Description

Induced Draft Cooling Tower with Backflow Prevention

The present invention relates to a pressure-blown cooling tower capable of reducing white smoke, and more particularly, to a pressure-blown cooling tower capable of reducing white smoke, which lowers the temperature of high-temperature cooling water flowing into the pressure-blown cooling tower to suppress an increase in the internal temperature, captures moisture in the exhaust air and supplies it to the inside, and narrows the temperature difference with the outside air to reduce white smoke.

In general, a cooling tower is a device that lowers the temperature of the high-temperature cooling water used for cooling in the indoor unit of a centralized cooling system, i.e., an indoor air conditioner. There are two types: an open type that lowers the temperature of the cooling water through heat transfer that occurs when the cooling water comes into contact with the outside air, and a closed type that lowers the temperature of the cooling water by using the latent heat of vaporization of the evaporated water sprayed on the cooling water in a closed circuit.

Among these, open cooling towers are further divided into counterflow cooling towers, crossflow cooling towers, and non-powered cooling towers. In particular, counterflow cooling towers cool the cooling water by heat transfer that occurs when the relatively low-temperature outside air comes into contact with the relatively high-temperature cooling water by having the outside air that flows in through the open intake at the bottom of the side wall and passes upward through the filler and the cooling water that is sprayed from the injection nozzle located above the filler and falls through the filler by gravity face each other.

A "pressure-driven cooling tower" has been proposed using this prior art technology.

The prior art relates to a cooling tower for cooling cooling water or cooling and condensing refrigerant, and in particular, a cooling tower structure in which a plurality of blower fans are formed in one of a casing (10b) on the transverse side or a partition wall (11a, 11b) facing the casing (10b) on the transverse side, and first and second supply channels are formed to allow supply air to flow separately to each supply channel, thereby facilitating the enlargement of the cooling tower, enabling the continuous expansion of a plurality of cooling towers, reducing the installation area, reducing the supply air blowing turbulence and flow resistance in the supply air channel, preventing the flow imbalance (deflection) of the cooling fluid to improve the heat exchange efficiency, reducing the recirculation of high-temperature exhaust air to suppress the decrease in heat exchange efficiency, collecting a stable amount of cooling water, and performing independent cooling operation for each supply air channel according to the cooling load, and when one supply air channel configuration breaks down or is being maintained, the other one The supply air channel configuration relates to a pressurized air cooling tower that can perform cooling operation, and can maintain cooling operation with the remaining blower fans even when some of the blower fans fail, thereby reducing power consumption and maintenance costs.

These cooling towers produce white smoke when they come into contact with the outside air, as a large number of microscopic bubbles are mixed in the discharged outside air when the temperature is low, such as in winter. This white smoke is usually harmless as condensate, but when the cooling water is contaminated, harmful substances are released into the atmosphere, and a large amount of white smoke obstructs visibility.

Additionally, when a convection cooling tower is installed in an open configuration, there is a problem that cooling water must always be supplied at a certain level because it is discharged together with the air during cooling.

As illustrated in FIGS. 1 to 5, the present invention relates to a pressure-blown cooling tower capable of reducing white smoke, and more specifically, to a pressure-blown cooling tower capable of reducing white smoke, which lowers the temperature of high-temperature cooling water flowing into the pressure-blown cooling tower to suppress an increase in the internal temperature, captures moisture in the exhaust air and supplies it to the inside, and reduces the temperature difference with the outside air to reduce white smoke.

To this end, the present invention comprises a body (10), a water supply unit (20), a blower unit (30), a water collection unit (50), a discharge fan (60), a first chamber (70), a second chamber (71), a branch pipe (72), and a cooling module (80) to lower the temperature of the cooling water introduced into the cooling tower through heat exchange and to reduce the white smoke phenomenon of the discharged air.

The above body (10) is formed with an intake port (11) through which air is drawn in from the lower side and an exhaust port (12) at the upper side.

The above water supply unit (20) receives externally heated cooling water and sprays it from the upper part of the body (10).

The above blower (30) sucks in outside air from the lower part of the body (10) and supplies it to the inside of the body (10) through the suction port (11).

The above filling material (40) exchanges heat with the air supplied from the bottom through the blower (30) and the cooling water falling through the water supply unit (20).

The above-mentioned water collecting part (50) is formed at the lower end of the body (10) and collects the cooling water heat-exchanged in the filler (40) and discharges it to the outside through the drain pipe (51).

