Description

Technical Field

[0001] This utility model relates to the technical field of thermal power plant projects, and in particular to a gas gun device for a thermal power plant oil-to-gas conversion project. Background Technology

[0002] Thermal power plants are power plants that convert chemical energy into thermal energy by burning fossil fuels such as coal, natural gas, oil, or biomass fuels, and then convert the thermal energy into electrical energy through a thermodynamic cycle. As one of the world's major sources of electricity, thermal power plants occupy an important position in the energy structure due to their mature technology, stable power supply, and strong adaptability to fuels. In the oil-to-gas conversion project of thermal power plant equipment, air gun equipment needs to be used in conjunction with it.

[0003] The gas gun equipment in the oil-to-gas conversion project of thermal power plants is a basic tool of the gas system. Its core value lies in solving key problems such as pipeline purging, leak detection, and burner cleaning through airflow control and safety design. However, gas pipelines have various specifications, and the existing gas gun barrels have a fixed length, which cannot reach long pipelines or narrow spaces well, resulting in purging blind spots and reducing the ease of use of the gas gun equipment. The current solution is to use a multi-section telescopic barrel to achieve the purpose of length adjustment and adapt to long pipelines. A damped universal joint with a lockable angle is added to the front end of the barrel to flexibly turn in narrow spaces and eliminate purging blind spots. However, the nozzle is still a one-piece design, which requires replacement of the whole unit after wear. At the same time, the purging pressure drops due to nozzle wear but it is still used, which affects continuous operation. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a gas gun device for oil-to-gas conversion projects in thermal power plants. It aims to improve the existing technology where the nozzle is an integrated design, which requires the entire unit to be replaced after wear. At the same time, the nozzle wear causes a drop in purging pressure, which still affects continuous operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gas gun device for a thermal power plant oil-to-gas conversion project, including a gas gun device, an outer shell fixedly connected to the outer wall of the gas gun device, a replacement mechanism provided on the left side of the outer shell, the replacement mechanism being used to facilitate replacement work and increase the service life of the equipment, and a reinforcing mechanism provided on the inner wall of the outer shell. The replacement mechanism includes a fixing ring, the right side of which is fixedly connected to the left side of the housing. Multiple rotating plates are rotatably connected to the outer wall of the fixing ring. Bolts are threaded onto the outer walls of the multiple rotating plates. A replacement nozzle is threaded onto the end of each bolt. Multiple locking grooves are provided on the outer wall of the replacement nozzle. The left side of the rotating plate engages with the locking grooves. A limit assembly is provided at the bottom of the replacement nozzle.

[0006] As a further description of the above technical solution: The reinforcing mechanism includes a reinforcing layer, the outer wall of which is fixedly connected to the inner wall of the outer shell, and a plurality of pressure-resistant steel plates are fixedly connected to the inner wall of the reinforcing layer. A plurality of holes are opened on one side of the pressure-resistant steel plates, and pressure-resistant rings are fixedly connected between adjacent pressure-resistant steel plates. A polytetrafluoroethylene coating is fixedly connected to the inner wall of the reinforcing layer.

[0007] As a further description of the above technical solution: The limiting component includes a limiting slider, the top wall of which is fixedly connected to the bottom wall of the replacement nozzle, and a guide shell is fixedly connected to the bottom of the housing. A limiting groove is formed on the left side of the top wall of the guide shell, and the bottom of the limiting slider is slidably connected to the limiting groove.

[0008] As a further description of the above technical solution: The outer walls of all of the aforementioned pressure-resistant steel plates are designed to be smooth and are arranged in an equidistant ring.

[0009] As a further description of the above technical solution: The replacement mechanism also includes multiple rubber rings, the inner walls of which are fixedly connected to the middle of the outer wall of the bolt.

[0010] As a further description of the above technical solution: A sealing ring is fixedly connected to the inner wall of the fixing ring, and the outer dimensions of the sealing ring match the inner right side dimensions of the replacement nozzle.

[0011] As a further description of the above technical solution: A rubber sleeve is fixedly connected to the bottom right side of the air gun device, and a base is fixedly connected to the bottom of the rubber sleeve.

[0012] As a further description of the above technical solution: The air gun device has multiple arc-shaped grooves on its left bottom, and these arc-shaped grooves are all equally spaced.

[0013] This utility model has the following beneficial effects: In this invention, the rotation of the bolts releases the lock between the rotating plate and the replacement nozzle. Then, the rotation of the rotating plate separates the plate from the replacement nozzle. By pulling the replacement nozzle, it can be separated from the left side of the housing, achieving convenient disassembly and assembly of the replacement nozzle. This avoids the need for complete replacement after wear, which would affect continuous operation and thus improves the service life of the device.

