It includes a tower body with a rotatable liquid-throwing plate at its top, from which rich desulfurization liquor is injected; a drive mechanism to drive the liquid-throwing plate to rotate; a splash plate disposed on the inner wall of the tower body; and a blower mechanism to blow air into the tower body.

Description

Technical Field

[0001] This utility model relates to the technical field of rich liquor regeneration devices, specifically a desulfurization rich liquor regeneration device for wet desulfurization. Background Technology

[0002] A desulfurization rich liquor regeneration unit is a specialized device for treating desulfurization rich liquor. Through a series of chemical reactions and physical separation processes, it converts sulfides in the rich liquor into elemental sulfur, restoring its desulfurization capacity. Its working principle typically involves two processes: chemical oxidation and physical separation. In the chemical oxidation stage, the rich liquor comes into contact with air or oxygen, and the sulfides in the rich liquor are oxidized into elemental sulfur through a chemical reaction. In the physical separation stage, the sulfur foam formed after oxidation is separated from the desulfurization liquor through physical methods such as flotation and filtration, forming sulfur paste or sulfur products.

[0003] The utility model with announcement number CN222151529U discloses a regeneration tower that can fully desulfurize rich liquor. This utility model sprays the rich liquor outward through nozzles, which can diffuse the volume of the rich liquor and increase the contact area between the rich liquor and steam. The steam is drawn into the regeneration tower body by the exhaust fan, which can accelerate the flow rate of the steam and slow down the descent rate of the rich liquor. This facilitates the full desulfurization of the rich liquor by steam and reduces the height of the regeneration tower, thereby reducing the manufacturing cost of the regeneration tower.

[0004] In the above-mentioned scheme, although the rich liquid can be pressurized and sprayed out in the form of mist through the nozzle, thereby ensuring that the rich liquid can fully react with the air, the amount of water mist that the nozzle can output per unit time is limited. If a large amount of rich liquid needs to be processed in a short time, multiple nozzles need to be added, which will lead to a surge in costs. In addition, the rich liquid may contain impurities, which can easily cause nozzle blockage and make it difficult to work continuously and efficiently for a long time. Therefore, in order to address the above problems, a desulfurization rich liquid regeneration device for wet desulfurization is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a rich liquid regeneration device for wet desulfurization. This device has a rotatable liquid-throwing plate mounted at the top of the tower body. Driven by a mechanism, the plate rotates at high speed, and the rich liquid injected into it is thrown out by centrifugal force, accelerating along the liquid tank. When the rich liquid leaves the tank, it has a high velocity, and upon impacting the splash plate, it forms a liquid mist due to its large kinetic energy, effectively atomizing the rich liquid. This allows the rich liquid to fully react with the air or oxygen supplied by the blower mechanism. Furthermore, the liquid-blocking mesh plate blocks the rich liquid, extending its time in the air. This technical solution can process a large amount of rich liquid per unit time, is less prone to impurity blockage, and can operate continuously for extended periods. The structure is simple and has low operating costs. This solves the technical problems of comparative technologies, such as the limited water mist output per unit time of the nozzles, making it difficult to process large amounts of rich liquid in a short time, and the clogging of nozzles by impurities in the rich liquid, hindering long-term continuous and efficient operation.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A wet desulfurization rich liquor regeneration device includes a tower body with a rotatable liquid-throwing plate at its top. The rich desulfurization liquor is injected from the top of the liquid-throwing plate. A drive mechanism is located below the liquid-throwing plate to drive its rotation. A splash plate is located on the inner wall of the tower body and sleeved around the liquid-throwing plate. A blower mechanism is located below the liquid-throwing plate to blow air into the tower body. A liquid-blocking mesh plate is installed below the blower mechanism. The liquid-throwing plate includes an umbrella-shaped plate with several sets of circumferentially arranged slotted plates fixed on it. Each set of slotted plates forms a liquid tank. An inlet cylinder communicating with the liquid tank is installed in the center of the umbrella-shaped plate. The umbrella-shaped plate can be driven by the drive mechanism to achieve high... The high-speed rotation causes the rich liquid injected into the inlet cylinder to be thrown out under centrifugal force and accelerate along the liquid tank. When the rich liquid leaves the liquid tank, it has a high speed, so when it hits the splash plate, it will fully form a liquid mist due to its large kinetic energy, which will atomize the rich liquid. This allows the rich liquid to fully react with the air or oxygen supplied by the blower mechanism. The liquid blocking mesh plate can also block the rich liquid and prolong its time in the air. The above technical solution can process a large amount of rich liquid per unit time and is not prone to impurity blockage. It can work continuously for a long time, and the structure is simple and has low operating cost.

[0008] In one possible implementation, the top of the tower body is provided with a top cylinder, inside which several connecting bearings are fixedly installed. The inner ring of the connecting bearings is fixedly connected to the outer wall of the liquid inlet cylinder. The above structure can realize the rotatable connection between the liquid inlet cylinder and the top of the tower body, realize the rotatable installation of the liquid slinging plate as a whole, and ensure the stability of the installation. At the same time, a liquid injection pipe connected to the liquid inlet cylinder is installed on the top cylinder, which is used to inject rich liquid into the liquid inlet cylinder.

