Description

  The present invention relates to a heating device that can be used for heating piping and the like, and more particularly, to a heating device that uses wind power. The heating device of the present invention includes a heating device that can be substantially regarded as the heating device.

  In thermal power plants, factories, etc., in order to prevent water from freezing at low temperatures, so-called steam tracing and heater tracing, in which steam piping and a heater are wound around the outer wall surface of the water piping, are generally performed. . In thermal power plants, oil storage bases, etc., steam traces and heater traces are applied to storage tanks, supply pipes and the like to prevent the solidification of crude oil and oil and to ensure fluidity.

  It goes without saying that effective use of energy and reduction of energy consumption are important, as well as effective use of energy and reduction of energy consumption for steam, etc. used for heating the above water piping and fuel supply piping. Various initiatives that lead to

  For example, in a thermal power plant, extracted air (waste steam) generated when a steam turbine is driven is used as a heating heat source. In addition, a steam supply device that detects the atmospheric temperature or the ambient temperature, calculates the minimum steam trap inlet pressure required for the steam supply destination, adjusts the supply steam pressure to the minimum pressure, and reduces the amount of heated steam is also proposed. (For example, refer to Patent Document 1).

  With respect to heater tracing, a method has been proposed in which a generator is driven using the kinetic energy of a fluid flowing in a pipe and the generated electricity is used as a power source for the heater (see, for example, Patent Document 2).

Japanese Patent No. 5052330 JP-A-2005-213809

  For effective use of energy, it is conceivable to use natural energy instead of steam or electricity. For example, a method of using electricity generated by using solar power generation, wind power generation, or the like as a power source of a heater can be considered. These are useful methods and are technically established and can be introduced relatively easily, but the equipment introduction cost is high.

  It is desirable that the method of using natural energy for heating pipes is a method that does not use steam or electricity at all. However, even if the method uses less steam or electricity, the utility value is high and simple. Development of a device that is inexpensive and easy to install is awaited.

  An object of the present invention is to provide a heating device that uses wind power, is inexpensive with a simple configuration, and can efficiently heat an object to be heated.

The present invention includes a windmill that receives and rotates wind, a rotating body that is connected to and rotated by the windmill, and a fixed body that is attached to a heated portion, and the windmill and the rotating body are rotation transmitting means. The rotating body is slidably attached to the fixed body, the frictional heat generated with the rotation of the rotating body is transmitted to the heated portion via the fixed body, and It is a heating apparatus characterized by heating a heating part.

  This heating apparatus is configured to rotate a rotating body using wind power, generate frictional heat by bringing the rotating body and a fixed body into contact with each other, and heat a heated portion with the frictional heat. Therefore, the apparatus configuration is very simple and can be introduced at low cost. Moreover, since this heating apparatus directly converts kinetic energy into frictional heat, there is very little energy conversion loss, and wind energy can be used efficiently.

  When the windmill and the rotating body are connected via a rotation transmission means, for example, a gear device, energy loss is increased by the amount of the gear device interposed, but on the other hand, the flexibility of the windmill installation location, windmill configuration, etc. is large. Therefore, it becomes possible to efficiently heat the object to be heated by installing the windmill in a suitable place.

  Further, in the present invention, the heated portion is a pipe in which a fluid flows inside, and a steam trace pipe is attached to an outer wall surface, and the fixed body is attached so as to cover the pipe and the steam trace pipe. A fixed cylindrical member, and the rotating body is a rotating cylindrical member that is slidably attached to the outer peripheral surface of the fixed cylindrical member, the fixed cylindrical member, the pipe, and the steam trace pipe; The space is filled with a filler having excellent thermal conductivity.

  According to the present invention, the heating device can be attached to and used on a water pipe or the like that has been subjected to steam tracing, so that the water pipe or the like can be heated as a steam tracing complementing device. This heating device used in such a manner can reduce steam consumption if the wind blows, and water pipes and the like continue to be heated by steam tracing even when the wind does not blow. It can be said that it is a practical device.

