Description

Frame for plate type heat exchanger used in Plant}

The present invention relates to a plate heat exchanger included in various plant equipment, and more particularly, to a plate heat exchanger frame for a plant equipment that has good disassembly and assembly performance of a heat exchanger plate and enables easy maintenance.

The heat exchanger is a key equipment that is widely used in almost all industrial fields to promote heat transfer between fluids by contacting a high temperature fluid and a low temperature fluid. There are various types of heat exchangers, such as a multi-tube type, a double tube type, a liquid film type, a coil type, and a plate type. Among them, the plate type heat exchanger does not occupy a large space and has good characteristics.

1 is a side view schematically showing the structure of a conventional plate heat exchanger 10, and FIG. 2 is a view showing the heat exchanger plate of FIG. 1 separately.

As shown, the plate-type heat exchanger 10, the fixed plate 11 fixed vertically, coupled to the upper end of the fixed plate 11 horizontally extended horizontal beam 12, horizontal beam 12, the extended end The vertical counter column (13) connected to the fixed plate (11) and the guide beam (15) connecting the counter column (13), the horizontal beam (12) supported by a position controllable support plate (14), fixed plate A plurality of heat exchanger plates (17) interposed between the (11) and the crimp plate (14), and a tie rod (16) for pressing the crimp plate (14) toward the fixing plate (11) are provided.

The horizontal beam has a cross-sectional structure of an I-beam and provides a locking flange 12a of a certain width. The locking flange 12a is a portion that supports the inlet end portion 17c at the top of the heat transfer plate 17. The upper end portion of the heat transfer plate 17 is supported by being caught by the locking flange 12a.

However, the above-described conventional heat exchanger 10 has a problem in that it is inconvenient to mount or remove the heat transfer plate 17 with respect to the horizontal beam. The reason is that the interval w of the inlet end portion 17c of the heat transfer plate 17 is narrower than the width of the engaging flange 12a.

In order to support the heat transfer plate 17 to the engagement flange 12a, the heat transfer plate 17 is tilted to one side, and one entrance end 17c is first applied to the engagement flange 12a, so that the heating plate itself is moved, and the engagement flange ( It is necessary to move the widthwise end portion of 12a) until it reaches the inward groove portion 17e in the accommodation space 17b, and then rotate the heat transfer plate in the opposite direction so that the opposite inlet end is hung on the locking flange 12a. Through the above process, as the engagement flange 12a is accommodated in the accommodation space 17b, the heat transfer plate 17 is mounted. The separation of the heat transfer plate 17 with respect to the horizontal beam 12 is made in the reverse order.

In this way, the conventional plate-type heat exchanger is cumbersome and detachable as the heat exchanger plate 17 needs to be rotated left and right to mount or remove the heat exchanger plate 17. In order to maintain the heat exchanger 10, the heat exchanger plate 17 needs to be periodically disassembled to clean the inside, and the disassembly or assembly inconvenience of the heat exchanger plate 17 may lead to negligence in the management of the heat exchanger.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

The present invention relates to a frame of a plate heat exchanger included in various plant equipment. Plant facilities are installed in a wide variety of industrial facilities, such as cogeneration plants, industrial complexes or steel mills, and almost always include heat exchangers. The plate-type heat exchanger frame of the present invention has a structure capable of maintaining the best efficiency of the heat exchanger itself by improving the maintainability of the heat exchanger plate.

3 is a perspective view of a plate-type heat exchanger frame 20 for plant equipment according to an embodiment of the present invention, and FIG. 4 is a view for explaining a vertical position confirmation method of the compression plate shown in FIG. 3. 5 is a cross-sectional view for explaining the structure of the power supporter 40 of FIG. 3.

As shown, the heat exchanger frame 20 according to the present embodiment includes a fixed plate 30, a power supporter 40, a counter column 50, a guide beam 70, and a crimping plate 60. .

The fixed plate 30 is a steel member in the form of a substantially square plate having a predetermined thickness and is vertically erected on the bottom surface. In addition, a plurality of tie rod receiving grooves 31c are formed at the edge portion of the fixed plate 30.

The tie rod receiving groove 31c is a hole through which the tie rod 16 is fitted. The tie rod 16 is to press the crimping plate 60 to the fixed plate 30, as shown in Figure 7, the horizontally extending male threaded rod (16b), two coupled to the male threaded rod (16b) A plastic protective tube 16c for protecting the nut 16a and the male threaded rod 16b is provided.

