The invention discloses a fuel gas-steam combined circulation unit dewatering recycling system. A drain flash tank, a dewatering receiving header, a water discharging mother pipe, a water draining pipeline, a temperature lowering water pipeline, a steam discharging pipeline, an overflow pipeline, a water discharging pipeline, a pollution discharging unit and a steam condenser are included; the drain flash tank is connected with the temperature lowering water pipeline, the steam discharging pipeline, the dewatering receiving header, the overflow pipeline and the water discharging mother pipe; the drain flash tank is connected with a hot well of the steam condenser through the water discharging mother pipe and a dewatering recycling pipe; the overflow pipeline is connected with the pollutiondischarging unit; the water discharging mother pipe is connected with the water draining pipeline which is connected with the pollution discharging unit; the dewatering receiving header is connectedwith a dewatering pipe; and the dewatering recycling pipe is connected with the water discharging pipeline which is connected to a sewage recycling treatment system. The fuel gas-steam combined circulation unit dewatering recycling system solves the problems of work medium waste, hot pollution and random discharging and random draining in the processes of starring and running of a fuel gas-steam combined circulation unit, resources are saved, the economical efficiency of a power plant is improved, and obvious environment-friendly social benefits are generated.
Description
technical field [0001] The invention relates to the field of hydrophobic recycling, in particular to a drainage recovery system for a gas-steam combined cycle unit. Background technique [0002] At present, the gas-steam combined cycle unit usually ignores the problem of drain recovery during the start-up and operation of the unit, and directly discharges the drain, which not only causes waste of working fluid and heat, but also seriously affects the economical operation of the power plant. Pollution" and waste of water resources affect environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a drainage recovery system for a gas-steam combined cycle unit. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A drainage recovery system for a gas-steam combined cycle unit, including a drainage expansion vessel, a drai...
