Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization tower recovery equipment, in particular to a desulfurization tower gypsum recovery system. Background Art

[0002] In the production process of ceramics, the flue gas of ceramic kilns contains a large amount of sulfur oxides. Before it is discharged, it must be desulfurized in a desulfurization tower to meet the emission standards. The flue gas of ceramic kilns is generally desulfurized by the limestone method. After desulfurization, a large amount of gypsum water waste liquid will be produced. When the gypsum water flows into the environmental protection pool and the raw material warehouse, it will pollute the environmental protection water and raw materials and cause the bricks to bubble. The traditional method uses natural precipitation to precipitate into gypsum slurry, and then pour the gypsum slurry into the stacking pool. However, the gypsum slurry precipitated by the natural precipitation method still contains a high amount of water, which is difficult to handle and difficult to stack high, resulting in gypsum slurry all over the ground.

[0003] The desulfurization tower gypsum recovery device in the prior art usually uses an oscillator to separate solid and liquid. Its working principle is as follows: Figure 1 As shown, it includes multiple sedimentation tanks, and an oscillator is set on the side wall of the sedimentation tank. The gypsum wastewater and gypsum in the sedimentation tank are separated by the oscillation. The gypsum is naturally precipitated to the bottom of the pool to form gypsum cakes under the action of the oscillation. The gypsum wastewater is discharged after being filtered through the multi-stage sedimentation tank; however, Figure 1 The desulfurization tower gypsum recovery system also has the following problems:

[0004] (1) Due to the lack of a dosing device, the gypsum in the sedimentation tank can only naturally settle to the bottom of the pool under the action of the oscillator. This method not only has a slow sedimentation speed, but also easily causes the gypsum to disperse during the oscillation process, thereby aggravating the turbidity of the gypsum wastewater.

Greater than, less than, and more than are understood to exclude the number itself, and above, below, and within are understood to include the number itself. If there is a description of the first, second, and third, it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] The following is combined with Figure 1-5 , an embodiment of a desulfurization tower gypsum recovery system of the utility model is further described in detail.

[0031] A desulfurization tower gypsum recovery system, such as Figure 2 , 3 As shown, it includes a base bracket 1, a sedimentation box 2 installed on the base bracket 1, a dosing device 3 is suspended on the sedimentation box 2, the dosing device 3 includes a medicine storage box 31 and a spray head 32, a hook 33 is integrally formed on one side of the medicine storage box 31, and the medicine storage box 31 is suspended on the side wall of the sedimentation box 2 through the hook 33, a medicine adding port 35 is opened on the top of the medicine storage box 31, the spray head 32 is connected to the medicine storage box 31, and a plurality of spray holes 321 are opened on the spray head 32; a medicine sensor 35 for real-time detection of the remaining medicine is also installed on the medicine storage box 31, and the medicine sensor 34 is connected to the external electronic equipment signal.

[0032] Specifically, medicine is placed in the medicine storage box 31, and the medicine can react with gypsum in gypsum wastewater to form a precipitate. There are many types of medicines to choose from, such as sodium carbonate powder. The principle is to use a chemical reaction. Sodium carbonate reacts with gypsum wastewater to form a white precipitate, and at the same time clarifies the gypsum wastewater. As long as it can react with gypsum to form a precipitate, the medicine is not limited; a dosing port 35 is provided at one end of the medicine storage box 31, and the medicine can be supplemented along the dosing port 35. At the same time, a cover plate 36 is provided at the top of the medicine storage box 31, and a plurality of hollow holes 361 are evenly provided on the top of the cover plate 36. When the gypsum wastewater is fully stored, it can flow into the medicine storage box 31 through the hollow hole 361 for reaction; in addition, the spray head 32 is installed on the medicine storage box 31, and a plurality of spray holes 321 are opened on the spray head 32. The spray head 32 can spray the sodium carbonate powder in the medicine storage box 31 into the gypsum wastewater. In order to remind the operator of the remaining medicine in the medicine storage box 31, the medicine sensor 34 arranged on the spray head 32 can detect the remaining medicine in real time and provide feedback. The medicine sensor 34 can synchronize the data with the electronic device, so that the operator can remotely monitor or control the discharge of the medicine.

