The invention discloses a kind of CO2 recovery systems based on refuse gasification combustion gas and steam turbine cogeneration, including refuse gasification system, steam generator system, electricity generation system, electricity generation system includes blender, low-pressure air compressor, pressure-air compressor, synthesis flue gas compressor, synthesis smoke combustion room, turbine a, turbine b, steam turbine, generator a, generator b, waste heat boiler, air-water heat exchanger, air vapour gas heat exchanger, synthesis gas vapour gas heat exchanger, recirculation blower, the first separator, the second separator and to water input system.Second separator isolates CO2, N2, remaining vapour gas input synthesis flue gas compressor, and the residual gas that the first separator is isolated inputs refuse gasification system as gasifying agent.It can carry out large-scale rubbish continuous gasification processing, and the organic efficiency of heat is high, and extractable regeneration industrial chemicals, can effectively realize pollutant and CO2 near-zero release.
Description
Technical field
The invention belongs to solid waste incineration Treatment and recovery processing technology field, more particularly to one kind to be based on rubbish
The CO2 recovery systems of gasification burning and steam turbine cogeneration.
Background technology
Existing technology of garbage disposal mainly has burning, sanitary landfills, compost, waste recovery etc..It is conventional in garbage disposal
In technology, burning disposal has that reduced training is obvious, it is innoxious thoroughly, occupation of land amount is small, and waste heat energy is utilized, and secondary pollution is few
The advantages that, meet the strategic requirement of China's sustainable development.But with the continuous improvement to environmental requirement both at home and abroad, how to strengthen
Control to secondary pollution is particularly important.Therefore, refuse pyrolysis gasification burning technology is gradually shifted onto the road of industrial applications
On, especially for domestic rubbish primarily now using all kinds of incineration technologies, gasification burning technology widely industrialize by
The technological innovation of domestic garbage disposal industry is brought to regenerate.
For many years, scientific research of the China to the gasification burning technology such as biomass, rubbish, be in progress a lot of, the base in laboratory
Plinth research is a lot, also has application study, such as：Rotary kiln type, vertical and fluidized bed type destructive gasifying or temperature gasification and high melting skill
Art etc..But Technique Popularizing is applied upper or a definite limitation be present, raw material type, garbage treatment quantity, secondary pollution control and economy
Benefit etc. is principal element.
In existing burning process and equipment, fire grate type incinerator is various informative, and its application accounts for whole world waste incineration
More than the 80% of the total market size, mechanical backstepping fire grate, forwards fire grate or combined fire grate are used in body of heater wherein having, is also adopted
With fire grates such as chain-plate type and drum-types.In boiler plant, boiler recovery heat methods are a lot of, technology maturation；Thermal source kind
Class is also more, such as：The thermals source such as solar energy, smelting furnace waste heat, coal furnace, fluid bed, fixed bed, rotary kiln, heat is reclaimed using boiler
Amount, for generating electricity, heat supply, heating etc..
In summary, typical gasification burning and boiler plant technology maturation, respectively there is its own advantage, but it is actual in China
Need to solve the problems, such as in and deficiency：
1. for characteristics such as China's house refuse water content height, complicated components, the technology of moving hearth uses, to rubbish
Conveying capacity needs emphasis to consider.Fly ash content is higher in flue gas burn simultaneously after, and collecting ash is heavier, deashing repair and maintenance
Cycle is short.
2. with being on the increase for refuse production, sanitary fill such as mountain, garbage treatment quantity must be effectively improved,
It can just meet the market requirement.
3. in face of strict pollutant emission requirement, secondary pollution control is the key problem for technically needing to solve.
4. in order to effectively increase economic efficiency, in rubbish heat treatment process, the organic efficiency of heat needs to improve.It is existing
Rubbish heat treatment technics generally use boiler recovery waste incineration after high-temperature flue gas heat, produce steam shift onto steam turbine hair
Electricity, whole transition heat efficiency losses are larger, handle identical quantity of refuse, relative reduction thermal losses and raising heat exchanger effectiveness can
To improve the thermal efficiency.
For example following patent of existing technology：External combustion wet air gas turbine power generating system (ZL 01120378.1), combustion gas wheel
Machine electricity generation system and its progress control method (ZL 200880007113.7), double-fuel combustion-supporting type gas-steam combined cycle system
System (ZL 200610062631.1), coal powder gas turbine generation system and the process for producing coal powder two-phase flow fuel
(ZL200610062055.0), multiple row sectional drive combined type domestic garbage incinerator (ZL200710092508.9) and two-part
All referred in waste incinerator (ZL201010268376.2) to the problem of：Rubbish heat treatment mode method is not bound with, and
Rubbish heat treatment secondary pollution control, smoke components complexity the problems such as；It is anti-to aoxidize that conventional garbage is heat-treated thermal chemical reaction
Based on answering, reduction reaction auxiliary, secondary pollution is also easy to produce, and burned oxygen quotient is big, First air, Secondary Air infeed amount are big,
Dust content is higher in flue gas, and heat reclaiming system and smoke processing system are had a great influence, and easy dust stratification, exhaust gas volumn is larger,
Relative reduction thermal conversion efficiency；Refuse gasification synthesizes the deep purifying problem of flue gas, it is necessary to synthesize flue gas cleannes after burning
Meet gas turbine requirement, and the application of refuse gasification burning-gas and steam turbine combined cycle generation；Rubbish is heat-treated
The innovation of mode, exhaust gas volumn is reduced, change flue gas composition, chemical reaction environment becomes reduction reaction, the relative raising of the thermal efficiency.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of transition heat efficiency losses are smaller, heat
