[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Combination Figures 1-12 As shown, a waste heat utilization power generation system for textile enterprises according to the present invention includes a textile drying box 1, and further includes: The collecting pipe 2 is installed on the textile drying box 1 and is interconnected with the textile drying box 1; Heat exchange tower 3 is installed on and connected to the collecting pipe 2. Heat from the textile drying box 1 can enter the heat exchange tower 3 through the collecting pipe 2. Rotary heat conduction component 9 is also installed in the heat exchange tower 3. Steam heating unit 4 is installed on the side wall of textile drying box 1, and the steam heating unit 4 is also filled with water; The heating and drying unit 5 is located on another side wall of the textile drying box 1. The heating and drying unit 5 passes through the collecting pipe 2, which is used to draw in external gas and transport it into the textile drying box 1 to heat the inside of the textile drying box 1. The collecting pipe 2 can preheat the external gas. The circulating pumping unit 6 is disposed on the steam heating unit 4 and interconnected with the steam heating unit 4 and the rotating heat conduction component 9. It is used to pump water in the steam heating unit 4 into the rotating heat conduction component 9, heat the water through the rotating heat conduction component 9 and pump it into the steam heating unit 4 to generate steam in the steam heating unit 4. Steam power generation unit 7 is installed on and connected to steam heating unit 4. It is used to collect steam and generate electricity to supply textile enterprises.

[0021] During the operation of the textile drying box 1, the waste heat generated inside is effectively collected through the collecting pipe 2 and guided to the heat exchange tower 3. Inside the heat exchange tower 3, the rotating heat conduction component 9 increases the contact area with the waste heat from the textile drying box 1 by its own rotational motion, thereby improving the heat energy conversion efficiency. In this process, the waste heat is fully absorbed and converted into the heat energy of the rotating heat conduction component 9. At the same time, the steam heating unit 4, as another key component of the system, is filled with water. The circulation pumping unit 6 starts working, drawing water out of the steam heating unit 4 and transporting it to the rotating heat conduction component 9. In the rotating heat conduction component 9, the water is heated by the waste heat, and then pumped back to the steam heating unit 4 by the circulation pumping unit 6. As the water temperature gradually increases... As the temperature rises, steam begins to be generated inside the steam heating unit 4. To further improve the heating efficiency of the textile drying box 1, the heating and drying unit 5 is installed on another side wall of the textile drying box 1. The heating and drying unit 5 passes through the collecting pipe 2 and uses the collecting pipe 2 to preheat the external gas. The preheated external gas is transported into the textile drying box 1 to exchange heat with the textiles, thereby realizing the heating and drying of the textiles. As steam is generated inside the steam heating unit 4, the steam power generation unit 7 starts to work. The steam power generation unit 7 is interconnected with the steam heating unit 4, collects the steam from the steam heating unit 4, and uses the steam to drive the generator to generate electricity. The generated electricity can be supplied to textile enterprises to meet their daily production and living electricity needs.

[0022] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 , Figure 7As shown; the collecting pipe 2 is arranged along the length of the textile drying box 1. The textile drying box 1 also has several transmission pipes 8, which are divided into two rows, located outside the collecting pipe 2 and interconnected with it. Heat from inside the textile drying box 1 can be transferred to the collecting pipe 2 through the transmission pipes 8. Both ends of the collecting pipe 2 are closed. This arrangement allows the collecting pipe 2 to receive heat from inside the textile drying box 1 more evenly. During the drying process, the textile drying box 1 generates a large amount of residual heat, which is effectively collected and transferred through the transmission pipes 8. The heat transfer pipe 8 is divided into two equal rows on the textile drying box 1, and is set on the outside of the gathering pipe 2 and connected to the gathering pipe 2. This design not only increases the heat transfer path, but also improves the heat transfer efficiency. The heat in the textile drying box 1 can flow smoothly into the gathering pipe 2 through the guidance of the transfer pipe 8, avoiding heat loss and waste. It is worth noting that both ends of the gathering pipe 2 are closed. This design ensures the stability and concentration of heat inside the gathering pipe 2, and avoids heat loss and dispersion. After the heat is transferred to the gathering pipe 2, through the action of the heat exchange tower 3 and the rotating heat conduction component 9, this heat is further converted and utilized, and finally used for power generation.