[0009] In one possible implementation, the bottom of the liquid inlet cylinder has several liquid guide ports arranged in a circumferential array, and each liquid guide port is connected to a corresponding liquid tank. The liquid guide ports can guide the rich liquid in the liquid inlet cylinder into the corresponding liquid tank, so that it can accelerate under the action of centrifugal force. At the same time, the liquid inlet cylinder is provided with a reinforcing member with a through groove. The setting of the reinforcing member can enhance the structural strength of the bottom of the liquid inlet cylinder and avoid the structural load-bearing capacity of the opening of the liquid guide ports being insufficient and easy to break.

[0010] In one possible implementation, the splash plate includes an annular plate with a baffle ring fixedly disposed at its top end, and a number of outwardly protruding splash ridges fixedly disposed on its inner wall. The baffle ring can prevent the impact-atomized rich liquid from drifting downward as much as possible, and the splash ridges can enhance the impact atomization effect on the rich liquid.

[0011] In one possible implementation, the blower mechanism includes an annular duct, which is fixedly installed on the inner wall of the tower body by a suspension rod at the top. Several sets of air outlets are arranged in a circular array on the lower side of the annular duct. At the same time, an air inlet pipe is sealed to the annular duct, the end of which extends out of the tower body and is connected to an external blower. The airflow sent by the blower enters the annular duct through the air inlet pipe and is evenly sent out through the air outlets, making full contact with and reacting with the atomized rich liquid.

[0012] In one possible implementation, the liquid-blocking mesh is composed of multiple layers of metal mesh stacked alternately at a fixed deflection angle. This structure allows the liquid-blocking mesh to form dense and interlaced through holes, enabling the rich liquid to flow irregularly within it, thereby prolonging its dwell time, i.e., prolonging its contact time with air, and ensuring the reaction effect.

[0013] In one possible implementation, the drive mechanism includes a waterproof housing with a drive motor installed inside. The output shaft of the drive motor is connected to the bottom of the liquid-throwing tray. In addition, the waterproof housing is fixedly connected to the inner wall of the tower via a support rod installed thereon. The above structure can complete the fixed installation of the drive motor while ensuring its waterproofness.

[0014] In one possible implementation, the bottom of the tower is hermetically connected to a liquid outlet, through which the fully reacted rich liquid flows out, and the top of the tower is hermetically connected to an air outlet, through which the air that has undergone the reaction flows out.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] The rich liquid regeneration device has a rotatable liquid-throwing plate mounted on the top of the tower. Driven by a mechanism, the plate rotates at high speed, and the rich liquid injected into it is thrown out by centrifugal force, accelerating along the liquid tank. When the rich liquid leaves the tank, it has a high velocity, and when it impacts the splash plate, it forms a liquid mist due to its large kinetic energy, effectively atomizing the rich liquid. This allows the rich liquid to fully react with the air or oxygen supplied by the blower mechanism. Furthermore, the liquid-blocking mesh plate blocks the rich liquid, extending its time in the air. This technical solution can process a large amount of rich liquid per unit time, is less prone to impurity blockage, can operate continuously for extended periods, and has a simple structure with low operating costs.

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0024] like Figure 1 - Figure 2As shown in this embodiment, a wet desulfurization rich liquor regeneration device includes a tower body 1, with a rotatable liquid-throwing plate 2 rotatably mounted on its top. The desulfurization rich liquor is injected from the top of the liquid-throwing plate 2. A driving mechanism 3 is located on the lower side of the liquid-throwing plate 2 to drive its rotation. A splashing plate 4 is located on the inner wall of the tower body 1 and sleeved on the outside of the liquid-throwing plate 2. A blower mechanism 5 is located on the lower side of the liquid-throwing plate 2 to blow air into the tower body 1. A liquid-blocking mesh plate 6 is installed on the lower side of the blower mechanism 5. The liquid-throwing plate 2 includes an umbrella-shaped plate 21, on which several sets of grooved plates 22 arranged in a circumferential array are fixed. Each set of grooved plates 22 encloses a liquid tank 221. An inlet cylinder 23 communicating with the liquid tank 221 is installed in the middle of the umbrella-shaped plate 21. 21 can rotate at high speed under the action of the drive mechanism 3. The rich liquid injected into the liquid inlet cylinder 23 will be thrown out under the action of centrifugal force and accelerate along the liquid tank 221. When the rich liquid leaves the liquid tank 221, it has a high speed. Therefore, when it hits the splash plate 4, it will fully form liquid mist due to the large kinetic energy, which will atomize the rich liquid. This allows the rich liquid to fully react with the air or oxygen sent in by the blower mechanism 5. The liquid blocking mesh plate 6 can block the rich liquid and prolong its time in the air. The above technical solution can process a large amount of rich liquid per unit time and is not prone to impurity blockage. It can work continuously for a long time. Moreover, the above structure is simple and has a low operating cost.

