[0002] During the use of thermal power boilers, a large amount of flue gas will be generated. Therefore, a flue gas desulfurization system for thermal power boilers is required to desulfurize the flue gas before it can be discharged.

[0003] Chinese patent document CN208340491U discloses a flue gas desulfurization device comprising an intake pipe, a waste heat recovery tank, a thermal converter, calcium oxide granules, a sodium hydroxide solution, an atomizing nozzle, and a thionine solution. The intake pipe is mounted on the left side of the waste heat recovery tank, and a dust filter is installed within the waste heat recovery tank.

[0025] A method for integrated treatment of flue gas desulfurization and waste liquid from a thermal power boiler, using the above-mentioned integrated treatment device for flue gas desulfurization and waste liquid from a thermal power boiler, comprises the following steps:

[0026] S1. Start the cylinder to drive the barrel 1 downward, thereby spraying the desulfurization liquid through the liquid discharge mechanism, driving the power storage component downward, and allowing the power storage component to accumulate force for subsequently driving the plug-in part 1 to rotate;

[0027] S2. When the plug-in part 1 is plugged into the slot in the inner cavity of the rotating part, the power storage component drives the plug-in part 1 to rotate the rotating part, and the scraping rod scrapes the inner walls of the desulfurization cylinder and the collection cylinder;

[0028] S3, the rotating part is pressed downward by the plug-in part 1, so that the bottom end of the plug-in part 2 is inserted into the plug-in rod. When the rotating part rotates, the plug-in rod is driven to rotate, thereby driving the conical ring to rotate. When the conical ring rotates, it contacts the conical block, driving the filter plate to vibrate in the inner cavity of the filter box;

[0029] S4. The large particles in the waste liquid are filtered through the filter plate in the filter box, and then the waste liquid is discharged from the drain pipe at the bottom of the filter box.

[0030] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0031] The desulfurization liquid is loaded above the liquid outlet plate in the inner cavity of the desulfurization cylinder. The starting cylinder drives the cylinder to descend, and then drives the circular plate to descend, thereby pushing the desulfurization liquid above the liquid outlet plate toward the fixed tube, and then pushing the lower pressure part toward the movable tube, so that the desulfurization liquid is sprayed from the spray hole to the inner cavity of the desulfurization cylinder, desulfurizing the flue gas in the inner cavity of the desulfurization cylinder, thereby realizing that when not in use or when loading with desulfurization liquid, the movable tube rises to scrape the spray hole, thereby avoiding dirt at the spray hole, which causes the spray hole to be blocked.

[0032] When tube one descends, it drives tube two down with it. At this time, the conical part is clamped by the triangular block, so that the conical part cannot descend, thereby pulling the pull rope in the inner cavity of tube two out of tube two, and causing the round rod to rotate to drive the coil spring to contract and store force. When the circular plate descends to the bottom, the plug-in part one is plugged into the slot. At this time, the pull rope is pulled to the longest, so that the conical part pushes the triangular block open and descends. Then tube two drives the slot to rotate, thereby driving the scraper rod to rotate through the slot, and the scraper rod is used to scrape and clean the inner walls of the desulfurization tube and the collection tube.

[0033] When the plug-in part 1 is inserted into the slot, the slot is driven to descend, and the slot drives the plug-in part 2 to descend and insert into the telescopic rod 1, thereby driving the cone ring to rotate. When the cone ring contacts the cone block, the cone block is squeezed to move, thereby causing the filter plate to vibrate, thereby achieving the filtration of large particles of impurities in the waste liquid through the filter plate in the filter box, and making the filter plate vibrate intermittently, avoiding the occurrence of clogging of the filter plate.

