Description

Technical Field

[0001] This utility model relates to the field of ignition technology, and in particular to a stable ignition ignition device for combustible gas in oil exploration. Background Technology

[0002] During oil exploration and development, large amounts of toxic and harmful combustible gases are released from oil wells. Once these gases are released into the air, they can poison people and other living organisms in the space. When the concentration reaches a certain level, they can cause a large explosion when exposed to a spark. If the amount of gas used in a gas storage facility is less than the amount of gas entering the facility, the overall pressure of the storage tank will continuously increase. When it reaches a certain level, liquefied natural gas must be released. A large amount of combustible gas filling the air will cause an explosion. Therefore, combustible gases released into the air need to be ignited.

[0003] Traditional ignition devices have a fixed ignition hood angle, which cannot adapt to the changing airflow direction and speed, causing the flame to be easily blown out or detached from the ignition hood. To ensure ignition success rate, continuous high-energy discharge or auxiliary fuel support is often required, resulting in energy waste and additional emissions. The electrode spacing is fixed and cannot be automatically adjusted according to environmental parameters such as gas concentration, humidity, and flow rate, resulting in a low ignition success rate. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the instability of traditional flames leads to the need for higher energy to maintain ignition, thereby increasing energy consumption and pollution; while the design of the fixed structure limits the adaptability of the device to different working conditions, further aggravating the problem of flame instability and energy waste.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a stable ignition igniter for combustible gas in oil exploration, comprising a pipeline, a flame-spraying component connected along the pipeline, an adjusting elbow connected to the flame-spraying component and the pipeline respectively, an arc-initiating cover connected to the end of the flame-spraying component away from the adjusting elbow, and a reaction rod corresponding to the flame-spraying component inside the pipeline.

[0006] The beneficial effects of this utility model are as follows: the use of an adjustable-angle corrugated pipe structure and an arc-ignition shroud counterweight design can respond to changes in airflow direction and speed in real time, automatically adjust the injection angle and flame center of gravity, effectively prevent the flame from being blown out or detached from the ignition shroud, reduce dependence on high-energy discharge or auxiliary fuel, thereby reducing energy waste and pollutant emissions. The gas recovery system composed of the circulation box and the diversion filter box can filter and reuse unburned gas. Combined with the battery module and low-power suction pump (such as a diaphragm micro pump), energy recycling is achieved, further reducing energy consumption and operating costs.

[0007] Furthermore, from bottom to top, the pipeline is fitted with several sets of protective sleeves, anti-slip blocks installed on the side wall of the pipeline, a battery block integrated at the bottom of the pipeline, and a detachable bottom cover fastened to the outside. A charging module corresponding to the battery block is provided outside the pipeline.

[0008] Furthermore, several sets of bellows are sequentially connected to the middle of the adjusting elbow, and a high-temperature resistant sleeve is provided between two sets of bellows. The bellows are used for bending angle adjustment, and both ends of the bellows are provided with sleeved sealing joints. One set of sealing joints faces the flame-spraying component, and several sets of ceramic support plates are embedded circumferentially along the sealing joint. A spiral line is linearly opened on the side wall of the sealing joint, and a pressure sensor is mounted on the ceramic support plate. There is an air outlet between the ceramic support plate and the spiral line.

[0009] Furthermore, a flow-guiding filter box and a circulation box are respectively installed around the sealing joint. A circulating air pipe connects the flow-guiding filter box and the circulation box. The air pipe is connected to the air outlet. A guide pipe is installed at the outer end of the flow-guiding filter box. A pressure gauge is inserted into the side wall of the guide pipe. A filter element is installed inside the circulation box. A pressure module is installed at the side end of the circulation box. An air exchange groove is opened on the outer wall of the pressure module. The pressure module includes a battery module and an air pump that are electrically connected to each other.

[0010] Furthermore, the flame-throwing assembly includes a nozzle tube that connects to the adjusting elbow, a rotating sleeve and a rotating ring fitted on the nozzle tube, positive and negative electrode modules embedded inside the nozzle tube, and a flow control module coaxially arranged with the rotating ring. A sealing ring is fitted around the rotating ring, and a retaining sleeve is integrally formed with the rotating sleeve. A retaining sleeve has a groove on its inner side that connects with the arc-initiating cover.

