Description
Technical Field
[0001] The utility model relates to the technical field of environmental protection, in particular to a smoke elimination and temperature reduction device. Background Art
[0002] Diesel generators are crucial equipment for powering various projects. Under certain operating conditions, diesel generator sets produce large amounts of black, blue, and white smoke containing harmful gases, causing significant pollution. Heat dissipation from high-temperature flue gas accounts for approximately one-third of the generator's energy consumption, and direct exhaust wastes heat. Effective exhaust gas removal, purification, and cooling measures, as well as waste heat recovery and utilization, are essential. High-temperature flue gas also poses a risk of thermal infrared exposure for military projects.
[0003] At present, the main smoke elimination and cooling treatment is mainly based on simple spraying smoke elimination and cooling treatment. However, the single spraying measure requires a large amount of water and is prone to produce a large amount of white fog in a specific climatic environment, which leads to the exposure of military targets. At the same time, it also causes a large amount of heat energy that cannot be recycled. Utility Model Content

[0031] Example:
[0032] like Figure 1 As shown, the utility model provides a smoke elimination and cooling device, comprising: a housing 1, a filter 2, an atomizer 3, a first heat exchange component and a cooling and dehumidifying component; along a first direction (such as Figure 1In the X direction), a smoke inlet 101 is formed at the first end of the shell 1, and a smoke exhaust port 102 is formed at the second end of the shell 1. The inner cavity of the shell 1 has a smoke channel connecting the smoke inlet 101 and the smoke exhaust port 102. The filter 2, the atomizer 3, the first heat exchanger assembly and the cooling and dehumidifying assembly are arranged in sequence in the smoke channel, wherein the filter 2 is arranged near the smoke inlet 101, and the cooling and dehumidifying assembly is arranged near the smoke exhaust port 102. A liquid tank 103 is provided at the bottom of the inner cavity of the shell 1, and the water inlet pipe of the atomizer 3 is connected to the liquid tank 103. The smoke channel is connected to the liquid tank 103 so that the atomized water sprayed by the atomizer 3 flows back to the liquid tank 103. The hot water outlet of the first heat exchange assembly is connected to the waste heat utilization equipment through a pipeline. The reaction liquid is stored in the liquid tank 103, and the atomizing nozzle of the atomizer sprays atomized water under the action of the high-pressure water pump, so that the atomized water is in full contact with the flue gas, and the falling atomized water returns to the liquid tank 103 for recycling. In this embodiment, the filter 2, the atomizer 3, the first heat exchange component and the cooling and dehumidification component are arranged in sequence inside the shell. Through the multi-stage and multi-type smoke elimination, purification, cooling and dehumidification facilities, the high-temperature flue gas discharged from the diesel generator set can be fully and efficiently purified and cooled, avoiding the generation of white fog and meeting the infrared camouflage requirements. In addition, the hot water outlet of the first heat exchange component in this embodiment is connected to the waste heat utilization equipment through a pipeline, and the hot water generated after the heat exchange is recycled and utilized, making full use of resources. Specifically, the waste heat utilization equipment can be one or more of the terminal radiator, water heater, hot water tank, hot water tap and fan coil unit, which are used for domestic water and heating terminals within the project.
[0033] To reduce the footprint of the smoke elimination and cooling device, the smoke duct is arranged in a circuitous manner along a second direction, which is angled with the first direction. In this embodiment, the second direction is perpendicular to the first direction. The filter 2, atomizer 3, and first heat exchange component are arranged in the positive direction of the second direction, while the cooling and dehumidification component is arranged in the negative direction of the second direction. In other embodiments, the layout of the components can be appropriately adjusted based on the space within the project.
[0034] In another embodiment, a through valve 18 is further provided, and the smoke passage is arranged in a circuitous manner along the second direction. A through hole is provided in the smoke passage so that the smoke inlet 101 and the smoke exhaust port 102 are connected in the first direction. The through hole is provided with the through valve 18 to open or close the through hole, and the second direction is at an angle (preferably 90°) to the first direction. Under normal operating conditions, the through valve 18 is in a closed state, and the smoke is eliminated and cooled through the circuitous smoke passage. When the smoke elimination and cooling device needs to be repaired, the through valve 18 is opened, the smoke passage of the closed box opens the through hole, and the smoke flows directly from the smoke inlet to the smoke exhaust port.
