Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization and dust removal, in particular to atomization desulfurization and dust removal equipment. Background Art

[0002] Atomization desulfurization and dust removal equipment is a highly efficient environmental protection equipment, mainly used to treat harmful substances in flue gas, such as sulfur dioxide and smoke dust, etc. The working principle of atomization desulfurization and dust removal equipment is mainly to allow boiler flue gas to enter the reactor, spray the absorption liquid through the nozzle combination spray layer, and produce a high-intensity chemical reaction after the droplets fully contact the flue gas. The flue gas after dust removal is dehydrated by the dehydrator to achieve gas-water separation and purify the flue gas.

[0003] After the existing flue gas enters the device body, it is in a state of natural diffusion, so the contact time with the liquid sprayed from the nozzle is limited, resulting in insufficient contact between the flue gas and the liquid, and low desulfurization efficiency;

[0004] The existing patent (Announcement No.: CN214973016U) discloses a boiler flue gas atomization desulfurization and dust removal device, which drives the active rod to drive multiple branch rods to rotate through a driving device, thereby accelerating the flow of flue gas, thereby making the flue gas and liquid contact more fully, and improving the desulfurization effect of the device to a certain extent.

[0005] In response to the above problems, although the solution provided by the existing patent is that the driving device drives the stirring rod to rotate so that the smoke and liquid contact more fully, it requires an additional driving device to drive the stirring rod to rotate during use, and the driving device consumes energy during operation, which will lead to an increase in overall energy consumption. When running for a long time or under high load, the operating cost is increased. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 , an atomizing desulfurization and dust removal device, comprising a processing tank 1, the left side of the processing tank 1 is connected with an air inlet pipe 2, the upper end of the processing tank 1 is connected with an exhaust pipe 3, the end of the exhaust pipe 3 is connected with a negative pressure fan 4, one side of the processing tank 1 is provided with a liquid storage mechanism for storing desulfurization liquid, and the inside of the processing tank 1 is provided with an atomizing mechanism for spraying the desulfurization liquid;

[0028] The liquid storage mechanism includes a liquid storage tank 5, which is arranged on one side of the processing tank 1. A high-pressure delivery pump 51 is fixed to the upper end of the liquid storage tank 5 by bolts. The output end of the high-pressure delivery pump 51 is connected to a delivery pipe 52. The delivery pipe 52 passes through the inner wall of the processing tank 1 and is connected to a mounting shell 53. A hydrodynamic blade 54 is installed inside the mounting shell 53. A transmission rod 55 is fixed to the lower end of the hydrodynamic blade 54. The lower end of the transmission rod 55 is rotatably connected to the inner wall of the mounting shell 53 through a bearing. A mounting pipe 56 is fixed to the lower surface of the transmission rod 55. Three stirring blades 57 are symmetrically fixed to the outer wall of the mounting pipe 56.

[0029] By adopting the above technical solution, before using the atomizing desulfurization and dust removal equipment, first fix the processing tank 1, the negative pressure fan 4 and the liquid storage tank 5 to the appropriate position by bolts, connect the external exhaust pipe and the intake pipe 2, and then connect the exhaust pipe 3 and the pipeline of the next external processing equipment. When in use, the external exhaust gas enters the processing tank 1 through the intake pipe 2, and at the same time, the high-pressure delivery pump 51 extracts the desulfurization liquid stored in the liquid storage tank 5 through the pipeline, and delivers it to the installation shell 53 through the delivery pipe 52. Since the installation shell 53 is provided with a water-dynamic blade 54, The high-pressure water flow will push the hydraulic blades 54 to rotate, and the rotation of the hydraulic blades 54 drives the mounting tube 56 to rotate through the transmission rod 55. Since the desulfurization liquid is continuously transported, the hydraulic blades 54 drive the mounting tube 56 to rotate. At this time, the stirring blades 57 stir and mix the exhaust gas and the desulfurization liquid. The equipment does not need to use additional equipment to drive the stirring blades 57, thereby achieving energy-saving and environmental protection effects, reducing the energy consumed by the stirring mechanism during operation, and ensuring the desulfurization effect of the desulfurization liquid. The dust in the exhaust gas condenses into nuclei after contact with the mist water.

