Description

Filler for cooling tower to improve moisture distribution and strength {Filler for Cooling Tower to improve capability of water distribution and to enhance strength}

The present invention relates to a filler installed in a cooling tower, which is a cooling water circulation cooling treatment device. In particular, the upper and lower portions of the filler are reinforced to prevent water from being crushed to improve moisture distribution and strength. The present invention relates to an improved cooling tower filler.

Heat generated from an air conditioning system or an industrial heat exchanger, etc., must be released until it maintains an appropriate temperature for cooling the room or cooling the equipment. As a device for removing such heat, a cooling tower is installed and operated. The cooling tower circulates the cooling water to directly or indirectly contact the surrounding atmosphere to obtain a cooling effect. At this time, an important factor affecting the cooling performance is the contact time and the contact area of the coolant and air, and various types of fillers are installed in the cooling tower to extend the contact time of the coolant and the air and widen the contact area.

In particular, the filler is formed of a ridge of the same structure as the applicant filed by the applicant (Cooling plate for cooling tower: Application No. 10-1998-014607) to extend the contact time of the cooling water and air and to expand the contact area. .

The cooling tower for the cooling tower of the above application, that is, the ridge formed in the plate body portion of the filler is formed in a wave shape of about 60 degrees with respect to the plate surface, the length ratio (A: B) of the ridge protrusion to achieve 1: 1.5. It is formed, and the curved portion of the ridge is rounded.

Accordingly, the coolant dispensed from the top of the filler flows at an angle of about 15 degrees to the louver side with respect to the vertical longitudinal axis as it flows down along the filler plate surface, but as a result, the coolant flowing through the deflection by the air pressure of the intake air is consequently They fall vertically and greatly expand the contact area between the coolant and the air, increasing the overall efficiency.

On the other hand, the filler is provided with a gap maintaining protrusion and a pipe through-hole forming portion for supporting the filler having the same practical application as the applicant has filed (Applicant No. 20-1986-012523 for cooling tower). Triangular grooves are formed at the edge portions of the gap holding protrusions, and two protrusions are formed on the rear surface of the gap holding protrusions to alternately contact each other with the triangular grooves of the other fillers. At this time, the interval between the triangular grooves and the interval between the two protrusions abutting are formed equally.

In addition, both sides of the filler is formed so that the louver portion for suctioning and inducing external air and the eliminator portion for preventing the cooled coolant from scattering to the outside have an inclined cross section of approximately 40 degrees. At this time, the louver portion and the eliminator portion formed integrally with one filler and the other filler stacked on each other are formed to alternately contact each other when the fillers are stacked.

When the fillers having the above configuration are laminated to each other, the protrusions formed on the rear surface of the other fillers are aligned with the triangular grooves formed in the gap maintaining protrusions, and thus the fillers to be stacked maintain a predetermined distance from each other.

In addition, the louver part and the eliminator part integrally formed in one filler and the other filler stacked on each other alternately contact when the fillers are stacked on each other, so that the laminated surface is formed in a honeycomb shape when viewed in cross section. The honeycomb structure is formed into a thin plate to reinforce the strength of the filler which is easily bent. At this time, since the louver part and the eliminator part are each formed with an inclined section of approximately 40 degrees, the louver part prevents the cooling water flowing through the filler from splashing out. On the eliminator part, the coolant heading toward the eliminator part by the air pressure of the intake air and Since the coolant in the air collides with the inclined surface of the eliminator, the coolant flows down and only the air escapes along the wide passage.

In this way, the lamination work can be easily and accurately laminated while maintaining the predetermined distance by the gap holding protrusion, and the strength of the side surface is reinforced by the louver part and the eliminator part formed integrally with the side end part of the filler material. This can be prevented by loads of coolant flowing along the filler or by lateral deformation due to filler fixation.

However, the conventional laminated tower filler for cooling towers is weak in strength of the upper and lower sections, so that the filler is positioned in the cooling tower at the lower end of the filler by the support or when the filler is positioned in the cooling tower by the filler support pipe. Deformation is likely to occur at the top and bottom of the filler material. In addition, in the upper and lower portions of the filler, deformation due to the load of the cooling water distributed in the distribution plate and flowing down the filler is also likely to occur.

As shown in FIGS. 1C and 1D, when the top and bottom portions of the filler are deformed and the cross-sectional shape thereof becomes bent, the gap between the fillers in the top and bottom portions of the filler is not properly maintained, and thus the coolant distributed in the distribution plate The overall moisture distribution is deteriorated, such as a filler that does not flow evenly distributed on both sides of the filler and only flows to one side of the filler, or often a coolant does not flow at all.

