Technical Field

[0001] This utility model relates to the field of potassium fluorotitanate production and processing technology, and in particular to a potassium fluorotitanate production and preparation device. Background Technology

[0002] Compared with high-temperature fluorination catalysts, low-temperature fluorination catalysts have higher catalytic activity at low temperature and low pressure. They are particularly suitable for fluorination reactions where the raw material or reaction product is olefin and the target product is prone to dehydrohalogenation at high temperature. They also have the characteristics of long service life and low energy consumption. Although low-temperature fluorination catalysts have many advantages, they still have some shortcomings.

[0003] In the production of potassium fluorotitanate, the high temperature inside the reactor causes hydrofluoric acid to easily volatilize. This not only leads to waste of raw materials but also poses serious risks to the environment and the health of operators. Therefore, it is particularly important to develop a potassium fluorotitanate production process that can reduce hydrofluoric acid volatilization, improve raw material utilization, and protect the environment and the health of operators.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please see Figure 1As shown in one embodiment of this utility model, a potassium fluorotitanate production and preparation device includes a reaction vessel 1, a support component 2 located at the bottom of the reaction vessel 1, the support component 2 providing support for the installation of the reaction vessel 1, the cooling component 4, and the recovery component 5, a stirring component 3 located on the reaction vessel 1, which can effectively stir and mix the potassium fluorotitanate on the inner wall of the reaction vessel 1, thereby accelerating the production efficiency of potassium fluorotitanate, a cooling component 4 located at the top of the reaction vessel 1 and cooperating with the support component 2, and a recovery component 5 at the bottom of the cooling component 4. The cooperation between the cooling component 4 and the recovery component 5 forms a hydrofluoric acid vapor recovery and condensation device. Through the condenser 44 and the transfer pump 53 and other equipment, the volatilized hydrofluoric acid vapor is condensed, recovered, and transported into the reaction vessel 1, realizing the recycling of hydrofluoric acid, reducing volatilization loss, and improving the utilization rate of raw materials.

[0019] Please see Figure 3 As shown, in one embodiment of this utility model, the cooling assembly 4 includes a steam pipe 41 disposed at the top of the reactor 1. The steam pipe 41 is inserted into the reactor 1. The steam pipe 41 effectively transports the steam generated during the stirring of potassium fluorotitanate to the first conveying pipe 42. The reactor 1 is provided with the first conveying pipe 42 at one end. The first conveying pipe 42 facilitates the connection between the steam pipe 41 and the cooling pipe 43. The cooling pipe 43 is disposed at one end of the first conveying pipe 24, and a condenser 4 is disposed on one side of the cooling pipe 43. 4. Through the cooperation between the cooling pipe 43 and the condenser 44, the generated hydrofluoric acid vapor is effectively replaced into a cooled liquid. A tail gas recovery tower 45 is provided on one side of the condenser 44. With the tail gas recovery tower 45, when a small amount of uncondensed hydrofluoric acid vapor is still discharged from the outlet of the condenser 44 after the condenser 44 has processed it, the tail gas absorption tower 45 is filled with an alkaline absorbent (such as sodium hydroxide solution), which can further absorb the residual hydrofluoric acid vapor, ensuring that the tail gas meets the emission standards and protecting the environment and the health of the operators.

[0020] Please see Figure 4As shown in one embodiment of this utility model, the recycling component 5 includes a second conveying pipe 51 disposed at the bottom of the cooling pipe 43. The second conveying pipe 51 effectively transports the cooled liquid to the recycling tank 52. The recycling tank 52 is disposed at one end of the second conveying pipe 51. A liquid level sensor is installed on the recycling tank 52. When the liquid level reaches a certain height, the conveying pump 53 can be started for transportation. The conveying pump 53 is disposed on one side of the recycling tank 52. The conveying pump 53 is bolted to a third conveying pipe 54. A fixing seat 55 is disposed on the third conveying pipe 54. A water inlet pipe 56 is disposed on one side of the third conveying pipe 54. The water inlet pipe 56 extends into the reactor 1. Through the cooperation between the conveying pump 51, the third conveying pipe 54 and the water inlet pipe 56, the conveying pump 53 can be started to transport the recycled hydrofluoric acid liquid back to the reactor 1 after the liquid in the recycling tank 52 reaches a certain height, thereby realizing recycling.

