[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The feed hopper 6 is used for continuous feeding of raw materials, the mixing drum 2 cooperates with the dispersion component 8 to stir the raw materials to be processed, the vacuum pump 7 cooperates with the exhaust gas pipe 3 to absorb the exhaust gas in the mixing drum 2, the mixing cylinder 4 is used to provide a high-temperature oxidation environment for the exhaust gas, the water outlet pipe 5 is used to drain the water generated by the oxidation reaction, and the high-efficiency air supply component 9 is used to supply oxygen from all directions inside the mixing cylinder 4 and fully contact the exhaust gas.

[0037] This product is additionally provided with an exhaust gas pipe 3, which cooperates with an exhaust pump to extract the excess exhaust gas in the mixing drum 2 from the top to the mixing drum 4, thereby effectively avoiding direct exhaust gas discharge and pollution of the environment. While stirring, the stirring roller 21 can be used to simultaneously gather the raw materials to the middle, thereby preventing the raw materials from depositing at the bottom. The circulation and dispersion of the raw materials are completed through multiple sets of large-sized stirring rods 17, thereby achieving an efficient dispersion effect.

[0038] The high-efficiency gas supply assembly 9 includes an oxygen tank 10, a first air pump 11, a first gas pipe 12, a direct-connection pipeline 13 and a cross-shaped high-temperature resistant pipe rack 14. The top of the oxygen tank 10 is fixedly connected to the bottom of the first gas pipe 12, the first air pump 11 is installed on the outside of the first gas pipe 12, the direct-connection pipeline 13 passes through the inner wall of one side of the mixing cylinder 4 and is fixedly connected to the output end of the first gas pipe 12, and the cross-shaped high-temperature resistant pipe rack 14 is installed on the outside of the output end of the exhaust gas pipe 3.

[0039] When supplying oxygen, start the first air pump 11 at the top and provide negative pressure conditions.

This makes the oxygen and hot air in the mixing cylinder 4 evenly distributed, prevents the gas from being excessively concentrated in a certain area, and increases the oxidation reaction rate by adding a quantitative sodium carbonate catalyst into the mixing cylinder 4.

[0040] The dispersion assembly 8 includes a stepper motor 15, a corrosion-resistant shaft 16, a stirring rod 17, an alloy collar 18, a transverse lever 19, a sealing cover 20 and a stirring roller 21. The stepper motor 15 is installed in the middle of the top end of the stirring drum 2. The corrosion-resistant shaft 16 passes through the top of the stirring drum 2 and is fixedly connected to the motor shaft of the stepper motor 15 through a coupling. The stirring rod 17 is welded to the outer wall of the corrosion-resistant shaft 16. The alloy collar 18 is sleeved on the outside of the corrosion-resistant shaft 16. The transverse lever 19 is fixedly connected to the outside of the alloy collar 18. The sealing cover 20 is sleeved on one side of the transverse lever 19. The stirring roller 21 is rotatably connected to the outside of the sealing cover 20.

During this process, the servo motor 30 inside the sealing cover 20 is started, and the servo motor 30 drives the stirring roller 21. The upper and lower groups of stirring rollers 21 rotate in opposite directions, so that when the horizontal lever 19 rotates, the stirring roller 21 gathers the raw materials on the upper and lower sides to the middle, thereby disrupting the directional flow effect of the raw materials, and the circulation and dispersion of the raw materials are completed through the large-sized multiple groups of stirring rods 17, so as to achieve an efficient dispersion effect.

[0042] A second air pump 22, a second gas pipe 23, a second direct-connection pipeline 24, a heating box 25 and an electric heating pipe 26 are also provided on one side of the mixing cylinder 4. The top of the heating box 25 is fixedly connected to the bottom of the second gas pipe 23, the second air pump 22 is installed on the outside of the second gas pipe 23, the second direct-connection pipeline 24 passes through the inner wall of one side of the mixing cylinder 4 and is fixedly connected to the output end of the second gas pipe 23, and the electric heating pipes 26 are arranged at equal intervals at the bottom of the heating box 25.

[0043] The outer walls of the direct-connected pipe 1 13 and the direct-connected pipe 2 24 are also provided with a plurality of groups of equally spaced inclined nozzles 27 .

[0044] A temperature detector 28 is also installed on the top of the mixing cylinder 4.

[0045] A slot 29 matching the size of the corrosion-resistant shaft 16 is formed inside the alloy collar 18 .

