Description

SOLAR UPDRAFT POWERPLANT HAVING AIR PURIFICATION FUNCTION}

The present invention relates to a solar heat rising air power plant, and more particularly, to a solar heat rising air power plant having an air purification function.

A solar updraft tower is a facility for generating electric power from relatively low temperature solar heat. The solar upward airflow tower may be referred to as a “solar upward airflow power plant”. Sunlight heats air in collectors, such as very large greenhouses, and the heated air can form an upward stream in the chimney. This flow of air can drive wind turbines to generate power.

The air purifying tower may inhale air from outside and purify it to discharge it. Air purification towers can be a solution to air pollution in that they process large amounts of contaminated air.

Solar rising air towers and air purification towers may require high construction costs. The solar riser tower can be similar to an air purifier tower in that it applies air flow. The solar rising airflow tower with air purification function can be considered as a solution to the high construction cost problem.

Referring to FIG. 1, a solar updraft power plant 100 according to an embodiment of the present invention may be installed on the ground 50. The solar rising airflow power plant 100 may be referred to as a “power plant”. The solar rising airflow power plant 100 may be referred to as a “solar rising airflow power plant having an air purifying function”.

The solar rising airflow power plant 100 may include a chimney 200 and a roof 250. The place where the solar thermal airflow power plant 100 is installed may be an area where the annual precipitation is small and the amount of solar radiation is high due to drying.

The roof 250 may be installed on the ground 50. A portion of the roof 250 may communicate with the outside. For example, at least a portion of the peripheral edge of the roof 250 may be spaced apart from the ground 50. The roof 250 and the ground 50 are separated from each other, and air outside the roof 250 may flow under the roof 250. The roof 250 may form an uphill slope in a direction from the outer periphery toward the center.

A space may be formed between the roof 250 and the ground 50. Air located in the space between the roof 250 and the ground 50 may be referred to as “internal air”. Air located outside the roof 250 may be referred to as “outside air”.

At least a portion of the sunlight incident on the roof 250 from the top of the roof 250 may provide thermal energy to the roof 250. Most of the sunlight incident on the roof 250 from the top of the roof 250 may pass through the roof 250. The sunlight transmitted through the roof 250 may provide thermal energy to the internal air. The sunlight transmitted through the roof 250 may directly transfer heat energy to the internal air or heat energy to the ground 50. By raising the temperature of the ground 50 provided with thermal energy, radiant heat can be provided to the internal air. The temperature of the internal air can be increased by radiant heat from the ground (50). Radiant heat from the ground 50 can contribute to a high specific gravity of the temperature of the internal air.

When the temperature of the internal air rises, the density of the internal air may decrease. When the density of the internal air is lowered, the internal air may have a property to increase. Therefore, the inside air may be discharged to the outside through the column 210 located in the center of the roof 250 by moving the space between the roof 250 and the ground 50.

The chimney 200 may include a pillar 210 and a pedestal 220. The pedestal 220 may be located between the ground 50 and the pillar 210. The chimney 200 may include a pillar 210 and a pedestal 220, and a base 230. have. The base 230 may be installed on the ground 50. The pedestal 220 may be installed on the top of the base 230. The pillar 210 may be installed on the top of the pedestal 220.

The internal air passes through the wind tunnel 310 composed of one or a plurality depending on the size of the chimney 200. The flow of internal air is horizontal between the roof 250 and the ground 50, and may be converted to a vertical direction after entering the wind tunnel 310. The wind tunnel 310 may be designed to minimize energy loss due to turbulence that may be generated by changing the direction of movement of internal air. The inside of the wind tunnel 310 may be designed to form a venturi shape so that the speed of the inside air reaches the maximum in the nozzle neck portion. In the case of wind power generating electricity by turning the turbine using the flow of air, the power that can be obtained is proportional to the third power of the air velocity, so it is important to maximize the air velocity at the location where the turbine is to be installed. The tunnel 310 can be designed for this purpose.

The suction port 240 may be formed on the base 230. A plurality of suction ports 240 may be formed. Internal air may be introduced into the intake port 240. The inside air introduced into the intake 240 may be discharged to the outside through the pedestal 220 and the pillar 210. In the process in which the internal air moves from the intake 240 through the pedestal 220 toward the pillar 210, power generation using the flow of the internal air may be performed.

The base 230 may protrude with the suction port 240 interposed therebetween. The protruding shape of the base 230 may guide internal air to the intake port 240. That is, the protruding shape of the base 230 with the inlet 240 interposed therebetween can increase the pressure of the internal air flowing into the inlet 240. Therefore, the protruding shape of the base 230 can increase the efficiency of power generation using the flow of internal air.

2, a cross-sectional perspective view of the chimney 200 can be observed. The tunnel 300 may be formed in the chimney 200. The tunnel 300 may be in communication with the suction port 240.

The tunnel 300 may include a wind tunnel 310. The wind tunnel 310 may be formed to extend from the suction port 240. The wind tunnel 310 may include a horizontal portion 311, a bending portion 313, and a vertical portion 315. The internal air flowing into the intake port 240 may sequentially pass through the horizontal portion 311, the bending portion 313, and the vertical portion 315.

The horizontal portion 311 may be formed to extend from the suction port 240 toward the center of the base 230. The horizontal portion 311 may be formed on the base 230. The horizontal portion 311 may be substantially parallel to a horizontal plane.

