Description

Technical Field

[0001] This utility model relates to the field of brine treatment technology, and in particular to a flue gas desulfurization system for treating brine. Background Technology

[0002] Brine treatment typically refers to the process of treating water with high salt concentrations to make it usable or meet emission standards. Brine treatment often involves related technological processes, during which a large amount of sulfur-containing flue gas is generated. If this sulfur-containing flue gas is discharged directly without effective treatment, it will cause serious environmental pollution, leading to a series of environmental problems such as acid rain. Therefore, flue gas desulfurization is crucial.

[0003] In existing flue gas desulfurization processes, filters are often installed to remove solid impurities from the flue gas. However, these filters still have many shortcomings in actual operation: Firstly, most existing filters are statically installed and can only intercept impurities. Over time, impurities accumulate on the filters, causing them to become clogged and severely affecting the flue gas throughput and filtration efficiency. This requires frequent manual cleaning or replacement of the filters, which is cumbersome and consumes a lot of manpower and resources. Secondly, additional power equipment is often needed to perform auxiliary functions, such as impurity cleaning, which undoubtedly increases energy consumption and operating costs, and is not in line with the current trend of energy conservation and environmental protection in industrial development. Utility Model Content

[0004] This invention proposes a flue gas desulfurization system for treating brine, in order to solve the problem of frequent manual cleaning or replacement of filters in existing flue gas desulfurization processes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flue gas desulfurization system for treating brine, comprising a treatment box, wherein a flue gas inlet pipe and an alkaline agent inlet pipe are connected to the treatment box, a filter screen is installed inside the flue gas inlet pipe, and further comprising:

[0006] A rotating plate is installed inside the flue gas inlet pipe and located in front of the filter screen, and the rotating plate can be driven to rotate by the incoming flue gas;

[0007] A gear transmission component and a striking assembly are provided. The striking assembly is disposed between a rotating plate and a filter screen. During the rotation of the rotating plate, the gear transmission component causes the striking assembly to periodically strike the filter screen.

[0008] Preferably, the gear transmission component includes a first gear, a second gear, and a third gear that are meshed together in sequence, and the rotating plate is mounted on the first gear via a connecting shaft.

[0009] Preferably, the striking assembly includes a connecting circular plate connected to a third gear via a coupling and a movable frame that can move along the length of the flue gas inlet pipe. A guide strip is connected to the connecting circular plate, and the bottom end of the guide strip can move along the movable frame. A forward connecting strip is connected to the side of the movable frame facing the filter screen, and multiple striking elements for striking are connected to the connecting strip.

[0010] Preferably, both ends of the movable frame are connected to connecting rods, and the inner wall of the flue gas inlet pipe is provided with guide grooves that fit the ends of the connecting rods.

[0011] Preferably, each of the striking elements on the connecting strip extends to a different length.

[0012] Preferably, the striking element includes a connecting post and a striking rod, the connecting post having a groove, and a spring connecting the inside of the groove and the end of the striking rod.

[0013] Preferably, the flue gas inlet pipe is further connected to a smoke guide plate near the port for guiding the flue gas to one side of the rotating plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] (1) High efficiency in cleaning impurities: Through gear transmission, the rotating plate is rotated by the impact of flue gas, which drives the knocking component to knock periodically on the filter screen, realizing the simultaneous filtration and cleaning of impurities, greatly improving the efficiency of impurity cleaning and filtration effect.

[0016] (2) Rational energy utilization: The system uses the flow force of flue gas as a power source to drive the rotating plate, gear transmission components and striking components to operate. No additional power equipment is required, which greatly saves energy consumption, improves energy utilization efficiency, and achieves the dual benefits of environmental protection and economy.

[0017] (3) The lengths of the striking parts are different. During the process of striking the filter screen, the pressure on different areas is different. This targeted action makes it easier for the attached impurities to fall off, significantly improving the efficiency of impurity cleaning, and thus enhancing the filter screen's ability to filter and clean impurities in flue gas.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] like Figures 1-4As shown, a flue gas desulfurization system for treating brine includes a treatment box 1, with a flue gas inlet pipe 2 and an alkaline agent inlet pipe 3 connected to the treatment box 1. An exhaust pipe is also connected to the top of the treatment box 1. A filter screen 7 is installed inside the flue gas inlet pipe 2 to filter solid impurities in the flue gas. The system also includes a gear transmission component 4, a rotating plate 6, and a striking component 8. The rotating plate 6 is located inside the flue gas inlet pipe 2 and in front of the filter screen 7. The rotating plate 6 can be rotated by the incoming flue gas. Inside the flue gas inlet pipe 2, near the port, a smoke guide plate is also connected to guide the flue gas to one side of the rotating plate 6. 5. Specifically, when flue gas is introduced, the flue gas is first guided by the smoke guide plate 5 from the rotating plate 6 on one side. With the pushing force of the flue gas, the knocking component 8 is set between the rotating plate 6 and the filter screen 7. During the rotation of the rotating plate 6, the knocking component 8 is periodically knocked on the filter screen 7 through the gear transmission component 4, so that the impurities adhering to the filter screen 7 fall off. A slag discharge pipe (not shown) can be set at the bottom of the flue gas inlet pipe 2 and directly opposite the position where the impurities on the filter screen 7 fall off. The impurities knocked off are discharged through the slag discharge pipe. However, during normal flue gas transportation, the slag discharge pipe is in the closed state. Waste can be discharged by periodically opening the slag discharge pipe.

