Technical field
The utility model belongs to heating system Central Plains water treatment device, is specifically related to the de-aerator plant in heating system.
Background technology
Hot water boiler in heating system, boiler hot change during station is industrial production, central heating is supplied water the equipment commonly used.
Boiler is a kind of energy conversion, and the energy to boiler input has chemical energy, electric energy in fuel, and boiler exports steam, high-temperature water or the organic heat carrier with certain heat energy.The original meaning of pot refers to the water container heated on fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two parts.The hot water produced in boiler or steam directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by steam power plant, or by generator, mechanical energy are converted to electric energy again.There is provided the boiler of hot water to be called hot water boiler, be mainly used in life, in industrial production, also have a small amount of application.The boiler producing steam is called steam boiler, often referred to as boiler, is used for thermal power station, boats and ships, locomotive and industrial and mining enterprises.
The main operational principle of boiler be a kind of utilize fuel combustion after waste heat in the heat energy that discharges or industrial production pass to water in container, make water reach the heat power equipment of required temperature or certain pressure steam.Boiler carries out at " pot " and " stove " two portions simultaneously, and after water enters boiler, the heat transmission feedwater that boiler surface will absorb in boiler circuit, makes water be heated into hot water or the generating steam of certain temperature and pressure, by extraction application.In combustion equipment part, fuel combustion constantly releases heat, and the high-temperature flue gas that burning produces, by the propagation of heat, transfer heat to boiler surface, and self-temperature reduces gradually, finally discharged by chimney.
Boiler failure reason in productive life is varied, but general boiler failure is normally relevant with the raw water quality of supply boiler, especially the dissolved oxygen in former water water exceeds standard, dissolved oxygen in oiler feed becomes the depolarizer of cathode process in corrosion reaction, causes steel systeming equipment generation oxygen corrosion.Final product due to corrosion is the oxide compound of iron, therefore can cause again the further deterioration of boiler feedwater quality.
At present, the deaeration plant of former water also also exists deaerating effect difference, complicated operation, and deoxygenation cost is high, and maintenance is inconvenient to wait shortcomings.
