Description
Technical field
The utility model relates to a kind of condensed steam feed water system of boiler, and this system is used to provide the cooling medium of condensing steam boiler afterbody condensing heat exchanger.Belong to condensing heat-exchange technology and boiler room system design field.
Background technology
Condenser boiler is because its high-efficiency environment friendly performance, obtained the recommendation of national energy-saving and emission-reduction relevant departments and the favor of numerous boiler applying unit.The core technology of condenser boiler is to increase condenser at boiler tail.According to the condensation heat transfer principle, the heat transferring medium that adopts temperature to be lower than the flue gas water dew point just can reach the purpose that flue gas condensing conducts heat.
Overwhelming majority Industrial Boiler all adopts thermal de-aeration, be 104 ℃ by the boiler feed temperature after the deoxygenation this moment, for traditional steam boiler, the afterbody economizer generally is reduced to exhaust gas temperature about 160 ℃, this moment, flue gas and boiler feedwater also had the bigger temperature difference, more easily arranged the economizer heat-transfer surface.If but to realize that condensing heat-exchange reclaims sensible heat and the latent heat in the flue gas, and according to flue gas characteristic, need this moment flue-gas temperature is reduced to promptly about 60 ℃ of flue gas steam dew-point temperatures, therefore must adopt to be lower than 60 ℃ cooling medium.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of flue-gas temperature is reduced to the condensed steam feed water system of boiler of flue gas steam dew-point temperature, is used to have the condensing heat-exchange of afterbody condenser of the steam boiler of thermal de-aeration.
The purpose of this utility model is achieved in that a kind of condensed steam feed water system of boiler, comprise steam boiler, softened water tank and thermal deaerator, the steam boiler afterbody is provided with economizer, also be provided with condenser at described steam boiler afterbody, the flue gas that goes out economizer inserts condenser, be provided with a vertical clapboard in the described softened water tank, vertical clapboard is separated into cold water side and hot water side with softened water tank, the cold water side water inlet links to each other with water softener, the cold water side delivery port links to each other with the condenser water inlet by the condensation cycle pump, the condenser delivery port inserts described hot water side, and the hot water side delivery port inserts thermal deaerator by the deoxygenation water pump, and the thermal deaerator water outlet inserts steam boiler.
The utility model is used for the flue gas heat of condenser waste heat recovery the moisturizing (oxygen-eliminating device is that the Steam Heating of utilizing boiler to produce feeds water, and heat circulates) of heating steam boiler between boiler and oxygen-eliminating device.Through softening as yet the not boiler replenishing water of deoxygenation, circulate with it and between condenser and softened water tank by the condensation cycle pump.
The beneficial effects of the utility model are:
1, native system is simple and reliable, and the flue gas condensing recovery waste heat is directly used in the heating of steam boiler moisturizing, does not need to increase equipment such as waste heat boiler, heat pump.
2, condenser working pressure is low in the native system, thereby has reduced because the condenser that factors such as corrosion cause is revealed accident probability, has prolonged the service life of condenser.
3, adopt the cooling medium of the boiler feedwater of normal temperature as condenser, the condenser heat-transfer effect is good.Compare as cooling medium with adopting air, condenser has characteristics such as heat transfer coefficient height, volume are little, simple in structure.