In addition, the fixing plate 30 is provided with four through holes 31a. Each through-hole 31a is a passage through which fluid flows in and out, and the piping connection portion 31b is fixed as shown in FIG. 7.

The power supporter 40 supports a plurality of heat transfer plates 17 and supports the crimping plate 60 to be position-adjustable in the direction of the arrow e or the opposite direction, the horizontal beam 41 and the driving rail 43 ), and a heat transfer plate support portion 80.

Horizontal beam 41, one end is fixed to the upper end of the fixing plate 30, the other end is coupled to the upper end of the counter column (50). The horizontal beam 41 extends horizontally and bears the load of the crimping plate 60. The horizontal beam has a cross-sectional shape of a normal I-beam, and includes an upper flange portion 41a, a lower flange portion 41c, and a web portion 41b.

The upper flange portion 41a has a certain width and extends horizontally and has two rows of running rails 43 thereon. The driving rail 43 is a belt-shaped member extending in the longitudinal direction of the horizontal beam 41 and having a tooth portion 43a formed on its upper surface, and bolted to the upper flange portion 41a. The driving rails 43 are spaced apart from each other in parallel, and mesh with the toothed wheel 62 to be described later.

As shown in FIG. 6D, the heat exchanger plate support portion 80 is to hang and support the upper end portion of the heat exchanger plate 17 and has a lower fixed beam 81 and a plurality of doors 82.

The lower fixed beam 81, like the horizontal beam 41, takes a cross-sectional shape of an I beam, and is fixed to the bottom of the fixed flange portion 81a and the fixed flange portion 81a, which is fixed to the bottom surface of the lower flange portion 41c. It has a guide flange portion 81c, a fixed flange portion 81a and a web portion 81b that connects the guide flange portion 81c. The lower fixed beam 81 is fixed to the lower portion of the horizontal beam 41, and both ends are fixed to the fixed plate 30 and the counter column 50, respectively.

In particular, a plurality of door mounting holes 81d are provided in the guide flange portion 81c. As illustrated in FIG. 6C, the door mounting hole 81d is a passage through which the inlet end 17c at the top of the heat exchanger plate 17 passes upward simultaneously, and is formed in a plurality of directions in the longitudinal direction of the guide flange 81c. It is symmetrical based on the web portion 81b.

In addition, the door 82 is installed in each door mounting opening 81d so as to be opened and closed. The door 82 is connected to the guide flange portion 81c by a hinge 82a, and is pushed by an upper inlet end portion 17c that moves vertically upward and rotates to open in the direction of the arrow n. The door 82 is closed and has the same plane as the guide flange portion 81c.

On the other hand, the counter column 50 is a column fixed vertically to the bottom surface, and supports the power supporter 40 horizontally with the fixed plate 30.

The motor support 53 is fixed to the outer portion of the counter column 50. The motor support 53 is a support for supporting the traction motor 55a. The traction motor 55a receives rotational torque received from the outside and outputs rotation torque, and has a winding reel 55b on the drive shaft.

In addition, the support pulley 54b is located at the upper end of the counter column 50. The supporting pulley 54b is rotatably supported by the pulley holder 54a and supports the tension wire 55c.

The tension wire 55c is a steel wire whose one end is fixed to the eye bolt 62d of the wheel housing 61c, which will be described later, and the other end is a steel wire wound around the winding reel 55b, and is tensioned when driving the traction motor 55a. And the squeezing plate 60 is pulled in the direction of the arrow e. As the squeeze plate 60 moves, the toothed wheel 62 rolls over the driving rail 43.

The reason for pulling the crimp plate 60 in the direction of the arrow e is to secure a space between the fixed plate 30 and the crimp plate 60. In addition, the reason for securing the space is that a space for installing the heat exchanger plate 17 is required when the heat exchanger 100 is newly manufactured, and when the heat exchanger 100 is cleaned, the heat exchanger plate 17 is removed and reinserted. This is because space is required. The pressing plate 60 is moved in the opposite direction of the arrow e direction by the man's manpower and the tie rod 16 which is a fixing means.

The guide beam 70 is a rectangular rod having a predetermined cross-sectional shape in the longitudinal direction, one end of which is fixed to the fixing plate 30 and the other end of the guide column to the counter column 50. The guide beam 70 is positioned below the vertical direction of the lower fixed beam 81 and maintains horizontal.

