Description

Technical Field

[0001] The present invention generally relates to the technical field of stirring and mixing, and in particular to a mixing device for producing a granular desulfurizing agent and a production process thereof. Background Art

[0002] Desulfurizer generally refers to the agent for removing free sulfur or sulfur compounds from fuel, raw materials or other materials; in the control and treatment of pollutants, it mainly refers to the agent used to remove sulfur oxides (including SO2 and SO3) from exhaust gas. This mixed solution desulfurizer has surface activity and catalytic oxidation, which can promote the direct reaction of SO2, accelerate the dissolution of CaCO3, promote the rapid oxidation of CaSO3 to CaSO4, strengthen the precipitation of CaSO4, reduce the liquid-gas ratio, reduce the calcium-sulfur ratio, and reduce the evaporation of water.

[0003] The preparation methods of desulfurizers mainly include chemical synthesis, physical mixing, and specific process flows, among which physical mixing is a relatively simple preparation process, such as the preparation of zinc oxide desulfurizers, which adopts dry mixing, precipitation or sol-gel methods. In the preparation process, mixing equipment is used more frequently, and the raw materials need to be placed in a reactor, mixed and stirred, and then relevant solutes or solvents are added, or precipitation is performed to form the final desulfurizer.

[0004] During the mixing process, some materials will settle under the action of gravity and accumulate at the bottom of the reactor. Even if there are stirring blades at the bottom, during the flow of liquid, the sediment will flow to the side of the reactor under the action of centrifugal force, making it impossible to achieve uniform mixing. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, according to the present invention, a mixing device for producing particulate desulfurizer is provided, comprising: a kettle body, a bottom stirring device is arranged at the bottom of the kettle body, and the bottom stirring device comprises a bottom rotating shaft, which is coaxially arranged at the bottom of the kettle body and is sealed and rotatably connected with the bottom wall of the kettle body; a support capsule, which is connected to one side of the bottom rotating shaft; and a stirring capsule, which is wrapped around the outside of the support capsule and is rotatably connected with the support capsule, a gap is left between the stirring capsule and the peripheral side of the stirring capsule is opened with a plurality of through holes; a driving component for driving the bottom rotating shaft to rotate around its axis is arranged at the bottom of the kettle body; a channel is arranged at the bottom of the bottom rotating shaft and is interconnected with the inside of the stirring capsule for introducing gas or liquid. Through the above-mentioned technical features, the driving component drives the bottom rotating shaft to rotate, so that the stirring bag can achieve the effect of stirring the sediment at the bottom of the kettle body, and while the stirring bag is stirring, high-pressure gas or liquid is introduced into the bottom rotating shaft, so that the gas or liquid is discharged through the through hole of the stirring bag at a high speed, which has the effect of disturbing the surrounding sediment and fully stirring it. Combined with the rotation of the stirring bag, not only the range of disturbance is expanded, but also the impact of the gas or liquid discharged from the through hole on the sediment accelerates the dissolution of the sediment, and as the bubbles rise, it will also drive the flow of the solution, further improving the mixing efficiency of the sediment.

[0006] In some embodiments, the inner wall of the stirring capsule is provided with a plurality of guide vanes for disturbing the gas or liquid and driving the stirring capsule to rotate around the supporting capsule. Thus, due to the gap between the supporting capsule and the stirring capsule, the flow direction of the gas or liquid is restricted. With the impact of the gas or liquid on the guide vane, the stirring capsule itself is driven to rotate, and the flow range of the gas or liquid discharged from the through hole of the stirring capsule is made wider, the stirring and mixing efficiency of the sediment is higher, and the rotation of the stirring capsule is achieved only by setting the guide vane, thereby saving energy consumption.

[0007] In some embodiments, the support capsule is connected to the bottom rotating shaft via a connecting rod, and a spoiler impact plate is rotatably connected to the connecting rod, and a gap is left between the spoiler impact plate and the stirring capsule. Therefore, as the bottom rotating shaft rotates, the spoiler impact plate will also swing on the connecting rod, and since there is a gap between the spoiler impact plate and the stirring capsule, the sediment will flow into the gap between the spoiler impact plate and the stirring capsule, and as the gas or liquid passes through the through hole of the stirring capsule at high speed, the gas or liquid impacts the inner wall of the spoiler impact plate, and the impact force is greater, and the effect is greater, thereby playing the role of impacting and breaking up the sediment, and further improving the dissolution efficiency of the sediment.

