Abstract
Description
A power plant desulfurization slurry preparation and storage device Technical Field
[0001] This application relates to the field of desulfurization slurry preparation technology, and more specifically, to a power plant desulfurization slurry preparation and storage device. Background Technology
[0002] In modern industrial production, especially in thermal power plants, emissions of harmful gases such as sulfur dioxide from coal combustion have become one of the main sources of environmental pollution. To reduce the damage these pollutants cause to the atmosphere, power plants have widely adopted desulfurization technologies, among which wet desulfurization is widely used due to its high desulfurization efficiency. The core of wet desulfurization lies in the preparation and supply of desulfurization slurry. Existing desulfurization slurry preparation systems have some significant shortcomings in actual operation, which limit desulfurization efficiency and the overall performance of the system.
[0003] Existing desulfurization slurry preparation methods typically involve preparing a fixed amount of slurry at a time and then supplying it to the desulfurization tower. A major problem with this method is that the slurry supply is intermittent, not continuous. Specifically, the desulfurization slurry is usually a mixture of limestone powder and water, and this slurry needs to be immediately transported to the desulfurization tower after preparation. However, since the amount of slurry prepared each time is limited, the preparation process needs to be restarted when the slurry is used up, resulting in an interruption in the slurry supply. This intermittent supply not only affects the continuous operation of the desulfurization tower but may also lead to fluctuations in desulfurization efficiency, thereby affecting the overall emission compliance of the power plant. Summary of the Invention

This device can realize the continuous preparation of desulfurization slurry, thereby improving the impact of existing desulfurization slurry preparation methods on the continuous operation of desulfurization towers and avoiding power plant emissions from failing to meet standards due to fluctuations in desulfurization efficiency.

When closed, the preparation space and the storage space are not connected to each other; when opened, the preparation space and the storage space are connected to each other, allowing the desulfurization slurry to flow into the storage space. The storage space is connected to a slurry output pipe for outputting the desulfurization slurry.

[0012] In one optional embodiment, the linkage assembly includes a first drive shaft, a second drive shaft, a first gear pair, a second gear pair, and a third gear pair; the first drive shaft is rotatably disposed on the partition and perpendicular to the first stirring shaft; the second drive shaft is rotatably disposed on the partition and parallel to the first stirring shaft; the first gear pair is connected between the first drive shaft and the first stirring shaft, and the first gear pair is used to transmit torque to the first drive shaft when the first stirring shaft rotates circumferentially; the second gear pair is connected between the first drive shaft and the second drive shaft, and the second gear pair is used to transmit torque to the second drive shaft when the first drive shaft rotates circumferentially; the third gear pair is connected between the second drive shaft and the second stirring shaft, and the third gear pair is used to transmit torque to the second stirring shaft when the second drive shaft rotates circumferentially.

[0030] Referring to Figures 1 to 4, a power plant desulfurization slurry preparation and storage device is shown. This device can realize the continuous preparation of desulfurization slurry, thereby improving the impact of existing desulfurization slurry preparation methods on the continuous operation of desulfurization towers and avoiding power plant emissions from failing to meet standards due to fluctuations in desulfurization efficiency.
[0031] In some embodiments, a power plant desulfurization slurry preparation and storage device includes a tank 100, a raw material feed pipe disposed at the top of the tank 100, and a slurry output pipe 300 disposed at the bottom of the tank 100. The raw material feed pipe includes a first raw material feed pipe 210 and a second raw material feed pipe 220, which are used for limestone and water (slurry preparation raw materials), respectively. The interior of the tank 100 includes a preparation space 110, a partition 120, and a storage space 130 arranged sequentially from top to bottom. That is, the internal space of the tank 100 is divided into the preparation space 110 and the storage space 130 by the partition 120. The preparation space 110 is connected to the raw material feed pipe, which is used to input the slurry preparation raw materials into the preparation space 110. The slurry preparation raw materials input into the preparation space 110 can be stirred by the stirring assembly 500 to form desulfurization slurry. Specifically, the partition 120 has a through hole and a valve plate 121 disposed in the through hole, which can be closed or opened by the drive assembly 400. When the valve plate 121 is closed, it closes the through hole, preventing the preparation space 110 and the storage space 130 from communicating with each other. When the valve plate 121 is open, it opens the through hole, allowing the preparation space 110 and the storage space 130 to communicate with each other. That is, when desulfurization slurry needs to be prepared, the valve plate 121 can be closed by the drive assembly 400; after the desulfurization slurry preparation is completed, the valve plate 121 can be opened by the drive assembly 400 to allow the prepared desulfurization slurry to flow into and be stored in the storage space 130. The storage space 130 is connected to the slurry output pipe 300, which is used to output the desulfurization slurry. In practical use, the desulfurization slurry prepared in preparation space 110 can be stored in storage space 130 and then output from storage space 130 to desulfurization tower. This allows preparation space 110 to continuously prepare desulfurization slurry, thereby enabling the device itself to continuously supply desulfurization slurry to desulfurization tower. Compared with the intermittent preparation of desulfurization slurry in the existing technology, this can improve the impact of the existing desulfurization slurry preparation method on the continuous operation of desulfurization tower and avoid power plant emissions from failing to meet standards due to fluctuations in desulfurization efficiency.