As such, the deterioration of the moisture distribution greatly reduces the area of contact between the coolant and the air sucked from the outside, thereby failing to properly exhibit the cooling function, which is the original function of the cooling tower, and as a result, the overall cooling efficiency is lowered.

The present invention is to solve the above disadvantages, an object of the present invention is to form a strength reinforcing portion of the shape similar to the louver portion or the eliminator portion formed integrally with the upper end portion and the lower end portion of the conventional filler. Thus, the strength of the upper and lower portions of the filler is reinforced.

Another object of the present invention is to improve the overall moisture distribution, such as to distribute the cooling water more evenly to each of all the fillers laminated by forming the strength reinforcing portion integrally to the upper and lower portions of the filler.

The present invention relates to a filler for a cooling tower, and more particularly, to a cooling tower filler having improved moisture distribution and strength.

A feature of the present invention is for a cooling tower in which an intermediate plate portion in which coolant is in contact with air, a louver portion at one side end for sucking and inducing external air, and an eliminator portion at the other side end to prevent scattering of the cooling water are integrally formed. In the filling material, when the top and bottom strength reinforcing parts of the shape similar to the louver part or the eliminator part are integrally formed on the top and bottom parts of the filling material, the cross-sectional shape has a honeycomb structure when laminating the filling material on one side and the filling material on the other side. It is to strengthen the filler to improve the overall moisture distribution.

1A and 1B are views illustrating a state in which a cooling tower and a filler are stacked in a state in which the filler of the present invention is stacked and mounted.

Figure 2a and Figure 2b is a view showing the type A filler and the type B filler of the present invention, respectively. Referring to the drawings the filler of the present invention in more detail as follows.

The A-type fillers and the B-type fillers of the present invention are both formed at the center portion, and are formed at both end portions of the corrugated plate portions 10a and 10b and substantially at both ends of the corrugated plate portions 10a and 10b. Louver portions 20a and 20b and the eliminator portions 30a and 30b formed integrally with each other, and upper strength reinforcing portions 40a and integrally formed on the upper and lower portions of the corrugated plate portions 10a and 10b, respectively. 40b) and lower strength reinforcing parts 50a and 50b.

The corrugated plate body portions 10a and 10b are portions in which the intake air induced and sucked from the outside are mainly in contact with the coolant, which is filed by the present applicant (cooling plate for cooling tower: application number 10-1998-014607, complex cooling for cooling tower). Wheel: Application No. 20-1986-012523) has a shape almost similar to the patent and practical configuration.

This will be described in more detail with reference to FIGS. 3 to 4C as follows.

The corrugated plate portions 10a and 10b of the filler form the ridges 12a and 12b at a wave angle of about 60 degrees with respect to the plate surface, and the length ratios A: B of the ridges 12a and 12b are 1. It is formed to achieve 1.5, and is formed by forming the bent portions (14a, 14b) of the ridges (12a, 12b) round.

Accordingly, the coolant dispensed from the upper part of the filler flows downward at an angle of about 15 degrees toward the louver portions 20a and 20b with respect to the vertical longitudinal axis when the corrugated plate portions 10a and 10b of the filler flow, and the air pressure of the intake air flows. Pushes the deflected coolant in a direction opposite to the deflected direction, causing the coolant to fall along the vertical longitudinal axis.

Therefore, the contact area of the cooling water and the air can be extended, and the contact area can be greatly enlarged, and the overall efficiency can be increased.

In this case, instead of forming the plate body portion of the filler as a wavy ridge, it may be formed as a simple circular ledge, a rectangular ledge, a wavy ridge, and the like, and the length ratio of the ridge may be variously selected.

In addition, the corrugated plate body portions 10a and 10b of the filler are spaced apart at predetermined intervals, respectively, to form the gap maintaining protrusions 60a and 60b and the pipe support hole forming portions 70a and 70b for supporting the filler.

Referring to Figures 4a to 4c will be described in more detail the gap holding projection as follows.

The gap holding protrusions 60a and 60b form triangular grooves 62a, 62a ', 62b and 62b' at their edges, and the triangular grooves 62a, 62a ', 62b and 62b at their root portions. Two protrusions 64a, 64a ', 64b, and 64b' projecting to the rear portion are formed by being spaced apart at the same interval between ').

Accordingly, when laminating the A-type fillers and the B-type fillers together, the triangular grooves 62b and 62b 'formed at the edges of the B-shaped fillers 60b and the A-shaped fillers 60a are formed. The two protrusions (64a, 64a ') formed in the root portion of the fitting to match each other.

Therefore, when the A-type filler and the B-type filler are sequentially stacked alternately, the A-type filler and the B-type filler always maintain a constant distance from each other.

