Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a low-frequency device used for the purpose of enhancing the efficiency of heat exchange, mass transfer, combustion, etc. by utilizing the resonance of low-frequency gas vibration, and removing dirt and soot. Particularly, it relates to a technology for downsizing and simplification of arrangement.

[0002]

[Prior art]

 Conventionally, low-frequency utilization devices have been used to oscillate air or gas such as generated gas that is the target of heat exchange at low frequency, resonate this with a resonance tube, and use this resonance phenomenon for the purpose of improving heat exchange efficiency. Are known. For example, as a low-frequency utilizing device for performing strong heat transfer with an object by a low-frequency stationary sound wave, a device as shown in FIGS. 10 (a) to 10 (c) has been proposed (Tokuhokuhei 4-501456). No. 5 (for (a) in the same figure) and Japanese Patent Publication No. 5-501457 (for (b) and (c)).

The device of FIG. 1A is of an opposed type, and two low-frequency sound wave generators 100, 100 generate low-frequency sound waves that are 180 ° out of phase, and each has a length corresponding to a quarter wavelength. The resonance tube 101 is a device that resonates sound waves so that the ends of the resonance tubes 101 and 101 become the abdomen. In this device, one common stationary sound wave of 1/2 wavelength type having the same frequency as each resonance frequency is generated. In the apparatus shown in FIG. 2B, a low-frequency sound wave is generated by the generator 100, and the sound wave is resonated so that the central portion of the resonance tube 102 having a length corresponding to ½ wavelength is the abdomen. Further, in the device (c), a resonance tuning box 104 is provided at a position facing the exit side of the 1/4 wavelength resonance tube 103, and resonance is performed at the exit of the resonance tube so that the maximum amplitude is obtained. In such a conventional device, the resonance tube is a straight tube or a bent tube having a gentle curve depending on the positional relationship with the object to be processed. By doing so, it is possible to reduce friction loss due to gas vibration in the resonance tube.

[0004]

[Problems to be solved by the device]

 However, even if a low frequency sound wave of 20 Hz is resonated with a length of 1/4 wavelength, the length of the resonance tube is 4.25 m, and in the case of the opposed type, the total length of the two resonance tubes is Since the resonance tube is a straight tube or a bent tube as in the conventional case, the low frequency device becomes extremely large. Such an increase in the size of the device has been a major drawback as compared with other devices having the same purpose such as heat exchange and removal of adhering substances. Therefore, the present invention solves the above-mentioned problems in the prior art, downsizes the resonance tube, and provides a low-frequency utilization device that is compact and has a small installation area by using the downsized resonance tube. Is an issue.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a device for low frequency use, wherein a low-frequency utilization device has a vibration source, first and second resonance tubes, and a container, and the vibration source is 180 ° A vibration generating part for generating low-frequency gas vibrations out of phase is provided, and the first resonance pipe and the second resonance pipe are respectively connected to one end side connecting part connected to the vibration generating part and the above-mentioned second resonance pipe. Gas vibration is transmitted, has a length of 1/4 of the wavelength, and is provided with a vibration transmission part formed in a coil shape and the other end side connection part to which the gas vibration is transmitted, and is integrally formed in the longitudinal direction. The container is provided with first and second connecting portions connected to the respective other end side connecting portions, and is arranged in parallel and close to the first resonance pipe and the second resonance pipe, In addition to the above, the device according to claim 2 is characterized in that the container has the first connection part and the The invention according to claim 3 is characterized in that it has a partition member for partitioning between the two connection parts, and the low-frequency utilization device has a vibration source, first to fourth resonance tubes, and a container, The vibration source includes a vibration generator that generates two sets of low-frequency gas vibrations that are 180 ° out of phase with each other, and the first resonance pipe and the second resonance pipe are respectively connected to the vibration generator. The one end side connection part to be connected, the vibration transmission part to which the gas vibration is transmitted and has a length of 1/4 of the wave length and which is formed in a coil shape, and the other end side connection part to which the gas vibration is transmitted are connected. The third resonance pipe and the fourth resonance pipe are formed in the same manner as the first resonance pipe and the second resonance pipe, respectively, and are arranged in parallel and close to each other. The container is installed in an inverted position by the operation of the above-mentioned vibration source in the connection part on the other end side. And a connection part that is connected to the other end side connection part so as to be separated from each other, and is disposed in proximity to the first to fourth resonance tubes. The invention of claim 4 is characterized in that, in addition to the features of the invention of claim 3, the container has a partition member for partitioning between the connection parts having the opposite phase. In addition to the features of the invention of claims 1 to 4, the vibration transmitting unit includes a curved inner cylinder arranged inside a curved outer cylinder, and a spiral between the outer cylinder and the inner cylinder. It is characterized in that it is formed in a coil shape by providing a partition.

