Description

Technical Field

[0001] This invention belongs to the field of burner technology, and in particular relates to an automated flame temperature detection device. Background Technology

[0002] In industrial applications, such as power plants, oil refineries, or boiler systems, flame temperature needs to be monitored to ensure safety and efficiency. Excessive temperature can damage equipment or lead to excessive emissions, while insufficient temperature may result in incomplete combustion, wasting fuel or producing harmful substances.

[0003] Existing technologies have many limitations in detecting burner flame temperature: contact sensors can only measure the temperature at a single point during the temperature detection process and cannot reflect the longitudinal temperature gradient of the flame, which affects the accuracy of the study of its combustion characteristics and reaction mechanism, and thus has a negative impact on the efficient, energy-saving, safe and clean operation of industrial equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an automated flame temperature detection device to solve the above-mentioned problems in the existing technology, which is that the flame temperature detection of burners can only measure the temperature at a single point and cannot reflect the longitudinal temperature gradient of the flame.

[0005] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0006] An automated flame temperature detection device includes a burner body and a flame temperature detection mechanism disposed on the side of the burner body;

[0007] The burner body is used to generate a flame, and a glass cover is fitted over the outside of the burner body. The outer surface of the glass cover is provided with multiple detection holes.

[0008] The flame temperature detection mechanism is located on the side of the burner body. The flame temperature detection mechanism includes a thermocouple, an X-axis translation mechanism, and a Y-axis translation mechanism. The thermocouple is equipped with a detection probe, which is used to detect the flame temperature. The thermocouple is located at the output end of the X-axis translation mechanism, and the X-axis translation mechanism is located at the output end of the Y-axis translation mechanism and is placed perpendicular to the Y-axis translation mechanism.

[0009] The thermocouple is also equipped with an oscilloscope.

[0010] Furthermore, the plurality of detection holes are spaced apart along the axial direction of the glass cover.

[0011] Furthermore, the Y-axis translation mechanism includes a Y-axis guide rail, a Y-axis moving stage slidably disposed on the Y-axis guide rail, and a Y-axis driving mechanism.

The X-axis driving mechanism is used to drive the X-axis moving stage to move on the X-axis guide rail, and the thermocouple is disposed on the X-axis moving stage.

[0013] The Y-guide is perpendicular to the X-guide.

[0014] Furthermore, it also includes a control system, which is equipped with a multi-channel controller for controlling the operation of the X-axis translation mechanism and the Y-axis translation mechanism.

[0015] Furthermore, the control system is also used to receive temperature data from an oscilloscope.

[0016] Furthermore, a support platform is provided at the bottom of the burner body, and the glass cover and the burner body are both placed on the support platform.

[0017] Furthermore, the outer surface of the glass cover is provided with an adjustable sealing structure, which includes multiple sealing elements and a screw mechanism located at both ends of the sealing elements, with each sealing element corresponding to a multiple detection hole;

[0018] The sealing element includes a sealing hemisphere and two baffles located at the left end of the sealing hemisphere. The rear end of the sealing hemisphere is tightly placed inside the detection hole, and the sealing hemisphere has an insertion hole that communicates with the detection hole.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0046] In industrial applications, such as power plants, oil refineries, or boiler systems, flame temperature needs to be monitored to ensure safety and efficiency. Excessive temperature can damage equipment or lead to excessive emissions, while insufficient temperature may result in incomplete combustion, wasting fuel or producing harmful substances.

[0047] Existing technologies for burner flame temperature detection have several limitations: contact sensors can only measure temperature at a single point and cannot reflect the longitudinal temperature gradient of the flame, thus affecting the accuracy of research on its combustion characteristics and reaction mechanisms, and consequently negatively impacting the efficient, energy-saving, safe, and clean operation of industrial equipment; furthermore, the temperature measurement process relies on manual adjustment, and the lack of a unified standard for temperature interval settings leads to temporal differences in the collected data. During data processing, the X-axis (time) position needs to be manually adjusted to ensure that the extracted temperature data corresponds to a specific X-axis position. Therefore, manual temperature measurement methods adversely affect the standardization and accuracy of subsequent temperature data processing.

