Abstract
A spray tower (20) for improving contact between a gas stream (22) and a fluid (24). The spray tower (20) includes a tank (26) having an inlet (32) and an outlet (34), and a plurality of spray nozzles (28) positioned in the tank, each of the plurality of spray nozzles including a spray outlet (38). Each of the plurality of spray nozzles (28) is adapted to spray a cone (40) of the fluid (24) through the spray outlet (38) into the tank (26). The spray tower (20) also includes a perforated plate (30) having a plurality of perforations (44). The perforated plate (30) is positioned in the tank (26) so as to define a cross-section of the tank and each of the plurality of perforations (44) is aligned with the cone (40) flowing from the spray outlet (38) of one of the spray nozzles.
Claims9
A spray tower for improving contact between a gas stream and a fluid, said spray tower comprising:
- a tank including an inlet and an outlet, said gas stream flowing between said inlet and said outlet along a flow path and in a main direction;
- a plurality of spray nozzles positioned in said tank, each of said plurality of spray nozzles including a spray outlet, wherein each of said plurality of spray nozzles is adapted to spray a cone of said fluid through said spray outlet into said tank;
- and
- a perforated plate having a plurality of perforations, said perforations consisting of apertures in said perforated plate and not having any raised surfaces with respect to other portions of said perforated plate, wherein said perforated plate is positioned in said tank so as to define a cross-section of said tank and said perforated plate is positioned so that each of said plurality of perforations is downstream of and aligned with said cone flowing from said spray outlet of one of said plurality of spray nozzles, said perforated plate being positioned closer to said inlet than said spray outlets.
A perforated plate for improving contact between a gas stream and a fluid flowing in a spray tower, said spray tower including a tank and spray nozzles for distributing a cone of said fluid, said perforated plate comprising:
- a plate adapted to cover a cross-section of said spray tower, said plate having a plurality of perforations, said perforations consisting of apertures in said plate and not having any raised surfaces with respect to other portions of said plate, wherein each of said plurality of perforations is configured to be aligned with said cone flowing from one of said spray nozzles, said perforated plate being positioned closer to an inlet in said spray tower for said gas stream than said spray nozzles.
A method of improving contact between a gas stream and a fluid, said method comprising:
- directing said gas stream into a tank via an inlet;
- positioning a plurality of spray nozzles in said tank, each of said plurality of spray nozzles including a spray outlet, wherein each of said plurality of spray nozzles is adapted to spray a cone of said fluid through said spray outlet into said tank;
- positioning a perforated plate having a plurality of perforations in said tank so that each of said plurality of perforations is downstream of and aligned with said cone flowing from said spray outlet of one of said plurality of spray nozzles, said plurality of perforations consisting of apertures in said perforated plate and not having any raised surfaces with respect to other portions of said perforated plate, said perforated plate being positioned closer to said inlet than said spray outlets;
- and
- spraying said fluid through said plurality of spray nozzles and into said tank.
