Description

Technical Field

[0001] The utility model relates to the application field of a chemical flare head, in particular to a smoke elimination type flare head. Background Art

[0002] A torch is a device that burns waste gas as cleanly as possible. Common types include the straight-cylinder type, which is used for natural gas torches, coke oven gas torches, etc. There are also inverted cone types, which are used for torches that use water-coal slurry as raw materials to produce methanol and synthetic ammonia. There are also torches with smoke suppression functions.

[0003] The flare with smoke suppression function has smoke suppression steam pipes both inside and outside, and is mainly used in petrochemical and oil refining enterprises. The smoke suppression steam pipe is mainly composed of a steam ring pipe and multiple groups of steam branch pipes. The steam ring pipe is sleeved on the outside of the flare main pipe, and the steam branch pipe connected to the steam ring pipe extends into the interior of the flare main pipe. The steam branch pipe is connected to the steam ejector. Using the Venturi principle, the steam will induce the surrounding air to mix with the high-speed steam when it is ejected, and mix with the combustible gas from the inside of the flare main pipe to improve the combustion efficiency of the combustible gas, thereby reducing the generation of black smoke. When the high-speed steam drives the combustible gas to be ejected, the port pressure of the flare main pipe is relatively large, thereby causing the flame to be lifted, thereby reducing the impact of the high temperature of the flame on the flare main pipe.

[0004] When smoke suppression torches are used in petrochemical and oil refining enterprises, the content of combustible gas to be treated is not constant. When the amount of combustible gas treated is large, in order to improve combustion efficiency and reduce the generation of black smoke, the staff needs to manually adjust the steam injector to increase the steam injection amount. When the amount of combustible gas treated is small, in order to reduce steam waste, the workers will also manually reduce the steam injector. However, when the power of the steam injector decreases, the pressure of the ejected steam will also decrease accordingly, which will cause the height of the flame to be lifted to decrease. When the high-temperature flame is in contact with the flare pipe mouth for a long time, it will accelerate the damage of the flare main pipe. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a smoke elimination type torch head to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a smoke-eliminating flare head, comprising a flare main pipe, a flare branch pipe is arranged on the top of the flare main pipe, and a first control valve is installed on the side of the flare branch pipe, a steam ring pipe is installed on the outside of the flare branch pipe, a steam branch pipe is arranged on the top of the steam ring pipe, and a second control valve is installed on the side of the steam branch pipe.

[0007] By adopting the above technical scheme, by setting up multiple groups of flare branch pipes and multiple groups of steam branch pipes to work together, the multiple groups of flare branch pipes can be selectively opened according to the content of combustible gas. When the combustible gas content is low, the required amount of steam will also be reduced accordingly. By selecting to open one or two groups of flare branch pipes and the corresponding steam branch pipes, more precise control can ensure that the pressure of each group of flare branch pipes and steam branch pipes will not decrease. In the prior art, when the amount of combustible gas is reduced, the steam content also needs to be reduced, and the pressure of the steam content will also decrease, thereby weakening the ability of high-pressure steam to support the flame. The flare branch pipes and steam branches are freely opened and closed by the first control valve and the second control valve, so that the combustible gas of each group of flame branch pipes can be fully mixed with the steam, and a higher injection pressure can be maintained, so that the height of the high-pressure steam supporting the flame will not be reduced, reducing the damage of the high-temperature flame to the flare pipe mouth.

[0008] The utility model is further configured that the torch branch pipes are provided with multiple groups, and the multiple groups of torch branch pipes are evenly distributed on the top of the torch main pipe, and the sides of the torch branch pipes are all installed with first control valves.

[0009] By adopting the above technical solution, the output of the combustible gas content can be more precisely controlled by setting up multiple groups of torch branch pipes.

[0010] The utility model is further configured that the steam branch pipes are provided with multiple groups, and the multiple groups of steam branch pipes are evenly distributed on the top of the steam ring pipe, and the sides of the steam branch pipes are installed with second control valves.