[0048] like Figure 1 As shown, an automated flame temperature detection device includes a burner body 1 and a flame temperature detection mechanism 3 disposed on the side of the burner body 1.

[0049] The burner body 1 is used to generate a flame. The burner body 1 is fitted with a glass cover 2. The outer surface of the glass cover 2 is provided with multiple detection holes 20.

[0050] The flame temperature detection mechanism 3 is located on the side of the burner body 1. The flame temperature detection mechanism 3 includes a thermocouple 31, an X-axis translation mechanism 32 and a Y-axis translation mechanism 33. The thermocouple 31 is provided with a detection probe 34, which is used to detect the flame temperature. The thermocouple 31 is located at the output end of the X-axis translation mechanism 32, and the X-axis translation mechanism 32 is located at the output end of the Y-axis translation mechanism 33 and is placed perpendicular to the Y-axis translation mechanism 33.

[0051] Thermocouple 31 is also equipped with an oscilloscope 4;

[0052] The working principle of this automated flame temperature detection device is as follows:

[0053] S1. Drive the X-axis translation mechanism 32 to a certain height through the Y-axis translation mechanism 33, so that the detection probe 34 on the thermocouple 31 is level with the height of the detection hole 20 at the position to be detected outside the glass cover 2.

[0054] S2. Drive the detection probe 34 horizontally to the detection hole 20 at the position to be detected by the X-axis translation mechanism 32, and detect the temperature of the flame generated by the burner body 1 at that height position.

[0055] S3. Drive the detection probe 34 out of the detection hole 20 through the X-axis translation mechanism 32;

[0056] S4. Repeat steps S1-S3 to obtain flame temperature data at different heights.

[0057] This automated flame temperature detection device can also be configured with a control system to achieve automated detection;

[0058] This automated flame temperature detection device can measure temperatures at multiple points, thus reflecting the longitudinal temperature gradient of the flame. The measured temperature distribution allows for optimization of the combustion dynamics model. Furthermore, the temperature data enables optimization of combustion efficiency, achieving refined control of the combustion process, improving energy efficiency, reducing fuel costs, and ensuring safe equipment operation while preventing localized overheating and thermal fatigue. In addition, this detection device also contributes to environmental protection, primarily because it can analyze the temperature peak location based on the temperature distribution, optimize combustion strategies, and ultimately control pollutant emissions.

[0059] This automated flame temperature detection device provides support for the research and development of clean combustion technology and has irreplaceable value in the fields of energy, aviation, and chemical industry.

[0060] like Figures 1 to 7 As shown, in some embodiments of the present invention, the Y-axis translation mechanism 33 includes a Y-axis guide rail 331, a Y-axis moving stage slidably disposed on the Y-axis guide rail 331, and a Y-axis driving mechanism. The Y-axis driving mechanism is used to drive the Y-axis moving stage to move on the Y-axis guide rail 331, and the X-axis translation mechanism 32 is disposed on the Y-axis moving stage.

[0061] X-axis translation mechanism 32 includes X-axis guide rail 321, X-axis moving stage slidably disposed on X-axis guide rail 321, and X-axis drive mechanism. X-axis drive mechanism is used to drive X-axis moving stage to move on X-axis guide rail 321. Thermocouple 31 is disposed on X-axis moving stage.

[0062] Y-guide rail 331 is perpendicular to X-guide rail 321;

[0063] Specifically, the Y-axis drive mechanism and the X-axis drive mechanism can adopt a ball screw drive mechanism, a belt drive mechanism, a gear and rack drive mechanism, a common cylinder or a hydraulic rod to realize the displacement of the detection probe 34 in the horizontal direction and the displacement in the vertical direction.

