Description

Technical Field

[0001] This utility model relates to a flue gas cooling device for sludge incineration, belonging to the technical field of flue gas cooling equipment. Background Technology

[0002] Sludge drying and incineration is a sludge treatment and disposal method that has been developed in recent years. After incineration, sludge can be completely reduced in volume and rendered harmless. The flue gas after sludge drying and incineration is typically represented by processes such as waste heat recovery, electrostatic / bag filter dust removal, and wet deacidification. Since the sludge still has a comprehensive moisture content of about 40% to 65% after drying and entering the incinerator, the flue gas contains a large amount of water vapor. This water vapor is in gaseous state in the high-temperature process section at the front end.

[0003] However, the flue gas generated during the incineration process is at a high temperature, usually 800℃-1200℃. If it is not cooled in time, it will damage the subsequent dust removal equipment, desulfurization and denitrification equipment, and induced draft fans. Generally, the cooling methods for the flue gas generated by sludge incineration are simple and inefficient. There is an urgent need for a flue gas cooling device for sludge incineration to solve the above problems. Utility Model Content

This invention has a reasonable structure and good practicality. It utilizes both water-cooled walls and spraying to cool the flue gas, improving efficiency. At the same time, the device facilitates drainage and also has a certain effect on removing dust particles in the flue gas.

[0024] Please see Figures 1-7 This utility model provides a flue gas cooling device for sludge incineration, including a housing 1 and a cylinder 14. A water tank 6 and a coolant tank 5 are installed sequentially from left to right on the top of the housing 1. A first water pump 7 is installed above the water tank 6. The inlet of the first water pump 7 is connected to the inside of the water tank 6 through a hose. A first connecting pipe 8 is sealed and installed at the outlet of the first water pump 7. The first connecting pipe 8 is connected to the inside of the housing 1. A spray plate 20 is sealed and installed at the end of the first connecting pipe 8. An end cap 16 is sealed and installed on the right side of the cylinder 14. A first waterproof exhaust valve 15 is installed on the right side of the end cap 16. The air inlet of the first waterproof exhaust valve 15 is connected to the inside of the cylinder 14. A liquid storage tank 23 is provided on the right side wall of the cylinder 14. A docking hole connected to the liquid storage tank 23 is provided on the top of the cylinder 14. A drain valve 13 is installed at the bottom of the cylinder 14. The liquid inlet of the drain valve 13 is connected to the liquid storage tank 23. Multiple cylinders 14 are provided. This design solves the problem of the original device having a single flue gas cooling method and low efficiency.

[0025] In the first embodiment of this utility model: Multiple second water pumps 9 are installed above the coolant tank 5. The inlet ends of the multiple second water pumps 9 are connected to the interior of the coolant tank 5 via flexible hoses. The outlet ends of the multiple second water pumps 9 are each sealed with a second connecting pipe 10. The multiple second water pumps 9 facilitate the extraction and delivery of coolant. The multiple second connecting pipes 10 pass through the upper side wall of the housing 1 and are sealed to the docking holes above the multiple cylinders 14. The multiple cylinders 14 facilitate the dispersion of flue gas, allowing for more thorough cooling of the flue gas. An air inlet valve 4 is installed on the left side of the housing 1. The exhaust end of the air inlet valve 4 is located inside the housing 1. A multi-port pipe 19 is sealed to the exhaust end of the air inlet valve 4. The multiple cylinders 14 are sealed to the multiple output ends of the multi-port pipe 19. Multiple second exhaust valves 21 are installed on the right side of the housing 1. The air inlet ends of the multiple second exhaust valves 21 are located inside the housing 1. The multiple second exhaust valves 21 facilitate the discharge of flue gas. Two circular shafts 12 with round holes are rotatably mounted on the front and rear sides of the housing 1. Support plates 2 are mounted on the outer ends of the two circular shafts 12 with round holes. Bending plates 11 with round holes are mounted on the top of the two support plates 2. The two circular shafts 12 with round holes allow for slight adjustment of the angle of the housing 1, facilitating rapid drainage. Multiple mounting grooves 17 are provided at the lower corners of the housing 1. Hydraulic rods 18 are installed inside the multiple mounting grooves 17. A sealing plate 3 is mounted on the shaft ends of the multiple hydraulic rods 18. An inclined plate 22 is mounted on top of the sealing plate 3, facilitating the drainage of water.

[0026] As a second embodiment of this utility model: All parts of the device that penetrate the housing 1 are sealed with sealant, such as the connection between the exhaust end of the inlet valve 4 and the housing 1, the connection between the first connecting pipe 8 and the housing 1, and the connection between the multiple second connecting pipes 10 and the housing 1. In use, coolant is first added to the coolant tank 5, and water is added to the water tank 6. Then, external flue gas is introduced into the inlet end of the inlet valve 4, allowing the flue gas to enter the multi-port pipe 19. The flue gas is divided into three parts by the multi-port pipe 19 and enters the three cylinders 14. Next, the inlet valve 4 is closed, and then multiple second water pumps 9 are started to draw coolant into the multiple second connecting pipes 10, which then flows into multiple storage tanks 23, filling the multiple storage tanks 23 with coolant. The coolant then cools the flue gas through the walls of the storage tanks 23. Finally, multiple first waterproof exhaust valves 15 are opened to release the pre-cooled flue gas. The flue gas is discharged into the housing 1, and then the first water pump 7 is started to draw water into the first connecting pipe 8 and spray it out from the spray plate 20 to cool the flue gas a second time. The water will accumulate on the inclined plate 22. Then, multiple second exhaust valves 21 are opened to discharge the flue gas. When water needs to be discharged, multiple hydraulic rods 18 are started to push the sealing plate 3 down. Under the guiding effect of the inclined plate 22, the water will be discharged to the outside of the housing 1. The staff can receive it. Multiple drain valves 13 can be opened to discharge the coolant. When the liquid generated inside the multiple cylinders 14 due to the cooling of the flue gas is to be treated, multiple end caps 16 are opened and the housing 1 is tilted slightly so that the liquid generated by the cooling of the flue gas can flow out from the right end of the cylinder 14. In other cases, the housing 1 can be limited by the external pin through the round hole of the round hole bending plate 11 and the round hole shaft 12.