The above exhaust fan (60) is coupled to the body (10) so as to be positioned at the exhaust port (12), and discharges outside air introduced through the blower (30) to the exhaust port (12).

The first chamber (70) surrounds the water supply unit (20) from the outside of the body (10), and heat exchange is performed using outside air introduced through the first flow groove (70a) through which air flows.

The second chamber (71) is formed on the upper outer surface of the body (10) and heat exchange is performed using outside air introduced through the second flow groove (71a) through which air flows.

Here, the first and second flow grooves (70a, 71a) are formed at the bottom and top of the first and second chambers (70, 71), respectively, to enable the inflow and exhaust of outside air.

The above branch pipe (72) is inserted into the lower part of the body (10) to suck in a portion of the outside air discharged from the blower (30), and the other side branches off to supply outside air to the first chamber (70) and the second chamber (71).

The cooling module (80) is exposed on one side of the upper portion of the body (10) to the second chamber (71) and on the other side to the inside of the body (10), and captures moisture in the air discharged through the outlet (12) and cools the air.

In this way, cooling water introduced from the outside through the body (10), the water supply unit (20), the blower unit (30), the filler (40), the water collection unit (50) and the discharge fan (60) is cooled and then discharged, thereby automatically performing the cooling in accordance with a typical cooling tower structure.

And the first and second chambers (71) can reduce the white smoke phenomenon by cooling the cooling water introduced through the water supply unit (20) and adjusting the temperature of the discharged air to the outside air by cooling the cooling module (80) and receiving some of the outside air introduced through the blower (30) through the first and second flow grooves (70a, 71a) and then discharging it to the outside.

Each configuration will be explained in detail.

First, the body (10), the water supply unit (20), the blower unit (30), the filler (40), the water collection unit (50) and the discharge fan (60) are formed in a typical structure according to the counterflow type among the open structures of the pressurized blower cooling tower.

At this time, the water supply unit (20) sprays cooling water supplied from the outside into the inside of the body (10), and is located inside the first chamber (70) and is composed of a supply pipe (21), a spray nozzle (22), and an expansion surface (23) so as to lower the temperature of the cooling water through the outside air.

The above supply pipe (21) receives cooling water from the outside, passes through one side of the body (10) and the other side, and both ends are placed inside the first chamber (70).

The above supply pipe (21) is arranged horizontally so as to be exposed on both sides of the first chamber (70), and cooling water is supplied from one side.

At this time, the portion of the supply pipe (21) exposed on both sides of the body (10) is placed inside the first chamber (70).

The above injection nozzles (22) are formed in multiple numbers in the supply pipe (21) so as to be positioned inside the body (10) and spray coolant.

Therefore, the above injection nozzle (22) sprays the cooling water introduced through the supply pipe (21) toward the filler (40) in the form of mist.

The above-mentioned expansion surface (23) is formed in a Java shape on the outer surface of the supply pipe (21) located inside the first chamber (70) to expand the contact area.

The above-mentioned expansion surface (23) is formed in the supply pipe (21) portion located inside the first chamber (70), and is formed in the shape of a Javara or is combined with a Javara-shaped member processed from a material with good thermal conductivity.

Through this, the above water supply unit (20) receives and sprays cooling water heated from the outside.

And the above water supply unit (20) is partially placed inside the first chamber (70) so that the temperature of the cooling water can be lowered and sprayed through heat exchange of the supply pipe (21) with the outside air introduced through the blower unit (30).

At this time, the supply pipe (21) can lower the temperature of the cooling water and the inside of the body (10) through heat exchange in the first chamber (70) portion.

Next, the cooling module (80) is formed at the top of the body (10) and is composed of a heat dissipation fin (81), a cooling plate (82), and a cooling projection (83) to capture moisture contained in the discharged high temperature and humidity air, lower the temperature, reduce the white smoke phenomenon, and reduce the evaporation of the cooling water.

The above heat dissipation fins (81) are arranged in a radial shape with one side bent to contact the inner surface of the second chamber (71) over a large area and the other side protruding into the interior of the body (10).

At this time, the heat dissipation fin (81) has an “ㄴ” or “ㅗ” shape, and one side is in close contact with the inner surface of the second chamber (71) over a large area to facilitate heat transfer, and the other side protrudes into the interior of the body (10).

These heat dissipation fins (81) are arranged radially along the circumference of the body (10) or the exhaust port (12).

The above cooling plates (82) are arranged in a concentric shape at regular intervals inside the body (10) and are connected to a plurality of the above heat dissipation fins (81).

