Description
Technical field
The present invention relates to energy field, is to utilize municipal sludge to be main raw material specifically, produces a kind of new processing method of biofuel.
Background technology
The city domestic sewage and the amount of industrial wastewater of China increase year by year, contain about 1,300,000 tons of sludge quantity (in dry weight) in the sanitary sewage, and annual growth is greater than 10%, particularly at Chinese Urbanization level higher city and geographic town sewage, if all handled, to produce 8,400,000 tons of sludge quantities (in dry weight), mud handling capacity is very outstanding.
European Union member countries implement waste is adopted the stratification management principle of dissolving usually, i.e. recycle, the preferential burning; The U.S. produced 6,900,000 tons of dewatered sludges in 1998, wherein 60% effectively utilized, and comprised directly to effectively utilizations such as soil fertilizings; World developed country has carried out big quantity research to the processing and the utilization that comprise the mud the like waste, has also obtained certain effect.
China is in the starting stage to the processing and the disposal of mud.In the existing sewage treatment facility in the whole nation, mud is had the less than 1/2 of stabilizing treatment facility, treatment process and supporting comparatively perfect less than 1/10, can normally move for number still less; Along with the quickening of Urbanization in China, to the raising of wastewater treatment rate, the treatment capacity of mud grows with each passing day; Objectionable impurities in the mud, as adsorbability organic halogen (AOX), positively charged ion synthetic detergent (LAS), polychlorobiphenyl (PCB) and cadmium, chromium, copper, zinc etc., if mud imposes on soil, heavy metal will accumulate in ground surface, by food chain, at farm crop, animal and human cylinder accumulation; During sludge incineration, can produce a large amount of huge poisonous substance matter,, in addition, also have other potential pollutant such as radioactive pollutant etc. in the mud, deal with improperly, cause serious consequence will for human health and environment as dioxin, furans etc.
Summary of the invention
The objective of the invention is at above-mentioned municipal sludge to have invented a kind of novel method of handling municipal sludge to the problems that environment brings, adopting mud is the main material production biofuel, alleviates fuel oil serious problems in short supply, improves environmental situation.
Utilize processing method that municipal sludge produces biofuel by mechanical dehydration, modified, evaporate, push, stir, react, distill, concoct, filter each operation and form, it is characterized in that:

B) municipal sludge is city trench bottom mud, perhaps sanitary sewage precipitating sludge;
C) solvent is that rapeseed oil, kitchen waste oil, soya-bean oil, peanut oil, Viscotrol C, Semen Maydis oil, a kind of or mixing oil all can;
D) auxiliary agent is methyl alcohol, perhaps hexadecanol;
E) catalyzer is an aluminum chloride;
F) processing method is before mud enters operation, and mechanical dehydration makes moisture percentage in sewage sludge≤65% in advance; Carry out the modified operation of mud then, adding viscosity in mud is the heavy oil of 10MPas, perhaps carbolineum, perhaps adopt the mixing oil of heavy oil and carbolineum, ratio be mud 6-8 doubly, stir; Then, enter evaporization process, make moisture percentage in sewage sludge≤5%; Through screw extrusion press extruding de-oiling, make mud oleaginousness≤7% again; The heavy oil of deviating from returns modified operation again, recycles; When entering agitating procedure, press component prescription and weight percent thereof, in agitator, add solvent, auxiliary agent and catalyzer, fully stirred 10-15 minute through the mud that pushes de-oiling; Then change reaction process over to, reaction process is heated and is 400-600 ℃, and pressure is 5.5-9.0MPa, and the time is 30-60 minute; Distillation process is heated to 360 ℃, is gas oil at 360 ℃ of front-end volatiles oil, and recrement is a charcoal; When changing gas oil over to blending process, add the blending agents amyl nitrate at normal temperatures, its weight percent is 0.2-1.0%, and gas oil should carry out analyzing and testing before entering blending process, the blending agents consumption is determined blending agents amyl nitrate consumption according to the check and analysis result; When gas oil is identical with the every technical performance index of conventional ordinary diesel oil, stop to add blending agents; Enter the filtration operation at last, remove impurity, filtered liquid is qualified refined biometric diesel oil, and impurity returns agitating procedure and utilizes again;
The processing method of utilizing municipal sludge to produce biofuel is a temperature of reaction during for 450-550 ℃, reaction pressure 6.5-8.5MPa, reaction times 40-50 minute.
Positively effect of the present invention is that the employing municipal sludge is that main raw material is produced biofuel, can turn waste into wealth, and alleviates environmental pollution, has reduced product cost; Solvent adopts vegetables oil, and consumption is few, and a large amount of the saving ploughed, and required equipment is conventional traditional petrochemical equipment, and the investment of founding the factory can reduce significantly.
