Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flue gas treatment equipment, in particular to a flue gas desulfurization device. Background Technique
[0002] With the continuous advancement of the industrialization process, the sulfur dioxide content in the flue gas discharged by industrial enterprises such as coal-fired power plants and steel mills has increased year by year, causing serious pollution to the atmospheric environment. In order to reduce sulfur dioxide emissions and meet environmental protection requirements, desulfurization towers have been widely used. However, there are some deficiencies in the actual application of traditional desulfurization towers, such as uneven spraying, poor desulfurization effect in dead corners, etc., resulting in low desulfurization efficiency. Content of the Utility Model
[0003] The purpose of the utility model is to provide a flue gas desulfurization device to solve the problems put forward in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: a flue gas desulfurization device, including a tower body, an eliminator is fixedly installed at the top end inside the tower body, a shaft rod is rotatably installed in the middle of the eliminator, the bottom end of the shaft rod is connected with a spray plate, a support is fixedly installed in the middle inside the tower body, a spray disc is fixedly installed in the middle of the support, one side bottom end outside the tower body is connected with a first liquid pipe, and one end of the first liquid pipe is connected to the input end of a pump body.
[0005] When using a flue gas desulfurization device in this technical solution, the staff needs to externally power the present utility model first and control the operation of the present utility model through the control panel. The staff transfers the slurry for flue gas desulfurization to the inner bottom end of the tower body through the slurry inlet pipe. After transferring an appropriate amount, the valve of the slurry inlet pipe is closed. At this time, the staff turns on the pump body. The pump body pumps the slurry at the inner bottom end of the tower body into it through the first liquid pipe, and then transfers it to the inside of the tee pipe through the second liquid pipe. The tee pipe transfers the slurry to the inside of the third liquid pipe and the fourth liquid pipe respectively. The slurry entering the third liquid pipe will be directly transferred to the inside of the spray disc and sprayed out through the spray holes provided on the bottom surface of the spray disc. The slurry entering the fourth liquid pipe will be directly transferred to the inside of the shaft rod and transferred to the inside of the spray plate through the shaft rod, and sprayed out through the spray holes provided on the bottom surface of the spray plate. At this time, the staff starts the motor. The first bevel gear fixed to the rotating output end of the motor rotates, and the second bevel gear on the meshing surface of the first bevel gear rotates. The second bevel gear drives the shaft rod fixed in the middle to rotate. After the shaft rod rotates, the spray plate connected to its bottom end will rotate accordingly. In this way, the slurry sprayed out by the spray plate will be sprayed on the inner side surface of the tower body in a rotating manner. When the slurry flows down, the staff transfers the flue gas to be desulfurized to the inside of the tower body through the air inlet pipe. After the flue gas is transferred to the inside of the tower body, it will be spray-desulfurized by the slurry sprayed down by the spray disc and the spray plate. The desulfurized flue gas will pass through the inside of the demister. The demister can remove the slurry entrained in the flue gas. Finally, the flue gas is discharged through the exhaust pipe. When the slurry inside the present utility model needs to be replaced, the staff opens the valve of the slurry discharge pipe and discharges the slurry at the inner bottom end of the tower body through the slurry discharge pipe.
[0006] Preferably, the output end of the pump body is connected with a second liquid pipe, and one end of the second liquid pipe is connected with a tee pipe. Through the cooperation of the first liquid pipe, the pump body, the second liquid pipe and the tee pipe, the slurry at the inner bottom end of the tower body can be conveyed to the inside of the third liquid pipe and the fourth liquid pipe.
[0007] Preferably, one side of the tee pipe is connected with a third liquid pipe, and one end of the third liquid pipe is connected to the outer top surface of the spray disc. The installation of the third liquid pipe enables the slurry transferred by the tee pipe to be conveyed to the inside of the spray disc through this pipe, achieving the conveying effect.
[0008] Preferably, the top end of the tee pipe is connected with a fourth liquid pipe, and one end of the fourth liquid pipe is connected to the surface of the rotary joint, and the rotary joint is arranged at the top end of the shaft rod. The installation of the fourth liquid pipe enables the slurry transferred by the tee pipe to be conveyed to the inside of the spray plate through this pipe, achieving the conveying effect. The installation of the rotary joint enables the fourth liquid pipe to convey the slurry to the inside of the shaft rod, and when the shaft rod rotates, it will not drive the fourth liquid pipe to rotate, playing the role of separating the rotational force and not affecting the slurry conveyance.
