The invention discloses a lower-position water tank integrated closed
cooling tower. The lower-position water tank integrated closed
cooling tower comprises a
cooling tower shell, a first spraying plate
pipe, an
air pump, a dustproof net, a fan, a cleaning roller, a mounting port, a second spraying
pipe, a water outlet, a condenser, a first water conveying
pipe, a water pump, a water inlet, a
cooling coil, a bracket, a water collecting port, a water tank, a motor, a power frame, a slide block, a lead screw, a second water conveying pipe and an intake grid. The lower-position water tank integrated closed cooling
tower can spray and cool the
cooling coil through the second spraying pipe, the first water conveying pipe and the water pump; the
air pump can timely absorb
water vapor for coolingthrough the condenser; then, the
water vapor is conveyed to the first spraying plate pipe for spraying by the second water conveying pipe, so that the
cooling effect can be improved, and the influence on the fan by the
water vapor can be prevented; the dustproof net can achieve a dustproof effect to prevent dust from falling into the cooling
tower shell from the mounting port; and the motor, thepower frame, the slide block and the lead screw can control the cleaning roller to move back and forth to clean the dustproof net.
