(Embodiment 1)
Hereinafter, the cleaning device system 20 and the cleaning method according to the first embodiment of the present invention will be described with reference to the drawings. In each of the following embodiments, the same or corresponding configurations may be designated by the same reference numerals and the description thereof may be omitted as appropriate. Further, in the drawings of the present application, Cartesian coordinates of XYZ are shown for reference. Of these Cartesian coordinates, the Z direction corresponds to the upper side, and the −Z direction corresponds to the lower side (the direction in which gravity acts).

FIG. 1 is a diagram for explaining a partial configuration of an incinerator facility 10 in which the cleaning device system 20 according to the present embodiment is used. In the incinerator according to this embodiment, a pipe is used as an example of the object to be cleaned. Specifically, the object to be cleaned according to the present embodiment is a pipe of the incinerator 10 for waste (specifically, a pipe for heat exchange). The incinerator 10 shown in FIG. 1 includes a first chamber 11a, a second chamber 11b, and a third chamber 11c as heat exchange chambers for cooling the combustion gas (GA) after burning waste or the like. .. In FIG. 1, the illustration of the internal structures of the first chamber 11a, the second chamber 11b, and the third chamber 11c is omitted. A plurality of pipes through which the refrigerant passes are arranged in each of the first chamber 11a, the second chamber 11b, and the third chamber 11c. The combustion gas generated in the incinerator that burns waste etc. is cooled by exchanging heat with the refrigerant passing through the piping while passing through the first chamber 11a, the second chamber 11b and the third chamber 11c. Will be done.

FIG. 2 is a diagram showing a state in which cleaning is performed by the cleaning device system 20. The cleaning device system 20 according to the present embodiment is applied to the third room 11c of the incinerator facility 10 as an example, and specifically, a plurality of pipes (pipes 12-1a to 12-) of the third room 11c. It is used for cleaning 4c). In addition, in FIG. 2, a plurality of pipes are shown in cross section. Each of these pipes extends in the horizontal direction (direction parallel to the Y axis in FIG. 2).

The pipes 12-1a, 12-2a, 12-3a, 12-4a (these pipes are referred to as the first pipe row) are the pipes 12-1b, 12-2b, 12-3b, 12-4b (these pipes). The pipes are arranged on the −X direction side with respect to the second pipe row). The pipes 12-1c, 12-2c, 12-3c, and 12-4c (these pipes are referred to as a third pipe row) are arranged on the X direction side of the second pipe row. Since the arrangement density of the pipe rows in the third chamber 11c is high (in other words, the distance between the adjacent pipe rows and the pipe rows is narrow), the cleaning worker can build a scaffold when performing the cleaning work. It is not easy to secure enough space. However, even in such a place, as will be described later, the cleaning work can be easily performed according to the cleaning device system 20 according to the present embodiment.

The cleaning device system 20 includes at least one cleaning device. That is, the cleaning device system 20 may be provided with only one cleaning device, or may be provided with a plurality of cleaning devices. As an example, the cleaning device system 20 according to the present embodiment includes a plurality of cleaning devices. Specifically, the cleaning device system 20 includes six cleaning devices (cleaning devices 30-1a, 30-2a, 30-3a, 30-1b, 30-2b, 30-3b) as an example. Since the configurations of the respective cleaning devices are the same, the configuration of the cleaning device will be described by taking the cleaning device 30-1a as an example.

FIG. 3 is a front view of the cleaning device 30-1a. FIG. 4A is a cross-sectional view taken along the line A1-A1 of FIG. FIG. 4 (B) is an enlarged view of a portion B1 of FIG. 4 (A). FIG. 5 is a cross-sectional view of the B2 portion of FIG. Specifically, FIG. 5 schematically shows a cross section of the B2 portion of FIG. 3 cut along a surface including the axis of the pipe 31-1a.

As shown in FIG. 3, the cleaning device 30-1a includes a pipe 31-1a, a rotating body 32, connecting members 38a and 38b, rotating guides 33a and 33b, and a wire 34.

The pipe 31-1a extends in a direction parallel to the Z axis. That is, the axial direction of the pipe 31-1a according to the present embodiment is the vertical direction (direction perpendicular to the ground). The fluid (FL) pumped from the fluid supply device 150 (shown in FIG. 2) is supplied to the pipe 31-1a. As this fluid, a gas or a liquid can be used. As the gas, for example, air, an inert gas, or the like can be used. As the liquid, for example, water, a cleaning liquid containing a cleaning agent in water, or the like can be used. In this embodiment, air is used as an example of the fluid. When air is used as the fluid, for example, an air compressor, an air cylinder, or the like can be used as the fluid supply device 150. When a liquid is used as the fluid, a fluid pump or the like can be used as the fluid supply device 150.

If, for example, a fluid supply device provided in advance in the incinerator 10 is used as the fluid supply device 150, the cost of separately preparing the fluid supply device can be reduced.

As shown in FIGS. 4A and 4B, a fluid passing through the inside of the pipe 31-1a is injected outward in the radial direction of the pipe 31-1a onto the side wall 31a of the pipe 31-1a. At least one nozzle hole 35 for making the nozzle hole 35 is provided. As an example, the pipe 31-1a according to the present embodiment is provided with a plurality of nozzle holes 35 in the circumferential direction of the pipe 31-1a.

