Description

Technical Field

[0001] This application relates to the field of gas drainers, and in particular to a replaceable water-sealed gas drainer. Background Technology

[0002] Gas drainers, as crucial auxiliary equipment in the gas transmission systems of steel enterprises, play a vital role in the real-time removal of condensate from gas pipelines. In key production stages such as blast furnaces, ironmaking, steelmaking, and rolling mills, gas drainers effectively prevent pipeline corrosion, blockages, and pressure fluctuations caused by condensate accumulation through continuous and stable drainage, ensuring the safe and efficient operation of the gas transmission system. Their design principle is based on the water seal principle, maintaining a certain height of water column to form a sealing barrier and prevent gas leakage, serving as a crucial line of defense for the safe use of gas.

[0003] However, in practical applications, gas drainers face severe corrosion challenges. Because gas often contains corrosive components such as sulfides and chlorides, these substances dissolve in water during condensation, forming highly corrosive condensate. Over time, this condensate severely corrodes the water seal pipe of the gas drainer, causing the pipe wall to thin, perforate, or even break. Traditional gas drainers require complete replacement due to water seal pipe corrosion, which is time-consuming, labor-intensive, and increases operating costs for businesses; therefore, improvements are needed. Utility Model Content

[0004] To address the issue of needing to replace the entire water seal pipe due to corrosion, this application provides a replaceable water seal gas drainer.

[0005] The replaceable water-sealed gas drainer provided in this application adopts the following technical solution:

[0006] A replaceable water-sealed gas drainer includes an outer casing with an open top and a cover plate for covering. The outer casing contains several compartments. One compartment contains a main water seal pipe for communication with a gas pipeline, the lower end of which extends below the liquid level at the bottom of the compartment. The remaining compartments each contain a secondary water seal pipe, the vertical end of which extends below the water level in the corresponding compartment, and the elbow end of which extends into an adjacent compartment. The elbow end of the secondary water seal pipe is detachably mounted on the side wall of the compartment.

[0007] Over time, condensate water severely corrodes the water seal pipe of the gas drainer, causing the pipe wall to thin, perforate, or even break. Traditional gas drainers require complete replacement due to water seal pipe corrosion, which is time-consuming, labor-intensive, and increases the company's operating costs. The above-mentioned technical solution includes an outer shell with a cover plate covering the top. Several compartments are formed inside the outer shell, with the main water seal pipe connected to one of the compartments, and several secondary water seal pipes installed sequentially in the corresponding compartments.

[0008] When the water seal pipe corrodes after prolonged use, disconnect the main water seal pipe from the gas pipeline to prevent gas from entering the drainer. Empty the residual gas and condensate in the faulty compartment, open the cover, and use tools to disassemble the secondary water seal pipe. Pull the corroded secondary water seal pipe out from the side wall of the compartment, taking care to avoid damaging the sealing surface. Install a new secondary water seal pipe, inserting the vertical end of the new secondary water seal pipe below the liquid level in the target compartment. Align the elbow end with the side wall of the adjacent compartment through the flange, seal and fix it, and then inject clean water into the compartment to the design liquid level. Finally, restore the connection between the gas pipeline and the main water seal pipe.

[0009] By incorporating cover plates, main water seal pipes, and secondary water seal pipes, and employing a modular design, the problem of traditional equipment requiring complete replacement due to water seal pipe corrosion is solved. This not only significantly reduces maintenance costs and time but also substantially improves the reliability and service life of the gas drainer, providing strong support for the safe and efficient operation of gas transmission systems in steel enterprises.

[0010] Optionally, the outer casing is provided with a plurality of sewage pipes, which are sequentially connected to each compartment, and each sewage pipe is provided with a sewage valve.

[0011] By adopting the above technical solution, several sewage pipes are connected to each compartment of the outer shell, and sewage valves are installed on the sewage pipes. Through the setting of sewage pipes and sewage valves, and through the synergistic effect of the sewage pipes and sewage valves, operators can flexibly control the sewage discharge process of each compartment, quickly discharge the impurities and sewage deposited in the compartment, effectively avoid equipment corrosion and performance degradation caused by long-term accumulation of dirt, and significantly extend the service life of the equipment.

[0012] Optionally, the outer shell is provided with a drainage tube, one end of which is connected to one of the compartments, and the other end of which extends to the outside of the outer shell.

[0013] By adopting the above technical solution, the drain pipe is installed on the outer casing. The drain pipe significantly enhances the emergency drainage capacity and operational flexibility of the equipment. When the liquid level in the chamber rises abnormally or needs to be emptied urgently, the liquid can be quickly drained through the drain pipe, avoiding the risk of chamber overload or liquid overflow, and improving the safety performance of the gas drainer.

