Description

Technical Field

[0001] This invention relates to the field of waste heat recovery power generation technology, specifically to a comprehensive water treatment device for shape memory alloy waste heat power generation. Background Technology

[0002] Shape memory alloys (SMAs) are materials composed of two or more metallic elements that exhibit shape memory effects through thermoelasticity and martensitic phase transformation and its inverse. They undergo plastic deformation at low temperatures, and when heated to a specific temperature, the alloy generates recovery stress that forces it to return to its initial shape. Ni-Ti alloys are the earliest developed and most comprehensively studied alloys in this field, possessing advantages such as excellent shape memory properties, strong fatigue resistance, and superior biocompatibility. As a special new type of functional material, shape memory alloys integrate sensing and actuation, and due to their unique functions, they can be widely used to manufacture high-performance, highly automated components.

[0003] Shape memory alloys can be driven by various methods, including temperature, stress, and electric field, with temperature-driven research being the most common. Shape memory alloys undergo plastic deformation at low temperatures, and when heated to a specific temperature, the alloy generates recovery stress that forces it to return to its initial shape. This driving method is simple and easy to implement; deformation can be controlled simply by adjusting the ambient temperature. Meanwhile, the low-temperature waste heat in industrial wastewater discharged from the steel industry has enormous potential for recovery. However, traditional waste heat recovery devices have shortcomings in energy conversion efficiency, structural complexity, automation level, intermittent waste heat utilization, thermal pollution, scalability, and maintenance costs. Summary of the Invention

[0004] To address the shortcomings of traditional waste heat recovery devices mentioned above in terms of energy conversion efficiency, structural complexity, automation level, intermittent waste heat utilization, thermal pollution, scalability, and maintenance costs, this invention proposes a comprehensive water treatment device for waste heat power generation using shape memory alloys. This invention utilizes waste heat from wastewater to drive the deformation of a shape memory alloy, thereby powering a generator. By leveraging the shape memory effect and temperature-sensitive properties of the alloy, waste heat from high-temperature industrial wastewater is utilized to convert thermal energy into kinetic energy, which then drives a motor to generate electricity.

[0005] This invention proposes a comprehensive water treatment device for waste heat power generation using shape memory alloys. Specifically, it includes two discs and a water tank. The two discs are set inside the water tank by a support, and the lower end of the discs is submerged in water. The two discs are arranged opposite each other in a V-shape in the horizontal direction. The two discs are connected by several shape memory alloy springs, and the connection position is located at the edge of the discs. One end of the water tank is provided with a water inlet, and the other end is provided with a water outlet.

[0006] Furthermore, the immersion area of ​​the disk is less than half the size of the disk.

[0007] Furthermore, a filter cartridge is detachably installed inside the water tank, and the filter cartridge is connected to the water inlet.

[0008] Furthermore, a solar panel is installed at an angle on the upper part of the water tank.

[0009] Furthermore, valves are installed at the inlet and outlet.

[0010] Furthermore, the shape memory alloy spring is made of Ni-Ti alloy.

[0011] The beneficial effects of the integrated water treatment device for shape memory alloy waste heat power generation described in this invention are as follows:

[0012] (1) The integrated water treatment device for waste heat power generation of shape memory alloy described in this invention effectively converts the heat energy in industrial wastewater into mechanical energy through the shape memory alloy spring and disc, and then into electrical energy. It makes full use of the waste heat resources in the wastewater, reduces energy waste, has a simple structure, is easy to manufacture and maintain, and reduces the implementation cost.

[0013] (2) The integrated water treatment device for waste heat power generation of shape memory alloy described in this invention can automatically circulate and operate without external power input by utilizing the temperature-sensitive characteristics of shape memory alloy (high temperature shrinkage, low temperature elongation), thus realizing the automation of waste heat utilization.

[0014] (3) The integrated water treatment device for waste heat power generation of shape memory alloy described in this invention has strong overall scalability and adaptability. If the wastewater temperature is high and the waste heat is not fully utilized, multiple treatment devices can be connected in series to further recover the waste heat and improve energy utilization efficiency. The temperature-sensitive characteristics of different shape memory alloys enable them to adapt to wastewater of different temperatures. The device can adjust the tilt angle of the disc according to the actual wastewater temperature to optimize energy conversion efficiency. It can achieve intermittent operation by linking the water level sensor with the quick water exchange valve to complete the batch replacement of wastewater, adapt to the intermittent discharge of industrial wastewater and the continuous operation requirements of industrial production lines, and improve the flexibility and applicability of the device.

[0015] (4) The integrated water treatment device for waste heat power generation using shape memory alloy described in this invention directly drives the disk to rotate by the contraction and elongation of the shape memory alloy, reducing energy loss during the conversion process and improving energy conversion efficiency. The device integrates wastewater treatment and waste heat power generation by recovering heat energy from wastewater, reducing dependence on traditional energy sources, achieving combined heat and power generation, lowering carbon emissions, saving energy and reducing emissions, and being green and environmentally friendly, meeting the requirements of environmental protection and sustainable development.