[0064] Specifically, if a ball screw transmission mechanism is used, it generally consists of a stepper motor, a lead screw (screw), and a lead screw slider (nut). The lead screw, through the interaction of the helical threads, converts the rotational motion of the input shaft into the precise linear motion of the nut. The lead screw slider can drive the corresponding X-axis or Y-axis moving stage. That is, in the Y-axis translation mechanism 33, its Y-axis drive mechanism drives the Y-axis moving stage to move on the Y-axis guide rail 331, thereby causing the Y-axis moving stage to drive the X-axis translation mechanism 32 mounted on it to move; while in the X-axis translation mechanism 32, the X-axis drive mechanism drives the X-axis moving stage to move on the X-axis guide rail 321, thereby causing the X-axis moving stage to drive the thermocouple 31 mounted on it to move; thus, the translation of the thermocouple 31 in the vertical direction (i.e., Y-axis) and the horizontal direction (i.e., X-axis) can be completed.

[0065] Similarly, if a regular cylinder or hydraulic rod is used, the Y-axis moving stage or the X-axis moving stage can be directly driven to move on the Y-axis guide rail 331 or the X-axis guide rail 321, respectively.

[0066] like Figures 1 to 7 As shown, in some embodiments of the present invention, a plurality of detection holes 20 are distributed at intervals along the axial direction of the glass cover 2, and the distance between two adjacent detection holes 20 may be the same or different.

[0067] The spacing between two adjacent detection holes 20 can be set according to actual detection requirements.

[0068] like Figures 1 to 7 As shown, in some embodiments of the present invention, the number of detection holes 20 is not less than 6; setting multiple detection holes 20 can improve the ability to finely control the combustion process; multiple measured data can be obtained through multiple detection holes 20, which can be used for numerical model verification and reduce combustion model error; and can also realize multi-dimensional analysis of the combustion process.

[0069] like Figure 1 As shown, in some embodiments of the present invention, the automatic flame temperature detection device further includes a control system 8, which is equipped with a multi-channel controller 9. The multi-channel controller 9 is used to control the operation of the X-axis translation mechanism 32 and the Y-axis translation mechanism 33.

[0070] The control system 8 is also used to receive temperature data from the oscilloscope 4;

[0071] With the control system 8 in place, this automatic flame temperature detection device can achieve automated detection. Specifically, the working principle of this automatic flame temperature detection device is as follows:

[0072] S1. The control system 8 sends a control signal to the multiplexer 9. The multiplexer 9 receives and executes the control signal and sends a signal to the Y-axis translation mechanism 33. By controlling the Y-axis translation mechanism 33, the X-axis translation mechanism 32 is driven to rise to a certain height, so that the detection probe 34 on the thermocouple 31 is flush with the height of the detection hole 20 at the position to be detected outside the glass cover 2.

[0073] S2. The multi-channel controller 9 sends a signal to the X-axis translation mechanism 32, and drives the detection probe 34 to move horizontally to the detection hole 20 at the position to be detected by controlling the X-axis translation mechanism 32. The temperature of the flame generated by the burner body 1 at this height position is detected, and the temperature data is transmitted to the control system 8 through the oscilloscope 4.

[0074] S3. The multiplexer 9 sends a signal to the X-axis translation mechanism 32, and drives the detection probe 34 to move out of the detection hole 20 by controlling the X-axis translation mechanism 32.

[0075] S4. Repeat steps S1-S3 to obtain flame temperature data at different heights;

[0076] In this invention, a control system 8 and a multi-channel controller 9 work together. The control system 8 sends control signals to the multi-channel controller 9 to precisely regulate the coordinated actions of the Y-axis translation mechanism 33 and the X-axis translation mechanism 32. Specifically, the standard working time for the Y-axis translation mechanism 33 to complete the vertical displacement between adjacent detection holes 20 is marked as t1, and the standard working time for the X-axis translation mechanism 32 to extend into the detection hole 20 and perform flame temperature detection is marked as t2. The control system 8 performs dynamic calibration on multiple sets of t1 and t2 to ensure that the temperature data acquisition sequence of each detection hole 20 is consistent, thereby realizing the automated control of the entire process.

