[0024] The working principle of this utility model:

[0025] First, place the equipment on a level surface and introduce inert gas into the inert gas tank 301 through the air inlet 304. The operator controls the gas booster motor 505 to start using the CNC 602, and increases the internal pressure of the inert gas tank 301 through the gas connection pipe 503. Then, flip the sealing cover 403 to the left to open it. Mix an appropriate amount of p-nitrophenol and water in a certain proportion, and add it into the hydrolysis tank 201 through the feed inlet 402 and close the sealing cover 403.

[0026] Next, the operator starts the stirring motor 203 via the CNC 602. The output shaft of the stirring motor 203 drives the transmission shaft, which in turn drives the stirring rod 205 and the heater 206 to rotate, so that the reactants are evenly mixed in the pressure cylinder. The heater 206 is started and the temperature is set. As the temperature rises, p-nitrophenol begins to undergo a hydrolysis reaction. At the same time, the gas supply motor 306 is started via the CNC 602. The output shaft of the gas supply motor 306 drives the transmission shaft, which in turn drives the blocking device 307 to rotate, so that the gas supply hole 308 on the blocking device 307 is connected to the gas supply pipe 302, allowing the inert gas in the inert gas tank 301 to enter the hydrolysis tank 201 through the gas supply pipe 302, providing an inert environment for the hydrolysis process. When the temperature reaches the set value, the hydrolysis booster motor 504 is started via the CNC 602 to apply a certain pressure to the mixture in the hydrolysis tank 201, which is beneficial to promote the hydrolysis reaction and improve the reaction rate and product yield.

[0027] Finally, the pressure and temperature in the hydrolysis tank 201 and the inert gas tank 301 are detected by the gas pressure sensor 603, the hydrolysis pressure sensor 604, and the temperature sensor 605, respectively. If the pressure and temperature are abnormal, the feedback will be displayed on the display on the CNC 602, so that the staff can make timely adjustments by controlling the corresponding devices through the CNC 602 to ensure the effective hydrolysis of p-nitrophenol. After the hydrolysis is completed, the hydrolyzed product is discharged through the discharge port 207.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
