Description

Technical Field

[0001] The present invention belongs to the technical field of blast furnace gas treatment, and particularly relates to a liquid spraying device for a blast furnace gas desulfurization tower. Background Art

[0002] The existing blast furnace gas desulfurization treatment mainly relies on a desulfurization tower. The gas is introduced into the interior of the desulfurization tower from bottom to top, and then the reaction liquid is sprayed by the spraying equipment inside the tower body to react with the sulfur element in the gas. For example, the Chinese utility model patent with the authorization announcement number CN215233284U discloses a blast furnace gas desulfurization tower and an internal liquid spraying device for the blast furnace gas desulfurization tower. In this solution, one or more layers of liquid spraying devices are arranged in the blast furnace gas desulfurization tower along the height direction for desulfurization treatment.

[0003] However, the liquid spraying devices used in the existing blast furnace gas desulfurization towers are mainly composed of pipelines and spray heads, spraying the reaction liquid from top to bottom, and then the gas flows from bottom to top to achieve contact reaction. However, when the gas passes through the spraying area, the flow rate is mostly relatively fast and the gas flow rate per unit time is also relatively large. When the reaction liquid is sprayed, it directly passes through the flowing gas and contacts it. Such operation is likely to cause some gas to flow through directly without fully contacting the reaction liquid, thus unable to ensure the desulfurization effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a liquid spraying device for a blast furnace gas desulfurization tower to solve the problem of poor desulfurization reaction treatment effect in the existing blast furnace gas desulfurization liquid spraying device.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A liquid spraying device for a blast furnace gas desulfurization tower, comprising:

[0007] A desulfurization tower body, inside which a sealing baffle is provided, and the internal space of the desulfurization tower body is divided into an upper cavity and a lower cavity by the sealing baffle. A cylindrical separation transition cylinder is provided on the sealing baffle, and the gap between the separation transition cylinder and the inner wall of the desulfurization tower body is sealed by the sealing baffle. Through openings are provided on both the upper and lower sides of the separation transition cylinder, and the two through openings connect the upper cavity and the lower cavity. On this basis, a rotating separation member for evenly dividing the internal space of the separation transition cylinder into a plurality of reaction chambers is rotatably arranged inside the separation transition cylinder, and a vibration mechanism for vibrating the gas is further provided on the rotating separation member. The rotating end of the rotating separation member is cooperatively provided with a power assembly, and the rotating separation member rotates by the power of the power assembly, so that the blast furnace gas entering the separation transition cylinder from the lower through opening of the separation transition cylinder is sequentially separated by a plurality of reaction chambers, and after running half a circle in the separation transition cylinder, it is sequentially discharged from the upper through opening of the separation transition cylinder;

[0008] The reaction liquid storage mechanism includes a liquid storage cylinder and a first one-way valve. The liquid storage cylinder is arranged on the outer side of the desulfurization tower body through a support frame and is used to store the reaction liquid. The first one-way valve is installed at the bottom of the liquid storage cylinder and is used to output the reaction liquid inside the liquid storage cylinder unidirectionally.

[0009] The liquid feeding mechanism is arranged below the liquid storage cylinder. The liquid feeding mechanism includes a piston cylinder. The piston cylinder is communicated with the first one-way valve and is used to receive the reaction liquid inside the liquid storage cylinder. One end of the piston cylinder is communicated to the inside of the desulfurization tower body through a liquid outlet conduit. The end of the liquid outlet conduit located inside the desulfurization tower body is connected with a plurality of atomizing nozzles through a plurality of hoses, and the plurality of atomizing nozzles are evenly spaced on the circumferential side wall of the partition transition cylinder. In addition, a second one-way valve is also arranged on the liquid outlet conduit and is used to unidirectionally output the reaction liquid in the piston cylinder to the atomizing nozzles and then spray it into the reaction cavity. On this basis, a piston block is slidably fitted inside the piston cylinder, and the piston block is connected with the power assembly through a transmission assembly.

[0010] Preferably, an air inlet pipe located in the lower cavity is further arranged on one side of the bottom of the desulfurization tower body and is used to convey blast furnace gas into the desulfurization tower body. A booster air pump is also arranged on the air inlet pipe. In addition, a funnel cylinder is arranged at the bottom of the desulfurization tower body and is used to guide the reaction liquid that has reacted with the blast furnace gas to flow out. The funnel cylinder is provided with a control valve. On this basis, an exhaust pipe located in the upper cavity is further arranged at the top of the desulfurization tower body and is used to discharge the reacted blast furnace gas.

