Description
Technical field
The utility model relates to the cleaning Conversion and Utilization technical field of mud, garbage derivatived fuel heat energy, exactly relates to the technique device of mud, garbage derivatived fuel preparation and mud, the generating of garbage fuel high-efficiency environment friendly.
Background technique
One, the present situation of China's waste incineration and generating electricity:
The present rubbish Annual output in China city reaches 1.4 hundred million tons, mud and has reached more than 2,200 ten thousand tons, and with every year about growth rate of about 8% increase progressively.Because domestic main rubbish (mud) treatment technology generally all is the employing sanitary landfills and does not process modes such as namely entering the stove burning and carry out rubbish (mud) processing, wherein sanitary landfill method need take a large amount of soils, and be easy to occur secondary pollution, this processing method obviously is not suitable for.
Since the 1980s, China begins to introduce the application incinerating technology and processes domestic garbage, and utilizes the modernized garbage incinerating power plant of cogeneration.Progress along with science and technology, the generally application of garbage incineration technology, China has the simple burning electricity generation technology of domestic garbage now, be not suitable with the characteristic of China's rubbish, conversion efficiency of thermoelectric low (being 10%-20%) not only, and incineration temperature is inadequate, produce easily toxic and harmfuls such as bioxin etc., has caused common people's's " all waste incinerations must instead " social concern.Simultaneously, sludge incineration disposal energy consumption is large, and cost of disposal is very high, and the sludge treatment rate is low.
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 technique is estimated, and adopt thermogravimetry that the combustion characteristic of RDF has been carried out Primary Study, drawing the RDF technology is feasible in China's application.
