The special material reactor is a reactor vessel made of no special materials. The shaft seal form of the reactor is magnetic transmission static seal, packing seal, and mechanical seal. The heating methods are infrared electric heating, jacket circulating steam/heat conduction oil heating and heat conduction. Oil electric heating, etc., the cavity material can be made according to different media requirements Hastelloy cavity, nickel-based alloy cavity, pure nickel cavity, pure titanium cavity and various composite materials, and to undertake supporting stainless steel, carbon steel production High-pressure reactor and fermentation tank, feed tank, heat exchanger, homogeneous reactor and non-standard chemical equipment are manufactured. According to the user's medium and process requirements, the size of the magnetic coupling and the reactor can be arbitrarily selected.
