Description

Technical Field

[0001] This application generally relates to the field of coke oven flue gas treatment technology. More specifically, this application relates to a sealing device for a guide sleeve of a flue gas guide car; further, this application also relates to a flue gas guide car. Background Technology

[0002] In the coking process of coke ovens, the charging operation generates a large amount of raw coal gas containing toxic substances such as benzo[a]pyrene, carbon monoxide, and hydrogen sulfide. To control the escape of this flue gas, a flue gas guide car covers the coke oven flue gas orifice with a guide sleeve system to guide the flue gas into the purification device. However, in actual operation, the relative movement between the guide sleeve of the flue gas guide car and the cover lifting shaft results in flue gas escape. This escaped flue gas contains toxic substances, and long-term exposure may lead to chronic diseases. Tar particles in the coke oven flue gas can penetrate deep into the lungs, causing inflammation or cardiovascular diseases. Furthermore, the escaped acidic gases accelerate the corrosion of metal components, shorten equipment lifespan, and impose a heavy workload on personnel.

[0003] In view of this, there is an urgent need to provide a sealing device for the guide sleeve of the smoke guide car and a smoke guide car solution, so as to achieve the sealing of coal loading flue gas, effectively reduce environmental pollution, and extend the service life of the equipment. Utility Model Content

[0004] In order to at least solve one or more of the technical problems mentioned above, this application proposes a sealing device for the guide sleeve of a smoke guide car and a smoke guide car in several aspects, which can prevent the escape of smoke.

[0005] In a first aspect, this application provides a sealing device for a smoke guide sleeve, comprising:

[0006] A first liquid tank is disposed at the bottom of the smoke guide vehicle's cover, with its opening facing upwards and containing a liquid medium inside; and a sealing groove is disposed at the top of the smoke guide vehicle's guide sleeve, with its opening facing downwards and opposite to the first liquid tank, and the cross-sectional area of ​​the sealing groove's opening is smaller than the cross-sectional area of ​​the first liquid tank's opening; when the cover lifting cylinder drives the cover to rise, the sealing groove is embedded inside the first liquid tank to form a first liquid sealing interface.

[0007] In some embodiments, both the first liquid tank and the sealing groove are cylindrical structures; the opening diameter of the first liquid tank is 300 mm to 400 mm; and the opening diameter of the sealing groove is 100 mm to 300 mm.

[0008] In some embodiments, the height of the first liquid tank is not less than the height of the sealing groove, and the height of the first liquid tank is 350mm to 450mm; the height of the sealing groove is 300mm to 400mm.

[0009] In some embodiments, the first liquid tank has an overflow port on its side wall and an openable and closable drain hole at its bottom for maintaining the liquid level.

[0010] In some embodiments, a second liquid tank is provided on the coke oven flue gas guide seat, and the second liquid tank contains a liquid medium. When the guide sleeve descends to the coke oven flue gas guide seat, the bottom end of the guide sleeve and the second liquid tank form a second liquid sealing interface.

[0011] In a second aspect, this application provides a smoke guide vehicle, which includes the sealing device of the smoke guide vehicle guide sleeve described above.

[0012] In some embodiments, the smoke guide vehicle is provided with two sets of guide sleeves and two sets of opening covers, and the two sets of guide sleeves are interconnected.

[0013] Through the sealing device of the guide sleeve and the guide carriage provided above, this embodiment of the application adds a first liquid groove at the bottom of the cover and sets a sealing groove at the top of the guide sleeve, the two interlocking to form a cross-liquid sealing structure. This liquid sealing structure utilizes the fluidity of the liquid to fill mechanical gaps, achieving complete sealing of the coal charging flue gas. This sealing design not only significantly improves sealing reliability but also simplifies equipment structure and reduces manufacturing and maintenance costs. By blocking the escape of toxic fumes, this solution can effectively reduce environmental pollution, reduce health risks to personnel, and reduce the corrosion of equipment by acidic gases, extending equipment service life, resulting in significant environmental and economic benefits.

[0024] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2As shown, in some embodiments, this application provides a sealing device for the guide sleeve 103 of a smoke guide cart 100, comprising: a first liquid tank 102 disposed at the bottom of the cover 101 of the smoke guide cart 100, the first liquid tank 102 being open upward and containing a liquid medium 106; and a sealing groove 104 disposed at the top of the guide sleeve 103 of the smoke guide cart 100, the sealing groove 104 being open downward and opposite to the first liquid tank 102, and the cross-sectional area of ​​the opening of the sealing groove 104 being smaller than the cross-sectional area of ​​the opening of the first liquid tank 102; when the cover 101 lifting cylinder drives the cover 101 to rise, the sealing groove 104 is embedded inside the first liquid tank 102 to form a first liquid sealing interface.