[0011] More preferably, the rotary partition member includes an inner rotating cylinder and partition pushing plates. The inner rotating cylinder is rotatably arranged inside the partition transition cylinder. A plurality of partition pushing plates are provided, and the plurality of partition pushing plates are evenly spaced along the circumferential outer wall of the inner rotating cylinder. The side of each partition pushing plate away from the inner rotating cylinder fits with the inner wall of the partition transition cylinder. The space between the inner rotating cylinder and the partition transition cylinder is divided into a plurality of reaction cavities by the plurality of partition pushing plates.

[0012] Preferably, in the rotary partition member, the vibration mechanism includes a star-shaped wheel body and an elastic vibration assembly. Among them, a plurality of star-shaped protrusions are evenly distributed on the circumferential surface of the star-shaped wheel body, and the star-shaped wheel body is placed inside the inner rotating cylinder. One side of the inner rotating cylinder is open. One end of the star-shaped wheel body passes through the open end of the inner rotating cylinder and is fixedly connected with the partition transition cylinder. In addition, a plurality of groups of elastic vibration assemblies are provided, and each group of elastic vibration assemblies is correspondingly distributed between two adjacent partition pushing plates.

[0013] Further, in the rotary separator, each set of the elastic vibration components includes a plurality of elastic sheets equidistantly distributed along the axial direction of the built-in rotary cylinder. One end of each elastic sheet away from the inner wall of the separation transition cylinder penetrates into the interior of the built-in rotary cylinder and extends between two adjacent star-shaped protrusions of the star wheel body. In addition, each set of elastic vibration components is also provided with elastic blocks at the corresponding positions where each elastic sheet penetrates the built-in rotary cylinder.

[0014] Furthermore, the power assembly includes a motor disposed on the mounting plate. The motor is located on one side of the desulfurization tower body, and the output end of the motor is connected to a first rotating shaft. After the first rotating shaft penetrates the side wall of the desulfurization tower body, it is connected to the built-in rotary cylinder, so that the built-in rotary cylinder rotates uniformly in the separation transition cylinder by means of the power provided by the motor.

[0015] Preferably, in the reaction liquid storage mechanism, a supply pump for replenishing the reaction liquid into the liquid storage cylinder is installed at the top of the liquid storage cylinder.

[0016] Preferably, in the liquid delivery mechanism, the transmission assembly includes: a power transmission mechanism for initially transmitting the power output by the power assembly, and a reciprocating push-pull mechanism for reciprocatingly pushing and pulling the piston block. The power transmission mechanism includes a main gear fixedly disposed on the first rotating shaft, a sub-gear rotatably disposed on the outer wall of the desulfurization tower body through a second rotating shaft, and a first steering bevel gear fixedly disposed at the end of the second rotating shaft. Among them, the main gear meshes with the sub-gear. In addition, the power transmission mechanism further includes a second steering bevel gear meshing with the first steering bevel gear, and the second steering bevel gear is used to steer and output the power transmitted by the power transmission mechanism to the reciprocating push-pull mechanism.

[0017] Further, the reciprocating push-pull mechanism includes an axle bracket disposed on one side of the piston cylinder. One end of the axle bracket is fixed to the support frame, and the other end of the axle bracket is rotatably connected to the middle of a third rotating shaft. One end of the third rotating shaft is fixedly connected to a second linkage rod, and the other end of the third rotating shaft is fixedly connected to the second steering bevel gear. In addition, the end of the second linkage rod is rotatably connected to one end of a first linkage rod through a rotating pin, and the other end of the first linkage rod is rotatably connected to one end of a push rod through a rotating pin. The end of the push rod away from the first linkage rod is fixedly connected to the piston block. When the power assembly drives the transmission assembly to move, each component in the power transmission mechanism and the reciprocating push-pull mechanism does not interfere with each other.

