Description

Technical Field

[0002] In the dry quenching coke production process, the water seal tank on the top of the dry quenching coke furnace is a key equipment to ensure production stability and coke quality. Its core function is to effectively seal the coke loading port on the top of the dry quenching furnace after the red coke is loaded into the dry quenching furnace.

[0003] However, the water seal tanks on the top of CDQ ovens widely used on the market are mostly of non-cover or flat cover structure, which may cause problems such as water seal non-circulation and coke powder blockage during production. Coke powder often accumulates on the inner wall of the water seal tank and is difficult to dissipate, resulting in the inner wall of the water seal tank being burned by open flames. As the burning continues to intensify, it is very likely that the inner wall of the water seal tank will be burned through, causing the seal to leak. Summary of the invention

By arranging a sealing cover inside the tank body, the tank body can be separated into a cooling zone and a sealing zone independent of each other, thereby avoiding the risk of interference between the cooling and sealing functions and thus causing coke powder to block the cooling zone; at the same time, by arranging a cooling component to connect the cooling zone, the cooling medium can be caused to circulate continuously, so that the cooling zone is always maintained at a low temperature level, thereby avoiding the risk of high temperature burning through the tank body and causing sealing leakage.

[0033] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0034] A first aspect of the embodiments of the present application provides a water seal groove on a top of a dry quenching coke oven. A second aspect of the embodiments of the present application provides a dry quenching coke oven.

[0035] Among them, the water seal groove on the top of the dry quenching coke oven is used in the dry quenching coke oven.

[0036] Specifically, the dry coke quenching oven top water seal groove is arranged on the top of the coke quenching oven, corresponding to the coke loading port of the dry coke quenching oven. In practical application, when red coke is loaded into the dry coke quenching oven through the coke loading port, the dry coke quenching oven top water seal groove plays the role of sealing the coke quenching oven top.

[0037] See also Figure 1 and Figure 2 As shown, the dry quenching coke oven top water seal tank provided in the embodiment of the present application includes: a tank body 1, a cover 2 is arranged inside the tank body 1, and the cover 2 is used to separate the tank body 1 into a cooling zone 11 and a sealing zone 12; a cooling component, the cooling component is connected to the cooling zone 11, and the cooling component is used to drive the cooling medium to circulate in the cooling zone 11; a sealing component, the sealing component is arranged in the sealing zone 12, and the sealing component is used to cooperate with the furnace cover to seal the top of the dry quenching coke oven.

[0038] In this embodiment, by setting a cover 2 inside the tank body 1, the tank body 1 can be separated into a cooling zone 11 and a sealing zone 12 which are independent of each other, and the cooling and sealing functions can be operated completely independently, so that coke powder cannot enter the cooling zone 11, fundamentally eliminating the risk of coke powder blocking the cooling zone 11, improving the stability and reliability of the operation of the cooling zone 11, and thus ensuring the continuity of the dry coke quenching production. At the same time, by setting the cooling assembly to be connected with the cooling zone 11, the cooling medium can be driven to circulate in the cooling zone 11 to efficiently remove heat, so that the tank body 1 is always maintained in a suitable low-temperature working range, avoiding the tank body 1 from being burned through due to high temperature, ensuring the structural integrity and sealing performance of the tank body 1, and further ensuring the stable operation of the dry coke quenching production.

[0039] The tank body 1 may be an annular groove structure with a certain depth and width to accommodate sufficient cooling medium and provide space required for sealing.

[0040] Specifically, the tank body 1 is arranged near the coke loading port in the dry quenching coke oven, so as to cooperate with the furnace cover of the dry quenching coke oven. In practical applications, when the furnace cover is closed, the furnace cover will interact with the sealing component on the tank body 1 to seal the top of the dry quenching coke oven, prevent the high-temperature gas and dust in the dry quenching coke oven from leaking into the external environment, and ensure that the dry quenching process is carried out in a closed environment.

[0041] The tank body 1 is provided with a cover 2, which may be an annular flat plate structure. In practical applications, inside the tank body 1, the cover 2 is located parallel to the bottom of the tank body 1, and a certain gap is reserved between the cover 2 and the bottom of the tank body 1, so as to separate the space inside the tank body 1 into a sealing area 12 and a cooling area 11.