[0011] By adopting the above technical solution, the output of steam content can be more finely controlled by setting up multiple groups of steam branch pipes, thereby maintaining the steam pressure in each group of flare branch pipes.

[0012] The utility model is further configured that the plurality of groups of flare branch pipes and steam branch pipes have the same number, and each group of steam branch pipes extends through and into the interior of the flare branch pipes.

[0013] By adopting the above technical solution and extending the steam branch pipe into the interior of the flare branch pipe, the steam, air and combustible gas can be fully mixed to improve the combustion efficiency.

[0014] The utility model is further configured that high temperature resistant fillers are installed on the tops of the multiple groups of torch branch pipes, and the high temperature resistant fillers are made of quartz sand, clay, and dolomite raw materials.

[0015] By adopting the above technical solution and arranging high temperature resistant fillers, the high temperature resistance of the flare branch pipe and the pipe mouth can be improved, and the service life of the flare branch pipe can be increased.

[0016] The utility model is further configured that a wind shield is installed outside the high temperature resistant filler, and the wind shield can block the interference of external factors on the flame.

[0017] By adopting the above technical solution and providing a wind shield, the interference of external wind on the flame can be reduced.

[0018] The utility model is further configured that a plurality of groups of ever-burning lights are installed outside the wind shield, and the plurality of groups of ever-burning lights correspond to the positions of the plurality of torches.

[0019] By adopting the above technical solution and setting a plurality of groups of ever-burning lamps, each group of torches can be selectively ignited.

[0020] The utility model is further configured that a steam interface is provided on the top of the steam ring pipe, and the steam ring pipe is connected to a steam ejector.

[0021] By adopting the above technical solution and providing a steam interface, the steam ring pipe can be connected to the steam emitter.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model sets a plurality of groups of torch branch pipes and a plurality of groups of steam branch pipes to cooperate with each other, so that the plurality of groups of torch branch pipes can be selectively opened according to the content of combustible gas. When the content of combustible gas is low, the required amount of steam will be reduced accordingly. By selecting to open one or two groups of torch branch pipes and the corresponding steam branch pipes, more precise control can ensure that the pressure of each group of torch branch pipes and steam branch pipes will not be reduced. In the prior art, when the amount of combustible gas is reduced, the steam content also needs to be reduced, and the pressure of the steam content will also decrease, thereby weakening the ability of high-pressure steam to support the flame. The torch branch pipes and the steam branch pipes are freely opened and closed by the first control valve and the second control valve, so that the combustible gas of each group of flame branch pipes can be fully mixed with the steam, and a relatively high injection pressure can be maintained, so that the height of the high-pressure steam supporting the flame will not be reduced, thereby reducing the damage of the high-temperature flame to the torch pipe mouth.

[0024] The utility model can better improve the high temperature resistance of the torch branch pipe mouth by arranging a high temperature resistant filler to wrap the pipe mouth of the torch branch pipe, thereby increasing the service life of the torch. A plurality of groups of torch branch pipes are arranged, and the plurality of groups of torch branch pipes are selectively opened, that is, the plurality of groups of torch branch pipes can be used alternately. When one group of torch branch pipes has been working for a long time, the other torch branch pipes can be replaced, so that the high-temperature torch branch pipe can be cooled and the service life of the torch can be further extended. There are large gaps between the plurality of groups of torch branch pipes, so that the torch branch pipes can dissipate heat better. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] A smoke-eliminating torch head, such as Figure 1-4 As shown, it includes a flare main pipe 1, a flare branch pipe 2 is arranged on the top of the flare main pipe 1, and a first control valve 3 is installed on the side of the flare branch pipe 2, a steam ring pipe 4 is installed outside the flare branch pipe 2, and a steam branch pipe 5 is arranged on the top of the steam ring pipe 4, and a second control valve 6 is installed on the side of the steam branch pipe 5. By arranging multiple groups of flare branch pipes 2 to work in coordination with multiple groups of steam branch pipes 5, multiple groups of flare branch pipes 2 can be selectively opened according to the content of combustible gas. When the content of combustible gas is low, the required amount of steam will also be reduced accordingly. By selecting to open one or two groups of flare branch pipes 2 and the corresponding steam branch pipes 5, more precise control can ensure that the pressure of each group of flare branch pipes 2 and steam branch pipes 5 will not decrease, so that the height of the high-pressure steam to support the flame will not decrease, reducing the damage of the high-temperature flame to the flare pipe mouth.

