Description

Technical Field

[0001] The invention belongs to the technical field of heat exchange equipment, in particular to a vulcanizing machine exhaust steam energy-saving heat exchange system. Background Art

[0002] In the rubber products industry, vulcanizers are critical equipment in the production of products like conveyor belts. During the vulcanization process, high-temperature steam is used to heat the rubber, inducing a vulcanization reaction to achieve the desired physical and chemical properties. However, the exhaust steam formed after the steam transfer completes the heat transfer, although it still contains a significant amount of thermal energy, is often directly discharged. This not only results in significant energy waste but also has adverse environmental impacts such as thermal pollution. To recycle exhaust steam, the use of heat exchange equipment for vulcanizer exhaust steam heat exchange is becoming increasingly mainstream. This approach utilizes the latent heat of water vaporization to absorb heat from the exhaust steam, condensing the water vapor into water. Currently, there are several key approaches for efficiently utilizing the energy generated by heat exchange. In industrial production, the hot water from heat exchange can be used to preheat raw materials for rubber production, such as heating natural rubber to a suitable processing temperature, thereby reducing energy consumption during the subsequent vulcanization process. It can also be used to preheat water for cleaning rubber products, improving cleaning efficiency and reducing energy costs. In the domestic sector, the recovered heat can be used to heat the factory and surrounding areas, meeting winter heating needs for offices, workshops, and staff dormitories. It can also provide domestic hot water for employees in cafeterias, bathrooms, and other areas, achieving secondary energy utilization. Furthermore, by further increasing the temperature of the hot water after heat exchange, it can be used to drive absorption chillers to provide cooling services in the workshop during the summer, creating a "waste heat heating-waste heat cooling" cycle, maximizing energy efficiency and reducing the company's reliance on traditional energy sources.

[0003] However, when using a cooling tower to exchange exhaust steam, the exhaust steam will be introduced into the heat exchange equipment through a pipe, and the incoming exhaust steam will flow directly upward, resulting in local gas aggregation or uneven dispersion of the exhaust steam; for example, during the pressure relief stage of the vulcanizer, the exhaust steam will instantly enter the condenser at a high flow rate and pressure, which may cause the gas to form a strong jet near the condenser inlet, while the gas in the area far from the inlet is relatively less; when the exhaust steam is uneven, it will lead to the exhaust steam being unable to fully exchange heat, thereby reducing the heat exchange effect and failing to achieve efficient recovery and utilization of the exhaust steam waste heat.

[0013] The beneficial effects of the present invention are as follows: 1. The energy-saving heat exchange system for exhaust steam from a vulcanizing machine described in the present invention releases the exhaust steam by utilizing a rotating second through hole. Simultaneously, the exhaust steam is discharged sequentially through the first through hole while rotating, thereby allowing the exhaust steam to diffuse and improving the uniformity of the exhaust steam.

[0014] 2. The energy-saving heat exchange system for exhaust steam of a vulcanizing machine described in the present invention has a liquid bin provided under each of the multiple filling bins. When the exhaust steam passes through each liquid bin, the exhaust steam will contact the bottom of the liquid bin, and then flow and diffuse along the bottom of the liquid bin, thereby further diffusing the exhaust steam and improving the uniformity of the exhaust steam. At the same time, since there are multiple first vertical cylinders and second vertical cylinders, and the exhaust steam flows through the first vertical cylinder and the second vertical cylinder, the exhaust steam flowing through will be heat exchanged with the downwardly flowing water, thereby increasing the contact time between the exhaust steam and the water and further improving the heat exchange effect of the exhaust steam. At the same time, the number of the first through holes located in the liquid bin and the number of the second through holes exposed to the outside can be adjusted by changing the liquid level height, thereby allowing more water to contact more exhaust steam, thereby allowing more water to exchange heat with more exhaust steam, thereby improving the efficiency of exhaust steam heat exchange.

[0015] 3. In the energy-saving heat exchange system for exhaust steam of a vulcanizer described in the present invention, since the second vertical cylinder is connected to the annular tube, the water flowing out of the second vertical cylinder will enter the annular tube. At the same time, the water flowing out through the cylindrical groove will also flow into the annular tube through the connecting tube. The water in the annular tube will flow out through the evenly arranged second nozzles, thereby coming into contact with the upward-flowing exhaust steam again, further improving the heat exchange effect of the exhaust steam.