[0014] Optionally, a drainage interface pipe is provided between the outer shell and the drainage pipe, one end of the drainage interface pipe is connected to one of the compartments, and the other end of the drainage interface pipe is connected to the inside of the drainage pipe.

[0015] By adopting the above technical solution, the drain interface pipe is installed between the outer shell and the drain pipe. With the setting of the drain interface pipe, the replaceable water seal gas drainer adds a drain interface pipe between the outer shell and the drain pipe. Its two ends are precisely connected to the interior of a specific compartment and the drain pipe, respectively, to build an independent and efficient liquid transmission channel. This design significantly enhances the equipment's ability to respond to abnormal compartment liquid levels or emergency drainage, and effectively reduces safety risks.

[0016] Optionally, a flange for disassembly and assembly is provided between any of the secondary water seal pipes and the corresponding compartment sidewall, and the flange is provided with fixing bolts for fixing.

[0017] By adopting the above technical solution, the secondary water seal pipe is installed on the side wall of the compartment using flanges and fixing bolts. With the flanges and fixing bolts, the flanges serve as the connection medium, and the fixing bolts help to achieve a stable installation, improving the ease of disassembly and assembly and maintenance efficiency of the secondary water seal pipe. When the secondary water seal pipe needs to be replaced due to corrosion or failure, the flanges can be easily separated by simply removing the fixing bolts, and the old pipe can be quickly removed and the new pipe installed without damaging the compartment structure or affecting other components.

[0018] Optionally, the top of the outer casing is provided with an annular flange for mounting a cover plate, the cover plate abutting against the annular flange of the outer casing.

[0019] By adopting the above technical solution, the circumferential flange is integrally formed on the top of the outer shell, and the cover plate abuts against the circumferential flange of the outer shell. Through the setting of the circumferential flange, the circumferential flange serves as the mounting base for the cover plate. The cover plate precisely abuts against the circumferential flange to form a stable seal, which not only enhances the structural strength of the top of the outer shell, but also provides reliable support and positioning for the cover plate, ensuring the flatness and fit of the sealing surface, and effectively preventing gas leakage and external environmental pollution.

[0020] Optionally, the cover plate is provided with a plurality of fastening bolts for fixing to the circumferential flange of the outer casing, and the plurality of fastening bolts are arranged in a circumferential array on the cover plate.

[0021] By adopting the above technical solution, the cover plate is installed on the outer ring flange of the outer shell by fastening bolts; the setting of fastening bolts ensures that the clamping force between the cover plate and the ring flange is uniform and consistent, effectively eliminating sealing gaps and significantly reducing the risk of gas leakage.

[0022] Optionally, a lower gate valve for isolating gas is provided above the main water seal pipe.

[0023] By adopting the above technical solution, the lower gate valve is installed above the main water seal pipe. As a key component for gas isolation, the lower gate valve can quickly cut off the connection between the main water seal pipe and the gas pipeline when needed, effectively preventing gas from leaking into the drainer or the external environment, and ensuring the safety of operators and equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up cover plates, main water seal pipes and secondary water seal pipes, the modular design solves the problem of traditional equipment requiring complete replacement due to corrosion of water seal pipes. This not only significantly reduces maintenance costs and time, but also significantly improves the reliability and service life of the gas drainer, providing a strong guarantee for the safe and efficient operation of the gas transmission system in steel enterprises.

[0026] 2. Through the coordinated action of the drain pipe and drain valve, operators can flexibly control the drain process of each compartment, quickly discharge the impurities and sewage deposited in the compartment, effectively avoid equipment corrosion and performance degradation caused by long-term accumulation of dirt, and significantly extend the service life of the equipment.

[0027] 3. By setting the lower gate valve, as a key component for gas isolation, the lower gate valve can quickly cut off the connection between the main water seal pipe and the gas pipeline when needed, effectively preventing gas from leaking into the drainer or the external environment, and ensuring the safety of operators and equipment.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a replaceable water-sealed gas drainer. (Refer to...) Figure 1 and Figure 2 The replaceable water-sealed gas drainer includes an outer shell 1. In this embodiment, the outer shell 1 is a cylindrical structure, and several chambers 3 are formed inside the outer shell 1. The top of the outer shell 1 is open.

[0035] Reference Figure 1 and Figure 2 A cover plate 2 is installed on the top of the outer shell 1. An annular flange 12 is integrally formed on the top of the outer shell 1. The cover plate 2 abuts against the annular flange 12 of the outer shell 1. The annular flange 12 serves as the mounting base for the cover plate 2. The cover plate 2 precisely abuts against the annular flange 12 to form a stable seal. This not only enhances the structural strength of the top of the outer shell 1, but also provides reliable support and positioning for the cover plate 2, ensuring a flat and close fit of the sealing surface and effectively preventing gas leakage and external environmental pollution.

