Background
The filtration is an operation of separating solid and other substances from liquid (or gas) by making the liquid (or gas) in suspension (or solid particle-containing heating gas) permeate through the medium and making the solid particles and other substances be retained by the filter medium under the action of a driving force or other external forces. Filtration is typically carried out in various filtration devices.
During or after the chemical reaction, it is usually necessary to post-treat it with a filtration device. However, the existing filtering device is usually operated at normal temperature, and when liquid needing hot filtration is filtered, because the filtering device treats the normal temperature state, the compound is easy to generate crystallization phenomenon in the filtering process, thereby not only affecting the yield of the product, but also affecting the filtering effect. When some low-temperature or extremely low-temperature liquids are filtered, the filtering device still treats the normal temperature state, so that the compounds are extremely easy to damage in the filtering process, and the product quality is influenced.
