Two, China's garbage derivatived fuel (RDF) development utilization present situation
Nineteen nineties; Set up domestic article one RDF production line cooperatively by Chinese Engineering Thermophysics institute and Japanese IHI company; Carried out the exploration that inflammable matter prepares RDF in the domestic rubbish; Economy to feasibility, environmetal impact and the operation of technology is estimated, and adopts thermogravimetry that the combustion characteristic of RDF has been carried out Primary Study, and it is feasible drawing that the RDF technology uses in China.
Shenzhen permanent letter China day Environmental Protection Technology Co., Ltd; Utilize whole inflammable matters making RDF-5 fuel in the rubbish, utilize the circulating fluidized bed boiler burning electricity generation, efficient has obtained bigger raising (thermoelectric conversion ratio reaches 26%); The discharging of bioxin is better suppressed simultaneously.The said firm's technology has obtained the Tonglu, Zhejiang Province and has contained " the garbage derivatived fuel RDF-5 electrification technique as well as improvement project " that prosperous waste incineration and generating electricity Co., Ltd is assisted in fortune eco-friendly power source Co., Ltd and granary, Jiangsu Province.
Whole inflammable matters prepare RDF-5 fuel in the above techniques make use rubbish, and only adopt the mode of circulating fluidized bed boiler burning electricity generation, make the efficiengy-increasing of garbage power not too big; And because a large amount of plastic components in the RDF-5 fuel, bioxin still has bigger composing machine meeting Zhong burning process;
Three, in sum: the thermal power transfer utilization of conventional garbage burning electricity generation technology and garbage derivatived fuel RDF-5 generation technology, or thermoelectric conversion using rate is low, is easy to generate toxic and harmfuls such as bioxin; Though or can more efficient change sharp rubbish heat energy, the discharging of Dui bioxin also has good inhibitory effect, conversion efficiency of thermoelectric is with the watershed management technology of bioxin still has very big lifting optimization space.And garbage derivatived fuel (RDF-6) the gas-steam combined circulation electric generating apparatus that the utility model proposes is the technical products that for environmental protection, efficiently utilizes the garbage derivatived fuel generating to develop.
The model utility content
The utility model is to the thermal power transfer utilization of conventional garbage burning electricity generation technology and garbage derivatived fuel RDF-5 generation technology, or thermoelectric conversion using rate is low, is easy to generate toxic and harmfuls such as bioxin; Though or the discharging of can more efficient changing sharp rubbish heat energy Dui bioxin also has good inhibitory effect; But conversion efficiency of thermoelectric is with the watershed management technology of bioxin; Still have very big lifting optimization space, propose a kind of garbage derivatived fuel gas-steam combined circulation electric generating apparatus, to overcome the problems referred to above that existing technology exists.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is following:
Garbage derivatived fuel gas-steam combined circulation electric generating apparatus; Comprise garbage sorting device, RDF-6 preparing apparatus, gas turbine generator group; Wherein garbage sorting device is used for being used to prepare RDF-6 fuel with the mixed consumer waste sorting and with the plastics that sub-elect; The garbage sorting device rear end connects the RDF-6 preparing apparatus; The RDF-6 preparing apparatus is used for the plastics that refuse classification goes out are prepared as the RDF6 liquid fuel, and RDF-6 preparing apparatus rear end connects the gas turbine generator group, and the gas turbine generator group is utilized RDF-6 fuel acting generating and discharged high-temperature fuel gas.
In technique scheme; Said gas turbine generator group rear end is connected with exhaust heat boiler; The high-temperature fuel gas that exhaust heat boiler utilizes the gas turbine generator group to discharge produces high temperature and high pressure steam; The outlet of exhaust heat boiler is connected with the import of vapor wheel generator set, the high temperature and high pressure steam acting generating that the vapor wheel generator set utilizes exhaust heat boiler to produce.
