[0022] As Figures 1-3 The utility model discloses a kind of supply devices of high-activity desulfurizer, including supply bin 1, the top of supply bin 1 is equipped with feed inlet 2 and driving motor 3, the output end of driving motor 3 extends branch supply bin 1 inside and is connected with stirring shaft 4, stirring shaft 4 is equipped with stirring assembly, stirring assembly includes stirring blade 13 and stirring plate 14, stirring blade 13 and stirring plate 14 are arranged on and connect on stirring shaft 4, stirring plate 14 is curved shape structure, stirring blade 13 can quickly scatter desulfurizer powder, so that high-activity desulfurizer powder is more uniform, and stirring plate 14 can further promote powder, and desulfurizer powder can be constantly pushed into discharge part 6 by centrifugal force. This not only improves the efficiency of material conveying, but also ensures that material can be uniformly and stably entered into next processing link.

[0023] The right side of the supply bin 1 is internally provided with a discharging inner tube 5, the bottom of the discharging inner tube 5 is provided with a discharging part 6 between the right side bottom of the supply bin 1, the right side of the supply bin 1 is externally provided with a discharging outer tube 7, the discharging inner tube 5 is in communication with the discharging outer tube 7, the right side bottom of the supply bin 1 is provided with a piston tube 8, and the discharging part 6 is located at the interval between the piston tube 8 and the discharging inner tube 5. The piston tube 8 is coaxially arranged with the discharging inner tube 5, and the lower part of the piston tube 8 is provided with a hydraulic cylinder 9, the output end of the hydraulic cylinder 9 is connected with an output shaft 10, the output shaft 10 extends into the piston tube 8 and is connected with a piston 11, and the top of the piston 11 is provided with a bevel structure 12. The piston 11 realizes reciprocating motion between the piston tube 8 and the top of the discharging inner tube 5 under the action of the cylinder. Under the action of the stirring plate 14, the high-activity desulfurizer powder is accumulated in the discharging part 6, and then the piston 11 moves upward to move the high-activity desulfurizer powder to the communication position of the discharging inner tube 5 and the discharging outer tube 7. Due to the bevel structure 12 at the top of the piston 11, the high-activity desulfurizer powder automatically enters the discharging outer tube 7 and falls into the slurry pool at the bottom of the tower under the action of gravity. The design of the bevel structure 12 avoids the blockage of the powder at the discharging port, and ensures that the desulfurizer powder can smoothly enter the discharging outer tube 7. Due to the accumulation of the high-activity desulfurizer powder in the discharging part 6, a relatively stable high-activity desulfurizer powder layer is formed, and when the piston 11 moves upward, the high-activity desulfurizer powder in this layer is pushed to the discharging inner tube 5, so that the quantitative delivery of the high-activity desulfurizer powder can be realized.

[0024] The top of the piston 11 is further connected with a limiting rod 22, the top of the limiting rod 22 is connected with a limiting piston 23, and the limiting piston 23 is connected to the upper part of the piston 11 through the limiting rod 22, so as to be separated from the upper part of the piston 11 by a predetermined distance, thereby further limiting the delivery amount of the high-activity desulfurizer powder. The presence of the limiting piston 23 ensures that the desulfurizer powder will not be excessively delivered into the discharging inner tube 5 when the piston 11 moves upward, thereby realizing accurate control of the delivery amount of the desulfurizer powder.

[0025] In combination Figure 1 And Figure 4The inside of the supply bin 1 is provided with a temperature sensor 15, the bottom of the supply bin 1 is provided with a heating resistor 16, and the side wall of the supply bin 1 is provided with a cooling assembly, which comprises a cooling plate 17 provided with a serpentine cooling circulating water channel 18. The desulfurizer temperature inside the supply bin 1 can be monitored in real time through the temperature sensor 15, so that the high-activity desulfurizer can always be kept within the optimal working temperature range. This helps to improve the activity and reaction efficiency of the high-activity desulfurizer, thereby improving the desulfurization effect. The heating resistor 16 enables the supply bin 1 to preheat the high-activity desulfurizer in a low-temperature environment, ensuring that the high-activity desulfurizer reaches a suitable reaction temperature before entering the reaction zone. At the same time, the cooling assembly can cool the high-activity desulfurizer in a high-temperature environment, preventing the high-activity desulfurizer from being degraded or failing due to excessive temperature. This temperature adjustment capability enables the supply device to adapt to the working condition requirements under different temperature conditions. The cooling assembly adopts a serpentine cooling circulating water channel 18 design, which can effectively improve the cooling efficiency and reduce energy consumption.

[0026] In combination Figure 3 The piston 11 is provided with a Y-shaped sealing ring 19 and a hole seal 20, and a guide belt 21 is also installed between the Y-shaped sealing ring 19 and the hole seal 20.

The Y-shaped sealing ring 19 has a unique shape design, which can provide good sealing effect under high pressure and effectively prevent the leakage of desulfurizer powder. The hole seal 20 has excellent wear resistance and chemical resistance, further enhancing the sealing performance and ensuring that the piston 11 maintains stable sealing effect during long-term operation. The installation of the guide belt 21 helps to reduce the friction and wear of the piston 11 during movement. The guide belt 21 can ensure that the piston 11 moves smoothly and smoothly in the piston pipe 8, reducing the heat and wear generated by friction, thereby prolonging the service life of the piston 11.
