The principle and structure of double-layer glass reaction kettle
Date: 2024-08-20Read: 6
Double layered glass reactor is a type of reactor equipment widely used in chemical laboratories, pharmaceutical factories, and chemical plants. The process principle and operation flow are very important for experimental personnel. This article will introduce the basic structure, principle, operation process, and common maintenance methods of double-layer glass reaction vessels, in order to better understand their applications.
Working principle of double-layer glass reactor:
After adding the reagent to the reaction vessel, mix the reactants thoroughly by stirring. At this point, by controlling factors such as temperature, reaction time, and stirring speed, the experimenters can control the reaction inside the reactor. During the reaction process, the temperature of the reaction vessel is controlled by circulating cooling water connected through pipelines. For chemical reactions with higher requirements, a vacuum pump is needed to remove the volume of gas from the reaction vessel. This can avoid the influence of gas during the reaction process.
The main structure of a double-layer glass reactor consists of an outer layer glass reactor and an inner layer glass reactor. The outer glass reactor can provide insulation and heat preservation, while the inner glass reactor can withstand chemical reactions and stir. Usually, the reaction vessel is also equipped with temperature control system, stirring mechanical system, sensors and other accessories. The equipment mainly consists of an inner liner, an outer liner, a heating jacket, a cooling jacket, a mixer, and other parts. The specific structure is as follows:
1. Inner liner: Made of high borosilicate glass material, with optional capacity, strong corrosion resistance and high temperature stability.
2. External gallbladder: Made of high-quality stainless steel, it has good corrosion resistance and certain insulation performance.
3. Heating jacket: Surrounded between the outer and inner chambers, it can achieve heating, constant temperature and other functions through electric heaters or jacket heat exchange.
4. Cooling jacket: Also enclosed between the outer and inner chambers, it can achieve rapid cooling by circulating cooling water.
5. Blender: Used for mixing reaction materials, its speed can be adjusted during the experimental process.
