Description

Technical Field

[0001] This invention relates to the technical field of flare systems, and in particular to an energy-saving continuous lamp that automatically regulates gas flow based on the principle of thermal expansion and contraction. Background Technology

[0002] As a crucial component of the flare ignition system, the continuous flame lamp directly impacts the safety of timely ignition of the flare gas, making it a critical part of the system and widely used in various flare systems. Currently, traditional continuous flame lamps generally employ a semi-premixed combustion method. Their ejector is located at the bottom of the lamp. Under operating conditions, the high-speed fuel flowing from the fuel nozzle of the lamp body ejects the surrounding air. After the fuel and air mix in the ejector mixing tube, the mixture is delivered to the top of the continuous flame lamp for combustion.

[0003] The energy-saving continuous lamp with Chinese patent application number CN201410090798.3 includes a lamp head windproof cover and a gas burner. The middle part of the gas burner is provided with an ignition gun protective sleeve connected to the ignition gun. The tail of the gas burner is connected to a fuel gas and air premixing chamber. The lower end of the fuel gas and air premixing chamber is provided with an air intake adjustment mechanism. The fuel gas nozzle extends into the lower end of the fuel gas and air premixing chamber and is connected to a fuel gas delivery adjustment mechanism.

[0004] However, during long-term use, the temperature sensing probe of the thermocouple connector is prone to being covered by combustion carbon deposits, which can cause its temperature measurement effect to deteriorate or fail. In addition, the fuel gas inlet of the filter is prone to being blocked by impurities, which can lead to insufficient fuel gas input and thus affect the combustion effect of the lamp. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an energy-saving continuous lamp that automatically adjusts gas flow based on the principle of thermal expansion and contraction.

[0006] The present invention discloses an energy-saving continuous lamp that automatically regulates gas based on the principle of thermal expansion and contraction, comprising a mixing tube, a lamp head provided at the upper end of the mixing tube, a lamp head cover slidably provided at the top of the lamp head, a thermocouple connector provided at the side end of the mixing tube inside the lamp head, a cleaning device provided inside the lamp head, a filter provided at the lower part of the mixing tube, a blockage removal device provided inside the filter, and a filter screen provided inside the filter;

[0007] The cleaning device includes a drive cylinder, and the drive cylinder is filled with a thermally expanding and contracting liquid. The unclogging device includes a turbine blade, a drive shaft is located at the center of the turbine blade, and a scraper is located at the end of the drive shaft. The scraper is inclined and is attached to the filter screen.

[0008] Preferably, the upper end of the mixing tube is provided with an ignition rod connector at the lower end of the lamp head, the lower end of the mixing tube is provided with an ejector at the upper end of the filter, and the mixing tube is also provided with two connecting plates, which are respectively located at the upper and lower parts of the mixing tube.

[0009] Preferably, the lamp head is provided with a round hole, and the lamp head cover is provided with a rectangular hole that matches the round hole.

[0010] Preferably, the cleaning device further includes a first mounting plate, on which a connecting rod is slidably disposed. A scraper ring is disposed on the side of the connecting rod near the thermocouple connector. A transition plate is disposed at the output end of the drive cylinder. One side of the transition plate is connected to the connecting rod, and a push ring is disposed on the other side of the transition plate. The push ring slides at an upper limit on the inner wall of the lamp head.

[0011] Preferably, the unclogging device further includes a second mounting plate, which is disposed inside the inclined tube of the filter. The drive shaft is rotatably mounted on the second mounting plate. An opening is provided on the inclined tube of the filter, and a collection bottle is provided at the opening below the inclined tube of the filter. The opening is located at the lower end of the filter screen.

[0012] Preferably, the scraper has a groove at its end, a push rod is slidably disposed in the groove, the end of the push rod is arc-shaped, a spring is disposed between the push rod and the bottom of the groove, and the size of the push rod is smaller than the opening size.

[0013] Preferably, the inner wall of the lamp head is provided with a limiting groove, and the outer side of the lamp head cover is provided with a limiting slider. When the lamp head cover slides inside the lamp head, it will not rotate due to the action of the limiting groove and the limiting slider.

