Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dye-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dye-liquid heat exchanger for dyeing dye for dyeing fibers and for heating or cooling the dye-containing liquid to a required temperature, and more particularly, .

The salt-water heat exchanger used in the dyeing plant is configured to operate a steam boiler to generate a large amount of steam, and to introduce the steam into the heat exchanger to heat the salt solution. The structure of the salt- The following is a reference.

The conventional saltwater heat exchanger for a dyeing machine has a structure in which a salt solution inlet 51 is formed at one side of the tubular body 54 and a salt solution outlet 52 is formed at the other side and a plurality of heat exchange pipes 53 So that the space between the supports becomes the steam heating space 59.

A steam inlet 55 for injecting steam (or cooling water) into the steam heating space 59 is formed at one side of the upper portion of the tubular body 54, and a steam outlet 56 is formed at the other side of the tubular body 54, During the passage through the heat exchange pipe, the salt liquid is heated by the heat exchange action by the steam injected through the steam inlet 55. Reference numeral 60 denotes a condensate discharge pipe.

In the conventional dye-base heat exchanger for dyeing machine, the salt solution injected through the salt solution inlet 51 passes through the heat exchange pipe 53 and is heat-exchanged by the steam injected through the steam inlet during the heat exchange pipe. Since the actual heat exchange action occurs only during the passage of the salt solution through the plurality of heat exchange pipes 53 having a small diameter, an efficient heat transfer area can not be used and the heat exchange efficiency is inevitably low. In addition, since heat is wasted to the outside by the cylinder 54 heated by steam, a thick heat-insulating pad 57 must be formed outside the cylinder, so that the manufacturing is inconvenient and the manufacturing cost is increased. There is an increased disadvantage.

Also, since the ordinary dye exchanger heat exchanger is long and horizontally long like a dyeing machine, the injected steam or cooling water can not be uniformly contacted with the heat exchange pipe 53, and the steam introduced through the steam inlet 55 Since the heat exchanger can be discharged to the steam outlet 56 without being restricted by the flow inside the cylinder 54, the structure of the heat exchanger can not uniformly heat the plurality of heat exchange pipes 53 disposed inside the cylinder 54 As a result, this problem also leads to a problem that the heat exchange efficiency is lowered.

In order to increase the temperature of the saline solution to 110 to 135 ° C, the time required for the saline solution to pass through the heat exchange pipe 53 must be kept as low as possible, The heat exchange efficiency is lowered in a short period of time and the maintenance and repair costs are wasted and time is short, and the life is short.

The heat exchange pipe (27) is a pipe-shaped inner space, and a salt solution, which is a heat exchange fluid, flows through the pipe. The heat exchange pipe (27) is in contact with high temperature steam located outside and takes charge of heat exchange. The heat exchange pipe 27 may be made of a metal material having excellent thermal conductivity.

The inlet side support 22 and the outlet side support 23 have a heat exchange pipe support hole 24 that engages with the heat exchange pipe 27. The inlet side support 22 is coupled to the lower end of the heat exchange pipe 27, The side support 23 is joined to the upper end of the heat exchange pipe 27. At this time, the number of the heat exchange pipe support holes 24 provided in the inlet side support 22 and the outlet side support 23 corresponds to the number of the heat exchange pipes 27 in the heat exchange apparatus.

In this case, the number, the size, the material, the length, the shape, and the like of the heat exchange pipes 27 can be adjusted in consideration of the oil resistance and the cooling efficiency, and the number of the heat exchange pipes 27 And the number of the heat exchange pipe support holes 24 formed in the outlet side support body 23 are determined.

On the other hand, the inlet side support member 22 has a steam injection pipe support hole 25 that engages with the steam injection pipe 31, and has a steam discharge pipe support hole 26 that engages with the steam discharge pipe 32.

The inner cylinder 20 engages with the inlet side support 22 and the outlet side support 23 to form a space for heat exchange.

The inner cylinder 20 is formed so as to surround the heat exchange pipe 27 and the BEFF plates 21 and 21` in the longitudinal direction of the heat exchange pipe 27 and between the inlet side support 22 and the outlet side support 23 . At this time, the lower end of the inner cylinder 20 engages with the outer circumferential surface of the inlet side support body 22, and the upper end of the inner cylinder body 20 engages with the outer circumferential surface of the outlet side support body 23.

