Description

Cooling tower and system having the same

The present invention relates to a cooling tower and a cooling system including the same, and more particularly, to a cooling tower with improved performance in terms of maintenance, and a cooling system including the same.

The cooling tower is a heat exchange device that directly connects and cools the cooling water used in the condenser of the refrigerator to re-use it with outdoor air.

Cooling towers are largely divided into an open type that lowers the temperature of the cooling water by heat transfer generated when the cooling water and outside air contact, and a closed type that lowers the temperature of the cooling water by using the latent heat of evaporation of evaporation water sprayed on the cooling water in a closed circuit.

Among them, the open type cooling tower is again divided into a counter flow type cooling tower, a cross flow type cooling tower, and a non-powered cooling tower, among which the cross flow type cooling tower can be cooled as follows.

A cross-flow cooling tower is provided with a filler in the body, an upper water tank is provided on the upper side of the filler, a cooling water supply pipe is connected to the upper water tank, and the cooling water supplied through the cooling water supply pipe is sprayed to the upper water tank. A plurality of through-holes are formed in the bottom surface of the upper water tank, and accordingly, the cooling water discharged through the through-holes falls to the filler provided at the lower side and moves along the filler. And, the cooling water introduced into the filler material is heat-exchanged and cooled while contacting the air passing through the filler material.

In general, cooling towers having such a structure may have a structure in which a plurality of cooling towers are arranged according to the total capacity required at the place where they are installed as shown in FIG. 1. For example, in the case of a total capacity of 80ct, four cooling towers 10 having an individual capacity of 20ct may be gathered to form a cooling system 1 having a horizontal arrangement structure. In FIG. 1, four cooling towers are arranged in a single layer, but may be arranged in multiple stages of two or more depending on the space.

As for the filler 12, the detachable method may be a method in which unit units are attached to a hanger H formed in two rows as shown in FIG. 2. It may be a so-called hanging method. This causes the following problems.

As for the filler, hundreds of unit units may form a set and be mounted on the cooling tower. Generally, the filler is made of PVC. The thickness of the unit unit may be approximately 0.2 to 0.6T, and the weight may be approximately 500g to 2kg. One set weighs approximately several hundred kg.

The filler 12 needs to be replaced due to lifespan, curing due to UV exposure, cooling water quality management problems, and generation of sludge when continuously used. A replacement process is required in which a manager (not shown) enters the cooling tower 10 through the manager door D, removes unit units one by one from the hanger H, and inserts new unit units.

However, in the case of the cooling tower 10 arranged in the middle in the horizontal arrangement structure as shown in FIG. 1, replacement of the filler 12 is very difficult. This is because it involves separating the corresponding cooling tower 10 from other cooling towers in order to secure a working space.

Of the four, the leftmost and the rightmost cooling towers have one wall exposed, so it is possible to replace the filler using the exposed wall, but in the middle two, both walls are completely blocked by adjacent cooling towers, so the adjacent cooling towers are separated. Without it, replacement is almost impossible.

Although it may be assumed that the filler material is removed from the top of the cooling tower, it becomes difficult to secure a working space when the cooling towers are stacked in multiple stages as described above.

After all, the existing filler replacement method excessively increases the cost and time. Since the direction (ID) in which outside air flows into the filler material is orthogonal to the direction in which the cooling towers are arranged (that is, because the extension direction of the hanger coincides with the direction in which the cooling towers are arranged), the above problem is the same in the conventional hanging method. Is inevitably accompanied.

The inventor of the present invention came to complete the present invention after a long study and trial and error in order to solve the more efficient maintenance of the filler.

An embodiment of the present invention provides a cooling tower capable of efficiently maintaining and replacing cooling tower components, and a cooling system including the same.

3 and 4, the cooling tower 10 according to an embodiment of the present invention basically includes a main body housing 11, a filler 12, an upper water tank 13, a lower water tank 14, and an air inlet. (15) and may include an air outlet (16).

The air inlet port is a place where external air is introduced, and may have an open structure. Although the drawing shows that the air inlet is provided on the filler side, the air inlet may be provided in the main body housing due to its role.

