Description

Plume abatment induced draft type cooling tower

The present invention relates to a white smoke reduction intake vent cooling tower for cooling condensation of a cooling water or cooling refrigerant, and in particular, it is possible to more easily install and remove a dry heat exchanger at an exhaust port, and to improve white smoke reduction effect. Operation can be controlled efficiently, and in the case of hermetic cooling tower, it is possible to reduce the white smoke, reduce the water and power consumption through wet and dry efficient switching cooling operation control and dry cooling operation. The present invention relates to a white smoke reduction suction ventilating cooling tower that can reduce exclusion and shorten piping and improve the appearance of a cooling tower, and which can reduce costs and simplify maintenance.

Generally air conditioning and refrigeration. Refrigerators or industrial heat exchangers operating in refrigeration equipment, etc., are accompanied by waste heat to be removed, and in order to remove the waste heat, the waste heat must be discharged to the atmosphere using a cooling medium.

The cooling method of cooling tower is divided into air-cooled cooling that performs convective cooling by forced convection of atmospheric air which is lower than the fluid to be cooled, and evaporative cooling that uses the latent heat of evaporation by contact of cooling water and air. Cooling towers are widely used because they provide greater cooling and economical efficiency than any other cooling system.

Conventional evaporative cooling towers have a counter flow type cooling tower in which air flows vertically and cooling water flows vertically, and a cross flow in which air flows horizontally and the cooling water flows vertically. type) It is divided into cooling tower, and the flow method of cooling water includes an open circuit type (e.g., open circuit type) in which evaporative heat exchange is performed by mutual contact while flowing a heat exchanger (filler) in which cooling water and air are opened, and a cooling fluid (cooling water or refrigerant). Although it is generally classified into a closed circuit type in which evaporative heat exchange is performed while contacting the coolant and air on the outer surface of the flowing closed cooling coil, in recent years, an improvement in the heat exchange efficiency of the cooling tower, a decrease in water drop, Development and demand of hybrid circuit type cooling tower employing open heat exchanger and closed heat exchanger for the purpose of water saving That is.

In the ventilation system, a suction vent type is installed at an exhaust port of the cooling tower and passes through a heat exchange part (such as a filler or a heat transfer pipe) to suck and discharge hot air after heat exchange, and a heat exchanger is installed in communication with an air supply port of the cooling tower. It is divided into pressurized ventilation type that discharges high-temperature air that has completed heat exchange by pressurizing and venting external air toward the exhaust.

In addition, cooling towers have the advantages of removing waste heat at the lowest cost and preserving water resources through reuse of water, while the drift and plume, noise and It causes environmental problems such as vibration and providing habitat for Legionella bacteria.

In the environmental problem of such a cooling tower, it will be described with respect to the white smoke that is the subject of the present invention.

White lead is produced by the condensation of moisture contained in saturated wet air after the evaporative heat exchange from the cooling tower is released to the outside of the saturated wet air (RH 100%). Visibility tends to increase.

Citing data from the Korea Meteorological Agency, as shown in Ref. 1. shows the average monthly minimum temperatures, white smoke will always occur in January-March and December, and the frequency of occurrence will be high in April and November. In May-October, it is estimated to occur in the rainy season but at low temperatures.

Therefore, as shown in Reference Photo 1., as long as the cooling tower is operated, if there is a climatic condition in which white smoke is generated, there is only a difference of high visibility or low white smoke.

Since the physical properties of white smoke are pure water vapor, not only do they belong to air pollutants, but they are also harmless to the human body, but due to smoke-like shapes; In the case of a low-pressure climate in the winter, it causes a complaint of visual misunderstanding, misunderstanding of fire, aesthetic damage of the surrounding environment, agonism of Legionella bacteria, aversion of vision, and disturbance of vision. It lowers the synergistic effect of white lead and distributes condensed water not only around the cooling tower but also outside the boundary area.

As the adverse effects on white lead are intensified, in the early 1980s, the cooling tower industry in the United States and Europe began to develop the white lead countermeasure technology in earnest, and the research and development of domestic and foreign industry to reduce white lead has been continued.

