Description

Technical Field

[0002] "Distillation equipment" is a separation technology carried out under high vacuum conditions. It has the characteristics of low distillation temperature, high system vacuum, short material heating time, high separation degree, etc. The separation process is irreversible and there is no boiling bubbling phenomenon. In the process of distillation, the liquid needs to be filtered through a filtering mechanism. During distillation, the "acid synthesis process route" is the first step of bromination. The operation steps are: add sulfuric acid to the reactor, drip fluorobenzene, cool down while dripping, add hydantoin, cool down and stratify, react at low temperature to obtain bromobenzene; the second step of cyanidation is the operation steps: add cuprous cyanide, reflux reaction, distill at above 150℃, negative pressure 70℃, add water and stratify; the third step of alkaline hydrolysis is the operation steps: put cyanobenzene into the reactor, drip sodium hydroxide aqueous solution under reflux, cool down after dripping, adjust acid, and filter. When the existing filtering mechanism is in use, when it is necessary to clean the filter element inside the filtering mechanism, because the filter is an integrated structure, it is more troublesome to disassemble the filter element, and a large number of tools are required. For this reason, we propose a filtering mechanism. Utility Model Content