[0006]

[Action]

 According to the invention of claim 1, the vibration transmitting portion of the resonance tube (hereinafter referred to as “pipe”) is formed in a coil shape. Here, “the pipe is formed in a coil shape” means that the pipe is wound in a plurality of stages and the stages are close to each other or are partitioned by a common partition. Since the pipeline is formed in a coil shape, the distance between both ends of the pipeline is significantly shorter than the pipeline length. As a result, the size of the resonance tube can be greatly reduced in obtaining the required conduit length. In this case, since the pipe is coiled, it is formed only by the bent portion, and the resonance pipe of the present invention has a larger friction resistance of the vibrating gas as compared with the conventional straight pipe or the bent pipe. . However, this increase in resistance is not so large, and for this, the roughness of the inner wall of the pipe is reduced to reduce the frictional resistance coefficient, and the capacity of the low-frequency gas vibration source is increased a little. It is possible to deal with it easily. By using such a miniaturized resonance tube, it is possible to make the low frequency device small and compact.

Next, the vibration generating source is provided with a vibration generating section for generating low-frequency gas vibrations which are 180 ° out of phase with each other, and the vibration generating section has first and second vibrations each having a length of about ¼ wavelength. The two resonance tubes are connected to one end side connection part, and the other end side connection part of each vibration transmission part is connected to the container connection part, so that the inside of the container becomes an abdominal part as an opposed resonance device. It is possible to generate various resonance phenomena. As a result, when the object to be processed is placed in the container, the object can be processed by extremely efficiently performing heat exchange or the like by utilizing gas vibration of large amplitude due to resonance.

Two such resonance tubes are provided as a first resonance tube and a second resonance tube, and each of them is integrated in the longitudinal direction (the “longitudinal direction” means the central axis direction of the coil of the coiled resonance tube). Since they are formed integrally, the resonance tubes are arranged in series, and the total length at that time is the shortest. Further, since the container is arranged in parallel and close to the integrally formed resonance tube, the entire low-frequency utilizing device has a compact arrangement. With such a configuration, the entire configuration can be significantly downsized and the installation area can be reduced as compared with the case of providing two sets of devices each including a resonance tube, a container, and a vibration source. In this case, the resonance tube is coiled, so that its overall length is shortened significantly, but it still has a considerable length. On the other hand, it is desirable that the container is as large as possible in processing various objects to be processed. Therefore, by arranging the container and the resonance tube in close proximity to each other as in the present invention, the length of the resonance tube integrated in the longitudinal direction can be effectively used. If the container is placed on the resonance tube, the area occupied by the low frequency use device as a whole can be minimized, and the device can be packaged, resulting in an extremely highly practical device.

Further, if two sets of resonance tubes are integrated, when a piston type pulsator is used as a vibration source, one double-acting type equipped with two vibration generating parts is provided, and each vibration generating part is provided. Can be easily connected to each one end side connection portion of the resonance tube. As a result, the entire device can be downsized and simplified in this respect as well.

According to the invention of claim 2, since the partition member for partitioning between the first connecting portion and the second connecting portion is provided in the container, the direction in which the partition extends in each partitioned portion. It is possible to propagate the gas vibration due to resonance. Therefore, it becomes possible to perform the processing utilizing the vibration in that direction in each of the partitioned parts, and it is possible to form two processing parts that can be processed at the same time. In this case, usually, a partition is partially provided, and a communication part having a cross-sectional area similar to that of each partition is provided at the upper part of the partition to form the opposed resonance device. However, a partition may be provided on the entire surface of the container, and the partitioned parts may be connected to each other by a pipe or the like outside the container. In addition, it is desirable that such a partition be formed so as to be removable from the necessity of transporting the object to be processed and processing a large object to be processed.

