Here, all of the cooling water introduced into the heat exchange filler 160 flows along the wall surface of the filler plate 163. Since the filling plate 163 has a curved shape, the coolant introduced into the first heat exchange passage 161 and the second heat exchange passage 165 must be a wall surface of the filler plate, that is, the first heat exchanger. It flows down along the inner wall surface of the flow path 161 and the second heat exchange flow path (165).

In addition, a lower portion of the cooling water distribution device 115 is provided with the heat exchange filler 160 so that the discharged high temperature cooling water flows downward. In addition, a lower filler 150 is provided below the heat exchange filler.

As the external air introduced through the first air inlet 117 formed in the lower portion of the main body 110 passes through the lower filler material 150 to exchange heat with the cooling water, the cooling water is discharged downward and humidified outside. Air is introduced into the heat exchange filler 160.

At this time, the humidified external air introduced into the first heat exchange passage 161 of the heat exchange filler 160 is directly contacted with the high temperature cooling water, and is heat-exchanged, and the humidified external air introduced into the second heat exchange passage 165. Is heated through indirect heat exchange with the cooling water flowing through the first heat exchange passage 161 to be in a dry state.

Thereafter, the air passing through the first heat exchange passage 161 and the air passing through the second heat exchange passage 165 are mixed with each other and discharged to the upper portion of the main body.

On the other hand, looking at the overall configuration of the anti-smoke smoke-resistant cooling tower according to a preferred embodiment of the present invention, the cylinder 111 is opened on the upper portion of the main body 110 forming the body.

In addition, a blowing fan 112 is provided inside the cylinder 111, and the air inside the main body 110 is discharged out through the cylinder 111 as the blowing fan 112 rotates.

The blower fan 112 is rotated by the rotational force generated by the motor 112a, and the rotational force generated by the motor 112a is transmitted through the power transmission device 112b, for example, the V-belt and the pulley. It is delivered to the blowing fan 112.

In addition, a cooling water distribution device 115 is provided below the blower fan 112 inside the main body 110, and the cooling water distribution device 115 discharges high temperature cooling water. The cooling water distribution device 115 includes a nozzle 115b for distributing the cooling water.

A flange 115a is formed at a side of the main body 110 to supply high temperature coolant to the coolant distribution device 115 from the outside.

In addition, the filler 160 for heat exchange is provided below the cooling water distribution device 115. Here, the heat exchange filler 160 is formed to have a predetermined height in the vertical direction, it may be provided in a horizontal direction over the entire inside of the main body 110.

In addition, a flow path is formed in the heat exchange filler 160 in an up and down direction, and the coolant discharged from the coolant distribution device 115 flows into an upper surface of the first heat exchange flow path 161 of the heat exchange filler 160. It spreads widely along the downward movement is discharged to the lower portion of the filler 160 for heat exchange.

In this case, the second heat exchange passage 165 adjacent to the first heat exchange passage 161 passes the cooling water introduced through the cooling water inlet section A by the protrusion guide 166 toward the first heat exchange passage 161. To guide.

In addition, a first air inlet 117 is formed at the lower end of the main body 110.

Here, the first air inlet 117 is formed below the lower filler 150, the first air inlet 117 may be open to the entire lower end of the main body 110.

At this time, the first air inlet 117 prevents the coolant discharged from the lower filler 150 from being discharged to the outside of the main body 110, and smoothly the outside air to the inside of the main body 110. Louvers 113 may be further provided to guide the flow of air to be introduced.

Therefore, the outside air is introduced into the inside of the main body 110 through the first air inlet 117, and then the first heat exchange flow path of the heat exchange filler 160 via the lower filler 150. 161 and the second heat exchange passage 165 are introduced into the lower portion and move upward.

On the other hand, the lower portion of the main body 110 is provided with a lower tank (110a) having an inclination angle and a collecting tank (110b) for collecting the water of the lower tank. As a result, the coolant falling from the lower filler material 150 firstly comes into contact with the lower tank 110a, and the coolant dropped into the lower tank 110a is located in the center of the lower tank 110a. 110b).

In addition, the upper side of the cooling water distribution device 115 is further provided with an eliminator 118 to guide the flow of air and to prevent the cooling water inside the main body 110 is scattered and discharged out through the cylinder 111. Can be.

3 and 4, the filler for heat exchange will be described in more detail.

The first heat exchange passage 161 and the second heat exchange passage 165 of the heat exchange filler 160 are divided into a coolant inflow section A, a coolant flow conversion section B, and a heat exchange section C.

The cooling water inflow section A corresponds to a section in which all the cooling water flowing after the cooling water flows into the first heat exchange passage 161 and the second heat exchange passage 165 flows down the walls of the heat exchange passages.

The coolant flow conversion section (B) is a section in which the coolant flowing along the wall surface of the second heat exchange passage 165 is guided to the first heat exchange passage 161 by the protrusion guide 166.

The heat exchange section C is a section in which the high temperature cooling water flowing through the first heat exchange passage 161 and the air flowing through the second heat exchange passage 165 exchange heat with each other. The air flowing through the second heat exchange passage 165 is heated and in a dry state through indirect heat exchange with cooling water flowing through the first heat exchange passage 161.