Means for reducing ordinary white smoke are

Humidity lower than that of saturated humid air by mixing saturated humid air through wet heat exchanger and low humidity air with reduced humidity by heating through dry heat exchanger (heater) using high temperature cooling water as heating medium. Self-heating white smoke reduction means for evacuating the air to reduce the white smoke;

While passing the entire amount of saturated humid air through the wet heat exchange part through the dry heat exchange part (heating part) that heats either steam, hot water or electricity, the humidity is reduced simultaneously with the heating to exhaust air of humidity lower than the humidity of the saturated wet air. Separate heat source plume reduction means to reduce white smoke,

As shown in Fig. 1, a high temperature cooling water flowing through the dry air passage by forming a dry air passage (air flow only) and a wet air passage (cooling water and air flow) partitioned in the cross flow filler. Low humidity air heated by sensible heat exchange through a filter sheet from the air, and saturated wet air that has passed through the wet blast after the evaporative heat exchange with contact with the cooling water and passes through the wet blast, is mixed with saturated wet air. It can be divided into the self-heating white smoke reduction means of the wet / dry air passage structure to reduce the white smoke by exhausting the air of humidity lower than the humidity of.

Here, the white smoke reduction means having its own heat source dry heat exchange unit does not generate energy costs due to the white smoke reduction operation, but uses the heating heat source medium as cooling water at 37 to 40 ° C., so that it is at a high temperature (60 ° C. or more). The initial cost can be increased by configuring a larger dry heat exchanger than a separate heat source reduction means for heating, and the effect of whitening reduction is significantly lower than that of a separate heat source.

The white smoke reduction means having a separate heat source dry heat exchanger has a higher white smoke reduction effect than any of the white smoke reduction means, but the heating load is large as the total amount of saturated wet air through the wet heat exchanger is reduced, and the heating corresponding to the load is enormous. The adoption is extremely limited by inducing energy costs.

In addition, the white smoke reduction means of the self-heating wet / dry air channel structure has a low initial cost, but a separate dry air path should be configured in the wet heat exchange unit (cross flow filler), so that the heat exchange portion of the heat exchange unit is more than a wet heat exchange cooling tower of the same capacity. Volume can be increased. In this case, the casing of the cooling tower may also increase, causing a cost increase, and the effect of reducing white smoke is also lower than that of the other methods described above.

Next, as will be described with reference to the accompanying drawings for a known technology having a dry heat exchanger is composed of a heat exchanger tube of the fin coil (Fin and tube).

12 is a longitudinal cross-sectional view of a conventional countercurrent cooling tower (Patent Document 1). Hereinafter, it is referred to as "notice technique 1".

As shown in the drawings of the known technology 1 as shown in the drawings and the claims, the known technology 1 provides an exhaust port 212 having an exhaust fan 213 in a fan deck and a tower side part. A lower outdoor air inlet 206 is provided in at least a portion of the 205, and a watering unit 208 for dispersing the water to be cooled is provided in a tower located above the lower external air inlet 206, and Between the lower external airway inlet 206 and the watering unit 208, the outdoor air introduced from the lower external airway inlet 206 is upwardly flowed, and the water to be cooled from the watering unit 208 is downward. A wet heat exchanger 207 for flowing and contacting the outside air with the water to be cooled to exchange heat, and an air passage 211 in the tower located between the water sprayer 208 and the exhaust port 212; An upper outside air inlet 214 is provided in the upper part of the tower, and inside the air passage 211, the upper outside air inlet is provided. A heating unit 218 for exchanging outside air and the heat source medium introduced from 214 in a non-contact state, and introduced from the lower outside air inlet 206 and heated through the wet heat exchange unit 207, In the counterflow type cooling tower, which allows the outside air introduced from the upper outside air inlet 214 and heated through the heating unit 218 to be mixed in the air passage 211,

The upper outer airway inlet 214, the tower overhead (210) provided on the outside of the exhaust port 212, the heating section 218, tower overhead (212) and In the top side to the air passage in the vicinity of that edge tapin 205 crosses 211 and is characterized by a counterflow cooling tower provided with inclined posture.