[0033] In this embodiment, the oscillating device includes an oscillator, which is used to vibrate the sedimentation box for solid-liquid separation, and the oscillator is fixed to the bottom end of the mounting guard plate by welding.

[0034] Specifically, the oscillator 6 uses a vibration motor to vibrate, and a vibration transmission rod is transmission-connected to the output shaft of the vibration motor, and the other end of the vibration transmission rod is connected to the sedimentation box 2, thereby transmitting the vibration force to the sediment in the sedimentation box 2; wherein, the working principle of the oscillator 6 is: when the solid particles in the sedimentation box 2 are suspended in the liquid, the vibration force generated by the oscillator 6 is transmitted to the sediment through the vibration transmission rod, causing it to vibrate slightly, thereby promoting collision and sedimentation between the solid particles. This vibration effect can effectively improve the sedimentation efficiency and shorten the sedimentation time.

[0035] It is worth noting that the installation position of the oscillator 6 in the present invention is subject to corresponding requirements. If it is installed at the bottom, the vibration force can be uniform, so that the vibration force in all directions inside the sedimentation box 2 is uniform. If it is installed on the side wall of the sedimentation box 2, the vibration force on one side of the sedimentation box 2 close to the oscillator 6 is much greater than that on the other side, which leads to slow sedimentation efficiency and poor sedimentation effect.

[0036] In this embodiment, an installation guard plate 5 is arranged between the base bracket 1 and the sedimentation box 2, and baffles 52 for limiting the position of the sedimentation box 2 are arranged on the four edges of the installation guard plate 5, so that an installation groove 51 adapted to the sedimentation box 2 is formed in the middle, and the sedimentation box 2 is placed in the installation groove 51; a shock absorbing device 4 is arranged at the connection between the installation guard plate and the base bracket 1, and the two ends of the shock absorbing device 4 are respectively fixedly connected to the base bracket 1 and the installation guard plate 5.

[0037] Specifically, the base bracket 1 is used to support the installation of the sedimentation box 2 to prevent the sedimentation box 2 from shaking and shifting during vibration, which may cause the risk of falling. An installation guard plate 5 is set on the bottom bracket 1, and the sedimentation box 2 is placed on the installation guard plate 5. The sedimentation box 2 and the installation guard plate 5 are installed in a detachable manner. The purpose is to facilitate the cleaning of solid matter accumulated in the sedimentation box 2 after sedimentation is completed, and the baffles 52 set around the installation guard plate 5 can effectively limit the position of the sedimentation box 2.

[0038] In this embodiment, if Figure 4 , 5 As shown, shock absorbing devices 4 are arranged at the four corners of the top of the base bracket 1, one end of the shock absorbing device 4 is fixedly connected to the base bracket 1, and the other end is connected to the mounting guard plate 5; the shock absorbing device 4 includes a shock absorbing spring 41, a damping member 42 and a buffer block 43, the buffer block 43 is respectively arranged on the base bracket 1 and the mounting guard plate 5, and the buffer block 43 is a hollow structure, the damping member 42 is connected to the buffer block 43, and the two ends of the damping member 42 are respectively abutted on the base bracket 1 and the mounting guard plate 5, and the shock absorbing spring 41 is sleeved on the outside of the damping member 42.

[0039] Specifically, in order to avoid the risk of the entire sedimentation box 2 shaking and swinging simultaneously under the action of the oscillator 6 during the oscillation of the oscillator 6, which may cause displacement and fall, the utility model arranges a shock absorbing device 4 on the base bracket 1, utilizes elastic force to absorb the force generated in the vibration process, and utilizes the damping member 42 to generate a reverse force opposite to the vibration force, thereby canceling the vibration force, so that the sedimentation box 2 always remains stable. In order to further improve the buffering effect, the buffer blocks 43 arranged at both ends of the shock absorbing spring 41 can buffer and absorb the vibration force to avoid displacement of the sedimentation box 2, thereby effectively improving the sedimentation efficiency of the sedimentation box 2.