[0023] In a preferred embodiment, the present invention may be further configured as follows: Figures 1 to 4 As shown; the steam heating unit 4 includes: The heat exchange box 41 is fixedly installed on the side wall of the textile drying box 1; The spiral heat exchange tube 42 is fixedly installed inside the heat exchange box 41. The spiral heat exchange tube 42 has two ports, namely the liquid inlet and the liquid outlet. Both ends of the spiral heat exchange tube 42 pass through and extend to the outside of the heat exchange box 41. The heat-conducting sleeve 43 is fixedly installed on the outside of the transmission pipe 8, and the spiral heat exchange tube 42 and the space between the heat-conducting sleeve 43 and the transmission pipe 8 are filled with heat-conducting oil. Pump body 44 is fixedly installed on the surface of heat exchange box 41, wherein the suction end of pump body 44 is connected to the liquid outlet of spiral heat exchange tube 42, and a first liquid delivery pipe 45 is fixedly installed at the liquid outlet end of pump body 44, which extends through and into heat-conducting sleeve 43. The second infusion pipe 46 has one end penetrating the heat-conducting sleeve 43 and extending between the heat-conducting sleeve 43 and the transmission pipe 8, and the other end communicating with the inlet of the spiral heat exchange pipe 42. The heat exchange box 41 is fixedly installed on the side wall of the textile drying box 1, serving as the main site for heat exchange. The spiral heat exchange pipe 42 is fixedly installed inside the heat exchange box 41. Its special spiral shape design increases the heat exchange area and improves thermal efficiency. The spiral heat exchange pipe 42 has two ports, namely the inlet and the outlet, both of which penetrate and extend to the outside of the heat exchange box 41, facilitating connection with components such as the pump body 44, the first infusion pipe 45, and the second infusion pipe 46. The heat-conducting sleeve 43 is fixedly installed on the outside of the transmission pipe 8, forming a sealed space with the transmission pipe 8. This space, as well as the spiral heat exchange pipe 42, is filled with heat-conducting oil. As a highly efficient heat transfer medium, the heat-conducting oil can rapidly transfer heat from the high-temperature region to the low-temperature region. When the high-temperature gas in the textile drying box 1 enters the collecting pipe 2 through the transmission pipe 8... At this time, the high-temperature gases heat the heat transfer oil between the heat transfer sleeve 43 and the transmission pipe 8. The pump body 44 then starts working, its suction end connected to the liquid outlet of the spiral heat exchange tube 42, drawing out the heat transfer oil from the spiral heat exchange tube 42 and transferring it to the heat transfer sleeve 43 through the first liquid delivery pipe 45. Subsequently, the heat transfer oil flows out of the heat transfer sleeve 43 through the second liquid delivery pipe 46 and re-enters the liquid inlet of the spiral heat exchange tube 42, thus forming a circulating transmission path. During this circulation process, the heat transfer oil continuously transfers the heat from the high-temperature gases in the textile drying box 1 to the water in the heat exchange box 41, causing the water temperature to gradually rise and eventually generate steam. The generated steam can be utilized by the subsequent steam power generation unit 7 for power generation, thereby providing additional energy supply for textile enterprises. Through this design, the steam heating unit 4 achieves efficient recovery and utilization of the waste heat from the high-temperature gases in the textile drying box 1, not only reducing the enterprise's energy consumption costs but also improving energy utilization and environmental protection levels. It should also be noted that... Figure 4 The direction indicated by the middle arrow is the direction of water flow.

