Description
Technical field
The present invention relates to a kind of
Filtration system
, more particularly to a kind of boiler smoke multiple stage filtration system.
Background technology
Boiler is a kind of energy conversion, has chemical energy in fuel, electric energy, boiler steam of the output with certain heat energy, high-temperature water or organic heat carrier to the energy of boiler input.The original meaning of pot refers to the water container heated on fire, and stove refers to the place of burning fuel, and boiler includes pot and stove two large divisions.The hot water produced in boiler or steam directly for industrial production and heat energy needed for people's lives offer also can be converted to mechanical energy by Steam Power Equipment, or convert mechanical energy into electric energy by generator again.The boiler for providing hot water is referred to as hot-water boiler, is mainly used in life, also has a small amount of application in industrial production.The boiler for producing steam is referred to as steam boiler, is often simply called boiler, is used for thermal power station, ship, locomotive and industrial and mining enterprises.
The main operational principle of boiler is the water that the waste heat in the heat energy or industrial production discharged after a kind of utilization fuel combustion is passed in container, the heat power equipment of temperature or certain pressure steam required for reaching water.Boiler is carried out with " stove " two parts simultaneously at " pot ", and after water enters boiler, in boiler circuit, the heat transfer feedwater for absorbing is made water be heated into the hot water of uniform temperature and pressure or generate steam, is brought out application by boiler heating surface.In combustion apparatus part, heat is constantly released in fuel combustion, and the high-temperature flue gas for producing that burn are transferred heat to boiler heating surface, and self-temperature is gradually lowered, finally discharged by chimney by the propagation of heat.
As time goes on, environmental protection and energy saving become the important directions of China electric power industry structural adjustment, Thermal Power Generation Industry actively pushes forward the upgrading and optimization of industrial structure under the policy guidance of " above pressing greatly little ", the small thermal power unit that large quantities of efficiencies are low, pollution is heavy is closed, the update of domestic thermal power generating equipment is accelerated to a great extent.
Within the following quite a long time, coal-burned industrial boiler will be the leading products of China, and with middle Large Copacity（Separate unit evaporation capacity >=
10t/h
）It is in the majority.But coal-burning boiler can produce serious environmental pollution, as the change and energy-conserving and environment-protective of energy supply structure require that increasingly strictly construction of natural gas fields application will be into the high-speed developing period.Miniature coal Industrial Boiler will move out inner city.Therefore will be the trend of production development using clean fuel and the efficient of clean combustion technique, energy-conservation, low stain Industrial Boiler.
