Description
Technical field
It is more particularly to a kind of to utilize more than absorption heat pump recovered flue gas the invention belongs to Industrial Boiler and field of energy-saving technology
The method and system of heat.
Background technology
Coal fired power plant is the most important part of China's power generating industry.Although country greatly develops new energy and built in recent years
If progressively control and reduce newly-built coal fired power plant, but coal fired power plant generated energy still accounts for the 70% of national gross generation.In north
Side area, coal fired power plant are also responsible for the important function of heat supply in winter.Quickening and economy recently as Development of China's Urbanization is fast
Speed development, more residential areas and industrial enterprise are built, while the policy of central heating is progressively being implemented, adjoint
Be that many cities breach that heats in the winter time is continuously increased.Therefore, in the case of coal fired power plant total installation of generating capacity constantly reduction,
Need further to excavate unit itself potentiality, waste heat and heat loss are recycled.In the various heat loss of boiler, smoke evacuation
Heat loss is the problem of a worth primary study.
China's coal-fired power station boiler exhaust gas temperature design load is typically between 120~140 DEG C, the smoke evacuation of large-sized station boiler
Heat loss accounts for the 3~8% of power plant's heat loss, while also contains substantial amounts of vapor in discharging fume, and entrained gasification latent heat is huge,
It can be seen that heat loss due to exhaust gas is a kind of abundant cryogenic waste heat resource.In the past, because the presence of flue gas acid dew point causes boiler to arrange
Cigarette temperature can not be too low, otherwise can severe corrosion equipment heating surface and pipeline.With the soaring and energy-saving and emission-reduction of energy prices
The it is proposed of policy, flue gas in power station boiler UTILIZATION OF VESIDUAL HEAT IN receive increasing attention.In the last few years, it is wide with low temperature electrostatic precipitation technology
General application, exhaust gas temperature have already decreased to 90~110 DEG C, in the OK range of the inlet flue gas temperature in wet desulphurization.Through

℃.A large amount of vapor are carried by the saturated flue gas of wet desulfurization system, latent heat of vaporization amount is still huge.
Utilized at present for large-scale coal-fired power station boiler (including most CFB boiler), used smoke pre-heating
Scheme is mainly using low-level (stack-gas) economizer come the waste heat in recovered flue gas.Low-level (stack-gas) economizer is typically located at the upstream of deduster,
Smoke pre-heating is reclaimed by condensate, the waste heat after recovery, or return to the therrmodynamic system of power plant or for as power plant's warm wind
The thermal source of device, or as heat source, heat circulation water for heating.
Limited by heat transfer temperature difference, while in order to prevent the low-temperature corrosion of heating surface, low-level (stack-gas) economizer is designed at present
Mouth cigarette temperature, general control is more than 90 DEG C.At present, low-level (stack-gas) economizer waste heat recovery profit used by most of coal-fired power station boiler
With technology, the heat reclaimed only accounts for 20% of fume afterheat or so.Still there is most obvious heat of smoke and flue gas reclaimed water to steam
The gasification latent heat of gas is underutilized.Therefore develop that a kind of simple system is reliable, efficiency high, obvious heat of smoke can be made full use of
With the heat recovery technology of gasification latent heat, for improving fuel utilization efficiency, reach energy-saving purpose with very heavy
The meaning wanted.
