Description

  The present invention relates to a steam / water separator, and more particularly to a centrifugal steam / water separator.

  Centrifugal air / water separators turn steam by introducing steam into a vertical cylindrical cylinder, and the centrifugal force generated by the rotation causes moisture to fly to the peripheral side wall of the cylinder and drop it off. To improve. The steam with improved dryness is led out from the steam outlet pipe at the upper part of the trunk, while the separated water is led out from the separated water outlet pipe at the lower part of the trunk.

  In this type of steam separator, as detailed in the prior art section of Patent Document 1 below, in order to smoothly lead out the water separated by swirling from the separated water outlet pipe (precipitation pipe), A partition plate is provided inside. In the invention described in Patent Document 1, a conical entanglement preventing body (20) is further provided on the partition plate (17) to improve the dryness of the steam.

  However, as the partition plate (17), a disc adapted to the inner diameter of the cylinder (separation cylinder 11) is used, and the outer peripheral portion of this disc is cut out in an arc shape at equal intervals in the circumferential direction to form the gap (18). doing. In other words, the partition plate is provided with tongue pieces extending radially outward at a plurality of locations in the circumferential direction of the disk, and an arcuate gap (18) is formed between the tongue pieces. Then, the partition plate is positioned with respect to the barrel with the extending tip of the tongue piece applied to the inner peripheral surface of the barrel. However, in such a configuration, there is a possibility that water drops that hang down the inner peripheral surface of the trunk will bounce off the tongue pieces. In the invention described in Patent Literature 1, such a splash of water droplets is prevented by the entanglement preventing body (20).

  By the way, although there exists a possibility that solids, such as rust in piping, may be contained in the vapor | steam into a trunk | drum, this solid substance also falls below with a water droplet by turning. Therefore, it is preferable that the lower part in the trunk can be further divided into “liquid (water)” and “solid (rust)”. Has already filed a patent application (Japanese Patent Application No. 2009-18570). However, when the strainer is to be provided in the lower part of the steam separator, the structure in which the partition plate is supported on the bottom wall of the trunk by the anti-rotation body (19) as in the invention described in Patent Document 1, the strainer Inconvenient for installation.

  On the other hand, Patent Document 2 proposes that the partition plate (10) is held by a vertical plate-shaped water recirculation prevention plate (11). However, since the lower surface of the partition plate and the upper surface of the anti-rotation plate coincide with each other, the water droplets that drip down the inner peripheral surface of the trunk bounce off the upper surface of the anti-rotation plate and get involved in the swirl flow again. There is a fear. In the first place, in the invention described in Patent Document 2, the body of the steam separator is provided with a water supply port (8) below the partition plate, while a concentrated water blow port (9) is provided above the partition plate. "Prevents mixing of the concentrated water and the feed water in the upper part of the steam / water separator" (the second page, upper left column, lines 6-7). Therefore, it is premised on that water also accumulates above the partition plate in the body, and with such a configuration, the dryness of the steam cannot be improved.

Alternatively, the body 2 may be formed in a simple cylindrical shape as a whole.

  The body 2 is provided with a top plate 8 at the upper end to close the upper opening, and a bottom plate 9 at the lower end to close the lower opening. The top plate 8 and the bottom plate 9 may be formed in a flat plate shape, or may be formed so as to bulge outward in the vertical direction of the body 2.

  The top plate 8 and the bottom plate 9 are integrated with the body 2 by welding or the like, or are detachably attached to the body 2. In this embodiment, the top plate 8 is welded to the upper end portion of the barrel 2, but the bottom plate 9 is detachably provided at the lower end portion of the barrel 2. Specifically, a flange 10 is provided at the lower end of the truncated cone portion 7 of the barrel 2, and a bottom plate 9 is superimposed on the lower surface of the flange 10 and is detachably held by a bolt nut 11.

  When the bottom plate 9 is detachably provided on the body 2, it is preferable that the bottom plate 9 is provided with a drain hole 12 so that it can be opened and closed. The reason is that the water accumulated in the barrel 2 can be discharged by opening the drain hole 12 in advance before removing the bottom plate 9 from the barrel 2. In the present embodiment, the drain hole 12 formed in the bottom plate 9 can be opened and closed by screwing the plug 13 in a detachable manner.