In the present invention, the cooling system 1 is constructed by arranging one or more cooling towers 10. At this time, the cooling towers may be configured in a planar arrangement. The cooling towers correspond to the direction perpendicular to the direction of the air inlet 15 (corresponding to the reference numeral ID shown in Fig. 2) (corresponding to the reference numeral LD shown in Fig. 2) of the air inlet 15 through which external air is introduced into the interior of the main body housing 11. Can be arranged as a). The cooling tower 10 is preferably a cross-flow type cooling tower, but the present invention is not limited thereto and may also be applied to a counter-current type.

In the present invention, the cooling water is converted into high-temperature cooling water by a high-temperature condenser (not shown), and then heat-exchanged with air in the filler 12 to be continuously recirculated to the low-temperature cooling water, which is circulated in a cross-flow type cooling tower. have.

The main body housing 11 forms at least a part of the outer shape of the cooling tower 10 and may allow a space to be formed inside.

For example, the main body housing 11 may form a part of the outer shape of the cooling tower 10 when the filler 12 is the filler module 12a. The remaining part may be formed by a filler module. It will be described later.

As another example, the main body housing 11 may form the entire outer shape of the cooling tower 10 when the filler 12 is a filler cartridge 12b. In this case, the main body housing 11 may include an upper water tank 13 and a lower water tank 14 to be described later.

The main body housing 11 may be configured such that an air outlet 16, which will be described later, is formed on an upper surface, and a filler module 12a is detachable or a filler cartridge 12b is inserted or removed on both sides.

The main body housing 11 may be provided with an administrator door D that allows administrators to enter and exit the lower side.

The filler 12 is provided on one side or both sides of the main body housing 11 and is configured to heat-exchange the cooling water with external air.

The filler 12 according to the embodiment of the present invention is detachably formed from the main body housing 11 in the direction of the air inlet 15 through which external air is introduced into the interior of the main body housing 11. The direction of the air inlet may be a direction of an opening formed for air inflow. That is, it may be a direction in which outside air is introduced.

The direction of the air inlet may be a reference numeral ID shown in FIG. 2. The arrangement direction of the unit units constituting the filler is also the same as the direction described above in FIG. 2. This is because it is arranged according to the direction of the air inlet. However, according to the embodiment of the present invention, instead of the hanging method, the filler is configured as an integral type that can be separated from the main body. There are a module type 12a and a cartridge type 12b as an integral type. It will be described later.

Through this structure, the cooling tower 10 of the present invention can efficiently replace the cooling tower components even when the cooling system 1 is built, and there is an effect of reducing maintenance costs.

The filler 12 may be formed by overlapping a plurality of unit units, and heat exchange while cooling water introduced from the upper water tank 13 and external air introduced from the air inlet 15 are in contact with each other to cool the cooling water. The unit units may be made of various materials such as wood, synthetic resin, thin metal plate, or asbestos plate, and are not limited to any specific material.

The filler 12 may be formed of a filler module 12a as shown in FIG. 3, and may be formed of a filler cartridge 12b as shown in FIG. 4.

First, an embodiment in which the filler 12 is formed of the filler module 12a will be described.

Referring to FIG. 3, the filler module 12a may include a filler housing 121a, an upper water tank 13, a lower water tank 14, and an air inlet 15. That is, the cooling tower 10 according to an embodiment of the present invention may form a filler module 12a by being surrounded by a filler housing 121a after a plurality of fillers 12 composed of a plurality of unit units are clustered. have.

Here, the upper water tank 13 and the lower water tank 14 are detachably formed so as to be separated from the main body housing 11 together with the filler 12 and the filler housing 121a, and structurally Can be separated.

In this case, the main body housing 11 and the filler housing 121a may be fastened by a bolting fastening method, a clip fastening method, a jig fastening method, and the like to be fixed or separated. Due to the characteristics of the cooling tower, it is preferable that the main body housing and the filler housing are sufficiently tightly coupled to each other to secure cooling capacity.

