetting section (100) serves to jet the cooling water to the red coke disposed in the fire extinguisher (10) and transferred into the fire extinguisher (10). The jetting section (100) can be located above the fire extinguisher (20) and injects cooling water from the upper part to the lower part. The jetting section 100 may include a plurality of nozzles or may include a plurality of jetting holes (not shown) to jet the cooling water. However, the present invention is not limited to this, and cooling water may be injected at various positions in various ways.

The sedimenting unit 200 includes a sedimentation tank 210 forming a space for accommodating the cooling medium and a cover 220 covering the upper part of the sedimentation tank 210.

The settling tank 210 may be formed to have an inner space, and the inner space may be divided into two regions through the dam 230. One area is connected to the collection line 700. One end of the collecting line 700 is connected to the lower side of the fire extinguisher 10 and the other end is connected to the settling tank 210 to collect the cooling water injected into the red coke and move it to the settling tank 210. The cooling water that has moved to the settling tank 210 is stored in a stopped state in one region, and the heavy one-component coke sinks downward over time. When the cooling water separated from the coke oven is stored over a predetermined amount, the water level of the water is higher than the dam 230 and moves to the other region of the sedimentation tank 210 beyond the dam 230.

That is, the heavy coke is submerged in one region of the sedimentation tank 210, and the light cooling water is stored in the other region of the sedimentation tank 210 beyond the dam 230 as the storage amount is increased, thereby separating the coke and the cooling water. However, since the upper part of the settling tank 210 is open, when cooling water containing too much minute coke is supplied at a time in the case of rain or in the settling tank 210, there is not enough time for the minute coke to settle, The minute coke may be introduced together with the cooling water into the other region of the cooling pipe 210. Therefore, an operation for separating the cooling water and the partial coke needs to be additionally performed.

The cover 220 is formed so as to cover the upper part of the settling tank 210. The cover 220 covers the upper part of the settling tank 210 to reduce the temperature change of the cooling water in the settling tank 210 due to contact with the outside and prevent the inflow of the rain into the settling tank 210. In addition, a door (not shown) may be provided at one end of the cover 220 or the settling tank 210 to perform an operation for discharging a predetermined amount or more of coke in one region of the settling tank 210. Therefore, it is possible to close the door at normal times, to open the door at the time of discharging the minute coke, and to perform the minute coke collecting work in the settling tank 210 using a crane or the like. However, the structure of the settling tank 210 or the cover 220 is not limited to this and may vary.

2, the storage unit 300 includes a container 310 having a cylindrical inner space, at least a portion of which is narrower toward the lower side, and a container 310 disposed to be inclined downward toward the inner wall of the container 310 And an inlet 320. Further, it may further include a discharge pipe 330, a level sensor 340, a temperature sensor 350, and an overflow pipe 360.

The container 310 may be formed in a conical shape in which the upper portion is formed in a cylindrical shape and the lower portion thereof is narrowed in the downward direction. Thus, an angle may not be formed around the space inside the container 310. For example, when the container is formed in a rectangular tube shape, angles may be formed at four portions around the container. Therefore, when the cooling water is sprayed toward the inner wall surface of the container, the cooling water collides with the angled portion of the container and can not move along the circumference of the container and can move downward. Accordingly, the cooling water does not rotate in the vessel, and the cooling water and the minute coke are not separated.

Therefore, the periphery of the vessel 310 may be formed in a circular or elliptical shape so that angled portions are not formed so that the cooling water can move and rotate along the inner circumference of the vessel 310. [ However, the shape and structure of the container 310 are not limited thereto, and the container 310 may be formed in various shapes such as a conical shape as a whole.

The inlet 320 passes through the container 310 at one end and is connected to the inlet line 800 at the other end. The inlet line 800 has one end connected to the inlet 320 and the other end connected to the settling tank 210. In particular, the inlet 320 may be provided on top of the vessel 310. For example, the inflow unit 310 may be provided on a narrower portion of the container 310, that is, on the upper portion, that is, a cylindrical portion, rather than a conical portion. Accordingly, the cooling water can be moved from the upper portion of the vessel 310 to the lower portion thereof to rotate the cooling water, thereby securing a sufficient height for separating the cooling water and the partial coke.

