Description

Technical Field

[0001] The utility model relates to the technical field of coke quenching, in particular to a low-moisture coke quenching device. Background Art

[0002] Wet coke quenching uses a quenching car to carry the red coke out of the furnace to the quenching tower and spray it with water. When the quenching car receives coke at a fixed point, the quenching car does not move, resulting in the red coke concentrated in the middle of the coke car, and less red coke at the head and tail ends of the car. At the same time, due to the inclined design of the bottom plate inside the quenching car bucket, some red coke will be affected by gravity and roll to the side of the bucket away from the coke oven. Generally speaking, the thickness of the coke layer is relatively large in the middle of the quenching car and close to the coke platform. The current arrangement of the water spray holes of the spray pipe is: the spray pipe spacing is large at the location of the thick coke layer, and the spray water is sparsely distributed; the spray pipe spacing is small at the location of the thin coke layer, and the spray water is compactly distributed. The density distribution of the spray water column does not match the distribution of coke thickness in the quenching car. In addition, the outlet of the spray water pipe is high from the coke surface. When the quenching water falls on the coke surface, the water has little momentum and cannot reach the coke layer, especially where the coke layer is thick. Therefore, it is urgent to solve it.

[0003] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a low-moisture coke quenching device, which can provide spray water of corresponding strength according to the thickness distribution of the coke layer, and has a simple structure and is easy to implement.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is implemented as follows: a low-moisture coke quenching device comprises: a main water supply pipe, an upper branch pipe and a dense spray assembly; the main water supply pipe is used to provide spray water for coke quenching; the upper branch pipe is connected to the main water supply pipe and is symmetrically distributed along both sides of the main water supply pipe, and an extended spray pipe is provided below the upper branch pipe; the water outlet of the extended spray pipe is located below the coke shield at the upper edge of the quenching car; the dense spray assembly is connected to the main water supply pipe and is used to supplement the spraying of the coke layer in the middle of the coke car and close to the coke platform.

[0006] Preferably, the encrypted spray assembly includes an encrypted spray main pipe, an encrypted spray branch pipe and an encrypted branch pipe; the encrypted spray main pipe is located directly below the main water supply pipe and is connected to the main water supply pipe; the encrypted spray branch pipes are symmetrically distributed along both sides of the encrypted spray main pipe and are connected to the encrypted spray main pipe; both ends of the encrypted branch pipes are connected to adjacent encrypted spray branch pipes, and spray pipes are provided below the encrypted spray main pipe, the encrypted branch pipes and the encrypted spray branch pipes; the water outlet of the spray pipe is located below the coke shield at the upper edge of the coke quenching car.

[0007] Preferably, the spray pipes are evenly spaced along the length direction of the encrypted branch pipes and the encrypted spray branch pipes; the extended spray pipes are evenly spaced along the length direction of the upper branch pipe, and the spacing between adjacent extended spray pipes is greater than the spacing between adjacent spray pipes.

[0008] Preferably, the encrypted spray branch pipe is located directly below the upper branch pipe, the length of the encrypted spray branch pipe is smaller than the length of the upper branch pipe, and no extended spray pipe is provided at the overlapped position of the upper branch pipe and the encrypted spray branch pipe.

[0009] Preferably, the water outlets of the spray pipe and the extended spray pipe are located on the same horizontal plane.

[0010] The beneficial effects of the utility model are embodied in:

[0011] (1) The device provided by the utility model can spray coke layers of different thicknesses at different positions with different intensities according to the distribution of the thickness of the coke layer in the quenching car. This allows the large water flow to quickly and evenly contact all the coke in the quenching car during the quenching process. The coke surface can be quickly cooled under the spray of the large water flow, while the coke interior still retains a relatively high temperature. During the coke drying process, the heat dissipated from the coke interior further evaporates the moisture on the coke surface, thereby obtaining low-moisture coke, which improves the overall quenching effect.

[0012] (2) The device provided by the utility model changes the distance between the water outlet of the spray pipe and the coke surface and raises the height of the coke shield body, so that the impact force of the quenching water when it falls on the coke surface is greater, thereby improving the coke quenching effect.

[0020] Example

[0021] See also Figure 1-3 As shown:

[0022] The utility model provides a low-moisture coke quenching device, comprising: a main water supply pipe 10, an upper branch pipe 20 and a dense spray assembly. The main water supply pipe 10 is used to provide spray water for coke quenching; the upper branch pipe 20 is connected to the main water supply pipe 10 and is symmetrically distributed along both sides of the main water supply pipe 10. An extended spray pipe 70 is provided below the upper branch pipe 20; the water outlet of the extended spray pipe 70 is located below the coke shield on the upper edge of the coke quenching car; the dense spray assembly is connected to the main water supply pipe 10, and is used to supplement the spraying of the coke layer in the middle of the coke car and near the coke platform.