[0033] Among them, see Figure 2 and Figure 3 As shown, the gear transmission component 4 includes a first gear 41, a second gear 42, and a third gear 43 that are meshed together in sequence. The first gear 41, the second gear 42, and the third gear 43 are all located outside the flue gas inlet pipe 2, and the rotating plate 6 is mounted on the first gear 41 through a connecting shaft.

[0034] See Figures 2-4 As shown, the striking assembly 8 includes a connecting circular plate 81 connected to the third gear 43 via a coupling and a movable frame 83 that can move along the length of the flue gas inlet pipe 2. A guide strip 82 is connected to the connecting circular plate 81, and the bottom end of the guide strip 82 can move along the movable frame 83. A forward connecting strip 85 is connected to the side of the movable frame 83 facing the filter screen 7. The connecting strip 85 is connected to a plurality of striking elements 86 for striking, and the end of the striking element 86 is provided with a striking hammer.

[0035] The movable frame 83 is connected to connecting rods 84 at both ends. The inner wall of the flue gas inlet pipe 2 is provided with guide grooves along the length direction that fit the ends of the connecting rods 84. The ends of the connecting rods 84 are slidably fitted with the guide grooves.

[0036] As described above, in practical use, the flue gas to be treated is introduced through the flue gas inlet pipe 2, and the alkaline agent to be neutralized is added through the alkaline agent inlet pipe 3. Sulfur dioxide and other substances in the flue gas react with the alkaline agent to achieve desulfurization.

[0037] During the flue gas introduction process, the flue gas is guided by the smoke guide plate 5, causing the rotating plate 6 to rotate, which in turn causes the first gear 41, the second gear 42, and the third gear 43 to rotate. This causes the guide strip 82 on the connecting circular plate 81 to rotate, thereby driving the moving frame 83 to move back and forth. During the back and forth movement of the moving frame 83, the filter screen 7 can be struck by the striking element 86 on the connecting strip 85, causing impurities on the filter screen 7 to fall off. This allows for simultaneous cleaning of impurities during filtration, and the power source is the flow power of the flue gas, eliminating the need for additional power and saving energy.

[0038] During the flue gas introduction process, the flue gas impacts the smoke guide plate 5 at a certain flow rate and volume. The flue gas can also impact the rotating plate 6 to rotate. The rotation of the rotating plate 6 causes the first gear 41 to rotate, thereby causing the third gear 43 to start rotating. When the third gear 43 rotates, the connecting circular plate 81 also rotates accordingly. As the connecting circular plate 81 rotates, the guide strip 82, located at the edge, slides within the groove of the moving frame 83 during its circular motion, causing the moving frame 83 to reciprocate. During this reciprocating motion, the connecting strip 85, rigidly connected to the moving frame 83, moves synchronously with it. When the moving frame 83 moves the connecting strip 85, the striking element 86 periodically strikes the filter screen 7. The vibration generated by the continuous striking of the striking element 86 causes impurities adhering to the filter screen 7 to fall off due to loss of adhesion. The entire process cleverly utilizes the inherent flow force of the flue gas as the power source for system operation, eliminating the need for additional power equipment such as motors and hydraulic pumps. This significantly saves energy consumption, improves energy efficiency, and achieves the function of simultaneously cleaning impurities on the filter screen 7 while filtering the flue gas.

[0039] Example 2

[0040] See Figure 5 and Figure 6 As shown, each striking element 86 on the connecting bar 85 has a different outward extension length, and the striking element 86 includes a connecting post 861 and a striking rod 863. A groove 862 is provided on the connecting post 861, and a spring 864 is connected between the inside of the groove 862 and the end of the striking rod 863.

[0041] As described above, the different lengths of each striking element 86 allow them to apply varying degrees of pressure to different areas of the filter screen 7. This differentiated pressure distribution ensures that different areas of the filter screen 7 are targeted, greatly facilitating the removal of impurities adhering to the filter screen 7 and effectively improving the impurity cleaning effect. Furthermore, when the longer striking element 86 presses against the filter screen 7, the spring 864 acts as a buffer, using its own compression deformation to offset some of the pressure. This prevents the longer striking element 86 from excessively compressing the filter screen 7, effectively protecting the filter screen 7 and extending its service life.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