At this time, the inflow line 800 is connected to another region of the settling tank 210, that is, a region where the separated coke and the separated cooling water are stored, and a pump is provided to supply the cooling water in the settling tank 210 to the inflow unit 320 . The inflow line 800 is connected to the upper part of the sedimentation tank 310, that is, above the part where the minute coke is accumulated in the sedimentation tank 310. Therefore, it is possible to prevent the minute coke from flowing together when the cooling water is sucked in the inflow line 800.

The inlet 320 may also be arranged such that the end is exposed to the interior of the container 310 and tilted downwardly, for example, by about 15 degrees, toward the interior wall of the container 310. Accordingly, when the inflow pipe 320 blows the cooling water, the cooling water is stored in the container 310 while rotating downward along the wall surface of the container 310. At this time, as the cooling water rotates, the minute coke having a heavy weight collects toward the central portion of the vessel 310, and the cooling water rotates along the wall surface of the vessel 310, so that the cooling water and the minute coke are separately stored.

That is, the heavy coke having a heavy weight is gathered at the lowermost portion on the center side in the vessel 310, and the cooling water moves along the edge of the inside of the vessel 310 and is collected at the upper portion of the partial coke. However, the position and angle of arrangement with the structure of the inlet device 320 are not limited thereto, and may be provided inside the container 310, or may be in communication with the interior of the container 310 or may vary.

One end of the discharge pipe 330 is connected to the lower portion of the container 310 to which a first pipe 410 to be described later is connected and the other end is connected to the settling portion 210, Thereby forming a path. The first pipe (410) serves to suck the separated cooling water from the minute coke. Since the minute coke in the vessel 310 is stored in the lowermost part of the vessel 310 and the cooling water is stored in the upper part of the partial coke, the discharge pipe 330 for discharging the minute coke is connected to the first pipe 410 through which the cooling water is sucked, And is connected to the lower portion of the container 310. [ Accordingly, the discharge pipe 330 communicates with the lowermost part of the container 310, that is, the area where the minute coke in the container 310 is stored.

Further, the discharge pipe 330 may be connected to one area of the settling tank 210, that is, a region where the cooling water and the partial coke are separated. If the partial coke is stored in one area of the settling tank 210 and the partial coke is collected over a predetermined amount, the partial coke can be treated by performing a partial coke collecting operation using a crane or the like.

The discharge pipe 330 is provided with a discharge valve 331 for opening and closing the movement path. Accordingly, when the discharge valve 331 is opened as shown in FIG. 3, the minute coke in the container 310 moves along the discharge pipe 330 and is discharged to the settling tank 210 and stored. When the discharge valve 210 is kept in the open state, the cooling water is discharged after the minute coke is discharged and the cooling water can not be stored in the container 310. Therefore, after discharging the minute coke, the discharge valve 331 is closed, It is possible to prevent the cooling water from being discharged from the discharge port 310. However, the structure of the discharge pipe 330 and the position connected to the container 310 or the sedimenting unit 200 are not limited thereto and may vary.

The container 310 may be provided with a level sensor 340 and disposed between the first pipe 410 and the discharge pipe 330 to be described later and serves to sense the height of the minute coke. That is, since the first pipe 410 sucks the cooling water separated from the minute coke, the minute coke should not be introduced.

The level sensor 340 is provided between the discharge pipe 330 provided at the lowermost part of the vessel 310 and the first pipe 410 so that before the height of the minute coke rises to the first pipe 410, Should be detected. Thus, when the height of the minute coke is increased to the level sensor 340, the discharge pipe 330 is opened and the minute coke in the container 310 is discharged to prevent the minute coke from flowing into the first pipe 410 .

In addition, the container 310 may be provided with a temperature sensor 350, and the container 310 serves to measure the temperature of the cooling water stored therein. The steam injector 500, which will be described later, injects steam into the vessel 310 to raise the temperature of the cooling water. Accordingly, the temperature of the cooling water can be increased through the temperature sensor 310 to a desired temperature while measuring the temperature of the cooling water.

The container 310 may be provided with an overflow pipe 360. The overflow pipe 360 may have one end connected to the upper portion of the vessel 310 and the other end connected to the settling tank 210. The overflow pipe 360 supplies the cooling water to the settling pipe 210 to lower the water level of the cooling water in the container 310 when the cooling water is supplied in an excessive amount to the overflow pipe 360, . Therefore, it is possible to prevent the container 310 from being damaged by the cooling water supplied in excess.