[0032] In some embodiments, the valve plate 121 is rotatably disposed in the through hole of the partition 120, and the valve plate 121 rotates relative to the partition 120 to open or close. For example, when the valve plate 121 is located in the through hole and on the same plane as the partition 120, the valve plate 121 is in a closed state; when the valve plate 121 rotates 90° clockwise or counterclockwise relative to the partition 120, the valve plate 121 is in an open state. However, the embodiments of this application do not limit this in any way. In other embodiments, the valve plate 121 can also move relative to the partition 120 to open or close.
[0033] In some embodiments, the valve plate 121 is provided with a limiting portion 122, which engages with the partition 120 to limit the rotation angle of the valve plate 121. For example, the limiting portion 122 includes a first limiting half-ring and a second limiting half-ring disposed opposite to each other. The first limiting half-ring is disposed on the edge of a first side of the valve plate 121, and the second limiting half-ring is disposed on the edge of a second side of the valve plate 121. When the valve plate 121 rotates to the closing angle, the first limiting half-ring and the second limiting half-ring engage with the sides of the partition 120 respectively, preventing the valve plate 121 from continuing to rotate in the current direction. Additionally, when the valve plate 121 is in the closed state, the first limiting half-ring and the second limiting half-ring engage with the sides of the partition 120 respectively, preventing the valve plate 121 from opening only by rotating in a single direction (clockwise or counterclockwise). However, this embodiment does not impose any limitations on this.
[0034] In some embodiments, the drive assembly 400 includes a accumulator rod 410 and an accumulator motor 420. The accumulator rod 410 is radially disposed within the tank body 100 and connected to the valve plate 121. The accumulator motor 420 is disposed within the tank body 100 and connected to the accumulator rod 410. The accumulator motor 420 drives the accumulator rod 410 to rotate circumferentially, thereby causing the accumulator rod 410 to drive the valve plate 121 to rotate relative to the partition 120. Specifically, starting the accumulator motor 420 can drive the accumulator rod 410 to rotate circumferentially, and when the accumulator rod 410 rotates circumferentially, it can drive the valve plate 121 to rotate relative to the partition 120, thereby opening or closing the partition 120. However, the embodiments of this application do not limit this in any way.
[0035] In some embodiments, the drive assembly 400 further includes a first bevel gear 430 and a second bevel gear 440. The first bevel gear 430 is disposed on the accumulator rod 410. The second bevel gear 440 is disposed on the drive shaft of the accumulator motor 420, and the second bevel gear 440 meshes with the first bevel gear 430. This configuration allows the accumulator rod 410 and the drive shaft of the motor to form a 90° angle, thereby changing the position of the accumulator motor 420 so that the accumulator motor 420 can be directly mounted on the outer wall of the tank 100. However, this embodiment does not impose any limitations on this.
[0036] In some embodiments, the stirring assembly 500 includes a first stirring assembly 500 and a stirring motor 530. The first stirring assembly 500 includes a first stirring shaft 510 and a first stirring section 520. The first stirring shaft 510 is arranged axially along the tank body 100, and the lower end of the first stirring shaft 510 extends into the tank body 100. The first stirring section 520 is disposed on the first stirring shaft 510 and located within the preparation space 110. The first stirring section 520 may be a frame composed of transverse rods and longitudinal rods. The stirring motor 530 is disposed at the top of the tank body 100 and connected to one end of the first stirring shaft 510 extending out of the tank body 100. The stirring motor 530 is used to drive the first stirring shaft 510 to rotate circumferentially, so that the first stirring shaft 510 drives the first stirring section 520 to stir. Specifically, starting the stirring motor 530 can drive the first stirring shaft 510 to rotate circumferentially. When the first stirring shaft 510 rotates circumferentially, it can drive the first stirring section 520 to rotate, and when the first stirring section 520 rotates, it can stir the pulping raw materials. However, the embodiments of this application do not impose any limitations on this.