[0014] Preferably, a temperature sensing probe is provided on one side of the thermocouple connector inside the lamp head, the scraper ring is fitted onto the temperature sensing probe, and all components inside the cleaning device are made of high-temperature resistant materials.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By incorporating components such as a drive cylinder, scraper ring, turbine fan blades, scraper, push rod, and spring, the temperature sensor of the thermocouple connector is prone to temperature drop due to carbon buildup during long-term use of the continuous lamp. In this situation, the system controls the intake valve to increase the volume of gas ejected from the upper end of the mixing pipe, resulting in more intense combustion within the lamp head. Consequently, the actual temperature inside the lamp head rises. During this process, the thermal expansion and contraction of the liquid within the drive cylinder increases its volume, causing the drive cylinder output end to extend. With the assistance of the transition plate and connecting rod, the scraper ring moves on the temperature sensor, thus... The carbon deposits on the temperature sensor are cleaned. At the same time, the movement of the transition plate, assisted by the push ring, moves the lamp head cover, causing the rectangular and round holes to misalign, thus altering the combustion effect of the lamp head. This allows workers to roughly judge the condition of the temperature sensor. Simultaneously, as the intake valve changes, the airflow through the turbine fan blades also changes, thereby changing the speed of the turbine fan blades. This allows the scraper to better clean the impurities on the filter screen. Furthermore, when the scraper passes through the opening, the spring action and push rod push the impurities at the opening into the collection bottle, improving the ease of use of the equipment.

Detailed Implementation

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0019] like Figures 1 to 8 As shown, this invention discloses an energy-saving continuous lamp based on the principle of thermal expansion and contraction with automatic gas regulation. It includes a mixing tube 1, a lamp head 2 at the upper end of the mixing tube 1, a lamp head cover 3 slidably mounted on the top of the lamp head 2, a thermocouple connector 4 inside the lamp head 2 at the side end of the mixing tube 1, a filter 6 at the lower part of the mixing tube 1, an ignition rod connector 9 at the lower end of the lamp head 2 at the upper end of the mixing tube 1, an ejector 10 at the upper end of the mixing tube 1 above the filter 6, and two connecting plates 11 located at the upper and lower parts of the mixing tube 1, respectively. The device is mounted on a torch burner with the assistance of the two connecting plates 11. This design makes the installation and connection of the equipment more stable and less prone to shaking. The wires of the thermocouple connector 4 can also be limited by the holes on the connecting plate 11 to ensure the stable use of the wires. The lamp cover 3 can prevent rain and snow from entering from the top of the lamp head 2, thus preventing the lamp from going out abnormally in rainy or snowy weather. The filter 6 can mix the combustible gas and air entering the mixing tube 1 to ensure complete combustion at the top of the mixing tube 1. The ejector 10 can accelerate the mixing of air and combustible gas to ensure uniform mixing. The ignition rod connector 9 can generate an electric spark at the upper end of the mixing tube 1 to ignite the gas ejected from the mixing tube 1, improving the ease of use of the equipment.

[0020] The lamp holder 2 is also equipped with a cleaning device 5, which includes a drive cylinder 501. The drive cylinder 501 is filled with a thermally expanding and contracting liquid. The thermally expanding and contracting liquid in the drive cylinder 501 will change its volume with the change of temperature, thereby causing the output end of the drive cylinder 501 to move.

[0021] The cleaning device 5 also includes a first mounting plate 502, on which a connecting rod 503 is slidably mounted. A scraper ring 504 is mounted on the side of the connecting rod 503 near the thermocouple connector 4. A transition plate 505 is mounted on the output end of the drive cylinder 501. One side of the transition plate 505 is connected to the connecting rod 503. A temperature sensor is mounted on the side of the thermocouple connector 4 located inside the lamp holder 2. The scraper ring 504 is fitted onto the temperature sensor. All components in the cleaning device 5 are made of high-temperature resistant materials. When the output end of the drive cylinder 501 moves, it will drive the transition plate 505 to move. The movement of the transition plate 505, with the assistance of the connecting rod 503, drives the movement of the scraper ring 504. When the scraper ring 504 moves, it can scrape and clean the combustion carbon deposits on the temperature sensor of the thermocouple connector 4, ensuring the normal use of the temperature sensor.

[0022] The lamp head 2 is provided with a round hole 12, and the lamp head cover 3 is provided with a rectangular hole 13 that matches the round hole 12. A push ring 506 is provided on the other side of the transition plate 505. The push ring 506 slides at the upper limit on the inner wall of the lamp head 2. When the output end of the drive cylinder 501 drives the transition plate 505 to move, the transition plate 505 will also drive the push ring 506 to move. The movement of the push ring 506 will drive the lamp head cover 3 to move, thereby creating a misalignment between the rectangular hole 13 and the round hole 12, so as to change the burning observation effect of the lamp.