[0021] Please see Figure 1 As shown in one embodiment of the present invention, the support assembly 2 includes a support column 21 disposed at the bottom of the reactor 1. The support column 21 increases the height of the reactor 1, preventing the reactor 1 from directly contacting the ground and also preventing the reactor from contacting personnel on the ground, thereby increasing the safety of the reactor during high-temperature reactions. A placement plate 22 is disposed at the bottom of the support column 21, and support seats 23 are disposed around the bottom of the placement plate 22. The cooperation between the placement plate 22 and the support seats 23 facilitates the installation of the reactor 1 and the recovery assembly 5. A fixing frame 24 is disposed at the top of the placement plate 22, which effectively fixes the cooling assembly 4.

[0022] Please continue reading. Figure 3 As shown, in one embodiment of the present invention, a connecting rod 241 is welded to the bottom of the fixing frame 24, and a fixing ring 242 is bolted to the bottom of the connecting rod 241. A first conveying pipe 42 is movably sleeved inside the fixing ring 242. Through the cooperation between the connecting rod 241 and the fixing ring 242, the first conveying pipe 42 can be movably installed on the fixing frame 24, thereby fixing the first conveying pipe 42 and facilitating the installation of the cooling pipe 43 and the condenser 44.

[0023] Please see Figure 2As shown in one embodiment of the present invention, the stirring assembly 3 includes a drive motor 31 disposed on the top of the reaction vessel 1. The drive motor 31 provides power for the rotation of the rotating rod 32. The bottom of the drive motor 31 is connected to the rotating rod 32 via an output shaft. A sleeve 33 is fixedly connected to the bottom of the rotating rod 32. The cooperation between the rotating rod 32 and the sleeve 33 facilitates the installation of the water inlet pipe 34. A water inlet channel 34 is provided between the sleeve 33 and the rotating rod 32. The heat-sealed water inlet pipe 34 facilitates better entry of liquid into the nozzle 35. A water inlet pipe 37 is provided at the top of the water inlet channel 34, which provides liquid supply for the production of potassium fluorotitanate.

[0024] Please continue reading. Figure 2 As shown in one embodiment of the present invention, the stirring assembly 3 further includes a nozzle 35 and a stirring rod 36. The nozzle 35 penetrates the sleeve 33 and enters the water inlet pipe 34. By setting the nozzle 35, the accelerated liquid can be effectively added to various positions in the reactor 1, so that the potassium fluorotitanate in the reactor 1 can be fully reacted. The stirring rod 36 is staggered on the sleeve 33. By setting the stirring rod 36, the potassium fluorotitanate inside the reactor 1 can be fully stirred, so that the potassium fluorotitanate can react more fully.

[0025] In operation, the drive motor 31 is first started, which drives the rotating rod 32 to rotate. Under the drive of the rotating rod 32, the sleeve 33 rotates synchronously, thereby driving the stirring rod 36 on the sleeve 33 to rotate. This effectively stirs and mixes the potassium fluorotitanate on the inner wall of the reactor 1, thus accelerating the production efficiency of potassium fluorotitanate. Secondly, the steam generated during the stirring of potassium fluorotitanate is transported through the steam pipe 41 to the first conveying pipe 42 and then to the cooling pipe 43. Next, the recovered steam is cooled into liquid by the condenser 44 and then transported through the second conveying pipe 5. 1. The mixture is transported to the recovery tank 52. Meanwhile, after the condenser 44 has processed the mixture, a small amount of uncondensed hydrofluoric acid vapor will still be discharged from the outlet of the condenser 44. This vapor is then passed through the tail gas absorption tower 45, which is filled with an alkaline absorbent (such as sodium hydroxide solution). This absorbent further absorbs the residual hydrofluoric acid vapor, ensuring that the tail gas meets emission standards and protecting the environment and the health of the operators. The recovered liquid is then pumped to the third conveying pipe 54 by the transfer pump 53, and finally transported to the reactor 1 through the water inlet pipe 56. This process achieves recycling, reduces volatilization loss, and improves the utilization rate of raw materials.

[0026] The drive motor, delivery pump, and condenser in this invention are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.