  Further, in the present invention, instead of the steam trace pipe, a linear heater is attached to an outer wall surface of the pipe, and the fixed cylindrical member is attached so as to cover the pipe and the heater, and the fixed cylindrical member and the pipe And a heater is filled with a filler having excellent thermal conductivity.

  The heating apparatus can be suitably used for a water pipe or the like traced by a linear heater, similarly to a water pipe or the like subjected to steam tracing.

  Moreover, in this invention, the to-be-heated part covered with the said fixed body is equipped with a heat transfer promotion means inside, It is characterized by the above-mentioned.

  Heat transfer facilitating means inside the water pipe or the like covered with a fixed body that generates frictional heat, for example, a static mixer that provides fins that increase the heat transfer area on the inner wall surface, or promotes mixing of water flowing inside By attaching the, frictional heat can be efficiently transmitted to a water pipe or the like.

  ADVANTAGE OF THE INVENTION According to this invention, the heating apparatus which can heat a to-be-heated target object efficiently can be provided cheaply with simple structure using wind power.

It is a block diagram of the heating apparatus 1 of 1st Embodiment of this invention. It is principal part sectional drawing of the heating apparatus 1 of FIG. 1 provided with the rotary body 22 comprised with the laminated material. It is a block diagram of the heating apparatus 2 of 2nd Embodiment of this invention. It is a schematic diagram for demonstrating the structure of the heating apparatus 3 of 3rd Embodiment of this invention. It is a schematic diagram for demonstrating the structure of the heating apparatus 4 of 4th Embodiment of this invention.

  FIG. 1 is a configuration diagram of a heating device 1 according to a first embodiment of the present invention. Hereinafter, although the heating apparatus 1 which concerns on this invention is demonstrated using the heating apparatus 1 attached to the water piping 101, the use place of the heating apparatus 1 which concerns on this invention is limited to water piping is not.

  The heating device 1 is a device that directly converts wind energy into heat energy, and heats the water 105 that circulates in the water pipe 101 with the heat energy. The wind turbine 11 rotates by receiving wind. The rotating body 21 is connected to the windmill 11 and rotates, and the stationary body 31 is attached to the water pipe 101 which is a heated portion.

  The windmill 11 includes eight rectangular plate-shaped blades 14 having the same shape, and the blades 14 are radially fixed to the outer peripheral surface 24 of the rotating body 21. More specifically, each blade 14 is approximately 30 ° with respect to the cylindrical rotating body 21 with one side in the longitudinal direction parallel to the central axis of the rotating body 21 and with respect to the outer peripheral surface 24 of the rotating body 21. Installed at an angle. The eight blades 14 are arranged at equal intervals in the same manner.

  In the present embodiment, the windmill 11 has eight blades 14, but the number of blades is not limited to a specific number. In this embodiment, the shape of the blade 14 is rectangular, and these are attached with an inclination of about 30 ° with respect to the outer peripheral surface 24 of the rotating body 21. The angle is not limited to a specific one. If necessary, the wind turbine 11 may be any one that can easily receive wind and rotate efficiently, including the size of the blade 14.

  The blade 14 is made of a material having a small specific gravity and a low thermal conductivity. It becomes easy to rotate by making the blade 14 light. Further, if the blade 14 is lightened, the weight of the heating device 1 is reduced, and the support frame for supporting the water pipe 101 to which the heating device 1 is attached can be downsized.

  Further, the heat radiation is reduced by forming the blade 14 with a material having low thermal conductivity. The windmill 11 is a part that rotates by receiving wind, and the windmill 11 does not generate heat. However, since the rotating body 21 connected to the windmill 11 generates heat as described later, if the thermal conductivity of the blade 14 is high, Heat generated in the rotating body 21 is easily released through the blade 14. In particular, since the blade 14 fixed to the rotating body 21 has the same form as the fin, the heat radiation area increases.

  From the above, the blade 14 is preferably formed of a synthetic resin having a low thermal conductivity, a fiber reinforced plastic having a low thermal conductivity, or a coating material obtained by coating a metal material with a synthetic resin having a low thermal conductivity.

