The utility model relates to a boiler and steam turbine arrange waste water recovery device of recycling surely, including arrange the reservoir jar surely, condensation waste water recovery water tank, deareator, denitration urea dissolving tank, arrange the reservoir jar surely and have gas vent and drain trap, arrange the gas vent of reservoir jar surely and gas-water separator's steam inlet tube coupling, arrange the drain trap and the condensation waste water recovery water tank tube coupling of reservoir jar surely, deareator's drain trap also with condensation waste water recovery water tank tube coupling simultaneously, condensation waste water recovery water tank with denitration urea dissolving tank tube coupling and be provided with hydrophobic pump and valve on the pipeline. The boiler and steam turbine fixed-discharge waste water recycling device is used for recycling waste heat and waste water resources of the boiler and the steam turbine fixed-discharge of a thermal power plant, waste of water resources and heat energy is reduced, pollution emission of condensate water is reduced, and production cost of enterprises is saved.
Description
Technical Field
The utility model belongs to the technical field of thermoelectric system energy saving and emission reduction technique and specifically relates to a boiler and steam turbine surely arrange waste water recovery and recycle device is related to.
Background
Thermal power plant needs regularly to carry out blowdown to the main steam of boiler and steam turbine system and handle in order to guarantee that steam is qualified, steam conduit needs the drainage of periodic discharge, prevent hydrophobic accumulation, the high-pressure superheated steam strikes the phenomenon that ponding caused the water hammer, arouse the vibration of pipeline and equipment, cause the harm to equipment, superheated steam in the steam conduit also can cool off into the comdenstion water at last, usually, these comdenstion waters salinity is higher, and contain a certain amount of suspended solid and biological colloid, direct emission can cause thermal waste, the waste and the environmental pollution of water resource, the safe emission must pass through the processing of multichannel process, the cost of enterprises has been improved again so.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the boiler and steam turbine fixed-discharge waste water recycling device is provided to recycle waste heat and waste water resources of the boiler and the steam turbine fixed-discharge of a thermal power plant, reduce pollution discharge and save production cost of enterprises.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a boiler and steam turbine surely arrange waste water recovery device of recycling, including surely arranging reservoir jar, condensation waste water recovery water tank, deareator, denitration urea dissolving tank, surely arrange reservoir jar and have gas vent and drain, surely arrange the gas vent of reservoir jar and deareator's steam inlet tube coupling, surely arrange the drain and the condensation waste water recovery water tank tube coupling of reservoir jar, deareator's drain also with condensation waste water recovery water tank tube coupling simultaneously, condensation waste water recovery water tank with denitration urea dissolving tank tube coupling and be provided with drain pump and valve on the pipeline.
The device operation mode: the constant-discharge steam of the boiler and the steam turbine enters the constant-discharge reservoir tank 1 through respective sewage discharge pipelines, wherein condensed water can be directly discharged to the condensed wastewater recovery water tank 2 through a drain port of the constant-discharge reservoir tank 1, steam is discharged to the gas-water separator 3 through an exhaust port of the constant-discharge reservoir tank 1, the condensed water generated after being treated by the gas-water separator 3 also flows back to the condensed wastewater recovery water tank 2 through the drain port of the gas-water separator 3, the condensed water collected by the condensed wastewater recovery water tank 2 is pumped to the denitration urea dissolving tank 4 through the drain pump 5 for dissolving urea for denitration, and the temperature of the condensed water completely meets the temperature requirement (about 60 ℃) required by the denitration urea dissolving water.
The utility model has the advantages that: the boiler and steam turbine fixed-discharge waste water recycling device is used for recycling waste heat and waste water resources of the boiler and the steam turbine fixed-discharge of a thermal power plant, waste of water resources and heat energy is reduced, pollution emission of condensate water is reduced, and production cost of enterprises is saved.
