Reaction kettle, also known as reaction tank or reactor, is an indispensable key equipment in chemical, pharmaceutical, food and new material industries. As a kind of container used to realise chemical reactions, it can withstand a certain pressure and temperature to ensure that chemical reactions are carried out smoothly under specific conditions. In this article, we will delve into the structure, working principle, types, applications, as well as safety and maintenance of the reactor.
Reactor usually consists of kettle body, stirring system, heating and cooling system, sealing device, transmission device and safety accessories. The kettle is the main place of chemical reaction, usually made of stainless steel, carbon steel or glass-lined materials to adapt to different reaction conditions and material characteristics. Stirring system is used to make the reaction materials fully mixed to improve the reaction rate and uniformity. The heating and cooling system controls the reaction temperature by means of jacket or inner coil. The sealing device ensures that the reaction is carried out in an airtight environment, preventing leakage of the reactants and the entry of external impurities. The transmission device drives the stirrer to rotate, while the safety accessories include pressure gauges, thermometers, safety valves, etc., which are used to monitor and control the reaction process in real time.
The working principle of reactor is based on the principle of chemical reaction. The reactants are added into the kettle, and the heat required for the reaction is provided by the heating device, so that the reactants under the action of catalyst undergo a chemical reaction to generate the required products. At the same time, the stirring device continuously agitates the reaction materials to mix them thoroughly. The cooling device is used to control the reaction temperature and prevent the reaction from overheating. The control system can monitor and control the temperature, stirring speed, pressure and other parameters of the reactor in real time to realise the automatic control of the reaction process.
According to different needs and reaction substances, reactor is divided into many types. According to the heating method, it can be divided into electric heating reactor, hot water heating reactor and thermal oil circulation heating reactor, etc.; according to the cooling method, it can be divided into jacket cooling and kettle coil cooling reactor; according to the material, it can be divided into carbon steel reaction kettle, stainless steel reaction kettle, glass-lined reaction kettle and steel-lined reaction kettle, etc.; according to the pressure, it can be divided into atmospheric reaction kettle, positive-pressure kettle and negative-pressure kettle; according to the stirring method, it can be divided into paddle stirring reaction kettle and anchor paddle stirring reaction kettle, etc.; according to the installation method, it can be divided into vertical reactor and horizontal reactor, etc. reaction kettle, anchor paddle stirring reaction kettle, etc.; according to the installation mode can be divided into vertical reaction kettle and horizontal reaction kettle. Each type of reactor has its own specific application scenario and advantages.
Reactor is widely used in petroleum, chemical, rubber, pesticide, dyestuff, medicine and food, etc. It is used to complete the process of sulphurisation, nitrification, hydrogenation, hydrocarbonation, polymerisation, condensation and so on. It is a comprehensive reaction vessel, capable of realising the heating, evaporation, cooling and low-speed mixing reaction functions required by the process. The reaction kettle plays a pivotal role in chemical production, and is of great significance in improving production efficiency, ensuring product quality and production safety.
As a dangerous pressure vessel, the reactor is prone to leakage of flammable and explosive and other dangerous gases in industrial production. Therefore, it is crucial to ensure the safe operation of the reaction kettle. Operators should strictly comply with the operating procedures, according to the working pressure and working temperature marked on the product nameplate, to avoid overload operation. At the same time, the reactor should be regularly inspected and maintained, including checking the wear and tear of the stirrer, seals, heater, cooler and other parts, cleaning the inside of the reactor, lubricating and checking the mechanical parts. In addition, regular safety inspection and performance test should be carried out on the reactor, including pressure test, leakage test, temperature control system test, etc., to ensure the safe operation of the equipment.
To sum up, as a key equipment in chemical production, the reactor has a complex structure and various functions. Understanding and mastering the structure, working principle, type and application of reaction kettle is of great significance for improving production efficiency, guaranteeing product quality and ensuring production safety. In the future, with the continuous progress of technology and process optimisation, the performance and intelligent level of reaction kettle will be further improved to provide stronger support for the development of related industries.
