[0002] The sodium bicarbonate dry desulfurization process uses sodium bicarbonate as a desulfurizing agent and can be widely used in the field of flue gas dry purification, such as in coal-fired power plants, waste or alternative fuel incineration plants. It can also be widely used in industrial waste gases containing acidic substances, such as those from glass, biomass combustion, cement, and metallurgy. In use, finely ground sodium bicarbonate ultrafine powder is placed in the reaction tower and reacts with SO2 in the flue gas to generate desulfurization ash, which can effectively remove more than 95% of SO2 from the tail gas. The reacted gas is discharged through the flue.

[0003] The desulfurization device disclosed in patent CN210434275U has drawbacks during use. The desulfurizing agent is piled up inside the device, resulting in insufficient reaction of the desulfurizing agent inside, which easily leads to waste. At the same time, the operating temperature is inconsistent, and the reaction rate is low. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-2 A sodium bicarbonate dry desulfurization device includes a reactor 1, a bottom furnace 2, a top cover 3, and a chimney 4. The top cover 3 and the bottom furnace 2 are installed on the upper and lower sides of the reactor 1, respectively. A chimney 4 and a flue gas inlet are respectively provided on one side of the top cover 3 and the bottom furnace 2. A desulfurization plate 5 is inserted into the side wall of the reactor 1. Supports 6 are provided on both sides of the inner wall of the reactor 1. A heating pipe 7 is provided at the bottom of the top cover 3.

[0025] The reactor 1 has mounting holes on its side, which slide against the desulfurization plate 5. The bottom and side walls of the desulfurization plate 5 slide against the top and side surfaces of the support 6.

[0026] according to Figure 3 As shown, the desulfurization disc 5 includes an installation disc 51, a pull handle 52, and a vibrating disc 53. The installation disc 51 has an installation groove inside, the vibrating disc 53 is movably disposed on the inner wall of the installation groove, and the pull handle 52 is fixedly disposed on the outer side of the installation disc 51.

[0027] By sliding the desulfurization disc 5 against the support 6, the desulfurization disc 5 can be separated from the reactor 1 and installed. After the desulfurization process of sodium bicarbonate is completed, the desulfurization disc 5 can be removed to maintain and clean it, so that the impurities remaining in the desulfurization disc 5 from the previous desulfurization process will not affect the efficiency and quality of desulfurization in the next sodium bicarbonate desulfurization process.

[0028] according to Figure 3-4 As shown, auxiliary blocks 54 are provided on both sides of the vibratory plate 53. The auxiliary blocks 54 are slidably disposed with the side wall of the mounting groove. A connecting frame 55 is provided on the top surface of the mounting plate 51. A spring 56 is provided on the bottom surface of the connecting frame 55. A support rod 58 is fixedly disposed on the bottom surface of the connecting frame 55. A drive motor 59 is provided on the bottom surface of the bracket 6. A transmission roller is provided on the output shaft of the drive motor 59. An impact block 510 is fixedly disposed on the outer wall of the transmission roller. An impact block 57 is provided below the vibratory plate 53.

[0029] There are six auxiliary blocks 54. The six auxiliary blocks 54 are symmetrically distributed in groups of three on both sides of the vibrating plate 53 and slide against the mounting groove. The top surface of the auxiliary block 54 is provided with a movable hole. The connecting frame 55 is located above the movable hole. The spring 56 is located on the opposite side of the auxiliary block 54 and the connecting frame 55. The support rod 58 passes through the movable hole and is located below the bracket 6. The support rod 58 is located inside the spring 56. The bottom of the impact block 57 is provided with a trapezoidal block. The two sides of the trapezoidal block abut against the top of the impact block 510.

[0030] During use, the desulfurization disc 5 allows the vibratory disc 53 to vibrate up and down on the inner wall of the mounting groove. This vibration agitates the desulfurizing agent on the surface of the vibratory disc 53, improving the contact between the flue gas and the desulfurizing agent, thus increasing desulfurization efficiency and quality, and enhancing reaction efficiency. The heating pipe 7 ensures the temperature inside the reactor 1 is at its optimal reaction temperature, further improving reaction efficiency. Specifically, the vibration of the vibratory disc 53 is achieved by starting the drive motor 59, which rotates the transmission roller. This rotation of the transmission roller, in turn, rotates the striking block 510. As the striking block 510 rotates, when the striking block 510… When the head of the impact block 510 rotates to the side of the impact block 57, it continues to rotate, pushing the impact block 57 upward. During this process, as the impact block 57 moves upward, it can drive the vibratory plate 53 to move, causing the vibratory plate 53 and the auxiliary block 54 to move upward on the inner wall of the mounting groove and compress the spring 56. When the head of the impact block 510 leaves the bottom of the impact block 57, the auxiliary block 54 is rebounded by the spring 56 and moves downward, thereby driving the vibratory plate 53 to move downward on the inner wall of the mounting groove until the vibratory plate 53 is in the initial position. With the continuous rotation of the impact block 510, the reciprocating movement of the vibratory plate 53 can be realized, thereby achieving the purpose of vibrating and turning the desulfurizing agent.

[0031] In summary, this sodium bicarbonate dry desulfurization device, through the sliding contact between the desulfurization disc 5 and the support 6, enables the separation and installation of the desulfurization disc 5 and the reactor 1. After the sodium bicarbonate desulfurization process is completed, the desulfurization disc 5 can be removed for maintenance and cleaning, preventing residual impurities from affecting the efficiency and quality of desulfurization in subsequent sodium bicarbonate desulfurization processes. The desulfurization disc 5 allows the vibrating disc 53 to vibrate up and down on the inner wall of the mounting groove. With vibration, the desulfurizing agent on the surface of the vibrating disc 53 can be agitated, thereby improving the full contact between the flue gas and the desulfurizing agent, improving the efficiency and quality of desulfurization, and increasing the reaction efficiency. By setting the heating tube 7, the internal temperature of the reactor 1 is kept as close as possible to the optimal reaction temperature, further improving the reaction efficiency.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
