Description
Technical field
The invention belongs to the heat recovery technology field, relate to a kind of waste incineration flue gas waste heat recovery device.
Background technology
Incinerator flue-gas temperature out is up to 1000～1200 ℃, the inlet temperature that the quench tower of flue gas purification system requires is greater than 500 ℃, therefore the temperature drop from incinerator high-temperature flue gas recoverable out reaches 450～650 ℃, and general residual neat recovering system collocation method is now:
1) directly at the waste incineration outlet of still, waste heat boiler is installed and is come recovery waste heat;
2) the part incinerator is installed air preheater in heat boiler outlet, heats the incinerator combustion air by air preheater.Also there is small refuse incinerator that waste heat boiler is not installed, air preheater only is installed heated combustion air, partially recycled waste heat.
Contain a large amount of HCl in flue gas of refuse burning, HCl has severe corrosive to metal.Under 500～700 ℃, metal is produced high temperature corrosion, under acid dew-point temperature, can produce electrochemical corrosion to metal.When directly in recovered flue gas, the waste heat boiler of waste heat moved, flue gas can contact with the heating surface of waste heat boiler, and because HCl has highly corrosive, the heating surface of boiler is easy to be subjected to the corrosion of HCl and damages.System's running rate is low, maintenance workload is large, brings very large puzzlement for the flue gas of garbage furnace heat recovery.Therefore for fear of waste heat boiler and air preheater corrosion, heat-transfer surface is the following design of employing generally:
1) adopt the alloy material of decay resistance;
2) heating surface at boiler is coated with resistant material;
3) adopt refractory material to be wrapped in the surface of heat-transfer surface, avoid corrosion.
Adopt corrosion resistant alloy material can increase considerably the boiler construction cost, the surface is coated with resistant material can suitably reduce the boiler construction cost, these two kinds of technology all can not solve etching problem fully, can only be the service life of prolonged boiler heat exchanger components, and boiler still needs frequent overhaul.The surface of adopting refractory material to be wrapped in heat exchanger can effectively prevent corrosion, but heat exchange efficiency can significantly descend.
Li Chunqian etc. have introduced a kind of anticorrosion superheater for the incinerator waste heat boiler in application number is 201050778 Chinese patent, introduce superheater surface coverage fire-resistant anticorrosion paint in patent.Although fire-resistant anticorrosion paint can slow down the corrosion of superheater, can not solve the corrosion of superheater fully, other positions of boiler are too at etching problem.
Gong Fei has introduced a kind of smoke air preheater of garbage burning boiler in application number is 102313293 Chinese patent, introduce the heat exchanger tube outside welding evagination pin at the air preheater of metal material in patent, refractory material covers the outer wall of heat exchanger tube, to reach antisepsis.Refractory material can be isolated flue gas and heat exchanger tube effectively, but refractory material can increase considerably the heat exchange resistance.Need to increase considerably the heat exchange area of sky preheater, this patent only relates to air preheater, does not consider the waste heat boiler Anticorrosion.
Bright in being 201010210189.9 patent, application number introduced a kind of garbage burning boiler, the each several part of having introduced boiler in patent forms and structure, the boiler that the inside is introduced can delay coking, burn into dust stratification problem, but still can not solve the etching problem of boiler fully.
Easily produce bioxin due to flue gas of garbage furnace, so require the waste heat boiler flue-gas temperature out must not be lower than 500 ℃ under 200～500 ℃.Be subjected to the impact of waste incineration amount, refuse thermal value, rubbish water content, the flue-gas temperature of waste incineration outlet of still also fluctuates, the waste heat boiler that is arranged on the waste incineration outlet of still can't be regulated the heat exchange amount, so in order to suppress the generation of bioxin, consider the fluctuation of flue-gas temperature, smoke temperature at outlet of waste heat boiler generally can be less than 650 ℃.Therefore there is the waste heat of 150 ℃ to be utilized effectively.
Because waste heat boiler is directly installed on the waste incineration outlet of still, overall heat exchange amount adjustability is very limited, and when the quantity of steam of actual needs is little, the excess steam that boiler produces only has emptying, causes great waste.