And, in the identification number of the detailed description, the upper outdoor airway inlet 214, the damper 215 for adjusting the amount of outside air inflow, and opening and closing cover 216 for preventing the inflow of rain water, etc. in rainy weather ) Is posted to enable remote operation.

Namely, "Notice Technology 1", which is provided on the side wall of the tower and is characterized by an upper outside air inlet for controlling an amount of air to be introduced and a heating unit provided in an upright posture inside the upper outside air inlet. Unlike the features of the conventional countercurrent cooling tower cited above,

An upper outer portion airway inlet is provided in the upper tower on the outside of the exhaust port, and wherein the heating is above the top It is a summary of the invention to provide an inclined posture in an air passage near the tower edge where the tower side crosses .

By such a configuration, as shown in the original characters in the drawing, the effect of the smoke prevention is the saturated air air ② changed into evaporative heat exchange while the outside air ① introduced through the lower outdoor air inlet passes through the wet heat exchange unit, and the upper outdoor air inlet. The predetermined low-humidity air ③, which is heated while passing the heating unit ① and the humidity is lowered, is mixed in the air passage and discharges the wet air ④ of lower humidity than the saturated wet air ② to the exhaust port, thereby obtaining a predetermined smoke prevention effect. will be.

However, the known technique 1 comprises a heating part in an air passage (an area with high suction power of the exhaust fan) adjacent to the exhaust fan, so that the heating part passes through the heating part rather than the resistance of the saturated wet air passing through the wet heat exchange part and the eliminator. Due to the low flow resistance, the air may be partially discharged as it is due to the strong suction force of the exhaust fan, which is not completely mixed with saturated wet air. In addition, due to the inadequate means of allowing saturated humid air, which is raised by the suction force of the exhaust fan, to be properly mixed in the air passage (for example, a mixed flow path or an air mixing member, etc.), the exhaust air may be exhausted in an unstable state in which the heated air and the saturated humid air are not properly mixed. In this case, a problem of deterioration of the white smoke reduction efficiency may occur.

In addition, in order to install and inspect / repair heating parts and pipes in the air passage between the top of the tower and the eliminator, a work space for a worker to enter and work is required. At the same time as the height is increased the overall height of the cooling tower can be increased, it is difficult to apply to a conventional conventional cooling tower (cooling tower and conventional installation products manufactured in a general structure) to ensure such height.

In addition, the known technique 1 cannot heat the entire amount of the air discharged to the exhaust port due to its structure, so that there is a limit to the improvement of the white smoke reduction efficiency.

In addition, the control of the damper 215 for adjusting the amount of inlet air to the upper outside air inlet and the control of the opening and closing cover 216 to open and close the upper outside air inlet should be configured according to each function to control the complexity of the control. There is a problem that may cause an increase in the cost, and the corrosion of the heating unit 218 consisting of fin and coils installed in the air passage during the cooling tower is always exposed to saturated wet air.

In addition, the well-known technique 1 is a single unit in the air passage and the saturated wet air passing through the wet heat exchange unit 207 with only a part of the heating air passing through the heating unit 218 heated by a heat source of high temperature cooling water (37-40 ° C.). As a function of reducing white lead by mixing, there is a limit to white lead reduction.

In addition, the known technique 1 is a function of heating only a part of external air that does not heat the entire amount of air passing through the exhaust port 212. The heating air and the wet heat exchanger 207 passing through the heating part 218 in the air passage are provided. When saturated humid air passing through) is generated, a strong and weak rising air flows, unmixed heating air and saturated humid air are discharged to the exhaust port 212 as it is, which may cause an adverse effect on white smoke reduction.

In addition, there is a limitation in shortening the pipe by providing piping for inflow and outflow of the high temperature cooling water, respectively, between the heating units 218 which are spaced apart from each other.

In addition, in each of the heating units 218 spaced apart from each other, flow control valves must be installed to prevent the inflow and outflow of the high temperature coolant.

13 is a schematic longitudinal cross-sectional view of a conventional hybrid cooling tower (Patent Document 2). Hereinafter, it is referred to as "notice technique 2".

