Description

Power plant boiler sewer waste heat recycling system
Technical field
The present invention relates to a kind of sewer waste heat recycling system, especially power plant boiler sewer waste heat recycling system, Belong to heat recovery technical field.
Background technology
Thermal power plant is in order to ensure the quality of stove water and steam, time properly functioning, needs part salinity concentration of continuously draining Higher stove water, referred to as sewer.Conventional system is to drain from drum and water-cooling wall lower collecting box to need the stove water of removing, through continuously Blowdown system expander, steam is recovered to oxygen-eliminating device recycling due to quality better, and unevaporated sewer is to periodical blowdown Flash vessel, continues dilatation, and the steam produced after dilatation drains into air, and the water that unevaporated salinity concentration is higher delivers to sewer In cooling tank, discharge after drawing cold water cooling.The sewer temperature of continuous blowdown flash tank outlet is about 180 DEG C, and enthalpy is 754kJ/kg.According to environmental requirement, sewer temperature must be down to less than 40 DEG C and just be allowed discharge, draws cold water temperature-fall period and causes The waste of heat energy and water resource.The demineralized water make-up water mode of conventional thermal power plant is that the demineralized water of 20 DEG C directly fills into steamer simultaneously Machine condenser, heats through steam and is supplied to boiler after deoxygenation in oxygen-eliminating device, and the process of heating needs certain energy consumption, enterprise Operating cost increase, environment has been destroyed simultaneously.
Summary of the invention
It is an object of the invention to, it is provided that a kind of power plant boiler sewer waste heat recycling system, by this system to boiler The heat of sewer reclaims, the demineralized water make-up water of heating thermal power plant, reduces the gross coal consumption rate of power plant, saves cooling simultaneously Water.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that:
This system includes continuous blowdown flash tank, regular unloading container, turbine condenser, oxygen-eliminating device and water water-to-water heat exchanger. Wherein continuous blowdown flash tank is communicated in regular unloading container through blowdown water regulating valve group, at continuous blowdown flash tank and sewer Bypass duct is set up, i.e. sewer bypass inlet pipeline and sewer bypass outlet pipeline between regulation valve group.Demineralized water moisturizing warp The benefit water regulating valve group moisturizing of effusion meter, demineralized water is mended to turbine condenser, effusion meter and demineralized water and is provided with between water regulating valve group Demineralized water moisturizing bypass inlet pipeline.The side of water water-to-water heat exchanger and sewer bypass inlet pipeline and sewer bypass outlet pipeline Connection, opposite side and demineralized water moisturizing bypass inlet pipeline and demineralized water moisturizing bypass outlet pipeline communication.Sewer bypass outlet Pipeline is communicated in regular unloading container through blowdown water regulating valve group, and demineralized water moisturizing bypass outlet pipeline communication is in oxygen-eliminating device.
Water water-to-water heat exchanger in aforementioned system is shell-and-tube heat exchanger, is mainly made up of with housing heating surface bank.Heating surface bank one end Bypassing inlet pipeline by sewer inlet communication sewer, the other end passes through sewer outlet sewer bypass outlet pipeline; Housing side bypasses inlet pipeline by demineralized water inlet communication demineralized water moisturizing, and opposite side passes through demineralized water outlet demineralized water Moisturizing bypass outlet pipeline.Sewer enters heating surface bank through sewer bypass inlet pipeline, according to heat convection principle, passes through Tube wall transmission heat, this heat will flow into the demineralized water moisturizing heating of housing, and the demineralized water moisturizing after intensification is through demineralized water outlet stream Enter demineralized water moisturizing bypass outlet pipeline, then flow into oxygen-eliminating device.
Water water-to-water heat exchanger in aforementioned system can also be plate type heat exchanger, is made up of a series of metal sheet closed assemblies, two panels plate Between form the narrow and small and passage of complications, cold fluid and hot fluid respectively flows through passage, middle is separated by cold fluid and hot fluid by plate, and leads to Cross plate heat transfer.High temperature runner one end bypasses inlet pipeline by sewer inlet communication sewer, and the other end is gone out by sewer Mouth connection sewer bypass outlet pipeline;Low temperature runner side bypasses inlet pipeline by demineralized water inlet communication demineralized water moisturizing, Opposite side passes through demineralized water outlet demineralized water moisturizing bypass outlet pipeline.
The motility overhauled for convenience and run, this system is also provided with main road shut-off valve and bypass shut-off valve.Continuous blowdown expands It is provided with main road shut-off valve between container and blowdown water regulating valve group, between effusion meter and demineralized water benefit water regulating valve group, also is provided with main road Shut-off valve;The sewer bypass inlet pipeline of water water-to-water heat exchanger side is respectively equipped with bypass shutoff on sewer bypass outlet pipeline Valve, the demineralized water moisturizing bypass outlet pipeline of opposite side is also respectively equipped with bypass shut-off valve on demineralized water moisturizing bypass inlet pipeline. When water water-to-water heat exchanger runs, close the master between the blowdown water regulating valve group before continuous blowdown flash tank and regular unloading container Road shut-off valve, is also switched off effusion meter and demineralized water mends the main road shut-off valve between water regulating valve group, opens sewer bypass inlet tube Bypass shut-off valve on road and sewer bypass outlet pipeline, opens demineralized water moisturizing bypass inlet pipeline and demineralized water moisturizing simultaneously Bypass shut-off valve on bypass outlet pipeline, the sewer of continuous blowdown flash tank flows through water water-to-water heat exchanger release heat, demineralized water Moisturizing flows through water water-to-water heat exchanger and absorbs heat, has reclaimed the waste heat of boiler blowdown water;When water water-to-water heat exchanger needs to stop transport, reversely Operate above valve.
Compared with prior art, it is an advantage of the current invention that:
This system makes full use of the demineralized water make-up water of the heat thermal power plant of boiler blowdown water, improves the temperature of make-up water, Thus reduce the gross coal consumption rate about 0.26-0.52g/kWh of power plant.While sewer heats up to demineralized water make-up water, also reduce Own temperature, reduces during discharge and is even no longer necessary to draw cold water cooling.These behaves are very effectively saved the energy, are reduced energy consumption, Reduce the operating cost of enterprise, improve the economic benefit of unit, preferably protect water source and environment.
