Claims
- 1. A splash bar apparatus comprising:at least a plurality of spaced apart splash bars arranged generally vertically and parallel with one another for contact heat and mass transfer between liquid and gas with the liquid directed substantially vertically downward over and through said plurality of bars, each of said splash bars including both flat and curvilinear surfaces all of which are substantially perforated with holes, both said flat and curvilinear perforated surfaces providing substantial projected splash surfaces from the vertical for falling liquid droplets and which redirect those droplets and generate new droplets by impact and mechanical dispersion to similar surfaces on adjacent splash bars, each of said bars has a cross section that includes near the upper end a short first curvilinear portion which extends laterally toward one adjacent bar and meets one end of an extended first straight portion the other end of which meets with a short second curvilinear portion which extends toward the vertical downward direction.
- 2. The apparatus of claim 1 including means for mounting said bars adjacent said first and second curvilinear portions into a grid.
- 3. The apparatus of claim 2 wherein said mounting means includes hook portions as part of the cross section of said bars at the top of said first curvilinear portion and at the bottom of said second curvilinear portion.
- 4. The apparatus of claim 1 wherein said first straight portion of said bar cross section makes an angle of no more than substantially 45° with the vertical.
- 5. The apparatus of claim 2 including a plurality of said grids positioned vertically spaced apart from one another and wherein the lateral extension of the splash bars in adjacent grids are in opposite directions.
- 6. The apparatus of claim 5 including said plurality of said grids positioned in a counter current, induced draft cooling tower directly below a liquid spray system.
- 7. The apparatus of claim 6 including at least one of said grids in the transitional flow gas intake portion of said cooling tower.
- 8. The apparatus of claim 1 wherein said splash bar cross section includes a short third curvilinear portion extending from the bottom of said second curvilinear portion and with a reverse incline away from said one adjacent bar and meets with one end of a second straight portion shorter than the first straight portion, the other end of said second straight portion meeting with a fourth curvilinear portion which extends toward the vertical downward direction.
- 9. The apparatus of claim 8 including means for mounting said bars adjacent said first and fourth curvilinear portions into a grid.
- 10. The apparatus of claim 9 wherein said mounting means includes hook portions as part of the cross section of said bars at the top of said first curvilinear portion and at the bottom of said fourth curvilinear portion.
- 11. The apparatus of claim 8 wherein said first and second straight portions of said bar cross section make an angle of no more than substantially 45° with the vertical.
- 12. The apparatus of claim 8 including means for mounting said bars adjacent said first and fourth curvilinear portions into a grid.
- 13. The apparatus of claim 12 wherein said mounting means includes hook portions as part of the cross section of said bars at the top of said first curvilinear portion and at the bottom of said fourth curvilinear portion.
- 14. The apparatus of claim 8 wherein said first straight portion of said bar cross section makes an angle of no more than substantially 45° with the vertical.
- 15. The apparatus of claim 12 including a plurality of said grids positioned vertically spaced apart from one another and wherein the lateral extension of the splash bars in adjacent grids are in opposite directions.
- 16. The apparatus of claim 15 including said plurality of said grids positioned in a counter current, induced draft cooling tower directly below a liquid spray system.
- 17. The apparatus of claim 16 including at least one of said grids in the transitional flow gas intake portion of said cooling tower.
- 18. The method of transferring heat between a gas and a liquid through a grid of splash bars by flowing the liquid in droplet form down through the grid of splash bars and the gas up through the grid of splash bars, creating droplets of liquids by bouncing droplets off the bars, flowing the liquid across the bars to perforations and shearing and dispensing new droplets off the bars at the perforations, directing the flow of liquid on a curvilinear surface lateral of one bar toward another bar, then over one extended flat surface and then over another curvilinear surface toward the vertical downward direction.
- 19. The method of claim 18 including directing the flow of liquid from said other curvilinear surface in a reverse incline over a third curvilinear surface then over another flat surface and finally over a fourth curvilinear surface and toward the vertical downward direction.
