Description

Technical Field

[0001] This invention belongs to the field of combustion technology, and in particular relates to a semi-coke tail gas burner, specifically a semi-coke tail gas burner with adjustable blade angle. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Semi-coke tail gas is a byproduct of the coal chemical industry. It consists of combustible gases such as hydrogen, methane, and carbon monoxide. Direct emission of semi-coke not only causes environmental pollution but also wastes resources.

[0004] Currently, methods for treating semi-coke tail gas have become increasingly mature. Generating electricity by burning semi-coke tail gas can solve the emission problem and generate economic benefits. However, the quality of semi-coke tail gas is affected by many factors. Raw coal quality, production processes, and the production environment can all cause variations in the calorific value of the tail gas, leading to significant differences in combustion between different batches. Furthermore, in practical applications, due to factors such as the arrangement of the intake pipe and the burner installation position, the intake pressure drop often varies at different circumferential positions of the same set of blades, resulting in uneven airflow distribution. Existing semi-coke tail gas burners cannot independently adjust the blade angle to address these differences, affecting combustion efficiency. Summary of the Invention

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0020] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0021] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0022] In practical applications of semi-coke tail gas, due to factors such as the arrangement of the intake pipe and the installation position of the semi-coke tail gas burner, the intake pressure drop at different circumferential positions of the same set of blades often varies, resulting in uneven airflow distribution. Existing semi-coke tail gas burners cannot independently adjust the blade angle to address this difference, thus affecting combustion efficiency.

[0023] like Figures 1 to 4 As shown, where, Figure 1 The schematic diagram illustrates the structure of a semi-coke tail gas burner 100 according to an embodiment of the present invention. The semi-coke tail gas burner 100 includes a central air duct 4, a semi-coke tail gas duct 3, an inner secondary air duct 2, an outer secondary air duct 1, and a blade adjustment assembly. The semi-coke tail gas duct 3 is sleeved on the outside of the central air duct 4; the inner secondary air duct 2 is sleeved on the outside of the semi-coke tail gas duct 3; and the outer secondary air duct 1 is sleeved on the outside of the inner secondary air duct 2. The central air duct 4, the semi-coke tail gas duct 3, and the inner secondary air duct 1 are connected. Both the cylinder body 2 and the outer secondary air cylinder body 1 are provided with insertion holes 102; blade adjustment assemblies are respectively provided between the central air cylinder body 4 and the semi-coke tail gas cylinder body 3, between the semi-coke tail gas cylinder body 3 and the inner secondary air cylinder body 2, and between the outer secondary air cylinder body 1 and the inner secondary air cylinder body 2. Each blade adjustment assembly includes a blade body 5 and a pusher 6. The pusher 6 is connected to the blade body 5. The blade body 5 is provided with a rotating pin 51 that cooperates with the insertion hole 102 so that the blade body 5 can be rotatably connected to the insertion hole 102.

[0024] Both the external secondary air duct 1 and the internal secondary air duct 2 here have lateral air intake. The function of the internal secondary air is to supplement the oxygen required in the early to middle stages of combustion and to work with the primary air to form a stable ignition and combustion environment. The function of the external secondary air is to provide the oxygen required in the later stages of combustion and to enhance the mixing of semi-coke exhaust gas with air, thus promoting the complete combustion of the semi-coke exhaust gas.

[0025] It should be noted that the semi-coke tail gas burner 100 here also includes an ignition gun channel 8, which is located inside the central air duct body 4. The ignition gun channel 8 is only opened during boiler startup and ignition, and retracts into the central air duct body 4 during normal operation. The central air duct body 4 is a hollow cylindrical structure, which can be a cylindrical, rectangular, or elliptical structure. Combustion air can be introduced into the interior of the central air duct body 4, either axially or circumferentially. Figure 1 In the middle, the semi-coke tail gas burner 100 is also equipped with an air inlet pipe 7, which is connected to the central air duct body 4, and can introduce combustion air into the interior of the central air duct body 4 through the air inlet pipe 7.

[0026] Continue to refer to Figure 1As shown, a semi-coke exhaust gas cylinder 3 is fitted around the outside of the central air duct 4. The shape of the semi-coke exhaust gas cylinder 3 is the same as that of the central air duct 4, and the central air duct 4 is located within the space enclosed by the semi-coke exhaust gas cylinder 3. In this embodiment, the semi-coke exhaust gas cylinder 3 is also a cylindrical structure. It can be understood that the inner secondary air duct 2 and the outer secondary air duct 1 are also the same shape as the central air duct 4. The inner secondary air duct 2 and the outer secondary air duct 1 are hollow cylindrical structures, which can be cylindrical, rectangular, or elliptical. Preferably, the central air duct 4, the semi-coke exhaust gas cylinder 3, the inner secondary air duct 2, and the outer secondary air duct 1 are all cylindrical structures, which facilitates the assembly of the semi-coke exhaust gas burner 100 and the installation of the blade adjustment assembly.

