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

Abstract

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. The floating ball type self-balance dewatering device has such characteristics and beneficial effects as simple structure, few mechanical moving parts, rigidity, durability, prevention of the steam leakage, prevention of the heat loss, prevention of the environmental pollution, low working environment requirement and wide application range.

Description

technical field [0001] The invention relates to a floating ball type self-balancing hydrophobic device and a method for calculating the hydrophobic flow area thereof. The utility model relates to a drain device suitable for maintaining the water level of condensed water so as to maintain the balance of heating steam in and out, and belongs to the technical field of steam heating equipment in electric power systems. Background technique [0002] The drain system is an important system in the steam heating process. A well-performed drain system can ensure that only condensed water is discharged to prevent high-grade steam leakage loss. The drain system can also be used to maintain the condensed water level to maintain the balance of heating steam in and out. [0003] At present, there are mainly mechanical, thermodynamic, thermostatic, gas-liquid two-phase balance systems, power delivery systems and water level control valves for hydrophobic balance. details as follows: [0...