[0046] The temperature inside the mixing cylinder 4 can be reflected by the numerical value displayed on the temperature detector 28 of the outer shell, and the electromagnetic exhaust valve 34 and the one-way valve 35 ensure the one-way air intake of the first gas pipe 12 and the second gas pipe 23 to prevent gas backflow. When the exhaust gas is passed, the vacuum pump 7 is started to discharge the exhaust gas in the mixing drum 2 from the exhaust gas pipe 3 into the cross-shaped high-temperature resistant pipe rack, and out from the multiple groups of straight nozzles 33 of the array. The gas of the straight nozzle 33 and the oblique nozzle 27 fully intersect, thereby improving the oxidation rate of the exhaust gas and generating carbon dioxide and water. The decomposed water is discharged from the water outlet pipe 5 to the collection device for recycling, thereby saving energy.

[0047] A servo motor 30 is also disposed inside the sealing cover 20 , and a motor shaft of the servo motor 30 is fixedly connected to one end of the stirring roller 21 via a coupling.

[0048] A third air pump 31 and an air inlet pipe 32 are also installed on the outside of the bottom of the heating box 25. The third air pump 31 is installed on the outside of the air inlet pipe 32. The air inlet pipe 32 passes through one side of the heating box 25 and fits tightly with the inner wall surface of the heating box 25.

[0049] A hybrid method for synthesizing perfluorononenyl trifluoroethyl ether is also proposed, which is carried out using the above-mentioned device and comprises the following steps:

[0050] S1, putting the raw materials into the mixing cylinder 4;

[0051] S2, adding a certain amount of sodium carbonate catalyst into the mixing cylinder 4 to increase the oxidation reaction rate;

[0052] S3, the exhaust pump 7 is operated to extract the exhaust gas through the exhaust gas pipe 3, and at the same time, the exhaust gas is oxidized.

[0053] Working principle: When supplying oxygen, start the first air pump 11 at the top and provide negative pressure conditions. The oxygen in the oxygen tank 10 is introduced into the direct-connected pipeline 1 13 through the first air supply pipe 12, and is ejected from multiple groups of oblique nozzles 27. Similarly, the heating box 25 is acted on, and the third air pump 31 is started to introduce air into the heating box 25. The electric heating pipe 26 heats the air. The operating temperature is controlled between 800°C and 900°C. Then start the second air pump 22. The high-temperature gas is introduced into the direct-connected pipeline 2 24 under negative pressure conditions and is ejected from multiple groups of oblique nozzles 27. This makes the oxygen and hot air in the mixing cylinder 4 evenly distributed, preventing the gas from being excessively concentrated in a certain area. By adding a certain amount of sodium carbonate catalyst into the mixing cylinder 4, the oxidation reaction is enhanced. response rate; before stirring, the raw materials are continuously put into the mixing drum 2 from the feed hopper 6, and at the same time, the stepper motor 15 on the top is started to drive the corrosion-resistant shaft 16 to rotate, and the corrosion-resistant shaft 16 drives the outer stirring rod 17 to rotate, and the alloy collars 18 and the horizontal lever 19 opened on the upper and lower sides can rotate synchronously with the stirring rod 17.

The upper and lower groups of stirring rollers 21 rotate in opposite directions, so that when the horizontal lever 19 rotates, the stirring roller 21 gathers the raw materials on the upper and lower sides to the middle, thereby disrupting the directional flow effect of the raw materials, and the circulation and dispersion of the raw materials are completed through the large-sized multiple groups of stirring rods 17, so as to achieve a high-efficiency dispersion effect. The temperature inside the mixing cylinder 4 can be reflected by the numerical value displayed by the temperature detector 28 on the outer shell, and the electromagnetic exhaust valve 34 and the one-way valve 35 ensure the one-way air intake of the first gas pipe 12 and the second gas pipe 23 to prevent gas backflow. When the exhaust gas is passed, the vacuum pump 7 is started to discharge the exhaust gas in the mixing drum 2 from the exhaust gas pipe 3 into the cross-shaped high-temperature resistant pipe rack, and out from the multiple groups of straight nozzles 33 of the array. The gases of the straight nozzle 33 and the oblique nozzle 27 are fully intertwined, thereby improving the oxidation rate of the exhaust gas and generating carbon dioxide and water. The decomposed water is discharged from the water outlet pipe 5 to the collection device for recycling, thereby saving energy.