[0018] The beneficial effects of the present invention are as follows:

[0019] The present invention introduces the blast furnace gas that needs to undergo desulfurization reaction into the partition transition cylinder. The internal space of the partition transition cylinder is divided into multiple reaction chambers by a plurality of partition push plates, facilitating the quantitative distribution of the incoming blast furnace gas in different reaction chambers, and enabling a relatively small amount of gas in each reaction chamber to fully react with the reaction liquid. In addition, the partition push plates also rotate with the built-in rotating cylinder. On the premise of ensuring that the gas and the reaction liquid in each reaction chamber can react, it can also push the gas to continue to move forward, facilitating the flow of the gas to the next process for further treatment.

[0020] On this basis, the built-in rotating cylinder provided by the present invention can rotate at a relatively low speed, ensuring that the gas and the reaction liquid in each reaction chamber have sufficient time to contact and react. At the same time, during the rotation of the built-in rotating cylinder, the elastic vibration components distributed in each reaction chamber continuously collide and squeeze with the star-shaped protrusions of the fixedly arranged star-shaped wheel body as the built-in rotating cylinder rotates, so that the elastic vibration components continuously generate vibrations, and then vibrate the gas in the reaction chamber to facilitate full contact and reaction with the reaction liquid.

[0021] In addition, during the process of driving the built-in rotating cylinder to rotate by the motor, the motor also drives the push-pull rod to reciprocate through the transmission component, and then drives the piston block in the piston cylinder to reciprocate by using the push-pull rod. Under the one-way liquid delivery action of the first one-way valve and the second one-way valve, the piston cylinder continuously sucks the reaction liquid in the liquid storage cylinder, and then transports it to the atomizing nozzle for atomizing ejection during the reaction, further improving the reaction effect between the reaction liquid and the gas. On this basis, the liquid delivery mechanism does not need to be separately provided with a driving source for driving, and starts and stops synchronously with the built-in rotating cylinder, saving costs.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The technical solutions of the present application will be introduced in detail below with reference to the drawings.

[0035] In the present technical solution, as Figure 1 shown, the liquid spraying device for a blast furnace gas desulfurization tower includes a desulfurization tower body 1, a reaction liquid storage mechanism 2, and a liquid delivery mechanism 3. The liquid delivery mechanism 3 sends the reaction liquid in the reaction liquid storage mechanism 2 into the interior of the desulfurization tower body 1 and makes the reaction liquid react with the blast furnace gas inside the desulfurization tower body 1 to achieve desulfurization.

[0036] Among them, as Figure 1-4 shown, the desulfurization tower body 1 is a carrier for the desulfurization reaction of blast furnace gas. A sealing baffle 101 is provided inside the desulfurization tower body 1, and the internal space of the desulfurization tower body 1 is divided into an upper cavity and a lower cavity by the sealing baffle 101. In addition, a cylindrical partition transition cylinder 4 is provided on the sealing baffle 101, and the sealing baffle 101 seals the gap between the partition transition cylinder 4 and the inner wall of the desulfurization tower body 1. Through holes 401 are provided on both the upper and lower sides of the partition transition cylinder 4. The two through holes 401 are respectively located in the upper cavity and the lower cavity, and the two through holes 401 connect the upper cavity and the lower cavity; on this basis, an intake pipe 102 located in the lower cavity is further provided on one side of the bottom of the desulfurization tower body 1 for delivering blast furnace gas into the interior of the desulfurization tower body 1, and an exhaust pipe 103 located in the upper cavity is further provided at the top of the desulfurization tower body 1 for discharging the reacted blast furnace gas.

[0037] Based on the above embodiments, after the blast furnace gas enters the desulfurization tower body 1 from the inlet pipe 102, under the interaction of the sealing baffle 101 and the partition transition cylinder 4, the blast furnace gas can only enter the partition transition cylinder 4 from the lower side opening 401 of the partition transition cylinder 4, and then flow out from the upper side opening 401 until it flows out of the desulfurization tower body 1 from the exhaust pipe 103. In order to ensure that the blast furnace gas has a certain air pressure and flow rate, a booster pump is also installed on the inlet pipe 102 to enhance the air pressure and flow rate of the blast furnace gas through the booster pump, so that the blast furnace gas to be desulfurized reacts and flows upward from the bottom after entering the interior of the desulfurization tower body 1; in addition, a funnel cylinder 104 is provided at the bottom of the desulfurization tower body 1 for guiding the reaction liquid that has reacted with the blast furnace gas to flow out, and a control valve is arranged in cooperation with the funnel cylinder 104 to control the on-off of the funnel cylinder 104.

