Description

[Technical field]

[0001] The present invention relates to a pressure wave generating device for removing deposits by using pressure waves. [Background technology]

[0002] In incineration facilities for general waste and industrial waste, and in wood-based biomass power plants, combustion ash mainly adheres to the inside of the furnace, the inner wall surface of the exhaust passage, and the tube walls and radiator plates of heat exchangers such as boilers installed in the incineration facilities. Accumulation of adhesions such as combustion ash leads to a decrease in the efficiency of the combustion furnace. Therefore, in incineration facilities, adhesions are periodically removed from the furnace and exhaust passage. Non-patent document 1 describes a device that uses pressure waves to remove such deposits. The device ignites the combustion gas filled in a pressure vessel and instantly releases the rapid expansion pressure caused by the combustion to introduce a pressure wave from an injection nozzle into the inside of the target equipment, and the introduced pressure wave blows away the deposits, reducing their accumulation.

The pressure wave generator according to this embodiment includes a pressure vessel 10 filled with combustible gas, an injection nozzle 20 that injects pressure waves into the interior of a target facility such as an incinerator or boiler, and a wall fixing part 30 that is attached to a wall opening 2 provided in a wall 1 of the target facility. If the wall 1 of the target facility has a manhole, this manhole can be used as the wall opening 2. An ignition unit 10x and a gas inlet port 10y are provided at the bottom of the pressure vessel 10. The combustible gas to be filled into the pressure vessel 10 is injected from the gas inlet port 10y. The combustible gas is, for example, a mixed gas of methane and oxygen.

[0021] A pressure vessel flange portion 11 is provided on the discharge port 10a side of the pressure vessel 10. An injection nozzle flange portion 21 is provided on the injection nozzle 20 on the introduction port 20a side. The wall surface fixing portion 30 has a wall surface side mounting portion 31 connected to the wall portion 1, a pressure vessel side mounting portion 32 connected to the pressure vessel flange portion 11, and a pipe portion 33 connecting the wall surface side mounting portion 31 and the pressure vessel side mounting portion 32. The pressure vessel 10 is connected to the wall surface fixing portion 30 by fastening the pressure vessel flange portion 11 to the pressure vessel side mounting portion 32 using fastening members 40. The pressure vessel flange portion 11 and the injection nozzle flange portion 21 are connected by an opening and closing member 50. The opening / closing member 50 is disposed on the end face of the pressure vessel flange portion 11, and the fastening member 40 is disposed on the end face of the pressure vessel flange portion 11 located on the outer periphery of the opening / closing member 50. In this embodiment, a clamp lever 51 is shown as the opening / closing member 50, but a bolt may also be used. It is preferable to provide four opening / closing members 50 at equal intervals as shown in the figure.

[0022] As shown in Fig. 1(a), the thin film 60 is inserted between the pressure vessel flange 11 and the injection nozzle flange 21 through a slit 12 formed in the pressure vessel flange 11. For example, a stainless steel film can be used for the thin film 60. The thin film 60 is preferably a cartridge type that can be used once or multiple times.

[0023] A method for attaching the thin film 60 will be described with reference to FIG. 3(a) and 3(b) show the clamp lever 51 in an open state. As shown in FIG. 3(a), with the clamp lever 51 loosened (open), a gap is formed between the pressure vessel flange portion 11 and the injection nozzle flange portion 21. In this state, as shown in FIG. 3(b), the thin film 60 is inserted between the pressure vessel flange portion 11 and the injection nozzle flange portion 21 through the slit 12. After inserting the thin film 60, the clamp lever 51 is tightened (closed) as shown in Figure 3(c), thereby tightly fastening the pressure vessel flange portion 11 and the injection nozzle flange portion 21 with the thin film 60 sandwiched between them. By fastening the pressure vessel flange portion 11 and the injection nozzle flange portion 21 to be in close contact with each other, the discharge port 10 a of the pressure vessel 10 and the inlet 20 a of the injection nozzle 20 are closed by the thin film 60 . The membrane 60 is ruptured by igniting the combustible gases within the pressure vessel 10, causing the rupture to form an opening. When the thin film 60 is destroyed, the generated pressure wave is introduced into the target equipment, and the adhering matter can be removed by the introduced pressure wave. After the pressure waves have been generated, the membrane 60 is replaced. The thin film 60 can be removed by loosening the clamp lever 51 from the state shown in FIG. 3(c) to form a gap between the pressure vessel flange portion 11 and the injection nozzle flange portion 21.

