Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, specifically to a desulfurization inclined trough fluidized air device. Background Technology

[0002] In many industrial production sectors such as coal-fired power generation and steel smelting, the combustion process generates a large amount of sulfur-containing waste gas, which will cause serious environmental pollution if directly emitted. Therefore, desulfurization treatment has become an essential part of these industrial production processes, and the efficient delivery of desulfurizing agents is one of the key factors to ensure the stable operation of the desulfurization process.

[0003] The desulfurization chute fluidized bed air system plays a crucial role in the efficient transport of desulfurizing agents during desulfurization processes. Its working principle involves a fan introducing air at a certain pressure and flow rate into the chute. This airflow creates relative movement between the desulfurizing agent particles, achieving a fluidized state. In this state, the desulfurizing agent exhibits fluid-like properties, flowing smoothly within the chute and thus achieving efficient material transport.

[0004] However, existing desulfurization inclined troughs have revealed some problems in actual use. Specifically, due to uneven air distribution or insufficient air pressure, some desulfurizing agent cannot be completely blown away during transportation. This unfluidized desulfurizing agent gradually accumulates at the bottom of the trough. Over time, the accumulated desulfurizing agent not only occupies the effective conveying space within the trough but also hinders the normal flow of other desulfurizing agents. This not only reduces the overall conveying speed of the desulfurizing agent but may also lead to insufficient or uneven supply of desulfurizing agent in the desulfurization process, thereby affecting the desulfurization effect of the entire desulfurization system. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a desulfurization inclined trough fluidized air device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A desulfurization inclined trough fluidizing air device includes a supporting base plate. A desulfurization transport box is rotatably mounted on one end of the supporting base plate via a hinge. The desulfurization transport box has a desulfurization tank inside. A transmission groove is provided on one side of the desulfurization tank. A fluidizing plate is slidably mounted on the top of the transmission groove. Multiple exhaust holes are opened on the surface of the fluidizing plate. A fluidizing fan is installed on one side of the desulfurization transport box. A vibration transport mechanism is provided at the bottom of the fluidizing plate. An angle adjustment mechanism is provided between the supporting base plate and the desulfurization transport box.

[0008] Furthermore, in order to achieve the vibration effect of the fluidized plate, the vibration transport mechanism includes a lifting piston connected to the bottom of the fluidized plate, an air inlet pipe connected to one side of the surface of the transmission groove, a positioning cylinder connected to the top of the air inlet pipe, exhaust holes on both sides of the surface of the positioning cylinder, a telescopic spring connected to the bottom of the lifting piston, and the end of the telescopic spring connected to the inside of the positioning cylinder.

[0009] Furthermore, in order to provide power for the vibration of the fluidizing plate, the lifting piston slides in conjunction with the inner wall of the positioning cylinder, and one end of the air inlet pipe is connected to a drive fan.

[0010] Furthermore, in order to adjust the tilt angle of the desulfurization transport box, the angle adjustment mechanism includes a threaded cylinder connected to the surface of the support base plate, a support screw connected to the internal thread of the threaded cylinder, a support cover rotatably connected to the top of the support screw, and a turning ring connected to one side of the support cover.

[0011] Furthermore, in order to facilitate the discharge of materials after transportation by the desulfurization transport box, a discharge port is opened at one end of the desulfurization transport box.

[0012] Furthermore, in order to load materials into the desulfurization transport box, a feed hopper is installed on one side of the top of the desulfurization transport box.

[0013] Furthermore, in order to achieve soft contact between the top of the support cover and the bottom of the desulfurization transport box, a support pad is connected to the surface of the support cover.

[0014] Furthermore, in order to support the fluidized plate as it descends, a limit ring is connected to one side of the inner wall of the transmission groove.

[0015] Furthermore, to prevent gas and powder from being blown out during feeding, a star-shaped discharge valve is installed at one end of the feed hopper.

[0016] The beneficial effects of this utility model are as follows: By continuously injecting outside air into the desulfurization tank through a fluidizing blower, the gas passes through the fluidizing plate and is evenly blown onto the desulfurizing agent in the desulfurization tank, thereby fluidizing the desulfurizing agent and facilitating its rapid flow and transportation. Simultaneously, the drive motor in the vibration conveying mechanism continuously injects gas into the positioning cylinder, causing the lifting piston in the positioning cylinder to move up and down continuously, thereby generating vibration of the fluidizing plate. This allows the desulfurizing agent that has not been blown up on the surface of the fluidizing plate to be vibrated and transported in the tilted desulfurization tank, effectively preventing the accumulation and blockage of unfluidized desulfurizing agent, and greatly improving the material flowability and conveying efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] According to an embodiment of the present invention, a desulfurization inclined trough fluidized air device is provided.