As shown in FIGS. 3, 4 (A) and 4 (B), the rotating body 32 is arranged outside in the radial direction of the pipe 31-1a. The axis of the rotating body 32 coincides with the axis of the pipe 31-1a. The rotating body 32 is fitted in the pipe 31-1a so as to be rotatable relative to the pipe 31-1a. The rotating body 32 is driven by the fluid injected from the nozzle hole 35 of the pipe 31-1a and rotates. Further, the rotating body 32 includes an injection port 36 (shown in FIG. 4B) that injects the fluid after being subjected to the rotation of the rotating body 32 toward the outside in the radial direction of the rotating body 32. ing. Specifically, the rotating body 32 according to the present embodiment has the following configuration.

First, the rotating body 32 according to the present embodiment includes a plurality of blades 37. The plurality of blades 37 are arranged so as to surround the circumference of the pipe 31-1a. The connecting members 38a and 38b are formed of an annular member. The Z-direction side ends of the plurality of blades 37 are connected by a connecting member 38a, and the −Z-direction side ends of the plurality of blades 37 are connected by a connecting member 38b. The connecting members 38a and 38b rotate integrally with the rotating body 32 (blades 37) when the rotating body 32 rotates.

The connecting members 38a and 38b are rotatably connected to the pipe 31-1a by the rotation guides 33a and 33b with respect to the pipe 31-1a. Specifically, the rotation guides 33a and 33b are fixed to the pipe 31-1a by being fitted to the pipe 31-1a. As a result, the rotation guides 33a and 33b do not rotate when the rotating body 32 rotates. Then, as shown in FIG. 5, the rotation guide 33a is configured so that when it is fitted to the pipe 31-1a, an annular groove 33a-1 is formed between the rotation guide 33a and the pipe 31-1a. By fitting the connecting member 38a into the groove 33a-1, the connecting member 38a rotates with respect to the pipe 31-1a without being displaced in the axial direction (Z-axis direction) with respect to the pipe 31-1a.

The rotation guide 33b has the same configuration as the rotation guide 33a. That is, the rotation guide 33b is also configured so that when it is fitted to the pipe 31-1a, an annular groove is formed between the rotation guide 33b and the pipe 31-1a. By fitting the connecting member 38b into the groove between the rotation guide 33b and the pipe 31-1a, the connecting member 38b rotates with respect to the pipe 31-1a without being displaced in the axial direction with respect to the pipe 31-1a.

As shown in FIG. 4B, the rotating body 32 rotates relative to the pipe 31-1a when the blades 37 receive the pressure of the fluid injected from the nozzle hole 35 of the pipe 31-1a. (That is, it is driven by the fluid injected from the nozzle hole 35 and rotates). For reference, in FIG. 4B, the rotation direction of the rotating body 32 is illustrated by "RT".

Further, a gap 37a through which the fluid after being injected from the nozzle hole 35 can pass is provided between the adjacent blades 37 and the blades 37. The gap 37a has a function as the injection port 36 described above. As a result, the fluid after being injected from the nozzle hole 35 is injected outward from the gap 37a (injection port 36) in the radial direction of the rotating body 32. The object to be cleaned is purged by the fluid injected from the injection port 36. The rotating body 32 has the above configuration.

As shown in FIGS. 3 and 4A, the wire 34 according to the present embodiment is connected to the rotating body 32. Specifically, the wire 34 according to the present embodiment is connected to the outer peripheral surface of the blade 37 of the rotating body 32. As a result, the wire 34 rotates together with the rotating body 32 when the rotating body 32 rotates.

Further, one end of the wire 34 according to the present embodiment is connected to the blade 37, and the other end is connected to "a portion different from the portion of the blade 37 to which one end of the wire 34 is connected". As a result, the wire 34 has a loop shape as a whole. The connection point of the wire 34 is not limited to the rotating body 32 as long as the wire 34 can rotate together with the rotating body 32 when the rotating body 32 rotates. The wire 34 may be connected to a member that rotates integrally with the rotating body 32 (for example, in the present embodiment, connecting members 38a, 38b, etc.).

Further, the number of wires 34 included in the cleaning device 30-1a according to the present embodiment is, for example, a plurality. Specifically, the cleaning device 30-1a includes two wires 34. In the present embodiment, the two wires 34 are connected to the blades 37 so that the other wire 34 is located on the opposite side of the rotating body 32 of the one wire 34. However, the number of wires 34 is not limited to two, and may be one or three or more.

When the wire 34 rotates together with the rotating body 32, the wire 34 comes into contact with the object to be cleaned to clean the object to be cleaned. Specifically, the wire 34 according to the present embodiment is composed of a string-shaped body (string-shaped member) having flexibility and flexibility. Since this wire 34 does not have self-supporting property, when the rotation of the rotating body 32 is stopped, the portion not connected to the rotating body 32 (referred to as a non-connecting portion) is -Z due to the action of gravity. It hangs in the direction. On the other hand, when the rotating body 32 rotates, the wire 34 receives centrifugal force and its non-connecting portion is located in the outer direction in the radial direction of the rotating body 32 (not in the present embodiment). The connection will be located approximately horizontally). Then, the wire 34 removes the foreign matter (dust, etc.) adhering to the surface of the cleaning object by contacting at least a part of the non-connecting portion of the wire 34 with the cleaning object. Remove. In this way, the wire 34 cleans the object to be cleaned.

The "diametrical length of the rotating body 32" of the wire 34 may be a length that allows the wire 34 to come into contact with the object to be cleaned when the rotating body 32 rotates, and its specific value is particularly limited. It's not something. The length of the wire 34 may be appropriately set in consideration of the distance between the object to be cleaned and the rotating body 32 and the like.

