Complete Reactor Vessels

This equipment features a corrosion‑ and pressure‑resistant reactor body made of stainless steel/titanium, equipped with a dual‑mode mixing system featuring propeller‑type and turbine‑type agitators. Combined with intelligent temperature control via jacket and coil systems, it enables precise regulation of polymerization reaction temperatures. Multiple feed inlets support the precise proportioning of raw materials such as ethylene oxide and propane, while built‑in nitrogen purging and safety relief devices ensure oxidation protection and overpressure safeguarding. Specifically designed for the production of polyether polyols and other polymers, this equipment utilizes vacuum dehydration, staged feeding, and closed‑loop temperature control processes to achieve continuous, high‑efficiency synthesis. It is widely applicable across the daily chemical, pharmaceutical, and polymer materials industries, balancing capacity enhancement with intrinsic safety.

Product Description

Structure

Reactor vessel:

Stainless steel, titanium, and other corrosion‑resistant, high‑temperature‑resistant materials are often used to withstand high temperatures, high pressures, and chemical corrosion.

Mixing device:

It consists of a mixer and a搅拌 shaft. Common types of mixers include propeller-type and turbine-type mixers, which can ensure uniform mixing of reactants, enhance mass and heat transfer, and improve reaction efficiency.

Heating and Cooling Systems:

Generally, there are two types: jacketed reactors and internally coiled tube reactors. They control reaction temperature by introducing heating media such as steam or thermal oil, or cooling media such as water.

Inlet and outlet:

It includes a feed inlet and a discharge outlet; the feed inlet typically has multiple ports, allowing for precise control of the proportions and addition sequence of different raw materials, while the discharge outlet is used to remove the final product.

Safety accessories:

Such as safety valves and pressure sensors—safety valves can prevent excessive pressure inside the reactor from causing hazards, while pressure sensors monitor pressure data in real time.

Working Principle

In the operation of a polyether reactor, the initiator is first pre‑mixed with the catalyst to form metal alkoxide compounds. After vacuum dehydration, the mixture is fed into the reactor, and dry nitrogen is then introduced to displace the air inside the reactor and prevent oxidation. Subsequently, raw materials such as ethylene oxide and propylene oxide are added according to the specified proportions. A stirring device ensures thorough mixing of the reactants, while the heating and cooling systems maintain the reaction temperature. Under appropriate temperature and pressure conditions, the reactants undergo ring-opening polymerization to produce polyether compounds. Once the reaction is complete, the product is discharged through the outlet, after which the reactor is cleaned in preparation for the next reaction.