The steam in the inner space formed by the inlet side support body 22, the outlet side support body 23 and the inner cylinder 20 undergoes heat exchange with the heat exchange pipe 27, .

The baffle plates 21 and 21` have heat exchange pipe support holes 24 that engage with the heat exchange pipe 27 and are positioned between the inlet support 22 and the outlet support 23 to form heat exchange pipes 27, Lt; / RTI > At this time, the number of the heat exchange pipe support holes 24 provided in the Baffle plates 21 and 21 'corresponds to the number of heat exchange pipes 27 in the heat exchange device.

The bent portions of the BEFF plate 21 and the BEFF plate 21 are alternately arranged in the longitudinal direction of the heat exchange pipe 27 As shown in FIG.

A steam injection pipe support hole 25 is formed in the bevel plate 21 so as to be coupled to the steam injection pipe 31. At this time, the steam injection pipe 31 coupled with the steam injection pipe support hole 25 of the inlet side support body 22 is connected to the outlet side support body 23 of the baffle plate 21 inside the inner cylinder 20, To the steam injection pipe support hole (25) of the steam injection pipe (21).

This technical feature of this embodiment is that the high temperature steam passing through the steam injection pipe 31 is injected into the inner cylinder 20 through the end of the steam injection pipe 31 adjacent to the outlet side support body 23, Is moved in a zigzag manner along the cut portions of the plates 21 and 21` and then discharged to the outside through the steam discharge pipe 32 coupled with the inlet side support 22. [

In this case, when the cut portion of the baffle plate 21 'is positioned along the longitudinal direction of the steam injection pipe 31, the steam injection pipe support hole 25 is not present in the baffle plate 21' The steam injection pipe support hole 25 may be formed only on the Baffle plate 21. In this case, the steam injection pipe 31 is connected to the steam supply pipe support hole 25 of the specific Baffle plate 21 and then passes through the cut portion of the other Baffle plate 21 ' To the baffle plate 21, 21 'adjacent to the outlet side support 23.

The main body pipe 13 constitutes the main body case 10 together with the inlet side induction plate body 11 and the outlet side induction plate body 12 and the main body case 10 constitutes the external shape of the heat exchange apparatus.

The main body pipe 13 is positioned to surround the inner cylinder 20 in the longitudinal direction of the inner cylinder 20 and is spaced from the inner cylinder 20 at a predetermined interval Respectively.

At this time, between the inner circumferential surface of the main pipe 13 and the outer circumferential surface of the inner cylinder 20, a spacing support 29 for forming the outer heat exchange space 28 is disposed at a predetermined interval.

The inlet side guide plate 11 is connected to the lower portion of the main body pipe 13 and connected to a salt solution inlet 14 for injecting the salt solution into the body case 10. The inlet side induction plate body 11 has a steam injection pipe support 16 for coupling with the steam injection pipe 31 and has a steam discharge pipe support 17 for coupling with the steam discharge pipe 32.

The outlet side guide plate 12 is connected to the upper portion of the main body pipe 13 and connected to a salt solution discharge port 15 for discharging the salt solution from the inside of the main body case 10.

At this time, the salt liquid injected into the body case 10 through the inlet side inlet plate 14 through the inlet inlet side 14 passes through the heat exchange pipe 27 coupled to the inlet side support body 22, . The salt solution injected into the main body case 10 through the inlet side inlet manifold body 11 through the inlet 14 of the salt solution flows through the external heat exchange space 28 between the inner cylinder 20 and the main body pipe 13, Side plate member 12 side. The thus-flowed salt liquid is discharged through the salt solution outlet 15 connected to the outlet side induction plate body 12.

First, the steam generated in the steam boiler or the like is introduced into one side of the steam injection pipe 31 exposed to the outside of the inlet side induction plate 11 of the main body case 10 The steam passes through the other end of the steam injection pipe 31 and is injected into the interior of the inner cylinder 20.

