Description

Technical Field

[0001] This invention belongs to the field of flue gas treatment technology, specifically a device for cooling and treating magnetized pyrolysis flue gas and its application method. Background Technology

[0002] Magnetized air pyrolysis involves adding a magnetic field to a conventional pyrolysis reaction. The magnetic field lowers the pyrolysis temperature of organic matter, and as air passes through it, the air molecules become more ordered, increasing the activation energy of oxygen molecules. Therefore, with the same amount of air introduced, air passing through the magnetic field can initiate a combustion reaction in more waste and burn for a longer period.

[0003] The flue gas after magnetization and pyrolysis needs to be cooled before being discharged.

[0004] The existing flue gas cooling method involves spraying water into the flue gas to achieve heat exchange and thus cooling. However, due to the small spray area, multiple nozzles often need to be used simultaneously, resulting in a waste of water resources. Summary of the Invention

[0005] This invention provides a cooling treatment device for magnetized pyrolysis flue gas, which addresses the deficiencies in the prior art.

[0006] This invention is achieved through the following technical solution:

[0007] A cooling device for magnetized pyrolysis flue gas includes a cooling pipe connected to a flue, a water storage tank located below the cooling pipe, and a water supply pipe connected to the water storage tank. A first vertical water outlet pipe, closed at the top, is vertically fixedly connected inside the cooling flue. The lower end of the first vertical water outlet pipe extends out of the cooling flue and into the water storage tank. A water outlet hole is opened on the right side of the first vertical water outlet pipe. One end of an intermediate pipe is rotatably connected to the water outlet hole via a sealed bearing. The other end of the intermediate pipe is vertically connected to the center of the right side of a disc. The disc has a cavity inside that communicates with the intermediate pipe. A spray hole communicating with the cavity is opened on the left side of the disc. A rotating shaft is vertically connected to the center of the left side of the disc. The device is fitted with a first fan blade; the lower end of the first vertical water outlet pipe is vertically connected to and communicates with one end of the horizontal water outlet pipe, and the other end of the horizontal water outlet pipe is vertically connected downwards to a second vertical water outlet pipe; a through hole is vertically opened in the cooling flue, and a driving rod is rotatably connected to the through hole through a bearing; the upper end of the driving rod is vertically connected to a first driven bevel gear; a first driving bevel gear meshing with the first driven bevel gear is fitted on the rotating shaft; a driven rod driven by the driving rod is arranged parallel to one side of the driving rod; the driven rod passes downwards through the horizontal water outlet pipe into the second vertical water outlet pipe and is coaxial with the second vertical water outlet pipe; an impeller fixedly fitted on the driven rod is provided inside the second vertical water outlet pipe.

[0008] In use, the magnetized flue gas is blown into the cooling pipe through the flue and flows out through the disc in sequence. As the gas flows through the cooling pipe, the fan blades rotate, driving the shaft to rotate. The shaft then drives the first bevel gear and the disc to rotate synchronously. The rotation of the first bevel gear drives the driving rod to rotate, which in turn drives the driven rod to rotate. The driven rod then drives the impeller to rotate. The impeller draws in water, which flows through the second vertical outlet pipe, the horizontal outlet pipe, and the first vertical outlet pipe into the disc cavity and is sprayed out from the spray nozzles. The rotation of the disc causes the sprayed water to spread out, increasing the heat dissipation area. This eliminates the need for multiple nozzles to effectively cool the flue gas, saving water resources. Furthermore, by utilizing the flow of the flue gas to drive water intake and disc rotation, energy is further saved to a certain extent, reducing equipment usage and the probability of damage.

