Technical Field

[0001] This utility model belongs to the field of burner ignition technology, and more specifically, relates to a multi-gas combined continuous lamp, an aerial torch, and a ground torch. Background Technology

[0002] Petrochemical, coal chemical, and other chemical plants generate large amounts of flammable and hazardous waste gases during production. These gases require combustion treatment via high-altitude or ground-based flares before being released into the atmosphere. Currently, continuous-burning lamps serve as the ignition source for the flare burners, using natural gas or liquefied petroleum gas (LPG) as the combustion gas. The annual consumption is substantial; for a large-scale oil refinery or coal chemical plant, the annual energy cost exceeds hundreds of millions of yuan. This also results in significant environmental pollution. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-gas combined continuous lamp, high-altitude flare, and ground flare. This multi-gas combined continuous lamp is suitable for combustible waste gases emitted from oil refineries and coal chemical plants with multiple components. By using combustible waste gases as the gas source for the continuous lamp, energy consumption, environmental pollution, and production and operating costs can be minimized.

[0004] To achieve the above objectives, this utility model provides a multi-gas combined continuous lamp, comprising:

[0005] A concave low-pressure gas nozzle includes a low-pressure concave bottom bevel and a low-pressure concave side hole. A high-pressure gas nozzle is provided on the outer periphery of the concave low-pressure gas nozzle. Multiple high-pressure gas nozzle holes are designed at the top of the high-pressure gas nozzle. The concave low-pressure gas nozzle is connected to a low-pressure explosion-proof breather valve through a low-pressure mixed fuel gas pipe. A low-pressure closed venturi tube is provided on the low-pressure mixed fuel gas pipe. The high-pressure gas nozzle is connected to a high-pressure explosion-proof breather valve through a high-pressure mixed fuel gas pipe. A high-pressure closed venturi tube is provided on the high-pressure mixed fuel gas pipe.

[0006] A direct-fired gas nozzle has a V-shaped lower part and a cylindrical upper part. The cylindrical gas nozzle is located at the center of the direct-fired gas nozzle. Multiple gas holes are provided on the circumference and bottom of the cylindrical nozzle. A hydrogen-containing gas nozzle is located at the center of the bottom of the cylindrical gas nozzle. The hydrogen-containing gas nozzle is connected to a hydrogen-containing gas pipe. A fuel gas thermocouple is located on the outer wall of the upper cylindrical part of the direct-fired gas nozzle.

[0007] The circular concave low-pressure gas nozzle, the high-pressure gas nozzle, and the direct-fired gas nozzle are arranged in the same combined combustion chamber, which is connected to the inlet of the deflagration tube.

[0008] Optionally, the high-pressure closed-loop venturi tube is connected to a high-pressure fuel gas pipe, and the high-pressure closed-loop venturi tube is also connected to a high-pressure air pipe, the inlet of which is equipped with a high-pressure air regulating valve.

[0009] Optionally, the low-pressure closed-loop venturi tube is connected to a low-pressure gas pipe, and the low-pressure closed-loop venturi tube is also connected to a low-pressure air pipe. A low-pressure air regulating valve is provided at the inlet of the low-pressure air pipe, and a gas thermocouple is installed inside the low-pressure mixed fuel gas pipe.

[0010] Optionally, the middle part of the high-pressure mixed fuel gas pipe is connected to the ignition sleeve, and the bottom of the ignition sleeve is provided with an ignition electrode.

[0011] Optionally, the system also includes a three-way gas valve, which is connected to a combustible gas pipeline. The high-pressure outlet and low-pressure outlet of the three-way gas valve are respectively connected to the inlet of the high-pressure fuel gas pipeline and the inlet of the low-pressure gas pipeline. The three-way gas valve is equipped with a normally closed spring-sealed plunger and a normally open spring-sealed plunger.