That is, the cooling plates (82) are arranged in a concentric shape inside the body (10) in the form of multiple cylinders having different diameters spaced apart at regular intervals, and are coupled to the other side of the heat dissipation fins (81).

The above cooling protrusions (83) protrude from the inner and outer surfaces of the surface of the cooling plate (82) to have a certain pattern, thereby increasing the contact area with air.

These cooling protrusions (83) are formed in multiple numbers by cutting the cooling plate (82) and bending it on the outer and inner surfaces.

At this time, the cooling projection (83) is bent diagonally toward one side along the circumference of the cooling plate (82) and arranged in a zigzag shape intersecting with each other in the upper and lower directions, so as to be in close contact with the cooling plate (82) adjacent to the outer and inner surfaces, and is arranged to intersect with the cooling projection (83) protruding from the adjacent cooling plate (82).

That is, the cooling projection (83) is bent so as to protrude from the inner and outer surfaces by cutting and bending the cooling plate (82), and forms a passage through which air can be discharged upward by contacting or at least closely contacting the adjacent cooling plate (82).

In this way, the cooling module (80) is arranged on one side in the second chamber (71) to exchange heat with the outside air, and the other side is formed inside the body (10) to form a passage through which air is discharged.

Accordingly, the air discharged from the body (10) passes through the passage of the cooling module (80) and comes into contact with a large area of the cooling projection (83), thereby lowering the temperature of the air and capturing moisture.

At this time, when the temperature of the cooling plate (82) rises, heat is discharged through heat exchange within the second chamber (71) through the heat dissipation fin (81).

And, an exhaust module (90) is further included that cools the air discharged by being coupled to the exhaust port (12) and generates a vortex.

The above-mentioned exhaust module (90) is composed of a first cover (91), a second cover (92), and a vortex plate (93) so that the exhausted air receives the external temperature and lowers the temperature to prevent white smoke phenomenon, and prevents the exhausted air from flowing in through the blower (30).

The first cover (91) is formed with a first expansion plate (91a) having a cone shape in which the lower end is fastened to the discharge port (12) and the upper end gradually widens.

The second cover (92) is placed inside the upper part of the first cover (91), and a second expansion plate (92a) is formed in a cone shape that gradually narrows toward the bottom so as to be level with the first expansion plate (91a).

The above vortex plates (93) are formed in a spiral shape by being joined as a pair to the inner surface of the first cover (91) and the outer surface of the second cover (92).

In this way, the second cover (92) is combined with the upper part of the first cover (91) so that air can be discharged in a cone shape.

At this time, the vortex plate (93) is formed on the first expansion plate (91a) and the second expansion plate (92a) to generate a swirling flow of the discharged air, thereby easily discharging it upwards, thereby preventing a temperature rise around the body (10) and preventing backflow through the blower (30).

And the air discharged through the above discharge port (12) moves along the above vortex plate (93) and comes into contact with the widest possible range, thereby lowering the temperature of the discharged air through heat exchange with the external temperature, thereby preventing the white smoke phenomenon.

And the first cover (91) further includes a collection tube (94) that collects moisture generated on the surface of the vortex plate (93) and supplies it to the body (10), and the second cover (92) further includes a plurality of discharge holes (95) formed at regular intervals along a spiral shape and bent to fit the spiral shape to discharge air.

Here, the above collection tube (94) captures moisture contained in the discharged air in accordance with temperature changes in the first cover (91) and the vortex plate (93), and supplies the captured moisture to the interior of the body (10).

Through this, the above discharge module (90) can capture the cooling water generated from the discharged air and minimize the loss of cooling water.

In addition, the above discharge holes (95) are formed in the second cover (92), and are arranged in multiple numbers with the bending direction adjusted so that air can be discharged by forming them in accordance with the spiral shape of the vortex plate (93).

Through the above-mentioned discharge hole (95), the air pressure introduced into the body (10) can be easily discharged to prevent the internal air from flowing back and the pressure from increasing.

Next, the operating state according to the present invention will be described.

First, the body (10), the water supply unit (20), the blower unit (30), the filler (40), the water collection unit (50), and the exhaust fan (60) operate in accordance with the typical structure of a pressure-injection cooling tower.

Through this, the operation is carried out in accordance with the normal structure so that the coolant introduced from outside can be cooled and then re-supplied.

And, on the outer surface of the body (10), the first chamber (70) and the second chamber (71) are formed, and the branch pipe (72) and the cooling module (80) are formed respectively in accordance with the first and second chambers (70, 71).

