The vacuum cleaning furnace is suitable for the cleaning of components, spinnerets, filter elements, etc. used in the production of polyester, acrylic and polypropylene in the chemical fiber industry, as well as for cleaning in the plastic, cable, and textile industries. The vacuum cleaning furnace uses polymer polymerization to melt at about 300℃, cracking and coking can be caused by isolating air above 300℃, and it can be completely oxidized in an environment with a small amount of air and a certain degree of vacuum above 400℃. The workpiece with polymer dirt is heated to 300°C (based on the process requirements), so that a large amount of polymer on the workpiece melts and flows into the collection container at the lower part of the furnace, and then the furnace temperature is raised to 400- At 500℃, turn on the vacuum pump at the same time and pass in a small amount of fresh air to fully oxidize the remaining polymer. The generated carbon dioxide will be pumped by a water ring vacuum pump after spraying with water and discharged out of the furnace together with water.
