Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas cooling technology, specifically a flue gas cooling device for incineration. Background Technology

[0002] The exhaust gas produced by high-temperature incineration can reach temperatures of hundreds or even thousands of degrees Celsius. If such high-temperature exhaust gas is directly emitted, it may not only damage subsequent treatment equipment, such as corroding pipes and shortening the service life of equipment, but also pose safety hazards, such as causing fires or explosions. The device uses specific cooling technology to control the exhaust gas temperature within a reasonable range, creating favorable conditions for subsequent purification treatment, ensuring that the exhaust gas can meet emission standards, and at the same time ensuring the safe and stable operation of the entire incineration system, reducing adverse impacts on the environment and equipment.

[0003] The flue gas cooling device uses a spray condensation system. During operation, the sprayed water rapidly vaporizes upon contact with the high-temperature exhaust gas, generating a large amount of steam. This steam accumulates within the flue and, due to its inherent characteristics, does not easily flow and diffuse, forming a localized barrier layer inside the flue. Subsequent sprayed water cannot fully contact the high-temperature exhaust gas, resulting in insufficient heat exchange and weakening the cooling effect of the water. Furthermore, the device uses only a single fan, which is insufficient to meet the demand for efficient air circulation within the flue. Poor air circulation causes the high-temperature exhaust gas to remain in the flue for too long, preventing heat from being carried away in time, and the steam cannot be quickly discharged. This further hinders the water vaporization and heat absorption process and the heat exchange between the exhaust gas and the outside environment. These two factors combined make it difficult for the cooling device to quickly and effectively reduce the exhaust gas temperature, resulting in low cooling efficiency. Therefore, this application proposes a flue gas cooling device for incineration. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a flue gas cooling device, which effectively solves the problem of low cooling efficiency of flue gas cooling devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flue gas cooling device, comprising a combustion chamber and a cooling mechanism, wherein a dust removal box is installed on one side of the combustion chamber; the cooling mechanism includes a flue pipe fixedly installed on the combustion chamber and the dust removal box, the flue pipe being located between the combustion chamber and the dust removal box, a sponge fixedly connected to the flue pipe being sleeved on the flue pipe, an installation frame fixedly installed on the combustion chamber, the flue pipe being located within the installation frame, a fixed frame being installed above the installation frame, the fixed frame having two through slots, a limiting plate slidably connected within the through slots and slidingly abutting against the inner wall of the through slots, multiple nozzles fixedly installed on the limiting plates opposite to the sponge, a transmission component capable of moving the limiting plate being installed on the fixed frame, a water outlet component fixedly connected to the limiting plate being fixedly installed on the installation frame, and two oppositely arranged connecting components being installed on the installation frame, with fans opposite to the flue pipe being installed on the connecting components.

[0006] Preferably, the mounting frame is provided with two through slots that are opposite to the through slot, and the limiting plate slides against the inner wall of the through slot.

[0007] Preferably, the transmission component includes a motor fixedly mounted on a fixed frame, with the output end of the motor passing through the fixed frame and rotatably connected to it.

[0008] Preferably, a rotating rod is installed inside the fixed frame, and reciprocating screws are fixedly installed on both sides of the rotating rod. The reciprocating screws pass through the limiting plate and are threadedly connected to it. The output end of the motor is fixedly connected to one of the reciprocating screws.

[0009] Preferably, a plurality of fixing posts are fixedly installed on the upper end of the mounting frame, and the plurality of fixing posts are fixedly connected to the bottom of the mounting frame.

