Description

Technical Field

[0001] The present disclosure relates to the technical field of thermoacoustic instability, and in particular to a heat source device for a Rijke tube and a use method thereof. Background Art

[0002] Combustion instability is the result of the full coupling of unsteady heat release and sound waves in the combustion system. The famous Rayleigh criterion points out that when the unsteady heat release in the combustion system is in phase with the sound wave, the heat energy is converted into sound energy. In a finite short time, the sound energy in the system increases sharply. If the sound energy increased by the system's thermal-acoustic coupling is greater than the dissipation of the sound in the system, combustion instability will occur. On the contrary, when the unsteady heat release and the sound wave are in opposite phases, the sound energy will be converted into heat energy and the combustion instability will be suppressed. The Rijke tube is a device for studying thermoacoustic oscillations. Usually, the Rijke tube is a vertically placed hollow tube with both ends open. A heating element is placed inside. When the heating element is fixed to the lower half of the tube, the resonant frequency of the pipe is excited and a resonant sound is emitted.

[0003] In the thermoacoustic experiment of Rijke tube, choosing the right heat source form is the key factor to realize the oscillation phenomenon and the key to expand the control range of heating parameters. Therefore, in the design process of the heat source section, it is necessary to select a heating element with a moderate length and capable of not melting under the required power under the premise of fixing the inner diameter of the heat source section, and arrange and fix it reasonably in the heat source section to ensure that the heating element will neither short-circuit itself nor contact the inner wall of the metal heat source section. However, the current experimental research on Rijke tubes is usually based on heating elements of single heating wires or spring-shaped heating wires. The single heating wire or spring-shaped heating wire is wound on a cross-shaped or two-shaped insulating sheet, and then the insulating sheet is fixed in the tube for heating. However, this heating method of heating wires usually has insufficient space for arrangement in the tube, the arrangement is too compact and the fixation is unstable, which easily leads to short circuit or contact of the heating element itself with the tube wall. In addition, when connecting the power supply, wiring is difficult, and the insulating sheet is easy to burn and deform in a long-term high temperature environment.

[0004] Therefore, how to solve the problem in the prior art that the heating elements have insufficient space in the tube, are arranged too compactly and are unstable in fixation, resulting in short circuit or contact between the heating elements and the tube wall, is one of the important issues to be solved in this field.

[0039] Combustion instability is the result of the full coupling of unsteady heat release and sound waves in the combustion system. The famous Rayleigh criterion points out that when the unsteady heat release in the combustion system is in phase with the sound wave, the heat energy is converted into sound energy. In a finite short time, the sound energy in the system increases sharply. If the sound energy increased by the system's thermal-acoustic coupling is greater than the dissipation of the sound in the system, combustion instability will occur. On the contrary, when the unsteady heat release and the sound wave are in opposite phases, the sound energy will be converted into heat energy and the combustion instability will be suppressed. The Rijke tube is a device for studying thermoacoustic oscillations. Usually, the Rijke tube is a vertically placed hollow tube with both ends open. A heating element is placed inside. When the heating element is fixed to the lower half of the tube, the resonant frequency of the pipe is excited and a resonant sound is emitted.

[0040] In the thermoacoustic experiment of Rijke tube, choosing the right heat source form is the key factor to realize the oscillation phenomenon and the key to expand the control range of heating parameters. Therefore, in the design process of the heat source section, it is necessary to select a heating element with a moderate length and capable of not melting under the required power under the premise of fixing the inner diameter of the heat source section, and arrange and fix it reasonably in the heat source section to ensure that the heating element will neither short-circuit itself nor contact the inner wall of the metal heat source section. However, the current experimental research on Rijke tubes is usually based on heating elements of single heating wires or spring-shaped heating wires. The single heating wire or spring-shaped heating wire is wound on a cross-shaped or two-shaped insulating sheet, and then the insulating sheet is fixed in the tube for heating. However, this heating method of heating wires usually has insufficient space for arrangement in the tube, the arrangement is too compact and the fixation is unstable, which easily leads to short circuit or contact of the heating element itself with the tube wall. In addition, when connecting the power supply, wiring is difficult, and the insulating sheet is easy to burn and deform in a long-term high temperature environment.

