Description

Splash Grid Filler {SPLASH GRID FILLER}

The present invention relates to a filler that is a filler for a cooling tower, and more particularly, to increase the cooling efficiency and performance of the cooling tower compared to the conventional one by allowing the cooling water injected from the upper direction to be evenly distributed and minimizing the particle size of the cooling water finely. It's all about the Splash Grid Filler.

In general, the cooling tower is a type of heat exchanger that directly cools the water by directly connecting it with outdoor air in order to reuse the cooling water used in the condenser of the refrigerator. The cooling method can be divided into natural ventilation type and forced ventilation type according to the ventilation type. have.

Forced ventilation is used more frequently for air conditioning facilities or general factories, and fillers are placed inside the cooling tower to improve cooling efficiency. This filler has the greatest effect on determining the cooling efficiency of the cooling tower. In addition to determining the size of the cooling tower.

The filler for the cooling tower is usually installed in a housing of the cooling tower composed of a filler assembly having a structure in which a plurality of fillers are stacked.

On the other hand, the filling material for the cooling tower is necessary enough to evenly distribute the lower temperature of the cooling water sprayed from the upper direction of the filler by the spray nozzle for a long time and evenly distribute the lowered coolant sprayed by the spray nozzle or to crush the high temperature coolant sprayed by the spray nozzle. If the above conditions are sufficient, the cooling efficiency of the cooling tower for making low temperature cooling water can be greatly improved and the performance can be improved.

Here, looking at various embodiments of the filler for the cooling tower according to the prior art as follows.

As shown in the example of Figure 6, the plate-shaped filler for other A company cooling tower of the film type made of conventional PVC material (see the lower photo of Figure 6) is provided with a thin film-type filler, but using a plurality of adhesive to attach Due to this, there is a problem that the manufacturing is inconvenient, takes a lot of time to manufacture, and the problem is not easy to clean, the whole structure is flat when the contact with the coolant and foreign matters such as dust and moss accumulate on the surface of each layer There is a problem that is sitting down due to the weight of the weight and because of this short replacement cycle, and because it is difficult to recycle, it has a problem that is not environmentally friendly due to the discharge of environmental hormones due to incineration treatment during disposal.

In addition, in the water distribution test of the conventional film-type A-type filler, when the water is sprayed from the upper center, it shows a distribution diagram of the straight downward type which does not distribute water evenly in the downward direction, but also falls to the lower side. The particles of water also clump together to form a very thick stream of water.

In addition, as shown in the example of Figure 7, the filling material for the other B company cooling tower made of PP material (see the lower left picture of Figure 7) is arranged at equal intervals on the surface of the plate member having a plurality of holes and irregularities formed protruding in the same direction The projections are formed, and the water distribution is tested by spraying water from the upper center of the filler, which also shows a linear downward distribution which does not distribute water evenly in the downward direction. This water stream forms and shows that it is falling.

Further, as shown in the example of Figure 7, the filling material for other C company cooling tower (see the lower right picture of Figure 7) made of PP material is a convex protrusion which is formed zigzag protruding in the transverse direction on the surface of the plate member having a plurality of holes As a result of testing the distribution of water by spraying water from the upper center of the filler, which is an aggregate, it also shows the distribution of the straight down type which does not distribute the water evenly in the downward direction. It shows that they form a thick stream of water together.

Meanwhile, the present applicant has also been presented in the form as shown in the example of FIG. 7 (see the upper right photo of FIG. 7) for the cooling tower filler, which is a mesh-shaped body surface having a plurality of through holes by a planar grid structure. It was configured to form a curved wave-shaped structure in the water, and the water distribution was tested by spraying water from the upper center of the filler, which is an aggregate. Is showing the type of.

That is, the filling material for the cooling tower of the prior art including the various embodiments as described above has a problem that all of them do not effectively make the cooling water in the housing of the cooling tower, and evenly distributed in the downward direction while stagnating the high temperature cooling water for a long time. Since it does not meet the necessary conditions to be sent down or crush the high temperature cooling water, the heat exchange efficiency for cooling is inevitably reduced, and it is not possible to recover heat easily from the condensed stream type water. Of course, the company is facing a situation that cannot improve performance, and only costs material and maintenance costs to prepare an assortment of cooling towers.

The present invention has been made to solve the above-described problems, while the high-temperature cooling water sprayed in the upper direction of the aggregate filling by the injection nozzle, evenly distributed downward in the downward direction, as well as the high temperature cooling water It is an object of the present invention to provide a splash grid filler capable of satisfying the necessary and sufficient conditions for minimizing the crushed particle size.

