Description

Technical Field

[0001] The invention relates to the technical field of flue gas desulfurization, and in particular to an environmentally friendly and energy-saving flue gas desulfurization device. Background Art

[0002] Thermal power generation refers to a method of generating electricity by converting the heat energy generated by the combustion of combustibles into electrical energy through a power generation device. A large amount of sulfur-containing waste gas will be generated in the process of thermal power generation. These waste gases need to be desulfurized before they can be discharged to reduce the pollution of the waste gas to the environment. The desulfurization of waste gas includes the step of spray purification. The absorption slurry is sprayed into the spray tower through the nozzle atomization, dispersed into fine droplets to form a huge gas-liquid contact surface, thereby covering the entire cross-section of the spray tower. Through these absorption slurries, most of the impurities in the waste gas and the preliminary desulfurization operation can be removed. The waste gas treated by the spray device will be introduced into the interior of the next purification treatment device for further purification and desulfurization treatment.

[0003] However, the existing spraying devices used in flue gas desulfurization have the following disadvantages:

[0004] 1. It does not have the function of adjusting the spray spacing. When the spray spacing is dense, it will cause excessive overlap of gas and liquid, and the atomized absorption liquid cannot fully react with the flue gas, resulting in poor desulfurization and purification effects. When the spray spacing is sparse, the purification efficiency will be reduced, and a longer spray channel needs to be set up, which takes up a large space and is inconvenient to use.

[0005] 2. There is no structure to prevent gas from escaping when the liquid is recovered. When the collected absorption liquid is discharged, the gas inside the pipeline is easy to escape from the liquid recovery pipeline, and the stability is poor. Summary of the invention

[0006] The disclosed embodiment relates to an environmentally friendly and energy-saving flue gas desulfurization device, which has a channel component and a spray component, wherein the channel component can spray out the absorption liquid through a pipeline mechanism in an atomized manner, thereby increasing the gas-liquid contact surface and covering the entire cross-section of the purification channel. Most of the impurities in the exhaust gas and the preliminary desulfurization operation can be removed through these absorption slurries. At the same time, the channel component can realize the function of sealingly recovering the absorption liquid to avoid the escape of flue gas inside the channel seat during the liquid recovery process. The desulfurization and purification operation is stable, and the use spacing between the pipeline modules can be adjusted by an adjustment mechanism.

In use, the coordinated use of the channel assembly 1 and the pipeline mechanism can realize the function of atomizing and spraying the absorption liquid, thereby realizing the preliminary desulfurization and purification operation of the flue gas. A spray channel 3013 is provided inside the telescopic pipe 301, and the middle part of the spray channel 3013 is connected to the atomizing nozzle 302.

[0047] In the embodiment of the present disclosure, a drainage groove 1031 is provided on the outside of the roller body of the drainage roller 103, and there are three drainage grooves 1031. The angle between adjacent drainage grooves 1031 is one hundred and twenty degrees. In use, the absorbed liquid after use in the purification channel 1013 will enter the interior of the liquid collecting channel 1014 for collection, and the recovered absorbed liquid will flow into the interior of the drainage groove 1031 facing the drainage roller 103. The liquid level sensor 105 can monitor the liquid level of the absorbed liquid recovered in the liquid collecting channel 1014. When the liquid level is much higher than the top of the drainage roller 103, the liquid level sensor 105 will connect the power supply of the drive motor 104 through the control device. The drive motor 104 can drive the drainage roller 103 to rotate when rotating, and the drainage roller 103 will rotate. At this time, the drainage roller 103 that was originally used upward will rotate to a downward state, thereby discharging the liquid inside the drainage groove 1031, and in this process, the other drainage groove 1031 will rotate to an upward state to continue collecting the recovered absorption liquid. The continuous rotation of the drainage roller 103 can realize the discharge of the absorbed liquid recovered inside the collection channel 1014, and because the liquid level of the recovered absorption liquid is much higher than the top of the drainage roller 103, the collection channel 1014 is always in a closed state under the action of the liquid and the drainage roller 103, and the phenomenon of smoke escaping from the purification channel 1013 will not occur. It is stable to use, and when the liquid level drops to a certain height, the liquid level sensor 105 will disconnect the power supply of the drive motor 104 through the control device, and the degree of automation is high.

