Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, and in particular to a double heat storage heat exchange component and a temperature control strategy thereof. Background Art

[0002] Heat exchange is the process of heat transfer between two objects or parts of the same object caused by temperature difference. Heat exchange is generally completed through three methods: heat conduction, heat convection and heat radiation. When objects with different temperatures come into contact with each other, the high-temperature object releases heat to the low-temperature object, and the low-temperature object absorbs heat from the high-temperature object. When thermal equilibrium is reached, the heat exchange of the objects reaches equilibrium.

[0003] Thermal storage refers to the process in which a substance absorbs heat and can store it, and release it when needed. Thermal storage combustion technology is often arranged as single thermal storage or double thermal storage according to the different properties of the fuel. Single thermal storage refers to the thermal storage of only the combustion air or fuel medium involved in thermal storage combustion; double thermal storage generally refers to the preheating of both the fuel and the combustion air. During the combustion process, the furnace body requires a large amount of fuel gas and also emits a large amount of exhaust gas, and there is a lot of waste heat in the exhaust gas.

[0014] A dual heat storage heat exchange temperature control strategy includes the following steps:

[0015] First, the left and right air outlet pipes are respectively connected to the left and right sides of the furnace body. One air outlet pipe sprays out gas, and the other air outlet pipe absorbs smoke. The material pipe is used to let the external gas enter the inside of the reversing pipe. The smoke exhaust pipe is connected to the smoking equipment, and cooperates with the air outlet pipe to absorb the smoke inside the furnace body. The temperature sensor is used to detect the temperature of the smoke inside the air outlet pipe. When the temperature reaches the specified value, the rotation of the steering plate is controlled to close or open the channels between the reversing pipe and the left and right air inlet pipes. When the pipe mouth of the left air outlet pipe burns gas, the right air outlet pipe serves as a smoke exhaust port, and the tail gas stores heat in the right heat storage body; when the pipe mouth of the right air outlet pipe burns gas, the left air outlet pipe serves as a smoke exhaust port, and the tail gas stores heat in the left heat storage body, realizing double heat storage heat exchange.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The device can realize the alternating flow of coal gas in the left and right outlet pipes by adjusting the rotation of the steering plate, and further adjust the alternating combustion of the left and right outlet pipes. When one outlet pipe burns gas, the other outlet pipe discharges flue gas. At the same time, the heat storage body on this side is used to store heat from the exhaust gas, and the temperature of the flue gas inside the outlet pipe is detected by the temperature sensor. The back and forth rotation of the steering plate is further controlled to realize the alternating heat storage and heat release of the left and right heat storage bodies. When the furnace body discharges exhaust gas, it can effectively cooperate with the temperature sensor to detect the temperature of the flue gas, further control the heat storage and heat release of the heat storage body, and achieve energy-saving effect, avoiding the situation where the heat in the exhaust gas is not reasonably utilized during the exhaust gas discharge process of the furnace body, thereby wasting waste heat.

[0018] (2) When the heat storage body absorbs the residual heat of the flue gas, the granular impurities in the flue gas will remain inside the through-holes of the honeycomb heat storage body. The electromagnet pushes the square block to move, which can make the stamping plate squeeze the gas inside the stamping box. The squeezed gas enters the through-holes of the heat storage body, which can clean up the granular impurities attached to the inside of the heat storage body, avoiding the problem that the heat storage body is blocked by impurities and affecting the circulation of the flue gas, resulting in the problem that the flue gas cannot be discharged. At the same time, cleaning the through-holes of the heat storage body can solve the problem that the heat storage effect of the heat storage body is deteriorated due to the blockage of impurities.

[0019] (3) The limiting effect of the sleeve on the inner wall of the heat storage body can prevent the heat storage body from sliding when the staff quickly moves the heat storage body to the cleaning parts, so that the heat storage body can fall accurately under the stamping box, which is convenient for the gas inside the stamping box to enter the interior of the heat storage body. The gas will not escape to the outside due to the misalignment between the upper surface of the heat storage body and the lower surface of the stamping box, resulting in the problem that the gas cannot effectively enter the through hole of the heat storage body, resulting in the gas being unable to blow off the impurities inside the through hole of the heat storage body.