[0042] Specifically, the cooling zone 11 is between the cover 2 and the bottom of the tank body 1, and the side of the cover 2 facing away from the bottom of the tank body 1 is the sealing zone 12. In practical applications, the edge of the cover 2 fits tightly with the inner wall of the tank body 1 to prevent leakage between the cooling zone 11 and the sealing zone 12. For example, a rubber sealing gasket or a sealing strip can be provided on the edge of the cover 2 to fill the small gap between the cover 2 and the tank body 1 through extrusion deformation to ensure the sealing between the two zones and avoid mutual leakage of the cooling medium and the sealing medium, coke powder, etc. It should be noted that the part of the inner wall of the tank body 1 relative to the cooling zone 11 is closer to the red coke in the dry quenching coke oven than the part of the inner wall of the tank body 1 relative to the sealing zone 12. As a result, it can first bear the high temperature impact of the red coke, thereby effectively reducing the surrounding temperature, avoiding excessive temperature from damaging the tank body 1 and affecting the sealing effect.

[0043] In order to absorb the heat emitted by the red coke, the cooling zone 11 is connected to the cooling component, and the cooling medium is driven by the cooling component to circulate in the cooling zone 11 to quickly transfer the absorbed heat, so that the temperature of the cooling zone 11 is always maintained within an acceptable range.

[0044] Specifically, see Figure 1As shown, the cooling assembly includes a supply pipe 6 and a discharge pipe 7, the supply pipe 6 passes through the cover 2 and is connected to the cooling zone 11, the supply pipe 6 is used to inject a cooling medium into the cooling zone 11, the discharge pipe 7 passes through the outer wall of the tank body 1 and is connected to the cooling zone 11, and the discharge pipe 7 is used to discharge the cooling medium in the cooling zone 11. In practical applications, the cooling medium can be water, thermal oil, or liquid metals such as sodium and potassium. In the embodiment of the present application, the cooling medium is cooling water, and the supply pipe 6 is connected to a cooling water tank or a circulating water system to ensure that a stable low-temperature cooling water continues to flow into the cooling zone 11. During the injection process, the cooling water enters at a constant flow rate, fully contacts the inner wall of the high-temperature cooling zone 11, that is, the part of the inner wall of the tank body 1 relative to the cooling zone 11, and quickly absorbs the heat emitted by the red coke to the cooling zone 11, and then the cooling water whose temperature rises after absorbing the heat is promptly discharged through the discharge pipe 7 to avoid heat accumulation in the cooling zone 11.

[0045] In order to seal the furnace cover and the tank body 1, a sealing component is provided in the sealing area 12 of the tank body 1. The sealing component cooperates with the furnace cover to achieve sealing of the dry quenching coke oven top, prevent high-temperature gas, dust, etc. in the dry quenching coke oven from leaking into the external environment, and ensure that the dry quenching process is carried out in a closed environment.

[0046] Specifically, see Figure 2 As shown, the sealing assembly includes a nozzle 3, and a plurality of nozzles 3 are provided on the upper surface of the cover 2. The plurality of nozzles 3 are used to spray a sealing medium, and the sealing medium can accumulate in the sealing area 12, and cooperate with the furnace cover to seal the furnace top of the dry quenching coke oven. In practical applications, the sealing medium can also be water, heat transfer oil, or liquid metals such as sodium and potassium. In the embodiment of the present application, the sealing medium is also cooling water. When the dry quenching coke oven is performing coke loading and quenching operations, a plurality of nozzles 3 distributed on the upper surface of the cover 2 start to work, and spray cooling water to the sealing area 12 with a uniform and stable pressure. After these cooling waters are sprayed out from the nozzles 3 at a high speed, they quickly spread in the sealing area 12, and finally accumulate in the gap between the furnace cover and the tank body 1. It should be noted that as the cooling water continues to accumulate, a continuous and dense water sealing layer will be formed at the contact portion between the furnace cover and the sealing area 12. This water sealing layer can fully fill the tiny gap between the two, so as to achieve the purpose of sealing the dry quenching coke oven top.

[0047] In some possible implementations disclosed in this application, see Figure 2 As shown, the sealing assembly further includes a drain pipe 4 , which is connected to the sealing area 12 , and is used to discharge the coke powder that enters the sealing area 12 .

