Description

  Embodiments of the present invention relate to a horizontal inflow condenser.

  In a horizontal exhaust type turbine system such as an axial flow type or a side flow type, the steam exhausted in the horizontal direction from the turbine (hereinafter also simply referred to as “exhaust steam”) is recovered without changing its flow direction. Introduce into water container. For this reason, it has the advantage that the pressure loss of exhaust steam can be made small compared with a lower exhaust type turbine system.

  In a condenser (horizontal inflow condenser) used in a horizontal exhaust turbine system, an upper main body of the condenser is connected to the front or side of a turbine exhaust chamber. Some of these horizontal inflow condensers have heat transfer tubes arranged at substantially the same height as the turbine shaft, and exhaust steam is linearly introduced to the heat transfer tubes along the horizontal direction to condense.

  However, if exhaust steam is to be introduced to the heat transfer pipe without changing the flow direction, it is difficult to place the heat transfer pipe at the same height as the turbine shaft due to the height limitation of the siphon limit of the circulating water pump. There is. In that case, the heat transfer tube is installed below the height of the turbine shaft, and the flow direction of the exhaust steam is changed from the horizontal direction to the vertical direction in the upper main body of the condenser. However, by changing the flow direction of the exhaust steam, there is a problem that a vortex flow is generated in the upper body portion of the condenser and the pressure loss increases.

  In order to reduce the pressure loss, a structure is considered in which the upper main body of the condenser is shaped like a long duct, and the exhaust steam is introduced into the heat transfer tubes after the flow direction of the exhaust steam is gently changed. It is done. However, in this case, the size of the condenser increases, and there is a possibility that the condenser cannot be installed in the plant building.

  The problem to be solved by the present invention is to provide a horizontal inflow condenser capable of reducing pressure loss while avoiding an increase in size.

  The horizontal inflow type condenser according to the embodiment includes an upper body part into which exhaust steam exhausted in a horizontal direction from a turbine flows from a side surface, and an exhaust gas that is provided below the upper body part and circulates in the upper body part.

(First embodiment)
With reference to FIG. 1A, FIG. 1B, and FIG. 1C, the horizontal inflow type condenser 1 which concerns on 1st Embodiment is demonstrated.

  The horizontal inflow condenser 1 is installed in the upper main body 2, the lower main body 3 provided below the upper main body 2, and the lower main body 3 to cool the exhaust steam. And a heat transfer tube 4.

  Exhaust steam exhausted in the horizontal direction from a turbine (not shown) flows into the upper main body 2 from the side surface. More specifically, an inlet 6a is provided on the side surface of the upper body 2 and the upper body 2 is connected to the turbine exhaust chamber via the inlet 6a. For this reason, the exhaust steam of the turbine flows into the horizontal inflow condenser 1 from the inlet 6a.

  Exhaust steam flowing through the upper main body 2 flows into the lower main body 3 from above. The exhaust steam flowing into the lower main body 3 is condensed by the heat transfer tube 4 to become liquid water. The lower main body 3 also functions as a water storage tank in which liquid water temporarily accumulates. As shown in FIGS. 1A and 1C, connection portions 3 a are provided on two opposing side surfaces of the lower main body portion 3. The lower main body 3 is connected to a water intake channel, a water discharge channel or the like through the connection unit 3a.

  Next, the configuration of the upper main body 2 will be described in more detail.

  As shown in FIG. 1A, the upper body portion 2 includes an upper body body portion 5, a first upper body end plate 6, and a second upper body end plate 7.

  As shown in FIG. 1C, the upper main body 5 includes a curved plate 5a formed by bending a plate-like member, and a flat bottom plate extending from the lower end of the curved plate 5a toward the lower main body 3. 5b.

  The first upper body end plate 6 closes one end (the left end in FIG. 1A) of the upper body body 5. The first upper body end plate 6 is provided with an inlet 6a through which exhaust steam from the turbine flows. As shown in FIG. 1C, the inflow port portion 6a is formed in an annular shape along the outline of the curved plate 5a.