[0020] (4) The adsorption effect of the stamping box on the impurity particles on the surface of the heat storage body can prevent the accumulation of impurities on the surface of the stamping box and thus affect the circulation of flue gas and coal gas; at the same time, the cleaning effect of the scraper and the stamping plate on the bottom of the stamping box can prevent the impurities at the bottom of the stamping box from falling onto the surface of the heat storage body and the inside of the through hole when the stamping box cleans the heat storage body next time, causing the problem of the heat storage being affected by the particulate impurities inside the heat storage body.

[0021] (5) When the heat storage body is damaged and needs to be removed and replaced, the staff can manually drag the circular plate downward to move the ring out from the inner wall of the heat storage body. At the same time, through the cooperation between the magnetic block and the magnetic plate, the rubber rod can push the magnetic plate to push the heat storage body out from the upper surface of the circular plate, making it easier for the staff to remove it. This avoids the problem that the heat storage body needs maintenance inside the air outlet pipe due to long-term work, and the disassembly and removal operations are more cumbersome during maintenance work.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0035] For the first embodiment, please refer to Figure 1-Figure 6 The present invention is a dual heat storage heat exchange assembly, comprising a smoke exhaust pipe 1, a regulating mechanism 2 is fixedly connected to the upper surface of the smoke exhaust pipe 1, a cleaning component 3 is fixedly connected to the outer surface of the regulating mechanism 2; a smoking device 4 is fixedly connected to one end of the smoke exhaust pipe 1 away from the regulating mechanism 2;

[0036] The smoke exhaust pipe 1 can be used to connect to an external smoking device 4 to absorb smoke.

[0037] The control mechanism 2 includes a motor 21, the output end of the motor 21 is fixedly connected to a rotating shaft 22, the outer surface of the rotating shaft 22 is fixedly connected to a steering plate 23, the outer surface of the steering plate 23 is rotatably connected to a reversing tube 24, the upper surface of the reversing tube 24 is fixedly connected to a feed pipe 25, both sides of the reversing tube 24 are fixedly connected to an air inlet pipe 26, the upper end of the air inlet pipe 26 is fixedly connected to a disassembly component 27, the side of the disassembly component 27 close to the motor 21 is fixedly connected to a temperature sensor 28, and the upper surface of the disassembly component 27 is provided with an outlet pipe 29. The feed pipe 25 is used to enter the external fuel gas or coal gas, and the outlet pipes 29 located on the left and right sides are used to connect the furnace body. The motor 21 can drive the steering plate 23 to rotate on the inner wall of the reversing tube 24 through the rotating shaft 22, and the rotation of the steering plate 23 can regulate the gas flow direction between the feed pipe 25 and the air inlet pipes 26 on the left and right sides.

[0038] The end of the rotating shaft 22 away from the motor 21 is rotatably connected to the inner wall of the reversing tube 24, the bottom of the reversing tube 24 is fixedly connected to the upper end of the smoke exhaust pipe 1, and the side of the reversing tube 24 close to the motor 21 is fixedly connected to the lower surface of the motor 21 through a support seat.

[0039] The smoke exhaust pipe 1 is connected to the external smoking device 4 to absorb smoke. The left and right air outlet pipes 29 are connected to the furnace body in the middle, and the feed pipe 25 is used to pass coal gas or fuel gas into the furnace body to facilitate combustion inside the furnace body. The control mechanism 2 controls whether the coal gas enters the left air inlet pipe 26 or the right air inlet pipe 26 by rotating the steering plate 23. After the fuel gas enters the air inlet pipe 26, it will enter the inside of the reversing pipe 24, and then continue to enter the inside of the air inlet pipe 26, and flow through the inside of the disassembly component 27 to the upper air outlet pipe 29, and then enter the inside of the furnace body to achieve combustion.

