Description

Technical Field

[0001] This invention relates to the field of suspension roasting technology, and in particular to a suspension roasting phase change reactor with controllable mineral powder flow direction. Background Technology

[0002] For complex and difficult-to-process iron ores, traditional beneficiation technologies are unable to achieve ideal technical indicators, and suspension roasting technology has gradually become one of the important processing methods for complex and difficult-to-process iron ores.

[0003] Phase change reactors are a crucial component of suspension roasting equipment. Currently, most industrially used phase change reactors have a square structure, consisting of a loosening chamber and a fluidizing chamber. Mineral powder enters from the top of the loosening chamber, where it achieves initial fluidization under the action of loosening air. Under pressure differential, the fluidized material flows into the fluidizing chamber, completing the phase change process and exiting the reactor through the discharge port. During this process, the material flow is significantly affected by the pressure differential, leading to high gas consumption and unstable discharge during equipment operation.

[0004] Therefore, the prior art discloses a gas suspension roasting furnace with a fluidization residence device, application number 202223290502.1, and authorization announcement number CN 219199985. According to the authorization announcement date of U, June 16, 2023, the principle of the roasting furnace is as follows: After the material enters the cylinder, it is fed into a fluidized bed device, where gas mixes with the material and boils until it overflows from the outlet. The fluidized bed device includes an air distribution plate, on one side of which multiple air distribution pipes are evenly distributed. The upper end of each air distribution pipe is fitted with an air cap and connected to it. Therefore, although the existing technology controls the flow direction of the material through the fluidized bed device, which solves the above problem, the following problems still exist: the residence time of the material in the cylinder is not long, and it overflows directly from the outlet at the top after boiling, resulting in incomplete material reaction. In order to ensure that the material reacts fully, it is necessary to increase the height of the cylinder and prolong the time for the fluidized material to overflow from the outlet. However, this design results in a larger volume of the roasting furnace, and the reaction time is still insufficient for complex and difficult-to-select iron ore materials. Summary of the Invention

[0005] The purpose of this invention is to provide a suspension roasting phase change reactor that ensures the complete reaction of materials and allows for controllable flow of mineral powder.

[0006] To achieve the above-mentioned objectives, the suspension roasting phase change reactor with controllable mineral powder flow of the present invention employs the following technical solution:

[0007] A suspension roasting phase change reactor with controllable mineral powder flow includes a reactor shell with a feed port and a discharge port. The reactor shell contains a reaction chamber, and the outer wall of the reactor shell is provided with an insulation layer and a heating layer. The reaction chamber has a meandering flow channel, including a first material rising channel, a material settling channel, and a second material rising channel arranged along the left-right direction of the reaction chamber. The bottom of the reactor shell has an air distribution plate with an air cap assembly. The air cap assembly includes a first air cap and a second air cap, with the first air cap located at the first and second material rising channels, and the second air cap located at the bottom of the material settling channel. The air distribution plate has air distribution outlets, and air supply devices are installed at the air distribution outlets. The air supply pipe has an air supply hole at its upper end; the second air cap includes a second air cover rotatably mounted on the air supply pipe, the second air cover and the air supply pipe are rotatably connected by a bearing, the second air cover has a second air chamber inside, and the upper end of the air supply pipe extends into the second air chamber of the second air cover; the side wall of the second air cover has a rotating air port, the air distribution plate has a deflector plate on the outer periphery of the second air cover, the deflector plate and the outside of the second air cover have a rotation gap, the deflector plate is evenly distributed along the circumferential spacing of the second air cover, the multiple deflector plates are all arranged in a clockwise or counterclockwise direction, the inclined deflector plate is directly opposite the rotating air port; the side wall of the second air cover above the rotating air port has a material blowing air port, the upper end of the deflector plate is lower than the material blowing air port.

[0008] Preferably, the first material rising channel is connected to the feed port, the second material rising channel is connected to the discharge port, and the material settling channel is located between the first material rising channel and the second material rising channel; the flow channel is formed by a partition component, the partition component including a first partition plate and a second partition plate arranged vertically inside the reactor shell, the first partition plate and the inner wall of the reactor shell forming a first material rising channel, the first partition plate and the second partition plate forming a material settling channel, and the second partition plate and the inner wall of the reactor shell forming a second material rising channel; the lower end of the first partition plate contacts the air distribution plate, and the upper end of the first partition plate leaves a first gap with the top wall of the reactor shell; the upper end of the second partition plate leaves a second upper gap with the top wall of the reactor shell, and the lower end of the second partition plate leaves a second lower gap with the air distribution plate, the second lower gap being close to the side of the second air cap, and the upper end of the second partition plate being higher than the upper end of the first partition plate. This invention divides the flow channel into a first material rising channel, a material settling channel, and a second material rising channel by setting a first partition plate and a second partition plate, thereby enabling the material to flow up and down in a meandering manner, extending the residence time of the material in the reaction chamber, making the contact between the material and the reducing gas more sufficient, and ensuring that the material reaction is complete.

[0009] Preferably, a guide plate is provided above the first partition plate and the second hood. The guide plate is inclinedly arranged on the first partition plate, with its upper inclined end fixed to the first partition plate and its lower inclined end close to the right side of the second hood. The left side of the second hood is located below the guide plate, and a flow gap is left between the lower inclined end of the guide plate and the second partition plate. By setting the guide plate, after the material descends in the material settling channel, it is guided by the guide plate to fall on the right side of the second hood, thereby facilitating the lateral blowing of the material by the second hood and achieving a lateral feeding effect.