[0024] In this way, by attaching the wall fixing part 30 to the wall 1 of the target equipment, attaching the pressure vessel 10 to the wall fixing part 30, and moving the injection nozzle 20 open and closed relative to the pressure vessel 10 to replace the thin film 60, the impact force when the pressure wave is generated is received by the wall fixing part 30, and only the impact force when the thin film 60 is broken is applied to the injection nozzle 20, so that only the impact force applied to the injection nozzle 20 is applied to the opening and closing member 50, and the opening and closing member 50 for clamping the thin film 60 is not easily subjected to the impact force when the pressure wave is generated. When the pressure vessel 10 is filled with combustible gas, the pressure inside the pressure vessel 10 is applied to the thin film 60. The opening and closing member 50 only needs to be able to maintain the sealing function of the thin film 60 against the pressure inside the pressure vessel 10. When ignited inside the pressure vessel 10, the combustible gas burns and pressure waves are generated. The pressure waves interfere with each other inside the pressure vessel 10, and the power of the waves increases as they overlap. The thin film 60 is destroyed when it can no longer withstand the pressure waves. Therefore, the maximum force applied to the opening and closing member 50 is the impact force when the thin film 60 is destroyed. The thin film 60 forms an opening for the injection nozzle 20 when broken, and the rigidity of the thin film 60 is set to be much lower than that of the wall surface of the pressure vessel 10, making the thin film 60 more susceptible to breakage. Even after the thin film 60 is broken, a pressure wave that increases instantaneously is generated, but the opening / closing member 50 does not need to withstand the impact force after the thin film 60 is broken. In this way, the impact force applied to the opening / closing member 50 is much smaller than that applied to the pressure vessel 10. Therefore, the opening / closing member 50 can be simplified, the thin film 60 can be easily replaced, and since the pressure vessel 10 can be replaced relative to the wall surface fixing part 30, the pressure vessel 10 can also be easily replaced.

[0025] Figures 4 and 5 show a pressure wave generator according to a second embodiment of the present invention, with Figure 4 being a cross-sectional view of the main parts of the pressure wave generator corresponding to Figure 2, and Figure 5 being an enlarged cross-sectional view of the circled part in Figure 4. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in addition to the first embodiment, an elastic member 70 that applies a biasing force to the opening and closing operation of the opening and closing member 50 is provided, and a coil spring 71 is used as the elastic member 70. The coil spring 71 is disposed between the pressure vessel flange portion 11 and the injection nozzle flange portion 21, and biases the pressure vessel flange portion 11 and the injection nozzle flange portion 21 in a direction separating them. In this way, by providing the elastic member 70, the pressure vessel flange portion 11 and the injection nozzle flange portion 21 can be securely fastened to each other, and when the clamp lever 51 is loosened, a gap can be reliably created between the pressure vessel flange portion 11 and the injection nozzle flange portion 21, making it easy to attach and detach the thin film 60.

[0026] Figures 6 and 7 show a pressure wave generator according to a third embodiment of the present invention, with Figure 6 being a cross-sectional view of the main parts of the pressure wave generator corresponding to Figure 2, and Figure 7 being an enlarged cross-sectional view of the circled part in Figure 6. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in addition to the first embodiment, an elastic member 70 that applies a biasing force to the opening and closing operation of the opening and closing member 50 is provided, and a disc spring 72 is used as the elastic member 70. The disc spring 72 is disposed between the pressure vessel flange portion 11 and the opening / closing member 50, and biases the pressure vessel flange portion 11 and the opening / closing member 50 in a direction separating them. In this way, by providing the elastic member 70, it is possible to reliably fasten the pressure vessel flange portion 11 and the injection nozzle flange portion 21. Although the clamp lever 51 has been described as the opening and closing member 50, a toggle mechanism or a hydraulic mechanism may also be used as the opening and closing member 50. By using a toggle mechanism or a hydraulic mechanism, a pressure wave generator with high durability can be obtained.