[0025] like Figure 1 As shown, the top of the tower body 1 is provided with a top cylinder 11, and several connecting bearings 12 are fixedly installed inside it. The inner ring of the connecting bearing 12 is fixedly connected to the outer wall of the liquid inlet cylinder 23. The above structure can realize the rotatable connection between the liquid inlet cylinder 23 and the top of the tower body 1, realize the overall rotatable installation of the liquid slinging plate 2, and ensure the stability of the installation. At the same time, a liquid injection pipe 13 connected to the liquid inlet cylinder 23 is installed on the top cylinder 11. The liquid injection pipe 13 is used to inject the rich liquid into the liquid inlet cylinder 23.

[0026] like Figure 2 - Figure 3 As shown, the bottom of the liquid inlet cylinder 23 has several liquid guide ports 233 arranged in a circular array, and each liquid guide port 233 is connected to its corresponding liquid tank 221. The liquid guide ports 233 can guide the rich liquid in the liquid inlet cylinder 23 into the corresponding liquid tank 221, so that it can accelerate under the action of centrifugal force. At the same time, the liquid inlet cylinder 23 is provided with a reinforcing member 231, which has a through groove 232. The setting of the reinforcing member 231 can enhance the structural strength of the bottom of the liquid inlet cylinder 23 and prevent the structure from being easily broken due to insufficient load-bearing capacity caused by the opening of the liquid guide ports 233.

[0027] The splash plate 4 includes an annular plate 41 with a baffle ring 42 fixedly installed at its top and several outwardly protruding splash ridges 43 fixedly installed on its inner wall. The baffle ring 42 can prevent the impact-atomized rich liquid from drifting downward as much as possible, and the splash ridges 43 can enhance the impact atomization effect on the rich liquid.

[0028] like Figure 4 As shown, the blower mechanism 5 includes an annular air duct 51, which is fixedly installed on the inner wall of the tower body 1 by a suspension rod 54 provided at the top. Several sets of air outlet holes 52 arranged in a circular array are opened on the lower side of the annular air duct 51. At the same time, an air inlet pipe 53 is sealed and connected to the annular air duct 51, the end of which extends out of the tower body 1 and is connected to the external blower equipment. The airflow sent by the blower equipment enters the annular air duct 51 through the air inlet pipe 53 and is evenly sent out through the air outlet holes 52, so as to fully contact and react with the atomized rich liquid.

[0029] like Figure 1 As shown, the liquid blocking mesh plate 6 is composed of multiple layers of metal mesh plates stacked alternately at a fixed deflection angle. The above structure allows the liquid blocking mesh plate 6 to form dense and interlaced through holes, which allows the rich liquid to flow irregularly in it, thereby prolonging its residence time, that is, prolonging its contact time with air and ensuring the reaction effect.

[0030] like Figure 2 As shown, the drive mechanism 3 includes a waterproof housing 31, inside which a drive motor 32 is installed. The output shaft of the drive motor 32 is connected to the bottom of the liquid-throwing tray 2. In addition, the waterproof housing 31 is fixedly connected to the inner wall of the tower body 1 through a support rod 33 installed on it. The above structure can complete the fixed installation of the drive motor 32 and ensure its waterproofness.

[0031] like Figure 1 As shown, the bottom of the tower body 1 is sealed with a liquid outlet 71, through which the fully reacted rich liquid flows out. The top of the tower body 1 is sealed with a gas outlet 72, through which the air that has undergone the reaction flows out.

[0032] The working principle and usage process of this utility model:

[0033] The rich liquid regeneration device has a rotatable liquid-throwing plate 2 mounted on the top of the tower body 1. It can rotate at high speed under the action of the drive mechanism 3. The rich liquid injected into the liquid-throwing plate 2 will be thrown out under the action of centrifugal force and accelerate along the liquid tank 221. When the rich liquid leaves the liquid tank 221, it has a high speed. Therefore, when it hits the liquid-splashing plate 4, it will fully form liquid mist due to the large kinetic energy, which will atomize the rich liquid. This allows the rich liquid to fully react with the air or oxygen supplied by the blower mechanism 5. The liquid-blocking mesh plate 6 can block the rich liquid and prolong its time in the air. The above technical solution can process a large amount of rich liquid per unit time and is not prone to impurity blockage. It can work continuously for a long time. Moreover, the above structure is simple and has a low operating cost.

[0034] The blower mechanism 5 includes an annular duct 51, which is fixedly installed on the inner wall of the tower body 1 by a suspension rod 54 set at the top. Several sets of air outlet holes 52 arranged in a circular array are opened on the lower side of the annular duct 51. At the same time, an air inlet pipe 53 is sealed and connected to the annular duct 51, the end of which extends out of the tower body 1 and is connected to the external blower equipment. The airflow sent by the blower equipment enters the annular duct 51 through the air inlet pipe 53 and is evenly sent out through the air outlet holes 52, so as to fully contact and react with the atomized rich liquid.

[0035] The liquid blocking mesh plate 6 is composed of multiple layers of metal mesh plates stacked alternately at a fixed deflection angle. This structure allows the liquid blocking mesh plate 6 to form dense and interlaced through holes, which allows the rich liquid to flow irregularly within it, thereby prolonging its residence time, that is, prolonging its contact time with air and ensuring the reaction effect.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