[0012] Optionally, the gas three-way valve is further provided with a first movable plunger and a second movable plunger. The first movable plunger is connected to the normally closed spring sealing plunger, and the second movable plunger is connected to the normally open spring sealing plunger. When combustible gas enters the gas three-way valve, the normally open spring sealing plunger is in the open state, and the combustible gas enters the low-pressure gas pipe through the low-pressure outlet. When the combustible gas pressure of the gas three-way valve increases, the second movable plunger pushes the normally open spring sealing plunger to close, and the first movable plunger pushes the normally closed spring sealing plunger to open, and the combustible gas enters the high-pressure air pipe through the high-pressure outlet. When the pressure decreases, the operation returns to the initial state.

[0013] Optionally, the outer periphery of the hydrogen-containing gas nozzle is provided with a perforated plate, and a cylindrical gas nozzle is provided at the lower end of the perforated plate.

[0014] This utility model also provides a high-altitude flare, including the aforementioned multi-gas combined continuous lamp. The low-pressure closed venturi tube and the high-pressure closed venturi tube are installed at the bottom of the high-altitude flare tower. The direct-fired gas nozzle is connected to the fuel gas thermocouple. The high-pressure closed venturi tube is connected to the high-pressure air pipe. The low-pressure closed venturi tube is connected to the low-pressure air pipe. The fuel gas thermocouple, the high-pressure air pipe, and the low-pressure air pipe extend to the ground safety area of ​​the high-altitude flare.

[0015] This utility model also provides a ground flare, including the aforementioned multi-gas combined continuous lamp, wherein the direct-fired gas nozzle is connected to a fuel gas thermocouple, the high-pressure closed venturi tube is connected to a high-pressure air pipe, and the low-pressure closed venturi tube is connected to a low-pressure air pipe. When the ground flare is an open ground flare, the low-pressure closed venturi tube, the high-pressure closed venturi tube, the fuel gas thermocouple, the high-pressure air pipe, and the low-pressure air pipe extend to a safe area outside the radiation wall. When the ground flare is a closed ground flare, the low-pressure closed venturi tube, the high-pressure closed venturi tube, the fuel gas thermocouple, the high-pressure air pipe, and the low-pressure air pipe extend to a safe area outside the windbreak wall.

[0016] This utility model provides a multi-gas combined continuous lamp, an high-altitude flare, and a ground flare. Its advantages are as follows: the continuous lamp uses combustible waste gases of different components and pressures as its combustion gas source, employing different combustion methods. Combustible gas is burned using a closed-loop Venturi tube regulated combustion lamp, hydrogen-containing direct-fired combustion lamp, or high-pressure direct-fired combustion lamp. Furthermore, the continuous lamp can automatically switch combustion methods according to the pressure of the combustible waste gas, ensuring normal combustion. The closed-loop Venturi tube of the multi-gas combined continuous lamp places regulating valves on the high and low pressure air pipes at the bottom of the flare tower, outside the radiation wall of the open flare, and outside the windbreak wall of the closed flare. This facilitates observation of the combustion situation and adjustment of the fuel gas intake, thus meeting the safety emission standards for flare burners.

Detailed Implementation

[0028] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0029] This utility model provides a multi-gas combined continuous lamp, including:

[0030] A concave low-pressure gas nozzle includes a low-pressure concave bottom bevel and a low-pressure concave side hole. A high-pressure gas nozzle is provided on the outer periphery of the concave low-pressure gas nozzle. Multiple high-pressure gas nozzle holes are designed at the top of the high-pressure gas nozzle. The concave low-pressure gas nozzle is connected to a low-pressure explosion-proof breather valve through a low-pressure mixed fuel gas pipe. A low-pressure closed venturi tube is provided on the low-pressure mixed fuel gas pipe. The high-pressure gas nozzle is connected to a high-pressure explosion-proof breather valve through a high-pressure mixed fuel gas pipe. A high-pressure closed venturi tube is provided on the high-pressure mixed fuel gas pipe.