  The rotating body 21 is a cylindrical member that rotates in contact with the fixed body 31 and generates frictional heat. Since the rotating body 21 is a member that generates frictional heat, it can be rephrased as a rotating friction plate. The blade 14 is fixed to the outer peripheral surface 24 of the rotating body 21. The rotating body 21 covers the fixed body 31 and is attached so that the inner peripheral surface 25 is slidable with respect to the outer peripheral surface 32 of the fixed body 31. That is, the inner peripheral surface 25 of the rotating body 21 and the outer peripheral surface 32 of the fixed body 31 are both sliding surfaces.

  The material and surface state of the inner peripheral surface 25 of the rotating body 21 greatly affect the amount of frictional heat generated. From the viewpoint of increasing the amount of generated frictional heat, a material having a large sliding frictional resistance with respect to the outer peripheral surface 32 of the fixed body 31 is preferable. The inner peripheral surface 25 of the rotator 21 may be surface-treated to increase the sliding friction resistance, and the inner peripheral surface 25 of the rotator 21 is preferably less likely to wear and change in surface state.

  It is preferable to take measures to suppress heat dissipation on the outer peripheral surface 24 of the rotating body 21. Specifically, for example, there is a method of covering the outer peripheral surface 24 with a member having low thermal conductivity. The rotating body 21 is not necessarily formed by a single member, and for example, a laminated material in which two members are bonded may be used.

  FIG. 2 is a cross-sectional view of a main part of the heating device 1 including the rotating body 22 made of a laminated material. The rotating body 22 shown in FIG. 2 has a three-layer structure, and the outer layer material 26 and the inner layer material 27 are bonded so that an air layer is formed as an intermediate layer 28 between the outer layer material 26 and the inner layer material 27. Laminated material. The outer layer material 26 is formed of a synthetic resin material having a low thermal conductivity, and covers the inner layer material 27 so that an air layer is formed. The inner layer material 27 is made of a metal material and is subjected to a surface treatment for increasing the sliding frictional resistance on the inner peripheral surface 25.

  When the rotating body is formed of a plurality of laminated materials, the innermost member uses a member with high sliding friction resistance and excellent wear resistance, and the outer member has thermal conductivity. It is preferable to use a small member. When using a laminated material, as long as the member which comprises each layer is joined firmly, as shown in FIG. 2, you may provide a clearance gap and an air layer between each layer. In addition, by providing a gap and an air layer positively between the inner layer material 27 and the outer layer material 26 and causing them to act as a heat insulating material and a heat insulating layer, heat radiation to the outside can be suppressed.

  Since the inner peripheral surface 25 of the rotating bodies 21 and 22 slides with respect to the outer peripheral surface 32 of the fixed body 31, there is a concern about wear due to long-time operation. For this reason, when the rotating body is formed of a laminated material, the inner layer material 27 may be formed easily, and when the inner peripheral surface 25 of the rotating body is worn, only the inner layer material 27 may be replaced.

  The joining method of the rotating body 21 and the blade 14 is not limited to a specific method. For example, a mounting seat is provided on the outer peripheral surface 24 of the rotating body 21 and the blade 14 is bolted, a method of welding and fixing the blade 14 to the outer peripheral surface 24 of the rotating body 21, or an outer layer material 26 of the rotating body 21 For example, a method of integrally forming the blade 14 and then joining the inner layer material 27 may be used.

  The fixed body 31 is a cylindrical member that cooperates with the rotating body 21 and generates frictional heat, and is formed of a member having excellent thermal conductivity and excellent wear resistance. Since the fixed body 31 is a member that generates frictional heat, it can be rephrased as a fixed friction plate. The wear resistance of the outer peripheral surface 32 of the fixed body 31 is preferably superior to the wear resistance of the inner peripheral surface 25 of the rotating body 21. As a result, the rotating body 21 is worn first as compared with the fixed body 31 even when it is worn with a long operation. Compared with the replacement of the fixed body 31, the replacement of the rotating body 21 is easy, so that the replacement work is facilitated.

  The outer diameter of the fixed body 31 is substantially the same as the inner diameter of the rotating body 21, and the rotating body 21 is slidably fitted into the fixed body 31 with almost no gap. On the other hand, the inner diameter of the fixed body 31 is a size that covers the water pipe 101 and the steam trace pipe 111 spirally wound around the outer wall surface of the water pipe 101 and a part of the inner peripheral surface 32 is in contact with them. .