[0077] This automated control system, through fixed timing control, ensures a strict correspondence between temperature data and the time axis of the oscilloscope, eliminating coordinate offset errors caused by manual operation; automated timing management effectively avoids process fluctuations that may be caused by manual intervention, ensuring the standardization and repeatability of temperature curve analysis; this standardized temperature data acquisition timing provides a clear timing reference benchmark for data difference analysis.

[0078] In this invention, to address the problem of temperature timing discrepancies that occur during manual temperature measurement, which necessitates manual adjustment of the X-axis (time) position in the temperature curve, an automated control system is employed. This system ensures that the temperature data extracted from the oscilloscope 4 more accurately corresponds to the specific X-axis (time) position, thus avoiding errors caused by human intervention.

[0079] like Figures 1 to 7 As shown, in some embodiments of the present invention, the burner body 1 is provided with a support platform at its bottom, and the glass cover 2 and the burner body 1 are both placed on the support platform.

[0080] like Figures 1 to 7 As shown, in some embodiments of the present invention, the outer surface of the glass cover 2 is provided with an adjusting sealing structure 5. The adjusting sealing structure 5 includes a plurality of sealing elements 6 and a screw mechanism 7 provided at both ends of the sealing elements 6. The plurality of sealing elements 6 correspond one-to-one with the plurality of detection holes 20.

[0081] That is, multiple seals 6 are used for sealing the detection hole 20 when it is not being detected;

[0082] The sealing element 6 includes a sealing hemisphere 61 and two baffles 62 located at the left end of the sealing hemisphere 61. The rear end of the sealing hemisphere 61 is tightly placed inside the detection hole 20. The sealing hemisphere 61 has an insertion hole 610 that communicates with the detection hole 20.

[0083] Specifically, the rear end of the sealing hemisphere 61 is fixedly installed in the detection hole 20, and due to the setting of the insertion hole 610, the detection probe 34 on the thermocouple 31 can be easily inserted; two baffles 62 are provided at the front end of the sealing hemisphere 61 to seal the opening (i.e. the insertion hole 610) at the left end of the sealing hemisphere 61.

[0084] The baffle member 62 includes a sealing baffle 621 and a connecting rod 622 disposed on the side of the sealing baffle 621. The sealing baffle 621 is disposed at the left end of the sealing hemisphere 61. By providing the sealing baffle 621, the opening (i.e., the insertion hole 610) of the sealing hemisphere 61 is sealed. Specifically, in the initial state, the two sealing baffles 621 on the baffle member 62 are close to each other, and their close sides are in tight contact, thereby completing the sealing of the opening (i.e., the insertion hole 610) of the sealing hemisphere 61. The connecting rod 622 is used to remove the sealing baffle 621 from the opening (i.e., the insertion hole 610) to facilitate the insertion of the detection probe 34.

[0085] The lead screw mechanism 7 includes a drive motor 701, a lead screw 702, and a lead screw slider 703. A mounting housing 704 is fitted around the lead screw mechanism 7. The lead screw 702 is rotatably housed within the mounting housing 704. The drive motor 701 is located on the top of the mounting housing 704 and is used to drive the lead screw 702 to rotate. The lead screw mechanism 7 operates smoothly and with high precision. Combined with the control system 8, it enables control of the lead screw mechanism 7, thereby achieving precise control of the lifting and lowering of the lead screw slider 703.

[0086] The lead screw slider 703 is mounted on the outside of the lead screw 702;

[0087] The right end of the lead screw slider 703 is provided with a limiting post 705. The end of the limiting post 705 away from the lead screw slider 703 is slidably disposed at the rear end inside the mounting housing 704. Specifically, by providing the limiting post 705, which is fixedly disposed outside the limiting post 705, and the end of the limiting post 705 away from the lead screw slider 703 is slidably installed at the rear end inside the mounting housing 704, this arrangement ensures that the lead screw slider 703 does not deviate during the lifting and lowering process, thereby improving the stability of its lifting and lowering process.