[0027] Figures 8 to 11 show a pressure wave generator according to a fourth embodiment of the present invention, with Figure 8 being a perspective view of the main parts of the pressure wave generator, Figure 9 being a front view of the pressure wave generator, Figure 10 being a sectional view of the main parts of the pressure wave generator, and Figure 11 being an enlarged sectional view of the circled part in Figure 10. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in the injection nozzle 20 of the first embodiment, the injection port 20b is formed at an angle to the inlet 20a of the injection nozzle 20, and the pressure vessel flange portion 11 is formed with an arc-shaped elongated hole 13 that can change the mounting angle of the pressure vessel flange portion 11 relative to the fastening member 40. In this way, by forming the arc-shaped long hole 13, the mounting angle of the pressure vessel flange portion 11 can be changed, and since the injection port 20b is formed at an angle relative to the inlet 20a, the injection direction of the injection port 20b can be changed. By changing the jet direction of the jet port 20b of the jet nozzle 20, the direction of the pressure wave inside the target equipment can be changed, and the deposits can be effectively removed.

[0028] Figures 12 to 14 show a pressure wave generator according to a fifth embodiment of the present invention, with Figure 12 being a perspective view of the main parts of the pressure wave generator, Figure 13 being a cross-sectional view of the main parts of the pressure wave generator, and Figure 14 being an enlarged cross-sectional view of the circled part in Figure 13. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in the injection nozzle 20 of the first embodiment, the injection port 20b is formed at an angle to the inlet 20a of the injection nozzle 20, and the pressure vessel flange portion 11 can be fastened to the wall surface fixing portion 30 by tightening the fastening member 40 from the outer peripheral surface of the pressure vessel flange portion 11, and the injection direction of the injection port 20b can be changed by changing the tightening position of the fastening member 40 on the outer peripheral surface of the pressure vessel flange portion 11. By changing the jet direction of the jet port 20b of the jet nozzle 20, the direction of the pressure wave inside the target equipment can be changed, and the deposits can be effectively removed.

[0029] Figures 15 to 17 show a pressure wave generator according to a sixth embodiment of the present invention, with Figure 15 being a perspective view of the main parts of the pressure wave generator, Figure 16 being a cross-sectional view of the main parts of the pressure wave generator, and Figure 17 being an enlarged cross-sectional view of the circled part in Figure 16. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in the injection nozzle 20 of the first embodiment, the injection port 20b is formed at an angle to the inlet 20a of the injection nozzle 20, and by providing rollers 41 on the outer peripheral surface of the pressure vessel flange portion 11, the mounting angle of the pressure vessel flange portion 11 with respect to the wall surface fixing portion 30 can be changed, and by changing the tightening position of the fastening member 40 on the outer peripheral surface of the pressure vessel flange portion 11, the injection direction of the injection port 20b can be changed. By changing the jet direction of the jet port 20b of the jet nozzle 20, the direction of the pressure wave inside the target equipment can be changed, and the deposits can be effectively removed. Furthermore, in this embodiment, in addition to the first embodiment, a dustproof film 81 is provided inside the wall surface fixing part 30, which separates the target equipment side from the pressure vessel flange part 11 side. The dust-proof film 81 has its outer periphery fixed between the wall surface side mounting portion 31 and the wall portion 1, and an opening through which the spray nozzle 20 can be inserted is formed in the center of the dust-proof film 81, and a tubular portion 81a is formed that can be extended from the opening and positioned along the outer periphery of the spray nozzle 20, and is positioned in the tube portion 33. In this way, by providing the dustproof film 81, it is possible to prevent dust from entering between the pressure vessel flange part 11 and the jet nozzle flange part 21 from inside the target equipment, and to maintain the tight fastening function between the pressure vessel flange part 11 and the jet nozzle flange part 21. Such a dustproof film 81 can also be applied to the second to fifth embodiments.

[0030] In the fourth to sixth embodiments of the present invention, it is preferable that the nozzle length of the jet nozzle 20 can be changed. The nozzle length can be changed by providing a mechanism for changing the length of the jet nozzle 20 itself, or by providing a plurality of jet nozzles 20 with different nozzle lengths or angles of the jet orifice 20b in advance and replacing them. In this way, by being able to change the nozzle length and the angle of the injection port 20b, it is possible to pinpoint the deposits that are firmly attached to the heat exchanger or the like.

