Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of titanium metallurgy equipment, in particular to a sponge titanium reduction reactor. BACKGROUND

[0002] Sponge titanium, as an important primary product of titanium metal, has excellent characteristics such as low density, high specific strength, corrosion resistance, and good biocompatibility. Due to its superior performance, sponge titanium has broad application prospects in aerospace, chemical industry, biomedicine, and other fields.

[0003] In the production technology of sponge titanium, the magnesium hot reduction method is widely used due to its advantages such as high purity of produced sponge titanium, low reaction temperature, simple process, and environmental friendliness. In the magnesium hot reduction method, titanium tetrachloride reacts with magnesium to gradually form sponge titanium. The reaction is carried out in a reduction reactor, usually under inert atmosphere with temperature controlled at 800-1000°C to promote the full contact and reaction of titanium tetrachloride vapor with molten magnesium, generating sponge titanium and magnesium chloride byproduct. This porous structure has high porosity and large specific surface area, facilitating efficient removal of impurities in subsequent leaching, distillation, and other processes, ensuring the purity and uniformity of sponge titanium. However, in the continuous production process, as the amount of sponge titanium generated gradually increases, the weight of the sponge titanium column formed gradually increases, resulting in reduced porosity, specific surface area, and densification of the bottom sponge titanium under the action of pressure and high temperature, thereby affecting subsequent impurity removal processes such as leaching and distillation.

[0004] In related technology, in order to delay the degree of sponge titanium extrusion densification, a sponge titanium production equipment with publication number CN115094248B is disclosed, which provides bearing support to the sponge titanium column through the annular support connecting piece, reducing the extrusion effect of the self-weight of the sponge titanium column on the bottom of the sponge titanium column. Also, a magnesium hot reduction sponge titanium production process and equipment with publication number CN118773455B is disclosed, which supports the generated sponge titanium body through the setting of a circular truncated cone reactor body. Both of them have the function of supporting sponge titanium to prevent densification of the bottom of the sponge titanium block in a high temperature environment. However, when supporting the sponge titanium column, both of them use edge support, and the sponge titanium column is an integral structure, so the gravity dispersion degree is low, which still leads to densification of the bottom of the sponge titanium column.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0022] As shown in Figures 1 to 7 , the sponge titanium reduction reactor of the present application comprises a heating furnace 1 and a reactor main body 11 arranged in the heating furnace 1; It also comprises a lowering and separating mechanism arranged inside the reactor main body 11, which realizes the separation of sponge titanium products by gradually lowering the liquid level height in the reactor main body 11; The lowering and separating mechanism comprises a liquid discharge pipe 12, a gas discharge pipe 13, a filter screen plate 14 and a liquid level sensor; The inner cavity diameter of the reactor main body 11 gradually decreases from top to bottom, and the reactor main body 11 is filled with magnesium chloride liquid in the initial state, and is divided into a gas phase zone 25, a liquid phase zone 27 and a reaction zone 26 between them; The liquid discharge pipe 12 and the gas discharge pipe 13 are respectively fixedly installed at the bottom end and the top end of the reactor main body 11, the liquid discharge pipe 12 is used for periodically discharging magnesium chloride liquid, and the gas discharge pipe 13 is connected with a condensing device 6; The filter screen plate 14 is fixedly installed inside the reactor main body 11, and the filter screen plate 14 is located above the liquid discharge pipe 12; The liquid level sensor is installed inside the reactor body 11, which is used to detect the liquid level inside the reactor body 11 in real time, matches the liquid discharge pipe 12, controls the periodic equal interval drop of the reaction zone 26, and the drop height of the reaction zone 26 is greater than the height of the generated single titanium sponge column.

[0023] The liquid level sensor includes a float 2, an extension rod 21 and a detection tube 22. The liquid level sensor is installed at the top end of the reactor, wherein the detection tube 22 is fixedly installed at the top end of the reactor, the extension rod 21 is installed in the detection tube 22 in a lifting manner, the bottom end of the extension rod 21 penetrates and extends into the liquid level sensor, the float 2 is installed at the bottom end of the extension rod 21, the density of the float 2 is less than the density of the magnesium liquid, and the detection tube 22 identifies the liquid level in the reactor by detecting the displacement of the extension rod 21.

[0024] In the preparation process of titanium sponge by magnesium hot reduction method, the gasified titanium tetrachloride gradually reacts with the magnesium liquid to generate titanium sponge, the reaction first occurs on the surface of the magnesium liquid in contact with the inner wall of the reactor body 11, and then gradually grows to the center of the reactor body 11, and then with the continuous reaction, the generated titanium sponge extends in a columnar shape, in this process, due to the gradually increasing weight of the continuously growing titanium sponge column, the texture of the titanium sponge at the bottom will gradually become compact under the action of heavy pressure, in order to improve this situation, in the present application, by setting the drop separation mechanism, in the process of continuous generation of titanium sponge, by controlling the periodic large drop of the liquid level in the reactor, matching the change of the inner diameter of the reactor body 11, in the reaction process, the generated titanium sponge forms multiple titanium sponge columns separated from each other in the vertical direction, thereby improving the degree of compaction at the bottom caused by the weight.