[0030] Specifically, Figure 2-Figure 4 As shown, the atomization mechanism includes a connecting pipe 6, which is connected to the lower end of the mounting shell 53, and the end of the connecting pipe 6 is connected to a fixed shell 61. The outer wall of the fixed shell 61 is fixed with a protective net 62 fixed to the inner wall of the processing tank 1, and both ends of the fixed shell 61 are inlaid with fixed bearings 63 sleeved on the outer wall of the transmission rod 55. The outer surface of the transmission rod 55 is sleeved with two sealing rings 64 fixed to the fixed shell 61. The outer surface of the transmission rod 55 is provided with a through hole 65 interconnected with the fixed shell 61, and the interior of the transmission rod 55 is provided with a flow cavity 66 interconnected with the through hole 65. Five atomizing nozzles 67 interconnected with the flow cavity 66 are equidistantly installed on the lower surfaces of the three stirring blades 57. The right side of the processing tank 1 is connected with a waste liquid pipe 7, and the outer surface of the waste liquid pipe 7 is fixed with a valve 8. The upper surface of the liquid storage tank 5 is fixed with a liquid level sensor 9 by bolts, and the outer surface of the liquid storage tank 5 is connected with a liquid adding pipe 10.

[0031] By adopting the above technical solution, the desulfurization liquid continuously enters the installation shell 53 through the connecting pipe 6 and enters the fixed shell 61. The desulfurization liquid flows into the flow cavity 66 through the through hole 65 opened on the installation pipe 56, and then is discharged into the inside of the three groups of stirring blades 57, and is sprayed out through the atomizing nozzle 67 to desulfurize the exhaust gas. The fixed bearing 63 arranged between the installation shell 53 and the installation pipe 56 does not drive the installation shell 53 to rotate when the installation pipe 56 rotates, and the sealing ring 64 arranged can improve the sealing effect and reduce the desulfurization liquid in the installation shell 53. When leakage occurs between the mounting shell 53 and the mounting pipe 56, the atomizing nozzle 67 will be driven to move when spraying the shedding liquid. The desulfurized waste gas is discharged from the exhaust pipe 3 through the protective net 62. By opening the valve 8 on the waste liquid pipe 7, the sprayed liquid is discharged to the outside with the dust. The liquid level sensor 9 is set to detect the liquid in the liquid storage tank 5. When it is detected that there is too little liquid, the liquid level sensor 9 sends the detection data to the single-chip microcomputer, and the single-chip microcomputer controls the external liquid adding equipment to add desulfurized liquid into the liquid adding pipe 10.

[0032] Working principle: the external exhaust gas enters the treatment tank 1 through the air intake pipe 2, and the high-pressure delivery pump 51 extracts the desulfurization liquid stored in the liquid storage tank 5 through the pipeline and sends it to the installation shell 53. The high-pressure water flow will drive the hydraulic blades 54 to rotate, and the rotation of the hydraulic blades 54 drives the installation pipe 56 to rotate through the transmission rod 55. The desulfurization liquid flows into the flow cavity 66 through the through hole 65 opened on the installation pipe 56, and is sprayed out through the atomizing nozzle 67 to desulfurize the exhaust gas. The hydraulic blades 54 drive the installation pipe 56 to rotate, and the atomizing nozzle 67 will be driven to move when spraying the desulfurization liquid. At this time, the stirring blades 57 stir and mix the exhaust gas and the sprayed desulfurization liquid. The equipment does not need to use additional equipment to drive the stirring blades 57, so as to achieve energy-saving and environmental protection effects, thereby ensuring the desulfurization effect of the desulfurization liquid. The dust in the exhaust gas condenses into nuclei after contacting the mist water, and the desulfurized exhaust gas passes through the protective net 62 and is discharged from the exhaust pipe 3.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
