Description

Technical Field

[0001] The utility model relates to the technical field of distillation kettles, in particular to a pressure relief mechanism for distillation kettles. Background Art

[0002] Some reactors or distillation kettles often work under high pressure due to the needs of chemical or environmental protection reaction processes. When the reaction is completed and materials are discharged or the device is overhauled, smoothly releasing the pressure in the kettle becomes an important process to achieve safe production. For this reason, people have specially designed various types of reactor pressure relief devices. The most widely used one is the labyrinth pressure relief device. The so-called labyrinth pressure relief device is a device in which a large number of partitions are arranged in the main body of the pressure relief tank shell. A large number of gaps are provided between the partitions and between the partitions and the inner wall of the pressure relief tank shell. All the gaps are arranged in an alternating manner to form a labyrinth for gas release. The high-pressure gas twists and turns in the labyrinth, and its high-pressure potential energy is released more completely. When it flows out of the pressure relief device, it is very stable, and does not cause production hazards entirely due to its high temperature and high pressure. Although this device has high pressure relief efficiency and stable performance, its labyrinth gap can still be penetrated by the foam contained in the material. When treating some impurities with viscosity or containing tiny solid particles, such as municipal sewage, industrial sewage, etc., it is inevitable that foam will be generated by the material to be treated and rush out with the gas, causing hidden dangers of malfunction and polluting the working environment. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the creation of this case. Utility Model Content
