Abstract
The present invention provides a novel technical device of sludge dehydration and belongs to the solid waste disposal field. The device is applicable to the dehydration and granulation requirements of sludge with various components. A single screw and reverse screw threads and a peculiar structure arrangement are adopted to make the water of the sludge (a moisture content of which is about 80 percent) is dehydrated as a form of liquid, and make the sludge form a sludge dehydration and granulation process, the moisture content of which is 30 percent to 35 percent. A special sludge dehydration and granulation machine fills a blank that the sludge dehydration has to be dehydrated as the form of water vapor, which greatly reduces the energy cost of the sludge dehydration. With small size, low operation cost, high production efficiency, high mechanization degree and wide scope of application, the present invention is a novel and most energy-saving and cleanly-produced sludge dehydration device.
Description
Technical field
The invention belongs to the solid waste treatment facility, be applicable to the needs of the sludge dewatering granulation of heterogeneity.
Background technology
Mud is to carry out in the process of purified treatment at sanitary sewage and industrial wastewater, moves, transforms, precipitates the deposit that forms by the material in the water, or because the bed mud that the sedimentation of suspension in the water body forms.So mud is to be accompanied by all kinds of water purifications and the solid waste that forms, perhaps is semi-solid discarded object exactly.
The characteristic of mud is moisture content height (moisture content about 80%), and volume is big, and content of organic matter height contains multiple metallic element, and particle is thinner, and gas permeability is poor, contains a large amount of active microorganisms.Because the quantity of mud is big, and contains the pollutant of high concentration, therefore,, can cause serious secondary pollution to environment if can not deal carefully with.
Because the moisture content of mud cake is still higher, has fluid properties, causes its follow-up disposal difficulty and cost higher.At present, the direct landfill of many employings, because mud is too loose, can't carry out work such as compacting, covering in Sludge Surface, mud is along with percolate flows into gathering system together, cause leachate collection system to stop up, make the percolate of landfill yard be in unordered flow regime, surrounding environment is caused serious contamination hazard.
The mud cake of high-moisture percentage is not suitable for direct burning equally, must make water evaporates to reduce its moisture by natural air drying or input external heat source.At present, mummification to mud is divided into absolutely dryization (solid content reaches more than 85%) and half-driedization (solid content is about 55%) usually, no matter take any mummification mode, all must import external heat source, moisture in the mud is overcome and mud in bonding force between the colloidal substance become the water of free state, again by the rising temperature, when reaching the evaporation point of water, water evaporates is taken away with flue gas.The mummification equipment that adopts is generally selected drying tumbler for use at present, but floor space is bigger, and equipment investment and operating cost are all higher.
Present technique has proposed the various sludge dewaterings one step completed novel device of granulating, and the moisture in the mud is to deviate from the situation of liquid state, and once finish the process of granulation, the particle that mud is made has that characteristics moisturely are evenly distributed, granulating evenly, be difficult for broken and have elasticity, moisture content stable at 30%-35%, calorific value, keep the original calorific value of mud more than 99%, this will be a technological innovation in the Treatment of Sludge key link, and the reduction of sludge dewatering energy consumption, processing cost are reduced.Thereby broken through traditional mechanical sludge dewatering dehydration rate that is beyond one's reach.
Summary of the invention
The present invention provides a kind of sludge dewatering granulation energy-saving equipment.It has compositions such as sludge feeder, sludge dewatering equipment, eccentric pelleter.Be to be mud below 85% through the mechanical dehydration moisture content; mud in extraordinary mud dehydration extruding granulator dewaterer of the present invention under the synergy of certain temperature, pressure, conditioner; moisture is deviate from liquid form; discharge through drainage arrangement and negative-pressure vacuum device, reduce to 30%-35% through the moisture percentage in sewage sludge of dehydration and once finish through extruding, pelletizing.
Advantage of the present invention is:
1. the moisture of mud is to deviate from the situation of liquid state, greatly reduces the energy consumption of dehydration, has saved a large amount of energy.
2. in the sludge dewatering process, do not lose the original calorific value of mud, because the low organic matter of the temperature of mud does not decompose, can not form steam.
3. mud is granulated and is once finished, and the mud granule moisture distribution is even, wet nuclear phenomenon can not occur, the mud granule particle diameter is even, and diameter is that 2cm-2.5cm, height are the cylinder of 2.5cm, and the particle crushing resistance is difficult for broken by force, be not afraid of moistly and air-dry, easily preserve and carry available conveying worm conveying.
4. the device for dehydrating sladge waste volume is little, and operating cost is low, low noise, and the mechanization degree height, treating capacity is big, and heater can adopt the various energy, non-secondary pollution.
5. this equipment dewaters applicable to various composition mud, can be used for the mud of domestic sewage factory, the mud in paper mill, the mud of printing and dyeing mill, the bed mud in river etc.
6. because the mud granule particle diameter is even, calorific value is stable, is 1000kcal/kg-1400kcal/kg, and the material combustion that can be used for burning can be used for burning for present technique sludge dewatering equipment heater provides the energy, or is used to fire light ceramic etc.
