[0022] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0024] A device for recovering waste heat from high-temperature exhaust gas from a modified nitrile rubber vulcanization furnace according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0025] See also Figure 1-Figure 10 According to an embodiment of the present application, a high-temperature exhaust gas waste heat recovery device of a modified nitrile rubber vulcanization furnace includes: a flue gas passing main body part 10 and a heat exchange part 20.

[0026] Among them, by the cooperation of the flue gas passing through the main body part 10 and the heat exchange part 20, compared with the traditional flue gas hot air, the waste heat in the exhaust gas generated by the vulcanization furnace during the modified nitrile rubber vulcanization operation can be recovered more efficiently.

[0027] See also Figure 1-Figure 3 , the smoke passes through the main body 10 including an outer box shell 110. A smoke inlet pipe 120 is arranged below one end of the outer box shell 110, and a smoke outlet pipe 130 is arranged above one end of the outer box shell 110. The heat exchange part 20 includes a first rotating box 210, a second rotating box 220, a heat conducting pipe 230, a heat conducting plate 240 and a rotating drive assembly 270. The first rotating box 210 and the second rotating box 220 are respectively arranged inside the outer box shell 110, and the two ends of the heat conducting pipe 230 are connected to the first rotating box 210 and the second rotating box 220 respectively. The heat conducting plate 240 is welded to the outside of the heat conducting pipe 230, and the first rotating box 210 is connected to the side away from the heat conducting pipe 230 with a liquid inlet pipe 250 that runs through the end of the outer box shell 110. The rotation driving assembly 270 is installed on the outer box shell 110 to drive the liquid inlet pipe 250 to rotate. The side of the second rotating box 220 away from the heat pipe 230 is connected to the liquid outlet pipe 260 that passes through the end of the outer box shell 110.

[0028] The working principle of the high-temperature waste gas waste heat recovery device of the modified nitrile rubber vulcanization furnace is as follows: the high-temperature flue gas generated by the vulcanization furnace enters the outer box shell 110 through the smoke inlet pipe 120 at the bottom of one end of the outer box shell 110, and the flue gas passes through the second rotating box 220 and the first rotating box 210, and is finally discharged from the smoke outlet pipe 130. At the same time, the external cold water enters the first rotating box 210 through the liquid inlet pipe 250, and the cold water inside the first rotating box 210 passes through a plurality of heat conducting pipes 230 between the first rotating box 210 and the second rotating box 220. The heat in the flue gas passing through the second rotating box 220 and the first rotating box 210 is quickly transferred to the cold water inside the heat conducting pipe 230 through the plurality of heat conducting plates 240 outside the heat conducting pipe 230, so that the cold water inside the heat conducting pipe 230 can be quickly heated. The heated cold water enters the second rotating box 220 through the heat conducting pipe 230, and is finally discharged through the liquid outlet pipe 260. The rotation drive assembly 270 can drive the liquid inlet pipe 250 to rotate, that is, drive the first rotating box 210, the second rotating box 220, and the heat conducting pipe 230 and the heat conducting plate 240 therebetween to rotate simultaneously, and the rotating heat conducting pipe 230 and the heat conducting plate 240 can have more contact with the flue gas circulating inside the outer box shell 110, that is, can further improve the absorption and heat conduction efficiency of the heat conducting pipe 230, so that the high-temperature exhaust gas waste heat recovery device has a higher heat exchange efficiency than the traditional flue gas heat exchanger.

[0029] Among them, in order to enable the high-temperature exhaust gas waste heat recovery device to have a better heat absorption and recovery effect, an insulation layer can be set on the inner wall of the outer box shell 110, so that the heat entering the outer box shell 110 is not easy to diffuse outward through the flue gas through the main body 10, so that the high-temperature exhaust gas waste heat recovery device as a whole has a better heat absorption and recovery effect.

[0030] For specific settings, see Figure 4 The rotation drive assembly 270 includes a motor 271, a driving sprocket 272, a driven sprocket 273 and a chain 274. The driven sprocket 273 is fixedly sleeved on the outside of the liquid inlet pipe 250, the motor 271 is installed on the outside of the end of the outer box shell 110, and the output shaft end of the motor 271 rotates and penetrates the end of the outer box shell 110. The driving sprocket 272 is fixedly sleeved on the end of the motor 271, and the chain 274 connects the driving sprocket 272 and the driven sprocket 273. The motor 271 in the rotation drive assembly 270 drives the driving sprocket 272 at the output shaft end to rotate, and the rotating driving sprocket 272 drives the liquid inlet pipe 250 to rotate through the cooperation of the driven sprocket 273 and the chain 274, and the rotating liquid inlet pipe 250 thereby drives the heat pipe 230 and the heat conducting plate 240 between the first rotating box 210 and the second rotating box 220 to rotate.

[0031] Furthermore, the rotation drive assembly 270 further includes a bearing seat 275, which is mounted on the inner bottom side of the outer housing 110, and the output shaft end of the motor 271 is plugged into the bearing seat 275. The bearing seat 275 is provided to support the shaft end of the motor 271, that is, to improve the stability of the driving sprocket 272 when rotating.

