Stainless Steel Closed Reaction Kettle

Aix Boiler stainless steel closed reaction kettle operates based on the principle of closed pressure reaction, jacket/coil heat exchange and mechanical stirring mixing. In a fully closed stainless steel kettle body, it provides a stable and controllable reaction environment for materials by precisely controlling temperature, pressure, stirring speed and feeding sequence, completing various chemical reactions and processes such as polymerization, condensation, vulcanization, nitration, hydrogenation, neutralization, crystallization and distillation. The kettle body is made of high-quality 304/316L stainless steel, with mechanical seal to realize closed and leak-free operation in the whole process. The heating/cooling system realizes rapid heat exchange through jacket or internal coil, and the stirring system makes material mixing more uniform. The whole kettle is designed and manufactured in strict accordance with the standards of China Boiler and Boiler Water Treatment Association, GB/T 150 Pressure Vessels and TSG 21-2016 *Supervision Regulation on Safety Technology for Stationary Pressure Vessels*, featuring safe pressure resistance, corrosion resistance, hygiene and stable operation. As the core chemical equipment of Aix Boiler brand, this product is independently developed, produced and inspected by the original factory with full-chain quality control. The structure, material, heating method and stirring form can be customized, providing standardized and customized reaction vessels for chemical, pharmaceutical, food, coating, new materials, scientific research and other fields to meet process scenarios with high temperature, high pressure, strong corrosion and high hygiene requirements.

1. Core Product Parameters (Aix Stainless Steel Closed Reaction Kettle)

2. Working Principle & Technical Core

Aix stainless steel closed reaction kettle consists of eight core parts: kettle body, kettle cover, jacket/coil heat exchange system, stirring system, sealing system, transmission system, support legs and inlet/outlet pipeline system, belonging to typical closed pressure reaction equipment. During operation, materials enter the closed kettle from the feed port, and valves are closed to form a closed reaction space. The stirring motor drives the stirring paddle to rotate, making materials fully mixed and dispersed, eliminating concentration difference and local overheating. The heat exchange system feeds steam, heat transfer oil, cooling water or frozen brine through the jacket or internal coil to precisely control the reaction temperature. The pressure system maintains stable pressure in the kettle through pressure gauge, safety valve and vent valve, automatic pressure relief when overpressure, vacuum for negative pressure. Mechanical seal ensures no leakage during stirring shaft rotation, especially suitable for toxic, flammable, explosive and volatile materials. The equipment can be equipped with PLC intelligent control system to realize automatic control of temperature, pressure, speed, feeding and discharging, meeting high-precision, automatic and continuous production requirements.
