Description

Technical Field

[0001] This invention belongs to the field of cooling towers and relates to a novel water-saving and defogging module, specifically a water-saving and defogging module for air-to-air heat exchange. Background Technology

[0002] The water-saving defogging module is an important component of the defogging cooling tower. It typically features alternating dry-cold and humid-hot channels. The dry-cold channel carries ambient air, while the humid-hot channel allows humid air from inside the tower to flow downwards. Heat transfer occurs as the two air streams pass through the module, causing some water vapor in the humid air to condense and accumulate on the packing plates before falling. This process transforms the humid air from saturated to unsaturated, thus achieving both defogging and cooling. However, in actual production, due to environmental factors and the equipment itself, a significant amount of white fog still remains when the cooled humid air exits the tower, negatively impacting surrounding equipment, buildings, and traffic safety. Furthermore, due to the lack of matching at the bends around the packing sheets in the past, the upper and lower packing sheets were often only directly attached to each other on two flat surfaces, resulting in less adhesive residue and difficulty in bonding the upper and lower sheets. The bonding at the bends around the packing sheets was also unstable and prone to cracking. For example, the existing patent document CN208505080 discloses a cooling tower defogging sheet and defogging module, which includes a square sheet substrate. The substrate is stacked to form the defogging module. Hot and cold air exchange heat through two mutually perpendicular channels formed on the four sides of the defogging module, and the condensate flows back into the cooling tower. However, the unreasonable arrangement of the matching grooves in the substrate makes the connection between the sheets unstable, making the installation of the defogging module difficult. Moreover, the limited surface area due to the increased texture on the substrate sheet results in limited heat exchange capacity.

[0003] Therefore, we propose a new type of packing sheet that has both good defogging and cooling capabilities and a stable fit. Summary of the Invention

[0004] The purpose of this invention is to provide a water-saving and defogging module for gas-to-gas heat exchange.

[0005] The technical solution of this invention:

[0006] A novel water-saving and fog-eliminating module includes multiple stacked packing sheets, no less than three layers, with each pair of layers forming a group, and a hot channel and a cold channel forming a group, with the hot channel and cold channel arranged alternately.

[0007] The packing sheet includes a body and a bent portion;

[0008] The main body is composed of a series of identical packing sheet units. Each packing sheet unit mainly consists of a corrugated surface, reinforcing ribs, and connectors. The corrugated surface is a curved quadrilateral corrugated plate. The reinforcing ribs are formed by a bottom surface, a set of sides with rounded edges, and a set of sides with regularly arranged corrugated grooves. The reinforcing ribs are placed between adjacent corrugated surfaces or between the connecting piece and the corrugated surface at the bend. The corrugated grooves at the edge of the reinforcing rib fit into the corrugated surface. The side of the reinforcing rib connected to the connecting piece has no corrugated groove and fits directly into the connecting piece. The bottom surface has four types of protrusions or grooves, which are either inward or outward. The protrusions and grooves work together to assemble adjacent packing sheets. The combination of inward or outward protrusions or grooves constructs hot and cold channels. Connectors are used for fixed connection at the intersection of four packing sheet units. Connectors are also provided at the condensate channel inlet.

[0009] The bending section consists of bending plates and connecting plates. The bending plates include a first type of bending plate, a second type of bending plate, bosses, and grooves. The first type of bending plate serves as a bending plate for the condensate drainage channel, positioned at the four corners of adjacent packing layers. The first type of bending plate includes a first bending plate, a second bending plate, a third bending plate, and a fourth bending plate. The second type of bending plate is a multi-angle bending plate positioned on the four sides of adjacent packing layers. One set of opposite sides of the second type of bending plate secures the adjacent packing layers, while the other set of opposite sides serves as the inlet and outlet for the hot and cold channels. The second type of bending plate includes a fifth bending plate, a sixth bending plate, a seventh bending plate, and an eighth bending plate. The connecting plates are connected to other components in two ways: the first way is that the connecting plate connects to the first type of... When the bent pieces are in contact, the connecting component between the first type of bent piece, the reinforcing rib of the body, the connector of the body, and the second type of bent piece has four forms of upward or downward bosses or grooves adjacent to the connector to achieve the fit between the two. In the second case, when the connecting piece is not in contact with the first type of bent piece, the connecting component between the reinforcing rib of the body, the connector of the body, and the second type of bent piece also has four forms of upward or downward bosses or grooves adjacent to the connector to achieve the fit between the two. The bosses on the connecting pieces of adjacent packing pieces are arranged opposite each other, so that a hot channel or cold channel is formed between the adjacent packing pieces. The grooves on the connecting pieces of adjacent packing pieces are arranged opposite each other, so that the packing pieces fit together when the next packing piece is installed.