[0032] See also Figure 5 The high-temperature waste gas waste heat recovery device of the modified nitrile rubber vulcanization furnace also includes a flow regulating part 30, which is respectively installed inside the smoke inlet pipe 120 and the smoke outlet pipe 130 to adjust the smoke flow. The flow regulating part 30 includes an end pipe 310, a shaft rod 320, a baffle 330, a connecting plate 340, a fixing plate 350 and a plug-in 370. The end pipe 310 is fixed to the outer wall of the smoke inlet pipe 120, the fixing plate 350 is fixed to the outer end of the end pipe 310, the shaft rod 320 rotates to penetrate the smoke inlet pipe 120, the end pipe 310 and the fixing plate 350, the connecting plate 340 is fixed to one end of the shaft rod 320, the baffle 330 is fixed on the shaft rod 320, and a plurality of positioning openings 360 are arranged on the outer edge of the fixing plate 350, and the plug-in 370 is arranged on the connecting plate 340 to cooperate with the positioning opening 360 to adjust the inclination angle of the baffle 330.

[0033] The flow regulating part 30 can regulate the flow of smoke in the smoke inlet pipe 120 and the smoke outlet pipe 130. The specific regulating method is: the angle of the rotating shaft 320 and the baffle 330 thereon is adjusted by the plug-in 370 cooperating with the positioning hole 360 ​​on the fixing plate 350, and after the angle adjustment of the baffle 330 is completed, the plug-in 370 is plugged and matched with the positioning hole 360, so that the baffle 330 is positioned after the angle adjustment.

[0034] For details, please refer to Figure 6 The plug-in connector 370 includes a torsion block 371, a plug rod 372, a first limiting ring 373, a spring 374, and a second limiting ring 375. The plug rod 372 movably penetrates the connecting plate 340, the first limiting ring 373 and the second limiting ring 375 are both fixedly sleeved on the outside of the plug rod 372 located on both sides of the connecting plate 340, the spring 374 is sleeved on the outside of the plug rod 372 located between the second limiting ring 375 and the connecting plate 340, and the torsion block 371 is set at one end of the plug rod 372. When the torsion block 371 is pulled outward, the second limiting ring 375 on the outside of the plug rod 372 will compress the spring 374 between the connecting plate 340. Then rotate the connector 370 to drive the shaft 320 to rotate through the connecting plate 340. After the blocking piece 330 on the shaft 320 rotates to the specified angle, release the torsion block 371. Under the elastic force of the spring 374, the end of the plug rod 372 will be inserted into the positioning hole 360 ​​on the fixing plate 350, thereby fixing the blocking piece 330 after the tilting angle.

[0035] For specific settings, see Figure 1The main part 10 for passing the flue gas further includes a leg frame 140, which is fixed by bolts at the bottom of the outer shell 110 to support the waste heat recovery device as a whole. The main part 10 for passing the flue gas further includes an inspection plate 150, which is detachably mounted on one side of the outer shell 110. By opening the inspection plate 150 on one side of the outer shell 110, the heat exchange part 20 inside the outer shell 110 can be inspected and maintained.

[0036] In the above specific implementation, please refer to Figure 2 The liquid inlet pipe 250 includes a liquid inlet moving pipe 251 and a liquid inlet static pipe 252. One end of the liquid inlet moving pipe 251 is connected to the first rotating box 210, and one end of the liquid inlet moving pipe 251 is connected to the liquid inlet static pipe 252 through a rotating joint, and the liquid inlet static pipe 252 is set through the end of the outer box shell 110. The liquid outlet pipe 260 includes a liquid outlet moving pipe 261 and a liquid outlet static pipe 262. One end of the liquid outlet moving pipe 261 is connected to the second rotating box 220, and the other end of the liquid outlet moving pipe 261 is connected to one end of the liquid outlet static pipe 262 through a rotating joint, and the liquid outlet static pipe 262 is set through the end of the outer box shell 110. Among them, the rotating joint is a commonly used rotating joint structure.

[0037] After the flue gas in the above-mentioned modified nitrile rubber vulcanization furnace high-temperature exhaust gas waste heat recovery device enters the outer box shell 110 through the smoke inlet pipe 120, since multiple groups of heat pipes 230 and heat conductive plates 240 are arranged between the first rotating box 210 and the second rotating box 220, it is difficult for the multiple groups of heat pipes 230 and heat conductive plates 240 to absorb heat evenly, and it is impossible to maximize the thermal conductivity efficiency of the heat conductive plates 240 outside the heat pipes 230.

[0038] In the above specific settings, please refer to Figure 2 , Figure 3 , Figure 7 and Figure 8The first rotating box 210 and the second rotating box 220 have the same structural specifications. The first rotating box 210 includes a first outer frame 211, a first inner ring plate 212 and a box body 213. The first outer frame 211 is fixed inside the outer box shell 110, the first inner ring plate 212 is fixed outside the box body 213 and is rotatably arranged with the first outer frame 211, a smoke outlet 214 is arranged on the side of the first outer frame 211, and a water outlet 215 communicating with the heat pipe 230 is arranged on one side of the box body 213. A support and flow guide component 280 is arranged in the middle position inside the outer box shell 110, and the support and flow guide component 280 includes a second outer frame 281, a second inner ring plate 282 and a disc plate 283. The second outer frame 281 is fixed to the inner wall of the outer box shell 110, and the second inner ring plate 282 is fixed to the outer ring of the disc plate 283 and rotates with the second outer frame 281. A flow guide port 286 is arranged in the middle of the disc plate 283, and the side surfaces of the disc plate 283 are respectively provided with a socket 284 and a positioning groove 285 that cooperate with the heat pipe 230 and the heat conducting plate 240.