  The steam inlet pipe 3 is formed in a cylindrical shape having a smaller diameter than that of the body 2 and is usually formed in a cylindrical shape having a diameter equal to or smaller than that of the body 2. The steam inlet pipe 3 is connected to the peripheral side wall of the barrel 2 so that the hollow hole communicates with the inside of the barrel 2. At this time, the steam inlet pipe 3 is connected to the peripheral side wall of the barrel 2 at a position higher than the vertical center of the barrel 2. As will be described later, steam is introduced into the barrel 2 through the steam inlet tube 3, but the steam inlet tube with respect to the barrel 2 is rotated so that the steam introduced into the barrel 2 swirls within the barrel 2. 3 placement is determined.

  Typically, the steam inlet pipe 3 is connected tangentially to the peripheral side wall of the barrel 2 at the upper end of the barrel 2. Specifically, in the state shown in the drawing, the steam inlet pipe 3 is arranged with its axis line along the left-right direction, and one end in the axial direction is connected to the peripheral side wall of the barrel 2. At this time, as shown in FIG. 2, the steam inlet pipe 3 is arranged such that the rear end portion of the peripheral side wall is disposed at the rear end portion of the peripheral side wall of the barrel 2 at one end portion in the axial direction.

  The steam inlet pipe 3 includes a flange 14 at the other axial end. Using this flange 14, a steam pipe can be connected to the steam inlet pipe 3. Thereby, the steam can be introduced into the barrel 2 in the tangential direction via the steam inlet pipe 3.

  The steam outlet pipe 4 has a cylindrical shape with a diameter smaller than that of the body 2 and is disposed along the axis thereof in the vertical direction. The steam outlet pipe 4 is provided at the center of the top plate 8 of the barrel 2 so that the hollow hole communicates with the inside of the barrel 2. At this time, the steam outlet pipe 4 is provided so as to extend upward from the top plate 8 of the trunk 2. A flange 15 is provided at the upper end of the steam outlet pipe 4. By using this flange 15, a pipe to a steam use facility (not shown) can be connected to the steam outlet pipe 4.

  On the other hand, the lower end portion of the steam outlet pipe 4 is preferably provided so as to penetrate into the body 2. In the present embodiment, the steam outlet pipe 4 is disposed on the same axis as the body 2 and is provided so as to penetrate the top plate 8 of the body 2 vertically. When the lower end portion of the steam outlet pipe 4 is provided so as to enter the body 2, the steam outlet pipe 4 is preferably provided so as to enter below the connecting portion between the body 2 and the steam inlet pipe 3. A draining portion 16 that expands downward may be provided on the outer peripheral surface of the entry portion as desired.

  In the present embodiment, the steam outlet pipe 4 is provided with only one draining portion 16, but a plurality of upper and lower parts may be provided if desired. The draining portion 16 is formed in a truncated cone shape that is coaxial with the steam outlet pipe 4 and has an acute angle (that is, less than 90 °). The draining portion 16 is preferably provided below the connecting portion between the body 2 and the steam inlet pipe 3. Moreover, it is preferable to provide the draining portion 16 at a position spaced upward from the lower end portion of the steam outlet pipe 4.

  The separation water outlet pipe 5 is a circular tube having a smaller diameter than that of the body 2, and is provided at the center of the bottom plate 9 of the body 2 so that the hollow hole communicates with the inside of the body 2. In the illustrated example, the separated water outlet pipe 5 is formed in a substantially L shape with a vertical pipe portion 17 arranged along the vertical direction and a horizontal pipe portion 18 arranged along the horizontal direction from the lower end portion thereof. Has been. And while the upper end part of the vertical pipe part 17 is connected to the bottom plate 9, the front-end | tip part of the horizontal pipe part 18 is connected to the lower trap (not shown) of a steam trap (not shown), for example. .

