Anti-pollution and anti-germ system
First Claim
1. An apparatus for the purification of polluted gases emitted by a polluted gas emitting source connected by a first duct to a chimney having a top outlet, comprising in combination with said first duct and chimney, a fume collector mounted on top of said chimney and having an inlet facing and spaced from said chimney outlet, a gas circulating turbine having an inlet, a second duct connected to said turbine inlet and to said collector, a gas purifiying means connected to the outlet of said turbine, and a by-pass duct by-passing said chimney and communicating said first duct upstream of said chimney and said second duct, said turbine having a gas circulating capacity for a predetermined polluted gas output of said source, sufficient to draw atmospheric air downwardly through said chimney from its top outlet and through said collector and second duct.

Abstract
A filter apparatus for use with smokestacks, comprising: a smoke collector mounted opposite and spaced from the chimney outlet to collect the smoke emitted from the chimney. A turbine draws the smoke from the collector and feeds it to a circuit where the smoke is first washed by water jets, then by steam jets then again by water jets and is then filtered in an electrostatic filter. If the gases contain living microorganisms, these are killed in a burner. If the gases are not clean enough, they can be recirculated. If the apparatus fails, the gases are safely discharged by the chimney.