[0028] like Figures 1-6 As shown, a desulfurization inclined trough fluidizing air device according to an embodiment of the present invention includes a metal rectangular support base plate 1. A desulfurization transport box 2 is rotatably mounted on one end of the support base plate 1 via a hinge. A desulfurization trough 3 is provided on one side of the interior of the desulfurization transport box 2. A transmission trough 4 is provided on the bottom side of the desulfurization trough 3. A fluidizing plate 5 is slidably mounted on the top of the transmission trough 4 for carrying the desulfurization powder to be transported. A plurality of exhaust holes 6 are opened on the surface of the fluidizing plate 5 for gas to enter the desulfurization trough 3 from the transmission trough 4, blowing up the desulfurization powder to achieve fluidization. A fluidizing fan 7 is installed on one side of the desulfurization transport box 2. The exhaust port of the fluidizing fan 7 is installed at one end of the transmission trough 4 for injecting outside air into the transmission trough 4. A vibration transport mechanism 8 is provided at the bottom of the fluidizing plate 5 for continuous vibration of the fluidizing plate 5 during the transport of the desulfurizing agent, increasing the fluidity of the desulfurizing agent. An angle adjustment mechanism 9 is provided between the support base plate 1 and the desulfurization transport box 2 for adjusting the tilt angle of the desulfurization transport box 2.

[0029] like Figures 1-6As shown, the vibrating transport mechanism 8 includes a cylindrical lifting piston 801 connected to the bottom of the fluidized plate 5. An air inlet pipe 802 is connected to one side of the surface of the transmission groove 4. A positioning cylinder 803 is connected to the top of the air inlet pipe 802. Exhaust holes 804 are opened on both sides of the surface of the positioning cylinder 803. A telescopic spring 805 is connected to the bottom of the lifting piston 801. The end of the telescopic spring 805 is connected inside the positioning cylinder 803. The lifting piston 801 slides against the inner wall of the positioning cylinder 803. A drive fan 806 is connected to one end of the air inlet pipe 802. The drive fan 806 passes through the air inlet pipe 802. 02. Gas is injected into the positioning cylinder 803, gradually increasing the air pressure between the positioning cylinder 803 and the lifting piston 801, pushing the lifting piston 801 and the fluidizing plate 5 upward. When one end of the lifting piston 801 moves to the side of the exhaust hole 804, the gas in the positioning cylinder 803 is quickly discharged from the exhaust hole 804, and the internal air pressure decreases rapidly. At this time, the elastic force of the telescopic spring 805 can pull the raised lifting piston 801 and the fluidizing plate 5 downward, thus repeating to achieve the up and down vibration of the fluidizing plate 5; the angle adjustment mechanism 9 includes a support base plate 1 with one side connected to The threaded cylinder 901 has a support screw 902 internally threadedly connected to it. A support cover 903 is rotatably connected to the top of the support screw 902. The top of the support cover 903 contacts the bottom surface of the desulfurization transport box 2. Twisting the support screw 902 changes its support height, thereby adjusting the tilt angle of the desulfurization transport box 2. A hexagonal prism-shaped turning ring 904 is connected to one side of the support cover 903 for facilitating the rotation of the support screw 902. A discharge port 10 is opened at one end of the desulfurization transport box 2 for subsequent discharge of internal transported materials into the desulfurization tower. The desulfurizing agent; a feed hopper 11 is installed on the top side of the desulfurization transport box 2 to facilitate the injection of desulfurizing agent into the desulfurization tank 3; a rubber support pad 12 is connected to the surface of the support cover 903 to achieve soft contact between the top of the support cover 903 and the bottom of the desulfurization transport box 2; a limit ring 13 is connected to one side of the inner wall of the transmission groove 4 to support the fluidized plate 5 after it falls; a star-shaped discharge valve 14 is installed at one end of the feed hopper 11. The star-shaped discharge valve 14 can prevent gas backflow when conveying materials, thereby preventing gas and powder from being blown out when feeding material at the feed inlet.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In actual use, the fluidizing blower 7 and the drive blower 806 are started, and the desulfurizing agent to be transported is continuously fed into the fluidizing plate 5 in the desulfurization tank 3 through the feed hopper 11. The fluidizing blower 7 continuously injects outside air into the desulfurization tank 3, so that the gas passes through the fluidizing plate 5 and is evenly blown onto the desulfurizing agent in the desulfurization tank 3, thereby fluidizing the desulfurizing agent and facilitating its rapid flow and transport. The drive blower 806 injects gas into the positioning cylinder 803 through the air inlet pipe 802, so that the air pressure between the positioning cylinder 803 and the lifting piston 801 gradually increases, pushing the lifting piston 801. As the fluidized plate 5 moves upward, when one end of the lifting piston 801 moves to the side of the exhaust hole 804, the gas in the positioning cylinder 803 is quickly discharged from the exhaust hole 804, and the internal air pressure decreases rapidly. At this time, the elastic force of the telescopic spring 805 can pull the lifted piston 801 and the fluidized plate 5 downward. This repetitive motion causes the fluidized plate 5 to vibrate up and down, thereby enabling the desulfurizing agent that has not been blown off the surface of the fluidized plate 5 to be vibrated and transported in the inclined desulfurization tank 3, and discharged from the discharge port 10 at one end of the desulfurization transport box 2, effectively increasing the fluidity of the desulfurizing agent in the fluidized plate 5.
