Description

Technical Field

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

[0002] The existing blast furnace gas desulfurization treatment is mainly carried out by a desulfurization tower, where the gas is passed from bottom to top into the desulfurization tower, and then the spraying equipment inside the tower sprays the reaction liquid 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 a liquid spraying device in a blast furnace gas desulfurization tower. The scheme performs desulfurization treatment by arranging more than one layer of liquid spraying devices in the blast furnace gas desulfurization tower along the height direction.

[0003] However, the liquid spraying device used in the existing blast furnace gas desulfurization tower is mainly composed of a combination of pipes and spray heads. The reaction liquid is sprayed from top to bottom, and then the coal gas flows from bottom to top to achieve a contact reaction. However, when the coal gas passes through the spraying area, the flow rate is generally fast and the flow rate of the coal gas per unit time is also relatively large. When the reaction liquid is sprayed, it directly passes through the flowing coal gas and contacts it. Such operation can easily cause part of the coal gas to flow through directly without fully contacting the reaction liquid, thereby failing to ensure the desulfurization effect.

[0010] Furthermore, the power assembly includes a motor arranged on a 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, the first rotating shaft passes through the side wall of the desulfurization tower body, and is connected to the built-in rotating drum, so that the built-in rotating drum rotates at a uniform speed in the separation transition cylinder with the help of the power provided by the motor.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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.

[0021] The technical solution of the present application will be described in detail below with reference to the accompanying drawings.

[0022] In this technical solution, if Figure 1 As shown, the liquid injection device for the 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 delivers the reaction liquid in the reaction liquid storage mechanism 2 into the desulfurization tower body 1, and makes the reaction liquid react with the blast furnace gas in the desulfurization tower body 1 to achieve desulfurization.

[0023] Among them, Figure 1-4 As 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 separation transition tube 4 is provided on the sealing baffle 101, and the sealing baffle 101 seals the gap between the separation transition tube 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 separation transition tube 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 air inlet pipe 102 located in the lower cavity is also provided on one side of the bottom of the desulfurization tower body 1, which is used to transport blast furnace gas to the inside of the desulfurization tower body 1, and an exhaust pipe 103 located in the upper cavity is also provided on the top of the desulfurization tower body 1, which is used to discharge the blast furnace gas after the reaction.

[0024] Based on the above embodiment, after the blast furnace gas enters the desulfurization tower body 1 from the air inlet pipe 102, the interaction between the sealing baffle 101 and the separation transition tube 4 allows the blast furnace gas to enter the separation transition tube 4 only from the lower side opening 401 of the separation transition tube 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 gas pressure and flow rate, a booster air pump is also installed on the air inlet pipe 102, and the gas pressure and flow rate of the blast furnace gas are enhanced by the booster air pump, so that the blast furnace gas to be desulfurized flows from bottom to top after entering the desulfurization tower body 1; in addition, a funnel tube 104 is also 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 the funnel tube 104 is provided with a control valve for controlling the opening and closing of the funnel tube 104.

[0025] In the above-illustrated structure, the reaction liquid and the blast furnace gas in the present application will react in the separation transition tube 4. Specifically, the present invention will specifically explain the separation transition tube 4 and the specific structure of the interior thereof.

[0026] like Figure 4-7 As shown, a rotating partition 404 is rotatably provided inside the separation transition tube 4 for evenly dividing the internal space of the separation transition tube 4 into a plurality of reaction chambers, and a vibration mechanism 5 for vibrating the gas is provided on the rotating partition 404. A power assembly 6 is provided at the rotating end of the rotating partition 4. The rotating partition 404 rotates with the power of the power assembly 6, so that the blast furnace gas entering the separation transition tube 4 from the lower side opening 401 of the separation transition tube 4 is sequentially separated by the plurality of reaction chambers, and is sequentially discharged from the upper side opening 401 of the separation transition tube 4 after running half a circle inside the separation transition tube 4.

[0027] Specifically, Figure 5-7 As shown, the rotating partition 404 includes a built-in rotating drum 402 and a partition push plate 403. The built-in rotating drum 402 is rotatably arranged inside the partition transition drum 4. A plurality of partition push plates 403 are provided, and the plurality of partition push plates 403 are evenly spaced and arranged along the circumferential outer wall of the built-in rotating drum 402. The side of each partition push plate 403 away from the built-in rotating drum 402 is in contact with the inner wall of the partition transition drum 4. The plurality of partition push plates 403 divide the space between the built-in rotating drum 402 and the partition transition drum 4 into a plurality of reaction chambers. When the blast furnace gas enters the partition transition drum 4 from the through port 401 at the bottom of the partition transition drum 4, the blast furnace gas will quantitatively enter each reaction chamber under the condition that the rotating partition 404 rotates at a uniform speed.

