Description

Technical Field

[0001] This invention relates to a cylindrical air-cooled water tower with dual functions. Background Technology

[0002] Air-cooled towers and water-cooled towers are commonly used equipment in air separation projects for air precooling. The entire precooling system typically consists of an air-cooled tower, a water-cooled tower, cooling water pumps, chilled water pumps, and a chiller. Both air-cooled and water-cooled towers are cylindrical, and in the same air separation project, their diameters are usually similar, with the air-cooled tower being slightly taller than the water-cooled tower. Currently, in all operational air separation projects, the air-cooled and water-cooled towers are independent towers, and their arrangement takes into account maintenance clearance. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a dual-purpose cylindrical air-cooled tower for both air and water cooling, enabling a single tower to simultaneously meet the functional requirements of both air-cooled and water-cooled towers.

[0004] To achieve the above objectives, the present invention provides a dual-purpose cylindrical air-cooled tower, comprising: a tower body,

[0005] An axially spaced intermediate partition is provided within the tower body. Corresponding to this intermediate partition are upper and lower semi-circular partitions. These partitions divide the tower body into two sealed sub-tower bodies.

[0006] The sub-tower body surrounded by the middle partition, the upper semi-circular partition, and the lower semi-circular partition is a water-cooled tower.

[0007] The sub-tower outside the water-cooled tower inside the tower is an air-cooled tower.

[0008] Furthermore, the tower body is a cylindrical tower body.

[0009] Furthermore, the air-cooled tower is equipped with an air inlet, an air outlet, an upper water inlet, a lower water inlet, a bottom drain outlet, and a top wire mesh demister. The air from the air compressor enters through the air inlet, is cooled by water spray, and then exits through the air outlet.

[0010] Furthermore, the water-cooled tower is equipped with a nitrogen inlet, a nitrogen outlet, a water inlet, a drain outlet, and a top wire mesh demister. The circulating water is cooled in the water-cooled tower using the cooling capacity carried by the nitrogen gas before being reused.

[0011] This invention relates to a dual-purpose cylindrical air-cooled and water-cooled tower, which organically combines an air-cooled tower and a water-cooled tower within a single tower body. While satisfying the independent operation functions of both the air-cooled and water-cooled towers, it significantly reduces the tower's footprint and construction costs, making it suitable for situations with limited construction sites.

Detailed Implementation

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figures 1 to 3 As shown, the dual-purpose cylindrical air-water cooling tower of the present invention includes a tower body (1), a middle partition plate (2), an upper semi-circular partition plate (3), a lower semi-circular partition plate (4), an air inlet (5), an air outlet (6), an upper water inlet (7), a lower water inlet (8), a bottom drain outlet (9), a top wire mesh demister (10), a waste nitrogen inlet (11), a waste nitrogen outlet (12), a water inlet (13), a drain outlet (14), and a top wire mesh demister (15).

[0022] The tower body is cylindrical, and its diameter and height are calculated and determined based on process parameters.

[0023] The internal space of the tower is divided into two parts by a middle partition, an upper semicircular partition, and a lower semicircular partition. One part is used as an air-cooled tower, and the other part is used as a water-cooled tower.

[0024] The air-cooled tower is equipped with an air inlet, an air outlet, an upper water inlet, a lower water inlet, a bottom drain, and a top wire mesh demister. Air from the air compressor enters through the air inlet, is cooled by water spray, and exits through the air outlet.

[0025] The water-cooled tower is equipped with a nitrogen inlet, a nitrogen outlet, a water inlet, a drain outlet, and a top wire mesh demister. The circulating water is cooled in the water-cooled tower using the cooling capacity carried by the nitrogen gas before being reused.

[0026] In summary, this dual-purpose cylindrical air-cooled and water-cooled tower organically combines air-cooled and water-cooled towers, achieving dual-use functionality in one tower. This can significantly reduce the floor space occupied by the air-cooled and water-cooled tower and lower the construction cost.

[0027] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
