Restoring Cooling Tower Outlet Fog into Water Cycle

摘要

The invented system used in wet cooling tower, restore outlet fog of cooling tower into collection basin and consequently cooling water cycle. This invention consists of three main components; pump and its pertaining piping, waterfall and micron fog eliminator. In the first stage, the air containing fog is passed through a waterfall before exhausting. This action causes some portions of fog to condensate and fall down, remaining droplets of the fog grow and together with air cross the fog eliminator blades. Fog's droplets are entrapped between blades, leave the air, and restore to the tower. Therefore, humidity of exhausted air from tower will be effectively reduced.

主权项

1- A counter flow wet cooling tower system for cooling warm water comprising; a pump; a waterfall header; a micron fog eliminator; blocking wall, a main collection basin, a first basin; a hose; fills packing; a suction fan; multiple nozzles; wherein said micron fog eliminator comprises multiple blades having specific thickness; wherein said blades absorb water droplets at least 10 microns and higher; wherein said blades are positioned perpendicular with respect to said first basin; said system further comprising a warm water inlet and a cooled pressurized water outlet; wherein said pressurized water outlet transfers cooled water accumulated inside said major basin to said waterfall header; wherein said cooled water falls from said waterfall header forming a waterfall effect against a waterfall wall; wherein said waterfall wall is adjacent to said first basin; wherein said hose connects said first basin and said main basin and transfers said cooled water inside said first basin to said main basin; therefore creating a water cycle inside said tower; wherein warm water enters said tower by said warm water inlet, then said warm water is sprayed directly on said fill packing via said multiple nozzles; wherein said fill packing is in direct contact with cold/ambient air that flows freely through said fills and due to a great temperature difference between said ambient air and said warm water, a portion of said warm water evaporates as a first discharged air-containing fog (first fog) and travels up and above said multiple nozzles to a higher section of said tower where said waterfall and wall block are located at, and wherein a remaining portion of said warm water loses its heat and is accumulated inside said main basin as said cooled water, wherein said first fog travels up towards said warm water and said multiple nozzles and by directly being in contact with said warm water its temperature and humidity increases forming a second discharged air-containing air fog (second fog) which has a higher temperature and higher humidity content in comparison to said first fog and said warm water; and therefore said second fog travels above said multiple nozzles and reaches said waterfall and wall block.
