Description

Technical Field

[0001] The present invention belongs to the technical field of manganese sulfate preparation, and specifically relates to a device for preparing battery-grade high-purity manganese sulfate by absorbing sulfur dioxide with manganese carbonate ore. Background Art

[0002] Manganese carbonate ore can be used as a desulfurizer in air pollution control. Through its oxidation-reduction property and catalytic activity, it can effectively absorb sulfur dioxide. Moreover, manganese carbonate ore is used in the flue gas desulfurization process, which can not only remove sulfur dioxide in the flue gas but also realize resource utilization, such as producing products like high-purity manganese sulfate and manganese dioxide.

[0003] Currently, in the process of preparing battery-grade high-purity manganese sulfate by absorbing sulfur dioxide with manganese carbonate ore, manganese carbonate ore powder is added as an absorbent in the desulfurization tower to absorb sulfur dioxide in the flue gas. During the absorption process, manganese carbonate reacts with sulfur dioxide to obtain manganese sulfate, and manganese sulfate is obtained as battery-grade high-purity manganese sulfate through a certain purification method. When manganese carbonate absorbs sulfur dioxide in the flue gas, the flue gas is introduced into the manganese carbonate slurry to absorb sulfur dioxide in the flue gas. However, the fluidity of the manganese carbonate slurry in a static state is poor, and it is difficult for the flue gas to come into full contact with the manganese carbonate slurry, resulting in the adsorption capacity of manganese carbonate not being fully exerted, causing a decrease in production capacity and being unfavorable for the efficient preparation of high-purity manganese sulfate. Summary of the Invention

[0004] In order to overcome the above defects, the present invention provides a device for preparing battery-grade high-purity manganese sulfate by absorbing sulfur dioxide with manganese carbonate ore, which solves the problem that when manganese carbonate absorbs sulfur dioxide in the flue gas, the flue gas is introduced into the manganese carbonate slurry to absorb sulfur dioxide in the flue gas. However, the fluidity of the manganese carbonate slurry in a static state is poor, and it is difficult for the flue gas to come into full contact with the manganese carbonate slurry, resulting in the adsorption capacity of manganese carbonate not being fully exerted, causing a decrease in production capacity.

[0005] The object of the present invention is as follows: The motor in the driving component drives the driving wheel to rotate. The driving wheel drives two driven wheels to rotate through a transmission belt, and the driven wheels drive the mixing paddle to rotate through a rotating shaft and stir the manganese carbonate slurry. Cooperating with the guiding and conveying effect of the spiral blade on the manganese carbonate slurry, the fluidity of the manganese carbonate slurry in the material supporting component is improved, so that the manganese carbonate slurry can come into full contact with the flue gas. Since bubbles will be generated in the manganese carbonate slurry during the ventilation process of the air duct, and after the bubbles burst, they can rise from the diversion holes on the material supporting frame, and the pump body works to extract the manganese carbonate slurry from the material supporting frame through the feed pipe. The manganese carbonate slurry falls on the material supporting frame through the discharge pipe and can come into contact with the rising gas again. Therefore, the adsorption effect of the manganese carbonate slurry is improved through a multi-stage absorption method, enabling the adsorption capacity of manganese carbonate to be fully exerted, which is beneficial to the subsequent efficient preparation of high-purity manganese sulfate.

[0009] As a further scheme of the present invention: The air guiding component includes an air guiding pipe. The air guiding pipe is designed in a U shape, and the bottom end of the air guiding pipe is communicated with the wind cavity. The other end of the air guiding pipe is located above the material supporting component. A one-way valve is installed outside the air guiding pipe.

[0010] As a further scheme of the present invention: The material guiding component includes two fixed cylinders. The two fixed cylinders are respectively installed on both sides of the desulfurization tower. A feed valve pipe is installed on one of the fixed cylinders. A discharge valve pipe is installed under the other fixed cylinder. The bottom end of the discharge valve pipe is connected to the manganese sulfate purification device, and the feed valve pipe and the discharge valve pipe are respectively located on both sides of the desulfurization tower.

[0011] As a further scheme of the present invention: A connecting shaft is provided at the lower part inside the material supporting component. The connecting shaft is installed between the two fixed cylinders. A spiral blade is fixedly connected to the outside of the connecting shaft. One end of the connecting shaft penetrates through the fixed cylinder and is fixed to the output shaft of the driving component.