That is, the present invention is to provide a splash grid filler that can significantly reduce the material cost and maintenance costs required for the cooling tower, while significantly increasing the cooling efficiency and performance of the cooling tower compared to the conventional.

The present invention is disposed in the housing of the cooling tower, the splash grid filler is installed in the lower side of the injection nozzle for injecting high-temperature cooling water,

A rectangular border having a curved wave structure in which a shape that is zigzag-shaped is repeatedly formed with respect to a slope; It is connected to the rectangular border to fill the inner space of the rectangular border to form the front and rear surface of the filler, and arranged diagonally oblique diagonal guide projections at equal intervals, including an oblique lattice linear protrusion formed in an opposite arrangement to be located on the front and rear sides It is characterized by a configuration.

At this time, the oblique grid projections are arranged at equal intervals so that the front oblique guide protrusions are located at the inner side of the rectangular border, and the oblique front projection at both sides connected to the front surface of the rectangular border, and the rear oblique guide protrusion at the inner side of the rectangular border Arranged at equal intervals, but both sides end is connected to the back of the rectangular border and is arranged in the opposite direction to the front oblique guide projection is composed of a rear oblique projection to form a grid structure by mutual contact; The front oblique guide protrusion and the rear oblique guide protrusion may be repeatedly configured to be bent in a zigzag direction to form a surface treatment of a diamond wave array that is opposite to each other on the front and rear surfaces of the filler.

The present invention evenly distributes the high temperature cooling water sprayed in the housing of the cooling tower in the downward direction so that it can be stagnated for a long time on the filling material and can increase the contact area and contact time between the cooling water and the outside air and heat exchange. It can increase the efficiency, and also induce collision due to the crossover of the water flowing down through the surface of the filler, thereby minimizing the particle size of water crushing, and thus recovering the thermal energy possessed by the high temperature cooling water more easily. It can greatly increase the cooling efficiency and performance of the cooling tower compared to the existing.

In addition, the present invention can reduce the material cost and maintenance cost required for the cooling tower can minimize the economic loss, and the side effect of reducing the external size of the cooling tower to reduce the overall manufacturing cost and installation cost of the cooling tower Can be elicited.

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

As shown in Figures 1 to 4, the splash grid filler 100 for a cooling tower according to an embodiment of the present invention is a plate-shaped injection molded product using a PP material, a rectangular border 110 and the rectangular border 110 It is connected to the inner space of the rectangular border to form the front and rear surface of the filler 100, and the obliquely inclined linear guide line (A) (B) is arranged at equal intervals, but on the front and rear sides It consists of a diagonal lattice linear protrusion 120 formed in the opposite arrangement.

The rectangular border 110 has a four-sided surface to have a wave structure that is repeatedly formed bent in a zigzag direction.

At this time, the rectangular border 110 is formed of a substantially rectangular shape, the upper and lower sides and the left and right sides facing each other in the four sides for the surface treatment through the diamond-like wave structure of the diagonal self-forming protrusion 120 is the same Zig-zag curved structure of inclination angle is formed.

Here, the rectangular border 110 will be formed longer than the forming length (L2) of the upper and lower portions in the forming length (L1) according to the bending direction of the left and right portions for the diamond-like wave surface treatment for the filler 100. .

The diagonal grating linear protrusion 120 is arranged at equal intervals to the front oblique guide projection (A) so as to be located on the inner side of the rectangular border 110, the front oblique projections 121 and both ends connected to the front surface of the rectangular border, square Arrange the rear oblique guide protrusions (B) at equal intervals so as to be located at the inner side of the edge 110, but both ends are connected to the back of the rectangular border and are arranged in opposite directions to the front oblique guide protrusions (A) by mutual contact. Consists of a back oblique protrusion 122 to form a lattice structure.

At this time, the diagonal lattice-shaped protrusion 120 which forms the front and rear surfaces of the filler 100 for the cooling tower according to the present invention has a plurality of through-holes due to the cross contact between the front oblique protrusion 121 and the rear oblique protrusion 122. H) is formed, and the through hole H is formed in a diamond shape.

The front oblique guide protrusion (A) of the front oblique protrusion (121) and the oblique guide protrusion (B) of the rear oblique protrusion (122) are configured to be repeatedly formed to be curved in a zigzag direction, and thus the front and rear surfaces of the filler (100). It is desirable to configure the contact surface treatment to have a diamond-like wave arrangement opposite to each other.

That is, if the front surface of the filler 100 to form a structure that protrudes toward the center of the diamond structure, in the back of the filler 100 at the position corresponding to the filler 100 in a form that is recessed toward the center of the diamond structure With respect to the front and back surface of the C), the opposite diamond-like structures form a continuous wave array in which the repeating sequence is repeated.

