Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a wet-dry dual-purpose water spraying filler. Background Art

[0002] At present, the operation mode of the water spraying filler of the open countercurrent cooling tower is relatively single, and it can only operate wetly (the dry cold air directly contacts the hot water for heat exchange and evaporation for cooling). In the cold winter in the northern regions of our country, it cannot perform wet-dry adjustment. The filler layer is prone to icing due to the low temperature, resulting in a decrease in the cooling effect. At the same time, it increases the weight of the tower body, and seriously leads to the collapse of the tower body. In addition, the wet operation cannot effectively utilize the favorable condition of the low environmental temperature in winter to change the operation mode and save water resources. The present invention mainly aims at the switching operation of the open countercurrent cooling tower in cold regions, effectively avoiding the situation of icing of the water spraying filler caused by the low air temperature in winter. At the same time, when the temperature is low, it switches to dry operation, which can effectively control the evaporation of the cooling water, save a large amount of water resources, reduce the frequency of circulating water sewage discharge, and relieve the pressure of sewage treatment.

[0003] The traditional cooling tower filler does not distinguish between wet and dry channels. The hot water enters from the upper part of the filler layer and covers the surface of the filler layer. The dry cold air enters from the lower part of the filler layer and contacts the hot water on the surface of the filler layer for heat transfer and surface evaporation. Through heat transfer and surface evaporation, the dry cold air becomes humid hot air and is discharged from the upper part of the filler layer, taking away the heat at the same time to achieve cooling. When operating in low-temperature weather, due to the low environmental temperature, the cold water cooled in the lower part of the filler layer is easy to freeze after contacting the cold air, blocking some filler channels, which urgently needs to be improved. Content of the Utility Model

[0004] In view of the above problems, a wet-dry dual-purpose water spraying filler is provided at present, aiming to solve the problems existing in the prior art.

[0005] The specific technical solution is as follows:

[0006] A wet-dry dual-purpose water spraying filler includes a filler body. A first channel and a second channel are opened in the filler body. The inlet of the first channel is arranged at the lower left side of the filler body, the outlet of the first channel is arranged at the upper right side of the filler body, the inlet of the second channel is arranged at the lower right side of the filler body, the outlet of the second channel is arranged at the upper left side of the filler body. A thin wall is arranged between the first channel and the second channel to make them not communicate with each other.

[0007] The above-mentioned wet-dry dual-purpose water spraying filler further has the following characteristics. The filler body includes two layers of plate bodies. The two layers of plate bodies are mutually attached to form an integral body. The first channel is opened in the upper layer of the plate body, and the second channel is opened in the lower layer of the plate body.

[0008] Beneficial effects of the above solution: The first channel and the second channel are respectively opened in two layers of the plate body, so that the first channel and the second channel are not connected to each other, and heat exchange can only be carried out through the partition between the two channels.

[0009] The above wet-dry dual-purpose water spray filler also has the following characteristics. The plate body is set in a pentagonal shape. The first opening of the first channel is on the left side of the bottom edge of the whole, the second opening of the first channel extends to the upper right side of the whole, the first opening of the second channel is on the right side of the bottom edge of the whole, and the second opening of the second channel extends to the upper left side of the whole.

[0010] Beneficial effects of the above solution: The first opening of the first channel and the first opening of the second channel are both at the bottom of the plate body. Just set the bottoms of the two wholes opposite to each other to connect and use the two wholes, and no additional connecting device is required.

[0011] The above wet-dry dual-purpose water spray filler also has the following characteristics. The plate body is made of a material with good heat conduction performance.

[0012] Beneficial effects of the above solution: It is convenient for the two media not to directly contact and perform heat exchange through heat conduction. At the same time, the same medium can also enter the two channels to achieve surface evaporation and enhance the heat exchange effect.