[0009] Preferably, the lower part of the active rotating rod is fitted with a first driving gear, a second driving gear, and a third driving gear with gradually increasing diameters from top to bottom. The driven rotating rod is fitted with a first driven gear, a second driven gear, and a third driven gear, respectively meshing with the first, second, and third driving gears. The driven rotating rod is fixedly fitted with the inner wall of a bearing, and one end of a connecting rod is fixedly connected to the outer wall of the bearing. The other end of the connecting rod is fixedly connected to the corresponding first driven gear, second driven gear, and third driven gear. A circular hole is vertically opened at the center of each of the first, second, and third driven gears, and a sliding groove is opened on the side of the circular hole. An iron block slides within the sliding groove. The driven rotating rod is made of plastic and has an internal cavity. A first receiving unit, a second receiving unit, and a third receiving unit, respectively, corresponding to the first, second, and third driven gears and connected to the controller signal, are respectively installed within the internal cavity. A first electromagnet, controlled by the controller and laterally opposite to the corresponding iron block, is also fixedly installed within the internal cavity. A second electromagnet and a third electromagnet; a sleeve is vertically connected to the outlet end of the cooling pipe, and a movable plug is slidably sealed inside the sleeve. Mercury is placed between the movable plug and the inner wall of the sleeve. Heat-conducting fins are fixedly installed on the sleeve, inserted into the sleeve and in contact with the mercury. A moving rod is vertically connected to the top surface of the movable plug. The moving rod is made of insulating material and is vertically connected to a conductive rod. A support plate is fixedly installed on one side of the cooling flue. The support plate is sequentially fixedly connected from top to bottom to a first conductive sheet, a second conductive sheet, and a third conductive sheet that are in contact with the conductive rod. An insulating sheet is placed between the first, second, and third conductive sheets. The conductive sheets are respectively connected to a first wire, a second wire, and a third wire. A first transmitting unit, a second transmitting unit, and a third transmitting unit are respectively installed on the first, second, and third wires, which are signal-connected to the first receiving unit, the second receiving unit, and the third receiving unit. The first, second, and third wires are all connected to a main wire. The main wire is connected to one end of a power supply, and the other end of the power supply is connected to the conductive rod.The rotation of the active rotating rod drives the first, second, and third active gears synchronously. These gears, in turn, drive their corresponding driven gears to rotate. When the cooled flue gas reaches the required temperature, the mercury-supported movable plug contacts the conductive rod, activating the third conductive plate. The third transmitting unit then transmits a signal to the third receiving unit, which in turn transmits the signal to the controller. The controller energizes the first electromagnet, attracting the iron block inside the first driven gear. This causes the first driven gear to rotate the driven rotating rod. However, if the cooled flue gas temperature is still higher than the required temperature, the mercury... The silver expands and moves upward, causing the moving rod to move upward as well. This allows the conductive rod to contact the corresponding second and first conductive plates according to the temperature. Consequently, the second and first transmitting units activate individually based on the temperature, transmitting signals to the second and first receiving units, respectively. The second and first receiving units then transmit the signals to the controller, which activates the corresponding second and third electromagnets. These electromagnets attract the iron blocks on the second and third driven gears, resulting in higher temperatures, faster driven rod rotation, faster impeller rotation, and greater water absorption. This allows for more water to be sprayed out simultaneously, achieving better cooling and enabling automatic cooling.

[0010] Preferably, the cooling pipe is a Venturi tube structure, with the first fan blade located at the narrow diameter of the cooling pipe. The disc is a frustum-shaped structure, narrower on the left and wider on the right, and water spray holes are also provided on the side of the disc. The first fan blade being located at the narrow diameter of the cooling pipe can increase the fan blade rotation speed by increasing the flow rate.

[0011] Preferably, the water storage tank is divided into a sedimentation tank and a storage tank by a partition. The inlet of the sedimentation tank is opposite to the outlet of the cooling pipe. The impeller is located inside the storage tank. A through groove is provided on the partition, located in the middle of the sedimentation tank, connecting the sedimentation tank and the storage tank. A filter screen is horizontally fixed at the upper part of the sedimentation tank, and a drain pipe controlled by a valve is connected to the lower part of the sedimentation tank. After heat exchange, the water falls into the filter screen through the cooling pipe, is filtered, and then settles into the sedimentation tank. Small particles settle and are discharged through the drain pipe. The clean water enters the storage tank through the through groove, realizing water circulation and reducing resource waste.

[0012] Preferably, the partition and the water tank are provided with air inlet slots along the same transverse plane. A second driving bevel gear is sleeved on the driven rotating rod. A vertical beam is fixedly connected in the air inlet slot. A through hole is provided in the vertical beam. A horizontal shaft is rotatably connected in the through hole through a bearing. The horizontal shaft passes through the two air inlet slots and is sleeved with a second driven bevel gear that meshes with the second driving bevel gear. A second fan blade with the opposite rotation direction is sleeved on the horizontal shaft. Both sides of the sedimentation tank are fixedly provided with blower hoods covering the corresponding side air inlet slots. The blower hoods include inclined plates that slope from the outside to the inside towards the transverse center line of the air inlet slots and connecting plates that are fixedly connected to the upper and lower inclined plates. The front and rear sides of the inclined plates are respectively attached to the front and rear inner walls of the sedimentation tank. A spray groove through which the horizontal shaft passes is provided on the connecting plate. A filter screen is fixedly installed on the inclined plate and located above the horizontal shaft. The rotation of the driven rod drives the rotation of the second driving bevel gear, which in turn drives the rotation of the horizontal shaft. The rotation of the horizontal shaft drives the rotation of the second fan blade, thus the airflow enters the blower hood through the air inlet slot, the flow rate increases, and it is ejected from the spray slot, thereby further cooling the water falling from the filter screen.