  The fixed body 31 is attached so as to cover the water pipe 101 and the steam trace pipe 111, and the heat transfer cement 41 is filled in the gap. As is well known, the heat transfer cement 41 is a member that is soft before construction and excellent in heat transfer properties that hardens when dried. The heat transfer cement 41 is a representative example of a filler excellent in heat transfer properties. Instead of the heat transfer cement 41, a filler excellent in heat transfer properties may be used.

  The gap generated when the fixed body 31 is attached to the water pipe 101 should be as narrow as possible. The gap generated when the fixed body 31 is attached to the water pipe 101 can be filled with the heat transfer cement 41. However, since the heat transfer cement 41 also has a heat resistance in terms of heat transfer, the heat transfer cement is as much as possible. 41 should also be thin. Further, when the gap is filled with the heat transfer cement 41, if the air layer remains, the portion becomes a thermal resistance, so that the air layer does not remain.

  The fixing method of the fixed body 31 with respect to the water pipe 101 is not limited to a specific method, and it is sufficient that the fixed body 31 is firmly fixed without being rotated even when the rotating rotating body 21 rotates.

  The material and surface state of the fixed body 31 are preferably those having a large sliding friction resistance with respect to the inner peripheral surface 25 of the rotating body 21 from the viewpoint of increasing the amount of frictional heat generated, are not easily worn, and the surface state changes. Difficult ones are preferred. Similarly to the inner peripheral surface 25 of the rotating body 21, the outer peripheral surface 32 of the fixed body 31 may be surface-treated to increase the sliding friction resistance. In addition, from the viewpoint of transmission of frictional heat to the water pipe 101, the fixed body 31 preferably has a high thermal conductivity and a small thickness.

  The attachment method to the water piping 101 of the heating apparatus 1 is not limited to a specific method. For example, in a factory, the steam trace pipe 111 and the heating device 1 are attached to the water pipe 101 with the flanges attached to both ends, and the steam trace pipe 111 and the heating apparatus 1 are carried to the site and connected to the other water pipe 101 and the steam trace pipe 111. May be.

  The number of heating devices 1 to be attached to one water pipe 101 is not limited to one, and a plurality of heating devices 1 may be attached.

  When the heat of friction between the fixed body 31 and the water pipe 101 and the water 105 flowing through the pipe is poor while the frictional heat generated in the heating device 1 is large, the temperature of the fixed body 31 rises abnormally. . In order to prevent this state, it is necessary to improve heat transfer between the fixed body 31 and the water pipe 101 and the water 105 flowing through the pipe.

  Usually, since carbon steel, stainless steel, or the like is used for the water pipe 101, heat transfer between the fixed body 31 and the water pipe 101 and the water 105 flowing through the pipe is considered to be relatively good. The heat transfer between the fixed body 31 and the water pipe 101 and the water 105 flowing through the pipe is improved by providing heat transfer promoting means inside the water pipe 101 in the portion surrounded by the fixed body 31. Can do.

  Examples of the heat transfer promoting means include fins that increase the heat transfer area and static mixers that promote heat transfer. Specifically, fins are provided inside the portion of the water pipe 101 surrounded by the fixed body 31 to increase the heat transfer area. Or when the water 105 is always circulating in the water pipe 101, a static mixer is attached in the water pipe 101 to promote heat transfer. This is the same in other embodiments.

  Heating of the water pipe 101 equipped with the heating device 1 having the above-described configuration is performed as follows. The water pipe 101 is provided with a steam trace pipe 111 on the outer wall surface and a heat insulating material 115 for covering them. Similarly to the known steam trace, the steam trace pipe 111 is supplied with steam, The piping 101 and the water 105 in the piping are heated, and the drain is discharged from a steam trap (not shown).

  When the wind blows and the windmill 11 rotates, frictional heat is supplied to the water pipe 101 via the heating device 1. Along with this, steam consumption of the steam trace decreases. On the other hand, when the wind does not blow, only the steam trace functions and heats the water pipe 101. As described above, the heating device 1 shown in the present embodiment can be said to be a practical device that functions as a steam trace complementing device.

