Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of fractionation technology, and specifically relates to a fractionation device for preparing dihydromenthone. BACKGROUND

[0002] In the chemical industry, dihydromenthone is an important organic compound, and through fractionation operation on the mixture after reaction, the effective separation of target product dihydromenthone and other impurities or by-products is realized according to the boiling point difference of different components, so that high-purity dihydromenthone is obtained.

[0003] According to the search, the publication (announcement) No. CN212548357U discloses a fractionation device for preparing dihydromenthone, which discloses the technical scheme of "including a connecting pipe, a conveying pipe, a driving machine, a cover, a collecting tank, a supporting foot, a distillation tank, a connecting branch pipe and a conversion tank. The utility model discloses a fractionation device for preparing dihydromenthone. When gas is generated by distillation of the distillation tank, the gas passes through the air pipe on the cover shell to the pressure tank, pushes the extrusion block to slide on the sliding groove, so that the extrusion block exerts a certain pressure on the sealing ring. The more gas in the distillation tank, the greater the pushing force of the extrusion block on the sealing ring, so that the inner ring part of the sealing ring is tightly connected with the distillation tank connecting block at the top of the distillation tank".

[0004] However, during the fractionation reaction, gas pressure is generated in the reaction tank. If the gas pressure is too high, it will cause a huge pressure load on the reaction tank body, which may cause deformation, rupture and other serious safety accidents of the tank body, endanger the life safety of the operating personnel and cause equipment damage and production interruption. Therefore, in order to protect the safety of the tank body, when the gas pressure exceeds a certain threshold, pressure relief treatment must be carried out to reduce the pressure in the tank by releasing part of the gas, so that it is maintained within a safe range. With the release of gas, the pressure acting on the sealing ring will decrease rapidly. At this time, the sealing ring may not be able to quickly recover to the initial sealing state, or it may have a certain degree of fatigue deformation due to the previous long-term extrusion, resulting in a decrease in sealing performance. Therefore, the remaining gas in the reaction tank may still leak out through the gap of the sealing ring under the action of the pressure difference, which poses a serious threat to the environment and personnel safety.

[0005] To solve the above problems, a fractionation device for preparing dihydromenthone is provided in the present application. Utility model content