[0088] The lead screw slider 703 is provided with a mounting block 71, and a miniature cylinder 72 is provided on the side of the mounting block 71. The miniature cylinder 72 is used to push the adapter combination rod 622 to move.

[0089] The adapter rod 622 is also provided with a limiting member 623 on the outside, which is located on the mounting housing 704. The limiting member 623 provides support for the adapter rod 622 and also ensures the smoothness of the movement of the adapter rod 622 under the push of the micro cylinder 72.

[0090] In addition, a connecting spring 628 is fitted on the outside of the first adapter rod 625. One end of the connecting spring 628 is connected to the limiting member 623, and the other end of the connecting spring 628 is connected to the sealing baffle 621.

[0091] Based on this, by providing an adjustable sealing structure 5 on the outer surface of the glass cover 2, the principle during actual testing is as follows:

[0092] S1. Drive the X-axis translation mechanism 32 to a certain height through the Y-axis translation mechanism 33, so that the detection probe 34 on the thermocouple 31 is level with the height of the detection hole 20 at the position to be detected outside the glass cover 2.

[0093] S2. The X-axis translation mechanism 32 drives the detection probe 34 to move horizontally to the detection hole 20 area of ​​the position to be detected; the screw mechanism 7 raises the micro cylinder 72 to the designated position and pushes the adapter rod 622 through the micro cylinder 72, thereby moving the two sealing baffles 621 on the baffle 62 away from each other, so that the insertion hole 610 of the sealing hemisphere 61 is exposed. The detection probe 34 passes through the insertion hole 610 and the detection hole 20 in sequence to detect the temperature of the flame generated by the burner body 1 at this height position.

[0094] S3. Drive the detection probe 34 out of the detection hole 20 through the X-axis translation mechanism 32, and then raise the micro cylinder 72 to the designated position through the lead screw mechanism 7, so that the output end of the micro cylinder 72 is disengaged from the adapter combination rod 622, and the adapter combination rod 622 is reset under the action of the connecting spring 628.

[0095] S4. Repeat steps S1-S3 to obtain flame temperature data at different heights;

[0096] During this process, the two sealing baffles 621 outside the detection hole 20 at the detection point are opened, exposing the insertion hole 610 of the sealing hemisphere 61 for easy detection. The detection holes 20 at other locations are closed by the two sealing baffles 621, thereby reducing the problem of reduced detection accuracy caused by gas disturbance during the detection process. In the non-detection state, the two sealing baffles 621 outside all detection holes 20 are in contact to ensure the stability of the detection environment, thereby maintaining the stability of combustion conditions, reducing temperature fluctuations caused by environmental fluctuations, improving data repeatability, and avoiding airflow disturbances.

[0097] like Figures 1 to 7 As shown, in some embodiments of the present invention, the multi-channel controller 9 is also used to control the operation of the drive motor 701 and the micro cylinder 72; thereby enabling automatic detection of flames at different heights.

[0098] In this invention, to facilitate subsequent data processing, the standard working time for the Y-axis translation mechanism 33 to complete the vertical displacement between adjacent detection holes 20 is marked as t1, and the standard working time for the X-axis translation mechanism 32 to extend into the detection hole 20 and perform flame temperature detection is marked as t2. The control system 8 performs dynamic calibration on multiple sets of t1 and t2 to ensure that the temperature data acquisition sequence of each detection hole 20 is consistent, thereby realizing the automated control of the entire process.

[0099] Based on this, in this invention, the multi-channel controller 9 can receive control commands from the control system 8 to control the operation of the drive motor 701 and the micro cylinder 72, so that the process of the micro cylinder 72 controlling the exposure of the through hole 610 of the sealing hemisphere 61 and the process of the screw mechanism 7 raising the micro cylinder 72 to the designated position do not affect t1 and t2.

[0100] Based on this, the multi-channel controller 9 can receive control commands from the control system 8 and synchronously regulate the operation of the drive motor 701 and the miniature cylinder 72. The key technical points are as follows: the miniature cylinder 72 controls the opening and closing of the insertion hole 610 of the sealing hemisphere 61, and the screw mechanism 7 performs the vertical displacement positioning of the miniature cylinder 72; the above operation is independent of the t1 and t2 timing parameters, avoiding interference with the core temperature measurement process.