  FIG. 3 is a configuration diagram of the heating device 2 according to the second embodiment of the present invention. The same components as those of the heating device 1 of the first embodiment shown in FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof is omitted. Hereinafter, the warming device 2 according to the present invention will be described using the warming device 2 attached to the water pipe 101 as in the first embodiment. The water pipe 101 is not limited.

  The heating device 2 has the same basic configuration as the heating device 1 and directly converts wind energy into heat energy and heats the water pipe 101 and the water 105 in the water pipe 101 with this heat energy. is there.

  The heating device 2 includes a windmill 12 that receives and rotates the wind as in the heating device 1, a rotating body 23 that rotates in connection with the windmill 12, and a fixed body 31 that is attached to the water pipe 101 that is a heated portion. However, the windmill 12 and the rotating body 23 are separated, and these are connected via a gear device 51.

  The windmill 12 has eight rectangular flat blades 15 arranged radially with respect to the support shaft 16, and the support shaft 16 is erected vertically. The number, size, shape, and material of the blades 15 constituting the windmill 12 and the mounting angle of the blades 15 with respect to the support shaft 16 are not particularly limited, and they can easily receive wind and rotate efficiently. That's fine. In addition, since the windmill 12 is isolate | separated from the rotary body 23 unlike the windmill 11 of 1st Embodiment, it is not necessary to consider especially about the thermal radiation from the blade 15 considered with the windmill 11. FIG.

  The rotating body 23 is slidably attached to the fixed body 31 and functions as a rotating friction plate like the rotating bodies 21 and 22 to generate frictional heat. The rotating body 23 is different from the rotating bodies 21 and 22 shown in the first embodiment in that a spur gear 58 is attached to one end portion of the outer peripheral surface 24 instead of the wind turbine 12. For example, the configuration of the material and the like is the same as that of the rotating bodies 21 and 22.

  The gear device 51 includes a bevel gear, a spur gear, and the like, and includes an orthogonal shaft type speed increaser 53 that changes the rotation direction to an orthogonal direction and increases the rotation speed, and spur gears 57 and 58. The lower end of the support shaft 16 is connected to the vertical shaft 54 of the orthogonal shaft type gearbox 53, and the spur gear 57 is connected to the horizontal shaft 55 of the orthogonal shaft type gearbox 53. The spur gear 58 is attached to the outer peripheral surface 24 of the rotating body 23, and the spur gear 57 and the spur gear 58 mesh with each other.

  With the above configuration, the rotation of the windmill 12 is transmitted to the rotating body 23 via the gear device 51. The gear device 51 is not limited to the gear device shown in the present embodiment, and it is preferable that the gear device 51 can transmit the rotation of the windmill 12 to the rotating body 23 as much as possible. In general, since the number of gears is large and the loss in transmission increases as the mechanism becomes complicated, a simple gear device is preferable. Note that the rotation of the windmill 12 may be transmitted to the rotating body 23 using another rotation transmission device instead of the gear device 51.

  Since the operation, action, effect, installation procedure, and the like of the warming device 2 are basically the same as those of the warming device 1, description thereof will be omitted. The windmill shown in the second embodiment is a windmill 12 in which eight rectangular flat blades 15 are arranged radially and orthogonally to the support shaft 16, but the windmill is limited to this type of windmill. Is not to be done. For example, a windmill used in wind power generation such as a propeller-shaped horizontal axis windmill or an S-shaped vertical axis windmill can be used, and the gear unit 51 may be configured according to the type of the windmill.

  When the heating device 1 of the first embodiment is compared with the heating device 2 of the second embodiment, the heating device 2 transmits the rotation of the windmill 12 to the rotating body 23 using the gear device 51. Energy loss associated with is inevitable. For this reason, although the heating apparatus 1 is superior in terms of energy efficiency, the heating apparatus 2 has a high degree of freedom in installing the windmill 12. Further, the warming device 2 is more advantageous where the wind direction changes frequently. From the above, the heating device 1 of the first embodiment can be suitably used in a place where the wind direction is constant, and the heating device 2 of the second embodiment can be suitably used in other places.

