Description

Technical Field

[0001] This utility model relates to the field of waterfall landscapes, and more specifically, it is a heat exchange overflow tower type waterfall landscape. Background Technology

[0002] A cascading waterfall is a landscape feature that uses the difference in terrain elevation to make water flow in a stepped or tiered manner. Through the dynamic changes in the shape of the water flow and the sound and light effects, it not only has high aesthetic value, but also improves the local microenvironment and regulates air humidity. It is a public facility that combines functionality and artistry.

[0003] In the industrial field, heat exchange overflow towers are a common type of heat exchange equipment. Their working principle involves the working fluid overflowing from the top of the tower, forming a liquid film or droplets. Through contact with air, phase change and convective heat transfer are achieved, thereby improving heat exchange efficiency. Currently, further improving the heat exchange efficiency of such equipment is one of the key research focuses in this field. It is worth noting that cascading waterfalls and heat exchange overflow towers share similarities in their fluid motion principles; both achieve flow energy dissipation through the stepped descent of liquid. However, this energy dissipation process is often accompanied by energy loss and waste, failing to fully convert energy into usable energy or enhance the heat exchange effect.

[0004] Therefore, it is necessary to develop a heat exchange overflow tower-type waterfall landscape that uses a heat exchange overflow tower as a pumping device for water, which can heat up or cool down the working fluid, dissipate the energy of high-pressure water, and recover part of the potential energy.

[0007] In the above technical solution, a steel pipe is embedded at the axial position of the heat exchange overflow tower, and a nozzle is installed at the top of the steel pipe and a water inlet is connected at the bottom; the generator is installed on the inner wall of the steel pipe.

[0008] In the above technical solution, the multi-stage drop structure is provided with a first-stage water receiving plate, a second-stage water receiving plate, and a third-stage water receiving plate with progressively larger diameters from top to bottom; the water turbine is installed on the second-stage and third-stage water receiving plates.

[0009] In the above technical solution, the turbine blades are positioned facing the direction of the drop, and the turbine is fixedly supported by the bracket below.

Detailed Implementation

[0022] The following detailed description, in conjunction with the accompanying drawings, illustrates the implementation of this utility model. However, these descriptions do not constitute a limitation of the present utility model and are merely illustrative. Furthermore, the advantages of this utility model will become clearer and easier to understand through this description.

[0023] Referring to the attached drawings, a heat exchange overflow tower-type waterfall landscape is characterized by comprising: a regulating reservoir 100, a heat exchange overflow tower 200 vertically arranged in the middle of the regulating reservoir 100, and a multi-stage waterfall structure 300 installed on the outer wall of the heat exchange overflow tower 200; the diameter of the multi-stage waterfall structure 300 is smaller than that of the regulating reservoir 100. The regulating reservoir 100 is provided with an outlet 110 at its bottom, and an auxiliary water pump 120 is provided at the outlet 110; the heat exchange overflow tower 200 is provided with an inlet 210 at its bottom; multiple water turbines 400 are installed in a circular array on both the regulating reservoir 100 and the multi-stage drop structure 300; the output end of the water turbine 400 is connected to the auxiliary water pump 120 through a generator 410, thereby converting the potential energy of the water into electrical energy to pump the working fluid out of the system.

[0024] A steel pipe 220 is embedded at the axial position of the heat exchange overflow tower 200. A nozzle 230 is installed at the top of the steel pipe 220 and a water inlet 210 is connected to the bottom. The generator 410 is installed on the inner wall of the steel pipe 220.

[0025] The multi-stage drop structure 300 is provided with a first-stage water receiving plate 310, a second-stage water receiving plate 320, and a third-stage water receiving plate 330 with progressively larger diameters from top to bottom; the water turbine 400 is installed on the second-stage water receiving plate 320 and the third-stage water receiving plate 330.

[0026] The turbine blades of the water turbine 400 are positioned facing the direction of the drop, and the water turbine 400 is fixedly supported by the bracket 440 below.

[0027] The secondary water receiving plate 320, the tertiary water receiving plate 330, and the water turbine 400 on the regulating reservoir 100 each correspond to a generator 410; the three generators 410 are connected to the auxiliary water pump 120 in sequence through the grid connection device 420 and the rectifier 430; the generators 410 are used for partial recovery and utilization of potential energy, which improves energy utilization and reduces operating costs.

[0028] The areas of the secondary water receiving plate 320, the tertiary water receiving plate 330, and the regulating reservoir 100 are proportionally increased. The secondary water receiving plate 320 has four water turbines 400 arranged in a circular array at equal intervals, the tertiary water receiving plate 330 has eight water turbines 400 arranged in a circular array at equal intervals, and the regulating reservoir 100 has twelve water turbines 400 arranged in a circular array at equal intervals. The water turbines 400 are designed to more fully agitate the water, increase the contact area with the surrounding air, promote the heat exchange process, and this multi-stage cascading structure 300 also has a certain aesthetic appeal.

[0029] In practical use, the method of using this utility model includes the following steps: Step 1: During operation, the working fluid enters through the inlet 210 at the bottom of the heat exchange overflow tower 200, is transported to the top through the steel pipe 220 embedded in the shaft, and overflows through the nozzle 230; the water falls freely to the first-stage receiving plate 310, and then falls step by step to the second-stage receiving plate 320 and the third-stage receiving plate 330. During this process, the water is disturbed by the blades of the turbine 400, and finally falls to the regulating reservoir 100. The auxiliary water pump 120 pumps the water out from the outlet 110, thus presenting a multi-stage waterfall landscape. Step 2: When the working fluid falls through the multi-stage drop structure 300, it impacts the corresponding turbine 400, driving it to rotate and drive the generator 410 to generate electricity. The electrical energy output by each generator 410 is integrated by the grid connection device 420 at the bottom of the regulating reservoir 100 and converted into a stable current by the rectifier 430, which drives the auxiliary water pump 120 to operate, realizing the conversion and reuse of the working fluid's potential energy into electrical energy.

[0030] In summary, the multi-stage cascading structure 300 extends the cascading distance of the working fluid, significantly increasing its exposure time in the air. The rotation of the turbine 400 breaks the laminar flow of the working fluid, creating a turbulent effect and expanding the contact area between the working fluid and the air. Together, these two processes promote the phase change heat transfer process of the working fluid's evaporation / condensation and improve heat exchange efficiency through forced convection. Furthermore, the turbine converts the gravitational potential energy of the water into kinetic energy, driving the power generation device and subsequently the auxiliary water pump, thus achieving partial recovery and utilization of potential energy.

[0031] All other unspecified parts belong to the prior art.
