Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of desulfurization, in particular to a desulfurization device with a shunt spraying structure. Background Art
[0002] Flue gas desulfurization refers to the process of removing sulfur oxides from flue gas or other industrial waste gases. Flue gas desulfurization is of great significance for environmental protection and industrial production. Through desulfurization treatment, the emission of sulfur dioxide generated in industrial production processes such as coal combustion can be reduced, thereby reducing the formation of acid rain, protecting the environment, and improving air quality.
[0003] Wet flue gas desulfurization is a technology that uses an aqueous solution or slurry of an alkaline substance as an absorbent to absorb sulfur dioxide in the flue gas and thus remove it from the flue gas. The most common wet flue gas desulfurization is to make a slurry by adding water to limestone powder as the absorbent and pump it into the device to fully contact and mix with the flue gas. Sulfur dioxide in the flue gas reacts with calcium carbonate in the slurry and the air blown in from the lower part of the device to generate calcium sulfate. After the calcium sulfate reaches a certain saturation, it crystallizes to form dihydrate gypsum.
[0004] In the existing technical solutions, when the flue gas is introduced, there will be a problem that the flue gas escapes without fully reacting with the solution in the device, resulting in insufficient desulfurization of the flue gas. Summary of the Invention
[0005] The purpose of the utility model is to provide a desulfurization device with a shunt spraying structure. Through the cooperation of a flow disturbance stirring component and a shunt spraying component, the flue gas staying in the reaction tank can be fully desulfurized, avoiding the situation that some flue gas escapes without fully reacting with the slurry in the device, thus solving the problem of insufficient desulfurization of the flue gas mentioned in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A desulfurization device with a shunt spraying structure, including a reaction tank, a flue gas injection pipe is fixedly installed at the middle position of the bottom end surface of the reaction tank, and a flue gas discharge pipe is fixedly installed at the middle position of the top end surface of the reaction tank;
[0007] A flow disturbance stirring component is jointly arranged inside and outside the reaction tank. The flow disturbance stirring component includes a driving motor fixedly installed on the front end surface of the reaction tank. The output end of the driving motor penetrates through the front end surface of the reaction tank and is fixedly connected with a transmission rod. Six flow disturbance vanes are arrayed on the outer wall of the transmission rod.
[0008] Preferably, the inside of the reaction tank is a cylindrical hollow structure, and the inside of the reaction tank is interconnected with the flue gas discharge pipe. The rear end of the reaction tank is hinged with a tank cover.
[0009] Preferably, the interior of the reaction tank is interconnected with the flue gas injection pipe, and a breathable and waterproof diaphragm is fixedly installed at the connection between the flue gas injection pipe and the reaction tank.
[0010] Preferably, a flow splitting and jetting assembly is provided both inside and outside the reaction tank, and the flow splitting and jetting assembly includes a delivery pump fixedly installed on the bottom end face of the reaction tank.
[0011] Preferably, both the input end and the output end of the delivery pump are communicated with delivery pipes. The input end of the rear delivery pipe extends into the interior of the reaction tank, and the output end of the front delivery pipe is communicated with a delivery sleeve.
[0012] Preferably, the delivery sleeve is rotatably sleeved on one end of the drive rod close to the drive motor. A communication channel is formed inside the drive rod, and communication holes are provided between the communication channel and the delivery sleeve.
[0013] Preferably, a plurality of flow splitting channels are formed inside the flow disturbing blades, and a plurality of flow splitting spray holes corresponding to the flow splitting channels are formed on the end faces of the flow disturbing blades. The flow splitting spray holes are interconnected with the communication channel through the flow splitting channels.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. Through the cooperation of the flow disturbing and stirring assembly and the flow splitting and jetting assembly, the present utility model can fully desulfurize the flue gas staying in the reaction tank, avoiding the situation where some flue gas escapes without fully reacting with the slurry in the device, thus causing the problem of insufficient flue gas desulfurization.