The specific material of the wire 34 is not particularly limited, and for example, a metal or a non-metal may be used as the material of the wire 34. As the metal, for example, a metal containing iron, copper, aluminum or the like as a main component may be used. As the non-metal, for example, one containing polyamide or the like as a main component may be used.

If the wire 34 has a hardness lower than that of the object to be cleaned (pipe in this embodiment), the damage to the object to be cleaned by the wire 34 can be suppressed to a small extent.

The surface texture of the wire 34 is not particularly limited, and may be a "smooth surface texture" having no irregularities or a "non-smooth surface texture" having irregularities. It should be noted that cleaning with the wire 34 can be performed more effectively when the surface texture of the wire 34 is non-smooth than when it is smooth.

Further, the shape of the wire 34 is not limited to the loop shape as in the present embodiment. For example, the wire 34 may have only one end connected to the blade 37 and the other end not connected to the blade 37. Even in this case, the wire 34 can clean the object to be cleaned by contacting the portion of the wire 34 that is not connected to the rotating body 32 with the object to be cleaned when the rotating body 32 is rotated.

It should be noted that when the wire 34 has a loop shape as in the present embodiment, the cleaning range of the object to be cleaned by the wire 34 can be easily widened as compared with the case where the wire 34 does not have a loop shape. Thereby, the cleaning efficiency can be improved.

With reference to FIG. 2 again, as described above, the cleaning device system 20 according to the present embodiment includes a plurality of cleaning devices (cleaning devices 30-1a, 30-2a, 30-3a, 30-1b, 30-2b). , 30-3b). Further, the cleaning device system 20 includes a connecting header pipe 50 and a plurality of joints (joints 60a, 60b, 60c, 60d, 60e, 60f).

The connecting header pipe 50 is composed of pipes extending in the horizontal direction. A hose 151 is connected to the connecting header pipe 50. The upstream end of the hose 151 is connected to the fluid supply device 150 described above. The fluid pumped from the fluid supply device 150 is supplied to the connecting header pipe 50 via the hose 151. The connecting header pipe 50 is provided with a discharge port 51a and a discharge port 51b. The discharge port 51a is located on the −X direction side with respect to the discharge port 51b.

The discharge port 51a of the connecting header pipe 50 and the Z-direction side end of the pipe 31-1a of the cleaning device 30-1a are connected by a joint 60a. The −Z direction side end of the pipe 31-1a of the cleaning device 30-1a and the Z direction side end of the pipe 31-2a of the cleaning device 30-2a are connected by a joint 60b. The −Z direction side end of the pipe 31-2a of the cleaning device 30-2a and the Z direction side end of the pipe 31-3a of the cleaning device 30-3a are connected by a joint 60c. The −Z direction side end of the pipe 31-3a is closed.

The discharge port 51b of the connecting header pipe 50 and the Z-direction side end of the pipe 31-1b of the cleaning device 30-1b are connected by a joint 60d. The −Z direction end of the pipe 31-1b of the cleaning device 30-1b and the Z direction end of the pipe 31-2b of the cleaning device 30-2b are connected by a joint 60e. The −Z direction end of the pipe 31-2b of the cleaning device 30-2b and the Z direction end of the pipe 31-3b of the cleaning device 30-3b are connected by a joint 60f. The −Z direction end of the pipe 31-3b is closed.

The specific type of the plurality of joints is not particularly limited, and a known joint that connects the two pipes can be used. If a removable joint (for example, a one-touch joint or the like) is used as the plurality of joints, the cleaning device can be easily attached and detached. Therefore, in the present embodiment, a removable joint is used as an example of a plurality of joints.

Further, the cleaning device system 20 sets the cleaning device (cleaning device 30-1a to cleaning device 30-3b) in the extending direction of the object to be cleaned (specifically, in the present embodiment, the extending direction of the pipe). A traveling device 70 for traveling is provided. In the present embodiment, the extending direction of the object to be cleaned is the horizontal direction, specifically, the direction parallel to the Y axis. The configuration of the traveling device 70 is as follows.

FIG. 6 is a front view of the traveling device 70. The traveling device 70 according to the present embodiment includes legs 71a, 71b, wheels 72a, 72b, connecting portions 73, and locking plates (locking plates 74-1a, 74-2a, 74-1b, 74-2b). ) And.

The leg portion 71a is arranged on the −X direction side with respect to the leg portion 71b. The wheels 72a are arranged at the -Z direction side end portion of the leg portion 71a. The wheels 72b are arranged at the −Z direction side end portion of the leg portion 71b. The connecting portion 73 connects the Z-direction side end portion of the leg portion 71a and the Z-direction side end portion of the leg portion 71b.

The wheel 72a runs on the pipe 12-1a in the extending direction of the pipe 12-1a. The wheels 72b travel on the pipe 12-1c in the extending direction of the pipe 12-1c.

The locking plates 74-1a and 74-2a are provided on the "plane facing the leg 71b" of the leg 71a. The locking plate 74-1a is located on the Z direction side of the locking plate 74-2a. The locking plates 74-1b and 74-2b are provided on the "plane facing the leg 71a" of the leg 71b. The locking plate 74-1b is located on the Z direction side of the locking plate 74-2b. The ground clearances of the locking plate 74-1a and the locking plate 74-1b are set to the same value. The ground clearance of the locking plate 74-2a and the locking plate 74-2b is also set to the same value.

The connecting header pipe 50 of the cleaning device system 20 is placed on the locking plate 74-1a and the locking plate 74-1b, or on the locking plate 74-2a and the locking plate 74-2b. The connecting header tube 50 according to the present embodiment is placed on the locking plate 74-1a and the locking plate 74-1b as an example.