[0038] In the above illustrated structure, in the present application, the reaction liquid and the blast furnace gas will react in the partition transition cylinder 4. Specifically, the present invention will specifically describe the partition transition cylinder 4 and its internal specific structure.

[0039] As Figure 4-7 shown, a rotating partition member 404 for evenly dividing the internal space of the partition transition cylinder 4 into a plurality of reaction chambers is rotatably arranged inside the partition transition cylinder 4, and a vibration mechanism 5 for vibrating the gas is provided on the rotating partition member 404. A power assembly 6 is arranged in cooperation with the rotating end of the rotating partition member 404. The rotating partition member 404 rotates by means of the power of the power assembly 6, so that the blast furnace gas entering the partition transition cylinder 4 from the lower side opening 401 of the partition transition cylinder 4 is sequentially separated by a plurality of reaction chambers and discharged from the upper side opening 401 of the partition transition cylinder 4 after running half a circle in the partition transition cylinder 4.

[0040] Specifically, as Figure 5-7 shown, the rotating partition member 404 includes an inner rotating cylinder 402 and a partition pushing plate 403. The inner rotating cylinder 402 is rotatably arranged inside the partition transition cylinder 4. A plurality of partition pushing plates 403 are provided, and the plurality of partition pushing plates 403 are evenly spaced along the circumferential outer wall of the inner rotating cylinder 402. The side of each partition pushing plate 403 away from the inner rotating cylinder 402 fits with the inner wall of the partition transition cylinder 4. The space between the inner rotating cylinder 402 and the partition transition cylinder 4 is divided into several reaction chambers by the plurality of partition pushing plates 403. When the blast furnace gas enters the partition transition cylinder 4 from the opening 401 at the bottom of the partition transition cylinder 4, the blast furnace gas will enter each reaction chamber quantitatively under the condition that the rotating partition member 404 rotates at a constant speed.

[0041] The rotational movement of the rotating partition member 404 is provided by the power assembly 6, as Figure 1-4As shown, the power assembly 6 includes a motor 602 disposed on the mounting plate 601. The motor 602 is located on one side of the desulfurization tower body 1, and the output end of the motor 602 is connected to a first rotating shaft 603. After the first rotating shaft 603 penetrates through the side wall of the desulfurization tower body 1, it is connected to the built-in rotating cylinder 402, so that the built-in rotating cylinder 402 rotates uniformly in the separation transition cylinder 4 by means of the power provided by the motor 602.

[0042] In this technical solution, the blast furnace gas will contact and react with the reaction liquid in the reaction chamber in a moving state. In order to improve the reaction effect, the present application also provides a vibration mechanism 5 on the rotating separator 404, such as Figure 5-7 As shown, the vibration mechanism 5 includes a star wheel body 501 and an elastic vibration assembly 502. Among them, a number of star-shaped protrusions are evenly distributed circumferentially on the surface of the star wheel body 501, and the star wheel body 501 is placed inside the built-in rotating cylinder 402. One side of the built-in rotating cylinder 402 is open, and one end of the star wheel body 501 passes through the open end of the built-in rotating cylinder 402 and is fixedly connected to the separation transition cylinder 4; in addition, several groups of elastic vibration assemblies 502 are provided, and each group of elastic vibration assemblies 502 is correspondingly distributed between two adjacent separation push plates 403. Each group of elastic vibration assemblies 502 includes a number of elastic sheets 503 evenly distributed along the axial direction of the built-in rotating cylinder 402. One end of each elastic sheet 503 away from the inner wall of the separation transition cylinder 4 penetrates into the inside of the built-in rotating cylinder 402 and extends between two adjacent star-shaped protrusions of the star wheel body 501. When the built-in rotating cylinder 402 drives the elastic sheet 503 to rotate, the extending end of the elastic sheet 503 extending between the star-shaped protrusions will be successively squeezed against the star-shaped protrusions on the star wheel body 501 during the rotation process and then rebound to generate vibration, thereby generating a vibration effect on the blast furnace gas in the reaction chamber. In addition, each group of elastic vibration assemblies 502 is also provided with an elastic block 504 at the corresponding position where each elastic sheet 503 penetrates through the built-in rotating cylinder 402.

