Vacuum cleaning furnace is also called vacuum calciner. There are three kinds of common vacuum cleaning furnace: horizontal type, well type and vertical type, which are widely used in chemical fiber industry. It makes use of the characteristics that polymer can be melted at about 300 degrees, air can be cracked and haggard when it is higher than 300 degrees, and can be completely oxidized when it is higher than 400 degrees in the environment with a small amount of air and a certain degree of vacuum. Firstly, the workpiece with polymer dirt is heated to 300 degrees (according to the process requirements), so that a large number of polymer on the workpiece will melt and flow to the lower part of the furnace The temperature of the furnace is then raised to 400-500 ℃, and the vacuum pump is opened at the same time. A small amount of fresh air is introduced to fully oxidize the remaining polymer. The generated carbon dioxide is pumped by the water ring vacuum pump after being sprayed by water and discharged out of the furnace together with water.