[0016] 4. The energy-saving heat exchange system for exhaust steam of a vulcanizing machine described in the present invention has an upwardly protruding middle portion of the first circular plate. When the exhaust steam flows to the top of the first circular plate, it will flow along the first circular plate. Since a one-way valve is installed in the first air hole, it can prevent water from flowing into the air chamber. At the same time, when the exhaust steam is ejected from the first air hole, it will come into contact with the water flowing through the first air hole and blow the water upward to diffuse. The water diffusing upward will exchange heat with the exhaust steam flowing through, thereby improving the heat exchange effect of the exhaust steam. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] As an embodiment of the present invention, Figures 1 to 9 As shown, the energy-saving heat exchange system for exhaust steam of a vulcanizing machine according to the present invention comprises a heat exchange device; the heat exchange device comprises a tower body 1; an air outlet pipe 11 is installed on the top of the tower body 1; The tower body 1 is provided with uniformly arranged filling bins 12; the filling bins 12 are provided with filling materials; two annular spray pipes 13 are fixedly installed on the top of the inner cavity of the tower body 1; the spray pipes 13 are provided with uniformly arranged first spray heads 14; A liquid inlet pipe 15 is installed on the outside of the tower body 1, and one side of the liquid inlet pipe 15 is connected to the spray pipe 13, and the other side is connected to the external water tank; An auxiliary mechanism is installed under each of the filling bins 12; An air silo 2 is fixedly installed at the bottom of the inner cavity of the tower body 1; an air inlet pipe 21 is installed on the air silo 2, and the air inlet pipe 21 extends to the outside; there is a distance between the air silo 2 and the inner cavity of the tower body 1; A first circular plate 22 is fixedly connected to the top of the air chamber 2; the first arc-shaped plate is provided with uniformly arranged first air holes 23 on its entire surface; a second circular plate 24 is rotatably connected to the air chamber 2, and the second circular plate 24 is in contact with the first circular plate 22; The second circular plate 24 has three rows of second air holes 25 on its surface; the second air holes 25 correspond to some of the first air holes 23 in the initial state; a motor 26 is installed at the bottom of the tower body 1; the drive shaft of the motor 26 extends into the air chamber 2 and is fixedly connected to the second circular plate 24; A liquid outlet pipe 16 is installed at the bottom of the tower body 1, and the other side of the liquid outlet pipe 16 is connected to the external water tank; During the heat exchange treatment of the exhaust steam, the water in the water tank is first introduced into the liquid inlet pipe 15. The water in the liquid inlet pipe 15 is then introduced into the spray pipe 13 and then evenly sprayed out from the first nozzle 14. The sprayed water then flows gradually downward through the filler. When the water reaches the bottom of the tower body 1, it flows out through the liquid outlet pipe 16 and flows back into the water tank. During the implementation process, the air intake pipe 21 is connected to the pipe for discharging exhaust steam on the vulcanizer, and then the high-temperature exhaust steam enters the air bin 2 through the air intake pipe 21. As the exhaust steam in the air bin 2 gradually increases, when the exhaust steam fills the air bin 2, the exhaust steam will be ejected through the three rows of second air holes 25. At the same time, the motor 26 is controlled to work, and the motor 26 will drive the second circular plate 24 to rotate. The rotating second circular plate 24 will drive the second air holes 25 to rotate. The rotating second air holes 25 will rotate around the first circular plate 22, so that they will overlap with the first air holes 23 on the first circular plate 22 in sequence. When the second air holes 25 overlap with the first air holes 23, the exhaust steam will be ejected through the first air holes 23 and gradually flow upward. In this process, the exhaust steam can be made to flow out from the first air holes 23 in sequence, thereby diffusing the exhaust steam, improving the uniformity of the exhaust steam, and avoiding the upward flow of exhaust steam accumulation. During the implementation process, when the dispersed exhaust steam passes through the packing, it will gradually move upward through the packing, and the water flowing downward will contact the exhaust steam, thereby realizing heat exchange with the exhaust steam. When the exhaust steam flows to the top, it will be discharged through the exhaust pipe 11. In this process, the exhaust steam is released by utilizing the rotating second through hole 35. At the same time, the exhaust steam is discharged through the first through hole 33 in sequence while rotating, so that the exhaust steam can be diffused and the uniformity of the exhaust steam is improved. When the diffused exhaust steam contacts the heat exchange water, the heat exchange effect with the exhaust steam can be improved, thereby avoiding the exhaust steam from being unable to fully exchange heat, thereby reducing the heat exchange effect and failing to achieve efficient recovery and utilization of the exhaust steam waste heat.