[0010] Preferably, the water outlet component includes a water tank fixedly installed on a fixed frame, a water outlet pipe fixedly installed at the water outlet end of the water tank, a water pump fixedly installed on the mounting frame, the water outlet pipe fixedly connected to the water inlet end of the water pump, a T-shaped water pipe fixedly installed at the water outlet end of the water pump, flexible hoses fixedly installed at both ends of the T-shaped water pipe that penetrate the mounting frame, the flexible hoses fixedly connected to a limiting plate, and a through-hole fixedly installed on the mounting frame that penetrates the mounting frame, with a water pipe fixedly installed on the through-hole that is fixedly connected to the water inlet end of the water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a cooling mechanism, the water outlet, limiting plate and sponge are coordinated to allow water to be in full and long-term contact with the flue, thereby enabling heat exchange between the water and the flue. The motor drives the reciprocating screw to rotate, which in turn drives the two limiting plates to move back and forth, squeezing out the hot water from the sponge. The nozzle sprays new cold water into the sponge to continue cooling the exhaust gas in the flue. The squeezed-out hot water flows into the water tank through the water pipe for recooling, completing the water recycling and reducing water waste. At the same time, the coordination between the two fans increases the air circulation speed, avoids heat accumulation, and improves the efficiency of the cooling work. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-6 The present invention includes an incinerator 1 and a cooling mechanism. A dust collector 2 is installed on one side of the incinerator 1. The cooling mechanism includes a flue 6 fixedly installed on the incinerator 1 and the dust collector 2. The flue 6 is located between the incinerator 1 and the dust collector 2. A sponge 12 fixedly connected to the flue 6 is sleeved on the flue 6. An installation frame 3 is fixedly installed on the incinerator 1, and the flue 6 is located inside the installation frame 3.

[0024] A fixing frame 4 is installed above the mounting frame 3. Multiple fixing posts 17 are fixedly installed at the upper end of the mounting frame 3. The multiple fixing posts 17 are fixedly connected to the bottom of the fixing frame 4. The fixing frame 4 is provided with two through slots 18. A limiting plate 13 is slidably connected in the through slots 18 and slides against the inner wall of the through slots 18. A pipe fixedly connected to the hose 22 is installed in the limiting plate 13. The pipe is fixedly connected to the nozzle 15. The mounting frame 3 is provided with two through slots 16 opposite to the through slots 18. The limiting plate 13 slides against the inner wall of the through slots 16. Multiple nozzles 15 opposite to the sponge 12 are fixedly installed on the limiting plate 13.

[0025] When in operation, the water pump 9, motor 14 and fan 11 are turned on. The water pump 9 will drive the water in the water tank 7 into the water outlet pipe 8. The water will enter the water pump 9 from the water outlet pipe 8. The water will enter the T-shaped water pipe 10 from the water outlet end of the water pump 9. Then the water will enter the hoses 22 at both ends from the T-shaped water pipe 10. Then the water will enter the pipe in the limiting plate 13 from the hoses 22. The water will enter the nozzle 15 from the pipe in the limiting plate 13. Finally, the water will be sprayed onto the sponge 12 from the nozzle 15. The water will adhere to the sponge 12 to cool the exhaust gas in the flue pipe 6.

[0026] The output of motor 14 drives one of the reciprocating screws 23 to rotate, which in turn drives the rotating rod 24 to rotate, which in turn drives the other reciprocating screw 23 to rotate. Both limiting plates 13 have threaded grooves with opposite thread directions. The reciprocating screws 23 are threaded into the grooves, and the limiting plates 13 slide against the through groove 18 and cannot move. The two reciprocating screws 23 drive the two non-rotating limiting plates 13 to move relative to each other. This relative movement of the two limiting plates 13 compresses the sponge 12, thus compressing the sponge 12. The water in the 2nd section is squeezed out to prevent the water in the sponge 12 from absorbing heat from the exhaust gas and reducing its heat dissipation efficiency. The heated water flows from the opening 19 at the bottom of the mounting frame 3 into the water pipe 5, and finally into the water tank 7. The water tank 7 is equipped with a chiller, which can cool the hot water again, thus recycling the water. At the same time, the fans 11 on both sides of the sponge 12 rotate and drive the air in the mounting frame 3 to flow rapidly. The water in the sponge 12 and the air flow driven by the fans 11 work together to form a dual cooling effect of water cooling and air cooling, which improves the cooling efficiency of the flue 6.