At this time, the steam passing through the steam injection pipe 31 is injected into the inner cylinder 20 through the end of the steam injection pipe 31 adjacent to the outlet side support member 23 in the inner cylinder 20. The steam is clogged by the inner wall of the Baffle plate 21, the outlet side support body 23 and the inner cylinder 20 and is fed downward along the cut portion of the Baffle plate 21 located at one side inside the inner cylinder 20 It proceeds. Thereafter, the steam is blocked by the inner wall of the Baffle plate 21, the inner wall of the Baffle plate 21 'and the Baffle plate 21', which is located at the other side inside the inner cylinder 20, Lt; RTI ID = 0.0 > a < / RTI > Through the repetition of this process, the steam injected into the inner cylinder 20 gradually condenses and moves in the direction of the steam discharge pipe 32 coupled to the inlet side support body 22, and as the proceeding direction is switched in a zigzag manner, The heat exchange pipe 27 and the inner cylinder 20 are more likely to contact each other. As a result, the residence time of the steam located in the inner cylinder 20 is extended and the heat exchange efficiency is improved.

On the other hand, the inlet side induction plate 11 is formed so that its diameter gradually increases in accordance with the direction of the flow of the saline solution, and the flow rate of the saline solution injected through the saline solution inlet 14 is reduced due to the diffusion of the passages, Passes through the external heat exchange space (28). At this time, the salt liquid comes into contact with the heat exchange pipe 27 heated by the high temperature steam and the external heat exchange space 28, and the temperature rises through heat exchange.

Thus, in this embodiment, the salt liquid to be heat-exchanged moves through the external heat exchange space 28 of the internal cylinder 20 surrounding the steam as well as the heat exchange pipe 27. In the conventional heat exchanger, when the steam is configured to enclose only the heat exchange pipe, the heat of the steam is wasted into the air through the outer wall. In order to prevent this, in this embodiment, the low-temperature solution is allowed to pass through the external heat exchange space 28 together with the heat exchange pipe 27 so that the saline solution receives the heat of the steam through the inner cylinder 20.

As a result, it is possible to minimize the waste heat radiated to the outside, so that a separate heat insulating material is not required, and the heat exchanging device can be miniaturized and lightened, and heat transfer efficiency can be improved by maximizing the heat transfer area. As the heat exchange efficiency is improved, energy consumption for generating steam is reduced, and the time required for the salt solution to stay in the heat exchange pipe (27) can be shortened to reduce the generation of scales.

Through this process, the high-temperature salt liquid having passed through the heat exchange pipe 27 and the external heat exchange space 28 is contracted by the outlet side induction plate body 12 whose diameter is gradually narrowed along the traveling direction, 15) to the dyeing machine.

The method for improving the heat exchange efficiency of the saline solution passing through the external heat exchange space 28 according to an embodiment of the present invention will be described in more detail with reference to FIG.

7 is a view showing a flow path forming portion 33 according to an embodiment of the present invention. The present embodiment is similar to the embodiment described with reference to Figs. 2 to 6, except for the flow path forming portion 33, and therefore, differences will be mainly described below.

Referring to Figs. 2 to 7, the flow path forming portion 33 shown in Fig. 7 is spirally located in the external heat exchange space 28. As shown in Fig. That is, the flow path forming portion 33 is spirally located between the outer circumferential surface of the inner cylinder 20 and the inner circumferential surface of the main body pipe 13, and forms a spiral flow path in the saline solution passing through the outer heat exchanging space 28.

At this time, at least one spacing zone 29 is located at a position adjacent to the inlet side support body 22 on the outer circumferential surface of the inner cylinder 20, and one or more spacing support members 29 are provided on the outer circumferential face of the inner cylinder 20, Or more spacing support 29 may be positioned to form the external heat exchange space 28. The flow path forming portion 33 is connected to the spacing support 29 having one end located adjacent to the inlet support 22 and the spacing support 29 having the other end positioned adjacent to the outlet support 23, As shown in FIG.

Through this structure, the salt solution passing through the external heat exchange space 28 is spirally moved by the flow path forming portion 33, so that the time required to pass through the external heat exchange space 28 is increased and the heat exchange is performed more efficiently do. Further, the dyeing passing through the external heat exchange space (28) makes contact with the outer surface of the flow path forming portion (33) to cause heat exchange, thereby increasing the heat transfer area and maximizing the temperature rise efficiency.

In this case, the cooling water is introduced through the steam discharge pipe 32, and the cooling water rises in the inner cylinder 20 while the heat exchange pipe 27 and the external heat exchange The salt solution in the space 28 may be cooled and discharged through the steam inlet pipe 31.
