Plastic-Rod-Screen-Fills for Use in Evaporative Water Cooling and Airborne Fumes Removal Apparatuses and Fabrication Thereof

Abstract

The present invention involves plastic-rod-screen-fills for use as fill media in any evaporative water cooling and airborne fumes removal apparatuses. The plastic-rod-screen-fill consists of top and bottom frames and several plastic rods suspending from between the top and bottom frames in the shape of a rectangular thin plate as a rod screen. The plastic rods are separated sufficiently apart from each other in one layer and parallel to the length of the rectangular plastic-rod-screen-fill. The plastic rods and top and bottom frames are in one structure. Plastic-rod-screen-fills are assembled by adjoining to each other to fabricate the plastic-rod-screen-fills pack and designed to be installed upright or slantly in the evaporative cooling apparatuses. The plastic-rod-screen-fills have high manufacturing and installation cost competition, compared with those of current film fills and string-screen-fills. The fabrication methods of plastic-rod-screen-fills and plastic-rod-screen fill packs are described in the present invention.

What is claimed is: 
     
         1 . A plastic-rod-screen-fills pack for use in any evaporative cooling apparatuses, comprising:
 a multiplicity of plastic-rod-screen-fills assembled in the shape of a rectangular column pack, whereof top and bottom sides are covered with perforated plate, wherein a plurality of said plastic rods being parallel to length of said plastic-rod-screen-fills pack are vertically suspending from said top and bottom perforated plates of said plastic-rod-screen-fills pack.   
     
     
         2 . A plastic-rod-screen-fill employed in said plastic-rod-screen-fills pack for use in any evaporative cooling apparatuses, comprising:
 top frames, bottom frames, and several plastic rods suspended from between said top and bottom frames, wherein said plastic rods are separated sufficiently apart from each other in one layer in the shape of a rectangular thin plate, and wherein side frames of said plastic-rod-screen-fill are attached or not attached on both side of said rectangular plastic-rod-screen-fill, and wherein said plastic rods, top frames, and bottom frames are in one structure with side frames or without side frames.   
     
     
         3 . A plastic-rod-screen-fills pack for use in any evaporative cooling apparatuses, comprising:
 several attachment tabs properly located on both side surfaces of said top and bottom frames of said plastic-rod-screen-fill, some of said attachment tabs properly locating on said plastic-rod-screen-fill frame for joining said plastic-rod-screen-fills, whereby said attachment tabs are joined by aligning said attachment tabs with and inserting into the counterpart attachment tabs of said plastic-rod-screen-fill to be joined by pressing, wherein said attachment tabs including male and female attachment tabs, said male attachment tabs positioning on right sides of top and bottom frame of said plastic-rod-screen-fill and said female attachment tabs on left sides of top and bottom of said plastic-rod-screen-fill;   several piling tabs properly located on both top surfaces of said top and bottom frames of said plastic-rod-screen-fill for piling a said plastic-rod-screen-fill pack on previous said plastic-rod-screen-fill pack, whereby said piling tabs are joined by aligning said piling tabs with and inserting into the counterpart piling tabs of said plastic-rod-screen-fill to be joined by pressing, wherein said piling tabs including male and female piling tabs, said male piling tabs positioning on top surfaces of top frame of said plastic-rod-screen-fill and said female attachment tabs on top surface of bottom frame of said plastic-rod-screen-fill.   
     
     
         4 . A plastic rod screen fill as in  claim 2 , wherein said top and bottom frames of said rectangular plastic-rod-fill are made to produce holes and round ends of plastic rods located and fixed on center of holes when two of said plastic-rod-screen-fills are joined together. 
     
     
         5 . Plastic rods as in  claim 2 , wherein spiral corrugated lines are made on the surface of said plastic rod with each line properly separated to increase a contacting time of water and air during flowing down of water along said spiral corrugated lines on said plastic rods. 
     
     
         6 . A plastic-rod-screen-fill as in  claim 2 , wherein top surfaces of said top and bottom frames of said plastic-rod-screen-fill are formed in rectangular or trapezoidal shape and perpendicular to the length of said plastic-rod-screen-fill to fit in cross current evaporative cooling apparatuses. 
     
     
         7 . A plastic-rod-screen-fill as in  claim 2 , wherein top surfaces of said top and bottom frames of said plastic-rod-screen-fill are formed in rectangular shape and slanted to the length of said plastic-rod-screen-fill to fit in counter current cooling apparatuses. 
     
     
         8 . A plastic-rod-screen-fills pack as in  claim 1  and  2 , wherein said rectangular column plastic-rod-screen-fills pack is fabricated with said rectangular plastic-rod-screen-fills, and wherein said trapezoidal column plastic-rod-screen-fills pack fabricated with said trapezoidal plastic-rod-screen-fills. 
     
     
         9 . A plastic-rod-screen-fills pack as in  claim 1  and  2 , wherein slanted rectangular column plastic-rod-screen-fills pack is fabricated with said slanted rectangular plastic-rod-screen-fills. 
     
     
         10 . A plastic-rod-screen-fills pack for use in said evaporative cooling apparatuses like cooling towers as in  claim 1  and  8 , wherein said plastic-rod-screen-fills packs are employed in cross current cooling tower, wherein said plastic-rod-screen-fills packs are employed in rectangular, square, pentagon, and hexagon cooling towers, wherein said rectangular cooling tower has two fill zones of said plastic-rod-screen-fills packs near to two entrances of cooling air, wherein said square cooling tower have said plastic-rod-screen-fills packs to be placed near to two side or four side wall entrance of cooling air, and wherein said plastic-rod-screen-fills packs are placed near to the entrances of cooling air at the entire outside walls of said pentagon and hexagon cooling towers. 
     
     
         11 . A plastic-rod-screen-fills pack for use in said evaporative cooling apparatuses like cooling towers as in  claim 1  and  9 , wherein said slanted plastic-rod-screen-fills packs are employed in counter current cooling tower, and wherein said slanted plastic-rod-screen-fills packs are installed in an arrangement of V-type or X-type fill media.
