Can paint removal uses the carbonization process of a continuous carbonization furnace

What process is better for baking paint on cans, such as chemical paint removal process, mechanical friction paint removal process, pyrolysis carbonization paint removal process, etc. Today, Henan Beigong will introduce it to you.

The disadvantage of the chemical paint removal process is that it produces a lot of wastewater and other pollutants, and is relatively poor in terms of environmental protection. The disadvantage of mechanical friction paint removal is that the paint removal is not complete. In recent years, the carbonization process of a continuous carbonization furnace has been used to remove paint from cans. Gradually it was adopted by everyone.

So what is the process of carbonization and paint removal from cans?

It crushes the waste cans. Generally, the waste cans are packed and compressed together. They are broken into small pieces and then continuously fed through the feeding system of the continuous carbonization furnace.

The continuous carbonization furnace has continuous feeding and continuous discharging. Some sealing devices at the feeding port and the discharging port ensure an oxygen-free or oxygen-poor environment in the carbonizing furnace. After the waste cans enter the carbonization furnace, the paint layer of the cans is pyrolyzed and carbonized at a temperature of about 500°C. As the main furnace of the carbonization furnace rotates, the paint layer falls off due to the self-motion of the rotation process. This process equipment has good heat transfer effect and is processed The quantity is large, no secondary pollution is produced, and continuous large-scale production can be achieved.

The carbonized cans are cooled by discharging water and then discharged. The temperature is generally 30-40°C.