[0040] When in use, after the coal gas enters the feed pipe 25, according to the position of the deflection plate 23, the coal gas enters any one of the inlet pipes 26 on the left and right sides, and flows through the interior of the disassembly component 27 to the outlet pipe 29 above, and then enters the interior of the furnace body to achieve combustion. The outlet pipe 29 on the other side cannot enter the coal gas, so it is used to cooperate with the smoke exhaust pipe 1 to collect the smoke inside the furnace body. The temperature sensor 28 located on the surface of the disassembly component 27 detects the temperature of the smoke inside the disassembly component 27. When the temperature reaches a specified value, the motor 21 drives the rotation of the shaft 22 and the deflection plate 23. The rotating plate can rotate along the inside of the reversing tube 24, so that the deflection plate 23 changes the flow direction of the gas, blocks the previous passage between the inlet pipe 26 and the feed pipe 25, so that the gas cannot flow into the previous inlet pipe 26, and the passage between the other inlet pipe 26 and the feed pipe 25 is opened. That is, the left and right inlet pipes 26 and outlet pipes 29 alternately realize the circulation of gas and smoke.

[0041] The disassembly component 27 includes a push plate 271, a sliding rod 272 is fixedly connected to the side of the push plate 271 close to the cleaning component 3, a surrounding shell 273 is slidably connected to the outer surface of the sliding rod 272, a U-shaped frame 274 is fixedly connected to the side of the surrounding shell 273 away from the push plate 271, a circular plate 275 is slidably connected to the upper surface of the U-shaped frame 274, a semicircular plate 276 is fixedly connected to the upper surface of the circular plate 275, a heat storage body 277 is provided on the inner wall of the semicircular plate 276, and a limiting component 278 is fixedly connected to the outer surface of the semicircular plate 276. The push plate 271 can drive the sliding rod 272 and the circular plate 275 to slide, the U-shaped frame 274 provides support for the sliding of the circular plate 275, and the surrounding shell 273 can be combined with the semicircular plate 276 on the upper surface of the circular plate 275, or can be separated. The slide bar 272 can slide along the inner wall of the surrounding shell 273. The heat storage body 277 is a honeycomb heat storage body 277, which can play the role of heat storage and heat release.

[0042] The upper surface of the surrounding shell 273 is fixedly connected to the lower end of the air outlet pipe 29 , the lower end of the surrounding shell 273 is fixedly connected to the upper end of the air inlet pipe 26 , and the end of the sliding rod 272 away from the push plate 271 is fixedly connected to the side of the annular plate 275 close to the surrounding shell 273 .

[0043] When in use, when the left outlet pipe 29 sprays gas to achieve combustion, the left heat storage body 277 releases heat to heat the gas, the right outlet pipe 29 cooperates with the smoke exhaust pipe 1 to achieve smoke exhaust, and the heat storage body 277 between the surrounding shell 273 and the semicircular plate 276 absorbs the heat of the smoke; when the right outlet pipe 29 sprays gas to achieve combustion, the right heat storage body 277 releases heat to heat the gas, the left outlet pipe 29 cooperates with the smoke exhaust pipe 1 to achieve smoke exhaust, and the heat storage body 277 between the surrounding shell 273 and the semicircular plate 276 absorbs the heat of the smoke. That is, the left and right outlet pipes 29 burn alternately and store heat alternately, and the temperature of the heat storage body 277 in the smoke circulation is detected by the temperature sensor 28. When the smoke temperature reaches a certain value, it automatically switches alternately.

[0044] When the furnace is not working, the through holes inside the heat storage body 277 may be blocked due to the flow of particulate impurities inside the flue gas. Figure 4As shown, the push plate 271 can be used to push the sliding rod 272 and the circular plate 275 and the semicircular plate 276 to move. The circular plate 275 can slide along the upper surface of the U-shaped frame 274, and the upper surface of the circular plate 275 also has a heat storage body 277. The semicircular plate 276 and the surrounding shell 273 can be separated by the sliding of the circular plate 275, and the heat storage body 277 can also be separated from the inner wall of the surrounding shell 273. When the heat storage body 277 moves to one side of the cleaning component 3, the inside of the heat storage body 277 is cleaned by the cleaning component 3. The limiting component 278 can limit the position of the heat storage body 277 to prevent the heat storage body 277 from being offset during the movement, or from being inaccurate when reaching the specified position, resulting in the problem that the cleaning effect of the cleaning component 3 on the inside is poor.