[0025] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Specific implementation method one: See Figures 1-3 This embodiment is described in detail. The integrated water treatment device for shape memory alloy waste heat power generation described in this embodiment specifically includes two discs and a water tank 5. Disc 1 6 is mounted inside the water tank 5 via support 1 8, and disc 2 7 is mounted inside the water tank 5 via support 2 9. The lower ends of discs 1 6 and 2 7 are submerged in water, with the submerged area being less than half of the disc. Discs 1 6 and 2 7 are arranged in a V-shape facing each other in the horizontal direction, at a certain angle to each other; that is, discs 1 6 and 2 7 are closer together on one side and further apart on the other side in the horizontal direction. Figure 1 and Figure 2 As shown; disk 1 6 and disk 2 7 are connected by several memory alloy springs, with the connection points located at the edges of the disks; hook devices are provided at four positions on the disks (top, bottom, left, and right), and the memory alloy springs are connected to the hook devices; the memory alloy springs include memory alloy spring 1, memory alloy spring 2, memory alloy spring 3, and memory alloy spring 4, which are respectively located at one-quarter positions of the circumference edges of disk 1 6 and disk 2 7; water tank 5 has an inlet 10 at one end and an outlet 11 at the other end.

[0027] The water tank 5 is equipped with a detachable filter cylinder 12, which is connected to the water inlet 10. Adsorbent material can be placed in the filter cylinder 12 for water purification. A solar panel 13 is inclinedly installed at the top of the water tank 5, which makes the water tank 5 semi-enclosed to reduce waste heat loss.

[0028] Valves are installed at the inlet 10 and outlet 11 to control the intermittent passage of high-temperature wastewater.

[0029] The shape memory alloy spring is made of a nickel-titanium shape memory alloy with temperature-sensitive properties. It can stretch when cooled at room temperature and shrink back to its original length when heated.

[0030] The specific working process of the integrated water treatment device for shape memory alloy waste heat power generation described in this invention is as follows:

[0031] Shape memory alloys are stretched into spring-like spiral shapes under low-temperature conditions. Four alloys of equal length are selected, and the two ends of the springs are fixed to the four corresponding positions (top, bottom, left, and right) of discs 6 and 7. Since discs 6 and 7 are close to each other on one side and far apart on the other, one side of the spring is in a compressed state, while the other side is in a stretched state. Discs 6 and 7 are fixed to rigid rod support devices at the bottom of water tank 5, and the supports are installed in appropriate positions inside the water tank to allow the shape memory alloys to stretch and shorten to the maximum extent.

[0032] High-temperature industrial wastewater enters tank 5 through inlet 10. The wastewater level rises to cover shape memory alloy spring 4. When the water level rises below shape memory alloy springs 2 and 3, the valve at inlet 10 closes, stopping the flow of wastewater (the outlet valve remains closed during this period). Shape memory alloy spring 1 is located in the air above, while shape memory alloy springs 2 and 3 are located above the liquid surface. When shape memory alloy spring 4 is heated to its phase change temperature, it recovers its original shape and contracts, thereby driving the disk to rotate. It moves from the lower end of the disk towards the side with the smaller distance between disks 1 and 2. Shape memory alloy springs 1, 2, and 3 cool upon contact with air, lose their ability to recover their original shape, and elongate. They move sequentially from the side with the smaller distance between disks 1 and 2 to the side with the larger distance, driving the disk to rotate. The shape memory alloy spring 4 rotates to the position of shape memory alloy spring 2, and the shape memory alloy spring 1 rotates to the position of shape memory alloy spring 3. At this time, shape memory alloy spring 3 rotates into the waste liquid and continues to be heated and contracted, driving the disk to rotate. The rotation of the disk simultaneously drives the generator to generate electricity. This device can realize the utilization of the thermal energy of industrial wastewater, and its structure is simple and easy to implement. The tilt angle of the disk is determined according to the actual contraction and elongation of the alloy to make fuller use of the thermal energy of the wastewater. After a series of processes, the temperature of the wastewater in tank 5 decreases, and it is finally discharged uniformly through outlet 11. If there is still residual heat that can be utilized after sufficient cooling, one or more treatment devices can be connected in series after tank 5. This process realizes the conversion of thermal energy into kinetic energy and then into electrical energy, so as to effectively utilize the wastewater heat.

[0033] In summary, the integrated water treatment device for waste heat power generation using shape memory alloy described in this invention effectively converts the heat energy in industrial wastewater into mechanical energy, and then into electrical energy, through the use of shape memory alloy springs and discs. This fully utilizes the waste heat resources in the wastewater, reduces energy waste, and features a simple structure that is easy to manufacture and maintain, thus lowering implementation costs.

[0034] The integrated water treatment device for waste heat power generation using shape memory alloy described in this invention utilizes the temperature-sensitive characteristics of shape memory alloy (high-temperature shrinkage, low-temperature elongation) to enable the device to operate automatically in a cyclical manner without the need for external power input, thus realizing the automation of waste heat utilization.

[0035] The integrated water treatment device for waste heat power generation using shape memory alloys described in this invention has strong overall scalability and adaptability. If the wastewater temperature is high and the waste heat is not fully utilized, multiple treatment devices can be connected in series to further recover the waste heat and improve energy utilization efficiency. The temperature-sensitive characteristics of different shape memory alloys enable them to adapt to wastewater of different temperatures. The device can adjust the tilt angle of the disc according to the actual wastewater temperature to optimize energy conversion efficiency. It can achieve intermittent operation by linking a water level sensor with a quick water exchange valve, completing batch replacement of wastewater, adapting to the intermittent discharge of industrial wastewater and the continuous operation requirements of industrial production lines, thus improving the flexibility and applicability of the device.

[0036] This invention discloses a comprehensive water treatment device for waste heat power generation using shape memory alloys. The device directly drives a disk to rotate by the contraction and elongation of the shape memory alloy, reducing energy loss during the conversion process and improving energy conversion efficiency. By recovering heat energy from wastewater, the device integrates wastewater treatment and waste heat power generation, reducing reliance on traditional energy sources. Combined heat and power generation lowers carbon emissions, promotes energy conservation and emission reduction, and is environmentally friendly, meeting the requirements of environmental protection and sustainable development.