[0031] FIG. 18 is an enlarged cross-sectional view showing a claw portion suitable for the fourth to sixth embodiments of the present invention. When the mounting angle of the pressure vessel flange portion 11 relative to the wall surface fixing portion 30 can be changed as in the fourth to sixth embodiments of the present invention, it is preferable to provide multiple claw portions 43 that are U-shaped when viewed from the side. The claw portion 43 sandwiches the wall surface side mounting portion 31 and the pressure vessel flange portion 11 and is fixed to at least one of the wall surface side mounting portion 31 and the pressure vessel flange portion 11 by a fastening member 43a. By providing such a plurality of claw portions 43, it is possible to prevent the pressure vessel 10 from falling off the wall surface fixing portion 30, and it is possible to allow the pressure vessel flange portion 11 to rotate smoothly relative to the wall surface side mounting portion 31.

[0032] Figures 19 to 21 show a pressure wave generator according to a seventh embodiment of the present invention, with Figure 19 being a perspective view of the main parts of the pressure wave generator, Figure 20 being a cross-sectional view of the main parts of the pressure wave generator, and Figure 21 being an enlarged cross-sectional view of the circled part in Figure 20. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in addition to the first embodiment, an elastic sheet 82 is provided inside the wall surface fixing part 30, which separates the target equipment side from the pressure vessel flange part 11 side. The elastic sheet 82 has its outer periphery fixed between the pressure vessel side mounting portion 32 and the pressure vessel flange portion 11 by the fastening member 40, and an opening through which the injection nozzle 20 can be inserted is formed in the center of the elastic sheet 82, and the elastic sheet 82 is placed on the pipe portion 33. It is also preferable to provide the fastening member 40 with a ring spacer 42. By providing the ring spacer 42, localized load on the elastic sheet 82 can be prevented. In this way, by providing the elastic sheet 82, it is possible to prevent the influence of pressure waves between the pressure vessel flange portion 11 and the injection nozzle flange portion 21, and to maintain the tight fastening function between the pressure vessel flange portion 11 and the injection nozzle flange portion 21. Note that such an elastic sheet 82 can also be applied to the second to sixth embodiments. Furthermore, by attaching the elastic sheet 82 with the fastening members 40, the elastic sheet 82 can be attached when the pressure vessel 10 is installed. Incidentally, when the metal flanges are in close contact with each other, shock waves that travel through the material in a short time tend to pass through as is. Therefore, by sandwiching the elastic sheet 82, the impedance effect can be used to reduce the amount of shock waves that pass through. Therefore, the elastic sheet 82 can reduce the impact force on the wall surface fixing part 30, and damage to the fireproof material used in the wall part 1 can be reduced.

[0033] Figures 22 to 24 show a pressure wave generator according to an eighth embodiment of the present invention, with Figure 22 being a perspective view of the main parts of the pressure wave generator, Figure 23 being a cross-sectional view of the main parts of the pressure wave generator, and Figure 24 being an enlarged cross-sectional view of the circled part in Figure 23. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in addition to the first embodiment, the pressure vessel flange portion 11 and the wall surface fixing portion 30 are attached via a vibration absorbing member 90 , and a coil spring 91 is used as the vibration absorbing member 90 . The coil spring 91 is disposed, via a bearing sleeve 91a, between the pressure vessel side mounting portion 32 and the pressure vessel flange portion 11, and between the pressure vessel flange portion 11 and the fastening member 40, and biases the pressure vessel side mounting portion 32 and the pressure vessel flange portion 11 in the direction of separating them, and also biases the pressure vessel flange portion 11 and the fastening member 40 in the direction of separating them. In this way, by attaching the pressure vessel flange portion 11 and the wall surface fixing portion 30 via the vibration absorbing member 90, it is possible to reduce the impact on the wall surface fixing portion 30 when a pressure wave is generated. Also, by using the coil spring 91 as the vibration absorbing member 90, it is possible to ensure the amount of displacement for absorbing vibration. Note that such a coil spring 91 as the vibration absorbing member 90 can also be applied to the second to seventh embodiments. After the thin film 60 is broken, a reaction force due to the propagation of the pressure wave is applied to the pressure vessel 10. This reaction force acts on the pressure vessel 10 in a direction away from the wall 1, but the vibration absorbing member 90 can dissipate this force. Therefore, it is possible to make it difficult for a large load to be transmitted to the fireproof material used in the wall 1.