  As shown in FIG. 1C, the first upper main body end plate 6 has wall portions 6b on the left and right sides below the inflow port portion 6a. The wall portion 6b is a part of the first upper body end plate 6 and is provided between the edge portion of the inflow port portion 6a and the bottom plate 5b.

  The second upper body end plate 7 closes the other end (the right end in FIG. 1A) of the upper body trunk 5. As shown in FIG. 1B, the second upper body end plate 7 is provided so as to face the inflow port portion 6a. The first upper body end plate 6 and the second upper body end plate 7 may be planar.

  As shown in FIGS. 1A and 1C, the upper main body 2 has a semi-cylindrical shape. Thereby, the structural strength with respect to the external pressure load applied to the upper body part 2 as the exhaust steam condenses is secured.

  A first rectifying plate 8 is provided inside the upper main body 2. As shown in FIG. 1B, the first rectifying plate 8 covers a corner portion C formed by the curved plate 5 a of the upper body trunk 5 and the second upper body end plate 7. An angle β formed by the first rectifying plate 8 and the second upper body end plate 7 is larger than an angle α formed by the curved plate 5 a and the second upper body end plate 7.

  The edge part of the 1st baffle plate 8 is connected to the upper side main body trunk | drum 5 and the 2nd upper side main body end plate 7, as shown to FIG. 1A. Moreover, as shown in FIG. 1B and FIG. 1C, the 1st baffle plate 8 is provided diagonally with respect to the inflow direction of the exhaust gas of a turbine so that the opening surface of the inflow port part 6a may be opposed. In this specification, the inflow direction of the exhaust steam means the axial direction of the turbine.

  When the first rectifying plate 8 is not provided, the angle α of the corner C is steep (for example, close to 90 °), so that the flow direction of the exhaust steam changes abruptly. A stagnation occurs and a vortex is generated, increasing the pressure loss. On the other hand, when the first rectifying plate 8 is provided, the angle β is larger than the angle α of the corner C, and the change in the flow direction of the exhaust steam is gradual. And pressure loss can be reduced.

  In the horizontal inflow condenser 1 according to the first embodiment, since the first rectifying plate 8 is provided, the exhaust steam flowing into the upper main body 2 from the inlet 6a is the first. The flow direction is gently changed along the current plate 8 and the second upper body end plate 7, and the flow is introduced into the lower body 3. Thereby, the eddy current which generate | occur | produces in the upper side main-body part 2 can be reduced, and the pressure loss of exhaust steam can be made small. As a result, the performance of the horizontal inflow condenser can be improved. Moreover, since the 1st baffle plate 8 is provided in the upper side main-body part 2, the size of a horizontal inflow type condenser is not enlarged.

  As described above, according to the first embodiment, it is possible to provide a horizontal inflow condenser that can reduce pressure loss while avoiding an increase in size.

(Second Embodiment)
Next, with reference to FIG. 2A and FIG. 2B, the horizontal inflow type condenser 1A which concerns on 2nd Embodiment is demonstrated.

  In the horizontal inflow type condenser 1 according to the first embodiment, a space where the exhaust steam pool is generated remains in the abutting portion where the first rectifying plate 8 abuts on the second upper body end plate 7.

  Therefore, the horizontal inflow condenser 1A according to the present embodiment further includes a second rectifying plate 9 in addition to the components of the horizontal inflow condenser 1 according to the first embodiment. By providing the second rectifying plate 9, the change in the flow direction of the exhaust steam becomes more gradual, so that the generation of vortex can be further suppressed.

  The second rectifying plate 9 is provided so that the first rectifying plate 8 covers the contact portion D where the second rectifying plate 8 contacts the second upper body end plate 7 from the inside. As shown in FIG. 2B, the angle γ formed by the second rectifying plate 9 and the first rectifying plate 8 is larger than the angle β formed by the first rectifying plate 8 and the second upper body end plate 7. .