On the other hand, both side end portions of the A-type filler and the B-type filler, respectively, louver portions 20a and 20b for suctioning and inducing external air, and eliminator portions 30a and 30b for preventing cooling water from scattering to the outside. Each of which is formed integrally, which has a shape almost similar to the practical configuration filed by the present applicant (complex wheel for cooling tower: Application No. 20-1986-012523).

This will be described in more detail with reference to FIGS. 5A to 5B.

The louver portions 20a and 20b and the eliminator portions 30a and 30b which are integrally formed at both side end portions of the A-type filler and the B-type filler are formed to have inclined cross sections of approximately 40 degrees, respectively.

In addition, the louver portion 20a and the eliminator portion 30a of the A-type filler are each formed to be bent in the order of ridge-floor-gol-maru-san-maru-gol-maru-san-, ..... And, the louver portion 20b and the eliminator portion 30b of the B-type filler laminated with the A-type filler are bone-maru-san-maru-gol-maru-san-maru-gol-, ... By forming bent in the order of ..., when the A-type filler and the B-type filler are laminated alternately with each other, the cross-sectional shape of the louver portions 20a and 20b stacked on each other and the eliminator portions 30a and 30b stacked on each other The cross-sectional shape of the) has a honeycomb structure.

In addition, the abutments (or small grooves) 22a, 22b, 32a, and 32b of the louver portions 20a and 20b or the radiators and the valley portions of the eliminator portions 30a and 30b are formed to be constant, respectively. When the B-type fillers are stacked on each other, the small protrusions (or small grooves) 22a and 32a and the louvers of the B-type fillers respectively formed on the hills and valleys of the louver portion 20a or the eliminator portion 30a of the A-type filler. By fitting the small grooves (or the small protrusions) 22b and 32b respectively formed in the hills and valleys of the portion 20b or the eliminator portion 30b, the lamination joining surface is more robust while the lamination of the filler is easy. To lose.

The side end cross-sectional shape formed by the stacked fillers in this manner forms a honeycomb structure, thereby reinforcing the lateral strength of the filler that is easily formed and bent into thin plates.

In addition, since the louver portions 20a and 20b and the eliminator portions 30a and 30b are formed in inclined cross sections of approximately 40 degrees, respectively, the louver portions 20a and 20b are sucked and guided by the coolant flowing through the filler and externally. The air can be quickly cooled by enhancing the contact of the air, and the coolant which is pushed toward the eliminator part by the air pressure of the intake air and the coolant contained in the air from the eliminator parts 30a and 30b side By hitting the inclined surface it is possible to prevent the coolant to flow down such that the coolant flows down and only the air escapes along the wide passage.

In particular, the upper and lower portions of the A-type filler and the B-type filler, similar to the louver portions 20a and 20b or the eliminator portions 30a and 30b of the side ends of the filler, the upper and lower strength reinforcement portions 40a and 40b. And 50a and 50b are formed integrally with each other.

This will be described in more detail with reference to FIGS. 6A to 6F as follows.

The upper and lower strength reinforcement portions 40a and 50a formed at the upper and lower portions of the A-type filler, respectively, and the upper and lower strength reinforcement portions 40b and 50b, respectively, are formed at the upper and lower portions of the B-type filler. When the A-type filler and the B-type filler are continuously stacked alternately with each other, they are formed to alternate with each other. In other words, the upper and lower strength reinforcing portions (40a, 50a) formed on the upper and lower portions of the A-type filler, respectively, acid-maru-gol-maru-san-maru-gol-maru-san-, ... And the upper and lower strength reinforcing portions 40b and 50b formed in the upper and lower portions of the B-type filler, respectively, in the order of bone-maru-san-maru-gol-maru-san-maru-gol- When the fillers are stacked together, the top and bottom strength reinforcement parts 40a and 50a of the A-type fillers and the top and bottom strength reinforcement parts 40b and 50b of the B-type fillers are formed in the order of. Each cross-sectional shape formed by) has a honeycomb structure.

In addition, each of the peaks and valleys of the upper and lower strength reinforcing portions 40a, 40b, 50a, and 50b of the A-type fillers and the B-type fillers serve as contact surfaces when laminating the A-type fillers and the B-type fillers. Small protrusions (or small grooves) 42a, 42b, 52a, and 52b are respectively spaced apart at predetermined intervals to form a continuous portion. As a result, when the A-type filler and the B-type filler are laminated to each other, the small protrusions (or the small grooves) 42a and 52a and the B-type fillers respectively formed in the hills and valleys of the strength reinforcing portions 40a and 50a of the A-type filler. The small grooves (or small protrusions) 42b and 52b formed at the peaks and valleys of the strength reinforcing portions 40b and 50b, respectively, are adapted to facilitate the lamination of the filler and to further strengthen the laminated joint surface. .

