Description

Technical Field

[0001] This utility model belongs to the technical field of cooling water system equipment, and specifically relates to an assembled cooling device. Background Technology

[0002] Conventional cooling tower equipment has a large overall size, with a height greater than 3500mm and a width greater than 2500mm. Taking the smaller BND-100 counterflow cooling tower as an example, its effective heat exchange tower body dimensions are: L*W*H=2580*2580*3500mm. For cooling towers with external motors, the overall height exceeds 4000mm. These dimensions are not conducive to the overall transportation and hoisting of the equipment. The transportation of various parts and components requires dispatching workers to the project site for construction, assembly, and debugging. For projects located far away, the construction costs, including on-site labor and travel, are high, and it is not conducive to ensuring construction and product quality, easily leading to other quality problems such as cooling tower leakage, component damage, and low efficiency.

[0003] Furthermore, in existing technologies, the temperature difference reduction of conventional civil cooling towers is mostly 5℃, while that of industrial cooling towers is mostly 10-15℃. For cooling towers with larger temperature differences (≥30℃), the technical parameters such as increasing the heat exchange area of ​​the packing, the external dimensions, and the air volume are generally selected to meet the cooling requirements. However, in the frigid regions of Northeast and Northwest my country, where the lowest outdoor temperature in winter is below -30℃, if conventional techniques such as increasing the fan air volume and increasing the heat exchange area of ​​the packing are used, the local heat exchange will be uneven due to the small mass transfer coefficient of hot water in the local heat exchange area and the small amount of water sprayed per unit area. This can lead to local water shortages and freezing and cracking in some areas, resulting in low heat exchange efficiency of the cooling tower or even failure to operate normally, causing unnecessary damage to personnel and equipment and energy waste.

[0004] In view of the practical drawbacks of existing technologies, the technical problem that needs to be solved is: how to design a prefabricated cooling device that is simple in structure, complete in function, highly efficient and energy-saving, and easy to transport and install, and how to achieve high-power operation of small cooling towers through multi-stage linkage of the prefabricated cooling device, so as to solve the above-mentioned technical problems.

The scope of protection of this patent application is determined by the claims.

[0027] Example 1:

[0028] like Figure 1 The embodiment shown discloses a prefabricated cooling device, including a cooling module 1, a water tank 7, a movable crossbeam 2, a cover plate 71, and a lifting ring 76. In the accompanying drawings, the cooling module 1 is located inside the water tank 7, with a design identical to existing structures. From bottom to top, the cooling module 1 includes an air inlet zone 6, heat exchange packing 5, a spray assembly 3, and a fan duct 11. The fan duct 11 is located at the top of the cooling module 1, and a fan 13 and a silencer / sealing valve 12 are installed inside the fan duct 11.

[0029] The upper part of the spray assembly 3 is also connected to a water collector 4, which is a stacked screw structure, and the water collector 4 is used to collect the evaporated liquid from the spray assembly 3.

[0030] The spray assembly 3 includes a water inlet pipe 31 and a heat exchanger 32. A spray pipe 33 is connected to the heat exchanger 32, and several high-pressure nozzles 34 are connected to the lower part of the spray pipe 33.

[0031] The key design feature of this utility model is that: a side support frame 73 is provided inside the water tank 7, and a movable crossbeam 2 is also provided inside the water tank 7, with the movable crossbeam 2 in pressing contact with the side support frame 73; several elongated holes 77 are provided on the top edge of the side support frame 73; such as Figure 4 As shown, the movable crossbeam 2 includes a crossbar 22 and a support column 21. The bottom surface of the crossbar 22 has adjustment holes 24 that engage with elongated holes 77. The top surface of the crossbar 22 has several locking seats 23 for fixing the bottom surface of the cooling module 1. The water tank 7 also has several reinforcing ribs 70 inside, which strengthen the water tank 7 both horizontally and vertically.

[0032] The support column 21 at the bottom of the movable crossbeam 2 contacts the bottom of the water tank 7; the four corners of the bottom of the cooling module 1 are provided with buffer support legs 63, and the bottom surface of the buffer support legs 63 is provided with buffer pads 64. These buffer pads 64 are generally made of rubber. When the buffer support legs 63 contact the movable crossbeam 2 to provide support, the buffer pads 64 can be used for buffering and shock absorption.

[0033] The water tank 7 has a forklift slot 80 at the bottom of its base plate, which allows for forklifts to perform insertion operations. The outer wall of the water tank 7 also has a drain outlet 75 and a water outlet 74, through which spray cooling operations are performed.

[0034] This utility model also has a lifting ring 76 on the movable crossbeam 2, which enables the vertical hoisting of the entire cooling module 1.

[0035] During operation, the cooling module 1 continuously performs vertical spraying. To reduce operating noise, a sound-absorbing pad bracket 61 is provided on the bottom surface of the cooling module 1. The sound-absorbing pad bracket 61 supports the water spraying sound-absorbing pad 62. This device can receive the vertical water spray and absorb the water spraying noise.

[0037] The cooling module 1 uses a parallel connection of 2 to 4 fans, which can effectively reduce the overall height and width of the cooling module unit and control the overall height and width of the equipment within 3000mm, so as to facilitate normal transportation.

[0038] The effective heat dissipation filler cross-sectional dimensions (length * width) of a unit module of the cooling module 1 are: 1000mm*1000mm, 1000mm*1500mm, 1500mm*1500mm, 2000mm*1500mm, 2000mm*2000mm, 2500mm*2000mm, 3000mm*2000mm, 4000mm*2000mm, 5000mm*2000mm, and 6000mm*2000mm.

[0044] When this utility model is in operation, its control logic is as follows: based on the hot water temperature measured by the temperature sensor 86 in the hot water tank 84 and the cold water temperature measured by the temperature sensors 86 in multiple water tanks 7, a simulation comparison calculation is performed to realize the interlock control or adjustment of the start / stop, speed and air volume control of the fan 13.

[0045] The silencer and airtight valve 12 provided in this utility model can be operated in manual or automatic modes, and its start / stop or linear opening angle can be adjusted in conjunction with the fan 13 on the corresponding cooling module 1.

[0046] Implementation Case 3:

[0047] When the room temperature is below -30℃ in winter, according to the simulation calculation, the first set of set-type cooling device opens the silencer valve 12, fan 13, and water pump 85, and the hot water in the hot water tank 84 enters the primary cooling unit 3 through the water inlet pipe 4, and the flow rate and power of the water supply pump 8 are adjusted by the regulating valve 5; the cooled water enters the primary cold water tank 7 and is discharged from the water tank 7 through the water outlet 74.

After the two-stage cooling, the water enters the water tank 7 in the second set of integrated cooling devices and is discharged from the water tank 7 through the outlet 74.

[0051] When the room temperature is below -0℃ in winter, according to the simulation calculation, the silencer valve 12 and fan 13 of the first set of integrated cooling devices, the second set of integrated cooling devices, and the third set of integrated cooling devices are opened. The intermediate cold water in the lower water tank 7 of the second set of integrated cooling devices enters the third set of integrated cooling devices through the water inlet pipe 4. After being cooled by multiple stages, the water enters the water tank 15 of the third set of integrated cooling devices and is discharged from the water tank 7 through the water pump 85 and the water outlet 74.