[0047] A cleaning mechanism installed in the desulfurization cylinder 1;

[0048] A liquid discharge mechanism, which is installed in the desulfurization cylinder 1 and is used to spray the desulfurization liquid;

[0049] The cleaning mechanism includes a driving assembly, a power storage assembly, a transmission assembly, a filtering assembly, a vibration assembly and a plug-in part 9; the driving assembly is installed on the desulfurization cylinder 1 and is used to drive the power storage assembly to rotate and store power and the liquid discharge mechanism to spray the desulfurization liquid; the power storage assembly is installed in the driving assembly; the transmission assembly is installed in the collecting cylinder 2 and is plugged into the descending plug-in part 9; the filtering assembly is installed at the bottom of the collecting cylinder 2 and is used to filter the waste liquid; the vibration assembly is installed in the filtering assembly and is plugged into the descending transmission assembly; the plug-in part 9 is installed on the rotating shaft of the power storage assembly; the driving assembly causes the power storage assembly to descend, and the plug-in part 9 descends to the bottom to plug into the transmission assembly, and the transmission assembly drives the vibration assembly to cause the filtering assembly to vibrate.

[0050] The drive assembly includes cylinder 4, cylinder 1 5 and cylinder 2 8;

[0051] Cylinder 4 is installed on the desulfurization cylinder 1, and cylinder 1 5 is installed on the output shaft of cylinder 4; the bottom end of cylinder 1 5 is connected to cylinder 2 8.

[0052] Cylinder 4 drives cylinder 1 5 to descend, and cylinder 1 5 drives cylinder 2 8 to descend.

[0053] The power storage assembly includes a coil spring 6, a round rod 7, a pull rope 10 and a limit unit;

[0054] The coil spring 6 is installed in the tube 1 5, and the center thereof is connected to the round rod 7, and the round rod 7 is connected to the plug-in part 1 9; the two ends of the pull rope 10 are respectively connected to the plug-in part 1 9 and the limiting unit.

[0055] When the cylinder 2 8 descends, the pull rope 10 is pulled out of the inner cavity of the cylinder 2 8 by the limiting unit, thereby causing the round rod 7 and the plug-in part 1 9 to rotate, thereby causing the coil spring 6 in the inner cavity of the cylinder 1 5 to contract.

[0056] The limiting unit includes a bottom plate 11, a conical portion 12, a third elastic member 36 and a triangular block 37;

[0057] The upper and lower sides of the bottom plate 11 are respectively connected to the pull rope 10 and the conical part 12; the lower side of the bottom plate 11 is placed on the cylinder 2 8; the two ends of the elastic member 3 36 are respectively connected to the liquid discharge mechanism and the triangular block 37; the triangular block 37 is snap-fitted to the conical part 12.

[0058] When the second cylinder 8 descends to the longest distance, the plug-in part 9 is inserted into the inner cavity of the slot 17 and presses the rotating part 16 downward. At this time, the conical part 12 is pulled downward, so that the conical part 12 pushes the triangular block 37 toward the direction of the elastic part 3 36. Then the coil spring 6 releases its elasticity, driving the plug-in part 9 to rotate.

[0059] The transmission assembly includes a mounting frame 13, a spring 14, a rotary disc 15, a rotating portion 16, a plug-in portion 2 18 and a scraping rod 38;

[0060] The mounting frame 13 is installed at the bottom end of the collecting cylinder 2, and the two ends of the spring 14 are respectively connected to the mounting frame 13 and the turntable 15; the turntable 15 and the rotating part 16 are movably connected; the plug-in part 2 18 is installed in the rotating part 16, passes through the turntable 15 and is located above the filter bin 3; the rotating part 16 is provided with a slot 17 that is plugged into the plug-in part 1 9; the scraping rod 38 is installed on the outside of the rotating part 16.

[0061] Through the movable connection between the turntable 15 and the rotating part 16, the rotating part 16 can only drive the plug-in part 2 18 to rotate when it rotates, and through the movable connection between the turntable 15 and the rotating part 16, the rotating part 16 can be lifted and lowered by the elasticity of the spring 14 and can also rotate freely.