[0048] In the embodiment of the present disclosure, the rod body of the transmission rod 201 is provided with a thread on the outside, and the transmission rod 201 is screwed to the inside of the positioning seat 203 through the rod body thread, a transmission gear 2011 is provided on the side of the transmission rod 201, and a synchronization gear 1071 is provided on the outside of the rod body of the synchronization rod 107, the gear teeth of the synchronization gear 1071 and the transmission gear 2011 are meshed for transmission, the bottom of the operating rod 106 is meshed with the gear teeth of the transmission gear 2011 of one of the transmission rods 201 through the gear, and the gear at the bottom of the operating rod 106 and the synchronization gear 1071 do not interfere with each other, the number of synchronization gears 1071 is the same as the number of spray assemblies, and in use, the use spacing between the pipeline modules 3 can be adjusted by the operating rod 106, which can adapt to the rapid desulfurization and purification operations of flue gas under different conditions and concentrations. When the operating rod 106 is rotated, the gear at the bottom of the operating rod 106 can drive the transmission rod 201 that is transmitted thereto to rotate. When the transmission rod 201 rotates, the rod body thread can drive the positioning seat 203 to move horizontally. When the positioning seat 203 moves, it can drive the second telescopic pipe 301 on the left to move, thereby changing the use spacing between the first and second telescopic pipes 301 on the left. Under the cooperation of all scissor top rods 303 and scissor bottom rods 304, all (except the first telescopic pipe 301 on the left) telescopic pipes 301 will move synchronously to change the use spacing, that is, change the injection spacing between the atomizing nozzles 302, and the adjustment is fast and convenient. Under the cooperation of the transmission gear 2011 and the synchronous gear 1071, the pipe modules 3 of all pipe mechanisms can change the use spacing synchronously, and the adjustment is stable.

[0049] In the embodiment of the present disclosure, a track rod 3011 with a regular polygonal cross-section is provided on the left side of the telescopic pipe 301, and a track groove 3012 is provided inside the right side of the telescopic pipe 301. The track rod 3011 is inserted into the track groove 3012 of the adjacent telescopic pipe 301. The track groove 3012 can limit the moving trajectory of the telescopic pipe 301 during adjustment through the track rod 3011, so that the telescopic pipe 301 will not be skewed or twisted during movement, which will cause the device to get stuck and fail, and the use is stable.

[0050] Specific usage and function of this embodiment: In the present invention, the coordinated use of the channel assembly 1 and the pipeline mechanism can realize the function of atomizing and spraying the absorption liquid, thereby realizing the preliminary desulfurization and purification operation of the flue gas. The flue gas can enter the interior of the purification channel 1013 through the inlet pipe 1011, and finally be discharged from the exhaust pipe 1012 to the interior of the next-level purification treatment device. In the process of the flue gas flowing through the purification channel 1013, the liquid supply equipment pumps the absorption liquid into the interior of the liquid supply channel 1021 through the pipeline. The liquid supply channel 1021 can transfer these liquids to the interior of the spray channel 3013 and finally spray them out through the atomizing nozzle 302, thereby realizing the purification and desulfurization treatment of the flue gas passing through the purification channel 1013. The absorbed liquid after use in the channel 1013 will enter the liquid collecting channel 1014 for collection, and the recovered absorbed liquid will flow into the liquid drain groove 1031 used by the drainage roller 103 facing upward. The liquid level sensor 105 can monitor the liquid level of the absorbed liquid recovered in the liquid collecting channel 1014. When the liquid level is much higher than the top of the drainage roller 103, the liquid level sensor 105 will connect the power of the drive motor 104 through the control device. The drive motor 104 can drive the drainage roller 103 to rotate when it rotates. When the drainage roller 103 rotates, the drainage roller 103 that was originally used upward will rotate to a downward state, thereby discharging the liquid in the drainage groove 1031, and in this process, the other drainage groove 1031 will rotate to a state of facing upward. Continue to collect the recovered absorption liquid. The recovered absorption liquid in the liquid collecting channel 1014 can be discharged through the continuous rotation of the drainage roller 103. Since the liquid level of the recovered absorption liquid is much higher than the top of the drainage roller 103, the liquid collecting channel 1014 is always in a closed state under the action of the liquid and the drainage roller 103. The phenomenon of smoke escaping from the purification channel 1013 will not occur. The use is stable. When the liquid level drops to a certain height, the liquid level sensor 105 will disconnect the power supply of the drive motor 104 through the control device. The use spacing between the pipeline modules 3 can be adjusted by the operating lever 106, which can adapt to the rapid desulfurization and purification operations of smoke in different situations and concentrations. When the operating lever 106 is rotated, the teeth at the bottom of the operating lever 106 The wheel can drive the transmission rod 201 that transmits to it to rotate. When the transmission rod 201 rotates, the rod body thread can drive the positioning seat 203 to move horizontally. When the positioning seat 203 moves, it can drive the second telescopic pipe 301 on the left to move, thereby changing the use spacing between the first and second telescopic pipes 301 on the left. Under the cooperation of all scissor top rods 303 and scissor bottom rods 304, all (except the first telescopic pipe 301 on the left) telescopic pipes 301 will move synchronously to change the use spacing, that is, change the injection spacing between the atomizing nozzles 302. The adjustment is fast and convenient, and under the cooperation of the transmission gear 2011 and the synchronous gear 1071, the pipe modules 3 of all pipe mechanisms can change the use spacing synchronously.