[0008] In some embodiments, the spoiler impact piece and the outer contour of the stirring bag fit each other, so that the energy of gas or liquid impacting the inner wall of the spoiler impact piece is more balanced, and the energy of impacting the sediment is more stable.

[0009] In some embodiments, the bottom of the kettle body is provided with a driven component that assists in driving the spoiler impact piece to rotate around the stirring capsule; the driven component includes a driven gear, which is sleeved on the connecting rod and fixed to the spoiler impact piece; and also includes an annular rack, which is coaxially arranged at the bottom of the kettle body and meshes with the driven gear. Therefore, as the bottom rotating shaft rotates, the driven gear and the annular rack mesh with each other, and drive the spoiler impact piece to actively rotate around the stirring capsule, which, on the one hand, has the effect of stirring and dissolving the surrounding materials, and on the other hand, improves the efficiency of impacting and breaking up the sediments in each area.

[0010] In some embodiments, the stirring capsule is a spherical or ellipsoidal capsule, so that, on the one hand, the through holes opened on the side of the stirring capsule are more dispersed and have a wider function, and on the other hand, during the rotation of the bottom rotating shaft, the resistance with the solution is reduced, so that the stirring capsule rotates more stably and flexibly.

[0011] In some embodiments, the gaps between the support capsule and the stirring capsule are equal in each area. Therefore, when gas or liquid is introduced into the bottom rotating shaft, the liquid or gas fills the space inside the stirring capsule more quickly, and the flow rate of the liquid or gas out of the through hole of the stirring capsule is more uniform, which also makes the stirring capsule rotate more stably.

[0012] In some embodiments, the inner wall of the spoiler impact piece is provided with a plurality of spoiler convex strips. Thus, when the gas or liquid discharged from the through hole of the stirring capsule impacts the spoiler impact piece, the provision of the spoiler convex strips will redirect the flow direction of the gas or liquid, thereby increasing the impact on the precipitate to be more sufficient and improving the efficiency of dissolving and mixing the precipitate.

[0013] A production process of a desulfurizer, the specific process is as follows:

[0014] Discharging: Add the solid and liquid materials of the desulfurizer into the reactor body according to the formula, of which water is first added to 4 / 5 of the total content, and the remaining 1 / 5 is reserved;

[0015] Pre-dissolution, start the main motor to drive the top rotating shaft to rotate, and keep the top rotating shaft at a speed of 60r / min to stir the solution in the kettle, and stir for 5-10 minutes;

[0016] After initial dissolution, adjust the power of the main motor to increase the speed of the top rotating shaft to 90r / min and stir for 8-10 minutes;

[0017] Let the solution stand, turn off the main motor, and let it stand for 5-8 minutes;

[0018] Sedimentation stirring, start the auxiliary motor, make the bottom rotating shaft rotate at a speed of 60r / min, and make the stirring bag stir the sediment. During this period, the remaining 1 / 5 of the spare water in the discharge process is introduced into the bottom rotating shaft through the water pump, and the water is sprayed out through the through hole of the stirring bag at a high speed, and stirred for 3-5 minutes;

[0019] After all the reserve water is introduced, the high-pressure gas is introduced into the stirring bag through the bottom rotating shaft, and the high-pressure gas is ejected through the through hole of the stirring bag to assist in stirring the solution in the kettle body for 3-5 minutes;

[0020] After mixing the whole, start the main motor and make the top rotating shaft rotate at a speed of 90r / min for 5 minutes;

[0021] Shut down the machine and drain the liquid, turn off the main motor and auxiliary motor, open the drain valve, and transfer the solution in the kettle to sediment.

