[0002] SDS desulfurization tower is a kind of equipment used for flue gas desulfurization, mainly used for flue gas purification in coal-fired power plants in the power industry.

[0003] After searching the Chinese patent with the publication number CN215842486U, a simple SDS desulfurization tower device is disclosed, which belongs to the field of flue gas desulfurization and purification technology. It includes an inlet cyclone, an outer wall of the desulfurization tower, an ash hopper, a guide pipe, a desulfurizer injection pipe, a partition plate, a desulfurization tower outlet, a level meter, a vibrator, a manhole, an ash discharge valve, a top guardrail, and a leg. The advantage is that through the reasonable arrangement of the inlet cyclone, the guide pipe inside the desulfurization tower, and the partition plate, the uniform arrangement of the desulfurizer injection pipe, and the special control of the flue gas flow rate inside the desulfurization tower, the conventional sodium-based dry desulfurization system can be effectively avoided. The problems such as large desulfurization tower dimensions, complex piping system, short contact time and insufficient contact between desulfurizer and flue gas, easy ash accumulation at the bottom of the desulfurization tower, and low desulfurization efficiency can be effectively guaranteed. The desulfurization reaction time of SDS is effectively guaranteed, the desulfurization efficiency is improved, and the flue gas purification effect is ensured.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] When the existing desulfurization tower is in use, it simply sprays the absorption liquid directly into the flue gas. In this way, the contact time between the absorption liquid and the flue gas is short, resulting in insufficient reaction and poor desulfurization effect. Utility Model Content

[0009] In some embodiments, the cleaning brush is in contact with the screen plate, and the transmission gear and the transmission gear ring are meshed with each other.

[0010] In some embodiments, the plurality of smoke inlets are evenly distributed in a ring shape, and the smoke inlets are opened obliquely downward.

[0011] In some embodiments, a motor cover is fixedly installed inside the tower body at a position corresponding to the driving motor.

[0012] In some embodiments, a movable plate is movably installed inside the air intake pipe, a movable rod is fixedly installed on the movable plate, the movable rod penetrates the side wall of the air intake pipe, and a return spring is sleeved on the movable rod.

[0013] Compared with the prior art, the present invention has the following significant advantages:

[0023] The utility model provides a simple SDS desulfurization tower device through improvement. The technical solution of the utility model is:

[0024] like Figure 1 and Figure 4As shown, a simple SDS desulfurization tower device comprises a tower body 1, which is a hollow cylindrical structure. An air inlet pipe 2 is fixedly installed on the upper side wall of the tower body 1, and the air inlet pipe 2 is a cylindrical structure. The air inlet pipe 2 is connected to the interior of the tower body 1. A discharge pipe 3 connected to the interior of the tower body 1 is fixedly installed at the bottom of the tower body 1, and the discharge pipe 3 is a cylindrical pipe. A support leg 4 is fixedly installed at the bottom of the tower body 1, and the support leg 4 is a cylindrical structure. A smoke inlet seat 5 is fixedly installed at the position of the interior of the tower body 1 corresponding to the air inlet pipe 2. The smoke seat 5 is a hollow circular ring structure, the smoke inlet seat 5 is connected to the inside of the air inlet pipe 2, and a plurality of smoke inlets 6 are evenly distributed in a ring shape on the inner wall of the smoke inlet seat 5. The smoke inlet 6 is a circular hole, and the smoke inlet 6 is opened obliquely downward. A liquid storage tank 7 is fixedly installed on the top of the tower body 1. The liquid storage tank 7 is a hollow cylindrical structure. A water pump 8 is arranged inside the liquid storage tank 7. A liquid inlet pipe 10 is fixedly installed on the input end of the water pump 8. A connecting pipe 9 is fixedly installed on the output end of the water pump 8. The connecting pipe 9 is a hollow cylindrical structure. The structure is as follows: a drain pipe 11 is movably installed at the bottom of the connecting pipe 9. The drain pipe 11 is a hollow cylindrical structure. The drain pipe 11 is connected to the inside of the connecting pipe 9. A nozzle 12 is installed at the bottom of the drain pipe 11. The nozzle 12 is arranged obliquely upward. The interior of the liquid storage tank 7 is filled with absorbent. The smoke is sent into the interior of the smoke inlet seat 5 through the air inlet pipe 2. The smoke inlet seat 5 is provided with a smoke inlet port 6. The multiple smoke inlet ports 6 spray the smoke downward into the interior of the tower body 1. At the same time, the water pump 8 inside the liquid storage tank 7 is started, and the water pump 8 pumps the inside of the liquid storage tank 7. The absorption liquid is sent into the interior of the nozzle 12 through the connecting pipe 9 and the discharge pipe 11, and the nozzle 12 can spray the absorption liquid obliquely upward, so that the absorption liquid is mixed with the flue gas, and the absorbent reacts with the sulfur dioxide in the flue gas, thereby completing the desulfurization. A drawer 15 is movably installed on the side wall of the tower body 1, and a sieve plate 16 is fixedly installed on the drawer 15. The sieve plate 16 can screen the reactants, and the solids remain on the sieve plate 16, while the liquid is discharged from the interior of the tower body 1 through the discharge pipe 3. A cleaning mechanism is arranged inside the tower body 1;

