What's the electric pyrolysis cleaning furnace?

Vacuum Cleaning Furnace is suitable for cleaning the polymer materials filters and strainers, making them be reused after calcination, and saving the production cost. It is also a kind of environmental protection equipment. The Vacuum Spinneret Cleaning Furnace applied the characteristics that polymer can be melted at a certain temperature, decomposed under the condiction of high temperature around 300℃ and isolating from air, and complete oxidation when above 400℃ and a little oxygen and certain vacuum degree. Using this characteristics, we first heat the cleaned pieces to the melting temperature, meiting the high polymer on the surface of filters and let them flow down into the waste collecting tank. At this time, surface of the filters remians only a little high polymer and ash content, when the furnace temperature rose up to the cracking temperature ( can according to technological requirements ), open the vacuum pump, lead to a small amount of air to the rest of high polymers, they will be completely oxidation and can get carbon dioxide and water, through the suction of water-ring vacuum pump, the carbon dioxide and water vapour generated in furnace are washed by the spray washer, and then discharged out the furnace. No exhaust gases, smog and ash throughout the working process, just a small number of carbon dioxide, and no more burning is needsd for the exhaust, the water takes away only a small amount of ash.

How does the electric pyrolysis cleaning furnace work?

I. Melting Phase.

The parts to be cleaned are heated to 320°C in the chamber. After this process, most of the polymer melts and drains into the bottom collector.

II. Pyrolysis Phase.

Polymer that did not melt during the first phase will be pyrolyzed and vaporized under vacuum. The generated gases are converted to CO2 and H2O (Vapor) in the catalyst heater.

III. Oxidation Phase.

Remaining polymer that still exist after the pyrolysis phase will be burnt under vacuum and limited air. The generated gases also are converted in the catalyst.