In addition, as described above, the upper cross-sectional shape and the lower cross-sectional shape of the laminated filler are each formed in a honeycomb structure to support the laminated filler by the support pipe passing through the through hole or when supporting the bottom of the laminated filler by the support. By strengthening the strength of the upper portion and the lower portion of the filler is easy to be formed to bend, so that the top portion and the lower portion of the filler to maintain a firm and stable form without deformation such as bending.

When explaining the form of the upper and lower strength reinforcement in more detail as follows.

The strength reinforcing portions 40a, 50a, 40b, 50b are formed of upper portions 44a, 54a, 44b, 54b, middle portions 46a, 56a, 46b, 56b, and lower portions 48a, 58a, 48b, 58b. In this case, the intermediate parts 46a, 56a, 46b, and 56b are formed to have an inclined cross section at an angle with respect to the vertical longitudinal axis.

At this time, the middle portion (46a, 56a, 46b, 56b) of the strength reinforcing portion has a configuration similar to the distribution plate of the patent filed by the applicant (cooling tower for cooling tower: Application No. 10-1998-014606).

This will be described in more detail with reference to FIGS. 6E and 6F as follows.

That is, when the middle portions 46a and 56a of the strength reinforcing portions 40a and 50a of the A-type filler are formed in an inclined section of approximately 30 degrees counterclockwise with respect to the vertical longitudinal axis, the strength reinforcing portions 40b of the B-type filler The intermediate portions 46b and 56b of 50b are formed at an inclined section of approximately 30 degrees clockwise with respect to the vertical longitudinal axis.

Accordingly, when the A-type filler and the B-type filler are laminated, the middle portions 46a and 56a of the strength reinforcing portions 40a and 50a of the A-type filler and the middle portion 46b of the strength reinforcing portions 40b and 50b of the B-type filler 56b) is aligned in a staggered direction.

In addition, the strength reinforcing portion (40a, 50a) of the A-type filler is formed in the shape of the waveform of the order of the acid-floor-gol-maru-acid-maru-gol-maru-acid-, ..... Strength reinforcing portion (40b, 50b) of the B-type filler is formed in the shape of the waveform of the order of bone-floor-mountain-gol-floor-mountain-maru-gol-, ...... Small protrusions (or small long grooves) 43a, 53a, 43b, 53b are continuously formed at regular intervals, and the protrusions and valleys have small protrusions (or small grooves) 42a, 52a, 42b, 52b of predetermined shapes. Form.

As such, the intermediate portions 46a and 46b of the upper strength reinforcing portions 40a and 40b are stacked while being alternately stacked in an X-shape, and the small protrusions (small long grooves) 43a and 43b are formed in the floor portion, The cooling water dispensed from the upper portion of the can prevent the agglomeration or scattering phenomenon, it is not affected by the suction air induced and drawn through the flow air or louver portion by the fan it is possible to better distribute the cooling water.

In addition, when the fillers are laminated to each other, the small protrusions (or small grooves) 42a and 52a formed at the peaks of the strength reinforcing portions 40a and 50a of the A-type filler are formed in the strength reinforcing portions 40b and 50b of the B-type filler. By making it fit and coupled with the small grooves (or the small projections) 42b and 52b formed in the valleys, the lamination work of the filler is facilitated and the lamination engagement surface of the strength reinforcing portion is firm.

On the other hand, the upper portion (44a, 44b) of the upper strength reinforcing portion (40a, 40b) is formed to have a waveform cross-section similar to the middle portion (46a, 46b), the lower portion (48a, 48b) is a corrugated plate body portion (10a, 10b) ) Is formed in a straight shape to make a soft connection with. Similarly, the upper portions 54a and 54b of the lower strength reinforcing portions 50a and 50b are formed in a straight shape so as to form a smooth connection with the corrugated plate portions 10a and 10b, and the lower portions 58a and 58b are the middle portions 56a and 50b. Similarly to 56b), it is formed to have a waveform cross section.

By forming the shape of the strength reinforcing portion of the fillers as described above, it is possible to reinforce the strength of the upper and lower portions of the filler, as well as to distribute the cooling water supplied from the distribution plate uniformly to both sides of the filler for each of the laminated filler. have.

By distributing the coolant evenly to each of the fillers, the contact area between the suction air and the intake air drawn from the outside through the louver side can be secured sufficiently to prevent the cooling efficiency of the cooling tower from being lowered. have.

As described above, the louver portion and the eliminator portion are integrally formed at the side ends of the A-type filler and the B-type filler, and the strength reinforcement portions are formed at the upper and lower portions, respectively, and the A-type filler and the B-type filler are alternately formed. In the case of continuous lamination, as shown in FIG. 1B, the side end cross section and the top and bottom cross sections of the filler have a honeycomb structure.