According to the third aspect of the present invention, two sets of the two resonance tubes integrally formed as described above are provided, and they are arranged in parallel and close to each other. Therefore, the installation space for the four resonance tubes is minimized. The vibration source is provided with a vibration generation unit that generates two sets of low-frequency gas vibrations that are 180 ° out of phase, and these vibration generation units are the vibration transmission unit of the four resonance tubes and the other end side connection unit. Is connected to the connection part of the container via. In this case, the other end side connection part which is 180 ° out of phase and has an opposite phase is separated and connected to the connection part of the container. Therefore, in the container, an opposite phase is formed between the connection portions, and the resonance phenomenon can be generated as an opposed type between them.

Next, since the container is arranged in proximity to the first to fourth resonance tubes, the space on the resonance tubes is effectively utilized, and the installation area of the entire low frequency utilization device is minimized. . Then, the entire device can be packaged. Therefore, as compared with a configuration in which one resonance tube and one container are configured in a one-to-one relationship, the entire configuration is significantly compacted when the processing capacity is the same, and a device of extremely high practical value appears.

Further, by using a double-acting opposed piston structure that moves in mutually opposite directions as a vibration source, four vibration generating parts can be made with one pulsator. Therefore, the device can be further downsized and simplified. In this case, if the opposing pistons have the same mass, the vibration problem of the device due to the reciprocating inertia of the pistons can be solved.

According to the invention of claim 4, since the partition member for partitioning between the connecting parts having opposite phases is provided in the container, each partition part is divided as in the case of the invention of claim 2. With the use of the vibration of the partition member in the extending direction, it is possible to form two processing parts capable of simultaneous processing.

According to the invention of claim 5, since the coil-shaped pipe is formed by providing the spiral partition between the double pipes, the resonance pipe is further downsized and the pipe is formed. It reduces the amount of waste material and also facilitates the manufacture of the resonance tube.

【Example】

 FIG. 1 shows a schematic structure of a low frequency utilization apparatus of the embodiment. This device is of a double type and has a pulsator 1 as a vibration source, a first resonance tube 2 and a second resonance tube 3, and a container 4.

As shown in an example in FIG. 2, the pulsator 1 is configured by connecting a crank 12 to a motor 11 and a rod 15 connected to a double-acting piston 14 in a cylinder 13 to the crank 12. Due to the reciprocating motion of the piston due to the rotation of the motor, compression and expansion are alternately repeated in the compression chambers 13a and 13b in the cylinder 13, which is the vibration generator, and the compression wave of gas vibration is sent from the outlets 13c and 13d. Will be issued. This compression wave is a low-frequency pulse whose phase is shifted by 180 °.

FIG. 3 shows the structure of the first resonance tube 2 and the second resonance tube 3. These are nozzles 21 and 31 as one end side connecting portions connected to the outlets 13c and 13d of the pulsator 1, and a vibration transmitting portion formed in a coil shape and having a length of about ¼ of the wavelength of the vibration of gas. All the pipe lines 22 and 32 and the nozzles 23 and 33 as the other end side connecting portions are provided, and in this embodiment, the nozzles 21 and 31 are integrally formed through the partition 24 so that they are inside. Has been done. In this way, if the nozzles 21 and 31 are integrated so that they are on the inner side, the connection between these nozzles and the outlet of the pulsator becomes easier, and the distance between the nozzles 23 and 33 becomes longer. It becomes easy to enlarge the connected container 4. However, since the shape of the container 4 varies depending on the size and shape of the object to be processed, it may be better to integrate the resonance tubes 2 and 3 so that the nozzles 23 and 33 are inside.

Since the resonance tubes 2 and 3 have the same structure, the resonance tube 2 will be described below. The pipe line 22 of the common-use tube 2 is formed by arranging a curved inner cylinder 22b in a curved outer cylinder 22a and providing a spiral partition 22c between the outer cylinder 22a and the inner cylinder 22b. It is formed into a shape. The length of the center line 22d of the pipe line 22 is such that the resonance pipe 22 is used in an opposed manner, and when a pulse is applied to the nozzle 21, this portion becomes a node portion, and the outlet portion of the nozzle portion 23 is an abdominal portion. Is a length corresponding to a quarter wavelength of the pulse. For example, if the pulse frequency is 20 Hz, the length is about 4.25 m.

