[0025] High-temperature heating liquid is injected into the coil 14 through the heating liquid inlet 16, so that the heating liquid heats the heating chamber 13 and controls the temperature in the reactor. The cooled liquid flows out from the heating liquid outlet 15, and the buckle 19 on the ring shaft 18 buckles the sealing cover plate 22, so that the sealing cover plate 22 and the buckle 19 fit tightly. The air pressure detector 23 and the temperature detector 25 on the reactor cover 2 will monitor the air pressure and temperature in the reactor in real time. The pressure relief valve 26 controls the air pressure in the reactor body 1, and the situation of the reactants can be observed through the observation hole 24, so that the situation in the reactor can be observed and processed at any time.

The top of the base 263 is fixedly connected with a spring 262, and the top of the spring 262 is fixedly connected with the top of the inner cavity of the pressure relief valve body 261.

After the spring 262 contracts, the block 265 contracts and opens the air vent 269, and the compressed gas is released. After the air pressure returns to normal, the spring 262 rebounds, and the pressure-regulating sealing ring 266 and the sealing ring 264 on the equipment play a sealing role. At the same time, different pressure-regulating sealing rings 266 are replaced to reduce or increase the contact area of ​​the compressed gas on the sealing ring 264 to control the pressure, thereby enhancing the sealing performance and safety of the equipment.

[0028] like Figure 6 As shown, the utility model provides a novel saponification acid hydrolysis reactor, the stirring device 3 includes a motor 31, the bottom end of the motor 31 is fixedly connected with a reducer 32, the bottom end of the reducer 32 is fixedly connected with a bracket 34, the bottom end of the bracket 34 is fixedly connected to the top of the outer wall of the kettle cover shell 21, the output shaft of the reducer 32 is fixedly connected with a coupling 33, the bottom end of the coupling 33 is fixedly connected with a stirring shaft 35, the outer wall of the stirring shaft 35 is sleeved with a shaft seal 36, the bottom end of the shaft seal 36 is connected to the top of the outer wall of the kettle cover shell 21, the bottom of the stirring shaft 35 passes through the top shell of the kettle cover shell 21 and is fixedly connected with a plurality of stirring paddles 37 arranged from bottom to top.

[0029] When the stirring device 3 is turned on, the motor 31 rotates, and the reducer 32 at the bottom reduces the rotation speed, the output shaft drives the stirring paddle 37 on the stirring shaft 35 to rotate slowly through the coupling 33, and the stirring shaft 35 seals the gap between the stirring shaft 35 and the kettle cover shell 21. The slow stirring speed is more suitable for the saponification acidolysis reaction.

[0030] The working principle of the new saponification acid hydrolysis reactor is described in detail below.

[0031] like Figure 1-6 As shown, high-temperature heating liquid is injected into the coil 14 through the heating liquid inlet 16, so that the heating liquid heats the heating chamber 13 and controls the temperature in the reactor. The cooled liquid flows out from the heating liquid outlet 15, and the buckle 19 on the ring shaft 18 buckles the sealing cover plate 22, so that the sealing cover plate 22 and the buckle 19 are tightly fitted. The air pressure detector 23 and the temperature detector 25 on the reactor cover 2 will monitor the air pressure and temperature in the reactor in real time. The pressure relief valve 26 controls the air pressure in the reactor body 1, and the situation of the reactants can be observed through the observation hole 24. In this way, the situation in the reactor can be observed and processed at any time. After the reaction raw materials are injected into the reactor, the rotating disk 273 is rotated, and the sealing base 274 and the bottom of the feed valve body 271 are tightly fitted through the threaded connection between the valve stem 272 and the feed valve body 271 to achieve a sealing effect. When the air pressure in the reactor is too high, the compressed gas pushes the base 263 through the air inlet 267 and the compressed gas passage 268. After the spring 262 contracts, the block 265 contracts to open the vent hole 269, and the compressed gas is released. After the air pressure is normal, the spring 262 rebounds, and the pressure regulating sealing ring 266 and the sealing ring 264 on the equipment play a sealing role. At the same time, different pressure regulating sealing rings 266 are replaced to reduce or increase the contact area of ​​the compressed gas on the sealing ring 264 to control the pressure, thereby enhancing the sealing performance and safety of the equipment. The stirring device 3 is turned on, the motor 31 rotates, and the reducer 32 at the bottom will reduce the speed. The output shaft drives the stirring paddle 37 on the stirring shaft 35 to rotate slowly through the coupling 33. The stirring shaft 35 will seal the gap between the stirring shaft 35 and the reactor cover shell 21. The slow stirring speed is more suitable for saponification acidolysis reaction.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
