Description

Gas cooling system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling tower, a wet purification apparatus, and a device for cooling a high temperature gas discharged from a chimney or the like. More particularly, to a gas cooling apparatus for cooling a high temperature gas to a small amount of cooling heat.

The gas cooling device according to the present invention can be utilized particularly as a device for removing white smoke by cooling the gas containing water vapor discharged from a cooling tower, a wet cleaning device and the like in a cool manner to remove white smoke.

There is a growing demand for cooling towers for cooling large quantities of water used in various plants, factories, and buildings. In the cooling tower, external air is introduced into the cooling tower by using a blower installed at the exhaust port at the upper end, cooling water is sprayed by using a nozzle inside the cooling tower, heat exchange is performed between the water to be cooled and external air, do. At this time, the outside air used for cooling the water to be cooled is discharged from the cooling tower in a state of high temperature and high humidity. When the temperature outside the cooling tower is below the dew point, the moisture contained in the discharged outside air condenses and becomes a droplet of water, scattering light to look like white smoke, which is called white smoke. Such white glaze occurs not only in cooling towers but also in structures that emit high-temperature gases that contain water vapor, such as chimneys and wet scrubbing equipment. There is no legal regulation on white smoke, but it is often mistakenly mistaken for nearby residents to report a fire due to a fire or to discharge pollutants, and complaints often occur.

Conventionally, a method of removing white smoke by cooling the water to be cooled or the cleaning liquid as much as possible by a method of removing white smoke from a cooling tower or a wet cleaning apparatus has been used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. Therefore, the present invention is not limited to the embodiments described below, but may be embodied in other forms. In the drawings, the width, length, thickness, etc. of components may be exaggerated for convenience. Like reference numerals designate like elements throughout the specification.

1 is a schematic view of a cooling tower equipped with an embodiment of a gas cooling apparatus according to the present invention. 1, an embodiment of a gas cooling apparatus according to the present invention includes a gas cooling unit 100 having a gas cooling chamber 110 and a cooling water cooling unit 200 having a cooling water cooling chamber 210 . In this embodiment, the gas cooling chamber 110 is integral with the top of the cooling tower 300.

The gas cooling chamber 110 includes an inlet 111 through which the gas is introduced and an outlet 113 through which the introduced gas is discharged and an inner space 114 through which the introduced gas flows from the inlet 111 toward the outlet 113 (Not shown).

The gas may be a hot gas containing water vapor discharged from a cooling tower, a gas discharged from a wet scrubber, or a hot gas discharged from a chimney. In this embodiment, a gas cooling apparatus coupled to the cooling tower 300 will be described as an example.

The outside air to be supplied to the cooling tower 300 is supplied from below to the outside by the blower 120 installed at the outlet 113 of the gas cooling chamber 110. The outside air supplied to the cooling tower 300 is supplied to the inlet 111 of the gas cooling chamber 110 in a state of high temperature and high humidity by the to-be-cooled water (the cooling water supplied to the cooling tower after heated by the load) supplied to the cooling tower 300 ≪ / RTI > The water to be cooled injected from the water injection nozzle 331 of the cooling tower 300 is cooled by the outside air and then stored in the water to be cooled 336. The stored water to be cooled is supplied to the water-cooling water injection nozzle 331 through the water-cooling water circulation pipe 334.

In the present invention, in the present invention, the cooling water discharged from the cooling tower 300 in the state of containing water vapor and the gas introduced into the gas cooling chamber 110 To remove the white smoke. In this way, the white smoke can be removed with a small amount of cooling heat.

A cooling water reservoir 131 and a cooling water guide plate 133 are installed in the inner space 114 of the gas cooling chamber 110 to store cold cooling water for cooling the gas. The cooling water reservoir 131 is installed in the upper part of the inner space 114. Cooling water storage tank 131 is supplied with cool cooling water through circulation pipe 134. The cooling water overflowing from the cooling water storage tank 131 falls toward the cooling water guide plate 133 while forming a cooling water curtain which obstructs the passage of the gas. A cooling water storage portion 132 is provided under the cooling water guide plate 133.