  The edge part of the 2nd baffle plate 9 is connected to the 1st baffle plate 8, the upper side main body trunk | drum 5, and the 2nd upper side main body end plate 7, as shown to FIG. 2A. Further, as shown in FIG. 2B, the second rectifying plate 9 is provided obliquely with respect to the inflow direction of the exhaust steam of the turbine so as to face the opening surface of the inflow port portion 6a.

  In the horizontal inflow condenser 1A according to the second embodiment, since the first rectifying plate 8 and the second rectifying plate 9 are provided, the exhaust gas flowing into the upper main body portion 2 from the inflow port portion 6a. The steam gradually changes the flow direction along the first rectifying plate 8, the second rectifying plate 9 and the second upper body end plate 7, and is introduced into the lower body portion 3. Thereby, the eddy current which generate | occur | produces in the upper side main-body part 2 can be reduced, and the pressure loss of exhaust steam can be made small. Moreover, since the 2nd baffle plate 9 is provided in the inside of the upper side main-body part 2 with the 1st baffle plate 8, the size of a horizontal inflow type condenser does not enlarge.

  As described above, according to the second embodiment, it is possible to provide a horizontal inflow condenser that can reduce pressure loss while avoiding an increase in size.

(Third embodiment)
Next, with reference to FIG. 3A, FIG. 3B, and FIG. 3C, the horizontal inflow type condenser 1B which concerns on 3rd Embodiment is demonstrated.

  The speed of the exhaust steam that flows into the upper main body 2 from the inlet 6a and flows along the first rectifying plate 8 and the second upper main body end plate 7 is high. Further, the exhaust vapor hitting the first rectifying plate 8 and the second upper body end plate 7 diffuses in a direction orthogonal to the inflow direction. As a result, the flow of the exhaust vapor is disturbed and the pressure loss increases.

  Therefore, the horizontal inflow condenser 1B according to the present embodiment further includes a plurality of third rectifying plates 10 in addition to the components of the horizontal inflow condenser 1 according to the first embodiment.

  As shown in FIGS. 3A and 3B, the third rectifying plate 10 is provided on the first rectifying plate 8 at a predetermined interval so as to extend along the inflow direction of the exhaust steam from the turbine. . As shown in FIG. 3C, the third rectifying plate 10 extends vertically downward from the lower surface (inner side surface) of the first rectifying plate 8. The structural strength of the first rectifying plate 8 can be improved by providing the third rectifying plate 10.

  In the horizontal inflow condenser 1 </ b> B according to the third embodiment, a first rectifying plate 8 and a plurality of third rectifying plates 10 are provided in the upper main body 2. For this reason, the exhaust steam that has flowed into the upper main body 2 is introduced into the lower main body 3 while being prevented from diffusing in the direction orthogonal to the inflow direction. Thereby, pressure loss can be made small. As a result, the exhaust steam can be efficiently condensed, and the performance of the horizontal inflow condenser can be improved.

(Fourth embodiment)
Next, with reference to FIG. 4A, FIG. 4B, and FIG. 4C, the horizontal inflow type condenser 1C which concerns on 4th Embodiment is demonstrated.

  As described with reference to FIG. 1C in the first embodiment, wall portions 6 b are provided on the left and right sides of the lower side of the first upper body end plate 6. For this reason, when the exhaust steam flows into the upper main body 2, the cross-sectional area of the exhaust steam rapidly increases. Therefore, the exhaust vapor that has passed through the lower edge of the inlet portion 6a and has flowed into the upper body portion 2 flows into the space defined by the wall portion 6b and the bottom plate 5b. As a result, an eddy current is generated in the space from the wall 6b to the upper side of the heat transfer tube 4, and the exhaust steam accumulates in the space, which may reduce the performance of the condenser.

  Accordingly, the horizontal inflow condenser 1C according to the present embodiment further includes a fourth rectifying plate 11 in addition to the components of the horizontal inflow condenser 1 according to the first embodiment.

  The 4th baffle plate 11 is provided in the upper side main-body part 2, as shown to FIG. 4A and 4B. For example, the fourth rectifying plate 11 is a plate-like member having a triangular planar shape, the first side portion is connected to the wall portion 6b, the second side portion is connected to the skirt plate 5b, The sides are open. In addition, in FIG. 4B, although the 4th baffle plate 11 has covered the upper part of the heat exchanger tube 4 by the side of a turbine (inlet part 6a side), it does not need to cover.