[0022] As an embodiment of the present invention, the auxiliary mechanism includes a liquid tank 3; A liquid tank 3 is fixedly installed below the filling tank 12; a conduit 17 is installed on the liquid inlet pipe 15, and the other side of the conduit 17 extends into the liquid tank 3; The liquid tank 3 is slidably connected with uniformly arranged first vertical cylinders 31, and the first vertical cylinders 31 partially extend to the bottom of the liquid tank 3; the top of each of the first vertical cylinders 31 is fixedly connected with a float 32; The outer surface of the first vertical cylinder 31 is provided with uniformly arranged first through holes 33; the bottom of the liquid tank 3 is fixedly mounted with uniformly arranged second vertical cylinders 34, and the first vertical cylinders 31 slide in the opposite second vertical cylinders 34; The outer surface of the second vertical cylinder 34 is provided with uniformly arranged second through holes 35, and the second through holes 35 are staggered with the first through holes 33; the sum of the water output of the first through holes 33 is less than the water inflow of the conduit 17; In this embodiment, a cylindrical groove 4 is formed in the side wall of the liquid tank 3; a notch 41 is formed on the side of the cylindrical groove 4 facing the first vertical tube 31, and the notch 41 is connected to the cylindrical groove 4; A cylinder 42 is slidably connected in the cylindrical groove 4; an electric push rod 43 is installed above the cylinder 42 and located in the inner wall of the filling bin 12; the other side of the electric push rod 43 is fixedly installed on the cylinder 42; During implementation, since the liquid tank 3 is connected to the liquid inlet pipe 15 through the conduit 17, when water is introduced into the liquid inlet pipe 15, the liquid will enter the liquid tank 3 through the conduit 17, and some of the water will enter the first vertical cylinder 31 through the first through hole 33, and then flow downward along the first vertical cylinder 31 and the second vertical cylinder 34. Since the sum of the water outflow of the first through hole 33 is less than the water inflow of the conduit 17, the water in the liquid tank 3 will gradually increase, and the liquid level in the liquid tank 3 will gradually rise. At the same time, the float 32 on the first vertical cylinder 31 will flow upward with the liquid level, driving the first vertical cylinder 31 to move upward. When the water in the filling bin 12 falls from the filling bin 12, it will also fall into the liquid tank 3. When the liquid level in the liquid tank 3 is flush with the cylinder 42, if the liquid level in the liquid tank 3 rises again, this part of the water will enter the cylinder 42 through the notch 41, and then be discharged by the cylinder 42, so as to ensure that the liquid level in the liquid tank 3 tends to be the same. During the implementation process, after the exhaust steam is discharged through the first air hole 23, the exhaust steam will flow upward, and part of the exhaust steam flowing upward will enter the second vertical cylinder 34 from the second through hole 35, and part of the gas will move up to the bottom of the liquid tank 3. When the exhaust steam is blocked by the liquid tank 3, it will diffuse along the bottom surface of the liquid tank 3, thereby further diffusing the exhaust steam. When the exhaust steam diffuses to the position of the second vertical cylinder 34, the exhaust steam will enter the second vertical cylinder 34 through the second through hole 35, and then flow along the second vertical cylinder 34 and the first vertical cylinder 31. At the same time, the water in the liquid tank 3 will pass through The first through hole 33 enters the first vertical tube 31 and then flows downward in the first and second vertical tubes 31 and 34, thereby contacting the exhaust steam flowing upward in the first and second vertical tubes 31 and 34, thereby exchanging heat with the exhaust steam. Since the first and second vertical tubes 31 and 34 are evenly arranged on the liquid tank 3, and since the exhaust steam flows upward after diffusion, the heat exchange efficiency of the exhaust steam can be improved. When the exhaust steam flows out from the top of the first vertical tube 31, it will be located between the liquid surface and the packing bin 12, and then the exhaust steam will pass through the packing bin 12 for heat exchange again. During implementation, since the cylinder 42 is connected to the electric push rod 43, controlling the electric push rod 43 to contract will drive the cylinder 42 to move upward along the cylindrical groove 4. When the cylinder 42 moves upward, the height of the top of the cylinder 42 becomes higher, so the liquid level in the liquid tank 3 will rise. When the liquid level rises, the float 32 will drive the first vertical cylinder 31 to move upward. After the first vertical cylinder 31 moves upward, more of the first vertical cylinder 31 is located in the liquid tank 3, so more of the first through holes 33 on the first vertical cylinder 31 will be located in the liquid tank 3. At the same time, since the first vertical cylinder 31 moves upward, part of the second through holes 35 on the second vertical cylinder 34 are no longer blocked by the first vertical cylinder 31. Therefore, more second through holes 35 on the second vertical cylinder 34 are exposed to the outside, so the exhaust steam entering the second vertical cylinder 34 through the second through holes 35 will increase, and the water flowing out through the first through holes 33 will increase, so that more water can be brought into contact with more exhaust steam, so that more water can be used to exchange heat with more exhaust steam, thereby improving the exhaust steam heat exchange efficiency; when the liquid level height rises, the distance between the liquid surface and the packing bin 12 will become smaller, so when the exhaust steam flows out through the top of the first vertical cylinder 31, it will flow between the liquid surface and the packing bin 12 and diffuse, and then flow upward through the packing to continue heat exchange; Generally speaking, since a liquid bin 3 is provided under each of the multiple filling bins 12, when the exhaust steam passes through each liquid bin 3, the exhaust steam will contact the bottom of the liquid bin 3, and then flow and diffuse along the bottom of the liquid bin 3, thereby further diffusing the exhaust steam and improving the uniformity of the exhaust steam. At the same time, since there are multiple first vertical cylinders 31 and second vertical cylinders 34, and the exhaust steam flows through the first vertical cylinder 31 and the second vertical cylinder 34, the exhaust steam flowing through will be heat exchanged by the downwardly flowing water, thereby increasing the contact time between the exhaust steam and the water and further improving the heat exchange effect of the exhaust steam. At the same time, the number of the first through holes 33 located in the liquid bin 3 and the number of the second through holes 35 exposed to the outside can be adjusted by changing the liquid level height, so that more water can be in contact with more exhaust steam, so that more water can be used to exchange heat with more exhaust steam, thereby improving the efficiency of exhaust steam heat exchange.

