Floating ball type self-balance dewatering device and dewatering circulation area calculating method thereof

The invention relates to a floating ball type self-balance dewatering device and a dewatering circulation area calculating method thereof. The floating ball type self-balance dewatering device comprises a shell, a floating ball, a drain pipe, a water inlet pipe structure and a gas balance pipe; the shell is arranged in a normal water level position higher than a heat exchanger in a dewatering system; a water outlet is formed in the bottom end of the shell; the floating ball is arranged in the water outlet; the top of the shell is communicated with an upper gas space position of the heat exchanger through the gas balance pipe; the shell is provided with a water inlet end and a drain end; the water inlet end of the shell is communicated with a water outlet end of the heat exchanger through the water inlet pipe structure to convey water of the heat exchanger into the shell; and the drain end of the shell is arranged on the bottom surface of the shell, and is communicated with the drain pipe.
