Basic structure and function of explosion-proof double-layer glass reaction kettle
Date: 2025-10-17Read: 3
Explosion proof double-layer glass reactor is a laboratory or small-scale production equipment widely used in industries such as chemistry, pharmaceuticals, food, and environmental protection. It adopts a double-layer glass design, with the inner reaction vessel used for chemical reactions and the outer layer of glass used to isolate the external environment, avoiding the pollution of volatile gases from reactants to the environment. At the same time, explosion-proof design ensures that explosion accidents will not occur under high temperature, high pressure or other special conditions, which is one of the very important equipment in modern laboratories and pilot production.
Explosion proof double-layer glass reactorThe basic structure:
1. Inner layer glass: Inner layer glass is usually made of high temperature resistant and corrosion-resistant materials, such as high borosilicate glass. The main function of inner glass is to carry reactants and undergo chemical reactions, so its heat resistance and chemical resistance are crucial.
2. Outer layer glass: Outer layer glass is usually made of high borosilicate glass, which has strong compressive strength. The main function of outer glass is to isolate the external environment and prevent the leakage of harmful gases that may be generated during the reaction.
3. Interlayer space: The interlayer space between the inner and outer layers of glass is usually filled with thermal oil or water to control the temperature of the reaction vessel. This design can precisely adjust the reaction temperature during the reaction by circulating heating or cooling media, ensuring the stability and safety of the reaction process.
4. Stirring device: The double-layer glass reactor is equipped with a high-speed stirring device, and the stirring speed can be adjusted according to experimental needs to ensure uniform mixing of reactants and avoid incomplete or slow reaction rates.
5. Sealing system: The upper part of the reaction vessel is usually equipped with a sealing system to ensure that there is no gas leakage during the reaction process, especially under high pressure or toxic gas conditions.
6. Explosion proof design: Explosion proof design is very important. Explosion proof design can effectively prevent equipment rupture or explosion under high pressure or large temperature fluctuations. Reactors are usually equipped with safety devices such as pressure relief valves and rupture discs to prevent equipment from becoming dangerous due to excessive pressure.
Advantages of explosion-proof double-layer glass reaction kettle:
1. High safety: The explosion-proof design and multiple safety devices make the reactor safer when operating under high temperature, high pressure, or hazardous chemical reaction conditions, avoiding explosion accidents caused by equipment failure.
2. Strong corrosion resistance: The double-layer glass reaction vessel uses high borosilicate glass, which has strong corrosion resistance and can be used for a long time in strong acids, strong alkalis, or other highly corrosive reactants.
3. Accurate temperature control: Through the heat exchange system in the interlayer space, the reaction kettle can accurately control the reaction temperature, ensuring the stability of the reaction process and the quality of the reactants.
4. Efficient stirring: The strong stirring system can ensure thorough mixing of reactants, avoid local overheating or uneven reaction, and improve reaction efficiency.
5. Transparent design: The double-layer glass design visualizes the reaction process, allowing operators to observe the reaction situation in real time and adjust operating conditions in a timely manner.
