Abstract
An exposure chamber includes an imperforate casing having a fluid inlet at the top and an outlet at the bottom. A single vertical series of imperforate trays is provided. Each tray is spaced on all sides from the chamber walls. Baffles adjacent some of the trays restrict and direct the flow to give partial flow back and forth across the chambers and downward flow past the lowermost pan adjacent a central plane of the chamber.
Claims7
A fluid treatment chamber comprising:
- a. imperforate substantially vertical front, rear, and side walls and closed upper and lower ends;
- b. a fluid inlet in one of said ends;
- c. a fluid outlet in the other of said ends;
- d. an inlet deflector adjacent said inlet constructed and arranged to deflect fluid introduced at said inlet towards said substantially vertical walls;
- e. a plurality of imperforate substantially horizontal pans within said chamber, each of said pans, other than that most remote from said inlet, being spaced from said vertical walls by distances which are sufficient to permit flow of fluid along said walls sufficient to supply fluid to pans downstream of it;
- but which are small compared to the horizontal dimensions of said pans, said pans otherwise occupying the entire cross sectional area of said chamber;
- f. means constructed and arranged to prevent substantial flow of fluid between said vertical walls and said pan most remote from said inlet except for an area adjacent a center-plane of said chamber, said means being constructed and arranged to provide open spaces on opposite sides of said pan, said spaces having materially different areas.