[0013] Preferably, a baffle plate is fixedly installed at the center of the two blower hoods, with a horizontal axis passing through the baffle plate. The top surface of the baffle plate is a convex arc-shaped surface, and the two sides of the baffle plate are concave arc-shaped surfaces facing opposite directions. The baffle plate prevents the airflow from opposing each other, ensuring the airflow on both sides for cooling.

[0014] The beneficial effects of this invention are as follows: The use of this application can firstly utilize the flow of flue gas to drive water into the disc and spray it out. At the same time as spraying, it can drive the disc to rotate, thereby expanding the spraying area. While saving energy and water resources, it can also achieve cooling.

[0015] Secondly, while achieving cooling, it can control the impeller speed by changing the temperature, thereby spraying different amounts of water at different temperatures simultaneously. This achieves automatic cooling while preventing water waste (using only the appropriate amount of water for the specified temperature).

[0016] It can again achieve the recycling of water resources and use the kinetic energy generated by flue gas to cool the circulating water, further reducing the consumption of water resources and energy. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0025] A device suitable for cooling and treating magnetized pyrolysis flue gas, such as Figures 1-4As shown. It includes a cooling pipe 1 connected to the flue, a water storage tank located below the cooling pipe 1, and a water supply pipe connected to the water storage tank. The water supply pipe is connected to a water pipe to supply water to the water storage tank. A first vertical water outlet pipe 2, with its upper end closed, is vertically fixedly connected inside the cooling flue. The lower end of the first vertical water outlet pipe 2 extends out of the cooling flue and into the water storage tank. A water outlet hole is opened on the right side of the first vertical water outlet pipe 2. One end of an intermediate pipe 4 is rotatably connected to the water outlet hole via a sealed bearing. The other end of the intermediate pipe 4 is vertically connected to the center of the right side of a disc 5. The disc 5 has a cavity inside that communicates with the intermediate pipe 4. A spray hole communicating with the cavity is opened on the left side of the disc 5. A rotating shaft is vertically connected to the center of the left side of the disc 5, and a first... A blade 6; the lower end of the first vertical water outlet pipe 2 is vertically connected to and communicates with one end of the horizontal water outlet pipe, and the other end of the horizontal water outlet pipe is vertically connected to the second vertical water outlet pipe 3; a through hole is vertically opened in the cooling flue, and a drive rod 7 is rotatably connected to the through hole through a bearing. The upper end of the drive rod 7 is vertically connected to the first driven bevel gear 9. A first drive bevel gear 8 that meshes with the first driven bevel gear 9 is sleeved on the rotating shaft. A driven rod 10 driven by the drive rod 7 is arranged parallel to one side of the drive rod 7. The driven rod 10 passes downward through the horizontal water outlet pipe into the second vertical water outlet pipe 3 and is coaxial with the second vertical water outlet pipe 3. An impeller 11 is fixedly sleeved on the driven rod 10 inside the second vertical water outlet pipe 3.

[0026] The cooling pipe 1 has a Venturi tube structure, and the first fan blade 6 is located at the narrow diameter of the cooling pipe 1. The disc 5 has a frustum-shaped structure that is narrower on the left and wider on the right, and water spray holes are also provided on the side of the disc 5. The first fan blade 6 is located at the narrow diameter of the cooling pipe 1, and the fan blade rotation speed can be increased by increasing the flow rate.

[0027] In use, the magnetized flue gas is blown into the cooling pipe 1 through the flue, and then flows out through the disc 5. As the gas flows through the cooling pipe 1, the fan blades rotate, driving the shaft to rotate. The shaft then drives the first bevel gear and the disc 5 to rotate synchronously. The rotation of the first bevel gear drives the drive rod 7 to rotate, which in turn drives the driven rod 10 to rotate. The driven rod 10 then drives the impeller 11 to rotate. The impeller 11 draws in water, which flows through the second vertical water outlet pipe 3, the horizontal water outlet pipe, and the first vertical water outlet pipe 2, into the cavity of the disc 5, and is then sprayed out from the spray nozzles. The rotation of the disc 5 causes the sprayed water to spread, increasing the heat dissipation area. This eliminates the need for multiple nozzles to effectively cool the flue gas, saving water resources. Furthermore, by utilizing the flow of the flue gas to drive the water intake and the rotation of the disc 5, energy is further saved to a certain extent, reducing equipment usage and the probability of damage.