[0014] In this invention, the reinforcement layer effectively improves the strength of the outer shell. At the same time, the connection of multiple pressure-resistant steel plates can evenly offset the external pressure, thereby protecting the interior of the air gun device. Furthermore, the polytetrafluoroethylene coating effectively reduces the corrosion rate and increases the service life of the equipment. Attached Figure Description

[0019] Reference Figure 1 , Figure 3 and Figure 5The reinforcing mechanism 4 includes a reinforcing layer 401. The outer wall of the reinforcing layer 401 is fixedly connected to the inner wall of the outer shell 3, so that the reinforcing layer 401 can improve the internal strength of the outer shell 3. Multiple pressure-resistant steel plates 402 are fixedly connected to the inner wall of the reinforcing layer 401. The connection of multiple pressure-resistant steel plates 402 can improve the resistance to external pressure, thereby improving the protective effect of the air gun equipment. Multiple holes 403 are opened on one side of the pressure-resistant steel plate 402. The multiple holes 403 can increase the toughness of the pressure-resistant steel plate 402. Pressure-resistant rings 404 are fixedly connected between adjacent multiple pressure-resistant steel plates 402. A polytetrafluoroethylene coating 405 is fixedly connected to the inner wall of the reinforcing layer 401. The polytetrafluoroethylene coating 405 improves the rust resistance of the inner wall of the outer shell 3. Specifically, the outer wall of the reinforcing layer 401 is fixedly connected to the inner wall of the outer shell 3, thereby improving the internal strength of the outer shell 3. At the same time, the multiple pressure-resistant steel plates 402 fixed to its inner wall improve resistance to external pressure, thus enhancing the protective effect on the air gun equipment. The multiple holes 403 opened on one side of the pressure-resistant steel plate 402 increase its toughness. The pressure-resistant rings 404 fixed between adjacent plates further enhance the pressure resistance. The polytetrafluoroethylene coating 405 fixed to the inner wall of the reinforcing layer 401 improves the rust resistance of the inner wall of the outer shell 3, thus further improving the service life of the outer shell 3.

[0020] Reference Figure 1 , Figure 4 and Figure 5 The limiting component 207 includes a limiting slider 2071, the top wall of which is fixedly connected to the bottom wall of the replacement nozzle 205. A guide shell 2072 is fixedly connected to the bottom of the outer shell 3. A limiting groove 2073 is formed on the left side of the top wall of the guide shell 2072.

The outer wall of the pressure-resistant steel plate 402 is designed to be smooth, which improves the pressure resistance and dispersion effect. The connection of the rubber ring 204 reduces the rotational damage of the bolt 203 to the rotating plate 202.

[0021] Reference Figure 1 , Figure 2 and Figure 3A sealing ring 208 is fixedly connected to the inner wall of the fixing ring 201, and the outer dimensions of the sealing ring 208 match the inner right side dimensions of the replacement nozzle 205; a rubber sleeve 5 is fixedly connected to the bottom right side of the air gun device 1, and a base support 6 is fixedly connected to the bottom of the rubber sleeve 5; a plurality of arc-shaped grooves 7 are provided on the bottom left side of the air gun device 1, and the plurality of arc-shaped grooves 7 are all equally spaced.

[0022] Working principle: When replacement begins, rotating the bolt 203 unlocks the rotating plate 202, which is threaded at its end, from the replacement nozzle 205. Then, rotating the plate 202 is flipped to separate it from the locking groove 206 on one side of the replacement nozzle 205, thus unlocking the replacement nozzle 205. Pulling the replacement nozzle 205 then separates it from the left side of the outer casing 3. At the same time, the limiting slider 2071 slides inside the limiting groove 2073, achieving quick and convenient disassembly and assembly. This facilitates the easy disassembly and assembly of the replacement nozzle 205, avoiding the need for complete replacement after wear, which would affect continuous operation. Conversely, installation is completed. Furthermore, the outer wall of the reinforcing layer 401 is fixedly connected to the inner wall of the outer shell 3, which can improve the internal strength of the outer shell 3. At the same time, the multiple pressure-resistant steel plates 402 fixed to its inner wall can improve the resistance to external pressure. The multiple holes 403 opened on one side of the pressure-resistant steel plate 402 can increase its toughness and further improve the pressure resistance. The pressure-resistant rings 404 fixed between adjacent ones help to disperse the pressure, evenly offset the external pressure, protect the inside of the air gun device 1, and improve the protection effect. The polytetrafluoroethylene coating 405 fixed to the inner wall of the reinforcing layer 401 improves the rust resistance of the inner wall of the outer shell 3, reduces the rust rate, and increases the service life of the equipment.