[0022] By having the above-mentioned technical features, in order to dissolve, the solution is first driven to flow through the top rotating shaft rotating at a low speed to reduce the resistance caused by the solid or liquid to the rotation of the top rotating shaft; after the solution flows in the kettle, the rotation speed of the main motor is increased to improve the efficiency of solid-liquid mixing, and then the undissolved solid material is precipitated to the bottom of the kettle by standing, so that the stirring capsule can fully act on the precipitate, and the stirring capsule is driven by the auxiliary motor to act on the bottom precipitate at multiple levels, thereby improving the efficiency of solid-liquid mixing, and finally, by controlling the differential rotation speeds of the top rotating shaft and the bottom rotating shaft, turbulence is formed in the kettle, which also improves the overall solid-liquid mixing efficiency and ultimately achieves mixing uniformity.

[0023] It should be understood that the contents described in the summary of the invention are not intended to limit the key or important features of the embodiments of the present disclosure, nor are they intended to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Hereinafter, preferred embodiments (or implementation modes) of the present invention will be described in detail with reference to the accompanying drawings.

[0032] Reference below Figure 1-Figure 5 To describe a mixing device for producing a granular desulfurizer and a production process thereof of the present invention.

[0033] Figure 1 The overall structure schematic diagram of a mixing device for producing a granular desulfurizing agent provided by an embodiment of the present invention is shown. Figure 1 As shown, a mixing device for producing a granular desulfurizer provided in this embodiment includes a kettle body 1, on which a feed inlet 11 and an observation port 12 are provided, a top stirring device 2 is provided at the top of the kettle body 1, a bottom stirring device 3 is provided at the bottom of the kettle body 1, and a drain port 13 which is interconnected with the internal space of the kettle body 1 is also provided at the bottom of the kettle body 1 and is opened and closed by a drain valve 14.

[0034] Figure 2 A cross-sectional view of a mixing device for producing a granular desulfurizing agent provided by an embodiment of the present invention is shown. Figure 2As shown, the top stirring device 2 includes a main motor 21 coaxially arranged on the top of the kettle body 1, the output end of the main motor 21 faces the inner direction of the kettle body 1, and the output shaft of the main motor 21 is coaxially arranged with the kettle body 1, and the main body of the main motor 21 is fixed to the edge of the upper port of the kettle body 1; the output shaft of the main motor 21 is coaxially fixed with a top rotating shaft 22, and the peripheral side branches of the top rotating shaft 22 are provided with a plurality of top stirring blades 23, and by starting the main motor 21, the top stirring blades 23 are driven to rotate around the top rotating shaft 22 in the kettle body 1, thereby stirring and mixing the solution in the kettle body 1.

[0035] Figure 3 The schematic diagram of the structure of the bottom stirring device 3 in the mixing device for producing the granular desulfurizing agent provided by the embodiment of the present invention is shown. Figure 3 As shown, the bottom stirring device 3 includes a bottom rotating shaft 31 which is penetrated through the bottom of the kettle body 1. The bottom rotating shaft 31 is partially located at the bottom of the kettle body 1 and partially located inside the kettle body 1. The bottom rotating shaft 31 is sealed and rotatably connected with the kettle body 1 at the connection point, and the bottom rotating shaft 31 is coaxially arranged with the kettle body 1. A driving assembly for driving the bottom rotating shaft 31 to rotate is arranged at the bottom of the bottom rotating shaft 31. The driving assembly is an auxiliary motor 32 fixed at the bottom of the kettle body 1 and a transmission assembly 33 connected between the auxiliary motor 32 and the bottom rotating shaft 31. The transmission assembly 33 can be a gear drive or a belt drive, which will not be repeated here. A plurality of connecting rods 34 are transversely arranged at the top of the bottom rotating shaft 31, and a sac-shaped stirring assembly 35 is arranged at the end of each connecting rod 34. The bottom surface of the bottom rotating shaft 31 is open, and a channel is also arranged therein which is interconnected with the inside of the sac-shaped stirring assembly 35, so as to facilitate the high-pressure gas or liquid to pass through the bottom of the bottom rotating shaft 31 into the sac-shaped stirring assembly 35.

