The short-range molecular distillation device is an efficient separation equipment, and its operation and maintenance are crucial to ensure the normal operation and service life of the equipment. The following is a guide for the operation and maintenance of short-range molecular distillation equipment: Operation guide Preparation: Ensure equipment cleanliness and check for damaged or loose parts. Prepare the mixture to be separated and ensure it is within the operating temperature range. Assembly equipment: Install the distillation flask on the distillation column and ensure good sealing. Connect the condenser to the top of the distillation column and connect the cooling water source. Connect the collection bottle to the outlet of the condenser and confirm the sealing again. Parameter setting: Set appropriate operating temperature and pressure based on the properties and boiling point differences of the mixture to be separated. Ensure that the temperature control equipment for the distillation flask and condenser is functioning properly and set the required temperature. Start operation: Open the cooling water source to ensure that the condenser can effectively cool the steam. Start heating the distillation flask to allow the mixture to evaporate. Monitor temperature, pressure, and rate of product collection, and adjust as needed. Collection and monitoring: The separated product will condense into liquid in the condenser and drip into the collection bottle. Collect through the outlet of the collection bottle and continuously monitor and adjust the operating parameters. Maintenance Guide Cleaning and Disinfection: After use, promptly clean the internal residues to prevent material solidification and blockage of pipelines. Regularly use appropriate cleaning agents and disinfectants to clean and disinfect equipment. Inspection and replacement: Regularly inspect various components of the equipment, such as seals, sensors, and pipeline connections, to ensure that there is no damage or aging. Regularly inspect and replace consumable components such as filters, seals, etc. Storage environment: Store in a dry, clean, and well ventilated environment to avoid moisture and pollution. Following the above operation and maintenance guidelines can ensure the efficient and stable operation of the short-range molecular distillation device.