[0040] In this embodiment, the sedimentation tank 2 includes a primary sedimentation tank 21, a secondary sedimentation tank 22 and an N-stage sedimentation tank, N is a positive integer greater than or equal to 2, and the tops of the multiple sedimentation tanks 2 are respectively connected to the output end of the desulfurization tower; and the multiple sedimentation tanks 2 are arranged in sequence from high to low to form a ladder shape, and the end of the sedimentation tank 2 is connected to the waste liquid recovery tank 24; two adjacent sedimentation tanks 2 are connected through an overflow pipe 7, one end of the overflow pipe 7 is connected to the top outlet of the upper-stage sedimentation tank 2, and the other end is connected to the upper part of the lower-stage sedimentation tank 2; the bottom of the sedimentation tank 2 is provided with a strip through hole 8 that is convenient for forklift transportation, and there are at least two strip through holes 8, and the cross-section of the strip through holes 8 is a rectangular structure

[0041] Specifically, in industrial production, the sedimentation tank 2 is widely used in the solid-liquid separation process to separate the solid particles suspended in the liquid through natural sedimentation. However, due to the difference in density and size of solid particles, the sedimentation efficiency is low and the time is long. Therefore, multiple sedimentation boxes 2 are set for filtering and sedimentation to improve the sedimentation efficiency. The sedimentation boxes 2 in the utility model can be set in corresponding quantity according to actual needs. Taking three sedimentation boxes 2 as an example, from left to right, they are respectively a first-level sedimentation box 21, a second-level sedimentation box 22, and a third-level sedimentation box 23. At this time, N is equal to 3, and each level of sedimentation boxes 2 are connected through an overflow pipe 7. A switch valve is provided in the overflow pipe 7. The switch valve is used to control the flow between two adjacent sedimentation boxes 2. Since the height of each sedimentation box 2 is different, the concentration of the precipitated gypsum wastewater is also different. After step-by-step sedimentation and filtration, the last sedimentation box 2 is connected to the waste liquid recovery box 24, and the wastewater flows into the waste liquid recovery box 24. The precipitated gypsum is located at the bottom of the sedimentation box 2 to form a solid. A forklift can be used to insert the bar through hole 8 provided at the bottom of the sedimentation box 2 to replace the sedimentation box 2 and recover the sediment.

[0042] The working principle of this utility model:

[0043] When filtering and separating the lime slurry produced by the desulfurization tower, the desulfurization tower is used to add lime to treat the sulfur oxides in the flue gas of the ceramic kiln. The treated gypsum water is filtered by the graded filter on the desulfurization tower and then flows to the corresponding sedimentation tanks 2. Different levels of sedimentation tanks 2 process gypsum water with different initial concentrations. In order to increase the processing capacity of the gypsum water in the desulfurization tower, the sedimentation tank 2 is vibrated by an oscillator 6 arranged at the bottom of the sedimentation tank 2. The sedimentation efficiency of the gypsum is accelerated under the action of the vibration. At the same time, the drug is sprayed by the dosing device 3 to combine with the solids in the gypsum wastewater and precipitate to the bottom of the box. After a period of vibration, the gypsum slurry in the sedimentation tank 2 of this level flows to the sedimentation tank 21 of the next level, and in the next The gypsum slurry is vibrated and precipitated in the N-stage sedimentation box 21, and so on. After multiple stages of vibration sedimentation, the high-concentration gypsum slurry precipitated in the N-stage sedimentation box 2 is finally divided into fixed gypsum and wastewater, and the wastewater flows into the waste liquid recovery box 24. The desulfurization tower gypsum recovery system of the utility model filters and recovers gypsum by setting a multi-stage sedimentation box 2, and sets an oscillator 6 at the bottom of the multi-stage sedimentation box 2 to accelerate solid-liquid separation, thereby improving the sedimentation efficiency; at the same time, a dosing device 3 is set on the sedimentation box 2 to realize automatic drug delivery, and a drug sensor 34 is used to detect the drug inventory in real time and automatically deliver it in a quantitative manner, so that it reacts with the gypsum wastewater to accelerate gypsum precipitation. Since the precipitation time is reduced, production time and energy consumption can also be saved, thereby reducing production costs.

[0044] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