[0026] This application proposes a sealing device for the guide sleeve 103 of a smoke guide car 100, aiming to solve the problem of flue gas leakage due to inadequate sealing in the prior art, and to achieve complete sealing of coal charging flue gas. The sealing device includes two key parts: a first liquid tank 102 and a sealing groove 104. Specifically, the first liquid tank 102 is installed at the bottom of the cover 101 of the smoke guide car 100, with its opening facing upwards, and is filled with a liquid medium 106 (such as water). The sealing groove 104 is located at the top of the guide sleeve 103 of the smoke guide car 100, with its opening facing downwards, opposite to the first liquid tank 102. In particular, the cross-sectional area of ​​the opening of the sealing groove 104 is designed to be smaller than the cross-sectional area of ​​the opening of the first liquid tank 102; this dimensional difference provides a structural basis for forming an effective sealing interface.

[0027] When the lifting cylinder drives the cover 101 to rise, the sealing groove 104 gradually embeds into the first liquid groove 102. As the cover 101 continues to rise, the relative position between the sealing groove 104 and the first liquid groove 102 continuously changes, forming a complete liquid-sealed interface, i.e., the first liquid-sealed interface. Figure 3 As shown, the sealing interface provided in this application, by utilizing the fluidity of the liquid medium 106, can effectively fill any tiny gaps that may exist between the guide sleeve of the flue gas guide car and the coke oven flue gas guide hole seat. This characteristic allows the sealing interface to adapt to different mechanical deviations and wear conditions, thereby significantly improving the sealing effect and reducing or even eliminating flue gas escape. It is worth noting that... Figure 3 The arrows in the image indicate the direction in which the smoke dissipates.

[0028] The solution provided in this application utilizes the properties of the liquid medium 106 to achieve sealing through simple and effective mechanical movement. Compared with traditional mechanical seals, this sealing method not only improves the reliability of the seal but also reduces the risk of seal failure due to component wear or deformation. Furthermore, the sealing device has a relatively simple structure, is easy to manufacture and maintain, and helps reduce the overall cost of the equipment.

[0029] In some embodiments, both the first liquid tank 102 and the sealing groove 104 are cylindrical structures; the opening diameter of the first liquid tank 102 is 300mm to 400mm; the opening diameter of the sealing groove 104 is 100mm to 300mm. The height of the first liquid tank 102 is not less than the height of the sealing groove 104, and the height of the first liquid tank 102 is 350mm to 450mm; the height of the sealing groove 104 is 300mm to 400mm.

[0030] In the sealing device of the guide sleeve 103 of the smoke guide vehicle 100 of this application, both the first liquid tank 102 and the sealing tank 104 adopt a cylindrical structure. This shape helps to ensure that the liquid medium 106 is evenly distributed in the tank. When the lifting cylinder of the cover 101 drives the cover 101 to rise, the sealing tank 104 is embedded in the first liquid tank 102. The relative movement of the two can form a stable sealing interface, effectively preventing the smoke from escaping.

[0031] The first liquid tank 102 is located at the bottom of the cover 101 of the smoke guide cart 100, with its opening facing upwards. Its opening diameter can be any parameter between 300mm and 400mm, and its height can be any parameter between 350mm and 450mm. The sealing groove 104 is located at the top of the guide sleeve 103 of the smoke guide cart 100, with its opening facing downwards, opposite to the first liquid tank 102. Its opening diameter can be any parameter between 100mm and 300mm, and its height can be any parameter between 300mm and 400mm. In other words, in the solution of this application, not only is the opening diameter of the first liquid tank 102 larger than that of the sealing groove 104, but the height of the first liquid tank 102 is also set to be greater than the height of the sealing groove 104. This allows the sealing groove 104 to more fully contact the first liquid tank 102 and form an effective liquid seal interface, thereby ensuring the stability and durability of the seal.

[0032] In one specific implementation, the opening diameter of the first liquid tank 102 is 350 mm and the height is 400 mm. The opening diameter of the sealing tank 104 is 200 mm and the height is 350 mm.

[0033] In some implementations, the filling height of the liquid medium 106 is set to be no less than 150 mm, which is crucial for achieving effective sealing of the guide sleeve 103 sealing device of the smoke guide vehicle 100. Those skilled in the art will understand that the liquid medium 106 is a key element in forming the sealing interface, and its filling height directly affects the stability and reliability of the sealing effect. When the lifting cylinder of the cover 101 drives the cover 101 to rise, and the sealing groove 104 is inserted into the first liquid tank 102, a sufficient height of liquid medium 106 ensures that the sealing groove 104 is completely immersed in liquid during the insertion process, thereby forming a continuous and effective liquid seal interface. Conversely, if the height of the liquid medium 106 is insufficient, the sealing groove 104 may not be fully wetted, resulting in a discontinuous sealing interface, which in turn allows smoke to easily escape from the gaps, affecting the sealing effect. Therefore, in practical applications, to ensure that the filling height of the liquid medium 106 meets the requirements, a liquid level monitoring device can be installed on the first liquid tank 102 to monitor the liquid level of the liquid medium 106 in real time. When the liquid level is below 150mm, replenish the liquid medium 106 promptly to ensure the sealing device is always in good working condition. This ensures reliable operation of the sealing device under various working conditions and effectively prevents flue gas from escaping.