[0031] The direct-fired gas nozzle has a V-shaped lower part and a cylindrical upper part. The cylindrical gas nozzle is located in the center of the direct-fired gas nozzle. Multiple gas holes are provided on the circumference and bottom of the cylindrical nozzle. A hydrogen-containing gas nozzle is located in the center of the bottom of the cylindrical gas nozzle. The hydrogen-containing gas nozzle is connected to a hydrogen-containing gas pipe. The fuel gas thermocouple is located on the outer wall of the upper cylinder of the direct-fired gas nozzle.

[0032] The concave low-pressure gas nozzle, the high-pressure gas nozzle, and the direct-fired gas nozzle are arranged in the same combined combustion chamber, which is connected to the inlet of the deflagration tube.

[0033] Specifically, in this continuous light, high-pressure fuel gas enters the high-pressure gas nozzle through a high-pressure sealed venturi tube. Simultaneously, the high-pressure fuel gas also enters the ignition bushing, which contains an ignition electrode. The spark generated by the ignition electrode ignites the high-pressure gas. The ignited flame is transmitted through the ignition bushing to the high-pressure gas nozzle, igniting it. When low-pressure gas enters the concave low-pressure gas nozzle through a low-pressure sealed venturi tube and is ejected, it can be ignited by the ignited high-pressure gas nozzle. Hydrogen-containing gas enters the hydrogen-containing gas nozzle through a pipe and is ejected, sequentially entering the cylindrical gas nozzle, then passing through a perforated plate. Finally, the flame from the already ignited high-pressure gas nozzle ignites the hydrogen-containing gas nozzle, ejecting the hydrogen-containing gas and ultimately igniting the continuous light. Of course, other combustible gases can also be burned. The direct-fired gas nozzle directly injects gas, suitable for gases with a high hydrogen content or high combustible pressure. This allows the injected gas to directly combust with the mixture in the combustion chamber, solving the problem of backfire in the flare burner and addressing its adaptability to various gas compositions. This flare burner can burn various components and different gases. An adjustable damper is installed on the air duct connected to the nozzle in the direct-fired flare burner, allowing for airflow control by adjusting the air duct valve during flare operation.

[0034] By selecting the flame emitted through the deflagration tube inlet, different combustion gas sources can be ignited, such as the combustible gas emitted from the concave low-pressure gas nozzle, high-pressure gas nozzle, and direct-fired gas nozzle. This can meet the safety requirements for the emission combustion of the flare burner.

[0035] By placing a high-pressure gas nozzle on the outer periphery of a concave low-pressure gas nozzle to form a combined continuous lamp, this design primarily addresses the problem of existing continuous lamps being unable to meet the combustion requirements of combustible gases with different compositions. Currently, continuous lamps use natural gas and liquefied petroleum gas (LPG), and cannot use other combustible gases as combustion sources. This combined continuous lamp, however, can spray different types of combustible gases from the nozzle for combustion. The natural gas mixture is sprayed out through the high-pressure gas nozzle, while other combustible gas mixtures are sprayed out through the concave low-pressure gas nozzle, thus achieving normal combustion of the continuous lamp.

[0036] In one embodiment, the high-pressure gas nozzle is connected to the high-pressure explosion-proof breather valve via a high-pressure mixed fuel gas pipe, and a high-pressure closed venturi tube is provided on the high-pressure mixed fuel gas pipe. Similarly, the corresponding low-pressure gas nozzle is connected to the low-pressure explosion-proof breather valve via a low-pressure mixed fuel gas pipe, and a low-pressure closed venturi tube is provided on the low-pressure mixed fuel gas pipe.

[0037] Optionally, the high-pressure closed-loop venturi tube is connected to the high-pressure fuel gas pipe, and the high-pressure closed-loop venturi tube is also connected to the high-pressure air pipe, the inlet of which is equipped with a high-pressure air regulating valve.