[0010] The cold aisles and hot aisles are arranged alternately, and the cold aisles and hot aisles are independent of each other.

[0011] The new water-saving and defogging module has multiple cold channels and multiple hot channels, with the cold channels and hot channels being equally spaced.

[0012] like Figure 7 and 8As shown, the first type of bent sheet is a regular structure sheet with continuous alternating convex and concave shapes, and has four forms of protrusions or grooves facing inward or outward.

[0013] like Figure 12 As shown, the connector is a parabolic surface with its opening facing upwards.

[0014] like Figure 9 As shown in (a), the boss is formed by three square curved surfaces and one circular curved surface, and it has an inward or outward boss or groove.

[0015] like Figure 9 As shown in (b), the groove is formed by three square curved surfaces and one circular curved surface, and it has an inward or outward boss or groove.

[0016] like Figure 13 , 14 As shown, the connecting piece is a curved trapezoid or curved rectangle formed by three straight lines and one arc.

[0017] The thickness of the packing sheet is 0.4 mm.

[0018] The corrugated surface at each of the four corners of the packing sheet is missing one corner.

[0019] The beneficial effects of the present invention are as follows: the quadrilateral corrugated surface and reinforcing ribs located in the main body can increase the contact area between dry cold air and humid hot air in the main body, thereby enhancing the heat exchange effect; the protrusions located in the reinforcing ribs, the protrusions or depressions located between the fifth to eighth bent pieces and the connectors, and the first to fourth bent pieces can enhance the stability of the connection between the packing sheets.

[0042] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and technical solutions.

[0043] Please see Figures 1 to 18 The present invention provides a novel water-saving and fog-eliminating module, which is composed of multiple packing plates 1, and adjacent packing plates 1 are stacked by rotation and flipping.

[0044] Each packing sheet 1 includes multiple body parts 11 and a bent part 12. The body parts 11 are located inside the packing sheet 1, and the bent part 12 is located around the packing sheet 1. The bent part 12 and part of the body parts 11 are connected by connecting pieces 14 and reinforcing ribs 112, and bosses 15 and connecting pieces 13.

[0045] Furthermore, the reinforcing rib 112 in the body 11, which is connected to the curved quadrilateral corrugated surface 111, has protrusions. The two packing sheets can be fitted together through the protrusions on the reinforcing rib 112, such as... Figure 5 (a) and Figure 6As shown in (a), there are multiple reinforcing ribs 112 in the packing plate 1. Therefore, when the packing plate 1 is installed, each reinforcing rib 112 will form a fit, which can enhance the stability of the defogging module. The humid hot air and dry cold air are respectively on the upper and lower sides of the curved quadrilateral corrugated surface. The corrugated surface can increase the heat exchange area to improve the water saving rate of the defogging module.

[0046] In the bending section 12, the first bending piece 121 to the eighth bending piece 128 are all planar bent plates. The first bending piece 121 to the fourth bending piece 124 each have a protrusion, and these four bending pieces are located at the four corners of the packing sheet 1. Figure 7 As shown in (a), 7(b), 8(a), and 8(b), when packing sheet 1 is installed, the protrusions on the aforementioned bent sheet will create a fit. For example, if 7(a) is flipped over, it can fit with 8(a). When the fit is complete, the four corners are not sealed. Figure 20 Condensate will flow out from the fitting gap 1231 in one corner (taking the third bending piece 123 as an example). The bending piece has many protrusions, which can also enhance the stability of the defogging module.

[0047] In the bending section 12, the first bending piece 121 to the eighth bending piece 128 are all planar bending plates. Among them, the fifth bending piece 125 to the eighth bending piece 128 are located around the packing piece. When the above bending pieces are fitted, they will form a tight fit 1251 on one set of opposite sides of the packing piece 1 (taking the fifth bending piece 125 as an example), and an opening 1261 on the other set of opposite sides (taking the sixth bending piece 126 as an example). When the first packing piece 1 is added, the side where the opening between the second packing piece 1 and the third packing piece 1 is located is in the same direction as the tight fit of the first packing piece 1 and the second packing piece 1. The side where the tight fit between the second packing piece 1 and the third packing piece 1 is located is in the same direction as the opening of the first packing piece 1 and the second packing piece 1. Dry and cold air enters through one opening, and humid and hot air enters through the other opening. After water vapor condenses, it flows out from the gap between the first bending piece to the fourth bending piece.

[0048] To test the performance of the water-saving and defogging module in this invention, an experimental platform for testing the performance of the defogging and water-saving module was built. The module being tested consists of ten packing sheets, including five dry and cold channels and four humid and hot channels. The experimental results are shown in Tables 1 and 2.
