A NOVEL APPARATUS AND A METHOD FOR SCRAPPING AND REMOVING SOOT DURING DEPOSITION IN A MCVD PROCESS

摘要

This invention is related generally to the field of manufacturing of optical fiber preform and more particularly to removal of soot from the exhaust tube during a MCVD process. The current methods of soot removal are ineffective in terms of ensuring the quality required of the final performs. The present invention provides a novel apparatus and a method to scrape the excess soot deposited inside the exhaust tubes that are used in the MCVD processes deployed in optical fiber manufacturing. The present invention aimed at effectively scrapping and removing the soot deposited inside wall of exhaust tube during the deposition process and to ensure proper flow of reactant gases inside the deposition tube and also through the exhaust tube further to the collection box. The method ensures the safety of the process equipment and the materials used therein, and also help maintain the quality of the final product. The invention comprises a soot remover rod as the inventive apparatus and a method of using the same.
