Description
Technical field
The utility model relates to technical field of sludge treatment, particularly relates to a kind of sludge incineration generating equipment.
Background technology
Along with the development of Chinese society economy and urbanization, the generation of municipal sewage and quantity are in continuous growth.According to interrelated data prediction, China's municipal sewage amount also can increase by a fairly big margin in future for 20 years, and within 2010, quantity of wastewater effluent just reaches with regard to 4.4 × 1010m
3d
-1.At present, China produces dewatered sludge nearly 3 × 106t per year, and along with the development of domestic sewage disposal cause, total process water yield of sewage treatment plant and the continuous expansion of degree for the treatment of and raising, the sludge quantity produced also will increase day by day.A large amount of mud fails to obtain in time, reasonably process and become sewage treatment plant's white elephant.
Mud is the product of sewage disposal, composition is very complicated, and it comprises the organic matter, the integrated solid material such as heavy metal element and salt, a small amount of pathogenic microorganism, parasitic ovum that are mixed into the solid particle such as silt particle, fiber, plant and animal residues in sanitary sewage or industrial wastewater and the floccule of condensation thereof, the zoogloea formed by multiple-microorganism and absorption thereof.The key property of mud is moisture content high (can up to more than 99%), and content of organics is high, and easily corruption is smelly, and particle is comparatively thin, and proportion is less, aqueous in colloid.But, also containing a large amount of N, P, K, Ca and organic matter in mud, and N, P are based on organic, can slow releasing, have long-lasting.Mud is useful living resources, if Appropriate application then can not only be turned waste into wealth, can also increase economic benefit.
Sludge incineration is a kind of technique of Treatment of Sludge.Mud is put into incinerator and is burned by it together with raw coal, with the organic matter in high-temperature oxydation mud, makes mud become a small amount of ashes.The sludge moisture content sent by sewage treatment plant is more than 90%, calorific capacity is at about 1200kj/kg, therefore must carry out drying to mud before burning, make the water content of mud be down to about 30%, calorific capacity is approximately 6000kj/kg and mud could be sent into burner hearth and burn.Publication number is 103388825A, publication date is that the Chinese patent of 2013-11-13 discloses a kind of mud raw coal and mixes and join boiler electrification technique as well as, first the mud of moisture content less than 80% is mixed with raw coal, again the mud mixed and raw coal are delivered to boiler coal bunker, send coal pulverizer to, high warm air heating mixture is passed in coal pulverizer, and by mixture pulverize, finally the mixture of powdery is delivered to powder storehouse, by mill exhauster, the mixture of powdery is delivered to boiler corner and enters boiler combustion, although this technique can complete and carry out burning disposal to mud, but need to use coal pulverizer and high-temperature blower to carry out drying and micronization processes to mud, the input of incinerator is very large, exacerbate the financial burden of Treatment of Sludge so especially, hinder applying of sludge incineration process.