[0023] The filter 6 is equipped with a blockage removal device 7 and a filter screen 8. Both the air inlet and the combustible gas inlet of the filter 6 are equipped with air inlet valves. Air passes through the filter 6 from bottom to top and enters the mixing pipe 1, while combustible gas passes through the filter 6 from the side and enters the mixing pipe 1. Since there are many impurities in the combustible gas, a filter screen 8 is often installed at the combustible gas inlet to reduce the amount of impurities entering the filter 6.

[0024] The unclogging device 7 includes a turbine blade 701, a drive shaft 702 is located at the center of the turbine blade 701, and a scraper 703 is located at the end of the drive shaft 702. The scraper 703 is inclined and attached to the filter screen 8. When the airflow passes through the turbine blade 701, it will cause the turbine blade 701 to rotate. The rotation of the turbine blade 701 drives the rotation of the drive shaft 702, thereby causing the scraper 703 to rotate. During the rotation of the scraper 703, impurities on the filter screen 8 can be scraped off, preventing excessive impurities from clogging the filter screen 8.

[0025] The unclogging device 7 also includes a second mounting plate 704, which is disposed inside the inclined tube of the filter 6. The drive shaft 702 is rotatably mounted on the second mounting plate 704. An opening 705 is provided on the inclined tube of the filter 6. A collection bottle 706 is provided below the inclined tube of the filter 6 at the opening 705. The opening 705 is located at the lower end of the filter screen 8. As the inclined scraper 703 rotates, the scraped impurities will be pushed along the edge of the filter screen 8. When the impurities are pushed to the opening 705, they will pass through the opening 705 and be discharged into the collection bottle 706, which improves the ease of use of the equipment.

[0026] The scraper 703 has a groove 707 at its end, and a push rod 708 is slidably disposed in the groove 707. The end of the push rod 708 is arc-shaped, and a spring 709 is disposed between the push rod 708 and the bottom of the groove 707. The size of the push rod 708 is smaller than that of the opening 705. During the rotation of the scraper 703, when the end of the scraper 703 passes through the opening 705, the pressure of the filter 6 on the end of the push rod 708 disappears. Under the action of the spring 709, the push rod 708 extends, pushing the impurities in the opening 705 downwards, so that the impurities can pass smoothly through the opening 705 and enter the collection bottle 706, improving the ease of use of the equipment.

[0027] The inner wall of the lamp head 2 is provided with a limiting groove, and the outer side of the lamp head cover 3 is provided with a limiting slider. When the lamp head cover 3 slides inside the lamp head 2, it will not rotate due to the action of the limiting groove and the limiting slider. The lamp head cover 3 is limited by the limiting groove and the limiting slider to ensure that the rectangular hole 13 and the round hole 12 can be smoothly matched.

[0028] During use, the combustible gas in the torch burner enters the mixing tube 1 through the pipe at the side of the filter 6. At the same time, external air enters the mixing tube 1 from the bottom of the filter 6. The combustible gas and air enter the ejector 10. With the assistance of the ejector 10, the combustible gas and air are fully mixed. Then, the mixer sprays out from the top of the mixing tube 1.

[0029] With the assistance of the ignition rod connector 9, a spark is generated at the upper outlet of the mixing tube 1, thereby igniting the mixed gas ejected from the upper end of the mixing tube 1.

[0030] During the use of the equipment, the lamp head cover 3 helps to block debris from the top, preventing debris from entering the lamp head 2 from the top and affecting the combustion inside the lamp head 2. For example, in rainy or snowy weather, if there is no lamp head cover 3, rain and snow can easily enter the lamp head 2, which can easily extinguish the combustion inside the lamp head 2.

[0031] During long-term use, the mixture inside the lamp head 2 is in a state of continuous combustion. As a result, carbon deposits are easily generated on the temperature sensing probe of the thermocouple connector 4. As carbon deposits accumulate, the test temperature of the temperature sensing probe will gradually decrease. At this time, the system will judge that the combustion effect inside the lamp head 2 has deteriorated, and then control the intake valve to increase. However, in reality, the combustion inside the lamp head 2 will be more intense, causing the temperature inside the lamp head 2 to rise.

