Description

Technical Field

[0001] The present disclosure relates to an apparatus and method for sealing a coke oven door. Background Art

[0002] A coke oven is a facility that produces red-hot coke by applying high-temperature heat to the coal in the carbonization chambers for a predetermined period of time to remove impurities. Coke is a fuel with a high carbon content and trace amounts of impurities, and is typically made from coal. Coke produced from coal can be gray and hard and porous.

[0003] In the process of making coke, fuel coal can be supplied to the carbonization chamber through an inlet in the upper part of each of the carbonization chambers, and the red-hot coke that has undergone dry distillation can be loaded into the digester through an area where the door is opened and can be transported to a processing location.

[0004] The coke oven may include doors for coal inflow and coke discharge, and each door may be operated by the desorption device to open or close a corresponding carbonization chamber.

[0005] During the red-hot coke drying process, coke oven gas (COG), which is impurities containing gaseous components, may be generated in the carbonization chamber. The gas should not leak to the outside through the door, but because the interior of the carbonization chamber is a high-temperature and high-pressure environment, gas may leak from the upper inlet, extrusion side door, or coke side door.

[0006] In particular, a large amount of foreign matter (such as tar, carbon) generated during the coke production process may be deposited on surfaces of the door and the door frame, and airtightness of the coke oven may be impaired due to the deposited foreign matter.

[0007] Therefore, high-temperature gas may leak to the outside of the coke oven and may cause damage and deformation of various facilities, and there may be environmental pollution problems such as deterioration of air quality, and workers may be exposed to accident risks such as burns, gas poisoning, falls and entrapment.

[0008] Typically, workers are available in a service vehicle that can be moved directly to the area of ​​the gas leak and can seal the leak.

[0035] Figure 1 is a diagram illustrating components of an apparatus for sealing a coke oven door according to an embodiment of the present disclosure.

[0036] Reference Figure 1 The apparatus 100 for sealing a coke oven door can be applied to a location where a plurality of coke ovens 10 are provided. The apparatus 100 for sealing a coke oven door can prevent and block gas leakage by sealing an area where gas leakage occurs in the plurality of coke ovens 10.

[0037] Gas leakage may occur in the gap between the oven door and the oven frame of the coke oven 10. Causes of the gas leakage may include deterioration of the oven door due to long-term use, shape deformation due to physical impact caused by opening and closing the oven door, or widening of the gap due to tar generated by coal fixed and solidified between the oven door and the oven frame.

[0038] Generally, an operator who directly rides a service vehicle can move to a gas leakage area and perform an operation to seal the gas leakage point. The present disclosure can provide an apparatus and method for blocking and preventing gas leakage occurring in a coke oven by using a robot without sending an operator to the site.

[0039] Reference Figure 1 and Figure 2a , the apparatus 100 for sealing a coke oven door may include a sealing material supplying unit 110 , a robot 120 , and a moving unit 130 .

[0040] Figure 2b is an enlarged view illustrating a sealing material supply unit 110 and a robot 120 of an apparatus 100 for sealing a coke oven door according to an embodiment of the present disclosure. Figure 1 、 Figure 2a and Figure 2b The components of the apparatus 100 for sealing a coke oven door are described in detail.

[0041] The sealing material supply unit 110 may include a nozzle 111 and a supply line 112 .

[0042] The nozzle 111 can discharge the sealing material. The sealing material can be used to hermetically seal a gas leak point of a coke oven. For example, the sealing material can be used to seal the area between the oven door and the frame of the coke oven.

[0043] The sealing material may be discharged from the nozzle 111 in a semi-solid state. The sealing material may include a thermosetting material that has a semi-solid state at a specific temperature or lower and is cured by high-temperature heat. For example, the sealing material may include one or more materials selected from ceramic clay rock and mortar.

[0044] The sealing material discharged from the nozzle 111 can be cured by the heat generated in the coke oven, thereby sealing the edge of the oven door. The edge of the oven door can be sealed by the cured sealing material, thereby preventing gas leakage.

[0045] The supply line 112 may be connected to the nozzle 111 and may supply the sealing material to the nozzle 111 .

[0046] The robot 120 may include a robot arm 121 and a base 122 .

[0047] The robot arm 121 may be connected to the sealing material supply unit 110 and may support at least a portion of the sealing material supply unit 110 .

[0048] For example, robotic arm 121 may support supply line 112 .

[0049] The robot arm 121 can move the position of the nozzle 111. The robot arm 121 may include, for example, one or more joints, and the position and angle of the end portion may be freely adjusted.

[0050] The nozzle 111 for discharging the sealing material may be provided adjacent to the end of the robot arm 121. Therefore, the apparatus 100 for sealing the coke oven door may move the position of the nozzle 111 by controlling the coordinates of the end of the robot arm 121.

