Description

A high-efficiency and energy-saving crossflow cooling tower Technical Field

[0001] This utility model relates to the field of crossflow cooling tower technology, specifically a high-efficiency and energy-saving crossflow cooling tower. Background Technology

[0002] A crossflow cooling tower is a device that cools water. Water flows vertically down from the top of the tower, while air flows horizontally through the water-spraying packing, creating a cooling tower where the airflow and water flow are perpendicular. Based on the quality of the cooling water, they are classified as open-type and closed-type towers. Based on noise level, they are classified as: standard (P), low-noise (D), ultra-low-noise (C), and industrial (G).

[0003] The existing Chinese utility model patent with publication number CN113945102A provides a crossflow cooling tower, including a tower body. A fan is fixedly installed at the left end of the tower body, an impeller is disposed inside the fan, a rotating shaft is welded to the left end of the impeller, a connecting rod is welded to the left end of the rotating shaft, and a steel ball is disposed at the left end of the connecting rod. An air inlet hopper is fixedly installed at the left end of the fan, a filter screen is slidably sleeved inside the air inlet hopper, an inclined block is disposed at the right end of the filter screen, a retaining ring is welded to the inner side of the air inlet hopper, the filter screen is contacted at the left end of the retaining ring, a guide rod is welded to the right end of the filter screen, a stop block is welded to the right end of the guide rod, a first spring is slidably sleeved on the outer side of the guide rod, and a water inlet pipe is fixedly sleeved at the upper end of the tower body. This invention relates to the field of cooling tower technology. This invention has the advantages of preventing dust from entering the cooling tower and facilitating the disassembly and cleaning of the water spray packing.

[0004] In existing crossflow cooling towers, air flows horizontally through the packing layer via side fans, creating a 90° crossflow with the water flow. This prolongs the heat exchange time. Furthermore, the cooling tower uses a spray pump to recycle the used water, increasing the energy consumption of the fans and pumps, resulting in overall increased energy consumption. The water recycling pipes are also prone to clogging, reducing water delivery efficiency.

[0005] Therefore, those skilled in the art have provided a high-efficiency and energy-saving crossflow cooling tower to solve the problems mentioned in the background art. Summary of the Invention

[0006] The purpose of this utility model is to provide a high-efficiency and energy-saving crossflow cooling tower to solve the problem mentioned in the background art that the cooling tower uses a spray pump to recycle the used water, which increases the energy consumption of the fan and water pump, resulting in an increase in overall energy consumption.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency and energy-saving crossflow cooling tower includes:

[0009] The tower body has sliding grooves fixedly installed on both sides of its interior. An installation plate is slidably connected inside each sliding groove, and a packing plate is fixedly connected to the inner side of each installation plate.

[0010] A spray pipe is fixedly installed above the packing plate. A spray head is fixedly installed at the lower end of the spray pipe, and a water supply pipe is fixedly installed at the front of the upper end of the spray pipe.

[0016] As a further improvement of this utility model:

[0017] The maintenance space is fixedly installed at the rear of the tower body, and the upper part of the interior of the maintenance space is fixed.

[0018] A fan is fixedly installed inside the maintenance space, and a fixed plate is fixedly connected inside the maintenance space, with a dehydrator fixedly installed behind the fixed plate.

[0019] As a further embodiment of this utility model: the sliding groove is symmetrically installed on the left and right sides of the tower body with the tower body as the central base; the packing plate is a corrugated plate; the packing plate is installed higher than the water collection tank; the spray pipe is U-shaped and is fixedly connected to the installation port assembly; the spray head is an anti-clogging spray head; the water supply pipe is a T-shaped pipe; and a frequency converter is fixedly installed on the upper end of the water pump.

[0021] As a further embodiment of this utility model: an inspection door is fixedly installed at the rear end of the inspection space, an exhaust port is fixedly opened at the upper end of the inspection space, and the fan is fixedly installed inside the exhaust port.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The packing plates in the tower body are replaced with corrugated PVC packing.

Furthermore, the corrugated plate material has excellent corrosion resistance and can adapt to the corrosive environment of chemicals in the circulating water. Based on the existing spray device, a temperature sensor is added to the water supply pipe of the spray device. The temperature sensor model is NTC104-F-3950 thermistor. The temperature sensor is used to dynamically adjust the spray water volume in real time, thereby reducing water pump energy consumption.

[0024] Multiple sets of installation holes are added to the front end of the tower body, which are connected to the water collection tank through flange-type connecting pipes. Stainless steel is used to ensure corrosion resistance. The water source in the water collection tank in the tower body is transported. An outwardly expanding tapered expansion pipe is installed at the rear end of the connecting pipe. By increasing the flow cross-sectional area, the flow velocity is reduced and turbulent friction loss is reduced. The tapered expansion pipe makes the water flow spread evenly, improving the transportation efficiency from the water collection tank to the external pipeline. A cutting blade is installed in the expansion pipe. When the expansion pipe is blocked by foreign objects, the cutting blade cuts the foreign objects at the expansion pipe, reducing the possibility of blockage inside the pipeline.

It adopts a double-layer corrugated plate structure and the surface is treated with anti-static treatment.

[0048] The working principle of this utility model is as follows:

[0049] When using this invention, the spray head 13 uses a multi-hole flow equalization design to evenly cover the surface of the corrugated packing plate 11 with water, forming a water film or fine water droplets. Air flows horizontally from the air inlet 3 on the side of the tower, flowing in an orthogonal direction to the vertically falling water, forming a transverse cross-flow contact. The water source is delivered to the cooler coil 6 through the hot water inlet 7. The temperature difference between the air and the water leads to direct heat conduction. The high-temperature water transfers heat to the low-temperature air. Some of the water in the cooler coil 6 evaporates into water vapor, absorbing a large amount of latent heat of vaporization, further reducing the water temperature of the cooler coil 6. The cooling water source is discharged from the cold water outlet 8. In order to increase the overall efficiency, the corrugated packing plate 11 is used to increase the gas-liquid contact area. The PVC corrugated plate is used with an alternating peak and valley structure to distribute the air... To reduce airflow resistance, a temperature sensor 15 is added to the water supply pipe 14 in the spray device. The temperature sensor 15 is used to dynamically adjust the spray water volume in real time. The cooled water falls and collects in the bottom water collection tank 5. The water collection tank 5 is connected to the flange of the connecting pipe 17. The water supply pump 18 delivers the water to the water supply pipe 14 through the delivery pipe 16. The connecting pipe 17 is connected to the cone-angle expansion pipe 20. The expansion pipe 20 adopts a cone-angle expansion design. The inner diameter of the inlet end matches the connecting pipe 17, and the cross-sectional area of ​​the outlet end is enlarged to reduce the flow velocity, reduce frictional resistance, and reduce the adhesion of particulate matter. The internal cutting blade 21 is used to cut foreign objects such as fibers and plastic fragments to prevent pipe blockage. The humid and hot air after absorbing heat is discharged through the fan 23 on the maintenance space 22.