The cooling water guide plate 133 serves to form a path along which the gas (high-temperature outside air containing steam discharged from the cooling tower) flows together with the side wall 112 of the gas cooling chamber 110. In addition, the cooling water curtain (3) is formed in the cooling water storage tank (131), and the cooled cooling water is guided to the cooling water storage unit (132). And serves to form the cooling water curtain 3 on the flow path of the gas. The gas is not discharged to the outlet 113 without passing through the cooling water curtain 3. Thus, gas and cooling water are brought into complete contact. In the present invention, the frequency of contact between the gas and the cool cooling water can be increased simply by increasing the number of the cooling water guide plates 133.

In this embodiment, the cooling water guide plate 133 extends from the side wall 112 toward the inner space 114. The cooling water guide plate 133 extends in a downwardly inclined state so as to allow the cooling water to flow to the cooling water storage part 132. The remaining space is blocked by the pair of cooling water guide plates 133 so that the gas can flow into the space between the pair of cooling water guide plates 133. [ The cooling water which has struck the cooling water guide plate 133 flows downward along the cooling water guide plate 133 and falls from the end of the cooling water guide plate 133 to the cooling water storage part 132 like waterfall water, And the cooling water curtain 3 is formed between the two portions 132. [

The present embodiment has a cooling water cooling chamber 210 as a cooling device for cooling the cooling water in the cooling water storage part 132 and supplying it to the cooling water storage container 131.

The cooling water cooling chamber 210 has an inlet 211 through which cool outside air for cooling the cooling water flows and an outlet 213 through which the introduced outside air is discharged and an outlet 213 through which the introduced outside air flows from the inlet 211 toward the outlet 213 And a sidewall 212 forming an outer-air flow space 214.

An injection nozzle 237 for injecting cooling water into the outside-air flow space 214 is provided at an upper portion of the outside-air flow space 214 of the cooling-water cooling chamber 210. A cooling water reservoir 236 for storing the cooling water injected from the injection nozzle 237 is disposed below the cooling water cooling chamber 210.

A drain pipe 150 for transferring the cooling water having a slightly increased temperature in contact with the high-temperature gas containing water vapor stored in the cooling water storage unit 132 to the cooling water storage unit 236; a cooling water storage unit 236 To the circulation pipe 134 and the circulation pipe 134 for connecting the cooling water reservoir 236 and the cooling water reservoir 131 so as to supply the cooling water stored in the circulation pipe 134 to the cooling water reservoir 131 of the gas cooling chamber 110 And a circulation pump 135 for circulation.

A connection pipe 234 for connecting the cooling water reservoir 236 and the injection nozzle 237 to supply the cooling water having a slightly increased temperature stored in the cooling water reservoir 236 to the injection nozzle 237, And a pump 245 installed in the pump 234. The cooling water supplied from the injection nozzle 237 is cooled in contact with the cool outside air introduced into the cooling chamber 210.

In the present invention, the cold cooling water cooled by contact with the cold outside air supplied by the blower 220 is supplied to the cooling water reservoir 131 inside the gas cooling chamber 110, Contact with one gas. Cooling water having a slight temperature rise in contact with the gas is recovered in the cooling water cooling chamber 210. That is, the cooling water is not stored in the water to be cooled 336, but is stored in the cooling water restoring unit 236. The cooling water is not mixed with the relatively hot water to be cooled in the water to be cooled 336.

The cold cooling water supplied from the cooling water cooling chamber 210 is not mixed with the water to be cooled in the water to be cooled 336 and cooled again in the cooling water cooling chamber 210 with the temperature slightly raised by heat exchange with the gas.

