[0001] The present invention relates to a forced draft type counterflow cooling tower,

The present invention relates to a pressurized air blow type countercurrent cooling tower for cooling cooling water or for cooling and condensing a refrigerant. More particularly, the present invention relates to a pressurized air blow type countercurrent cooling tower for separating an air supply channel into a first air supply channel (12) and a second air supply channel (13) Either the casing 10b on the transverse side facing the channel or the partition 11b facing the short side casing 10b and the lower air supply mechanism 19 formed on the lower part of the second air supply channel According to the structure of the cooling tower in which a plurality of blowing fan units are formed in each of the partition walls 11a and the supply air is divided and supplied to each of the partitioned first and second air supply channels 12 and 13, It is possible to easily enlarge and arrange a plurality of cooling towers continuously, to reduce the installation area, to reduce turbulence and flow resistance of the air supply in the air supply channel, and to improve the flow imbalance of the cooling fluid Deflection) to prevent heat exchange efficiency It is possible to reduce the recirculation of the high-temperature exhaust gas to suppress deterioration of heat exchange efficiency, to collect stable cooling water, to independently perform cooling operation for each supply channel according to the cooling load, The configuration of the other air supply channel can be cooled and the cooling operation can be performed at the time of maintenance, and even when some of the blowing fan units fail, the cooling operation is maintained by the other blowing fan units, the consumption power can be saved, To a pressurized air blowing type countercurrent cooling tower capable of reducing costs.

Generally, air conditioning equipment and refrigeration. Refrigerators or industrial heat exchangers operated in refrigerators or the like are accompanied by waste heat to be removed which is transferred from the hot fluid (or refrigerant) flowing in the cooling tower to the cooling air and discharged to the atmosphere.

The heat rejection type of the cooling tower is caused by evaporation of a part of hot fluid in a wet cooling open type heat exchanger in which hot fluid and cooling air are in direct contact with each other and heat exchange occurs Evaporative cooling to cool the hot fluid by latent heat of evaporation,

In a wet cooling closed circuit type heat exchanger in which hot fluid (or refrigerant) is indirectly in contact with cooling air and cooling water, air flowing through the outer surface of the closed heat transfer tube Indirect evaporative cooling for cooling (or condensing) a high temperature fluid (or a refrigerant) flowing through the inside of the heat transfer tube through the contact of the cooling water, heat transfer of the waste heat of the high temperature fluid flowing in the heat transfer tube through the tube wall at a high temperature Dry cooling to cool the hot fluid with sensible heat by transferring it to cooling air with lower temperature than the fluid, hybrid cooling type heat exchanger combining wet cooling heat exchanger and dry cooling heat exchanger And wet-dry hybrid cooling in which the high-temperature fluid is cooled.

And the cooling action can be divided into fluid cooling which lowers the temperature of the liquid (hot fluid, cooling oil, etc.) and fluid condensation which condenses by cooling the gas (refrigerant gas, steam, etc.) .

The cooling air and the cooling fluid flow are divided into a counter flow type in which the cooling air flows upward and a cooling fluid flows downward, an orthogonal flow type in which the cooling air flows horizontally and the cooling fluid flows downward, a cross flow type, and a parallel flow type in which cooling air flows in the same direction as a cooling fluid.

The ventilation system is a natural draft type that uses rising wind force due to difference in the inner and outer air density of natural wind or tower, a mechanical draft type that forced air through a blowing fan, , And an ejector draft type in which air is blown using a cooling fluid injection attractive force of an ejector.

In addition, the air blowing type is an induced draft type in which high temperature cooling air (hereinafter referred to as "exhaust") that has undergone heat exchange in the heat exchanging portion is sucked and discharged to the outside, And a forced draft type in which exhaust gas after heat exchange in the heat exchange section is discharged to the outside.

The discharge method of the exhaust includes a vertical exhaust type in which the fan is vertically upwardly exhausted through a fan cylinder vertical to the fan deck, a horizontal exhaust is horizontally exhausted through a fan cylinder configured horizontally in the side casing (Horizontal exhaust type).

In addition, the blowing fan type can be classified into an axial type fan generally used in a suction ventilation type and a centrifugal type fan used in a pressurized air blowing type.

In addition, the driving method of the blowing fan can be classified into a belt drive type, a gear reducer drive type, and a direct drive type.

 Next, a description will be given of a conventional pressurized air blowing type countercurrent cooling tower which is an object of the present invention.

The construction of the pressurized airflow type countercurrent cooling tower is as shown in the reference figure 1 quoted in the ASHRAE 2000 ASHRAE System and Equipments Handbook, CHAPTER 35. Condensers and CHAPTER 36. Cooling towers, The typical structure of the supply channel, fan outlet, and collecting tank of the countercurrent cooling tower is shown in the reference photograph 1.