[0035] In this embodiment, a reaction pool 8 is further included. The reaction pool 8 is located below the first heat exchange component, that is, at the turning point of the flue gas channel. The atomized water sprayed from the atomizer 3 falls into the reaction pool 8. The reaction pool 8 has an overflow pipe 9. One end of the overflow pipe 9 is connected to the reaction pool 8, and the other end of the overflow pipe 9 is connected to the liquid tank 103. In this embodiment, the flue gas channel is connected to the liquid tank 103 by providing the reaction pool 8 and the overflow pipe 9, so that the atomized water sprayed from the atomizer 3 can flow back into the liquid tank 103. In this embodiment, a water suction pipe 14 and a first water pump 13 are provided. One end of the water suction pipe 14 is inserted into the liquid tank 103, and the other end of the water suction pipe 14 is connected to the atomizer 3 and the reaction pool 8 respectively through pipelines. The first water pump 13 is located in this section of the pipeline and is used to replenish the reaction liquid into the atomizer 3 and the reaction pool 8.
[0036] Specifically, when the reaction liquid is not in use, it flows into the liquid tank 103 through the reflux pipe to prevent the reaction liquid from clogging the reactor after losing water. When in use, the reaction liquid is pumped from the liquid tank 103 to the reaction tank 8 by the first water pump 13. After the reaction liquid is pumped to the reaction tank 8, a certain amount of cold water is first injected into the liquid tank 103, and the overflow water in the reaction tank 8 is received. If the water temperature in the liquid tank 103 does not exceed the set value, the first water pump 13 pumps the water in the liquid tank 103 to the atomizer. When the water temperature in the liquid tank 103 exceeds the set value, the drain valve is opened to discharge the water through the drain pipe 16, and at the same time, the float valve is opened to inject cold water into the liquid tank 103. The cycle continues.
[0037] This embodiment also includes a reactor 10. A reaction tube 1001 of the reactor 10 is inserted into the reaction tank 8. Flue gas, after heat exchange in the first heat exchange component, passes through the reaction tube 1001 and enters the reaction tank 8. The flue gas generates microbubbles through the reaction tube 1001, which further contact the reaction liquid to cool it. Simultaneously, the reaction liquid absorbs and purifies harmful components in the flue gas, further purifying the flue gas. The flue gas, purified in the reaction tank, then enters the cooling and dehumidification component.
[0038] Specifically, a vent hole 20 is provided on the reaction tube 1001, and the vent hole 20 is arranged on the tube wall of the reaction tube below the liquid level. The flue gas passes through the reaction tube 1001 and is discharged through the vent hole 20, reacts with the reaction liquid and forms bubbles, thereby increasing the contact surface with the reaction liquid and improving the smoke elimination, purification and cooling effect.
[0039] Specifically, the cooling and dehumidification assembly includes a second heat exchange assembly, a condensate baffle 6, and an air mixing box 7, arranged sequentially. The smoke inlet of the second heat exchange assembly is adjacent to the reaction tank 8, the exhaust port of the air mixing box 7 is connected to the smoke exhaust port 102, and the hot water outlet of the second heat exchange assembly is connected to the waste heat utilization device via a pipeline. In this embodiment, the second heat exchange assembly, the condensate baffle 6, and the air mixing box 7 are arranged sequentially in the opposite direction of the second direction. The second heat exchange assembly further exchanges heat with the flue gas purified by the reaction tank. The flue gas after heat exchange contains water vapor. After the condensate baffle 6 removes the water vapor from the flue gas, the flue gas is mixed with the outside air in the air mixing box 7, further equalizing the residual water vapor and temperature in the flue gas, so that the flue gas meets the emission standards, and is then discharged from the smoke exhaust port 102. The condensate baffle 6 is corrugated to increase the contact area with the flue gas and improve the condensation effect. The air mixing box 7 is also provided with an air mixing control valve 19 for adjusting the temperature and humidity of the exhaust flue gas.