The connecting line 400 connects the jetting unit 100 and the storage unit 300. The connection line 400 includes a first pipe 410 connected to the container 310 and disposed to be inclined downwardly, a second pipe 420 formed in a ring shape and having one side connected to the first pipe 410, And a third pipe 430 having one end connected to the other end of the second pipe 420 and the other end connected to the injection unit 100.

A plurality of first pipes 410 may be provided, one end of which is connected to the container 310 and the other end of which is inclined downward and connected to a second pipe 420 to be described later. The first pipe 410 may be arranged such that a plurality of the first pipes 410 are inclined in the same direction, for example, the same direction as the direction in which the inflow unit 320 is tilted. When the cooling water is introduced into the first pipe 410, the cooling water is sucked along the inclined direction of the first pipe 410, so that the cooling water is sucked into the first pipe 410 It rotates by the flow.

Since the cooling water is collected toward the center side in the container 310 and the cooling water is rotated on the edge side along the wall surface of the container 310, (410) connected to the edge of the first pipe (410).

The second tube 420 is formed in a ring shape and arranged in a lateral direction, and an upper portion is connected to the first tube 410. That is, the second pipe 420 is spaced from the periphery of the discharge pipe 330 to surround the discharge pipe 330 and collect the cooling water sucked into the plurality of first pipes.

The third pipe 430 has one end connected to the second pipe 420 and the other end connected to the injection unit 100. The third pipe (430) is provided with a control valve (431) to control the amount of cooling water supplied to the sprayer (100). When the control valve 431 is opened, the cooling water in the container 310 flows into the first pipe 410, passes through the second pipe 420 and the third pipe 430, is supplied to the jetting unit 100, It is sprayed on the coke. When the control valve 431 is closed, the cooling water in the vessel 310 is stopped from flowing into the first pipe 410, and the supply of the cooling water to the jetting section 100 is stopped.

Since the cooling water in which the minute coke is separated into the first pipe 410, the second pipe 420 and the third pipe 430 moves, the first pipe 410, the second pipe 420, The second tube 420, and the third tube 430 can be prevented from being damaged. However, the shapes and connection structures of the first pipe 410, the second pipe 420, and the third pipe 430 are not limited to these and may vary.

1 and 4, the steam injector 500 is connected to the vessel and serves to inject steam into the vessel. The steam injector 500 includes a steam line 510 for supplying steam, a steam valve 520 for adjusting the amount of steam supplied to the steam line 510, And a steam injector 530 connected to the inside of the vessel 310 at the other side thereof.

The steam line 510 serves to supply the high-temperature steam to the steam injector 530. The steam line 510 is provided with a steam valve 520 to control the amount of steam supplied to the steam injector 530. When the steam valve 520 is opened, high temperature steam is supplied to the steam injector 530, and the steam is injected into the container 310. When the steam valve 520 is closed, the supply of steam to the steam injector 530 is stopped The steam injection into the vessel 310 is stopped.

For example, the temperature of the cooling water injected into the glowing coke needs to be 80 to 95 degrees Celsius. That is, the temperature of the cooling water can be increased to 95 degrees Celsius or less, which is the temperature at which the cooling water is evaporated, and the temperature difference between the coke and the red coke can be reduced. Accordingly, it is possible to control the operation of the steam valve 520 to inject steam in the vessel 310 and raise the temperature of the cooling water to 80 degrees Celsius or more. Then, the temperature of the cooling water is monitored through the temperature sensor 350, and when the temperature of the cooling water exceeds 95 degrees Celsius, the steam valve 520 is controlled to stop the steam injection in the vessel 310.

Accordingly, the temperature of the cooling water can be kept constant at every time the cooling water is sprayed, and it is possible to minimize the variation in the quality of the coke due to the cooling water temperature deviation. In addition, by minimizing the temperature difference between the cooling water and the glowing coke, it is possible to prevent quenching of the coke, improve the strength of the coke, and reduce the water content, thereby producing high quality coke. However, the controlled temperature range of the cooling water is not limited to this and may vary.