In this way, with the connecting header pipe 50 placed on the locking plate 74-1a and the locking plate 74-1b, the traveling device 70 is traveled in the extending direction of the object to be cleaned (piping). , The cleaning device can be easily moved in the extending direction of the object to be cleaned.

In the present embodiment, the number of stages of the locking plate is two, but the number of stages of the locking plate is not limited to this. The number of stages of the locking plate may be one or three or more. However, as in the present embodiment, the height of the cleaning device can be easily changed by having a plurality of stages of the locking plates.

Subsequently, an example of the usage mode of the cleaning device system 20 according to the present embodiment will be described. With reference to FIG. 2 described above, when the fluid is supplied from the fluid supply device 150 to the cleaning device system 20 via the hose 151, the fluid passes through the connecting header pipe 50 and then through the discharge ports 51a and 51b, respectively. Then, it flows into each cleaning device. When the fluid flows into each cleaning device, the rotating body 32 of the cleaning device rotates as described above in FIGS. 3 and 4. During the rotation of the rotating body 32, the fluid is injected outward in the radial direction of the rotating body 32 from the injection port 36 (the gap 37a between the adjacent blades 37), and the wire 34 also rotates. As a result, purge cleaning with the fluid injected from the injection port 36 and cleaning with the wire 34 are performed at the same time. Further, at the time of cleaning, the purging cleaning and the cleaning may be performed while the cleaning device is driven in the extending direction of the object to be cleaned by using the traveling device 70.

The cleaning method according to the present embodiment is realized by the cleaning device system 20 described above. That is, in the cleaning method according to the present embodiment, the rotating body 32 is rotated relative to the pipe by passing the fluid through the pipe of the cleaning device of the cleaning device system 20, and the rotating body 32 is rotated from the rotating body 32 to the rotating body. This is a cleaning method for cleaning an object to be cleaned by bringing a rotating wire 34 into contact with the object to be cleaned while injecting fluid outward in the radial direction of 32.

Subsequently, the action and effect of this embodiment will be described. First, according to the present embodiment, the object to be cleaned can be cleaned by the wire 34 while injecting a fluid outward in the radial direction of the rotating body 32 from the injection port 36 of the rotating rotating body 32. As a result, purge cleaning with the fluid injected from the injection port 36 and cleaning with the wire 34 can be performed at the same time. Therefore, for example, as compared with the case where only cleaning can be performed at one time or only purging cleaning can be performed, a wide range of the object to be cleaned can be simultaneously cleaned by a simple method without any trouble. Further, since the wire 34 is formed of a string-like body, when the wire 34 comes into contact with the object to be cleaned, the wire 34 can be easily deformed so as to follow the shape of the object to be cleaned. In this respect as well, a wide range of objects to be cleaned can be cleaned at the same time by a simple method without any trouble. Further, the wire 34 adheres to the shape of the object to be cleaned and can be freely adjusted in shape so as to wrap the object to be cleaned, and has a high bending effect, so that foreign matter adhering to the object to be cleaned is scraped off. The function to drop is high. Therefore, since the wire 34 has a high effect of removing foreign matter adhering to the object to be cleaned, it is possible to clean the foreign matter firmly adhering to the object to be cleaned.

Further, according to the present embodiment, since the pipes (specifically, a plurality of pipes) are used as the objects to be cleaned, the purge cleaning and the cleaning can be performed simultaneously on the plurality of pipes. As a result, the efficiency of the pipe cleaning work can be improved. As a result, the work load of the cleaning worker can be reduced. As a result, the health condition of the cleaning worker can be maintained in good condition.

Further, according to the present embodiment, since the pipe as the object to be cleaned is the pipe of the incinerator facility 10 (that is, the pipe for heat exchange), the efficiency of the cleaning work of the incinerator facility 10 can be improved. This makes it possible to maintain a good health condition of the cleaning worker in that the chance of the cleaning worker being exposed to soot and dust during the cleaning work can be reduced. Specifically, the present embodiment is preferably applied to a heat exchange pipe used in an incinerator, an air preheater, or the like of an incinerator 10.

Further, according to the present embodiment, a fluid is used as a driving source for rotating the rotating body 32, and the fluid after being subjected to the rotation of the rotating body 32 is effectively used as a "purge cleaning fluid". ing. As a result, the configuration of the cleaning device 30 can be simplified.

Further, according to the present embodiment, since the rotating body 32 is rotated by the fluid, the cleaning device can be self-cleaned by the fluid. As a result, the maintenance cost of the cleaning device can be reduced. Further, depending on the fluid, for example, purge cleaning of the groove 33a-1 and the injection port 36 and purge cleaning of the inside of the pipe can be performed, so that the rotation function of the cleaning device can be maintained and the purge function (the fluid directed to the outside). It is also possible to maintain the purge function).

Further, according to the present embodiment, since the rotating body 32 includes the plurality of blades 37, the blades 37 can effectively receive the pressure from the fluid injected from the nozzle hole 35 of the pipe. As a result, the rotating body 32 can be effectively rotated by the fluid injected from the nozzle hole 35.

Further, according to the present embodiment, since the joints 60a, 60b, 60c, 60d, 60e, 60f for connecting the pipes in the plurality of cleaning devices to each other are provided, the plurality of cleaning devices can be easily connected. can. Further, since the cleaning device system 20 includes a plurality of cleaning devices, it is possible to clean a wide range of the object to be cleaned as compared with the case where the cleaning device system 20 includes only one cleaning device. Specifically, according to the present embodiment, it is possible to purge and clean a plurality of pipes (plural rows or a plurality of stages of pipes) existing around the plurality of cleaning devices. Therefore, high cleaning efficiency can be obtained.