[0024] In a preferred embodiment, the present invention may be further configured as follows: Figure 5 , Figure 6 and Figure 7 As shown; the heating and drying unit 5 includes: The first connecting seat 51 is fixedly installed at the end of the collecting tube 2, and a filter screen 52 is embedded on its surface; The second connecting seat 53 is fixedly installed on the other end of the collecting tube 2, and is arranged parallel to the first connecting seat 51. A connecting circular tube 54 is installed through the collecting tube 2, with one end connected to the first connecting seat 51 and the other end connected to the second connecting seat 53. The number of connecting circular tubes 54 is set to a certain extent and they are distributed in a ring at equal intervals around the center of the second connecting seat 53. The equal distribution pipe 55 has one end connected to the second connecting seat 53, and the other end of the equal distribution pipe 55 is closed. Heating box 56 is fixedly installed on another side wall of textile drying box 1. Heating unit is provided inside. There are several heating boxes 56 and they are evenly distributed. Several heating boxes 56 are connected to textile drying box 1. Air pumps 57 are fixedly installed on the side wall of heating chamber 56, their number and distribution matching that of heating chamber 56. A vertical pipe 58 is connected to the suction end of air pump 57, and the other end of the vertical pipe 58 is connected to a distribution pipe 55. The outlet end of air pump 57 extends through and into the inner side of heating chamber 56. Filter screen 52 is used to filter incoming gas from the outside to prevent impurities from entering the system. Second connecting seat 53 is fixedly installed at the other end of collecting pipe 2, parallel to the first connecting seat 51, together forming the gas inlet and outlet channels. The design of connecting circular pipe 54 allows gas to flow evenly and smoothly inside collecting pipe 2. Distribution pipe 55 is used to evenly distribute gas to each air pump 57. Heating chamber 56 is used to heat the gas entering textile drying chamber 1. Furthermore, there are several heating chambers 56, which are evenly distributed to ensure that the gas can be heated evenly and fully. When the air pump 57 is working, it draws in the outside gas. This gas first passes through the filter screen 52 into the corresponding first connecting seat 51, then through the connecting round pipe 54 into the second connecting seat 53, and then through the equalization pipe 55 to distribute it to each air pump 57. When the gas passes through the connecting round pipe 54, due to the action of the high temperature gas in the collecting pipe 2, this fresh gas can be preheated, thereby increasing the gas temperature and reducing the energy consumption of the heating chamber 56. Subsequently, the air pump 57 pumps the preheated gas into the heating chamber 56. After being further heated by the heating unit, this high temperature gas is sent into the textile drying chamber 1 to dry the textiles.

[0025] In a preferred embodiment, the present invention may be further configured as follows: Figures 9 to 12 As shown; the rotating heat-conducting assembly 9 includes: Mounting bracket 91 is fixedly installed on the inner side of heat exchange tower 3. There are two mounting brackets 91, which are arranged vertically and parallel to each other. The turbine blades 92 are rotatably connected to the inner side of the mounting bracket 91, and their number and distribution are adapted to the mounting bracket 91. Hollow tube 93 is fixedly installed at the center of turbine blade 92, and can be driven to rotate axially under the action of turbine blade 92; Two sealed bearings 94 are provided on the outside of the hollow tube 93, wherein the inner ring of the sealed bearing 94 is connected to the outside of the hollow tube 93. An outer ring 95 is disposed on the outside of two sealed bearings 94, wherein the outer ring 95 is connected to the outer ring of the sealed bearings 94, and the area enclosed by the outer ring 95, the two sealed bearings 94 and the hollow tube 93 is a liquid storage area. A heat-conducting component 96 is disposed on the outside of the hollow tube 93, used to conduct heat from the heat exchange tower 3 to the hollow tube 93. The mounting bracket 91 provides stable support for the entire rotating heat-conducting assembly 9. The turbine blades 92 are rotatably connected to the inside of the mounting bracket 91, their number and distribution matching the bracket 91 to ensure that the gas can fully contact the turbine blades 92 and generate rotational power during flow. When gas enters the heat exchange tower 3, it blows the turbine blades 92 to rotate. The hollow tube 93 is fixedly installed at the center of the turbine blades 92. As the turbine blades 92 rotate, the hollow tube 93 also rotates axially. This design allows the hollow tube 93 to fully contact and absorb heat from the heat exchange tower 3. To ensure the hollow tube 93... 3. During rotation, the outer ring 95 will not rotate with it. Two sealed bearings 94 are provided. The inner ring of the sealed bearing 94 is connected to the outer side of the hollow tube 93, while the outer ring 95 is located on the outside of the two sealed bearings 94 and connected to the outer ring of the sealed bearings 94. In this way, a closed liquid storage area is formed between the outer ring 95, the two sealed bearings 94 and the hollow tube 93 for storing water. The heat-conducting component 96 is located on the outside of the hollow tube 93. It can efficiently conduct heat from the heat exchange tower 3 to the hollow tube 93. As the hollow tube 93 rotates, the heat-conducting component 96 also rotates, so that the gas can come into uniform contact with the heat-conducting component 96 during the rise of the heat exchange tower 3, thereby improving the heat recovery effect.