However, in the present invention, only the high-temperature gas containing the water vapor on the cooling tower 300 is cooled in the cooling water cooling chamber 210 by cooling water chilled by cold outside air. Since only the cooling water having a small amount of cooling heat is cooled by the cooling chamber 210 in contact with the high-temperature gas and the cooling water whose temperature is slightly increased, the white smoke generated in the upper part of the cooling tower 300 can be effectively removed even with a small amount of cooling heat.

Hereinafter, the operation of the gas cooling apparatus according to the present embodiment will be described.

The water to be cooled heated by a load such as a mechanical device is stored in the water to be cooled 336 of the cooling tower 300. The stored water to be cooled is injected from the cooling water injection nozzle 331 and cooled to about 32 ° C by the outside air flowing into the cooling tower 300. In this process, the outside air flowing into the cooling tower 300 is in a state of high temperature and high humidity. When the gas including the water vapor is directly discharged to the outside of the cooling tower 300, water vapor coagulates and water droplets are formed and white smoke is generated.

In the present invention, a high-temperature gas including water vapor discharged from the cooling tower 300 flows into the gas cooling chamber 110, which is integrally coupled to the upper portion of the cooling tower 300. This gas is cooled to less than 18 캜 while passing through the cooling water curtain 3 formed in the internal space 114 of the gas cooling chamber 110 and discharged outside the gas cooling chamber 110. The temperature of the gas is sufficiently lowered in the process of passing through the coolant curtain 3, so that even if this gas is discharged to the outside, white smoke does not occur. The cooling water whose temperature has slightly increased in the process of cooling the gas is first stored in the cooling water storage part 132 and is transferred to the cooling water storage part 236 of the cooling water cooling chamber 210 through the drain pipe 150. The cooling water stored in the cooling water re-storage section 236 is supplied to the injection nozzle 237 along the connection pipe 234 connecting the cooling water storage section 236 and the injection nozzle 237, The cooling water is cooled by the cool outside air flowing into the cooling water cooling chamber 210. Cool cooling water is stored in the cooling water re-storage unit 236 and flows along the circulation pipe 134 connecting the cooling water reservoir 236 and the cooling water reservoir 131 of the gas cooling chamber 110 to the cooling water reservoir 131 .

In the present invention, not only the water to be cooled of the cooling tower 300, but only the high temperature gas including the water vapor introduced into the gas cooling chamber 110 is cooled using the cool cooling water cooled in the cooling water cooling chamber 210, Can be removed.

However, in the present invention, only the high-temperature gas including the water vapor on the cooling tower 300 is cooled using the separate cooling water, , Only the cooling water whose temperature has slightly increased in this process is cooled in the cooling water cooling chamber 210, so that the white smoke can be effectively removed with a small amount of cooling heat.

Figures 2 to 13 show the structure inside the gas cooling chamber of another embodiment according to the present invention.

As shown in Fig. 2, in this embodiment, one cooling water storage unit 132 is provided on the left and right sides, respectively. The configuration of the cooling water guide plate 133 is changed.

The cooling water guide plate 133 includes a first cooling water guide plate 133a and a pair of second cooling water guide plates 133b.

The first cooling water guide plate 133a is inclined so that the cooling water flows to both the left and right cooling water storage parts 132 in the drawing.

The pair of second cooling water guide plates 133b are provided between the first cooling water guide plate 133a and the cooling water storage tank 131 and guide the cooling water dropped while forming the cooling water curtain 3 downwardly from the cooling water storage tank 131 And dropped on the first cooling water guide plate 133a. The pair of second cooling water guide plates 133b extend from the side walls 112 facing each other toward the center of the inner space 114. [ The cooling water flowing along the pair of second cooling water guide plates 133b falls onto the first cooling water guide plate 133a to form the cooling water curtain 3.

