Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettles, and specifically relates to a double-layer quartz reaction kettle. Background Art

[0002] Quartz is used as the main material of the reactor due to its corrosion resistance, insolubility in organic solvents, high hardness, high transparency and other characteristics. It is used in reactions involving corrosive or organic solutions to facilitate observation of the reaction process and reaction effect. At the same time, since the quartz material itself is relatively brittle, it cannot be machined, and many interfaces cannot be processed. It is not convenient to install agitators, valves, temperature sensors, pressure sensors, etc., which makes the application range of quartz reactors relatively narrow. Although the existing double-layer glass reactor also has the effects of high transparency and easy observation, due to its molding process and other reasons, it is impossible to achieve high-precision interfaces like metal materials, and the sealing effect under high temperature and high pressure conditions is difficult to achieve.

[0003] Therefore, it is necessary to provide a reactor that can overcome the shortcomings of quartz material, which is brittle and cannot be machined. Utility Model Content