[0028] The lower part of the driving rod 7 is fitted with a first driving gear 12, a second driving gear 13, and a third driving gear 14, whose diameters gradually increase from top to bottom. The driven rod 10 is fitted with a first driven gear 15, a second driven gear 16, and a third driven gear 17, which mesh with the first driving gear 12, the second driving gear 13, and the third driving gear 14, respectively. The diameter of the first driving gear 12 is the same as the diameter of the first driven gear 15. The driven rod 10 is fixedly fitted with the inner wall of a bearing, and one end of a connecting rod is fixedly connected to the outer wall of the bearing. The other end of the connecting rod is respectively connected to the corresponding first driven gear. Gear 15, the second driven gear 16, and the third driven gear 17 are fixedly connected. A circular hole is vertically formed at the center of each gear. A sliding groove is formed on the side of the circular hole, and an iron block 19 slides within the groove. The driven rotating rod 10 is made of plastic and has an internal cavity. A first receiving unit, a second receiving unit, and a third receiving unit, corresponding to the first driven gear 15, the second driven gear 16, and the third driven gear 17 and connected to the controller signal, are respectively installed within the internal cavity. A device controlled by the controller is also fixedly installed within the internal cavity. A first electromagnet 18, a second electromagnet, and a third electromagnet are laterally opposite to the corresponding iron block 19; a sleeve is vertically connected to the outlet end of the cooling pipe 1, a movable plug is slidably sealed inside the sleeve, mercury is placed between the movable plug and the inner wall of the sleeve, a heat-conducting fin 23 is fixedly installed on the sleeve, the heat-conducting fin 23 is inserted into the sleeve and in contact with the mercury, a moving rod is vertically connected to the top surface of the movable plug, the moving rod is made of insulating material, a conductive rod 24 is vertically connected to the moving rod, a support plate is fixedly installed on one side of the cooling flue, and a first conductive plate 24 in contact with the conductive rod 24 is fixedly connected to the support plate from top to bottom. 5. The second conductive sheet 26 and the third conductive sheet 27 are separated by an insulating sheet. The conductive sheets are connected to the first wire, the second wire and the third wire respectively. The first wire, the second wire and the third wire are respectively provided with the first transmitting unit 20, the second transmitting unit 21 and the third transmitting unit 22, which are respectively connected to the first receiving unit, the second receiving unit and the third receiving unit. The first wire, the second wire and the third wire are all connected to the main wire. The main wire is connected to one end of the power supply and the other end of the power supply is connected to the conductive rod 24.

[0029] The rotation of the active rotating rod 7 drives the first active gear 12, the second active gear 13, and the third active gear 14 synchronously. These gears, in turn, drive the corresponding first driven gear 15, second driven gear 16, and third driven gear 17 to rotate. When the cooled flue gas temperature reaches the required level, the mercury-supported movable plug contacts the conductive rod 24, causing it to contact the third conductive plate 27. The third transmitting unit 22 is in a conductive path and transmits a signal to the third receiving unit. The receiving unit then transmits the signal to the controller. The controller energizes the first electromagnet 18, causing it to attract the iron block 19 inside the first driven gear 15. This causes the first driven gear 15 to drive the rotation of the driven rotating rod 10. However, if the cooled flue gas temperature is still higher than the required temperature... Mercury expands and moves upward, causing the moving rod to move upward as well. This causes the conductive rod 24 to contact the corresponding second conductive sheet 26 and first conductive sheet 25 according to the temperature. Consequently, the second transmitting unit 21 and the first transmitting unit 20 are activated individually according to the temperature, transmitting signals to the second receiving unit and the first receiving unit, respectively. The second receiving unit and the first receiving unit transmit the signals to the controller, which controls the activation of the corresponding second electromagnet and third electromagnet. This attracts the iron blocks 19 on the second driven gear 16 and the third driven gear 17, resulting in a higher temperature and a faster rotation speed of the driven rotating rod 10. The faster the driven rotating rod 10 rotates, the faster the impeller 11 rotates, and the more water is absorbed. This allows for more water to be sprayed out simultaneously, achieving better cooling and enabling automatic cooling.