The vertical gap K between the guide beam 70 and the guide flange portion 81c is smaller than the height H of the heat transfer plate 17, as shown in FIG. 6A. The reason for designing the gap K is smaller than the height H of the heat exchanger plate is that the heat exchanger plate 17 in the assembled state is simultaneously supported by the heat exchanger plate support portion 80 and the guide beam 70 as shown in FIG. 6D. It is considered to be possible.

A plurality of right angle grooves 75 are formed in the guide beam 70 at regular intervals. The right angle groove 75 corresponds one-to-one to the door mounting hole 81d, and forms a right angle to the longitudinal direction of the guide beam 70. Right angle groove 75, as shown in Figure 6a, accommodates the lower end of the heat transfer plate 17 horizontally moving in the direction of the arrow f, the heat transfer plate 17, the lower fixed beam 81 and the guide beam (70) It allows you to take a vertical posture between.

In addition, a vertical positioning unit 74 is installed below the guide beam 70. The vertical positioning unit 74 serves to determine whether the crimp plate 60 supported by the horizontal beam 41 is inclined in the direction of the arrow m or the opposite direction based on the vertical line V.

As shown in FIG. 4, the vertical positioning unit 74 has a sensor holder 73 protruding from a lower center portion of the guide beam 70 and first and second intervals arranged on both sides of the sensor holder 73. And sensors 74a, 74b. The sensor holder 73 extends along the longitudinal direction of the guide beam 70 and supports the first and second spacing sensors 74a and 74b. A plurality of first and second interval sensors 74a and 74b are continuously arranged along the longitudinal direction of the sensor holder 73.

The first interval sensor 74a and the second interval sensor 74b are located on opposite sides with the sensor holder 73 interposed therebetween, and measure the distances D1 and D2 from the sensing target surface 61e. This will be described later.

The crimping plate 60 is a plate-shaped member of a predetermined thickness supported so as to be able to adjust the position of the power supporter 40. The compression plate 60 is made of steel, like the fixed plate 30, and takes a substantially rectangular shape. In addition, a plurality of tie rod receiving grooves (61a) is formed on the rim portion of the compression plate (60). The tie rod receiving groove 61a accommodates the straight tie rod 16 as shown in FIG. 7.

In addition, a wheel housing 61c is fixed to the upper portion of the crimp plate 60 by welding. The wheel housing 61c is a U-shaped bracket that is opened downward, and accommodates the toothed wheel 62 rotatably with both ends fixed to the crimp plate 60. The toothed wheel 62 is supported on the wheel housing 61c through the wheel shaft 62c and is capable of rolling motion.

The toothed wheel 62 has a meshing portion 62a on both sides of the outer circumferential surface, and a groove portion 62b in the center. The engaging portion 62a meshes with the toothed portion 43a of the travel rail 43. Since the engaging portion 62a meshes with the toothed portion 43a, slipping of the toothed wheel 62 does not occur. For example, when the crimping plate 60 is moved, the left end portion in the width direction of the crimping plate 60 moves before the right end or the right end does not move before the left end. In other words, the imaginary plane including the compression plate 60 is always orthogonal to the longitudinal direction of the horizontal beam 41.

The groove portion 62b is a groove for the purpose of putting the lever (not shown) and lifting it up again. For example, when the lever is retracted while the end of the lever is inserted between the groove portion 62b and the upper flange portion 41a, the lever can press the groove portion 62b upward and forcefully rotate the toothed wheel 62. . It is also possible to move the crimping plate 60 using a lever.

The lower center groove 61b is provided at the center of the lower end of the compression plate 60. The lower center groove 61b is a groove that opens to the lower portion and accommodates the guide beam 70, and as shown in FIG. 4, has a width T2 greater than the width T1 of the guide beam 70.

In the lower center groove 61b, the surface facing the guide beam 70 is the sensing target surface 61e. The sensing target surface 61e is spaced apart from the guide beam 70. In the state in which the compression plate 60 is maintained vertically, the distance between the both-side sensing target surface 61e and the guide beam 70 is the same.

The above-described first interval sensor 74a and second interval sensor 74b measure the distances D1 and D2 between the sensing target surfaces 61e facing each other. The information measured by the first and second interval sensors 74a and 74b is sent to the controller 56 through the signal cable 74c.

