SECTIONAL COOLING TOWER Russian patent published in 2005 - IPC

FIELD: heat-power engineering.

SUBSTANCE: proposed sectional cooling tower includes peripheral and inner circular sprinkling sections, water catcher located above these sections and sprinkler located under them. Lower portion of cooling tower is provided with air intake ports and pond. Sprinkling sections are connected to water distributing system consisting of two supply pipe lines and support pipe lines. Inner and peripheral sprinkling sections are formed by dispensing pipe lines laid in way from periphery to axis of tower and communicated in pairs by means of spraying pipe lines. Water distributing system is provided with water distributing riser located in central portion of tower and provided with vertical partition dividing it into two cavities for supply of peripheral and inner sprinkling sections. Supply pipe lines are located in pond and are connected to different cavities of water distributing riser. Support pipe lines are connected to water distributing riser by means of distributing pipe lines laid in pond and connected to respective cavities of water distributing riser in upper portion. Cross-sectional area of tower occupied by peripheral circular sprinkling section is 55 to 65% of total cross-sectional area of tower occupied by peripheral and inner circular sprinkling sections. Air intake ports are provided with swivel dampers mounted on vertical axles and stops for locking these dampers in closed position. Each damper is mounted for free turn and area of each damper is divided by vertical axis into two unequal parts for automatic opening by incoming air and hermetic closing by escaping air.

EFFECT: enhanced efficiency of distribution of water between sprinkling sections and cooling of water.