[0039] The high-temperature smoke enters the cavity on one side of the second rotating box 220 in advance through the smoke inlet pipe 120. At this time, the high-temperature smoke enters the cavity between the second rotating box 220 and the supporting guide assembly 280 through the smoke outlet 214 on the periphery of the first outer frame 211 in the second rotating box 220. The smoke in this cavity passes through the smoke outlet 214 on the periphery of the second rotating box 220, gradually gathers to the guide opening 286 in the middle of the disc plate 283 in the supporting guide assembly 280, and enters the cavity between the supporting guide assembly 280 and the first rotating box 210. Then, the smoke gradually diffuses from the middle to the smoke outlet 214 on the periphery of the first rotating box 210 and is discharged, and finally discharged to the outside through the smoke outlet pipe 130. The high-temperature flue gas entering the outer box shell 110 passes through the smoke vent 214 in the second rotating box box 220, the guide port 286 in the support guide assembly 280 and the smoke vent 214 in the first rotating box box 210 respectively. The hot flue gas will not only flow along the top of the outer box shell 110 along the inner wall area, that is, the flow direction of the flue gas changes from diffusion to concentration, and then from concentration to diffusion. The dispersed high-temperature flue gas cooperates with the heat conducting plate 240 outside the rotating heat conducting pipe 230, so that the heat conducting plate 240 has a better heat conducting effect, that is, it can further improve the device's efficiency in absorbing heat from the high-temperature flue gas.

[0040] The socket 284 is used to penetrate and install the heat pipe 230 , and the positioning groove 285 is used to penetrate and install the heat conducting plate 240 .

[0041] In the above-mentioned modified nitrile rubber vulcanization furnace high-temperature exhaust gas waste heat recovery device, when the high-temperature flue gas enters the cavity enclosed by the second rotating box 220 and the outer box shell 110 through the smoke inlet pipe 120, it is not possible to well disperse the high-temperature flue gas and let it enter from different smoke outlets 214 on the periphery of the second rotating box 220, and simultaneously capture and collect the ash in the flue gas.

[0042] See also Figure 2 , Fig. 9 and Fig.10 The device for recovering waste heat from high-temperature exhaust gas of a modified nitrile rubber vulcanization furnace further includes a heat-conducting part 40 for capturing ash. A plurality of heat-conducting parts 40 for capturing ash are arranged in a ring array outside the outlet pipe 260. The heat-conducting part 40 for capturing ash includes a collecting box 410, a heat-conducting frame plate 420 and an ear plate 430. A cavity 440 is arranged inside the heat-conducting frame plate 420. One end of the heat-conducting frame plate 420 is connected to the outer wall of the outlet pipe 260. The other end of the heat-conducting frame plate 420 is detachably connected and installed with the collecting box 410 through an ear plate 430 and a bolt. A plurality of first capturing holes 450 and second capturing holes 460 are respectively arranged on both sides of the heat-conducting frame plate 420. The first capturing holes 450 and the second capturing holes 460 are arranged in a staggered arrangement.

[0043] While the rotating driving assembly 270 drives the first rotating box 210 and the second rotating box 220 to rotate, it also drives the liquid outlet pipe 260 on one side of the second rotating box 220 to rotate. The rotating liquid outlet pipe 260 drives the external heat-conducting frame 420 and the collecting box 410 to rotate. The rotating heat-conducting frame 420 can disperse the high-temperature flue gas entering from the smoke inlet pipe 120, that is, the high-temperature flue gas entering the outer box shell 110 from the smoke inlet pipe 120 is quickly dispersed to the smoke outlet 214 at different positions of the inner wall of the outer box shell 110 near the second rotating box 220 and simultaneously enters the cavity between the side support guide assembly 280 and the second rotating box 220.

[0044] When the heat-conducting frame plate 420 rotates and contacts the heat in the flue gas, the heat in the flue gas will also be conducted to the inside of the liquid outlet pipe 260 through the heat-conducting frame plate 420, that is, the flow regulating part 30 has the function of assisting heat conduction. And when the heat-conducting frame plate 420 rotates forward or reverse, the rotating heat-conducting frame plate 420 can capture dust in the flue gas into the cavity 440 through the first capture hole 450 or the second capture hole 460, and the dust is thrown into the collection box 410 through the cavity 440 under the action of centrifugal force to complete the collection. The staggered first capture hole 450 and the second capture hole 460 prevent the captured dust from being directly discharged through the small hole on the other side, thereby improving the capture efficiency of the small hole, and the excess gas can be discharged from the small hole on the other side.