[0026] In a preferred embodiment, the present invention may be further configured as follows: Figure 10 , Figure 11 As shown; the heat-conducting component 96 includes: The heat-conducting ring 961 is fixedly installed on the outside of the hollow tube 93, and there are several of them, which are evenly distributed. Conductive blades 962 are fixedly installed on the outside of heat-conducting rings 961, wherein each heat-conducting ring 961 has several conductive blades 962 on its outside and they are distributed in a ring at equal intervals. The heat pipe 963 has one end fixedly installed inside the heat-conducting ring 961, and the other end extending through and into the inner side of the hollow tube 93. The addition of the conductive blades 962 greatly increases the contact area between the heat-conducting component 96 and the heat inside the heat exchange tower 3, thereby improving the heat transfer efficiency. When the hot air flows through the heat exchange tower 3, the heat will be quickly transferred to the heat-conducting ring 961 through the conductive blades 962. One end of the heat pipe 963 is fixedly installed inside the heat-conducting ring 961, and the other end extends through and into the inner side of the hollow tube 93. This design allows the heat absorbed on the heat-conducting ring 961 to be efficiently transferred to the water inside the hollow tube 93 through the heat pipe 963. Because the heat pipe 963 has good thermal conductivity, it can quickly transfer the heat on the heat-conducting ring 961 to the water inside the hollow tube 93, thereby achieving efficient heat recovery and utilization.

A leakage hole 63 is provided on the outer wall of the hollow tube 93, wherein the leakage hole 63 is located within the liquid storage area; The outlet pipe 64 has one end passing through the outer ring 95 and extending into the liquid storage area, and the other end passing through and extending into the inner side of the heat exchange box 41. The water pump 61 is fixedly installed on the surface of the heat exchange box 41, and its suction end passes through and extends into the inner side of the heat exchange box 41 to draw water from the heat exchange box 41. When the water pump 61 starts, it draws the water in the heat exchange box 41 into the hollow tube 93 through the inlet pipe 62. At this time, the water in the hollow tube 93 is heated to boiling under the action of the heat-conducting component 96. The leakage hole 63 is opened on the outer wall of the hollow tube 93 and is located in the liquid storage area. As the liquid level rises, the water will flow out from these leakage holes 63 into the liquid storage area. The water in the liquid storage area will be transported back into the heat exchange box 41 through the outlet pipe 64. In the heat exchange box 41, the water will be heated again by the steam heating unit 4 to form steam, thereby realizing continuous heat circulation and efficient utilization.

The liquid level sensor 10 can monitor the water level change in the heat exchanger 41 in real time and feed this information back to the control system. When the water level is lower than a preset threshold, the control system will trigger an alarm or automatically start the filling mechanism to ensure that the water level in the heat exchanger 41 is always kept within a suitable range, thereby ensuring the normal operation of the system and the heat exchange efficiency. To facilitate water filling operations in the heat exchanger 41, a filling pipe 11, with one end penetrating and extending into the heat exchanger 41, is also provided on its surface. The filling pipe 11 inside the heat exchange box 41 allows water to be added to the heat exchange box 41 until the required water level is reached. In addition, to ensure that the hollow tube 93 does not rotate with the water inlet pipe 62 during rotation, thus affecting the stability and safety of the system, the surface of the hollow tube 93 is provided with a mounting hole, and a connecting sealing bearing 12 is installed in the mounting hole. The outer ring of the connecting sealing bearing 12 is fixedly connected to the inner wall of the mounting hole, while the inner ring is connected to the water inlet pipe 62. This design not only achieves a stable connection between the hollow tube 93 and the water inlet pipe 62, but also ensures the sealing and reliability of the two during relative movement. Even if the hollow tube 93 rotates at high speed under the drive of the turbine blades 92, the water inlet pipe 62 can remain stationary, thereby avoiding problems such as friction and leakage caused by rotation.