The intervals D1 and D2 between the first and second interval sensors 74a and 74b and the sensing target surface 61e are the same when the crimp plate 60 is positioned vertically. However, when the compression plate 60 is inclined in one direction, D1 is greater than D2, or D2 is greater than D1. The controller 56 may determine the inclination and the inclination angle of the crimp plate 60 based on the difference between the gap values D1 and D2.

In the counter column 50, a display unit 51, a normal lamp 52a, a tilting lamp 52b, and a controller 56 are provided.

The controller 56 is connected to the first and second interval sensors 74a and 74b through the signal cable 74c, and receives the contents measured by the first and second interval sensors, and the above-described interval values D1 and D2 are the same. If there is a difference, if there is a difference, the difference value is determined, and the obtained result is transmitted to the display unit 51. The display unit 51 displays whether the current compression plate 60 is vertical and the angle when it is inclined.

In addition, the normal lamp 52a is lit when the intervals measured by the first and second interval sensors 74a and 74b are the same, and the inclined lamp 52b is a lamp that is lit when the intervals are not the same. The crimping plate 60 can be more precisely assembled using the display unit 51, the normal lamp 52a, and the tilting lamp 52b.

6A to 6D are views for explaining a mounting method of the heat exchanger plate 17 to the heat exchanger frame 20 of FIG. 3.

As shown in the figure, the heat transfer plate 17 is horizontally moved in the direction of the arrow f in a vertically standing state, and the heat transfer plate 17 is positioned between the lower portion of the door 82 and the right angle groove 75. While the heat transfer plate 17 is horizontally moved in the direction of the arrow f, the lower end portion of the heat transfer plate 17 passes through the right angle groove 75. In other words, the lower end of the heat transfer plate 17 should be fitted to the right-angle groove 75, so that the heat transfer plate is entered between the door 82 and the guide beam 70. The reason is that, as mentioned above, the distance K between the horizontal beam 41 and the guide beam 70 is smaller than the height H of the heat transfer plate 17.

Through the above process, if the inlet ends 17c on both sides of the upper end of the heat exchanger plate 17 are positioned at the vertical lower portion of the door 82, the heat exchanger plate 17 is completely raised in the direction of the arrow g. When the heat transfer plate 17 is raised, as shown in FIG. 6C, the entrance end portion 17c pushes the door 82 upward and rewinds, passing upward through the door mount 81d to the upper portion of the lower flange portion 81c. Goes up At this time, the guide flange portion 81c enters the accommodation space 17b of the heat transfer plate 17. In addition, the lower end portion of the heat transfer plate 17 is separated from the right-angle groove 75.

In this state, the heat transfer plate 17 is moved to the fixed plate 30. By repeating the above operation, the desired number of heat transfer plates 17 are mounted. If the heat transfer plate 17 is most closely attached, after the door 82 is closed, the crimping plate 60 is crimped to the fixed plate 30 side using a tie rod 16. Separation of the heat transfer plate 17 proceeds in the reverse order of the above-described order.

7 is a side view showing the overall structure of a heat exchanger to which the heat exchanger frame 20 according to an embodiment of the present invention is applied.

As shown, a plurality of heat transfer plates 17 are crimped between the fixed plate 30 and the crimping plate 60. The high-temperature fluid and the low-temperature fluid injected from the outside pass through the heat exchanger plate 17 and are heat exchanged and then fall out.

A plurality of tie rods 16 are used as fixing means for fixing the crimping plate 60 to the fixing plate 30. The tie rod 16 itself is a general one, and has a male threaded rod 16b that extends straight, two nuts 16a coupled to each male threaded rod 16b, and a protective tube 16c that protects the male threaded rod 16b. .

The male threaded rod 16b is kept horizontal in a state fitted between the tie rod receiving groove 31c of the fixed plate 30 and the tie rod receiving groove 61a of the crimp plate 60. In addition, one of the nuts 16a is engaged with the male threaded rod 16b from the outside of the fixing plate 30, and the other nut is screwed with the male threaded rod 16b from the outside of the crimp plate 60. According to the fastening of the nut, the male threaded rod 16b is tensioned, and the crimping plate 60 is crimped to the fixed plate 30 side with its reaction force, and the heat transfer plate 17 is brought into close contact.

As described above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical spirit of the present invention.