[0048] In this embodiment, by disposing a sewage pipe 4 to discharge the coke powder entering the sealing area 12, the sealing area 12 can be kept clean, the integrity and stability of the sealing structure can be ensured, and a good sealing effect can be maintained.

[0049] The drain pipe 4 can be directly connected to the sealing area 12. For example, an interface is provided at the bottom or side of the sealing area 12, and the drain pipe 4 is fixedly connected to the interface to ensure the sealing of the connection and prevent leakage during the discharge of coke powder.

[0050] Specifically, since the coke powder has a certain mass, after entering the sealing area 12, it will settle to the bottom of the sealing area 12 under the action of gravity. In order to improve the discharge efficiency of the coke powder in the sealing area 12, in the embodiment of the present application, the connecting port between the drain pipe 4 and the sealing area 12 is located at a lower position at the bottom of the sealing area 12, so that the coke powder can naturally gather in the direction of the drain pipe 4 under the action of gravity. It should be noted that in the embodiment of the present application, when several nozzles 3 spray cooling water to the sealing area 12, the flow of cooling water can be used to drive the coke powder to be discharged through the drain pipe 4, so as to achieve more effective discharge of the coke powder.

[0051] In some possible implementations disclosed in this application, see Figure 2 As shown, the sealing assembly further includes a guide plate 5 , which is disposed on the upper surface of the cover 2 , and is used to guide coke powder and sewage into the sewage pipe 4 .

[0052] In this embodiment, the guide plate 5 is provided to change the flow direction of coke powder and sewage, so that the coke powder and sewage reach the inlet of the sewage pipe 4 more quickly and directly, reducing the residence time and disordered flow in the sealing area 12, thereby improving the overall sewage discharge efficiency.

[0053] The guide plate 5 may be a plate-shaped structure with a certain curvature and slope.

[0054] Specifically, in actual applications, when coke powder and sewage are generated in the sealing area 12, the initial flow direction of the coke powder and sewage may be chaotic. In the embodiment of the present application, the flow direction of the coke powder and sewage is changed by setting the guide plate 5, so that the coke powder and sewage can flow toward the sewage pipe 4. For example, when the coke powder and sewage spread toward the edge of the sealing area 12, the guide plate 5 will intercept and guide them to the direction connected to the sewage pipe 4, so as to prevent them from being scattered or accumulated in the sealing area 12.

[0055] In some possible implementations disclosed in this application, see Figure 2 As shown, the spraying direction of the nozzle 3 is set at an angle to the radial direction of the cover 2, and the spraying directions of several nozzles 3 are the same.

[0056] In this embodiment, by setting the nozzle 3 to spray in a direction at a certain angle to the radial direction of the cover 2, the sealing medium can be evenly covered on the upper surface of the cover 2 in a ring shape, and compared with vertical spraying, the sealing gap can be filled more completely, thereby improving the reliability of the seal.

[0057] The radial direction of the cover 2 is the direction from the center to the edge of the cover 2. The spraying direction of the nozzle 3 is set at an angle to the radial direction of the cover 2, that is, the nozzle 3 does not spray along the radial direction of the cover 2.

[0058] Specifically, in the embodiment of the present application, thirty-six nozzles 3 are provided. All thirty-six nozzles 3 spray at the same inclination angle and direction. It should be noted that the radial inclination angle of the nozzle 3 relative to the cover 2 can be adjusted according to actual design requirements and working conditions, and can generally be determined according to the size and shape of the sealing area 12, as well as the sealing and cleaning effects to be achieved, and the present application does not limit this. For example, the radial inclination angle of the nozzle 3 relative to the cover 2 can be set between 30° and 60°.

[0059] In some possible implementations disclosed in this application, see Figure 2 As shown, the guide plate 5 extends in an arc shape along the radial direction of the cover 2 , and the extending direction of the guide plate 5 is the same as the spraying direction of the nozzle 3 .

[0060] In this embodiment, the guide plate 5 extends in an arc shape along the radial direction of the cover 2, which can reduce the accumulation of coke powder or splashing of sewage caused by sudden changes in the flow path. At the same time, the extension direction of the guide plate 5 is the same as the injection direction of the nozzle 3, and can work together with the sealing medium flow injected by the nozzle 3, so that the sealing medium pushes the coke powder and sewage to flow more smoothly along the guide plate 5, improves the efficiency and effect of the diversion, and ensures that the coke powder and sewage can flow to the sewage pipe 4 quickly and effectively.