[0029] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 As shown; the steam power generation unit 7 includes: Steam pipe 71, one end of which passes through and extends into the inside of heat exchange box 41; The main manifold 72 is connected to the other end of the steam pipe 71; Steam turbine 73 is located at the end of manifold 72. Steam from heat exchanger 41 can be introduced into steam turbine 73 via steam pipe 71 and manifold 72. One end of steam pipe 71 extends through and into the inside of heat exchanger 41 to draw out steam generated by hot water evaporation within heat exchanger 41. Inside heat exchanger 41, circulating pump unit 6 continuously heats water to boiling, generating a large amount of steam. This steam is guided to the next component of the system via steam pipe 71. Manifold 72 is connected to the other end of steam pipe 71, serving to collect and aggregate steam. Since multiple textile drying facilities are located within the textile enterprise... The steam generator unit 7 consists of a steam tank 1 and multiple steam pipes 71. The design of the main pipe 72 ensures that steam from all the steam pipes 71 can be effectively collected and introduced into the steam turbine 73. The steam turbine 73 is located at the end of the main pipe 72 and is the core component of the steam power generation unit 7. When steam is introduced into the steam turbine 73 through the steam pipes 71 and the main pipe 72, the high-speed flow of steam will drive the blades of the steam turbine 73 to rotate, thereby converting the internal energy of the steam into mechanical energy. In this process, the steam turbine 73 and the generator are not explicitly shown in the diagram, but they are usually connected and work together with the steam turbine to convert mechanical energy into electrical energy and realize the power generation utilization of steam.

[0030] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 , Figure 7 As shown, a breathable dustproof net 13 is installed on the inner side of the heat exchange tower 3. The lowest end of the breathable dustproof net 13 is higher than the lowest end of the upper mounting bracket 91. By introducing the design of the breathable dustproof net 13, on the one hand, it can effectively block dust, particulate matter and other impurities in the external environment from entering the interior of the heat exchange tower 3, avoiding the contamination and damage of these impurities to the internal components of the system, thereby extending the service life of the system; on the other hand, the breathable dustproof net 13 also has good air permeability, which can ensure the free circulation of air inside the heat exchange tower 3, which is crucial for maintaining the heat exchange efficiency of the system.

[0031] The specific working principle of a waste heat comprehensive utilization power generation system for textile enterprises according to the present invention is as follows: When using the waste heat utilization power generation system of this textile enterprise, firstly, the high-temperature gas in the textile drying box 1 enters the collecting pipe 2 through several transmission pipes 8. When the high-temperature gas passes through the transmission pipes 8, it heats the heat transfer oil between the heat transfer sleeve 43 and the transmission pipe 8. The heat transfer oil is circulated to the inside of the spiral heat exchange tube 42 by the action of the pump body 44 and the transmission of the first liquid delivery pipe 45 and the second liquid delivery pipe 46, thereby heating the water in the heat exchange box 41 to generate steam. The water pump 61 of the circulating pumping unit 6 draws water from the heat exchange box 41 into the hollow tube 93 through the water inlet pipe 62. The high-temperature gas in the textile drying box 1 also enters the heat exchange tower 3 through the collecting pipe 2. Inside the heat exchange tower 3, the gas blows the air wheel blades 92 of the rotating heat-conducting component 9 to rotate, which in turn drives the hollow tube 93 to rotate. The heat-conducting ring 961 and the conduction blades 962 of the heat-conducting component 96 rotate with the hollow tube 93, so that the gas and the heat-conducting component 96 are in uniform contact, improving the heat recovery effect. The heat in the heat exchange tower 3 is transferred to the heat-conducting ring 961 through the conduction blades 962, and then conducted to the water in the hollow tube 93 through the heat pipe 963 to heat it. After being heated by the heat-conducting component 96, the water flows out through the leakage hole 63 into the storage area, and then the boiling water is transferred back to the heat exchange box 41 through the water outlet pipe 64 to continuously generate steam. The steam generated in the heat exchange box 41 is introduced into the steam turbine 73 through the steam pipe 71 and the main pipe 72 to generate electricity and supply the textile enterprise. In addition, the air pump 57 of the heating and drying unit 5 is working, so that the outside gas enters the first connecting seat 51 through the filter screen 52, then enters the second connecting seat 53 through the connecting round pipe 54, and then enters each air pump 57 through the distribution pipe 55. The air pump 57 pumps the gas into the heating box 56. After compensation by the heating unit, the gas enters the textile drying box 1 for drying. When the gas passes through the connecting round pipe 54, it will be preheated by the high temperature in the collecting pipe 2, which improves the comprehensive utilization effect of waste heat. Throughout the process, the water level in the heat exchange box 41 is monitored by the liquid level sensor 10, and water is replenished in a timely manner through the injection pipe 11. At the same time, the breathable dustproof net 13 in the heat exchange tower 3 prevents dust from entering and ensures the normal operation of the system.