[0062] The filter assembly includes a filter box 22, a tilting block 23, an elastic member 24, a filter plate 25, a baffle 26 and a drain pipe 27;

[0063] The filter box 22 is inserted into the filter chamber 3, and the tilting block 23 is installed on the inner side of the filter box 22; the two ends of the elastic member 24 are respectively connected to the tilting block 23 and the filter plate 25, and a baffle 26 is installed on the filter plate 25, and the baffle 26 is slidably connected to the tilting block 23; the bottom end of the filter box 22 is connected to the drain pipe 27.

[0064] The waste liquid is filtered through the filter box 22 in the inner cavity of the filter chamber 3 , and the large particles of impurities in the waste liquid are filtered on the top of the filter plate 25 .

[0065] The vibration assembly includes a telescopic rod 19, a plug rod 20, a conical ring 21 and a conical block 28;

[0066] The telescopic rod 19 is installed in the filter box 22, the plug rod 20 is movably sleeved in the telescopic rod 19, the bottom of the plug rod 20 is connected to the conical ring 21, and the conical block 28 is installed on the filter plate 25 and contacts the conical ring 21.

[0067] When the conical ring 21 rotates, the conical block 28 is first pressed downward, and the elastic member 24 is stretched. When the conical ring 21 continues to rotate, the pulling force of the elastic member 24 drives the filter plate 25 to move upward and reset, thereby causing the filter plate 25 to vibrate briefly, and then causing the impurities collected above the filter plate 25 to vibrate, thereby preventing the impurities collected in the waste liquid from clogging the filter plate 25.

[0068] When the second plug-in portion 18 is inserted into the inner cavity of the plug-in rod 20, the conical ring 21 is driven to rotate.

[0069] The baffle 26 protects the elastic member 24, thereby preventing the elastic member 24 from contacting the waste liquid, which would cause the elastic member 24 to accumulate dirt.

[0070] Example 2, as Figure 2-5As shown, the present invention proposes a thermal power boiler flue gas desulfurization and waste liquid integrated treatment device. Compared with the first embodiment, the liquid discharge mechanism of this embodiment includes a circular plate 29, a liquid discharge plate 30, a fixed pipe 31, a spray hole 32, a second elastic member 33, a lower pressure portion 34, a one-way liquid inlet pipe 40 and a movable pipe 35;

[0071] The circular plate 29 is installed on the outer surface of the cylinder 1 5, the liquid outlet plate 30 is installed in the desulfurization cylinder 1, the fixed tube 31 is installed in the liquid outlet plate 30, and a spray hole 32 is opened on the fixed tube 31. The two ends of the elastic member 2 33 are respectively connected to the fixed tube 31 and the downward pressure part 34, and the bottom end of the downward pressure part 34 is installed with a movable tube 35; the movable tube 35 is movably sleeved on the outer surface of the fixed tube 31 and blocks the spray hole 32; the two ends of the one-way liquid inlet pipe 40 are respectively connected to the desulfurization cylinder 1 and the bottom of the inner cavity of the storage cylinder 41.

[0072] The connection between the one-way liquid inlet pipe 40 and the desulfurization cylinder 1 is located above the liquid outlet plate 30 .

[0073] Connecting pipes 39 are installed on both sides of the desulfurization cylinder 1, and a stirring device 42 is installed in the middle of the storage cylinder 41.

[0074] Elastic member 2 33 and elastic member 3 36 are both composed of spring 2 and telescopic rod 2. Spring 2 is sleeved on the outer periphery of telescopic rod 2. The elastic movable tube 35 and triangular block 37 provided by the spring can move, and the spring is positioned and guided by telescopic rod 2 to avoid displacement during the deformation of the spring.