[0027] Each blade adjustment assembly mentioned here includes a blade body 5 and a pusher 6. The pusher 6 is connected to the blade body 5. The blade body 5 is provided with a rotating pin 51 that cooperates with the insertion hole 102, so that the blade body 5 can be rotatably connected to the insertion hole 102. During the movement of the pusher 6, the blade body 5 can adjust its angle by rotating the rotating pin 51 within the insertion hole 102.

[0028] According to the semi-coke tail gas burner 100 of the present invention, blade adjustment assemblies are respectively provided between the central air duct body 4 and the semi-coke tail gas duct body 3, between the semi-coke tail gas duct body 3 and the inner secondary air duct body 2, and between the outer secondary air duct body 1 and the inner secondary air duct body 2. Each blade adjustment assembly includes a blade body 5 and a pusher 6. The pusher 6 is connected to the blade body 5. The blade body 5 is provided with a rotating pin 51 that cooperates with the insertion hole 102 so that the blade body 5 can be rotatably connected to the insertion hole 102. Thus, the angle of the blade body 5 connected to the pusher 6 of each blade adjustment assembly can be adjusted, thereby realizing independent adjustment of the angle of each blade body 5.

[0029] In some embodiments of the present invention, such as Figure 1As shown, the central air duct 4, the semi-coke exhaust gas duct 3, the inner secondary air duct 2, and the outer secondary air duct 1 are coaxially arranged. It should be noted that the coaxial arrangement of the central air duct 4, the semi-coke exhaust gas duct 3, the inner secondary air duct 2, and the outer secondary air duct 1 means that their centerlines coincide, thus forming annular spaces between the central air duct 4 and the semi-coke exhaust gas duct 3, between the semi-coke exhaust gas duct 3 and the inner secondary air duct 2, and between the inner secondary air duct 2 and the outer secondary air duct 1. Blade adjustment components are respectively located within these annular spaces. In other words, blade adjustment components are installed in the annular spaces formed between the central air duct 4 and the semi-coke exhaust gas duct 3, between the semi-coke exhaust gas duct 3 and the inner secondary air duct 2, and between the inner secondary air duct 2 and the outer secondary air duct 1.

[0030] The following is combined Figures 2 to 4 , Figure 2 for Figure 1 The diagram shows the blade adjustment assembly in operation. Figure 3 for Figure 1 The schematic diagram of the central air duct 4 shown is shown below. Figure 4 for Figure 2 The schematic diagram of the blade adjustment assembly shown is from a second-view perspective (the pusher 6, handheld component 62, central air duct 4, and semi-coke exhaust gas duct 3 are not shown). The structure of the blade adjustment assembly will be described in detail below.

[0031] In some embodiments of the present invention, the blade body 5 is further provided with a sliding pin 52, and the central air duct 4, the semi-coke exhaust gas duct 3, and the inner secondary air duct 2 are all provided with a sliding groove 101 that slides with the sliding pin 52, so that the blade body 5 can slide within the range defined by the sliding groove 101. It should be noted that each blade body 5 is provided with a sliding pin 52. Considering that there are multiple blade bodies 5 and that the blade bodies 5 are located in different spaces, for ease of description, the following is combined with... Figure 1 As shown, the blade body 5 is named differently depending on its installation location. When the blade body 5 is located between the inner secondary air duct 2 and the outer secondary air duct 1, it is called the outer secondary air blade 11. When the blade body 5 is located between the semi-coke exhaust gas duct 3 and the inner secondary air duct 2, it is called the inner secondary air blade 21. When the blade body 5 is located between the central air duct 4 and the semi-coke exhaust gas duct 3, it is called the central air blade 41.

[0032] Continue to refer to Figure 1 As shown, the outer secondary air blade 11, the inner secondary air blade 21, and the central air blade 41 have the same structure and can all be adopted. Figure 2 The structure in the text, below is... Figure 2 The blade body 5 in this example refers to the outer secondary air blade 11. There are two rotating pins 51, located above and below the blade body 5 respectively. Each rotating pin 51 is connected to the blade body 5. The upper rotating pin 51 engages with the insertion hole 102 on the outer secondary air duct 1, and the lower rotating pin 51 engages with the insertion hole 102 on the inner secondary air duct 2. The axes of the two rotating pins 51 are on the same straight line, allowing the blade body 5 to rotate around the rotating pins 51, thus adjusting the angle of the blade body 5. Here, "above" and "below" refer to the height direction of the semi-coke tail gas burner 100. Figure 1 and Figure 2 The ZZ direction in the middle.