[0013] In summary, the beneficial effects of this solution are:

[0014] In the wet-dry dual-purpose water spray filler provided by the present invention, by isolating the two media for heat exchange in different channels, the mutual influence between the two is avoided, so as to avoid ice blockage in the filler layer or reduce surface evaporation to achieve the effect of saving water. When it is necessary to enhance the cooling effect, the two media can flow reversely in the same channel to achieve surface evaporation and enhance the heat exchange and cooling effect. The wet-dry dual-purpose water spray filler provided by the present invention has the function of switchable and alternating operation, achieving the purpose of saving water and solving the problems caused by low temperature environment at the same time.

[0018] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0020] The present utility model will be further described below in conjunction with specific embodiments, but it is not limited to the present utility model.

[0021] Figure 1 It is a front sectional structure schematic diagram of the first layer plate body of the wet-dry dual-purpose water spraying filler of the present utility model. Figure 2 It is a front sectional structure schematic diagram of the second layer plate body of the wet-dry dual-purpose water spraying filler of the present utility model. As Figure 1 Figure 2 shown, the wet-dry dual-purpose water spraying filler provided in this embodiment includes a filler body. A first channel 2 and a second channel 3 are provided in the filler body. The inlet of the first channel 2 is arranged at the lower left side of the filler body, and the outlet of the first channel 2 is arranged at the upper right side of the filler body. The inlet of the second channel 3 is arranged at the lower right side of the filler body, and the outlet of the second channel 3 is arranged at the upper left side of the filler body. A thin wall is provided between the first channel 2 and the second channel 3 to isolate them from each other and prevent them from communicating with each other.

[0022] In the above embodiment, the filler body includes two layer plates 1, and the two layer plates 1 are attached to each other to form a whole. The first channel 2 is provided in the upper layer plate 1, and the second channel 3 is provided in the lower layer plate 1.

[0023] In the above embodiment, the layer plate 1 is set in a pentagonal shape. The first opening of the first channel 2 is at the left side of the bottom of the whole, and the second opening of the first channel 2 extends to the upper right side of the whole. The first opening of the second channel 3 is at the right side of the bottom of the whole, and the second opening of the second channel 3 extends to the upper left side of the whole.

[0024] It should be noted that a clamping portion is provided at the bottom of the whole. When the bottoms of two wholes are tightly abutted against each other, the clamping portion connects them to each other, and the bottom openings of the two wholes communicate with each other.

[0025] It should be noted that the filler is designed in a pentagonal structure, which is beneficial to the splicing of two groups of fillers to form a cross double-channel operation structure, facilitating the separation of the inlet into two non-identical channels for operation. The pentagonal structure is beneficial to the combined installation to increase the surface area ratio of the filler structure and improve the heat exchange area. Compared with the triangular structure, the pentagonal structure can separate the channels for operation or run in the same direction.

[0026] In the above embodiment, the plate body 1 is made of a material with good heat conduction performance.

[0027] It should be noted that during use, the bottoms of the two units are abutted against each other, so that the first openings of the first channels 2 in the two units are interconnected, and the first openings of the second channels 3 in the two units are interconnected, and then they can be used in combination.

[0028] Working principle: When dry operation is required, after the bottoms of the two units are abutted against each other and combined, the first openings of the first channels 2 in the two units are interconnected, and the first openings of the second channels 3 in the two units are interconnected. At this time, hot water is introduced from the upper right opening, and cold air is introduced from the lower left opening. The cold air and the hot water exchange heat when passing through the first channel 2 and the second channel 3 respectively, and the hot air is discharged from the upper left opening, and the cold water is discharged from the lower right opening. When wet operation is required, cold air is introduced from the lower left opening and the lower right opening, and hot water is introduced from the upper right opening and the upper left opening. The cold air and the hot air contact and exchange heat in the first channel 2 and the second channel 3 until the cold water is discharged from the lower left opening and the lower right opening, and the humid hot air is discharged from the upper left opening and the upper right opening.

[0029] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the content of the specification of the present invention should be included in the protection scope of the present invention.
