Description
Technical Field
[0001] This utility model relates to the field of gas transportation safety protection technology, and in particular to a dehydration overflow water seal flame arrester in a gas power generation system. Background Technology
[0002] In gas power generation systems, gas, as fuel, must be safely and efficiently transported to the power generation equipment via pipelines. However, if backfire or flame propagation occurs within these pipelines, it can easily lead to an explosion. Therefore, flame arresters are crucial components for ensuring system safety. Traditional flame arresters often use structures such as metal mesh or corrugated plates to mechanically block the flame. However, for gas with high moisture content, they lack effective dehydration and flame quenching mechanisms. Furthermore, single flame arrestor structures are prone to performance degradation due to impurities clogging or liquid accumulation during long-term operation.
[0003] Currently, in the process of flame arresting gas, traditional flame arresters are unable to effectively disperse the gas and quench it with liquid media. When the flame passes through the flame arrestor structure, it is easy to penetrate and cannot reliably prevent backfire. Therefore, we propose a dehydrated overflow water seal flame arrester for gas power generation systems to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and to propose a dehydration overflow water seal flame arrester for a gas power generation system.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dehydration overflow water seal flame arrester in a gas power generation system includes a delivery pipe and a flame arrestor tank fixedly installed on the delivery pipe. The flame arrestor tank is provided with a flame arrestor chamber and a filter chamber, which are connected by a connecting hole. An air inlet communicating with the delivery pipe is opened on the inner wall of the flame arrestor chamber, and an air outlet communicating with the delivery pipe is opened on the inner wall of the filter chamber. A flame arresting mechanism is provided on the inner wall of the flame arrestor chamber.
[0007] The flame arresting mechanism includes an extension pipe fixedly installed on the inner side wall of the flame arresting chamber and communicating with the air inlet. An air blower is fixedly installed at the end of the extension pipe, and flame arresting silicone oil capable of immersing the air blower is placed in the flame arresting chamber.
[0008] Preferably, two connecting end pipes are fixedly installed on the outer wall of the flame arrestor tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-2 The dehydration overflow water seal flame arrester in the gas power generation system includes a delivery pipe 1 and a flame arrestor tank 2 fixedly installed on the delivery pipe 1. The flame arrestor tank 2 is provided with a flame arrestor chamber 3 and a filter chamber 4. The flame arrestor chamber 3 and the filter chamber 4 are connected by a connecting hole 5. An air inlet 6 communicating with the delivery pipe 1 is opened on the inner side wall of the flame arrestor chamber 3, and an air outlet 7 communicating with the delivery pipe 1 is opened on the inner side wall of the filter chamber 4.
[0023] To further explain, the flame arrestor tank 2 is equipped with a flame arrestor chamber 3 and a filter chamber 4, which are connected by a connecting hole 5. The air inlet 6 and the air outlet 7 are respectively connected to the delivery pipe 1. The layout is reasonable, which not only realizes the flame arrestor function, but also prepares for the subsequent filtration process, ensuring the orderly treatment of gas.
[0024] like Figure 1 and Figure 2 As shown, a flame-arresting mechanism is provided on the inner wall of the flame-arresting chamber 3; the flame-arresting mechanism includes an extension pipe 8 fixedly installed on the inner wall of the flame-arresting chamber 3 and connected to the air inlet 6, an air blower 9 is fixedly installed at the end of the extension pipe 8, and flame-arresting silicone oil capable of immersing the air blower 9 is placed inside the flame-arresting chamber 3.
[0025] To further explain, a flame-arresting mechanism is installed in the flame-arresting chamber 3. The gas enters from the inlet 6 through the extension pipe 8 and is dispersed in the flame-arresting silicone oil through the blower 9. The flame propagation in the silicone oil is blocked. The properties of the silicone oil are used to block the flame, which greatly reduces the risk of explosion caused by backfire during gas transportation and ensures the safety of the gas power generation system.
[0026] like Figure 1 As shown, two connecting pipes 10 are fixedly installed on the outer wall of the flame arrestor tank 2. The two connecting pipes 10 are respectively connected to the air inlet 6 and the air outlet 7. The connecting pipes 10 and the end of the conveying pipe 1 are detachably connected by multiple bolt pairs 11.
[0027] To further explain, this design makes installation convenient and quick, and allows for easy disassembly during later maintenance or replacement of the flame arrester, eliminating the need for large-scale modifications to the delivery pipe 1, thus reducing maintenance costs and improving work efficiency.
[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a drainage mechanism is provided on the inner wall of the flame arrestor chamber 3. The drainage mechanism includes an overflow port 12 opened on the inner wall of the flame arrestor chamber 3, and a drainage elbow pipe 13 connected to the overflow port 12 is fixedly installed on the outer wall of the flame arrestor tank 2.
