Abstract

An anti-smog filtration system receives exhaust gases from a burning device and passes them through a chemical solution for separating the particulates into the solution. The remaining exhaust gases are recirculated for further separation of particulates into the solution and exhausted. The impregnated solution is passed through a mechanical filtration tank for removal of particulates therefrom and the remainder going to drain. For further reduction of solids from the exhaust gases, they are delivered into a second solution containing tank for placing more particulate into the solution, the remainder being exhausted to atmosphere. The impregnated solution is circulated through a mechanical filter and drain and at the same time, a replenishing solution is pumped into the tank.

Claims

1. An anti-smog filtration system for use with a burning device having an exhaust stack with outlet;

a first tank containing a chemical and water solution at a predetermined level and having a first chamber thereabove;

an exhaust conduit at one end connected to said stack outlet and at its other end having a delivery outlet projected into said tank adjacent the bottom thereof;

a suction blower interposed in said conduit;

a first manifold header in said tank connected to said delivery outlet;

a series of parallel spaced longitudinally perforated pipes joined to and projecting from said header and closed at their outer ends, for the uniform delivery of exhaust gases into and throughout the bottom area of said tank;

a gas recirculation pipe at one end projected through said tank wall and into said first chamber, and at its other end having a delivery outlet projected into said tank;

a suction blower interposed in said recirculation pipe;

a second manifold header in said tank adjacent and above the first manifold header and connected to the delivery outlet of said gas recirculation pipe;

a series of parallel spaced longitudinally perforated pipes joined to and projecting from said second manifold header and closed at their outer ends for uniform delivery of recirculated exhaust gases into and throughout the bottom area of said tank; and

exhaust transfer pipes on said tank communicating with said first chamber remote from said gas recirculation pipe for delivering exhaust gas therefrom;

a filtration tank spaced from said first tank and including a series of removable filters and having a drain;

a dirty fluid delivery pipe inletting at the bottom of said first tank and outletting in said filtration tank; and

a pump interposed in said latter pipe;

a fresh solution tank spaced from said first tank;

a delivery pipe between said solution tank and said first tank; and

a pump interposed in said latter delivery pipe for replenishing the solution in said first tank.

2. In the filtration system of claim 1, a series of cooling fins mounted on and around and along said exhaust conduit for cooling the gases flowing therethrough.

3. In the filtration system of claim 1, said solution being a lime water solution.

4. In the filtration system of claim 1, said tanks being of concrete and having a liner selected from the group consisting of stainless steel and plastic material.

5. In the filtration system of claim 1, said tank being of metal and said liner being selected from the group consisting of stainless steel and plastic material.

6. In the filtration system of claim 1, a second tank adjacent the first tank containing a chemical and water solution at a predetermined level and having a second chamber thereabove;

said exhaust transfer pipes connected to said second tank and outletting into said second chamber;

a second delivery conduit having an elongated gas intake communicating with said second chamber and having a delivery outlet projected into said second tank adjacent its bottom;

a suction blower interposed in said second delivery conduit;

a third manifold header in said second tank connected to said delivery outlet of said second delivery pipe;

a series of parallel spaced longitudinally perforated pipes connected to said third header and closed at their outer ends, for uniform distribution of gas into said second tank solution throughout its area;

an exhaust chamber in said second tank partitioned from said second chamber for communication with the fluid in said second tank, receiving gases rising in said second tank; and

a series of clear air outlet stacks on the second tank communicating with said exhaust chamber.

7. In the filtration system of claim 6, a second filtration tank spaced from said second tank and including a series of removable filters and a drain;

a dirty fluid delivery pipe inletting at the bottom of said second tank and outletting in said second filtration tank; and

a pump interposed in said second dirty fluid delivery pipe.

8. In the filtration system of claim 7, a second solution delivery pipe between said solution tank and said second tank;

and a pump interposed in said second solution delivery pipe for replenishing the solution in said second tank.

9. In the filtration system of claim 6, a series of air cooling fins on and along said exhaust transfer pipes.

10. In the filtration system of claim 6, said solution including an alkalae carbonate.

11. In the filtration system of claim 6, said solution including calcium carbonate and water.

12. In the filtration system of claim 6, said solution including acidic acid for treatment of exhaust gases from a cement production kiln.

13. In the filtration system of claim 6, and a solution cooling means upon the interior walls of said first and second tanks.