The steam injector 530 includes a body 531 formed in a ring shape and arranged to surround the periphery of the vessel 310 and a steam supply pipe 533 having one end connected to the body 531 and the other end connected to the vessel 310 And an injection unit 532.

The body 531 is disposed to surround the periphery of the container 310 and the periphery of the container 310. Inside the body 531, a space through which steam can move is formed and connected to the steam line 510 to receive high temperature steam.

A plurality of steam injection units 532 may be provided and arranged radially. The steam injection unit 532 is connected to the body 531 and the vessel 310 to inject the high temperature steam moving in the body 531 into the vessel 310. At this time, since the steam injection unit 532 is disposed radially toward the center of the vessel 310, steam can be uniformly injected into the vessel 310. Accordingly, it is possible to reduce the occurrence of a temperature variation depending on the region in which the cooling water in the vessel 310 is stored.

A heating unit (not shown) may be provided in place of the steam injection unit 500 to increase the temperature of the cooling water. The heating portion may include a heating wire (not shown) disposed to surround at least any one of the inside of the container 310, the inside of the wall of the container 310, or the outside of the container 310. Accordingly, when electricity is supplied to the hot wire, the temperature of the hot wire rises, so that the cooling water in the container 310 can be heated and the temperature of the cooling water can be raised. Therefore, by controlling the amount of electricity supplied to the hot wire, the cooling water can be raised to a desired temperature. Further, it is possible to carry out the warming operation of the cooling water in the vessel 310 with the heat wire. However, the method of raising the temperature of the cooling water is not limited to this and may vary.

Referring to FIG. 1, a control unit 600 is connected to the temperature sensor 350 and the level sensor 340 and controls operation of the steam valve 520 and the discharge valve 331. For example, the control unit 600 can control the operation of the discharge valve 331 by checking the height of the minute coke while exchanging signals with the level sensor 340.

The control unit 600 checks the height of the minute coke when the discharge valve 331 is closed and opens the discharge valve 331 when the height of the stored minute coke reaches the level sensor 340, So that the minute coke can be discharged to the sedimentation paper 310. After discharging the minute coke, the control unit 600 may lock the discharge valve 331 and store the separated coke and the separated cooling water in the container 310. Accordingly, it is possible to prevent the coke from flowing into the first pipe 410 and re-mixing the coke into the cooling water separated from the coke oven and injecting the coke into the coke oven.

Meanwhile, the control unit 600 can check the temperature of the cooling water while exchanging signals with the temperature sensor 350, thereby keeping the temperature of the cooling water constant. That is, when the set temperature range, for example, 80 to 95 degrees, is input to the controller 600, the controller 600 controls the operation of the steam injector 500 to keep the temperature of the cooling water within the set range have. If the temperature of the cooling water measured by the temperature sensor 350 is less than 80 degrees Celsius, the steam injector 500 is controlled to inject hot steam into the container 310. If the temperature of the cooling water exceeds 95 degrees Celsius, The steam injection into the vessel 310 can be stopped by controlling the steam generator 500.

Accordingly, the temperature of the cooling water can be kept constant at every time the cooling water is sprayed, and it is possible to minimize the variation in the quality of the coke due to the cooling water temperature deviation. In addition, by minimizing the temperature difference between the cooling water and the glowing coke, it is possible to prevent quenching of the coke, improve the strength of the coke, and reduce the water content, thereby producing high quality coke. However, the controlled temperature range of the cooling water is not limited to this and may vary.

Hereinafter, a cooling method according to an embodiment of the present invention will be described. Referring to FIG. 5, a cooling method according to an embodiment of the present invention includes a step of spraying a cooling medium to a material to be treated (S100), a step of collecting the cooling medium, moving the cooling medium to a settling tank, (S300) of moving the cooling medium in the settling tank to the container, separating the cooling medium from the cooling medium by rotating the cooling medium along the inner wall of the container (S300), and moving the cooling medium in the container (S400) of spraying the processed water. At this time, the foreign matter may be a minute coke, and the cooling medium may be cooling water.

The gypsum coke which has been dried in the coke oven is pushed to the digester 20 by the extruder and loaded. The fire extinguisher 20 moves along the rail to transfer the cryogenic coke to the fire extinguisher 10 and the cooling water is discharged from the fire extinguisher 100 in the fire extinguisher 10 Cool the red coke by spraying.