[0023] In actual use, one end of the upper branch pipe 20 is connected to the main water supply pipe 10, and the other end extends to the edges of both sides of the quenching car bucket A, and an extended spray pipe 70 is provided below the upper branch pipe 20, so that the quenching car can be fully covered, so that the entire spray quenching process has no dead angles. In addition, in actual operation, the thickness of the coke layer in the middle of the coke car and the side close to the coke platform is relatively large, and the setting of the dense spray assembly can perform dense spraying here, thereby changing the traditional uniform spraying to targeted spraying, improving the effect of the coke quenching treatment.

[0024] The encrypted spray assembly is mainly composed of an encrypted spray main pipe 30 , an encrypted spray branch pipe 40 and an encrypted branch pipe 50 .

[0025] The encrypted spray main pipe 30 is located directly below the main water supply pipe 10 and is generally configured in an L shape. The encrypted spray main pipe 30 is connected to the main water supply pipe 10 and is fixed by a connecting frame.

[0026] The encrypted spray branch pipes 40 are symmetrically distributed along both sides of the encrypted spray main pipe 30 and are connected with the encrypted spray main pipe 30; the two ends of the encrypted branch pipe 50 are connected with the adjacent encrypted spray branch pipes 40, so that the encrypted spray main pipe 30, the encrypted spray branch pipes 40 and the encrypted branch pipes 50 form a grid-like spray structure above the middle part of the coke car and one side near the coke platform, thereby realizing fixed-point spraying of the coke layer in the middle part of the coke car and one side near the coke platform, increasing the water flow of the spraying here, and improving the coke quenching effect.

[0027] A spray pipe 60 is provided below the encrypted spray main pipe 30, the encrypted branch pipe 50 and the encrypted spray branch pipe 40, and the water outlet of the spray pipe 60 is located below the coke shield at the upper edge of the coke quenching vehicle. In actual use, the length of the spray pipe 60 is less than the length of the extended spray pipe 70, but the length of the spray pipe 60 and the length of the extended spray pipe 70 are both on the same horizontal line, ensuring that the pressure of the water is consistent during spraying.

[0028] The spray pipes 60 are evenly spaced along the length direction of the densified branch pipes 50 and the densified spray branch pipes 40; the extended spray pipes 70 are evenly spaced along the length direction of the upper branch pipe 20, and the spacing between adjacent extended spray pipes 70 is greater than the spacing between adjacent spray pipes 60. Through such a setting, it can match the uneven thickness distribution of the coke layer in the quenching bucket A, so that in actual use, it can provide a matching amount of spray water, which can not only improve the quenching effect, but also save water resources.

[0029] The encrypted spray branch pipe 40 is located directly below the upper branch pipe 20 . The length of the encrypted spray branch pipe 40 is less than that of the upper branch pipe 20 . No extended spray pipe 70 is provided at the overlapped portion of the upper branch pipe 20 and the encrypted spray branch pipe 40 .

[0030] In actual use, when the wet quenching process is implemented in a 6m top-loading coke oven, the dense spray main pipe 30 and the upper branch pipe 20 both adopt the matching dimensions of the conventional low-moisture wet quenching process; and the height of the coke shield body above the quenching bucket A is increased by 300-500mm to match the intensity of the coke layer movement under the large water flow spray. The water outlets of the spray pipe 60 and the extended spray pipe 70 are both located below the lower edge of the coke shield.

[0031] The specific dimensions are: the encrypted sprinkler main pipe 30 is set as a DN350 pipe; the upper branch pipe 20 and the encrypted sprinkler branch pipe 40 are both set as DN150 pipes; the extended sprinkler pipe 70 and the sprinkler pipe 60 are both set as DN80 pipes.

[0032] The number of the dense spray branch pipes 40 and the dense branch pipes 50 should be designed according to the size of the top-loaded coke oven, and the number of the spray pipes 60 below the dense spray main pipe 30 should also be designed according to the size of the top-loaded coke oven, so as to meet the spraying requirements of the corresponding coke layer and improve the coke quenching effect.

[0033] With such an arrangement, during the quenching operation, the main water supply pipe 10 is directly connected to the high-level water tank and the quenching pump, so that water spraying from the high-level water tank and direct water spraying from the quenching pump can be carried out simultaneously. The three stages of low pressure, medium pressure and high pressure can be eliminated for quenching, and the maximum water flow is always used for spraying, which can ensure the quenching effect of the entire device.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
