How to Use a High-Pressure Reactor Safely

1.Check the power supply, cooling water system, and valve status.
2. Filling procedure:
    ⑴ Add reactants through the upper inlet (not exceeding 3/4 of the reactor volume).
    ⑵Tighten bolts diagonally with a small wrench, then moderately with a large wrench (avoid over-tightening).
3.Ensure all valves (exhaust, inlet, outlet, etc.) are closed but not overtightened.
4. Insert the thermocouple and turn on the control box power and display.

1. Turn on cooling water and adjust stirring speed.
2. Begin the heating program (heating rate ≤80°C/hour).
3. Monitor pressure, temperature, speed, and torque in real time (prioritize pressure tracking).

1. Set temperature to room temperature for natural cooling.
2.Depressurization sequence:
  ⑴ Slowly open the upper exhaust valve to release pressure to zero.
  ⑵Close the exhaust valve.
  ⑶ Discharge material via the bottom valve.
  ⑷Clean residues with solvent.

1.When removing the lid, loosen bolts symmetrically to protect the sealing surface.
2. Thoroughly clean the reactor body, lid, and sealing surfaces (avoid abrasive tools).
3. Disassemble and clean the stirrer.
4. Keep all valves dry.

1.Align the reactor body and lid.
2.Secure the ferrule (do not tighten bolts yet).
3.Inspect the sealing ring for damage.
4. Tighten bolts diagonally in stages (moderate torque only).
5. Leak Test procedure:
  ⑴ Use inert gas (never oxygen or flammables).
  ⑵ Pressurize incrementally (20% working pressure per step, 5-minute holds).
  ⑶ Test at 105% working pressure for 30 minutes.
  ⑷ Check for leaks throughout the test.

1. Always operate with ≥2 personnel.
2. Never leave the reactor unattended.
3. Prohibited actions:
  ⑴ Exceeding temperature/pressure limits.
  ⑵ Tightening nuts or striking the reactor under pressure.
  ⑶ Rapid cooling/heating (risk of thermal stress cracks).
4. If leaks occur:
  ⑴Stop heating immediately.
  ⑵ Cool the system.
  ⑶Depressurize before addressing the issue.
5.For long-term storage:
  ⑴ Drain all heat transfer oil.
  ⑵ Never mix old and new oil.
6.Maintain proper ventilation.
7.Ensure explosion-proof facility design.
8. Verify proper grounding of all equipment.

1. For abnormal pressure/temperature:
  ⑴ Immediately stop heating.
  ⑵ Vent pressure slowly.
2. For seal failure:
  ⑴ Depressurize completely first.
  ⑵ Inspect all sealing surfaces.
  ⑶ Replace damaged seals as needed.

1.Always obtain supervisor approval before operation.

2.Strictly adhere to all safety protocols.