  A strainer 19 may be provided at the opening of the separated water outlet pipe 5 into the body 2. In the illustrated example, a cylindrical strainer 19 is provided so as to protrude from the bottom plate 9 into the body 2 so as to be continuous with the vertical pipe portion 17 of the separated water outlet pipe 5. The strainer 19 is formed in a cylindrical shape opened up and down, and the peripheral side wall is formed in a net shape or a porous plate shape. More specifically, the strainer 19 is composed of a mesh or punching metal pipe, and the pipe is disposed along the vertical direction of the pipe and is provided continuously with the vertical pipe portion 17 of the separation water outlet pipe 5. It is done.

  The partition plate 6 has a disk shape smaller in diameter than the inner diameter of the barrel 2 and is provided horizontally in the middle in the vertical direction in the barrel 2. Specifically, the partition plate 6 is provided at a position slightly above the lower end portion of the body 2 and is provided at a height corresponding to the upper end portion of the truncated cone portion 7 in the illustrated example. At this time, the partition plate 6 is arranged so that the center thereof coincides with the axis of the trunk 2. Thus, a continuous annular gap is opened between the outer peripheral surface of the partition plate 6 and the inner peripheral surface of the body 2. Further, the partition plate 6 is provided below the lower end portion of the steam outlet pipe 4 and is provided above the upper end portion of the separated water outlet pipe 5 and the cylindrical strainer 19 provided on the upper side thereof. . The structure for attaching the partition plate 6 to the body 2 will be described in detail later.

  Since the steam-water separator 1 of the present embodiment is configured as described above, the steam from the steam inlet pipe 3 is introduced into the barrel 2 in a tangential direction. As a result, a swirling flow of steam is generated in the body 2 and air-water separation is achieved. Specifically, the steam from the steam inlet pipe 3 is wet saturated steam as a steam-water mixture, but is swirled in the body 2 to achieve steam-water separation by centrifugal force. That is, moisture is blown outward by centrifugal force and dropped downward, while the steam whose dryness is improved by such centrifugation is led out from the upper steam outlet pipe 4. When the draining part 16 is provided in the steam outlet pipe 4, the water droplets that hang down the outer peripheral surface of the steam outlet pipe 4 are blown to the peripheral side wall of the trunk 2 by the draining part 16 that spreads downward. Inhalation is prevented.

  Further, the steam introduced into the trunk 2 through the steam inlet pipe 3 may contain solid matter such as rust in the pipe. Drops downward by turning. In this way, separated water and rust are guided to the lower region of the partition plate 6. Furthermore, if the strainer 19 is provided in the lower part of the body 2 as in the present embodiment, only moisture can be discharged to the separated water outlet pipe 5 through the strainer 19. That is, according to the steam separator 1 of the present embodiment, it can be separated into three types of “gas (vapor)”, “liquid (water)” and “solid (rust)”. And although rust accumulates in the lower part in the trunk | drum 2, by installing the partition plate 6, it is prevented that rust is scattered again by the airflow in the trunk | drum 2. FIG. The captured rust can be discharged from the barrel 2 by removing the bottom plate 9 of the barrel 2 as appropriate. At this time, first, by removing the plug 13 from the bottom plate 9, water accumulated in the body 2 can be drained in advance, and then the bottom plate 9 can be removed from the body 2 for work.

  Next, the attachment structure of the partition plate 6 to the trunk | drum 2 is demonstrated. FIG. 3 is a schematic perspective view of the partition plate 6 of the steam / water separator 1 according to the present embodiment as viewed from below, and shows a structure for attaching the partition plate 6 to the body 2.

  As shown in FIGS. 1 to 3, in this embodiment, the partition plate 6 is held on the peripheral side wall of the barrel 2 by a plate-like attachment material 20 at a plurality of locations (three locations in the illustrated example) that are equally spaced in the circumferential direction. Is done. Each attachment member 20 is formed of an elongated rectangular plate material, and is used with its plate surface vertical. Each attachment member 20 is arranged radially at the lower portion of the partition plate 6, leaving the central portion of the partition plate 6, and extends outward from the outer peripheral edge of the partition plate 6. The extending tip 21 is held on the peripheral side wall of the barrel 2.