The injected cooling water is collected by the collecting line 700 and sent to the settling tank 210. When the cooling water is stored in the sedimentation tank 210 for a long time, the heavy coke having a heavy weight sinks to the lower side and the primary coke and the cooling water are firstly separated. Then, the cooling water separated from the minute coke is sent to the vessel 310 through the inflow line 800.

Since the cooling water is supplied into the container 310 by the inflow unit 320 disposed at an inclined downward direction toward the inner wall of the container 310, . As the cooling water is rotated, the heavy coke having a heavy weight collects toward the central portion of the container 310, and the cooling water rotates along the wall surface of the container 310, so that the cooling water and the minute coke are separated and stored. That is, the heavy coke having a heavy weight is gathered at the lowermost portion on the center side in the vessel 310, and the cooling water moves along the edge of the inside of the vessel 310 and is collected at the upper portion of the partial coke.

Then, the controller 600 senses the height of the minute coke in the container 310 through the level sensor 340. If the height of the minute coke does not reach the level sensor 340, the control unit 600 keeps the discharge valve 331 in a locked state, and the amount of the cooling water and the minute coke is increased by the cooling water supplied into the container 310. Thus, if the minute coke in the vessel 310 is higher than the predetermined height, it is discharged to the outside of the vessel 310.

The control unit 600 opens the discharge valve 331 to connect the minute coke to the lower portion of the container 310. When the height of the minute coke reaches the level sensor 340, And is sent to the settling tank 210 through the discharge pipe 330. Accordingly, the height of the minute coke is excessively increased, and the minute coke can be prevented from being sucked into the first pipe 410 through which the cooling water separated from the minute coke is sucked.

The first pipe 410 may be arranged such that a plurality of the first pipes 410 are inclined in the same direction, for example, the same direction as the direction in which the inflow unit 320 is tilted. When the cooling water is introduced into the first pipe 410, the cooling water is sucked along the inclined direction of the first pipe 410, so that the cooling water is sucked into the first pipe 410 It rotates by the flow. Since the cooling water is collected toward the center side in the container 310 and the cooling water is rotated on the edge side along the wall surface of the container 310, (410) connected to the edge of the first pipe (410).

The cooling water separated from the two minute cokes is supplied to the jetting unit 100 through the first pipe 410, the second pipe 420 and the third pipe 430, It is sprayed with coke to cool the gypsum coke. Accordingly, it is possible to prevent the minute coke from being discharged into the atmosphere while being sprayed with the hot coke of the high temperature together with the cooling water, and to prevent the deterioration of the air permeability due to the partial unburned coke attached to the coke. In addition, it is possible to prevent the connection line 400 on which the cooling water moves, from being worn by the minute coke moving together with the cooling water.

In addition, the controller 600 can detect the temperature of the cooling water in the container 310 through the temperature sensor 350 after the second cooling water and the minute coke are separated. When the temperature of the cooling water is lower than the set temperature range, the heat energy is supplied. If the temperature of the cooling water is higher than the set temperature range, the supply of heat energy is stopped to adjust the temperature of the cooling water. For example, the control unit 600 may control the operation of the steam spraying unit 500 so that the temperature of the cooling water is within the set range.

If the temperature of the cooling water measured by the temperature sensor 350 is less than 80 degrees Celsius, the steam injector 500 is controlled to inject hot steam into the container 310. If the temperature of the cooling water exceeds 95 degrees Celsius, The steam injection into the vessel 310 can be stopped by controlling the steam generator 500. Or the inside of the vessel 310 may be heated through the heating unit. However, the method of supplying thermal energy into the container 310 is not limited to this, and may vary.

Accordingly, the temperature of the cooling water can be kept constant at every time the cooling water is sprayed, and it is possible to minimize the variation in the quality of the coke due to the cooling water temperature deviation. In addition, by minimizing the temperature difference between the cooling water and the glowing coke, it is possible to prevent quenching of the coke, improve the strength of the coke, and reduce the water content, thereby producing high quality coke. However, the controlled temperature range of the cooling water is not limited to this and may vary.

Although the present invention has been described in detail with reference to the specific embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims, as well as the appended claims.