[0045] When the interior of the heat storage body 277 is cleaned, pull the push plate 271 and drive the slide rod 272 and the annular plate 275 and the semicircular plate 276 to reset until the surrounding shell 273 fits with the annular plate 275 and the surrounding shell 273 fits with the semicircular plate 276 again, wrapping the heat storage body 277 inside the two to achieve sealing of the heat storage body 277, and the heat storage body 277 can continue to work.

[0046] The limiting component 278 includes a ring 2781, both sides of the ring 2781 are fixedly connected with a fixing plate 2782, the upper surface of the fixing plate 2782 is fixedly connected with a connecting spring 2783, the upper surface of the fixing plate 2782 is fixedly connected with a magnet 2784, the upper surface of the magnet 2784 is movably connected with a magnetic plate 2785, the inner wall of the magnetic plate 2785 is rotatably connected with a swing shaft 2786, the side of the magnetic plate 2785 away from the fixing plate 2782 is fixedly connected with a rubber rod 2787, and the end of the rubber rod 2787 away from the magnetic plate 2785 is fixedly connected with an electromagnet 2788. The collar 2781 serves to limit the inner wall of the heat storage body 277. The fixed plate 2782 can drive the collar 2781 to move downward. The fixed plate 2782 slides against the inner wall of the circular plate 275 during the downward movement and can be out of contact with the inner wall of the heat storage body 277. The fixed plate 2782 can also drive the movement of the magnetic block 2784. The magnetic block 2784 and the magnetic plate 2785 are attracted to each other and can attract the magnetic plate 2785 to rotate around the swing shaft 2786.

[0047] Both sides of the fixed plate 2782 are slidably connected to the inner wall of the circular plate 275, the top of the connecting spring 2783 is fixedly connected to the inner wall of the circular plate 275, the magnetic block 2784 is slidably connected to the inner wall of the circular plate 275, both ends of the swing shaft 2786 are fixedly connected to the inner wall of the circular plate 275, and the side of the electromagnet 2788 close to the swing shaft 2786 is fixedly connected to the side of the circular plate 275 away from the ring 2781.

[0048] During use, when the heat storage body 277 is damaged and needs to be replaced, the heat storage body 277 has been separated from the surrounding shell 273, but has not been moved to the designated cleaning position. The staff pulls the collar 2781 and the fixing plate 2782 downward for a certain distance with one hand, which will stretch the connecting spring 2783 until the collar 2781 completely leaves the inner wall of the middle part of the heat storage body 277. At the same time, the magnetic block 2784 will also be driven to move downward during the downward movement of the fixed plate 2782. When the magnetic block 2784 is out of contact with the magnetic plate 2785, the magnetic plate 2785 contacts the rubber rod 2787 on one side, and rotates around the swing shaft 2786 toward the side close to the ring 2781 under the elasticity of the rubber rod 2787. That is, the upper part of the magnetic plate 2785 will rotate toward the inner wall of the semicircular plate 276, and squeeze the middle position of the heat storage body 277 inside, pushing the heat storage body 277 to slide along the side away from the semicircular plate 276, so that the heat storage body 277 can slide out automatically, and the staff can take the heat storage body 277 out from the surface of the circular plate 275 with the other hand, so as to facilitate the replacement of the new heat storage body 277.