[0036] Reference Figure 1 and Figure 2 A number of fastening bolts 13 are installed on the cover plate 2, and the fastening bolts 13 are arranged in a circumferential array on the cover plate 2; this ensures that the clamping force between the cover plate 2 and the ring flange 12 is uniform and consistent, effectively eliminating the sealing gap and greatly reducing the risk of gas leakage.

[0037] Reference Figure 2 In this embodiment, a main water seal pipe 4 is installed in one of the compartments 3. The upper end of the main water seal pipe 4 is connected to the gas pipeline, and the lower end of the main water seal pipe 4 extends to below the liquid level at the bottom of the compartment 3. At the same time, a lower gate valve 14 is installed above the main water seal pipe 4. The lower gate valve 14 can be installed on the main water seal pipe 4 or the gas pipeline. As a key component for gas isolation, the lower gate valve 14 can quickly cut off the connection between the main water seal pipe 4 and the gas pipeline when needed, effectively preventing gas from leaking into the drainer or the external environment, and ensuring the safety of operators and equipment.

[0038] Reference Figure 2 and Figure 3 The remaining compartments 3 are each equipped with a secondary water seal pipe 5. The vertical end of the secondary water seal pipe 5 extends below the water level in the corresponding compartment 3, and the elbow end of the secondary water seal pipe 5 extends into the adjacent compartment 3. In this embodiment, multiple secondary water seal pipes 5 are connected sequentially in the adjacent compartments 3.

[0039] Reference Figure 2 and Figure 4The elbow end of the secondary water seal pipe 5 is detachably mounted on the side wall of the chamber 3. A flange 10 is installed between any one of the secondary water seal pipes 5 and the corresponding side wall of the chamber 3, and a fixing bolt 11 is installed on the flange 10. The flange 10 serves as a connection medium, and the fixing bolt 11 is used to achieve a stable installation, which improves the ease of disassembly and assembly and maintenance efficiency of the secondary water seal pipe 5. When the secondary water seal pipe 5 needs to be replaced due to corrosion or failure, the flange 10 can be easily separated by removing the fixing bolt 11, and the old pipe can be quickly removed and the new pipe installed without damaging the structure of the chamber 3 or affecting other components.

[0040] Reference Figure 2 and Figure 3 The outer casing 1 is equipped with several drain pipes 6, which are sequentially connected to each compartment 3. Each drain pipe 6 is equipped with a drain valve 7. Through the coordinated action of the drain pipes 6 and the drain valves 7, the operator can flexibly control the draining process of each compartment 3, quickly discharge the impurities and sewage deposited in the compartment 3, effectively avoid equipment corrosion and performance degradation caused by long-term accumulation of dirt, and significantly extend the service life of the equipment.

[0041] Reference Figure 2 The top of the outer casing 1 is connected to a drain port pipe 9, which is connected to one of the compartments 3 of the outer casing 1. The end of the drain port pipe 9 away from the outer casing 1 is connected to a drain pipe 8, which extends outward from the outer casing 1. The drain pipe 8 significantly enhances the emergency drainage capacity and operational flexibility of the equipment. When the liquid level in the compartment 3 rises abnormally or needs to be emptied urgently, the liquid can be quickly drained through the drain pipe 8, avoiding the risk of overload or liquid overflow in the compartment 3 and improving the safety performance of the gas drainer.

[0042] The implementation principle of a replaceable water-sealed gas drainer in this application embodiment is as follows: When the water seal pipe corrodes after long-term use, close the lower gate valve 14 to cut off the connection between the main water seal pipe 4 and the gas pipeline, prevent gas from entering the drainer, drain the residual gas and condensate in the faulty compartment 3, open the cover plate 2, loosen the fixing bolts 11, use tools to remove the fixing bolts 11 connecting the elbow end of the secondary water seal pipe 5 to the side wall of the compartment 3, pull out the old pipe, pull out the corroded secondary water seal pipe 5 from the side wall of the compartment 3, taking care to avoid damaging the sealing surface, install the new secondary water seal pipe 5, insert the vertical end of the new secondary water seal pipe 5 below the liquid level in the target compartment 3, align the elbow end with the side wall of the adjacent compartment 3 through the flange, seal and fix it, then inject clean water into the compartment 3 to the design liquid level, open the lower gate valve 14, and finally restore the connection between the gas pipeline and the main water seal pipe 4;

[0043] By incorporating cover plate 2, main water seal pipe 4, and secondary water seal pipe 5, the modular design solves the problem of traditional equipment requiring complete replacement due to water seal pipe corrosion. This not only significantly reduces maintenance costs and time but also substantially improves the reliability and service life of the gas drainer, providing a strong guarantee for the safe and efficient operation of the gas transmission system in steel enterprises.