[0036] Figure 4 The cross-sectional view of a capsule-type stirring assembly in a mixing device for producing a granular desulfurizing agent provided by an embodiment of the present invention is shown. Figure 4As shown, the capsule-shaped stirring assembly 35 includes a supporting capsule 351 fixed at the end of the connecting rod 34, and a stirring capsule 352 that wraps the supporting capsule 351 and is rotatably connected to the connecting rod 34; wherein the supporting capsule 351 and the stirring capsule 352 have the same shape, and can be both spherical capsules or both ellipsoidal capsules. The figure takes the stirring capsule 352 as an ellipsoid as an example. The supporting capsule 351 and the connecting rod 34 are coaxial with each other, and the end of the connecting rod 34 is located in the package of the stirring capsule 352, and a plurality of gas-liquid ports 341 that are interconnected with the internal channel of the bottom rotating shaft 31 are opened around the end of the connecting rod 34, so that the gas or liquid introduced into the bottom rotating shaft 31 can quickly fill the gap between the supporting capsule 351 and the stirring capsule 352, and a plurality of through holes 3521 are evenly opened around the stirring capsule 352, so that the gas or liquid introduced into the bottom rotating shaft 31 can be quickly discharged into the kettle body 1 through the through holes 3521 of the stirring capsule 352 in multiple directions.

[0037] In order to make the gas or liquid filled into the bottom rotating shaft 31 be discharged through the through hole 3521 of the stirring capsule 352 more stably and evenly, the gaps in each area between the support capsule 351 and the stirring capsule 352 are set more balanced, which not only makes the gas or liquid fill the internal space of the stirring capsule 352 more efficiently, but also makes the flow rate of the gas or liquid through the through hole 3521 of the stirring capsule 352 more uniform and stable.

[0038] In order to make the gas or liquid discharged from the through hole 3521 of the stirring capsule 352 flow in a wider range, the inner wall of the stirring capsule 352 is also provided with a plurality of arc-shaped guide pieces 36, one side of the guide piece 36 is fixed to the inner wall of the stirring capsule 352, and the other side has a gap with the outer wall of the support capsule 351. When the bottom rotating shaft 31 is filled with gas or liquid, the gas or liquid impacts the plurality of guide pieces 36 under the guidance of the inner wall of the stirring capsule 352, thereby changing the direction of the force and driving the stirring capsule 352 to rotate around the connecting rod 34, thereby improving the stirring efficiency and contact range between the stirring capsule 352 and the surrounding solution.

[0039] In order to improve the dissolution efficiency of the bottom sediment, each connecting rod 34 is also rotatably connected to a spoiler impact piece 37, the overall shape of which matches the outer contour of the stirring capsule 352, and is located on the peripheral side of the stirring capsule 352 and is spaced apart from the stirring capsule 352. Each connecting rod 34 is also coaxially rotatably connected to a driven gear 41, which is fixed to the spoiler impact piece 37, and a ring rack 42 is coaxially arranged on the bottom wall of the kettle body 1. As the connecting rod 34 rotates, the driven gear 41 is driven to mesh with the ring rack 42, thereby driving the spoiler impact piece 37 to rotate around the stirring capsule 352. In actual operation, as the spoiler impact piece 37 rotates, the sediment will flow into the gap between the spoiler impact piece 37 and the stirring capsule 352. As the gas or liquid filled into the bottom rotating shaft 31 is ejected at high speed through the through hole 3521 of the stirring capsule 352, the gas or liquid impacts the inner wall of the spoiler impact piece 37, and its dispersion effect will accelerate the solution and mixing of the sediment, thereby improving the dissolution and mixing efficiency of the solid sediment. In addition, a plurality of strip-shaped spoiler convex strips 38 are fixedly connected to the inner arc surface of the spoiler impact piece 37, which further changes the flow direction of the gas or liquid, improves the mixing effect of the solution flow, and also improves the rigidity of the spoiler impact piece 37, ensuring the stability of the spoiler impact piece 37 for long-term operation.