Further, according to the present embodiment, since the traveling device 70 is provided, it is possible to clean the object to be cleaned while traveling the cleaning device. As a result, it is possible to clean a wide range of the object to be cleaned as compared with the case where the traveling device 70 is not provided.

Further, according to the present embodiment, cleaning can be performed without providing a scaffold for cleaning work. As a result, for example, even for a cleaning object for which it is difficult to secure a sufficient space for scaffolding due to a high arrangement density of piping rows, the cleaning device system 20 is applied to the cleaning object. A wide area can be cleaned at the same time.

The cleaning work by the cleaning device system 20 described above is basically performed while the incinerator 10 is stopped (specifically, the incinerator of the incinerator 10 is stopped). As described above, according to the cleaning device system 20 according to the present embodiment, a wide range of objects to be cleaned can be cleaned at the same time (that is, because the cleaning efficiency is high), so that the cleaning frequency is higher than that of the prior art. It is easy to increase (the number of cleanings per unit year). This makes it easy to maintain good performance of the incinerator 10.

(Embodiment 2)
Subsequently, the cleaning device system 20A and the cleaning method according to the second embodiment of the present invention will be described. As an example, the cleaning device system 20A according to the present embodiment is used for cleaning the water pipe wall in the second room 11b of the incinerator 10 shown in FIG. 1 described above.

FIG. 7 is a perspective view showing a part of the second room 11b of the incinerator 10. A plurality of water pipe walls (water pipe walls 13a, 13b, 13c, 13d, 13e) are provided in the second chamber 11b. Each water pipe wall is composed of an aggregate of a plurality of pipes. That is, in one water pipe wall, a plurality of pipes are arranged in a row.

Further, the water pipe wall 13b is provided with an inspection port 15a. An inspection port 15b is also provided on the wall surface of the third chamber 11c adjacent to the second chamber 11b.

The combustion gas (GA) generated in the first chamber 11a passes through the inside of the second chamber 11b from the upper side to the lower side, and then flows into the third chamber 11c. At this time, heat exchange is performed between the combustion gas and the refrigerant on the wall of the water pipe. By the way, soot dust (DU) contained in the combustion gas may adhere to such a water pipe wall. As an example, the cleaning device 30A according to the present embodiment is used to clean and remove the soot and dust adhering to the water pipe wall by using the water pipe wall as an object to be cleaned.

FIG. 8 is a perspective view showing a state in which the cleaning device system 20A according to the present embodiment is applied to the incinerator facility 10. The cleaning device system 20A according to the present embodiment is installed and used on the scaffold 160 as an example. Specifically, the scaffold 160 is a stand for facilitating the installation of the cleaning device system 20A (this scaffold 160 is not a so-called high-altitude scaffold). Fluid is supplied to the cleaning device 30A from the fluid supply device 150 via the hose 151. As the fluid, the same fluid as in the first embodiment described above can be used. The fluid supply device 150 according to the present embodiment is arranged outside the third chamber 11c as an example. Therefore, the hose 151 according to the present embodiment enters the second chamber 11b after entering the third chamber 11c through the inspection port 15b, and is connected to the end portion of the pipe 31-1c on the −Z direction side. ..

FIG. 9 is a perspective view of the cleaning device system 20A according to the present embodiment. The cleaning device system 20A includes a cleaning device 30A, a fixing base 90, and a runout suppressing device 100. Details of the cleaning device 30A will be described later.

The fixing base 90 is a member for fixing the pipe of the cleaning device 30A to the scaffold 160. Specifically, in the fixing base 90 according to the present embodiment, the −Z direction side end of the pipe of the cleaning device 30A is fixed to the scaffold 160.

Here, the pipe of the cleaning device 30A according to the present embodiment is divided into a plurality of pipes. Specifically, the pipe of the cleaning device 30A is divided into pipes 31-1c, 31-2c, 31-3c, and 31-4c as an example. The pipe 31-2c is arranged on the Z direction side of the pipe 31-1c, the pipe 31-3c is arranged on the Z direction side of the pipe 31-2c, and the pipe 31-4c is arranged on the Z direction side of the pipe 31-3c. Is located in. The fluid flowing into the pipe 31-1c through the hose 151 passes through the pipe 31-1c, the pipe 31-2c, the pipe 31-3c, and the pipe 31-4c in this order. The pipes 31-2c and 31-3c are provided with nozzle holes 35 as in the first embodiment described above. A plurality of nozzle holes 35 are provided in the extending direction of the pipe 31. The fluid passing through the pipe 31 is injected from the nozzle hole 35 toward the outside of the pipe 31.

In the present embodiment, the Z-direction side end of the pipe 31-4c is closed to such an extent that a large amount of fluid inside the pipe 31-4c can be prevented from leaking to the outside from this end, while being described later. A hole is provided so that the moving wire 82 of the moving device 80 can be inserted. With reference to FIG. 8 again, a protective tube 152 is provided in the vicinity of the inspection port 15a. A part of the moving wire 82 passes through the inside of the protective tube 152. The protective tube 152 prevents the moving wire 82 from coming into direct contact with the inspection port 15a.