[0033] It should be noted that the angle of the blade body 5 here can be represented by α, which can be characterized by the angle between the blade body 5 and the direction of the airflow. The direction of the airflow is as shown by the direction of the broad arrow in 1.

[0034] In some embodiments of the present invention, at least one of the groove 101 and the insertion hole 102 is a blind hole structure. The insertion hole 102 can be either a blind hole or a through hole. However, to achieve a sealing effect, the rotating pin 51 can be sealed to the insertion hole 102, for example, by using a sealing ring or sealant. Considering that the groove 101 needs to be a curved strip structure, it is set as a blind hole structure to reduce the probability of gas flowing out of the groove 101 and reduce the probability of gas leakage.

[0035] In some embodiments of the present invention, such as Figure 2 As shown, the blade body 5 has a plate-like structure. The center surfaces of the sliding pin 52 and the rotating pin 51 are located in the same plane as the center surface of the plate-like structure. Both the sliding pin 52 and the rotating pin 51 can be cylindrical pins, which are less prone to breakage. The cooperation between the sliding pin 52 and the groove 101 can play a guiding role, making the movement of the pusher 6 smoother during the control of the blade body 5's rotation.

[0036] In some embodiments of the present invention, such as Figure 4As shown, the blade body 5 is provided with a hinge seat 53. One end of the pusher 6 is connected to the blade body 5 through the hinge seat 53, and the other end of the pusher 6 is located outside the corresponding cylinder. The pusher 6 can be a rod-shaped structure, with one end connected to the hinge seat 53. The hinge seat 53 is located on the blade body 5, specifically on the surface of the blade body 5. It can be located at the edge of the surface of the blade body 5 or in the center area of ​​the surface. Figure 4 In the middle, the hinge seat 53 is located near the edge of the plate surface of the blade body 5, which can increase the lever arm of the hinge seat 53 relative to the rotating pin 51, making it easier to rotate the blade body 5 by the pusher 6.

[0037] Furthermore, the phrase "the other end of the pusher 6 is located outside the corresponding cylinder" means that the pusher 6 can extend along the XX direction, and the other end of the pusher 6 can be located outside the corresponding cylinder, where XX is the length direction of the semi-coke tail gas burner 100. For example, when the pusher 6 is located between the inner secondary air cylinder 2 and the outer secondary air cylinder 1, the other end of the pusher 6 is located outside the inner secondary air cylinder 2, and the other end of the pusher 6 is located outside the outer secondary air cylinder 1. This makes it convenient for the operator to pull the pusher 6 away from the outer secondary air cylinder 1, or to push the pusher 6 towards the outer secondary air cylinder 1, thereby adjusting the angle of the outer secondary air blades 11.

[0038] It is understandable that when the pusher 6 is located between the semi-coke exhaust gas cylinder 3 and the inner secondary air cylinder 2, the other end of the pusher 6 is located outside the inner secondary air cylinder 2, and the other end of the pusher 6 is located outside the semi-coke exhaust gas cylinder 3. This makes it convenient for the operator to pull the pusher 6 away from the inner secondary air cylinder 2, or to move it closer to the inner secondary air cylinder 2, thereby adjusting the angle of the inner secondary air blades 21.

[0039] It should be added that when the pusher 6 is located between the central air duct 4 and the semi-coke exhaust gas duct 3, the other end of the pusher 6 is located outside the central air duct 4 and outside the semi-coke exhaust gas duct 3, which makes it convenient for the operator to move away from the semi-coke exhaust gas duct 3 or to move closer to the semi-coke exhaust gas duct 3, thereby realizing the adjustment of the angle of the central air blade 41.

[0040] In some embodiments of the present invention, such as Figure 2As shown, the semi-coke tail gas burner 100 also includes a handheld component 62, which is connected to the other end of the pusher 6 and located outside the corresponding cylinder. The handheld component 62 can be a handle structure, located outside the corresponding cylinder, allowing the operator to easily control the pulling or pushing action of the pusher 6.

[0041] In some embodiments of the present invention, such as Figure 2 As shown, the pusher 6 is provided with scale lines 61, which are spaced apart along the length of the pusher 6. The scale lines 61 can be provided on the upper surface of the pusher 6 or on the side surface of the pusher 6. Specifically, the scale lines 61 can cover the entire upper surface of the pusher 6 or only a portion of the upper surface of the pusher 6. Figure 2 In the middle, the scale line 61 is set on part of the upper surface of the pusher 6, so as to facilitate the observation of the pushing distance of the pusher 6, and thus the rotation angle of the blade body 5 can be controlled by the scale line 61 of the pusher 6.

