Description
Technical field
This utility model relates to a kind of method to wet sludge treatment and product, particularly relates to a kind of quality coal in cement kiln systems making wet sludge anhydration.
Background technology
Mud is the product generated after Sewage Plant processes waste water.Mud can be divided into dewatered sludge (mud that i.e. water content is few, in lump shape) and wet mud (mud that i.e. water content is more, in magma shape or muddy).The most every ten thousand stere waste water produces wet mud up to 5-10 ton.The wet mud of annual generation the most closely reaches about 40,000,000 tons.Have a strong impact on urban development.Conventional sludge treatment mainly has the means such as sanitary landfills, compost, burning.But all there is the problems such as occupation of land is big, scale is low, secondary pollution is serious, operation investment is high.Cement industry has the function disposing garbage, has obtained international endorsement, owing to the main chemical compositions of mud includes SiO2、Fe203, and A12O3, more similar with the siliceous raw material in cement raw material, can be used to part substituted for silicon raw material in theory and carry out dispensing, and its calorific value can use as fuel.In disposing sludge, functionally there is obvious advantage.Therefore, utilize cement kiln synergic processing town sewage plant mud, be a kind of economy, feasible recycling mode.In order to mud is effectively disposed, the applicant has put into substantial amounts of manpower, material resources, financial resources, carry out prolonged and repeated scientific experiments, the method of the multiple disposing sludge of utility model and product, and within 19th, applied for three patents in December in 2014, be respectively number of patent application be 2014107921661 utility models entitled " a kind of method of cement kiln disposing sludge and sludge gasification quality coal in cement kiln systems ", number of patent application is 2014107916907 utility models entitled " a kind of method of cement kiln disposing sludge and the quality coal in cement kiln systems of disposing sludge ", Application No. 2014107916292 utility model entitled " by the method for cement kiln disposing sludge and with the cement of grate-cooler disposing sludge ".These utility models are created and have been carried out development and utilization after applying for a patent, and to disposing, thick mud effect is fairly obvious, achieves considerable economic benefit and social benefit.Wherein, " a kind of method of cement kiln disposing sludge and sludge gasification quality coal in cement kiln systems " is that wet mud is first made dewatered sludge granule, then is gasified by dewatered sludge granule, then, dore furnace is sent in the combustion gas obtained after gasification, the lime-ash obtained after gasification is sent into Raw Material System.It is the most notable that such wet sludge treating method is disposed effect to thicker wet mud.But, in order to wet sludge gasification must be expended fuel combustion extraly first by wet sludge anhydration, again the sludge incineration after mummification is gasified, the heat that after gasification, heat produced by the combustion gas of gained burns completely less than the mud after mummification, that is, sludge incineration gasification cannot be utilized fully the calorific value of mud, encounter trouble when disposing diluter wet mud.In order to gasify again after the moisture in diluter wet mud is discharged, only by burning mud be far from being enough, also need to expend substantial amounts of fuel (being not only to expend heat energy) extraly gasify, vaporization time is long, therefore, the disposal efficiency of diluter wet mud correspondingly reduces, operating cost increases the most significantly, fails to play cement kiln and disposes the advantage of garbage.Kiln problem is entered in order to solve diluter wet mud, the applicant repeatedly studies and tests, on reasons such as the temperature affecting sludge drying, mud and smoke contacts form, moisture content and mud granule relations, the various factors affecting clinker and quality is carried out comprehensive analysis and summary, finally solves problems of the prior art by long felt and practice.