[0029] To further explain, the drainage mechanism, through the overflow port 12 and the drainage elbow pipe 13, can promptly discharge the moisture generated by condensation in the gas and the moisture mixed in the flame-arresting silicone oil, preventing water accumulation from affecting the flame-arresting effect, ensuring the stability of the environment inside the flame-arresting chamber 3, and maintaining the normal operation of the flame arrester.
[0030] like Figure 1 As shown, the overflow port 12 is located below the blower 9.
[0031] To further explain, this design conforms to the movement path of gas and the accumulation pattern of water in the flame arrestor chamber 3.
[0032] like Figure 1 and Figure 3 As shown, a flow limiting mechanism is provided on the inner wall of the flame arresting chamber 3. The flow limiting mechanism includes a fixed plate 14 fixedly installed on the inner wall of the flame arresting chamber 3, and multiple exhaust ports 15 are provided on the top of the fixed plate 14.
[0033] To further explain, the flow-limiting mechanism can prevent excessive airflow from impacting the flame-arresting mechanism, ensuring that the flame and flame-arresting silicone oil can fully interact, stabilizing the flame-arresting effect, and at the same time balancing the airflow distribution in the cavity, making the flame-arresting process more efficient.
[0034] like Figure 3 As shown, the distance between any two adjacent exhaust ports 15 is the same.
[0035] To further explain, this design ensures that the airflow is evenly dispersed when passing through the fixed plate 14, making the gas airflow entering the flame arrestor chamber 3 stable and balanced, avoiding situations where the local airflow is too large or too small, further improving the stability of the flow limiting mechanism in controlling the airflow, and enhancing the consistency of the flame arresting effect.
[0036] like Figure 1 and Figure 2 As shown, a filtration mechanism is provided on the inner wall of the filtration chamber 4. The filtration mechanism includes a limiting block 16 fixedly installed on the inner wall of the filtration chamber 4. An installation port 17 is opened at the top of the limiting block 16, and multiple filter layers 18 are fixedly installed on the inner wall of the installation port 17.
[0037] To further explain, the filtration mechanism can effectively filter impurity particles in the gas, providing a clean gas source for the gas entering the power generation equipment, reducing the wear of the power generation equipment by impurities, extending the service life of the equipment, and improving the stability and reliability of the power generation system.
[0038] The functional principle of this utility model can be explained through the following operation methods:
[0039] Normal operation phase
[0040] Gas flows from the delivery pipe 1 into the flame arrestor tank 2. First, the gas enters the flame arrestor chamber 3 through the air inlet 6, which is connected to the delivery pipe 1. The air inlet 6 is connected to the extension pipe 8, which is fixed to the inner wall of the flame arrestor chamber 3. The gas will flow along the extension pipe 8.
[0041] The gas reaches the blower 9 at the end of the extension pipe 8. The blower 9 disperses the gas so that it enters the flame-retardant silicone oil evenly. In this process, the flame-retardant silicone oil plays a key role in flame retardancy. Even if backfire occurs, the flame will be blocked when passing through the silicone oil and will not be able to spread back to the delivery pipe 1 along the airflow, thus ensuring the safety of gas delivery.
[0042] After being flame-arrested, the gas enters the filter chamber 4 through the connecting hole 5 between the flame-arresting chamber 3 and the filter chamber 4. At this point, the gas reaches the filter mechanism, which consists of multiple filter layers 18 fixed to the mounting port 17 on the top of the limiting block 16 on the inner side wall of the filter chamber 4. These filter layers 18 filter impurities in the gas. The purified gas finally returns to the conveying pipe 1 through the outlet 7 connected to the conveying pipe 1 and continues to flow to the subsequent equipment of the gas power generation system.
[0043] Routine inspection phase
[0044] Users should regularly check the bolt pairs 11 between the two connecting end pipes 10 on the outer wall of the flame arrestor tank 2 and the end of the delivery pipe 1 to see if there is any looseness. If the bolts are found to be loose, tighten them in time with the appropriate tools to ensure that the flame arrestor tank 2 and the delivery pipe 1 are firmly connected to prevent gas leakage.
[0045] Observe the drain elbow 13 to check if any liquid is discharged. Since a drainage mechanism is installed in the flame arrestor chamber 3, condensate in the gas or water mixed in the flame arrestor silicone oil will enter the drain elbow 13 through the overflow port 12 and be discharged. If no liquid is discharged for a long time, it may mean that there is a blockage in the drainage mechanism. Users need to further check the overflow port 12 and other parts, and clean and unclog if necessary.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
