High-pressure reactors are composed of components such as electric motors, reducers, magnetic drive units, end caps, cylindrical bodies, jackets, and agitators.
The magnetic drive unit is a typical innovation for autoclaves, fundamentally solving the shaft seal leakage problem that previous packing and mechanical seals could not overcome. It ensures no leakage or contamination, making it an ideal device for high-temperature and high-pressure chemical reactions in China. It particularly excels in reactions involving flammable, explosive, or toxic media. It is widely used in industries such as oil, chemicals, rubber, pesticides, dyes, and food to complete processes like vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.
Structural Features:
Specifications: 50L, 100L, 200L, 300L, 500L, 1000L, 1500L, 2000L, 3000L, 5000L, 8000L, 10000L, 20000L, etc.
Material: The high-pressure reactor mainly uses composite panels, with commonly used basic materials being Q345R for the core panels and materials such as S31603, S30408, S32168, Hastelloy, nickel, titanium, Inconel, zirconium, and other non-ferrous metals. Pure stainless steel can also be used.
Agitator: A strong magnetic rotary coupling structure (magnetic drive unit) made of rare-earth permanent magnets, with the basic manufacturing materials of the magnetic drive unit being ferromagnetic substances (ferrous alloys, nickel alloys). There is almost no loss of magnetic field when passing through the sealed alloy layer. Therefore, the rotating magnetic field generated by the external permanent magnet can be effectively received by the internal permanent magnet rotor, thus driving the agitator components inside the reactor to mix materials. The agitator speed ranges from 0 to 300 rpm, or even higher, and can be equipped with various propellers such as propulsion, paddle, anchor, frame, and spiral blades.
Heating: Common heating methods include jacketed (semicircular tube) external circulation heating and electric heating, with circulating media such as steam and thermal oil.
Safety: The high-pressure reactor is equipped with a safety valve or bursting diaphragm, featuring minimal bursting value error, rapid exhaust speed upon bursting, and is highly reliable.
Polishing: The inner surface of the vessel, as required, can be mirror polished.
Dish Cover: Common structures for dish covers include flat covers and dome-style covers. The openings on the dish cover can be designed according to customer requirements.
Caution for using high-pressure reactors (hydrogenation reactors):
For initial operators of autoclaves, at least one person must be present who is proficient in autoclave operation.
2. Personnel operating on-site must wear cotton gloves and shoes without nails.
3. Do not carry items such as mobile phones, lighters, MP3 players, etc., which can cause explosions or spontaneous combustion, into the hydrogenation work area.
4. Operators handling tools and parts near the hydrolysis process should handle them gently to avoid rigid impacts that could cause sparks.
5. During pressure relief, the exhaust from high-pressure reactions should be directed outdoors through a flexible hose or into a fume hood.