[0034] In one specific implementation, the first liquid tank 102 has an overflow port on its side wall and an openable and closable drain hole at its bottom to maintain the liquid level.

[0035] During the operation of the flue gas guide car 100, the liquid medium 106 may experience a drop in level due to evaporation or leakage. In this case, replenishing the liquid medium 106 will restore the level to the normal range. If there is too much liquid medium 106, causing the level to be too high, the excess liquid can be discharged through the overflow port to prevent overflow into the first liquid tank 102, avoiding environmental pollution and resource waste, and maintaining a stable liquid level. Furthermore, during coal loading operations, solid impurities in the flue gas, such as coke powder and coal powder, may enter the first liquid tank 102. These impurities accumulate at the bottom of the tank over time, affecting the cleanliness of the liquid and the sealing effect. By providing an openable and closable drain hole at the bottom of the first liquid tank 102, impurities can be periodically discharged, keeping the liquid medium 106 clean and ensuring the normal operation of the sealing device. The openable and closable design of the drain hole also facilitates maintenance and cleaning. During maintenance, the drain hole is closed and some liquid medium 106 is discharged for easy manual or mechanical cleaning. After cleaning, the drain hole is opened, liquid is replenished to the normal level, and the sealing device is restored to operation.

[0036] In one specific implementation, a second liquid tank is provided on the coke oven flue gas guide seat 105, and a liquid medium 106 is provided in the second liquid tank. When the guide sleeve 103 descends to the coke oven flue gas guide seat 105, the bottom end of the guide sleeve 103 forms a second liquid sealing interface with the second liquid tank.

[0037] In the proposed sealing scheme of the guide sleeve 103 of the flue gas guide car 100, a second liquid groove is provided on the coke oven flue gas guide hole seat 105. The second liquid groove is a cylindrical groove and contains liquid medium 106. When the guide sleeve 103 of the flue gas guide car 100 descends to the coke oven flue gas guide hole seat 105, the bottom end of the guide sleeve 103 is inserted into the second liquid groove to form a second liquid sealing interface.

[0038] Those skilled in the art will understand that during coal charging operations, the guide sleeve 103 of the flue gas guide car 100 needs to fit tightly with the coke oven flue gas guide hole seat 105 to prevent flue gas from escaping through the gap between them. This application, by setting a second liquid groove at the coke oven flue gas guide hole seat 105 and utilizing the fluidity of the liquid medium 106 to form a liquid-sealed interface with the bottom end of the guide sleeve 103 of the flue gas guide car 100, can effectively fill the minute gaps caused by machining errors, installation deviations, or long-term use, thereby achieving a reliable sealing effect.

[0039] Furthermore, the formation of the second liquid-sealed interface further enhances the stability and reliability of the entire sealing system. Working together with the first liquid-sealed interface, it creates a double-seal protection, minimizing the possibility of flue gas leakage. This double-seal design not only improves sealing performance but also ensures the long-term stable operation of the flue gas guide vehicle 100 under complex working conditions, helping to reduce equipment maintenance costs and environmental pollution risks.

[0040] In some embodiments, this application provides a smoke guide vehicle 100, which includes the sealing device of the smoke guide vehicle 100 guide sleeve 103 described above.

[0041] This application provides a smoke guide car 100, and the smoke guide car 100 is equipped with the aforementioned smoke guide car 100 guide sleeve 103 sealing device. With its unique structure and function, the device significantly improves the sealing performance and environmental benefits of the smoke guide car 100 in coal loading operations.

[0042] In one specific implementation, the smoke guide vehicle 100 is provided with two sets of guide sleeves 103 and two sets of cover 101, and the two sets of guide sleeves 103 are interconnected.

[0043] In this application, the flue gas guide car 100 is equipped with two sets of guide sleeves 103 and two sets of lifting covers 101. Each set of guide sleeves 103 and lifting covers 101 is equipped with the aforementioned sealing device, that is, each set of guide sleeves 103 has a sealing groove 104 at its top, and each set of lifting covers 101 has a first liquid groove 102 at its bottom. This design of double guide sleeves 103 and double lifting covers 101 allows the flue gas guide car 100 to cooperate with two coke oven flue gas guide seat 105 simultaneously, significantly improving the efficiency of coal charging operations. In addition, the two sets of guide sleeves 103 in this application are interconnected to form an integrated flue gas collection and discharge system. When the flue gas guide car 100 is working, the two sets of guide sleeves 103 are simultaneously inserted into the second liquid groove of the corresponding coke oven flue gas guide seat 105. The flue gas enters the flue gas collection system inside the flue gas guide car 100 through the guide sleeves 103, and is then uniformly introduced into the purification device for treatment.

[0044] The flue gas guide car 100 provided in this application, by setting two sets of interconnected guide sleeves 103, can more efficiently collect and export flue gas, reduce the residence time of flue gas on the furnace top, and reduce the risk of flue gas escape. In addition, this interconnected design helps to balance the air pressure inside the flue gas guide car 100, making the flue gas flow more smoothly and further improving the efficiency of flue gas collection.