As shown in FIG. 9, the runout suppressing device 100 is a device that suppresses the runout of the pipe of the cleaning device 30A. Specifically, the runout suppression device 100 according to the present embodiment includes, as an example, a fitting member 101 fitted to the pipe, and an engaging member that engages the pipe and the object to be cleaned (water pipe wall). (Engagement members 102a, 102b, 102c, 102d) are provided. By engaging the engaging member with the pipe and the object to be cleaned, the pipe is prevented from swinging in the direction approaching the object to be cleaned.

Specifically, one end of the engaging members 102a, 102b, 102c, 102d is connected to the fitting member 101. Further, wheels 103 are provided at the other ends of the engaging members 102a, 102b, 102c, and 102d according to the present embodiment, respectively. The engaging member 102a extends in the −Y direction starting from the end on the pipe 31 side. The engaging member 102b extends in the −X direction starting from the end on the pipe 31 side. The engaging member 102c extends in the Y direction starting from the end on the pipe 31 side. The engaging member 102d extends in the X direction starting from the end on the pipe 31 side. As described above, the engaging member of the runout suppressing device 100 according to the present embodiment extends in four directions.

In the case of the example shown in FIG. 8, in the runout suppressing device 100, the engaging member 102b is engaged with the water pipe wall 13a and the pipe. Specifically, the engaging member 102b is indirectly engaged with the water pipe wall 13a and the pipe via the wheel 103 and the fitting member 101. Similarly, in the runout suppressing device 100, the engaging member 102c indirectly engages the water pipe wall 13b with the pipe. As a result, it is effectively suppressed that the pipe swings in the direction approaching the water pipe wall 13a and the water pipe wall 13b.

The runout suppression device 100 may not be provided with the wheels 103. However, since the runout suppressing device 100 includes the wheels 103, it is possible to effectively prevent the engaging member from coming into direct contact with the object to be cleaned. As a result, the cleaning worker can easily move the pipe.

Further, the engaging member may have a spring structure capable of expanding and contracting a predetermined length in the longitudinal direction of the engaging member. To give an example of this, for example, the engaging member may be partially composed of a spring. According to this configuration, since the engaging member can be expanded and contracted by a predetermined length in the longitudinal direction thereof, the wheel 103 can be easily attached to the water pipe wall even when the distance between the pipe and the object to be cleaned is not uniform. Can be brought into contact with. As a result, the runout suppression effect of the runout suppression device 100 can be more effectively exerted.

FIG. 10 is a front view of the cleaning device 30A according to the present embodiment. FIG. 11 is a cross-sectional view taken along the line A2-A2 of FIG. FIG. 12A is a cross-sectional view taken along the line A3-A3 of FIG. In FIG. 12A, the bearing 39 and the magnetic force generator 81, which will be described later, are not shown. 12 (B) is an enlarged view of the B3 portion of FIG. 12 (A).

As shown in FIG. 10, the cleaning device 30A according to the present embodiment includes pipes (pipes 31-1c, 31-2c, 31-3c, 31-4c), a rotating body 32, a connecting member 38c, and a wire 34. And a bearing 39.

The rotating body 32 is arranged outside in the radial direction of the pipe. The rotating body 32 is fitted in the pipe so as to be rotatable relative to the pipe. Specifically, the rotating body 32 according to the present embodiment includes a plurality of blades 37. Since the configuration of the blade 37 is the same as that of the first embodiment described above, the description thereof will be omitted. The connecting member 38c connects the end portions of the plurality of blades 37 on the −Z direction side. As a result, the blade 37 and the connecting member 38c rotate integrally. As shown in FIG. 11, in the present embodiment, the Z-direction side ends of the plurality of blades 37 are connected to the outer bearing portion 39b of the bearing 39. As a result, the blade 37 and the outer bearing portion 39b rotate integrally.

As shown in FIG. 10, the wire 34 according to the present embodiment is different from the above-described first embodiment in that it is connected to the outer peripheral surface of the buoyancy blade 40. Except for this point, the configuration of the wire 34 is the same as that of the first embodiment, and thus a detailed description of the wire 34 will be omitted. As will be described later, the buoyancy blade 40 rotates integrally with the rotating body 32. Therefore, similarly to the first embodiment, the wire 34 according to the present embodiment can also clean the object to be cleaned by rotating together with the rotating body 32 and coming into contact with the object to be cleaned when the rotating body 32 rotates. can.

The connection point of the wire 34 may be a place where the wire 34 can rotate together with the rotating body 32 when the rotating body 32 rotates, and may be connected to the rotating body 32 and integrally with the rotating body 32. It may be connected to a rotating member. In the present embodiment, the wire 34 is connected to the buoyancy blade 40 (a member that rotates integrally with the rotating body 32), but the present invention is not limited to this. As another example, the wire 34 may be connected to, for example, a blade 37 of the rotating body 32 as in the first embodiment.

As shown in FIG. 11, the bearing 39 is composed of a rolling bearing. Specifically, the bearing 39 according to the present embodiment includes the above-mentioned outer bearing portion 39b, as well as an inner bearing portion 39a and a rolling element 39c. The inner bearing portion 39a is fitted in the pipe so as to be movable in the extending direction of the pipe with respect to the pipe. The outer bearing portion 39b described above is arranged outside in the radial direction of the inner bearing portion 39a via the rolling element 39c. The outer bearing portion 39b can rotate relative to the inner bearing portion 39a.

As shown in FIG. 12B, also in the present embodiment, as in the first embodiment, the rotating body 32 is driven by the fluid (FL) injected from the nozzle hole 35 of the pipe with respect to the pipe. It rotates relatively. Then, the fluid after being injected from the nozzle hole 35 is injected outward from the gap 37a (that is, the injection port 36) between the blades 37 and the blades 37 in the radial direction of the rotating body 32. Further, when the rotating body 32 rotates, the wire 34 rotates together with the rotating body 32 and comes into contact with the object to be cleaned. As a result, the wire 34 cleans the object to be cleaned.