[0011] Furthermore, connecting rods are installed at the outer ends of both the rotating sleeve and the rotating ring, and a handle is connected between the two sets of connecting rods.

[0012] Furthermore, the flow control module includes a fixed plate that is fixedly connected to the nozzle tube, a sealing partition plate that is coaxially connected to the fixed plate, and several sets of airflow holes distributed on the sealing partition plate. A first connecting sleeve and a second connecting sleeve are installed at the center of the sealing partition plate, and a rotating rod is inserted into the first connecting sleeve and the second connecting sleeve. One end of the rotating rod is fixedly connected to the rotating ring, and a rotary joint is provided between the other end of the rotating ring and the fixed plate. Several sets of sealing blades are fixedly connected to the periphery of the first connecting sleeve and the second connecting sleeve in a circumferential manner.

[0013] Furthermore, several sets of counterweights are fixedly connected to the outer end of the arc-starting cover in a circumferential manner, and a flame-spraying plate is integrated at the end of the arc-starting cover. Several sets of flame holes are distributed on the flame-spraying plate, and a high-temperature resistant ring is provided between the flame-spraying plate and the arc-starting cover.

[0014] The advantages of adopting the above-mentioned further solutions are as follows: By integrating pressure sensors (such as Honeywell MLH series) and flow control modules, the system can monitor parameters such as gas concentration, flow rate, and humidity in real time. The modular design (such as disassembling the bottom cover and installing the arc-starting cover with a clamp) facilitates quick replacement of vulnerable parts (such as filter elements and ceramic support plates). The combination design of the high-temperature resistant sleeve and sealing joint enhances the system's durability in high-temperature and high-pressure environments, making it suitable for harsh working conditions such as oil exploration. The pressure gauge and pressure sensor provide real-time feedback on the internal status of the system, and users can manually fine-tune it via the handle or remotely monitor it via an external controller, effectively preventing the risk of backfire or gas leakage and improving operational safety.

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] In the description of this application, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0019] Example 1; as Figures 1-5 As shown, it includes a pipeline 1, a flame-throwing assembly 3 connected along the pipeline 1, an adjusting elbow 2 connected to the flame-throwing assembly 3 and the pipeline 1 respectively, an arc-starting cover 4 connected to the end of the flame-throwing assembly 3 away from the adjusting elbow 2, and a reaction rod 5 corresponding to the flame-throwing assembly 3 inside the pipeline 1. The pipeline 1 is fitted with several sets of protective sleeves 101, anti-slip blocks 102 installed on the side wall of the pipeline 1, battery blocks integrated at the bottom of the pipeline 1, and detachable bottom covers 103 fastened to the outside from bottom to top. The pipeline 1 is provided with a charging module 104 corresponding to the battery blocks. Several sets of bellows 201 are sequentially connected to the middle of the adjusting elbow 2. A high-temperature resistant sleeve 202 is provided between two sets of bellows 201. The bellows 201 is used for bending angle adjustment. Both ends of the bellows 201 are provided with a sleeved sealing joint 203. One set of sealing joints 203 faces the flame-spraying component 3. Several sets of ceramic support plates 214 are embedded circumferentially along the sealing joint 203. A spiral line 211 is linearly opened on the side wall of the sealing joint 203. A pressure sensor 212 is mounted on the ceramic support plate 214. An air outlet 213 is connected between the ceramic support plate 214 and the spiral line 211.

[0020] During operation, combustible gas enters from pipeline 1 and is delivered to the flame-spraying assembly 3 via adjusting elbow 2. The bellows structure 201 allows for manual or electric adjustment of the bending angle to adapt to changes in external airflow. As the gas flows through the sealing joint 203, the pressure sensor 212 (recommended model Honeywell MLH050PGL06A) monitors the gas pressure data in real time. After the gas flow rate is stabilized by the spiral structure 211, it is ejected from the outlet 213. The positive and negative electrode modules 303 in the flame-spraying assembly 3 generate an electric arc to ignite the gas. The arc-igniting cover 4 maintains the stability of the flame center of gravity through the design of the counterweight block 401, preventing the flame from shifting or going out in strong winds. The reaction rod 5 (coated with platinum and rhodium catalysts) promotes the complete combustion of combustible gas at low temperature and improves combustion efficiency.