As shown in the drawing of the well-known technique 2, the well-known technique 2 has a pair of lower external air | atmosphere entrance 305 comprised in the lower part of both side parts 304 of the cooling tower 301, and a pair of upper part comprised in the upper part. An air mixture formed in the exhaust region facing the upper outside air inlet 313, the dry heat exchanger 311 provided in the pair of upper outside air inlet 313, and the pair of upper outside air inlet 313. A pair of open types provided on both sides of the member 314, the exhaust port 315, the cooling fan part 316 provided in the exhaust port 315, and the cooling tower 301 adjacent to the lower part of the dry heat exchange part 311. A watering unit 309 installed inside the cooling tower 301 in communication with the cooling water distribution duct 308, the pair of open cooling water distribution ducts 308, and an eliminator 310 disposed above the watering unit 309. ), A wet heat exchanger 307 disposed below the sprinkler 309, and a hybrid cold water tank 302 provided below the wet heat exchanger 307. And a tower, characterized.

And, as indicated in the original characters in the drawing, the effect of the smoke prevention is, the saturated air through the change of evaporative heat exchange ① and the outside air inflow into the upper outdoor air inlet ① through the wet heat exchange unit is passed through the wet heat exchange unit. The predetermined low-humidity air ③, which is heated while passing through the dry heat exchange part and the humidity is lowered, is mixed while passing through the air mixing member, and discharges the wet air ④ of lower humidity than the saturated wet air ② to the exhaust port, thereby obtaining a predetermined smoke prevention effect. will be.

Known technology 2 of the above configuration is a large-scale construction site-type cooling tower (concrete structure) installed in large-capacity cooling facilities such as industrial plants, power plants, airports, and the like. It has been supplied to cogeneration plants in Bundang and Pyeongchon new towns, and has been supplied by domestic companies to Incheon International Airport.

However, the known technology 2 is a cooling tower belonging to the same category as reference picture 2. The dry heat exchanger is formed through the side of the casing, the air mixing member, which is a huge structure constituted in the exhaust area, and the tower side. By constituting the cooling water distribution duct, the structure is complicated, the height of the cooling tower is significantly increased, as well as the initial investment is large, the structure is difficult to apply to small and medium (factory manufacturing) cooling tower.

In addition, in the known technique 2, the entire amount of air discharged to the exhaust port cannot be heated due to its structure, so that there is a limit to improving the efficiency of white smoke reduction.

In addition, the well-known technique 2 reduces the white smoke by single mixing in the exhaust region of saturated wet air passing through the wet heat exchange unit with only the heated air passing through the dry heat exchange unit 311 heated by the heat source of the high temperature cooling water (37-40 ° C.). As a function to make whitening, there is a limit to reduction of white smoke.

In addition, the known technique 2 is a function of heating only a part of outside air that does not heat the entire amount of air passing through the exhaust port 315, and heating air passing through the dry heat transfer part 311 in the air passage, and a wet heat exchange part. When the saturated humid air passing through 307 generates a strong-weak imbalanced air stream, the unmixed heating air and saturated humid air are discharged as they are to the exhaust port 315, which may cause side effects in reducing white smoke.

In addition, there is a limitation in the shortening of the pipe by providing the inflow and outflow of the high temperature cooling water between the dry heat bridges 311 which are installed on both sides to be spaced apart from each other.

In addition, each of the dry heat bridges 311 which are installed on both sides to be spaced apart from each other, a flow rate control valve must be essentially installed to prevent the inflow and outflow of the hot coolant.

In addition, the aesthetics of the cooling tower may be damaged by the side exposure of the dry heat transfer part 311 and the cooling water distribution duct 308 and the exposure pipe outside the cooling tower.

In addition, although the amount of outside air introduced into the outside air supply unit is preferably within 20% of the cooling tower rated air flow amount, the outside air amount may be applied to the outside air amount due to the strengthening condition of the white smoke reduction.

In general, the temperature of the outside air where white smoke is generated is significantly lower than the design wet bulb temperature of the cooling tower.