The pressurized airflow type countercurrent cooling tower can be easily installed in the indoor space (in this case, feeding and exhausting to the duct), reducing installation area (about 15 ~ 20% reduction) , And iron structure, so it has advantages such as reduction of environmental induction. On the other hand,

(1) Due to the structure of the low-speed exhaust and the exhaust port compared to the suction blowing cooling tower, the recirculation of the high-temperature exhaust increases the heat exchange efficiency.

As shown in References 1 and 1, (2) In order to prevent the cooling water that falls out into the fan discharge port passing through the partition wall from being introduced, a downwardly inclined fan discharge port is extended close to the casing, and the partition and the long- And the air supply channel is narrowed.

③ The supply air supply structure is an air supply structure that flows into the heat exchange part while spreading in the direction of up and down, right and left, and fan outlet, after the discharge air supply is attached to the inner wall of the long side casing facing the fan discharge port. The consumption power of the pressurized blowing type countercurrent cooling tower is increased by about 200 to 300%).

④ Due to the limit of collection capacity due to the structure of the water collecting tank at the lower part between the bulkhead and the casing, instability in the cooling water circulation (such as overflow due to fluctuations of air inflow and circulation cooling water in the cooling water circulation when the water level is insufficient) Waves occur in the water surface of the water tank.

(5) A single-suction cooling tower structure that constitutes a blowing fan section on one side of a casing on the longitudinal side, in which a plurality of cooling towers can be attached to a long-side casing and two or more cooling towers can not be continuously extended. (Cooling tower area + air supply space area) due to the provision of the air supply space at a predetermined interval in the outer direction of the air blowing fan unit in both cases where the two cooling towers are extended and mutually outward.

⑥ It causes side effect (operation frequency of water supply opening and closing due to wave, water loss and damage of the ball tap) to the operation of the water ball tap which is opened and closed according to the water level fluctuation due to the downward discharge air flow. And the like.

Hereinafter, a conventional push-blow type countercurrent cooling tower (hereinafter referred to as "prior art") having a pressurized air blow type countercurrent cooling tower structure as in the present invention will be described with reference to the accompanying drawings.

FIG. As shown in these figures, the pressurized air blow type countercurrent cooling tower 2a of the prior art has a long side casing 10a for forming a heat exchange area 15, a water spraying area 16 and an air supply channel 14, A short side casing 10b and a partition wall 11b; A side feed mechanism 19 provided on the long side casing 10a; An exhaust port 17 formed at the upper end of the casing 10a, 10b; A heat exchanging part (40a) disposed in the heat exchange area (15); A water spray main pipe arranged in a water spray area 16 formed in the upper part of the heat exchange part 40a and spraying the cooling water supplied to the heat exchange part 40a and having a cooling water inlet 51 on one side, A water spraying unit, a water spraying unit 50 composed of a plurality of water spraying nozzles coupled to the water spraying pipe; An eliminator 41 disposed on the water spraying unit 50 to collect water droplets scattered; A fan housing 71b mounted through the opening 10c formed in the partition wall 11b for partitioning the fan room 19b and having a square shaped air supply outlet 74b, a centrifugal blower 71b housed in the fan housing 71b, A fan 72b, and a fan motor 73b for indirectly driving the blowing fan 72b.

And a cooling water outlet 62 provided in one area of the water collecting tank 61 'is disposed at a lower portion between the inner side of the long side casing 10a in the air supply direction and the inclined partition wall 11b A pressurized air blowing type countercurrent cooling tower 2a including a water collecting part 60 'constituted by a pressurized air blowing type countercurrent cooling tower 2a is provided.

A plurality of support beams 19d are provided between the pair of long side casings 10a in order to support the pair of long side casings 10a and to prevent the expansion and contraction deformation of the air supply channels 14. [ Respectively.

As described above, the conventional art has a cooling tower structure having a plurality of blowing fan portions 70c and a single air supply channel 14 on one side of the long-side casing 10a,

It is difficult to increase the size of the cooling tower, and it is impossible to expand and arrange a plurality of cooling towers of two or more units successively,

As shown in Fig. 10, in order to prevent the cooling water which is dripped into the narrow air supply channel 14 and the air supply outlet 74b formed between the inclined partition 11b and the long-side casing 10a, With the structure in which the discharge port 74b is arranged to be inclined downward in the lateral direction of the long side casing 10a, the discharged air is diffused in the direction of the up and down, right and left air supply and discharge ports 74b after being drawn into the inner wall of the long side casing 10a (Unbalance) and power consumption of the cooling air (the consumption power of the pressurized air blowing type countercurrent cooling tower is usually about 200 - 300% < / RTI > increased)
