DEVICE FOR THE FILTRATION AND COLLECTION OF MICROPARTICLES IN A GASEOUS ENVIRONMENT

摘要

A device (10) for filtering and collecting microparticles comprises a casing for housing a central chamber (11) that communicates with a hopper (12) below and with a hood (13) above, and operating machines designed to suck in dusty air from the atmosphere and to deliver treated air. The central chamber (11) has at least one filter (27) designed to retain fine-grain particles and the hopper (12) comprises a station for filtering and tansferring medium-grain microparticles.
