Description
Technical field
The present invention relates to the incineration disposal and the exhaust heat recovering method of municipal sludge, especially a kind of with the Fluidized Bed Sewage Sludge Incineration Device And Method Thereof of organic heat carrier as the waste heat recovery medium.Belong to the minimizing of municipal sludge, innoxious, disposal of resources field.
Background technology
Municipal sludge is meant solid-state, the semi-solid state waste that city domestic sewage and industrial sewage produce in water treatment procedure, it mainly is made of solid residue and water.Municipal sludge generally contains a large amount of organism, abundant nutrition such as nitrogen phosphorus, heavy metal and pathogenic bacterium and pathogenic bacteria etc., and usually with foul gas, disposes and discharging arbitrarily if do not add, and can cause serious secondary pollution to environment.Along with fast development, increasing day by day of population and the improving constantly of urbanization degree of global economy, the generation of municipal effluent constantly increases.With China is example; the quantity discharged of China's industrial sewage in 2004 and city domestic sewage is respectively 221.1 hundred million tons and 261.3 hundred million tons " .2004 China Environmental State Bulletin-fresh water environment [OL] .2005-06-02, http://www.zhb.gov.cn/eic/649368307484327936/20050602/8204_1.sh tml. compile in State Environmental Protection Administration ".In the sewage purification treating processes, generation is accounted for the mud " Jiang Chengai of the total treatment capacity 0.3%～0.5% of sewage (water ratio is in 97%), Huang Guofeng, Wu Qitang. city sewage and sludge processing and utilizing progress [J]. agricultural environment and development, 1999,16 (1): 13-17. ", how to dispose effectively and reasonably total amount so huge municipal sludge become one important and press for the environmental issue of solution.
The method of disposal of mud is the row of mainly containing sea, landfill, agricultural, burning etc. at present.Compare with preceding 3 kinds of methods of disposal, incineration disposal has the remarkable advantage of minimizing, innoxious and resource utilization.The volume of residue ash has only 10% of mechanical dehydration sludge volume after the sludge incineration; Germ, pathogenic agent all in the burning process are all thoroughly killed, and poisonous and hazardous organism is decomposed by exhaustive oxidation, and the stability of heavy metal improves greatly; The calorific value and the meager coal of dewatered sludge are suitable, but by burning its heat of efficient recovery; Sludge ash can be used as building material, land reclamation agent even sorbent material and uses after suitable physics and chemical process processing.At present, in developed country, the incineration disposal of mud has obtained using quite widely.Denmark 24%, France 20%, Belgium 15%, Germany 14%, the U.S. 25%, the mud of Japan 55% all adopts incineration disposal.Because mud row sea is about to be under an embargo, and mud landfill or agriculturally also will be subjected to more restriction, in future, the ratio that sludge incineration is disposed will improve constantly.
The sludge incinerator of being built before the sixties in 20th century mainly is many thoraxes formula incinerator, because its environmental-protecting performance is not good, multiple hearth furnace loses competitive power gradually.Vertical multiple bedded furnace, jet-type stove and rotary type incinerator also have certain application aspect burning sludge.Fluidized bed incinerator begins to come across Europe the sixties in 20th century, owing to its significant superiority has obtained development rapidly.Compare with the rotary type incinerator with many thoraxes formula incinerator, fluidized bed incinerator has following remarkable advantage: 1. gas-solid mixes strongly in the stove, uniform distribution of temperature field, and flameholding, so sludge incineration is thorough, dioxin emission is extremely low; 2. adopt low temperature, grading combustion technology, oxynitride and heavy metals emission amount are low; 3. can realize low-cost desulfuration in furnace; 4. can use various auxiliary fuels inferior, the efficiency of combustion height; 5. intensity of combustion height, the mud handling capacity in unit cross section is big, compact construction, floor space is little; 6. no mechanical transmission mechanism in the stove is reliable.
Up to now, the special-purpose incinerator of the domestic and international municipal sludge of developing generally all directly burns mechanical dewatered sludge.The water ratio of mechanical dehydration mud higher (generally about 80%), thereby its calorific value is very low, stable burning separately.Therefore, in the industrial application device, adopt the mode of mud and coal or other auxiliary fuel multifuel combustion to carry out the incineration disposal of mud usually.Burn 1kg mechanical dehydration mud, need bituminous coal or other the isocaloric auxiliary fuel of about 0.35kg usually, therefore, carrying out to consume a large amount of coals or other auxiliary fuel when plant-scale municipal sludge burns.The heat that produces in auxiliary fuel such as mud and the coal combustion processes can utilize by the method for waste heat recovery, but when not having enough hot users around the incineration plant, just there is very big problem in the feasibility of this burning mode.
For overcoming the limitation of the mechanical dewatered sludge incinerator of direct burning, the invention provides a kind of dewatered sludge fluidized bed combustion device and method.The mechanical dehydration drying sludge is mainly burned by dewatered sludge with heat and provides, and the burning in fluidized bed incinerator provides insufficient section by coal or other auxiliary fuel, and this method can reduce by about 90% auxiliary fuel consumption.
The drying sludge technology has all realized commercial applications at home and abroad.The medium of sludge-drying comprises hot flue gas, high-temperature water vapor and organic heat carrier (comprising thermal oil and diphenyl mixture, down together) etc.By contrast, organic heat carrier has remarkable advantages such as thermal capacity is big, volumetric flow rate is little, operating pressure is low.At present, the organic heat carrier furnace of exploitation is oil oven or coal-fired grate furnace both at home and abroad.The invention provides a kind of method, to realize organic heat carrier drying sludge technology with the fluidized bed incinerator heated organic heat carrier.