[0042] In some embodiments of the present invention, a panel is provided at one end of the semi-coke tail gas cylinder 3 near the blade body 5. The panel is provided with fuel injection holes 31. The shape of the fuel injection holes 31 is one of circular, rectangular or elliptical. The panel can be an outwardly protruding arc plate structure or an outwardly protruding zigzag plate structure. The fuel injection holes 31 are provided on the panel.

[0043] The number of fuel injection holes 31 is multiple, and these multiple fuel injection holes 31 can be spaced apart along the circumference of the panel, forming a circular ring structure. Alternatively, the multiple fuel injection holes 31 can also be configured as two or more circular ring structures, wherein the two circular ring structures are arranged radially spaced along the semi-coke exhaust gas cylinder 3, and the fuel injection holes 31 are all set at an angle to the length direction of the semi-coke exhaust gas burner 100, so that the semi-coke exhaust gas can be injected in different directions.

[0044] Continue to refer to Figure 1 As shown, in Figure 1 The broad arrows indicate the direction of gas flow in each channel. Except for the airflow inside the semi-coke exhaust gas cylinder 3, the airflow in the other channels is lateral. The airflow inside the semi-coke exhaust gas cylinder 3 is ejected outward from different fuel injection holes 31.

[0045] In some embodiments of the present invention, a plurality of blade adjustment assemblies are provided between the central air duct body 4 and the semi-coke exhaust gas duct body 3, and the plurality of blade adjustment assemblies are arranged at intervals along the circumference of the central air duct body 4, such as... Figure 3As shown, the central air duct body 4 is provided with multiple insertion holes 102, which are spaced apart along the circumference of the central air duct body 4. Correspondingly, the central air duct body 4 is provided with the same number of sliding grooves 101, each sliding groove 101 and the corresponding insertion hole 102 are provided, so that the blade body 5 of each blade adjustment assembly can be adjusted independently.

[0046] Similarly, multiple blade adjustment assemblies are also provided between the semi-coke tail gas cylinder 3 and the inner secondary air cylinder 2. The connection method and arrangement of each blade adjustment assembly are the same as or similar to those mentioned above, and will not be repeated here.

[0047] Correspondingly, multiple blade adjustment assemblies are also provided between the outer secondary air duct 1 and the inner secondary air duct 2. The connection method and arrangement structure of each blade adjustment assembly are the same as or similar to those mentioned above, and will not be repeated here.

[0048] Multiple blade bodies 5 are arranged between the central air duct 4 and the semi-coke exhaust gas duct 3. These blade bodies 5 are spaced apart along the circumference, and adjacent blade bodies 5 do not interfere with each other. When it is necessary to adjust the angle of a certain blade body 5, the angle of the blade body 5 can be adjusted by pulling the pusher 6 outward or pushing the pusher 6 inward using the handheld part 62 of the blade adjustment assembly. When the pusher 6 is pulled outward, the angle of the blade body 5 decreases; when the pusher 6 is pushed inward, the angle of the blade body 5 increases.

[0049] In the semi-coke tail gas burner 100 of the present invention, the pushing distance of the pushing member 6 corresponds to the rotation angle of the blade body 5. The pushing distance of the pushing member 6 can be determined by reading the scale line 61, thereby realizing the adjustment of the angle of the blade body 5. In this embodiment, the adjustment range of the rotation angle of the blade body 5 is designed to be 10° to 45°, covering the typical operating conditions required for the operation of the semi-coke tail gas burner 100.

[0050] Each blade body 5 here has a corresponding pusher 6 for control. In other words, each blade body 5 is set independently and is not linked to each other. This allows each blade body 5 on the same cylinder and the blade bodies 5 on different cylinders to be adjusted to different angles as needed, achieving true independent adjustment.

[0051] The independent adjustment design of the blade body 5 of the semi-coke tail gas burner 100 in this embodiment has significant engineering practical value. In actual operation, due to factors such as the arrangement of the air intake duct and bends, the intake pressure drop of the semi-coke tail gas burner 100 often varies at different circumferential positions. If a traditional synchronous adjustment mechanism is used, it is impossible to make targeted adjustments for this difference. However, in this embodiment, the operator can adjust the angle of the blade body 5 at the corresponding position according to the pressure drop at each position.

[0052] The following section will focus on the method for adjusting the angle of the blade body 5.

