Description

Technical Field

[0001] The utility model relates to the technical field of pressure reactors, in particular to a leakage protection device for a pressure reactor. Background Art

[0002] A pressure reactor is a device used to carry out chemical reactions. It usually consists of a sealed container and a corresponding control system. The main feature of a pressure reactor is that it can carry out various reactions under high pressure and high temperature conditions. It can withstand high pressure environments, usually reaching pressures of tens to hundreds of atmospheres. Pressure reactors usually have temperature and pressure control functions, and can control reaction conditions through heating or cooling systems and gas or liquid pressurization to meet the needs of different reactions.

[0003] Existing reactors are widely used in laboratory research and large-scale production of various chemical reactions. They provide a controlled environment that allows chemical reactions to proceed under specific temperature, pressure and stirring conditions. Some common chemical reactions in industry include synthesizing chemicals, preparing drugs, producing petrochemical products, etc., so it is necessary to propose a new solution.

[0004] The existing reactor feeding pipe is connected to the feeding pipe through a flange. The chemical reaction in the reactor will generate a large amount of heat and gas, which makes the equipment in a state of high temperature and high pressure during operation. After long-term use, its sealing ring ages. In the environment of high temperature and high pressure, there will be hidden dangers of leakage, thus causing safety accidents. In order to improve the safety of the pipeline connection, we propose a pressure reactor leakage protection device. Utility Model Content