[0051] Specifically, the apparatus 100 for sealing a coke oven door may further include a control unit for controlling the robot arm 121. The control unit may control the robot arm 121 so that the nozzle 111 may move along the edge of the oven door of one of the plurality of coke ovens 10.

[0052] The base 122 may be connected to a lower portion of the robot arm 121 and may support the robot arm 121 .

[0053] The moving unit 130 may move the robot 120 using one or more motors.

[0054] The moving unit 130 may move the robot in a horizontal direction and a vertical direction. Here, the horizontal direction may be a direction in which the plurality of coke ovens 10 are arranged, and the vertical direction may be a length direction of the plurality of coke ovens 10.

[0055] The moving unit 130 may include a frame unit 131, a support unit 132, and a sensing unit 133. The support unit 132 may support the base 122 of the robot 120 from below and may also be connected to the frame unit 131.

[0056] The frame unit 131 may be movable in a horizontal direction. The frame unit 131 may allow the robot 120 to move in a wide area by moving in the horizontal direction in which a plurality of coke ovens are arranged.

[0057] Therefore, when the frame unit 131 moves in the horizontal direction, the support unit 132 connected to the frame unit 131 and the robot 120 provided on the support unit 132 may move together in the horizontal direction.

[0058] The support unit 132 may move in the vertical direction along the length direction of the frame unit 131. When the support unit 132 moves in the vertical direction, the robot 120 provided on the support unit 132 may move in the vertical direction together.

[0059] The sensing unit 133 may include one or more sensors. The sensing unit 133 may sense positions of the frame unit 131 and the support unit 132 for the plurality of coke ovens 10 .

[0060] The sensing unit 133 may identify pillars located on both sides of the oven door. The sensing unit 133 may derive the horizontal position of the frame unit 131 based on the number of pillars identified when the frame unit 131 moves in the horizontal direction.

[0061] For example, when the frame unit 131 stops moving after the sensing unit 133 identifies three pillars while the frame unit 131 moves in the horizontal direction, the position of the frame unit 131 in the horizontal direction can be derived as the frame unit 131 is oriented from the reference position toward the coke oven located at the third position.

[0062] In another embodiment, the sensing unit 133 may identify an identification code of each of the plurality of coke ovens 10. The sensing unit 133 may derive the position of the frame unit 131 in the horizontal direction based on the identified identification code of the coke oven.

[0063] In addition, the sensing unit 133 may derive the position of the support unit 132 in the vertical direction based on the length of the section in which the support unit 132 moves up and down.

[0064] The plurality of coke ovens 10 can be divided into a plurality of sealed areas. Figure 3 As illustrated in , a plurality of coke ovens 10 may be arranged in a horizontal direction, wherein pillars 11 are located between the plurality of coke ovens 10 , and one surface of each coke oven 10 may be divided into a plurality of sealing areas.

[0066] The moving unit 130 can move the robot 120 to the operation target area. The operation target area can indicate the area where the gas leakage occurs in the plurality of sealing areas. The operation target area can be determined by, for example, information about the furnace door and information about the section of the corresponding furnace door.

[0067] The moving unit 130 may move the robot 120 to the operation target area by, for example, moving the frame unit 131 in the horizontal direction and moving the support unit 132 in the vertical direction.

[0068] The robot 120 may move to the vicinity of the operation target area through the moving unit 130 and may perform a sealing operation with respect to the operation target area.

[0069] Reference Figure 2b The robot 120 may further include a laser generator 123 for generating a laser beam. The laser generator 123 may be provided at the end of the robot arm 121, for example.

[0070] The apparatus 100 for sealing a coke oven door according to the present disclosure may detect the edge of the oven door using an edge tracking technology using a laser generator 123 and a visual discovery technology.

[0071] Specifically, the control unit may detect the edge of the oven door located in the operation target area based on pre-stored shape information of the oven door and a shape recognized by the laser beam generated by the laser generator 123 .

[0072] The control unit may control the nozzle 111 to perform a sealing operation of discharging the sealing material by moving along the edge of the oven door located in the operation target area.

[0073] Refer again Figure 2b , the robot 120 may further include a first camera 124 and a second camera 125 .

[0074] The first camera 124 may be provided at, for example, an end of the robot arm 121. The first camera 124 may obtain an image including an area near the end of the robot arm 121.

[0075] The control unit may monitor the progress of the sealing operation with respect to the operation target area based on the image obtained by the first camera 124 .

[0076] The second camera 125 may be provided at, for example, the base 122. The second camera 125 may obtain an image of an area including the operation target area.

[0077] After the sealing operation for the operation target area is completed, the control unit may monitor whether gas leakage occurs in the operation target area based on an image obtained by the second camera 125 .

[0078] When the control unit determines that gas leakage occurs in the operation target area after the sealing operation for the operation target area is completed, the control unit may perform a resealing operation for the operation target area. The control unit may control the robot arm 121 to perform the resealing operation for the operation target area.