The bending portion 313 may extend from the horizontal portion 311 but bend toward the upper portion. The bending portion 313 may communicate with the horizontal portion 311. The direction of movement of the internal air may be switched in the bending portion 313. The internal air moving in the horizontal direction from the horizontal portion 311 may reach the bending portion 313 and move in the vertical direction. The bending portion 313 may convert the flow of internal air from horizontal to vertical.

The vertical portion 315 may extend from the bending portion 313 toward the top. The vertical portion 315 may communicate with the bending portion 313. The vertical portion 315 may communicate with the interior of the pillar 210.

The tunnel 300 may include an upper tunnel 340. The upper tunnel 340 may be formed on the pillar 210. The upper tunnel 340 may be understood as a hollow portion formed in the pillar 210. The upper tunnel 340 may communicate with the outside at an upper end of the pillar 210.

The air purification assembly 400 may be installed on the ground 50. The air purification assembly 400 may be located under the roof 250. The air purification assembly 400 may be located outside the chimney 200. For example, the air purification assembly 400 may have a shape surrounding the outer periphery of the chimney 200. For example, the air purification assembly 400 may have a shape surrounding the outside of the base 230 (see FIG. 1). In other words, the internal air moving from the outer periphery of the roof 250 to the center may reach the air purification assembly 400 before reaching the base 230 (see FIG. 1). Therefore, the air purification assembly 400 may have a structure capable of removing dust from the internal air while the increased speed is not decelerated while the internal air comes to the front of the chimney 200.

The internal air may form a wind by proceeding from the outer periphery of the solar thermal airflow power plant 100 toward the center. The wind traveling from the outer periphery of the solar thermal airflow power plant 100 toward the center may reach the air purification assembly 400.

The other side of the first plate 411 may be adjacent to A2. One side of the first plate 411 can be said to be the inner side of the first plate 411. The other side of the first plate 411 can be said to be the outside of the first plate 411.

The second plate 420 may be formed to extend from one side of the second plate 420 to the other side. One side of the second plate 420 may be adjacent to A1. The other side of the second plate 420 may be adjacent to A2. One side of the second plate 420 may be referred to as an inner side of the second plate 420. The other side of the second plate 420 may be said to be the outside of the second plate 420.

One side of the second plate 420 may be closer to A1 by the first gap G1 than one side of the first plate 411. That is, one side of the second plate 420 may be adjacent to the chimney 200 (see FIG. 3) by a first gap G1 than one side of the first plate 411. The inner surface of the air purification assembly 400 may be inclined away from the hollow portion 405 (see FIG. 4) toward the upper portion. For example, the inner surface of the air purification assembly 400 may include the shape of a truncated cone. Alternatively, the hollow portion 405 (see FIG. 4) may include a conical shape. For example, the inner surface of the air purification assembly 400 may include the shape of an inverted truncated cone. Alternatively, the hollow portion 405 (see FIG. 4) may include an inverted truncated cone shape.

The other side of the first plate 411 may be closer to A2 by the second gap G2 than the other side of the second plate 420.

For example, the filter beam 430 may be inclined to adjoin the outer periphery of the air purification assembly 400 as it goes from bottom to top. That is, the filter beam 430 may be inclined to adjoin the center (A1 side) of the air purification assembly 400 as it goes from top to bottom.

The filter beam 430 may form an angle with a horizontal plane. For example, the filter beam 430 may form an angle with a horizontal plane so as to go closer to the outer periphery of the roof 250 (see FIG. 3). The angles formed by the plurality of filter beams 430 and the horizontal plane may have a profile. For example, the angle formed by the plurality of filter beams 430 and the horizontal plane may be smaller toward the outside of the air purification assembly 400. The angles formed by the plurality of filter beams 430 and the horizontal plane may depend on the first length L1, the second length L2, the first gap G1, and the first height H1.

3 and 8, air can move from A2 to A1. The direction from A2 to A1 may be a direction toward the chimney 200 (see FIG. 3) from the outer periphery of the solar thermal airflow power plant 100 (see FIG. 3). The force received by water positioned above the filter beam 430 may be a vector sum of the first force and the second force. The first force may be gravity in a direction from the first plate 411 to the second plate 420. The second force may be a force due to wind (air movement) in the direction from A2 to A1.

The direction of the force received by the water located at the top of the filter beam 430 may be the sum of the direction from the outside to the inside of the air purification assembly 400 and the direction below. That is, the direction of the force received by the water located above the filter beam 430 may form an angle with respect to the horizontal plane. The angle formed by the filter beam 430 shown in FIG. 7 and the “direction of the force received by water located at the top of the filter beam 430” is the filter beam 430 shown in FIG. 8 and “ The direction of the force received by the water located above the filter beam 430 may be greater than the angle formed.

The force acting on the water located at the top of the filter beam 430 is relative to the water located at the top of the filter beam 430 to the second plate 420 along the filter beam 430 Can be easily moved. Therefore, due to the inclined posture of the filter beam 430, water located in the filter beam 430 may be relatively less separated from the filter beam 430. That is, the inclined posture of the filter beam 430 may improve the performance of the air purification assembly 400.

The third signal S3 may include information regarding air humidity.

The solar rising airflow power plant 100 may include a control unit 600. The control unit 600 may be electrically connected to the sensor unit 500 and the circulation module 450. The controller 600 may be implemented by including at least one of a computer, a server, a workstation, a logic circuit, and a circuit board.

The control unit 600 may receive the input signals S1, S2, and S3 from the sensor unit 500.