[0025] Specifically, in the magnesium hot reduction method, after the reactor body 11 is hoisted into the heating furnace 1, it is heated by the heating furnace 1, so that the magnesium liquid stored in the reactor body 11 is in a molten state, and in the initial stage, the reactor body 11 also stores magnesium chloride liquid, because the density of magnesium chloride is greater than that of magnesium liquid, so magnesium chloride and magnesium liquid are in a layered state, in the present application, the magnesium liquid surface is at a pre-designed height in the initial state, at this time the float 2 floats on the surface of the magnesium liquid, as the equipment is opened one by one, at this time titanium tetrachloride is gradually added to the reactor, titanium tetrachloride is vaporized before falling onto the surface of the magnesium liquid, and the vaporized titanium tetrachloride reacts with the magnesium liquid to generate titanium sponge, and in this process, a large amount of heat is released, as the reaction continues, the magnesium liquid is gradually consumed, so that the titanium sponge grows gradually from the inner wall of the reactor body 11 to the center, and then grows along the vertical direction to form a columnar structure, because the inner cavity diameter of the reactor body 11 decreases step by step from top to bottom, so the generated titanium sponge column is supported by the inclined surface of the inner wall of the reactor body 11, and the pressure on the titanium sponge below is reduced, but as the height of the titanium sponge column continues to increase, its gravity gradually increases, combined with high temperature hot melting, which will cause the titanium sponge column to have a compression downward trend, and as the height of the titanium sponge column continues to increase, the trend will be strengthened, so when the reaction continues to the preset period, the electromagnetic control valve installed at the outlet of the liquid discharge pipe 12 is opened under the control of the pre-set program, and the magnesium chloride liquid is discharged outward, as the magnesium chloride liquid continues to be discharged, the liquid level in the reactor body 11 continues to drop, thereby causing the float 2 and the extension rod 21 to drop, in the present application, a detection sensor is installed in the detection tube 22 for real-time detection of the position height of the top end of the extension rod 21, thereby judging the liquid level height in the reactor, when the liquid level height drops to the pre-set value, titanium tetrachloride is again introduced to generate titanium sponge, it should be noted that the cycle setting is related to the addition rate of titanium tetrachloride, after the addition rate of titanium tetrachloride is determined, the volume of the titanium sponge column generated in a cycle is certain, and the diameter of the titanium sponge generated at the initial position is calculated to determine the height of the titanium sponge column generated in a cycle, and then according to the height of the generated titanium sponge, the staff pre-sets the liquid level height after liquid discharge, so that the titanium sponge generated again is spaced a certain height from the titanium sponge column supported and suspended above the liquid level, and repeated operation can generate multiple titanium sponge columns arranged in the vertical direction in the reactor body 11, compared with the titanium sponge column as a whole in the related art, the present application divides the titanium sponge column into multiple parts, which reduces the weight of the single titanium sponge column, not only facilitates the subsequent removal of the titanium sponge column, but also relieves the compact state of the titanium sponge column caused by gravity compression, and at the same time, because the titanium sponge columns are in a separated state, compared with the titanium sponge column as a whole, the heat dissipation condition in the reaction process is also enhanced, so as to reduce the probability of sintering phenomenon caused by excessive local temperature.

[0026] The present application sets the lowering separation mechanism, in the process of titanium sponge generation, from top to bottom step by step control liquid surface to greatly reduce, cooperate with the diameter from top to bottom step by step decrease of reactor main body 11 to the support of titanium sponge column, in the whole reaction process, generate multiple titanium sponge column arranged in vertical direction, and then through the separation of titanium sponge column, the height of single titanium sponge column is reduced, and the weight is reduced, and then the compression of titanium sponge column in the generation process is effectively relieved, and the realization of image is realized, and the titanium sponge column is also convenient for later taking out, distillation and other operations.

[0027] As a preferred embodiment of the present application, the float 2 is a conical structure, and the float 2 conical structure opening faces the liquid phase zone 27, and the extension rod 21 is smaller than the maximum diameter of the float 2.

[0028] The extension rod 21 is a hollow tubular structure, the float 2 is a hollow structure, the inner cavity of the extension rod 21 is in communication with the inner cavity of the float 2, the side wall of the float 2 is provided with a jet hole 23, and the detection tube 22 is connected with the inert gas circulating device 4 and the titanium tetrachloride pumping device 5.

[0029] The float 2 is rotatably connected with the extension rod 21, the jet holes 23 are uniformly arranged along the circumferential direction of the float 2, and the jet holes 23 are all inclinedly arranged, and the inert gas flow is sprayed to drive the float 2 to rotate.