[0032] After the temperature inside the lamp head 2 rises, the thermally expanding and contracting liquid inside the drive cylinder 501 expands in volume due to heat, causing the output end of the drive cylinder 501 to extend, which in turn drives the transition plate 505 to move. The movement of the transition plate 505, with the assistance of the connecting rod 503, drives the scraper ring 504 to move. When the scraper ring 504 moves on the temperature sensor, it can scrape off and clean the carbon deposits on the temperature sensor, ensuring that the temperature sensor can perform normal temperature measurement.

[0033] After cleaning the carbon deposits on the temperature sensor, the temperature sensor can accurately detect the temperature inside the lamp head 2, which in turn causes the system to control the intake valve to decrease, reducing the degree of combustion inside the lamp head 2 and lowering the temperature of the lamp head 2. During this process, the thermally expanding and contracting liquid inside the drive cylinder 501 shrinks in volume due to the decrease in temperature. Therefore, the output end of the drive cylinder 501 retracts, causing the transition plate 505 to move toward the drive cylinder 501, which in turn causes the scraper ring 504 to move to its initial position.

[0034] When the airflow passes through the turbine blades 701, it causes the turbine blades 701 to rotate. The rotation of the turbine blades 701 drives the drive shaft 702 to rotate, which in turn causes the scraper 703 to rotate. During the rotation of the scraper 703, impurities on the filter screen 8 can be scraped off, preventing excessive impurities from clogging the filter screen 8.

[0035] As the tilted scraper 703 rotates, the scraped impurities are pushed along the edge of the filter screen 8. When the impurities are pushed to the opening 705, they are discharged through the opening 705 into the collection bottle 706, which improves the ease of use of the equipment.

[0036] During the rotation of scraper 703, when the end of scraper 703 passes through opening 705, the pressure of filter 6 on the end of push rod 708 disappears. Under the action of spring 709, push rod 708 extends and pushes the impurities in opening 705 downward, so that the impurities can pass through opening 705 smoothly into collection bottle 706, improving the convenience of equipment use. After push rod 708 passes through opening 705, it is subjected to the pressure of the side wall of filter 6 and push rod 708 retracts back into groove 707.

[0037] When the transition plate 505 moves away from the drive cylinder 501, the movement of the transition plate 505 will also drive the push ring 506 to move. The movement of the push ring 506 can push the lower end of the lamp cover 3, causing the lamp cover 3 to move. The movement of the lamp cover 3 is limited by the limiting groove and the limiting slider. During this process, the rectangular hole 13 and the round hole 12 will be misaligned to change the combustion observation effect of the lamp. At this time, the worker can roughly judge the operating status of the temperature probe of the thermocouple connector 4 by simply observing the combustion effect of the lamp.

[0038] During the cleaning process of the temperature sensor, the system controls the change of the intake valve, which in turn changes the airflow through the turbine blades 701. As a result, the rotation speed of the turbine blades 701 also changes accordingly, which in turn changes the rotation speed of the scraper 703. This change in the rotation speed of the scraper 703 helps to scrape away stubborn impurities on the filter screen 8, making the cleaning effect of the equipment on the filter screen 8 better.

[0039] The main function achieved by this invention is as follows: By setting components such as drive cylinder 501, scraper ring 504, turbine fan blade 701, scraper 703, push rod 708, and spring 709, during the long-term use of the lamp, the temperature sensing probe of the thermocouple joint 4 is prone to a drop in the detected temperature due to carbon buildup. At this time, the system will control the intake valve to increase, so that more gas is ejected from the upper end of the mixing pipe 1, thereby making the combustion in the lamp head 2 more intense. Therefore, the actual temperature in the lamp head 2 will rise. During this process, the volume of the liquid in the drive cylinder 501 increases due to thermal expansion and contraction, causing the output end of the drive cylinder 501 to extend. With the assistance of the transition plate 505 and the connecting rod 503, the scraper ring 504 moves to the temperature sensing probe. The upward movement of the transition plate 505 cleans the carbon deposits on the temperature sensor. Simultaneously, the movement of the transition plate 505, assisted by the push ring 506, causes the lamp head cover 3 to move, resulting in a misalignment between the rectangular hole 13 and the round hole 12. This alters the combustion effect of the lamp head 2, allowing workers to roughly assess the condition of the temperature sensor. Furthermore, the change in the intake valve alters the airflow through the turbine blades 701, changing their rotational speed. This allows the scraper 703 to better clean impurities from the filter screen 8. Additionally, when the scraper 703 passes through the opening 705, the push rod 708, aided by the spring 709, pushes the impurities at the opening 705 into the collection bottle 706, improving the ease of use of the equipment.