[0038] Optionally, the low-pressure closed-loop venturi tube is connected to the low-pressure gas pipe, and the low-pressure closed-loop venturi tube is also connected to the low-pressure air pipe. The inlet of the low-pressure air pipe is equipped with a low-pressure air regulating valve, and a gas thermocouple is installed inside the low-pressure mixed fuel gas pipe.

[0039] Specifically, gas thermocouples are installed in the gas pipelines of different continuously lit lamps to detect gas temperature. A DCS or PLC control cabinet can be used to collect combustion temperature data per unit time. The temperature is then compared with the temperature of the previous unit cycle via software. If the temperature is within a certain deviation range, combustion is considered normal. However, if the temperature difference between two consecutive cycles is lower than a set range, the control cabinet issues an alarm, indicating that the gas temperature of the continuously lit lamp is abnormal.

[0040] The combined continuous light is equipped with high-calorific-value and low-calorific-value closed venturi tubes. The air pipe connected to the closed venturi tubes is installed at the bottom of the elevated flare tower, outside the open flare radiation shield. A regulating valve and flow meter are installed at the inlet end of the air pipe to achieve precise control of the air flow. An explosion-proof breather valve is installed at the inlet of the venturi tube to prevent gas leakage.

[0041] The existing venturi nozzles have their gas nozzle inlets open to the atmosphere, making automatic air control impossible. They lack flow meters and regulating valves. Furthermore, the existing venturi nozzles are located at the top of elevated flares, within the intense radiation range of open flares, making them susceptible to backfire and extinguishing due to weather conditions and the presence of combustible gases. They also cannot enable online maintenance and adjustment of the air dampers during flare operation.

[0042] A gas thermocouple is installed inside or outside the low-pressure mixed fuel gas pipe to detect the gas temperature. When the automatic start-up lamp is running, the temperature is continuously transmitted to the DCS control system via the gas thermocouple. The DCS control system monitors the gas temperature in real time. When the temperature in the low-pressure mixed fuel gas pipe exceeds 80°C, the gas thermocouple sends a high-temperature signal to the DCS control cabinet. The DCS control cabinet then promptly adjusts the low-pressure air regulating valve and the low-pressure gas pipe, thus preventing the automatic start-up lamp from burning out due to backfire. The control principle for other high-calorific-value gas thermocouples is the same. Alternatively, the gas thermocouple can be installed outside the low-pressure mixed fuel gas pipe; the control methods and installation for other gases are the same.

[0043] Optionally, the middle part of the high-pressure mixed fuel gas pipe is connected to the ignition sleeve, and the bottom of the ignition sleeve is provided with an ignition electrode.

[0044] Optionally, it also includes a gas three-way valve, which is connected to a combustible gas pipeline. The high-pressure outlet and low-pressure outlet of the gas three-way valve are respectively connected to the inlet of the high-pressure fuel gas pipeline and the inlet of the low-pressure gas pipeline. The gas three-way valve is equipped with a normally closed spring sealing plunger and a normally open spring sealing plunger.

[0045] Optionally, the gas three-way valve is further provided with a first movable plunger and a second movable plunger. The first movable plunger is connected to a normally closed spring-sealed plunger, and the second movable plunger is connected to a normally open spring-sealed plunger. When combustible gas enters the gas three-way valve, the normally open spring-sealed plunger is in the open state, and the combustible gas enters the low-pressure gas pipe through the low-pressure outlet. When the combustible gas pressure of the gas three-way valve increases, the second movable plunger pushes the normally open spring-sealed plunger to close, and the first movable plunger pushes the normally closed spring-sealed plunger to open, and the combustible gas enters the high-pressure air pipe through the high-pressure outlet. When the pressure decreases, the operation returns to the initial state.