[0028] The rotational motion of the rotating partition 404 is provided by the power assembly 6, such as Figure 1-4As shown, the power assembly 6 includes a motor 602 arranged on a 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 passes through the side wall of the desulfurization tower body 1, it is connected to the built-in rotating drum 402, so that the built-in rotating drum 402 rotates at a uniform speed in the separation transition cylinder 4 with the help of the power provided by the motor 602.

[0029] 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 sets a vibration mechanism 5 on the rotating partition 404, such as Figure 5-7 As shown, the vibration mechanism 5 includes a star-shaped wheel body 501 and an elastic vibration component 502, wherein a plurality of star-shaped protrusions are evenly distributed on the surface of the star-shaped wheel body 501 in the circumferential direction, and the star-shaped wheel body 501 is placed inside the built-in rotating cylinder 402, one side of the built-in rotating cylinder 402 is open, one end of the star-shaped 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, the elastic vibration component 502 is provided with a plurality of groups, and each group of elastic vibration components 502 is correspondingly distributed between two adjacent separation push plates 403, and each group of elastic vibration components 502 is Each component 502 includes a plurality of elastic sheets 503 equidistantly distributed along the axial direction of the built-in rotating drum 402. One end of each elastic sheet 503 away from the inner wall of the separating transition cylinder 4 penetrates into the interior of the built-in rotating drum 402 and extends between two adjacent star-shaped protrusions of the star-shaped wheel body 501. When the built-in rotating drum 402 drives the elastic sheet 503 to rotate, the extending end of the elastic sheet 503 extending between the star-shaped protrusions will successively squeeze the star-shaped protrusions on the star-shaped wheel body 501 during the rotation process, and then rebound and vibrate, thereby generating a vibration effect on the blast furnace gas in the reaction chamber. In addition, each group of elastic vibration components 502 is also provided with an elastic block 504 at the corresponding position where each elastic sheet 503 penetrates the built-in rotating drum 402.

[0030] It should be noted that the star wheel body 501 is a star-shaped structure with multiple star-shaped protrusions distributed circumferentially on the surface, and the distribution density of the star-shaped protrusions can be selected according to actual needs. Since the star wheel body 501 is fixed relative to the separation transition tube 4, and the elastic vibration component rotates with the built-in rotating drum 402, then during the rotation of the built-in rotating drum 402, one end of the elastic sheet 503 in each group of elastic vibration components squeezes the star-shaped protrusion position of the star wheel body 501 one by one, and then the elastic sheet 503 is deformed and rebounds and vibrates, so that the entire elastic vibration component vibrates, and then the blast furnace gas in the corresponding reaction chamber vibrates, so that the movement degree of the blast furnace gas is enhanced, so as to fully contact and react with the reaction liquid, and improve the desulfurization effect. In addition, due to the vibration of the vibration mechanism 5, the movement intensity of the blast furnace gas can still be enhanced even when the built-in rotating drum 402 is at a slower speed, and the built-in rotating drum 402 is at a slower speed. The situation that the blast furnace gas exists in the reaction chamber inside the separation transition tube 4 for a long time, further ensuring the desulfurization reaction.

[0031] At this point, the structural basis for the operation of blast furnace gas and the specific location basis for the desulfurization reaction are obtained.

[0032] In addition, the reaction liquid required for the desulfurization reaction of blast furnace gas is provided by the reaction liquid storage mechanism 2 and the liquid delivery mechanism 3. Figure 2 As 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 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 supplying the reaction liquid to the inside of the liquid storage cylinder 201 is installed on the top of the liquid storage cylinder 201.

[0033] like Figure 1-3 As shown, the liquid delivery mechanism 3 is arranged below the liquid storage cylinder 201, and the liquid delivery mechanism 3 includes a piston cylinder 301, which is connected to the first one-way valve 202 and is used to receive the reaction liquid inside the liquid storage cylinder 201. One end of the piston cylinder 301 is connected to the interior of the desulfurization tower body 1 through a liquid outlet conduit 302, and one end of the liquid outlet conduit 302 located inside the desulfurization tower body 1 is connected to a plurality of atomizing nozzles 304 through a plurality of hoses 303, and the plurality of atomizing nozzles 304 are evenly spaced on the circumferential side wall of the separation transition cylinder 4. In addition, a second one-way valve is also provided on the liquid outlet conduit 302, which is used to output the reaction liquid in the piston cylinder 301 to the atomizing nozzle 304 in a one-way manner and then spray it into the reaction chamber.