Therefore, the cooling tower 10 according to an embodiment of the present invention is constructed in a modular form so that the part in which the filler 12 is installed is separated from the cooling tower 10, and is replaced regardless of the manner in which it is assembled with adjacent cooling towers. By configuring in this way, cooling tower components can be efficiently replaced and maintenance costs are reduced. Think of the filling material being replaced in a direction orthogonal to the direction of the cooling towers.

The filler housing 121a may be detachably formed separately from the main body housing 11 and may be constructed in a modular form together with the filler 12. That is, the filler housing 121a is formed to surround the filler 12, and may be formed to accommodate the upper water tank 13 and the lower water tank 14.

As shown in FIG. 3B, the filler housing may have a casing structure that allows the upper filler and the lower filler to be separated. Thus, the lower filler may be first coupled to the body housing, and then, the upper filler may be assembled in the order of being coupled to the body housing.

The housing part for the upper filler and the housing part for the lower filler may have a structure for fastening or separating from each other. It may be a bolting fastening, a clip fastening, and a jig fastening method. Although it may have a structure in which the upper and lower two fillers are casing at once, the upper and lower separable casing structure as described above increases the convenience of storage and transport of the filler module. On the other hand, when considering the above-described assembly sequence, it is preferable that the fastening method is clip fastening. A method of pushing the bottom of the last joined portion in close contact with the uppermost portion of the joined portion immediately before, that is, a clip fastening method that can be coupled in a sliding manner may be applied. For this, a clip structure may be provided on each of the bottom and top portions.

Next, an embodiment in which the filler 12 is formed of the filler cartridge 12b will be described.

Referring to FIG. 4, unlike the filler module 12a described above, the filler cartridge 12b does not include the upper water tank 13 and the lower water tank 14, but may include only the filler housing, that is, the filler frame 121b. . When the air inlet is provided on the filler side rather than the body side, as shown in the drawing, the filler cartridge may further include an air inlet.

That is, in the cooling tower 10 according to another embodiment of the present invention, a plurality of fillers 12 composed of several unit units are clustered and fixed by the filler frame 121b to form a filler cartridge 12b. have.

Here, the upper water tank 13 and the lower water tank 14 are formed in the main body housing 11, and the filler housing, that is, the filler frame 121b, is separated from the main body housing 11 with only the filler 12 and can be attached and detached. Is formed, it can be configured in a cartridge manner with respect to the main body housing (11). That is, the filler cartridge is detached from the space provided inside the main body housing.

The filler frame 121b may be formed in a frame structure formed at the corners of the filler 12 to form a frame to serve as a filler housing.

As described above, the cooling tower 10 according to an embodiment of the present invention can efficiently replace the cooling tower components by configuring the replacement method of the filler 12 in a cartridge method and replacing it without interference with adjacent cooling towers. There is an effect of reducing maintenance cost.

Meanwhile, referring to FIGS. 4B and 4C, the filler cartridge 12b may be formed by being divided into a plurality of unit cartridges. It may be formed to be divided up and down and/or left and right to be provided in close contact with each other or to be stacked.

In FIG. 4B, an embodiment in which the filler cartridge is divided into left and right two unit cartridges 12b_L and 12b_R is shown. In FIG. 4C, an embodiment in which the filler cartridge is divided into four unit cartridges 12b_LD and 12b_RD is shown. In the case of FIG. 4B, the size of the unit cartridge corresponds to 1/2 of the full scale of the existing filler. In the case of FIG. 4C, the size of the unit cartridge corresponds to 1/4 of the full scale of the existing filler.

When multiple cartridge units are used, cost reduction is possible by selectively replacing only cartridges with severe contamination.