Further, as shown in FIG. 11, the cleaning device system 20A according to the present embodiment includes a moving device 80 that moves the rotating body 32 in the extending direction of the pipe. The moving device 80 according to the present embodiment includes a magnetic force generator 81 and a moving wire 82. Further, the moving device 80 according to the present embodiment also includes the buoyancy blade 40 as a part of its constituent elements.

The magnetic force generator 81 is composed of a substance that generates a magnetic force. The specific type of the magnetic force generator 81 is not particularly limited, but in the present embodiment, a magnet is used as an example of the magnetic force generator 81. As this magnet, a permanent magnet, an electromagnet, or the like can be used. Further, the magnetic field generator 81 according to the present embodiment is arranged inside the pipe 31 as an example.

The moving wire 82 is connected to the magnetic force generator 81. The magnetic force generator 81 is suspended by a moving wire 82. The end of the moving wire 82 on the side opposite to the side of the magnetic field generator 81 is arranged in a chamber different from the second chamber 11b. With this configuration, the cleaning worker can remotely control the magnetic force generator 81 in the pipe by winding up or lowering the moving wire 82 in a room separate from the second room 11b. The moving wire 82 can be wound and unwound by using, for example, a manual reel or an electric reel.

Further, the inner bearing portion 39a of the bearing 39 has a property of being attracted by a magnetic force. Specifically, the inner bearing portion 39a according to the present embodiment is made of a ferromagnetic material. As a result, the inner bearing portion 39a can move in the extending direction of the pipe by being attracted by the magnetic force of the magnetic force generator 81. By moving the inner bearing portion 39a in this way, the rotating body 32 can also move in the extending direction of the pipe. As described above, the moving device 80 according to the present embodiment uses the magnetic force generated by the magnetic force generating body 81 to move the rotating body 32 in the extending direction of the pipe.

The outer bearing portion 39b and the rolling element 39c of the bearing 39 may be made of a ferromagnetic material, or may be made of a non-ferromagnetic material (a material having a property of not being attracted by a magnetic force). However, if the outer bearing portion 39b and the rolling element 39c are made of a non-ferromagnetic material, it is possible to suppress the rotation of the outer bearing portion 39b and the rolling element 39c from being affected by the magnetic force from the magnetic field generator 81. can.

As shown in FIG. 11, the buoyancy blade 40 is connected to the outer peripheral surface of the outer bearing portion 39b. As a result, the buoyancy blade 40 rotates integrally with the blade 37 (rotating body 32). The buoyancy blade 40 is configured to generate buoyancy when rotated. As a result, the rotating body 32 can move in the Z direction (upward) by utilizing the buoyancy generated by the buoyancy blade 40. Further, when the rotation of the rotating body 32 becomes slow and the buoyancy generated by the buoyancy blade 40 becomes small as a result, the rotating body 32 can also move in the −Z direction (downward). As described above, the moving device 80 according to the present embodiment moves the rotating body 32 by utilizing the buoyancy generated by the buoyancy blade 40.

The moving device 80 may include only one of the magnetic field generator 81 and the buoyancy blade 40. However, when the moving device 80 is provided with both the magnetic force generating body 81 and the buoyancy blade 40, the rotating body 32 can be easily moved as compared with the case where either one is provided.

Subsequently, an example of the usage mode of the cleaning device system 20A according to the present embodiment will be described. With reference to FIG. 8 described above, when the fluid is supplied from the fluid supply device 150 to the cleaning device system 20A via the hose 151 and the fluid flows into the cleaning device 30A, the rotating body 32 of the cleaning device 30A moves. Rotate. During the rotation of the rotating body 32, the fluid is injected outward in the radial direction of the rotating body 32 from the injection port 36 (the gap 37a between the adjacent blades 37), and the wire 34 also rotates. As a result, the water pipe wall is simultaneously purged with the fluid injected from the injection port 36 and cleaned with the wire 34.

Further, at the time of cleaning, the moving wire 82 of the moving device 80 can be used to perform purge cleaning and cleaning while moving the rotating body 32 in the extending direction of the pipe. In this case, at the time of cleaning, the rotating body 32 may be moved from the lower end side to the upper end side of the pipe while temporarily stopping the rotating body 32 at a predetermined position in the extending direction of the pipe (for example, while stopping for about 30 seconds). good. Further, in the case of the present embodiment, the buoyancy blade 40 is provided, and the buoyancy blade 40 generates buoyancy when the rotating body 32 rotates, so that the rotating body 32 can be easily moved.

In the above-described embodiment, the cleaning device system 20A includes one cleaning device 30A, but the present invention is not limited to this configuration. The cleaning device system 20A may include a plurality of cleaning devices 30A.

Further, the cleaning method according to the present embodiment is realized by the cleaning device system 20A described above. That is, in the cleaning method according to the present embodiment, the rotating body 32 is rotated relative to the pipe by passing a fluid through the pipe of the cleaning device system 20A, and the diameter of the rotating body 32 to the rotating body 32 is increased. This is a cleaning method for cleaning an object to be cleaned by bringing a rotating wire 34 into contact with the object to be cleaned while injecting a fluid outward in the direction.