The cross-sectional area of the conduit 22 may be constant. However, when the resonance phenomenon occurs, the moving distance (amplitude) of air particles gradually increases from the resonance node to the abdomen, so that the pressure loss gradually increases if the cross-sectional area of the duct is the same. In order to prevent this, it is desirable to gradually increase the cross-sectional area as shown. Further, the outer cylinder 22a and the inner cylinder 22b do not necessarily have to have a cylindrical shape as shown in FIG. 3, and if the cross section has a certain curvature, it is formed into a rectangular shape as shown in FIG. Good. Such a shape facilitates installation of the device. Further, as shown in FIG. 5 and FIG. 6, a resonance tube having pipe lines 22-1 and 22-2 in which a pipe having a circular or square cross section is formed in a coil shape may be used. When the cross section is circular, the internal volume of the conduit is smaller than the volume occupied by the entire resonance tube, but the flow of the oscillating gas is made uniform. In the case of a rectangular shape, if the cross-sectional area of the conduit is the same in the longitudinal direction, a ring with a rectangular cross section is cut at one point, and this part is twisted and connected to form a resonance tube. It can be manufactured and may be easier to manufacture.

By using the resonance tube as described above, the friction loss due to gas vibration may be increased by about 10% to 20% as compared with the conventional resonance tube. For example, the driving force of the motor of the pulsator 1 may be increased. The loss can be easily supplemented by making the piston 14 a little larger or making the process of the piston 14 a little longer. Further, the friction loss may be reduced by a method such as performing an appropriate surface treatment on the inner surface of the pipe.

3 to 6, an example in which the nozzles 21 and 23 are attached to the upper portion of the outer cylinder 22a is shown in order to make the structure easy to understand, but this attachment position is an appropriate position in the circumferential direction. Can be freely attached to.

Returning to FIG. 1, the container 4 is configured such that the nozzles 23 and 33 at the pulse outlets of the resonance tubes 2 and 3 are coupled with the nozzles 41 and 41 as the first and second connecting portions, respectively. 3 are arranged on the upper side. With such a structure, the low frequency device can be made compact and the installation space can be significantly reduced. Also, the device can be packaged.

The interior of the container 4 is partially partitioned by a partition 42, and lattice-shaped tables 43, 43 on which an object to be processed is placed are attached to the respective storage portions. The partition 42 is removable. Reference numerals 44 and 44 are open / close doors for loading / unloading the object to be processed. With such a structure, when pulses having a phase difference of 180 ° are introduced from the respective inlets, a resonance phenomenon occurs inside as an opposed resonance device. At the position of the object to be processed, a large gas vibration is generated in the vertical direction in the figure, and a gas vibration is generated in the horizontal direction above the partition 42. Then, for example, extremely efficient heat exchange is performed between the vibrating gas and the object to be processed. When the partition 42 is entirely provided up to the upper end of the container 1 for processing a high object to be processed, the parts partitioned by an appropriate method are communicated outside the container 1.

With such a device, it is possible to process two objects at the same time due to its compact structure. However, in some cases, the partition 42 may be removed, the ceiling may be lowered, a large horizontally long object to be treated may be put therein, and this may be treated also by utilizing lateral gas vibration. Further, in the case where the object to be processed is processed in two stages in each accommodation part, the partition 42 is removed when moving to the adjacent accommodation part. It should be noted that it is also possible to let another gas flow in and out of the container 4.

FIG. 7 shows another embodiment of the low frequency utilization apparatus. This device has a structure in which the devices of FIG. 1 are installed in parallel. This device has a pulsator 5 as a vibration source, resonance tubes 2 ′, 3 ′, 6, 7 as first to fourth resonance tubes, and a container 8.

FIG. 9 shows an example of the pulsator 5. This pulsator 5 also has a structure similar to that shown in FIG. 2, but has an opposed piston structure, and is provided with a cylinder portion 52 on the side facing the same cylinder portion 51 as that of FIG. Two sets of gas pulses are generated in the moving cylinder, which are 180 ° out of phase and vibrate at a low frequency. The opposed pistons 53, 54 and the like have substantially the same mass and move in opposite directions. As a result, the reciprocating inertial forces of the pistons 53, 54, etc. are balanced and the vibration of the device is prevented.