[0016] 2. The arrangement of a plurality of flow splitting spray holes in the present utility model can ensure the uniform distribution of the slurry in the device, avoiding the situation of too high or too low local concentration. This uniform distribution helps to optimize the reaction conditions, making the desulfurization reaction more stable and efficient. Through the cooperation of the spraying from the flow splitting spray holes and the high-speed rotating flow disturbing blades, the sprayed slurry can impact on the inner wall of the device, so that the desulfurizer slurry can be uniformly dispersed into fine droplets by high-speed impact, which can greatly increase the contact area and contact time between the slurry and the flue gas. This sufficient contact enables sulfur dioxide in the flue gas to be more effectively absorbed and reacted by the slurry, thereby improving the desulfurization efficiency.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] The present utility model provides a technical solution:
[0026] Please refer to Figures 1 to 3, A desulfurization device with a split spray structure, including a reaction tank 1. A flue gas injection pipe 2 is fixedly installed at the middle position of the bottom end surface of the reaction tank 1, and a flue gas discharge pipe 3 is fixedly installed at the middle position of the top end surface of the reaction tank 1; A turbulence stirring assembly 4 is provided inside and outside the reaction tank 1. The turbulence stirring assembly 4 includes a driving motor 401 fixedly installed on the front end surface of the reaction tank 1. The output end of the driving motor 401 penetrates the front end surface of the reaction tank 1 and is fixedly connected with a transmission rod 402. Six turbulence vanes 403 are arrayed on the outer wall of the transmission rod 402. The inside of the reaction tank 1 is a cylindrical hollow structure, and the inside of the reaction tank 1 is interconnected with the flue gas discharge pipe 3. A box cover is hinged to the rear end of the reaction tank 1, and the box cover is hermetically connected to the reaction tank 1. A filling pipe is connected to the box cover. The inside of the reaction tank 1 is interconnected with the flue gas injection pipe 2, and a breathable waterproof membrane 6 is fixedly installed at the connection between the flue gas injection pipe 2 and the reaction tank 1. The setting of the breathable waterproof membrane 6 can prevent the slurry in the reaction tank 1 from flowing into the flue gas injection pipe 2. A split spray assembly 5 is provided inside and outside the reaction tank 1.
[0027] By adopting the above technical solution, before use, limestone powder is made into slurry with water as an absorbent and filled into the reaction tank 1 through the filling pipe. At the same time, the box cover is closed tightly to ensure the sealing between the box cover and the reaction tank 1 to prevent slurry leakage, and it is necessary to ensure that the slurry submerges the upper port of the flue gas injection pipe 2. At this time, the flue gas is introduced into the reaction tank 1 through the flue gas injection pipe 2. In this way, when the flue gas is input, it will surely contact the slurry. By injecting the flue gas into the slurry, sulfur dioxide in the flue gas and the desulfurizer in the slurry; such as calcium carbonate in the limestone slurry, can fully contact and undergo a chemical reaction, thereby effectively removing sulfur dioxide from the flue gas. This structural setting can ensure the full mixing and reaction between the flue gas and the desulfurizer, thereby improving the desulfurization efficiency. And the desulfurizer in the slurry can continuously react with sulfur dioxide in the flue gas, thereby maintaining the stability of the reaction. This structural setting helps to reduce the volatility and uncertainty during the desulfurization process and improve the stability and reliability of the system. The flue gas overflowing from the slurry can disperse into the reaction tank 1. At this time, the driving motor 401 is started. The operation of the driving motor 401 can drive the transmission rod 402 to rotate, and the rotation of the transmission rod 402 can drive multiple turbulence vanes 403 to rotate. In this way, the turbulence vanes 403 can play a role in disturbing and dispersing the flue gas in the reaction tank 1, so that part of the flue gas can form a circulating flow in the cylindrical reaction tank 1, increasing the residence time of the flue gas in the reaction tank 1, and cooperating with the split spray assembly 5 to fully desulfurize the flue gas staying in the reaction tank 1, avoiding the situation that part of the flue gas escapes without fully reacting with the slurry in the device, thus causing the problem of insufficient flue gas desulfurization.