[0037] In some embodiments, the stirring assembly 500 further includes a second stirring assembly 500 and a linkage assembly 560. The second stirring assembly 500 includes a second stirring shaft 540 and a second stirring section 550. The second stirring shaft 540 is arranged axially along the tube body and is located within the storage space 130. The second stirring section 550 is disposed on the second stirring shaft 540 and located within the storage space 130, and the second stirring section 550 may be a frame composed of transverse rods and longitudinal rods. The linkage assembly 560 connects the second stirring shaft 540 and the first stirring shaft 510, and the linkage assembly 560 is used to drive the second stirring shaft 540 to rotate circumferentially when the first stirring shaft 510 rotates circumferentially, so that the second stirring shaft 540 drives the second stirring section 550 to stir. Specifically, during the preparation of desulfurization slurry, the first stirring shaft 510 can transmit torque to the second stirring shaft 540 through the linkage assembly 560, so that the second stirring part 550 can stir the desulfurization slurry in the storage space 130. This can prevent the desulfurization slurry from settling in the storage space 130. However, the embodiments of this application do not limit this in any way.
[0038] In some embodiments, the linkage assembly 560 includes a first drive shaft 561, a second drive shaft 562, a first gear pair, a second gear pair, and a third gear pair. The first drive shaft 561 is perpendicular to the first stirring shaft 510 and is rotatably mounted on the partition 120. The second drive shaft 562 is parallel to the first stirring shaft 510 (or the second stirring shaft 540) and is rotatably mounted on the partition 120. The first gear pair connects the first drive shaft 561 and the first stirring shaft 510, and is used to transmit torque to the first drive shaft 561 when the first stirring shaft 510 rotates circumferentially. Specifically, the first gear pair includes a third bevel gear 563 and a fourth bevel gear 564. The third bevel gear 563 is disposed at the lower end of the first stirring shaft 510, and the fourth bevel gear 564 is disposed on the first drive shaft 561 and meshes with the third bevel gear 563. A second gear pair is connected between the first drive shaft 561 and the second drive shaft 562. The second gear pair transmits torque to the second drive shaft 562 when the first drive shaft 561 rotates circumferentially. Specifically, the second gear pair includes a fifth bevel gear 565 and a sixth bevel gear 566. The fifth bevel gear 565 is disposed on the first drive shaft 561, and the sixth bevel gear 566 is disposed on the second drive shaft 562 and meshes with the fifth bevel gear 565. A third gear pair is connected between the second drive shaft 562 and the second stirring shaft 540. The third gear pair transmits torque to the second stirring shaft 540 when the second drive shaft 562 rotates circumferentially. Specifically, the third gear pair includes a first drive gear 567 and a second drive gear 568. The first drive gear 567 is disposed on the second drive shaft 562, and the second drive gear 568 is disposed on the second stirring shaft 540 and meshes with the first drive gear 567. Specifically, in the process of preparing desulfurization slurry, the first stirring shaft 510 can transmit torque to the first drive shaft 561 through the first gear, the first drive shaft 561 can transmit torque to the second drive shaft 562 through the second gear, and the second drive shaft 562 can transmit torque to the second stirring shaft 540 through the third gear. However, this embodiment does not limit this in any way. In other embodiments, the sixth bevel gear 566 can be disposed on the second stirring shaft 540, thus eliminating the need for the second drive shaft 562 and the third gear pair.
[0039] In some embodiments, the two gears of the third gear pair have different speed ratios. For example, one of the first transmission gear 567 and the second transmission gear 568 of the third gear pair is a large gear and the other is a small gear, thus enabling speed change. However, the embodiments of this application do not limit this in any way.
[0040] In some embodiments, the linkage assembly 560 further includes a housing 570, which is fixed to the partition 120. The first drive shaft 561, the second drive shaft 562, the first gear pair, the second gear pair, and the third gear pair are all disposed within the housing 570. This arrangement prevents the components of the linkage assembly 560 from coming into contact with moisture in the desulfurization slurry, thus preventing rust from affecting the transmission effect. However, this application embodiment does not impose any limitations on this.
[0041] The power plant desulfurization slurry preparation and storage device of this application embodiment can store the desulfurization slurry prepared in the preparation space in the storage space, and then output it from the storage space to the desulfurization tower. This allows the preparation space to continuously prepare desulfurization slurry, thereby enabling the device itself to continuously supply desulfurization slurry to the desulfurization tower. Compared with the intermittent preparation of desulfurization slurry in the prior art, this can improve the impact of the existing desulfurization slurry preparation method on the continuous operation of the desulfurization tower and avoid the power plant's emissions from failing to meet standards due to fluctuations in desulfurization efficiency.
