Description
Technical field
The invention belongs to the sludge of sewage treatment plant dewatering processing device, particularly a kind of mud and lime device for efficient hybrid reaction between.
Background technology
The generation that the processing handling problems of city sewage and sludge is accompanied by sewage treatment plant produces.Mud is the byproduct of the volume maximum that produces in the municipal sewage treatment process, the moisture content height, is difficult for dehydration.Both contained putrefactive organic substance and inorganic nutritive element in the mud, also contained a large amount of pathogens, parasite or ovum, also had heavy metals such as Cu, Zn, Cr and Hg, and the harmful hardly degraded organic substance of part, as polycyclic aromatic hydrocarbons etc.These chemical substances not only can polluted surface water and underground water source, and the foul smell that mud distributes also can contaminated air, and pathogen also is potential threat to human health.
Along with economic development, sewage load increases year by year, and the mud generation also increases sharply.2007 the year end China municipal sewage plant daily handling ability reach 7000 ten thousand steres, growth rate reaches 10.0%; Treatment rate of domestic sewage rises to 59.0% by 19.4% of nineteen ninety-five.To produce the 1t moisture content be that 80% mud calculates by handling 1000 tons of sewage, produces about 2,600 ten thousand t of primary sludge per year.Present about 1,300,000 t of the annual dried mud of discharging of China's municipal wastewater treatment plant, and with annual 10% speed increment.Require according to " State Council is about the decision of the strengthen environmental protection of implementing a scientific outlook on development " and " State Council is about printing and distributing the notice of the comprehensive programme of work of energy-saving and emission-reduction ": by 2010; the wastewater treatment rate that the city, city is established in the whole nation is not less than 70%, 4,500 ten thousand tons of the Eleventh Five-Year Plan period newly-increased daily treatment capacitys of municipal sewage.Municipal sewage treatment amount and mud generation also will further increase.The solution of Treatment of Sludge handling problems is extremely urgent.
Present sludge drying technique comprises heat drying, biological dewatered and lime mummification etc.The heat drying technology is meant under the condition that dewatered sludge externally heats, and by conducting heat and mass transport process, makes the process of water evaporates in the mud.Moisture content difference according to dewatered sludge can be divided into half-driedization and absolutely dryization.Half-driedization technology mainly refers to the finished product moisture content in 35%～50% technology, and absolutely dryization technology refers to mainly that then the finished product moisture content is in the technology below 15%.Heat drying is through the development of decades, ripe technology and equipment have been formed, have advantages such as floor space is little, but the processing cycle is lacked full automatic working, stable, but have also simultaneously that specific investment cost is big, shortcomings such as operating cost and energy consumption height, and exist potential safety hazards such as dust explosion, limited of the promotion and application of mud heat drying technology in China.The sludge organism drying technique is with low cost, and equipment is simple, but shortcoming such as the ubiquity reaction time is long, desiccation apparatus is bulky, mummification efficient are low, percolate and foul smell are difficult to shortcomings such as control.Mud lime drying technique is to add quick lime or white lime in mud, and its temperature is raise, and reaches the mummification purpose.
Dewatered sludge has viscosity height, density height, flowability is poor, particle is thin characteristics, and as thickness, a densification and have thixotropic material, under set mud and lime raw material, how the lime powder mixes with mud on engineering uniformly, is that mud adds a most important link in the lime treatment.
The key that mud adds alkali pretreatment is that mud mixes with the efficient of lime.How to realize that cheap operating cost is that low power consumption, low consumption CaO and good mud physical aspect are the keys of hybrid technology.Comparatively original treating apparatus is to add calcium powder in the worm screw conveyer, and material is main only through the propelling movement process, so the consumption calcium powder is many, mixing is inhomogeneous, weak effect is difficult to realize the improvement of sludge character simultaneously.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the object of the present invention is to provide a kind of mud and lime device for efficient hybrid reaction between, have that mummification is effective, equipment performance stable, simple to operate, operating cost is low, maintaining characteristics easily.
In order to achieve the above object, technical scheme of the present invention is achieved in that a kind of mud and lime device for efficient hybrid reaction between, comprise a cylindrical shell 10, be provided with turning cylinder 11 in the cylindrical shell 10, colter group 8 is installed on the turning cylinder 11, an end of turning cylinder 11 links to each other with the clutch end of the main motor 6 of cylindrical shell 10 outsides, the top of cylindrical shell 10 is provided with charging aperture 3 and exhaust outlet 4, cylindrical shell 10 belows are provided with discharge outlet 7, and the side is provided with discharging opening 9, and the side top of cylindrical shell 10 is provided with air inlet 12.
The place ahead outer setting of described cylindrical shell 10 has auxiliary-motor 15, and auxiliary-motor 15 power output shafts insert cylindrical shell 10 inside, and auxiliary-motor 15 power output shafts are provided with fly cutter 14.