[0040] Figure 5 The following is a production process flow chart of a mixing device for producing a granular desulfurizing agent provided by an embodiment of the present invention. Figure 5 As shown, a production process of a mixing device for producing a granular desulfurizing agent comprises the following steps:

[0041] Step 1: discharge the materials. Add the solid material and liquid material of the desulfurizer into the kettle body 1 through the inlet 11 of the kettle body 1 according to the ratio. When putting in the materials, the liquid material can be put in first, and then the solid material. The dust generated when the solid material is put in can be reduced by the rising of the liquid, so as to reduce unnecessary impact on the staff. Among them, the solvent water needs to be put into 4 / 5 of the total capacity according to the ratio, and the remaining 1 / 5 of the capacity is stored separately for standby.

[0042] Step 2: Pre-dissolution, start the main motor 21, drive the top rotating shaft 22 to rotate, and make the top stirring blade 23 on the side of the top rotating shaft 22 rotate in the kettle body 1, and stir the solution in the kettle body 1. Since most of the solid materials in the kettle body 1 are still on the surface of the liquid, the output speed of the main motor 21 is set at 60r / min, and stirring is continued for 5-10 minutes. On the one hand, the stirring resistance between the top stirring blade 23 and the liquid material and the solid material during stirring is reduced; on the other hand, the scattering of solid materials is reduced, so that the solid materials are slowly merged with the liquid materials; on the third hand, the flow of the solution in the kettle body 1 is driven, which is also convenient for the subsequent processes.

[0043] Step 3: Preliminary dissolution, adjust the speed of the main motor 21 to 90r / min to improve the stirring efficiency of the top stirring blade 23 on the solid-liquid mixing in the kettle body 1, and continue stirring for 8-10 minutes. During this period, the dissolution degree of the solid material in the kettle body 1 can be observed through the observation port 12 of the kettle body 1. The purpose of this step is to ensure that there is no solid material remaining on the liquid surface.

[0044] Step 4: Let the solution stand, turn off the main motor 21, and let the solution stand for 5-8 minutes. During this period, the inside of the kettle body 1 can also be observed through the observation port 12. If the solution does not flow obviously, let it stand for another 3 minutes before proceeding to the subsequent process.

[0045] Step 5: Precipitation and stirring, start the auxiliary motor 32, and set the speed of the auxiliary motor 32 to 60r / min, so that the bottom rotating shaft 31 drives the stirring capsule 352 to rotate and stir the solution in the kettle body 1, and continue stirring for 3-5 minutes. After the auxiliary motor 32 is started for 10 seconds, the spare 1 / 5 of water is pumped into the bottom rotating shaft 31 through the water pump, and the liquid passes through the through hole 3521 of the stirring capsule 352 at high speed. The impact of the high-speed flowing liquid on the guide plate 36 drives the stirring capsule 352 to rotate, so that when the stirring capsule 352 rotates around the bottom rotating shaft 31, it also rotates at high speed, further increasing the impact of the liquid on the surrounding sediment, and increasing the efficiency of sediment dissolution and stirring. In addition, during the rotation of the connecting rod 34, the meshing of the driven gear 41 and the annular rack 42 drives the spoiler impact plate 37 to rotate around the stirring capsule 352, so that the sediment flowing into the gap between the spoiler impact plate 37 and the stirring capsule 352 is impacted by the high-speed water flow, which accelerates the dispersion efficiency and improves the dissolution efficiency.

[0046] Step 6: Introduce high-pressure gas and all the inlets with spare water, replace the bottom of the bottom rotating shaft 31 with a high-pressure gas interface and introduce high-pressure gas, and continue stirring for 3-5 minutes. The high-pressure gas can not only drive the stirring bag 352 to rotate, but also after the gas is ejected, the bubbles generated will float above the liquid surface of the kettle body 1, thereby also driving the sediment to flow and accelerating the dissolution and stirring efficiency.

[0047] Step 7: Mix the whole, start the main motor 21, and maintain the rotation speed of 90 / min, and continue stirring for 5 minutes to create a speed difference between the top rotating shaft 22 and the bottom rotating shaft 31, so that the liquid flows to form a mixed flow, thereby accelerating the mixing efficiency of the solid material and the liquid material.

[0048] Step 8: Shut down the machine to drain the liquid, turn off the main motor 21 and the auxiliary motor 32, open the drain valve 14, and transfer the mixed solution to the sedimentation tank for subsequent sedimentation operations.