[0046] Specifically, the gas three-way valve controls and switches the multi-gas combined continuous-burner lamp for exhaust gases with different component pressures. When gas enters the three-way valve, it connects to the low-pressure gas pipe through the normally open spring-sealed plunger and the low-pressure outlet. When the gas pressure increases, the first moving plunger moves upon entering the three-way valve, pushing the normally closed spring-sealed plunger open; simultaneously, the second moving plunger moves, pushing the normally open spring-sealed plunger closed. This achieves gas switching from low pressure to high pressure. If the gas pressure decreases, both sealing plungers return to their original state. This gas three-way valve automatically switches the combustion nozzle of the continuous-burner lamp by changing the gas pressure. The gas three-way valve is connected to the feed gas pipeline, and the DCS control cabinet is used to select the fuel gas system for the continuous-burner lamp. When natural gas is selected, the fuel gas pipe connected to the gas three-way valve is connected to the natural gas system, and the natural gas is connected to the high-calorific-value nozzle through the normally closed outlet of the three-way valve. Thus, the high-calorific-value nozzle of the continuous-burner lamp sprays natural gas for combustion. When selecting combustible waste gas from an oil refinery or chemical plant, the normally open outlet of the gas tee is connected to the combustible waste gas system of the oil refinery or chemical plant. This allows the low-calorific-value nozzle of the continuous-burning lamp to spray the combustible waste gas from the oil refinery or chemical plant for combustion. The gas tee valve switches between high-calorific-value combustion by adjusting the pressure, switching between combustion from the continuous-burning lamp to the combustible waste gas source generated by the oil refinery or chemical plant.

[0047] Optionally, a perforated plate is provided on the outer periphery of the hydrogen-containing gas nozzle, and a cylindrical gas nozzle is provided at the lower end of the perforated plate.

[0048] This utility model also provides a high-altitude flare, including the aforementioned multi-gas combined continuous lamp, a low-pressure closed venturi tube and a high-pressure closed venturi tube installed at the bottom of the high-altitude flare tower, a direct-fired gas nozzle connected to a fuel gas thermocouple, a high-pressure closed venturi tube connected to a high-pressure air pipe, a low-pressure closed venturi tube connected to a low-pressure air pipe, and the fuel gas thermocouple, high-pressure air pipe and low-pressure air pipe extending to the ground safety area of ​​the high-altitude flare.

[0049] This utility model also provides a ground flare, including the aforementioned multi-gas combined continuous lamp, a direct-fired gas nozzle connected to a fuel gas thermocouple, a high-pressure closed venturi tube connected to a high-pressure air pipe, and a low-pressure closed venturi tube connected to a low-pressure air pipe. When the ground flare is an open ground flare, the low-pressure closed venturi tube, the high-pressure closed venturi tube, the fuel gas thermocouple, the high-pressure air pipe, and the low-pressure air pipe extend to a safe area outside the radiation wall. When the ground flare is a closed ground flare, the low-pressure closed venturi tube, the high-pressure closed venturi tube, the fuel gas thermocouple, the high-pressure air pipe, and the low-pressure air pipe extend to a safe area outside the windbreak wall.

[0050] Specifically, when a combined continuous lamp is used in an high-altitude flare, a low-pressure air regulating valve is installed at the inlet of the low-pressure air pipe. By extending the low-pressure air pipe, the low-pressure air regulating valve is extended to a safe area on the tower ground for convenient operation. When this continuous lamp is used in an open flare, a low-pressure air regulating valve is installed at the inlet of the low-pressure air pipe and is located in a safe area outside the radiation strong zone. When this continuous lamp is used in a closed ground flare, a low-pressure air regulating valve is installed at the inlet of the low-pressure air pipe and is located in a safe area outside the windbreak wall. This allows the air damper to be adjusted at any time according to the combustion status of the combined continuous lamp, thereby controlling the airflow.