[0040] Specifically, the first heat exchange assembly includes at least two first heat exchangers 4; the at least two first heat exchangers 4 are connected in series, and the hot water outlets 11 of the at least two first heat exchangers 4 are connected to the waste heat utilization device via pipelines. The first heat exchangers 4 can be configured as a single, two, or multiple stages to further cool the atomized water and flue gas and absorb waste heat.
[0041] The second heat exchange assembly includes at least two second heat exchangers 5; these are connected in series, with the hot water outlets 11 of the at least two second heat exchangers 5 connected via pipelines to the hot water outlet of the first heat exchange assembly, supplying hot water to the waste heat equipment. The second heat exchanger 5 can be configured as a single, two, or multiple stages, further cooling the purified flue gas and absorbing waste heat. The first and second heat exchange assemblies can also be connected in series, with the water outlet of the second heat exchange assembly connected to the water inlet of the first heat exchange assembly.
[0042] In this embodiment, an exhaust fan 12 is also included, and the exhaust fan 12 is arranged in the smoke exhaust port 102, and is used to discharge the smoke in the shell 1 after cooling and smoke reduction. A second water pump 15 is also included; the second water pump 15 is used to pump cooling water into the first heat exchanger 4 and the second heat exchanger 5. A drain pipe 16 is also included, and the drain pipe 16 is located at the bottom of the shell 1 and is connected to the liquid tank 103, and is used to discharge the reaction liquid in the liquid tank 103. A tripod 17 is also included, and the tripod 17 is arranged at the bottom end of the shell 1 to support the shell 1. This smoke elimination and cooling device can be equipped with a differential pressure gauge, a thermometer, a liquid level gauge, etc. to monitor the gas and liquid conditions in each section, and is linked with the water pump and the fan, and is automatically controlled by the automatic control equipment to achieve intelligent management.
[0043] During specific use: the smoke from the diesel generator enters through the smoke inlet 101, and a filter 2 is set behind the smoke inlet 101 to make the high-temperature smoke undergo preliminary filtration and smoke elimination after passing through the filter 2. The atomizer 3 is set behind the filter 2. Under the action of the high-pressure water pump, the atomizing nozzle of the atomizer 3 sprays atomized water, so that the atomized water is fully in contact with the smoke, further eliminating the smoke and cooling it; then two first heat exchangers 4 are arranged, and the atomized water and the smoke pass through the first heat exchanger, and are further cooled and absorb the residual heat under the action of the first heat exchanger 4; the reactor 10 is set after the first heat exchanger 4, and the reaction of the reactor 10 Tube 1001 is inserted into the reaction liquid in reaction tank 8; the flue gas generates microbubbles through reaction tube 1001, which further contact with the reaction liquid to cool it down. At the same time, the reaction liquid absorbs and purifies harmful components in the flue gas; the flue gas treated by reactor 10 and reaction tank 8 enters the second heat exchanger 5 through the flue gas channel, undergoes heat exchange and cooling through two second heat exchangers 5, and condenses at the condensate baffle 6 to precipitate moisture in the flue gas. The flue gas then enters the air mixing box 7 and mixes with the outside air. After heat exchange, cooling, condensation and dehumidification, the flue gas is discharged through the exhaust port 102 under the action of the exhaust fan 12. Through multi-stage and multi-type smoke elimination, purification, cooling and dehumidification facilities, the high-temperature flue gas discharged by the diesel generator set can be fully and efficiently purified and cooled to meet the national emission requirements; at the same time, the generation of white fog is avoided and the intensity of the flue gas thermal infrared radiation is effectively reduced. For use scenarios where visible light camouflage and thermal infrared camouflage of flue gas are required, the camouflage effect can be effectively improved. Moreover, the heated water generated by the first heat exchanger 4 and the second heat exchanger 5 is also delivered to the waste heat utilization equipment for use, thereby making full use of resources.