[0041] In response to the above problems, the exemplary embodiments of the present disclosure provide a heat source device and a method of use for a Rijke tube to solve the problem that the heating elements have insufficient space in the tube, are arranged too compactly, and are unstable in fixation, resulting in short circuits or contact between the heating elements and the tube wall.

[0042] A heat source device for a Rijke tube according to an embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0043] Figure 1 is a schematic cross-sectional structural diagram illustrating a heat source device for a Rijke tube according to an embodiment of the present disclosure, Figure 2 Schematic diagram of the heat source device for Rijke tube according to the embodiment of the present disclosure. Figure 1 - Figure 2 As shown, the heat source device for the Rijke tube includes: a heating support 1, a first insulating member 2, a connecting member 3, a heating element and a second insulating member 4. The connecting member 3 is provided with a first groove 31 for placing the heating support 1 and a second groove 32 for placing the first insulating member 2. The heating support 1 is located in the first groove 31. The heating support 1 is used to fix the heating element. The heating element is evenly distributed on the heating support 1; the first insulating member 2 is located in the second groove 32. The first insulating member 2 is used to isolate the contact between the charged heating element and the Rijke tube; a first through hole 33 for placing the second insulating member 4 is also provided on the side wall of the connecting member 3, and a second through hole 21 for placing the second insulating member 4 is provided on the side wall of the first insulating member 2. The first through hole 33 is connected to the second through hole 21, and the second insulating member 4 is inserted along the first through hole 33 and the second through hole 21 in sequence until it contacts the inner side wall of the first insulating member 2.

[0044] In practical applications, such as Figure 1As shown, the connector 3 is provided with a first groove 31 for placing the heating support 1 and a second groove 32 for placing the first insulating member 2. It should be understood that the above-mentioned connector 3 can be a flange pipe, a connecting pipe with a thread, and other connectors 3. Here, the flange pipe is taken as an example. The heating support 1 is located in the first groove 31, and the first insulating member 2 is located in the second groove 32. By opening the first groove 31 and the second groove 32 on the connector 3, the heating support 1 and the first insulating member 2 are fixed, and the problem of unstable fixing of the heating element is effectively avoided. Based on this, the heating support 1 is used to fix the heating element. It can be understood that the above-mentioned heating element can be an electric heating element such as an electric heating wire, an electric heating belt, etc., which will not be described in detail here. The present disclosure takes a spring-shaped electric heating wire as an example. Compared with a single electric heating wire, the spring-shaped electric heating wire can more effectively utilize the space inside the tube, and its length can be freely adjusted, which is convenient for installation and wiring. The spring-shaped electric heating wire is interspersed and arranged between the holes on the heating support 1, making full use of the internal space of the heat source section. The heating element is fixed on the heating support 1 to ensure that the heating element is fixed and stable. At the same time, the heating elements are evenly distributed on the heating support 1, which ensures that the heating elements are reasonably distributed and avoids the problem of too compact arrangement. On this basis, the first insulating member 2 is used to isolate the contact between the charged heating element and the Rijke tube. The side wall of the connecting member 3 is also provided with a first through hole 33 for placing the second insulating member 4. The side wall of the first insulating member 2 is provided with a second through hole 21 for placing the second insulating member 4. The first through hole 33 is connected to the second through hole 21. The second insulating member 4 is inserted along the first through hole 33 and the second through hole 21 in sequence until it contacts the inner wall of the first insulating member 2. The first insulating member 2 is used to isolate the charged heating element from the Rijke tube to avoid contact between the heating element and the Rijke tube, thereby ensuring the safety of the above-mentioned heat source device for the Rijke tube. At the same time, the wire connected to the heating element avoids contact between the wire body and the Rijke tube through the second insulating member, making the wiring process more convenient and safe. The use of the heat source device for Rijke tubes effectively solves the problems in the prior art of insufficient arrangement space for heating elements in the tube, too compact arrangement and unstable fixation, resulting in short circuit or contact between the heating elements and the tube wall.

