Description
Technical field
The utility model relates to a kind of eddy flow high-velocity jet sludge drier, belongs to technical field of sludge treatment.
Background technology
Along with China's level of urbanization improves constantly, sewage treatment facility construction has obtained high speed development, according to the sludge treatment treatment depth investigation of < < 2013-2017 China and investment strategy planning application report > > statistics China's urban wastewater treatment firm in 2010, had more than 2500, municipal sewage treatment ability has reached 1.22 hundred million tons of every days, for realizing national reduction of discharging target and water surrounding, improve, made huge contribution.But a large amount of excess sludges have been supervened in the construction of Sewage Plant and operation, in water ratio 80%, the whole nation year total water production rate of mud will break through 3,000 ten thousand tons very soon, and sludge treatment situation is very severe.
Because China's Sewage Plant is in process of construction, " the light mud of heavy water " for a long time, China's urban wastewater treatment firm has been realized the preliminary minimizing of mud substantially, but the stabilization treatment of unrealized mud.According to prediction net statistics, approximately 80% Sewage Plant has the thickening facility of mud, has reached minimizing to a certain degree; Approximately there is 80% mud without stabilization treatment, in mud, contain the pollutents such as repugnant substance, pathogenic agent, persistent organism and transfer to land from sewage, cause pollutent further to spread, the environment reduction of discharging benefit of building up the large sewage treatment facility putting into operation is had a greatly reduced quality.According to statistics, at present in disposal options, landfill accounts for 63.0%, sludge aerobic fermentation+agricultural accounts for 13.5%, mud nature mummification comprehensive utilization accounts for 5.4%, sludge incineration accounts for 1.8%, mud air storage and outward transport respectively account for 1.8% and 14.4%.In fact, the mud overwhelming majority of landfill, air storage and outward transport belongs to random disposal, and the ratio that really realizes safe disposal is no more than 20%.
Restrict a lot of because have of sludge treatment disposal facility construction, but national sludge treatment disposal general technical route is not clearly one of important restriction factor.The contradiction lagging behind for alleviating sludge yield and sludge treatment ability, China has put into effect a series of policies, planning in recent years.At present, the technological line of China's sludge treatment and industry policy are just progressively able to distinct, and industrialization and the marketization are about to start.Meanwhile, sludge disposal will more and more come into one's own, the technology of sludge disposal, policy and function mode in future soon by all breakthroughs.It is predicted, during " 12 ", sludge treatment is disposed to invest and will be reached 60,000,000,000 yuan, has turned near than Eleventh Five-Year Plan.Sludge treatment is disposed industry and be expected to enter Fast growth phase under policy is promoted.
The utility model relates to a kind of equipment of lignin-sludge, namely processes the equipment of solid waste mud.Existing society occupies very most of to the Contaminated Sewage Sludge of environment, decrement for mud is the key subjects that present society faces, general mud is through pressure filter, with also having more than 80% moisture content after filter or spiral desiccant dehydration, what we will do is more than 80% water ratio this, is reduced to 10% left and right.Present various kinds of equipment all mainly contains stirring, vibrations, extruding etc. to the processing of mud and adds mummification mode, and its mummification effect is not fine.The utility model is for this kind of conventional equipment, and the broken mummification mechanism of mud is transformed.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of device of uniform stirring glue is provided.
The technical scheme providing according to the utility model, eddy flow high-velocity jet sludge drier, comprises equipment cavity, at equipment cavity bottom, is provided with a rotation axis, is staggeredly distributed with some Mechanical Crushing lodicules on rotation axis; Aforesaid device cavity upper end is provided with a dewatered sludge outlet, and equipment cavity lower end is provided with a high pressure gas pipeline, and high pressure gas pipeline one side is also provided with a wet mud entrance.
High pressure gas tube method is installed blue in the pipeline opening of described high pressure gas pipeline.One end of described rotation axis is connected with motor.
The beneficial effects of the utility model: the airflow of high-speed and high-temperature degree for the utility model, transverse impact mud, the chemical combination key that water in mud is combined with mud is broken, can fully be made the moisture content in mud enter in the middle of air, remaining dry ash can reach near 10%.Its dehydrating effect is remarkable.

Embodiment
As shown in Figure 1-2: eddy flow high-velocity jet sludge drier, comprise equipment cavity 2, in equipment cavity 2 bottoms, be provided with a rotation axis 1, on rotation axis 1, be staggeredly distributed with some Mechanical Crushing lodicules 6;
Described equipment cavity 2 upper ends are provided with a dewatered sludge outlet 7, and equipment cavity 1 lower end is provided with a high pressure gas pipeline 4, and high pressure gas pipeline 4 one sides are also provided with a wet mud entrance 3.
High pressure gas tube method orchid 5 is installed in the pipeline opening of described high pressure gas pipeline 4.One end of described rotation axis 1 is connected with motor.
When the utility model is used; utilize the flue gas in flue; about 120-350 ℃; pass through drying air fan; with the speed of 1.5 Mach, tangentially send into SPIN SPOUTED DRYER, mud wet, bulk, through charging machine radial feed kiln ingress, clashes into mutually with the xeothermic gas of the high temperature and high speed tangentially entering; make it particulate and change into the particle below diameter 10mm, and be fierce spouted fluidized state.
The wet mud of airflow crash and mummification carries out Mechanical Crushing while the dry whipping appts being dried by being arranged on kiln bottom.Mud granule in fluidized state, owing to having increased surface-area and having improved the heat and mass transfer coefficient between gas-solid, the moisture content in wet mud evaporates rapidly, is dried.Kiln bottom adopts high speed rotating blade, and per minute approximately 1300 turns, and sense of rotation and flow rotation opposite direction have improved the gas speed surging force of kiln bottom.The dewatered sludge particle that reaches certain mass dryness fraction and granularity (diameter 2mm following) is taken out of outside kiln by air-flow, enters trapping system (cyclonic separator or sack cleaner) and is captured.Leave the humid gas of trapping system, then send into air flue emission.
The airflow of high-speed and high-temperature degree for the utility model, transverse impact mud, breaks the chemical combination key that the water in mud is combined with mud, and that at mud, smashes fully absorbs in a flash heat.Enter into air, air is taken moisture content out of, and the water ratio of excess sludge sharply declines just at this moment.
As shown in Figure 1-2, mud passes through radially access arrangement cavity 2 of wet mud entrance 3, now clashes into the high pressure flue gas that tangential high pressure gas pipeline 4 enters, and makes it micronize and is fierce spouted fluidized state.In this process, mud is by primary breakup mummification, and these mud carry out Mechanical Crushing by the dry whipping appts that is arranged on kiln bottom and again participate in drying process simultaneously.Mud granule in fluidized state, owing to having increased surface-area and having improved the heat and mass transfer coefficient between gas-solid, the moisture content in wet mud evaporates rapidly, is dried.
Motor is by rotation axis 1 driving mechanical broken paddle 6 high speed rotating, and sense of rotation and flow rotation opposite direction, improved the gas speed surging force of kiln bottom.The dewatered sludge particle that reaches certain mass dryness fraction exports 7 by dewatered sludge and is taken out of outside kiln by air-flow, enters trapping system (cyclonic separator or sack cleaner) and is captured.Leave the humid gas of trapping system, then send into air flue emission.