[0030] The water storage tank is divided into a sedimentation tank 28 and a water storage tank 29 by a partition. The inlet of the sedimentation tank 28 is opposite to the outlet of the cooling pipe 1. The water supply pipe and impeller 11 are located inside the water storage tank 29. A through groove 31 is provided on the partition, located in the middle of the sedimentation tank 28. The sedimentation tank 28 and the water storage tank 29 are connected by the through groove 31. A filter screen 30 is horizontally fixed at the upper part of the sedimentation tank 28, and a drain pipe controlled by a valve is connected to the lower part of the sedimentation tank 28. The water after heat exchange falls into the filter screen 30 through the cooling pipe 1, and then settles into the sedimentation tank 28 after filtration. Small particles settle and can be discharged through the drain pipe. The clean water enters the water storage tank 29 through the through groove 31, realizing water circulation and reducing resource waste.

[0031] The partition and the water tank 29 are provided with air inlet slots along the same transverse plane. A second driving bevel gear 32 is sleeved on the driven rotating rod 10. A vertical beam is fixedly connected in the air inlet slot. A through hole is opened in the vertical beam. A horizontal shaft 37 is rotatably connected in the through hole through a bearing. The horizontal shaft 37 passes through the two air inlet slots and is sleeved with a second driven bevel gear 33 that meshes with the second driving bevel gear 32. A second fan blade 34 with the opposite rotation direction is sleeved on the horizontal shaft 37. Both sides of the sedimentation tank 28 are fixedly provided with blower hoods 35 covering the corresponding side air inlet slots. The blower hood 35 includes an inclined plate that is inclined from the outside to the inside towards the transverse center line of the air inlet slot and a connecting plate that is fixedly connected to the upper and lower inclined plates. The front and rear sides of the inclined plate are respectively attached to the front and rear inner walls of the sedimentation tank 28. A spray groove through which the horizontal shaft 37 passes is opened on the connecting plate. The filter screen 30 is fixedly installed on the inclined plate and located above the horizontal shaft 37. The rotation of the driven rod 10 drives the rotation of the second active bevel gear 32, which in turn drives the rotation of the horizontal shaft 37. The rotation of the horizontal shaft 37 drives the rotation of the second fan blade 34, thereby causing the airflow to enter the blower shroud 35 through the air inlet slot, increasing the flow rate and spraying it out from the spray slot, thus further cooling the water falling from the filter screen 30.

[0032] A baffle plate 36 is fixedly installed at the center of the two blower hoods 35. A horizontal axis 37 passes through the baffle plate 36. The top surface of the baffle plate 36 is a convex arc surface, and the two sides of the baffle plate 36 are concave arc surfaces facing opposite directions. The baffle plate 36 can prevent the airflow on both sides from colliding and ensure the airflow on both sides for cooling.

[0033] A method for cooling magnetized pyrolysis flue gas includes the following steps: (1) The magnetized flue gas is blown into the cooling pipe 1 through the flue, and flows out through the disc 5 and the heat-conducting fins 23 in sequence. In the cooling pipe 1, the fan blades rotate with the flow of gas. The rotation of the fan blades drives the rotating shaft to rotate. The rotation of the rotating shaft drives the first bevel gear and the disc 5 to rotate synchronously. The rotation of the first bevel gear drives the active rotating rod 7 to rotate. The rotation of the active rotating rod 7 drives the first active gear 12, the second active gear 13 and the third active gear 14 to rotate synchronously. The first active gear 12, the second active gear 13 and the third active gear 14 drive the corresponding first driven gear 15 and the second driven gear 16, respectively. When the third driven gear 17 rotates and the temperature reaches the required level after cooling, the mercury-supported movable plug causes the conductive rod 24 to contact the third conductive plate 27. The third transmitting unit 22 is in the pass and transmits the signal to the third receiving unit. The third receiving unit transmits the signal to the controller. The controller controls the first electromagnet 18 to be energized and attract the iron block 19 inside the first driven gear 15. Thus, the first driven gear 15 drives the driven rotating rod 10 to rotate. The rotation of the driven rotating rod 10 drives the impeller 11 to rotate. The rotation of the impeller 11 draws in water and sends it through the second vertical water outlet pipe 3, the horizontal water outlet pipe, the first vertical water outlet pipe 2, and into the cavity of the disc 5, where it is sprayed out from the spray hole. Due to the rotation of the disc 5... This causes the sprayed water to spread out, thereby cooling the hot air and increasing the heat dissipation area. The heated water then falls into the sedimentation tank 28 through the cooling pipe 1 and after sedimentation, the clear water enters the water storage tank 29 through the through channel 31 to achieve water circulation. (2) When the temperature of the cooled flue gas is still higher than the required temperature, the mercury expands and moves upward, causing the moving rod to move upward, so that the conductive rod 24 contacts the corresponding second conductive sheet 26 and first conductive sheet 25 according to the temperature. Thus, the second transmitting unit 21 and the first transmitting unit 20 are turned on individually according to the temperature, and then the signal is transmitted to the second receiving unit and the first receiving unit respectively. The second receiving unit and the first receiving unit transmit the signal to the control unit. The controller controls the opening of the corresponding second electromagnet and third electromagnet, attracting the iron block 19 on the second driven gear 16 and the iron block 19 on the third driven gear 17, so that the higher the temperature, the faster the driven rotating rod 10 rotates, the faster the impeller 11 rotates, the more water is absorbed, and more water can be sprayed out simultaneously to achieve better cooling; (3) The rotation of the driven rotating rod 10 drives the rotation of the second active bevel gear 32 and drives the rotation of the second driven bevel gear 33 through the rotation of the second active bevel gear 32, thereby driving the rotation of the horizontal shaft 37, and the rotation of the horizontal shaft 37 drives the two second fan blades 34 to rotate, thereby further cooling the water falling from the filter screen 30.