  More specifically, as shown in FIG. 4B, the fourth rectifying plate 11 extends from the wall portion 6 b to the inner side and the lower side of the upper body portion 2 when viewed in a longitudinal section parallel to the inflow direction of the exhaust steam. It is inclined towards. Moreover, the inner surface of the 4th baffle plate 11 has faced the central axis line of the inflow port part 6a, as shown to FIG. 4C.

  By providing the fourth rectifying plate 11, the cross-sectional area of the exhaust steam gradually increases when the exhaust steam flows into the upper body 2. For this reason, it is suppressed that exhaust steam is caught in the space defined by the wall part 6b and the skirt board 5b, generation | occurrence | production of a vortex | eddy_current can be reduced, and pressure loss can be reduced. Furthermore, the efficiency of heat exchange by the heat transfer tube 4 on the turbine side can be improved, and the performance of the horizontal inflow condenser can be improved.

(Fifth embodiment)
Next, with reference to FIG. 5A and FIG. 5B, the horizontal inflow type condenser 1D which concerns on 5th Embodiment is demonstrated.

  As explained in the fourth embodiment, when the exhaust vapor passes through the inlet 6 a and flows into the upper main body 2, the cross-sectional area of the exhaust vapor rapidly expands at the lower part of the first upper main body end plate 6. . When the exhaust steam passes through the inlet 6a and flows into the upper main body 2, the lower part of the exhaust steam tends to flow downward. However, since the flow velocity of the exhaust steam is high, the downward flow is separated from the main flow. For this reason, the separated flow forms a vortex in the space on the turbine side (first upper body end plate 6 side) in the upper space of the lower body portion 3 (the space above the heat transfer tube 4). As a result, the exhaust steam convects in the space above the heat transfer tube 4 arranged on the turbine side, and the condensation efficiency of the heat transfer tube 4 may be reduced, thereby reducing the performance of the horizontal inflow condenser.

  Therefore, the horizontal inflow condenser 1D according to the fifth embodiment further includes a fifth rectifying plate 12 in addition to the components of the horizontal inflow condenser 1 according to the first embodiment.

  As shown in FIGS. 5A and 5B, the fifth rectifying plate 12 is a plate-like member having a rectangular planar shape, and is provided on the inflow port 6 a side from the center inside the upper main body portion 2. As shown in FIG. 5A, both end portions of the fifth rectifying plate 12 are connected to the bottom plate 5 b of the upper main body trunk portion 5. The fifth rectifying plate 12 is provided obliquely with respect to the inflow direction of the exhaust vapor so as to face the opening surface of the inflow port portion 6a, and the lower main body portion 3 transmits the exhaust vapor flowing in from the inflow port portion 6a. To guide.

  The flow direction of the lower part of the exhaust steam flowing in the upper body part 2 in the horizontal direction is changed to the lower body part 3 by the fifth rectifying plate 12 without generating vortex. Thereby, it can suppress that the convection of exhaust steam generate | occur | produces in the space above the heat exchanger tube 4 arrange | positioned at the turbine side. As a result, the condensation efficiency of the heat transfer tubes 4 arranged on the turbine side is improved, and the performance of the horizontal inflow condenser can be improved.

<First Modification of Fifth Embodiment>
FIG. 6A shows a partial cross-sectional view of a horizontal inflow condenser according to a first modification of the fifth embodiment. As shown in FIG. 6A, the fifth rectifying plate 12 is provided with a passage portion 12a through which the exhaust steam passes in the horizontal direction in order to reduce the pressure loss of the exhaust steam. The passage portion 12a is, for example, a slit that penetrates the fifth rectifying plate 12 and extends in the longitudinal direction.