[0051] When a combined continuous light is used with an high-altitude flare, the low-pressure enclosed venturi tube is extended and installed at the lowest point of the tower in a safe area for easy operation. When the same continuous light is used with an open flare, the enclosed venturi tube is extended to a safe area outside the area with strong radiation. The installation method of the high-pressure air pipe and the low-pressure air pipe is the same and will not be described further. The above design structure facilitates operation by personnel.

[0052] In addition, the proper combustion of the pilot light is ensured by monitoring the combustion chamber thermocouple installed within the combined combustion chamber. When a direct-fired gas nozzle is selected to ignite the pilot light, small holes are provided at the bottom and side of the nozzle, and a regulating valve is installed after the hydrogen-containing air pipe extends to the bottom of the tower. This allows for monitoring of the flame combustion via the combustion chamber thermocouple, and adjustment of the air intake via the regulating valve at the bottom of the tower, ensuring the proper combustion of the pilot light. When this pilot light is used in a ground-based flare, its installation structure is the same as that of an elevated flare.

[0053] Furthermore, closed-loop Venturi tubes are installed at the bottom of elevated flare towers and outside the radiation shielding walls of ground-based open flares within a safe area. These closed-loop Venturi tubes are connected to air and fuel gas pipelines. Regulating valves and flow meters are installed on the air pipelines, and regulating valves are installed on the fuel gas pipelines. The air and fuel gas regulating valves are remotely controlled via a DCS control cabinet, enabling real-time monitoring of the gas and air flow to the flare. The combined closed-loop Venturi tubes for the flare are installed outside the radiation shielding walls at the bottom of the tower and outside the safe area of ​​ground-based open flares. Online maintenance of the closed-loop Venturi tubes can be performed at any time, and nozzles can be replaced and air valves adjusted according to the actual composition and pressure of the fuel gas, enabling remote control of the flare.

The direct-fired gas nozzle 30 has a cylindrical V-shaped design, with a cylindrical gas nozzle 29 inside. Multiple small holes are provided on the side walls and bottom of the cylindrical gas nozzle 29. The cylindrical gas nozzle 29 is connected to a hydrogen-containing gas nozzle 27, and a perforated plate 28 is provided at the top of the cylindrical gas nozzle 29. In this way, the two nozzles in the continuous light lamp can burn independently or simultaneously.

[0068] In addition, this multi-gas combined-type continuous-burning lamp also employs a combination of a high-pressure mixed fuel gas pipe 36 and a low-pressure mixed fuel gas pipe. A concave low-pressure gas nozzle 11 is embedded within a high-pressure gas nozzle 12, and combustion occurs within the same combined combustion chamber 13. Since the high-pressure mixed fuel gas pipe 36 is interconnected with the ignition sleeve 15, the high-pressure mixed fuel gas also fills the ignition sleeve 15. An ignition electrode 14 is installed at the lower end of the ignition sleeve 15, generating an electric spark that ignites the combustible gas within the ignition sleeve 15. This combustible gas then ignites the combustible gas ejected from the concave low-pressure gas nozzle 11. A combustion chamber thermocouple is installed within the combined combustion chamber 13 to monitor the temperature stability within the combustion chamber, ensuring stable combustion of the continuous-burning lamp. High-pressure fuel gas enters a high-pressure closed venturi tube 17, and the gas is ejected from the high-pressure gas nozzle 12 through the high-pressure mixed fuel gas pipe 36 for combustion. A gas thermocouple 16 installed within the pipe monitors the gas temperature in real time to ensure normal combustion of the continuous-burning lamp.

[0069] In this multi-gas combined continuous lamp, the low-pressure closed venturi tube and the high-pressure closed venturi tube have the same structure. Air enters the sealed cavity 41 from the air inlet 39 of the closed venturi tube, and combustible gas enters from the combustible gas inlet 38 of the closed venturi tube, and then enters the sealed cavity 41 through the combustible gas nozzle 40. After the fuel gas and air gas are mixed in the sealed cavity 41, they finally flow out of the closed venturi tube from the mixed gas outlet 42.

[0070] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
