High-pressure reactor

A high-pressure reactor, comprising:

• a reactor, which is provided with a feed inlet at one end and a discharge outlet at the other end, the feed inlet is used for injecting slurry, steam, and acid, while the discharge outlet is used for discharging;
• inside the reactor, several partition plates are arranged sequentially along the direction of material flow;
• these partition plates divide the interior cavity of the reactor into multiple compartments;
• each compartment is equipped with a mixing device;
• the upper parts of any two adjacent compartments are connected;
• a feed inlet, which comprises an ore pulp inlet, a steam inlet, and an acid inlet that are sequentially arranged circumferentially along the direction of stirring rotation with the mixing device as an axis;
• and,
• a mixing device, which comprises a driving component, a propeller stirring paddle, and a disc disperser stirring paddle;
• the driving component is used to drive the rotation of the propeller stirring paddle and the disc disperser stirring paddle;
• the disc disperser stirring paddle is located above the propeller stirring paddle;
• the propeller stirring paddle is used to disturb and mix the materials and promote their upward movement;
• the disc disperser stirring paddle is used to tangentially disperse the upward-moving materials.