[0061] Among them, the arc-shaped guide plate 5 can cover a larger area and can guide the coke powder and sewage to flow along the arc-shaped path, avoiding the flow dead corners, so that the coke powder and sewage can be guided to the sewage pipe 4 more smoothly.

[0062] The spraying direction of the nozzle 3 determines the initial flow direction of the sealing medium and the coke powder and sewage driven by it. The extension direction of the guide plate 5 is the same as the spraying direction of the nozzle 3, so that the guide plate 5 can guide the flow trend of the sealing medium and impurities. Therefore, after the sealing medium and impurities are sprayed out from the nozzle 3, they can naturally flow along the direction of the guide plate 5, reducing the flow resistance and energy loss.

[0063] In some possible embodiments disclosed in the present application, the cover 2 is arranged at an angle, and the inner edge of the cover 2 is higher than the outer edge of the cover 2 .

[0064] In this embodiment, the cover 2 is tilted and the inner edge of the cover 2 is higher than the outer edge of the cover 2, so that the coke powder and sewage in the sealing area 12 can flow naturally from the inner edge to the outer edge under the action of gravity and enter the sewage pipe 4 more smoothly. At the same time, the cover 2 is tilted and the inner edge of the cover 2 is higher than the outer edge of the cover 2, which can increase the contact area between the cooling zone 11 and the inner wall of the tank body 1, that is, the heat exchange area, so that the heat transfer between the cooling medium in the cooling zone 11 and the inner wall of the tank body 1 is more sufficient, and the heat transferred from the red coke to the tank body 1 is absorbed more efficiently, thereby improving the cooling efficiency.

[0065] When the cover 2 is an annular flat plate structure, the inner edge of the cover 2 is the inner edge of the annular flat plate close to the center of the circle, and the outer edge of the cover 2 is the outer edge of the annular flat plate away from the center of the circle.

[0066] Among them, in the embodiment of the present application, the nozzle 3 is arranged near the inner edge of the cover 2, and the output end of the nozzle 3 faces the outer edge of the cover 2. When the nozzle 3 starts to work and sprays out the sealing medium (such as cooling water), since it is close to the inner edge and sprays toward the outer edge, the sealing medium can be quickly and evenly spread on the surface of the cover 2 with the help of the inclination angle of the cover 2. On the one hand, the flushing effect on the impurities in the sealing area 12 is strengthened, and in coordination with gravity, the coke powder and sewage are prompted to flow to the sewage pipe 4 more efficiently, which greatly improves the sewage discharge efficiency, ensures the cleanliness of the sealing area 12, and then maintains the sealing effect. On the other hand, in the process of a large amount of sealing medium flowing from the inner edge to the outer edge along the inclined surface of the cover 2, the cooling effect is further enhanced on the basis of the increased heat exchange area. When flowing, the sealing medium can not only directly absorb the heat transferred from the inner wall of the tank body 1, but also form a dynamic cooling layer on the surface of the cover 2, accelerate the heat dissipation, effectively suppress the temperature rise of the tank body 1, and ensure the stable operation of the dry quenching coke oven under high temperature conditions.

[0067] In some possible implementations disclosed in this application, see Figure 1 As shown, a bracket 8 is provided on the inner wall of the tank body 1 , and the cover 2 is placed on the bracket 8 and fixed relative to the bracket 8 .

[0068] In this embodiment, the bracket 8 can provide reliable support for the cover 2, ensuring that the cover 2 remains in the correct position during the operation of the dry quenching coke oven and does not sink or shift due to its own weight, thereby ensuring the stability of the entire device structure.

[0069] The bracket 8 is disposed in the cooling zone 11 , and the cover 2 and the bracket 8 can be fixed by bolt connection.

[0070] Specifically, two annular supports 8 are arranged radially opposite to each other on the inner wall of the tank body 1 where the cooling zone 11 is located. When the cover 2 is placed on the two annular supports 8, the weight of the cover 2 is evenly distributed, thus avoiding deformation or damage caused by uneven local force.

[0071] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0072] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
