Description

Technical Field

[0001] This utility model relates to the technical field of ignition devices for torch systems, specifically a continuous lamp that can adapt to harsh weather conditions. Background Technology

[0002] A flare is an industrial device used to incinerate combustible waste gases (such as refinery gas, toxic gases, biogas, etc.), converting them into low-hazard substances such as carbon dioxide and water through combustion, thus combining safe emission and environmental protection functions. Existing industrial flare styles include elevated flares, enclosed ground flares, and open ground flares.

[0003] For large-volume, intermittent emissions of flammable and toxic gases, flare systems are suitable. According to the standard "Design Code for Flammable Gas Emission Systems in Petrochemical Industries" (SH3009-2013), each flare should be configured with a specific number of flares based on its diameter, and the continuous lighting lamps must be constantly lit. Given the current energy conservation and emission reduction efforts in various industries, available fuel gas within the plant is often used as fuel for these continuous lighting lamps. However, in harsh environments such as low-calorific-value fuels, high wind speeds, high humidity, and rainy weather, the unstable environmental conditions cause existing continuous lighting lamps to malfunction. Especially during the rainy season in southern China, the ignition electrodes frequently malfunction. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and proposes a continuous light that can adapt to severe weather conditions; it solves the problem that continuous lights cannot work stably in severe weather environments.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A continuous light capable of adapting to harsh weather conditions includes an adjustment plate, a nozzle, an ejector tube, a mixing tube, and a flame generator. The nozzle has a converging conical nozzle at its front end, and its rear end is connected to an air supply pipe. The conical nozzle portion at the front end of the nozzle is located inside the ejector tube, which has an open bottom structure. The open structure is connected to the external atmosphere. The top of the ejector tube is connected to the bottom of the mixing tube, and the top of the mixing tube is connected to the flame generator. The ejector tube has a converging conical structure from bottom to top, with the narrowing at the top forming an ejector opening. An adjustment plate is threaded onto the outer wall of the air supply pipe to adjust the distance between the adjustment plate and the open structure.

[0007] Furthermore, long spiral ignition electrodes are symmetrically arranged on one side of the flame generator, with the electrode heads of the two long spiral ignition electrodes facing each other and close to the flame generator.

[0008] Furthermore, a secondary combustion-supporting air cap is installed at the flame generator. The secondary combustion-supporting air cap is a double-layered, open-top cylindrical structure. The secondary combustion-supporting air cap surrounds the flame generator and is fixed to the outside of the flame generator. Multiple staggered openings are provided on the double-layered sidewalls of the secondary combustion-supporting air cap.

[0009] Furthermore, a windproof cover is installed around the outside of the secondary combustion-supporting wind cap; the windproof cover is a double-layered, open-top cylindrical structure, and multiple staggered openings are provided on the double-layered sidewalls of the windproof cover.

[0010] Furthermore, a wind shield is added to the bottom of the wind shield, with a gap between the wind shield and the wind shield.

[0011] Furthermore, an arc-shaped rain shield is installed above the flame generator, with both sides of the rain shield connected to the windproof cover.

[0012] The beneficial effects of this utility model compared to the prior art are as follows:

[0013] This invention uses a long spiral ignition electrode to increase the conductive spacing and prevent high voltage from breaking down the air. At the same time, a special sealing process is used to seal the assembly gap of the long spiral ignition electrode and form a ceramic-like sealing surface, which increases the temperature resistance of the long spiral ignition electrode and prevents water and water vapor from entering the interior, ensuring that the ignition electrode can work stably for a long time.

[0014] This invention solves the problem of unstable operation of the continuous lamp in harsh environments such as high wind speed, high humidity, and rainy weather, and overcomes the problem of the lamp easily going out and being difficult to restart after going out. It also works with low-calorific-value gas (5-14 MJ / Nm³). 3 The power consumption of the lamp during operation is 3-1.5 Nm. 3 It can operate stably with a gas consumption of no more than 3 Nm³ / h under conditions of low-calorific-value fuel gas and high wind speed. 3 / h.

[0015] In addition to being adaptable to low-calorific-value gas, high wind speed, and the rainy season, this utility model also significantly reduces the gas consumption of enterprises, providing favorable conditions for enterprises to make full use of existing resources while saving investment.

[0022] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0023] See Figures 1 to 4 This embodiment proposes a continuous light that can adapt to severe weather, including an adjustment plate 1, a nozzle 2, an ejector tube 4, a mixing tube 5, a flame generator 6, a secondary combustion-supporting wind cap 7, a windproof cover 8, a long spiral ignition electrode 9, a rain shield 10, a wind shield 11, and a deflagration tube 12.

[0024] The nozzle 2 has a converging conical nozzle at its front end, and the nozzle 2 adopts the Venturi nozzle principle. The rear end of the nozzle 2 is connected to the gas inlet pipe 13. The conical nozzle part at the front end of the nozzle 2 is located inside the ejector tube 4, and the bottom of the ejector tube 4 is an open structure 14. The open structure 14 is connected to the external atmospheric environment. The top of the ejector tube 4 is connected to the bottom of the mixing pipe 5. The bottom of the mixing pipe 5 and the top of the ejector tube 4 are welded to form a transmission channel for conveying the mixed gas. The top of the mixing pipe 5 is connected to the flame generator 6. The ejector tube 4 is a converging conical structure from bottom to top, and the narrowing part at the top of the ejector tube 4 forms the ejector port 3. When the fuel gas enters the nozzle 2 through the gas inlet pipe 13, the converging conical nozzle will increase the fuel gas velocity and decrease the static pressure, forming a negative pressure zone at the ejector port 3. External air will be drawn into the ejector tube 4 from the open structure 14 to form a primary combustion air. Then, the primary combustion air is introduced through the ejector tube 4 and mixed with the fuel gas in the mixing pipe 5 and enters the flame generator 6.