[0012] As a further solution of the present invention: The driving assembly includes a motor, and a fixing plate is provided outside the motor. The fixing plate is fixed on one side of the desulfurization tower. A driving wheel is fixedly connected to the output shaft of the motor. A transmission belt is sleeved outside the driving wheel. Two driven wheels are respectively connected to both sides inside the transmission belt. The driving wheel is in transmission connection with the two driven wheels through the transmission belt.

[0013] As a further solution of the present invention: A rotating shaft is fixedly connected to the side of the driven wheel close to the desulfurization tower. The rotating shaft is installed through the desulfurization tower. A plurality of mixing paddles are fixed outside the rotating shaft. The mixing paddles are located inside the material supporting assembly.

[0014] As a further solution of the present invention: The extraction assembly includes a pump body. The pump body is installed on the back of the desulfurization tower. Two discharge pipes are connected to the top of the pump body. The other ends of the discharge pipes are located above the material supporting assembly. The bottom of the extraction assembly is connected with a feed pipe. The other end of the feed pipe is clamped below one side of the material supporting assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, by placing the manganese carbonate ore powder into the feeding guide assembly, the manganese carbonate ore powder enters the fixed cylinder in the feeding guide assembly. The driving assembly works to drive the connection shaft and the spiral blade to rotate. During the rotation of the spiral blade, the manganese carbonate ore powder is sent into the material supporting assembly. The spray pipe is connected to a water source to supply water into the desulfurization tower, so that the water contacts the manganese carbonate ore powder in the desulfurization tower and is mixed through the driving assembly to form manganese carbonate slurry, and the manganese carbonate slurry submerges the end of the air guide pipe. Secondly, the flue gas containing sulfur dioxide is introduced into the air cavity through the intake pipe, and the flue gas is introduced into the manganese carbonate slurry in the material supporting assembly through the air guide pipe, so that the manganese carbonate slurry can contact the flue gas containing sulfur dioxide and absorb sulfur dioxide. The motor in the driving assembly drives the driving wheel to rotate. The driving wheel drives the two driven wheels to rotate through the transmission belt. The driven wheels drive the mixing paddles to rotate through the rotating shaft and stir the manganese carbonate slurry, cooperating with the guiding and conveying effect of the spiral blade on the manganese carbonate slurry, improving the fluidity of the manganese carbonate slurry in the material supporting assembly, enabling the manganese carbonate slurry to fully contact the flue gas. Since bubbles will be generated in the manganese carbonate slurry during the ventilation of the air guide pipe, the bubbles can rise from the diversion holes on the material supporting frame after bursting. The pump body works to extract the manganese carbonate slurry from the material supporting frame through the feed pipe. The manganese carbonate slurry falls on the material supporting frame through the discharge pipe and can contact the rising gas again. Therefore, the adsorption effect of the manganese carbonate slurry is improved through a multi-stage absorption method, enabling the adsorption capacity of manganese carbonate to be fully exerted, which is beneficial to the subsequent efficient preparation work of high-purity manganese sulfate.

[0017] 2. In the present invention, a motor is used to drive the connecting shaft to rotate, and the connecting shaft drives the spiral blade to rotate. After passing through the feed valve pipe, the manganese carbonate ore powder can be sent into the inside of the material supporting frame by the spiral blade, achieving the purpose of automatic and uniform feeding, improving the operation convenience. Since a number of diversion holes are provided at the top of the material supporting frame, it can divert the gas and the manganese carbonate slurry falling from the discharge pipe, increasing the contact area between the gas and the manganese carbonate slurry, further improving the adsorption effect on sulfur dioxide. During the absorption process, manganese carbonate reacts with sulfur dioxide to obtain manganese sulfate. Since the bottom of the inner wall of the material supporting frame is designed as an arc surface, the manganese carbonate slurry in the material supporting frame can be concentrated towards the middle, facilitating the spiral blade to convey the material and preventing the material from remaining in the desulfurization tower and being difficult to remove. After opening the discharge valve pipe, the spiral blade can continuously work to automatically introduce the obtained manganese sulfate into the manganese sulfate purification equipment for purification, without transferring the manganese sulfate in the desulfurization tower, preventing the volatilization of irritating gases caused by the contact of manganese sulfate with the outside world, and improving the operation safety and convenience.

Because a plurality of diversion holes 502 are opened at the top of the material supporting frame 501, the gas and the manganese carbonate slurry falling from the discharge pipe 102 can be diverted, increasing the contact area between the gas and the manganese carbonate slurry and further improving the adsorption effect of sulfur dioxide.