As a result, the dry air discharged through the second heat exchange path 165 is mixed with the humidified air discharged through the neighboring first heat exchange path 161 to pass the cylinder through the eliminator 118 inside the main body 110. Through the 111, it is possible to minimize the humidity of the air discharged to the outside to prevent the white smoke phenomenon.

Here, when the height of the sum of the cooling water inflow section (A) and the cooling water flow conversion section (B) in the vertical direction of the heat exchange filler is 1, the height of the heat exchange section (C) is about 2. In addition, the height of the cooling water inlet section (A) is 0.5 or less, and the cooling water flow conversion section (B) preferably has a height of 0.5 or more. This is to allow a sufficient heat exchange to occur by relatively increasing the height of the heat exchange section (C).

Here, although the dry air of the second heat exchange passage 165 heat exchanged in the heat exchange section (C) is moved upward through the coolant inlet section (A) and the coolant flow conversion section (B), the coolant inlet Since the section A and the coolant flow conversion section B are relatively short, they do not significantly affect the humidity of the air.

On the other hand, the protruding guide 166 is a communication hole 167 for communicating the first heat exchange passage 161 and the second heat exchange passage 165 and the internal space of the second heat exchange passage 165. And an inclined portion 168 formed to be inclined upwardly.

The inclined portion 168 flows along the wall surface of the second heat exchange passage 161 and then the second heat exchange passage so that the coolant introduced into the communication hole 167 may be guided to the first heat exchange passage 161. 165 is formed to be inclined upward toward the center.

In addition, the inclined portion 168 may be rounded so that coolant can be stably guided toward the first heat exchange passage 161.

Meanwhile, the heat exchange filler 160 may be formed of a metal material, and the protrusion guide 166 may be formed at predetermined positions on both sides of the heat exchange filler 160 forming the second heat exchange flow path 165. After being cut in the horizontal direction by a predetermined length, the cut portion is formed to have a gentle curved surface by being stretched to protrude upwardly inclined toward the center of the second heat exchange passage 165.

In this case, the protrusion guide 166 is formed having a plurality of rows and a plurality of columns in a portion of the area spaced apart from the top of the filling plate 163 by a predetermined distance.

Further, the protruding guide 166 is upper and lower portions of the cooling water flow conversion section (B) so that the cooling water flowing through the wall of the second heat exchange passage 165 may be guided to the first heat exchange passage 161. It is preferably arranged in a zigzag shape in the horizontal direction.

As a result, the external air moving upward in the first heat exchange passage 161 of the heat exchange filler 160 is in direct contact with the coolant moving downward in the first heat exchange passage 161 of the heat exchange filler 160. Heat exchange occurs with each other.

Accordingly, the high temperature cooling water is deprived of heat and cooled, while the external air is heated. As the heat exchange is performed while directly contacting the cooling water, the heated external air contains steam to achieve a humid state.

In addition, the external air moving upward in the second heat exchange flow path 165 of the heat exchange filler 160 is guided to the first heat exchange flow path 161 by the cooling water introduced by the protrusion guide 166. In the second heat exchange flow path 165 of the filler 160, the external air substantially close to dry air, which contains minute humidity, moves upward.

In this way, the humid air warmed through the first heat exchange passage 161 is substantially dry air discharged upward through the second heat exchange passage 165 in the upper region of the heat exchange filler 160. And a mixed region 130 to be mixed with each other is formed.

In this case, since the humidified air discharged through the first heat exchange passage 161 and the substantially dry air discharged through the second heat exchange passage 165 directly collide with each other, the main body of the mixing zone 130 crosses the main body. The overall humidity balance of the internal air 110 can be achieved quickly and effectively.

In addition, the air having low humidity as a whole can be discharged to the cylinder 111, so that the effective prevention of the white smoke phenomenon is possible.

Referring to FIG. 5, the anti-white smoke countercurrent cooling tower according to the second embodiment of the present invention includes a protrusion guide 166 which is a main part of the anti-smokes countercurrent cooling tower according to the first embodiment of the present invention of FIGS. 2 to 4. As there is a difference, reference is made to FIGS. 2 and 3 together, and the protruding guide 166 ′ having a difference will be mainly described.

In the anti-smoke smoke cooling type tower according to the second embodiment of the present invention, the protrusion guide 166 ′ is provided with an inclined portion 168 ′ and a communication hole 169 ′ so that the coolant can be stably guided to the first heat exchange passage 161. )

In this case, the coolant discharged from the coolant distribution device 115 is introduced into and flows in contact with both surfaces via the coolant inlet section A of the second heat exchange passage 165, and the inclined portion 168 ′ is introduced into the coolant. Preferably, the cooling water introduced from the communication hole 169 ′ is inclined upwardly toward the center of the second heat exchange passage 165 so that the cooling water may be guided toward the first heat exchange passage 161.

In addition, the communication hole 169 ′ may be opened to have a predetermined area on the wall surface of the filling plate 163 forming the second heat exchange passage 165 corresponding to the height of the inclined portion 168 ′. .

Here, the heat exchange filler 160 is provided with a metal material, wherein the protruding guide 166 ′ is formed at a predetermined position on both sides of the heat exchange filler 160 forming the second heat exchange flow path 165. After the lower portion is cut in an open shape in a square by a predetermined length, the cut portion is formed by being tilted to protrude upwardly toward the center of the second heat exchange passage 165. Therefore, the protrusion guide 166 ′ can be easily and stably formed.