[0034] On this basis, a piston block 305 is provided in an internal sliding fit of the piston cylinder 301, and 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.

[0035] like Figure 1 , Figure 8 As shown, the power transmission mechanism 7 includes a main gear 701 fixed on the first rotating shaft 603, a sub-gear 703 rotated on the outer wall of the desulfurization tower body 1 through the second rotating shaft 702, and a first steering bevel gear 704 fixed on the end of the second rotating shaft 702, wherein the main gear 701 is meshed with the sub-gear 703. In addition, the power transmission mechanism 7 also includes a second steering bevel gear 705 meshed with the first steering bevel gear 704. In this embodiment, the second steering bevel gear 705 is used to redirect the power transmitted by the power transmission mechanism 7 to the reciprocating push-pull mechanism 8.

[0036] The reciprocating push-pull mechanism 8 includes an axis frame 801 arranged on one side of the piston cylinder 301, and one end of the axis frame 801 is fixed on the support frame 203, and the other end of the axis frame 801 is rotatably connected to the middle part of the third rotating shaft 802, one end of the third rotating shaft 802 is fixedly connected to the second connecting 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 connecting rod 803 is rotatably connected to one end of the first connecting rod 804 through a rotating pin, and the other end of the first connecting rod 804 is rotatably connected to one end of the push-pull rod 805 through a rotating pin, and the end of the push-pull rod 805 away from the first connecting rod 804 is fixedly connected to the piston block 305.

[0037] It should be noted that when the power assembly 6 drives the transmission assembly to move, the components in the power transmission mechanism 7 and the reciprocating push-pull mechanism 8 do not interfere with each other.

[0038] Based on the above embodiment, when the motor 602 drives the rotating partition 404 to rotate, the motor 602 also drives the main gear 701 to rotate, and the main gear 701 drives the sub-gear 703 to rotate. At this time, the first steering bevel gear 704 and the sub-gear 703 rotate synchronously on the same axis, 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 follows the second steering bevel gear 705 to make a circular motion with the third rotating shaft 802 as the axis; during the circular motion of the second linkage rod 803, the end thereof away from the second steering bevel gear 705 reciprocates and drives the push-pull rod 803 through the first linkage rod 804. 5. In 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 draws a certain amount of reaction liquid from the liquid storage cylinder 201 through the first one-way valve 202. When the piston block 305 begins to approach the liquid outlet conduit 302, it squeezes the reaction liquid in the piston cylinder 301. In this process, the reaction liquid can only flow out of the liquid outlet conduit 302 through the second one-way valve 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.

[0039] It should also be noted that the reaction liquid described in the present application can be an alkaline solution, such as a sodium hydroxide solution, and based on the chemical properties of the reaction liquid, the various components disclosed in the present invention that are in direct contact with the reaction liquid are made of materials that do not react with it, for example, the elastic sheet 503 and the elastic block 504 in the present application are made of polytetrafluoroethylene; and 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 reaction liquid injected each time reaches a sufficient amount, thereby ensuring that a sufficient amount of reaction liquid is sprayed into the separation transition cylinder 4, and because the multiple atomizing nozzles 304 are evenly spaced and distributed on the side wall of the separation transition cylinder 4, when the rotating partition is at a slower speed, the blast furnace gas in each reaction chamber can be sprayed multiple times, thereby ensuring the reaction effect.

[0040] In order to facilitate those skilled in the art to understand the embodiments of the present invention, the working principle of the present invention is briefly described in combination with specific application scenarios: When desulfurizing blast furnace gas by using the liquid spray device for the blast furnace gas desulfurization tower provided by the present invention, 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 opening 401 on the lower side of the separation transition tube 4, and enters different reaction chambers in the process of rotation of the rotating partition. At this time, the blast furnace gas slowly moves toward the opening 401 on the upper side of the separation transition tube 4 in the reaction chamber.

[0041] During the rotation of the rotating partition, the power component 6 also drives the transmission component to move. At this time, the reciprocating push-pull mechanism 8 cooperates with the liquid feeding mechanism 3 to feed the reaction liquid in the liquid storage cylinder 201 into the separation transition cylinder 4, and the atomizing nozzle 304 atomizes the reaction liquid and sprays it into each reaction chamber, so that the blast furnace gas in each reaction chamber can fully react with the reaction liquid; in order to improve the reaction effect, the present invention also arranges a vibration mechanism 5 on the rotating partition. While the power component 6 provides rotational power for the rotating partition, the blast furnace gas in the reaction chamber is vibrated through the cooperation of the star wheel body 501 and the elastic vibration component, so that it can fully contact and react with the atomized reaction liquid, thereby improving the reaction effect.