Returning to FIG. 7, the first to fourth resonance tubes 2 ′, 3 ′, 6, 7 have the same structure as the resonance tubes 2, 3 of the apparatus of FIG. 1. The container 8 is provided with nozzles 81 ', 82', 83 ', 84 as connecting portions connected to the nozzles 23', 33 ', 63, 73 as connecting portions on the other end side of the four resonance tubes, respectively. The nozzle is supported by the nozzle of the resonance tube so that it is disposed in close proximity to the resonance tube. Similar to the container 4 of FIG. 1, the container 8 is provided with a partition 85 in the direction of the partition 24 'between the two integrally formed resonance tubes. The pulsator 5, the resonance tubes 2 ′, 3 ′, 6, 7 and the container 8 are connected so that the space on one side of each partition 85 has the same phase, and the phase shifts by 180 ° between the two sides. . By such partitioning and connection, as in the case of the device of FIG. 1, a resonance phenomenon can be generated in the container 8 as an opposed resonance device. As a result, by utilizing the vertical vibration, it is possible to process four workpieces simultaneously at two locations, as shown in the figure. However, the partition 85 may not be provided, and the ceiling may be lowered to mainly use the vibration in the left-right direction to process one horizontally long object to be processed. As shown in the figure, the nozzles 81 and 83 and the nozzles 82 and 84, which have the same phase, can be communicated with each other. However, as shown by the alternate long and two short dashes line in the same figure (b), it is also possible to adopt a structure in which these are separated.

In FIG. 7, a partition is not provided in the container 8 in a direction 86 parallel to the longitudinal direction of the resonance tube, but a partition is provided in this direction and four space portions 8a, 8b, 8c, 8d are provided. May be made. In that case, as in the case of the apparatus of FIG. 1, it is possible to remove the partition 85 and use the spaces 8a and 8b and 8c and 8d as one space, respectively. Further, the space portions 8a and 8b have the same phase, and the space portions 8c and 8d have the same phase shifted by 180 ° from the space portion, and the opposed resonance tubes are provided between 8a and 8c and between 8b and 8d. Can also be formed. Thus, the combination of the connection between the four gas vibration generating parts of the pulsator 5, the four resonance tubes, and the container 8 and the partitioning direction of the container 8 are such that the resonance phenomenon occurs in the container 8. , Appropriately selected according to the size of the object to be treated.

FIG. 8 shows still another embodiment of the low frequency utilizing apparatus. This device is provided with nozzles 9-3 and 10-3 in which the nozzles 21 and 31 and the nozzles 23 and 33 of the resonance tubes 2 and 3 shown in FIG. 3 are replaced with each other, and the nozzles 23 and 33 are integrally formed. The resonance tubes 9 and 10 are used. The resonance tubes 9 and 10 correspond to the first resonance tube, the second resonance tube, and the third resonance tube and the fourth resonance tube integrally formed in the longitudinal direction, respectively. In this case, the partition 24 between the resonance tubes as shown in FIG. 3 may be omitted. The resonance tubes 9 and 10 are connected at their both ends to the respective vibration generating portions of the double-acting opposed piston type pulsator 5. In this case, the insides of the resonance tubes 9 and 10 have the same phase, and the phases 9 and 10 are coupled so as to be out of phase by 180 °. The nozzles 9-3 and 10-3 of the resonance tubes 9 and 10 are connected to the nozzles 8'-1 and 8'-2 of the container 8 ', respectively. Then, in the container 8 ', a partition 87 in the direction indicated by reference numeral 86 in FIG. 7C is provided. With such a structure, the portions on both sides of the partition 87 can be made into two processing units utilizing vertical vibration. Moreover, since the connecting portion between the resonance tube and the container is reduced, the structure is further simplified.

According to the apparatus as described above, the installation space is remarkably reduced as compared with the case where the resonance tube and the container are combined in a one-to-one manner and four sets are set. Furthermore, if a double-acting opposed piston type as shown in FIG. 9 is used as the pulsator 5, it is sufficient to install only one for each of the four resonance tubes, and the apparatus can be made more compact. In addition, it becomes possible to package the device, which would streamline production and assembly work.

By reasonably combining this resonance tube with a container that resonates, the low-frequency utilization device can be made significantly compact, and the installation area in factories, etc. can be reduced. And, it is possible to make the low frequency device extremely useful.