[0027] The bottom of the inner wall of the material supporting frame 501 is designed as an arc surface, and the end of the air guiding assembly 6 penetrates through the top of the material supporting frame 501 and extends to the lower part inside the material supporting frame 501. Because the bottom of the inner wall of the material supporting frame 501 is designed as an arc surface, the manganese carbonate slurry in the material supporting frame 501 can be concentrated towards the middle, facilitating the spiral blade 805 to convey the material and preventing the material from remaining in the desulfurization tower 1 and being difficult to remove.

[0030] Below the inside of the material supporting component 5, there is a connecting shaft 804 installed between two fixed cylinders 801. A spiral blade 805 is fixedly connected to the outside of the connecting shaft 804. One end of the connecting shaft 804 penetrates through the fixed cylinder 801 and is fixed to the output shaft of the driving component 9. Due to the presence of the spiral blade 805, the rotation of the spiral blade 805 can automatically convey the material, and at the same time improve the fluidity of the manganese carbonate slurry in the material supporting frame 501.

[0031] One end of the material guiding component 8 is fixedly connected to a driving component 9. The driving component 9 is fixed outside the desulfurization tower 1. The two ends of the driving component 9 penetrate through the desulfurization tower 1 and are located above the material guiding component 8. The driving component 9 includes a motor 901.

[0032] An extraction component 10 is installed on the back of the desulfurization tower 1. One end of the extraction component 10 is clamped outside the material supporting component 5.

The other end of the feed pipe 103 is clamped below one side of the material supporting component 5. When the pump body 101 works, the feed pipe 103 extracts the manganese carbonate slurry from the material supporting frame 501.

[0034] The working principle of the present invention is:

[0035] The manganese carbonate ore powder with a particle size of 150 - 200 meshes is placed into the fixed cylinder 801 through the feed valve pipe 802. When the motor 901 operates, it can drive the connecting shaft 804 and the spiral blade 805 to rotate. During the rotation of the spiral blade 805, the manganese carbonate ore powder is sent into the material supporting frame 501. The spray pipe 7 is connected to a water source to supply water into the desulfurization tower 1, so that the water contacts the manganese carbonate ore powder in the desulfurization tower 1 and is mixed through the driving assembly 9 to form a manganese carbonate slurry. The proportion of manganese carbonate ore powder in the manganese carbonate slurry is 10%. The manganese carbonate slurry submerges the end of the air guide pipe 601. Secondly, the flue gas containing sulfur dioxide is introduced into the air cavity 4 through the intake pipe 3, and the flue gas is introduced into the manganese carbonate slurry in the material supporting assembly 5 through the air guide pipe 601, so that the manganese carbonate slurry can contact the flue gas containing sulfur dioxide and absorb sulfur dioxide. The motor 901 drives the driving wheel 903 to rotate. The driving wheel 903 drives two driven wheels 905 to rotate through the transmission belt 904. The driven wheels 905 drive the mixing paddle 907 to rotate through the rotating shaft 906 and stir the manganese carbonate slurry. Cooperating with the guiding and conveying effect of the spiral blade 805 on the manganese carbonate slurry, the fluidity of the manganese carbonate slurry in the material supporting assembly 5 is improved, so that the manganese carbonate slurry can fully contact the flue gas. Since bubbles will be generated in the manganese carbonate slurry during the ventilation process of the air guide pipe 601, after the bubbles burst, they can rise from the shunt holes 502 on the material supporting frame 501. The pump body 101 operates to extract the manganese carbonate slurry from the material supporting frame 501 through the feed pipe 103. The manganese carbonate slurry falls on the material supporting frame 501 through the discharge pipe 102 and can contact the rising gas again. The shunt holes 502 opened at the top of the material supporting frame 501 can shunt the gas and the manganese carbonate slurry falling from the discharge pipe 102, increasing the contact area between the gas and the manganese carbonate slurry and improving the adsorption effect on sulfur dioxide. During the absorption process, manganese carbonate reacts with sulfur dioxide to obtain manganese sulfate. After opening the discharge valve pipe 803, the spiral blade 805 continues to work and can automatically introduce the obtained manganese sulfate into the manganese sulfate purification device 11 for purification. The manganese sulfate purification device 11 purifies manganese sulfate by means of high-temperature crystallization purification, and uses the difference in solubility between manganese sulfate and impurity ion sulfates at a higher temperature for purification. Under the conditions of a crystallization temperature of 180 °C and a heat preservation time of 8 hours, manganese sulfate can be obtained as battery-grade high-purity manganese sulfate after three times of crystallization purification.