[0021] Example 2: Please refer to Figure 1 - Figure 6 Based on Embodiment 1, a flow-guiding filter box 204 and a circulation box 208 are respectively installed around the sealing joint 203. A circulating air pipe 207 is connected between the flow-guiding filter box 204 and the circulation box 208. The air pipe 207 is connected to the air outlet 213. A guide pipe 205 is installed at the outer end of the flow-guiding filter box 204. A pressure gauge 206 is inserted into the side wall of the guide pipe 205. A filter element is provided inside the circulation box 208. A pressure module 209 is installed at the side end of the circulation box 208. An air exchange groove 210 is opened on the outer wall of the pressure module 209. The pressure module 209 includes a battery module and an air pump that are electrically connected to each other. The flame-spraying assembly 3 includes a nozzle tube that connects to the adjusting elbow 2, a rotating sleeve 304 and a rotating ring 309 fitted on the nozzle tube, a positive and negative electrode module 303 embedded inside the nozzle tube, and a flow control module 306 coaxially arranged with the rotating ring 309. The flow control module 306 includes a fixing plate 311 fixedly connected to the nozzle tube, a sealing partition 310 coaxially connected to the fixing plate 311, a plurality of airflow holes 312 distributed on the sealing partition 310, a first connecting sleeve 313 and a second connecting sleeve 314 installed at the center of the sealing partition 310, a rotating rod 315 inserted into the first connecting sleeve 313 and the second connecting sleeve 314, one end of the rotating rod 315 fixedly connected to the rotating ring 309, and a rotary joint between the other end of the rotating ring 309 and the fixing plate 311. A plurality of sealing blades 316 are circumferentially fixedly connected to the periphery of the first connecting sleeve 313 and the second connecting sleeve 314. Several sets of counterweights 401 are fixedly connected to the outer end of the arc-starting cover 4. A flame-spraying plate 403 is integrated at the end of the arc-starting cover 4. Several sets of flame holes 404 are distributed on the flame-spraying plate 403. A high-temperature resistant ring 402 is provided between the flame-spraying plate 403 and the arc-starting cover 4.

[0022] During operation, unburned gas enters the gas pipe 207 through the gas outlet 213 and is guided to the circulation box 208. After the filter element (made of stainless steel sintered mesh or ceramic fiber) filters out impurities, the gas is pressurized by the suction pump (specifically a diaphragm micro pump) in the pressure module 209 and then transported back to the nozzle pipe through the air exchange groove 210 to participate in combustion. Pressure gauge 206 and pressure sensor 212 work together to monitor system pressure. The user can manually rotate rotating ring 309 via handle 308, driving rotating rod 315 to adjust the opening and closing degree of airflow orifice 312 by sealing blade 316, thereby controlling gas flow and jet pattern. Multiple sets of flame holes 404 on flame plate 403 (made of high-temperature resistant Inconel 600) disperse the flame. High-temperature resistant ring 402 (ceramic matrix composite material) isolates heat conduction and protects arc ignition cover 4 structure. Battery module powers sensor and pump, and charging module 104 supports external rapid power replenishment.

[0023] The above working principles can be summarized as follows: the adjustable bellows 201 structure and counterweight flame stabilization design are used to deal with airflow disturbances; the gas recovery system and intelligent flow control module 306 are used to realize energy recycling and dynamic adjustment; and the high-temperature resistant materials and modular structure are used to ensure the reliability and maintenance convenience of the system in harsh environments.

[0024] Specifically, the ceramic support plate 214 is made of high-purity alumina ceramic, with a temperature resistance of >1600℃ and good insulation properties.

[0025] Sealing joint 203 and high-temperature resistant sleeve 202: silicone rubber or graphite composite material, temperature range -50℃~400℃.

[0026] Flame jet plate 403 and arc ignition cover 4: nickel-based alloy (Inconel 600) or silicon carbide ceramic, resistant to high temperature corrosion.

[0027] The corrugated pipe is made of 201:316 stainless steel or Inconel 625, which is resistant to fatigue and chemical corrosion.
