Description

Technical Field

[0001] This utility model relates to the technical field of stirred reaction vessels for highly corrosive materials, and specifically to a stirred reaction vessel for highly corrosive materials. Background Technology

[0002] In reactors processing highly corrosive materials, gas dispersion is a critical technical issue. Due to the nature of these materials, the internal environment of the reactor is extremely harsh, placing high demands on the materials and structural design of the gas pipelines. Currently, the common practice in China is to connect a metal gas pipeline from the top of the reactor, extending along the reactor wall to the bottom, with aeration holes on the pipeline to allow the gas to rise and achieve initial mixing with the material. However, this structure results in poor gas dispersion. Furthermore, in reactors with agitators, while the agitator provides mixing, its movement can also cause the gas pipeline to shake. This shaking can not only cause sealing problems at pipeline connections but also accelerate corrosion and wear of the pipeline materials. Additionally, since the pipeline enters the reactor from the top, maintenance personnel need to enter the reactor to perform disassembly and maintenance work.

[0003] Patent document CN218774764U discloses a gas dispersion mechanism, including an air inlet pipe, a gas main pipe, and an aeration pipe; the gas main pipe is an annular pipe, the upper end of the aeration pipe is connected to the gas main pipe, the lower end is sealed, and aeration holes are provided on the pipe body and the sealed end face; the gas dispersion mechanism creates a gas pressurization state by changing the diameter of the pipe opening, so that the gas is output evenly and stably from the aeration holes, forming a jet-like airflow.

[0004] The aforementioned structure has the problem of not being able to work in highly corrosive stirred reactors, and for large reactors, the pipelines enter the reactor from above, which is not conducive to maintenance by the staff. Utility Model Content

[0005] The purpose of this invention is to provide a solution to the problems of rapid and uniform dispersion of gas in highly corrosive materials and safe operation by personnel.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a stirring reactor for highly corrosive materials, comprising a reactor and a gas dispersion mechanism, wherein the bottom of the reactor is provided with a bottom flange, the gas dispersion mechanism includes a first flange and an aeration head, the first flange and the bottom flange of the reactor are connected by bolts, the aeration head is provided with a pagoda connector, the pagoda connector is connected to a gas pipe, and a stirring device is provided inside the reactor.

[0007] The principle and beneficial effects of this invention are as follows: the mounting base is installed at the bottom of the reactor, and the aeration sand head extends into the reactor from the bottom, allowing gas to enter the reactor from the bottom. The aeration sand head improves gas dispersion, and the gas entering from the bottom allows for better contact with the liquid, resulting in a more complete reaction.

[0008] Option 2, a preferred embodiment of the basic option, involves a gas pipe connector chuck connected to the first flange. This chuck is connected to a transition chuck via a clamp. The chuck contains a gas pipe connector, and the transition chuck is connected to a manual ball valve via a clamp. This manual ball valve is connected to another gas pipe connector chuck. The gas pipe connector allows for quick disassembly and installation of the gas pipe. Before the reactor stops operating, the manual ball valve is closed to prevent liquid backflow into the gas pipe. Maintenance and replacement can be performed externally to the reactor, ensuring the safety of personnel.

[0009] Option 3, a preferred option of the basic option, has a discharge port on the first flange, and a second flange on the discharge port. The first flange is installed at the original discharge port position of the reactor, and a discharge port is provided on the first flange to replace the original discharge port. The second flange is permanently connected to the subsequent process equipment.

[0010] Option 4, an optimal choice from the basic option, features a threaded tube on the mounting base, a mounting disc on the threaded tube, and a chuck bolted to the mounting disc. The aeration sand head is installed between the mounting disc and the chuck. The threaded tube elevates the installation position of the aeration sand head, ensuring it does not obstruct the discharge port.

[0011] Option 5, the preferred option of the basic solution, involves securing the trachea to the threaded tube with cable ties. When pressurized gas is introduced into the trachea, it will vibrate, reducing its lifespan. Securing the trachea to the threaded tube with cable ties prevents this vibration.

[0012] Option 6, an optimized version of Option 5, uses Teflon for the first flange, reactor bottom flange, pagoda connector, gas pipe, gas pipe connector chuck, transition chuck, gas pipe connector, second flange, chuck, and cable ties. Teflon is resistant to acidic corrosion, so all parts of the reactor that come into contact with materials are made of Teflon or coated with a Teflon coating to extend their service life.

The gas dispersion mechanism 2 is provided with a first flange 4, which is connected to the bottom flange 5 of the reactor. The gas dispersion mechanism 2 includes an aeration sand head 3 with a pagoda connector 6, which is connected to a gas pipe 7. A mechanical stirring device 19 is provided inside the reactor 1. The first flange 4 is connected to a gas pipe connector chuck 8. The gas pipe connector chuck 8 is connected to a transition chuck 9 through a clamp 11. The system includes an air pipe connector 10. A transition chuck 9 is connected to a manual ball valve 12 via a clamp 11. The manual ball valve 12 is connected to another air pipe connector chuck 8. A first flange 4 has a discharge port 13, and the discharge port 13 has a second flange 14. The first flange 4 has a threaded pipe 15, and the threaded pipe 15 has a mounting plate 16. The mounting plate 16 is bolted to a chuck 17. An aeration sand head 3 is installed between the mounting plate 16 and the chuck 17. The air pipe 7 is fixed to the threaded pipe 15 via a cable tie 18. The first flange 4, the reactor bottom flange 5, the pagoda connector 6, the air pipe 7, the air pipe connector chuck 8, the transition chuck 9, the air pipe connector 10, the second flange 14, the chuck 17, and the cable tie 18 are all made of Teflon.

[0021] The implementation method of this embodiment is as follows: First, place the aeration sand head 3 on the mounting plate 16, press the aeration sand head 3 with the chuck 17, and tighten the chuck 17 and the mounting plate 16 with bolts. The chuck 17 is annular to facilitate the dispersion of gas into the reactor. Then, connect the transition chuck 9, the air pipe connector chuck 8, and the manual ball valve 12 with clamps to form a quick-connect coupling. Insert one end of the air pipe 7 into the air pipe connector 10 at one end of the quick-connect coupling, connect the other end of the air pipe 7 to the pagoda connector 6, and secure it with cable ties. Fix the air pipe to the threaded pipe 15 with cable ties 18. Connect the quick-connect coupling to the first flange 4, and connect the first flange 4 to the bottom flange 5 of the reactor with bolts.

[0022] After installation, first perform a full water leak test on the reactor to check for leaks in the gas dispersion mechanism and manual ball valve 12. Then open the gas storage tank valve and open the manual ball valve 12 of the gas dispersion mechanism. Observe the aeration sand head 3 at the bottom of the reactor through the manhole. When the gas dispersion mechanism is running normally, turn on the reactor stirring device to observe the gas-liquid reaction. When the overall test run is normal, open the discharge port to discharge the internal test liquid. Before stopping the reactor, close the manual ball valve 12 to prevent the material in the reactor from flowing back into the pipeline.
