Smog eliminator

A device for eliminating carbon particulates from smoke using continuous, recirculating, pressure water sprays in a uniquely designed spray booth which is mounted on a smoke stack and means for cleaning the recirculating pressure water, which comprises:

• (a) a spray booth means comprising two conical sections joined at the bases thereof, the upper section being connected in a leak-proof way to the upper section of a smoke stack and the lower section being connected in a leak-proof way to the lower section of a smoke stack;
• (b) a conical deflector means, centrally mounted by a mounting means within said spray booth means, having an upwardly directed vertex and a base diameter greater than the diameter of the lower section of said smoke stack;
• (c) a spray means comprising a multiplicity of spray nozzels mounted around the inner circumference of the lower conical section of the spray booth means, adjacent to the juncture of the bases of the upper conical section and the lower conical section, and directed to spray above said conical deflector means within the upper conical section, whereby sprayed recirculating pressure water encounters rising smoke first as sprayed upward and second as deflected downward on striking the inside wall of the upper conical section of said spray booth;
• (d) a water collecting means comprising the lower section of the smoke stack being connected to the lower conical section in a leak-proof way such that the upper-most edge of said smoke stack section protrudes into the spray booth means to form an annular water collecting gutter;
• (e) a gravity drain means comprising a pipe mounted at the lowest edge of the lower conical section such that water in the water collecting means will drain through said pipe by gravity;
• (f) an open water tank partially filled with sand and divided into two compartments by a partial vertical wall, said vertical wall being mounted so as to prevent flow from one compartment to the other except at the base thereof along the bottom of the open water tank;
• (g) a recirculation pump;
• and
• (h) a pressurized recirculation water reservoir;
• whereby, smoke containing carbon particulates in the smoke stack rising into the spray booth means has particulates removed therefrom by entrainment in pressured water sprayed into the upper part of said spray booth means, the washed smoke thereafter rising into the upper section of the smoke stack while the pressurized water containing carbon particulates drops onto the conical deflector means and is deflected into the water collecting means, from which said water drains through the gravity drain means into the first compartment of the open water tank, passing through the sand filling and under the vertical wall into the second compartment of the open water tank by gravity, the majority of the carbon particulates being removed in the sand filling, being drawn into the recirculation pump, pumped into the pressurized recirculation water reservoir, and returned to the spray booth means through the spray means.