[0025] The cleaning mechanism includes a connecting rod 13, a cleaning brush 14, a transmission gear ring 17, a driving motor 18 and a transmission gear 19. The connecting rod 13 is a cylindrical structure. The connecting rod 13 is fixedly mounted at the bottom of the nozzle 12. The cleaning brush 14 is fixedly mounted at the bottom of the connecting rod 13. The cleaning brush 14 fits the sieve plate 16. The transmission gear ring 17 is fixedly sleeved on the top of the side wall of the discharge pipe 11. The driving motor 18 is fixedly mounted on the top wall inside the tower body 1. The transmission gear 19 is fixedly mounted on the output end of the driving motor 18. The transmission gear 19 and the transmission gear ring 17 are meshed with each other. During desulfurization, the drive motor 18 can be started, and the drive motor 18 drives the transmission gear 19 to rotate, and the transmission gear 19 is meshed with the transmission gear ring 17, and the transmission gear ring 17 is then driven to rotate, which can drive the drain pipe 11 to rotate, and the drain pipe 11 drives the nozzle 12 to rotate. The rotation of the nozzle 12 can increase the spraying range of the absorption liquid, thereby increasing the reaction time of the absorption liquid and the flue gas, thereby improving the desulfurization effect. At the same time, the nozzle 12 drives the connecting rod 13 and the cleaning brush 14 to rotate, and the rotation of the cleaning brush 14 can clean the screen plate 16, thereby avoiding the blockage of the screen plate 16.

[0026] like Figure 2 and Figure 4 As shown, in one embodiment, a motor cover 20 is fixedly installed inside the tower body 1 at a position corresponding to the driving motor 18 , and the motor cover 20 can seal the driving motor 18 to protect the driving motor 18 .

[0027] like Figure 3 As shown, in one embodiment, a movable plate 21 is movably installed inside the air inlet pipe 2, and the movable plate 21 is a circular plate with the same size as the inside of the air inlet pipe 2. The movable plate 21 can seal the air inlet pipe 2 and the smoke inlet seat 5. A movable rod 22 is fixedly installed on the movable plate 21. The movable rod 22 is a cylindrical structure. The movable rod 22 penetrates the side wall of the air inlet pipe 2. A reset spring 23 is sleeved on the movable rod 22. When the air inlet pipe 2 transports smoke, the smoke will first push the movable plate 21, so that the movable plate 21 leaves the connection between the air inlet pipe 2 and the smoke inlet seat 5. Only then can the smoke enter the interior of the smoke inlet seat 5. When the smoke stops being transported, the movable plate 21 will be reset under the action of the reset spring 23, thereby sealing the air inlet pipe 2 to prevent the smoke from flowing back out of the tower body 1.

[0028] The specific working methods are:

[0029] The flue gas is sent into the interior of the smoke inlet seat 5 through the air inlet pipe 2. The smoke inlet seat 5 is provided with a smoke inlet port 6. The multiple smoke inlet ports 6 spray the flue gas downward into the interior of the tower body 1. At the same time, the water pump 8 in the liquid storage tank 7 is started. The water pump 8 sends the absorption liquid in the liquid storage tank 7 into the interior of the nozzle 12 through the connecting pipe 9 and the discharge pipe 11. The nozzle 12 can spray the absorption liquid obliquely upward, so that the absorption liquid is mixed with the flue gas, and the absorbent reacts with the sulfur dioxide in the flue gas, thereby completing the desulfurization. A drawer 15 is movably installed on the side wall of the tower body 1, and a sieve plate 16 is fixedly installed on the drawer 15. The sieve plate 16 can screen the reactants, and the solids remain on the sieve plate 16, while the liquid passes through the discharge pipe 3 is discharged from the interior of the tower body 1. At the same time, through the setting of the cleaning mechanism, when desulfurization is carried out, the driving motor 18 can be started, and the driving motor 18 drives the transmission gear 19 to rotate, and the transmission gear 19 is meshed with the transmission gear ring 17, and the transmission gear ring 17 is then driven to rotate, and then the drainage pipe 11 can be driven to rotate, and the drainage pipe 11 drives the nozzle 12 to rotate. The rotation of the nozzle 12 can increase the spraying range of the absorption liquid, thereby increasing the reaction time of the absorption liquid and the flue gas, thereby improving the desulfurization effect. At the same time, the nozzle 12 drives the connecting rod 13 and the cleaning brush 14 to rotate, and the rotation of the cleaning brush 14 can clean the screen plate 16, thereby avoiding the blockage of the screen plate 16.
