Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization and denitration, and particularly relates to an exhaust gas water replenishing device, a lime slaking tank and a lime pulping system. Background Art

[0002] The lime slaking tank in the desulfurization and denitration pulping system is mainly used for receiving lime and water, and stirring and mixing them in the tank to make lime slurry with a specific concentration.

[0003] Please refer to Figure 1 , Figure 1 which schematically shows a structural diagram of a lime pulping system provided by the prior art. As Figure 1 shown, the lime pulping system includes a lime bin 1 and a lime slaking tank connected to the lime bin 1; a stirrer 21, an exhaust pipe 22, a water inlet pipe 23 and a blanking pipe 24 are arranged at the top of the tank body 2 of the lime slaking tank, and the lime bin 1 is connected to the lime slaking tank through the blanking pipe 24; an overflow pipe 25 is arranged in the upper middle part of the side wall of the tank body 2, and a discharge pipe 26 is arranged in the lower part of the side wall; a bottom discharge pipe 27 is arranged at the bottom of the tank body 2. When the lime slaking tank works, industrial water is replenished into the tank body 2 from the water inlet pipe 23, lime is fed into the tank body 2 from the lime bin 1, and a large amount of hot gas and dust generated during the lime slaking process are discharged from the exhaust pipe 22.

[0004] However, a large amount of dust is directly discharged into the air, which is easy to pollute the environment. In addition, after the dust is discharged from the exhaust pipe 22 for a period of time, it will accumulate on the inner wall of the exhaust pipe 22, resulting in the blockage of the exhaust pipe 22. If the exhaust pipe 22 is completely blocked, a large amount of hot gas and dust cannot be discharged from the exhaust pipe 22, and will be ejected from the blanking pipe 24 in reverse, which is easy to block the blanking pipe 24, resulting in the inability of lime to be fed, thus affecting the pulping efficiency and further causing the interruption of lime slurry production. If no new lime slurry is replenished in the lime supply tank, there will be a risk of exceeding the standard of sulfur dioxide concentration at the outlet of the coke oven flue gas.

[0032] Embodiment 1

[0033] This embodiment provides an exhaust gas makeup water device for a reaction device to be exhausted and replenished with water (exemplarily, such as the lime digestion tank shown below Figure 7 ). Specifically, please refer to Figures 2 to 6 ,Figure 2 One specific example diagram of the exhaust gas water replenishing device provided in this embodiment; Figure 3 Schematic structural diagram of the exhaust gas filtering assembly and the exhaust gas water replenishing pipeline connected in this embodiment; Figure 4 Schematic structural diagram of the filtering element provided in this embodiment; Figure 5 Another specific example diagram of the exhaust gas water replenishing device provided in this embodiment; Figure 6 Another specific example diagram of the exhaust gas water replenishing device provided in this embodiment. As can be seen, Figures 2 to 6 the exhaust gas water replenishing device 3 includes an exhaust gas water replenishing pipeline 31 connected to the reaction device, and an exhaust gas filtering assembly 32 and a water replenishing assembly 33 connected to the exhaust gas water replenishing pipeline 31; the exhaust gas filtering assembly 32 includes an exhaust pipe 321 and a filtering element 322, the exhaust pipe 321 is used for discharging the waste gas in the reaction device, and the filtering element 322 is used for filtering impurities in the waste gas; the water replenishing assembly 33 is configured to transport water to the reaction device through the exhaust gas filtering assembly 32 and the exhaust gas water replenishing pipeline 31. Thus, for the exhaust gas water replenishing device 3 provided in this embodiment, by connecting the exhaust gas water replenishing pipeline 31 to the reaction device to be exhausted and replenished with water, the exhaust gas water replenishing pipeline 31 can be used to exhaust and replenish water to the reaction device simultaneously. By connecting the exhaust gas filtering assembly 32 to the exhaust gas water replenishing pipeline 31, the exhaust gas filtering assembly 32 includes an exhaust pipe 321 and a filtering element 322. Through the exhaust pipe 321, the waste gas in the reaction device can be discharged, and at the same time, through the filtering element 322, impurities in the waste gas can be filtered, thereby being able to better protect the environment. Further, by connecting the water replenishing assembly 33 to the exhaust gas water replenishing pipeline 31 and transporting water to the reaction device through the exhaust gas filtering assembly 32 and the exhaust gas water replenishing pipeline 31, the exhaust gas filtering assembly 32 and the exhaust gas water replenishing pipeline 31 can be flushed while replenishing water to the reaction device, thereby ensuring that the exhaust gas filtering assembly 32 and the exhaust gas water replenishing pipeline 31 can be more unobstructed.

[0034] It should be noted that the present utility model does not overly limit the type of the reaction device. For example, in some other embodiments, the reaction device can also be a desulfurized ash mixing tank.

[0035] Exemplarily, in one specific exemplary embodiment, the bottom of the exhaust water replenishing pipe 31 is used to connect to the reaction device, the water replenishing component 33 is connected to the top of the exhaust water replenishing pipe 31, and the exhaust pipe 321 is connected to the outer sidewall of the exhaust water replenishing pipe 31; a plug-in portion 323 is formed between the exhaust pipe 321 and the exhaust water replenishing pipe 31 to plug in the filter element 322. Thus, by connecting the bottom of the exhaust water replenishing pipe 31 to the reaction device, connecting the water replenishing component 33 to the top of the exhaust water replenishing pipe 31, and connecting the exhaust pipe 321 to the outer sidewall of the exhaust water replenishing pipe 31, the exhaust water replenishing device 3 can be installed on the reaction device more neatly, so that there is enough operating space left on the reaction device. By forming a plug-in portion 323 between the exhaust pipe 321 and the exhaust water replenishing pipe 31 to plug in the filter element 322, it is convenient to quickly replace the filter element 322, thereby improving the working efficiency of the reaction device; and it is convenient to maintain and clean the exhaust pipe 321 and the filter element 322.