[0049] After the heat storage body 277 is taken, the staff puts down the fixing plate 2782, and the fixing plate 2782 and the collar 2781 are reset under the elasticity of the connecting spring 2783. When the magnetic block 2784 is also quickly reset under the upward movement of the fixing plate 2782, the inclined surface of the lower part of the magnetic plate 2785 close to the magnetic block 2784 will be adsorbed by the inclined surface of the magnetic block 2784 and fit together. Since the parts where the magnetic block 2784 and the magnetic plate 2785 contact are all inclined surfaces, the inclined surface of the magnetic plate 2785 can be limited to a certain extent, so that the magnetic plate 2785 is only in a vertical position, and cannot continue to rotate to the side of the collar 2781 around the swing shaft 2786. After the magnetic block 2784 and the magnetic plate 2785 are adsorbed, the new heat storage body 277 is inserted from top to bottom into the inside of the collar 2781 to achieve the limit and placement of the heat storage body 277. Afterwards, the push plate 271 is moved to make the surrounding shell 273 fit with the annular plate 275, and the new heat storage body 277 can also be driven to fit with the surrounding shell 273, so that the whole device can realize heat exchange work again.

The cleaning plate 31 is arranged directly below the punching box 36. When the telescopic rod 34 is activated, the short block 35 and the punching box 36 can be driven to move downward. The punching plate 38 can slide downward along the inner wall of the punching box 36. The limiting ring 301 has a limiting effect on the fixing rod 39. The pull rope 303 can pull the fixing rod 39 to slide upward along the inner wall of the L-shaped tube 302. The square block 304 and the electromagnet 2788 are both made of magnetic materials and have strong repulsion.

[0051] The collecting component 37 includes a collecting box 371, the inner wall of the collecting box 371 is rotatably connected to a screw rod 372, one end of the screw rod 372 away from the collecting box 371 is fixedly connected to a roller 373, the outer surface of the screw rod 372 is threadedly connected to a scraper 374, and the bottom of the scraper 374 is fixedly connected to a collecting plate 375. The roller 373 can roll along the outer surface of the supporting box 33 and further drive the screw rod 372 to rotate, and the screw rod 372 can drive the scraper 374 and the collecting plate 375 to move during the rotation process.

[0052] The side of the cleaning plate 31 close to the surrounding shell 273 is fixedly connected to the outer surface of the air inlet pipe 26, the end of the L-shaped tube 302 away from the fixed rod 39 is fixedly connected to the upper surface of the support box 33, the end of the pull rope 303 away from the square block 304 is fixedly connected to the top of the fixed rod 39, the square block 304 is slidingly connected to the inner wall of the support box 33, and the roller 373 is rollingly connected to both sides of the support box 33.

[0053] When in use, when the heat storage body 277 moves to the bottom of the stamping box 36 in the cleaning component 3 during the movement of the circular plate 275, the electromagnet 2788 located on one side of the semicircular plate 276 moves just below the square block 304. At this time, the electromagnet 2788 is energized, and the square block 304 slides upward along the inner wall of the support box 33 due to the repulsive force of the electromagnet 2788. During the sliding process of the square block 304, the end of the pull rope 303 away from the square block 304 will be under the gravity of the stamping plate 38. The punching plate 38 slides along the inner wall of the L-shaped tube 302 toward the side close to the fixed rod 39, and the fixed rod 39 and the punching plate 38 slide inward toward the inner wall of the punching box 36 due to the sliding of the pull rope 303. In the process of the punching plate 38 sliding inward along the inner wall of the punching box 36, the gas inside the punching box 36 is squeezed, so that the gas inside the punching box 36 is sprayed into the through hole of the heat storage body 277 through the through hole at the bottom of the inner wall. The bottom of the punching box 36 is very close to the upper surface of the heat storage body 277. Therefore, the punching effect of the punching plate 38 on the inside of the punching box 36 can flush out all the impurities attached to the inside of the through hole of the heat storage body 277, avoiding the problem of excessive attachment of impurities inside the through hole of the heat storage body 277, causing the through hole to be blocked. The cleaned impurities will fall into the cleaning plate 31 below to be collected and processed.

