Description
Technical field
The utility model relates to a kind of drying sludge treatment unit.
Background technology
Along with Chinese society economy and development of city, the generation of municipal effluent constantly increases.In recent years, country all actively supported on policy and financial resources, had built large quantities of municipal sewage plants, and to keep water surrounding, the anti-pollution of harnessing the river promotes the Sustainable development of national economy and ecotope, and the municipal effluent problem progressively is eased.Yet city sewage and sludge is handled and to be still a global technical barrier, mishandlingly will cause serious secondary pollution, and the innocuity treatment problem of mud is increasingly serious.
At present, the method that sewage work adopts usually is a sludge dewatering outward transport landfill disposal, and such processing mode not only pollutes but also take a large amount of soils to environment.Simultaneously, contain elements such as a large amount of organic substances such as nitrogen, phosphorus, potassium in the mud,, can improve the recycle of organic substance if can also be used as agrochemical through effective processing.How the mud of these complicated compositions being done harmless treatment, is to solve China's industrialization development and improve the ecological environment unavoidable important topic.
The utility model content
The purpose of the utility model is to provide a kind of drying sludge treatment unit; The utility model can significantly reduce the volume and weight of mud; And recyclable partial heat energy and waste residue utilize again; Sustainable development to protection environment, promotion national economy and ecotope has remarkable effect, has the important social meaning, meets national industrial policies.
In order to achieve the above object, the technical scheme of the utility model is:
A kind of drying sludge treatment unit comprises the mud pay-off, oar blade type sludge drier, condensing surface, induced draft fan, heating boiler, turbine; Wherein said mud pay-off links to each other with the oar blade type sludge drier, and oar blade type sludge drier water outlet links to each other with heating boiler; Oar blade type sludge drier air outlet links to each other with condensing surface; The air outlet of condensing surface links to each other with induced draft fan, and induced draft fan links to each other with heating boiler; The air outlet of heating stove links to each other with gas-turbine; Gas-turbine links to each other with the inlet mouth of oar blade type sludge drier; The mud mouth of oar blade type sludge drier with heated the furnace bottom mud inlet and linked to each other.
The beneficial effect of the utility model is: the utility model is to the scheme of mud harmless treatment after drying; Utilize the continuous oar blade type sludge drier of waste heat gas as propulsion source; Through utilizing the boiler afterheat steam high water-containing sludge is carried out closed drying; Again mud after the drying is got into boiler combustion and reclaim heat energy; Can significantly reduce the volume and weight of mud, recyclable partial heat energy and waste residue utilize again, are applicable to high moisture materials such as handling various active sludge, downflow sludge, paper mill sludge and various groove slags.The enforcement of the utility model to protecting environment, promoting the Sustainable development of national economy and ecotope that remarkable effect is arranged, has the important social meaning, meets national industrial policies.

Embodiment 1
As shown in Figure 1, a kind of drying sludge treatment unit of present embodiment comprises mud pay-off 1, oar blade type sludge drier 2, condensing surface 3, induced draft fan 4, heating boiler 5, turbine 6; Wherein said mud pay-off 1 links to each other with oar blade type sludge drier 2, and oar blade type sludge drier 2 water outlets link to each other with heating boiler 5; Oar blade type sludge drier 2 air outlets link to each other with condensing surface 3; The air outlet of condensing surface 3 links to each other with induced draft fan 4, and induced draft fan 4 links to each other with heating boiler 5; The air outlet of heating stove 5 links to each other with gas-turbine 6; Gas-turbine 6 links to each other with the inlet mouth of oar blade type sludge drier 2; The mud mouth of oar blade type sludge drier 2 with heated stove 5 bottom mud inlets and linked to each other.The drying sludge treatment process of present embodiment device; Comprise the steps: 1) water ratio is conveyed into oar blade type sludge drier 2 at the mud more than 80% through mud pay-off 1 dehydrates processing, the mud after the mummification is delivered to heat in the stove 5 and burns; The tail gas that produces in the drying process is drained into by oar blade type sludge drier 2 air outlets and carries out condensation in the condensing surface 3 after enter behind the induced draft fan 4 and heated stove 5 tops, and the waste water that produces after the condensation is sent into treatment tank 7; Waste water after 2 mummification of oar blade type sludge drier enters heating boiler 5 through its water outlet; At this moment, through water and tail gas in the heat heating boiler 5 of burning sludge generation, steam gets into again in the oar blade type sludge drier 2 after the heating behind removal objectionable impurities and the stink, as the power that promotes blade in the oar blade type sludge drier 2.Present embodiment utilizes the continuous oar blade type sludge drier of waste heat gas as propulsion source; Through utilizing the boiler afterheat steam high water-containing sludge is carried out closed drying; Again mud after the drying is got into boiler combustion and reclaim heat energy; Can significantly reduce the volume and weight of mud, recyclable partial heat energy and waste residue utilize again, are applicable to high moisture materials such as handling various active sludge, downflow sludge, paper mill sludge and various groove slags.The enforcement of the utility model to protecting environment, promoting the Sustainable development of national economy and ecotope that remarkable effect is arranged, has the important social meaning, meets national industrial policies.