[0034] The application of this invention first utilizes the flow of flue gas to draw water into the disc 5 and spray it out. At the same time as spraying, it can drive the disc 5 to rotate, thereby expanding the spraying area and achieving cooling while saving energy and water resources.

[0035] Secondly, while achieving cooling, it can control the speed of impeller 11 to change when the temperature changes, thereby enabling different amounts of water to be sprayed synchronously at different temperatures. This achieves automatic cooling while preventing water waste (the amount of water used depends on the temperature).

[0036] It can again achieve the recycling of water resources and use the kinetic energy generated by flue gas to cool the circulating water, further reducing the consumption of water resources and energy.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

6. An application method for a magnetized pyrolysis flue gas cooling treatment device according to claim 4, characterized in that, Includes the following steps: (1) The magnetized flue gas is blown into the cooling pipe through the flue, and flows out through the disc and heat-conducting fins in sequence. In the cooling pipe, the fan blades rotate with the flow of gas. The rotation of the fan blades drives the shaft to rotate. The rotation of the shaft drives the first bevel gear and the disc to rotate synchronously. The rotation of the first bevel gear drives the drive rod to rotate. The rotation of the drive rod drives the first drive gear, the second drive gear and the third drive gear to rotate synchronously. The first drive gear, the second drive gear and the third drive gear drive the corresponding first driven gear, the second driven gear and the third driven gear to rotate respectively. After cooling When the required temperature is reached, the mercury-supported movable plug causes the conductive rod to contact the third conductive plate. The third transmitting unit is in the circuit and transmits the signal to the third receiving unit. The third receiving unit transmits the signal to the controller, which energizes the first electromagnet and attracts the iron block inside the first driven gear. This causes the first driven gear to drive the driven rod to rotate, which in turn drives the impeller to rotate. The impeller's rotation draws in water and forces it through the second vertical outlet pipe, the horizontal outlet pipe, and the first vertical outlet pipe into the disc cavity, where it is sprayed out from the spray nozzle. The rotation of the disc further disperses the sprayed water... (1) When the flue gas temperature is still higher than the required temperature, the mercury expands and moves upward, causing the moving rod to move upward, so that the conductive rod contacts the corresponding second conductive sheet and first conductive sheet according to the temperature. Thus, the second transmitting unit and the first transmitting unit are turned on individually according to the temperature, and then the signals are transmitted to the second receiving unit and the first receiving unit respectively. The second receiving unit and the first receiving unit will then transmit the signals to the second receiving unit and the first receiving unit respectively. The signal is transmitted to the controller, which controls the opening of the corresponding second electromagnet and third electromagnet, attracting the iron block on the second driven gear and the iron block on the third driven gear. As a result, the higher the temperature, the faster the driven rod rotates, the faster the impeller rotates, and the more water is absorbed, so that more water can be sprayed out simultaneously, achieving better cooling; (3) The rotation of the driven rod drives the rotation of the second active bevel gear and drives the rotation of the second driven bevel gear through the rotation of the second active bevel gear, thereby driving the rotation of the horizontal shaft. The rotation of the horizontal shaft drives the rotation of the two second fan blades, thereby further cooling the water falling from the filter screen.