[0034] Figures 25 to 27 show a pressure wave generator according to a ninth embodiment of the present invention, with Figure 25 being a perspective view of the main parts of the pressure wave generator, Figure 26 being a cross-sectional view of the main parts of the pressure wave generator, and Figure 27 being an enlarged cross-sectional view of the circled part in Figure 26. Note that the same members as in the first embodiment are given the same reference numerals and their explanation will be omitted. In this embodiment, in addition to the first embodiment, the pressure vessel flange portion 11 and the wall surface fixing portion 30 are attached via a vibration absorbing member 90 , and a disc spring 92 is used as the vibration absorbing member 90 . The disc spring 92 is disposed between the pressure vessel side mounting portion 32 and the pressure vessel flange portion 11, and biases the pressure vessel side mounting portion 32 and the pressure vessel flange portion 11 in a direction separating them. In this way, by attaching the pressure vessel flange portion 11 and the wall fixing portion 30 via the vibration absorbing member 90, it is possible to reduce the impact on the wall fixing portion 30 when a pressure wave is generated. Also, by using the disc spring 92 as the vibration absorbing member 90, it is possible to increase the elastic force and reduce deformation due to the weight of the pressure wave generator itself. Note that such disc spring 92 as the vibration absorbing member 90 can also be applied to the second to eighth embodiments.

[0035] FIG. 28 shows a pressure wave generator according to a tenth embodiment of the present invention. Fig. 28(a) is a perspective view of the main part of the pressure wave generator, and Fig. 28(b) and Fig. 28(c) are cross-sectional views of the main part of the pressure wave generator. Note that the same members as those in the first embodiment are given the same reference numerals and their explanations will be omitted. In this embodiment, the clamp lever 51 in the first embodiment is changed to a cam lever 52. The pressure vessel flange portion 11 and the injection nozzle flange portion 21 are fastened together by a cam lever 52, and the operating lever 52a of the cam lever 52 is placed on the flange surface of the pressure vessel flange portion 11 on the sealed vessel side. The pressure vessel flange portion 11 is fastened to the injection nozzle flange portion 21 by tightening the cam lever 52. FIG. 28(b) shows that the cam lever 52 is in a loosened (open) state, forming a gap between the pressure vessel flange portion 11 and the injection nozzle flange portion 21. In FIG. 28(c), the cam lever 52 is tightened (closed), whereby the pressure vessel flange portion 11 and the injection nozzle flange portion 21 are tightly fastened together with the thin film 60 sandwiched therebetween. In this manner, the cam lever 52 can be used to connect the pressure vessel flange portion 11 and the injection nozzle flange portion 21 .

[0036] As described above, according to this embodiment, the wall fixing part 30 is attached to the wall 1 of the target equipment, the pressure vessel 10 is attached to the wall fixing part 30, and the injection nozzle 20 is moved to open and close relative to the pressure vessel 10 to replace the thin film 60, so that the impact when a pressure wave is generated is received by the wall fixing part 30 and the injection nozzle 20 is only subjected to the impact when the thin film 60 is broken, and therefore only the impact applied to the injection nozzle 20 is applied to the opening and closing member 50, and the opening and closing member 50 for sandwiching the thin film 60 is unlikely to be subjected to the impact when a pressure wave is generated. Therefore, by simplifying the opening and closing member 50, the thin film 60 can be easily replaced, and by replacing the pressure vessel 10 relative to the wall fixing part 30, the pressure vessel 10 can also be easily replaced. Furthermore, according to this embodiment, the pressure vessel side mounting portion 32 can be closed and the wall surface fixing portion 30 can be left connected to the wall portion 1 by the wall surface side mounting portion 31, and when performing the work of removing adhesions, the pressure vessel 10 can be attached by connecting the pressure vessel side mounting portion 32 and the pressure vessel flange portion 11. [Industrial Applicability]