The high temperature gas including the water vapor flowing in the downward direction in the drawing passes through the cooling water curtain 3 formed between the first cooling water guide plate 133a and the cooling water storage part 132, the second cooling water guide plate 133b, After passing through the cooling water curtain 3 formed between the first cooling water guide plate 133a and the cooling water curtain 3 formed between the cooling water storage tank 131 and the second cooling water guide plate 133b and then flowing upward in the direction in which the outlet 113 is formed . If necessary, a third cooling water guide plate having the same shape as that of the first cooling water guide plate 133a may be provided on the cooling water guide plate 133b, and cooling water guide plates may be provided thereon.

The first cooling water guide plate 133a and the second cooling water guide plate 133b may be disposed at different positions and only one cooling water storage unit 132 may be provided at the lower center of the inner space 114. [

3, the cooling water curtains 3 are formed by using the cooling water guide plates 133 extending from the side walls 112 opposed to each other with a height difference and the cooling water reservoir 131, The user can also guide the user to the unit 132.

The embodiment shown in FIG. 4 differs from the embodiment shown in FIG. 3 in that the lower edge portion 145 of the cooling water storage tank 131 and the end portion 137 of the cooling water guide plates 133 are rounded downward. The curled end portion 137 serves to change the direction of cooling water falling from the cooling water storage container 131 and the cooling water guide plate 133 by using a Coanda effect. The cooling water dropped from the cooling water storage tank 131 and the cooling water guide plate 133 flows along the curved surface of the curled end portion 137 of the cooling water storage tank 131 and the cooling water guide plate 133 by the Coanda effect. As a result, the cooling water is diverted from the cooling water storage tank 131 and the cooling water guide plate 133 by an oblique line. When the cooling water falls to the diagonal line, the area of the cooling water curtain 3 becomes larger so that the cleaning efficiency is improved.

The cooling water storage unit 132 is provided with a baffle plate 140 for preventing the cooling water from overflowing.

In the embodiment shown in FIG. 5, as in the embodiment shown in FIG. 4, the cooling water dropped from the cooling water storage tank 131 and the cooling water guide plate 133 is diagonally shaded by the Coanda effect. The end 138 of the cooling water guide plate 133 is curled upward so that the cooling water stored in the space surrounded by the cooling water guide plate 133 and the side wall 112 flows to the end portion 138 of the cooling water guide plate 133, So that the cooling water curtain 3 is formed.

6, a cooling water guide bar 139 having a circular cross-section is installed under the end portions of the cooling water storage tank 131 and the cooling water guide plate 133. The cooling water storage tank 131 and the cooling water guide plate 133, The cooling water flowing out of the cooling water guide bar 139 flows along the surface of the cooling water guide bar 139 by the Coanda effect and falls into a diagonal line to form the cooling water curtain 3.

The embodiment shown in FIG. 7 shows a method of constructing the cooling water guide plate 133 to guide the cooling water falling downward from the plurality of cooling water storage tanks 131 when the inner space 114 is wide. 7, in the width direction of the inner space 114, the third cooling water guide plates 133c extending in an inclined downward direction from the side wall 112 and the pair of third cooling water guide plates 133c extending in the opposite directions The fourth cooling water guide plates 133d having the inclined surfaces are appropriately arranged to form a path through which the outside air flows and the cooling water can be guided to the cooling water storage part 132 while forming the cooling water curtain 3 on the path of the outside air have.

The first cooling water guide plate 133e and the pair of second cooling water guide plates 133f may extend horizontally from the side wall 112 as shown in FIG. In addition, the end portion may be inclined.

In the embodiment shown in FIG. 9, the upper surface of the second cooling water guide plate 133g has a conical spiral structure 141 so that the cooling water can perform the conical spiral motion in the second cooling water guide plate 133g. The first cooling water guide plate 133a has the same structure as that of FIG. In this embodiment, the cooling water is rotated by the second cooling water guide plate 133g and is separated from the cooling water, so that the gas including the water vapor and cooling water are more in contact with each other.

In the embodiment shown in FIG. 10, a guide vane 142, which is bent on the second cooling water guide plate 133h, is installed so that the cooling water can rotate in the second cooling water guide plate 133h.