  In 1st and 2nd embodiment, although the example which attaches the heating apparatuses 1 and 2 to the water piping 101 with which the steam trace piping 111 was mounted was shown, it replaced with a steam trace and a linear electric heater, for example, a sheathed heater, is shown. The heating devices 1 and 2 can be attached and used in the same manner with respect to the water pipe 101 with which it was mounted. In addition to the water pipe 101, the heating devices 1 and 2 can be attached to a fuel supply pipe or the like.

  FIG. 4 is a schematic diagram for explaining the configuration of the heating device 3 according to the third embodiment of the present invention. The same components as those of the heating devices 1 and 2 shown in FIGS. 1 to 3 are denoted by the same reference numerals and description thereof is omitted. Although the heating device 3 of the third embodiment is attached to the oil tank 121, the usage destination of the heating device 3 is not limited to the oil tank 121.

  The heating device 3 is the same as the heating devices 1 and 2 and directly converts wind energy into heat energy, and heats the oil 125 stored in the oil tank 121 using this heat energy.

And a rotating body 23 that is connected to and rotates, and a fixed body 31 that is attached to the side peripheral surface of the oil tank 121.

  Although the windmill 13 is a propeller-shaped horizontal axis windmill, the model of a windmill is not specifically limited like the heating apparatus 2 of 2nd Embodiment. The fixed body 31 is fixed to the side peripheral surface 122 of the cylindrical oil tank without a gap, and the rotating body 23 covers the fixed body 31 and is slidably attached to the fixed body 31. The windmill 13 and the rotating body 23 are connected to each other via an orthogonal shaft type gearbox 53 and spur gears 57 and 58 constituting a gear device 51.

  The oil tank 121 includes an electric heater 123 and a temperature controller 124, and holds the oil 125 in the oil tank 121 at a predetermined temperature. The heating device 3 supplements the electric heater 123 to heat the oil 125 with frictional heat generated by receiving wind. Thus, the heating device 3 can be used for heating the tank and the device in addition to the piping.

  FIG. 5 is a schematic diagram for explaining the configuration of the heating device 4 according to the fourth embodiment of the present invention. The same components as those of the heating devices 1, 2, and 3 shown in FIGS. 1 to 4 are denoted by the same reference numerals and description thereof is omitted. Although the heating device 4 incorporated in the heat medium supply device 131 is shown in the fourth embodiment, the application destination of the heating device 4 is not limited to heating of the heat medium.

  Although the name of the heating device 4 is a heating device, it basically has the same configuration as the heating devices 1, 2, and 3, and directly converts wind energy into thermal energy. The inside heat medium 134 is heated.

  As with the heating device 2, the heating device 4 includes a windmill 12 that receives and rotates wind, a rotating body 29 that rotates directly connected to the support shaft 16 of the windmill 12, and a top surface of a heating tank 132 that is a heated portion. And a fixed body 35 attached to 133.

  The fixed body 35 has a flat plate shape and is fixed to the outer wall of the ceiling surface 133 of the heating tank without a gap. The rotating body 29 is also a flat disk and is slidably attached to the fixed body 35. The rotating body 29 and the fixed body 35 are members corresponding to the rotating body 21 and the fixed body 31 of the heating device 1 and function as a rotating friction plate and a fixed friction plate. The rotary body 29 and the fixed body 35 are different in shape from the rotary body 21 and the fixed body 31 of the heating device 1 and the like, but the material, specific gravity, heat transfer, sliding frictional resistance of the sliding surface, etc. are heated. It can be considered in the same manner as the rotating body 21 and the fixed body 31 of the device 1 or the like.

  The heat medium supply device 131 includes a heating tank 132, a supply pump 135, a heat medium supply line 136, and a heat medium return line 137. The heating tank 132 has a heat medium 134 therein, and the heat medium 134 in the heating tank 132 is adjusted to a predetermined temperature via a steam heating device 138 using steam as a heat source. It is supplied to the user through the supply line 136. The heating device 4 complements the steam heating device 138.