Subsequently, the action and effect of this embodiment will be described. Also in the present embodiment, as in the first embodiment, the object to be cleaned is cleaned by the wire 34 while injecting the fluid outward in the radial direction of the rotating body 32 from the injection port 36 of the rotating rotating body 32. Can be done. As a result, as in the first embodiment, it is possible to simultaneously clean a wide area of the object to be cleaned by a simple method without any trouble.

Further, according to the present embodiment, since the water pipe wall (specifically, a plurality of water pipe walls) is used as the object to be cleaned, the purge cleaning and the cleaning of the keren are simultaneously performed on the plurality of water pipe walls. It can be carried out. As a result, the efficiency of the cleaning work of the water pipe wall can be improved. As a result, the work load of the cleaning worker can be reduced. As a result, the health condition of the cleaning worker can be maintained in good condition.

Further, according to the present embodiment, since the water pipe wall of the incinerator facility 10 (that is, the pipe for heat exchange) is used as the water pipe wall, the efficiency of the cleaning work of the incinerator facility 10 can be improved. .. This makes it possible to maintain a good health condition of the cleaning worker in that the chance of the cleaning worker being exposed to soot and dust during the cleaning work can be reduced. Specifically, the present embodiment is preferably applied to a heat exchange pipe used in an incinerator, an air preheater, or the like of an incinerator 10.

Further, also in the present embodiment, a fluid is used as a driving source for rotating the rotating body 32, and the fluid after being subjected to the rotation of the rotating body 32 is effectively used as a "purge cleaning fluid". Therefore, the configuration of the cleaning device 30A can be simplified.

Further, also in the present embodiment, since the rotating body 32 is rotated by the fluid, the cleaning device can be self-cleaned by the fluid. As a result, the maintenance cost of the cleaning device can be reduced. Further, also in the present embodiment, the fluid can be used to perform, for example, purge cleaning of the groove 33a-1 and the injection port 36, and purge cleaning of the inside of the pipe, so that the rotation function of the cleaning device can be maintained and the purge function (purge function). It is also possible to maintain the fluid purging function) toward the outside.

Further, according to the present embodiment, since the moving device 80 is provided, it is possible to clean the object to be cleaned while moving the rotating body 32 in the extending direction of the pipe. As a result, it is possible to clean a wide range of the object to be cleaned as compared with the case where the moving device 80 is not provided. Further, according to this configuration, even when the height of the object to be cleaned is high, the rotating body 32 can be moved from below to above the object to be cleaned for cleaning. In addition, since a scaffolding at a high place is not required at the time of cleaning, the cleaning period can be shortened and the labor of cleaning workers can be reduced, which is economical. Further, since the cleaning period can be shortened, it is not necessary to stop the incinerator 10 for a long period of time. As a result, the number of cleanings per year can be increased without impairing economic efficiency (for example, cleaning can be performed several times or more per year). Specifically, the number of simple cleanings and regular cleanings can be increased. Further, since the number of cleanings can be increased, high cooling efficiency and heat exchange efficiency can be maintained.

Further, according to the present embodiment, since the moving device 80 moves the rotating body 32 by utilizing the magnetic force generated by the magnetic force generating body 81, the rotating body 32 can be moved by a simple configuration.

Further, according to the present embodiment, since the moving device 80 moves the rotating body 32 by utilizing the buoyancy generated by the buoyancy blade 40, the rotating body 32 can be easily moved.

Further, according to the present embodiment, since the runout suppressing device 100 is provided, it is possible to effectively prevent the pipe from swinging in the direction approaching the object to be cleaned. Thereby, the cleaning work can be easily performed.

In the above-described first and second embodiments, if only cleaning is performed, the cleaning device may be configured not to inject fluid. That is, in this case, the cleaning device may be configured so that the fluid after rotating the rotating body 32 does not inject outward in the radial direction of the rotating body 32. In this case, when the rotating body 32 is rotating, the cleaning device does not perform purge cleaning with a fluid but only cleans the cleaning with the wire 34. However, as described above, it is preferable that the cleaning device performs not only cleaning but also purge cleaning because it can simultaneously clean a wide area of the object to be cleaned.

In the present embodiment, the cleaning device system 20A may not be provided with the scaffolding 160. Even in this case, the same effects as described above can be obtained.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to such specific embodiments, and various modifications and modifications are made within the scope of the gist of the present invention described in the claims. It can be changed.

For example, in the first and second embodiments, a predetermined part of the incinerator 10 is used as the object to be cleaned, but the object to be cleaned of the above-described first and second embodiments is not limited to the incinerator 10. A predetermined part of a mechanical device other than the incinerator 10, a predetermined part of a structure, or the like can be used. Further, when a predetermined part of the incineration facility 10 is used as the object to be cleaned, the predetermined part is not limited to the one illustrated in the first embodiment and the second embodiment. As the object to be cleaned, for example, a refractory wall surface of the incinerator 10 can be used.

Further, in the first and second embodiments, the rotating body 32 having a plurality of blades 37 is used, but the present invention is not limited to this configuration. As another example, as the rotating body 32, a cylindrical member (cylindrical member) can be used instead of the plurality of blades 37.

A slit or a hole as an injection port 36 is provided on the outer peripheral surface of the cylindrical member. By adjusting the opening direction of the injection port 36 (for example, by slightly directing the opening direction of the injection port 36 toward the tangential side of the outer peripheral surface of the cylindrical member), the fluid is injected from the injection port 36 of the cylindrical member. It is possible to rotate relative to the pipe by using the change in momentum at the time of operation. Further, the fluid after being subjected to the rotation of the cylindrical member is then injected from the injection port 36 toward the outside in the radial direction.