The front oblique guide protrusion (A) of the front oblique protrusion (121) and the oblique guide protrusion (B) of the rear oblique protrusion (122) are preferably configured to have a thickness of 3 mm to 5 mm, respectively, and most preferably formed with a thickness of 4 mm. It may be desirable.

Here, when the thickness of the front oblique guide protrusion (A) and the rear oblique guide protrusion (B) is less than 3 mm and exceeds 5 mm in thickness, the high temperature coolant is evenly distributed in the downward direction and the high temperature coolant is crushed finely. Since the giving function is inferior and the efficiency of heat exchange and heat recovery is reduced, the cooling efficiency for making low temperature cooling water is inferior.

In addition, the diagonal lattice linear protrusion 120 has a coupling protrusion 123 to enable a plurality of laminated coupling to project the filler 100 of the present invention into an aggregate.

The curved wave structure used in the above-described cooling tower filler 100 of the present invention will have a continuous repeating shape of linear bending.

Referring to the operation of the splash grid filler 100 according to the present invention having such a configuration as follows.

First, the filler 100 of the present invention is composed of a plurality of laminated filler assembly by using a coupling protrusion 123 protruding from the oblique grid-shaped protrusions 120, the filler assembly is installed in the housing of the cooling tower But it is to be installed under the injection nozzle for spraying high temperature cooling water.

At this time, the filler assembly is arranged to be in close contact with the rear oblique protrusion 122 of the filler 100 located in the front and the front oblique protrusion 121 of the filler 100 located in the rear and cross in a mutually opposite arrangement.

The high temperature cooling water supplied into the housing of the cooling tower through the cooling water supply pipe is sprayed to the upper side of the filler assembly having a multi-layered structure by the filler 100 of the present invention through an injection nozzle, wherein each of the filler assemblies is constituting the filler assembly. In the filler 100, the front oblique guide protrusion A of the front oblique protrusion 121 and the rear oblique guide protrusion B of the rear oblique protrusion 122 flow in a downward direction in a direction opposite to each other. And flows downward along the diamond wave surface to reduce the flow rate of the high temperature cooling water and to stay on the surface of the filler 100 for a long time.

Accordingly, the contact area and the contact time between the external air flowing into the filler 100 and the high temperature coolant can be increased to the maximum, thereby exchanging the high temperature coolant with the low temperature coolant and increasing the heat exchange efficiency.

In particular, the front oblique guide projections (A) of the front oblique projections 121 and the rear oblique guide projections (B) of the rear oblique projections (122) guide the hot water to flow downwards, but across the through hole (H). It is guided to flow, and this action can lead to a direct contact between the outside air flowing into the filler assembly through the through-hole (H) and the high temperature cooling water more strongly it is possible to further increase the heat exchange efficiency.

In addition, the high temperature cooling water flowing downward by the diamond wave structure of each filler 100 flows down one diamond surface having a linear structure, but is left, right and lower while passing through an upper portion of the diamond surface. As the direction of the stream of water is divided, the high temperature cooling water sprayed into the continuous distribution of the stream of water flows evenly distributed downward, and this action also increases the heat exchange efficiency.

On the other hand, the coolant of the high temperature is lowered through the surface of each filler 100 flows downward by the cross structure of the front oblique guide protrusion (A) and the rear oblique guide protrusion (B), the collision is caused by the mutual cross In this case, the water stream is broken by the collision of water streams, and the water is continuously broken down. Therefore, the water stream passing downward from the upper side of the filler 100 minimizes the particle size and is evenly distributed. It will fall into shape and fall off.

Accordingly, it is possible to more easily recover the thermal energy possessed by the high temperature cooling water, thereby making the cooling water at low temperature, and the high temperature cooling water can be cooled by the low temperature cooling water with excellent cooling efficiency.

On the other hand, Figure 5 is a photograph shown to help the understanding of the present invention, comprising a filler 100 for the cooling tower according to the present invention constitutes a filler assembly and the result of testing the distribution of water by spraying water in the upper direction center The distribution of water in the first and second stages of the filler assembly was tested.

As shown in FIG. 5, the water injected into the filler 100 according to the present invention shows that the water is evenly distributed over the entire downward portion of the filler for the same reason as described above, and water particles are minimized. It is showing that it is falling in the form of granules of very small water particles, not in the form of the existing thick water stream.

As can be seen from the distribution test results of such water, the cooling tower filler 100 according to the present invention has the necessary sufficient conditions as a filler (filler) for improving the cooling efficiency described in the background art of the detailed description by the overall structural improvement As a result, it is possible to exert an operation force having a very excellent cooling efficiency that can not be compared with the fillers of the prior art.
