Description

Technical Field

[0001] The invention belongs to the field of cooling towers and relates to a novel water-saving and mist-eliminating module, in particular to a water-saving and mist-eliminating module for air-to-air heat exchange. Background Art

[0002] The water-saving demisting module is an important part of the demisting cooling tower. Generally, the dry cold channel and the wet hot channel are set alternately. The dry cold channel will pass through the ambient air, and the wet hot channel is used to allow the wet hot air in the demisting tower to pass through the demisting tower from top to bottom. When the two air passes through the module, heat transfer will occur, causing part of the water vapor in the wet hot air to condense and gather on the filler sheet, and then fall down, which will change the wet hot air from saturated air to unsaturated air, thereby achieving the purpose of demisting and cooling. However, in actual production, due to the influence of the environment and the demisting tower equipment, a large amount of white fog is still generated when the cooled wet hot air is discharged from the demisting tower, which has an adverse effect on surrounding equipment, buildings and traffic safety. In addition, since the bent parts around the filler sheets in the past were not matched, the four sides of the upper and lower filler sheets were often directly fitted with only two planes, resulting in less retained glue and difficulty in bonding the upper and lower sheets. The bent parts around the filler sheets were not firmly bonded and were prone to cracking. For example, the existing patent document CN208505080 discloses a cooling tower demisting sheet and demisting module, including a sheet substrate with a square structure, which becomes a demisting module after stacking. The two mutually perpendicular channels formed by cold and hot air on the four sides of the demisting module realize heat exchange and allow condensed water to flow back to the interior of the cooling tower. However, the connection between the sheets is not stable enough due to the unreasonable arrangement of the matching grooves of the substrate, which makes the installation of the demisting module difficult, and the heat exchange capacity is limited due to the limited surface area increased by the texture on the substrate sheet.

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

[0004] The purpose of the present invention is to provide a water-saving and mist-eliminating module for air-to-air heat exchange.

[0005] The technical solution of the present invention:

[0006] A novel water-saving mist elimination module comprises a plurality of stacked filler sheets, no less than three layers, with two layers forming a group, a hot channel and a cold channel being formed in a group, and the hot channels and the cold channels are arranged alternately;

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

[0008] The main body is composed of a series of packing sheet units with the same structure, and each packing sheet unit is mainly composed of a corrugated surface, a reinforcing rib and a connecting piece; the corrugated surface is a curved quadrilateral corrugated plate; the reinforcing rib is surrounded by a bottom surface, a group of side surfaces with arc edges, and a group of side surfaces with regularly arranged corrugated grooves; the reinforcing rib is arranged between adjacent corrugated surfaces or between the connecting piece and the corrugated surface of the bending part, and the corrugated groove at the edge of the side surface of the reinforcing rib is in contact with the corrugated surface, and the side surface where the reinforcing rib is connected to the connecting piece has no corrugated groove and is directly in contact with the connecting piece; four forms of inward or outward bosses or grooves are provided at the center of the bottom surface, and the bosses and grooves cooperate to realize the assembly of two adjacent layers of packing sheets, and the hot channel and the cold channel are constructed by the combination of inward or outward bosses or grooves; the connecting piece is used for fixed connection at the intersection of four packing sheet units, and a connecting piece is also provided at the opening of the condensate water channel;

[0009] The bending portion is composed of a bending piece and a connecting piece; the bending piece includes a first type of bending piece, a second type of bending piece, a boss and a groove. The first type of bending piece is used as a bending plate for discharging a condensate water channel, which is arranged at the four corners of two adjacent layers of filler sheets. The first type of bending piece includes a first bending piece, a second bending piece, a third bending piece and a fourth bending piece; the second type of bending piece is a multi-angle bending plate, which is arranged on the four sides of two adjacent layers of filler sheets, one group of second-type bending pieces on opposite sides realizes the fixation of the two adjacent layers of filler sheets, and the other group of second-type bending pieces on opposite sides serve as the inlet and outlet of the hot channel and the cold channel. The second type of bending pieces include a fifth bending piece, a sixth bending piece, a seventh bending piece and an eighth bending piece; there are two situations for connecting the connecting piece with other components: in the first situation, the connecting piece is connected to the first type When the bending sheets are in contact, the connecting components arranged between the first type of bending sheets, the reinforcing ribs of the main body, the connecting parts of the main body and the second type of bending sheets are provided with four forms of upward or downward bosses or grooves adjacent to the connecting parts to achieve the cooperation between the two; in the second case, when the connecting sheet is not in contact with the first type of bending sheets, the connecting components arranged between the reinforcing ribs of the main body, the connecting parts of the main body and the second type of bending sheets are provided with four forms of upward or downward bosses or grooves adjacent to the connecting parts to achieve the cooperation between the two; the bosses on the connecting sheets of two adjacent layers of filler sheets are arranged relatively to form a hot channel or a cold channel between the two adjacent layers of filler sheets; the grooves on the connecting sheets of two adjacent layers of filler sheets are arranged relatively to form a cooperation between the filler sheets when the next filler sheet is installed.

