Problems solved by technology
[0006] In view of this, the embodiment of the present invention provides a sludge cooperative coal-fired power station coupling disposal system to solve the problem of heavy metal substances and nitrogen contained in the discharged gas that the existing coal-fired power station unit coupling sludge and other biomass fuel systems have not treated. Oxide and volatile substances are processed, resulting in environmental pollution problems

The invention discloses a sludge collaborative coal-fired power plant coupling treatment system. A circulating fluidized bed incinerator incinerates sludge dried by a bubbling drying bed, an induced draft fan introduces flue gas generated by the circulating fluidized bed incinerator into a coal-fired unit, finally the coal-fired unit incinerates and purifies the flue gas after dust removal, so that gas finally exhausted into air does not contain harmful gas, a first dust remover arranged between a flue gas exhaust pipeline and the coal-fired unit is used for removing dust of the flue gas exhausted by the circulating fluidized bed incinerator, heavy metal in the flue gas can be effectively prevented from entering the coal-fired unit, then the heavy metal is prevented from being exhausted through the coal-fired unit, then, through the arrangement of a first heat exchanger and a second heat exchanger, high-temperature gas exhausted by the circulating fluidized bed incinerator can be recycled, and therefore heat energy waste can be effectively avoided by the system, toxic and harmful gas generated by the circulating fluidized bed incinerator can be purified, and the environment is effectively prevented from being polluted.
Description
technical field [0001] The invention relates to the field of coal-fired power generation, in particular to a sludge cooperative coal-fired power station coupling disposal system. Background technique [0002] In recent years, under the influence of national energy conservation and emission reduction and active fiscal policies, urban sewage treatment has developed rapidly, and urban water environment governance has achieved remarkable results. However, a large amount of sludge generated during urban sewage treatment has not been effectively treated and disposed of. Sludge is very easy to cause secondary pollution to groundwater, soil, etc., threatening environmental safety and public health, and affecting the positive effect of the implementation of the national energy conservation and emission reduction strategy. Therefore, as an important part of my country's urban emission reduction, sludge treatment and disposal must take effective measures to effectively promote the imp...