  It should be noted that a plurality of small slits are provided in the fifth rectifying plate 12 rather than providing one large slit as the passage portion 12a in the fifth rectifying plate 12 so that the structural strength of the fifth rectifying plate 12 is not significantly reduced. It is preferable to provide it. In addition, a slit corresponding to the passage portion 12a may be formed by providing two rectifying plates in parallel at an interval.

  According to the present modification, the flow of the lower part of the exhaust steam flowing into the upper body part 2 can be changed toward the lower body part 3 while suppressing an increase in pressure loss due to the fifth rectifying plate 12. .

<Second Modification of Fifth Embodiment>
FIG. 6B is a partial cross-sectional view of a horizontal inflow condenser according to a second modification of the fifth embodiment. As shown in FIG. 6B, the fifth rectifying plate 12 is provided with a passage portion 12 a through which exhaust steam passes, and a sixth rectifying plate 13 is provided apart from the fifth rectifying plate 12. The fifth rectifying plate 12 may not be provided with the passage portion 12a.

  Similar to the fifth rectifying plate 12, the sixth rectifying plate 13 is a plate-like member having a rectangular planar shape, and is provided on the inflow port portion 6 a side from the center inside the upper main body portion 2. Both end portions of the sixth rectifying plate 13 are connected to the bottom plate 5 b of the upper main body body 5. The sixth rectifying plate 13 is provided obliquely with respect to the inflow direction of the exhaust vapor so as to face the opening surface of the inflow port portion 6a, and the lower main body portion 3 receives the exhaust vapor flowing from the inflow port portion 6a. To guide.

  As shown in FIG. 6B, it is preferable that the sixth rectifying plate 13 is provided at a lower height than the passing portion 12a so as not to block the passing portion 12a of the fifth rectifying plate 12. Moreover, it is preferable that the 6th baffle plate 13 is provided under the 5th baffle plate 12 so that inclination may become steeper than the 5th baffle plate 12, as shown to FIG. 6B.

  By providing the sixth rectifying plate 13, the flow of the lower part of the exhaust steam flowing into the upper main body 2 is directed toward the lower main body 3 compared to the case where only the fifth rectifying plate 12 is provided. The flow will be changed more. Thereby, according to this modification, the convection of the exhaust steam in the space above the heat transfer tube on the turbine side can be further suppressed, and the performance of the horizontal inflow condenser can be further improved.

(Sixth embodiment)
Next, with reference to FIG. 7A and FIG. 7B, the horizontal inflow type condenser 1E which concerns on 6th Embodiment is demonstrated. One of the differences between the sixth embodiment and the first embodiment is the shape of the second upper body end plate. In the present embodiment, the first rectifying plate 8 is not provided.

  The second upper body end plate 7A according to the sixth embodiment closes the other end of the upper body barrel 5 as shown in FIGS. 7A and 7B. Further, as shown in FIG. 7B, the second upper body end plate 7A is curved so as to protrude outward when viewed in a longitudinal section parallel to the inflow direction of the exhaust steam. Preferably, the second upper body end plate 7A is curved to draw a smooth curve as shown in FIG. 7B.

  Since the second upper body end plate 7A is curved so as to protrude outward as described above, the exhaust steam flowing into the upper body portion 2 flows in the flow direction along the second upper body end plate 7A. Is gradually introduced into the lower body 3. Thereby, the eddy current which generate | occur | produces in the upper side main-body part 2 can be reduced, and the pressure loss of exhaust steam can be made small. Therefore, the performance of the horizontal inflow type condenser can be improved. Further, the size of the horizontal inflow condenser is not increased.

  Therefore, according to the sixth embodiment, it is possible to provide a horizontal inflow condenser that can reduce pressure loss while avoiding an increase in size.

  Furthermore, according to the sixth embodiment, since the shape of the end plate of the upper main body 2 is a bonnet type, the structural strength of the upper main body 2 can be improved. As a result, it is possible to reduce the number of reinforcing members provided in the upper main body 2 and to provide a horizontal inflow condenser having a simpler structure.

  According to at least one embodiment described above, it is possible to provide a horizontal inflow condenser that can reduce pressure loss while avoiding an increase in size.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