[0027] A transmission component capable of moving the limiting plate 13 is installed on the fixed frame 4. The transmission component includes a motor 14 fixedly installed on the fixed frame 4. The output end of the motor 14 passes through the fixed frame 4 and is rotatably connected to it. A rotating rod 24 is installed inside the fixed frame 4. Reciprocating screws 23 are fixedly installed on both sides of the rotating rod 24. The reciprocating screws 23 pass through the limiting plate 13 and are threadedly connected to it. The output end of the motor 14 is fixedly connected to one of the reciprocating screws 23.

[0028] A water outlet component is fixedly installed on the mounting frame 3 and fixedly connected to the limiting plate 13. The water outlet component includes a water tank 7 fixedly installed on the fixed frame 4. A water outlet pipe 8 is fixedly installed at the water outlet end of the water tank 7. A water pump 9 is fixedly installed on the mounting frame 3. The water outlet pipe 8 is fixedly connected to the water inlet end of the water pump 9. A T-shaped water pipe 10 is fixedly installed at the water outlet end of the water pump 9. Both ends of the T-shaped water pipe 10 are fixedly installed with flexible hoses 22 that penetrate the mounting frame 3. The flexible hoses 22 are fixedly connected to the limiting plate 13. A through-hole 19 is fixedly installed on the mounting frame 3. A water pipe 5 that is fixedly connected to the water inlet end of the water tank 7 is fixedly installed on the through-hole 19.

[0029] Two oppositely arranged connectors are installed on the mounting frame 3. The connectors include a through-hole 20 on the mounting frame 3, and a mounting component 21 is fixedly installed inside the through-hole 20. The mounting component 21 includes a connecting plate fixedly installed inside the through-hole 20, and a connecting post fixedly installed on the connecting plate. The connecting post is fixedly connected to the fan 11. A power supply is fixedly installed on the mounting frame 3. The fan 11 is connected to the power supply through a circuit. The mounting component 21 is fixedly connected to the fan 11. The fan 11 is installed on the connector opposite to the flue 6.

[0030] Working principle: When working, turn on the water pump 9, motor 14 and fan 11. The water pump 9 will drive the water in the water tank 7 into the outlet pipe 8. The water will enter the water pump 9 from the outlet pipe 8. The water will enter the T-shaped water pipe 10 from the outlet end of the water pump 9. Then the water will enter the hoses 22 at both ends from the T-shaped water pipe 10. Then the water will enter the pipe in the limiting plate 13 from the hoses 22. The water will enter the nozzle 15 from the pipe in the limiting plate 13. Finally, the water will be sprayed onto the sponge 12 from the nozzle 15. The water will adhere to the sponge 12 and cool the exhaust gas in the flue 6.

[0031] The output of motor 14 drives one of the reciprocating screws 23 to rotate, which in turn drives the rotating rod 24 to rotate, which in turn drives the other reciprocating screw 23 to rotate. Both limiting plates 13 have threaded grooves with opposite thread directions. The reciprocating screws 23 are threaded into the grooves, and the limiting plates 13 slide against the through groove 18 and cannot move. The two reciprocating screws 23 drive the two non-rotating limiting plates 13 to move relative to each other. This relative movement of the two limiting plates 13 compresses the sponge 12, thus compressing the sponge 12. The water in section 2 is squeezed out to prevent the water in sponge 12 from absorbing heat from the exhaust gas and becoming hotter, thus reducing the heat dissipation efficiency. The hot water flows from the opening 19 at the bottom of the mounting frame 3 into the water pipe 5, and finally into the water tank 7. The water tank 7 is equipped with a chiller, which can cool the hot water again, thereby recycling the water. At the same time, the fans 11 on both sides of the sponge 12 rotate and drive the air in the mounting frame 3 to flow rapidly. The water in the sponge 12 and the air flow driven by the fans 11 work together to form a dual cooling effect of water cooling and air cooling, which improves the cooling efficiency of the flue 6.