[0025] The outer wall of the air inlet pipe 13 is threaded, and an annular adjusting plate 1 is connected to the outer wall of the air inlet pipe 13 via the thread. The distance between the adjusting plate 1 and the open structure 14 at the bottom of the ejector pipe 4 is adjustable. When the adjusting plate 1 is rotated close to the open structure 14, the connection between the open structure 14 and the external atmosphere is gradually reduced, which can reduce the amount of air entering the ejector pipe 4. When the adjusting plate 1 is rotated away from the open structure 14, the connection between the open structure 14 and the external atmosphere is gradually increased, which can increase the amount of air entering the ejector pipe 4. That is, the air intake volume of the primary combustion air can be adjusted by adjusting the position of the adjusting plate 1 in the air inlet pipe 13.

[0026] Symmetrically arranged on one side of the flame generator 6 are long spiral ignition electrodes 9. These are existing structures, with the electrode heads of the two long spiral ignition electrodes 9 facing each other and close to the flame generator 6. The gas mixture enters the mixing pipe 5 and is delivered to the flame generator 6. At this point, the long spiral ignition electrodes 9 ignite the gas mixture, allowing the automatic lamp to operate normally. A main flame forms in the center of the flame generator 6, surrounded by multiple mother flames, ensuring flame stability. During the rainy season in southern China, traditional automatic lamps are prone to failure. Using long spiral ignition electrodes 9 increases the conductive spacing, preventing high-voltage breakdown of the air and ensuring long-term stable operation of the ignition electrodes.

[0027] When the wind speed at high altitude is 40 m / s, traditional continuous lights are easily extinguished. To solve this problem, a secondary combustion-supporting air cap 7 is installed at the flame generator 6. The secondary combustion-supporting air cap 7 is a double-layered, open-top cylindrical structure. The secondary combustion-supporting air cap 7 is fixed to the outside of the flame generator 6. Multiple staggered openings are provided on the double-layered sidewalls of the secondary combustion-supporting air cap 7. The secondary combustion-supporting air cap 7 can reduce the impact of crosswinds at high altitude on the flame of the flame generator 6, and the staggered openings on it provide a fixed small air volume for the flame generator 6, compensating for the adjustment accuracy of the primary combustion-supporting air.

[0028] A windproof cover 8 is installed outside the secondary combustion-supporting wind cap 7; the top of the deflagration tube 12 is located inside the windproof cover 8; the windproof cover 8 is surrounded by a multi-hole staggered structure. When high-altitude crosswinds reach the windproof cover 8, the high-speed high-altitude winds passing through the windproof cover 8 are separated into multiple small-flow high-altitude winds and the wind speed is reduced, thus reducing the impact of high-altitude winds on the flame. In addition to providing secondary combustion-supporting air to increase flame reliability, the secondary combustion-supporting wind cap 7 also has a windproof function, which can assist the windproof cover 8 in playing a better role in preventing crosswinds.

[0029] The flame of the continuous lamp exerts a vacuum suction force on the bottom of the windproof cover 8. The wind at the bottom of the windproof cover 8 draws the flame from the flame generator 6, causing the continuous lamp flame to extinguish. To solve this problem, a wind shield 11 is added to the bottom of the windproof cover 8, with a gap between the wind shield 11 and the windproof cover 8. The flow area of ​​the wind shield 11 can be adjusted according to the high-altitude wind speed and the suction force generated by the combustion flame of the fuel gas. Using Aspen software, common wind speeds, fuel gas, and fuel gas with a wind speed of 35~40 m / s and a calorific value not exceeding 5 MJ were used as input conditions for modeling and simulation to determine the flow area. Adjusting the gap of the wind shield 11 and the air intake at the bottom of the windproof cover 8 prevents the flame at the flame generator from detaching and extinguishing.

[0030] An arc-shaped rain shield 10 is installed above the flame generator 6, and the two sides of the rain shield 10 are connected to the windproof cover 8; the rain shield 10 increases the reliability of the long spiral ignition electrode 9 when working in rainy weather. Adding the rain shield 10 adds another layer of protection against rain.

[0031] The working principle of the all-weather lamp described in this embodiment is as follows:

[0032] A small amount of fuel gas (calorific value 5-14 MJ / h) is introduced into the nozzle 2 through the gas inlet pipe 13 to increase the gas flow rate, creating a negative pressure zone at the injector 3. The size of the negative pressure zone is adjusted by adjusting the distance between the threaded adjusting plate 1 and the open structure 14, thereby adjusting the air volume of the primary combustion air for the continuous lamp. The fuel gas and primary combustion air are mixed in the mixing pipe 5 and transported to the flame generator 6 through the pipeline. At this time, the long spiral ignition electrode 9 starts to work, igniting the mixed gas to form a stable flame. The flame generator 6 is an existing structure, and its function is to form a flame. The flame generator 6 consists of a central main flame and multiple mother flames. The mother flames are lower than the main flame. When the main flame goes out, the surrounding mother flames re-ignite the main flame when the main flame gas is ejected, ensuring the stable operation of the continuous lamp and reducing the frequency of continuous lamp ignition cycles.

[0033] The secondary combustion accelerator 7 not only provides secondary combustion air to increase flame reliability but also serves a windproof function, assisting the wind shield 8 in better preventing crosswinds. A wind shield 11 is added to the bottom of the wind shield 8; the air intake at the bottom of the wind shield 8 is adjusted according to the size of the wind shield 11 to prevent the flame at the flame generator from extinguishing due to flame detachment. A rain shield 10 is added for an additional layer of rain protection.

[0034] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered to fall within the scope of patent protection determined by the submitted claims.