[0075] Example 3, as Figure 1-11 As shown, the present invention proposes a method for integrated treatment of flue gas desulfurization and waste liquid of a thermal power boiler, which adopts an integrated treatment device for flue gas desulfurization and waste liquid of a thermal power boiler according to the first embodiment, and includes the following steps:

[0076] S1. Start cylinder 4 to drive barrel 5 downward, thereby spraying desulfurization liquid through the liquid discharge mechanism, driving the power storage component downward, and allowing the power storage component to accumulate force for subsequently driving the plug-in part 9 to rotate;

[0077] S2. When the plug-in part 9 is plugged into the slot 17 in the inner cavity of the rotating part 16, the power storage component drives the plug-in part 9 to rotate the rotating part 16, and the scraping rod 38 scrapes the inner walls of the desulfurization cylinder 1 and the collection cylinder 2;

[0078] S3. The rotating portion 16 is pressed downward by the plug-in portion 19, so that the bottom end of the plug-in portion 2 18 is inserted into the plug-in rod 20. When the rotating portion 16 rotates, the plug-in rod 20 is rotated, thereby driving the conical ring 21 to rotate. When the conical ring 21 rotates, it contacts the conical block 28, driving the filter plate 25 to vibrate in the inner cavity of the filter box 22.

[0079] S4. Large particles in the waste liquid are filtered through the filter plate 25 in the filter box 22, and then the waste liquid is discharged from the drain pipe 27 at the bottom end of the filter box 22.

[0080] In summary, in the present invention, the flue gas input pipe and output pipe are respectively connected to two connecting pipes 39, and the desulfurization liquid is added to the inner cavity of the storage cylinder 41. At this time, the circular plate 29 is located above the liquid outlet plate 30, and then the cylinder 4 is started to drive the circular plate 29 to move upward, and then the desulfurization liquid in the inner cavity of the storage cylinder 41 is drawn into the inner cavity of the desulfurization cylinder 1 between the circular plate 29 and the liquid outlet plate 30 through the suction force of the circular plate 29 and the liquid outlet plate 30.

[0081] Then, flue gas is input into the inner cavity of the desulfurization cylinder 1, and then the cylinder 4 is started to drive the cylinder 5 and the circular plate 29 to descend. The desulfurization liquid above the liquid outlet plate 30 is squeezed by the descending circular plate 29. The squeezed desulfurization liquid presses the lower pressure part 34 of the inner cavity of the fixed tube 31 downward, thereby squeezing the movable tube 35 downward, and then the desulfurization liquid is sprayed out from the spray hole 32 into the inner cavity of the desulfurization cylinder 1, thereby desulfurizing the flue gas input into the inner cavity of the desulfurization cylinder 1.

[0082] When tube 1 5 descends, it drives tube 2 8 to descend. At this time, the triangular block 37 clamps the conical part 12, so that the conical part 12 cannot descend, thereby pulling out the pull rope 10 in the inner cavity of tube 2 8, thereby rotating the round rod 7. When the round rod 7 rotates, the coil spring 6 contracts and accumulates force. When tube 2 8 descends to the longest distance, the plug-in part 19 descends to press the rotating part 16, and during the rotation process, the plug-in part 19 can drive the rotating part 16 to rotate as long as it is aligned with the slot 17. Subsequently, during the rotation of the rotating part 16, the scraping rod 38 is driven to rotate to scrape the inner wall of the collection tube 2.

[0083] When the rotating part 16 is pressed down by the plug-in part 9, the rotating part 16 also descends, and the rotating part 16 drives the plug-in part 2 18 to descend and insert into the inner cavity of the plug-in rod 20, thereby driving the conical ring 21 to rotate. When the conical ring 21 rotates, the filter plate 25 is driven to move through the fit between the conical ring 21 and the conical block 28. At this time, due to the elasticity of the elastic part 1 24, when the conical ring 21 squeezes the conical block 28, the filter plate 25 also vibrates, thereby clearing the impurities collected above the filter plate 25.

[0084] The second plug-in portion 18 is driven down by the rotating portion 16 before being inserted into the inner cavity of the plug-in rod 20, driving the plug-in rod 20 to rotate, thereby avoiding the situation where the filter box 22 is blocked by the second plug-in portion 18 when the filter box 22 is pulled out of the inner cavity of the filter chamber 3.

[0085] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
