SECTIONAL COOLING TOWER Russian patent published in 2005 - IPC

FIELD: heat-power engineering.

SUBSTANCE: proposed sectional cooling tower includes tower with peripheral and inner circular sprinkling sections mounted inside it, water catcher located above these sections and sprinkler located under them. Lower portion of 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 running from periphery to axis of tower which are communicated in pairs by means of water spraying pipe lines. Water distributing system is provided with two circular water distributing pipe lines laid in pond. Supply pipe lines are located in pond and are connected to one of water distributing pipe lines each. Support pipe lines are connected to circular water distributing pipe lines by means of distributing pipe lines laid in pond. Support pipe lines connected to peripheral circular sprinkling section are connected to one of circular water distributing pipe line and support pipe lines connected to inner circular sprinkling section are connected to other circular water distributing pipe line. Inner diameter of pipe lines connected to inner circular sprinkling section is lesser than inner diameter of pipe lines connected to peripheral circular sprinkling section. 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 closing by air escaping from ports of cooling tower.

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