In particular, as in the case of Figure 4c, when the cartridge unit is separated up and down, the contamination of the fillers 12b_LU and 12b_RU disposed on the upper side is more severe than the fillers 12b_LD and 12b_RD disposed on the lower side, so these Bay can be optionally replaced. This is because, when the heat exchange method is a cross-flow type, considering the direction of the outside air entering from the outside to the direction of the cooling water falling from the top, the amount of filler disposed above is relatively higher. This implements a partial replacement of the filler material 12 rather than a full replacement. There is an effect of improving the durability and durability of the filler 12 and reducing the driving cost. That is, the cooling tower 10 according to an embodiment of the present invention further subdivides the filler cartridge 121b into upper and lower units and/or left and right units, thereby selectively replacing only the highly polluted filler, and efficient cooling tower operation and maintenance. It can be operated as a cost saving effect.

Meanwhile, when the filler cartridge is formed of a plurality of unit cartridges, a structure for fastening and separating the unit cartridges may be provided. It may be a bolting fastening, a clip fastening, and a jig fastening method. In this case, a lower level of fastening force than the above-described fastening force in FIG. 3 is sufficient. In FIG. 3, the fastening force is directly connected to the cooling capacity of the cooling tower, but the fastening force between the unit cartridges is sufficient if they are not separated from each other.

As described above, the air inlet may be provided on the body housing side or on the filler side, but in the modular type according to the embodiment of the present invention, it is provided on the filler side, and in the cartridge type according to the embodiment of the present invention, it is provided on the body side. It is preferable to be provided. The modular type is for the purpose of complete structural separation, and the air inlet is provided to be structurally separated. Since the cartridge type can be divided into unit cartridges, it is simple in design to provide a single air inlet on the body side regardless of the number of unit cartridges.

With continued reference to FIGS. 3 to 4, the upper water tank 13 may supply cooling water from the top of the filler 12 and may be formed in a container shape to accommodate the cooling water.

The upper water tank 13 may be provided on the upper side of the filler 12, and for this purpose, a base plate (not shown) may be formed to correspond to the upper shape of the filler 12, and a plurality of distributions to the base plate Holes (not shown) may be formed.

The cooling water accommodated in the upper water tank 13 is discharged to the lower filler 12 along the distribution hole and falls to the top of the filler 12, and the falling coolant may flow downward along the filler 12.

Here, a plurality of separate spray nozzles (not shown) may be additionally provided in each distribution hole for more efficient spraying of the coolant, and the spray nozzles may be provided below the upper water tank.

The upper water tank 13 may be connected to a cooling water supply pipe (not shown) forming a moving path of the cooling water. Among these cooling water supply pipes, the cooling water supply pipe provided in the main body housing 11 may be formed inside the main body housing 11 so as not to be exposed to the outside.

The upper water tank 13 may be supplied with cooling water through a cooling water distribution device (not shown; for example, a flow control valve) connected to the cooling water supply pipe.

The lower water tank 14 may accommodate the cooling water that has passed the filler 12 and the bottom of the filler 12.

The lower water tank 14 may be formed in a container shape to collect coolant that has passed through the filler 12 and may be formed to correspond to the bottom surface of the filler 12.

The air inlet 15 may introduce external air into the main body housing 11 from the outside, and may be formed on both sides of the main housing 11, wherein the air inlet 15 is at one side of the filler 12 That is, it may be formed on the filler housing 121a.

The air inlet 15 may be provided with a louver (not shown) that guides the incoming external air, and the air outlet 16 allows external air supplied from the air inlet 15 to be supplied from the main body housing 11. It can be discharged to the upper side, it can be formed in the main body housing (11).

The air outlet 16 may have a fan, and the fan may discharge air inside the main body housing 11 to the upper and outer sides of the main body housing 11.

As described above, the cooling tower 10 according to an embodiment of the present invention is constructed in a modular form so that the part in which the filler is installed is separated from the cooling tower (filling material module; 12a) and replaced regardless of the method of assembly with the adjacent cooling tower. By configuring it as a cooling tower, it is possible to efficiently replace parts and reduce maintenance costs.

In addition, the cooling tower 10 according to an embodiment of the present invention configures the replacement method of the filler 12 in a cartridge method (filler cartridge; 12b) and is configured in a method of replacing without interference with adjacent cooling towers, so that the cooling tower components are efficiently used. It can be replaced with, and has the effect of reducing maintenance cost.