[0010] Preferably, the second hood is provided with a baffle plate inside, which is arranged between the blowing air port and the rotating air port, and the baffle plate is provided with an opening to facilitate airflow.

[0011] Preferably, the first wind cap includes a first wind cover fixedly mounted on the air distribution plate, the first wind cover has a first air chamber inside, the upper end of the air supply pipe extends into the first air chamber of the first wind cover, and the first wind cover has an air outlet located at the lower end of the first air chamber.

[0012] Preferably, the outer wall of the insulation layer is provided with an outer shell, the heating layer is disposed inside the insulation layer and is disposed close to the outer wall of the reactor shell, and a temperature sensor is provided in the reaction chamber. By setting the temperature sensor, the temperature in the reaction chamber is detected. When the temperature is low, the heating layer is controlled to heat, and when the temperature is reached, the heating layer automatically stops heating.

[0013] Preferably, the feed port is located at the lower end of one side of the reactor shell, and a feed pipe is provided at the feed port. The feed pipe is connected to a storage pipe via a discharge conduit. The storage pipe is vertically installed within the insulation layer. The storage pipe has a discharge port at the upper end of the reactor shell, and the lower end of the storage pipe is connected to the discharge conduit, which is inclined. The inner port of the feed pipe is connected to the reaction chamber, and the outer port of the feed pipe is provided with a high-pressure jet nozzle, which is connected to a high-pressure gas supply device. The discharge port is located at the upper middle end of the other side of the reactor shell, and a discharge pipe is provided at the discharge port, extending through the outer shell. The discharge pipe is inclined, with its upper inclined end on the reactor shell and its lower inclined end on the outer shell. By setting up a high-pressure jet, the material is fed by blowing, resulting in uniform material feeding without clogging the feed port. Simultaneously, the inclined arrangement of the discharge pipe facilitates material discharge.

[0014] Preferably, the upper end of the air supply pipe passes through the air distribution port of the air distribution plate, and the lower end of the air supply pipe is connected to the air chamber through a flexible hose. The air chamber is connected to a high-pressure air supply device, and a rotor flow meter is installed on the flexible hose.

[0015] Preferably, the air distribution plate is detachably installed at the bottom of the reactor shell, and a groove is provided at the position where the air distribution plate contacts the first partition plate. The groove is adapted to the first partition plate, and the lower end of the first partition plate is inserted into the groove. The present invention provides a detachable air distribution plate, thereby facilitating the inspection and maintenance of the inside of the reactor shell; at the same time, the cooperation between the groove and the first partition plate ensures the upward and downward circulation of materials.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention extends the residence time of materials in the reaction chamber by setting up a meandering flow channel in the upper and lower parts of the reaction chamber, so as to make the contact between the materials and the reducing gas more sufficient and ensure the complete reaction of the materials.

[0018] 2. This invention incorporates a second air hood in the material settling channel. When gas from the air supply pipe hits the baffle plate, it generates a reverse force on the second air hood, causing it to rotate. As the second air hood rotates, the high-pressure gas inside the second air hood is blown out through the blowing port. When the blowing port is directly facing the material, the material is blown into the second material rising channel on the right. At this time, the blowing port produces a lateral blowing effect on the material. When the blowing port rotates and deviates from the material, it stops blowing the material, causing it to settle. This process repeats, achieving a better feeding effect. Attached Figure Description

[0028] The specific working process and principle of this invention: The high-pressure gas supply device 33 operates, sending the high-pressure gas from the gas chamber into the gas supply pipe 28 through the hose 15. Then, the gas enters the first air cap 12 and the second air cap 14 through the gas supply pipe 28. At the same time, the material enters the storage pipe 2 from the discharge port 201, and then slowly enters the feeding pipe 10 through the discharge guide 8. The material in the feeding pipe 10 is blown into the reaction chamber by the high-pressure jet nozzle 9. At this time, under the action of the first partition plate 3 and the second partition plate 20, the material first enters the first material rising channel 5. Under the action of the first air cap 12, the reducing gas sent in by the gas supply pipe 28 is discharged from the air outlet 12c of the first air hood 12a, blowing the material. At this time, the material is suspended and flows upward under the blowing until the material reaches the first gap 25. Then, it flows from the first gap 25 to the material settling channel 19, where the material settles. Under the action of gravity, the material falls to the guide plate 26. Under the inclination of the guide plate 26, the material will gather in the second... With a lower spacing of 18, and the material piled on the right side of the second hood 14a, the reducing gas from the gas supply pipe 28 blows onto the baffle plate 30, causing the second hood 14a to generate a reverse force and rotate. When the second hood 14a rotates, the high-pressure gas inside the second hood 14 is blown out through the material blowing port 14b. When the material blowing port 14b is directly facing the material, the material is blown into the second material rising channel 21 on the right. At this time, the material blowing port 14b produces a lateral blowing effect on the material. When the material blowing port 14b rotates and deviates from the material, it will not blow the material, and the material will settle. This process repeats to achieve a better feeding effect. When the material enters the second material rising channel 21, it continues to float and flow upward under the action of the first hood 12 until it is discharged from the outlet 23. This invention realizes the up-and-down meandering flow of the material in the reaction chamber to increase the contact between the material and the reducing gas, making the contact more sufficient and the material reaction complete.
