Air washer

Claim 2

In an air washer, a descending water pipe having a nozzle at its lower end, deflector means spaced downwardly from said nozzle for creating outwardly moving droplets of water, an air space below said deflector, means spaced above said air washer for drawing air into said space and upwardly through said droplets, a relatively narrow annular passage extending upwardly beyond said droplets, said passage being formed by a cylindrical member mounted on and spaced radially outwardly from said water pipe and a first annular wall spaced outwardly from and surrounding said last-mentioned member, an annular catch basin surrounding said passage including a second annular wall spaced outwardly from said first annular wall, a knockout baffle plate mounted a relatively short distance above the top of said narrow passage whereby the high velocity air passing upwardly through the passage will strike said knockout baffle and be deflected thereby, the diameter of said knockout baffle being considerably greater than that of the annular wall which forms the outside of said narrow passage so that water droplets and foreign particles entrained in the air will drop into said catch basin, and means for draining water and foreign particles from the catch basin.

Claim 3

The combination according to claim 1, further provided with a frustoconical wall leading from said air space to the bottom of said annular wall forming the outside of the passage, said drain means comprising a downspout in said frustoconical wall.

Claim 4

The combination according to claim 1, said member having a main portion of cylindrical shape, and means for vertically adjusting the position of said member on said water pipe.

Claim 5

The combination according to claim 1, said deflector being dish shaped, and means for supporting said deflector comprising a plurality of circumferentially spaced arms secured to said nozzle.

Claim 6

The combination according to claim 4, further proviDed with a frustoconical wall extending outwardly from the bottom of said annular passage and forming the bottom of said catch basin.

Claim 7

The combination according to claim 1, said baffle being of relatively flat circular shape, a cylindrical member secured to the underside of said baffle and forming part thereof, and means for adjustably securing said baffle to said water pipe.

Claim 8

The combination according to claim 1, said cylindrical member being removably mounted on said water pipe and replaceable by similar members of different diameters whereby the cross sectional area of said passage may be varied.

Claim 9

The combination according to claim 7, said nozzle being threaded onto the bottom of said water pipe, said cylindrical member having frustoconical ends engaging the water pipe, whereby the cylindrical member may be replaced by unscrewing the nozzle and slipping off the cylindrical member.

Claim 10

In an air washing apparatus, a collection trough having water therein, an eliminator mounted on and extending upwardly from said trough, an air washer mounted in the bottom of said eliminator, means surrounding said eliminator for drawing air into said collection trough, upwardly through said air washer and through said eliminator, the air washer comprising a water pipe extending downwardly from said eliminator, a nozzle at the bottom of said water pipe, a deflector supported below said nozzle for creating a spray of outwardly moving water particles, means leading air from said collection trough upwardly through said water particles, a relatively narrow annular flow passage extending above said water particles, said passage being formed by an annular enlargement mounted on and extending radially outwardly from said water pipe and an annular wall outwardly of and surrounding said enlargement and spaced a substantial distance inwardly from the sides of said eliminator, a knockout baffle mounted a relatively short distance above the top of said narrow passage and having an outer diameter substantially greater than said passage, an annular catch basin outwardly of and surrounding said narrow flow passage and below the outer portions of said knockout baffle, and a downspout leading from the bottom of said catch basin to said collection trough.

Claim 11

In an air washing apparatus, a collection trough having water therein, an eliminator mounted on and extending upwardly from said trough, an air washer mounted in the bottom of said eliminator, means surrounding said eliminator for drawing air into said collection trough, upwardly through said air washer and through said eliminator, the air washer comprising a water pipe extending downwardly from said eliminator, a nozzle at the bottom of said water pipe, a deflector supported below said nozzle for creating a spray of outwardly moving water particles, means leading air from said collection trough upwardly through said water particles, a relatively narrow annular flow passage extending above said water particles, said passage being formed by an annular enlargement mounted on and extending radially outwardly from said water pipe and an annular wall outwardly of and surrounding said enlargement and spaced a substantial distance inwardly from the sides of said eliminator, a knockout baffle mounted a relatively short distance above the top of said narrow passage and having an outer diameter substantially greater than said passage, an annular catch basin outwardly of and surrounding said narrow flow passage and below the outer portions of said knockout baffle, and a downspout leading from the bottom of said catch basin to said collection trough.

Claim 12

The combination according to claim 9, further provided with means for vertically adjusting the position of said enlargement on said water pipe, said baffle being also mounted for vertical adjustment on the water pipe.

Claim 13

The combination according to claim 9, further provided with a frustoconical wall extending outwardly from the bottom of said narrow passage and forming the bottom of said catch basin.

Claim 14

The combination according to claim 9, said enlargement being removably mounted on said water pipe whereby it may be replaced with enlargements of different diameters.

Claim 15

The combination according to claim 9, further provided with a collar removably mounted on said enlargement.