[0043] It should be noted that the star-shaped wheel body 501 is a star-shaped structure with a plurality of star-shaped protrusions circumferentially distributed on its surface, and the distribution density of the star-shaped protrusions can be selected according to actual needs. Since the star-shaped wheel body 501 is fixed relative to the separation transition cylinder 4, while the elastic vibration assembly rotates with the built-in cylinder 402, during the rotation of the built-in cylinder 402, one end of the elastic sheet 503 in each elastic vibration assembly will successively squeeze the star-shaped protrusion position of the star-shaped wheel body 501, and then the elastic sheet 503 deforms and rebounds to vibrate, so that the entire elastic vibration assembly vibrates, further promoting the vibration of the blast furnace gas in the corresponding reaction chamber, enhancing the movement degree of the blast furnace gas, facilitating full contact reaction with the reaction liquid, and improving the desulfurization effect. In addition, due to the vibration of the vibration mechanism 5, even when the built-in cylinder 402 rotates at a relatively slow speed, the movement intensity of the blast furnace gas can still be enhanced, and the situation where the built-in cylinder 402 rotates at a relatively slow speed can ensure that the blast furnace gas exists in the reaction chamber inside the separation transition cylinder 4 for a long time, further ensuring the desulfurization reaction.

[0044] So far, the structural basis for the operation of the blast furnace gas and the specific position basis for carrying out the desulfurization reaction are obtained.

[0045] In addition, the reaction liquid required for the desulfurization reaction of the blast furnace gas is provided by the cooperation of the reaction liquid storage mechanism 2 and the liquid delivery mechanism 3. As Figure 2 shown, the reaction liquid storage mechanism 2 includes a liquid storage cylinder 201 and a first one-way valve 202. The liquid storage cylinder 201 is arranged on the outer side of one side of the desulfurization tower body 1 through a support frame 203 for storing the reaction liquid. The first one-way valve 202 is installed at the bottom of the liquid storage cylinder 201 for unidirectionally outputting the reaction liquid inside the liquid storage cylinder 201. In addition, a supply pump for replenishing the reaction liquid into the liquid storage cylinder 201 is installed at the top of the liquid storage cylinder 201.

[0046] As Figure 1-3 shown, the liquid delivery mechanism 3 is arranged below the liquid storage cylinder 201. The liquid delivery mechanism 3 includes a piston cylinder 301. The piston cylinder 301 is communicated with the first one-way valve 202 for receiving the reaction liquid inside the liquid storage cylinder 201. One end of the piston cylinder 301 is communicated to the inside of the desulfurization tower body 1 through a liquid outlet conduit 302. The end of the liquid outlet conduit 302 located inside the desulfurization tower body 1 is connected with a plurality of atomizing nozzles 304 through a plurality of hoses 303, and the plurality of atomizing nozzles 304 are evenly spaced and distributed on the circumferential side wall of the separation transition cylinder 4. In addition, a second one-way valve is also arranged on the liquid outlet conduit 302 for unidirectionally outputting the reaction liquid in the piston cylinder 301 to the atomizing nozzles 304 and then spraying it into the reaction chamber.

[0047] On this basis, a piston block 305 is slidably fitted inside the piston cylinder 301. The piston block 305 is connected to the power assembly 6 through a transmission assembly. The transmission assembly includes: a power transmission mechanism 7 for initially transmitting the power output by the power assembly 6, and a reciprocating push-pull mechanism 8 for reciprocatingly pushing and pulling the piston block 305.

[0048] As Figure 1 , Figure 8 shown, the power transmission mechanism 7 includes a main gear 701 fixedly provided on the first rotating shaft 603, a sub-gear 703 rotatably provided on the outer wall of the desulfurization tower body 1 through a second rotating shaft 702, and a first steering bevel gear 704 fixedly provided at the end of the second rotating shaft 702. Among them, the main gear 701 meshes with the sub-gear 703. In addition, the power transmission mechanism 7 further includes a second steering bevel gear 705 meshing with the first steering bevel gear 704. In this embodiment, the second steering bevel gear 705 is used to steer and output the power transmitted by the power transmission mechanism 7 to the reciprocating push-pull mechanism 8.

