One. Structural Features of the External Semi-tube Type Reactor

The external half-tube reaction kettle is mainly composed of the cylinder, top and bottom covers, external half-tube, agitator, bottom support and transmission unit, shaft seal unit, etc. The cylinder and covers are sealed with large flanges or directly welded together. The lower part of the cylinder is equipped with a discharge valve and heating pipes. The top cover features an inlet, vacuum, distillation, sight glass observation, temperature measurement, and safety venting ports. Bracket connection seats are welded on top, where brackets, shaft seals, reducers, and motors are mounted. The external half-tube has openings for oil inlet and outlet, temperature measurement, venting valves, and other pipeline connections. Due to varying production processes and operating conditions among customers, there are different requirements for the top cover process openings, agitator type, support type, and sealing devices. Our company can design according to the customer's specific process requirements. Notable advantages of the external half-tube reaction kettle include rapid heating and cooling speeds, high pressure resistance of the half-tube and inner cylinder.

Part II: Purpose of External Half Shell Reactor

The reactor is widely used in industries such as unsaturated resins, saturated resins, polyester, acrylic emulsion, epoxy resin, polyurethane, thermoplastic adhesive, TPU, PUR, polyols, oils, and other fine chemicals, paints and inks, adhesives, petrochemicals, and food and beverage. It is mainly used for reactions, polymerization, distillation, and concentration in these industries.

Section 3: Outer Seamless Tube Reactor Material

General materials for reaction kettles include carbon steel, stainless steel 304, stainless steel 321, acid and alkali-resistant stainless steel 316L, high-temperature-resistant 310S, enamel, titanium, and zirconium, etc.

IV. External Half Shell Reactor Agitation Type

The agitator types for reactors include: helical, anchor, frame, propulsion, turbine disc, single (double) spiral, and various combined blade configurations. These can be optimized through advanced mixing software tailored to the characteristics of the customer's product, and we offer efficient blade designs based on our years of production experience.

V. External Half Shell Reactor Axial Seal Type

The sealing types for reaction kettles include magnetic sealing and mechanical sealing. Our company can provide the appropriate sealing type based on the customer's production process, ensuring satisfactory results during use.
