Cleaning requirements of high pressure reactor
Editor's note: The high-pressure reaction kettle is a typical innovation of magnetic transmission devices used in large-scale reaction equipment. After the autoclave is used, it should be cleaned in time to avoid some residues corroding the autoclave. So, what should be paid attention to when cleaning it? The high-pressure reaction kettle is a typical innovation of magnetic transmission devices applied to large-scale reaction equipment. It fundamentally solves the problem of shaft seal leakage that cannot be overcome by the previous packing seals and mechanical seals. The most ideal device for chemical reaction, especially for the chemical reaction of flammable, explosive and toxic media, shows its superiority. Pay attention to the following points when cleaning the autoclave: 1. Charge the reaction solvent into the kettle from the exhaust valve. After cleaning most of the residue, inject water into the kettle and stir for 10 minutes. At this time, the kettle lid can be opened to clean the inner wall of the kettle. 2. When cleaning, the kettle lid and sampling valve must be cleaned, and at the same time, when there is water in the kettle, a little nitrogen is charged. 3. For the reaction kettle that is not used temporarily, it is best to add 70% volume of absolute ethanol to the reaction kettle for soaking, without tightening the screws. After cleaning the autoclave, it will be convenient for the next use.