[0023] As an embodiment of the present invention, the top of each of the first vertical cylinders 31 is fixedly connected with a horizontal plate; Each of the horizontal plates is fixedly connected to a vertical rod 36; a disk 37 is fixedly connected to the top of the vertical rod 36; the middle of the disk 37 is upwardly protruding; there is a distance between the disk 37 and the top of the first vertical cylinder 31; In this embodiment, the vertical rod 36 extends to the bottom of the first vertical cylinder 31; The vertical rod 36 is fixedly connected to a guide shaft 38 , and the diameter of the middle portion of the guide shaft 38 is larger than the diameters of the top and bottom portions of the guide shaft 38 ; In this embodiment, two annular tubes 44 are provided at the bottom of the liquid tank 3 , wherein one annular tube 44 is located inside the other annular tube 44 ; The second vertical tubes 34 extend downward and extend into the interior of the opposite annular tube 44; a one-way valve is installed on one side of the second vertical tube extending into the annular tube 44; A connecting pipe 45 is installed at the bottom of the cylindrical tank 4, and the other side of the connecting pipe 45 extends into the annular pipe 44; a second nozzle 46 is installed at the bottom of the annular pipe 44, and the second nozzle 46 is connected to the annular pipe 44; During implementation, since the bottom of the first vertical tube 31 is provided with an upwardly protruding disc 37, when the exhaust steam flows out through the top of the first vertical tube 31, the exhaust steam will flow along the disc 37 and diffuse toward the periphery, thereby preventing the gas flowing out of the first vertical tube 31 from flowing vertically upward, which would cause the exhaust steam to accumulate. Since the vertical rod 36 is provided with a guide shaft 38, when the exhaust steam or water passes through, they will flow along the guide shaft 38. The exhaust steam and water flowing through will come into contact with each other, thereby extending the contact time between the exhaust steam and water and improving the heat exchange effect. During implementation, since the second vertical cylinder 34 is connected to the annular tube 44, the water flowing out of the second vertical cylinder 34 will enter the annular tube 44. At the same time, the water flowing out through the cylindrical groove 4 will also flow into the annular tube 44 through the connecting pipe 45. The water in the annular tube 44 will flow out through the evenly arranged second nozzles 46, and will come into contact with the upward-flowing exhaust steam again, further improving the heat exchange effect of the exhaust steam.

[0024] As an embodiment of the present invention, an annular partition plate 47 is provided between the two annular tubes 44, and the cross section of the annular partition plate 47 is V-shaped; In this embodiment, the middle portions of the first circular plate 22 and the second circular plate 24 are both convex upwards; a one-way valve is installed in each of the first air holes 23; In this embodiment, a protrusion 5 is provided between the gas chamber 2 and the tower body 1, and the protrusion 5 is fixedly connected to the driving shaft of the motor 26; The protrusion 5 is fixedly connected with push plates 51 arranged evenly; During implementation, since an annular partition 47 is provided between the two annular tubes 44, when the exhaust steam flows upward, the exhaust steam will be guided to flow toward the position of the second nozzle 46, thereby preventing the exhaust steam from being misaligned with the water sprayed from the second nozzle 46; During the implementation process, since the middle part of the first circular plate 22 is convex upward, when the water flows above the first circular plate 22, it will flow along the first circular plate 22. Since a one-way valve is installed in the first air hole 23, it can prevent water from flowing into the air chamber 2. At the same time, when the exhaust steam is ejected from the first air hole 23, it will come into contact with the water flowing through the first air hole and blow the water upward to diffuse. The upwardly diffused water will exchange heat with the exhaust steam flowing through, thereby improving the heat exchange effect of the exhaust steam. During implementation, when water flows to the bottom of the air chamber 2, the motor 26 will drive the protrusion 5 and the push plate 51 to rotate. The rotating push plate 51 will push the water to move and mix the water, and then discharge it through the liquid outlet pipe 16.
