Abstract
A clean-air filtration system has a main pipe with an entry for attaching to an exhaust source and an exit. The main pipe has a plurality of openings for dispersing water within the main pipe. A water source is connected to the main pipe and supplying water to the openings. A particulate interceptor is connected to the main pipe for removing particulates from an exhaust flow. A particulate storage unit is connected to the particulate interceptor.
Claims19
A clean-air filtration system, comprising:
- a flexible inlet tube for attaching to an exhaust gas source outputting an exhaust gas stream;
- a main pipe connected to said flexible inlet tube and conducting the exhaust gas stream;
- a filter system disposed downstream of said flexible inlet tube in said main pipe, said filter system having a filter for removing particulates from the exhaust gas stream;
- a water source conducting water to said main pipe;
- said main pipe having a section defining a water injection stage injecting water into the exhaust gas stream passing by, the water colliding with the exhaust gas stream entrapping the particulate and forming a gummy coagulant formed of the water and entrapped particulate, said main pipe in said water injection stage having a loop with a curve shape that bends around and crosses itself, said loop subjecting the gummy coagulant traversing said loop to centrifugal forces;
- and
- a particulate interceptor connected to said main pipe for receiving said gummy coagulant.

A method for cleaning an exhaust gas stream, which comprises the steps of:
- connecting a flexible inlet tube of a clean-air filtration system to an exhaust pipe transporting the exhaust gas stream;
- conducting a flow of the exhaust gas stream into a main pipe connected to the flexible inlet tube;
- conducting the exhaust gas stream past a filter system disposed downstream of the flexible inlet tube in the main pipe, the filter system having a filter for removing particulates from the exhaust gas stream;
- conducting the exhaust gas stream into a water injection stage of the main pipe where water is injected into the exhaust gas stream passing by, the water colliding with the exhaust gas stream entrapping particulates and water soluble gases thus forming a gummy coagulant formed of the water and entrapped particulates and gases, the water injection stage having a loop with a curved shape that bends around and crosses itself, the loop subjecting the gummy coagulant traversing the loop to centrifugal forces;
- and
- conducting the gummy coagulant into a particulate interceptor.