[0036] Preferably, the exhaust pipe 321 is inclined and arranged on the outer sidewall of the exhaust water replenishing pipe 31, and the exhaust port 3211 of the exhaust pipe 321 is close to the water replenishing component 33; a support member 311 is arranged on the inner sidewall of the exhaust water replenishing pipe 31; the plug-in portion 323 is formed between the exhaust pipe 321 and the support member 311 to plug in the filter element 322. Thus, by arranging the exhaust pipe 321 inclinedly and the exhaust port 3211 of the exhaust pipe 321 being close to the water replenishing component 33, the exhaust pipe 321 can support the filter element 322; and by arranging the support member 311 on the inner sidewall of the exhaust water replenishing pipe 31 to support the filter element 322, the plug-in portion 323 can be formed between the exhaust pipe 321 and the support member 311 to plug in the filter element 322, thereby facilitating the staff to take and place the filter element 322. It should be noted that the present invention does not overly limit the inclination angle of the exhaust pipe 321 relative to the exhaust water replenishing pipe 31. Preferably, the inclination angle can be 45°.

[0037] Exemplarily, both the exhaust pipe 321 and the exhaust water replenishing pipe 31 are made of stainless steel, and the exhaust pipe 321 and the exhaust water replenishing pipe 31 are integrally formed, the exhaust port 3211 of the exhaust pipe 321 is rectangular; two screws are fixedly installed on the inner sidewall of the exhaust water replenishing pipe 31 as the support member 311 to support the filter element 322.

[0038] It should be noted that the above is only an exemplary illustration. The present utility model does not overly limit the specific connection positions of the exhaust gas filtering assembly 32 and the water replenishing assembly 33 on the exhaust gas and water replenishing pipeline 31, as long as the waste gas in the reaction device can be discharged after being filtered by the exhaust gas filtering assembly 32 to remove impurities, and the water replenishing assembly 33 can transport water into the reaction device through the exhaust gas filtering assembly 32 and the exhaust gas and water replenishing pipeline 31. For example, in some other embodiments, the top of the exhaust gas and water replenishing pipeline 31 is closed, and its bottom is used to connect to the reaction device. The exhaust pipe 321 and the water replenishing assembly 33 are both connected to the outer side wall of the exhaust gas and water replenishing pipeline 31. The connection position of the water replenishing assembly 33 on the outer side wall of the exhaust gas and water replenishing pipeline 31 is higher than the connection position of the exhaust pipe 321 on the outer side wall of the exhaust gas and water replenishing pipeline 31. An insertion portion 323 is formed between the exhaust pipe 321 and the exhaust gas and water replenishing pipeline 31 to insert the filter element 322, and the length direction of the water replenishing assembly 33 is perpendicular to the plane where the filter element 322 is located. For another example, in some other embodiments, the bottom of the exhaust gas and water replenishing pipeline 31 is used to connect to the reaction device. The water replenishing assembly 33 is connected to the top of the exhaust gas and water replenishing pipeline 31, the exhaust pipe 321 is connected to the outer side wall of the exhaust gas and water replenishing pipeline 31, and a filter element 322 is fixedly connected in the exhaust gas and water replenishing pipeline 31 through a flange (not shown in the figure). The filter element 322 is located between the exhaust pipe 321 and the reaction device.

[0039] Preferably, the filter element 322 includes a filter mesh support frame 3221 and a filter mesh 3222 installed on the filter mesh support frame 3221. Thus, the filter mesh support frame 3221 can help maintain the shape and stability of the filter mesh 3222, thereby ensuring the filtering effect of the filter element 322.

[0040] Exemplarily, when the exhaust gas and water replenishing pipeline 31 is cylindrical, one end of the filter mesh support frame 3221 is also set to be arc-shaped so that the filter element 322 can abut against the side wall of the exhaust gas and water replenishing pipeline 31, avoiding the generation of gaps between the filter element 322 and the side wall of the exhaust gas and water replenishing pipeline 31, thereby preventing the unfiltered escape of waste gas.

[0041] Furthermore, the mesh number of the filter mesh 3222 is not less than 80 and not higher than 120. Thus, it can filter the impurities in the waste gas and effectively discharge the filtered waste gas. Exemplarily, in one exemplary embodiment, the mesh number of the filter mesh 3222 is 100 meshes.

[0042] Preferably, a handle 3223 is provided on the filter mesh support frame 3221. Thus, it is convenient for the staff to take and place the filter element 322.

[0043] Furthermore, the water replenishing assembly 33 includes a water replenishing pipe 331 for communicating with a water supply device and a water replenishing valve 332 provided on the water replenishing pipe 331. One end of the water replenishing pipe 331 away from the water supply device is connected to the exhaust and water replenishing pipeline 31. Thus, the connection of the water replenishing pipe 331 with the water supply device lays a foundation for delivering water into the reaction device; by connecting one end of the water replenishing pipe 331 away from the water supply device to the exhaust and water replenishing pipeline 31, water can be delivered into the reaction device through the exhaust and water replenishing pipeline 31; and the water replenishing valve 332 can adjust the water volume so that water can stably enter the reaction device.

[0044] Preferably, one end of the water replenishing pipe 331 away from the water supply device extends into the exhaust and water replenishing pipeline 31 and is connected to a spray head 333, and the spray head 333 is located above the exhaust filtering assembly 32. Thus, the flushing area of the exhaust filtering assembly 32 and the exhaust and water replenishing pipeline 31 can be enlarged, so that the exhaust filtering assembly 32 and the exhaust and water replenishing pipeline 31 can be more unobstructed.