[0053] The first adjustment method is based on the calorific value of the fuel. The calorific value of the semi-coke tail gas often fluctuates with the upstream production process. When the calorific value of the semi-coke tail gas is too high, the operator can reduce the angle of the blade body 5, and if necessary, reduce the angle of the blade body 5 to the minimum, to delay the mixing speed of the semi-coke tail gas with air, reduce the probability of the formation of local high-temperature zones, and thus effectively reduce the formation of thermal nitrogen oxides. Conversely, when the calorific value of the semi-coke tail gas is too low, the operator can increase the angle of the blade body 5, and if necessary, increase the angle of the blade body 5 to the maximum, to enhance the intensity of the swirl, increase the high-temperature flue gas recirculation area, and increase the temperature level at the flame root, thereby stabilizing the combustion process and preventing flameout or flameout.

[0054] The second adjustment method is based on circumferential pressure distribution. In actual operation, due to factors such as the arrangement of the intake pipe and bends, the intake pressure drop of the semi-coke tail gas burner 100 often varies at different circumferential positions, resulting in uneven airflow distribution. In this embodiment, the operator can adjust the angle of the blade body 5 at each position according to the pressure drop. Specifically, for positions near the intake port with higher airflow pressure, the angle of the blade body 5 can be appropriately increased to increase the swirl intensity in that area; for positions far from the intake port with lower airflow pressure, the angle of the blade body 5 can be appropriately decreased to reduce flow resistance. This embodiment of the invention, through this circumferential differential adjustment, can effectively compensate for the airflow non-uniformity caused by the intake pipe structure, making the airflow distribution in each circumferential direction more uniform, thereby optimizing the combustion flow field and increasing combustion stability.

[0055] Furthermore, during the use of the semi-coke tail gas burner 100, the blade bodies 5 of different channels need to be coordinated in terms of angle. Specifically, under actual operating conditions, in order to better organize the airflow distribution and achieve staged air distribution combustion, the angle of the blade body 5 on the central air duct 4 is greater than or equal to the angle of the blade body 5 on the inner secondary air duct 2, and the angle of the blade body 5 on the inner secondary air duct 2 is greater than or equal to the angle of the blade body 5 on the outer secondary air duct 1.

[0056] Combination Figure 1As shown, more specifically, the angle of the central air blade 41 on the central air duct 4 is greater than or equal to the angle of the inner secondary air blade 21 on the inner secondary air duct 2, and the angle of the inner secondary air blade 21 on the inner secondary air duct 2 is greater than or equal to the angle of the outer secondary air blade 11 on the outer secondary air duct 1. This is because a larger angle of the central air blade 41 can form a stable central recirculation zone, thereby drawing high-temperature flue gas to the root of the flame and playing a role in stabilizing combustion. In addition, the angle of the inner secondary air blade 21 here is less than or equal to the angle of the central air blade 41, which can form a fuel-rich zone and suppress the generation of nitrogen oxides. The angle of the outer secondary air blade 11 here is less than or equal to the angle of the inner secondary air blade 21, which can enhance the rigidity of the flame and ensure the complete combustion of the semi-coke tail gas.

[0057] Specifically, the angles of the central wind vane 41, the inner secondary wind vane 21, and the outer secondary wind vane 11 are all within the range of 10° to 45°. For example, the angle of the central wind vane 41 is 25°, the angle of the inner secondary wind vane 21 is 20°, and the angle of the outer secondary wind vane 11 is 15°, or the angle of the central wind vane 41 is 20°, the angle of the inner secondary wind vane 21 is 18°, and the angle of the outer secondary wind vane 11 is 13°.

[0058] In summary, the embodiments of the present invention, by designing an independently adjustable blade body 5 and cooperating with the scale line 61 on the pusher 6, can quantitatively adjust the angle of the blade body 5, enabling operators to flexibly optimize the swirl intensity of each channel according to the changes in the calorific value and / or pressure distribution of the semi-coke tail gas, thereby significantly improving the combustion efficiency of the semi-coke tail gas burner 100, reducing pollutant emissions, and enhancing adaptability to different operating conditions.

[0059] The semi-coke tail gas burner 100 of the present invention achieves flexible and precise adjustment of the angle of the blade body 5 through the rotational engagement of the rotating pin 51 and the insertion hole 102, the sliding engagement of the sliding pin 52 and the sliding groove 101, and the pusher 6 hinged to the blade body 5. This results in a simple and reliable structure. Furthermore, the pusher 6 for each blade body 5 is independently configured, enabling differentiated angle adjustment for each blade body 5 within the same group. This design can independently compensate for pressure drop differences at different circumferential positions caused by factors such as the intake duct arrangement, resulting in a more uniform airflow distribution at each position and thus optimizing the combustion flow field.