[0045] For example, Figure 3 Schematic diagram of the structure of the heat source device for Rijke tube heating support 1 according to the embodiment of the present disclosure. Figure 3As shown, the heating support 1 is a circular heating support 1. It can be understood that the above circular heating support 1 is embedded in the connecting member to ensure the stability of the heating support 1. The heating support 1 is provided with a plurality of third through holes 11 and a fourth through hole 12. It should be understood that the provision of a plurality of third through holes 11 ensures that the heating element can be stably inserted in each third through hole 11, thereby ensuring the stability of the heating element on the heating support 1. At the same time, it can also avoid the heating elements from contacting each other during arrangement and after thermoacoustic oscillation, thereby preventing local melting. Each third through hole 11 is evenly distributed along the circumferential direction of the fourth through hole 12. In order to ensure that the fourth through hole 12 is connected to the upstream and downstream Rijke tubes, it should be understood that the above circumferential direction is along the circumferential direction of the connecting member.

[0046] For example, Figure 3 As shown, a plurality of first bosses 13 are provided on the outer wall of the heating support 1. It should be understood that the heating support 1 is made of insulating and high-temperature resistant material, mainly processed using mica board, and a plurality of third grooves are also provided on the connecting member, and each first boss 13 is adapted to each third groove. It should be understood that the first boss 13 is adapted to the third groove to ensure that during the installation process, the heating support 1 will not rotate due to the pulling of the heating element, thereby ensuring the stability of the installation and fixation, and at the same time, facilitating the disassembly between the heating support 1 and the connecting member while ensuring the stability between the heating support 1 and the connecting member.

[0047] Exemplarily, the radial dimension of the first groove is greater than the radial dimension of the second groove. In a specific application, the first groove is used to place the heating support member, and the second groove is used to place the first insulating member. Since the first insulating member needs to separate the heating element from the Rijke tube, when ensuring the use of the heat source device for the Rijke tube, it is necessary to ensure that the second insulating member cannot slide out of the connecting member. Therefore, it is necessary to ensure that the radial dimension of the first groove is greater than the radial dimension of the second groove.

[0048] like Figure 3 As shown, the radius of the pitch circle formed by each third through hole is smaller than the radius of the Rijke tube. It can be understood that the above-mentioned pitch circle is a circle formed by connecting the geometric centers of each third through hole 11 as points. When the radius of the pitch circle formed by each third through hole 11 is smaller than the radius of the Rijke tube, it can be ensured that the heating element can be coiled on the heating support 1, and at the same time, it can be ensured that the heating element will not contact the inner wall of the Rijke tube, thereby ensuring that the heating element works in a safe environment.

[0049] Figure 4 is a schematic diagram further illustrating the structure of the first insulating member of the heat source device for the Rijke tube according to the embodiment of the present disclosure, such as Figure 4As shown, it should be understood that the first insulating member and the connecting member are both hollow structures, which ensures the circulation of air in the tube. At the same time, the second boss 22 of the first insulating member close to the end surface of the heating support effectively avoids the problem of the first insulating member falling off after being placed in the connecting member.

[0050] Figure 5 is a schematic diagram of a heat source device connector structure for a Rijke tube according to an embodiment of the present disclosure, as shown in Figure 5 As shown, in actual application, both ends of the connector are metal pipes with flanges, and the bolt holes and pin holes on the flanges are used to connect with the upstream and downstream Rijke pipes 5. The heating support and the first insulating member are respectively embedded in the interior thereof through processing, and a first through hole 33 for placing the second insulating member is also provided on the side wall of the connector, and a third groove 34 for connecting each boss is provided on the connecting end surface at one end.

[0051] Figure 6 is a schematic diagram further illustrating the structure of the second insulating member of the heat source device for the Rijke tube according to the embodiment of the present disclosure, such as Figure 6 As shown, the length of the second insulating member 4 is greater than the wall thickness of the Rijke tube. In actual applications, the second insulating member 4 is made of ceramic material. The second insulating member 4 is inserted along the first through hole and the second through hole in sequence until it contacts the inner wall of the first insulating member. The connecting wire connecting the heating element needs to be inserted into the second insulating member. The second insulating member 4 avoids contact between the wire body and the Rijke tube, making the wiring process more convenient and safer.

[0052] The present disclosure also provides a method for using a heat source device for a Rijke tube. Figure 7 is a flow chart further illustrating a method for using a heat source device for a Rijke tube according to an embodiment of the present disclosure.