  Each attachment member 20 is formed with a rectangular cutout 22 in the upper part in the region from the front of the outer peripheral edge of the partition plate 6 to the extending tip 21. As a result, an upwardly protruding portion 23 remains in each attachment material 20 at a location where the notch 22 is not formed. The protruding portion 23 is spaced apart from the outer peripheral edge of the partition plate 6 and is disposed on the inner side of the outer peripheral edge of the partition plate 6. Then, the lower surface of the partition plate 6 is placed on and held by the upper end surface of the protruding portion 23.

  In this manner, the attachment member 20 that holds the partition plate 6 on the barrel 2 is provided at the lower portion of the partition plate 6 and is held on the peripheral side wall of the barrel 2. Further, a continuous annular gap is opened between the outer peripheral surface of the partition plate 6 and the inner peripheral surface of the body 2. Further, the connecting portion (the projecting portion 23 in the present embodiment) between the partition plate 6 and the mounting member 20 is spaced inward from the outer peripheral edge of the partition plate 6, that is, more than the set inner side than the outer peripheral edge of the partition plate 6. Placed in. Further, the attachment member 20 is spaced below the lower surface of the partition plate 6 in the region from the holding portion (in the present embodiment, the extended tip portion 21) to the peripheral side wall of the barrel 2 to the connection portion with the partition plate 6. That is, it is arranged below the setting or lower than the lower surface of the partition plate 6.

  Since the partition plate 6 is held on the body 2 with such a configuration, water droplets and rust that fall downward along the inner peripheral surface of the body 2 bounce off the partition plate 6 and its mounting material 20 and are again involved in the swirl flow. Is prevented from falling off from the partition plate 6 with certainty. In addition, since the mounting member 20 is held not on the bottom plate 9 of the barrel 2 but on the peripheral side wall, it does not get in the way when the strainer 19 is provided in the lower portion of the barrel 2.

  By the way, according to an experiment, in order to prevent water droplets that hang downward along the inner peripheral surface of the barrel 2 from hitting the partition plate 6, there is no difference between the outer peripheral surface of the partition plate 6 and the inner peripheral surface of the barrel 2. The gap A needs to exceed 5 mm, and 10 mm or more was preferable. In this embodiment, the inner diameter of the barrel 2 is 200 mm, the outer diameter of the partition plate 6 is 170 mm, and the gap A between the outer peripheral surface of the partition plate 6 and the inner peripheral surface of the barrel 2 is 15 mm. The inner diameter of the steam inlet pipe 3 is 100 mm, and the inner diameter of the steam outlet pipe 4 is 100 mm.

  Further, in order to prevent water drops that hang downward along the inner peripheral surface of the body 2 from bouncing back at the upper end surface of the attachment member 20 and being caught in the swirling flow again, the notch 22 of the attachment member 20 has a height in the vertical direction. It is preferable to set the length B to 5 mm or more. That is, the vertical distance B between the lower surface of the partition plate 6 and the bottom surface of the notch 22 is set to 5 mm or more. In this embodiment, it is set to 8 mm, for example.

  Furthermore, for the same reason, the notch 22 needs to enter from the outer peripheral edge of the partition plate 6 to a set length or more and to the inside in the radial direction of the partition plate 6, but the entry length C is preferably several mm or more. . In this embodiment, it is set to 10 mm, for example.

  Hereinafter, modifications of the structure for attaching the partition plate 6 to the trunk 2 will be described. The attachment structure of the partition plate 6 to the body 2 is as follows: (a) the attachment material 20 is provided at the lower part of the partition plate 6; (b) the attachment material 20 is held on the peripheral side wall instead of the bottom plate 9 of the body 2; c) A point where a continuous annular gap is opened between the outer peripheral surface of the partition plate 6 and the inner peripheral surface of the body 2, and (d) the connecting portion between the partition plate 6 and the mounting member 20 is As long as the point spaced apart from the outer peripheral edge is satisfied, it can be changed as appropriate, and the following modification is one example.

  FIG. 4 is a schematic view showing a first modification of the structure for attaching the partition plate 6 to the body 2. In the first modification, the attachment member 20 includes a first member 24 that is stretched in the diameter direction of the body 2, and a second member 25 that is provided at the longitudinal center of the first member 24. Both are formed from a rectangular plate and used with the plate surface vertical. And the 2nd material 25 is piled up and fixed to the longitudinal direction center part (center part of the trunk | drum 2) of the 1st material 24. FIG. At this time, the second material 25 is arranged so that a part of the second material 25 protrudes upward from the first material 24, and the partition plate 6 is held by the protruding portion 23.