Accordingly, the first chamber (70) and the second chamber (71) are supplied with outside air, which is drawn in from the outside through the blower (30), through the branch pipe (72).

When one side of the branch pipe (72) receives outside air from a location adjacent to the blower (30), the other side branches off and supplies outside air to the first chamber (70) and the second chamber (71).

At this time, the first and second chambers (70, 71) receive outside air through the first and second flow grooves (70a, 71a) formed at the bottom, and then discharge the air through the first and second flow grooves (70a, 71a) formed at the top, thereby performing heat exchange inside the chambers.

Therefore, the first chamber (70) can lower the temperature through heat exchange by surrounding the supply pipe (21) exposed to the outside of the body (10).

At this time, the supply pipe (21) is formed so that the widest possible area can come into contact with the outside air within the first chamber (70) through the expansion surface (23).

Accordingly, the outside air introduced into the first chamber (70) through the branch pipe (72) can contact the expansion surface (23) to lower the temperature of the cooling water and the supply pipe (21) whose temperature has increased due to the cooling water.

Through this, the temperature of the cooling water sprayed from the supply pipe (21) is lowered, so that the temperature inside the body (10) can be lowered, thereby suppressing the temperature rise in the surrounding space.

And the second chamber (71) can lower the temperature through heat exchange by surrounding the cooling module (80) exposed to the outside of the body (10).

At this time, the cooling module (80) is placed inside the upper part of the body (10), and an air discharge passage is formed through the cooling plate (82) and the cooling protrusion (83) so that the discharged high temperature and humid air comes into contact with the largest possible area, so that the discharged air lowers its temperature through heat exchange and captures moisture.

And the cooling plate (82) and cooling projection (83), whose temperature is raised by the exhausted air, can transfer heat through the heat dissipation fin (81) and lower the temperature through heat exchange with the outside air introduced into the second chamber (71).

Accordingly, the cooling module (80) can prevent white smoke phenomenon by lowering the temperature of the air discharged from the body (10) to be similar to the external temperature through heat exchange between the outside air supplied to the second chamber (71) and the air discharged from the body (10).

In addition, moisture mixed in the air can be captured through the passage of the cooling module (80) and supplied to the water collection unit (50) through natural fall, thereby minimizing the loss of cooling water.

In addition, since the temperature can be lowered and moisture can be captured through the cooling module (80), there is no need for an emergency prevention plate, eliminator, etc. to capture moisture, so space can be used efficiently.

And the air discharged through the above exhaust port (12) is discharged through the exhaust module (90) so that the temperature is lowered through heat exchange with the outside air and eddies are generated so that the air can easily rise.

That is, the discharge module (90) causes a vortex flow to occur through the vortex plate (93) as the air discharged through the discharge port (12) gradually expands through the passage between the first cover (91) and the second cover (92).

Accordingly, the air discharged through the above discharge port (12) can increase the contact time with the discharge module (90) as much as possible by generating a vortex flow through the above vortex plate (93), thereby lowering the temperature of the discharged air through heat exchange with the outside air.

Through this, the air discharged from the body (10) can reduce the white smoke phenomenon caused by the temperature difference of the outside air.

In addition, a plurality of exhaust holes (95) are formed in the second cover (92) to easily discharge the air in accordance with the pressure discharged from the body (10), thereby forming a vortex in the discharged air.

This prevents the internal pressure of the body (10) from increasing, thereby allowing smooth air flow through the blower (30).

And the air discharged from the body (10) generates a vortex flow through the discharge module (90) and is discharged to the outside, and then easily rises to prevent the surrounding temperature of the body (10) from rising and block the inflow through the blower (30).

And, by forming the collecting tube (94) in the first cover (91), moisture generated in the vortex plate (93) can be collected and supplied to the body (10), thereby suppressing the loss of cooling water.

In this way, the present invention can suppress the temperature rise inside and around the body (10) by lowering the temperature of the cooling water supplied to the body (10) through the outside air and then spraying it.

In addition, the temperature of the high temperature and humid air discharged from the body (10) can be lowered, the moisture can be captured and supplied to the body (10), thereby preventing the loss of cooling water and reducing the white smoke phenomenon.

As described above, the rights of the present invention are not limited to the embodiments described above, but are defined by the scope of the claims, and it is obvious that a person having ordinary skill in the art of the present invention can make various modifications and adaptations within the scope of the rights described in the claims.
