Description
Technical field
The utility model relates to discarded fiery explosive and organic liquid waste harmless treatment field, and a kind of incinerator of simultaneously processing discarded fiery explosive and organic liquid waste is provided.
Background technology
Fire explosive has the features such as energy density is high, instantaneous power is large, is widely used at present construction and the production field of military affairs, industrial or agricultural.But gunpowder has certain service life, exceedes service life, its safety and stability will reduce greatly, at this, flammable and explosive substance such as scrap, defective gunpowder finished product in expired gunpowder, production gunpowder process will be referred to as to discarded fiery explosive.These anakinetomers are inflammable and explosive dangerous goods, and the mankind's living safety and Environmental security in the serious threat of arbitrarily throwing aside.Traditional processing method has three kinds: dark soil is buried method, high sea tipping and open incineration method.Though conventional method is simple to operate, disposal cost is low, is attended by the wasting of resources and problem of environmental pollution, does not meet China's strategy of sustainable development.
Explosive industry can produce a large amount of organic liquid wastes in production mother liquor and washing process, its discharge capacity is large, in addition also comprise cooling water, ground and equipment for washing water, complicated component (major pollutants are ethyl acetate, hexogen, propylene butyl ester and acrylonitrile), intractability is large.Conventional liquid waste incinerator mainly contains three kinds: liquid sprays incinerator, rotary kiln incineration stove and incinerator.
The discarded object that fire explosive production factory and applying unit produce in production and application process is to discard fiery explosive and waste liquid as main, arrange that the independent treating apparatus cost of two covers is high, floor space is large, construction and complicated operation, and in waste liquid, contain large quantity of moisture, burning disposal need to be carried out front concentration or add a large amount of fuel combustion supportings separately, has increased greatly operating cost.
Fluidization is applied to chemical industry catalysis industry at first, and last century, the fifties went to coal combustion field.Fluidized bed combustion mode efficiency of combustion is high, NOx discharge capacity is few, desulfuration in furnace cost is low, can use the advantages such as inferior fuel, is paid attention to very much in western countries.Through the development and application of six more than ten years, China's fluidized bed burned-coal technology is also very ripe, has obtained rich experience.
Bubbling incinerator inner lining refractory, forms combustion chamber by air distribution plate below.Combustion chamber is divided into two regions, i.e. the emulsion zone of the dilute-phase zone on top (suspension section) and bottom.In emulsion zone bed, have a large amount of inert bed material (as coal ash or sand etc.), thermal capacity is very large, can meet evaporation, the pyrolysis of organic liquid waste, the requirement of the required amount of heat of burning.The air of being delivered to emulsion zone by air-distribution device makes bed in active fluidization state.In bed, heat-transfer behavior is very superior, and in bed, temperature is uniform and stable, is conducive to the decomposition of organic liquid waste and discarded fiery explosive and burns.Along with air velocity improves, bed starts fluidisation, and has fluid behaviour.Further improve air velocity, bed expansion, superfluous air passes through bed with the form of bubble, and this bubble thoroughly mixes bed material, sets up rapidly the thermal balance of flue gas and particle.In bubbling fluidized bed, empty cross section velocity of flue gas is 1.0～3.0m/s.
Compared with conventional incinerator, on processing organic liquid waste and discarded fiery explosive, bubble type incinerator has the following advantages:
(1) security is good.Discarded fiery explosive burns in stove, if produce microexplosion, surrounding is quartz sand and ash, and the space of upper furnace expansion, all contributes to reduce the power of blast.Make the safe and reliable operation of incinerator.
(2) firing efficiency is high.Incinerator is due to flameholding, and temperature field in furnace is even, and gas and solids mixing in stove are strong, and the evaporation of waste liquid and burning just can complete in moment.Imperfect combustion combustible component burns away in suspension section, makes burning very abundant.
(3) to organic liquid waste and discarded fiery explosive strong adaptability.Owing to there being a large amount of high temperature inert bed material in fluidized-bed layer, the thermal capacity of bed is large, and the required amount of heat of waste liquid evaporation, pyrolysis and burning of low heat value, high-moisture can be provided, so bubble type incinerator is applicable to burning the waste liquid of various moistures and calorific value.
(4) good environmental protection.Incinerator adopts low-temperature burning and fractional combustion, so the growing amount of NOx is very little in burning process, adds suitable additive can eliminate and reduce the discharge of harmful incineration ashes simultaneously in bed material, makes it meet the requirement of environmental protection.
(5) heavy metals emission amount is low.Heavy metal belongs to noxious material, and rising incineration temperature will cause the tenor of dust in flue gas greatly to increase.Because bubble type incinerator incineration temperature is lower than conventional incinerator, therefore heavy metal in flue gas discharge capacity is less.
(6) compact conformation, floor space is little.Because bubble type fluidized bed combustion intensity is high, in unit are, offal treatment ability is large, and furnace heat transfer is strong, also can realize waste-heat recovery device and incinerator is integrated, so whole system compact conformation, floor space is little.
(7) accident rate is low, and maintenance load is little.Bubble type incinerator does not have the movable members of rapid wear, so accident rate and maintenance load are little, and then improves incinerator reliability of operation.
In prior art, process the shortcoming of the technical scheme of discarded fiery explosive: 1) burn insufficient.In fire explosive waste liquid, contain a large amount of organic matters, viscosity is large, taps in incinerator without atomization direct, can cause incineration of liquor effect in stove to reduce; 2) periodic cleaning black dirt, impact is operation normally; 3) operating cost is high.In waste liquid, contain large quantity of moisture, directly burning needs to consume a large amount of combustion-supporting material, greatly increases treatment cost of waste liquor, infeasible economically.4) safety coefficient is low.