[0009] Preferably, one end of the outer top surface of the tower body is fixed with a box body, a motor is fixed inside the box body, a first bevel gear is fixed to the output end of the motor, a second bevel gear is meshed with the surface of the first bevel gear, and the second bevel gear is fixed to the side of the top end of the shaft rod. Through the cooperation of the motor, the first bevel gear and the second bevel gear, the shaft rod can rotate, achieving the effect of power output and transmission.
[0010] Preferably, the other end of the outer top surface of the tower body is connected with an exhaust pipe, the outer bottom surface of the tower body is fixed with a base, and the middle of the other side of the tower body is connected with an intake pipe. Through the cooperation of the intake pipe and the exhaust pipe, the flue gas to be desulfurized can be transported into the tower body and the desulfurized flue gas can be discharged from the tower body, achieving the effect of input and output. The installation of the base enables the utility model to be stably placed and used.
[0011] Preferably, the middle of the outer front surface of the tower body is connected with a slurry inlet pipe, the bottom end of the outer rear surface of the tower body is connected with a slurry discharge pipe, and valves are arranged in both the slurry discharge pipe and the slurry inlet pipe. Through the cooperation of the slurry inlet pipe, the slurry discharge pipe and the valves, the slurry for treating the flue gas can enter and exit the inside of the tower body, achieving the effect of switching input and output.
[0012] Preferably, the interiors of both the spray plate and the spray disc are designed with a cavity structure, and spray holes are arranged at both ends of the bottom surface of the spray plate and the bottom surface of the spray disc. The design of the cavity structure enables the slurry in the third liquid pipe and the shaft rod to be transported into their interiors and sprayed out through the spray holes.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] 1. The utility model is provided with a rotary spraying system, which is composed of a rotating spray plate and a fixed spray disc. The spray disc is installed in the middle inside the tower body to spray and desulfurize the flue gas in the middle inside the tower body, while the spray holes opened at both ends of the bottom surface of the spray plate can spray slurry on the inner sides of the tower body. The rotary spraying makes the slurry evenly distributed in all corners inside the tower body, preventing the flue gas from escaping from dead corners and significantly improving the desulfurization efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] Embodiment 1
[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a flue gas desulfurization device proposed by the present invention includes a tower body 2.

The bottom end of the shaft rod 11 is connected to a spraying plate 13. A support 14 is fixedly installed in the middle inside the tower body 2. A spraying disc 15 is fixedly installed in the middle of the support 14. One side bottom end outside the tower body 2 is connected to a first liquid pipe 3. One end of the first liquid pipe 3 is connected to the input end of a pump body 4.
[0023] The staff transfers the slurry for flue gas desulfurization to the inner bottom end of the tower body 2 through the slurry inlet pipe. After transferring an appropriate amount, the valve of the slurry inlet pipe is closed. At this time, the staff turns on the pump body 4. The pump body 4 pumps the slurry at the inner bottom end of the tower body 2 into it through the first liquid pipe 3, and then transfers it to the inside of the tee pipe 6 through the second liquid pipe 5. The tee pipe 6 transfers the slurry to the inside of the third liquid pipe 8 and the fourth liquid pipe 7 respectively. The slurry entering the third liquid pipe 8 will be directly transferred to the inside of the spray disc 15 and sprayed out through the spray holes provided on the bottom surface of the spray disc 15.

At this time, the staff starts the motor 20. The motor 20 rotates the first bevel gear 19 fixed to the output end. The first bevel gear 19 rotates the second bevel gear 18 on the meshing surface. The second bevel gear 18 drives the shaft rod 11 fixed in the middle to rotate. After the shaft rod 11 rotates, the spray plate 13 connected to its bottom end will rotate accordingly. In this way, the slurry sprayed out by the spray plate 13 will be sprinkled on the inner side surface of the tower body 2 in a rotating manner. When the slurry flows down, the staff transfers the flue gas to be desulfurized to the inside of the tower body 2 through the air inlet pipe 16. After the flue gas is transferred to the inside of the tower body 2, it will be spray-desulfurized by the slurry sprayed down by the spray disc 15 and the spray plate 13. The desulfurized flue gas will pass through the inside of the demister 12. The demister 12 can remove the slurry entrained in the flue gas. Finally, the flue gas is discharged through the exhaust pipe 10. When the slurry inside the present utility model needs to be replaced, the staff opens the valve of the slurry discharge pipe and discharges the slurry at the inner bottom end of the tower body 2 through the slurry discharge pipe.