  In the first modification, the attachment member 20 is composed of a plurality of members (24, 25). However, as in the above-described embodiment, the attachment member 20 is formed by forming notches in the upper portions of both ends in the longitudinal direction of a single plate member. It's okay. Or conversely, in the above-described embodiment, each attachment member 20 may be composed of a plurality of members. That is, in order to realize the configuration of FIG. 3, the second material 25 may be provided so as to protrude upward in a part of the first material 24 in the longitudinal direction, and the partition plate 6 may be held by the protruding portion 23.

  Further, the attachment material 20 is not necessarily arranged in the diameter direction of the partition plate 6 and the trunk 2. Therefore, for example, in FIG. 4, a plurality of mounting members 20 are arranged in front and back in parallel, and the partition plate 6 is held at a plurality of locations by the upward projecting portions 23 provided at the center in the longitudinal direction of each mounting member 20. May be.

  FIG. 5 is a schematic diagram showing a second modification of the structure for attaching the partition plate 6 to the body 2. In the second modification, the attachment member 20 is formed of a plate member or a rod member, and is provided so as to incline downward from the lower surface on the inner side of the setting plate or more than the outer peripheral edge of the partition plate 6 toward the radially outer side.

  FIG. 6 is a schematic view showing a third modification of the structure for attaching the partition plate 6 to the body 2. In the second modification, the partition plate 6 is held by the mounting members 20 arranged at equal intervals in the circumferential direction of the partition plate 6. However, in the third modification, both longitudinal ends 26 and 26 of one plate material are It is bent and formed so as to incline radially outward of the partition plate 6 as it goes downward. The partition plate 6 is placed and held on the upper surface of the horizontal portion 27 at the center of the mounting material 20. Also in this case, a plurality of attachment members 20 may be provided in parallel, and the partition plate 6 may be held by the horizontal portion 27 at each center. In any case, both end portions in the longitudinal direction of the horizontal portion 27 and the outer peripheral edge of the partition plate 6 are arranged apart from each other by a set amount or more.

  The steam-water separator 1 of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. For example, in the above embodiment, the case of improving the dryness of water vapor has been described, but the steam / water separator 1 of the present invention can be similarly applied to other gas / liquid separation. In other words, a gas-liquid mixture other than water vapor is introduced into the body 2 from the steam inlet pipe 3 as steam, and after the droplets and solids are separated and removed by swirling in the body 2, the gas having improved dryness is steamed. While being led out from the outlet pipe 4, the separated liquid may be led out from the separated water outlet pipe 5.

  Moreover, in the said Example, although the drain hole 12 was provided in the baseplate 9, the drain hole 12 may not be provided depending on the case. Moreover, in the said Example, although the drain hole 12 of the baseplate 9 was made openable / closable by the plug 13, you may make it openable / closable by a valve | bulb. Further, the drain hole 12 may be used for draining when removing the bottom plate 9, or by forming a relatively large diameter, the plug 13 or the valve can be opened to remove solid matter such as rust. It is good also as a structure which makes it fall naturally outside the trunk | drum 2. FIG.

  In the above embodiment, the strainer 19 is provided in the lower part of the body 2, but the strainer 19 is not always necessary. Even when the strainer 19 is provided, the shape and size thereof can be changed as appropriate.

  Further, in the above embodiment, the separation water outlet pipe 5 is connected to the bottom plate 9 of the cylinder 2, but the separation water outlet pipe 5 may be connected to the peripheral side wall at the bottom of the cylinder 2. For example, the separated water outlet pipe 5 may be connected to the upper part of the truncated cone part 7 and at a position below the partition plate 6. In this case, water and rust accumulate in the lower part of the body 2, and overflow water that is less likely to contain rust is led out to the separated water outlet pipe 5. In order to obtain the same effect as this, the separation water outlet pipe 5 may be plunged into the body 2 from the bottom plate 9 of the body 2. That is, in FIG. 1, the strainer 19 may be the same pipe as the vertical pipe portion 17.