[0030] The extension rod 21 is made of high-thermal-resistance material, the heat-conducting member 24 is fixedly installed in the float 2, one end of the heat-conducting member 24 extends into the inner cavity of the extension rod 21, and the other end extends into the liquid phase zone 27.

[0031] One end of the heat-conducting member 24 located in the inner cavity of the extension rod 21 is designed in a spiral blade shape, the jet hole 23 is located above the bottom surface of the inner cavity of the float 2, and one end of the heat-conducting member 24 located in the liquid phase zone 27 is designed in a fan shape. The shape of the heat-conducting member 24 not only increases the contact area of the heat-conducting member 24 with titanium tetrachloride liquid, inert gas and hot magnesium liquid, enhances the heat conduction efficiency, but also pushes the titanium sponge particles generated on the liquid surface during the rotation of the float 2, and promotes the titanium sponge particles to move towards the inner wall of the reactor main body 11. At the same time, the height of the jet hole 23 can also make the unvaporized titanium tetrachloride liquid gather at the bottom of the float 2, continuously heat and vaporize, so as to reduce the liquid-liquid reaction of titanium tetrachloride and magnesium liquid, and reduce the generation probability of hard core in titanium sponge.

[0032] After the device is started, when the temperature inside the reactor body 11 reaches a pre-set value, the inert gas circulating device 4 and the titanium tetrachloride pumping device 5 are started, the titanium tetrachloride liquid is mixed in the inert gas and pumped into the detection tube 22, and then transported into the inner cavity of the float 2 through the inner cavity of the extension rod 21. In this process, since the gas-liquid mixture is in contact with the heat-conducting piece 24 extending into the inner cavity of the extension rod 21, the titanium tetrachloride gradually vaporizes, and finally the mixed gas stream is sprayed out of the spray hole 23. The gas stream is sprayed in parallel to the liquid surface, and since the spray hole 23 is inclined in the circumferential direction of the float 2, the float 2 rotates under the reaction force of the gas stream spraying, and then the inert gas is sprayed to make the titanium tetrachloride gas uniformly diffuse to the magnesium liquid surface. When the inert gas is sprayed, it can also impact the titanium tetrachloride particles generated on the liquid surface, so that the titanium sponge particles move towards the inner wall of the reactor body 11, and cooperate with the existence of the float 2, so that the central part of the generated titanium sponge column is in the form of a hole. The existence of the hole not only enhances the heat dissipation effect of the titanium sponge column, but also provides a path for the discharge of the inert gas. At the same time, since the gas stream flows upward from the liquid surface to the exhaust pipe 13 and is discharged into the condensing device 6, in this process, the gas stream flow path is opposite to the direction of gravity, which can also form a certain lifting force for the generated titanium sponge column. After the inert gas mixed with evaporated magnesium and unreacted titanium tetrachloride is condensed and separated in the condensing device 6, it is returned to the inert gas circulating device 4 again, so as to recycle the inert gas.

[0033] As a preferred embodiment of the present application, a supporting mechanism mounted on the extension rod 21 is further included, and the supporting mechanism includes a supporting rod 3 and a connecting ring 31. The bottom end of the extension rod 21 is designed in a T shape, a plurality of connecting rings 31 are slidably sleeved and mounted on the extension rod 21, and the connecting rings 31 are all located above the float 2. The supporting rod 3 is fixedly installed on the connecting ring 31, and a plurality of supporting rods 3 gradually decrease in length from top to bottom.

[0034] The middle part of the supporting rod 3 is designed in an arc shape, and the two ends of the supporting rod 3 extend below the float 2.

[0035] The supporting rod 3 is fixedly installed with a coaxially designed supporting ring 32, and the supporting ring 32 is used to increase the contact area of the supporting rod 3 with the titanium sponge column.

[0036] In order to further improve the support effect of the plurality of titanium sponge columns generated in the vertical direction, in the present application, the liquid surface and the float 2 are at the set initial height in the initial state, at this time, the longest support rod 3 is supported at the current height and does not descend with the float 2 due to the limitation of the diameter of the reactor body 11, and continues to generate titanium sponge columns as the inert gas and titanium tetrachloride continue to be pumped in, since the support rod 3 sleeved on the connecting ring 31 is below the liquid surface at this time, when the titanium sponge gradually generated on the liquid surface descends, it is intercepted by the support rod 3 and the support ring 32, when a time period is reached, the liquid surface drops significantly, at this time, the remaining connecting rings 31 and support rods 3 follow the liquid surface to descend, after reaching the preset liquid surface height, the support rod 3 arranged in the second place in length is limited by the diameter of the reactor body 11, and in multiple periods, the plurality of support rods 3 are gradually dispersed at different heights of the reactor body 11, cooperating with the support ring 32, to support the titanium sponge column, further reducing the probability of the titanium sponge column descending and accumulating.

[0037] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