[0054] After the through hole inside the heat storage body 277 is cleaned, the electromagnet 2788 loses power, and the square block 304 located above the electromagnet 2788 cannot feel the repulsive force and will slide downward along the inner wall of the support box 33, pulling the pull rope 303 to slide, and the pull rope 303 will pull the fixed rod 39 and the stamping plate 38 upward, because the surface of the fixed rod 39 is fixedly connected to the limit ring 301, when the upper surface of the limit ring 301 contacts the port of the L-shaped tube 302, the limit tube and the fixed rod 39 are stuck, and the stamping plate 38 can no longer move up, so the square block 304 will not continue to slide down. During the process of the stamping plate 38 being reset upward, the stamping plate 38 can absorb air from the outside at the bottom of the stamping box 36, and there may still be some granular impurities on the upper surface of the heat storage body 277. The granular impurities on the upper surface of the heat storage body 277 are adsorbed by the stamping plate 38. At this time, some of the granular impurities are sucked to the bottom of the stamping box 36. Due to the small through hole at the bottom of the stamping box 36, they cannot enter the interior of the stamping box 36.

[0055] When some impurities are adsorbed on the bottom of the punch box 36, the circular plate 275 and the heat storage body 277 are reset by moving the push plate 271 and the slide bar 272. At this time, there is no heat storage body 277 below the punch box 36. The contraction of the telescopic rod 34 can drive the short block 35 and the punch box 36 to move slowly upward, and the pressing plate 38 can squeeze the inside of the punch box 36 to blow down some of the impurities trapped in the hole and drop them to the surface of the cleaning plate 31 below, and the punch box 36 can drive the collection box 371, the screw rod 372 and the roller 373 to move upward. The roller 373 will rotate along the inner wall of the support box 33 during the upward movement. Therefore, the screw rod 372 can drive the scrapers 374 on both sides of the punch box 36 and the collection plate 375 to move toward each other during the rotation, and the impurities attached to the bottom side of the punch box 36 are scraped off by the scrapers 374, and the scraped impurities will fall into the inside of the collection plate 375 to achieve collection. When the impurities are collected, the telescopic rod 34 is retracted again and drives the punch box 36 to reset.

[0056] The specific workflow is as follows:

[0057] First, when the left outlet pipe 29 sprays out gas to achieve combustion, the left heat storage body 277 releases heat to heat the gas, the right outlet pipe 29 cooperates with the smoke exhaust pipe 1 to achieve smoke exhaust, and the heat storage body 277 between the surrounding shell 273 and the semicircular plate 276 absorbs the heat of the smoke; when the right outlet pipe 29 sprays out gas to achieve combustion, the right heat storage body 277 releases heat to heat the gas, the left outlet pipe 29 cooperates with the smoke exhaust pipe 1 to achieve smoke exhaust, and the heat storage body 277 between the surrounding shell 273 and the semicircular plate 276 absorbs the heat of the smoke. That is, the left and right outlet pipes 29 burn alternately and store heat alternately, and the temperature of the heat storage body 277 in the smoke circulation is detected by the temperature sensor 28. When the smoke temperature reaches a certain value, it automatically switches alternately.

[0058] When the furnace body is not working and the heat storage capacity of the heat storage body 277 is reduced due to blockage of the through hole, the heat storage body 277 on the annular plate 275 is moved to the side of the cleaning component 3 by moving the push plate 271 and the slide rod 272. The stamping plate 38 squeezes the gas inside the stamping box 36 through the cooperation of the electromagnet 2788 and the square block 304, so that the impurities inside the through hole of the heat storage body 277 can be cleaned out.

[0059] When the stamping plate 38 is reset upward along the inner wall of the stamping box 36, the impurities attached to the upper surface of the heat storage body 277 can be adsorbed, and the impurities attached to the bottom of the stamping box 36 can be cleaned by coordinating the subsequent upward movement of the stamping box 36 and the movement of the scraper 374.

[0060] When the heat storage body 277 is damaged after working for a long time and needs to be replaced, the circular plate 275 is pulled downward to make the ring 2781 separate from the inner wall of the heat storage body 277, and cooperate with the movement of the rubber rod 2787 and the magnetic block 2784 so that the magnetic block 2784 can push the heat storage body 277 to automatically separate from the semicircular plate 276, making it easier for the staff to take it.