[0033] See also Figure 3 There are multiple groups of flare branch pipes 2, and the multiple groups of flare branch pipes 2 are evenly distributed on the top of the flare main pipe 1, and the sides of the flare branch pipes 2 are installed with first control valves 3. By setting multiple groups of flare branch pipes 2, the output of the combustible gas content can be more finely controlled.

[0034] See also Figure 3There are multiple groups of steam branch pipes 5, and the multiple groups of steam branch pipes 5 are evenly distributed on the top of the steam ring pipe 4, and a second control valve 6 is installed on the side of the steam branch pipe 5. By setting multiple groups of steam branch pipes 5, the output of the steam content can be more finely controlled, thereby maintaining the steam pressure in each group of flare branch pipes 2.

[0035] See also Figure 3 The number of the multiple groups of flare branch pipes 2 and the steam branch pipes 5 is the same, and each group of steam branch pipes 5 extends into the interior of the flare branch pipes 2. By extending the steam branch pipes 5 into the interior of the flare branch pipes 2, the steam, air and combustible gas can be fully mixed to improve the combustion efficiency.

[0036] See also Figure 2 A high temperature resistant filler 8 is installed on the top of multiple groups of torch branch pipes 2. The high temperature resistant filler 8 is made of quartz sand, clay, and dolomite. By setting the high temperature resistant filler 8, the high temperature resistance of the torch branch pipe 2 and the pipe mouth can be improved, and the service life of the torch branch pipe 2 can be improved.

[0037] See also Figure 2 A wind shield 9 is installed outside the high temperature resistant filler 8, and the wind shield 9 can block the interference of external factors on the flame. By setting the wind shield 9, the interference of external wind on the flame can be reduced.

[0038] See also Figure 2 A plurality of groups of ever-burning lamps 10 are installed outside the wind shield 9, and the positions of the plurality of groups of ever-burning lamps 10 correspond to the positions of the plurality of groups of torch branch pipes 2. By setting the plurality of groups of ever-burning lamps 10, each group of torch branch pipes 2 can be selectively ignited.

[0039] See also Figure 4 A steam interface 7 is provided at the top of the steam ring pipe 4, and the steam interface 7 is connected to a steam injector. By providing the steam interface 7, the steam ring pipe 4 can be connected to the steam injector.

[0040] The working principle of the utility model is as follows: according to the different contents of combustible gas, the flare branch pipes 2 and the steam ring pipe 4 are selectively started. For example, when the combustible gas content requires opening the three groups of flare branch pipes 2 and the steam ring pipe 4, the first control valve 3 and the second control valve 6 of the three groups of flare branch pipes 2 and the steam ring pipe 4 are opened, and the combustible gas enters the three groups of flare branch pipes 2 through the flare main pipe 1, and the high-pressure gas generated by the steam ejector enters the steam ring pipe 4 through the steam interface 7, and then enters the corresponding flare branch pipes 2 through the corresponding three groups of steam branch pipes 5. The high-pressure steam-induced air and the combustible gas are mixed and still maintain a relatively high pressure, and then the ever-burning lamp 10 is used to ignite the combustible gas.

[0041] When the content of the combustible gas changes, the number of the flare branch pipes 2 and the steam ring pipe 4 can be selectively opened according to the content of the combustible gas.

[0042] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
