Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a dry-wet combined water-saving cooling tower. Background Technology

[0002] Cooling towers are common refrigeration equipment, with wet cooling towers being the most prevalent. They utilize cold water spray combined with airflow to achieve heat exchange with fluids. However, conventional wet cooling towers suffer from water loss due to fixed spray nozzles during operation, failing to adequately meet industrial water conservation goals. To address these issues, Chinese utility model patent application number 202322436690.2 discloses a combined dry and wet water-saving cooling tower, which incorporates air cooling and evaporative cooling sections for combined dry and wet cooling. However, in this structure, simultaneous dry and wet cooling, along with air intake at the bottom, affects heat exchange at the top, limiting the effectiveness of the upper air cooling section. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a dry-wet combined water-saving cooling tower that facilitates water conservation while ensuring heat exchange efficiency.

[0004] To achieve the above objectives, this utility model discloses a dry-wet combined water-saving cooling tower, which adopts the following technical solution:

[0005] A combined wet and dry water-saving cooling tower includes a housing, a spray trough at the bottom of the housing, a cooling coil above the spray trough, a spray pipe above the cooling coil, a water collector above the spray pipe, a heat exchange coil above the water collector, a second water collector above the heat exchange coil, and the second water collector is located below the fan structure at the top of the housing. Auxiliary housings are located on both side walls of the housing and are connected to the housing. The heat exchange coil is partially housed within the auxiliary housings. A second fan structure is located above the auxiliary housings. An auxiliary air inlet is located on the bottom surface of the auxiliary housing. Two sets of air inlets are located on the housing, one set positioned below the cooling coil and the other facing the heat exchange coil.

[0006] A further improvement of this utility model of a dry-wet combined water-saving cooling tower is that the heat exchange coil includes a feed end and a discharge end, and the cooling coil includes a second feed end and a second discharge end, with the discharge end also connected to the second feed end.

[0007] A further improvement of this utility model of a dry-wet combined water-saving cooling tower is that an auxiliary air outlet pipe is provided above the auxiliary box, and both the auxiliary air inlet and the auxiliary air outlet pipe are provided with baffles for sealing the space.

[0008] A further improvement of this utility model of a dry-wet combined water-saving cooling tower is that a valve is provided on the connecting pipe between the discharge end and the second inlet end, and the second inlet end is also connected to an external inlet pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention adds an auxiliary box to the side wall of the air-cooled section, achieving air-cooled heat exchange in the same way. On the one hand, it increases the heat exchange area and improves the heat exchange and cooling effect; on the other hand, it increases the adjustment effect according to seasonal temperature, and also helps to improve the whitening effect when used in winter.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 As shown, a combined wet and dry water-saving cooling tower includes a housing 1, a spray trough 2 at the bottom of the housing, a cooling coil 3 above the spray trough, a spray pipe 4 above the cooling coil, a water collector 5 above the spray pipe, a heat exchange coil 6 above the water collector, and a second water collector 7 above the heat exchange coil. The second water collector is located below the fan structure at the top of the housing. This structure is one of the conventional structures of existing combined wet and dry cooling towers. Further, auxiliary housings 8 are provided on both side walls of the housing, connected to the housing. The heat exchange coil is partially placed inside the auxiliary housing. A second fan structure 10 is located above the auxiliary housing. An auxiliary air inlet is located on the bottom surface of the auxiliary housing, and an air inlet is located on the top of the housing. Two sets of air inlets are provided, one set located below the cooling coil and the other set facing the heat exchange coil.

[0015] Specifically, the heat exchange coil includes a feed end 11 and a discharge end 12, and the cooling coil includes a second feed end 13 and a second discharge end 15, with the discharge end also connected to the second feed end. A valve is provided on the connecting pipe between the discharge end and the second feed end, and the second feed end is also connected to an external feed pipe 14. That is, the cooling coil is connected to the heat exchange coil, and the cooling coil is also separately connected to a fluid inlet pipe.

[0016] An auxiliary air outlet duct 9 is installed above the auxiliary housing, and baffles for sealing off the space are installed on both the auxiliary air inlet and the auxiliary air outlet duct. This achieves the sealing of the auxiliary housing.

[0017] The working principle of this utility model is as follows: During dry heat exchange, the upper air inlet is opened, and the fan runs for air-cooled heat exchange. Depending on the temperature at the time, the auxiliary chamber is selected to work to increase the heat exchange effect. During wet heat exchange, the auxiliary chamber works simultaneously to ensure that the temperature is lowered first in the auxiliary chamber, thereby improving the heat exchange efficiency. At this time, since the hot and humid gas generated by the spray heat exchange comes into contact with the main heat exchange coil, the cooling effect is limited. It is necessary to use the auxiliary chamber on the side for air-cooled heat exchange to achieve the cooling effect. On the other hand, when the auxiliary chamber is working, it also reduces the direct discharge of hot and humid gas from one side of the main fan, utilizing the side cold air, which also effectively eliminates white spots.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