[0028] Specifically, such as Figures 2 to 4As shown in the figure, the shunt jet assembly 5 includes a delivery pump 501 fixedly installed on the bottom end surface of the reaction tank 1; both the input end and the output end of the delivery pump 501 are connected with a delivery pipe 502. The input end of the rear delivery pipe 502 extends into the interior of the reaction tank 1, and the output end of the front delivery pipe 502 is connected with a delivery sleeve 503; the delivery sleeve 503 is rotatably sleeved on one end of the drive rod 402 close to the drive motor 401. A communication channel 504 is provided inside the drive rod 402, and a communication hole 507 is provided between the communication channel 504 and the delivery sleeve 503; a plurality of shunt channels 505 are provided inside the spoiler blade 403, and a plurality of shunt spray holes 506 corresponding to the shunt channels 505 are provided on the end surface of the spoiler blade 403. The shunt spray holes 506 are interconnected with the communication channel 504 through the shunt channels 505.
[0029] By adopting the above technical solution, during use, start the delivery pump 501. When the delivery pump 501 works, it can pump out the slurry in the reaction tank 1 through the delivery pipe 502 and transport it to the delivery sleeve 503. The delivery sleeve 503 is interconnected with the communication channel 504 through the communication hole 507, so that the slurry can be transported into the communication channel 504. Through the connection between the communication channel 504 and each shunt channel 505, the slurry can be transported into each shunt channel 505, and then the slurry can be sprayed out through the shunt spray holes 506 of each shunt channel 505, thus realizing the shunt spraying effect of the slurry. The setting of a plurality of shunt spray holes 506 can ensure the uniform distribution of the slurry in the device and avoid the situation of too high or too low local concentration. This uniform distribution helps to optimize the reaction conditions and make the desulfurization reaction more stable and efficient. Through the cooperation of the spraying through the shunt spray holes 506 and the high-speed rotating spoiler blade 403, the sprayed slurry can be made to impact the inner wall of the device, so that the desulfurizer slurry can be evenly dispersed into fine droplets by high-speed impact, which can greatly increase the contact area and contact time between the slurry and the flue gas. This sufficient contact enables sulfur dioxide in the flue gas to be more effectively absorbed and reacted by the slurry, thereby improving the desulfurization efficiency.
[0030] Working principle: Before use, first make limestone powder into slurry by adding water through a filling pipe and fill it into the reaction tank 1 as an absorbent. At the same time, close the tight box cover to ensure the sealing between the box cover and the reaction tank 1 to avoid slurry leakage, and ensure that the slurry submerges the upper port of the flue gas filling pipe 2. At this time, introduce the flue gas into the reaction tank 1 through the flue gas filling pipe 2. In this way, when the flue gas is input, it will surely contact the slurry. By injecting the flue gas into the slurry, sulfur dioxide in the flue gas and the desulfurizer in the slurry can fully contact and undergo a chemical reaction, thereby effectively removing sulfur dioxide from the flue gas. The flue gas overflowing from the slurry can disperse into the reaction tank 1. At this time, start the drive motor 401. The operation of the drive motor 401 can drive the transmission rod 402 to rotate, and the rotation of the transmission rod 402 can drive multiple spoiler vanes 403 to rotate, so that the spoiler vanes 403 can have a spoiler and dispersion effect on the flue gas in the reaction tank 1, thereby enabling part of the flue gas to form a circulation in the cylindrical reaction tank 1 and increasing the residence time of the flue gas in the reaction tank 1.
[0031] Secondly, start the transfer pump 501. The operation of the transfer pump 501 can extract the slurry in the reaction tank 1 through the transfer pipe 502 and transport it into the transfer sleeve 503. The transfer sleeve 503 is interconnected with the communication channel 504 through the communication hole 507, so that the slurry can be transported into the communication channel 504. Through the connection between the communication channel 504 and each diversion channel 505, the slurry can be transported into each diversion channel 505, so that the slurry can be sprayed out through the diversion spray holes 506 of each diversion channel 505, thereby realizing the diversion spraying effect of the slurry. Through the cooperation between the spraying of the diversion spray holes 506 and the high-speed rotating spoiler vanes 403, the sprayed slurry can be made to impact the inner wall of the device, so that the desulfurizer slurry can be evenly dispersed into fine droplets by high-speed impact and react with the sulfides in the flue gas.
[0032] Finally, the flue gas after sufficient reaction can be discharged through the flue gas discharge pipe 3. When the desulfurization is completed, rotate and open the box cover, so that the reaction products in the reaction tank 1 can be taken out of the reaction tank 1, and the inside of the reaction tank 1 can be cleaned and maintained to facilitate subsequent desulfurization work.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