[0010] The cold aisles and hot aisles are staggered and independent of each other.

[0011] The new water-saving mist elimination module has multiple cold channels and multiple hot channels, and the multiple cold channels are equidistantly arranged, and the multiple hot channels are equidistantly arranged.

[0012] like Figure 7 and 8As shown, the first type of bending sheet is a regular structure sheet with continuous convex and concave portions arranged alternately, and is provided with four forms of inward or outward bosses or grooves.

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

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

DETAILED DESCRIPTION

[0042] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0043] See also Figures 1 to 18 The present invention provides a novel water-saving and mist-eliminating module, which is composed of a plurality of filler sheets 1, and adjacent filler sheets 1 are stacked and arranged by rotation and flipping.

[0044] Each packing piece 1 includes a plurality of main bodies 11 and a bending portion 12 . The main body 11 is located inside the packing piece 1 , and the bending portion 12 is located around the packing piece 1 . The bending portion 12 and part of the main body 11 are connected through a connecting piece 14 and a reinforcing rib 112 , a boss 15 and a connecting piece 13 .

[0045] Furthermore, the reinforcing rib 112 in the main body 11 connected to the curved quadrilateral corrugated surface 111 has a protrusion, and the two filler sheets can be matched with the protrusion on the reinforcing rib 112, such as Figure 5 (a) with Figure 6As shown in (a), there are multiple reinforcing ribs 112 in the packing sheet 1, so when the packing sheet 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 the 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] The first bending piece 121 to the eighth bending piece 128 in the bending portion 12 are all flat bending plates, wherein the first bending piece 121 to the fourth bending piece 124 are all provided with protrusions, and the above four bending pieces are located at the four corners of the filler sheet 1, such as Figure 7 As shown in (a), 7(b), 8(a), and 8(b), when the packing sheet 1 is installed, the protrusions on the bent sheet will cooperate. For example, after 7(a) is turned over, it can cooperate with 8(a). When the cooperation is completed, the four corners are not sealed. Fig. 20 The condensed water will flow out from the matching gap 1231 at one corner (taking the third bending piece 123 as an example). The bending piece has more protrusions, which can also enhance the stability of the defogging module.

[0047] The first bending piece 121 to the eighth bending piece 128 in the bending portion 12 are all flat bending plates, among which the fifth 125 to the eighth bending piece 128 are located around the filler piece. When the above-mentioned bending pieces are matched, a tight fit 1251 will be formed on one set of opposite sides of the filler piece 1 (taking the fifth bending piece 125 as an example), and an opening 1261 will be formed on the other set of opposite sides (taking the sixth bending piece 126 as an example). If the first filler piece 1 is added, the side where the opening between the second filler piece 1 and the third filler piece 1 is located is the same as the tight fit direction of the first filler piece 1 and the second filler piece 1, and the side where the tight fit between the second filler piece 1 and the third filler piece 1 is located is the same as the opening direction of the first filler piece 1 and the second filler piece 1. One opening allows dry and cold air to enter, and the other opening allows humid and hot air to enter. After the water vapor is condensed, it flows out from the gap between the first to fourth bending pieces.

[0048] In order to test the performance of the water-saving and mist-eliminating module in the present invention, a mist-eliminating and water-saving module performance test experimental platform was built. The tested module consisted of ten filler sheets, including five dry cold channels and four wet hot channels. The experimental results are shown in Tables 1 and 2.