[0101] Specifically, in actual execution, the parallel operation design ensures time independence, meaning that the auxiliary actions of the micro cylinder 72 and the lead screw mechanism 7 are completely independent of the t1 and t2 time sequence control, eliminating the interference of equipment start-up and shutdown on data acquisition; the actions of each mechanism are carried out in an orderly manner, ensuring efficient coordination of the displacement of the detection probe 34, the opening and closing of the adjustment sealing structure 5, and the reset process, thereby improving the continuity of the process; based on this strict time isolation mechanism, the accuracy of the temperature data extracted by the oscilloscope 4 and the time axis mapping is improved, effectively avoiding time drift errors caused by manual operation;

[0102] Therefore, this setting can effectively optimize the full-cycle management of temperature data in industrial testing scenarios.

[0103] like Figures 1 to 7 As shown, in some embodiments of the present invention, a sealing gasket 624 is also provided on the rear side of the sealing baffle 621. The sealing gasket 624 is fixedly installed on the sealing baffle 621 to further enhance the sealing performance between the sealing baffle 621 and the sealing hemisphere 61.

[0104] like Figures 1 to 7 As shown, in some embodiments of the present invention, the adapter combination rod 622 includes a first adapter rod 625, a U-shaped adapter rod 626 and a second adapter rod 627. One end of the open end of the U-shaped adapter rod 626 is connected to the first adapter rod 625, and the other end of the open end of the U-shaped adapter rod 626 is connected to the second adapter rod 627.

[0105] Specifically, such as Figure 3As shown, the U-shaped adapter rod 626 includes a vertical rod and horizontal rods fixedly installed at both ends of the vertical rod. The vertical rod is perpendicular to the horizontal rod. Of the two horizontal rods, the upper horizontal rod is marked as horizontal rod 1# and the lower horizontal rod is marked as horizontal rod 2#. That is, the first adapter rod 625 is connected to horizontal rod 1# and is perpendicular to horizontal rod 1#, while the second adapter rod 627 is connected to horizontal rod 2# and is perpendicular to horizontal rod 2#. Thus, when the micro cylinder 72 pushes the second adapter rod 627, the sealing baffle 621 moves in the same direction as the second adapter rod 627.

[0106] The end of the first adapter rod 625 away from the U-shaped adapter rod 626 is connected to the sealing baffle 621;

[0107] The limiting member 623 is provided with a limiting sliding hole that cooperates with the first adapter rod 625; thus, it provides support for the first adapter rod 625 while ensuring the smooth movement of the first adapter rod 625.

[0108] The mounting housing 704 has a limiting sliding hole 2 that matches the closed end of the U-shaped adapter rod 626;

[0109] The mounting housing 704 is also provided with a limiting sliding hole three that cooperates with the second adapter rod 627; this setting provides support for the U-shaped adapter rod 626 and the second adapter rod 627 while ensuring the smooth movement of the U-shaped adapter rod 626 and the second adapter rod 627.

[0110] Furthermore, the first adapter rod 625 can also move on the mounting housing 704. That is, since the limiting member 623 is provided on the mounting housing 704, a through hole that mates with the first adapter rod 625 can be provided at the corresponding position of the mounting housing 704 (i.e., the side near the limiting member 623), thereby facilitating the movement of the first adapter rod 625. In addition, a notch can also be provided at the corresponding position of the mounting housing 704 (i.e., the side near the limiting member 623), so as not to affect the movement of the first adapter rod 625.

[0111] This invention provides an automated flame temperature detection device that can measure the temperature at multiple points, thereby reflecting the longitudinal temperature gradient of the flame. By measuring the temperature distribution, the combustion dynamics model can be optimized, thus providing support for the research and development of clean combustion technology. It has irreplaceable value in the fields of energy, aviation, and chemical industry.