[0049] The reciprocating push-pull mechanism 8 includes a shaft bracket 801 provided on one side of the piston cylinder 301. One end of the shaft bracket 801 is fixed to the support frame 203, and the other end of the shaft bracket 801 is rotatably connected to the middle of the third rotating shaft 802. One end of the third rotating shaft 802 is fixedly connected to a second linkage rod 803, and the other end of the third rotating shaft 802 is fixedly connected to the second steering bevel gear 705. In addition, the end of the second linkage rod 803 is rotatably connected to one end of the first linkage rod 804 through a pin, and the other end of the first linkage rod 804 is rotatably connected to one end of the push-pull rod 805 through a pin. The end of the push-pull rod 805 away from the first linkage rod 804 is fixedly connected to the piston block 305.

[0050] It should be noted that when the power assembly 6 drives the transmission assembly to move, each component in the power transmission mechanism 7 and the reciprocating push-pull mechanism 8 does not interfere with each other.

[0051] Based on the above embodiments, when the motor 602 drives the rotary separator 404 to rotate, the motor 602 also drives the main gear 701 to rotate at the same time. The main gear 701 drives the secondary gear 703 to rotate. At this time, the first steering bevel gear 704 rotates coaxially and synchronously with the secondary gear 703, and the first steering bevel gear 704 drives the second steering bevel gear 705 to rotate at the same time. At this time, the second linkage rod 803 makes a circular motion around the third rotating shaft 802 with the second steering bevel gear 705 as the axis; during the circular motion of the second linkage rod 803, the end away from the second steering bevel gear 705 reciprocally drives the push-pull rod 805 through the first linkage rod 804. During this process, the push-pull rod 805 drives the piston block 305 to reciprocate in the piston cylinder 301; specifically, when the piston block 305 is away from the liquid outlet conduit 302, it sucks a certain amount of reaction liquid from the liquid storage cylinder 201 through the first one-way valve 202. When the piston block 305 starts to approach the liquid outlet conduit 302, it squeezes the reaction liquid in the piston cylinder 301. During this process, the reaction liquid can only flow away through the second one-way valve from the liquid outlet conduit 302 and cannot enter the liquid storage cylinder 201 through the first one-way valve 202. In this way, the reaction liquid is transported to the atomizing nozzle 304 through the piston cylinder 301 and the liquid outlet conduit 302, and then sprayed into the reaction chamber through the atomizing nozzle 304.

[0052] It should also be noted that the reaction liquid described in this application can be an alkaline solution, such as sodium hydroxide solution. Based on the chemical properties of the reaction liquid, all components directly in contact with the reaction liquid disclosed in the present invention are made of materials that do not react with it. For example, the materials of the elastic sheet 503 and the elastic block 504 in this application are both made of polytetrafluoroethylene; in order to further ensure the effect of the desulfurization reaction, the piston cylinder 301 can be set to a larger size to ensure that the amount of reaction liquid injected each time reaches a sufficient amount, so as to ensure that a sufficient amount of reaction liquid is sprayed into the separation transition cylinder 4. And because a plurality of atomizing nozzles 304 are evenly spaced on the side wall of the separation transition cylinder 4, when the rotary separator rotates at a slower speed, the blast furnace gas in each reaction chamber can be sprayed with liquid multiple times, thereby ensuring the reaction effect.

[0053] To facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0054] When using the liquid spraying device for blast furnace gas desulfurization tower provided by the present invention to desulfurize blast furnace gas, the blast furnace gas to be desulfurized is introduced into the desulfurization tower body 1 through the air inlet pipe 102 and flows from bottom to top. Then the blast furnace gas enters from the through hole 401 on the lower side of the separation transition cylinder 4 and enters different reaction chambers in portions during the rotation of the rotary separator. At this time, the blast furnace gas slowly moves upward in the reaction chamber towards the through hole 401 on the upper side of the separation transition cylinder 4.

[0055] During the rotation of the rotary separator, the power assembly 6 also drives the transmission assembly to move. At this time, the reciprocating push-pull mechanism 8 cooperates with the liquid supply mechanism 3 to send the reaction liquid in the liquid storage cylinder 201 into the separation and transition cylinder 4, and the atomizing nozzle 304 atomizes and sprays the reaction liquid into each reaction chamber, so that the blast furnace gas in each reaction chamber fully reacts with the reaction liquid. To improve the reaction effect, the present invention also sets a vibration mechanism 5 on the rotary separator. While the power assembly 6 provides rotational power for the rotary separator, the blast furnace gas in the reaction chamber is vibrated through the cooperation of the star wheel body 501 and the elastic vibration assembly, so that it fully contacts and reacts with the atomized reaction liquid, improving the reaction effect.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
